    Authors: Nasiri, Mina;

    This research concerns the way of facilitating the occurrence of disruptive innovation for sustainability by Internet of Things (IOT) solutions. One of the main objectives of this thesis is to find connections between IOT solutions, disruptive innovation, and sustainability. Moreover, this thesis critically review the research related to this topic to reveal future research areas in this field. In order to achieve the objectives of this thesis, research has been conducted towards three different aspects. The first aspect is to find the challenges of disruptive innovation for sustainability. The second one is to seek the value creation by IOT solutions in social, economic, and environmental dimensions of sustainability. The last aspect is to find the way of promoting the performance of circular economy by IOT technology. Finally, this thesis has been complemented with real-world perspectives from the conducted expert interview. The previous research studies have provided a valuable insight into the knowledge of IOT. However, according to the knowledge of the author, most of these studies have focused on the application of IOT in different industries, and no studies have inclusively examined the impact of IOT in each dimension of sustainability. The results show that IOT opens up a new room for revolution by embedded RFID tags, sensors, and actuators in objects. The solutions provided by IOT offer a possibility to economic, industrial, and business development. These solutions improve not only the social sustainability but also environmental sustainability because of the provision of peoples’ facilities to have a safe, secure, and eco-friendly life.

    Authors: Smakiqi, Ariana;

    The digitized world is creating more and more opportunities for companies to achieve growth. It also brings certain requirements to the table if a company wants to be successful in the future markets. The direction businesses are going towards is considering more customer experience, product and service lifecycle, and sustainability. Industrial manufacturing companies are usually the ones following two steps behind. It is often hard to start implementing such a big change in a company that has traditionally only focused on producing a product and not taking the final customer experience into consideration at all. With this one-way of doing business, customer needs and sustainability issues get left behind. This way of doing business is an old way that will not help the company in the future. The goal of this thesis is to find out whether industrial manufacturing companies do service design and use the possibilities of Internet of Things for it, or if they do have it even on their radar. This thesis also aims to find out what kind of needs and goals these companies have for finding out whether servitization would benefit them. The first part of the thesis is built by comprehensively approaching the subject from a theoretical point of view. The literature review presented in this thesis gives a solid ground for the topics and analyzing the results of the empirical section, the second part of the thesis in order to provide encompassing information. This thesis uses an online survey questionnaire as a research method. A link to the survey was sent to employees of different industrial manufacturing companies globally. A total of 18 survey responses were received anonymously. The results gathered from the obtained data in the empirical part show that industrial manufacturing companies have certain needs which could be fulfilled by using service design and Internet of Things. Results also clearly show that service design implementation is not at a good level due to a lack of knowledge about this topic and its benefits. This thesis provided a solution for industrial manufacturing companies to achieve their business goals in a sustainable and profitable way. By implementing service design and using Internet of Things platforms, these companies could benefit in the longer run. Erilaiset digitaaliset alustat luovat yrityksille valtavasti kasvumahdollisuuksia. Markkinoilla on kova kilpailu, joten tiettyjen vaatimusten on täytyttävä, mikäli yritys tähtää menestymiseen. Asiakaskokemukseen panostaminen, tuotteiden sekä palvelujen elinkaaresta huolehtiminen ja kestävyys ovat kaikki keskeisessä roolissa. Teolliset valmistavat yritykset ovat aina vähän jäljessä muista yrityksistä, kun puhutaan muutoksista. Usein on vaikea aloittaa tällaisen suuren muutoksen toteuttaminen yrityksessä, joka on perinteisesti keskittynyt vain tuotteen tuottamiseen eikä niinkään lopullisen asiakkaan tarpeiden huomioimiseen. Tämä yksisuuntainen liiketoiminta ei niinkään ota asiakastarpeita tai kestävää kehitystä huomioon. Tämä vanha perinteinen toimintamalli on jätettävä taakse. Tämän diplomityön tavoitteena on selvittää, käyttävätkö nämä yritykset palvelumuotoilua sekä Internet of Things -alustoja. Diplomityössä selviää myös minkälaisia tarpeita ja tavoitteita näillä yrityksillä on, joita voisi tyydyttää palvelullistamisen avulla. Diplomityön ensimmäinen osa on kirjallisuuskatsaus, joka auttaa lukijaa ymmärtämään aihetta kokonaisvaltaisesti. Tässä diplomityössä esitetty kirjallisuuskatsaus antaa vankan pohjan empirian, työn toisen osan, tulosten analysoimiseksi. Työssä käytetään online-kyselylomaketta tutkimusmenetelmänä. Linkki kyselyyn lähetettiin eri teollisuusyritysten työntekijöille maailmanlaajuisesti. Yhteensä 18 vastausta saatiin nimettömästi. Empiirisestä osiosta saaduista tuloksista selviää, että teollisilla valmistavilla yrityksillä on tietynlaisia tarpeita, joita voitaisiin tyydyttää hyödyntämällä palvelullistamista ja Internet of Things -alustoja. Tulokset osoittavat myös selvästi, että palvelumuotoilun toteutus ei ole hyvällä tasolla näissä yrityksissä, koska tästä aiheesta ja sen eduista ei tiedetä tarpeeksi. Tämä diplomityö tarjoaa ratkaisun näille yrityksille liiketoimintatavoitteiden saavuttamiseksi kestävällä ja kannattavalla tavalla. Keskittymällä enemmän palveluiden tarjoamiseen tuotteiden tuottamisen sijaan, nämä yritykset hyötyisivät pidemmällä aikavälillä.

    Authors: Nurgazy, Meruyert;

    Air pollution is a severe issue in many big cities due to population growth and the rapid development of the economy and industry. This leads to the proliferating need to monitor urban air quality to avoid personal exposure and to make savvy decisions on managing the environment. In the last decades, the Internet of Things (IoT) is increasingly being applied to environmental challenges, including air quality monitoring and visualization. In this thesis, we present CAVisAP, a context-aware system for outdoor air pollution visualization with IoT platforms. The system aims to provide context-aware visualization of three air pollutants such as nitrogen dioxide (NO2), ozone (O3) and particulate matter (PM2.5) in Melbourne, Australia and Skellefteå, Sweden. In addition to the primary context as location and time, CAVisAP takes into account users’ pollutant sensitivity levels and colour vision impairments to provide personalized pollution maps and pollution-based route planning. Experiments are conducted to validate the system and results are discussed.

    Authors: Hatara, Ella;

    The goal of this Master’s thesis is to respond to the sustainability challenges of the current fashion industry with two emerging themes, the circular economy and digitalization. The aim of the work was to research the current status of the digitalization of the Finnish fashion industry, the opportunities provided by utilization of digital tools with the contribution to circular economy, and the possible challenges related to them, based on a literature review and company examples. Due to low level of digitalization in the Finnish fashion industry, solutions for the life cycle stages of design, manufacturing, retail, and extended use phase have been sought with the help of examples from literature. According to circular economy principles, clothing should be designed to last both physically and aesthetically, minimizing raw material use. Digitally aided tools and data can be used in designing, which enables the consideration of the whole life cycle already in designing stage. The Internet of Things (IoT), Blockchain and other technologies, which create a digital twin of manufactured products, enables tracking clothes in retail and possibly even in recycling. Supply chain and production transparency and other relevant product-related information can be easily made accessible to consumers with tags that can be read through mobile devices. Companies and third-party services offer solutions to extend the lifespan of products, such as repair services and trading of used clothing. The resource requirements of digital technologies and tools can become a challenge. However, the low level of digitization in the fashion industry can be seen as Finland's advantage, as it enables the design of a seamless digital system without path dependencies. Tämän diplomityön tavoitteena on vastata nykyisen muotiteollisuuden kestävyyshaasteisiin kahdella keskeisellä nousevalla teemalla, kiertotaloudella ja digitalisaatiolla. Työn tavoitteena oli kirjallisuuskatsauksen ja yritysesimerkkien avulla selvittää Suomen muotiteollisuuden digitalisoitumisen nykytila, digitaalisten työkalujen tuomat mahdollisuudet ja kontribuutio kiertotalouteen, sekä mahdolliset haasteet niihin liittyen. Suomen muotiteollisuuden digitalisaation alhaiseen lähtötasoon on etsitty kirjallisuuden esimerkkien avulla ratkaisuja suunnittelun, tuotannon, myynnin ja käyttöiän pidentämisen elinkaarivaiheisiin. Kiertotalousperiaatteiden mukaisesti vaate tulee suunnitella kestämään aikaa niin fyysisesti kuin esteettisesti käyttäen mahdollisimman vähän raaka-aineita. Suunnittelussa voidaan hyödyntää digitaliavusteisia työkaluja ja dataa, jonka avulla koko elinkaari voidaan huomioida jo suunnitteluvaiheessa. Esineiden internet, lohkoketjut ja muut tuotannon teknologiat, jotka luovat digitaalisen version tuotteista, mahdollistavat vaatteiden seurannan myynnissä ja mahdollisesti jopa kierrätykseen asti. Toimitusketjun ja tuotannon läpinäkyvyys ja muu olennainen tuotteeseen liittyvä tieto voidaan tuoda helposti kuluttajien ulottuville mobiililaitteilla luettavien merkkien kautta. Tuotteiden käyttöiän pidentämiseksi, kuten korjauspalveluihin ja käytettyjen vaatteiden myyntiin ratkaisuja tarjoaa yritykset ja kolmannen osapuolen palvelut. Digitaalisten teknologioiden ja työkalujen resurssivaatimukset voivat osoittautua haasteeksi. Alhainen digitalisaation taso muotiteollisuudessa voidaan kuitenkin nähdä Suomen etuna, sillä se mahdollistaa saumattoman digitaalisen systeemin suunnittelun ilman polkuriippuvuutta.

    Authors: Mazurovskiy, Mikhail;

    The goal of this research is to specify requirements and create the high-view architecture of the Internet of Things system applied in greenhouse farming. The research was conducted based on the Middle East pharmaceutical company producing medicines made of cannabis. Four direct users of the system representing three main user groups were interviewed on the requirements elicitation stage. The collected requirements were specified separately according to their types. The level of detail of specified requirements enabled the creation of several architectural views. The developed architecture is based on a wireless sensor network, wired actuators network, and cloud-based IoT platform. The main elements used in the solution are devices provided by Libelium and cloud-based services offered by Amazon Web Services. The specified requirements and developed architecture were verified and validated by representatives of the pharmaceutical company and third-party IoT expert.

    Authors: Leinonen, Jari;

    This research investigates whether the weather balloon observation system can be made environmentally friendly. Through literature and patent search, combined with theory of inventive problem solving (TRIZ) methods, alternative materials and operations to the current system model are analyzed. Focusing on solutions applicable to the target environment, goal and budget, changes to the current policies are proposed. Furthermore, the findings are tested through two field experiments, with the objective of providing empirical data to the study as well as demonstrating proof-of-concept systems, as alternatives to the current one. By focusing on key features, this research seeks to gain a holistic view of the current and future operating models, consequently enabling the management level of relevant organizations to consider the proposed changes with all the necessary information at hand. These changes include (but not limited to) improving the current tracking method to allow easier retrieval of launched radiosondes, a biodegradable shell structure, color changes, a network receiver system based on existing field equipment, an open access database, and landing coordinate prediction and reporting model for the public. This research contributes not only to the available literature but also to the operational models, by suggesting more environmentally friendly ways of conducting high-altitude weather observations through radiosonde technology. Tämä tutkimus pyrkii selvittämään, voidaanko säähavaintopallojärjestelmä tehdä ympäristöystävälliseksi. Kirjallisuuden ja patenttihaun avulla, yhdistettynä keksinnöllisten ongelmanratkaisumenetelmien (TRIZ) teoriaan, analysoidaan vaihtoehtoisia materiaaleja ja toimintoja nykyiselle järjestelmämallille. Kohdeympäristöön, tavoitteeseen ja budjettiin keskittyvien ratkaisujen kautta voidaan nykyisiin käytäntöihin ehdottaa muutoksia. Lisäksi löydöksiä testataan kahdella kenttäkokeella, joiden tavoitteena on tuottaa tutkimukseen empiiristä tietoa sekä esitellä konseptit vaihtoehtoina nykyiselle järjestelmälle. Keskittymällä järjestelmien keskeisimpiin piirteisiin tämä tutkimus pyrkii luomaan kokonaisvaltaisen kuvan nykyisistä ja tulevista toimintamalleista, jolloin asianosaisten organisaatioiden johto saa kaiken tarvittavan tiedon ehdotettuja muutoksia käsitellessään. Näihin muutoksiin lukeutuvat muun muassa nykyisen seurantamenetelmän parantaminen lähetettyjen radiosondien jäljittämisen ja palauttamisen helpottamiseksi, biohajoava kuorirakenne, värimuutokset, olemassa oleviin kenttälaitteisiin perustuva vastaanotinverkko, avoimen pääsyn tietokanta sekä julkinen laskeutumiskoordinaattien ennustus- ja raportointimalli. Tämä tutkimus tukee aihealueesta saatavilla olevaa kirjallisuutta sekä myös toimintamalleja ehdottamalla ympäristöystävällisempiä tapoja suorittaa ilmakehän radiosonditekniikkaan perustuvia säähavaintoja.

    Authors: Ghoreishi, Malahat;

    The digital transformation and circular economy (CE) are two megatrends that have been discussed not only among practitioners and policy makers, but also as an interesting topic of research in the scientific world. While CE aims to transform the world economy model to a more sustainable and eco-friendlier version, digital technologies (DTs) are revolutionizing our everyday lives by offering innovative connected solutions. Implementing CE strategies offers considerable value by decoupling our production and consumption system from the linear model of ‘take-make-use-dispose’. However, applying CE principles requires a radical change in the way companies create and deliver value to their customers. Companies face challenges in aligning CE principles to their current system to offer service-oriented models instead of physical products. This raises the role of DTs as enablers of CE. In this sense, AI has been identified as one of the key DTs that can enhance circularity through advanced analytics capabilities. Utilising AI enables resource and energy efficiency that can help companies in making more resourceful decision-making. However, research on the effective utilisation of AI in circular value creation has been very limited and companies struggle to understand how AI can change their value creation model based on CE strategies. Addressing this gap, it is essential to develop the understanding of potential of AI in circular value creation. This thesis employs a mixed methods approach to answer the main research question: “How can AI enhance circular value creation for companies and related business models?”, starting with a conceptual approach to improve the concept of value creation in CE and reveal the role of AI in the ReSOLVE framework. This is followed by empirical investigations through qualitative studies on product design and business model (BM) aspects of circular value creation. Since qualitative studies of this dissertation emphasise the role of data in digitally enabled CE, a literature review was conducted to identify the aspects and value of data in AI-enabled BMs, following by an empirical examination of the conceptual model by the last study. The results contribute and add new knowledge to the field of AI and value creation in CE by providing detailed information on how AI can enhance resource and energy efficiency when applied in circular solutions. The findings demonstrate that AI can enhance circularity by enabling data-driven BMs such as product-service systems and the sharing economy. In addition, the results highlight the value of data for example in product design and prototyping, and the entire lifecycle of products to innovate AI-enabled BMs. The thesis identifies that an innovative business ecosystem which is connected by different DTs can enhance circularity for all the actors and partners of ecosystem through sharing transparent data that circulates within the supply chain.

    Authors: Nousiainen, Jalo;

    The field of exoplanet research is one of the most rapidly expanding research fields in modern astrophysics. In recent decades, astronomers have found most exoplanets via indirect techniques such as the transit and radial velocity method. The direct imaging technique called high contrast imaging (HCI) enables new ways to expand our knowledge of these exoplanets and exoplanetary systems. However, direct imaging of exoplanets is challenging due to the high contrast ratio and small angular separation from the host star. Thus, HCI detections, so far, are mostly limited to a few dozen young and luminous giant exoplanets. The new generation of HCI instruments, under development, will push direct imaging into increasingly challenging areas, discovering and characterizing exoplanets dimmer and closer to their host start. The ultimate goal is direct imaging and characterization of potentially habitable exoplanets. On ground-based telescopes, HCI instruments are equipped with eXtreme Adaptive Optics (XAO) that correct the phase fluctuations caused by the atmosphere. With an optimized instrument design, the residuals left by XAO correction set the limitation of sensitivity; thus, minimizing the XAO residuals is a crucial objective for ground-based HCI. Further, most habitable exoplanets are located at small angular separations from their host stars, where current XAO control algorithms leave strong residuals of stellar light that could be suppressed with more advanced algorithms. This thesis explores novel data-driven control methods for XAO control that cope with crucial limitations of traditional control laws, such as temporal delay and calibration errors. Improvement in these potentially reduces the residual flux of stellar light in the coronagraphic point spread function and thus enables fainter observations closer to the host star. We show that model-based RL is a promising XAO control approach that produces consistent results in numeric simulations and lab setups. The proposed methods suppress the temporal error, and photon noise compensates for misregistration and optical gain. It can also adapt to changing wind conditions in time scales of several seconds. Moreover, model-based RL manages the extreme time constraint of XAO control and, if well formulated, scales to ELT scale XAO.

    Authors: Gubanov, Aleksandr;

    Smart grasping means that a robot can automatically decide which object and how an object can be grasped. Firstly, a neural network should find the objects and get a 2D bounding box. The convolution neural network is used for processing the frames to detect the objects. Secondly, a proposed approach should support the robot to understand where it is possible to grasp the object. The decision should be done independently and autonomously such that reliable grasping becomes possible. In the experiment there are only a limited set of known objects. The quick addition of new objects is possible since an automatic process for extracting new objects from video was developed. The result of the thesis provides an automated system which connects the recognition system and the robot.

    Authors: Sommarberg, Mikael;

    The Hazardous Analysis and Critical Control Points (HACCP) process is an essential process in many fields, such as, the food processing field. In this process, a pen and paper have generally been used for documentation but some of the operators in this field have started using a digital solution for it. The main purpose of this master’s thesis is to add value to the HACCP process by integrating the documented data from the case company’s application to a client’s ERP system. As the results of this research, a software integration was developed for this data synchronization and the potential benefits of it and the digitalization of HACCP were researched. In the qualitative research, it was found out that the benefits of the digitalization of HACCP process correlate quite well with the typical benefits of process digitalization. Elintarvikkeiden omavalvonta on oleellinen osa monien eri alojen, esimerkkinä ruoan käsittely alan, arkipäiväisissä toiminnoissa. Monesti tähän prosessiin käytetään edelleen kynää ja paperia, mutta osa prosessia suorittavista toimijoista on siirtynyt digitaalisiin ratkaisuihin. Tämän diplomityön päätarkoitus on lisätä arvoa omavalvontaprosessiin synkronoimalla prosessin suorituksesta kerätyt tiedot (esimerkiksi mittausdata) prosessin suorittaja yrityksen toiminnanohjausjärjestelmään. Tuloksena luotiin ohjelmistointegraatio tapausyrityksen sovelluksen sekä asiakkaan toiminnanohjausjärjestelmän välillä sekä kartoitettiin sen, ja omavalvonnan digitalisoinnin hyötyjä. Laadullisessa tutkimuksessa havaitut hyödyt korreloivat osittain tyypillisten digitalisaatiosta saatavien hyötyjen kanssa.

    Authors: Nasiri, Mina;

    This research concerns the way of facilitating the occurrence of disruptive innovation for sustainability by Internet of Things (IOT) solutions. One of the main objectives of this thesis is to find connections between IOT solutions, disruptive innovation, and sustainability. Moreover, this thesis critically review the research related to this topic to reveal future research areas in this field. In order to achieve the objectives of this thesis, research has been conducted towards three different aspects. The first aspect is to find the challenges of disruptive innovation for sustainability. The second one is to seek the value creation by IOT solutions in social, economic, and environmental dimensions of sustainability. The last aspect is to find the way of promoting the performance of circular economy by IOT technology. Finally, this thesis has been complemented with real-world perspectives from the conducted expert interview. The previous research studies have provided a valuable insight into the knowledge of IOT. However, according to the knowledge of the author, most of these studies have focused on the application of IOT in different industries, and no studies have inclusively examined the impact of IOT in each dimension of sustainability. The results show that IOT opens up a new room for revolution by embedded RFID tags, sensors, and actuators in objects. The solutions provided by IOT offer a possibility to economic, industrial, and business development. These solutions improve not only the social sustainability but also environmental sustainability because of the provision of peoples’ facilities to have a safe, secure, and eco-friendly life.

    Authors: Smakiqi, Ariana;

    The digitized world is creating more and more opportunities for companies to achieve growth. It also brings certain requirements to the table if a company wants to be successful in the future markets. The direction businesses are going towards is considering more customer experience, product and service lifecycle, and sustainability. Industrial manufacturing companies are usually the ones following two steps behind. It is often hard to start implementing such a big change in a company that has traditionally only focused on producing a product and not taking the final customer experience into consideration at all. With this one-way of doing business, customer needs and sustainability issues get left behind. This way of doing business is an old way that will not help the company in the future. The goal of this thesis is to find out whether industrial manufacturing companies do service design and use the possibilities of Internet of Things for it, or if they do have it even on their radar. This thesis also aims to find out what kind of needs and goals these companies have for finding out whether servitization would benefit them. The first part of the thesis is built by comprehensively approaching the subject from a theoretical point of view. The literature review presented in this thesis gives a solid ground for the topics and analyzing the results of the empirical section, the second part of the thesis in order to provide encompassing information. This thesis uses an online survey questionnaire as a research method. A link to the survey was sent to employees of different industrial manufacturing companies globally. A total of 18 survey responses were received anonymously. The results gathered from the obtained data in the empirical part show that industrial manufacturing companies have certain needs which could be fulfilled by using service design and Internet of Things. Results also clearly show that service design implementation is not at a good level due to a lack of knowledge about this topic and its benefits. This thesis provided a solution for industrial manufacturing companies to achieve their business goals in a sustainable and profitable way. By implementing service design and using Internet of Things platforms, these companies could benefit in the longer run. Erilaiset digitaaliset alustat luovat yrityksille valtavasti kasvumahdollisuuksia. Markkinoilla on kova kilpailu, joten tiettyjen vaatimusten on täytyttävä, mikäli yritys tähtää menestymiseen. Asiakaskokemukseen panostaminen, tuotteiden sekä palvelujen elinkaaresta huolehtiminen ja kestävyys ovat kaikki keskeisessä roolissa. Teolliset valmistavat yritykset ovat aina vähän jäljessä muista yrityksistä, kun puhutaan muutoksista. Usein on vaikea aloittaa tällaisen suuren muutoksen toteuttaminen yrityksessä, joka on perinteisesti keskittynyt vain tuotteen tuottamiseen eikä niinkään lopullisen asiakkaan tarpeiden huomioimiseen. Tämä yksisuuntainen liiketoiminta ei niinkään ota asiakastarpeita tai kestävää kehitystä huomioon. Tämä vanha perinteinen toimintamalli on jätettävä taakse. Tämän diplomityön tavoitteena on selvittää, käyttävätkö nämä yritykset palvelumuotoilua sekä Internet of Things -alustoja. Diplomityössä selviää myös minkälaisia tarpeita ja tavoitteita näillä yrityksillä on, joita voisi tyydyttää palvelullistamisen avulla. Diplomityön ensimmäinen osa on kirjallisuuskatsaus, joka auttaa lukijaa ymmärtämään aihetta kokonaisvaltaisesti. Tässä diplomityössä esitetty kirjallisuuskatsaus antaa vankan pohjan empirian, työn toisen osan, tulosten analysoimiseksi. Työssä käytetään online-kyselylomaketta tutkimusmenetelmänä. Linkki kyselyyn lähetettiin eri teollisuusyritysten työntekijöille maailmanlaajuisesti. Yhteensä 18 vastausta saatiin nimettömästi. Empiirisestä osiosta saaduista tuloksista selviää, että teollisilla valmistavilla yrityksillä on tietynlaisia tarpeita, joita voitaisiin tyydyttää hyödyntämällä palvelullistamista ja Internet of Things -alustoja. Tulokset osoittavat myös selvästi, että palvelumuotoilun toteutus ei ole hyvällä tasolla näissä yrityksissä, koska tästä aiheesta ja sen eduista ei tiedetä tarpeeksi. Tämä diplomityö tarjoaa ratkaisun näille yrityksille liiketoimintatavoitteiden saavuttamiseksi kestävällä ja kannattavalla tavalla. Keskittymällä enemmän palveluiden tarjoamiseen tuotteiden tuottamisen sijaan, nämä yritykset hyötyisivät pidemmällä aikavälillä.

    Authors: Nurgazy, Meruyert;

    Air pollution is a severe issue in many big cities due to population growth and the rapid development of the economy and industry. This leads to the proliferating need to monitor urban air quality to avoid personal exposure and to make savvy decisions on managing the environment. In the last decades, the Internet of Things (IoT) is increasingly being applied to environmental challenges, including air quality monitoring and visualization. In this thesis, we present CAVisAP, a context-aware system for outdoor air pollution visualization with IoT platforms. The system aims to provide context-aware visualization of three air pollutants such as nitrogen dioxide (NO2), ozone (O3) and particulate matter (PM2.5) in Melbourne, Australia and Skellefteå, Sweden. In addition to the primary context as location and time, CAVisAP takes into account users’ pollutant sensitivity levels and colour vision impairments to provide personalized pollution maps and pollution-based route planning. Experiments are conducted to validate the system and results are discussed.

    Authors: Hatara, Ella;

    The goal of this Master’s thesis is to respond to the sustainability challenges of the current fashion industry with two emerging themes, the circular economy and digitalization. The aim of the work was to research the current status of the digitalization of the Finnish fashion industry, the opportunities provided by utilization of digital tools with the contribution to circular economy, and the possible challenges related to them, based on a literature review and company examples. Due to low level of digitalization in the Finnish fashion industry, solutions for the life cycle stages of design, manufacturing, retail, and extended use phase have been sought with the help of examples from literature. According to circular economy principles, clothing should be designed to last both physically and aesthetically, minimizing raw material use. Digitally aided tools and data can be used in designing, which enables the consideration of the whole life cycle already in designing stage. The Internet of Things (IoT), Blockchain and other technologies, which create a digital twin of manufactured products, enables tracking clothes in retail and possibly even in recycling. Supply chain and production transparency and other relevant product-related information can be easily made accessible to consumers with tags that can be read through mobile devices. Companies and third-party services offer solutions to extend the lifespan of products, such as repair services and trading of used clothing. The resource requirements of digital technologies and tools can become a challenge. However, the low level of digitization in the fashion industry can be seen as Finland's advantage, as it enables the design of a seamless digital system without path dependencies. Tämän diplomityön tavoitteena on vastata nykyisen muotiteollisuuden kestävyyshaasteisiin kahdella keskeisellä nousevalla teemalla, kiertotaloudella ja digitalisaatiolla. Työn tavoitteena oli kirjallisuuskatsauksen ja yritysesimerkkien avulla selvittää Suomen muotiteollisuuden digitalisoitumisen nykytila, digitaalisten työkalujen tuomat mahdollisuudet ja kontribuutio kiertotalouteen, sekä mahdolliset haasteet niihin liittyen. Suomen muotiteollisuuden digitalisaation alhaiseen lähtötasoon on etsitty kirjallisuuden esimerkkien avulla ratkaisuja suunnittelun, tuotannon, myynnin ja käyttöiän pidentämisen elinkaarivaiheisiin. Kiertotalousperiaatteiden mukaisesti vaate tulee suunnitella kestämään aikaa niin fyysisesti kuin esteettisesti käyttäen mahdollisimman vähän raaka-aineita. Suunnittelussa voidaan hyödyntää digitaliavusteisia työkaluja ja dataa, jonka avulla koko elinkaari voidaan huomioida jo suunnitteluvaiheessa. Esineiden internet, lohkoketjut ja muut tuotannon teknologiat, jotka luovat digitaalisen version tuotteista, mahdollistavat vaatteiden seurannan myynnissä ja mahdollisesti jopa kierrätykseen asti. Toimitusketjun ja tuotannon läpinäkyvyys ja muu olennainen tuotteeseen liittyvä tieto voidaan tuoda helposti kuluttajien ulottuville mobiililaitteilla luettavien merkkien kautta. Tuotteiden käyttöiän pidentämiseksi, kuten korjauspalveluihin ja käytettyjen vaatteiden myyntiin ratkaisuja tarjoaa yritykset ja kolmannen osapuolen palvelut. Digitaalisten teknologioiden ja työkalujen resurssivaatimukset voivat osoittautua haasteeksi. Alhainen digitalisaation taso muotiteollisuudessa voidaan kuitenkin nähdä Suomen etuna, sillä se mahdollistaa saumattoman digitaalisen systeemin suunnittelun ilman polkuriippuvuutta.

    Authors: Mazurovskiy, Mikhail;

    The goal of this research is to specify requirements and create the high-view architecture of the Internet of Things system applied in greenhouse farming. The research was conducted based on the Middle East pharmaceutical company producing medicines made of cannabis. Four direct users of the system representing three main user groups were interviewed on the requirements elicitation stage. The collected requirements were specified separately according to their types. The level of detail of specified requirements enabled the creation of several architectural views. The developed architecture is based on a wireless sensor network, wired actuators network, and cloud-based IoT platform. The main elements used in the solution are devices provided by Libelium and cloud-based services offered by Amazon Web Services. The specified requirements and developed architecture were verified and validated by representatives of the pharmaceutical company and third-party IoT expert.

    Authors: Leinonen, Jari;

    This research investigates whether the weather balloon observation system can be made environmentally friendly. Through literature and patent search, combined with theory of inventive problem solving (TRIZ) methods, alternative materials and operations to the current system model are analyzed. Focusing on solutions applicable to the target environment, goal and budget, changes to the current policies are proposed. Furthermore, the findings are tested through two field experiments, with the objective of providing empirical data to the study as well as demonstrating proof-of-concept systems, as alternatives to the current one. By focusing on key features, this research seeks to gain a holistic view of the current and future operating models, consequently enabling the management level of relevant organizations to consider the proposed changes with all the necessary information at hand. These changes include (but not limited to) improving the current tracking method to allow easier retrieval of launched radiosondes, a biodegradable shell structure, color changes, a network receiver system based on existing field equipment, an open access database, and landing coordinate prediction and reporting model for the public. This research contributes not only to the available literature but also to the operational models, by suggesting more environmentally friendly ways of conducting high-altitude weather observations through radiosonde technology. Tämä tutkimus pyrkii selvittämään, voidaanko säähavaintopallojärjestelmä tehdä ympäristöystävälliseksi. Kirjallisuuden ja patenttihaun avulla, yhdistettynä keksinnöllisten ongelmanratkaisumenetelmien (TRIZ) teoriaan, analysoidaan vaihtoehtoisia materiaaleja ja toimintoja nykyiselle järjestelmämallille. Kohdeympäristöön, tavoitteeseen ja budjettiin keskittyvien ratkaisujen kautta voidaan nykyisiin käytäntöihin ehdottaa muutoksia. Lisäksi löydöksiä testataan kahdella kenttäkokeella, joiden tavoitteena on tuottaa tutkimukseen empiiristä tietoa sekä esitellä konseptit vaihtoehtoina nykyiselle järjestelmälle. Keskittymällä järjestelmien keskeisimpiin piirteisiin tämä tutkimus pyrkii luomaan kokonaisvaltaisen kuvan nykyisistä ja tulevista toimintamalleista, jolloin asianosaisten organisaatioiden johto saa kaiken tarvittavan tiedon ehdotettuja muutoksia käsitellessään. Näihin muutoksiin lukeutuvat muun muassa nykyisen seurantamenetelmän parantaminen lähetettyjen radiosondien jäljittämisen ja palauttamisen helpottamiseksi, biohajoava kuorirakenne, värimuutokset, olemassa oleviin kenttälaitteisiin perustuva vastaanotinverkko, avoimen pääsyn tietokanta sekä julkinen laskeutumiskoordinaattien ennustus- ja raportointimalli. Tämä tutkimus tukee aihealueesta saatavilla olevaa kirjallisuutta sekä myös toimintamalleja ehdottamalla ympäristöystävällisempiä tapoja suorittaa ilmakehän radiosonditekniikkaan perustuvia säähavaintoja.

    Authors: Ghoreishi, Malahat;

    The digital transformation and circular economy (CE) are two megatrends that have been discussed not only among practitioners and policy makers, but also as an interesting topic of research in the scientific world. While CE aims to transform the world economy model to a more sustainable and eco-friendlier version, digital technologies (DTs) are revolutionizing our everyday lives by offering innovative connected solutions. Implementing CE strategies offers considerable value by decoupling our production and consumption system from the linear model of ‘take-make-use-dispose’. However, applying CE principles requires a radical change in the way companies create and deliver value to their customers. Companies face challenges in aligning CE principles to their current system to offer service-oriented models instead of physical products. This raises the role of DTs as enablers of CE. In this sense, AI has been identified as one of the key DTs that can enhance circularity through advanced analytics capabilities. Utilising AI enables resource and energy efficiency that can help companies in making more resourceful decision-making. However, research on the effective utilisation of AI in circular value creation has been very limited and companies struggle to understand how AI can change their value creation model based on CE strategies. Addressing this gap, it is essential to develop the understanding of potential of AI in circular value creation. This thesis employs a mixed methods approach to answer the main research question: “How can AI enhance circular value creation for companies and related business models?”, starting with a conceptual approach to improve the concept of value creation in CE and reveal the role of AI in the ReSOLVE framework. This is followed by empirical investigations through qualitative studies on product design and business model (BM) aspects of circular value creation. Since qualitative studies of this dissertation emphasise the role of data in digitally enabled CE, a literature review was conducted to identify the aspects and value of data in AI-enabled BMs, following by an empirical examination of the conceptual model by the last study. The results contribute and add new knowledge to the field of AI and value creation in CE by providing detailed information on how AI can enhance resource and energy efficiency when applied in circular solutions. The findings demonstrate that AI can enhance circularity by enabling data-driven BMs such as product-service systems and the sharing economy. In addition, the results highlight the value of data for example in product design and prototyping, and the entire lifecycle of products to innovate AI-enabled BMs. The thesis identifies that an innovative business ecosystem which is connected by different DTs can enhance circularity for all the actors and partners of ecosystem through sharing transparent data that circulates within the supply chain.

    Authors: Nousiainen, Jalo;

    The field of exoplanet research is one of the most rapidly expanding research fields in modern astrophysics. In recent decades, astronomers have found most exoplanets via indirect techniques such as the transit and radial velocity method. The direct imaging technique called high contrast imaging (HCI) enables new ways to expand our knowledge of these exoplanets and exoplanetary systems. However, direct imaging of exoplanets is challenging due to the high contrast ratio and small angular separation from the host star. Thus, HCI detections, so far, are mostly limited to a few dozen young and luminous giant exoplanets. The new generation of HCI instruments, under development, will push direct imaging into increasingly challenging areas, discovering and characterizing exoplanets dimmer and closer to their host start. The ultimate goal is direct imaging and characterization of potentially habitable exoplanets. On ground-based telescopes, HCI instruments are equipped with eXtreme Adaptive Optics (XAO) that correct the phase fluctuations caused by the atmosphere. With an optimized instrument design, the residuals left by XAO correction set the limitation of sensitivity; thus, minimizing the XAO residuals is a crucial objective for ground-based HCI. Further, most habitable exoplanets are located at small angular separations from their host stars, where current XAO control algorithms leave strong residuals of stellar light that could be suppressed with more advanced algorithms. This thesis explores novel data-driven control methods for XAO control that cope with crucial limitations of traditional control laws, such as temporal delay and calibration errors. Improvement in these potentially reduces the residual flux of stellar light in the coronagraphic point spread function and thus enables fainter observations closer to the host star. We show that model-based RL is a promising XAO control approach that produces consistent results in numeric simulations and lab setups. The proposed methods suppress the temporal error, and photon noise compensates for misregistration and optical gain. It can also adapt to changing wind conditions in time scales of several seconds. Moreover, model-based RL manages the extreme time constraint of XAO control and, if well formulated, scales to ELT scale XAO.

    Authors: Gubanov, Aleksandr;

    Smart grasping means that a robot can automatically decide which object and how an object can be grasped. Firstly, a neural network should find the objects and get a 2D bounding box. The convolution neural network is used for processing the frames to detect the objects. Secondly, a proposed approach should support the robot to understand where it is possible to grasp the object. The decision should be done independently and autonomously such that reliable grasping becomes possible. In the experiment there are only a limited set of known objects. The quick addition of new objects is possible since an automatic process for extracting new objects from video was developed. The result of the thesis provides an automated system which connects the recognition system and the robot.

    The Hazardous Analysis and Critical Control Points (HACCP) process is an essential process in many fields, such as, the food processing field. In this process, a pen and paper have generally been used for documentation but some of the operators in this field have started using a digital solution for it. The main purpose of this master’s thesis is to add value to the HACCP process by integrating the documented data from the case company’s application to a client’s ERP system. As the results of this research, a software integration was developed for this data synchronization and the potential benefits of it and the digitalization of HACCP were researched. In the qualitative research, it was found out that the benefits of the digitalization of HACCP process correlate quite well with the typical benefits of process digitalization. Elintarvikkeiden omavalvonta on oleellinen osa monien eri alojen, esimerkkinä ruoan käsittely alan, arkipäiväisissä toiminnoissa. Monesti tähän prosessiin käytetään edelleen kynää ja paperia, mutta osa prosessia suorittavista toimijoista on siirtynyt digitaalisiin ratkaisuihin. Tämän diplomityön päätarkoitus on lisätä arvoa omavalvontaprosessiin synkronoimalla prosessin suorituksesta kerätyt tiedot (esimerkiksi mittausdata) prosessin suorittaja yrityksen toiminnanohjausjärjestelmään. Tuloksena luotiin ohjelmistointegraatio tapausyrityksen sovelluksen sekä asiakkaan toiminnanohjausjärjestelmän välillä sekä kartoitettiin sen, ja omavalvonnan digitalisoinnin hyötyjä. Laadullisessa tutkimuksessa havaitut hyödyt korreloivat osittain tyypillisten digitalisaatiosta saatavien hyötyjen kanssa.
