    Flight range and time, as well as autonomous flights in complex environments, are two challenges preventing quadcopters from being more widely used in the industry. This thesis reduces the effect of these two problems via several motion planning methods.This thesis is composed of three parts. In the first part, two methods are proposed to improve the flight time (endurance) and distance (range) of quadcopters. The first method does so by finding the optimal flight speed using extremum seeking control. The second method extends the first method by finding the optimal flight sideslip as well as speed, and adds a step size adapter to the extremum seeking controller to improve its convergence speed. Both methods do not require the power consumption modeling of the quadcopters and can thus adapt to changing payloads and disturbances.In the next part, we focus on the problem of fast collision avoidance flight in cluttered environments. First, we propose a computationally efficient memoryless planner for fast outdoor flights, using a depth camera for sensing obstacles and using the visual inertial odometry (VIO) for state estimation. Since the VIO may function poorly in areas with very few visual features or when the flight is overly aggressive. We then take the state estimation quality of the VIO into account during the trajectory planning. This perception-aware planner is able to guide the vehicle to areas with more VIO features and avoid overly aggressive trajectories. It improves the VIO's accuracy and reduces its failure rate, while only slightly reducing the flight speed.Finally, an inertial navigation motion planning strategy is introduced. This state estimation method only requires the inertial measurement unit (IMU) and can be used as a backup when other methods fail. By breaking a long trajectory into multiple short "hopping trajectories'' and introducing zero velocity updates when the vehicle is stationary on the ground, the state estimation variance can be drastically reduced and can be used in closed-loop control of quadcopters.

    Agriculture plays an important role in producing food supply for survival. The agriculture practice is performed by multiple factors such as soil type, fertilisers, plant samplings, irrigation practice, etc. On these factors on which agriculture depends, irrigation is one of the major factors for the better yield of crops, just like any other factor. Therefore, efficient irrigation practice has to be performed to increase cultivation production and preserve available water resources for optimal usage. Traditional methods of irrigation practice are well suited for situations with surplus water resources but not very efficient when it comes to scarce places. So, we propose a new IoT-driven root zone injection method of irrigation which is estimated to perform required irrigation practices in places of high water scarcity. This method is performed with the help of machine learning, IoT devices, wireless neural networking of sensors, and root zone injection equipment for automation. The mechanism starts with collecting real-time data from the agricultural field for specified crop types by using a wireless neural network of sensors and forming the dataset. Once the dataset is formed, it will be processed and cleaned to feed into machine learning algorithms. The machine learning algorithm (here, it is linear regression) will make the required prediction for the water content needed for the irrigation process for that particular day. The dynamic estimation is made as the water content required will vary from the growing phases of plants where it is minimum at the initial phase, peak at middle and reduce or increase depending on the plant species at later phase of growth. This estimated water content is then delivered to the plants through the irrigation process, governed by the IoT devices, which have the procedures encoded for irrigation. ML prediction guides the IoT system on how much water to deliver to the plants. Finally, the injection setup of the root zone passes the water directly to the underground root zones. Thus, completely preventing evaporation wastage and accurate water content estimation and supply, achieving optimal irrigation practice.

    Introduction: The outbreak of COVID-19 led the world to a new era of digitalization, as the mandatory worldwide social isolation in the first quarter of the year 2020 changed the communication between people to happen mainly through digital platforms. It is to be expected that due to time and money-saving aspects, remote working and studying will continue after the worse days of the pandemic, and hours of digital device usage will also remain massive in the future. Purpose: This scoping review aimed to identify existing research results and possible information deficiencies in the existing studies and compare empirical evidence of how the outbreak of COVID-19 has impacted the use of digital devices and, thereby, digital eye strain in adults. Methods: This scoping review consisted of eight qualitative descriptive survey studies. The main literature search was conducted on the 21st of March 2022 from three different databases, PubMed, CINAHL, and Academic search premier, using key search terms ("computer vision syndrome" OR "digital eye strain") AND ("covid-19" OR "sars-cov-2"). Only studies regarding adults (age limit 18 years), available in full text and published in English, were included. Results: The reported average increase in screen time after the outbreak of COVID-19 ranged between 2.1h – 4.8h ± 2.8h, raising the total screen time to 8.65h ± 3,74h - 11.1h ± 4.5h. The prevalence of digital eye strain ranged between 66.6% to 94.3%. The increase in screen time was the most reported risk factor for DES. Young adults were found to be more symptomatic than relatively older people. Even though the prevalence of DES remained quite the same compared to pre-covid time, the frequency and intensity of symptoms became more severe while total screen time increased in all age groups. Additionally, the median DES scores were higher for those whose screen time jumped more during the pandemic. The most common symptoms were headache, dryness of the eyes, eye strain, and eye fatigue. Conclusions: The results give an alarming sign of how this new era of digitalization may lead to epidemic worsening or even chronic state of digital eye strain in the future, especially among young adults, all students, and remote workers, if total screen time remains as high as reported in recent studies, adequate breaks are not taken care of, and proper ergonomics are neglected.

    Aineistossa on kartoitettu suomalaisten digitaalisten laitteiden, sosiaalisen median ja verkkopalveluiden käyttöä. Kysymykset käsittelivät lisäksi yhteiskunnallista arvomaailmaa ja osallistumista sekä sosiaalisia suhteita ja hyvinvointia. Median käyttöä käsittelevässä osiossa kysyttiin, kuinka usein vastaajat muun muassa käyttävät internetiä, kuuntelevat radio-ohjelmia tai kirjoittavat keskustelufoorumeille. Vastaajat kertoivat, käyttävätkö he erilaisia älylaitteita. Internetin käyttötaitoja kartoitettiin erilaisin väittämin, kuten osaako tutkittava tyhjentää selaimen sivuhistorian. Lisäksi kysyttiin, miten tärkeäksi internet koetaan esimerkiksi pankkiasioiden hoitamisessa tai yhteydenpidossa muihin ihmisiin. Vastaajat ottivat myös kantaa väittämiin internetlähteiden luotettavuudesta ja tiedon etsimisestä. Tutkittavilta kysyttiin, mihin tarkoituksiin he käyttävät sosiaalista mediaa, ja tietävätkö he millaista tietoa on sopivaa jakaa verkossa. Vastaajat kertoivat, miten he suhtautuvat sosiaalisessa mediassa mielipiteisiin, jotka eroavat heidän omistaan, ja millaista mielikuvaa itsestään he levittävät. Heiltä kysyttiin myös, mitä sosiaalisen median palveluita he käyttävät. Vastaajat kertoivat, aiheuttaako sosiaalinen media ulkonäköpaineita. Tämän jälkeen kartoitettiin erilaisia kansalaistoimia, joihin vastaajat olivat osallistuneet, sekä vastaajien puoluekantaa ja suhtautumista erilaisiin yhteiskunnallisiin asioihin, kuten maahanmuuton kasvuun tai maaseudun autioitumiseen. Vastaajat kertoivat, kuinka luotettavina he pitävät muun muassa eduskuntaa, poliittisia puolueita ja suuria kansainvälisiä yhtiöitä. Lopuksi kysyttiin vastaajien sosiaalisista suhteista ja yksinäisyydestä, onko heihin kohdistunut verkossa esimerkiksi seksuaalista häirintää, ja miten he kuvailisivat omaa taloudellista tilannettaan ja terveyttään. Taustatietoja aineistossa ovat vastaajan sukupuoli, syntymävuosi, maakunta, suuralue, parisuhdetilanne, kotitalouden henkilömäärä, koulutustaso, ammatti ja työnantajasektori sekä kotitalouden yhteenlasketut tulot. The survey charted the use of digital devices, social media, and online services in Finland. Main themes of the survey also included societal values, civic participation, social relationships, and well-being. Media use was investigated with questions on how often the respondents did certain things (e.g. use the internet, listen to radio programs or podcasts, write on discussion boards, use instant messaging applications). The respondents were also asked whether they used certain digital devices and services (e.g. smart phone, computer, broadband internet, smart watch) and how important these were for their everyday lives. The role of the internet in the respondents' everyday lives was explored by asking how important the internet was for them in terms of banking, booking doctor's appointments, purchasing products and services, and keeping in touch with others. The respondents' digital skills were charted by asking them, for example, whether they knew how to download and save files from the internet or clear their browser history. Additionally, views on the trustworthiness of internet sources and the ease of finding reliable information online were surveyed. The respondents were asked about the purposes for which they used social media, whether they knew what kind of information was appropriate to share on social media, and their membership in social media communities. Additionally, the respondents' use of different social media platforms and compulsive social media use were charted. Attitudes towards social media were examined with questions on, for example, whether the respondents were concerned about hate speech or fake news on social media, how they engaged with opinions that differed from their own on social media, and whether social media had made them feel pressure over their appearance. Civic participation was charted by asking the respondents whether in the last five years they had, for example, voted in parliamentary elections, taken part in a demonstration, donated money to charity or volunteered. Political party affiliation and the respondents' alignment on left-right and liberal-conservative political spectrums were also surveyed. Additionally, the respondents' views on various questions (e.g. the right to abortion, same-sex marriage, cuts to social security, dismantling the welfare state) and their trust in institutions (e.g. the government, the judicial system, politicians, the European parliament, news outlets) were investigated. The respondents' social relationships were examined with questions on how many friends they had on social media, how much they used social media to keep in touch with friends, how often they felt lonely, and how often they used social media to alleviate feelings of loneliness. Experiences of online harassment and bullying were also charted. The respondents were asked about their satisfaction with their body and appearance, and well-being was surveyed with statements on, for example, health, self-confidence, future expectations, and overall life satisfaction. Background information included the respondent's gender, year of birth , NUTS2 and NUTS3 regions of residence, marital status, household characteristics, level of education, occupation, sector of employment, and monthly household gross income.

    Flight range and time, as well as autonomous flights in complex environments, are two challenges preventing quadcopters from being more widely used in the industry. This thesis reduces the effect of these two problems via several motion planning methods.This thesis is composed of three parts. In the first part, two methods are proposed to improve the flight time (endurance) and distance (range) of quadcopters. The first method does so by finding the optimal flight speed using extremum seeking control. The second method extends the first method by finding the optimal flight sideslip as well as speed, and adds a step size adapter to the extremum seeking controller to improve its convergence speed. Both methods do not require the power consumption modeling of the quadcopters and can thus adapt to changing payloads and disturbances.In the next part, we focus on the problem of fast collision avoidance flight in cluttered environments. First, we propose a computationally efficient memoryless planner for fast outdoor flights, using a depth camera for sensing obstacles and using the visual inertial odometry (VIO) for state estimation.

Attitudes towards social media were examined with questions on, for example, whether the respondents were concerned about hate speech or fake news on social media, how they engaged with opinions that differed from their own on social media, and whether social media had made them feel pressure over their appearance. Civic participation was charted by asking the respondents whether in the last five years they had, for example, voted in parliamentary elections, taken part in a demonstration, donated money to charity or volunteered. Political party affiliation and the respondents' alignment on left-right and liberal-conservative political spectrums were also surveyed. Additionally, the respondents' views on various questions (e.g. the right to abortion, same-sex marriage, cuts to social security, dismantling the welfare state) and their trust in institutions (e.g. the government, the judicial system, politicians, the European parliament, news outlets) were investigated. The respondents' social relationships were examined with questions on how many friends they had on social media, how much they used social media to keep in touch with friends, how often they felt lonely, and how often they used social media to alleviate feelings of loneliness. Experiences of online harassment and bullying were also charted. The respondents were asked about their satisfaction with their body and appearance, and well-being was surveyed with statements on, for example, health, self-confidence, future expectations, and overall life satisfaction. Background information included the respondent's gender, year of birth , NUTS2 and NUTS3 regions of residence, marital status, household characteristics, level of education, occupation, sector of employment, and monthly household gross income.
