    Humans have multiple ways to adapt their arm dynamics to the task they have to perform. One way of doing this is through co-contraction of antagonist muscles. In telemanipulation this ability is easily lost due to time delays, quantization effects, bandwidth or hardware limitations. In this work a new concept for telemanipulation is presented. The end-point stiffness of a (simulated) telerobot is controlled via a variable impedance controller. The end effector stiffness scales with an estimate of the co-contraction around the elbow of the teleoperator. The telemanipulation concept was evaluated with ten subjects that performed two telemanipulation tasks in six different conditions. Three impedance levels: Low, high, and variable, and two delay settings. The first task was on positioning accuracy, the second task on impact minimization. We have shown that low and variable impedance performed significantly better on the force task than high impedance. We have also shown that high and variable impedance performed significantly better on the position task than low impedance. This shows that the human ability to control arm stiffness can effectively be transferred to a telemanipulated robot.

    The paper focuses on issues related to dialogue modelling that enables interaction between users and service systems, on topics that concern the experience and knowledge of people in the service industry. We discuss dialogue design that is based on the crowd-sourced data structured according to goal-directed ontological requirements, as well as architectural aspects and the human-centered companion view of IoT communication. Our ultimate aim is to create a framework for improving and reconstructing operations for service industries such as nursing, caregiving, and education, and for activities that promote health and create community through hobbies such as dance and music.

    Malnutrition is a condition where the body is deprived of important nutrients required to maintain healthy tissues and organ function. Maintaining the right balance in food intake is very important, especially in infants where tremendous growth occurs. Unlike adults, infants require someone's assistance in their food intake. In the modern world, where most of the infants are being sent to daycare, an automated food monitoring system helps in keeping track of their food intake. In this paper an automated food monitoring system with predictions to help a balanced meal is proposed. This sensor system consists of a piezo-based sensor board which can help in analyzing the weight of each meal and a smart phone camera to obtain nutrition facts of the ingredients.

    The passive microwave observations from geostationary earth orbit (GEO) are able to enhance the short-time forecasting of tropical cyclones (TCs) due to its ability to track and detect the internal structure of TCs. To assess the operational capabilities of the candidate GEO microwave instruments, the numerical simulations of GEO microwave observation for the three TC cases were carried out. This paper compares the abilities of 3 candidate passive microwave sensors, based on GEM/GOMAS, GeoSTAR and GIMS-II respectively, to observe the upwelling brightness temperatures of TCs at 50–57GHz band. The analysis is based on WRF model variables and radiative transfer mode DOTLRT.

    A detailed spatially explicit evapotranspiration (ET) mapping at daily basis is of substantial benefit for agricultural water management. An integrated multi-sensor approach that combines the benefits of the high spatial resolution of Landsat and the high temporal resolution of MODIS and geostationary satellites to provide daily field-scale ET estimates is evaluated over two different agricultural landscapes. The ET data fusion methodology described here can provide detailed information about daily and seasonal water use patterns. This information can be of utility for irrigation managers at the scale of individual fields as well as for regional monitoring of water use toward allocation and conservation efforts.

    Abstract The Agent-based Cooperating Smart Objects methodology (ACOSO-Meth) fully supports the systematic development of Internet of Things (IoT) systems from analysis to implementation by tackling their manifold requirements (e.g., self-management, distributed smartness, interoperability). At the same time, ACOSO-Meth allows the re-engineering of existing IoT systems, thus enhancing their maintainability, reusability and extensibility. In such direction, this paper (i) first presents the integration of the resource-oriented agent framework complying with the IETF Constrained RESTful Environment (CoRE) framework into ACOSO-Meth; then (ii) reports a case study to exemplify the re-engineering of a resource-constrained agent application through the ACOSO-Meth metamodel-driven approach.

    In this paper, we simulate a resonant clocking driver for low-power and low-voltage LSI. During the past decade, several highspeed LSI test chips operating in GHz range successfully demonstrated a variety of resonant clocking implementations, but few tests in low-frequency range have been reported. The authors report the operation of the low operating frequency resonant clock driver for IoT device through the SPICE simulation. From the simulation results, we found that the aspect ratio (W/L) of MOS in the final stage is the important geometrical factor that determines the clock waveform.

    This paper further explores bathymetric extraction techniques using overlapping orthoimages in shallow water areas through two-medium ray refraction and multispectral information inversion. In texture-rich areas, a ray refraction method using overlapping orthoimages is developed to calculate the depth information of the underwater features. In texture-less areas, the commonly-used multispectral inversion techniques are applied. The depth information from the ray refraction method acts as the references for the multispectral inversion techniques, therefore, an integrated approach of extracting the shallow bathymetry based on overlapping orthoimages is formed. The results from an aerial overlapping orthoimages experiment show that 0.5 m accuracy can be achieved in the study area. The proposed approach is the combination of two simple methods, and is easy to be implemented and flexible to use, giving that there are a large amount of existing overlapping multispectral orthoimages in water related areas, the proposed approach has the great potentials for the practical use.
