Everyone has a fundamental desire for sleep. By sleeping, humans can conserve energy and replenish their stamina to optimal levels. Lighting is one component that influences the quality of a person's sleep. One of them is a person who sleeps with the lights on, suffers from nyctophobia, has poor sleep quality, and may be responsible for several illnesses. This study aims to develop a smart lighting device that will aid in treating youngsters with nyctophobia to get used to sleeping with the lights off to improve their sleep quality. The case study methodology used in this study entails the development of a prototype. This method employs an oximeter as a heart rate detector and a sensor comparison as the measurement device. Arduino Uno circuit and heart rate sensor are the main devices in this research. At the same time, the NRF 24L01 is a communication medium between the two Arduino Uno boards. The experimental measurements in normal conditions indicate that the heart rate sensor was nearly the same as the value displayed by the oximeter. Similarly, after running for 1 minute, both devices produced almost identical results, with an average difference of 1 Beats Per Minute (BPM). According to experiments with a heart rate sensor, the switch-off condition can be activated if the heart rate hits 90 BPM. In this case, the light will switch off once the heart rate hits 70 BPM, which might be used for sleeping individuals. © 2022 IEEE.

Reconfigurable devices are expected to be utilized in the mission-critical fields such as space development, because a system update and a pseudo-repair can be achieved remotely by reconfiguration. However, conventional reconfigurable devices suffer from configuration memory upsets caused by radiation in space. This paper proposes an architecture of a fault-tolerant reconfigurable device based on island-style FPGA. The device consists of "autonomous-repair cells" which repairs these upsets autonomously and dynamically. To determine the architecture, we analyze four autonomous repair techniques of the cell experimentally. Then, optimal autonomous repair techniques are applied to both of programmable logics and cell-to-cell routing resources. Through evaluation, we show that proposed device achieves more than 10 years average lifetime against configuration upsets even in a severe situation such as a satellite orbit

SummaryIn this study, we demonstrated light shift detection in a running atomic clock using the multi-photodetection method. This method enables the observation of atomic resonances with different intensities using the intensity distribution of the laser beam. As it requires only two photodiodes to detect light shifts, it is easily applicable to miniature vapor-cell-based atomic clocks such as chip-scale atomic clocks and miniature atomic clocks.

Where IP cores to be mapped must be carefully solved for any given application in order to optimize different performance metrics in Network-on-Chip (NoC) design flow. The optimization of different performance metrics simultaneously may cause a negative effect on each other because of the strong correlation between these performance metrics. In this paper, we propose a multi-objective ant colony algorithm (MOACA) that maps IP cores onto mesh-based NoC architectures. This algorithm is an efficient way to find the pareto-optimal front which optimizes energy consumption and hotspot temperature of NoC. The algorithm has been implemented and evaluated for synthetic generated benchmarks. Experimental results confirm the efficiency, accuracy and scalability of the algorithm. © 2011 IEEE.

Statistical discovery of site inter-dependencies in sub-molecular hierarchical protein structuring

Background: Much progress has been made in understanding the 3D structure of proteins using methods such as NMR and X-ray crystallography. The resulting 3D structures are extremely informative, but do not always reveal which sites and residues within the structure are of special importance. Recently, there are indications that multiple-residue, sub-domain structural relationships within the larger 3D consensus structure of a protein can be inferred from the analysis of the multiple sequence alignment data of a protein family. These intra-dependent clusters of associated sites are used to indicate hierarchical inter-residue relationships within the 3D structure. To reveal the patterns of associations among individual amino acids or sub-domain components within the structure, we apply a k-modes attribute (aligned site) clustering algorithm to the ubiquitin and transthyretin families in order to discover associations among groups of sites within the multiple sequence alignment. We then observe what these associations imply within the 3D structure of these two protein families. Results: The k-modes site clustering algorithm we developed maximizes the intra-group interdependencies based on a normalized mutual information measure. The clusters formed correspond to sub-structural components or binding and interface locations. Applying this data-directed method to the ubiquitin and transthyretin protein family multiple sequence alignments as a test bed, we located numerous interesting associations of interdependent sites. These clusters were then arranged into cluster tree diagrams which revealed four structural sub-domains within the single domain structure of ubiquitin and a single large sub-domain within transthyretin associated with the interface among transthyretin monomers. In addition, several clusters of mutually interdependent sites were discovered for each protein family, each of which appear to play an important role in the molecular structure and/or function. Co

Describes a biped walking control system based on the reactive force interaction control at the foothold: 1) robust control of reactive force/torque interaction at the foothold based on Cartesian space motion controller: 2) posture control considering the physical constraints of the reactive force/torque at the foothold by quadratic programming. The proposed approach realizes robust biped locomotion because the environmental interaction is directly controlled. The control is applied to the 20 axes simulation model, and the stable biped locomotion is realized even if an unknown small slope exists. Stable attitude control is confirmed by 14-axis biped robot experiments.

Annual Conference of Industrial Electronics Society

This paper describes a walking pattern generation of a biped robot with parallel mechanism. By using the parallel mechanism, all actuators have been arranged on the upper part of the body. The biped robot, whose leg is applied to a parallel linked structure, can be composed of a lightweight leg. Furthermore, the load torque of an actuator can be distributed. Therefore, the biped robot with parallel mechanism is suitable for walking. Such a biped robot can be regarded as 3 masses, that is body and two feet. State variables of three masses are defined in inertial space and these are represented by a time polynomial equation. A walking pattern is expressed by larger order of polynomials rather than the order which decided according to boundary conditions. By representing this, the walking pattern with which an evaluation function is satisfied is generable. In this paper, the second power sum of contact force of the robot is evaluated into time polynomial equation. The proposed method is very high extendibility. These approach is that a robot can adapt itself to various environment.
