Planar linear motors, e.g. Sawyer motors, operate in an open-loop stepping manner. This mode of operation makes them i) susceptible to loss of steps, ii) unable to reject external disturbances, iii) unable to provide controlled forces, and iv) unable to provide high sti ness. These limitations, in turn, restrict their usefulness in a wide range of robotic applications. Suitable position sensing...

In this article, we aim at solving unconstrained gaze estimation problem using appearance-based approach. Unlike previous methods working in relatively constrained environment, we propose an approach that allows free head motion and significant user-sensor distances using RGBD sensor. Our paper presents the following contributions : (i) A direct estimation by inferring gaze information from RGB...

Hyperacuity is a general aspect of animal perception that exploits spatially overlapping sensory receptive fields to perceive at finer acuity than the sensor resolution. Following a recent demonstration of hyperacuity in robot touch, we present a detailed and systematic analysis of localization acuity for both a biomimetic fingertip and a region of tactile skin. We identify three key factors fo...

This paper describes the use of an analytical microfluidic sensor for accelerating chemo-repellent response and strong anti-bacterial 1-(Thien-2-yl)-3-(2, 6-difluoro phenyl) prop-2-en-1-one (1-TDPPO). The chemically-synthesized antimicrobial agent, which included prop-2-en-1-one and difluoro phenyl groups, was moving through an optically transparent polydimethylsiloxane (PDMS) microfluidic sens...

We present the design and fabrication of 2 μm wavelength range type-II InP-based lasers and photodetectors integrated on a silicon photonic circuit. “W”-shaped type-II InGaAs/GaAsSb quantum wells are used as active region in the laser and photodetector structures. In order to achieve high efficient mode coupling, a taper structure in both the III-V waveguide and silicon waveguide is used. An an...

We have investigated here the mechanism of dephosphorylation and activation of death-associated protein kinase (DAPK) and the role of lysosome in neuroblastoma cells (SH-SY5Y) treated with mitochondrial toxins, such as MPP(+) and rotenone. Mitochondrial respiratory chain inhibitors and uncouplers decreased mitochondrial membrane potential leading to DAPK dephosphorylation and activation. The cl...

Synthesis and characterization of four iridium(III)-octaethylporphyrins and a π-extended iridium(III)-benzoporphyrin are presented. Strong room-temperature phosphorescence was observed for all of the complexes with quantum yields of up to 30 %. Axial ligands were introduced to tune the photophysical properties and the solubility. Complexes bearing lipophilic ligands such as pyridine or N-(n-but...

An active sensing method for multisensor fusion systems with actuators is proposed. To realize active sensing with multiple sensors, i) where to position sensors, ii) how to associate data, and iii) how to fuse data should be determined. The authors propose a new method mainly concerning i). The method utilizes estimated errors of estimated values to determine optimal sensor locations where use...

This paper investigates the design of fault-tolerant TDMA-based data aggregation scheduling (DAS) protocols for wireless sensor networks (WSNs). DAS is a fundamental pattern of communication in wireless sensor networks where sensor nodes aggregate and relay data to a sink node. However, any such DAS protocol needs to be cognisant of the fact that crash failures can occur. We make the following ...
