Large displacement elastic joints have been widely used in rehabilitation exoskeleton, in this paper, a brief reminder of the application of large displacement elastic joints in exoskeleton robotic structures has been given. A new concept of rigid-compliant exoskeleton joint has been presented using four-bar compliant linkage for exoskeleton robot applications. The paper describes the method of designing...
This paper presents BlueAer, the first three-dimensional (3D) spatial-temporal fine particulate matter (PM2.5) monitoring system, which is designed to understand urban PM2.5 concentration distribution in a fine-grained level. For cost-efficient data collection, vast amount of 3D samples are collected by limited mobile carriers with built-in low-cost sensors. A 3D probabilistic concentration estimated...
In this paper, the on state quasi-saturation effect of high voltage SJ-VDMOS (Superjunction vertical double diffused MOSFET) which is formed using alternate process of boron implantation and n-epitaxial growth for several turns are investigated in detail. Transconductance of the device is studied by simply formula derivation of MOSFET. Velocity saturation in the JFET region is strongly influence the...
A novel MEMS Coulter counter for cell monitoring and detection is designed, fabricated and tested in this paper. Microfabrication is employed to form a multilayered sandwich structure consisting of an SU-8 microchannel on a glass substrate covered by a PDMS lid. The microchannel is further divided into a passive mixing region, a focusing region using negative dielectrophoretic forces and a measuring...
A full exploitation of the computational power available in a multi-core platform requires the software to be specified in terms of parallel execution flows. At the same time, modern embedded systems often consist of more parallel applications with timing requirements, concurrently executing on the same platform and sharing common resources. To prevent reciprocal interference among critical activities,...
The performance of the slow sand filter was examined using the landscape water with the experimental period of 46 days. The filter installed was similar to the traditional slow sand filter; expect that the top 5-cm sand was changed to the quartz sand. In this study, the variations of the turbidity, COD, BOD and TN were measured based on the filtration rate of 0.2m/h. Results showed that the average...
MANET is currently a hotspot in the wireless networks researching domain, and the routing protocol, which is as the core technology on network layers, is particularly important. Controlling node energy and increasing network lifetime are two keys to realize the transmission of efficient service for MANET. On the basis of analyzing classical MANET routing protocol, and combining with the idea of min...
The optimality of preemptive EDF scheduling with relation to the achievable system utilization is a clear advantage of this scheduling policy for single processor real-time systems. However, recent works suggested that the run-time behavior of EDF might be improved by limiting the preemption support only to particular time instants, dividing each task into a sequence of non-preemptive chunks of execution,...
The treatment performances of capillary infiltration system fed by municipal wastewater were investigated in this paper. The composite fillers were constructed in capillary infiltration system to reach the prospective treatment effects. Compared to the single filler, composite filler promoted the ventilating condition and improved the distribution situation. The higher treatment efficiencies of NH...
The study on degradation of domestic wastewater by the cinder infiltration columns was given in this paper. Four cinder infiltration columns were constructed, including two sorts of different filler altitudes and two sorts of different grain size fillers. According to the experiment, results indicated that the NH4+-N,COD,TP and SS removal efficiencies of all the four devices were excellent, the removal...
Intermediate Frequency (IF) filters find diverse practical applications in modern communication systems. This paper presents a novel technique for the design and discrete optimization of guaranteed BIBO stable digital IF filters over the canonical signed-digit (CSD) multiplier coefficient space. This technique consists of two separate stages. In the first stage, the bilinear-LDI Jaumann digital filter...
Control systems are typically designed assuming an ideal behavior of the computing infrastructure where controllers execute. In practice, however, in highly loaded computing systems consisting of multiple concurrent controllers, resource constraints may introduce delays and jitter in control loops that may degrade control performance significantly. Hence, taking resource constraints into account since...
Intermediate frequency (IF) filters find diverse practical applications in modern communication systems. This paper presents a novel technique for the design and optimization of digital IF filters. This technique consists of two separate stages. In the first stage, the bilinear-LDI lattice digital filter realization approach is exploited and applied to the design of an infinite- precision digital...
IF filters find diverse practical applications in modern communication systems. In the current analog IC fabrication technologies, IF filters are usually implemented as OTA-C filters. The design of OTA-C IF filters can be achieved by employing either the existing gradient-based optimization techniques or the conventional genetic algorithms (GAs). However, the latter approach may result in relatively...

High voltage pulsed power supply with high repetitive rate has found wide applications in industry, and military such as plasma source for ion implantation, microwave generator and high pulsed power laser. The conventional pulsed power supply is limited by gas switch with short lifetime and low repetitive frequency. In recent years Marx generator based on solid state switches...

Developing new methods to detect different electro-kinetic responses causing by biochemical differences was great scientific interest in the field of biophysics. An efficient method here was developed by using an electrokinetic system based on negative dielectrophoretic force (nDEP force) positioning and electrorotation (ROT). Electrokinetic responses of autotrophic and heterotrophic micro-algal cells...
