Motion measurement is a key function for patient diagnosis, therapy and rehabilitation in clinical disciplines ranging physiology, audiology, orthopaedics, neurophysiology. The equipment can be by video camera recording, machine vision systems and force plates. Motion analysis systems supported by multi-camera machine vision systems are an expensive solution for many applications. Force plates are...
Self-assembly by DNA tiles has been advocated as a possible technique for bottom-up manufacturing of scaffolds in the nanoscale region. However, self-assembly is severely affected by facet roughening errors. A particularly effective error tolerant method utilizes snake tile sets with a square block of even dimension (i.e. 2 k times 2 k) of tiles. Snake tile sets of odd dimension (i.e. (2 k - 1) x...
Reversible logic design is a well-known paradigm in digital computation. In this paper, quantum-dot cellular automata (QCA) is investigated for testable implementations of reversible logic in array systems. C-testability of a ID array is investigated for multiple cell faults. It has been shown that fault masking is possible in the presence of multiple faults [9]. A technique for achieving C-testability...
The aim of this paper is to determine if operating has an effect on a surgeon's muscular fatigue and hand tremor. Electromyography and tremor measurements were taken throughout a day of operating from the brachioradialis (BR) and mid deltoid (MD) muscles of six head and neck surgery consultants and two ear, nose, and throat (ENT) registrars. The percent change in mean frequency (MF) of their EMG signal...
In this study, a "dual detectors" method is proposed to overcome the limitation imposed by the speed-noise trade-off and improve the performance of a practical quantum key distribution (QKD) system based on realistic detectors. The "dual detectors" scheme can be employed to improve the performance of a Gaussian-modulated coherent states (GMCS) QKD system based on realistic homodyne...
As a possible technology for bottom-up manufacturing, DNA self-assembly requires tolerance to different errors. Among the methods for reducing the error rate, snake tile sets utilize a square block of even dimension of tiles (i.e., 2k ? 2k). In this paper, an odd-sized square block (i.e., (2k-1)?(2k-1)) is proposed as basis for snake tile sets. In comparison with all other tile sets, the proposed...
Desktop computing remains indispensable in scientific exploration, largely because it provides people with devices for human interaction and environments for interactive job execution. However, with today's rapidly growing data volume and task complexity, it is increasingly hard for individual workstations to meet the demands of interactive scientific data processing. The increasing cost of such interactive...
Reversible logic design is a well-known paradigm in digital computation. While an extensive literature exists on its mathematical characterization, little work has been reported on its possible technological basis. In this paper, a quantum-dot cellular automata (QCA) is investigated for testable implementations of reversible logic. Two new reversible gates (denoted as QCA1 and QCA2) are proposed....
A particularly difficult case in electromagnetic induction tomography (EMT) is to image internal structure at the centre of the object space when the material at the outer regions is conductive. This is because the outer material acts as an electromagnetic screen, which partially excludes the magnetic field from the interior space and hence reduces the sensitivity at the centre. In this paper, we...
For the first time, the locational marginal pricing (LMP) based market model is studied on a Chinese regional market. This paper reports upon preliminary results of applying LMP market design in North China Grid (NCG). Common key features of successful markets are discussed in reference to the existing LMP markets in the U.S. and other countries. As the pricing and dispatch framework of an LMP market,...

Parallel sequence-search tools are rising in popularity among computational biologists. With the rapid growth of sequence databases, database segmentation is the trend of the future for such search tools. While I/O currently is not a significant bottleneck for parallel sequence-search tools, future technologies including faster processors, customized computational hardware such as FPGAs, improved...
The power electronics building blocks (PEBB) concept has evolved into an alternative to conventional power converter design, and many industries have adopted this concept. This paper outlines the design process of a 33 kW PEBB, from power stage design and component selection to the design of the hardware manager board. The hardware manager encompasses the intelligence behind the PEBB, managing control...
Silicon carbide is a leading semiconductor for high power, high temperature electronics, yet SiC devices still face problems of electrical contact control and reproducibility. Recent work worldwide shows that point and extended defects in SiC as well as chemical reactions at metal-SiC interfaces can influence contact transport properties. Yet Schottky barrier and ohmic contact formation at the intimate...

A one-step-ahead adaptive controller for nonlinear systems using the back-propagation network is presented. At each point of time, the nonlinear relationship between the output and the latest control input of the system is replaced by its first-order approximation. In other words, the nonlinearity is considered to be linear time-varying at each sampling interval, and consequently, one-step-ahead adaptive...
