To enhance power output and reduce cost for practical application of microbial fuel cell (MFC), extensive experiments have done to study performance optimization of lab-made mediator-less MFC. Saccharomyces cerevisiae was first tamed to investigate electrical adaptability as electricigens during device operation. By analyzing open circuit voltage using anodes with different materials, iron anode was proved to be the most suitable material for its highly electrochemical activity and bargain price. The results of experiment also proved that the performance of MFC could be reinforced through increasing roughness of anodes. Furthermore, electrical adaptability of electricigens would be enhanced after taming was confirmed.

C Programming learning is a hard task. On one hand, complex concepts and principles in C programming is tedious formany novices. On the other hand, even when students know about the syntax detail, they fell still confused on how to construct a real application. To solve the problems, we presented the “student-centered” environment to facilitate programmers' knowledge and ability construction.

To meet the transmission security requirements of CNC systems, a message safety communication model, adopting two kinds of fault tolerance algorithms based on CNC dual ring bus, was presented. The safety communication mechanism and algorithms were deeply researched, and the structure of safety message in CNC dual ring bus was proposed. And then mathematic methods were adopted to analyze the performance of the new mechanism. The results proved that our fault-tolerant safety communication model can offer high available and high effective communication support for reliable data service on Fieldbus.

In this paper we present a method for disparity map computing and its correspondent high parallel hardware accelerator. Our solution considers a two step processing algorithm. First, we compute a one-dimensional biased sum of absolute differences, and later a spurious removal technique is performed to eliminate wrong estimations. The hardware accelerator introduces a memory organization, an address generation scheme and data-path units that have scalable features for several resolutions, frame rates, silicon use, and power consumption instantiations. We have implemented a five stage pipelined organization that operates at 174.5 MHz over an VIRTEX II PRO 2vp30fg676-7 FPGA device, carries out an equivalent of 9.074 GOPS and processes 142 frames per second of Common Intermediate Format (CIF).

In today's hi-tech and hi-precision world, robot finds its application in many areas to carryout operations that are either routine, highly complex and critical, hazardous or of high-precision nature. Robots when networked offer many benefits such as increased maneuverability and efficiency. The goal is to define a model-based development process for large sensor-actuator networks with a focus on wireless communication. This paper makes a study on the present developmental status and details the design features of Autonomous Self Organizing Embedded Sensor Networks for Process Monitoring. It is intended to use this work as basis for future research work in the area of modular production systems.

Iterative Learning Control (ILC) is now well established for linear and nonlinear dynamics in terms of both the underlying theory and experimental application. This approach is specifically targeted at applications where the same operation is repeated over a finite duration with resetting between successive executions. Each execution is known as a trial and the novel principle behind ILC is to suitably use information from previous trials in the selection of the current trial input with the objective of sequentially improving performance from trial-to-trial. In this paper, new computationally very efficient results on the extension of the ILC approach to the class of 2D systems that arise from certain methods of discretization of partial differential equations resulting in the need to use a spatio-temporal setting for analysis. The resulting control laws can be computed using Linear Matrix Inequalities (LMIs). An illustrative example is also given and areas for further research discussed.

Recently, application in embedded systems has increasingly become complex. This requires having tools to prevent or detect memory corruption errors during the software development process. Unfortunately, most of embedded processors lack to be equipped a MMU (Memory Management Units), one of hardware components supporting memory protection mechanism in general purpose computer system, because MMU-based memory protection methods cause embedded system incurred hardware cost and performance penalty. In this paper, an off-chip model is proposed to detect violated memory accesses at run-time without incurring hardware cost. It can efficiently detect errors for RTOS-based applications in cases of stack overflow, reading/writing to code/data segments of the other tasks or violated memory access to OS kernel. The hardware component based on FPGA is also built by hooking on memory system bus to monitor memory accesses. Once error detection phase is completed, the hardware prototype can be detached from the system. Some testbeds are used for this model and give good results.

In this paper, a formalism to encode patterns of events which occurrences must be monitored by a context-aware system is introduced. The Situation Definition Language is a tool used to specify relationships among sensory data in a distributed system, without posing any assumption on how data are acquired. The language capabilities are discussed with respect to an Ubiquitous Robotics scenario, where several robots cooperate with smart environments to perform given tasks.

The challenge to effectively and accurately determine pure partial discharge (PD) signals from the large amount of noise still remains. In this study, individual PD pulses were filtered, extracted and analyzed using digital signal processing techniques and data mining methods. The shape or distribution of the spectral frequency domain could be correlated with different PD signals. Feature extraction was explored using K-means clustering to categorize the similarities. A hard threshold method was applied to the time domain in which the critical PD pulses could be identified based on extracted features. A pre-determined threshold value was set and PD occurrences could be found and classified for fault diagnosis.
