Integrating a large number of embedded memories in System-on-Chips (SoC's) occupies up to more than 70% of the die size, thus requiring Built-In Self-Test (BIST) with the smallest possible area overhead. This paper analyzes MATS++(6N), March C-(10N), March SR(14N), and March CL(12N) test algorithms and shows that they cannot detect either Write Disturb Faults (WDFs) or Deceptive Read Destructive Faults (DRDFs) or both. Therefore to improve fault detection, an automation program is developed based on sequence operation (SQ) generation rules. However after solving the undetected fault, the outcome in term of its detection result of Static Double Cell Faults using the specified test algorithm especially Transition Coupling Faults (CFtrs), Write Destructive Coupling Faults (CFwds), Read Destructive Coupling Faults (CFrds) and Deceptive Read Destructive Faults (CFdrds) are observed. © 2012 IEEE.

International Journal of Advancements in Computing technology 2012年第20期4卷 625-632页

Frequent pattern mining on uncertain dataset takes into consideration of item's existing probability, but does discriminate items by their different importance. To address this issue, we propose a new mining model called High Expected Weight Itemsets Mining (or weighted frequent pattern mining) on uncertain dataset based on the concept of expected weight. We also propose a corresponding algorithm called HEWI-Mine to mine high expected weight itemsets from uncertain dataset using a pattern- growth approach. We perform some testing mining on multiple datasets, and observe different mining results produced. Because items in real-world transaction database do contain different weight properties, such as price or profit, this model may contribute to more precise analysis on business applications involving frequent pattern mining.

This paper presents the interference between Fixed Satellite Service (FSS) and Wireless Access Service (WAS) in the C-band for eastern Sudan environment. We analyzed the interference between FSS and WAS Eastern Sudan Environment and calculate the exclusion distances for the desired stations to ensure that the interference level does not exceed a certain level. Moreover, we calculate the total attenuations that may face these stations. Simulation is conducted by using ITU Spectrum Management System for Developing Countries (SMS4DC) software with reference to ITU recommendations to estimate the optimum location for FSS ground station without causing harmful interference to WAS stations. Our calculated simulation results gave an optimal interference exclusion zone when compared with ITU recommendation. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.

In context of cognitive radio, local sensing is not fitting the requirements for reliable detection of PUs due to its limitation in fading environment. Therefore, cooperative sensing is introduced as the key to reducing the probability of interference to legacy systems. However, cooperative gains are based on validity/reliability of sensing, control channel, and the network's cooperation protocol. Doubt on the subject of noise and interference imposes essential limits the sensitivity of cooperative sensing method. This inspires the strong need for advanced sensing and recognized it to be a distributed cooperative method. Here, we review the distributed detection concept and framework. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.

A high-density non-equilibrium atmospheric pressure plasma (NEAPP) applied for inactivating fungal spores of P. digitatum is introduced as an environmentally safe and rapid-inactivation method. The contributions of ozone, ultra violet (UV) radiation and ground-state atomic oxygen in the NEAPP on the inactivation of the spores are evaluated using colony count method. The absolute densities of ozone were measured by using ultraviolet absorption spectroscopy. The ozone density increased from 2 to 8 ppm with an increase in the distance from the plasma source, while the inactivation rate decreased. The inactivation rate of plasma was evaluated to be thousand times higher than that of an ozone generator using the integrated number density of ozone. In addition, it was clarified that the contribution of UV radiation to inactivation was not dominant for P. digitatum inactivation by NEAPP by filtering the active species using quartz plate. From these results, we can speculate that the inactivation efficiency of reactive oxygen species (ROS) will be larger than those of others. In order to investigate the effect of ground-state atomic oxygen as one of ROS, the inactivation of P. digitatum spores using an oxygen radical source that employs a high-density atmospheric-pressure O2/Ar plasma. The absolute O density was measured to be 1.4×1014 and 1.5×1015 cm-3 using vacuum ultra violet absorption spectroscopy (VUVAS) using a microdischarge hollow cathode lamp. The behaviors of the O densities as a function of O2/(Ar+O2) mixture flow rate ratio correspond to that of the inactivation rate. This result indicates that ground-state atomic oxygen is concluded to be the dominant species that causes inactivation. © 2012 Materials Research Society.

The Australian government is aiming to ensure that by 2020, 20% of Australia's electricity supply is generated from renewable sources. Consequently, this will drive large changes and have direct effects on the behavior and investment in Australia's market environment especially transmission use of system (TUoS) charges scheme. This paper is intended to explore the TUoS charges in the Australian national electricity market (NEM) to the development of renewable generation. There are three issues that are focused in this paper: 1) the transmission configurations for connecting the renewable generation to the existing grid;2) the existing Australian NEM TUoS charges;and 3) the Australian energy market operator (AEMO) policy on the allocation of the cost of providing shared transmission services to different parties for new and existing terminal stations. The 59-bus system of the South East Australian power system is used for the case study in order to verify the concepts and determine the efficient and economical way to connect a new renewable generation to the existing grid. © 2012 Institut Teknologi Sepulul.

In ship angular deformation measurement, Kalman filter used to estimate the deformation angle requires accurate dynamic flexure parameters. Traditionally, these dynamic flexure parameters are empirically set according to previous experience or determined from previously collected experimental data. Inevitably, the Kalman filter will perform poorly when the current application environment is differ with those used in the filter design. To overcome this problem, we propose an alternative online approach to estimate the dynamic flexure parameters based on the attitude difference measured by two laser gyro units. Specifically, the Tufts-Kumaresan (T-K) method is introduced to solve the unknown parameters of the dynamic flexure model from the computed attitude difference. Simulation results show that the proposed method can estimate the dynamic flexure parameters in real-time with a high degree of accuracy even in serious noise polluted conditions. A further advantage of the proposed approach is that it does not require a priori knowledge of the dynamic flexure characteristics. © 2012 IEEE.

In this paper, we have developed a low-cost sleep monitoring system for patient based on polysomnography which will be useful for patient communication with healthcare personals and/or relatives. In particular, we have presented the sensor pillow and bed sheet system that employs wireless networks based on low-cost ZigBee technology and a sensor array of force sensitive resistors (FSR) based on polymer thick film (PTF) device, for classifying and specifically verifying the respiration rate during sleep. This paper also proposes a simple motion model that explains the change of head and body pressure distribution. In addition, we can detect some physiological parameters during the sleep stages and wakefulness as well as record respiration rate as related to different physiological factors. The integration of this sensor system and wireless technology with computer software could make this healthcare monitoring system a commercial product valuable for point-of-care applications.
