Abstract:To improve the reading and writing speed of NAND flash array with multi-channel and multi-way, and to obtain the highest available bandwidth, an approach is presented in this paper. One mechanism of high efficiency bus accessing timing scheme based on interleaving is introduced into the approach. In pursuance of this timing, flash controllers are able to make every plane in the flash array to be active in parallel. Therefore the transmission ability to and from the bus can be greatly improved. Utilizing this approach, the accessing efficiency to the NAND flash array will be pushed to a very high level. According to the testing results, as opposed to normal flash bus timing scheme, the data reading efficiency can be increased by 68.5%%, and the data writing efficiency can be increased by 457%%, with the flash bus timing scheme presented in this paper being used. The conclusion can be drawn that the flash bus timing scheme presented in this paper is effective, and the reading and writing at very high speed to the NAND flash array can be realized.

Abstract:Estimating arithmetic is a design paradigm for DSP hardware. By allowing structurally incomplete arithmetic circuits to occasionally perform imprecise calculations, higher performance can be achieved in many different electronic systems. This paper presents a potential useful approach to implement tree multipliers by using estimating arithmetic. Experimental results show the applicability and effectiveness of the proposed approach.

Abstract:Resistive random access memory (RRAM) devices with Ni/AlOx/Pt-structure were manufactured by deposition of a solution-based aluminum oxide (AlOx) dielectric layer which was subsequently annealed at temperatures from 200 degrees C to 300 degrees C, in increments of 25 degrees C. The devices displayed typical bipolar resistive switching characteristics. Investigations were carried out on the effect of different annealing temperatures for associated RRAM devices to show that performance was correlated with changes of hydroxyl group concentration in the AlOx thin films. The annealing temperature of 250 degrees C was found to be optimal for the dielectric layer, exhibiting superior performance of the RRAM devices with the lowest operation voltage (<1.5 V), the highest ON/OFF ratio (>10(4)), the narrowest resistance distribution, the longest retention time (>10(4) s) and the most endurance cycles (>150).

Abstract:Renewable energy sources such as photovoltaic (PV), wind, tidal, and ocean waves have increasingly penetrated the global production of energy. Energy Internet has been widely regarded as one of the promising solutions for the serious energy crisis and environmental pollution problem. Unlike the conventional centralized power generation structure, energy Internet widely utilizes different types of distributed generations (DGs), which are located closer to the user and generate electric power within distributed networks. Modular energy storage devices (ESDs) such as batteries for electric vehicles can effectively complement the function of DGs through bidirectional plug-and-play power interfaces. Thus, energy Internet has the ability to minimize power loss, enhance power quality, and improve system reliability.

Abstract:Cancer plays a leading role in causing morbidity and mortality worldwide. Several treatments have been developed and practiced for fighting against cancer. Totally Implantable Venous Access Port Drug Supply (TIVAPDS) treatment is a new method utilizing Totally Implantable Venous Access Port (TIVAP) delivery method, which is one kind of Intrathecal Drug Delivery System (IDD) with lower side effects, to increase patient's quality of life. This paper reports our study aiming to evaluate the effectiveness of TIVAPDS treatment in order to make contributions to generalize this treatment in China. Our data samples come from The Second Affiliated Hospital of Suzhou University, a forerunner of TIVAPDS practices in China and with patients' agreement. The data statistics summary results and the relationships between each two identified attributes are analyzed. Based on the results, 2 predictive models utilizing C4.5 decision tree and logistic regression algorithms are adopted for prediction. The results are used as reference to assess individual treatment cases, so that the effectiveness of the treatment can be achieved and if possible, to improve the efficiency of TIVAPDS treatment.

Abstract:This paper presents a novel system for vision-based driving posture recognition. The driving posture dataset was prepared by a side-mounted camera looking at a driver's left profile. After pre-processing for illumination variations, eight action classes of constitutive components of the driving activities were segmented, including normal driving, operating a cell phone, eating and smoking. A global grid-based representation for the action sequence was emphasized, which featured two consecutive steps. Step 1 generates a motion descriptive shape based on a motion frequency image(MFI), and step 2 applies the pyramid histogram of oriented gradients (PHOG) for more discriminating characterization. A three level hierarchal classification system is designed to overcome the difficulties of some overlapping classes. Four commonly applied classifiers, including k-nearest neighbor(KNN), random forest (RF), support vector machine(SVM) and multiple layer perceptron (MLP), are evaluated in each level. The overall classification accuracy is over 87.2%% for the eight classes of driving actions by the proposed classification system.

Abstract:This paper is an attempt to explore new ways for allowing interaction with mobile devices, such as smartphones and tablets. Mobile devices have become very popular in a relatively short time. Their popularity is mainly due to the portability and until very recently their ease-of-interaction through the touch-enabled screen when compared to older devices. Their portability comes with a trade-off: the small screen through which users can interact with their content. The small size screen can limit significantly the amount of content they can interact with, and also the manner in which this interaction is carried out. In this research, we explore the ways of extending the interaction space of these devices. We assess if, how well, and what mechanisms are possible for enabling users to interact with content located off the screen. In this paper, we report our approach and some early results of experiments we have conducted.

Abstract:Microgrid is an intelligent power system wh ich contains distributed generations, energy storages, local loads, monitoring and protecting units to realize autonomous control, protect and manage functions. It's regarded as the trend for the future power system since it satisfies the rapidly-developing electrical power demand and reduces environmental concerns. Considering different operation modes of Microgrid such as grid-connected and stand-alone, the control strategies need be automatically adjusted with support from Grid, battery or Fuel Cells. In this paper, a Microgrid is buHt and simulated in PSCAD, including PV, wind power, Fuel Cell, lead acid battery, and microturbine. Both component and system level models are verified tor different scenarios with appropriate control strategies. Main results are illustrated in order to show the efTectiveness of the control strategy tor different modes.

Abstract:The emerging Internet of Things (IoT) paradigm offers great promise for creating a global Internetbased architecture connecting humans, autonomous mobile devices, sensor networks, medical devices, and cloud computing to provide context-Aware solutions to public health whenever and wherever healthcare services are demanded. Two of the main critical areas of significance in such Healthcare IoT (HIoT) are Inhouse healthcare management for elderly people and healthcare provision in remote areas where hospital facilities do not exist. From software engineering principles for constructing a trustworthy HIoT, it is essential that the "things" in the system are dependable and reusable and the design remains extendable. This in turn will maximize the quality of service and minimize the cost of service provisioning. Motivated by this vision, this paper investigates the notion of Healthcare Design Pattern(HDP) and explains how the HDPs can be the building blocks for cyber-enabled healthcare solutions in HIoT. Three specific examples of HDPs for In-house healthcare solutions are described.
