This paper analyzes the survey result on the information security requirement for smart grid. The survey was conducted via distributing questionnaires. Descriptive analysis has successfully ranked the information security consumer requirements with the compass of mean and standard deviation. Privacy concern becomes the most important element among the other fifteen requirements. Result showed that the philosophy category has the most powerful impact on consumer trust and satisfaction, because the philosophy and strategy of management with regard to information security is the perfect standard against which technology and other security mechanisms can be measured. This paper gives insight on a picture of smart grid system information security future direction. © 2012 IEEE.

Rehabilitation activities require continuous monitoring process in order to provide information of rehabilitation results to be analyzed by physical therapist. The purpose of monitoring is to help them to improve rehabilitation process. Moreover, a portable and simple home-based rehabilitation device can help patients to improve daily rehabilitation activity. Some previous studies regarding home-based rehabilitation process have shown improvement in promoting human movement recovery. But existing rehabilitation devices are expensive and need to be supervised by physical therapist, which are complicated to be used at home. Some devices (such as exoskeleton-type devices) are also not so efficient to be used at home due to large size and complex system. In this current work combination of sensors (flex sensor, force sensitive sensor and accelerometer) were assessed in order to be implemented as a multi-sensor unit for a portable arm rehabilitation device. Analog signal from the sensors will be conveyed to an Arduino microcontroller for data processing and logging. The results of rehabilitation activity can be used for further monitoring and analysis. An LCD display will show to the user the achievement of their exercise activity.

Optimal Control of an SIR Model with Delay in State and Control Variables

International Scholarly Research Notices 2013年第1期2013卷

作者： Mohamed Elhia Mostafa Rachik Elhabib Benlahmar Laboratory of Analysis Modeling and Simulation Department of Mathematics and Computer Science Faculty of Sciences Ben M’Sik Hassan II University Mohammedia BP 7955 Sidi Othman Casablanca Moroccounivh2m.ac.ma

We will investigate the optimal control strategy of an SIR epidemic model with time delay in state and control variables. We use a vaccination program to minimize the number of susceptible and infected individuals and to maximize the number of recovered individuals. Existence for the optimal control is established; Pontryagin’s maximum principle is used to characterize this optimal control, and the optimality system is solved by a discretization method based on the forward and backward difference approximations. The numerical simulation is carried out using data regarding the course of influenza A (H1N1) in Morocco. The obtained results confirm the performance of the optimization strategy.

simulation and modeling of turbulent flow, and of turbulent reacting flow in particular, involves solving for and analyzing time-dependent and spatially dense tensor quantities, such as turbulent stress tensors. The interactive visual exploration of these tensor quantities can effectively steer the computational modeling of combustion systems. In this chapter, we discuss the challenges in dense symmetric-tensor visualization applied to turbulent combustion calculation, and analyze the feasibility of using several established tensor visualization techniques in the context of exploring space-time relationships in computationally-simulated combustion tensor data. To tackle the pervasive problems of occlusion and clutter, we propose a solution combining techniques from information and scientific visualization. Specifically, the proposed solution combines a detailed 3D inspection view based on volume rendering with glyph-based representations—used as 2D probes—while leveraging interactive filtering and flow salience cues to clarify the structure of the tensor datasets. Side-by-side views of multiple timesteps facilitate the analysis of time-space relationships. The resulting prototype enables an analysis style based on the overview first, zoom and filter, then details on demand paradigm originally proposed in information visualization. The result is a visual analysis tool to be utilized in debugging, benchmarking, and verification of models and solutions in turbulent combustion. We demonstrate this analysis tool on three example configurations and report feedback from combustion researchers. © Springer-Verlag Berlin Heidelberg 2012.

We propose a novel disc-based data decomposition algorithm for N-body simulations and compare its performance against a cyclic decomposition algorithm. We implement the data decomposition algorithms towards the calculation of three-body interactions in the Stillinger-Weber potential for a system of water molecules. The performance is studied in terms of load balance behavior and speedup from the MPI implementations of the two algorithms. We are also currently working on a performance study of the disc-based decomposition algorithm on graphics processing units (GPUs).

A smart grid project necessitates consumer's affirmation to function, which indirectly requires their trust. This study takes account on consumer's consensus via questionnaire survey. First, importance of information security systems in the smart grid is abstracted. Then characters of functional requirements are identified, analyzed and discussed. Based on the proposed model, the identified information security requirements of smart grid are studied and summarized. From the descriptive ranking, consumer is longing of feeling secure while adopting the comprehensive and multilayered of the great smart grid. From the simple lattice ordering result, rule base social system category has the most powerful impact on consumer trust and satisfaction. But in the interlinking, there lays philosophy. This study advanced smart grid information security functionality by developing an innovative set of functional requirements target to enhance next-generation technologies and tools in the areas of transmission, distribution, energy storage, power electronics and cyber security. The smart grid that consumer perceived is user friendly, sense of security and; easy to understand and operate.

Since its fabrication in 2004 by A. Geim, K. Novoselov and colleagues at University of Manchester [1], graphene has been considered as a promising candidate material for future nanoelectronics applications. This is due to its high mobility and excellent thermal conductivity. Although graphene is a zero band gap semiconductor but by patterning it into graphene nanoribbons (GNR) (i.e. ribbons a few nanometers wide), nonzero band gap can be achieved. In order to use GNR in electronic devices, it is essential to study its mobility and the associated scattering mechanisms. As the technology develops, effects of extrinsic scattering mechanisms such as line edge roughness vanish while the intrinsic mechanisms effects such as phonon scattering become more pronounced. © 2011 IEEE.

TRANSIENT RESPONSE OF A BI-LAYERED MULTIFERROIC COMPOSITE PLATE

Acta Mechanica Solida Sinica 2011年第1期24卷 83-91页

In this paper, a three-dimensional finite-element formulation for the multiferroic composite is developed and implemented into the commercial software ABAQUS for its transient analysis. First, a special three-dimensional eight-node solid element is designed to handle the multiferroic composite made of elastic, piezoelectric, and piezomagnetic materials. Second, a userdefined subroutine for this newly developed element is implemented into ABAQUS. Finally, the transient responses of a bi-layered multiferroic composite are calculated by using the direct time integration method. Two typical magnetic potential signals, Gauss and Ricker pulses, are applied to the composite with various time durations of excitation. The induced electric field shows that the transient response can be substantially influenced by the input signal, which could be tuned for the strongest electric output.

We present a first version of an algorithm producing autonomously responses in wireless sensor networks in order to mitigate detected malfunction and misbehavior. We were inspired by the low level mechanisms for response conformation, the degenerate behavior of receptors, of T-cells in the human immune system. The proposed algorithm uses a co-stimulatory feedback in order to adapt to changing conditions, thus enabling the system to choose a different response when appropriate. We evaluate the algorithm on a simulation model in OMNet++ and demonstrate its applicability for wireless sensor networks. © 2011 Springer-Verlag.
