ABSTRACT

Cultural understanding and environment of upbringing plays a pivotal role in deciding right and wrong that influences our perception and decision-making. Electroencephalogram (EEG) is being employed since past several years to understand cognitive functioning of human brain. Here, we employed EEG to determine impact in cognitive functioning due to cultural upbringing. The objective was to detect if there is any influence of difference in cultural understanding related to alcohol use, on EEG obtained from alcohol consumers and non-consumers. The present study was done between Indo-Aryan and Tibeto Burman linguistic groups from Shillong Meghalaya. Embedding dimension was used to characterize EEG. The embedding dimension from the frontal and occipital regions of the brain of both alcohol consumers and non-consumers in Tibeto Burmans and Indo Aryans were determined via a MATLAB program. The results show that the embedding dimension profiles of alcohol consumers and non-consumers are quite different. For the control (non consumers) both in case of Tibeto Burman and Indo Aryans the value of the embedding dimension was higher in occipital regions as compared to the alcohol consumers. This result implies the loss of coherence and neuronal connectivity for alcohol consumers. However, this effect is more prominent in the case of Indo Aryans.

Author : Srikumar Sandeep1 and Alexander Kokhanovsky2

Volume, Issue, Month, Year : Vol (1), No (4), October, 2016


ABSTRACT

Accurate modeling of light scattering from nanometer scale defects on Silicon wafersiscritical for enabling increasingly shrinking semiconductor technology nodes of the future. Yet, such modeling of defect scattering remains unsolved since existing modeling techniques fail to account for complex defect and wafer geometries. Here, we present results of laser beam scattering from spherical and ellipsoidal particles located on the surface of a silicon wafer. A commercially available electromagnetic field solver (HFSS) was deployed on a multiprocessor cluster to obtain results with previously unknown accuracy down to light scattering intensity of -170 dB. We compute three dimensional scattering patterns of silicon nanospheres located on a semiconductor wafer for both perpendicular and parallel polarization and show the effect of sphere size on scattering. We further computer scattering patterns of nanometer scale ellipsoidal particles having different orientation angles and unveil the effects of ellipsoidal orientation on scattering.

Multi Model Data Mining Approach for Heart Failure Prediction

Author : Priyanka H U, Vivek R
Volume, Issue, Month, Year : Volume 6, Number 5, September, 2016

ABSTRACT

Developing predictive modelling solutions for risk estimation is extremely challenging in health-care

informatics. Risk estimation involves integration of heterogeneous clinical sources having different

representation from different health-care provider making the task increasingly complex. Such sources are typically voluminous, diverse, and significantly change over the time. Therefore, distributed and parallel computing tools collectively termed big data tools are in need which can synthesize and assist the physician to make right clinical decisions. In this work we propose multi-model predictive architecture, a novel approach for combining the predictive ability of multiple models for better prediction accuracy. We demonstrate the effectiveness and efficiency of the proposed work on data from Framingham Heart study. Results show that the proposed multi-model predictive architecture is able to provide better accuracy than best model approach. By modelling the error of predictive models we are able to choose sub set of models which yields accurate results. More information was modelled into system by multi-level mining which has resulted in enhanced predictive accuracy.

Author : Kwanwoong Ryu, You-Seok Lee, Jae-Hyun Seo, and Heung Mook Kim
Volume, Issue, Month, Year : Volume 38, Number 5, October, 2016

ABSTRACT

In this paper, we propose an emergency wake-up alert system (EWAS) for providing accurate and rapid emergency information. The proposed system can provide an emergency wake-up alert service without an additional frequency allotment by utilizing the guard band of the Advanced Television Systems Committee (ATSC) Terrestrial Digital Television (DTV) system. The design target of the proposed system is to match the indoor reception coverage of EWAS with the outdoor reception coverage of the ATSC DTV system. To achieve this, the proposed system should be about 35.65 dB more robust than the ATSC DTV system. The simulation results show that the proposed system offers an emergency wake-up alert service supporting a data rate of up to 23 bps.

DESIGN OF TWO CONTROLLERS BASED ON DMRAC AND MIT METHODS ON GLUCOSE-INSULIN SYSTEM

Author : Karima Menani and Mourad Abdelaziz
Volume, Issue, Month, Year : Vol (1), No (1), September, 2016

ABSTRACT

This paper presents a closed-loop control system with regulating blood glucose level in type-1 diabetic patients. The contribution of this paper is twofold for controlling the glucose level in insulin. Firstly a direct model reference adaptive control algorithm (DMRAC) for the glucose insulin system is considered based on the command generator tracker (CGT). Secondly, another significant control MIT adaptive control method (MITC) is desired to obtain a comparative study between the two proposed controllers. The achievement of our study is to affect these two algorithms for the regulation of the glucose level in type 1 diabetes, because the problem of the diabetes is one of the largest difficulties necessities a methods for treating the disease. Diabetes is a malfunction in the glucose-insulin system; so ours controllers can successfully assure that the blood glucose levels should be maintained between 80 mg/dl and 120 mg/dl before meals; less than 180 gm/dl after meals. The application of these controllers is tested in silico foreffective diabetic I patients. The simulations demonstrate that the developed algorithms lead to an asymptotically stable error and illustrate the validity of the algorithms.

A FRAMEWORK FOR INTEGRATING USABILITY PRACTICES INTO SMALL-SIZED SOFTWARE DEVELOPMENT ORGANIZATIONS

Author : Lulwa Alyahyan, Khalid Alnafjan, and Hamza Aldabbas
Volume, Issue, Month, Year : Vol.7, No.5, September, 2016

ABSTRACT

Usability now appears to be a highly important attribute for software quality; it is a critical factor that

needs to be considered by every software-development organization when developing software to improve customer satisfaction and increase competition in the market. There exists a lack of a reference model or framework for small-sized software-development organizations to indicate which usability practices should be implemented, and where in the system-development life cycle they need to be considered. We offer developers who have the objective of integrating usability practices into their development life cycle a framework that characterizes 10 selected user-centered design (UCD) methods in relation to five relevant criteria based on some ISO factors that have an effect on the selection of methods (ISO/TR16982). The selection of the methods for inclusion in the framework responds to these organizations’ needs; and we selected basic methods that are recommended, cost-effective, simple to plan and apply, and easy to learn by developers; and which can be applied when time, resources, skills, and expertise are limited. We favor methods that are generally applicable across a wide range of development environments. The selected methods are organized in the framework according to the stages in the development process where they might be applied. The only requirement for the existing development life cycle is that it to be based on an iterative approach.

Opinion Retrieval for Twitter Using Extrinsic Information

Author : Yoon-Sung Kim, Young-In Song, Hae-Chang Rim
Volume, Issue, Month, Year : 22, 5, June, 2016

Abstract:

Opinion retrieval in social networks is a very useful field for industry because it can provide a facility for monitoring opinions about a product, person or issue in real time. An opinion retrieval system generally retrieves topically relevant and subjective documents based on topical relevance and a degree of subjectivity. Previous studies on opinion retrieval only considered the intrinsic features of original tweet documents and thus suffer from the data sparseness problem. In this paper, we propose a method of utilizing the extrinsic information of the original tweet and solving the data sparseness problem. We have found useful extrinsic features of related tweets, which can properly measure the degree of subjectivity of the original tweet. When we performed an opinion retrieval experiment including proposed extrinsic features within a learning-to-rank framework, the proposed model significantly outperformed both the baseline system and the state-of-the-art opinion retrieval system in terms of Mean Average Precision (MAP) and Precision@K (P@K) metrics.

ANALYSIS OF LIGHTNING STRIKE WITH CORONA ON OHTL NEAR THE SUBSTATION BY EMTP

Author : Zahira ANANE , AbdElhafid BAYADI and Alen Bernadi
Volume, Issue, Month, Year : Vol (1), No (1), September, 2016

ABSTRACT

Lightning protection and insulation coordination of transmission lines and substations require an accurate knowledge of the magnitudes and waveforms of lightning overvoltage. To simulate the lightning overvoltage precisely near the substation, this study has shown how to consider the lightning impulse corona for distortion effect of this overvoltage. Attenuation and deformation effects of lightning impulse corona along transmission lines are evaluated by the simulation results. This paper describes the substation equipment modeling in the software Electromagnetic Transients Program–Alternative Transients Program EMTP. Corona effect is incorporate in order to estimate the attenuation and deformation of overvoltage’s travelling waves on transmission lines near substations. Variations of lightning stroke current magnitudes, protection distances, and the impact points are obvious due to the applied dynamic corona model. Several elements of substation equipment are modeled in ATP/EMTP using MODELS language. The Simulation results show that the amplitude and voltage travelling wave-fronts attenuated remarkably. Deformation of the wave shapes mainly occurs when the impulse voltage exceeds the corona inception voltage.

Fast Prediction Mode Decision in HEVC Using a Pseudo Rate-Distortion Based on Separated Encoding Structure

Author : Jinwuk Seok, Younhee Kim, Myungseok Ki, Hui Yong Kim, and Jin Soo Choi
Volume, Issue, Month, Year : Volume 38, Number 5, October, 2016

Abstract

A novel fast algorithm is suggested for a coding unit (CU) mode decision using pseudo rate-distortion based on a separated encoding structure in High Efficiency Video Coding (HEVC). A conventional HEVC encoder requires a large computational time for a CU mode prediction because prediction and transformation procedures are applied to obtain a rate-distortion cost. Hence, for the practical application of HEVC encoding, it is necessary to significantly reduce the computational time of CU mode prediction. As described in this paper, under the proposed separated encoder structure, it is possible to decide the CU prediction mode without a full processing of the prediction and transformation to obtain a rate-distortion cost based on a suitable condition. Furthermore, to construct a suitable condition to improve the encoding speed, we employ a pseudo rate-distortion estimation based on a Hadamard transformation and a simple quantization. The experimental results show that the proposed method achieves a 38.68% reduction in the total encoding time with a similar coding performance to that of the HEVC reference model.

NEW EXPERIMENT SYSTEM FOR THE INTERACTION BETWEEN SOFT ROCK AND WATER: A CASE STUDY ON THE MOGAO GROTTOES SUPPORT ROCK

Author : Zhu Guolong, Qin Xinzhan, Hao Nai and Zhang Fang
Volume, Issue, Month, Year : 3, 3, September, 2016


ABSTRACT

The strength of rock strongly depends on the water content especially when the rocks contain clay

materials. The interaction between soft rock and water always threaten the soft rock engineering projects. For this problem, new sets of laboratory experiment systems are developed to simulate the interaction between soft rock and water or vapor. In this paper, the principles of experiment systems are introduced with particular reference to the application on soft rock in Mogao Grottoes, one of the world famous ancient sites in China. Two kinds of rock samples, the sandstone and muddy sandstone, are obtained by insitu sampling system. Then the laboratory experiments are performed under different environment conditions. By the specific boundary conditions design, the physical-chemical effect and mechanic effect on water absorption of rock samples are separated for further mechanism study by the experiment system, and the different hydrological actions of water and vapor under variable experiment environment are obtained. The interaction mechanism is discussed with assistant methods, such as SEM (Scanning Electron Microscope), mercury injection test, X-ray diffraction analysis and etc. With the relation between water content and soft rock strength, the study may provide guidance and basis for the soft rock engineering in the future.

EVALUATION OF A NEW INCREMENTAL CLASSIFICATION TREE ALGORITHM FOR MINING HIGH SPEED DATA STREAMS

Author : N. Sivakumar
Volume, Issue, Month, Year : 3, 3, September, 2016

ABSTRACT

Abstract—A new model for online machine learning process of high speed data stream is proposed,to

minimize the severe restrictions associated with the existing computer learning algorithms. Most of the existing models have three principle steps. In the first step, the system would create a model incrementally. In the second step the time taken by the examples to complete a prescribed procedure with their arrival speed is computed. In the third and final step of the model the size of memory required for computation is predicted in advance. To overcome these restrictions we proposed this new data stream classification algorithm, where the data can be partitioned into stream of trees. In this algorithm, the new data set can be updated with the existing tree. This algorithm, called incremental classification tree algorithm, is proved to be an excellent solution for processing larger data streams. In this paper, we present the experimental results of our new algorithm and prove that our method would eradicate the problems of the existing method.

Reusable HEVC Design in 3D-HEVC

Author : Young Su Heo, Gun Bang, and Gwang Hoon Park

Volume, Issue, Month, Year : Volume 38, Number 5, October, 2016

Abstract

This paper proposes a reusable design for the merging process used in three-dimensional High Efficiency Video Coding (3D-HEVC), which can significantly reduce the implementation complexity by eliminating duplicated module redundancies. The majority of inter-prediction coding tools used in 3D-HEVC are utilized through a merge mode, whose extended merging process is based on built-in integration to completely wrap around the HEVC merging process. Consequently, the implementation complexity is unavoidably very high. To facilitate easy market implementation, the design of a legacy codec should be reused in an extended codec if possible. The proposed 3D-HEVC merging process is divided into the base merging process of reusing HEVC modules and reprocessing process of refining the existing processes that have been newly introduced or modified for 3D-HEVC. To create a reusable design, the causal and mutual dependencies between the newly added modules for 3D-HEVC and the reused HEVC modules are eliminated, and the ineffective methods are simplified. In an application of the proposed reusable design, the duplicated reimplementation of HEVC modules, which account for 50.7% of the 3D-HEVC merging process, can be eliminated while maintaining the same coding efficiency. The proposed method has been adopted as a normative coding tool in the 3D-HEVC international standard.

Performance Evaluation of Mobile WIMAX IEEE 802.16E for Hard Handover

Author : Amira Youssef Fahoud and D.K. Lobiyal
Volume, Issue, Month, Year : Vol.8, No.5, Sept, September, 2016

ABSTRACT

Seamless handover in wireless networks is to guarantee both service continuity and service quality. In

WiMAX, providing scalability and quality of service for multimedia services during handover is a main challenge because of high latency and packet loss. In this paper, we created four scenarios using Qualnet 5.2 Network Simulator to analyze the hard handover functionality of WiMAX under different conditions. The scenarios such as Flag with 5 and 10 sec UCD and DCD interval values, Random mobility scenario and DEM scenario using 6 WiMAX Cells have been considered. This study is performed over the real urban area of JNU where we have used JNU map for scenarios 1, 2 and 3 but for scenario 4, the JNU terrain data has been used. Further, each BS of 6 WiMAX cell is connected to four nodes. All nodes of each scenario are fixed except Node 1. Node 1 is moving and performing the handover between the different BSs while sending and receiving real time traffics. Flag mobility model is used in Scenario 1, 2 and 4 to model the movement of the Node 1 while we use random mobility model in sceanrio3. 5 seconds time interval is used for Scenarios 1, 3, and 4 while 10 seconds time interval is used for scenario 2 to study the effect of management messages load on handover. Further, the statistical measures of handover performance of WiMAX in terms of number of handover performed, throughput, end-to-end delay, jitter, and packets dropped are observed and evaluated.

MPEG Surround Extension Technique for MPEG-H 3D Audio

Author : Seungkwon Beack, Jongmo Sung, Jeongil Seo, and Taejin Lee
Volume, Issue, Month, Year : Volume 38, Number 5, October, 2016

Abstract

In this paper, we introduce extension tools for MPEG Surround, which were recently adopted as MPEG-H 3D Audio tools by the ISO/MPEG standardization group. MPEG-H 3D Audio is a next-generation technology for representing spatial audio in an immersive manner. However, considerably large numbers of input signals can degrade the compression performance during a low bitrate operation. The proposed extension of MPEG Surround was basically designed based on the original MPEG Surround technology, where the limitations of MPEG Surround were revised by adopting a new coding structure. The proposed MPEG-H 3D Audio technologies will play a pivotal role in dramatically improving the sound quality during a lower bitrate operation.

Tunnel Field-Effect Transistors: Prospects and Challenges

Author : Uygar E. Avci ; Daniel H. Morris ; Ian A. Young

Volume, Issue, Month, Year : 3, 2, May, 2015

ABSTRACT 

The tunnel field-effect transistor (TFET) is considered a future transistor option due to its steep-slope prospects and the resulting advantages in operating at low supply voltage (VDD). In this paper, using atomistic quantum models that are in agreement with experimental TFET devices, we are reviewing TFETs prospects at LG = 13 nm node together with the main challenges and benefits of its implementation. Significant power savings at iso-performance to CMOS are shown for GaSb/InAs TFET, but only for performance targets which use lower than conventional VDD. Also, P-TFET current-drive is between 1× to 0.5× of N-TFET, depending on choice of IOFF and VDD. There are many challenges to realizing TFETs in products, such as the requirement of high quality III–V materials and oxides with very thin body dimensions, and the TFET’s layout density and reliability issues due to its source/drain asymmetry. Yet, extremely parallelizable products, such as graphics cores, show the prospect of longer battery life at a cost of some chip area.

Design of Synchronization and T-STD Model for 3DTV Service over Hybrid Networks

Author: Kugjin Yun, Won-Sik Cheong, Gwangsoon Lee, Xiaorui Li, and Kyuheon Kim

 Volume, Issue, Month, Year:Volume 38, Number 5, October, 2016

Abstract:
The objective of digital broadcasting has evolved from providing a plain video service to offering a realistic visual experience. Technologies such as 3DTV and UHDTV have been suggested to achieve this new objective by providing an immersive and stereoscopic visual experience. However, owing to the high bandwidth requirements of such services, the broadcasting industry has faced a challenge to find a new transport mechanism for overcoming the bandwidth limitation. The standardization organizations, the Advanced Television Systems Committee, Digital Video Broadcasting, and Telecommunications Technology Association, have been working on the integration of broadcasting and a broadband network (IP) to resolve the bandwidth issue of realistic video services. This paper introduces a frame-level timeline synchronization and transport system target decoder model for providing a stable 3DTV service over a hybrid network. The experimental results indicate that the proposed technologies can be successfully adopted as a reference model in a broadcast-broadband hybrid 3DTV service and other IP-associated hybrid broadcasting services.
