3. TREND ANALYSES OF PARAMETERS OF EQUATIONS FOR MINIMUM FAIRNESS PROPORTION ACHIEVABLE IN UBICOMP MANETS USING LOCATION-AWARE TRANSMISSION.

Authors: M. KALEEM GALAMALI , NAWAZ MOHAMUDALLY

Abstract: Managing energy consumption in ubicomp remains a significant topic of research. To assist in this issue, MANET transmission may be prone to future successes [74]. Despite all development of strategies for energy containment in MANETs, including application of location-aware transmission, it is still true that the software engineering notion of modelling in ubicomp is in its embryonic phases. Energy management is crucial because of constrained battery power of ubicomp nodes and its cost implications. A prior study was carried out [23] to quantify and model the Minimum Fairness Proportion (Min_FP) recordable for CBRs for node densities of 7 until 56. The corresponding model was perceived to be the decreasing exponential model. In this paper, the next level of investigation is set forth as: “What are the trends of variation observable within each parameter of the equation of curve obtained for metric Min_FP [23] over varying node densities?” Studying the behaviour of components of applica

Authors: ALI.M.A.IBRAHIM , SAMI ABBAS NAGAR , AMMAR ABDELRAHIM MUDDATHIR , HADEEL KHAIRY A.ALDALY , OSAMA MOHAMEDAHMED SULIMAN

Abstract: there is a rapid growth in cellu lar networks due to the huge turnout for it, but all this happening without the current generations being fully utilized in terms of spectrum. Due to the nature of the cellular system where areas are divided into cells that have limited capacity, some area s might have larger populations causing the full utilization (congestion) of the cell whereas other areas might be serving a far less user base leading to the underutilization of the cell meaning that the overall system isn’t utilized properly. In order to solve this problem load balancing has been proposed with different approaches that ranged from tinkering with the cell reselection parameters or the cell’s shape and coverage. However these methods have failed to catch on thus far for a number of reasons and load balancing is still currently done manually using radio engineers. In our research we explore a mathematical model for load balancing in 4G LTE networks. We have proposed the addition of Wi

Authors: HIROAKI HIGAKI

Abstract: In a large - scale high - rise building, elevator systems with multiple elevator cars supports m obility of users. Since current elevator controller system s o nly achieve user’s requirements as the existence of requests of mobility directions in each flo or, it is difficult for multiple elevator cars to stop at the same floor simultaneously even if there exist unevenly distributed requests in some specific flo ors. This results in low service ratio causing numbers of bumped passengers and in longer waiting time duration of the users. This pa per proposes a novel method for registrations of user’s requests through a smartphone application. Due to achievement of mo bili ty request of each user through his/her personal device, the elevator controller system acquires numbers and distribution of i ndividual mobility requests and detailed control of elevator cars including simultaneous stops of multiple elevator cars at th e same floor is realized.

Abstract: The purpose of this paper, is to provide a solution to the issue of dependence for elderly people in the context of an ageing population phenomenon. In rural areas with a low population density, isolation has negative impacts on everyday life. In France, the ageing population raises the fear of a serious increase in the number of persons suffering from disabilities and in need of assistance. In Corsica, population ag e ing is substantially increasing. Given this critical context we are try ing to develop a system of connected objects called SmartAngels to support proximity - based solidarity. It consists of a meshed network of autonomous Zi g Bee microcontrollers, in which various actors can exchange information by means of an accurate interface design. Its main task is to support both proximity - based solidarity and social relat ionship s in rural environments. Moreover, the SmartAngels device grid ensures optimal neighbo u rhood solidarity in case of a serious problem by creating a

Authors: CHULSOON PARK , HONGSUK SUNG , SANGCHEON LEE , SUNGMOON BAE

Abstract: The market size of plant projects in overseas is so large that domestic EPC project contractors are actively seek ing the overseas projects and then trying to meet completion plans since successful fulfillment of these projects can provide great opportunities for them to expand into new foreign markets. International EPC projects involve all of the uncertainties commo n to domestic projects as well as uncertainties specific to foreign projects including marine transportation, customs, regulations, nationality, culture and so on. When overseas project gets off - schedule, the resulting uncertainty may trigger unexpected ex ceptions and then critical effects to the project performance. It usually require much more time and costs to encounter these exceptions in foreign sites compared to domestic project sites. Therefore, an exception handling approach is required to manage ex ceptions effectively for successful project progress in foreign project sites. In this research, we proposed a me

Abstract: Too often, the unified security programs, based on comprehensive analy ses of unified information from across the IT infrastructure, are costly, complex, difficult to implement and inefficient. As a result, most organizations lack accurate threat detection and informed risk - management capabilities. Therefore, the response to new information security threats can be a “security intelligence” approach. It is based on art ificial intelligence and the use of its methods to protect from cybercrimes. The aim of this study is to present and compare different methods of artificial intel ligence for fighting the crime in cyberspace, or rather their application in systems for detecting and preventing intrusions

Authors: DJAMILA BOUAISSA , RACHID CHALAL

Abstract: One among the major concerns of managers since the emergence of Information Technology (IT) in organizations in the sixties is to prove that the IT /IS (information system) investments have a positive impact on the organization. Over time, the IS’s evaluation dominated the research in IS field. Several variables of IS measurement, called IS success measurements, like user satisfaction, system use, organizational performance and u ser decisional performance [41 ] were developed and considered as substitute for the effectiveness of IS (IS e ffectiveness is measured against the achievement of objectives according to Hamilton and Chervany [ 25 ]). User satisfaction is the most use d in measuring the success of IS and their impact on the organization. This article focuses on the "user satisfaction". Through the analysis of a set of selected articles from the literature about the evaluation of IS , w e have developed a class model (using UML formalism) about the construct user satisfaction.

Authors: PATHA SREEDHAR , SURYAKANTH V. GANGASHETTY

Abstract: The proposed work exploits acoustic cues at various levels and incorporates them in the present (Spoken Term Detection) STD frame work. Recently proposed new syllabification method [1] for speech signal is being used for STD . In STD, a query and reference speech signals are provided, these speech signals are syllabified using the new syllabification method and features like Mel - frequency cepstral coefficients (MFCC), posterior grams are extracted. These features are then matc hed using template based match techniques like dynamic time warping (DTW) at syllable level instead of regular frame level. This essentially reduces the unwanted matching done at frame level.
