A Novel Prioritization Technique for Improving the Rate of Error Detection in Regression Testing
Thillaikarasi Muthusamy and Seetharaman.K
Test metrics provide the current degree of development in testing and gives a projection to proceed on with testing activities by leaving us to define objectives and future courses. The objective of test metrics is to determine the planned and actual amounts of effort, time, resources which requires to complete the evolution of the software project. Test cases increase the ability to take on some targets such as code coverage and rate of error detection. Here, we introduce a new metric based on varying requirement priorities, test case priorities, test case execution time and fault severities. The case study shows that the rate of test case priority per unit time can be increased and improved on quality testing and client satisfaction. To go over the practicality of this technique, we apply it as a realistic model of the industrial projects. Here, we summarize about test process measurement and analyze the effectiveness of metrics of price, time, quality of test process based on the effect of proposed metrics.

Micromegas Detector: Conception and Development based on Neon gasat High Energy Physics using 55Fe X-ray Source
HamidMounir and Seddik Bri
Recent years have seen the development of many fields of gas detectors. The MICROMEGAS (Micro-Mesh Gas Structure) appeared as the very promising detectors. It is major families of position detectors in High Energy Physics, detects and localizes energy deposit by photon and charged particles over large area. In this work, MATLAB simulations of This Detector are represented. The aim of this work is to simulate the principle parameters of MICROMEGAS detector (Townsend coefficients and amplification gain). We choose Neon-isobutane (Ne-iC4H10) and Ne-dimethyl-ether (Ne-DME) gas mixture, using 55Fe radioactive 5.9keV X-rays Source. In the normal condition, (T=298 K, p=1atm). The simulated results are nearly consistent with experimental data, and provide important information in the MICROMEGAS, concept and operating. Our simulation predicts that further improvements are still possible for give a best spatial and temporal resolution for MICROMEGAS detector.

On-Site Ultra Wide Band Construction Material Tracking System (UWB-CMTS)
Naeem Zafar Azeemi
On-site building material and constructiontools management offers a big challenge totraditional asset tracking systems. In the same vein, when construction machinery mobility is very frequent, data collection is often onerousfor busy construction crews. Construction managers determine the best way to track building material, construction tools and equipment to rationally layout the most cost-effective plan and schedule for completing the project. In contrast to conventional asset tracking schemes such as Radio Frequency IDs (RFID), Infra Red IDs (IRID), Tagged IDs (TID) to name a few, we use Ultra Wide Band (UWB) technology in our UWB Construction Material Tracking System (UWB-CMTS), that is relatively new and gaining researchers interest in imaging as well as in tracking. We transmit short impulses ranging from sub-nanoseconds to a few nanosecond are transmitted that have high material-penetration capability, low electromagnetic interference as well as lower specific absorption rates and good immunity against multipath interference. We model a typical building system into many segments such as structural framework, floors, and walls, including fire-protection, electrical, plumbing, air-conditioning, and heating. This methodology made our scheme well suited for geometry or contour based construction asset location estimation. We explore variability of tracking schemes for number of Ultra Wide Band (UWB) based radar tracking systems. Results are exposed for number of construction scenarios;UWB antennas were placed taking into accounts various UWB tag placements and reader locations. Robustness of system is verified across various position detection algorithms for e.g., Angle of Arrival (AoA), Received Signal Strength (RSS) and Time of Arrival (TOA).The system is expected to be useful in a large-scale construction machinery movement especially for construction projects, such as an office building or industrial complex.

Application of Forward/Reverse Osmosis Hybrid System for Seawater Desalination using Impaired Water from Steel Industry, Part (1): FO Performance
Hanaa M. Ali, Hanaa Gadallah, Sahar S. Ali, Rania Sabry and A. G. Gadallah
Forward osmosis is an osmotically driven membrane process that uses osmotic pressure of concentrated solutions, including seawater, to extract clean water from diluted solution. In a new approach, forward osmosis uses a saline stream to extract water from a source of impaired water. The driving force in forward osmosis is the difference in osmotic pressure between the saline water and the impaired water. This paper is a part one of two papers focus on the investigation of a forward osmosis – reverse osmosis hybrid process to co-treat seawater and impaired water from steel industry. By using this hybrid process, seawater can be diluted before desalination, hence reducing the energy cost of desalination, and simultaneously, contaminants present in the impaired water are prevented from migrating into the product water through the forward and reverse osmosis membranes. The main objective of this part is to obtain sufficient information for the operation of forward osmosis system. To achieve this goal, the experimental scheme has been constructed to identify the performance of the forward osmosis system with different membrane types and at different draw solution concentrations. In addition, the effect of different wastewater concentrations on the membrane performance and on water fluxes was demonstrated.

Madubueze, C.E., Ochugboju, A.O. and Nwaokolo, M.A.
The basic reproduction number R_o is an important threshold quantity used to determine whether or not an infectious disease will spread through a given population. This study focused on the computation of R_o for various epidemiological models using the next generation method and the method obeyed the threshold property of R_o. The impact of R_o on bifurcation (forward and backward bifurcation) was analysed at R_o=1 using the centre manifold theory for simple SEIR models and the result showed that forward bifurcation exist for SEIR model.

GOUSSOT Emmanuelle, BROU Yao Télesphore, LAOUINA Abdellah, CHAKER Miloud, EMRAN Anas, MACHOURI Nadia, MAHE Gil, Mohamed SFA and TRA BI Zamblé Armand
The landscapes of the Bouregreg watershed evolved under the effect of climatic factors through the episodes of drought which affect the country since the beginning of the 80s. In this context, the present study evaluates the land cover dynamic at the catchment scale between 1985 and 2007 based on satellite data (Landsat images). Our methodology uses remote sensing technique which allowed us to characterize and to study the evolution of different classes on the study area, that is to say agricultural plots, natural vegetation, bare ground, water and urban areas. Land cover maps were produced using a maximum likelihood classification. They highlight a progression of the urban areas of almost 54% as well as important fluctuations of agricultural land, natural vegetation and bare ground because of climatic variations and the development of human activities. Thereafter, these observations are compared to data resulting from agricultural statistics which confirm the results obtained from satellite data processing.
