Groundwater Investigation using 2-D Electrical Resistivity Imaging (ERI) at Ilubirin, Southwestern Nigeria[Full-Text ] A. I. Olayinka, M. O. Oladunjoye, A. O. KorodeleThere have been reported cases that the presence of tar sands deposits that are startigraphically and structurally controlled within the study has penetrated (seep) into the hand-dug wells causing blockage to the flow of groundwater; subsequently leading to contamination making groundwater unpalatable to the people within the area. In this research, non-destructive geophysical investigation techniques comprising eight 2-D Electrical Resistivity Imaging (ERI) were taken with Wenner Configuration at Ilubirin, Southwestern, Nigeria. The Electrical Resistivity Imaging has a maximum electrode spacing (AB) of 150m. Two Electrical Resistivity Imaging profiles were taken very close to the contaminated hand dug well along the area where tar sands seepages were sighted. The current and potential electrodes were kept constant at equal interval to one another with the potential electrodes in the middle. The result obtained showed that areas with depression having true resistivity ranging from 192Ωm to 426Ωm with a geological formation described as clayey sand can serve as very good groundwater potential zones which are probably not vulnerable to contamination if proper groundwater management is done.

Spectral Clustering Ensemble and Unsupervised Clustering for Land cover Identification in High Spatial Resolution Satellite Images[Full-Text ] A Narendranath reddy and NimmagaddaPadmajaUnsupervised clustering plays a dominant role in detailed landcover identification specifically in agricultural and environmental monitoring of high spatial resolution remote sensing images. A method called Approximate Spectral Clustering enables spectral partitioning for big datasets to extract clusters with different characteristic without a parametric model. Various information types are used through advanced similarity criteria. Selection of similarity criterion optimal for the corresponding application is required. To solve this issue a Spectral Clustering Method is proposed which fuses partitioning obtained by distinct similarity representations. This Spectral Clustering Ensemble adopts neural Quantization in the place of Random Sampling, and advanced similarity criterion in the place of Gaussian kernel distance with distinct decaying parameters, and a two level ensemble. The built up areas in the high resolution images can be detected using unsupervised detection. In this process first, a large set of corners from each of the input images are extracted by an improved Harris corner detector. Then, the extracted corners are incorporated into a likelihood function to discover candidate regions in each input image. Given a set of candidate build-up regions, in the second stage, the problem of build-up area detection is concised as an unsupervised grouping problem. The performance of these algorithms is evaluated by Accuracy, Adjusted Rand Index (ARI) and Normalized Mutual Information (NMI). Experimental results show a significant betterment of the resulting partitioning obtained by the proposed ensemble, with respect to the evaluation measures in the applications.

Fluid Dynamics inside a Mini-scale Microbial Energy Harvesting System[Full-Text ] Way Lee Cheng, Kumaran Kannaiyan, Reza Sadr, and Arum HanMicrobial electrochemical cells are an interesting energy harvesting system that utilizes various carbon sources such as wastewater. Fluid inside the system is replenished at regular frequencies to supply nutrients to the catalytic microbes for continuous energy production. However, the replenishment process can be a challenge in micro-scale devices as the flow field inside is often laminar. Whereas, the high flow rate is not desired as the resulting high fluid shear can disrupt the catalytic microbes. To this end, the computational fluid dynamics simulations are performed to study the effect of design configurations on the replenishment efficiency. The results show that the success rate of replenishment is only about 55 % to 60 % when the inlet and outlet ports are located close to each other. The maximum efficiency obtained with the optimal design is only 70 %, which is typically not accounted for most of the experiments. Hence, there is a possibility of significant error when calculating the nutrient utilization rates, which in turn can affect the system efficiency. Furthermore, other design factors that affect the replenishment such as the distance between inlet and outlet ports and the orientation of the inlet and outlet ports are investigated.

Performance comparison between Hysteresis Controller (HC) and Proportional Integral (PI) Controller for Resistance Spot Welding System[Full-Text ] Rama Subbanna.S, Dr.M.SuryakalavathiThe objective of this paper is to compare the saturation level control performance between Hysteresis Controller and PI controller in a middle-frequency direct current (MFDC) resistance spot welding system(RSWS). It consists of an input converter, welding transformer, and a full-wave rectifier mounted at the transformer secondary. The unequalohmic resistances of the two transformer’s secondary circuits and the different characteristics of the diodes of output rectifier certainly lead to the magnetic core saturation which, consequently, causes the unwanted spikes in the transformer’s primary current and over-current protection switch-off. The goal is to determine which control strategy gives better performance with respect to the magnetic core saturation. The two controllers presented such as HC and PI controllers for controlling the saturation level in the magnetic core of a welding transformer of highly nonlinear system of RSWS. The simulation study has been done in Matlab/Simulink environment shows that both controllers are capable to control the saturation level in the core of welding transformer successfully. The result shows that PI controller delivered the better response compared to HC controller. Responses are presented here with details analysis.

WORK LIFE IMBALANCE OF EMPLOYEES IN IT SECTOR- A STUDY CONDUCTED AT NEST TECHNOLOGIES, TRIVANDRUM[Full-Text ] Sakeerthi S, Rijesh K BHRM is the most crucial part of any organization. Because of the changing work scenarios, the complexity of HRM is also increasing. From the time where men used to earn and women used to take care of the household, a phase has arrived where both the male and female counter part of the family equally contribute to the family income. Along with this, a new concern has also emerged, that of the “work life imbalance”. It’s a condition where a person finds difficulty in hitting a proper balance between his professional and personal life. And with the increasing number of females working, the problem has become a matter of serious concern. Many find it very difficult to carry along their personal and professional lives together resulting in professional failures and breaking up of family relations. Many recent studies have brought out the alarming rates of divorces among IT couples and this is also one of the aftermaths of work life imbalances. Many also get into serious physical and mental ailments unable to handle their personal life and job together. Hence this topic has become very relevant in today’s work scenarios. In this article, an attempt has been made to throw light on the issues of work life imbalance and some reasonable solutions have been suggested to hit the proper balance between personal and professional life based on a study conducted at the IT major, NeST Technologies, Technopark, Trivandrum. The study was conducted on a sample of 100 employees among the total population of 1000 employees working in the Trivandrum office of NeST using a questionnaire.

A New Cooperative Learning Framework in Mathematic Courses[Full-Text ] Seifedine Kadry and Rabih RoufayelIt is widely known that mathematics plays a major role in handling real life problems related to members in a society and serves in shaping both private and public sectors of a given community. Many students have showed signs of discomfort when dealing with mathematics, becoming more and more dissatisfied as they confront challenges to engagements. Solving this dilemma requires to search and develop an effective and suitable learning methodology that serves as a guiding tool in modern teaching. Recently, a new educational technique strategy “Active Learning” was implemented in many educational industries. This strategy briefly describes as a wide range of learning activities engaged by students in a classroom other than listening passively to an instructor’s lecture. It involves student’s engagement in critical thinking thus expressing and passing over ideas in small groups that can be illustrated by receiving immediate feedback from the instructor. The term cooperative learning covers the subset of active-learning activities that students perform in groups of three or more, rather than alone or in pairs. This paper shows a new learning methodology in mathematics based on cooperation between students with different educational background level. The main idea behind this cooperative method is to increase class average and on the other hand, to decrease the variance and range between students’ critical thinking and knowledge levels. The proposed methodology in this study shows the advantages of active learning and the power of student centered approach.

The equal channel angular pressing is the mostly used process among them. During the use of this process on zinc 22% aluminum alloy grain refined by molybdenum in the mechanically dry condition, i.e. without lubrication, the pressed work piece was segmented on its interface in contact the ECAP die; similar to the serrated chip observed in turning of low Ernst and Merchant in 1940 and recently observed in high speed turning of stainless steel and other metallic alloys at high values of feed rate and depths of cut. In this paper, the mechanism of formation of the ZA22 in the ECAP process and the serrated chips in the high speed turning of stainless steel and other material is presented and discussed. Furthermore, it was found that the number of segments and the distance between them, (the pitch) was varied depending on the chemical composition of the work piece material. Also the causes of this new phenomenon, the mechanism of its formation and how to avoid its occurrence are also presented and discussed. Finally, the segmented specimens were sectioned, projected, magnified and presented in the paper. The presented work in this paper is expected to be of value not only to the development of the ECAP process but also in the high speed turning process and also of special importance to grinding and polishing processes which results in further enhancement of the surface quality.

Molecular Detection of Fluoroquinolone Resistance in Multidrug Resistant Mycobacterium tuberculosisUsinggyrA[Full-Text ] RishamHussain, Dr. NasirMahmoodTuberculosis is one of the leading causes of death worldwide. WHO 2015 report indicates that Pakistan ranks fourth among multidrug resistant tuberculosis (MDR-TB) cases reportedglobally.Fluoroquinolones (FQ) are the primary broad spectrum antibiotics used for the treatment of MDR-TB and recent studies indicate a rapid rise in FQ resistance. This study focuses on the molecular detection of fluoroquinolone resistance in multi-drug resistant tuberculosis patients and the analysis of mutations occurrence in gyrA, at codons 90, 91 and 94.A total of 60 sputum cultured samples were analyzedthrough allele specific polymerase chain reaction (ASPCR) with self-designed primers. Among the 60 isolates examined, 36 (60%) were positive for gyrA mutations at codons 90, 91 and 94 while 24 (40%) were negative. The highest occurrence of mutations was found at codon 94 (37%), followed by mutations at codon 90 (20%) and at codon 91 (3%). Results indicate an increasing trend of FQ resistance in Pakistan. This study indicates molecular detection of TBto be faster and consistent and holds promise as a diagnostic tool for rapid screening of FQ resistance among MDR-TB patients to ensure its control and appropriate treatment.

Review Article Homo Erectus & Pale anthropological Record in the Narmada Rift Valley Madhya Pradesh & Gujarat State[Full-Text ] Maria Aziz, A A KhanThe Narmada Rift valley is conspicuous ENE-WSW to E-W trending prominent composite structural system across Indian sub-continent. It consists of various blocks which are dislocated and faulted along various faults and lineaments in space and time. The Narmada Rift System consists of various sub- basins like Hiran, Sher, Shakkar, Dudhi,Tawa, which are minor basins are integrated and in built part of main rift System. These sub basins possess imprints of rinsing sinking and rifting events. These imprints are recorded in terms of manifestation and signature on landscape, drainage, of land form elements, present and paleo- meandering signature, river terraces, cut of meanders, paleo- channels, scars, rock cut terraces, entrenchment and linear and curvilinear scars. These sub basins have developed transverse to the main axis of Narmada rifting and had deep cut across the quaternary blanket. The evolution of Narmada graben is differential and asymmetrical with rinsing and sinking valley floor. The Narmada basin contains fossiliferous Pliocene–Pleistocene volcanic fabrics sediments and volcanic rocks which were occupied by early hominid populations. The Main Narmada rift is both symmetrical and asymmetrical in different segments along its length of about 1300 km. Several paleoanthropological localities, archeological sites ranging in age from the Pliocene-Pleistocene times were discovered within these basins. The discovery of Human Skull Homo erectus form boulder conglomerate bed of Hathnora formation Khan (1992) by Sonakia (1984) De Lumley. and Sonakia, (1985): in Sehore district M.P.India was first fossil skull of fossil man from Indian sub-continent. It is correlated with Homo-eructs of China on Quaternary Platform is found to be the oldest homo-erectus in Asia Khan et.al (2013)
