Rajwinder Singh
American Journal of Industrial and Business Management (AJIBM) , 2013, DOI: 10.4236/ajibm.2013.35054
Abstract:

Garment retailing is a sunrise industry in India. However, the industrial competitiveness has posed many challenges for the organized garment retailers in this sector. In this paper an attempt has been made to identify the challenges based on strong literature support in consultation of practitioners and consultants in this industry. This study has classified the retail challenges for organizing garment retailing into four factors 1) sourcing challenges; 2) locational challenges; 3) environmental challenges and 4) customer challenges. Also we have identified items for organizational performance as well as for competitive advantage. A confirmatory model has been used to test the hypotheses; (H1): Retailers understand the match between competitive advantage and organizational performance; (H2): They understand the match between retail challenges and organizational performance; and (H3): They understand the match between retail challenges and competitive advantage using structural equation modeling. This study shall help the organized garment retailer to know more about the business.

Testing for Price Co-Integration between Producers and Retailers: Evidence from Ethiopian Milk Market  [PDF]
Habtamu Regassa Lemma, Rajwinder Singh
iBusiness (IB) , 2015, DOI: 10.4236/ib.2015.71001
Abstract: The purpose of this paper is to test how producers’ and retailers’ prices are horizontally integrated, and to show the direction of causality that exists between producers’ price and retails’ price in Ethiopian milk market. The study was conducted making use of secondary data extracted from Ethiopian central statistics agency. The data was time series having 120 observations of monthly recorded price series of producers and retailers, for the period from January, 2004 to December 2013. For this purpose, descriptive statistics and time series econometrics approach (Johansen’s test for co-integration and Vector Error Correction Model) were employed. The study shows that there is strong long run co-integration between producers’ price and retailers’ price. The policy implication is that the markets are co-integrated in terms of price transmission. However, the causality test shows that retailers are dominant over price determination. In other words, producer’s price is caused by retailers’ price; but producers’ price doesn’t cause retailers’ price. This shows that the market structure is in favor of retailers/traders, which can adversely affect the welfare of producers and consumers.
Organizational Performance and Retail Challenges: A Structural Equation Approach  [PDF]
Rajwinder Singh, Harminder Singh Sandhu, Bhimaraya A. Metri, Rajinder Kaur
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.32022
Abstract: Organized retailing is a sunrise industry in India. Many big industrial houses and international players are in the arena. The perfect competition in the market posed many challenges to retailers for better organizational performance. In this study we attempt to identify items for retail challenges (RC) and organizational performance (OP) based on strong literature support in consultation of practitioners and consultants in the field of organized non-livestock retailing (NLR). The retail challenges so selected were classified with factor analysis using principal component analysis with varimax rotation. Here, the retail challenges are classified into four categories as: strategic challenges, environmental challenges, customer challenges, and supply chain (SC) challenges. The six identified items for organizational performance are: market performance, SC competencies, stakeholder satisfaction, innovation and learning, customer satisfaction, and financial performance. A confirmatory model was tested using structural equation modeling to prove hypotheses: strategic challenges, environmental challenges, and customer challenges influence SC challenges and all the challenges affect organizational performance. The data were collected from organized non-livestock retail players operating in north India. All the results are validated using rigorous statistical analysis.
Content Based Video Retrieval using Mobile Agent
Sheenam Malhotra,Rajwinder Singh,Sangeeta Gupta,C. Rama Krishna
International Journal of Artificial Intelligence & Knowledge Discovery , 2011,
Abstract: With the evolution of technology, large amount of information is available in heterogeneous formats and need to be retrieved efficiently in distributed environment. Content based multimedia retrieval system (CBMR) is a common approach based on automatic retrieval process, rather than traditional keyword-based technique, which was very time-consuming. The growing usage of network interrupts the working of network models and puts tremendous pressure on bandwidth requirements and network management. Any form of distribution brings with it the management overhead and the burden of dealing with it lies with the user. Finding and managing information over the network is one of the complex and time-consuming process. Mobile agent is an emerging technology of distributed computing that can overcome the barriers posed by network congestion and helps in getting response to a query. It acts on behalf of a user and fits well in the low-bandwidth network environments. Mobile agents are used for managing the network traffic, improving reliability, providing fault tolerance and also for multimedia retrieval. Research is being carried on the use of mobile agents for image retrieval. In this paper, mobile agent based architecture for content based video retrieval system is implemented. It focuses on searching and retrieving video files and maintaining video metadata database. The video comparison is based on calculation of feature vector. The paper shows the results of comparison of two videos by calculating the feature vector for every frame and comparing them frame by frame. After comparison the similar videos are retrieved from the remote machine and results of comparison are stored in the database on the source machine.
Concurrency Control for Multilevel Secure Databases
Navdeep Kaur,Rajwinder Singh,Manoj Misra,A. K. Sarje
International Journal of Network Security , 2009,
Abstract: A multilevel secure (MLS) database is intended to protect classified information from unauthorized users based on the classification of the data and the clearances of the users. The concurrency control requirements for transaction processing in multilevel secure database management systems (MLS/DBMSs) are different from those in conventional transaction processing systems. In MLS/DBMSs, coordination of transactions at different security levels is needed to avoid both covert channels and the starvation of high security level transactions. In this paper we outline the transaction processing requirements in MLS/DBMSs, and survey the mechanisms proposed to address these requirements and propose a new secure multiversion concurrency control protocol. We also investigate the relative performance of existing secure concurrency control protocols while varying workloads.
RNA Viruses in Hymenopteran Pollinators: Evidence of Inter-Taxa Virus Transmission via Pollen and Potential Impact on Non-Apis Hymenopteran Species

Abstract: Although overall pollinator populations have declined over the last couple of decades, the honey bee (Apis mellifera) malady, colony collapse disorder (CCD), has caused major concern in the agricultural community. Among honey bee pathogens, RNA viruses are emerging as a serious threat and are suspected as major contributors to CCD. Recent detection of these viral species in bumble bees suggests a possible wider environmental spread of these viruses with potential broader impact. It is therefore vital to study the ecology and epidemiology of these viruses in the hymenopteran pollinator community as a whole. We studied the viral distribution in honey bees, in their pollen loads, and in other non-Apis hymenopteran pollinators collected from flowering plants in Pennsylvania, New York, and Illinois in the United States. Viruses in the samples were detected using reverse transcriptase-PCR and confirmed by sequencing. For the first time, we report the molecular detection of picorna-like RNA viruses (deformed wing virus, sacbrood virus and black queen cell virus) in pollen pellets collected directly from forager bees. Pollen pellets from several uninfected forager bees were detected with virus, indicating that pollen itself may harbor viruses. The viruses in the pollen and honey stored in the hive were demonstrated to be infective, with the queen becoming infected and laying infected eggs after these virus-contaminated foods were given to virus-free colonies. These viruses were detected in eleven other non-Apis hymenopteran species, ranging from many solitary bees to bumble bees and wasps. This finding further expands the viral host range and implies a possible deeper impact on the health of our ecosystem. Phylogenetic analyses support that these viruses are disseminating freely among the pollinators via the flower pollen itself. Notably, in cases where honey bee apiaries affected by CCD harbored honey bees with Israeli Acute Paralysis virus (IAPV), nearby non-Apis hymenopteran pollinators also had IAPV, while those near apiaries without IAPV did not. In containment greenhouse experiments, IAPV moved from infected honey bees to bumble bees and from infected bumble bees to honey bees within a week, demonstrating that the viruses could be transmitted from one species to another. This study adds to our present understanding of virus epidemiology and may help explain bee disease patterns and pollinator population decline in general.
Very High Throughput Electrical Cell Lysis and Extraction of Intracellular Compounds Using 3D Carbon Electrodes in Lab-on-a-Chip Devices
Guillaume Mernier,Rodrigo Martinez-Duarte,Rajwinder Lehal,Freddy Radtke,Philippe Renaud
Micromachines , 2012, DOI: 10.3390/mi3030574
Abstract: Here we present an electrical lysis throughput of 600 microliters per minute at high cell density (10 8 yeast cells per ml) with 90% efficiency, thus improving the current common throughput of one microliter per minute. We also demonstrate the extraction of intracellular luciferase from mammalian cells with efficiency comparable to off-chip bulk chemical lysis. The goal of this work is to develop a sample preparation module that can act as a stand-alone device or be integrated to other functions already demonstrated in miniaturized devices, including sorting and analysis, towards a true lab-on-a-chip.
How I do it: transapical cannulation for acute type-A aortic dissection
Andrzej W Sosnowski, Rajwinder S Jutley, Nicola Masala, Christos Alexiou, Justiaan Swanevelder
Journal of Cardiothoracic Surgery , 2008, DOI: 10.1186/1749-8090-3-4
Abstract: Femoral artery cannulation with retrograde perfusion is the most common method but because of the risk of malperfusion of vital organs and atheroembolism related to it different sites such as the axillary artery, the innominate artery and the aortic arch are used. Cannulation of these sites is not without risks of atheroembolism, neurovascular complications and can be time consuming. Another yet to be popularised option is the transapical aortic cannulation (TAC) described in this article. TAC consists of the insertion of the arterial cannula through the apex of the left ventricle and the aortic valve to lie in the sinus of Valsalva. Trans-oesophageal guidance is necessary to ensure correct placement of the cannula.TAC is an excellent method of establishing cardiopulmonary bypass as it is quick, provides a more physiological method of delivering antegrade arterial flow and is the only method to assure perfusion of the true lumen.Aortic dissection is the most frequently diagnosed lethal disease of the aorta. Half of all patients diagnosed with acute type-A aortic dissection die within 48 hours of presentation. The principal aim of surgery in type-A aortic dissection is to prevent aortic rupture and further dissection into the aortic valve and coronary ostia.The most popular approach to establishing arterial return for cardiopulmonary bypass (CPB) in type-A aortic dissection is femoral cannulation with retrograde perfusion of the aorta. Although this technique has been used since 1950s, it is not without its problems. The retrograde perfusion of the aorta has a potential risk of cerebral embolisation of atheromatous debris and extension of the dissection flap. The technique may also result in intraoperative malperfusion of aortic branch vessels. The alternative sites for arterial cannulation which also allow antergrade perfusion of the aorta include the aortic arch, axillary artery and the innominate artery [1,2].However, these approaches are not strictly antegrade as
Analysis of Vortex Motion in Porous Media  [PDF]
Beant Singh, Chanpreet Singh
Journal of Electronics Cooling and Thermal Control (JECTC) , 2012, DOI: 10.4236/jectc.2012.22003
Abstract: In vortex motion fluid moves in curve path and the stream lines are curved. When the fluid flows between curved stream line, the centrifugal forces are setup which is counter balanced by pressure forces acting in the radial direction. The vortex motion has two types of curved motion. The first type called free vortex type, the fluid moves due to its own natural effect but energy is not added to fluid when moving in curved path. The second type called forced vortex, in which energy is added to fluid. A two dimensional steady laminar free convective flow of viscous incompressible flow in porous media voids is considered. In this paper the motion of fluid is studied while moving in the porous media. It is studied that the motion of the fluid in the porous media is vortex motion at the low Reynolds’s number, where the motion is laminar motion and the fluid obeys the laws of vortex motion.
