Assessing the Need for PhD in Information Studies: Stakeholder Insights  [PDF]
Sajjadur Rehman, Abdus Sattar Chaudhry, Hessah O. Alasousi
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105322
Seeking insights of stakeholders is an important element of the needs assessment process for starting a doctoral program. This paper reports a study that reviewed the perspectives of stakeholders with regard to a PhD in information studies. Feedback from major stakeholders was sought using a combination of qualitative and quantitative methods: a web-based survey of 180 relevant stakeholders (including current master students, alumni of the department, faculty members and working information professionals) followed by a focus group discussion with 7 faculty members from Kuwait University and Public Authority for Training and Education. Findings showed that there was a need for starting a PhD program in information studies at Kuwait University. Data also provided important insights about the structure of the proposed program, its content, areas of coursework and specializations. Results of the study might be useful for developing a PhD program in other universities. The findings are also expected to provide guidelines for conducting needs assessment for doctoral programs in information studies.
Performance Investigation on Two-Classes of Manet Routing Protocols Across Various Mobility Models With QoS Constraints
Foez Ahmed,Muhammad Sajjadur Rahim
International Journal of Computer Networks & Communications , 2011,
Abstract: An ad-hoc network is an aggregation of wireless nodes forming a provisional network without anyestablished infrastructure. To facilitate communication within such network, a routing protocol is used todiscover and setup routes between nodes. The goal of the routing protocol is to have an efficient routeestablishment between a pair of nodes, so that messages can be delivered in a timely manner. Thisresearch investigates the effects of various mobility models on QoS metrics for two prominent proactiveand reactive MANET routing protocols - Fisheye State Routing (FSR) protocol and Ad-hoc On-demandDistance Vector, from Uppsala University (AODVUU) respectively. Performance is measured by thevarying number of traffic sources, number of nodes, host velocity, and data sending rate. These twoprotocols are simulated and compared under different mobility models namely Random WaypointMobility Model, Manhattan Grid Mobility Model and Reference Point Group Mobility Model. Theperformance metrics that are used to evaluate the performance of the routing protocols are Packetdelivery ratio (PDR), Average latency of data packets, Network control overhead (NCO) and Throughput.Experimental results reveal that. on-demand routing protocol AODVUU is more sensitive to the speed ofmobile nodes than the proactive routing protocol FSR. Due to its proactive nature, FSR can be used inbandwidth and resource critical environment. On the other hand scalability of AODVUU is limited forhigh-speed network. However, in case of higher data rates AODVUU always performs better in terms ofPDR under all three mobility models.
Jovian Problem: Performance of Some High-Order Numerical Integrators  [PDF]

American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.33028

N-body simulations of the Sun, the planets, and small celestial bodies are frequently used to model the evolution of the Solar System. Large numbers of numerical integrators for performing such simulations have been developed and used; see, for example, [1,2]. The primary objective of this paper is to analyse and compare the efficiency and the error growth for different numerical integrators. Throughout the paper, the error growth is examined in terms of the global errors in the positions and velocities, and the relative errors in the energy and angular momentum of the system. We performed numerical experiments for the different integrators applied to the Jovian problem over a long interval of duration, as long as one million years, with the local error tolerance ranging from 10-16 to 10-18.

Accuracy and Computational Cost of Interpolation Schemes While Performing N-Body Simulations  [PDF]

American Journal of Computational Mathematics (AJCM) , 2014, DOI: 10.4236/ajcm.2014.45037
Abstract: The continuous approximations play a vital role in N-body simulations. We constructed three different types, namely, one-step (cubic and quintic Hermite), two-step, and three-step Hermite interpolation schemes. The continuous approximations obtained by Hermite interpolation schemes and interpolants for ODEX2 and ERKN integrators are discussed in this paper. The primary focus of this paper is to measure the accuracy and computational cost of different types of interpolation schemes for a variety of gravitational problems. The gravitational problems consist of Kepler’s two-body problem and the more realistic problem involving the Sun and four gas-giants—Jupiter, Saturn, Uranus, and Neptune. The numerical experiments are performed for the different integrators together with one-step, two-step, and three-step Hermite interpolation schemes, as well as the interpolants.
Safety Management in a Manufacturing Company: Six Sigma Approach  [PDF]

Engineering (ENG) , 2012, DOI: 10.4236/eng.2012.47053
Abstract: The manufacturing company under consideration recorded the high accident rates for last few years. These accidents cause the organization the heavy man-day loss, the production loss and heavy costs of insurance. The objective of health and safety department at the manufacturing company was to set and improve accidents prevention system. The paper presents how does the six-sigma technique will help to evaluate the safety and environmental hazards in performance of organizations? It is observed that the study helped the management to measure, analyze and improve overall safety plan to protect the life and health of the employees.
Effect of cadmium on the growth of tomato

Biology and Medicine , 2011,
Abstract: The present experiment was conducted to test the effect of cadmium (Cd) on the vegetative and reproductivegrowth of Lycopersicon esculentum cv. Navodaya (tomato). The selected plant species was treated 4 times with10, 20, 30 and 40 μg cadmium. The plant was treated twice at pre-flowering stage at 10 days interval and twice atpost-flowering stage. Almost all selected growth parameters were sensitive to all or at least high doses of Cd. Inthe present study, the total chlorophyll content increased in the plants treated with Cd. The plant biomassdecreased significantly on treatment with higher doses of Cd. The leaf number and leaf area was negativelycorrelated with the concentration of cadmium.
E-Marketing Practices: An Empirical Investigation of HSBC and Jammu & Kashmir Bank

International Journal of Knowledge and Research in Management and E-Commerce , 2012,
Abstract: e-Marketing has a lot of benefits which add value to customers’ satisfaction in terms of better quality of service offerings the banks gain more competitive advantage over other competitors. The present empirical study focuses on identifying the key factors of e-marketing practices that have an adverse effect on the customers’ satisfaction. In this paper, two banks are taken under study i.e. HSBC (HongKong and Shanghai Banking Corporation) and J & K (Jammu & Kashmir Bank). In this paper respondents are selected through Random sampling; while the survey Instrument was a developed Questionnaire comprising questions based on Likert scale. The Likert scale has a 5 point scale (indicating 1 = Strongly Disagree, 2 = Disagree, 3 = Neutral , 4 = Agree and 5 = Strongly Agree) divided into two (2) sections: personal details and customers’ opinion towards e-marketing through the medium of Internet banking, mobile banking and ATM (Automated Teller Machine). The instrument contained 12 items and was administered to about 200 respondents, while 157 completed and returned their Questionnaire. The statistical techniques used for the analysis were Independent sample Test. The Independent sample test revealed that the customer satisfaction of e–marketing practice offered by HSBC and J & K banks have significant influence on their customers at 95%. In this study the main focus is on the e-marketing practices which are prevailing in both the banks that is Internet Banking, Mobile Banking and ATM (Automated Teller Machine). Results of independent sample t-test shows that Internet Banking, Mobile Banking and ATM practices were most important factors in customer satisfaction in both the banks.
