Particle Swarm Optimization Model for Dynamic Supply Chain Inventory Optimization involving Lead Time
Radhakrishnan Perumalsamy, Jeyanthi Natarajan
Abstract
Efficient and effective management of inventory throughout the supply chain significantly improves the ultimate service provided to the customer. Efficient inventory management is a complex process which entails the management of the inventory in the entire supply chain and getting the final solution as optimal leading to minimum total supply chain cost. The dynamic nature of the excess stock level and shortage level over all the periods is a serious issue when implementation is considered. In addition, the complexity of the problem increases when more number of distribution centers and agents are involved. Moreover, the supply chain cost increases because of the influence of lead times for supplying the stocks . A better optimization methodology would consider all these factors in the prediction of the optimal stock levels to be maintained in order to minimize the total supply chain cost. In this paper, an optimization methodology is proposed that utilizes the Particle Swarm Optimization algorithm, one of the best optimization algorithms to overcome the impasse in maintaining the optimal stock levels in each member of the supply chain.

Optimization of a Multiphase Emulsion Mixer
K.F.K. Oyedeko, Olusegun A. Sodeinde and Ugba Eborieme
Abstract
Mixing is a very vital operation in the chemical and allied industries because the attainment of homogeneity revolves round Mixing. However, the mixing processes are influenced by many factors which include; types of impeller, vessel geometry, nature of reactants, speed of agitation, mixing time, among others. In this article , the significance of impellers in a mixing system to actualize a uniformity/homogeneity in a multiphase emulsion is investigated. This involves construction of a laboratory mixer, two different impellers, and performance of experiment and simulation of results. Running of study on laminar flow. The three bladed impeller produced a better correlation of the experimental results with simulated results. The three bladed form a more linear relationship between the two variables of temperature versus mixing time and concentration of mixture versus blending time. The two bladed required power than the three bladed to achieve the same results of mixing. Simulated result revealed that the three bladed impeller has the higher efficiency and optimally better in contributing to maintain a homogeneous solution than the two bladed impeller for a cylindrical mechanical agitated reactor.

Adsorption of Textile Wastes Containing Methylene Blue & Congo Red using Activated Carbon Produced from Coconut Shell
Olusegun Sodeinde and Ugba Eboreime
Abstract
The use of low-cost, locally available, highly efficient, and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from waste water. This study investigated the potential use of activated carbon produced from coconut-shell for the removal of two dyes viz: Methylene blue and Congo red from textile effluent obtained from Nichemtex Industries Ltd (NCTX) at Ikorodu, Lagos State. The coconut shells were carbonated and used to produce activated carbon using Zinc Chloride as the activating agent. The effects of contact time, pH, adsorbent dose, temperature were investigated for different particle sizes of 1nm, 50nm, and 500nm mesh-sizes for the removal of both dyes (i.e Methylene blue and Congo red) respectively, and the optimal experimental conditions were ascertained. The results showed that as the amount of the adsorbent increased, the degree of adsorption increased accordingly and equilibrium adsorption was attained in 2hrs (i.e 120mins). The optimum pH for the adsorption of dyes were 8.0, 6.0, and 4.0 for 1nm, 50nm, and 500nm mesh-sizes respectively. Maximum dye was sequestered within 30mins of the start of each experiment.

Work Life Balance Retention (WLBR) Model – A Weapon to Retain Hi-Tech Employees
Neha Bajpai, Asha Prasad and P. N. Pandey
Abstract
This paper presents an integrated model of retaining IT professionals in the organization. Nowadays, the competition among the hi-tech companies is increasingly focuses on the competition in hi-tech employees. In today’s fast paced society and an intensely competitive environment, the Human Resource Managers are seeking options to improve employee morale, retain hi-tech employees with valuable technical knowledge and keep pace with workplace trends. If the HR Managers of IT firms will not be careful, it will result in the outflow of innovative and technical employees who are regarded as the core of human resources for the organizations. Therefore, the outflow of the hi-tech employees counts a lot to the organizations and they examine the means of talent retention. This paper emphasizes on an important weapon in the form of Work Life Balance Retention (WLBR) Model to retain the hi-tech employees through encouraging Work Life Balance in the organization. WLBR Model reveals that work-life balance is both important for the organization and for its employees particularly in current dynamic organizational scenarios. It helps the organization to improve productivity, efficiency, competitiveness, morale and hence gain a competitive edge. Similarly employees are benefited from work-life balance initiatives through increased motivation to work, enhanced satisfaction, empowerment, commitment and ultimately retention in the organization.

Role of Contextual Factors in using eLearning Systems for Higher Education in Developing Countries
Abdul Sattar Khan, Allah Nawaz
Abstract
The same basic computing facilities are available in most of the Asian countries like Pakistan; however it is never possible to attain the same outputs from digital systems working either in public or private sector. This difference emerges from the impacts of contextual factors which can make or break the objectives of a digital move in any sector including higher education. There are personal, organizational, and social contexts which create a particular culture or lifestyle of the inhabitants. If these contexts are in favor, the digital revolution happens in a spell of time but if context is either neutral or rival then the developers and users of eLearning systems have to take account of all the possible influences emerging from any context while developing, implementing and using the new digital devices in a particular work environment. This paper extracts evidence from the literature to uphold the arguments tabled in this abstract.
