Many developing countries are experiencing procurement problems. Is e-governance the solution? A discussion paper on Zimbabwe

RudoMatachi and Dr FaraiChoga,[DOI: 10.24214/jecet.B.8.1. 00107.]

Many developing countries are experiencing procurement problems. The problems include: lack of enforcement of rules and regulations, no electronic infrastructure, high cost of technology, in some cases lack of legal framework, lack of technical expertise, lack of e-procurement knowledge and above all lack of e-governance. Through e-governance e-procurement can bring a lot of benefits that include: cost reduction, visibility of procurement process, time savings, improved productivity and minimised corruption. To resolve procurement challenges e-governance must be in place as e-procurement is part of this process

Improved Workflow Scheduling Using Convex Optimization With Grey Wolf Approach

Divya Saini, Varun Jasuja, Dr. Rajesh Kumar Singh,[DOI: 10.24214/jecet.B.7.4.40109.]

Workflow scheduling in scientific computing systems is one of the most challenging problems that focuses on satisfying user-defined quality of service requirements while minimizing the workflow execution cost. So to reduce the cost, cloud environment, has been deployed in cloud environment, resources will increase but its utilization is another challenge. To maintain & utilize resources in the cloud computing scheduling mechanism is needed. Many algorithms and protocols are used to manage the parallel jobs and resources which are used to enhance the performance of the CPU in the cloud environment. This work Particles swarm Optimization (PSO) and Grey Wolf Optimization (GWO) are used for effective scheduling. This work is based on the optimization of Total execution time and total execution cost. The results of the proposed approach are found to be effective in compare to existing methods. Intelligence optimization Particle Swarm optimization is used which is initialized by Pareto distribution. GWO is used to converge the decision of Virtual Machine (VM) migration by
its convergence to minimize cost and time as illustrated by Total execution time (TET) and Total execution cost (TEC) .It is concluded that GWO performs better in compare to existing BAT algorithm.

Study of Pharmaceutical Solid dosage forms using Invasive and Non Invasive Techniques: A Review

Rohit S. Gupta, Ratnadeep R. Deshmukh, Priyanka U. Randive, Akshay V. Kshirsagar, Jaypalsing N. Kayte

Pharmaceutical solid dosage forms for oral use are the most common pharmaceutical formulation types worldwide. They are complex multicomponent system that may be available in many diverse structures such as powders, granule, compressed tablet, chewable tablet and capsules. To study the pharmaceutical solid dosage forms is important aspect in current era. In this paper we discussed various methods that are used for analyze the pharmaceutical solid dosage forms, Identification of the contents from solid dosage forms, determined the structure of chemical compounds used in the formulation of pharmaceutical product.

Adoption of e-passport processing system in Zimbabwe (2009 – 2017)

Mavis Mugabe and Dr Farai Choga

The e-passport applicants and system users were the respondents on the successful adoption of e-passport system technologies. The research used the Technology Acceptance Model (TAM) as a theoretical framework. Hypotheses derived from the framework were used to test acceptance of Zimbabwean e-passport system. The study was premised on the descriptive correlational research design. The participants answered questions administered through both interviews and close-ended questionnaires. The researchers used quantitative methodology. A total of 50 questionnaires were distributed to various e-passport system users which comprised of passport applicants and passport staff. Only 37 questionnaires were filled and returned. This gave a 74% response rate. The findings of this study showed that the ICT network had positively affected the perceived usefulness of the e-passport system. Internet skills and computer self-efficacy had a significant effect on the perceived ease of use of the e-passport systems and perceived usefulness positively influenced users’ attitude towards using e-passport system. The pperceived ease of use positively affected attitude towards using e-passport application system. The attitude towards using e-passport system did not positively influence users’ behavioural intention to use the system. Behavioural intentions had a significant effect on actual e-passport system usage. The study recommended that there was a need to increase the external factors such as network connectivity to ensure effective connection to the production centre from the service centre. The e-passport applicants and passport office staff system users should be trained on the system to promote system usage.

Model-View-Controller Framework for Postgraduate Admission and Inter-University Academic Records

Balogun A. O; Dr.Oye, N. D.

Web applications have become the primary source of information and transactions over the internet and this has led to high demand for continuously evolving web applications. University administrators and other stake holders depend on them for many of their operations including postgraduate admissions. Even though many institutions have independently developed systems to handle postgraduate admission processing, there is need for the development of a system that will serve all Nigerian institutions in order to securely and seamlessly integrate all the various aspects involved in the domain. Nowadays there are different forms and technologies for implementing web applications without much concern for their architectural model. Without a good and stable architecture those applications may fail during their operations. This study therefore focuses on an architecture that conforms to current best practices in creating web solutions. The Model-View-Controller (MVC) software engineering architecture has been widely embraced as an approach for developing web-based systems that contain a server-side programming component, particularly for those requiring database access. Of the various possible methodologies for carrying out this study, the researcher made particular choices: Use Case texts, Use Case diagram, Domain class diagram, design class diagram (DCD) and ASP.Net implementation. Database design was done using T-SQL and Local DB feature in Microsoft Visual Studio 2012. Programming language was C# and the design was implemented using the Internet Template. The implemented design was tested and the results are shown. This study has been able to provide an object oriented analysis and design (OOAD) for inter-university postgraduate admission and academic records domain using UML artifacts. Suggested further studies include expanding the framework to include other forms of postgraduate admissions and incorporation of interactive multimedia
