An Interactive Web-based Application as Educational Tool for SCM Course by Using FOSS

This paper presents the application of free/open source software (FOSS) for teaching and learning one specific topic in Supply Chain Management (SCM) course. In the last few years, there is abundant FOSS for educational tools. However, educator still faces problems to implement such an education FOSS for improving the quality of education i.e. customizing of software function, developing of a specific educational media, and illustrating of a course content. The purpose of this research is to design an educational tool for increasing efficiency in conveying subject matter especially distribution problem. It has a module of real distribution problem in commodity paddy was captured. We crated an interactive Web-based application by using WSDL, PHP and My SQL, and SOAP. The result of the research will be able to improve the pedagogic approach for learning of SCM course. Keywords: Educational tool, FOSS, interactive media, SCM course

JSE Matching engine simulator

A dissertation submitted in fulfilment of the requirements of the degree of Master of Science in the School of Computer Science and Applied Mathematics. June 11, 2017The Johannesburg Stock Exchange (JSE) started High Frequency Trading when their matching engine moved from London to Johannesburg in 2012. The study of market microstructure at the JSE is not possible without access to their matching engine. This dissertation investigates the challenges of studying market microstructure and describes the design and implementation of an open source matching engine. CoinTossX was developed as an open source low latency high throughput stock exchange. The software was developed in Java and used open source libraries. The software is tested using an 8-variate mutually-exciting Hawkes process to govern the times of coupled liquidity demand and supply events, while trade and quote prices and volumes are generated consistent with the event type. The testing showed that CoinTossX is able to support multiple clients, stocks and matching algorithms.LG201

Despatches from the Front: Recent Skirmishes Along the Frontiers of Electronic Contracting Law

This Article will provide a short overview of the current efforts in the United States and the European Union to reform contract law to accommodate recent innovations in electronic contracting. Whether changes are needed to current contract law doctrines governing contract formation, effectiveness of contract terms, choice of law and forum provisions, special protections for consumers, and signature and writing requirements, revisions in these areas have all proved controversial. Even in those areas where a consensus may be emerging on whether law reform may be appropriate in some form, consensus is often still lacking with regard to the specific legislation needed to accomplish those reforms. The United States is not the only major arena where such reforms are being debated. The EU is addressing the same problems, but taking a markedly different approach. If the United States and EU commit themselves to divergent approaches to the regulation of electronic contracting, major obstacles will be placed in the paths of businesses hoping to exploit global electronic markets. Businesses may then be forced to design their electronic commerce systems to conform to multiple, incompatible legal standards, or face the prospect of being shut out of major markets for electronic commerce services altogether

Policy Coherence and Coordination for Trade Facilitation: Integrated Border Management, Single-Windows and other Options for Developing Countries

There is now increasing recognition of the critical importance of trade facilitation to further international commerce, accelerate growth, and enhance welfare if not alleviate poverty among trading nations. But there is also increasing appreciation that it is not just attention to the barriers and bottlenecks behind-the-border that are involved in trade facilitation (TF), it also calls for coherence between policies and regulations at the border and inside the border. The unavoidable participation of many government agencies and private stakeholders in border transactions calls for coordination among them towards a harmonized approach to trade facilitation. This paper discusses the need and relevance of policy coherence and coordination to facilitate trade and to what extent some trade facilitation measures (concepts) such as integrated border management and single-windows may be applicable in developing countries to improve both policy coherence and coordination.Trade Faclitation, Border trade, Policy coherence, Economic Integration

SOPA - a self organizing processing and streaming architecture

This paper describes SOPA, a component framework that is an essential part of the lecture recording system E-Chalk. It envisiones a general processing and streaming architecture featuring autonomous assembly of stream processing components. The goal is to provide an easy to use framework where dynamically organized processing graphs are build out of components from various distributed sources. Based on state-of-the-art solutions for component based software development the system simplifies the implementation and the configuration of multimedia streaming applications and associated tools. It supports stream synchronization transparently while extending components are installed on the fly according to the existing requirements that may change at any time
