By developing an interactive open source-based WebGIS information portal on war and peace for the online services of the Federal Agency for Civic Education, the Bonn International Center for Conversion (BICC) translates scientific knowledge into easily understandable and subsumable up-to-date information for the general public and young scholars. By aggregating globally scattered data and infor...

Recommender systems are being used by an ever-increasing number of E-commerce sites to help consumers find products to purchase. What started as a novelty has turned into a serious business tool. Recommender systems use product knowledge – either hand-coded knowledge provided by experts or “mined” knowledge learned from the behavior of consumers – to guide consumers through the often-overwhelmi...

E-science promises to allow globally-distributed collaboration and access to scientific research via computer networks, but e-science development is already encountering difficulty over the intellectual property rights associated with data and networked collaborative activity. The proprietary nature of intellectual property is generally problematic in the practice of science, but such difficult...

Price return and P/E are two important factors for a lot of investors based on the latest studies by researchers in Tehran Stock market; however, it is expected that the price and the variation of that affect the return and the P/E of any given market as a complicated system. The Bohmian quantum mechanics used referring to the time correlation of return and P/E of the stock market under conside...

Advances in e-commerce have resulted in significant progress towards strategies, requirements, and development of e-commerce applications. However, nearly all e-commerce applications envisioned and developed so far assume fixed or stationary users with wired infrastructure.

In the current context, characterized by a sort of ‘open innovation’, spin-offs phenomenon represents an innovative approach to support technological knowledge transfer and innovation processes from research organizations to industrial world. Furthermore, spin-offs could be considered an innovative strategy to follow up the results obtained within collaborative R&D (Research and Development) pr...

A6s t~ac t A flyback dc-dc converter is obtained from t h e conventional buck-boost converter by replacing t h e inductor with an isolation transformer. A transformer in the flyback converter is used to achieve a d c isolation between t h e input and the o u t p u t of t h e converter. This paper presents dc and small-signal circuit models for t h e flyback converter for continuous conduction m...

Over the past decade, there has been a lot of work in developing middleware for integrating and automating enterprise business processes. Today, with the growth in e-commerce and the blurring of enterprise boundaries, there is renewed interest in business process coordination, especially for inter-organizational processes. This paper provides a historical perspective on technologies for intraan...

The term 'social media' refers to a cluster of applications and online services that support human interaction and content broadcasting and sharing. Current services are isolated islands or 'walled gardens', and are based on a business model that is highly exploitative of individuals and their data. An alternative, consumer-oriented approach is feasible, involving open architecture, inter-opera...
