In this research, approaches to e-business in the maritime sector in Egypt were examined. The organizational strategic view, the evolution of ebusiness in terms of an analysis of business functions, and the consideration of some stage models of the evolution were explored. The research method combines a case study approach with the use of process modeling tools and ebusiness evolution stage model. These tools were applied to Alexandria, Egypt's largest, long established and Government-run port. The process architecture modeling method used was Ould's Riva method. In this study, possibilities for achieving higher stages of e-business in Alexandria port were reexamined using a combination of three methods: Ould's improvement diagnosis; Davenport's analysis of information technology; and Earl's six stage model of e- business development. Adherence of the top management to the port's strategic view is a key success factor to the transformation and improvement of the organizational processes, including process automation. © 2012 IEEE.

Text summarization solves the problem of extracting important information from huge amount of text data. There are various methods in the literature that aim to find out well-formed summaries. One of the most commonly used methods is the Latent Semantic Analysis (LSA). In this paper, different LSA based summarization algorithms are explained and two new LSA based summarization algorithms are proposed. The algorithms are evaluated on Turkish documents, and their performances are compared using their ROUGE-L scores. One of our algorithms produces the best scores. Source

In this paper, two dimensional (2-D) direction-of-arrival (DOA) estimation problem in case of unknown mutual coupling and multipath signals is investigated for antenna arrays. A new technique is proposed which uses a special array structure consisting of parallel uniform linear array (PULA). PULA structure is complemented with auxiliary antennas in order to have a structured mutual coupling matrix (MCM). MCM has a symmetric banded Toeplitz structure which allows the application of the ESPRIT algorithm for 2-D paired DOA estimation. The advantage of the PULA structure is exploited by dividing it into overlapping linear sub-arrays (triplets) and spatial smoothing is employed to mitigate multipath signals. Closed form expressions are presented for search-free, paired and unambiguous 2-D DOA estimation. Two algorithms PULA-1 and PULA-2 are proposed to effectively solve the problem. Several simulations are done and the accuracy of the proposed solution is shown. © 2014, Springer Science+Business Media New York. Source

Building the skills for doing, managing and delivering health research is essential for every country's development. Yet human resources for health research (HRHR) are seldom considered in Africa and elsewhere. Africa's health research capacity has grown considerably, with potential to increase this growth. However, a systemic way of defining, co-ordinating and growing the HRHR needed to support health systems development is missing. Reviewing the status of HRHR in Africa, we assert that it consists of unco-ordinated, small-scale activities, primarily driven from outside Africa. We present examples of ongoing HRHR capacity building initiatives in Africa. There is no overarching framework, strategy or body for African countries to optimise research support and capacity in HRHR. A simple model is presented to help countries plan and strategise for a comprehensive approach to research capacity strengthening. Everyone engaged with global, regional and national research for health enterprises must proactively address human resource planning for health research in Africa. Unless this is made explicit in global and national agendas, Africa will remain only an interested spectator in the decisions, prioritisation, funding allocations, conduct and interpretation, and in the institutional, economic and social benefits of health research, rather than owning and driving its own health research agendas.

Optimization and control of the microstructure is vital for improving performance and service life of the steel components. Development of non-destructive techniques for microstructure characterization has been a challenging task for many years. Magnetic Barkhausen Noise method is a non-destructive evaluation technique with high potential for characterization of steels. This paper summarizes the related studies performed at METU. © RILEM 2013. Source
