In the competitive market of B2B e-commerce website, as customer switching cost and network externality could prevent customers to switch to later entrant, the earlier entrant has the advantage to build and retain its market share. However, the declining cost of information technology (IT) over time provides the later entrant a cost advantage. In order to maintain competitive advantage, what sh...

For mobile agents roaming in a network, location management strategies still represent a current research issue, for contacting and communicating with these agents. The cost of a location management strategy mainly depends on the cost of location search and update. In order to save this cost, mobile agents should not update their location every time they change the host. This paper discusses th...

we inverse the surface gravity data to recover subsurface 3d density distribution with two strategy. in the first strategy, we assumed wide density model bound for inverting gravity data and in the second strategy, the inversion procedure have been carried out by limited bound density. wediscretize the earth model into rectangular cells of constant andunidentified density. the number of cells i...

Customer Relationship Management (CRM) is getting more and more a key strategy for companies big and small. Customer care strategy and CRM software go hand in hand. In particular SME’s need a CRM software that easily adapts to their customer care needs while still being low cost.

A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...

The objective of this study was to determine how effective angiotensin-converting enzymes (ACEs) must be in preventing diabetic nephropathy to warrant routine administration to insulin-dependent diabetic patients. A Markov model was used to compare three strategies designed to prevent the development of end-stage renal disease in insulin-dependent diabetic patients. Strategy I, screening for mi...

In construction management the definition of a robust schedule is often more important than finding a time and cost efficient schedule. In nearly every construction project the planned schedule must be continually adapted due to disruptions. Therefore, it is imperative that a robust schedule should be generated regarding the different project objectives. In the context of planning and schedulin...
