this paper deals with the problem of user-server assignment in online social network systems. online social network applications such as facebook, twitter, or instagram are built on an infrastructure of servers that enables them to communicate with each other. a key factor that determines the facility of communication between the users and the servers is the expected transmission time (ett). a ...

This paper focuses on the basic principles of information technology (IT) organization within health sciences centers. The paper considers the placement of the leader of the IT effort within the health sciences administrative structure and the organization of the IT unit. A case study of the University of Missouri-Columbia Health Sciences Center demonstrates how a role-based organizational mode...

As the concurrent functional units in media processors increase continuously to meet the performance needs, the required access (i.e. read or write) ports of the centralized register file (RF) multiply rapidly and cannot be efficiently implemented. We propose a novel ring-structure RF, which is composed of register sub-blocks identical to the RF for a single functional unit. Data exchanges amon...

The ability to engineer real wage cuts in centralized labor markets has depended on exchange rate interventions. This paper provides some structure to the question of how a monetary union would a¤ect the connection between bargaining structure and macroeconomic performance. The results indicate that the precautionary saving motive in anticipation of transitory terms of trade shock is signi...ca...

This paper presents a new optimized decentralized controller designmethod for solving the tracking and disturbance rejection problems for large-scale linear time-invariant systems, using only low-order decentralized controllers. To illustrate the type of results which can be obtained using the new optimized decentralized control design method, the control of a large flexible space structure is ...

In the past, foreign borrowing by developing countries was comprised almost entirely of government borrowing. Recently, private firms and individuals in developing countries borrow substantially from foreign lenders. It is not clear whether the observed increase in private sector borrowing leads to overborrowing and frequent defaults by governments in developing countries. In this paper, we dev...

The use of wireless networking technologies has emerged over recent years in many application domains. The area of grids determines a potentially huge application domain, since the typical centralized computing centers require access from anywhere, e.g., from field engineers who are situated in a wireless network domain. Thus, the integration of suitable business views on mobile grids, of grid ...

Objective of centralized repository is to arrange an outsized number of server machines with little apparatus cost while providing high planning facility and bisection width. It is well understand that the present practice where servers are linked by a tree hierarchy of network switches cannot gather these necessities. In this paper, we find out a newest serverinterconnection structure. The Str...

In the current study, a dual-channel supply chain is considered containing one manufacturer and two retailers. It is assumed that the manufacturer and retailers have the same decision powers. A game-theoretic approach is developed to analyze pricing decisions under the centralized and decentralized scenarios. First, the Nash model is established to obtain the equilibrium decisions in the decent...
