Dual map system for navigation and wireless communication

Abstract: A system produces of an empirical map of wireless communication coverage through a process of combining information from individual clients to produce a map which is then shared by all of the clients. The wireless coverage map aids in maintaining a reliable communications link. The empirical map is generated by combining information from a group of mobile wireless users. The group may consist of a fleet of trucks, taxicabs, government service vehicles, or the customers of a wireless service provider. The mobile vehicles must be equipped with a GPS device or be located by other means such as triangulation. While vehicles are moving, the quality of wireless communication, e.g., signal strength or communication continuity, is recorded for each vehicle as a function of positions. The data from all of the vehicles is combined to produce the empirical map. The empirical map may be maintained at a central site and subsets of the map replicated for individual vehicles. The map may then be used to direct mobile users to sites of superior communications reliability, warn mobile users when they are out of the service area or are about to leave the service area, or to regulate data communications automatically to stop and restart communications as a mobile vehicle passes through a gap in coverage.

Resource allocation in a network-based cloud computing environment: design challenges

Abstract: Cloud computing is a utility computing paradigm that has become a solid base for a wide array of enterprise and end-user applications Providers offer varying service portfolios that differ in resource configurations and provided services A comprehensive solution for resource allocation is fundamental to any cloud computing service provider Any resource allocation model has to consider computational resources as well as network resources to accurately reflect practical demands Another aspect that should be considered while provisioning resources is energy consumption This aspect is getting more attention from industrial and government parties Calls for the support of green clouds are gaining momentum With that in mind, resource allocation algorithms aim to accomplish the task of scheduling virtual machines on the servers residing in data centers and consequently scheduling network resources while complying with the problem constraints Several external and internal factors that affect the performance of resource allocation models are introduced in this article These factors are discussed in detail, and research gaps are pointed out Design challenges are discussed with the aim of providing a reference to be used when designing a comprehensive energy-aware resource allocation model for cloud computing data centers

Hybrid Offerings: How Manufacturing Firms Combine Goods and Services Successfully

Abstract: This article examines key success factors for designing and delivering combinations of goods and services (i.e., hybrid offerings) in business markets. Goods manufacturers, unlike pure service providers, find themselves in a unique position to grow revenues through hybrid offerings but must learn how to leverage unique resources and build distinctive capabilities. Using case studies and depth interviews with senior executives in manufacturing companies, the authors develop a resource-capability framework as a basis for research and practice. Executives identify four critical resources: (1) product usage and process data derived from the firm's installed base of physical goods, (2) product development and manufacturing assets, (3) an experienced product sales force and distribution network, and (4) a field service organization. In leveraging these specific resources, successful firms build five critical capabilities: (1) service-related data processing and interpretation capability, (2) execution risk assessment and mitigation capability, (3) design-to-service capability, (4) hybrid offering sales capability, and (5) hybrid offering deployment capability. These capabilities influence manufacturers' positional advantage in two directions: differentiation and cost leadership. The authors propose a new typology of industrial services and discuss how resources and capabilities affect success across categories of hybrid offers.

Transfer of research-based HIV prevention interventions to community service providers: Fidelity and adaptation

Abstract: HIV prevention research interventions usually follow protocols with specific procedures. If a community-delivered intervention uses the same procedures with the same populations as those in the original research, the behavior change effects should be similar. However, community-based providers may not replicate an intervention exactly as it was conducted in the effectiveness study. Adaptation may be needed to better meet the needs of the clients, community, or organization. We propose that interventions can be defined in terms of core elements likely to be responsible for effectiveness. These core elements cannot be changed without fundamentally changing the intervention, whereas other characteristics may be modified without altering effectiveness. HIV prevention researchers and service providers can collaborate to develop interventions that not only are effective but can also be successfully implemented by service organizations. If researchers actively involve service providers and community members in intervention planning, technology transfer goals can be better achieved.

Specifying and measuring quality of service in distributed object systems

Abstract: Distributed applications are difficult to build and maintain and are even more difficult when the applications are distributed over wide-area networks. Distributed Object Computing middleware has emerged to simplify the building of distributed applications by hiding implementation details behind functional interfaces. However, critical applications have non-functional requirements, such as real-time performance, dependability, or security, that are as important as the functional requirements, but are also hidden by the middleware. Because current distributed object middleware doesn't support these aspects of critical applications, application developers often find themselves bypassing the distributed object systems, effectively gaining little or no advantage from the middleware. We have developed Quality Objects (QuO), a framework for including Quality of Service (QoS) in distributed object applications. QuO supports the specification of QoS contracts between clients and service providers, runtime monitoring of contracts, and adaptation to changing system conditions. A crucial aspect of QuO is a suite of Quality Description Languages for describing states of QoS, system elements that need to be monitored to measure the current QoS, and notification and adaptation to trigger when the state of QoS in the system changes. This paper gives a brief overview of QuO and describes the syntax and semantics of CDL, the component of QDL for describing QoS contracts.
