This paper describes the new GNSS data and product services that have been developed within context of EPOS (European Plate Observing System) European Research Infrastructure Consortium (ERIC), which is part Strategy Forum on Infrastructures. These services, optimized for Solid Earth research applications, endeavour to harmonise, standardise Global Navigation Satellite System (GNSS) collection ...

Openness and interdisciplinarity in research data are among the challenges that frequently discussed context of changing scientific scholarly practices. Gradually, visions open widely shared being reconciled with complex realities stem from disciplinary differences cultures. In this paper we discuss through as a way to create environments more flexible and, result, amenable change. We report ou...

this paper investigates the effects of advertising, profitability, concentration and research & development on the market share of iranian great food and beverage industries during the period of 2000-2011. for this purpose, we used the more than 50 employee's statistics of industrial 4- digit firms and panel data technique for estimating the model. the main results of this paper reveal that, th...

This paper reports preliminary findings from the National Hospital Rate-Setting Study regarding the effects of State prospective reimbursement (PR) programs on measures of payroll costs and employment in hospitals. PR effects were estimated through reduced-form equations, using American Hospital Association Annual Survey data on over 2,700 hospitals from 1969 through 1978. These tests suggest t...

Philosophers of science increasingly recognize the importance of idealization: the intentional introduction of distortion into scientific theories. Yet this recognition has not yielded consensus about the nature of idealization. e literature of the past thirty years contains disparate characterizations and justifications, but little evidence of convergence towards a common position. Despite th...

This report considers the problems of scheduling transmissions in broadcast environments, including, wireless environments. Issues that affect the design of fair scheduling algorithms, and several alternative approaches to implementing fair scheduling in single-hop and multi-hop environments are identified.

Providing delay guarantees to time-sensitive traffic in wireless multimedia networks is a challenging issue. This is due to the time-varying link capacities and the variety of real-time applications expected to be handled by such networks. We propose and evaluate the performance of a channel-aware scheduling discipline and a set of policies that are capable of providing such delay guarantees in...
