Mathematical modeling is very important when experimental settings with human subjects are restricted to thermal limits necessary to protect the individual. The predicted heat strain (PHS) model has been published AS ISO 7933 for about six years. It describes a method for predicting the sweat rate and internal core temperature that the human body will develop in response to the working conditions.

Purpose of this paper The current RFID technology literature considers several issues. However, the implementation models and guidelines available in this literature are quite fragmented and lack certain elements. The purpose of this paper is thus to put all relevant elements together and discuss them within a comprehensive framework for designing logistical RFID systems. Design/methodology/appro

The year 2007 was an extraordinary year for the US Patent System. In a response to far reaching proposals for significant changes in substantive and procedural patent law the House of Representatives adopted the Patent Reform Act in September and the debates were heating up again. Moreover, the U.S. Supreme Court turned its attention to patent issues delivering three major patent judgments and gra

Over the past few years, we have witnessed a growing popularity of new wireless architectures such as 3G, Wi-Fi and Wi-Max due to the increase in demand for wireless Internet access. The all-IP based future mobile and wireless network model is expected to be the most dominant architecture for QoS provisioning in next-generation wireless networks, mainly due to its scalability and capability of int

In the debate on how to make democracy strong against terrorism, it has been suggested that the Western democracies need new protective measures. This paper argues that, far from protecting democracy, such measures may in fact undermine the very values and virtues that make democracy possible. Information freedom, the right to due process and the protection of privacy are all fundamental for the

This paper presents the results of a pilot study prepared for a larger research project entitled ‘Media practices in contemporary feminist movements in and across Europe’ which examines how feminist groups and networks in Northern Europe (Sweden, Denmark) and Southern Europe (Spain and Portugal) are engaging online media in their struggle for gender equality and transformative social change. As

In this paper water and salt mass balances for the Dead Sea were modeled. Precipitation, evaporation, river discharges, ground water flows, input/output from potash companies and salt production, and brine discharge were included in the models. The mixing time in the Dead Sea was modeled using a single-layer (well-mixed) a two-layer (stratified) system. Using the single-layer approach the water le
