The term "Internet of Things (IoT)" expresses a huge network of smart and connected objects which can interact with other devices without our interposition. Radio frequency identification (RFID) is a great technology and an interesting candidate to provide communications for IoT networks, but numerous security and privacy issues need to be considered. In this paper, we analyze the security and ...

There are some studies to suggest that the effects of life stress on children and adolescents may be similar to those found in adults. Boyce et al. (1977) demonstrated a relationship between life stress and respiratory tract illness, Bedell et al. (1977) using chronically ill children as subjects, found life stress to be correlated with day to day changes in health status. Padilla et al. (1976)...

Introduction There is signifi cant concern regarding the widespread loss of biodiversity and the destructive effects of human activity on the natural environment (Carson 1962; Wilson 2002). Over 500 extinctions of animal species have been recorded since 1600 (Frankham et al. 2002), with this rate signifi cantly increasing over the past 150 years (Primack 1998). Furthermore, the International Un...

5 The quest for methodologies appropriate for evaluating complementary and alternative medicine (CAM) continues to challenge the research community. Two papers in this issue, Sherman et al.’s “Description and Validation of a Noninvasive Placebo Acupuncture Procedure,” (pp. 11–19) and Hawk et al.’s “Issues in Planning a Placebo-Controlled Trial of Manual Methods: Results of a Pilot Study,” (pp. ...

 Using the concept of system signature introduced by Samaniego (1985), Kochar et al. (1999) compared the lifetimes of the systems in which the lifetimes of the components are independent and identically distributed (i.i.d.) random variables. Their results are extended to the systems with exchangeable components by Navarro et al. (2005). This paper gives some alternative proofs to obtain th...

Generation and distribution of electric energy with good reliability and quality is very important in power system operation and control. This is achieved by Automatic Generation Control (AGC). In an interconnected power system, as the load demand varies randomly, the area frequency and tie-line power interchange also vary. The objective of Load Frequency Control (LFC) is to minimize the transi...

To the Editor: In interesting paper, Fehr et al [1] showed relative erythropoietin deficiency in patients with GFR <40 mL/min, and concluded that it was the sequence of either altered set point for hormone production or due to renal tissue damage. On the other hand, Machiguchi et al’s paper [2] and our preliminary study led to extend Fehr’s explanation. Machiguchi et al [2] have shown that in p...
