This paper proposes an efficient mechanism of node membership verification within the groups of sensors in a wireless sensor network (WSN). We utilize one-way accumulator to check the memberships of the legitimate nodes in a secure way. Our scheme also supports the addition and deletion of nodes in the groups in the network. Our analysis shows that

• Abstract: Medieval philosophers were confident that they must and could interpret and assimilate philosophy i.e. Greek philosophy into the religious ethos. The medieval philosophers' reasoning on why it was necessary to incorporate philosophy into the religious ethos is because philosophy provided the proofs for theoretical opinions in reli

A fully integrated two-port surface acoustic wave (SAW) resonator, fabricated using a standard 0.6- m complementary metal–oxide semiconductor (CMOS) process is described in this paper. Only three micromachining processes, namely, reactive ion etching, zinc–oxide deposition, and wet etching, implemented subsequent to the standard process, are re

A Meta Analysis is a statistical technique for integrating quantitative results of the same research question from several sources. It is being applied in various disciplines including the medical and social sciences research,. One of the common problems with meta analysis data is when the variability measures, specifically, the standard deviations

The sensor reports from a wireless sensor network are often used extensively in the decision making process in many systems and applications. Hence, classifying real and false sensor reports is necessary to avoid unwanted results. In this paper, we propose a scheme for securing the sensor reports in a wireless sensor network. We use one-way hash ch

This paper highlights our work in developing an enhanced security framework for Bluetooth-based wireless personal area networks (WPANs). The basic security architecture of Bluetooth, operating at the link layer, is augmented with a higher application layer security mechanism for authentication and message integrity. This is necessary since the pres

This work is a contribution on the problem of the existence of Berge equilibrium. Abalo and Kostreva give an existence theorem for this equilibrium that appears in the papers [K.Y. Abalo, M.M. Kostreva, Berge equilibrium: Some recent results from fixed-point theorems, Appl. Math. Comput. 169 (2005) 624–638; K.Y. Abalo, M.M. Kostreva, Some existen

We investigated the common carotid artery (CCA) blood flow velocity in 5 healthy sedentary subjects using continuous wave (CW) Doppler ultrasound velocimeter which developed in our laboratory. The present study aimed to investigate non-invasively the effects of a short-term 4 week aerobic training program on the resting CCA blood velocity waveforms

This study aimed at evaluating the effectiveness of a Basic Islamic Parenting (BIP) course in providing information, awareness, and skills on various aspects of parenting. It also attempted to list major concerns and issues in parenting that can help improve future related courses. Data were obtained through a survey and an open standardized interv

Objectives: The aim of this study was to determine the prevalence and the types of menstrual irregularities among patients with SLE, and to identify factors that influence their development. Methodology: Sixty-one patients with SLE were enrolled into a cross-sectional, observational study. at medical clinics, University Science Malaysia Hospital (H
