The geostrategic location of North Africa as a crossroad between three continents and as a stepping-stone outside Africa has evoked anthropological and genetic interest in this region. Numerous studies have described the genetic landscape of the human population in North Africa employing paternal, maternal, and biparental molecular markers. However, information from these markers which have dif...

extended abstract abstract pressure management is an effective method for water demand management. for evaluation of the effects of pressure changes on leakage level of water networks, the favad equation is usually used. however, in this equation, exponent of pressure parameter (n) needs to be determined. for estimation of n, either some information about the leak opening is necessary or networ...

This paper presents a new approach to Dynamic Texture (DT) classification based on the spatiotemporal analysis of the motion. The Grey Level Co-occurrence Matrix (GLCM) is modified to analyse the distribution of the magnitude and the orientation of the Optical Flow which describes the motion. Our method is therefore called Combined Co-occurrence Matrix of Optical Flow (CCMOF). The potential of ...

Most memory corruption attacks and Internet worms follow a familiar pattern known as the control-data attack. Hence, many defensive techniques are designed to protect program control flow integrity. Although earlier work did suggest the existence of attacks that do not alter control flow, such attacks are generally believed to be rare against real-world software. The key contribution of this pa...

Traditional attack detection schemes based on packets or flows have very high computational complexity. And, network based anomaly detection schemes can reduce the complexity, but they have a limitation to figure out the pattern of the distributed global scale network attack. In this paper, we propose an efficient and fast method for detecting distributed global-scale network attack symptoms in...

In this paper, numerical investigation of upward two phase flow of air-water has been studied. Different conditions of flow regimes including annular, wispy annular, slug, churn and bubbly are simulated based on Hewitt and Roberts map, and a good agreement between the experimental data of the map and the numerical simulation has been observed. Accordingly, a proper CFD model in CFD software of ...

Flow experience is a state of mind in which one is totally absorbed in a task. This study explored the daily flow patterns related to working and non-working tasks among healthy and non-healthy (burned-out) individuals using the Experience Sampling Method. The main aim of this study was to explore flow throughout the day using an operationalization that focused on the flow experience itself, as...
