INTRODUCTION Ethiopia achieved a rapid expansion of TB microscopic centers for acid fast bacilli (AFB). However, external quality assurance (EQA) services were, until recently, limited to few regional and sub-regional laboratories. In this paper, we describe the decentralization experience and the result of EQA using random blinded rechecking. MATERIALS AND METHODS The routine EQA quarterly r...

In this paper a relationship between two approaches towards construction of genuinely two-dimensional upwind advection schemes is established. One of these approaches is of tile control volume type applicable on structured cartesian meshes. It resulted (see [14], [15]) in the compact high resolution schemes capable of maintaining second order accuracy in both homogeneous and inhomogeneous cases...

This paper presents a novel countermeasure against Distributed Denial-of-Service (DDoS) attacks that we call the rouTer poRt mArking and paCKet filtering (TRACK), which includes the functions of both IP traceback and packet filtering. TRACK is a comprehensive solution that is composed of two components: a router port marking module and a packet filtering module. The former is a novel packet mar...

there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
