A new economical mixed nite element is formulated for the Stokes equations, in which the two components of the velocity and the pressure are deened on diierent meshes. First order error estimates are obtained for both the velocity and the pressure. Furthermore, the well known MAC method is derived from the resulting nite element method and the optimal error estimates for the MAC method are also...

Wireless networks are the widely used networks for communication now days. Hence it is very necessary to improve the performance of the Medium Access Control (MAC) layer by preventing the communication from collisions. In this work a new scheme is explained, for efficient channel access, which is based on the sequencing. The proposed method minimizes the number of collisions as well as the dela...

OBJECTIVES In order to select new drugs and to predict their in vitro activity against Mycobacterium avium complex (MAC), new quantitative structure-activity relationship (QSAR) models were developed. METHODS The activities against MAC of 29 structurally heterogeneous drugs were examined by means of linear discriminant analysis (LDA) and multilinear regression analysis (MLRA) by using topolog...

Emanuel Fuchs 11 Furthermore a new method for the automated evaluation of earth faults is introduced. The new method determines the detuning and the damping, based on the decay process, in the frequency domain. For the automated evaluation of earth faults the accurate registration of the distinguishing moment of an earth fault is necessary. For the accurate registration a new method is introduc...

Applications of wearable and implanted wireless sensor devices are hot research area. A specialized field called the body area networks (BAN) has emerged to support this area. Managing and controlling such a network is a challenging task. An efficient media access control (MAC) protocol to handle proper management of media access can considerably improve the performance of such a network. Power...
