the engineers can frequently encounter with the situation to select the optimum option among the alternatives related with tunneling operations. the optimum choice can be selected by the experienced engineers taking into consideration their judgment and intuition. however, decision-making methods can offer to the engineers to support their optimum selection for a particular application in a sci...

Bacteria encounter fluctuations in both their external and internal environments, and to manage these conditions, they employ various control mechanisms. In this issue of Molecular Cell, Hart et al. (2011) investigate how E. coli robustly controls nitrogen assimilation.

1.0 INTRODUCTION Advancement in technologies such as sensing, electronics and computing have attracted tremendous research interest in the field of wireless sensors network (WSNs). Apart from their enormous potential for both the commercial and military applications wireless sensors network is generally consist of large number of low cost, low power multifunctional energy constrained sensors no...
