The introduction of absorption refrigeration technology addressed several significant con-cerns in the domain energy crisis, rising cost fossil fuel, and ecological challenges aris-ing due to excess use traditional compression systems. ARS (absorption system) is gaining popularity as a result benefits such low-grade heat sources environmentally acceptable low-cost working fluid pairs. However, ...

In cognitive radio networks, the users are supposed to perform spectrum sensing with mush more accuracy to detect the more and more users. But in practice due to fading, shadowing etc., a long observation period of time is needed to make decisions based on detection which results in degradation of sensing performance. In this paper, we presented a new approach called Cuckoo Search for asynchron...
