Energy consumption has emerged as a first class computing resource for both server systems and personal devices. The growing importance of energy led to rethink in hardware design, hypervisors, operating compilers. Algorithm design is still relatively untouched by the algorithmic complexity models do not capture consumed an algorithm. In this paper, we propose new model account used Based on abstract memory (which was inspired popular DDR3 similar parallel disk I/O Vitter Shriver), present...

Precision agriculture is the collection of hardware and software technologies that allow a farmer to make informed, differentiated decisions regarding agricultural operations such as planting, fertilizing, pest control, harvesting. In recent years, advances in machinery emergence robots continuously increased resolution at which treatment possible. This creates corresponding need for information fine spatial temporal resolution. Autonomous multi-robot systems (e.g., unmanned ground aerial...

Some enzymes can catalyze more than one chemical conversion for which they are physiologically specialized.

Hash-based message authentication code (HMAC) involves a secret cryptographic key and an underlying crypto-graphic hash function. HMAC is used to simultaneously verify both integrity authenticity of messages and, in turn, plays significant role secure communication protocols e.g., Transport Layer Security (TLS).
