Microcontroller Driven GPS Clock
Abstract: ABSTRACTGPS satellites (and now GNSS also) generally include more than three (or four) atomic clocks which are monitored and controlled for being highly synchronized and traceable to coordinated universal time as national and international standards. Thus for synchronization of time, the GPS signal is first received, then processedwith help of a“local master clock”, time server, or primary reference, and passed on to "slaves" or other devices such that their "local …

Design and Fabrication of Pedal Operated Air Compressor
Abstract: The first idea for powering the pump would be a stationary bicycle. Pedal power is simple, efficient, and practical. Its most familiar use is the bicycle for personal or cargo transportation. But pedals can also power small stationary machines. Since the system is to remain human powered and large amounts of power are required, having the operator use their stronger leg muscles was intuitive. A stationary pedal driven device seemed …

Valorization of agro-industrial waste into bioethanol: a case of brewers spent grain
Abstract: AbstractThe global impetus to produce alternatives to petroleum-based fuels and value-added chemicals to reduce greenhouse gases are putting pressure on the industries to diversify and valorize byproducts. By-products valorization of the brewery industry such as spent grain has given critical attention for long-term socio-economic and environmental benefits. Brewer`s spent grain is the major by-product of the brewing industry, represses around 85% of the total by-product generated. In the current work, …
