Recent Advancements In Stepped Solar Still & Its Performance Parameters

Recent Advancements in Speech Enhancement

Speech enhancement is a long standing problem with numerous applications ranging from hearing aids, to coding and automatic recognition of speech signals. In this survey paper we focus on enhancement from a single microphone, and assume that the noise is additive and statistically independent of the signal. We present the principles that guide researchers working in this area, and provide a det...

A comprehensive decade review and analysis on designs and performance parameters of passive solar still

The simplest and easily accessible type of solar distillation is passive solar still which utilizes freely and abundantly available sun energy for removal of salinity/impurity from saline/brackish water. The main drawback of passive solar still is its lower efficiency and distillation output. Different designs of passive solar stills are fabricated and tested by various researchers to meet wate...

Performance of Rotating Solar Still with Rotating External Reflectors (RESEARCH NOTE)

In this research, a rotating solar still that uses external bottom reflectors was experimentally investigated. The solar still and reflectors have the capability to shift their angle with respect to the south and the reflectors have the capability to shift their angle with respect to the horizon. The experiment has been performed in both fixed and rotating states. For the fixed state the solar ...

Recent Situtation and Future Advancements

50 years are an extended epoch to consider for developments in epileptology. Th erefore only a selection of important milestones can be covered with regard to available space. After looking back to the past current activities and important aspects for future research will be discussed. Concerning epidemiology one of the fi rst important studies investigated the role of precipitation of epilepti...
