Technological advancement in this contemporary age has, obviously, turned the world into a global village. The art of news gathering and dissemination has become phenomenal. All one needs do is punch the right buttons on the computer or mobile phone and the world is, as it were, at your feet! This has brought to fore an endless stream of disturbing news of chaos, violence, brutality and absurdity across the nations of the world – all of which are, surreptitiously, pushing the human soc...
Transmission of high data rate over multipath environment is associated with many wireless applications. However, this transmission results in high delay which leads to inter-symbol interference (ISI) distortion and causes high error. The existing linear equalizer (LE) in multiple-input multiple-output (MIMO) systems such as zero forcing (ZF) equalizer used in addressing this problem reduces the ISI distortion completely but results in noise amplification. Likewise, minimum mean square error ...
Our work involves the development of a quadcopter Unmanned Aerial Vehicle (UAV) system with remote sensors onboard for monitoring oil and gas pipelines. Two Liquefied Petroleum Gas (LPG) sensors were used for LPG gas leakage detection. The Multiwii software is used to control, track and simulate the 3D motion of the UAV in flight. Using this device, experimental data from field tests were analyzed with MATLAB. Results reveal that the developed system has performed as expected. Thus, our devic...
Erratic power supply from the utility grid has grave effect of the development of several countries. In a bid to overcome this challenge, many residential buildings have become electrically self-sustaining by the integration of various backup power supply source. Yet the act of transition from one source to another has remained a manual task that tends to discourage users from going through the rigour. Internal combustion engine AC generators and batteries have been found to be the most c...
Integrating renewable energy hybrid distributed generation (REHDG) into distribution network systems (DNSs) has become increasingly important because of various technical, economic, and environmental advantages accruing from it. However, the output power of REHDGs from photovoltaic (PV) and wind is highly variable because of its dependency on intermittent parameters such as solar irradiance, temperature, and wind speed. Such variability of generated power from large-scale REHDGs or load...
