Paper ID: ATE-70405020
Pages: 1 - 5
Abstract: In this work, a microcontroller based football stadium population counter was designed and implemented hands on using two active infrared sensor systems and the microcontroller system. The active infrared sensor systems consisted of an active sensing section whose task was to detect persons separately one after another using different entrance and exit points of the football stadium but also in robotics applications. From the sensing system a signal conditioning circuit was used in order to get a suitable and desirable output signal that the microcontroller could recognize and process. The microcontroller system, whose task was to determine the number of persons inside the stadium, consisted of one AT89C51 microcontroller outputting to the seven segment displays. By recognizing both the number of entering and leaving persons, the microcontroller executed a simple high level language program to determine the real number of spectators inside the stadium, and then displayed the obtained result on the seven segment displays. The counter system was designed with a capacity of 9999, although this could be improved through cascaded systems or by using more advanced embedded systems or robotics techniques.

Title: An Overview Of Power Sector Laws, Policies And Reforms In Nigeria
Author(s): Zubairu Gatugel USMAN and Serkan ABBASOGLU
Paper ID: ATE-80414027
Pages: 6 - 12
Abstract: This paper is concerned with Nigeria's energy sector challenges and reforms put forward by the Government to tackle the challenges. Laws and policies aimed at addressing the various energy generation, transmission and distribution challenges bedevilling the energy sector are stated and explained. Various strategies were employed by the Government which include encouraging private sector participation, diversification of the energy generation sources and promoting energy efficiency for sustainable development. The Government has spent billions of dollars since 2003 in the construction of new power generation facilities, transmission lines and distribution centres to boost the power supply and at the same time initiated the process of selling off the existing facilities to private investors. Also, the Energy Commission of Nigeria embarked on programs and strategies aimed at boosting energy generation from renewable sources. On the other hand, the commission focus on the need for energy efficiency on both demand and supply side to reduce greenhouse gas emissions and viability of energy systems. The renewable energy sector was boosted by the implementation of various renewable energy generation projects such as the Lekki biogas plant, the Katsina wind farm and the establishment of renewable energy research and development centres across the country.
