Remote Monitor and Controller System for Power Generators

Stand-alone power generating sets have become a source of alternative power supply in Nigeria for decades now, especially for business owners, corporate bodies, industries, as well as individuals, due to the epileptic condition of the electric power utility. The proper management, as embodied in the control and maintenance of such systems, has remained a source of concern as power failures are critical to the productivity of such users, especially industries and businesses. In this paper, a Remote Monitor and Controller System (RMCS) for power generators is designed to improve the operation and maintenance of power generators. The RMCS, which includes both a hardware module and software, provides a functionality that allows a power generator to be controlled and monitored from a remote location

Auxiliary Winding Switching Circuit for Single-Phase Induction Motors

The most common practice for starting a single-phase induction motor is to connect a starting capacitor, in series, with the auxiliary winding. Here, the possibility of using an electronic switch in parallel with the starting capacitor, is discussed. This work relates particularly to a switching device for electrically connecting and removing the auxiliary winding and starting capacitor from the single-phase induction motor's circuitry. The starting capacitor with the auxiliary winding are disconnected by electronic means as the motor gains speed hence leaving only the main winding in the motor circuit for normal operation

Automatic Transfer and Controller System for Standby Power Generator

An automatic transfer system (ATS) was developed to monitor the a.c. voltage coming from Power Holding Company of Nigeria (PHCN) line for power failure conditions. Upon detection of an outage for a predetermined period of time, the standby generator is started, once is up to speed, the load is transferred from the PHCN line to the local Generator. This ATS is capable of electrically monitoring fuel level, oil level, Battery strength, next maintenance schedule and then start or stop the unmanned Generator from the computer system located in the comfort of homes or offices outside the Generator site. In this paper therefore, an Automatic Transfer System (ATS) for Power Generator is designed to improve the operation and maintenance of power generators. The ATS which includes both hardware and software module, provides a functionality that allows a power generator to be controlled and monitored from a remote locatio

Trend analysis of the Nigerian budgetary allocation to the education sector from 2009 – 2018 with Reference to UNESCO’S 26% Benchmark

The importance of education in boosting the manpower of an economy cannot be overemphasized. This critical sector has been bastardized, relegated and put in a dust bin position through paltry figures usually allocated to it by the Federal Government of Nigeria. This paper presents a holistic trend of budgetary activities in Nigeria with a particular focus on the allocation to the Education sector using times series approach from 2009-2018. Two research questions were answered using secondary data gathered from the Central Bank of Nigeria's Statistical Bulletin, 2018. Collected data were analyzed using descriptive statistics, while the results of the analysis showed that, the total allocation to the education sector from 2009 – 2018 is N4,038,115,000,000. The results further revealed a difference of N 10,311,805,000,000 between UNESCO benchmark of 26% and the actual allocation to the education sector for the same time period. It was concluded that the total allocation made to the education sector within the time period of 2009-2018 is generally low, and below the UNESCO benchmark. Based on the findings, it was recommended amongst others that the Federal Government of Nigeria should adequately fund the educational sector by allocating at least 26% of her budget to the education sector as prescribed by UNESCO

INTERCÂMBIO SOBRE ÁGUAS TURBULENTAS: OS ANIOMA E O COMÉRCIO EM TEMPOS DE GUERRA COM BIAFRA, 1967-1970

A lot has been written on the Nigeria-Biafra war which lasted from 1967 to 1970. However, little attention has been given to a very important but almost forgotten part of that war. This is the trade that took place between the Anioma people on the Nigeria side and Biafrans across the River Niger. It has been called ‘ashiaattack’. The trade played a very important role in prolonging the survival of Biafra as essential commodities were ferried across the Niger in a trade that proved very lucrative for traders on both sides. The trade was labelled clandestine because it was forbidden by federal authorities while it was encouraged by Biafran authorities hemmed in and challenged by the economic blockade ringed around her by the former. The neglect of this important phenomenon in the Nigeria-Biafra war, particularly from an Anioma perspective, represents a void that needs to be filled if some finer details of the war are to be understood. It is important in helping glue some facts together to make for a deeper explanation of aspects of the war. In undertaking this task and employing mostly oral sources, this paper highlights and discusses the dynamics of the trade; its larger significance in the Nigeria-Biafra war that pitched the Igbo population of Nigeria against the other Nigerian ethnic groups as well as the consequences of the trade for the Anioma. Muito foi escrito sobre a guerra Nigéria-Biafra que durou de 1967 a 1970. No entanto, pouca atenção foi dada a uma parte muito importante, mas quase esquecida dessa guerra. Isto é, o comércio que ocorreu entre o povo Anioma do lado da Nigéria e Biafra através do rio Níger. Foi chamado de "ashia attack" ou “comércio de ataque”. O comércio desempenhou um papel muito importante no prolongamento da sobrevivência de Biafra, uma vez que as mercadorias essenciais foram transportadas através do Níger em um comércio que se mostrou muito lucrativo para os comerciantes de ambos os lados. O comércio foi rotulado de clandestino porque foi proibido pelas autoridades federais enquanto era incentivado pelas autoridades de Biafra e desafiado pelo bloqueio econômico tocado ao seu redor pelo primeiro. A negligência deste importante fenômeno na guerra Nigéria-Biafra, particularmente de uma perspectiva de Anioma, representa um vazio que precisa ser preenchido para que alguns detalhes mais finos da guerra sejam compreendidos. É importante para ajudar a unir alguns fatos para fazer uma explicação mais profunda dos aspectos da guerra. Ao realizar essa tarefa e empregando fontes principalmente orais, este artigo destaca e discute a dinâmica do comércio; sua grande importância na guerra Nigéria-Biafra que lançou a população Igbo da Nigéria contra os outros grupos étnicos nigerianos, bem como as consequências do comércio para os Anioma

Fiscal Federalism and Development In Nigeria

It is a known fact that the nature of fiscal federalism the military government imposed on the nation has no regards for the source of production and revenue generation. This was as the result of constitutional empowerment that put the federal government in charge of payment and tax collection.This has gone a long way to hamper revenue generation effort and subject states as agents of federal government. Despite various committees and commissions’ recommended principles and formula, conflict are still brewing. Though previous scholarly works have been geared towards the adoption of an acceptable revenue sharing formula for equity and fairness to take its root, but what is obtainable generates internal ramblings in the polity, cold war amongst the various ethnic groups and a yardstick in understanding lack of sustainable development in the country. In the course of finding solution to this problems, this paper focuses on the following issues: Nigerian fiscal federalism, effect on development, its importance to national development, summary of the existing various principles and sharing formula, the contending issues, objective of fiscal relations and theory of fiscal federalism. The system approach was used in analysing the various component in its theoretical framework. Historical method was used in gathering data and documentary analysis was used to analyse secondary data to arrive at conclusion which recommendations were made for an enhanced fiscal federalism for a sustainable development
