The stock exchange and its performance are important indicators of the economic health of an economy. Electricity generation capacity supports industrialisation. National electricity distribution on the other hand, however, even when mediated with electricity imports to augment a low generation capacity, can complicate both manufacturing and non-manufacturing companies’ desire to operate in an economy which is attempting to industrialise. This is compounded if generation is not matched to consum...

This paper introduces a novel approach to drive system design for compact autonomous electric vehicles (AEVs) by utilizing topology optimization and simulation techniques. The primary goal is to develop an efficient and lightweight drive system that improves vehicle performance, taking into account the specific requirements of autonomy and electric propulsion. The design process incorporates topology optimization to systematically explore different configurations and material distributions, with...

It is no longer news that the Nigerian Power sector is inundated with myriads of challenges to satisfy the energy needs of consumers. In this paper, an energy audit assessment of standalone PV system “a case study of heartland radio broadcasting station” is conducted which offered the most accurate estimate of energy savings, cost and provided uninterrupted power to the Broadcasting Station. The results obtained showed that the annual electricity bill of the broadcasting house dropped reasonably...

The architectural heritage is a unique, material expression of history and culture. Bearing in mind, that the future of the historical buildings mostly depends on their integration into the economic life of the country and the sustainable development requires an adequate approach, the European Union’s experience in capitalizing architectural heritage is highly valuable. Real European examples proved that historical buildings preservation and their development and contribution to the economy are ...

In recent years, the scale of China’s construction industry has been expanding, and construction companies have gradually revealed some problems. Among them, cost management issues are more prominent, especially the management of hidden costs. Because of its strong concealment, the structure is more complicated and difficult to quantify. As a result, a complete research system has not yet been formed. This paper analyzes the influ ...

Engineering quality evaluation is an important part of engineering quality management. However, China has not yet formed a systematic engineering quality evaluation system. Aiming at such problems, a comprehensive evalua-tion method based on artificial neural network for residential project construc-tion quality is proposed. Based on the analysis of the quality influencing factors in the construction process of ...

Since the hidden costs of construction projects are subtle and strong, difficult to quantify, it has not yet resulted in completing research system. This paper analyzes the literature to identify the concepts and forms of hidden costs, then summarizes the factors affecting the construction of 20 projects in hidden costs. Factor analysis extracted six comprehensive factor variables to represent ...

Solar power has gained great usage in electricity generation world-wide, and stand-alone is common in Rwanda. Site visits and energy audit estimates for a typical residential house in Rwamagana district, were used to cost effectively compare stand-alone and grid-tied PV systems able to supply 7.2 kWh/day, load. Algorithms design of lifetime costs and benefits were developed, to analyse total daily energy requirements using Frequen ...

The creation of a
matrix of minimum mandatory requirements for building a reliable system to
counter potential terrorist threats is essential to increase the security and
protection of critical infrastructure. In order to obtain an objective
assessment of the success achieved in terms of necessary level of security and
the extent to which is reached the reliability of critical infrastructure we
should use a standardized approach and criteria. This is the purpose of this
article, namely, to prese...
