Electricity is vital for modern society, powering homes, industries, hospitals, and transportation systems. It is the backbone of our daily lives, enabling convenience, fulfilling human basic needs, and crucial for the development and improvement of socioeconomic conditions. However, the Democratic Republic of the Congo faces a significant challenge with low electrification rates, where less than 10% of the population has access to electricity. Even the capital city, Kinshasa, with 17 million in...

The main determinant of the cost price of a solar panel in the market is the rated peak power as measured under standard laboratory conditions (cell temperature of 25?C, solar irradiance of 1000 W/m2 and an air mass of 1.5). An indirect method (considered indirect since the measurement is done under nonstandard laboratory conditions) is adopted here in order to approximate with some degree of certainty the rated peak power of a solar panel. It involves the use of a characterized solar module of ...

In modern life and production, there exists a global energy crisis, an increasing demand for advanced medical services, and a need to integrate and miniaturize industrial products. The applications based on conventional actuators struggle to cope with crises and growing demands due to their low resolution. To address the above issues, researchers have been working on and developing the excellent properties of piezoelectric materials since the discovery of the piezoelectric effect. Nowadays, piez...

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...

The investments of power transmission projects are steadily increasing in recent 20 years. However, it is rare to investigate the suitability of the project delivery methods for power transmission projects. In fact, it is not an easy task to select an appropriate project delivery method as a large amount of ambiguous and uncertain information exists. This paper thus aims to develop an uncertain multiple attribute decision making (MCDM) model to help owners of power transmission projects to choos...

This paper presents a detailed simulation model designed for autonomous electric vehicles (AEVs) powered by lithium-ion batteries. It provides insights into the input parameters used in the model and the recuperation of braking energy in AEVs. In addition, the paper offers a thorough analysis of the dynamic characteristics of lithium-ion batteries through simulations of standardized driving cycles, including urban and highway drive cycles. These results are expected to facilitate the progress of...

Since the 1980s, the city of Dakar has been facing a significant water supply deficit due to rapid population growth. To address this issue, certain communities have implemented autonomous water supply systems utilizing submerged pumps. However, these systems are plagued by a major drawback: frequent pump breakdowns. The objective of this study is to identify the causes behind these breakdowns and propose technical solutions to enhance the reliability of these systems. To achieve this goal, an a...

The rising popularity of mobile payments can be attributed to the widespread use of smartphones and their applications. Despite its potential to simplify our lives, its adoption in African countries has been limited. This paper aims to enhance our understanding of the critical factors that influence the acceptance of mobile payments in Nigeria by exploring the impact of “network externalities” in addition to conventional technology acceptance factors. It posits that performance expectancy, effor...

Real-time monitoring of temperature is required during the calcination process of Nixing pottery. In order to solve the problem of unattended temperature checking, this thesis focuses on the use of the STC89C52 microcontroller as the core of the hardware, with the DS18B20 temperature sensor for real-time temperature collection, through the mobile phone APP to simulate the real-time monitoring of the pottery kiln temperature, and to make the corresponding historical data line graph. When the coll...
