Three Phase Coil based Optimized Wireless Charging System for Electric Vehicles

With modernization and technology enhancements on a global scale, environmental consciousness has also been increasing in recent days. Various technologies and automobile industries are vandalized with sustainable solutions and green technologies. Transportation via roadways is mostly preferred for distant travel as well, despite the advancements in airways and railways, due to less capital outlay, door to door service possibility in rural areas etc. The conventional fuel vehicles are a huge contributor to environmental pollution. Electric vehicles are an optimal solution to this issue. The lives of the common masses are not impacted largely by the electric vehicles despite their market commercialization since a few decades. It is due to certain challenges associated with the electrical vehicles. A 100% efficient perpetual machine does not exist yet. Predominantly, challenges related to charging, hinders the success of e-vehicles. Frequent charging is required in case of long-distance travel and other scenarios in the existing vehicles. Based on the respective governments, extensive changes are made in the infrastructure to overcome the issues at the charging stations. In this paper, an enhanced wireless charging module for electric vehicles is presented. The use of multiple coils is emphasized for building up energy and transmitting it. The inductive power transfer mechanism and efficiency of the system are improved with the design of a three-phase coil. The mechanism for assessment of the energy consumed in e-vehicles is also discussed.

Success criteria-based impacts of risk factors on education building projects in southwestern Nigeria

Purpose Despite the huge capital outlay in tertiary education building projects (TEBP), these projects undoubtedly failed in meeting the set objectives of cost, time and quality, among others. Therefore, rather than the impacts of risks on the overall project performance, which is common in the construction management literature, the purpose of this study is to assess the impacts of risk factors on the criteria for measuring the success of public TEBP. Design/methodology/approach The paper adopted a quantitative research method where the data collection was via a questionnaire survey. The researcher administered 452 questionnaires to the client representatives, consultants and contractors involved in building projects across five public tertiary education institutions in Ondo State, Nigeria. Of 452 questionnaires, 279 were retrieved and suitable for the analysis, translating to a 61.73% response rate. The reliability analysis of the research instrument showed 0.965 and 0.807, via Cronbach’s alpha test, indicating high reliability of the instrument used for data collection. Findings The study found different risk factors affecting the criteria for measuring the success of TEBP. For instance, the environmental risk factor significantly impacted completion to cost, while financial and political risk factors significantly impacted completion to time. In addition, while environmental, legal and management risks significantly impacted end-user satisfaction, safety performance was significantly impacted by logistic, legal, design, construction, political and management risks. Besides, the logistic, legal, design, construction, financial, political and management risk factors impacted profit. However, despite profit being one of the criteria for measuring the success of building projects, it recorded the highest risk impacts amounting to 41% variance. Research limitations/implications The findings are limited to the public tertiary education building projects procured via competitive tendering; therefore, the results might differ when considering other procurement methods. Practical implications The practical implication is that rather than focusing on all risk factors, the project stakeholders could give adequate attention to the significant risk factors impacting each of the parameters for measuring the success of education building projects. Originality/value The study revealed specific risk factors impacting the criteria for measuring the success of TEBP, which extend beyond the use of the overall project performance approach.

Development of low-cost reflective plate thermal energy absorber systems for application in South Africa

An innovative solar heat collector system was developed from low-cost materials by applying innovative design technology and using adaptive technologies. The system design entails placing long black polymer pipes connected in series circulation, mounted and positioned in grooves of inverted box rib galvanised steel plating. The grooves reflect and focus the incident rays on the centre piping, concentrating incident sun rays on the black piping and increasing the absorption of thermal energy in the piping filled with circulating water. The circulation of the water is facilitated by a direct-current solar-driven pump powered by a small photovoltaic panel. The thermal energy as collected is stored in a standard household geyser tank. A 3 × 4 m heat absorber of this type collects approximately 10 kWh of energy per day. The estimated cost of the system, considering the capital outlay over an expected ten-year life cycle for the product was estimated at R0.25 per kWh. This pricing competes extremely favourably with the general cost of grid electricity in South Africa for medium-sized households, which is of the order of R2 per kWh up to 1000 kWh per month, including taxes. With an estimated electricity cost escalation of above 5% every year, the ten-year saving for a household using this prototype can be approximately R200 000. The technology and designs developed through the study can create many new business opportunities in South Africa in both urban and rural environments, through manufacturing, installing, repairing, and maintaining the systems.

Relationship between Commercial Banks Credit and Per capita net state domestic product of India: A Regional Panel data analysis

In general, bank credit plays a pivotal role in economic growth. Because bank credit may stimulate the capital accumulation and rate of saving that further induce the economic growth. However there are no unanimous opinion on the relationship between bank credit and economic growth. Under these circumstances, an attempt has been taken in this paper to investigate the role of bank credit, capital outlay and government’s social sector spending on per capita net state domestic product of India . this study finds that random effect model is better than fixed effect model and expansion of bank credit significantly affecting the per capita net state domestic product, capital outlay also positively and significantly affecting the per capita net state domestic product

SPATIAL ANALYSIS OF PADDY RICE PRICE VARIABILITY IN DASS AND TAFAWA BALEWA LGAS OF BAUCHI STATE, NIGERIA

The study was conducted on the spatial analysis of paddy rice (Oryza sativa) price variability in Dass and Tafawa Balewa LGAs of Bauchi State, Nigeria. Data were collected using questionnaires administered to 120 respondents sampled through random sampling technique. Secondary data were also collected from BSADP Bauchi on monthly prices of paddy rice. Data were analyzed using descriptive statistics (mean, frequency, ranking and likert scale), pearson product correlation, T-test and ratio to moving average model. It was revealed that the leading causes of spatial rice price variability were spatial variation in supply, high cost of transportation and inadequate market information. There was existence of price integration or perfect price transmission between and among the urban and rural markets during the period of study. The magnitude of paddy rice price variability in the rural markets were higher, and the t-test shows that there was a significant (P < 0.05) difference in price of paddy rice between rural and urban markets. Spatial variation in supply, bad road condition, seasonal variation in supply, inadequate contact with extension agents and low capital outlay were the major constraints militating against paddy rice marketing in the study area. Therefore, it is recommended that Rural feeder roads should be constructed by government, NGOs or individuals to enable easy movement of produce as well as all year round production/supply of rice should be encouraged through provision of fund and inputs by relevant stakeholders to farmers for dry season farming in order to curtail the problem of price variation due to seasonality in production.

Optimized Technical and Commercial Strategy for Marginal Field Re-Entry – A Case Study

This paper examines an optimized strategy and approach for executing a marginal field re-entry in the face of harsh global economic realities in the oil and gas sector. With dwindling and depressing oil prices driven by demand & supply volatility with root causes traceable to some factors such as the prevalent health pandemic, clamor for green energy, climate change discussions, geopolitics etc, the operating model for oil companies will need to drastically change to reflect current realities. Due to rapid global urbanization and increasing population amongst other factors, there is a corresponding huge appetite for oil to meet energy demands. This has led to exploration in unconventional terrains, utilization of the full extent of primary and secondary recovery mechanisms to attain high RFs in already producing fields and in some extreme cases, the development of marginal fields. In the Niger Delta area of Nigeria, marginal fields usually given up by Oil majors or abandoned following production exigencies and government laws are acquired and operated by indeginous companies. These indigenous players look for the most cost-effective means to produce these assets as it becomes the only way to make profit. A case study for field re-entry in the Niger Delta, which emphasized relatively/comparatively reduced capital outlay dependent on the technical approach is examined. Lessons learnt are drawn to aid enlightened go-forward actions and that will ensure a go-to template for similar future marginal field re-entry projects.

Organizational strategic marketing management: Critical analysis of the marketing strategies / practices currently employed by the Water Resources Commission, Ghana, indicating challenges and opportunities.

Strategic marketing management is the implementation of an organization’s marketing mission through focused processes to get the most out of existing marketing plan and to identify target customers. Again, it is to help the discovery of other marketing opportunities for the organization to transform plans into reality. The marketing plan should outline the marketing strategy of the organization for the coming year, quarter or month. A typical business marketing plan should include: overview of the marketing and advertising goals, description of the current marketing position, timeline of when tasks within the strategy will be completed, key performance indicators to be tracked, and description of the target market and customer needs. When an organization adopts this approach to market its products / services to customers / consumers, there is a strong expectation of success for the organization. The initial capital outlay pumped into businesses is normally huge, and this should not be made to go waste. However, most organizations gloss over this important point and put out mediocre plans and strategies to managing their businesses. Business wo/men should project their businesses from a better marketing angle with good competitive strategy to enable them achieve competitive advantage.

Sustainable transport: From high carbon to carbon neutral

Purpose – This paper seeks to explore the transition and process of migrating from high dependence on internal combustion engine (ICE), to one that is a sustainable carbon neutral fleet. Design/Methodology/Approach – Comparative studies will be completed for commercial vehicles with combustion engines and carbon-neutral alternative vehicles. Findings – This paper provides informed decision for people who may wish to consider alternative sustainable carbon neutral propulsion systems. Practical implications – Historically, modes of transportation rely on the conversion of chemical (stored) energy to motion via the use of internal combustion engine (ICE). However, with more awareness, rise in “Green” consumers, and government policies, businesses are open to exploring sustainability and reducing their carbon footprint contribution to the environment. This study suggests that there will be some level of trade-off discussions needed to make such decisions based on the different requirements, industries, geographical locations, and the environment in which such businesses operate. Some companies will be able to justify the need to be more carbon neutral, though some may not, or off-set the capital outlay required to transition and remain carbon neutral, without some form of external help.

Przedsiębiorczość społeczna w tworzeniu podstaw bezpieczeństwa społecznego wspólnot lokalnych

Contemporary processes of administration are of a complex character. It requires from policymakers who form the economic policy the choice of adequate and diverse methods and interaction techniques. One needs to be aware of the fact that creating suitable conditions for socio-economic development should take place on different levels of a country’s organisation. Stimulation of development is inscribed into the core and nature of local government actions and supporting social entrepreneurship constitutes one of the biggest challenges on the level of municipalities and counties. The aim of the study is to point to the meaning of social entrepreneurship in creating the foundations of social security. Social entrepreneurship is inseparably connected to one of the contemporary trends in the economy, namely the social economy. In Poland, the social economy has been gaining in popularity in recent years, following a number of negative social effects observed after the rough period of economic transformation and its ownership and structural transitions. In the study, the essence of social entrepreneurship has been characterised as an important action aimed at improving the feeling of social security. The reference has been made to Świętokrzyskie voivodeship, in which the meaning of social entrepreneurship has been pointed and attributed by policymakers responsible for the development policy. The stimulation of social economy subjects may be an important supplement of regional policy aimed at attracting external investments (with shortages of capital connected to the regional policy). This results from the fact that launching business in the social economy sector does not require significant capital outlay, and may constitute a chance for involving young people who want to test themselves in a role of budding entrepreneurs. Promotion of social entrepreneurship might as well contribute to the reinforcement of social cohesion as well as building regional social capital by including into the labour market some groups that are “forgotten” and feel it difficult to find themselves on the open labour market. The article is of an overview character.

Solid Financial Reforms are Needed to Uplift the Distressed Real Estate Sector

After the pandemic COVID-19 breakout, there has been a significant decline in the property listings. Though the Centre has focused on the affordable housing space for reforms, there has been no visible reforms in view of the realty developers. Due to the recent moratorium imposed on the term loans, credit sources have been tightened for the realty developers coupled with other aspects. Given the difficulty in credit availing conditions in the sector, the article discusses the distressed funds as alternatives to uplift the sector. However, there are certain hurdles for the distressed funds in the form of capital structures to act quickly and operate efficiently. The article in this regard discusses certain changes in the regulatory framework that allows flexibility in the capital outlay in the residential real estate projects.
