Multi-Criteria Computer Aided System for Industrial Machines' Performance Assessment

Olasoji Rasak Olagunju, Basil Olufemi Akinnuli, Pius Bamidele Mogaji, Olayinka O. Awopetu
Efforts have been made by some researchers to determine machines' economic performance, some considered engineering features, some supply conditions while some look into the productivity as well as profitability of the machine separately. Recently, [1] saw the performance assessment of machine as surrogate problem and they deviate from single strategic decision common in past researches to multi-criteria approach in their research. Considerations were given to: annual operation cost, machine eff...

A Product Analysis and Evaluation Method Based on the “False-Green-Design”

Yujia Jia, Heliang Gao
With the impact of human socio-economic development on the environment at this stage, the society has gradually realized that the relationship between socio-economic development and environment needs to be further coordinated for the batter symbiotic relationship. Green design is related to the common interests of all human being, it, as a design concept, has already been agreed with different sectors. However, due to the profitability of companies operating, the products marked with “green desi...

Déja vu and Wind Turbines: A Review of Lived Experiences after Appeals of Ontario Industrial-Scale Wind Power Facilities

Jane Wilson, Carmen Krogh, Paula C. Peel
This paper is a review of reports of lived experiences of residents in rural/small-town Ontario, Canada and a comparison to the concerns raised during citizen-sponsored appeals of industrial-scale wind power project approvals. We found that the concerns leading to the decisions to appeal power projects have been borne out in real-life experience, as government documents record thousands of complaints about adverse effects on the environment and human health. These findings support the need for e...

Assessment of the Energy Potential of Municipal Solid Waste (MSW) in Freetown, Sierra Leone

Andy Otis Ngegba, Akopon J. Bertin
Electricity supply in Freetown has been unreliable partly due to lack of sus-tainable alternative generation sources, and the city is beset by poor waste management system, which has led to indiscriminate waste disposal since the end of the country’s civil war in 2002, contributing to air and water pollution. This necessitates the need for research and development on Waste-to-Energy (WtE) technologies. Waste generation was estimat

Determining the Radius of the Magnetic Vortex Core of YBCO123 and Bi2212

A. Mukubwa, Fred Masinde
A plasma has been defined as a quasi-neutral gas of charged particles showing collective behaviour. Plasmas can support waves depending on the local condi-tions, the presence of external electric and magnetic fields. A characteristic property of plasmas is their ability to transfer momentum and energy via col-lective motion. An example in this case, is the Langmuir waves where plasma electrons oscillate against a st

EPQ Policies Considering the Holding Cost of Raw Materials with Two-Level Trade Credit under Alternate Due Date of Payment and Limited Storage Capacity

Ghi-Feng Yen, Shy-Der Lin, An-Kuo Lee
The traditional Economic Production Quantity (EPQ) model focused on production process, used the ordering cost that includes relevant costs during the pre-production process. But, the ordering cost comprises the holding of raw materials that would affected by other factors would increase the total relevant cost, it cannot simply use the ordering cost to cover all. Therefore, this paper present

Design and Construction of a Telescopic Platform

Akinnuli Basil Olufemi, Olabaniji Taye Sola, Yakubu Anakobe Jimoh
A telescopic platform is equipment used in the Laboratory or Workshop to carry out different kinds of job on the ceiling e.g. fixing or replacing of electric bulbs, fixing of electric fans etc. it is also used to change streetlight on campus. Now that technology changes rapidly, the use of step ladders of different kinds with low reliability and quite a number of limitations should gradually be replaced by less expensive alternati

Methane Gas Emissions: Methods of Improving the Efficiency of the Biggest Landfill Gas Waste to Energy Project in the Middle East Installed in Amman, Jordan

Constantine Hadjidimoulas
In a world of increasing population and consumption, there is a pressing need to use our resources in the best possible way. This involves reducing the generation of waste, achieving high-quality recycling and efficient use of the residual waste for highly productive clean energy generation. A waste-to-energy facility may generate a range of energy outputs such as electricity, district heating, steam for industrial processes and m

Computer Aided System for Manufacturing Industries Economic Production Status Determination

Basil Olufemi Akinnuli, Eugene C. Kalu-Imo, Anakobe Jimoh Yakubu
Performance status has to do with profitability of manufacturing industries. Good performance brings about increase in productivity. There are in existence different models and software, but none has been able to develop software based on American Productivity Center model (APC). The strategic decisions required were identified as: Factor Productivity, Price Recovery and Cost Effectiveness ind
