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...

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...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Through the analysis of the current vehicle
reversing braking system, the paper introduces the safety hazard of the vehicle
in the reversing state and the
factors that affect reversing braking effect and the weakness of control
system. Aiming at the existing problems, designing and development of vehicle
reverse brake assist system. This method that uses the STC12C5A60S2 single-chip receives GPS vehicle speed signal, and reversing ...
