A Study of Lighting Models for Automatic Detection of Regions of Interest and Surface Defects in Cast Metal Parts

George Kyriakides, Alexandros Daskalakis
This paper investigates the influence of ultraviolet (UV) lighting configurations on the automatic detection of Regions of Interest (ROIs) and the visual identification of surface defects in cast metal parts. A meticulous experimental setup was devised employing four UV light bars arranged in a rectangle, with varying combinations of active light sources. The study utilized the OpenCV library to automate the detection of mounting holes (ROIs) on the cast metal parts. Additionally, a visual inspe...

Study on the effect of Multiple Beds Operation Scheme for Performance Enhancement in Solar Heat-Driven Adsorption Chiller

Nusrat Jahan, Wahida Zaman Loskor, Md. Abdul Hakim Khan
The severity of the ozone layer destruction problem has called for rapid developments in environmentally friendly air conditioning technologies. Ongoing deregulatory efforts in the Organization for Economic Co-operation and Development (OECD) nations will ease the penetration of thermally activated heat pump systems. Absorption (liquid-vapor) and adsorption (solid-vapor) heat pump systems are thermally driven and have the advantage of being environmentally benign: both their ODP (Ozone Depletion...

Exploration on the New Direction of Fashion Design from the Perspective of Youth Subculture—Doll Clothing as Example

Shanshan Chen
Fashion design, as the name suggests, is an industry of designing fashion styles. Conventional clothing design and production take real human beings as the carrier. With the development of subculture, the words “doll circle”, “doll mother” and “doll clothes” have gradually come into the daily life of more and more people, and the word “doll” here does not refer to human children, but refers to dolls such as Barbie dolls. “Doll mother” is the name of the doll-raising group, and “doll clothes” is ...

Summary of Application of Vehicle Radiation Environmental Monitoring System

Jiawen Fan, Jie Xu, Xuan Qin
The vehicle-borne radiation environmental monitoring system is not restricted by time, location and weather, and in the event of a sudden nuclear accident, it can quickly enter the accident site and monitor the ambient reflectivity level and absorbed air dose rate at the first time. At the same time, the vehicle-borne data communication and processing system is used to transmit the real-time data to the platform of emergency monitoring and dispatching, which provides powerful technical support f...

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
