EDXRF Spectroscopic Elemental Analysis for Efficacy of Kibabii University Sewage Treatment System

Yonah Situma, Jared Oloo Odhiambo, John Wanjala Makokha
Elemental analysis of sewage effluents in Kibabii sewage treatment system was achieved via Energy-Dispersive X-Ray Fluorescence (EDXRF) spectroscopy with the aim of assessing the efficacy of the treatment system. Concentrations of lead (Pb), mercury (Hg), cadmium (Cd) and arsenic (As) were measured based on clay soil “standards” in concentration range for Pb, Hg and As as 12.7 ppm, 14.3 ppm and 8.83 ppm respectively for certificat

A Battery Health Data Sharing Model via Blockchain

Peng Ding
According to the status quo of the electrical vehicle market, the numbers of re-tired power battery from the NEV (new electrical vehicle) would definitely lead to a big increase. And the key factor to evaluate the SOH (state of health) of the retired battery is to get the historical data to optimize the parameters of the models. But the truth is there are many restrictions in data access and sharing between the battery manufacture

Analysis of Spatial Sensitivity Based on Electrostatic Monitoring Technique in Oil-Lubricated System

Zelai Jin, Fuqiang Zhang
In this paper, for the detection of wear particles in lubricating oil roads, by an-alyzing the particle belt motor, a mathematical model of the oil circuit electro-static sensor considering the dielectric constant is proposed. At the same time, the concept of spatial sensitivity and visual field is introduced. The influencing factors of the position of the charged abrasive particles, the axial

Research on Human Vehicle Accident Reconstruction Based on AEB System

Yican Zhu
Accident reconstruction refers to the physical activity of inferring the accident process according to the traces left by the accident participants, the final posi-tion, the participation in the car damage and the injury of the participants, and then the testimony of the participants and eyewitnesses. It not only provides a basis for the identification of the faults of both parties, but also provides data support for accident prev

The Experiment of Acoustic Levitation and the Analysis by Simulation

Fuqiang Zhang, Zelai Jin
An acoustic levitation test bench was built to successfully suspend a small ball of a certain density. It was found that the smaller the diameter and density of the suspended sample, the easier it is to suspend. The diameter of the sample should not be larger than 1/4 - 1/3 of the wavelength of the acoustic wave. In addition, as the sound pressure increases, the sound flow also affects the sta

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

Research on Location Selection of Shared Vehicle Charging Station Based on Analytic Hierarchy Process and Fuzzy Evaluation Method

Rongxu Zhang, Bo Zhao
In view of the incompleteness of the methods used in the location selection of today’s shared car charging stations, the author proposes to combine the two methods of AHP and fuzzy evaluation to construct an evaluation index system and a fuzzy level evaluation model. The two alternative electric vehicle charging station addresses are comprehensively evaluated to achieve the most preferred address. Pr

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

Lightweight Study of Carbon Fiber Composite B-Pillar Based on Equal Stiffness Principle

Dongming Sun, Chao Tao
The replacement of carbon fiber reinforced epoxy resin matrix composite (CFRP) in the B-pillar of the body structure was discussed. Under the condition of ensuring crashworthiness, the lightweight application of B-pillar on the structural parts of the automobile was realized. Taking the steel B-pillar of a certain model as the prototype, CFRP is used for the same stiffness design, and the stiffness, crashworthine
