Occupational safety model in maintenance operations: a case study of a service company
… model was implemented in medium and low voltage electrical work, where a higher level of risk was identified through the risk matrix, specifically in the maintenance activities of medium and low voltage electrical panels, as well as in illuminated signs. Regarding the continuous IPERC matrix, it …

An Approach to Automotive Electrification and Testing
… charging capability. This paper will cover the electrical work performed on the vehicle during the summer prior to year three of the competition, EcoCAR 2 year three, and preliminary work for EcoCAR 3 year one competition. The main focus of this paper will be on the electrical system integration …

Flow of Entropy in Equilibrium and Non-Equilibrium Quantum Systems
… involved in the interconversion of entropy into electrical work and the converse, in a range of systems that define the current and coming technological revolution, those of open quantum systems in and out of equilibrium. Simple and comprehensible formulas for global and local heat and entropy …

Electrical characterization of large-area donor-acceptor molecular junctions
The electrical properties of five different donor – bridge – acceptor large-area monolayer molecular junctions show current rectification. Langmuir-Blodgett deposition onto thermally evaporated gold yielded four out of the five monolayers. The fifth system was as a monolayer formed by self-assembly …

Indirect measurement of the electrocaloric effect
… But it is not designed to criticise prior work. Rather, it is intended to discriminate between reliable experimental procedures and those less convincing. This is a line of research with important technology transfer possibilities, and hence the numerical values of electric cooling must be …

Feasibility of using power steering pumps in small-scale solar thermal electric power systems
… non-dimensionalized and used to predict the ORC working fluid's properties. Unfortunately, deionized water caused the power steering pump shafts to seize; the efficiencies were below anticipated and the pumps were unable to operate under the specified pressures. It was discovered, after WD-40 was …

An air-to-air heat pump
… on their respected stands. The piping, duct, and electrical work were completed. ‘The design and construction of each of these phases was done with emphasis on clarity, simplicity, and ease in operation and maintenance. The valves numbered 1 through 12 are the control valves. The system is …

A history of Ohm's Law: Investigating the flow of electrical ideas through the instruments of their production
This thesis takes a deep dive into the electrical work of Georg Simon Ohm. It is tightly focused on the period 1825-1827 when he developed and published the famous law we now think of as “Ohm’s law”. This work differs from previous studies of Ohm’s investigations by putting material culture at its …
