A hybrid heat-pipe cooling structure for the permanent magnet synchronous motor electric vehicles was analyzed in this paper to effectively equalize axial temperature rise and reduce average of each heat-generating component motor. field calculation method based on an equivalent thermal network proposed save computing resources analyses motors. The results were verified against simulation compu...

This paper investigates the inspection-of-pipe topic in a new framework, by rotation around pipe, peculiar to industrial sites and refineries. The evolution of ultimate system requires prototype design preliminary tests. A benchmark has been designed built mimic with main purpose assessing different types rotors control systems. presents mechatronics package including mechanical machining, elec...

The nanoparticles formed in motor vehicle exhaust have received increasing attention due to their potential adverse health effects. It has been recently proposed that combustion-generated ions may play a critical role in the formation of these volatile nanoparticles. In this paper, we design an experiment to measure the total ion concentration in motor vehicle engine exhaust, and report some pr...

in this study, using sound created by wheat grain passing through a pipe, wheat flow rate was measured. the developed device consists of a hopper, metering device, sound sensor, delivery tube, dc motor and power supply. several wheat mass flow rates were tested and the sound signal created by the passage of the grain through the discharge tube was measured and transferred to a computer using da...

Spatially regulated transcription of the pipe gene in ventral cells of the Drosophila ovary follicle cell epithelium is a key event that specifies progeny embryo dorsal-ventral (DV) polarity. pipe encodes ten putative protein isoforms, all of which exhibit similarity to vertebrate glycosaminoglycan-modifying enzymes. Expression of one of the isoforms, Pipe-ST2, in follicle cells has previously ...

Objective: To assess characteristics of asbestos exposure in respiratory cancer patients in Lithuania. Methods. Information on occupational exposure to asbestos was collected by personal interviews and occupational characteristics were evaluated among 183 lung cancer and mesothelioma patients with cumulative asbestos exposure ≥0.01 fibre years hospitalized at the Institute of Oncology, Vilnius....

This paper addresses the dimensional synthesis of an adaptive mechanism of contact points ie a leg mechanism of a piping inspection robot operating in an irradiated area as a nuclear power plant. This studied mechanism is the leading part of the robot sub-system responsible of the locomotion. Firstly, three architectures are chosen from the literature and their properties are described. Then, a...

A distributed Brillouin fiber sensor has been employed to detect localized pipe-wall buckling in an energy pipe by measuring the longitudinal and hoop strain distributions along the outer surface of the pipe for the first time. The locations of the localized pipe-wall buckling are found and distinguished using their corresponding strain-load data. The formation of the buckling process for the c...

Buried water and gas pipe systems form part of critical infrastructure providing essential services to the community. In many global population centres including in Australia, this vital infrastructure has been installed several decades ago, and dealing with frequent pipe failures become a major problem. There are clear evidences that pipe failures significantly depend on pipe strains induced b...
