This study investigates the fire safety problem of a smoke detection system in terms of the probable response of light scattering photoelectric smoke detectors. In particular, response characteristics of the smoke detectors were studied experimentally in a test chamber described in UL268, with cotton wick generated fire smoke flowing at a velocity between of 0.5 ms and 3 ms. Measurements of a ‘...

Industry recognizes wireless sensor networks as one of the next major technical and economical shifts in automation and control systems. Industrial applications need performance assurances of wireless communication, which is hard to attain given the variability of the environment where such applications are deployed. In this paper, we quantify the impact of environmental conditions, namely temp...

The development of chassis dynamometer of hybrid vehicle based on CAN bus was studied. Chassis dynamometer of hybrid vehicle measurement methods and loading devices are analyzed, and laid the foundation for the resistance simulation of chassis dynamometer. Road resistance simulation on HEV chassis dynamometer is researched, getting electric quantity simulation type of chassis dynamometer drivin...

A finite element model was generated of a Søderberg electrode in a ferromanganese smelter. In this model, the casing and fins were modelled explicitly, and temperature-dependent material properties were included. A two-stage analysis procedure was used, the first part being a coupled thermal-electrical analysis using an applied DC current. As the casing material was non–magnetic, the DC current...

Pumping stations play an important role in agriculture development projects. Performance of the pumping stations should satisfy water requirements, and management. There are many problems face these pumping stations affecting their reliability and stability. Hydraulic problems are the most important item in the field of pumping station operation and design. Motivation of this research was prese...

Production and quality parameters of three commercial strains of cultivated mushroom Agaricus bisporus (Lange, Imbach) were evaluated. A correlation matrix was made between the main parameters. Blancochamp BL-40, a smooth white hybrid, generally produced the greatest number of mushrooms and provided the highest yield, and its firm mushrooms showed high protein, dry matter, and soluble solid con...

ABSTRACT The cultivation of button mushroom has reached a high technological level in developed countries and is associated with productivity indices. This involves not only compost production crop management but also the casing layer. Peat been established as one most appropriate materials for due to its excellent properties. However, good-quality peat available all countries, renewable, which...

This study was conducted to evaluate small-scale hot-water postpackaging pasteurization (PPP) as a postlethality (post-cooking) treatment for Listeria monocytogenes on ready-to-eat beef snack sticks and natural-casing wieners. Using a commercially available plastic packaging film specifically designed for PPP applications and 2.8 liters of boiling water (100 degrees C) in a sauce pan on a hot p...

Abstract As the main load-bearing component of aero-engine system, thin-walled casings have characteristics large size, complex structure, thin wall, and area. In addition to harsh working environment, it is necessary study applicable preventive measures contain high-energy fragments ensure flight safety. The load formed by axial impact circumferential torsion exerted turbine rotor on exhaust c...
