A cyber-physical system (CPS) usually contains multiple control loops, each responsible for controlling different physical subprocesses, that run simultaneously upon a shared platform. The foremost design goal for CPSes is to guarantee system stability and control quality with limited cyber resources. We show, via an in-depth case study, that two inter-related design parameters — sampling perio...

The maximum allowable biological concentration of a toxic substance is the highest concentration which can be found in a biological medium without damage to health. The biological materials rna y be examined for: (a) the toxic substance itself; (b) a product of the metabolism of the toxic substance in the body; (c) a substance derived from the physiopathological activity of the toxic substance;...

gorganrood river is one of the three main rivers in golestan province have a basic role in golestan water supply. to study gorganrood water quality and estimating maximum allowable pollutant, water quality data was used from 8 stations. purification of this river has been studied by two methods: statistical and experimental methods. each method showed that the gorganrood river at present condit...

Risk assessments are used to inform decision-making in hazardous systems. The process involves highly technical steps such as quantifying uncertainty and it is typically carried out by subject matter experts with a robust engineering background. also value-loaded selecting the risk acceptance criteria for evaluating risks. In built environment, support performance-based design of late, these ha...

This paper develops a computational technique for finding the maximum allowable load of mobile manipulators for a given trajectory. The maximum allowable loads which can be achieved by a mobile manipulator during a given trajectory are limited by the number of factors; probably the dynamic properties of mobile base and mounted manipulator, their actuator limitations and additional constraints a...

On separate days, 6 highly trained participants performed psychomotor tests while breathing for 60 min 3 carbon dioxide (CO(2)) mixtures (room air, 3% CO(2), or 4% CO(2)) prior to, between, and following two 15-min treadmill exercise bouts (70% VO(2)(max)). Each individual was extensively practiced (at least 4 days) before testing began, and both gas conditions and order of tasks were counterba...

Quartz is a human carcinogen and a causative agent of silicosis. Exposure levels often exceed exposure limits in the construction industry. The need for effective control measures is high, but the complex structure of the construction industry, the variability in sources of exposure and the frequent changes of worksite makes it difficult to implement even simple and potentially effective contro...
