in this paper, the enhancement of vehicle stability and handling is investigated by control of the active geometry suspension system (ags). this system could be changed through control of suspension mounting point’s position in the perpendicular direction to wishbone therefore the dynamic is alternative and characteristics need to change. for this purpose, suitable controller needs to change mo...

this paper presents the results of a recent project of ikco’s research center to modify paykan 1600’s rear suspension mechanism with the purpose of improving comfort, stability and handling qualities. the car was originally equipped with a solid rear axle with leaf springs. by replacing the original mechanism with a three-link mechanism with panhard bar and coil springs, the ride comfort and ha...

background: this study was an investigation conducted at two oil palm plantations in slim river district, perak, malaysia on the prevalence of back pain among workers in the malaysian oil palm industry. many manual handling activities and tasks performed were not designed ergonomically, thus a high prevalence of musculoskeletal disorders was found among oil palm fresh fruit bunches (ffbs) manua...

background: inherent toxicity of cytotoxic drugs is the basis for their potential adverse risks from occupational exposure to the nursing staff. in iran, chemotherapy regimens are prescribed and administered according to the world updated protocols. but little is done regarding the protective standards in this field. methods: an observational cross-sectional survey was conducted among nurses wh...

The present paper discusses the development of a Markov model for performance evaluation of coal handling unit of a thermal power plant using probabilistic approach. Coal handling unit ensures proper supply of coal for sound functioning of thermal Power Plant. In present paper, the coal handling unit consists of two subsystems with two possible states i.e. working and failed. Failure and repair...

Despite comprehensive literature works on developing fitness-based optimization algorithms, their performance is yet challenged by constraint handling in various engineering tasks. The present study, concerns the widely-used external penalty technique for sizing design of pin-jointed structures. Observer-teacher-learner-based optimization is employed here since previously addressed by a number ...

The most frequent and expensive cause category of compensable loss is manual material handling (MMH). Casting workers who handle oxygen (O2) cylinders manually are at risk for work-related musculoskeletal disorders (WMSDs). The aim of this study was to assess manual handling of O2 cylinders by casting workers and to implement ergonomic intervention to reduce the risk of musculoskeletal disorder...
