in this paper a survey to determine the spring and damper settings of itm285 tractor’s cabin which ensured optimal ride comfort of tractor operator was conducted. analysis has been done in terms of root mean square acceleration response (rmsar) in one-third-octave band and international standard organization (iso). optimization was performed using particle swarm optimization (pso) method on a 2...

Energy inefficiency and underlying occupant discomfort associated with building thermal management systems have led to development of human-in-the-loop control system. Minimizing total energy consumption and maximizing comfort of all the occupants present is the major objective of such system based on human comfort feedback. However, the approaches proposed so far lack a built-in mechanism to e...

This paper describes an evaluation of the effects of three practical display design variables on air refueling boom operator estimates of distance, ratings of image stability and ratings of visual comfort. Eight combinations of three design variables were tested. Two separate display systems, one collimated and the other direct view, were set up such that stereopsis and head tracking could be t...

A predictive fuzzy control system that uses rules based on the experience of a skilled human operator is proposed and applied to achieve automatic stop operation for trains. In recent years, automatic train operation (ATO) systems using microcomputers to replace human operators have been developed for new transit systems, including subways, monorails and new public transit systems. Because the ...

Vehicle interior design directly relates to driver performance measures such as comfort, efficiency, risk of injury, and vehicle safety. A digital human is a convenient tool for satisfying the need to reduce the design cycle in order to save time and money. This paper presents a digital human environment, SantosTM, developed at The University of Iowa, and its assessment as applied to the interi...

The interaction of quadriplegic people with technology has been minimal in most cases and applications, which has generated a wealth of needs that affect the comfort and well being of the same. The purpose of this project is to design and implement a prototype to perform a scan and parameterization of the retina by image processing software to handle a given platform based on Windows.The operat...

To improve the safety and comfort of a human-machine system, the machine needs to ‘know,’ in a real time manner, the human operator in the system. The machine’s assistance to the human can be fine tuned if the machine is able to sense the human’s state and intent. Related to this point, this paper discusses issues of human trust in automation, automation surprises, responsibility and authority....

1 Sir: D the past decade, follicular unit extraction (FUE) has been become more and more popular in hair transplantation surgery.1 In China, almost half the patients undergoing hair transplantation choose FUE. Traditionally, the patient is placed in a prone position for occipital harvest or the lateral decubitus position for temporal and parietal harvest.2,3 However, the procedure of hair folli...

PURPOSE To test whether newer bilayer barium sulfate-bismuth oxide composite (XPF) thyroid collars (TCs) provide superior radiation protection and comfort during fluoroscopy-guided interventions compared with standard 0.5-mm lead-equivalent TCs. MATERIALS AND METHODS Institutional review board approval and written informed consent were obtained for this HIPAA-compliant study, and 144 fluorosc...
