OBJECTIVES The purpose of this work was to investigate the fitness of the existing truck seats for Bangladeshi truck drivers and suggest a guideline for drivers' seats based on their anthropometry. METHODOLOGY In this study, eight anthropometric measurements of 120 Bangladeshi truck drivers and seven seat dimensions of ninety trucks of three brands namely, TATA, ASHOK LEYLAND, and ISUZU were ...

A Neurointerface is a nonlinear filtering system based on Neural Networks that serves as a coupler between a human operator and a nonlinear system or plant that is to be controlled or directed. The purpose of the coupler is to ease the task of the human controller. A Neurointerface and a plant disturbance canceller have been applied to the steering system of a truck and trailer(s). The Neuroint...

This paper analyzes the feasibility of using cellular telephone location data to determine the geographic extent of trucks from intermodal facilities. The feasibility analysis includes three aspects: location technology, cell phone penetration, and truck tracking methodology. As the results shows, the cell phone location technology is able to provide accurate location data. It can provide updat...

This paper will present the structure of the new system, the control scheme and its performance test results. In this new system, the damper in the conventional refrigerator is replaced by an additional cooling fan Thus, it uses two cooling fans: one (F-fan) is to provide cooled air for freezing compartment (F-compartment) and the other (R-fan) is for refrigerating compartment (R-compartment), ...

Total or shared autonomous behavior is still an open challenge for service robots. An example of such system is FRIEND (Functional robot arm with user-friendly interface for Disabled people) (Figure 1). In the project ReIntegraRob care robot FRIEND will carry out all necessary manipulations for a completely paralyzed person who with support of FRIEND will be able to work in library. The task of...

The efficient and safe movement of freight is one of the important goals of urban transportation systems and vital to not only the local economy, but nationally as well. Given the importance of the freight transportation system, opportunities to utilize state of the art Intelligent Transportation Systems (ITS) technologies are increasing to improve the operation of the existing infrastructure t...

Maintaining the vaccine cold chain is an essential part of a successful immunization programme, but in developed countries faulty procedures may occur more commonly than is generally believed. A survey was conducted in a health district in central Italy to assess the methods of vaccine transportation and storage. Of 52 primary vaccination offices inspected, 39 (76.5%) had a refrigerator for vac...

the paper investigates into the vibrational characteristics of the truck chassis including the natural frequencies and mode shapes. truck chassis forms the structural backbone of a commercial vehicle. when the truck travels along the road, the truck chassis is excited by dynamic forces caused by the road roughness, engine, transmission and more. modal analysis using finite element method (fem) ...

A new model is presented to describe an irreversible absorption refrigerator, in which not only the irreversibilities of heat conduction but also the irreversibilities resulting from the friction, eddy and other irreversible effects inside the working fluid are considered. The influence of these irreversible effects on the performance of an absorption refrigerator with continuos flow is investi...
