In this paper, the dynamic multivariable model of the wheelchair system is obtained including the presence of transportation lags. The triangular diagonal dominance (TDD) decoupling technique is applied to reduce this ...

This paper explains how Indirect Evaporative Cooling (IEC) uses water as a refrigerant. This water refrigerant may be seen as part of the rain cycle, whereby the environment (not a heat pump) returns water as the refrigerant ...

An urgent need for creative, sustainable approaches, which minimise the environmental impact of conventional Portland Cement (PC) -based construction materials, is recognised throughout the world. In recent years intensive ...

The use of adjustable Amplitude Frequency Characteristics (AFC) approach is a new concept in vibration mitigation, which is developed from frequency detuning technique used in vibration protection against resonance. This ...

In this paper an investigation is carried out to see if it is possible to assess the condition of a rotor by clamping it in a DC-current-injection rig and measuring voltages in bars at regular intervals down the axial ...

This study investigates the eflects of vegetation on soil matric suction and ground deformation. This paper highlights the inter-related parameters contributing to the development of a conceptual evapo-transpiration and ...

One-step delay in digital implementation of direct torque controlled (DTC) AC motor drives leads to large torque ripple and low switching frequency. Two remedies are proposed in this paper to eliminate the one-step delay. ...

Unmodeled systematic and nonsystematic errors in robot kinematics and measurement processes often cause adverse effects in several autonomous navigation tasks. In particular, accumulated sensor biases can render ...

This document presents an analysis of the factors that influence the network topology in a broadband mobile wireless as hoc networks moving on platforms. This paper focuses on studying the topology for networks where the ...
