The objective function maximizes the power of the wind turbine and the constraints are related to the rotor and tower costs. Rotor diameter and hub height are the variables which affect on power of the wind turbine, so we have considered them as decision variable in our mathematical model. By increasing rotor diameter and hub height the power of the turbine will increase but the costs don't let the infinitive increase in rotor diameter and height. The model applied for a typical case study and the results of solving the model for it have shown in the paper.

The proposed approach maximizes overall system reliability while minimizing system cost, system weight and volume, simultaneously, under nonlinear constraints. To meet these objectives, an adaptive hybrid GA–PSO approach is developed to identify the optimal solutions and improve computation ...

This study evaluates potential innovative energy-efficient wall systems for mid-rise (four to six storeys) wood-frame buildings in terms of thermal and structural performances. Regarding the thermal resistance performance, four wall systems are developed, installed in a full-scale test house, and examined, along with a baseline wall system, using the field data collected. The selection of the wall systems is based on current practice, structural analysis, pre-fabricability, and energy-efficiency. Several sensors are installed on each wall system to measure temperature, heat flow, and relative humidity. In addition, structural tests are conducted to determine the compressive loading capacity of the tested wall systems for both concentric and eccentric loads, where full-scale panels are constructed and tested in laboratory. As a general finding, all the tested wall systems achieved ASHRAE's minimum assembly R-value recommendation of RSI 3.45, where the I-joist wall system had the highest R-value, while the conventional wall system had the highest load-bearing capacity. This paper recommends I-Joist wall systems for their higher energy efficiency suggesting more future research on efficient end connections to achieve consistent structural performance.

Carpool is already an existing urban commuting mode with a modest modal share (around 9 percent in many North American cities). However, with increasing interests in considering Carpool as an effective TDM tool for long-term sustained TDM program, there is a growing interest in critical investigation of the carpool mode choice. This paper investigates the carpool mode choice in the context of overall commuting mode ...

Perturbation solution of stream function, the expression of skin friction coefficient and graphical results in absence of Hall current (Chiam, Int J Eng Sci 33 (1995), 429) are recovered as the limiting cases. It is found that unlike the solution obtained by , the present results are valid for weak and large magnetic parameters.

Mahapatra, A.S. Gupta, Stagnation-point flow of a viscoelastic fluid towards a stretching surface, Int. J. Non-Linear Mech. 39 (2004) 811] is solved analytically by using the homotopy analysis method (HAM). The results for velocity and temperature profiles are obtained. It is noted that the behavior of the HAM solution for velocity and temperature profiles is in good agreement with the numerical solution given in reference [T.R. Mahapatra, A.S. Gupta, Stagnation-point flow of a viscoelastic fluid towards a stretching surface, Int. J. Non-Linear Mech. 39 (2004) 811].

Transdermal administration has many advantages over the oral route for example: avoiding first pass metabolism thereby increasing bioavailability; and improving adherence. However, there have been several case reports of fatalities with transdermal administration due to a lack of patient and/or healthcare professional knowledge on safe application of patches . Research suggests an increased risk of administration errors with transdermal formulations compared with solid oral dosage forms . The aims of this study were to explore the views of healthcare professionals in order to determine their knowledge of transdermal patch use. This was part of a larger study that also investigated the disposal of patches.
