Design and construction of a two dimensional duct equipped with a wave generator and a variable coastal slope and an ocean wave energy conversion system (OWC)

The aims of this thesis were evaluation the type of wave channel, wave current, and effect of some parameters on them and identification and comparison between types of wave maker in laboratory situations. In this study, designing and making of two dimension channels (flume) and wave maker for experiment son the marine buoy, marine building and energy conversion systems were also investigated. In current research, the physical relation between pump and pumpage and the designing of current making in flume were evaluated. The related calculation for steel building, channels beside glasses and also equations of wave maker plate movement, power of motor and absorb wave(co astal slope) were calculated. In continue of this study, the servo motor was designed and applied for moving of wave maker’s plate. One Ball Screw Leaner was used for having better movement mechanisms of equipment and convert of the around movement to linear movement. The Programmable Logic Controller (PLC) was also used for control of wave maker system. The studies were explained type of ocean energies and energy conversion systems. In another part of this research, the systems of energy resistance in special way of Oscillating Water Column (OWC) were explained and one sample model was designed and applied in hydrolic channel at the Sheikh Bahaii building in Azad University, Science and Research Branch. The dimensions of designed flume was considered at 16 1.98 0. 57 m which had ability to provide regular waves as well as irregular waves with little changing on the control system. The ability of making waves was evaluated in our designed channel and the results were showed that all of the calculation in designed flume was correct. The mean of error between our results and theory calculation was conducted 7%, which was showed the well result in this situation. With evaluating of designed OWC model and considering of changes in the some part of system, one bigger sample of this model can be used for designing the energy conversion system model. The obtained results showed that the best form for chamber in exit position of system, were zero degree (0) in angle for moving below part, forty and five (45) degree in front wall of system and the moving forward of front wall keep in two times of height of wave.

Rethinking Le Corbusier: Urban Design and History

It is generally assumed that Le Corbusier’s urban planning made a break with the past, and that the public spaces designed by him had nothing to do with anything that existed before – a conviction fostered by both the innovative character of his proposals and by the proliferation in his manifestos of watchwords that mask any evocation of the past – words like civilisation machiniste, l’esprit nouveau, l’architecture de demain. However, in his writings, Le Corbusier often mentioned the powerful analogy that exists between the architecture of other times and the logic of modern production. Vers une architecture, for example, contains a mixture of photographs showing silos, cars, aeroplanes, ships (i.e. the fruits of 19th and 20th century civil architecture and mechanical engineering) alongside photographs of Greek and Roman buildings. While Le Corbusier, at the end of the 1920s, claimed “I have only one teacher: the past; only one education: the study of the past”, a series of sketches in the first volume of the Œuvre complète, done during his youth at the archaeological sites visited during his Grand Tour, shows that his interest in the past went far beyond a simple reference.

Guidelines on building design and operation to minimize air quality impacts from major roads in transit oriented development

Poor air quality has a huge detrimental effect, both economic and on the quality of life, in Australia. Transit oriented design (TOD), which aims to minimise urban sprawl and lower dependency on vehicles, leads to an increasing number of buildings close to transport corridors. This project aims at providing guidelines that are appropriate to include within City Plan to inform future planning along road corridors, and provide recommendations on when mitigation measures should be utilised.
