expressed, Stokes’theorem can be described by considering a surface S having a bounding curve C. Here, v isany sufficiently smooth vector field defined on the surface and its bounding curve C. It isvery important to emphasize the fact that C is any closed curve in three dimensional spaceand S is any surface bounded by the said curve C. Mathematically this is written as: Page 22.257.4 ∫ (∇ × v) • dS = ∫ v • dx s cIn addition, it is important to note that when one considers only a two-dimensional space,Stokes’ theorem effectively becomes Green’s theorem.Another method of
application, starting at $14,000 for a model with a maximumflow velocity of 0.3 m/s and a 70 in2 test cross-section, much less than the 400 in2 test cross-section needed.This paper describes the conversion of a pre-existing 24 foot diameter 4 foot deep above-groundpool into a variable flow-rate “water tunnel” facility using $500 of additional equipment. Steadystate flow rates of 0.89 m/s are achieved using an 80 pound thrust (rated) trolling motor poweredby a pulse-width-modulated motor controller drawing approximately 970 W of electrical power.Calculations indicate that approximately 400 pounds of rated thrust will be required to reach ourgoal of 2.0 m/s flow rates near the outer edge of our pool river simulator.1 Introduction and Motivation1.1
America‟s energyproduction; not only because of the region‟s market liberalization, governments push for clean energy andinvestment in new sustainable technologies, but also because of the enormous untapped solar, wind, andbiomass (among other renewable energy sources) potential in the area. Even though there exists largedisparities in terms of availability of conventional sources, Latin America is endowed with abundantrenewable energy resources, which until now are grossly underutilized [10] (See Fig. 1, 2, and 3). A key aspect in explaining the fast evolution of DG sources is the development of promotion programs,subsidies and compensation mechanisms, points which countries in Latin America are beginning topromote and implement in order to

the world‟s fastest growing renewable energy where the average annual growth rate ofwind turbine installation is around 30% during the last 10 years [10]. Several researchers haveinvestigated the feasibility of wind energy utilization in the Persian Gulf region [17–21].Figure 9 shows the regional installed wind power where the growth of Asia is significant but notin the Middle East including Qatar. Fig. 10. Global annual installed capacity 1996-2007 [10] Fig. 9. Annual installed capacity by region 2003-2007 [10]A major challenge in using wind as a source of power is that wind is intermittent and it does notalways blow when electricity is needed. Wind energy cannot be stored (unless batteries areused); and
with a 1992 manual Chevy S-10 pickup as shown in figure 1. This vehiclewas chosen as its bed gave us an easy location to store batteries, its manual transmission allowsfor an easier adaptation to an electric motor, and it was readily available.We calculated the power required to reach a number of different top speeds as well as the rangeassociated with them based on the weight of the truck, weight of the proposed electricalcomponents, dimensions, and the desired range. Figure 1: The Manual Chevy S-10pPickupFirst, to determine the power needed to reach the targeted highway speeds, the forces acting onthe moving truck were considered. The truck dimensions and weight were determined after theconversion and are shown in

“conceptresilience” (faith backed by depth of knowledge) to pick the right ideas from what such aninstructor would explain, the student usually comes back with the sage advice that “s(he) said itwon’t work”. A simple example might be illustrative. It came from sending students to ask theseemingly straightforward question: “What value of efficiency should I use as being possible, forconversion between AC line power and beamed microwave power?” To the unwary aerospaceengineer, the answer to this seems to be what one might describe as “antenna efficiency”.However, reality is far more complicated.It quickly becomes evident that beaming large amounts of power is not a popular subject inmodern textbooks. Antenna design issues generally drive quickly towards the
trained human resources to support this national effort.Solar photo voltaic technologies have been increasing its participation because they rely on themature and powerful semiconductor industry, and also because they offer unique operationalcharacteristics which the residential and commercial sectors can use for distributedgeneration.This environment has created within Universities a strong interest from students forthe acquisition of knowledge on Renewable Energy. Correspondingly, Faculty has madesignificant number of proposals to develop on-site low power photovoltaic generation resources,as a response to the student´s interest.This paper describes the work done during 2010 at the Electrical Engineering Department of TheUniversity of Texas Pan
