Download file to see previous pages The number of CAD systems has magnanimously risen over the recent past. Four categories described the systems, which are Wireframe CAD, Surface CAD, 2D CAD, and Solid CAD. Nonetheless, this paper narrows down its focus to solely Surface modeling although in a number of instances appropriate comparisons, more especially to solid modeling will be considered. Before delving deep in the subject, it is vital to highlight what surface modeling is all about.
According to Allègre et al. (2010), surface modeling generates a model which has minimally ambiguous representation as compared to wireframe although non-comparable to solid modeling which often provides an increasingly realistic perspective. Surfaces and curves are often at the center of their construction. This is a definitional approach accepted by (Lin, Ball, & Zheng, 2008) who nonetheless simplifies it by defining surface modeling as a component’s skin, inclusive of the surfaces and edges. Put in another way, surface models are three-dimensional (3D) models which lack thickness (Tobias, 2009). An important thing which should be emphasized about surface modeling is its representation of not just the surfaces and edges but the shape design as well. Engineers define as surface as a mathematical presentation of the skin of a component. Generally, B-Splines and Beizer mathematical methods are common tools in controlling curves when undertaking surface modeling. Basically, surface models have neither thickness nor volume and their construction starts with the construction of wireframe entities which are then corrected appropriately using a relevant surfacing technique. A sample surface model illustrated below:
It is important not to confuse surface models with thick models which have some mass properties in them. As earlier mentioned, surface models have no thickness at all, as compared to the thick and solid. ...Download file to see next pagesRead More

### Surface analysis

...?Surface Analysis and Materials Science Introduction Klauber and Smart (2003) declared that the primary objective of materials science is to develop materials which possess specific mechanical, electrical, magnetic, optical, thermal, and chemical properties. Such materials are required to be exhibit stability under normal environmental conditions. The behaviour of a material’s surface as it reacts to its environment is important because it reveals how well-suited a particular materials performs its intended function. For example, corrosion in metal is prevented through the use of specific chemicals; various optical effects on lenses may be done through special coatings; and automobile emissions are...

...to the desired size and shape after completing the treatment. This technique is used in situations where certain parts of the metal, for example, the gear wheel, need to be hardened to reduce wear. The other sections of the metal can be left tough and fatigue resistant. Advantages of Carburizing 1. It guarantees higher resistance to corrosion and wear because of the depth of cases; it is possible to achieve depths greater than 0.3 inches. 2. It results in steel with greater strength than other surface hardening techniques. Disadvantages of Carburizing 1. The high temperatures involved lead to distortion, thus resulting in losses and increased expenses. 2. It takes long to complete a single carburizing...

She got her B.S. nursing and then a Masters in psychiatric nursing. Later she received a Doctorate in educational psychology. She wrote a paradigm and Grand theory for nursing which encompassed many mid-range theories and applied clinical practice, educational programs and research (Erickson, Tomlin, & Swain, 2005). The theory is named Modeling and Role Modeling. This paper will discuss the theory developed by Erickson as well as how the theory can be integrated into various...

...oxide fuel cell (SOFC). PEM fuel cells have high power density and low operating temperature, so it warms up and starts generating electricity relatively faster. The SOFC operates at very high temperatures; reliability becomes an issue unless in continuous use. There are many hybrid models currently on the market. Besides for the Honda Insight and Toyota Prius, there is the 2007 Honda Civic Hybrid; and the 2004 Ford Escape SUV hybrid, the first SUV hybrid. It may be very soon when we will see hydrogen-petrol hybrids on the streets of Western cities. What are the pros and cons of hybrid cars? Possible cons include the...

### Hybrid cars

...when they reduce the drag on a vehicle. The up front area of hybrid cars is made with aerodynamics in mind, which makes it easier for a vehicle to move. Additionally, since the gasoline requirement for hybrids is less, the fuel tank is made smaller and this reduces the overall weight of the car, consequently conserving energy. Reduced pollution: Due to the fact that hybrid cars do not use gasoline all the time, the amounts of emissions they release into the air are reduced. According to Fitzgerald, “hybrid cars do reduce emissions by up to 90% and the 2010 model Prius…., claims to cut petrol consumption by 50%” (2009, p. 14). Lower running costs: The...

... Bauhaus Concept: Design or Rationalism The ideas of Bauhaus, a thought-provoking project designed to show that design is not worth considering, were defeated, as it may seem at a first glance. It is only partially right. Rationalism and striving for conveniences and organization in everyday life are important, as they can save much useful time and can help economize living space and arrange the things the way they will not create obstacles for living. One of the Bauhaus ideas, the idea that a home is a machine for living and producing things, did not survive long because of such simple reason as human soul. It is natural for human to seek for beauty, and it is impossible without designing work. It is preferable to sit... Bauhaus Concept:...

Introducing the constant of proportionality, the resistance, The resistance (R) of an object is defined as the ratio of voltage across it (V) to current through it (I), while the conductance (G) is the inverse: R=V/I G=I/V=1/R Where I am the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohms law states that the R in this relation is constant, independent of the current. For a wide variety of materials and conditions, V... PROFFESSOR...
