INTRODUCTION Space Vector Modulation became a standard for the switching power converters and important research effort has been dedicated to this topic. Tens of papers‚ research reports and patents were developed in the last ten years and the theory of Space Vector Modulation is already

How Disease is Spread by Vectors In medical science or biology‚ a vector refers to an agent (microbes‚ animals or person) that does not cause disease by itself but helps in transmitting the pathogens that cause disease from one host to another. In this sense‚ the host could be humans‚ animals or plants. These vectors have contributed to the epidemic of so many diseases. Different diseases are transmitted by different vectors but some ailments share common vectors. For instance female anopheles

The main application of plasmids is as cloning vectors in gene cloning. In gene cloning‚ a fragment of DNA‚ containing the gene to be cloned is inserted into a circular molecule called the “vector” to produce recombinant DNA molecule. Plasmids are one of the most commonly used “vectors” for this purpose. They transport the gene into a host cell‚ such as a bacterium‚ which is said to be transformed with the recombinant molecule. Here‚ these plasmid vectors multiply‚ producing numerous identical copies

1. Gradient of a scalar field function Scalar Function: Generally‚ What Is Scalar Function? The Answer Is that a scalar function may be defined as A function of one or more variables whose range is one-dimensional‚ as compared to a vector function‚ whose range is three-dimensional (or‚ in general‚ -dimensional). Scalar Field When We Talk about Scalar Field‚ We Are Talking about the Scalar Function Being Applied to a Space (More like Euclenoid Space etc) or‚ a scalar field associates

The Vector equation of a plane To find the vector equation of a plane a point on the plane and two different direction vectors are required. The equation is defined as: where a is the point on the plane and b and c are the vectors. This equation can then be written as: The Cartesian equation of a plane The cartesian equation of the plane is easier to use. The equation is defined as: One of the advantages to writing the equation in cartesian form is that we can easily find the normal

Computer as a tool Nicholas O. Williams Raster Images vs. Vector Images Assignment: Discuss the differences‚ advantages and disadvantages. There are two major types of images used by graphic design programs‚ they are called Vector and Raster images. This paper will seek to highlight the many differences‚ advantages and disadvantages respectively. Raster images are complex renderings made up of thousands of little dots or pixels. The word raster has its origin in Latin which means ‘rake’

Vector aeromotive corporation case study Vector Aeromotive Corporation was a company which designed‚ manufactured and sold exotic sports cars. Vector was the only U.S.-based manufacture of exotic sports cars‚ and his major competitors were Ferrari and Lamborghini. Gerry Wiegert is the President and founder of this company. In 1987‚ the board of directors was formed with three directors. This case shows events happening between the board and President Gerry. In March 1993‚ the company’s financial
