Differential operator

for solving linear differential equations with variable coefficients. The solutions usually take the form of power series; this explains the name Power series method. We review some special second order ordinary differential equations. Power series Method is described at ordinary points as well as at singular points (which can be removed called Frobenius Method) of differential equations. We present a few examples on this method by solving special second order ordinary differential equations. Key words

neutralize the advantage. There are two main types of competitive advantages: comparative advantage and differential advantage. Comparative advantage, or cost advantage, is a firm 's ability to produce a good or service at a lower cost than its competitors, which gives the firm the ability sell its goods or services at a lower price than its competition or to generate a larger margin on sales. A differential advantage is created when a firm 's products or services differ from its competitors and are seen

Introduction Many physical phenomena in stationary condition such as electrical and magnetic potential, heat conduction, fluid flow and elastic problems in static condition can be described by elliptic partial differential equations (EPDE). The EPDE does not involve a time variable, and so describes the steady state of problems. A linear EPDE has the general form as presented in Eq. (1), where a,b,c are coefficient functions, the term f is a source (excitation) function and u is the unknown variable

In 2014, a group of scientists; including Nichola C. Garbett, Michael L. Merchant, C. William Helm, Alfred B. Jenson, Jon B. Klein and Jonathan B. Chaires, discovered an effective and mind-blowing discovery — to use a heat profile from a person’s blood, known as a plasma thermogram and the use of calorimetry and heat formation to identify whether an individual is suffering from symptoms of cervical cancer, determined through the shape of their heat profile graph. Each of these scientists are actively

\subsection{NIPG DGFEM Superconvergence 2011} Now that the continuous standard Galerkin solution over a quasi-uniform mesh may oscillate as $\epsilon \to 0$. An alternative tool will be a discontinuous Galerkin (DG) method where the oscillation can be avoided provided that an appropriate mesh refinement is applied, to capture the boundary layer behavior. The origins of the DG methods can be traced back to the seventies where they had been proposed as variational methods for numerically solving initial-value

Background The Holy Cross Mountains are a Paleozoic fold belt composed of a series of map scale folds with a variable wavelength (1 to over 8km), amplitudes (0.2 to 1km) and geometry wise the fold are open to isoclinal (orientation of the fold axes is 95-120 degree). It’s located in the contact zone between the Paleozoic platform and the East European Craton. Lysogory and Kielce are the two regions considered as structural facies units and also fold zones for the tectonic sub-division. 1926 is

1. Introduction 1.1 ANSYS ANSYS is a software package that allows various simulations in a range of different fields and industries to be modelled and analysed. The main fields within the program include, computational fluid dynamics, structural mechanics, and electromagnetics to mention a few. The use of this software allows an individual or business to test various cases of product use, eliminating the outlay cost of building and testing many prototypes. This saves on time and costs and is a lot

Drug content estimation Spray dried powder samples (5 mg) were weighed accurately and dissolved using a mixture of water/ methanol (80:20% v/v) in a 100 mL volumetric flask. The flasks were shaken at room temperature for 60 min on an orbital mixer incubator (Ratek Instruments Pty. Ltd., Victoria, Australia) at a speed of 200 rpm followed by bath sonication using an ultrasonic cleaner (Misonix Inc., NY, USA) for 15 min. The solutions were filtered, and the drug content of filtrates was quantified

I. Concept – Properties of the polymers are determined by the molecular structure that comprises these polymers (Structure-Property Relationships). A precise conclusion of the properties can be obtained if we have exact information about its chemical structure and the force that prevails between the atoms and the molecules (intermolecular and intramolecular forces) Structure of the polymer can be described at various levels. From the chemical structure (i.e. its molecular formula) it can be determined

The determintaion for seeking my future in Structural Engineering comes from my interest in Structures after I joined undergraduate studies in Civil Engineering at Kathmandu University. I’d found my interest growing already in Civil Engineering when I was in high school. I was following works of my brother while he was studying Civil engineering. I could understand and draw Plan and sections before I was got enrolled in undergraduate studies. During my undergraduate studies, I particularly enjoyed
