Research Paper (postgraduate) from the year 2019 in the subject Mathematics - Applied Mathematics, , language: English, abstract: In this paper, the Variational Iteration Method (VIM) and the Homotopy Perturbation Method (HPM) are applied to solve the non-linear differential equations. The Newell-Whitehead-Segel equation, the Burgers-Huxley, the Burgers-Fisher equation, the Fitzhugh-Nagumo Equation, the Fisher Type Equation are studied in different chapters and exact solutions are also obtained. A comparison is made between obtained results in finding the exact solution of the equation in order to present precision of the methods. The results prove capability and great potential of the methods as effective algorithms in order to obtain the exact solution of non-linear differential equations.
The full title of the HCM network project behind this volume is VIM: A virtual multicomputer for symbolic applications. The three strands which bound the network together were parallel systems, advanced compilation techniques andarti?cialintelligence witha commonsubstrate in the programminglanguage Lisp. The initial aim of the project was to demonstrate how the combination of these three technologies could be used to build a virtual multicomputer &#8212; an ephemeral, persistent machine of available heterogeneous computing resources &#8212; for large scale symbolic applications . The system would support a virtual processor abstraction to distribute data and tasks across the multicomputer, the actual physical composition of which may change dynamically. Our practical objective was to assist in the prototyping of dynamic distributed symbolic app- cations in arti?cial intelligence using whatever resources are available (probably networked workstations), so that the developed program could also be run on more exotic hardware without reprogramming. What we had not foreseen at the outset of the project was how agents would unify the strands at the application level, as distinct from the system level o- lined above. It was as a result of the agent in?uence that we held two workshops in May and December 1997 with the title &#8220;Collaboration between human and arti?cial societies&#8221;. The papers collected in this volume are a selection from presentations made at those two workshops. In each case the format consisted of a number of invited speakers plus presentations from the network partners.
When women from different parts of the world get together around a dining table what do they do? They tell stories. Each person sparks memories and imagination in the others until experience and invention are stitched into a rich patchwork. Join the Dining Table Writers; Vim, Urmilla, Rose, Marlene, Ki, Isabelle and Denise with their tales of a right of passage in traditional Sri Lanka, the art of making dahi in rural India and mysterious events in New Zealand. Uncover family secrets in a wardrobe in Mexico. Find out how a marriage is saved by timely advice from a Filipino nun, how living with the man you love in Lyon is quite a different matter from being a bride in rural Zimbabwe, and what one Oxford student came up against when seeking to visit the capital of seventeenth century Persia. Each story in this collection represents a highly individual interpretation of a situation or relationship where one culture bumps into another and the world tilts, if ever so slightly. Patchwork is the result of collaboration by seven writers and the proceeds will go to the Margaret McNamara Memorial Fund, a charity which awards grants to women from developing countries.

Angular-resolved optical scatterometry is a new promising technology for metrology in lithography for the construction of VLSI chips such as DRAMs and CPUs. In order to measure the geometry dimensions and material properties of markers and interconnect lines, one needs to solve Maxwell's equations for an electromagnetic scattering problem. The well known RCWA discretization method is too slow for 3D applications whence one takes resort to either a finite element discretization method or a volume integral method (VIM). VIM systems of equations can be solved faster than FEM systems of equations. This book focuses on an iterative solution of linear systems emanating from VIM. Each different linear system depends in a non-linear manner on several geometry, material and incoming light-wave parameters. For a typical 2D-periodic application on resist, VIM is a factor of 20 faster than RCWA. The VIM discretization leads to a dense complex linear system for the electric field for a 2D-periodic grating (3D Maxwell's equations). The coefficient matrix A is almost full but matrix-vector multiplications can be performed. Therefore; systems should be solved with an iterative solution method.

In 'Look Homeward, America,' Bill Kauffman introduces us to the reactionary radicals, front-porch anarchists, and traditionalist rebels who give American culture and politics its pith, vim, and life. Blending history, memoir, digressive literariness, and polemic, Kauffman provides fresh portaiture of such American originals as Catholic Worker founder Dorothy Day, regionalist painter Grant Wood, farmer-writer Wendell Berry, publisher Henry Regnery, maverick U.S. senators Eugene McCarthy and Daniel Patrick Moynihan, and other Americans who can't--or shouldn't--be filed away in the usual boxes labeled 'liberal' and 'conservative.' Ranging from Millard Fillmore to 'Easy Rider,' from Robert Frost to Mother Jones, Kauffman limns an alternative America that draws its breath from local cultures, traditional liberties, small-scale institutions, and neighborliness. There is an America left that is worth saving: these are its paragons, its poets, its pantheon.
This cookbook contains ready-to-use hacks to solve problems Vim users encounter daily, from personalizing Vim to optimizations that boost productivity. It does not cover basic use of the editor but focuses on making life easier for experienced Vim users. Vim is a highly configurable, open-source, multi-platform text editor that is included as standard in most Linux distributions. It can edit code in any language, has a scripting language that allows extensions to its functionality, and is editor of choice for many programmers. This book is up to date with the new features in Vim 7.0. Chapters cover: changing the appearance of the Vim editor; improved file and buffer navigation; using templates, auto-completion, folding, sessions, and registers; formatting text and code and using external formatting scripts; Vim scripts and scripting. Each recipe has a self-contained description of the task it covers, how to use it, the benefits of using it, and compatibility with earlier versions of Vim.
In Twas All Because of a Nose, Vim Nzabi paints a vivid tale of five friends drawn together by their commitment to one another and to a common objective. As they begin what is generally recognized as a search for fame and fortune, everything seems to go their way. Obstacles are quickly surmounted because of their determination to work together as a team while maintaining the strong bond of their friendship. Things, however, start to go downhill, when in the course of their journey they encounter situations that bring out a more individualized approach to problem-solving. What ultimately casts the five friends asunder is strangely enough, a runny nose. From that point on none obtain their goal, nor do any manage to make it back to their village. The story ends with a query that readers must resolve for themselves, a query as to how to build a better world where all retail their individuality while working for the common good.
