Abstract In this paper we develop a method of characterizing the center-point curves for planar four-position synthesis. We predict the five characteristic shapes of the center-point curve using the kinematic classification of the compatibility linkage obtained from a complex number formulation for planar four-position synthesis. This classification scheme is more extensive than the conventional Grashof and non-Grashof classifications in that the separate classes of change point compatibility linkages are also included. A non-Grashof compatibility linkage generates a unicursal form of the center-point curve; a Grashof compatibility linkage generates a bicursal form; a single change point compatibility linkage generates a double point form; and a double or triple change point compatibility linkage generates a circular-degenerate or a hyperbolic-degenerate form.

This research’s aim is to giving the altervative disclosure index for shariah company.Researcher’s used shariah enterprise theory to make a new disclosure index, the first step is combine among disclsoure index are AAOIFI Index, Islamicity disclsore index and Islamic Social Reporting, then eliminate a few point form those index based on shariah etics, academic’s perspective and regulation in some countries. In other side, researcher’s used content analysis method in six countries are Indonesia, Malaysia, Bahrain, Qatar, Iran and UK. Result is a make new disclosure index that showing the God is a highest stakeholder in company, care about all stakeholder such as employee, nature, duafa etc. While, content analysis’ result shows new found things related unique policy in each company in some countries.

The text of Section 4 of the Twenty-Fifth Amendment is dense and requires careful unpacking. Section 4 allows a president to be displaced from power if the Vice President and a majority of the Cabinet declare that he is unable to discharge his powers and duties. The text then provides for the President to return to power. If the Vice President and Cabinet oppose his attempt, Congress is empowered to resolve any disputes. All of this is subject to specific procedural requirements and time limits. This chapter presents all of these details in both bullet-point form and with a comprehensive flowchart.

American Institute of Mining, Metallurgical and Petroleum Engineers, Inc. Abstract This paper presents the methods used to solve the finite difference equations which we developed in a companion paper (1). Various possible methods of solution are discussed. Experience has narrowed the numb of suitable numerical methods that are practical to three: Gauss elimination, successive practical to three: Gauss elimination, successive overrelaxation, and the iterative alternating direction implicit process. The final sections of the paper are devoted to a presentation of computational technique which are vital to actual use of each of the above-mentioned methods. FINITE DIFFERENCE EQUATIONS, THE MATRIX AND DEFINITIONS The final finite difference equation for pressure developed in Reference (1) is: pressure developed in Reference (1) is: ..........................................(1) All the terms are defined in the paper. Here, however, we have dropped the subscript denoting the pressure, p, as an oil pressure. Further breakdown requires definition of the numerical solution to be used. This paper describes the breakdown and solution processes most often used in the MUFFS program. Sufficient detail is given so that computer programming can be done. Contrary to popular opinion, economic simulation has been found to require the development of several solution methods, rather than relying on a single one. This requires that the computer subprogram for generating coefficients (A's and O's) be written as a distinct, separate entity to supply the coefficients in Equation (1). Furthermore, it is necessary to be able to obtain these coefficients automatically in column-by-column, row-by-raw, or point-by-point form, in any order required by a point-by-point form, in any order required by a numerical solution. Columns, rows, and points refer to the columns, rows, and points of the finite difference grid. A program that can generate coefficients in several forms is a simple but important concept, for it allows the easy insertion and modification of experimental methods. The computing inefficiencies that may be incurred within a general coefficient generator are small in comparison to the computing time saved by using the fastest of several solution techniques.
