A computational model for inventory management and planning

The objective of the study is to determine the factors of the optimal level of merchandizing inventory. The study is based on a mathematical model. The results revealed some interesting findings. The most important conclusion is that the 'Usage of Material' or the Sales Volume is not the real determinate of the inventory volume. It is concluded in the model that the volume of inventories depends on the difference between the return on investment in the inventories and the rate of interest on short-term deposits. The traditional methods in cost accounting - Buffer Stock and Economic Order Quantity - have been reconciled with the profit maximization hypothesis.Inventory Control; Economic Order Quantity; Buffer Stock; Baumoul's Model; Optimization; Material Cost Accounting

When Military Restrain the Rule: Philosophy and Indications

It was concluded in the literature that military is merely a symptom of underlying political difficulties, a neutral force, which mechanically moves into the political area when a vacuum is created. Armed forces took control over the political management only in those economies where magnitude of military power was greater in relation with the size of economy: a higher defense expenditure to GDP ratio lead the control of political management by armed forces.Coupolgy; Economic Performance; Defence Expenditures;

Investigating the Effect of Fluid and Formation Parameters on Mud Cake Thickness, Filtration Velocity and Invasion Depth

Mud cake formation is a layer of mud emulsion that is formed from the drilling fluids during the drilling operation. Filtration process of drilling mud takes place as the drilling operation in carried out under a certain condition called overbalanced conditions, which means that the pressure of drilling mud injected is higher than the pressure of the formations. Due to this differential in pressure, drilling fluids will tend to be invaded into the porous part of the formation; where by the smaller particles of the drilling fluid will invade further into the formation, while the larger particles will accumulate at front surface of the pore size, creating a layer of mud cake. Understanding the behavior of mud cake thickness is important because it can reduce the mud circulation loss into the formation. Specifically, they are few objectives to be achieved within this project. They are i) to investigate the necessary parameters of the drilling mud properties in order to study the mud cake formation around the wellbore, ii)to investigate the necessary parameters of the drilling mud properties in order to study the mud cake formation around the wellbore. The formation permeability, mud cake permeability, porosity, mud filtrate viscosity, mud cake density, pressure, solid particle concentration in drilling mud, length of core and also the time measured have been identified as the main factors that will manipulate the mud cake thickness, filtration velocity and invasion depth of mud filtrate; meanwhile water-based mud drilling fluid is chosen for a shallow depth well under a static condition with constant pressure and constant low temperature. At the end of this project, it is expected that core with high cake permeability will result in higher mud cake thickness and filtration velocity compared to core with low mud cake permeability

MODELLING EMPIRICAL REGULARITIES FOR BANKING STOCKS IN PAKISTAN

This paper examines empirical regularities in terms of dayof-the-week anomalies for the banking stocks at the Karachi StockExchange for the period 1996 to 2008. Non normality of the datawith excess kurtosis suggested application of ARCH and GARCHmodels which proved uncertainty of returns from banking stocks.Nonparametric analysis of the data reveals evidence of day-of-theweekeffect in Pakistan as contrary to the findings of some of theprevious studies on Asia-Pacific markets. The evidence of the dayof-the-week anomaly might be attributed to the strength of thenonparametric estimation methods which are more robust whenthe data does not meet assumptions of normal distribution. Thestudy also finds relatively higher risk associated with returns onthe last day of the working week in general. Negative skewness formost of the return series indicates probability of yielding loss forinvestors in the banking stocks. Volatility test proves asymmetricresults for various banking stocks. Results of the nonparametrictests also reveal significantly different median returns on variousdays of the week for these stocks. The study finds out relativelygreater risk associated with Faysal Bank, Jahangeer Siddiqui Bank,Meezan Bank, National Bank and Prime Commercial Bank onMondays. For the days in the middle of the week the risks associatedwith the banking stocks are not asymmetric. For Friday, the closingday of the week, risk in respect of Bank of Punjab, Faysal Bank,Muslim Commercial Bank and National Bank is significantly large

Modernism in the eyes of T.S Eliot: break from traditional writings with literary forms and movements

This paper owes to uncover the modern aspects in the writings of T. S. Eliot. Modernism, a movement which erupts from philosophy and has a “self-conscious” break from traditional writings and worked with literary forms and movements. As a modernist he portrays about the standard of love, money minded people and self centered people. The research is entirely based on T. S. Eliot’s poetry and generalizing its work entirely which required depth study of his work and citation of the critic who entitled T. S. Eliot as a “modernist-poet”. This study is retro-spective which requires depth study in order to relate by the previous work done on generalizing T. S. Eliot as a modernist poet

Derivatif Radial Anomali Gravitasi Untuk Identifikasi Batas Vertikal Pada Lapisan Tunggal

The purpose of this study is to make and test radial derivatives for identification of single layers. Radial Derivatives are derivatives of gravitational anomaly values with respect to the horizontal distance in the radial direction of a particular point. The center of the derivative is chosen based on consideration as the center of the anomaly of target. Several synthetic single layer models have been made in the form of temple artifacts and water table changes over time. From these models, the gravity anomalies are calculated forward. Radial derivatives of these anomalies are performed to determine the vertical boundary of a single layer. Radial derivatives in a single layer of temple artifacts are useful for determining the boundaries of temple walls, so that the analysis of artifact excavation points can be better determined. Radial derivatives in anomalies in water table changes over time are useful for sorting shallow gravity anomalies which have significant value. The result of this research shows that radial derivative is able to detect boundary of buried temple and also boundary of water table. The advantage of the radial derivative method is that it is not necessary to re-measure if gravity data has been previously measured. In other words, this method is a software to review the further analysis that might have been done before
