A Unified Equation of Interactions  [PDF]
Hasan Arslan
Open Journal of Microphysics (OJM) , 2011, DOI: 10.4236/ojm.2011.12005
Abstract: The aim of this study is to combine four fundamental forces in a single equation. Dirac equation is written by putting the Yukawa potential as a representation of the strong and gravitational forces. The ordinary terms seen in the Dirac Equation are treated as the representations of the electromagnetic forces. The Lagrangian of the weak local interaction of the charged particles is converted to the energy representation according to the virial theorem and is put in the equation. Thus four fundamental forces are combined in a unique equation.

The study will investigate the kinds of environmental management practices that are undertaken by companies in greening the supply chain and how these practices affect the environmental and operational performance of the companies. The study provides additional insight into the growing field of literature examining the relationships between environmental policies and operational performance.

Losses in Wireless ATM Networks  [PDF]
Hasan Harasis
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.53028

The standardized approach to Mobile ATM network handover is a hard backward or forward handover scheme with no guarantees for the integrity of the data stream. These handover functions are detailed in this paper and a more performant virtual connection handover protocol, using in-slot signaling techniques in order to facilitate loss less handover, is introduced. The QoS aspects related to this scheme are discussed and its OAM implementation is presented.

Introduction: Integrated Hospital Information System (HIS) is vital to decision making and plays a crucial role in the success of the organization. Computerization of the medical records and documentation has resulted in efficient data management and information dissemination for the users. Hospital Information System addresses the entire major functional areas of modern multi-specialty hospitals. The package enables improved patient care, patient safety, efficiency and reduced costs. It provides easy access to critical information, thereby enabling management to make better decisions on time. Aims: The short-term objectives of the on-line computerized system are to reduce costs and improve the accuracy and timeliness of patient care, accounting and administration, record keeping, and management reporting. The long-term goal is to build and maintain patient database for analysis of data to facilitate decision-making process. Methods: To run the system it requires some Hardware & Database for IT Department. The technique involves Patient Registration System, Finance & Accounts, Human Resource Management System, Laboratory, Out Patient Management System, and Inpatient Management System. Results: In the mid seventies, a complex was established at Shahbag area in the name of Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM). From 1982 BIRDEM was designated as the WHO collaborating centre for research on prevention and control of diabetes. It is first of its kind outside Europe. Now from 2000 BIRDEM has successfull developed & implemented some crucial part of HIS System like Patient Admission & Billing System, Finanace & Account System, Human Resourse Management & Payroll System, Store Inventory & Procurement Management System, Labrotary Management System, Assets Management System, Radiology & Imaging Management System. Conclusions: It can thus be seen that deploying IT can help

The Distances in the Stable Systems Due to the Virial Theorem  [PDF]
Hasan Arslan
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.44094

The virial theorem is written by using the canonical equations of motion in classical mechanics. A moving particle with an initial speed in an n-particle system is considered. The distance of the moving particle from the origin of the system to the final position is derived as a function of the kinetic energy of the particle. It is thought that the considered particle would not collide with other particles in the system. The relation between the final and initial distance of the particle from the origin of the system is given by a single equation.

The Dirac Equation with the Scattered Electron Including Extra Potential Energy Comes from the Virial Theorem  [PDF]
Hasan Arslan
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.44078

The scattering of electron by a photon is a well-known reaction in physics. In this study, the change in the electron’s energy after the scattering is taken into account. The previous works are searched. In order to take into account this change in the electron’s energy in the equation of motion of the electron, the Dirac equation is used with the virial theorem. The scattered electron kinetic energy which is given to the electron by the loss in photon’s energy is related to the potential energy of the electron by the virial theorem which states that the potential energy is two times of the kinetic energy in minus sign. A first time application of the virial theorem on a scattered electron by a photon is included to the Dirac equation.

Capital Budgeting Techniques Used by Small Manufacturing Companies  [PDF]
Maruf Hasan
Journal of Service Science and Management (JSSM) , 2013, DOI: 10.4236/jssm.2013.61005

Small companies account for 40% of Australian jobs and yet most of the studies on capital budgeting techniques have been focused on large firms. A mistake in their capital budgeting process could lead to disastrous consequences as they do not have the financial clout to recover from them. The purpose of the paper is to investigate where small manufacturing companies in Australia stand in regard to the use of capital budgeting techniques and risk analysis. The research concludes that while there is an indication of usage of the Payback Period with Discounted Cash Flow (DCF) techniques, there is a need for more frequent usage of risk analysis as well as management sciences which is found lacking in the capital budgeting process of small companies.

Some Possible Particles Decays from pp Collisions at LHC Experiment  [PDF]
Hasan Arslan
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.511103

Some of the possible decays of pp collisions at LHC experiment are considered. The vector bosons mediating in the electroweak interactions and right-handed leptons except neutrinos are assumed to be the most resultant particles from the pp collisions. Neutrinos and anti-neutrinos will be observed when one-double electron charged vector bosons are the resultant particles. The charge conservation is thought to be the dominant factor of these decays. The amplitude transitions for Feynman diagram of these decays are written.

Rerouting Schemes for Wireless ATM Networks  [PDF]
Hasan Harasis
Communications and Network (CN) , 2014, DOI: 10.4236/cn.2014.64024

In this paper, the Wireless ATM rerouting procedures are analyzed and categorized, based on a standard network topology, derived from the Wireless ATM reference model. A new operational concept for a mobile ATM network called Mobile Network Architecture based on Virtual Paths (MNAVP), in which the network nodes are connected to each other via pre-established permanent virtual path connections with fixed capacity assignments is being proposed and described. Finally, the handover hysteresis concept is introduced and a hysteresis gain is defined and calculated as the factor by which the handover rate is reduced through the use of the hysteresis.

Random Timestepping Algorithm with Exponential Distribution for Pricing Various Structures of One-Sided Barrier Options  [PDF]
Hasan Alzubaidi
American Journal of Computational Mathematics (AJCM) , 2017, DOI: 10.4236/ajcm.2017.73020
Abstract: The exponentially-distributed random timestepping algorithm with boundary test is implemented to evaluate the prices of some variety of single one-sided barrier option contracts within the framework of Black-Scholes model, giving efficient estimation of their hitting times. It is numerically shown that this algorithm, as for the Brownian bridge technique, can improve the rate of weak convergence from order one-half for the standard Monte Carlo to order 1. The exponential timestepping algorithm, however, displays better results, for a given amount of CPU time, than the Brownian bridge technique as the step size becomes larger or the volatility grows up. This is due to the features of the exponential distribution which is more strongly peaked near the origin and has a higher kurtosis compared to the normal distribution, giving more stability of the exponential timestepping algorithm at large time steps and high levels of volatility.
