Value engineering and process re-engineering and their role in reducing costs
...Show More Authors

تسعى المحاسبة الى مسايرة القفزات الهائلة والمتسارعة في تطور العلوم الصرفة والتطبيقية والتقدم التكنولوجي، والتي ادت على ظهور مفاهيم جديدة الغت مسلمات وبديهيات كانت سائدة لمدة طويلة، فعلى سبيل المثال: كان مخزون المواد الاولية والبضاعة التامة في المؤسسات الصناعية او التجارية يشكل العمود الفقري لها بتكاليفه ومشاكله، حتى اذا ما جاء نظام (JIT) الغى بتطبيقاته هذه المفاهيم واعتمد مفهوماً جديداً هو (الانتاج من اليد الى الفم)، وان مفاهيم الكلفة والتسعير تخلخلت وتقادمت بظهور فلسفة سوق المنافسة الحرة والعولمة، واصبح الزبون هو القاسم المشترك والاساس لنجاح كل المؤسسات او فشلها فإذا لم يرض الزبون بمنتج ما بسبب تغير اذواقه او ميله الاستهلاكي فلا فائدة من انتاج البضاعة حتى لو كانت بأساليب مثالية. وقد كان للتطورات التكنولوجية اثر كبير في السلع والمنتجات فظهور منتجات جديدة في السوق يؤدي الى تزايد الطلب على سلعة معينة، وتخفيض الطلب على سلعة اخرى. ولذلك فقد ظهرت مسألة خطيرة في هذا المجال وهي الاندثار بالتقادم او ما يسمى بالاندثار التقني. فالقفزة النوعية تتمثل في ان هذا الاندثار يؤدي الى صرف مبالغ هائلة في موضوع البحث والتطوير لغرض تصميم منتجات جديدة تساير اذواق المستهلكين، اذ اصبحت السلع تتقادم شهرياً او خلال مدد قصيرة.

ان الاساليب الادارية الحديثة دائماً تسعى للحاق بعجلة التقدم العلمي، فأوجدت نظريات ومفاهيم تتلاءم مع هذا التطور وكان لزاماًَ على المحاسبة- وخاصة محاسبة التكاليف والمحاسبة الادارية- تأطير هذه النظريات بما يخدم اهدافها.

ومن هنا جاءت مفاهيم هندسة القيمة وإعادة هندسة العمليات بوصفها احد ابرز الاساليب الادارية والتقنية الحديثة الملائمة لمواكبة التقدم العلمي والتغيرات في بيئة الاعمال لتحقيق الهدف الرئيس الذي تسعى اليه المؤسسات اليوم وهو تلبية متطلبات ورغبات الزبون من خلال تحقيق هدفي: تخفيض كلفة المنتج وتحسين قيمته لنيل رضاه، وهو المقياس الأساس لنجاح المؤسسات، ولذلك فإن هذا البحث يسعى الى بيان اهمية ودور الاسلوبين موضوعي البحث في تحقيق عوامل النجاح الأساسية للمنافسة حيث تعد هندسة القيمة اسلوباً مختلفاً في معالجتها للتكاليف المرتفعة للمنتج بتركيزها على تجزئة المنتج على وظائف ومكونات، ودراستها وتحليلها. اما أسلوب إعادة هندسة العمليات فركز على حاجة المنشآت الى تغيير عملياتها وانشطتها.

Design and Implementation of Single-Phase Boost PFC Converter
...Show More Authors

In this paper, a single-phase boost type ac-dc converter with power factor correction (PFC) technique is designed and implemented. A current mode control at a constant switching frequency is used as a control strategy for PFC converter. The PFC converter is a single-stage singleswitch boost converter that uses a current shaping technique to reshape the non-sinusoidal input current drawn by the bulky capacitor in the conventional rectifier. This technique should provide an input current with almost free-harmonics, comply with the IEC61000-3-2 limits, and a system operates with near unity power factor. The other function of the boost converter that should be
accomplished is to provide a regulated DC output voltage. The complete designed

Synthesis, Characterization, and Antimicrobial Evaluation of New Ceftriaxone Derivatives
...Show More Authors

The present study was designed to synthesize a number of new Ceftriaxone derivatives by its involvement with a series of different amines, through the chemical derivatization of its 2-aminothiazolyl- group into an amide with chloroacetyl chloride, which on further conjugation with these selected amines will produce compounds with pharmacological effects that may extend the antimicrobial activity of the parent compound depending on the nature of these moieties.

Ceftriaxone was first equipped with a spacer arm (linker) by the action of chloroacetyl chloride in aqueous medium and then further reacted with seven different aliphatic and aromatic amines which resulted in the production of the aimed final target products. The syntheses

The Development of the Suez Canal and Projects Competitors
...Show More Authors

The area around the Suez Canal has been chosen particularly  Sinai  to implement the new Suez Canal project parallel to the original 72-km-long channel due to the importance of the commercial site of the Arab Republic of Egypt, competing with shipping lanes, to accommodate the increasing maritime traffic  passing through the Suez canal, and to provide special services for trade world and reduce the economic cost of marine trip. The establishment of six tunnels for automobile and railway transport to Sinai The cost of the establishment of this new channel  and the establishment of the tunnels about (2.8) billion, of which 4 billion cost of the new channel. Project implementation period is one year. The new proj

Human recognition by utilizing voice recognition and visual recognition
...Show More Authors

Audio-visual detection and recognition system is thought to become the most promising methods for many applications includes surveillance, speech recognition, eavesdropping devices, intelligence operations, etc. In the recent field of human recognition, the majority of the research be- coming performed presently is focused on the reidentification of various body images taken by several cameras or its focuses on recognized audio-only. However, in some cases these traditional methods can- not be useful when used alone such as in indoor surveillance systems, that are installed close to the ceiling and capture images right from above in a downwards direction and in some cases people don't look straight the cameras or it cannot be added in some

Image Watermarking based on Huffman Coding and Laplace Sharpening
...Show More Authors

In this paper, an algorithm through which we can embed more data than the
regular methods under spatial domain is introduced. We compressed the secret data
using Huffman coding and then this compressed data is embedded using laplacian
sharpening method.
We used Laplace filters to determine the effective hiding places, then based on
threshold value we found the places with the highest values acquired from these filters
for embedding the watermark. In this work our aim is increasing the capacity of
information which is to be embedded by using Huffman code and at the same time
increasing the security of the algorithm by hiding data in the places that have highest
values of edges and less noticeable.
The perform

Heterocyclic compounds-based liquid crystals: Synthesis and mesomorphic properties
...Show More Authors

A series of liquid crystals comprising a heterocyclics dihydro pyrrole and 1,2,3-triazole rings [VII]-[X] were synthesized by many steps starting from a reaction of 3,3'-dimethyl-[1,1'-biphenyl]- 4,4'-diamine with chloroacetyl chloride in a mixture of solutions DMF and TEA to synthesise the compounds [I], then the compounds [I] reacted with malononitrile in 1,4-dioxane and TEA solutions to produce compounds [II], then the first step is repeated with compound [II] where it reacted with chloroacetyl chloride in mixture of DMF and TEA to give compound [III], this compound reacted with sodium azide in the presence of sodium chloride and DMF as solvent to produce the compound [IV], which reacted with acrylic acid by a 1.3 dipolar reaction in sol

The structure and optical properties of CdSe:Cu Thin Films
...Show More Authors

A polycrystalline CdSe thin films doped with (5wt%) of Cu was fabricated using vacuum evaporation technique in the substrate temperature range(Ts=RT-250)oC on glass substrates of the thickness(0.8?m). The structure of these films are determined by X-ray diffraction (XRD). The X-ray diffraction studies shows that the structure is polycrystalline with hexagonal structure, and there are strong peaks at the direction (200) at (Ts=RT-150) oC, while at higher substrate temperature(Ts=150-250) oC the structure is single crystal. The optical properties as a function of Ts were studied. The absorption, transmission, and reflection has been studied, The optical energy gap (Eg)increases with increase of substrate temperature from (1.65
