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.

Improved undetected error probability model for JTEC and JTEC-SQED coding schemes
...Show More Authors

The undetected error probability is an important measure to assess the communication reliability provided by any error coding scheme. Two error coding schemes namely, Joint crosstalk avoidance and Triple Error Correction (JTEC) and JTEC with Simultaneous Quadruple Error Detection (JTEC-SQED), provide both crosstalk reduction and multi-bit error correction/detection features. The available undetected error probability model yields an upper bound value which does not give accurate estimation on the reliability provided. This paper presents an improved mathematical model to estimate the undetected error probability of these two joint coding schemes. According to the decoding algorithm the errors are classified into patterns and their decoding

This work concerned on nanocrystalline NiAl2O4 and ZnAl2O4 having spinel structure prepared by Sol–gel technique. The structural and characterization properties for the obtained samples were examined using different measurements such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), finally, Field emission scanning electron microscope (FESEM).The Spinel-type for two prepared compound (NiAl2O4) and (ZnAl2O4) at different calcination temperature examined by XRD. Williamson-Hall Methods used to estimate crystallite size, Average distribution crystallite size of two compound were, 34.2 nm for NiAl2O4 and32.6 for ZnAl2O4, the increase in crystallite size affecting by increasing in calcination temperature for both comp

ANTIANGIOGENIC ACTIVITY AND ROS-MEDIATED LUNG CANCER CELL LINE INJURY OF ZERUMBONE
...Show More Authors

Objective: Zerumbone (ZER) is a well-known natural compound that has been reported to have anti-cancer effect. Thus, this study investigated the ZER potential to inhibit Thymidine Phosphorylase (TP) and the ability to trigger Reactive oxygen species (ROS)-mediated cytotoxicity in non-small cell lung cancer, NCI-H460, cell line. Material and Method: The antiangiogenic activity for ZER was evaluated by using the thymidine phosphorylase inhibitory test. Reactive oxygen species (ROS) production was determined via DCFDA dye by using flow cytometry. Result and Discussion: ZER was found to be potent TP inhibitory with the IC50 value of 50.3± 0.31 μg/ml or 230±1.42 µM. NCI-H460 cells upon treatment with ZER produced sign

Synthesis and Characterization of Some New Benzodiazepinium Salt Derivatives under microwave Irradiation
...Show More Authors

An attempt to synthesize the benzoimidazol derivatives from the reaction of o-phenylenediamine and benzoic acid derivatives in the presence of ethanol and various ketones under microwave irradiation, 1 , 5 - benzodiazepinum salt derivatives were obtained instead of them. Unexpected reaction was happened for synthesis a new series of benzodiazepinium salt derivatives in a selective yield . The reaction mechanism was also discussed. The new compounds were purified and identified their structures were elucidated using various physical techniques like; FT- IR spectra, micro elemental analysis (C.H.N) and 1H NMR spectra.

HANDWRITTEN DIGITS CLASSIFICATION BASED ON DISCRETE WAVELET TRANSFORM AND SPIKE NEURAL NETWORK
...Show More Authors

In this paper, a handwritten digit classification system is proposed based on the Discrete Wavelet Transform and Spike Neural Network. The system consists of three stages. The first stage is for preprocessing the data and the second stage is for feature extraction, which is based on Discrete Wavelet Transform (DWT). The third stage is for classification and is based on a Spiking Neural Network (SNN). To evaluate the system, two standard databases are used: the MADBase database and the MNIST database. The proposed system achieved a high classification accuracy rate with 99.1% for the MADBase database and 99.9% for the MNIST database

Yield and quality of three potato cultivars under series of nitrogen rates
...Show More Authors

Undesirable growth of potato (Solanum tuberosum L.) crop under an excessive N fertilizer application is the main obstacle presently. This research was conducted to investigate the response of different potato cultivars; Russet Burbank, Shepody, and Superior, and its qualitative characteristics under a series of N rates. Six rates of N fertilization (0–280 kg ha−1) were applied on 11 sites in a randomized complete block design, with four replications. Sites with ≥30 g kg−1 of soil organic matter (OM) produced total tuber yield, marketable yield, and tuber weight per plant 39.5, 45.2, and 54.9%, respectively, higher than sites with ≤30 g kg−1 of OM. Tubers specific gravity increased by 0.18% in the sites with ≥30 g kg−1 of OM.
