Item 1 Superglobals Sanitization against SQL injection and XSS(جامعة النيلين - كلية الدراسات العليا, 2016) Osman Elnour Sulieman; Mohammed Hassan Ahmed; Prof. Elsamani A. talab; Prof. Awad Alkarim Mohammed YousifSQL injection attack, exploit the problem of insufficient input data validation to trick PHP applications into executing unintended queries that allow hackers to bypass login screen, read, update, alter, create, or even delete sensitive data stored in the backend database. Cross site Scripting-XSS, harness the same problem to access sensitive page contents, session cookies, and a variety of other information retained by the browser on behalf of the user. This problem can be solved by performing static source code analysis to detect taintable points in the code before the application is deployed on the web. In this paper, we present a novel technique depend on reading your PHP source code file line by line and uses regular expressions to precisely find superglobals that hold form parameters, request details, cookies and session information and automatically add a user-defined function named as sanitizer to the source code. The Sanitizer will receive superglobals values to sanitize them against SQL injection and XSS. We implemented our approach in a simple tool called SQL Injection-XSS sanitizer. Our results show that the tool is capable of protecting PHP applications against untrusted input data with high rate.Item 2015– أثر التمويل المصرفي في عجز الموازنة في السودان للفترة 1991(جامعة النيلين - مجلة الدراسات العليا, 2018-04-15) الدكتور/ وراق علي وراق ناصرتهدف الدراسة إلى بيان أثر التمويل المصرفي في عجز الموازنة في السودان خلال .)6062 – الفترة ) 6992 تم استخدام الأساليب الإحصائية التي تتعامل مع طبيعة وخصائص السلاسل الزمنية لتحديد العلاقة بين متغيرات الدراسة مثل اختبار جذر الوحدة، التكامل المشترك، النموذج المقدر، في المديين الطويل والقصير. ومن خلال إنحدار التكامل المشترك اتضح أن سعر الصرف ) EX ( ومعدل التضخم ( INF ( أكثر تأثيراً في المدى الطويل نتيجة لزيادة الإنفاق بعد اتفاقية السلام في العام 6002 م وقلة الإيرادات نتيجة لقلة الإنتاج والإنتاجية وخروج عائدات النفط من الموازنة العامة مما زاد من عجز الموازنة. أما نتائج النموذج المقدر أظهرت أن الناتج المحلي الإجمالي (GDP) أكثر تأثيراً في المدى القصير نتيجة للإصلاحات الهيكلية. لذلك يوصى الباحث بالاهتمام بزيادة معدلات الناتج المحلي الإجمالي من خلال إصلاحات هيكلية تستهدف زيادة الإنتاجية وتشجيع المنتجين لتحقيق الاستقرار الاقتصادي.Item Academic Dissertations Electronic Archiving and Scientific Plagiarism(جامعة النيلين-كلية الدراسات العليا, 2016-04-01) Hala S.MahgoubThis paper aim to illustrate the relation between academic dissertation electronic archiving and scientific plagiarism.

Abstract: System identification techniques are routinely used in experimental stability and control studies throughout the aerospace industry. It composes a mathematical model, or series of models, from measurements of inputs and outputs of dynamic systems. The estimated models allow the characterization of the response of the overall aircraft or component subsystem behavior. This paper discusses the use of System Identification Toolbox of MATLAB/SIMULINK for the estimation of aircraft flight dynamics in longitudinal channel. The data extraction, model selection and estimation of aircraft dynamics by process modeling along with data validation, time and frequency response analysis is illustrated using the system-identification simulation environment.Item AKSCTS: A Smart Car Tracking System Using GPS and GSM with PIC 16F887 Microcontroller(Graduate College - Alneelain university, 2018-01-01) Ahmed Mohammed Elhadi, Eltaher Mohamed Husseinلا يخفى على الجميع التطور المهول في عالم التكنلوجيا وازدياد الحوجه لها يوما بعد يوم في جميع المجالات بما في ذلك أنظة الحماية بكل تأكيد. من أبرز أنظمة الحمايه هو ما يعرف بالأنظمة الذكية لتتبع المركبات. هذا النوع من الأنظمة يساعد الناس كثيرا في حالة ما اذا تم سرقة مركباتهم او اذا ما ضلو الطريق. النظام المفترح في هذه الورقة هو نظام ذكي للتبع المركبات يمكن دمجه في أي مركبة لتحديد موقع هذه المركبة وتحديث هذا الموقع بين الفينة والاخرى. يتكون هذا النظام من متحكمة دقيقة وووحدة لتحديد المواقع ووحده جي اس ام للربط مع شبكة الهواتف المحمولة. تم التحقق من نتائج هذا النظام عن طريق موقع الكتروني موثوق لتحديد الموافع للتأكد من مدى دقته وفعاليه ولاثبات مدى فعالية المفهوم بصورة عامة.

All products must be safe, clinically effective and of appropriate and consistent quality. Every blood transfusion service should develop an effective quality system covering all aspects of activities and ensure traceability, from the recruitment and selection of blood donors to the transfusion of blood and blood products to patients. Objective: This study aimed to assess quality system adoption levels in blood transfusion services in Sudan.Item Assessment of Spatial constraints for the allocation of Fuel stations in ABHAUsing GIS Techniques(Graduate College, 2017-11-01) Mohammed AlghobiriThe main objective of this study is to find out the extent to which Fuel stations allocations in the city of ABHA are adhering to spatial constraints issued by the Ministry of Municipals and Rural Affairs (MMRA). GIS technologies were used to achieve the study purposes. The study used some spatial analysis tools available in Applied package open source QGIS 2.12 to identify the distribution patternsof fuel stations(37 stations) in the study area.It also measures the distances between them and some other sites included in the list, such as schools, hospitals, shops, gas kitchens and restaurants by means of Distance matrix, buffering and Nearest neighbor. The study shows that there were good commitments by local authorities in following the official instructions regarding fuel stations allocations. However, the study identified some sites that had failed to live up to the expected level of guidelines fulfilling.A number of recommendations were presented for decision makers to improve their spatial decisions and to avoid potential hazardous of such activities.Item Assessment of the Impacts of Finance on the Rainfed Agricultural Sector Function, in Gedarif State (1992-2013(جامعة النيلين, 2014) Ali Ibrahim Musa AltaibThis study was conducted in rainfed agriculture sector finance in Gedarif state during period of (1992-2013). The main objective of the study is to generate assessments for rainfed agriculture sector financing function, to evaluate the financing policy, and to determine the optimal useful financing method. The study depended mainly on secondary data which were collected from the Central Bank of Sudan – Gedarif Branch, ministry of agriculture, and the Central Bureau of Statistic. Regression analysis technique was used so as to attain the stated objectives. The results of the selected multiple regression model revealed that one unit increase in capital cost, Consumer Price Index, and Production will increase the Financing volume by (3.92), (691.1), and (13.499) respectively, it was also found to be highly significant with positive signs. This indicates the importance of crops’ prices trends, rates of financing institutions’ profitability, and production size change in the financing volume determination.
