Optimizing Network Resilience with Segment Routing A Comparative Study of SR TI-LFA and rLFA
Conference paper

Abstract: Network operators are confronted with the demanding requirements resulting from the evolution of IP networks. As a result, it has become necessary to provide rigorous Service Level Agreements (SLAs) that are in line with these requirements. However, traditional IP networks lack the necessary flexibility, scalability, and manageability to meet these demands. In order to address these limitations, the segment routing (SR) architecture has been developed. SR is based on source-routing and tunneling paradigms, which enable IP/MPLS and IPV6 networks to operate in a simplified and more scalable manner. The focus of this paper is on network protection (resiliency) using Topology Independent Loop-Free Alternatives Fast Re-Route (TI-LFA FRR) using MPLS as the underlying technology. SR overcomes the limitations of previous network protection mechanisms in terms of coverage and optimal path selection. To show the effectiveness of SR TI-LFA in comparison to its predecessor, Remote Loop-Free Alternate (rLFA), we have implemented various scenarios. These scenarios are designed to highlight the superior capabilities of TI-LFA.

Increasing Oil Recovery by Gas Injection for Libyan Carbonate Sedimentary Field (LCSF) by using Eclipse Software
Journal Article

In this study, two software MBAL - Petroleum Experts and Eclipse are used to do comprehensive reservoir study for LCSF plane of development, this study covered analyses and evaluation. Gas injection essentially increases the rate of oil field development and in many cases permits increased oil recovery. This paper demonstrates a successful simulation case study based on a field data of a project. The objective of this study is to improve recovery from Libyan Carbonate Sedimentary Field by three wells of gas injection. To do that, first, the simulation 3-D model was built by using advanced reservoir simulation software (Schlumberger Eclipse). Second, select the best zone for gas injection. Third, select the best location for injector well. Fourth, determine the injector well depth. The results of the paper can be seen to match the real data of the reservoir with the results of the program using a MBAL software. The simulator results show the reservoir pressure history curve is matching to the stimulation curve, this gives a good allusion of the input data that has been entered to the model. The driving mechanism of this reservoirs it comes from three natural forces, which are fluid expansion, PV compressibility, and water influx. Gas injection scenario has a good plateau bpd lasts approximately 3 years and after that started to decrease. The Cumulative oil production is 108442340 STB barrels of oil with the recovery factor approximately 0.52805 and final reservoir pressure is maintained 328.76 pisa

الأزمة الليبية في ضوء جهود البعثة الأممية : من طارق متري إلى عبدالله باتيلي، هل من مقاربة واقعية تجمع الفرقاء؟
مقال في مجلة علمية

  إثر ثورة 17 شباط/فبراير 2011، التي عصفت بنظام القذافي، دخلت البلاد في متاهة صراع مرير تعددت أدواته وأطرافه، مما ترتب عنه شرخ عميق أصاب المجتمع الليبي. وجدت ليبيا نفسها في فك التدخلات الخارجية الضارة، مما جعل من البلد ساحة صراع وتنافس لقوى دولية وإقليمية تخلق الأزمات وتساهم في زعزعة استقرار وأمن المنطقة برمتها. 

برغم الجهود التي بذلتها الأمم المتحدة في ليبيا، لم تفلح في تجاوز المعضلات التي تمثل جوهر الأزمة القائمة، ولم تنجح إلا في تقديم تصورات وخرائط طريق لتقاسم السلطة. كما لم تفلح تلك الترتيبات إلا في زيادة عدد المكونات أو عناصر الأزمة السياسية. وهو ما أثار الشكوك حول كفاءة وفاعلية البعثة الأممية ومقاربتها للحل في ليبيا، وفي الوقت نفسه، ثار الجدل حول جدوى تلك الجهود، وما إذا كانت فعلاً تحمل في جعبتها أفكاراً بنّاءة تفضي إلى فك رموز الأزمة الليبية وحلحلة كل تعقيداتها، بما يحقق الاستقرار والأمن وعودة الدولة موحدة بمؤسساتها.

الكلمات المفتاحية: الأزمة الليبية، المقاربة الأممية، التسوية السياسية، التدخل الخارجي، الولايات المتحدة الأمريكية
