Applying Arabic Stemming Using Query Expansion

The process of conflating different Arabic word formats to their stem or root is called stemming. Indexing text collection using stems or roots has been reported to be superior to using original word formats. However, the Arabic text stemming has negative effects on words. It conflates words with different meaning under one index term. This occurs frequently in Arabic when using stems and it becomes more frequent when choosing roots to index the collection. Furthermore, search engine whose index is constructed using a particular stemmer makes it a stemmer-dependent engine. In this paper, we show how we can still use stemming to reach the same results without indexing the stemmed text. Original words have been indexed, and a stemmer used to extract word variants and add them to the user query. Apart from making our search operation stemmer-independent, we proof that our approach is as good as light stemming and is significantly better than root stemming. arabic 5 English 41

مجموعات الإختبار العربية ودورها في تطوير أداء محركات البحث العربية

يعتمد تطور البحث العلمي عادة على القياس. فبدون قياس لا يمكن معرفة مدى كفاءة أي نظام أو أداة مستحدثة. في هذه الورقة نعرض أدوات القياس التي يتم إستخدامها في تحديد كفاءة أنظمة إسترجاع المعلومات عموما و نركز على ما هو متوفر منها لقياس أنظمة إسترجاع النصوص العربية، ونبين مدى التطور التي أحدثه على مستوى إسترجاع النصوص العربية. تركز الورقة على عرض مجموعات الإختبار العربية المتوفرة حاليا, وتبرز القصور التي تعاني منه، وتظهر الحاجة الى وجود نجموعات اختبار عربية تتوافق مع واقع النصوص العربية الموجودة حاليا على شبكة المعلومات الدولية. كما نقوم بعرض مجموعة الإختبار التي قمنا بإعدادها لإختبار ظاهرة زيادة حجم النصوص العربية. ونبين أن زيادة الحجم في النصوص العربية يؤثر سلبا في مستوى آداء أنظمة الإسترجاع العربية. arabic 125 English 0

Survey on Academic Staff Awareness of Open Educational Resources

Open Educational Resources become an important asset for many educational institutions. In this paper we report the analysis of our survey data on using open educational resources at the University of Tripoli (UoT) among the academic staff members. The survey data was collected electronically to assess the awareness and usage of open educational resources within the University of Tripoli. Results of our survey reveal that 90% of academic staff members surveyed are using open educational resources, but they are not contributing much to OER due to lack of support from university. arabic 8 English 56

Study and test performance of the Zigbee Wireless technology in some network models by using Opnet software

ZigBee Wireless Technology is the leading global standard for implementing low-cost, Low-data-rate, short-range wireless networks with extended battery life. The ZigBee standard provides network, security, and application support services operating on top of the IEEE 802.15.4 Medium Access Control (MAC) and Physical Layer (PHY) wireless standard. It employs a suite of technologies to enable scalable, self-organizing, and self-healing networks that can manage various data traffic patterns, The low cost allows the technology to be widely deployed in wireless control and monitoring applications, the low power-usage allows longer life with smaller batteries, and the mesh networking provides high reliability and larger range. ZigBee has been developed to meet the growing demand for capable wireless networking between numerous low power devices. In this paper , we will try to give a complete picture about ZigBee technology including the structure of this technology, the layers where this technology works referred to the OSI model, how this technology works, the main components that use to create a ZigBee network, The objective of this simulation is to establish tree topology networkby; using an OPNET Modeller 14.5 program, and to investigate the performance of the network model, and see the effect on data when we change the time of transmission and finally we will investigate the performance of some network models that employ IEEE 802.15.4 protocol using different scenarios. arabic 19 English 91

Implementation Network Management Solution Using PRTG and Solar Winds Tools

Successful companies know that network management is crucial for the proper support and maintenance of network infrastructure. When it comes to managing a large-scale or highly complex network, you’ll need a powerful network management system that will meet your challenging business needs. There are several programs suggested different types of solutions. PRTG and SolarWinds are an excellent solution, since they have many features that help the network engineer, administrator or technician to easily control, manage and monitor the devices comprehensively. Moreover, PRTG and SolarWinds can integrate with monitoring and management protocols such as SNMP and NetFlow to provide an excellent integrated unified management solution. That being said, PRTG and SolarWinds will facilitate the management of network devices throughout performing configuration, Security, Fault, Performance and Accounting management which will increase productivity, Quality, Revenue and lower the cost. arabic 9 English 66

Antimicrobial Sensitivity Patterns of Pseudomonas aeruginosa Isolates Obtained From Foot Ulcer Diabetes Patients in Tripoli, Libya.

Background: Pseudomonas aeruginosa is one of the most invasive organism that causes severe tissue damage in diabetic foot ulcers. A major problem in P. aeruginosa infection because of that it is commonly exhibits a high degree of resistance to antimicrobial agents .To improve appropriate antimicrobial therapy and reduce the incidence of antibiotics resistant bacteria, information on the antibiotic susceptibility to this bacterium is urgently needed. Therefore, the aim of this study was to isolate and determinate the antimicrobial susceptibility of the P. aeruginosa in diabetic foot ulcers patients. Methods: This study was carried out over the period between June 2014 to April 2015 at Tripoli Medical Center. A total of 120 bacterial isolates were cultured onto bacteriological media such as nutrient agar, MacConkey agar and blood agar. Identification of retrieved bacterial isolates was done using standard diagnostic microbiological laboratory methods and antibiogram was determined by VITEK ® 2 compact automated system. Results: Twenty one strains of P. aeruginosa from 120 diabetic foot ulcers were detected. P. aeruginosa isolates exhibited multidrug resistance to Ampicillin, Augmenting, Cefuroxime, Cefoxitin, Cefazolin, Ceftriaxone, Trimethoprim/sulfamethzole, Piperacillin. However, all isolates of P. aeruginosa were 100 % sensitive to Imipenem. Conclusion: P. aeruginosa infections of diabetic foot ulcers patients have multi-drug resistant. Imipenem is the empirical antibiotic of the choice. Key words: Pseudomonas aeruginosa, diabetic foot ulcer, antibiotics resistance arabic 17 English 114

Salmonella Enteritidis’ Proteins produce in Vitro and in Vivo Protection against Colonization

Salmonella enterica can be considered as one of the most important causes of foodpoisoning with poultry thought to be the main source. Although S. Typhimurium, S. Enteritidis and the vast majority of other Salmonella serovars generally produce little systemic disease in adult chickens, they are able to colonize the alimentary tract of poultry. The two caeca are the main sites of the colonization of Salmonellae in chickens, and the bacteria can be easily harvested from the caeca for analysis. Bacterial proteins analysed utilizing SDS-PAGE showed differences between in vitro and in vivo that out of about 40 protein bands of in vitro preparation only a few (3-5) bands can be visualized from in vivo preparations. We suggested that some avian proteases might be responsible. Accordingly, and to investigate the hypothesis that bacterial-precipitated protein harvested from chickens is thought to be more protective than bacteria grown in broth culture, the immunogenicity of protein-precipitated vaccines harvested from chicken intestine and those from broth culture (in vitro), were compared using bacterial proteins as an orally inoculated vaccine candidate in chicken. The results demonstrated that the in vitro sonicated proteins obtained from a nutrient broth culture had a much better protective vaccine effect than the in vivo sonicated proteins preparations harvested from bacteria grown in chickens arabic 14 English 81
