    ( 2006-2013) الاحتياجات الأمنية الإسرائيلية في الضفة الغربية بعد حرب العام 2006
    (AL-Quds University, 2015-05-20) احمد محمود محمد شديد ; Ahmad Mahmoud Mohammad Shadid ; عماد البشتاوي ; أحمد فارس عودة ; محمد المصري
    The West Bank is one of the issues that form the core of the Arab-Israeli conflict. This conflict has to do with Israel’s control of the land for both exploiting its resources and for allegedly security reasons. The study sheds light on the Israeli security strategy that aims at holding on to both land and air of the West Bank. This study aims at examining the Israeli stance vis-à-vis the final solution resulting from negotiations with Palestinians about the status of the Palestinian territories in the West Bank. Moreover, the study aims at monitoring the Israeli security trends in the light of the studies published by Israeli research centers and of the official security positions that are conveyed by the Israeli security and military establishments to the political circles. However, this will help us better understand the Israeli security-related perceptions and proposals that will be drafted in any future negotiations especially those pertaining to the final status . The problem of the study seeks defining the real Israeli intentions regarding the West Bank as the Israeli security and military establishments view it as their strategic depth. After the 2006 war, Israel started to focus on many security issues that Israel perceives highly necessary for protecting her land and population, a policy that will impede reaching a final and just peace agreement based on international legitimacy represented mainly by resolution 242 that stipulates a full Israeli withdrawal from the territories occupied in 1967. The study concludes that the Israeli security establishment has the final word regarding negotiations with Palestinians and that withdrawal from the West Bank is unlikely in the foreseeable future for it will, according to the Israelis, jeopardize their security given their economic benefits they may gain should they keep their occupation of the West Bank.

    New computer network topology, called Penta-S, is simulated. This network is built of cross bar switch modules. Each module connects 32 computer nodes. Each node has two ports, one connects the node to the crossbar switch module and the other connects the node to a correspondent client node in another module through a shuffle link. The performance of this network is simulated under various network sizes, packet lengths and loads. The results are compared with those obtained from Macramé project for Clos multistage interconnection network and 2D-Grid network. The throughput of Penta-S falls between the throughput of Clos and the throughput of 2D-Grid networks. The maximum throughput of Penta-S was obtained at packet length of 128 bytes. Also the throughput grows linearly with the network size. On the opposite of Clos and 2D-Grid networks, the per-node throughput of Penta-S improves as the network size grows. The per-packet latency proved to be better than that of Clos network for large packet lengths and high loads. Also the packet latency proved to be nearly constant against various loads. The cost-efficiency of Penta-S proved to be better than those of 2D-Grid and Clos networks for large number of nodes (>200 nodes in the case of 2D-Grid and >350 nodes in the case of Clos).On the opposite of other networks, the cost-efficiency of Penta-S grows as its size grows. So this topology suits large networks and high traffic loads.

    One of the major obstacles facing the field of structural biology in the postgenomic era is the inherent difficulty of solving the structure of membrane proteins under native conditions. Membrane proteins share a common property; part of their structure is embedded in the lipid bilayer. This feature makes them attractive drug targets, which requires a detailed knowledge of the secondary structure of their transmembrane domain. Both crystallography and NMR still encounter difficulties in handling membrane proteins, so there is an urgent need for new biophysical methods and new insights in the biophysics of membrane proteins to solve the secondary structure of such proteins. The outbreak of the severe acute respiratory syndrome (SARS) virus, July 2003, has presented a formidable challenge for the scientific community. As part of that effort, we decided to study the high resolution backbone structure of E transmembrane proteins of the SARS coronavirus, by Attenuated Total Internal Reflection (ATR) FTIR of eighteen of isotopically labeled sites with ( 13C=18O) of the synthesized sequence for the SARS coronavirus E protein transmembrane domain. ATR-FTIR spectroscopy is a wellestablished method for generating precise structural information on isotopically labeled membrane proteins embedded in a lipid bilayer. We used the new biophysical method site specific infrared dichroism (SSID), to investigate the structure and orientation of transmembrane. α-helical bundles We postulate in this work that the E protein of SARS CoV is α-helix, and it has 26 residues embedded in the lipid bilayer, and the SARS CoV E protein is not a regular helix, but it adopts a unique transmembrane helical hairpin model, and the E protein has two possible kinks at residue No. 26 and 31 Phe and Leu respectively within the lipid bilayer, which isreported for the first time in this thesis. And it also has a possible kink in residue No 15 too. All the results were confirmed experimentally.

    Comparative study on feature selection and ensemble methods for sentiment analysis classification
    (AL-quds University, 2020-06-10) Zahir Mohammad Adnan Younis ; زاهر "محمد عدنان" يونس
    People use the Web and social media to express their opinions and comments on various topics and posts generating huge amounts of data. Hence, comes the necessity to analyze this large amount of text regarding a certain subject and figuring out what people think of it. The interest and necessity of this analysis is continuously rising in many fields, such as politics, marketing, entertainment, sports, etc., to figure out people opinions, thinking, interests, preferences, and trends. Consequently, analysis, classification and clustering of this huge amount of text data regarding certain subjects became an interest of a vast number of researchers and beneficiaries. This analysis of text data content is known as sentiment analysis. Sentiment Analysis (SA) is a text-mining field that computationally treats and analyses these sentiments (opinions, thinks, subjectivity, interests, preferences, etc.,.) of available text. SA aims to classify expressions in a text as positive, negative or neutral opinion towards the subject of interest. The main objective of this research is to carry out a comparative study on the accuracy and performance of feature selection and ensemble methods for SA classification. The comparison was carried out using different combinations of classification algorithms for classifying text to being either positive or negative. During the comparison of the algorithms and methods, the results showed that better accuracy can be achieved based on the used feature selection method (i.e., statistical, wrapper, or embedded). Additionally, it showed which feature selection method outperforms and is more suitable than other methods for the type of data and classification algorithms. Furthermore, when using combined ensemble methods (Bagging, Boosting, Stacking and Vote) performed better than using a single classifier by means of accuracy. Moreover, merging feature subsets selected by embedded method improved classification accuracy. Finally, tuning the parameters of feature selection methods improved the classification accuracy and reduced the time needed to select feature subsets. Particularly, the results showed that accuracy depends on the feature selection method, ensemble methods, number of selected features, type of classifier, and tuning parameters of the algorithms used. A high accuracy of up to 99.85% was achieved by merging features of two embedded methods when using stacking ensemble method. Also, a high accuracy of 99.5% was achieved by tuning parameters in stacking method, and it reached 99.95% and iv 100% by tuning parameters in SVMAttributeEval method using statistical and machine learning approaches, respectively. Furthermore, tuning algorithms' parameters reduced the time needed to select feature subsets.

    (AL-Quds University, 2007-06-10) كفايه جمعه حامد حامد ; KEFAYA JUMA HAMED HAMED ; غسان بعلوشة ; Dr. Lina El-Khairy ; Dr.Hisham Darweesh
    Pediatric asthma is a serious illness that poses tremendous stress on patients and their families alike. Unfortunately the disease's incidence is on a rise worldwide. Pediatric asthma is a chronic disease affecting the small bronchi leading to inflammation with subsequent edema and hypersecretion resulting in narrowing of the lumen demonstrated in cough, dyspnea and wheezes. Pollution, cigarette smoke, dust mite, domestic animal and extreme weather conditions are considered causative and triggering factors. Genetic factors play critical role in respiratory hypersensitivity also identified to be an important risk factor in pediatric asthma. Children are primary victims, being exposed, early on in life, to thousands of attacks of acute severe asthma and requiring hospital referral. The study aims was to identify the most prevalent environmental - genetic risk factors that affect pediatric asthma in east Jerusalem/ Palestine. The sample size consists of 300 children from East Jerusalem between 5 and 16 years old. One hundred patients represent bronchial asthma ,case and 200 with other diseases. The purposive sample is taken from four medical centers in East Jerusalem and two major medical institution ,Al- Makassed Islamic Charitable Hospital and Augusta Victoria Hospital (AVH). The study was approved by the scientific research committee at Al –Quds University, and a permission to conduct the study from the administration of Al- Makassed Islamic Charitable center, the Arab medical health center, the American medical center and from the Palestinian ministry of health center also along with permission from AVH and Makassed Islamic Charitable Hospital was obtained The Alpha 1 Antitrypsin genotype was perform for 50% of the samples (50 case, 100 control) in addition 300 questionnaire was distributed for 300 families of children selected in the study area . Pearson chi square was used to check the association of environmental risk factors that affect pediatric asthma in east Jerusalem Palestine. Result of the study demonstrate that there is a strong association between pediatric asthma and the presence of domestic animal in home , second hand smoking, and family history of asthma is strongly related to asthma .on the other hand genetic risk factor is poorly associated with asthma among children in east Jerusalem /Palestine.
