Utility-Based Anonymization Using Generalization Boundaries to Protect Sensitive Attributes

Journal of Information Security 2015年第3期6卷 179-196页

作者： Abou-el-ela Abdou hussien Nagy Ramadan Darwish Hesham A. Hefny Department of Computer Science Faculty of Science and Arts Shaqra University Shaqra KSA Department of Computer and Information Sciences Institute of Statistical Studies and Research Cairo University Cairo Egypt

Privacy preserving data mining (PPDM) has become more and more important because it allows sharing of privacy sensitive data for analytical purposes. A big number of privacy techniques were developed most of which used the k-anonymity property which have many shortcomings, so other privacy techniques were introduced (l-diversity, p-sensitive k-anonymity, (α, k)-anonymity, t-closeness, etc.). While they are different in their methods and quality of their results, they all focus first on masking the data, and then protecting the quality of the data. This paper is concerned with providing an enhanced privacy technique that combines some anonymity techniques to maintain both privacy and data utility by considering the sensitivity values of attributes in queries using sensitivity weights which determine taking in account utility-based anonymization and then only queries having sensitive attributes whose values exceed threshold are to be changed using generalization boundaries. The threshold value is calculated depending on the different weights assigned to individual attributes which take into account the utility of each attribute and those particular attributes whose total weights exceed the threshold values is changed using generalization boundaries and the other queries can be directly published. Experiment results using UT dallas anonymization toolbox on real data set adult database from the UC machine learning repository show that although the proposed technique preserves privacy, it also can maintain the utility of the publishing data.

Design Optimization for Generating a High Static Magnetic Field

引用

World Journal of Engineering and Technology 2023年第4期11卷 793-806页

作者： hussien A. Elharati Salma Ahmed Alharati Ziad Omar Wareg Mohamed Amro Waregh Department of Electrical Engineering Higher Institute of Science and Technology Tripoli Libya Physics Department Ministry of Education Tripoli Libya Higher Institute of Science and Technology Nalut Libya

This paper details the creation of a device capable of generating a powerful and consistent static magnetic field. This apparatus serves the purpose of quantifying the magnetostrictive strain found in materials like annealed cobalt ferrite and Terfenol-D, specifically those shaped as cylindrical rods. In our investigation, the use of static magnetic fields proves most advantageous. This choice is made to mitigate the generation of eddy currents, which would inevitably occur if the magnetic field intensity were varied. The fundamental idea behind this design involves employing a C-shaped iron core constructed from low-carbon mild steel. On this core, three coils are mounted, each capable of producing one-third of the required 9000 Oersted (Oe) magnetic field strength. The test specimen is situated within the “jaws” of the C-shaped core, thus completing the magnetic circuit. To manage the heat generated by each coil, a cooling system consisting of copper tubes is employed. These tubes facilitate the flow of air to dissipate the heat. To model and predict the magnetic field strength produced by the coils, finite element analysis (FEMM) software is utilized, and the results align closely with the anticipated outcomes. This design effectively generates a robust and unchanging magnetic field measuring a stable 9000 Oe in total. Consequently, this equipment finds utility in characterizing the magnetic properties of specific materials.

International Journal of Geosciences 2012年第3期3卷 549-564页

作者： Abed Salih Al Dulaymi Emad Abdul Rahman Al-Heety Bayan Muhie hussien Center of Desert Studies University of Anbar Ramadi Iraq Department of Applied Geology University of Anbar Ramadi Iraq

The geophysical study was performed east of Rutba town due to vertical electrical sounding in a net of forty points between Dhalaa and Dhabaa valleys. Geophysical electrical model applicated using Winsev6 program to determine the geo-electrical layers. Three geo-electrical layers were derived from geophysical survey. These layers are composed of four sediment types, such as clays, marls, marly carbonates, carbonates (dolomitic limestone), characterized by resistivity less than 20 ohm-m, 20 - 100 ohm-m, 100 - 350 ohm-m and more than 350 ohm-m, respectively. The thickness of the geo-electrical horizons are increased in Dhabaa Fault zone which characterized by multi karst shapes reflected as karst topography on the surface, which represents subsurface structural boundary for Mullusi aquifer, where this aquifer considered as main water supply for Rutba people in drinking water throughout 17 water wells located in Dhabaa site. Two empirical relation between Formation Factors (F) and Hydraulic Conductivity (K) obtained using linear and Polynomial regression techniques. The first equation of linear fit (F = 11.82 + 116.45 K;with a Correlation Coefficient of 0.94) represents the contribution between formation factor and hydraulic conductivity of a 2nd layer in Mullusi aquifer. The second equation of 3rd degree Polynomial Fit (F = 20.32 - 203.33 K + 1554.99 K2 -3127.30 K3;with a Correlation Coefficient of 0.75) represents the contribution between formation factor and hydraulic conductivity of a 3rd layer in Mullusi aquifer.

The main treatment strategy for glucose-6-phosphate dehydrogenase (G6PD) deficiency is averting the use of oxidative precipitants like drugs or foods that trigger haemolysis. However, subjects could experience acute crisis in a comorbidity state of diabetes, hypertension or infection. In addition, the condition could in turn predispose carriers to these chronic diseases. Aim of the study was to evaluate the frequency of haemolytic crisis in carriers with attendant chronic diseases, and also assess awareness and knowledge of aggravated reactions from these conditions. 282 subjects consented and participated in the study. A cross-sectional semi-structured interview questionnaire conducted from May to August 2013 was adopted. Questions focused on demographics, awareness and when disease was diagnosed, type and frequency of crisis, family history, screening and presence of other diseases and awareness of trigger from these conditions. A total of 69.9% were G6PD deficiency gene carriers and mostly fell within the age group of 31 - 40 (43.6%). 75.6% of the carriers were not aware that other disease conditions could exacerbate crisis. Non-drug related crisis was 85.3% compared with 14.7 drug related reactions. Out of the 69.9% carriers, 17.3% are diabetics, 18.3% of them are hypertensive and 25.9% are with bleeding disorders. Also, 29.1% had frequent episodes with bacterial infection. Symptoms experienced that were not drug related included, 44.8% attacks of pallor, 25.3% jaundice, 28.5% with shortness of breath, while 21.7% had dark urine frequently. No routine screening for other diseased conditions was carried out for these subjects despite experiencing frequent crisis that were not drug related. Carriers with other diseased conditions experienced more non-drug related crisis and were not aware of it.

International Journal of Geosciences 2013年第7期4卷 1055-1060页

作者： Omar H. Al Hattamleh hussien H. Al-Deeky Mohammad N. Akhtar Assistant Lecturer Hashemite University Zarqa Jordan Associate Professor Civil Engineering Department Fahad Bin Sultan University Tabuk KSA Lecturer Fahad Bin Sultan University Tabuk KSA

This paper presents experimental investigation for particles breakage for natural sand. The particle breakage was induced by subjecting the sample to one dimensional compression. Grain size analyses were performed before and after induced breakage. Thereafter, the sand shear strength parameters were assessed using direct shear box tests and the coefficient of permeability was assessed using constant head permeameter. Examining the obtained results revealed that the amount of breakage due to one dimensional compression was of order higher than the amount occurring during direct shear test. Peak shear strength parameters decreased with the particles breakage increasing. Moreover, dilation angle of shear strength pronouncedly decreases with the amount of particles breakage increasing. Crushing has obvious effect on the evaluated coefficient of permeability.

This study investigated the susceptibility pattern of different bacteria isolated from urinary tract infection to different antibiotics. 83 uropathogen bacteria were isolated from 300 urine samples taken from patients attended to Tikrit Teaching Hospital from March, 2011 through February, 2012. The patients were males and females aged between 4 days to 95 years. Bacteria obtained from urine samples were cultured and tested for antimicrobial susceptibility to 16 kinds of antibiotics. Urine samples were cultured on different media and incubated, thereafter bacteria were isolated and purified by streaking four times on the same media;isolates were identified depending on morphological, microscopic, and biochemical characteristics. The isolated strains of bacteria were tested for their susceptibility to some antibiotics using disk diffusion method. The antagonistic activity was evaluated by observing a clear zone of inhibition growth. The results showed that the bacterial species of Eschericia coli, Proteus mirabilis, Klebsiella pneumonia, Citrobacter diversus, Citrobacter freundii, Enterobacter aerogenes, Yersinia pestis, Pseudomonas aeruginosa, Klebsiella oxytoca and Hafnia alvei were identified in 44 (53%), 18 (21.7%), 4 (4.8%), 4 (4.8%), 3 (3.6%), 3 (3.6%), 3 (3.6%), 2 (2.4%), 1 (1.2%) and 1 (1.2%), respectively, of the isolates. The results of antimicrobial susceptibility test showed that 83 (100%) isolates were resistant to Ampicillin, Rifampicin and Erythromycin. 75 (90.3%) isolates were resistant to Cefotaxime, 67 (80.7%) isolates were resistant to Tobramyci. 66 (79.5%), 65 (78.3%), 56 (67.4%) and 48 (57.8%) isolates showed susceptibility to Nalidixic acid, Tetracycline, Nitrofurantoin, Chloramphenicol, respectively. 45 (54.2%) isolates were resistant to Azithromycin, Norfloxacin and Ciprofloxacin. Meropenem, Gentamicin, Amikacin, and Imipenem show significant effect on 35 (42.1%), 32 (38.5%), 27 (32.5%) and 1 (1.2%) isolates, respectively. In conclusion, signif
