About Faculty of Science

Faculty of Science

The Faculty of Science is the core at the University of Tripoli, as it was the first that established in this prestigious university. It is also the first faculty of science in Libya. At the present, it includes ten scientific departments: Departments of Zoology, Mathematics, Physics, Chemistry, Botany, Geology, Computer Science and Statistics, Atmospheric science and geophysics. It currently works to create a new department of Archaeology in order to study the scientific and research side of the historical heritage of the Libyan people. Graduates of this college have worked in various governmental sectors, such as oil exploration, extraction and refining, chemical industries complexes in Abu Kamash and Ras Al-Anuf, as well as plastics companies in production and manufacturing, and in factories for soap, cleaning materials and others. They were also recruited by the education sector in different research and pedagogical areas.

 

The graduates of this faculty have led the scientific process for many years and still represent the first building block in all colleges of science, and some other colleges in all Libyan universities for the past five decades. The scope of work for graduates included Faculties of Medicine (in the field of basic sciences, biochemistry, anatomy, histology and microbiology), many departments in the Faculty of Agriculture, general engineering, chemical and geological engineering; in particular, medical technology and pharmacy, and the Faculty of Economics and Arts. The Faculty of Science provides teaching assistants to other faculties and universities in the Libyan state.

 

The Faculty of Science is the first to create graduate studies programs in Libya, despite the nature of graduate studies in basic sciences, which need capabilities other than competent professors. Teaching staff in this institution graduated from international universities in the West and the East (USA, UK, Australia, and other European countries). They graduated from universities that are well-known for their high academic standard.

 

Having obtained their first university degree or higher degrees of specialization from Libya or abroad, graduates of Faculty of Science worked for industrial and nuclear research centers, petroleum sector, marine life, biotechnology, plastics, and other specialized research centers.

 

The Faculty has also enriched the scientific research movement in the fields of basic sciences in the Libyan state through the issuance of refereed basic science journal.

Contacts on polyester textile as a flexible substrate for solar cells

In the present work, the authors have studied conductive surfaces on polyester fabrics by using two types of commercially available conductive polymers; polyaniline and poly (3,4-ethylenedioxythiophene)-poly (styrenesulphonate) (PEDOT: PSS) with 100 nm aluminium thin film evaporated on top of the polymer so the fabric becomes a conductive substrate for inorganic thin film solar cells. Conductive polymer surfaces on woven polyester fabrics were obtained by knife-over-table coating technique. Surface resistivities for polyaniline and PEDOT: PSS coated fabrics were measured and found in the range of 400 × 103 and 1 × 103 Ω/□, respectively. Thermal stability tests were carried out to evaluate the effect of specific periods of heal treatment at different elevated temperatures on resistance of polymer coated conducting textiles. PEDOT: PSS exhibited better stability than panipol. According to long term tests, PEDOT: PSS coated samples showed improvement in conductivity over 3 days whereas panipol showed the opposite. Transmission Line Model tests were performed to measure aluminium/polymer contact resistances which were found to be 120 × 103 Ω for polyaniline and about 46.3 Ω for PEDOT: PSS. Mechanical bending tests for aluminium/PEDOT: PSS/fabric samples showed that the polymer can maintain the conductivity of samples by bridging micro-cracks in the metal film. arabic 10 English 59

Minimizing Fractional Errors in Floating Point Number

تدعم لغات البرمجة أعداد النقطة العائمة كنوع بيانات متضمن باللغة built-in data type. إلا أن تمثيل و دقة أعداد النقطة العائمة قد يختلف من لغة إلى أخرى ومن حاسوب إلى آخر. قسمة الأعداد الصحيحة قد تُنتج قيمة بالنقطة العائمة التي في كثير من الحالات يمكن أن تسكّن accommodated بالكامل في الحيز المخصص لها بذاكرة الحاسوب أو أنها تستمر بشكل لانهائي والذي قد ينتج عنه فقد في قيمة الناتج. إذا أخذ الناتج لتجرى عليه حسابات أخرى متتالية فتزيد فجوة الخطأ والتأثير قد لا يكون مقبولاً.في هذا البحث نقدم حلاً مستنداً على تمثيل أجزاء العدد الكسري (الجزء العشريmantissa ، الأساس base، الأس exponent) باستخدام أعداد صحيحة على شكل كسر اعتيادي. في هذه الحالة سنحصل على ثلاثة أعداد: العدد الصحيح Integer value والبسط Numerator والمقام Denominator. مع توضيح طرق إجراء العمليات الحسابية على ضوء هذا التمثيل.كنتيجة لهذا البحث ستكون هذه الطريقة في تمثيل الأعداد الكسرية تمثيلاً كاملاً دون فقدان لشكل الكسر أو جزءًا من قيمته، وتقليل الخطأ التراكمي الناتج عن تتالي العمليات الحسابية. وقد تم إعداد بعض الأمثلة البرمجية للتحقق من فعالية هذه الطريقة ومقارنة نتائجها مع نتائج التمثيل العشري المتبع للنقطة العائمة. Abstract Programming languages support floating point numbers as a built-in data type. However the representation of floating point numbers differs from one language to another.Integer division may result in floating point value that in many cases can be fully accommodated in computer memory or it goes infinitely which produces a lost in the output value. If the result is then taken for further calculations the gape of the error increases and the effect may not be acceptable.In this research a solution is proposal based on representing fractional numbers (mantissa, base and exponent) using integer numbers format. In this case we get three parts: the Integer value, the Numerator value and the Denominator value. The operations on such representation are also introduced. This representation is evaluated and compared with the traditional (Mantissa) representation. Sample programs using C++ language are developed showing how this representation can be used and how fractional numbers are declared and used, with comparison with the normal representation.

Abstract In this thesis, we study the solution of Laplace's equation in some curvilinear coordinates systems with some applications. We will concentrate first on curvilinear coordinates and find scale factor which is important in writing the Laplace's equation for any curvilinear coordinate system. And we presented the (cylindrical, spherical) coordinates system and the solution of Laplace's equation in these coordinates, as well as Dirichlet application with closed domain (cylinder, sphere). Finally, solutions of Laplace's equation in toroidal coordinates system were studied in details, also we studied the bipolar coordinates system, and its relation with toroidal coordinates, as well as Dirichlet problem for a domain bounded by a toroidal surface
