A comparison of Pattern Recognition Approaches for Recognizing Handwriting in Arabic Letters
Conference paperFor Arabic letters recognition, we achieve three of pattern recognition approaches namely gray level co-occurrence matrix (GLCM), local binary pattern recognition (LBP) and artificial neural network (ANN) and compare between them to result best performance. Two of these methods level co-occurrence matrix and local binary pattern recognition are used for feature extraction whereas in artificial neural network (ANN) we use the intensity values of pixels for input of the neural network. Two classifiers are used, the K-Nearest Neighbor classifier (KNN) for the LBP, GLCM and neural network classifier for (ANN) artificial neural network. Also, we evaluate the results by using leave one person out approach, fold classification and leave one out.

Modelling Future Temperatures Change in Libya Linking to the Planning of Sustainable Development
Conference paperABSTRACT
In the 21st century, climate change is considered one of the greatest environmental threats to the world, and it has greater negative impacts on human society and the natural environment. All the IPCC's reports concluded that we should prepare scenarios and strategies for under the conditions of forthcoming global change. This study presents the projections of future changes under HadCM3 A2a and HadCM3 B2a SRES scenarios using the statistical downscaling model (SDSM) in the period (2020-2099) and their link to the planning of sustainable development in Libya. Results of downscaling show that the SDSM model can be well acceptable regard its performance. The result of the SDSM model showed great reliability of SDSM in ascertaining changes for the periods; (2020-2039), (2040-2059), (2060-2079) and (2080-2099), relative to 1961–1990. Trend analysis in Libya showed an increase in average annual and monthly temperature, compared to the baseline period for both HadCM3A2a and HadCM3B2a scenarios in both the dry and wet seasons. Thus, there is likely to be a significant warming in local surface temperature, which is enough for a significant change on the energy balance and is likely to affect water availability. The SDSM is well to help decision-makers understand the expectations of the change in extreme temperatures in the future and its environmental and economic impacts and social in Libya.

Traffic Movement at Five Intersections on Jamal Abdul-Nasser Street - Sebha
Journal ArticleJamal Abdul-Nasser is a major trunk road that divides Sebha city into two semi-equal parts. It connects almost all districts with different activities and services in the center of the city. Alongside Jamal Abdul-Nasser Street, exist various types of activities: administrative, educational, commercial, public services and some other activities. Due to its importance, the street carries out the densest traffic movement within the city. This paper tries to study and analyze traffic movement at five intersections on Jamal Abdul-Nasser Street: (1) Al-Nahdha; (2) Khaled IbnAl-Walid; (3) Al-Khotoot; (4) Al-Tijari Bank; (5) Al-Zeraie Bank. Selection of the pre-mentioned intersections referred to their importance as converging points to various important activities and land uses. Data required for the study purposes include intersection characteristics, traffic flow characteristics and traffic composition pattern. The results reveal the significance of taking care of the geometric and regulatory aspects that enable the intersections to perform well with regard the smoothness of traffic flow.

SWOT analysis applications: An integrative literature review
Journal ArticleA strengths, weaknesses, opportunities, and threats (SWOT) analysis has become a key tool used
by businesses for strategic planning. Scholars have conducted SWOT research for over six
decades. However, a collective understanding of SWOT analysis remains vague. This study
accessed, analyzed, and synthesized the SWOT literature, allowing for new theoretical
perspectives and frameworks to emerge. Using an integrative literature review, this study reviewed
SWOT studies historically, providing a greater understanding of the SWOT analysis in different
sectors and the different approaches used in SWOT studies. Furthermore, it fills the knowledge
gap in the strategic planning context and indicates meaningful implications for managers that could
help improve their strategic decisions.

Mechanization the traditional admission systems and their role in improving the quality of inputs for higher education institutions
مقال في مجلة علميةThis study aims to build a model for a unified electronic admission system for Libyan higher education institutions. It has been noticeable that tertiary institutions in Libya have poor outcomes, and perhaps one of the reasons for that is the presence of defects in the current admission systems and their policies, which leads to selecting and accepting inappropriate applicants. The admission systems in most Libyan higher education institutions are outdated and still based on paper applications.Hence, this research was conducted to look at the Arab experiences in employing technology to develop admission systems at higher educational institutions. The research was also conducted to determine whether those Arab experiences can be applied to our local tertiary institutions, and see if they can they improve the quality of higher education outcomes. The researchers critically reviewed a number of tertiary admission systems and procedures offered at some educational institutions in Arab countries to reach an appropriate proposal for an online admission system to use at higher education institutions in Libya. The target admission system aims to offer many advantages and benefits such as saving time and effort for students and workers, as well as speeding up the processes of admission applications and checking application statuses.

Lithostratigraphy of the upper Lower Devonian through the upper Middle Devonian succession of the southeast Darling Basin, western New South Wales, southeastern Australia: a case study of sedimentological features and significance of depositional facies
Journal ArticleDetailed sedimentological analysis of depositional facies through lithostratigraphic correlation was conducted for the upper
Lower Devonian through the upper Middle Devonian Snake Cave Interval strata of the southeast Darling Basin. The methodology
used includes identifying changes in rock types from sedimentary lithotypes within different facies associations from well
data, wireline-log patterns and palaeoenvironmental reconstruction. This has helped to define a lithostratigraphic correlation for
the Snake Cave Interval section. This study has re-interpreted the upper and lower boundaries of the Snake Cave Interval using
marked changes in gamma-ray log features and core and cutting lithology logs to estimate the depth of these boundaries from
three wells. The Snake Cave Interval consists of ten lithotypes that define three facies associations (FAs) in the three available
wells. These were deposited within three main facies associations: meandering fluvial facies association A (MFFA-A), braided
fluvial facies association B (BFFA-B) and fluvio-shallow lacustrine complex facies association C (FSLCFA-C). The paper
includes a broad description of the significance of lithostratigraphic facies related to depositional environments of the upper
Lower Devonian through the upper middle Devonian succession section.

Structure and Strength of Isothermally Heat-Treated Medium Carbon Ti-V Microalloyed Steel
Journal ArticleIsothermal transformation characteristics of a medium carbon Ti-V microalloyed steel were
investigated using light microscopy, scanning electron microscopy (SEM) equipped with energy
dispersive spectroscopy (EDS), and by uniaxial compressive testing. Samples austenitized on 1100 C
were isothermally treated in the range from 350 to 600 C and subsequently water quenched. The
final microstructure of the samples held at 350 C consisted of bainitic sheaves and had compressive
yield strength, approximately from 1000 MPa, which is attributed to high dislocation density of
low bainite. At 400 and 450 C, acicular ferrite became prevalent in the microstructure. It was also
formed by a displacive mechanism, but the dislocation density was lower, leading to a decrease of
compressive yield strength to approximately 700 MPa. The microstructure after the heat treatment at
500 C consisted of coarse non-polygonal ferrite grains separated by pearlite colonies, principally
dislocation free grains, so that the compressive YS reached a minimum value of about 700 MPa. The
microstructure of the samples heat-treated at 550 and 600 C consisted of pearlite and both grain
boundary and intragranular ferrite, alongside with some martensite. After 600 s, austenite became
stable and transformed to martensite after water quenching. Therefore, the presence of martensite
increased the compressive YS to approx. 800 MPa.
