—Predicting the groundwater level has recently become very important research topic especially with the rise of population density and consequently increasing the water demand. This paper uses the Random Forest and linear regression neural network models to predict the groundwater level of Wadi-Alshaty district in the South West part of Libya. The results are compared with that obtained using the hydrologic long-term forecasting graphical approach. One of the most important findings of this study is the effectiveness of the neural network models to investigate the fluctuation of the groundwater levels over time (20 years)

تتضمن هذه الورقة دراسة عن الجسور وتوظيف برنامج نظم المعلومات الجغرافية GIS لأرشفة معلومات عن هذه الجسور، فمن خلال البحث عن معلومات عن الجسور لدي مؤسسات الدولة المعنية بجسور داخل مدينة طرابلس تبين عدم وجود أي بيانات، مما تطلب حصر معظم الجسور داخل مدينة طرابلس وجمع المعلومات العامة والمتمثلة في ( الاسم، الاحداثيات، الطول، العرض، ومنطقة ربط الجسر) لعدد 51 جسر، وتم عمل دراسة تفصيلية عن ثلاث جسور واجراء فحص بصري ظاهري وجمع البيانات عن حالتها ووظائف عناصرها اذا كانت تشتغل بالشكل المطلوب وما بها من عيوب ام بصحة جيدة وبعد جمع بيانات الفحص البصري وتقييم حالة الجسور تم وضع هذه البيانات في بطاقات وربط كل البيانات التي تم جمعها في برنامج نظم المعلومات الجغرافية لأرشفتها الكترونيا ليسهل الوصول اليها في أي وقت من قبل المهتمين للحصول علي معلومات عن الجسور داخل مدينة طرابلس بطريقة سهلة وميسورة وفي اسرع وقت وتكون خطوة للاستغناء عن الارشفة الورقية. arabic 135 English 3

Abstract Fire is one of the greatest risks for every building and particularly for high-rise buildings. Usually, a building fire causes not only hazard to the occupants in a floor, but also a possible threat to the occupants in other floors and in particular to those located at upper storeys, with rising temperature and with killer smoke. Fire simulation can be performed using software packages designed for such a task. The fire simulation can often include aspects of hazard identification, fire growth and smoke movement, egress assessment, structural fire performance, sprinkler and fire detection system design, and smoke management system specification.The present thesis examines the up-to-date technologies available within the context of fire engineering simulation. This work gives an overview of available software packages that are used today in fire engineering simulation. It presents the procedure of fire simulation inside a high-rise building by using an advanced computer program named the Consolidated Model of Fire Growth and Smoke Transport ) CFAST for short. The CFAST program simulates fire action by calculating fire gases, the evolving distribution of smoke and temperature throughout a building during fire. This computer program is based on solving a set of equations that predict the state variables such as pressure and temperature. These equations are derived from the conservation equations for energy mass and the ideal gas law. It is important to know that the resulting errors, which might result, does not come from these equations, but rather they come from numerical analysis representation of the equations or from the simplifying assumption.
