The Libyan Academy (LA) Administration always aims to develop an integrated system that provides and manages various services for the Libyan Academy, such as student management, educational materials management, human resource management, and other systems. Suggested approach Student Information System (SIS) aims to digitise student system processes by developing a Student Information System (SIS) based on Google Cloud Platform (GCP). A set of components are...

The study aims to identify the problems and obstacles facing researchers in research centers affiliated with the Libyan Authority for Scientific Research, as it is the only Libyan institution concerned with researchers, through submitting research proposals and then implementing them, as well as when publishing in scientific journals and periodicals classified in local and international databases if possible. It also aims to reveal statistically significant differences between the mean...
A number of methods have been established to estimate the proportion true null hypotheses in multiple testing under the assumption of independency. On other hand, the test statistics are either discrete or continuous. In this paper, we will review an existing likelihood approach for estimating the proportion of true nulls controlling the false discovery rates when the test statistics are continuous (see Hualing and Hanfeng, 2021). We therefore present an extension of...

Aircrafts maintenance is a major and complex activity with aiming to achieve high standards of safety and attain an increased level of reliability of system at the lowest possible cost. therefore, estimation of failures risk of aircrafts has become necessary. The paper aimed for estimating failures risk in order to determine an optimal time for starting in the maintenance activities using Fault Tree Analysis (FTA) approach. The FTA approach uses scenarios to identify...
The material balance MB method is a powerful technique used to study reservoir performance and describing the important properties of the reservoir, including the estimates of original oil in place, and the strength of aquifer. It also provides the understanding of drive mechanisms at work, such as solution gas, water influx, and gas cap. This study aims to determine the original oil in place of the Farrud reservoir using both Volumetric & Material Balance...

The purpose of this paper is to be an Approach for Re-Engineering Organization especially in the area of management structure and other areas when it is appropriate, to improve the performance of MISK Company (Media plus co, Ibrize co, Saadda co and Kema co.). This project reveals that MISK has too much centralization that gives it inflexible and bureaucratic structure, decisions made far from specialist's level, poor coordination and experienced duplication, which is...
This paper introduces a mathematical and numerical analysis of a packed bed containing spherical capsules filled with phase change material (PCM) for latent cool thermal energy storage (TES). The considered bed is the cylindrical tank and containing spherical capsules arranged in a random form. According to the energy balance on the PCM and the heat transfer fluid (HTF), the governing equations and boundary conditions are derived at transient conditions and used a continuous phase model...

Two different types of surfactants one ionic surfactant and the non-ionic surfactant were used in this stage. The surfactants were dodecyl sulfate (SDS) and Sorbitan monooleate (Span 80) respectively. The kinetic study was carried out in PMMA seeded growth with the two different surfactants and it found that the conversion time of monomer into the polymer with span 80 was longer than the conversion time with SDS. Emulsion Copolymerization of P-Methyl Styrene with Methyl Methacrylate takes...
A time series is a collection of data that was compiled chronologically. Most time series can be predicted based on their present and historical values. Software programs like SPSS and Minitab are made specifically to process time series data. The SPSS and Minitab software programs can be used to create the autoregressive integrated moving average (ARIMA) model, a time series forecast technique. In this paper, the forecasting process using the ARIMA model is illustrated using the SPSS and...
