Egypt have a wealth of heritage and archaeological buildings from prehistoric until the era of the Muhammad Ali family (1805 - 1952), where European influences prevailed in this period, mixed with traditional Islamic styles. Our building in this paper is a tomb dating back to the family of Ismail Sidqi Pasha (1875 - 1950). This building was built before 1900, as the first tombstone dates to 1900, therefore it was built in the period between 1880 and 1900. The roof of the building is considered one of the most building elements vulnerable to damage due to rainwater that accumulates on the roof for a long time in winter, beside insulation material damage, causing Lots of damage to the roof. Consequently, it affected the ceiling decorations.......

We propose a new method to synthesize 1 Hz wind speed and wind power time series data from the industry standard 10-minute wind turbine performance data. The method is based on a parameterized power spectral density (PSD) function decomposed into trend and random components. We illustrate the intra-timestep data synthesis 10 utilizing 1 Hz data from two distributed wind turbines..

It is inevitable that the human race would eventually seek to explore other planets and set foot on them. Chemical Engines are our primary method of traveling across the solar system, especially crewed travel or travel involving very high payloads. However, these engines simply do not possess the efficiency (Specific Impulse) required for fast and frequent Interplanetary travel. Therefore, we suggest the utilization of a nuclear engine, A nuclear gas core open cycle engine. These engines would have the thrust of a chemical engine combined with the efficiency of nuclear fission resulting in an engine with almost 4-8x the efficiency of a conventional chemical engine. We also hope to explore a possible application of this engine.

Analysis of conjugate convective flows and heat transfer performance of built environment has been an interesting research subject because of its technical applications in building design. In this study, we shall investigate the temperature distribution of air in a heated room as well as the conjugate conduction heat flow through the walls and convective heat loss to the surroundings. Conduction occurs in a solid when its ends are at different temperatures. The rate of conduction depends on the thermal conductivity of the solid material and the temperature gradient [1] [2]. A typical heated, non-ventilated domestic room is modelled as a 3D box with an installed heater. The floor and roof are considered adiabatic while heat loss takes place through the walls which are in interaction with the external ambient temperature conditions.

Over the past century, the Indian insurance industry has achieved numerous milestones, evolving into a robust sector characterized by a stringent regulatory framework that safeguards the interests of investors. Among the key players, the Life Insurance Corporation of India (LIC), a public sector undertaking, stands out as the market leader in the life insurance segment. A detailed study focused on Unit-Linked Insurance Plans (ULIPs) was conducted, examining the top five private insurance companies in India. This study aimed to assess the performance of these ULIP products, particularly their dependency on stock market fluctuations, through the use of hypotheses testing.........

This research investigates the potential of TikTok as a learning aid among students. By analyzing knowledge retention and behavioral change, we assess whether TikTok's educational content contributes to formal learning. The study employs quanti- tative methods to measure the platform's impact, offering insights into social media's role in educational settings.
