The corner palace of King Faruq I is located on the eastern side of the Nile River, and the fountain in question is located in the palace, which consists of a central octagonal axis that stands out from four facades, four heads of seven are in a perpendicular position, and four human statues are based, two of them for two children and the other for two men who took into account the aesthetic and anatomical proportions.The Helwan Corner Fountain, which is located inside the courtyard of the palace (Rukn Museum in Helwan), is one of the most important and most beautiful designs of archaeological marble fountains in terms of structural and artistic design.Soil mechanics and weathering have played a large role in damaging that fountain, so serious manifestations of damage have appeared, including the decomposition of the surface of the fountain statues and the appearance of some cracks and blooming salts on the surface from the influence of the capillary property in addition to the chemical reaction that occurred as a result of the presence of that fountain in an environment with a high percentage of gases Acid like carbon dioxide, sulfur dioxide, carbon monoxide, and oxygen in addition to the high rate of evaporation in the region, where the region is considered one of the most important areas of high pollution for an industrial city, which is the city of Helwan.The fountain suffers from a high percentage of minerals appearing in the form of salts and the multiplicity of shapes and sizes of their crystals for their diversity, including sulfur, carbon and chloride minerals, in addition to the influence of mechanical movement of the fossil soil mass (the subject of the research)Where the fountain is eclipsed in the courtyard of the palace in an industrial area, which is Al Tebeen, where factories abound without a filter to purify the air of the resulting gases such as carbon dioxide, sulfur dioxide, and others.In addition to the traffic from heavy and light trucks on the adjacent roads, which leads to damage to the fountain through the movement of soil.

Optimal sizing and management of hybrid wind turbine-diesel-battery system for reverse osmosis seawater desalination in NEOM city is the objective of the paper. Therefore, the paper explored the different factors to optimize and introduce a technoeconomic evaluation and energy management of a stand-alone wind turbine (WT) system, diesel generator (DG), and battery storage (BS). The suggested WT/DG/BS system is implemented to feed seawater reverse osmosis (SWRO) unit in NEOM. The necessitated desalinated water per day is 100 m3. To determine the optimal size of WT/DG/BS corresponding to the minimum cost of energy (COE) and net present cost, two different ratings of the SWRO units (SWRO-100 and SWRO-150), three control dispatch strategies (load following, cycle charging, and combined dispatch), and five types of batteries are considered. HOMER software is performed to simulate and optimize the WT/DG/BS. The optimization results indicated that the best battery storage is the Trojan SAGM battery. In this case, the COE ranged between $0.337/kWh and $0.564/kWh. The lowest COE of $0.377/kWh is obtained when using a combined control strategy and SWRO-100 unit, whereas the worst COE of $0.564/kWh is obtained when using load following control strategy and SWRO-150 unit. The best option of the WT/DG/BS system to supply the SWRO unit is option number 26. This system includes one wind turbine of 90 kW, DG of 25 kW, 47 Trojan SAGM batteries, a 23.8 kW converter, a SWRO-100 unit, and a combined control strategy. The net present cost and the initial cost are $950,725 and $221,495, respectively. The annual operating cost and annual consumed fuel are $56,409 and 36,396 L, respectively. Compared with using only a 25 kW diesel generator, the COE reduced from $0.373/kWh (using only DG/BS) to $0.337/kWh (using the best option) by around 9.65%. Under this condition, the values for the internal rate of return, return on investment, and simple payback are 11%, 7.8%, and 8.3 years, respectively. [ABSTRACT FROM AUTHOR]

The equaliser is an indispensable block inside the receiver in Serial Link systems. It is used to moderate the high-frequency loss of the signal in the channel. A new technique is described to improve the performance of the Continuous-Time Linear Equaliser (CTLE). This technique utilises split-length device (SLD) in order to boost the output impedance of the SLD. The proposed CTLE is designed and simulated in 65 nm CMOS technology. Post-layout simulation results demonstrate that the proposed technique has more peaking than conventional CTLE by an order of 1.5 dB at Nyquist frequency. The Proposed design has a vertical eye-opening of 220 mV and a horizontal eye-opening of 0.35 UI. It consumes 1.56 mW from a 1.2 V supply. A FoM of 13.1 fJ/bit/dB is achieved. [ABSTRACT FROM AUTHOR]
