From ancient times to the present day, the wind has been consistently recognized as one of the most important, accessible, and environmentally friendly energy sources, which today has a significant share in global electricity generation. The limited resources of fossil fuels are running out day by day, and the exploitation of this type of energy produces harmful pollutants. Consequently, double attention is paid to wind power and similar free and sustainable resources. Attaining the optimal location for establishing wind farms and turbines preeminently reduces construction/transmission costs and energy-related losses. In light of the above, we employ several artificial intelligence (AI) algorithms to optimally identify and locate the grid-connected wind farms, significantly serving electricity energy manufacturers and distribution companies. In addition, this study aims to maximize the efficiency of the wind energy system by considering the critical factors influencing the production capacities, such as wind speed, air density, turbine size, and geographical location. This work leverages an image processing-based technique, density-based spatial clustering of applications with noise (DB-SCAN), k-means, fuzzy c-means (FCM), and k-medoids machine learning algorithms. Numerous experiments and simulations are designed and performed exploiting MATLAB/Simulink, all of which demonstrate the substantial superiority of the proposed systems.

This paper proposes a framework that will be discussed for the smart recognition of individual identification information for COVID-19 APPs. An example of these APPs is AL HOSN APP in the United Arab Emirates. The study will evaluate the identification of an individual that contains information regarding PCR results and COVID-19 Vaccine results. Such data entry enables users to access places while lowering the chances of face-to-face contact. The proposed framework will ensure complete security to prevent abuse of individual’s personal information. Furthermore, importance of detection mechanism with hardware compatibility is taken into account to ensure a complete smart process from scanning process to validation of results.

The Latent heat storage (LHS) based on phase change materials (PCMs) has a critical part to demonstration in preserving and efficiently utilizing energy, resolving demand-supply mismatches, and boosting the efficiency of energy systems. However, they have a low thermal performance inherent in it because the low thermal conductivity (TC) of PCMs. Paraffin organic PCMs have several advantages such as higher LHS, nontoxic, abundant in nature and inexpensive, whereas TiO2 nanoparticle is type of hydrophilic group having tendency to improve TC. In this research TiO2 in different concentration (0.1, 0.5, 1, and 2 wt percent) with surfactant sodium dodecyl benzene sulphonate (SDBS) added into Paraffin RT44 HC PCM using two step techniques, and the thermophysical properties were broadly discussed. Thermogravimetric analyzer (TGA), Fourier transform infrared spectroscopy (FT-IR) and Thermal property analyzer (TEMPOS) were used for the characterization of prepared composite nano-enhanced phase change materials (NePCM). Additionally, the effect of nanoparticles on TC was investigated. The highest TC was obtained with PW/TiO2-1.0 by an increment of 86.36% as related with base PW. The FTIR spectrum of the composite PW/TiO2 confirmed no interaction between PW and TiO2, resulting in a more chemical stable composite. The addition of TiO2 to PW enhanced the degradation temperature to 10℃ by making it more thermal stable. Grounded on the results it can be concluded that the developed composite is suitable for thermal energy storage (TES), photovoltaic thermal (PVT) systems, and hot water applications.
基于相变材料的潜热蓄能技术在能源保护和高效利用、解决能源供需不匹配、提高能源系统效率等方面具有重要意义。然而，由于pcm的低导热系数(TC)，它们具有较低的固有热性能。石蜡有机pcm具有LHS高、无毒、含量丰富、价格低廉等优点，而TiO2纳米颗粒是一种亲水基团，具有改善TC的倾向。本研究采用两步法将不同浓度(0.1、0.5、1、2%)的TiO2与表面活性剂十二烷基苯磺酸钠(SDBS)一起加入到石蜡RT44 HC PCM中，并对其热物理性质进行了广泛的讨论。采用热重分析仪(TGA)、傅里叶红外光谱分析仪(FT-IR)和热性能分析仪(TEMPOS)对制备的复合纳米增强相变材料(NePCM)进行表征。此外，还研究了纳米颗粒对TC的影响。当PW/TiO2-1.0时获得的TC最高，与碱PW相关的增量为86.36%。复合材料PW/TiO2的FTIR光谱证实PW和TiO2之间没有相互作用，因此复合材料的化学稳定性更高。TiO2的加入使PW的热稳定性提高，降解温度提高到10℃。结果表明，所研制的复合材料适用于热储能(TES)、光伏热(PVT)系统和热水应用。

This paper proposes an investigation of L-shaped piezoelectric composite beams to generate electric power. The objective is to increase the bandwidth of the frequency range to harvest the energy. The structure is formed by one 150mm auxiliary piezoelectric composite beam and one 75 mm main piezoelectric composite beam, one tip masses. The tip masses on the 75 mm main composite beam are varied to determine the frequency range to harvest energy. The capability to control the frequency bandwidth about which energy is harvested is illustrated by adjusting beam lengths properly. This device has been found to provide that the output power and energy harvesting efficiency over the L-shaped structure’s frequency range is greater than the cantilever structure’s output power and energy harvesting efficiency under the same excitation conditions. The power densities of the different configurations are compared.

The design and development of a vehicle chassis is of a high significance in the aviation industry. This is due to its vital role in supporting the main structure of the vehicle in both static and dynamic conditions. It provides enough space to carry the various components of the vehicle. Therefore, it should be strong enough to withstand the different types of stresses. In current work, the tubular frame chassis of Dynali H3 2-seater helicopter is modeled with CATIA V5 and simulated using Ansys Static Structural Software by implying Finite Element Analysis (FEA) method. The main aim of this work is to perform structural analysis on the existing frame using the derived static loading acting on the tubular frame. The analysis focused on the structural loading using static loading only aiming at improving the tubular spaceframe chassis strength and design integrity of the current model in such a way that stresses are minimum, and the performance is maximum. The proposed design experienced less deformation and stresses compared to the current frame under the same static loading.

This paper measures the overall, technical and scale efficiencies of public hospitals surgical services and explores strategies to improve efficiency. Composite Data Envelopment Analysis (DEA) models that accommodating ratio variables are developed to measure efficiencies, and offer improvement strategies. Results show that overstayed patients can be minimized by 9% and 6% for overall and technical efficiency to operate efficiently. Decreasing the scale of the surgical service department will not improve efficiency. In conclusion, the number of hospitalized-discharged patients showed to be the most contributing factor to efficiency for outputs, and patient turnover rate among the input. It is recommended that inpatient throughput be improved and patient overstay be minimized, also, the operational and personal management should be enhanced to utilize resources.

Construction industry is the most important sector that contributes to the economic growth of a nation. However materials waste resulting from construction activities represents a threat to the ecological system and affects the sustainability of the construction industry negatively. Consequently a reliable waste disposal method should be selected to avoid any adverse environmental and human impacts. There are many methods to discard materials waste such as landfills, incineration, recycling, reuse and reduction. Each method has its own features, characteristics and effects on environment and human health in addition the selection of the appropriate method depends mainly on the nature of the waste. The common and preferred method by construction companies is landfills, but this method affects environment and human health harmfully. The aim of this study is to evaluate waste disposal methods in terms of energy consumption, risk of pollution, practicability, quantity of waste, cost efficiency, favorability, effectiveness, quality in managing waste and environmental effects. The evaluation was made using Fuzzy Promethee which is the most well-known tool of Multi criteria Decision Analysis (MCDA). The analysis ranked reduction of materials waste as the best alternative followed by reuse and recycling according to the weights and the majority of criterias specified while the incineration ranked as fifth and landfills was ranked as the last alternative, which is not preferred for the environmental health.
