Desalination of brackish and salty water is one of the simplest and economical processes to convert it into potable or drinkable water. But solar still has a low productivity device as its main flaw. Mechanisms for heat exchange play a significant part in increasing the daily yield. The output of any solar desalination system is influenced by the water temperature. The productivity rises as the basin's water temperature rises. A series of experiments were conducted for four different cases in the current study, and it was discovered that the still combined with a parabolic concentrator and stepped basin is the most productive and efficient. The results were verified using mathematical modeling, and it was discovered that in all of these instances, the percentage RMS values range from 10% to 40% and the coefficient of correlation is varies in between 0.8 to 0.99. The overall thermal efficiency of 16.54% is obtained for the integrated system when coupled with evacuated tube collector.","PeriodicalId":365908,"journal":{"name":"3C Empresa.

In order to reduce the manual calculation and increase the prediction efficiency, as well as to unify the scoring criteria of previous years, this paper proposes a comprehensive performance prediction model based on deep neural network algorithm. First, principal component analysis is used to transform multiple attributes with strong correlation into independent attributes that are not related to each other, and to reduce the time and space for model training by eliminating redundancy. Second, a back propagation (BP) neural network algorithm is used to build a physical fitness test prediction model, and the model is applied to the test dataset for model performance evaluation. Finally, the physical fitness test model was applied to other years for comprehensive performance prediction, and the differences between the model prediction results and the actual teachers' manual calculation results were observed. The results showed very good prediction results for 2021, in which 92.95% of the data had an absolute value of error less than 2 and only 0.06% had an absolute value of error greater than 4, which indicated that the prediction performance of the model was extremely significant. At the same time, a new athletic athletic scoring standard was also developed based on the neural network BP model to provide a more scientific theoretical basis and guidance for the evaluation of athletic ability of athletes.","PeriodicalId":365908,"journal":{"name":"3C Empresa.

It has several advantages over other metallic materials because it is biocompatible and degradable now being used for biomedical applications, including elimination of stress shielding effects, enhancing degradation properties and enhancing biocompatibility concern in vivo, eliminating the second surgery for implant removal. Bioabsorbable magnesium (Mg) and related alloys have been limited in their usage because of its lower corrosion resistance. Surface alteration and functionality, in addition to basic alloying, is an important technique to deal with Mg and its alloys' reduced corrosion resistance. Magnesium's rapid depreciation however is a double-edged sword because it's critical to match bone renewal to material corrosion. As a result, calcium phosphate coatings have been proposed as a way to slow down corrosion. There are various possible calcium phosphate phases and their coating methods and can give a few distinct properties to various applications. Despite magnesium's lower melting point and greater reactivity, calcium phosphate coatings require precise settings to be effective. Because of their toxicity, non-biodegradability, and much higher cost, the recently used inorganic conversion coatings are less appealing and their application is limited. Conversion coatings are a viable alternative technology that is based on a cost- effective, environmentally friendly, and biodegradable organic component. Surface chelating functional groups in these compounds allow them to link with the magnesium/surface hydroxide layer while also providing anchoring groups for the polymer topcoat. Nanoreservoirs with multilayer inhibitors for active self-healing corrosion resistance thrive in this environment. This study examines the organic conversion coatings for Mg and its alloys in depth.","PeriodicalId":365908,"journal":{"name":"3C Empresa.

It is axiomatic that substantial data should be acquired for a comprehensive model. The WEF nexus simulator may therefore be built to any extent by using simulated data future integral field spectroscopic (IFs and THENs) for WEF nexus interaction. The required data was then organized, and interactions (IFs and THENs) between the three subsystems were investigated. These IFs and THENs aid in our understanding of and ability to address the intricacy of the WEF. Given that the present study’s objective is to review various solutions for WEF Nexus We can now use these classifications to simplify the WEF nexus idea. In other words, the relationship between the three subsystems is demonstrated by the IFs and THENs variables. It would make sense to remove one of the following THEN variables from one subsystem if one of the IF variables in another subsystem remained. Because earlier Nexus initiatives did not provide information on how to initiate and discover interactions, it will be simple to determine interactions. This study demonstrates how a thorough nexus simulation model can access and communicate a wide range of data. The nexus model's interrelationships and interactions with other subsystems can be easily recovered thanks to this classification approach, and none of them will be missed because of ignorance of the nexus system. These IFs and THENs variables are also seen to be an excellent way to simplify the implementation of the Nexus system. The overall score for each project was then calculated by adding the weighted scores, which provided a methodical and objective way to rank the 29 irrigation and hydroelectric dam projects. This study is the first study in Iraq about water-energy and food nexus and helping to streamline decision-making at the nexus due to the size of the several sectors in the Iraqi human society Following input from NWDS stakeholders, three new factors to take into account when deciding which irrigation project options to pursue were identified: a) Fighting poverty; b) Building irrigation projects close to Iraq's borders to ensure border security. 3) Rural Population Decline or Poverty Exodus. It's important to note that the nation places the highest priority on these three factors (Key Priorities National). Irrigation projects may now be planned in a deliberate manner that takes into account the observations of the relevant authorities thanks to the adoption of these aims together with the strategic assessment criteria.

Most smart devices require people to participate in control and cannot actively provide services for people. In response to the above problems, this research proposes a smart factory based on a deep network model, which is capable of data mining and analysis based on a huge database, enabling the factory to have self-learning capabilities. On this basis, tasks such as optimization of energy consumption and automatic judgment of production decisions are completed. Based on the deep network model, the accuracy of the model for image analysis is improved. Increasing the number of hidden layers will cause errors in the neural network and increase the amount of calculation. The appropriate number of neurons can be selected according to the characteristics of the model. When the IoU threshold is taken as 0.75, its performance is improved by 1.23% year-on-year. The residual structure composed of asymmetric multiple convolution kernels not only increases the number of feature extraction layers, but also allows the asymmetric image details to be better preserved. The recognition accuracy of the trained deep network model reaches 99.1%, which is much higher than other detection models, and its average recognition time is 0.175s. In the research of machine vision technology, the smart factory based on the deep network model not only maintains a high recognition accuracy rate, but also meets the real- time requirements of the system.","PeriodicalId":365908,"journal":{"name":"3C Empresa.

Pursuant to this, the application of BIM technology in the water supply and drainage engineering of green buildings is proposed. Firstly, the BIM model is built to draw the axis network and axis height and transform the spatial position of family components, which is conductive to addressing the problem of the loss of engineering information. Then, the energy-saving pathways of green building water supply and drainage projects are analyzed, Concretely, the drainage energy consumption can be reduced by decreasing the overall head of the water pump. The pipe resistance and drainage efficiency can be respectively reduced and improved through reasonable selection of parallel drainage pipelines. Also, the principle of \"avoiding the peak and filling valley\" can be adopted to reduce pump operation in peak period and water draining in valley period, thereby saving drainage cost. By optimizing the control strategy of the drainage system and improving the utilization rate of water resources, the final results of the study show that BIM technology can realize 69% energy saving of the total savings in water supply and drainage engineering of green buildings, decrease cost consumption and improve the quality of water supply and drainage system, so as to make full use of limited water resources to achieve the effect of energy conservation and emission reduction.","PeriodicalId":365908,"journal":{"name":"3C Empresa.
