The weather data files follow the seven climate regions and the different cities, starting with Alexandria, then Cairo, Minya, Asyut, Hurghada, Kharga, and finally Aswan.
The simulations will also compare the most recent weather data files for 2021 with the original from 2006 to determine whether they are still applicable to today's energy depletion rates.
The methodology involves employing quantitative research to analyze the impact of climate change on energy consumption rates, utilizing records from ECEEE and Egypt’s weather data files.
The weather data files represent seven climatic regions, with cities including Alexandria, Cairo, Minya, Asyut, Hurghada, Kharga, and Aswan, each corresponding to a specific region.
The study assesses the applicability of these values to current energy depletion rates by comparing recent weather data files from 2021 to the original records from 2006.

Composition of FDS hardware
Reciprocating machinery FDS mainly comprises sensor, data acquisition device and hand-held terminal, and its hardware composition is shown in the following Fig. 1:
In the portable FDS, speed sensor is provided for testing phase information of shaft, and the rest of sensors for sending all the acquired signals to the data acquisition device through shielded cable; and in the data acquisition device, signals that are detected by all sensors firstly enter the input signal conditioning module through cables for filtration and noise reduction so that interference signals are eliminated, those conditioned signals enter A/D conversion module for analog/digit conversion, and then digital data is sent through the data sending module.
Converted data becomes digital, and the digital data finally enters data sending module for sending, which mainly comprises data extraction module, wireless sending module, CAN bus communication module and CAN bus sending module.

Adsorption equilibrium data for each adsorbent
were obtained at pressure up to 1.5 atm.
These diffraction data reveled that Na-X retained high crystalline phase, as evidenced by sharp diffraction peaks at high angle [6].
The diffraction data also demonstrated that no A-type zeolite was present in the adsorbent samples.
Cation exchange gave no damage to the zeolite framework, and furthermore, no reduction in the crystallinity of the ion-exchanged X-type zeolites.
Adsorption equilibrium data for nitrogen and oxygen onto the ion-exchanged X-type zeolites measured at 20 o C and at pressure up to 1.5 atm revealed that Li-X adsorbent showed the highest nitrogen adsorption capability at high equilibrium pressure.

Two strain rates (0.1 and 1s-1), three strains (40%, 60% and 70% thickness reduction) and four temperatures (20, 200, 400 and 600°C) were used: providing a total of 24 deformation conditions.
The EBSD data was acquired in the mid-thickness section of the long transverse plane (plane containing rolling direction (RD) and normal direction (ND)) while X-ray data was acquired on the rolling plane (plane containing RD and transverse direction (TD)).
Data analyses were conducted for g and q fibre grains.
X-ray peak profiles were used to evaluate the dislocation density and X-ray resolution function [8,9], while from EBSD, data for average point-to point misorientation (GAM or grain average misorientation) and number of high angle boundaries inside a grain were determined [10].
Conclusions The highest reduction of 70% shows a clear increase of in-grain misorientation at intermediate deformation temperatures (200-400°C).

Campus energy consumption per unit area in American Research University is higher than most building energy consumption; especially the 24-hour operation of the laboratory and data center consuming a lot of energy, and the total energy consumption of school buildings is second to the comprehensive consumption of various types of office buildings.[1] It has become an undisputable problem that colleges and universities energy consumption is the social major energy consumption, so building energy conservation has come to a critical state in colleges and universities.
In recent years, along with the sustainable development thought is deeply rooted in the hearts of the people gradually, energy conservation and emissions reduction of colleges and universities in our country has been not stay on a conservation-minded campus propaganda and demonstration projects, but the green concept into campus construction and operation management.
Researching energy consumption quota of colleges and universities is one of the important measures to promote energy conservation and emissions reduction.
Through data processing of 41 colleges and universities building energy consumption in Hubei, we came to the conclusion that the per student average energy consumption index of engineering and agriculture in colleges and universities of 211,985 is higher than of liberal arts in colleges and universities generally, generally high to 35.8%; the per student average energy consumption index of engineering and agriculture in colleges and universities of 211,985 is higher than ordinary engineering, general high to 11.08%.
The quota according to the distribution of energy consumption to formulate, and by the combination of related departments of punishment and reward can easily promote the enthusiasm of colleges and universities on energy conservation transformation, but for building samples quantity, data accuracy requires high; The method according to per student building area to formulate is the most scientifically rigorous, And has more advantages to colleges and universities, which is difficult to obtain the accurate energy consumption data in energy measurement, can effectively promote the energy conservation work progress.

This effect is primarily attributed to increased pozzolanic reactivity, resulting in a reduction in calcium hydroxide concentration within the cement matrix.
Consequently, the concrete experiences a loss of its binder materials, leading to a significant mass reduction.
The mass loss data for the CFA system can be seen in Fig. 3(a), which shows that concrete that has some CFA added to it loses less mass than OPC.
For instance, the 30BFA mixture stands out with the most incredible reduction in mass loss, recording an impressive value of -8.04%.

The efforts for implementing green manufacturing activities involve product design changes, the development of new raw materials and the reutilization, recycling or reduction of production wastes.
As data collection procedure to examine the selected case, the semi-structured interview method was chosen because it is considered the most adequate method for collecting data in qualitative research [23, 24].
Patton [25] also reinforces this recommendation saying that the proposed data gathering method should be used when the researcher needs flexibility to obtain information in any direction that could be required, which is the case in this exploratory study.
End of process controls Is there a program for reduction of gas emissions?
The case study makes clear that a company needs the support of its suppliers to improve the environmental conditions of its supply chain, especially when it requires from its vendors actions like reduction, reutilization, recycling, redesign, recuperation and re-manufacturing, all them vital for a better environmental performance.

The novel concept should also enable the online acquisition of measurement data during production operation, allowing the steel strip condition as well as flatness errors to be constantly monitored and detected.
On the one hand, these data can be used to react to fluctuating input parameters and optimize the straightening process.
On the other hand, the use of the data in the sense of Industry 4.0 is also planned, whereby the entire subsequent production process benefits.
This implies a reduction of the reject rate in the production chain, which increases the attractiveness of manufacturing products in small batches in particular.

Effectiveness was compared on the example of the Shanghai–Rotterdam–Shanghai route, which is used extensively and provides realistic data for the model calculation.
This calculation is complemented by data adopted from the Suez Canal Pricing Forecast 2005–2025 prognostic study.
The Maersk shipping company predicts a drastic reduction in transportation costs.
Despite a relatively significant reduction in transportation costs at 19 knots, it is important to consider the increase in shipping time by 9 days, as compared to transport at 23 knots.
Due to this reduction, the ship saves 9 days at a consumption of 120 t/day and at the same time, there will be additional 59 days at a consumption of 105 t/day.
