A Modeling of the Compressibility Effects on the Turbulent Shear Flow | Chapter 2 | Science and Technology: Recent Updates and Future Prospects Vol. 9


Due to its great ability to capture almost all the characteristic properties of turbulent structural flows, the second-order model is successful in many different interest industries and environment complex problems. These successes are attributed to the modeling advances of the pressure strain correlation which controls the strong changes in the turbulence anisotropy. For this reason, this term is regarded as a modeling Carrefour in this chapter. In the present work, compressible models involve the turbulent Mach number. the gradient Mach number and the convective Mach number for this term are examined in different cases of the compressible homogeneous shear flow and the developed mixing layers. Comparisons to the universal models and the accepted numerical data show that the modeling of the pressure strain can be useful for studying and then understanding the structural compressibility effects.

Modelling and Sustainable Management of Sludge in Drinking Water Treatment Plants: A Case Study from Meknes, Morocco | Chapter 2 | Engineering Research: Perspectives on Recent Advances Vol. 9

 

Water management is a key pillar of sustainable development. Indeed, the rational use of water has become a condition for new investments in the water sector, as in many sectors. Optimising the production of drinking water is one aspect. This optimisation involves not only the choice of water resource use but also the management of by-products of the water treatment process to manage sustainably the exploited water resources. The objective of this study is to provide water treatment operators with a tool to attain the most effective management of the facility's by-products and in consequently optimise the cubic meter price of the treated water.

 

The city of Meknes is watered from two sources and a set of holes (14), The turbidity of water sources can vary depending on rainfall recorded in the region. A water treatment plant (600 l/s) was performed for the purification of water sources. Through this study, we focus on the modelling of the sludge volume produced by this plant. As in the construction field, WTP sludge is very important in the pottery sector. A study proposed the use of a mixture consisting of sludge (85%) and sand (silicon dioxide), 15%, in pottery manufacturing.

 

The objective is to design a model for calculating the sludge volume from the actual data recorded in the plant. The model can be used by the operator to predict the sludge volume and can also be used by the designers.

 

The results of this study demonstrated that the volumes calculated from the model constructed considering the data recorded at the station perfectly match the volumes produced, with a determination coefficient of 100%.

 

This paper has presented some preliminary results concerning the challenging task of modelling the sludge volume produced by the water treatment plant using a model. The application of this model can not only provide the operator with an effective tool for managing the station by-products but also provide designers with a formula to prevent over-/under design of structures. Therefore, these measures help to optimise the cost of production of drinking water and will play an important role in the sustainable development of water resources. Therefore, it is reasonable to consider this approach to be applied in the treatment plant for water with a similar turbidity level.

Predicting Rice Crop Yields in Prayagraj: A Comparison of Regression Techniques and Neural Networks | Chapter 3 | Geography, Earth Science and Environment: Research Highlights Vol. 5

This study investigates rice crop yield prediction in Prayagraj District, Uttar Pradesh, using twenty-nine years of historical weather and crop yield data from 1991 to 2019. The analysis divided the dataset into a calibration segment comprising 90% of the data over 26 years, with the remaining 10% used for validation. In our approach, 75.9% of the data was used to train an artificial neural network (ANN) model, and 24.1% was employed for testing and validation to ensure 100% model efficiency evaluation. Techniques such as stepwise linear regression and neural networks were applied to predict rice yields. The performance of these models was measured primarily by the Normalized Root Mean Squared Error (nRMSE), with the regression-based model achieving superior performance, indicated by the lowest nRMSE values. The study also noted the critical role of Bright Sunshine Hours, which demonstrated a significant predictive power with an nRMSE of 0.00025 and a coefficient of determination of 0.94.

Estimation of foF2 Using Global Model of Ionospheric Slab Thickness (GMIST) During January 15, 2022 Tonga Eruption | Chapter 7| Emerging Issues in Environment, Geography and Earth Science Vol. 6

 

The performance of the global model of ionospheric slab thickness (GMIST) in terms of F2 layer critical frequency (foF2) estimation is evaluated during ionospheric disturbances caused by Hunga Tonga-Hunga Ha’apai (HTHH) eruption on January 15, 2022. Hourly values of foF2 estimation using GMIST with TEC input of global ionospheric map (GIM) are compared with foF2 observations from ionosonde stations. For this purpose, the correlation coefficient and deviation are calculated at different locations of ionosonde stations. The GMIST foF2 and ionosonde foF2 at the nearest HTHH have the largest at about 5MHz and the longest deviation during about 14 hours. The trend of the deviation decreases as the distance of ionosonde stations from HTHH increases. The trend indicates the effect of HTHH eruption on the ionosphere involves neutral wind that causes total electron content and foF2 are decrease in different levels. Meanwhile, the correlation coefficients between GMIST foF2 and ionosonde foF2 are not influenced by HTHH eruption. The results show that the HTHH eruption affects the GMIST foF2 performance, especially near the epicenter. Overall the daily mean absolute deviations vary from 0.3 MHz – 1.55 MHz. Hence the GMIST model is feasible to be used for HF communication prediction, especially during quiet ionospheric conditions, and necessary to be updated using real time ionosonde observation, especially after extreme vulcano eruption.

Study about Rheological Behavior of Human Blood: Interrelationship between Two Models| Chapter 1 | Current Perspective to Physical Science Research Vol. 9

 Existing models of viscosity including models Carreau-Gambaruto and Quemada, are approximate because it is difficult to introduce all the factors affecting the viscosity. The viscoelasticity of blood and the newly established viscoelasticity of plasma should bring more light to blood rheology. Medical, fluid mechanics and rheology experts are still quite interested in the flow of blood. There are many models that exist that show the apparent viscosity as a function of shear stress; we will focus on the Quemada and Carreau-Gambaruto models for our discussion. The comparison between models and viscosity measurements showed discordance for shear rates below a few tenths of s.-1. The existence of an inflection point on the experimental curve is probably related to a system relaxation due to the rupture of the red blood cell structure named rouleaux.

Conceptualizing an Ideal Policing Model: Strategies for South African Police | Chapter 6 | Recent Research Advances in Arts and Social Studies Vol. 3

This branch conceptualize a perfect policing model and corruption-fighting tactics for the South African-american police aid. Controlling crime is the lawman's primary goal.  top arrangement since 1996 when the National Felony Prevention Strategy (NCPS) of 1996 was started. This strategy is established a fundamentally new approach by government that is both a multi-agency and multi-body initiative. In particular, it demands the development of wider blame for crime stop and a shift in emphasis from reactive “misconduct control” which deploys most resources towards replying after crimes have before been committed, towards full of enthusiasm "crime stop" which is aimed at forbiding crime from occurring. All generally supports professional crime fighting as the basic policing technique cause it represents a forceful dedication to this goal. Added recommended strategies, aforementioned community policing or logical, seem to be concealing the main point. These hopeful undesirable alternatives if they raised the risk of criminal victimization in the community. But when evaluating the value of alternative police strategies in crime control, individual must look beyond words or just declared assurance to the cause; one must look for showed effectiveness in achieving the objective. Contemporary's professional crime-fighting tactics include three primary actions: motorized patrol, prompt emergency reaction, and retroactive crime examination. Over the past few decades, police openness has been improved by joining officers accompanying the public via telephones, radios, and machines as well as by matching policeman schedules and locations to anticipated entails service. The field will know it has a more forceful policing plan possible if they are successful in the next three to five years at two together decreasing major evil and winning over the public's support. The aim of problem-solving and community protect is to base a close, as opposed to a remote, friendship with the community.

Dispersion Models for Waste Stabilization Pond: A Comparative Analysis | Chapter 6 | Advances and Challenges in Science and Technology Vol. 7

 Dispersion number (d) is ultimate basic determinant of measurement in hydraulic shaping of pollution in waste counterweight ponds and its veracity is important to measure the characteristic practice of pollutants in the puddle. Tracer experiments were performed in a workshop channel to determine aggregation of solute and dispersal number for different flows through the channel. Two forms of sample collection were selected: (1) constant-opportunity-variable-distance and (2) neverending-distance-variable–occasion apperoches. Five dispersion models secondhand in the determination of dispersal number in waste stabilization ponds that is to say Levenspiel and smith [1], Liu [2], Polprasert and Bhatarai, Taylor [3] and Agunwamba and Uneke [4] were used to decide the phenomena and distinguished. Model calculations demonstrated that Liu’s model is closest to that of Levenspiel and Smith that is used as standard for tracer aggregation measurement dispersal number in ponds. Lui’s model may before be used for design of new ponds. Agunwamba’s model trails after Liu’s in nearness but overestimates peak aggregation by about 3 times the calculated. It is however better than Levenspiels on account of it is time conditional and cost effective. Unlike Liu’s model, Agunwamba’s model cannot be secondhand in design of new ponds.

Development of Non-linear Mathematical Models for Mouse Cell’s Conductivity in Pulsed Electric Field | Chapter 07 | Current Topics on Chemistry and Biochemistry Vol. 1

 Based on approximation by algebraic and transcendental functions, non-linear mathematical models were built for the empirically observed dependences of the conductivity of mouse reproductive and embryonic cells on the strength of the pulsed electric field applied. To estimate experimental data, the least squares method was employed. Extrema, inflections, crossings, and curvature of approximating functions were all discovered. These distinctive points were determined using typical mathematical analysis methods. This was accomplished using well-known analytical geometry and algebraic methods for solving equations. In order to calculate the coordinates of junction positions and curvature, the 1st and 2nd derivatives of non-linear functions were also computed. A link has been established between the estimated coordinates of distinctive spots and the modes of membrane electroporation during the linear growth of electric field intensity applied to a cell. The intensity of a pulsed electric field may be computed using mathematical models of experimental conductometric curves, which is necessary and sufficient for the implementation of any electroporation-based electro-manipulation technologies.

Improvement of PID Controller Based on Expert System (Neural Network)| Chapter 4 | Novel Perspectives of Engineering Research Vol.7

 The proportional integral derivative PID controller was improved with the use of a Neural Network and simple hardware implementation, which will improve the control system in our high-turnover industries. The multilayer perception model is the most often used neural network model (MLP). Because it requires a desired output sequence to learn, this sort of neural network is known as a supervised network. However, we present a non-linear control of a stochastic differential equation to Neural Network matching in this paper; the model has been validated, analysed, and compared to other current controllers. The objective is to have control systems in our process industries that can achieve, improve, decrease waste, and are more flexible in terms of conversion level, as well as track set point change and reject load disturbance. This research is a first attempt at designing a simplified neutral network and proportional integral derivative PID control system for a class of non-linear processes, as well as characterising their operational features. Finally, by remodelling the proportional integral derivative PID controller with Neural Network Technique and connecting the plant process control, we were able to achieve a good result where all of the traditional proportional integral derivative PID controller's features were retained and improved using MAT-LAB. The result was great since the process industries' waste and loss were dramatically reduced to a bare minimum.

A Case Study of Time Series Analysis to Forecast the Number of Patients with Tuberculosis in Khartoum State from 2007 to 2016 | Chapter 12 | New Innovations in Economics, Business and Management Vol. 5

 The number of tuberculosis (TB) cases in Khartoum state was predicted using time series analysis. It is based on data collected from tuberculosis patients between 2007 and 2016. The investigation was successful in determining the optimal data model of order (2) ARIMA (2, 1, 0). The study's most noteworthy finding is a quartile-based projection of the number of people with tuberculosis in the next four years. As a result, the predicted value was found to drop and represented the source time series data. The study's ineffectiveness derives from the utilisation of TB data and, as a result, the estimation of future patient numbers, which benefits both patients and specialists.

The Effects of Illegal Small-scale Gold Mining in Ghana: A Threat to Food Security | Chapter 07 | Emerging Challenges in Agriculture and Food Science Vol. 3

 Ghana has an abundance of mineral and agricultural resources. Gold, bauxite, diamonds, and manganese are among the commercially mined minerals. Others, such as kaolin, salt, limestone, mica, and feldspar, to name a few, are either underutilised or completely unutilized. The major agro-ecological zones also happen to correspond with the largest mineral resource reserves. Illegal small-scale gold mining (galamsey) destroys fertile land in agro-ecological zones, lowering agricultural output and jeopardising food security in Ghana. Using secondary data such as Ghana's agricultural productivity records, consumer price indices for food commodities, and national food import statistics, this article examines the impact of illegal small-scale gold mining in Ghana through the lens of a conceptual model that links galamsey and agricultural productivity, in terms of the realistic threat to food security. The data demonstrate that over the last few years, key galamsey regions (Ashanti, Brong Ahafo, Eastern, Central, and Western) have seen progressively worse food productivity and, as a result, higher Consumer Price Indices than the national averages (from 2012). Agriculture's contribution to GDP fell in lockstep with mining's throughout the same time period. Galamsey by surface mining is largely responsible for low food production, food price spikes, and high cost of living, especially in galamsey-prone regions of Ghana, by degrading arable lands, contaminating water bodies, polluting the air, shifting labour from food crop farming to mining, and displacing farmers. However, if reclamation is done well, surface mining can be a short-term land use that can be followed by profitable cropland. Land reclamation from degraded open cast mines will increase agricultural productivity and eliminate yield gaps in crops, allowing the government to achieve food import substitution for major food staples such as rice and wheat. As a result, national food import dependence, food import bills, food price rises, and the cost of living will be reduced. As a result, reclamation of degraded galamsey-mines is critical to achieving all three dimensions of the United Nations' Sustainable Development Goals (social, economic, and environmental), particularly goal two of the Post-2015 Agenda (end hunger, achieve food security, improve nutrition, and promote sustainable agriculture). As a result, the author proposes mandatory reclamation of degraded surface mines for arable use as a long-term solution to Ghana's food insecurity problem. Food insecurity is a real and present danger!

Teacher Motivation for Quality Output | Chapter 07 | Current Research in Language, Literature and Education Vol. 2

 In human management, motivation is critical. Motivation has been found to improve teachers' production, according to empirical research. The amount of effort put in to achieve school objectives is determined by teachers' feelings, behaviour, associated value (worth), and the surroundings. Teachers that are happy with their jobs are more productive and can have an impact on their pupils' grades. The concept of motivation is explained in this chapter, as well as models of motivation for teachers' production. It also has as a purpose to explore how instructors might be encouraged to perform better in their teaching jobs by elaborating on the element of teacher motivation and output. It was shown that boosting teachers' morale, promoting them, providing a decent work environment, and having pleasant interpersonal interactions all had a favourable impact on their performance.

Determination of Climatic Impact of Temperature in Presence of Avian Respiratory Infections in Villa Clara Province, Cuba | Chapter 5 | New Frontiers in Medicine and Medical Research Vol. 16

 The goal of the study was to see how temperature affected avian respiratory diseases in the region of Villa Clara, Cuba. During the period 2005-2007, retrospective data were used to acquire epizootiological statistical information on susceptible and deceased chickens about avian respiratory diseases in specialist poultry farms in Villa Clara province. These figures were compared to the average temperature stockings for this time period in this county. The entire number of deaths was linked to the total number of susceptible people, who were linked to the provincial temperature stockings. The model Autoregressive Integrated Moving Averages (ARIMA) of Box-Jenkins Methodology was used for data processing utilising the statistical tool SPSS Version 13. Multivariate regression techniques were also used to model the total number of poultry deaths. According to the final ARIMA model, a one-degree increase in temperature resulted in an increase of 53.37 fatalities. A 95 percent probability value was also employed. In the study area of Villa Clara province, Cuba, this investigation permits confirming and quantifying the impact of mean temperature on susceptible and poultry fatalities. It was discovered that for every 1oC increase in monthly half temperature, there will be an increase of 8 894 susceptible cases, and for every 1000 susceptible cases, there will be an increase of 6 birds, implying that the susceptible cases will be roughly equal to the total number of deaths.
