The structural approach to city image (Al-Madinah Al-Munawarah)

Today there are huge and radical changes taking place in the development of almost all the cities of the Muslim world, among them the city of Al- Madinah Al- Munawarah. These have brought profound changes in ways of life, urban structure and styles of architecture which have permeated and transformed the very social and physical fabric of the cities and are destroying the quality of the urban environment and Muslim way of life. The Muslim city is in danger of becoming a mere copy of the worst elements of many Western cities: ugliness, noise, air pollution, a frenetic way of life and all the associated social problems. Meanwhile it is felt fundamental to approach Islamic civilisation not as a mere object of investigation, with the Muslim city as its museum of historical heritage, but as a living reality, a faith and an inspiration to milliards of people in the world of Islam who do not separate their ethical values and their cultural identity from their demands for social welfare, justice and a humane quality of life within the modern process of economic development. Since we live in the world of the mind, it follows that the problems can be seen as a battle for the mind. In this realm of persuasion and stimulation it is the image which assumes the key role and it is the image makers - the authors, controllers and artists, among them the built environment professionals - who hold a special responsibility. Furthermore it is the reasons and processes underlying the formation of particular interests and images that take on special significance. This is critical if one tries to solve the problems of the formation and development of the symbolic patterns in a historical city such as the city of Al- Madinah, which is known as the City of the Prophet Muhammad (peace be upon him). The author aims to propound a comprehensive study of the patterns of tradition and historic events of the Prophet's time which inspired and generated the form of the city of Al- Madinah. The study focuses on the preservation of the deep images embedded in people's perception of the city in order to project them to sustain its form in the future. Therefore, the author has in mind the objective of conserving Islamic architectural heritage in general, and the necessity of impressing, on the consciousness of the powers that be, the urgency of preserving the heritage of the city of Al- Madinah before it in particular is destroyed. The City of the Prophet must be considered as being on no account expendable, regardless of the gains made in replacing the old by the new. Finally the present study forms a sequel to the findings extracted from literature and from the case study, as related to the Islamic Legal System. Common to all these fields is the view that architecture represents a means to give man an existential foothold, similar to the view of phenomenological approaches. The author's primary aim is therefore to investigate the psychic implications of architecture rather than its practical side, although he certainly admits that there exists an interrelationship between the two aspects. In reviewing the literature, the "structural" dimension is discussed as part of a comprehensive system in transformation. At the same time, the thesis stresses that the environment influences human beings, implying that the purpose of architecture transcends the definition given by structuralism. A discussion of perception and image has been therefore included emphasising that man cannot gain a foothold through scientific understanding alone. He needs symbols, that is, works of art which represent life- situations. It is one of the basic needs of man to experience his life -situations as meaningful, and the purpose of the work of art is to reflect meanings. The concept of "meaning" is also a strong theme throughout thesis

Camera Calibration through Geometric Constraints from Rotation and Projection Matrices

The process of camera calibration involves estimating the intrinsic and extrinsic parameters, which are essential for accurately performing tasks such as 3D reconstruction, object tracking and augmented reality. In this work, we propose a novel constraints-based loss for measuring the intrinsic (focal length: $(f_x, f_y)$ and principal point: $(p_x, p_y)$) and extrinsic (baseline: ($b$), disparity: ($d$), translation: $(t_x, t_y, t_z)$, and rotation specifically pitch: $(\theta_p)$) camera parameters. Our novel constraints are based on geometric properties inherent in the camera model, including the anatomy of the projection matrix (vanishing points, image of world origin, axis planes) and the orthonormality of the rotation matrix. Thus we proposed a novel Unsupervised Geometric Constraint Loss (UGCL) via a multitask learning framework. Our methodology is a hybrid approach that employs the learning power of a neural network to estimate the desired parameters along with the underlying mathematical properties inherent in the camera projection matrix. This distinctive approach not only enhances the interpretability of the model but also facilitates a more informed learning process. Additionally, we introduce a new CVGL Camera Calibration dataset, featuring over 900 configurations of camera parameters, incorporating 63,600 image pairs that closely mirror real-world conditions. By training and testing on both synthetic and real-world datasets, our proposed approach demonstrates improvements across all parameters when compared to the state-of-the-art (SOTA) benchmarks.

Viral Vector Induction of CREB Expression in the Periaqueductal Gray Induces a Predator Stress-Like Pattern of Changes in pCREB Expression, Neuroplasticity, and Anxiety in Rodents

Predator stress is lastingly anxiogenic. Phosphorylation of CREB to pCREB (phosphorylated cyclic AMP response element binding protein) is increased after predator stress in fear circuitry, including in the right lateral column of the PAG (periaqueductal gray). Predator stress also potentiates right but not left CeA-PAG (central amygdala-PAG) transmission up to 12 days after stress. The present study explored the functional significance of pCREB changes by increasing CREB expression in non-predator stressed rats through viral vectoring, and assessing the behavioral, electrophysiological and pCREB expression changes in comparison with handled and predator stressed controls. Increasing CREB expression in right PAG was anxiogenic in the elevated plus maze, had no effect on risk assessment, and increased acoustic startle response while delaying startle habituation. Potentiation of the right but not left CeA-PAG pathway was also observed. pCREB expression was slightly elevated in the right lateral column of the PAG, while the dorsal and ventral columns were not affected. The findings of this study suggest that by increasing CREB and pCREB in the right lateral PAG, it is possible to produce rats that exhibit behavioral, brain, and molecular changes that closely resemble those seen in predator stressed rats

Solar/wind pumping system with forecasting in Sharjah, United Arab Emirates

This paper demonstrates a water pumping hybrid power system design. The proposed system was designed for water related applications in Sharjah (Latitude 25.29 °N and Longitude 55 °E), United Arab Emirates. The proposed water hybrid system has two primary renewable power systems: solar PV panels and wind turbines. The proposed hybrid system considers the changes in weather conditions (humidity, wind speed, and temperature) since wind speed affects the performance of the wind turbines and solar panels are affected by solar irradiance. The following components are involved in the proposed design: battery (to store the power from solar panels), voltage regulator circuit (for getting stable DC voltage), three-phase rectifier (to convert the reduced AC voltage to DC), three-phase transformer (for reducing the obtained AC voltage), and DC electric motor (the main output of the proposed water pumping system). The proposed water pumping system relies on neural network blocks to achieve weather forecasting by obtaining solar irradiance values from the input temperature, wind speed, and humidity in a span of five years. Both MATLAB and Simulink are used simulate the performance of the proposed system under different weather conditions by changing the values according to the measured weather conditions values over five years

Hybrid solar/wind/diesel water pumping system in Dubai, United Arab Emirates

This paper proposes a hybrid power system design for water pumping system in Dubai (Latitude 25.25 °N and Longitude 55 °E), United Arab Emirates using solar photovoltaic (PV) panels, wind turbines, and diesel generator. The proposed design considers the changes in weather conditions (humidity percentage, temperature in celsius, and wind speed in m/s) that directly affect solar irradiance values which alter the performance of the hybrid system. The proposed design deals with the problem of rare rainy days in Dubai between December and March and the high temperature throughout the year since that makes providing water to rural and isolated zones essential. The proposed system uses voltage regulator to maintain stable DC voltage from the solar power system, battery bank to store the voltage from solar PV panels, three-phase rectifier to convert the AC voltage from wind power system to DC, three-phase step-down transformers to reduce the AC voltage of the wind turbine and diesel generator, and DC electric motor for water pumping output. The system used neural network for solar irradiance forecasting over an interval of 10 years (from 2009 to 2019). The proposed system will be demonstrated using Simulink to show the stability and performance under different weather conditions

Role of Waqf in poverty mitigation: A study from South Punjab Pakistan

This study investigated the mediating role of family well-being in the relationship between waqf and poverty mitigation. Using a cross-sectional design, data was collected from 350 respondents in a Malaysian context. The results showed that waqf practices have a direct positive effect on poverty mitigation and family well-being. Family well-being, in turn, partially mediates the relationship between waqf and poverty mitigation. The study provides evidence for the potential of waqf practices to improve family well-being, which can ultimately contribute to poverty reduction. The findings have important implications for policymakers, organizations, and Islamic philanthropists involved in poverty reduction efforts. Policymakers can promote and support waqf practices to mitigate poverty, while organizations can focus on initiatives that improve family well-being. The study highlights the importance of family well-being in poverty reduction efforts and provides valuable insights for poverty reduction strategies and initiatives

Effect of aqueous extract of olive (Olea europaea) fruit on lipid profile in female rabbits

The activity of the aqueous extract of Olea europaea was tested at concentrations of 8, 15 or 20 mg/kg of body weight on lipid profile in twenty female local rabbits. These animals were randomly divided into four groups (five animals in each group). Three groups were dosed orally with the concentrations mentioned above, while the last was administered with distilled water and considered as a control group. These animals were orally dosed by aqueous extract using a micropipette for 30 days. The results showed that there was a significant (

DETERMINANTS OF MIDDLE CLASS SCHOOL DROPOUT AMONG BOYS IN THE RIYADH PROVINCE OF SAUDI ARABIA

Purposes: This study examines the determinants of middle-income school dropouts in Saudi Arabia. The determinants of dropouts are fairly similar across many countries worldwide and this has made the issue of dropouts a global phenomenon. However, the situation in Gulf countries is different because these countries accord special treatment to male children but not to female children. This directly affects the educational pursuit of male children in the region. Saudi Arabia was empirically studied and a sample of 360 respondents was investigated. The respondents were drawn randomly from each of the 11 secondary night schools. Methodology: The method used for analysis in this study was a combination of descriptive statistics involving cross-tabulations and simple multivariate logistic regression. The results showed that the majority of the dropouts are aged between 15 and 32 years. Results: The regression results showed that absenteeism, educational targets, and value have a significant relationship with school completion. These results may be connected to the findings of the Dubai School of Government in 2011, which indicated that male pursuit of employment opportunities was of greater significance in achieving social and economic mobility compared to educational achievement. This suggests that Saudi males prioritize employment opportunities over educational achievements. Implications/Applications: On the other hand, there are also those who place value on education and will make the effort to complete their school education in Saudi Arabia. Novelty/Originality: Thos finding reveals a significant correlation between school completion and educational value. The implication is that male student who values education are more likely to complete school in comparison with those who do not value education. Efforts must be intensified to promote retention and create awareness among the young people of the benefits of education in the long run
