ABSTRACT

The architectural studies in general dealt with the study of several concepts that have an important role in the design part as well as providing preparation and support of its requirements, procedures, and rules for a variety of aspects and details. The current research directed towards a specified study of the relationship of two influential concepts within the frame-work of architectural design. These concepts are; the method and its relationship to the state of intellectual repercussion with the necessity of introducing, clarifying and defining the general knowledge frameworks for the nature of those rela-tions and the effect of the indicators of that situation with respect to the general knowledge about them.
This research is Directed to define the general frameworks of the basic research concepts, which are both the method and the repercussion with other concepts that are influential, design, thought or thinking, to determine the cases of interconnec-tion between them and then to refer these cases to several levels, and to propose the models adopted from the studies and architectural proposals, which will determine the indicators needed to define the situation The correlation between the basic concepts of research (method and repercussion) within the framework of the field of architecture to show that the final out-come refers to the adoption of the repercussion as an instrument or preparation for the benefit of the method within the ar-chitectural design

Keywords: Method, design, idea, thinking, repercussion.

ABSTRACT

The research deals with the concept of architectural knowledge as one of the influences in the process of architectural design, as the nature of the designer and trends in the lure of knowledge derived from the reality of society through successive historical periods have the greatest impact on his ideas, and the nature of the output achieved requires that the architecture exceeds the local boundaries to the site boundaries. It is reflected in its results, thus determining the research problem in (The insufficient knowledge perception available about the architectural product between the duality of knowledge and knowledge thereof). The goal of research to clarify the mechanisms of knowledge of architectural production as well as their character-istics and dimensions. Accordingly, the research assumes that their indicators have a positive impact on the formulation of architectural output. In order to address the research issue and achieve the objectives of the research and verify its hypothesis, a knowledge framework was first constructed, then a comprehensive theoretical framework was extracted from the architec-tural and supporting propositions to be finalized in three main indicators, namely: “Mechanisms of knowledge of architectural production, characteristics of architectural knowledge of production, and dimensions of architectural knowledge. Finally, a number of conclusions have been reached which provided that the knowledge of architecture as a product is linked to the three knowledge “Galali, Aesthetic, and Kemalism”, as well as a correlation between Cognitive characteristics of the archi-tectural product of the port and its dimensions, as it was associated with absorption of production through the cash situation dealt with by man shall his reign began on what is watching from the output characteristics of the port structure with a reflective surface to remove him deep knowledge inherent in the structure.

ABSTRACT

The Major sources of water are surface and subsurface. Surface water includes Rivers, Reservoirs, Creek, Streams, etc. This paper deals with using a neural network model to recognize dissolved oxygen in Shatt Al-Arab. Within the present study, Shatt Al-Arab River (Basrah-Iraq) is considered as the study area with monthly observed data from 2009-2014. Artificial Neural Network (ANN) has been applied to pattern the relations among eight (8) water quality parameters which are devoted for predicting one parameter (1) so that to decrease the load of long experimental procedure. Physical and chemical parameters that are inserted in the model are:   pH, total dissolved solids, electrical conductivity, sulphate, phosphate, calcium, magnesium and nitrate. Dissolved oxygen (DO) is included in the output models. The three layered feed-forward model with back-propagation multi-layer perception (MLP) models architecture of 8-8-1 for DO. The artificial neural network has got training successfully and has been tested with 70{1524fc3db9b9185e4da51c194ca3b05c06ae483421403c447a0666442f370a52} and 30{1524fc3db9b9185e4da51c194ca3b05c06ae483421403c447a0666442f370a52} of the data groups. Statistical criteria of correlation coefficient (R²) and mean square error (MSE) are used to evaluate performance of the models. The correlation coefficients of the artificial neural network model for predicting DO have been 0.99354 and 0.98237, and mean square error for the model are 0.007698 and 0.00122 respectively. It can be concluding that these techniques provide similar accuracy in estimating DO concentration and predicting the dissolved oxygen (DO) in Shatt Al-Arab

ABSTRACT

The importance of affordable housing has emerged recently due to the suffering of most urban areas and developing countries in particular from the high rates of population growth and migration to cities, in addition to the conditions of poverty and war, which led to the loss of many families for their housing units. (The need for a comprehensive knowledge framework clarifying the concept of affordable housing, choosing the best housing type and cost reduction factors (facilitation aspects) at the local level in light of the country’s urgent need for affordable housing.) Accordingly, the objective of the research was to: (Provide a comprehensive knowledge framework that clarifies the concept of affordable housing and choose the best housing type and cost reduction factors (facilitation aspects) in accordance with local privacy).

The research hypothesis : (The factors and means of reducing housing costs (aspects of facilitation mentioned in the research) at the two levels (housing complex and housing unit) as well as choosing the housing style (vertical or horizontal) a role in achieving the principle of affordable housing and solving a large part of the housing crisis.

For the purpose of solving this problem, three phases were identified, including the construction of a theoretical framework, which included (4) vocabularies (characteristics of affordable housing, cost-raising factors, cost reduction factors, and dimensions of affordable housing). This is followed by the application of these vocabulary by electing two local samples. The extent of facilitation and comparability between them. The results showed that the vertical building pattern (residential buildings) is characterized by its lack of large areas of residential land, thus it is characterized by being less expensive than horizontal construction. This does not prevent investors from building high-quality residential towers targeting the rich.

Keywords: Affordable Housing – Better Housing – Cost Reduction

ABSTRACT

The physical environment of Al-Hilla city is subject to successive developments due to changes in various economic, technological and humanitarian aspects.

These changes are accompanied by the physical appearance of the phenomenon of “visual pollution”, which results from the imbalance in the visual performance of the components of the physical environment of the city, causing the sense of psychological discomfort and loss of belonging to the surrounding environment and its aesthetic is almost nonexistent.

The objective of this research is to evaluate the state of the visual components of the physical environment of Al-Hilla city, through an analytical field study of the visual impact indicators of the state of the physical environment of Al-Hilla city, and comparing it with the visual performance standards, to determine the defect and gap. For research purposes, the field study was conducted for the most important street in the city center, which is Imam Ali Street, on the basis of which the visual pollution ranges were determined, and therefore the recommendation of making the right decisions (whether at the level of implementation or field monitoring) is necessary in order to reduce or mitigate the phenomenon of visual pollution) to improve the visual performance of the street in particular, and the physical environment of Hilla city in general.

ABSTRACT

The present work is about an organized crime which is considered a serious phenomenon that generally comes upon the world and especially in the Iraqi area. In recent decades, Al- Hilla City has suffered from spread variety of crimes, which lead the citizens to lack the sense of security. For this reason, it is seen it is significant to study this phenomenon with a new parallel phenomenon which causes their appearance. In addition, it is thought that this topic has not been tackled yet. The problem of the study lies in the lack of holistic scientific knowledge about the role of the synthetic properties of spatial organization for the city of Al- Hilla in crime growing. The study aims at establishing a holistic knowledge of that role. To deal with the problem of the research, an inductive approach (descriptive- analytical) has been adopted. The data is got from the responsible security institutions and is analyzed through invest the calculation method (space syntax).

The results of the research showed that there are four areas ((4 zones) where crime is concentrated in the city and the growth of crime is related to the change of the synthetic characteristics of spatial organization (Connectivity, control, and Integration) of urban space. On the other hand, the diversity of crime in urban areas is related to other parallel phenomena and not to the structural characteristics of urban space.

ABSTRACT

The simultaneous removal of copper and cadmium from a simulated wastewater using rotating tubular packed bed of woven screens electrode was investigated. The effect of weight present of each metal on the removal efficiency and current efficiency was studied. The experiments were carried out at current 1.5 A, rotation speed 450 rpm, pH=2, and total concentration of metals (300 ppm) at different weight percent of each metal. The results showed that the removal efficiency of copper increased from 93.5 % to 99.33% as its weight percent increased from 20% to100%. In a similar fashion, the removal efficiency of cadmium increased from 80% to 90% as its weight percent increased from 20% to100 %. The results confirmed that the removal efficiency of any metals decreased in the presence of other metal. The results established that current efficiency for the simultaneous removal of copper and cadmium decreased with increasing of electrolysis time and Cd percent weight or decreasing of Cu weight percent. Current efficiency is higher at the initial stage of electrolysis and then declined with increasing time for all weight percent of metals.

ABSTRACT

A nanoantenna is designed to transform high frequency into energy. The proposed antenna is made of aluminum. are shaped with a pair of nanoparticles brought in close nearness. Antennas separated by small gap sprinted on a Si layer, which is designed as a flat-edge bowtie, with a ground plane at the under most of the substrate with a feeding putting in the gap of the bowtie antenna. The proposed antenna is designed using 3D￾electromagnetic solver (CST) programs and analyzed for the optimization of metal thickness, gap size, and geometrical length. Simulations are conducted to investigate the behavior of the nanoantenna illuminated by the linearly polarized plane wave. The nanoantenna parameters such as substrate
thickness, feeding size, feeding type, and feeding material were changed to select the most efficient nanoantenna with a large directivity in our reaserch find the nanoantenna make a high electric field enhancement in their gap region. This specialty can be employed for SERS or bioventing to improve
the detection limit and measure the presence of single molecules. For this, it is necessary to create antennas with enough small gaps, to be capable to recompense for the defects created during the fabrication process and reach antenna characteristics that are close to the ones presage by simulations.
The numerical simulations are studied to improve the best E-field of the antenna within the 250–700 THz frequency range. The proposed antenna offers multiple-resonance frequencies and good return loss in the frequency band of 310 THz, as well as an output electric field of 5.48 v/m to 7.8 v/m. Upon changing the type of feeding in the gap (without feeding, air feeding, dielectric silicon, or feeding),and we find that when using the air between the gap, the S-parameter is (-12.9) dB at the resonance frequency of (531.3) THz
and the directivity is 7.41 dB at 666 THz incident frequency.
