The Research deals with the negative phenomena which appeared in the urban scenes of the Iraqi cities after 2003, particularly trespassing the architectural design of the urban Individual houses. Many academic researchers , critics, and cultural circles, drawn attention to the impact of political and cultural variable change on such phenomena without detailed analysis . The research problem is set according to central questions : If the phenomena is the trespass , what
are the sides which are being trespassed in the division of the individual house? , If the diagnosis of the phenomena denotes perceived repetition of the cases , So what's size of this transposes on the architectural design of the individual house? , and what are its connections socially and economically ? The research problem diagnosis by: The lack of knowledge about the impact of the phenomena of trespassing on the architectural design of the individual house specifically?.
The research target is to explain the range of the spreading of trespass in these houses with objective , social , economical investigation, Then clarify the phenomena's impact on the architectural design of individual house in Baghdad. The theoretical frame is built to extract the research indicators ( economic, social and design) theoretically , then enhance them with the study of the development of the urban house in Baghdad along the 20th century. The indicators were applied on (12) samples were distributed on (2) residential districts, (Palestine Street, AL- Sadr City) which they are various in the residential areas
and they different in the social and economic level of the their dwelling, and their houses have modifications and divisions, then find its impact on the designing level of the individual house in Baghdad after 2003. The results showed that both districts in Baghdad houses have this kind of illegal division and (non.efficient , non functional relationship and some of them non ventilation) , the spread of the phenomenon reflects that there are special details in the methods of division and the modification of the houses ,That should be a widely reviewed to get to limit this Regulations in precedent phenomena and regain the residential cultural of the city.
In this research, deposition of titanium oxide (TiO2) and vanadium oxide (V2O5) thin film in different mixing percentage (0, 25 ,50, 75 and100)% on the substrate of glass .The coating thickness was ( 50 nm ).
In this research contact angle was measured and the effect of weather conditions. Results showed that the value of the contact angle of the prepared films reached its highest value at 50% (TiO2+V2O5) was 160º.
The results showed that the optical transmittance of TiO2 and V2O5 thin film decrease with increasing the deposition angle and decrease with increasing V2O5 pro

As one type of heating furnaces, the electric heating furnace (EHF) typically suffers from time delay, non-linearity, time-varying parameters, system uncertainties, and harsh en-vironment of the furnace, which significantly deteriorate the temperature control process of the EHF system. In order to achieve accurate and robust temperature tracking performance, an integration of robust state feedback control (RSFC) and a novel sliding mode-based disturbance observer (SMDO) is proposed in this paper, where modeling errors and external disturbances are lumped as a lumped disturbance. To describe the characteristics of the EHF, by using convection laws, an integrated dynamic model is established and identified as an uncertain nonlinear second ord

The Gas Assisted Gravity Drainage (GAGD) process has become one of the most important processes to enhance oil recovery in both secondary and tertiary recovery stages and through immiscible and miscible modes. Its advantages came from the ability to provide gravity-stable oil displacement for improving oil recovery, when compared with conventional gas injection methods such as Continuous Gas Injection (CGI) and Water – Alternative Gas (WAG). Vertical injectors for CO2 gas were placed at the top of the reservoir to form a gas cap which drives the oil towards the horizontal oil producing wells which are located above the oil-water-contact. The GAGD process was developed and tested in vertical wells to increase oil r

The main objective of this paper is to study the behavior of Non-Prismatic Reinforced Concrete (NPRC) beams with and without rectangular openings either when exposed to fire or not. The experimental program involves casting and testing 9 NPRC beams divided into 3 main groups. These groups were categorized according to heating temperature (ambient temperature, 400°C, and 700°C), with each group containing 3 NPRC beams (solid beams and beams with 6 and 8 trapezoidal openings). For beams with similar geometry, increasing the burning temperature results in their deterioration as reflected in their increasing mid-span deflection throughout the fire exposure period and their residual deflection after cooling. Meanwhile, the existing ope

This paper presents an experimental study of cooling photovoltaic (PV) panels using evaporative cooling. Underground (geothermal energy) water used to extract heat from it during cooling and cleaning of PV panels. An experimental test rig was constructed and tested under hot and dusty climate conditions in Baghdad. An active cooling system was used with auxiliary an underground water tank to provide cold water as a coolant over both PV surfaces to reduce its temperature. The cellulose pad has been arranged on the back surface and sprays cooling on the front side. Two identical PV panels modules used: without cooling and evaporative water cooling. The experiments are comprised of four cases: Case (I): backside cooling, Ca
