The late twentieth century saw clear sophisticated in information and multimedia technology, which
becoming a bigger influential in daily human life and also in the built environment posed by the need and
shape, so architecture Included all achievements that were produced by this technology, that’s current
research focus, Thus the emergence of the research problem of the "absence of a clear vision about the
nature of the relationship formulated by the media as the media surfaces of architecture with the receiver".
The goal of research Represent with trying to define what the media and media architecture clarify new
relationship with the receiver drafted by the type of sensory and behavioral impact through the formulation
of the surfaces of architecture. To achieve the objective search mode method of literature review of previous
dealt to define multimedia architecture such as offering in Search explains the meaning of a new type of
architecture witnessed by the architectural arena specific dimensions and goals, To move in the private
segment to illustrate the specificity and tools design represented-media and smart materials responsive

This work, presentsnanofluids as a new coolant technology in automobile engines compared with other conventional coolants (Ethylene glycol/water(antifreeze), distilled water) experimentally.The increase in thermal conductivity of the base fluid (water) by adding nanoparticles in certain ratios led to more absorption of heat from engine block. The experimental results indicated that the drooping in exit engine coolant temperatures was about(18.5%) by using (0.3%TiO2/water)nanofluid, and about (9%) by using distilled water comparative with Ethylene glycol/water(50/50) at the test end. The increasing in radiator(heat exchanger) effectiveness was about (51%) with using nanofluid, and about (29%) with using distilled water comparative with Ethylene glycol/water(50/50) at the test end. The results indicated also that the increasing in Nusselt’s number at entrance of radiator hose was about (42.8%) with usingnanofluid and about (30.5%) with using distilled water compared with Ethylene glycol/water(50/50).This led to increase convection heat transfer coefficient at entrance of radiator hoseby about (65%) with using nanofluidand about (49.5%) with using distilled water compared with Ethylene glycol/water (50/50).

In the present work, experimental study has been done to estimate the performance of solar heating system by air-water (Dual) solar collector. Flat plate dual solar collector with dimensions (120 cm length, 80 cm width and 15 cm thickness) has been used for heating the test space with dimensions (2×2×2.5) m. In this study, the system has been operated in Al-Najaf city with 45o tilt angle to the south. The results obtained that the dual flat plate solar collector daily efficiency is 52.02 %.They also showed the ability to use dual solar collector absorber as heat exchanger in the night to maintain room temperature in the comfort condition for space heating in the winter season.

Experimental investigation of film cooling from two staggered rows holes,backward and forward; of opposite injection angles has been done. The forward holes row was embedded in arc trench. The aim of using arc trench is to enhance the poor mechanical properties of that in rectangular trench. The results of film cooling performance are given here in a form of adiabatic cooling film effectiveness and heat
transfer coefficients. In the tests test warm air is blown through tunnel, and cold air through the plenum chamber. When the warm air flowed through the test section it heated the model downstream. Infrared camera is used to measure the model surface temperatures. The comparison with the same holes arrangements and same holes and trench dimensions between existing rectangular trench results and present arc trenched
showed that the film cooling thermal performance for both cases are approximately very close with slight differences, these differences are more or less according to the values of blowing ratios.

The study is perhaps the first to evaluate and establish the relationship between
Quality, benchmarking, Reliability and globalization in industrial engineering activity
in Emirates, where the study was conducted on international companies operating in
Dubai. The study seeks to understand the impact & effect of globalization on all the
various topic of industrial engineering that distinguish implementing quality
management program, reliability program and ISO certified and benchmarking
companies from none implemented benchmarking or quality, reliability, ISO program.
Also the study tries to evaluate the effect of these factors on the organizational
performance. The study found a number of significant relationships between the
reliability, and globalization in industrial engineering activity. It also found support for
the argument that high reliability, high quality and benchmarking practices will
improve industrial engineering and at the end result will improve overall organizational
performance in large, medium and small global businesses. Therefore the results
achieve the goals of industrial engineering to eliminate wastes of time, cost, materials,
energy, and other resources to increase profits.
