Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

urban centers are in continuous development due to different circumstances from the past till now, and sometimes due to the needs or for a specific reason enormous changes have been occurred. When changes occurred in the transportation means and cities expanded some of the major changes were developing of new areas and new axis. The research aims to identify the role of morphological changes and their mechanism and how they impact on the changes of the structure of the city however there is lack of clear vision about the mechanism of how change in land uses in the traditional area that consequently affects the changes of urban structure. The research is based on the hypothesis that states; the structural characteristics of the traditional center of Sulaimani city as one of a major city in Kurdistan region on Iraq (KRI) including the space organization has been to change the effect of the morphological changes represented by changing of land uses from residential form to commercial or services area, The city of Sulaimani was chosen for the case study since it is regarded as a model for the urban structure that testified structural changes at a partial and a whole level. The space syntax methodology has been adopted for the identification and characterization of space organization properties and changing in city structure, the case study area has been studied during three different periods of time to analyses the changes that has been occurred in the area. Finally, the study found the effect of changes in the morphology, which is clearly obvious according to the distinctive changes happened in the area was reflecting the structural system
Experimental investigations of solar desalination unit based on humidification and dehumidification processes are presented in this work. The test rig is designed, constructed, and tested. The experiments were tested at Baghdad University, college of engineering, Mechanical engineering department (33.3° latitude north, 44.36° Longitude East). The effects of Linear Fresnel Lenses have been studied in this work. Different cases are investigated such that: they were placed on the 3rd and 4th absorbers of the PTC, they were placed on the humidifier chamber and they were placed on the 2nd and 3rd absorbers of the PTC. when lenses were placed on the humidifier to concentrate solar energy on the transparent glass cover the absorber surface temperature was increased by 8.2 % at 14:00 pm, the inlet temperature of the oil was increased by 7.1 % while the outlet oil temperature was increased by 14 % and water production is increased as (31.2 %) at 14:00 pm is higher than that when these lenses were placed on absorbers
