The Railway track is the main factor in evaluation any railway system, because it has direct effect on speed, comfort and safety of Train. As it costs about 35% of total construction of new railway, this research is important to study all elements and use available data to evaluate the studied line, and then it analyses the results to clarify the reaction between the defects. Therefore, the paper shows the priority of maintenance with less prices.
Many constructionl systems were used in the construction of airports. These systems vary according to the development of the various aircraft models as well as to the increasing number of passengers. This study will include a review of some airpor ts buildings, which had been built depending on the metal construction technique that achieved larger architectural dimensions and spaces for passenger terminal in terms of shape and function. This research includes a study of the evolution of the metal technique used in airport construction especially for passenger terminal showing its effect in realizing the architectural space including its dimensions and spaces and in meeting the functional requirements inside it particularly securing passengers safety, comfort, and the ease of controlling their movement to the taking off places, as well as securing ventilation and natural lighting of the building.

The overlay functions in Geographic Information Systems (GIS) are considered as one of the basic functions of these systems, and often, a variety of data stored in layers may be integrated together to generate new layers that contain useful informati on for decision-makers. All geographic objects are stored in layers and usually rely on crisp set theory, whether, stored in a vector or raster format. In many cases, boundaries of classes or objects are not clearly defined, or when we perform classification of features into classes, the geographic objects located in the boundaries of classes could be classified into the wrong class. This research aims to develop overlay functions methodology based on fuzzy logic, reclassify the objects into fuzzy classes, and study the usability of this method to integrate data of specific phenomenon to help make optimal decisions. To implement and examine this idea, a set of Fuzzy Membership Functions was developed using the Python programming language embedded within the ArcGIS environment. Through this Fuzzy Membership Functions, the user can generate fuzzy sets and combine with each other according to one of fuzzy operations, and thus the generation of fuzzy sets allows supporting the right and reliable decision. To test the proposed fuzzy model capabilities, it has been applied in Tartous governorate to select suitable tourist facility sites in accordance with groups of factors. In summary, data integration using proposed fuzzy overlay functions can improve the reliability of data representation and thus the reliability of make the best decisions.
The research aimed at estimating the optimum size of autumn potato farms in Al-Qusir district-Homs province. A simple randomized sample of 192 farmers has been taken from five different villages. The sampled farms were divided into four classes b ased on size. The results showed that the production, return, net return and the net profit of 1 SYP/ Donnum were increased along with size of the farm .By using one way Anova, The analysis showed that there were statistically significant differences among the size of farms based on the above-mentioned measures.
