today, we see that despite the plans and decisions made about the historical fabric, the people are very faintly seen and conservation the historic fabric of urban is one of the main concerns management urban in the absence of efficient management and lack of attention to the needs of local people, the historical fabric urban is destroyed. in this article are examined ways other than physical m...

Software companies exploit data about completed projects to estimate the development effort required for new projects. Software size is one of the most important information used to this end. However, different methods for sizing software exist and companies may require to migrate to a new method at a certain point. In this case, in order to exploit historical data they need to resize the past ...

In the dynamic software field there are major challenges in adapting metrics and cost estimation methods to continuing changes. There is a need to assess emerging trends and re-interpret software size measures and estimation models for new processes. Future trends of software systems are overviewed with implications for software sizing and cost estimation capabilities. Methods are shown to hand...

In this study, carbon fiber (CF)/polyamide 6 (PA 6) fabric laminates molded by in-situ polymerization using ε-caprolactam were evaluated. To investigate the effect of CF sizing agent on their molecular weight distributions PA in CF/PA and mechanical properties, we removed a surface heat treatment before molding. The concentrations monomer oligomer (carbon reinforced thermoplastics (CFRTP)) appl...

The additives and contaminants which occur in textile fibers vary widely, depending on the type of fiber and the pretreatment which it has received. Synthetic fibers such as nylon and polyester contain trace amounts of contaminants such as catalysts and catalyst deactivators which remain after the synthesis of the basic polymers. In addition, there are frequently a number of materials which are...

The fibre-matrix interfacial properties of glass-fibre/polyamide-6 (GF/PA-6) composites produced by thermoplastic resin transfer moulding (TP-RTM) were investigated. Two different fibre sizings compared, a specially-developed novel reactive sizing and standard silane glass sizing. Scanning electron microscopy, atomic force microscopy number mass-loss techniques employed to study the form, distr...

regarding the importance sizing and grading crop in the market and other processing operations, in this study, a machine for hazelnut sizing designed, constructed and evaluated. the machine based on sizing mechanism of diverged belt. the sizing unit has a structure similar to a horizontal belt conveyor. the distance between the ropes at the entrance of the product (the end of the driven roller)...

Infrared thermography is a well-known non-destructive testing technique for detecting defects in unidirectional fiber reinforced polymer laminates. When applied to woven fabric polymers, however, the weave structure causes strong disturbances and patterns background of thermal images, making accurate reliable defect assessment challenging task. In this paper, concept k-space filtering introduce...
