With long-term evolution of large scale software systems, the study and engineering of architectural evolution becomes more and more important. In order to manage high level changes, the architects should plan the architecture evolution in a series of releases. Planning and analysis of architectural evolution is a challenge and plays a significant role in evolution management. An assessment solution could promote overall accuracy and quality of the evolution process. Compliance checking with expert-defined rules is a well-known assessment solution and could be applied in the field of architectural evolution. In this thesis, a solution is proposed in order to compliance check these evolution... 

In this study, the problem of pricing and inventory control for non-instantaneous deteriorating items with two separate warehouses is considered. One warehouse is owned and the other one is rented. The rented one has a higher holding cost due to better preserving facilities. In the literature, a common assumption is that the deterioration of items starts at the instant of their arrival, while in fact the majority of goods have a short time span for maintaining quality or original condition, during which no deterioration occurs. For non-instantaneous deteriorating items, the common assumptions may lead to the overvaluation of the total annual relevant inventory cost. In the present study a... 

Artificial recharge is an effective method of enhancing groundwater resources. Different methods are being used for aquifer recharge, including direct surface and subsurface method, Combined and indirect methods. Among these, direct surface methods such as flood spreading and ditch and furrow techniques are most commonly used methods. They are frequently used in Iran too, but what is disregarded herein, is the application of modern methods of artificial recharge such as ASR and ASTR. ASR and ASTR are methods of artificial recharge through injection wells/borings, in order to recharge deep-seated or those aquifers which are separated by impermeable stratum from the surface. These methods,...
