In this paper, we study query processing in a distributed text database. The novelty is a real distributed architecture implementation that offers concurrent query service. The distributed system adopts a network of workstations model and the client-server paradigm. The document collection is indexed with an inverted file. We adopt two distinct strategies of index partitioning in the distribute...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
فرایند خسارت دیدن یک عضو، طبقه ای از سازه و یا کل آنرا می توان با یک عدد بین صفر و یک مرتبط نمود. آن عدد نشانه خسارت (damage index) نامیده می شود.شاخص های خسارت ممکن بصورت محلی (فقط برای یک عضو) یا کلی (برای کل سازه ) تعریف شوند. اکثر شاخص های محلی خسارت طبیعتا تجمعی می باشند که وابستگی خسارت به دامنه و تعداد نوسان های بارگذاری را منعکس می کنند. شاخص های خسارت می توانند در برنامه ریزی بلیا بر...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
Understanding the wave pattern as a first step in marine studies is very important. The global models as a source of data can be used to simulate local waves. Before applying them, their results should be evaluated. One of the most important global models is the ECMWF model. Based on the wave simulation in the northern coast of the Persian Gulf, it can be said that the ECMWF model results are o...
bibliometric, and scientometric approaches are used to provide appropriate tools for evaluating scientific products at local, national, and international levels. iran, the same as other countries, has many universities and research centers in the field of engineering that iran's most of the scientific products account for the field of engineering. this study is a descriptive approach using scie...
