the main goal of the present study is to identify characteristics of the inter-station horizontal magnetic responses and the vertical magnetic data, as two types of magnetotelluric transfer functions, in the modeling procedure. through consideration of model responses and two-dimensional inversion of synthetic data, sensitivity of the data components in detecting different geophysical structure...

earthquakes could have catastrophic impacts on tunnels and buried structures. liquefaction phenomenon is one of the most destructive effects of earthquakes. liquefaction results in decreasing effective stress and this consequently leads to decreases in shear strength of the soil. as a result, large deformation in both soil and buried structure occurs. moreover, liquefaction causes soil boiling,...

this paper presents developing an analytical model for flux switching motors. the motor is a class of variable reluctance motors that has two windings on stator; a field winding and an armature winding. due to saliency of both stator and rotor poles, accurate modeling is difficult which arises from the nonlinear behavior of the machine. this paper presents a simple model which is able to predic...

The cultural heritage preservation requires that objects persist throughout time to continue to communicate an intended meaning. Digital technology and specifically 3D digital technology is naturally a critical component in preservation. Yet once in the digital world the object's persistence is inextricably linked to data persistence and current 3D technologies do little more than capture a sil...

Convective heat transfer and entropy generation in a 3D closed cavity, equipped with adiabatic-driven baffle and filled with CNT (carbon nanotube)-water nanofluid, are numerically investigated for a range of Rayleigh numbers from 103 to 105. This research is conducted for three configurations; fixed baffle (V = 0), rotating baffle clockwise (V+) and rotating baffle counterclockwise (V−) and a r...

Business process performance evaluation is a key step towards assessing and improving e-business operations. In real-scale scenarios, such evaluation requires the collection, aggregation and processing of vast amounts of data, in particular audit trails. This paper aims at enabling such evaluation by integrating workflow technology with data warehousing. We first present a data model for captur...

During the past decade, data warehousing has been widely adopted in the business community. It provides multidimensional analyses on cumulated historical business data for helping contemporary administrative decision-making. Nevertheless, it is believed that only about 20% information can be extracted from data warehouses concerning numeric data only, the other 80% information is hidden in non-...
