Template-generated Web pages contain most of structured data on the Web. Clustering these pages according to their template structure is an important problem in wrapper-based structured data extraction systems. These systems extract structured data using wrappers that must be matched to only particular template pages. Selecting single type of template from all crawled Web pages is a time consum...

Robotic contact-rich insertion tasks present a significant challenge for motion planning due to the complex force interaction between robots and objects. Although many learning-based methods have shown success in contact tasks, most need sampling or exploring gather sufficient experimental data. However, it is both time-consuming expensive conduct real-world experiments repeatedly. On other han...

A dynamometer is used to determine the electromechanical characteristics of electrical machines. So dynamometers are used to optimize the producing process of electromotor. Dynamometers are equipped with variety of systems which are so expensive and need some mechanical equipment to couple with motors. Furthermore using of these mechanical couplings is a time consuming process. In this paper a ...

Tissue phenotyping of the tumor microenvironment has a decisive role in digital profiling intra-tumor heterogeneity, epigenetics, and progression cancer. Most existing methods for tissue often rely on time-consuming error-prone manual procedures. Recently, with advent advanced technologies, these procedures have been automated using artificial intelligence techniques. In this paper, novel deep ...

Optimization using radial basis functions as an interpolation tool in trust-region (ORBIT), is a derivative-free framework based on fully linear models to solve unconstrained local optimization, especially when the function evaluations are computationally expensive. This algorithm stores the interpolation points and function values to using at subsequent iterations. Despite the comparatively ad...

Nowadays, for managing coastal zones and littoral lands, we need accurate and updated information on hydrography of coastal areas. These data can be obtained by local measurements, airborne imagery and satellite data. Using satellite data is not time-consuming and expensive like than other methods, thus it is most economical method in the world. Unfortunately, this method is not developed in Ir...

Traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. Facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. To design a membrane process for olefin-paraffin separation, equilibriu...

Oil production optimization is one of the main targets of reservoir management. Smart well technology gives the ability of real time oil production optimization. Although this technology has many advantages; optimum adjustment or sizing of corresponding valves is still an issue to be solved. In this research, optimum port sizing of inflow control devices (ICDs) which are passive control valves ...

We describe an implementation technique for boundary element methods that greatly reduces the required number of evaluations of the Green’s function. Assuming that evaluating the Green’s function is a costly operation, our approach has a computational cost that is almost independent of the chosen discretization scheme. Nyström methods, collocation methods and Galerkin methods lead to similar co...

Metamodel-based design is a well-established method for providing fast and accurate approximations of expensive computer models to enable faster optimization and rapid design space exploration. Traditionally, a metamodel is developed by fitting a surface to a set of training points that are generated with an expensive computer model or simulation. A requirement of this process is that the funct...
