refraction and diffraction combination of waves, is very important and applicable problem in coastal engineering (e.g. for designing break - water). however, formulation of this phenomen and numerical solution is very difficult. in this study, a numerical algorithm based on the mild slop sea bed theory is presented to obtain the appropriate governing equations of combined refraction diffraction...

forest harvesting operations for extracting of forest products in these trails, causing extensive damage in a wide range of soil and its productivity every year, therefore it is necessary to research about degradation of soil properties should be down. the aim of this study was investigate changes in the skid trails soil physical characteristics due to wheeled cable skidder traffic by measuring...

The potable water declined after the global climate crisis. Due to warming. River levels have also decreased. Moreover, so much has become dependent on from wells. Which are often salty. Purifying this requires many fossil fuels that cause damage environment. Therefore, researchers turned renewable energy sources, including solar energy. In paper, we designed and made a distiller, single sink w...

Objectives: To improve the efficiency of tri-level segmentation tasks for handwritten Gujarati text. Methods: Using hybrid methods segmentation, we have used line, word and character from image. This study presents a paradigm that works with touching characters, slop line written on page, overlapping, etc. It evaluated dataset 500+ images created by us different writing sentences people. We Hor...

Given the importance of cross-disciplinary research (CDR), facilitating CDR effectiveness is a priority for many institutions and funding agencies. There are a number of CDR types, however, and the effectiveness of facilitation efforts will require sensitivity to that diversity. This article presents a method characterizing a spectrum of CDR designed to inform facilitation efforts that relies o...

As a country which frequently suffers from natural disasters, especially earthquakes, China has implemented its own disaster management system to respond to them. The Chinese government gained practical experiences on how to respond to severe earthquakes after the 2008 Wenchuan Earthquake and 2010 Yushu Earthquake. Although China has done a lot to improve its response operations, challenges rem...
