There are many reasons for high level ATPG, but the major one is the need for ATPG to be done at the same level as design. Today a designer has to drop down to gate level to run an ATPG, while verification and most other design activities can be done in RTL. At one time software debugging tools worked at the assembler level, today they work at the level at which people write. Our ATPG tools sho...
Abstract The population growth, the development of cities, industry, agriculture, and improper use of resources especially non-renewable resources have led human beings to face the danger of running out of resources. In some cases, in addition to the above, irreversible environmental and geological hazards have occurred due to the overdrawn of resources. Over extraction of groundwater resourc...
accurate groundwater level modeling and forecasting contribute to civil projects, land use, citys planning and water resources management. combined wavelet-artificial neural network (wann) model has been widely used in recent years to forecast hydrological and hydrogeological phenomena. this study investigates the sensitivity of the pre-processing to the wavelet type and decomposition level in ...
In this study, the relationship between land use and land cover change (LUCC) and variation of groundwater table and quality in the SanGong Oasis Region in the western China is investigated using a geospatial approach. Specifically, the interactions among groundwater, surface water, and LUCC are analyzed through the utilization of geographical information system (GIS), remote sensing (RS) image...
Utilization of wastes from livestock complexes for irrigation involves the danger of groundwater pollution by nitrates. In order to prevent and minimize pollution, it is necessary to apply geological-hydrogeological evidence and concepts to the situation of wastewater irrigation for the purposes of studying natural groundwater protectiveness and predicting changes in groundwater quality as a re...
Introduction The increase in population and need for food has resulted in the development of agricultural lands and pressure on aquifers, which has led to a sharp decline in the quantity and quality of groundwater resources. In many countries, especially in arid and semi-arid regions, in which the average annual precipitation is not adequate to support water requirements, groundwater is common...
Irrigated row-crop agriculture is contributing to declining groundwater in areas such as the Mississippi Delta region of eastern Arkansas. There is a need to move toward sustainable levels of groundwater withdrawal. Recent improvements in remote monitoring technologies such as wireless soil moisture sensors and unmanned aerial vehicles offer the potential for farmers to effectively practice sit...
in this paper, we present an application of evolved neural networks using a real coded genetic algorithm for simulations of monthly groundwater levels in a coastal aquifer located in the shabestar plain, iran. after initializing the model with groundwater elevations observed at a given time, the developed hybrid genetic algorithm-back propagation (ga-bp) should be able to reproduce groundwater ...
It has been well-accepted that peritoneal dialysis (PD) is an effective modality for end-stage kidney disease (ESKD). However, PD drop-out important challenge technique failure in a program. Therefore, it of utmost importance to address the reasons unit. The aim this study determine causes adult patients at our center.
Global sea level has been rising over the past half century, according to tide-gauge data1,2. Thermal expansion of oceans, melting of glaciers and loss of the ice masses in Greenland and Antarctica are commonly considered as the largest contributors, but these contributions do not entirely explain the observed sea-level rise1. Changes in terrestrial water storage are also likely to affect sea l...
