one of the most remarkable basis of the gravity data inversion is the recognition of sharp boundaries between an ore body and its host rocks during the interpretation step. therefore, in this work, it is attempted to develop an inversion approach to determine a 3d density distribution that produces a given gravity anomaly. the subsurface model consists of a 3d rectangular prisms of known sizes ...
The Latin American School of Human and Medical Genetics (ELAG) is the main course of its kind in the genetics field in Latin America. Here we describe the main challenges regarding the organization of such event, including how we obtain funding and how we proceed with student selection. Thus, we aim to share our experience with other groups that intend to follow this format to create similar ev...
abstract evapotranspiration (et) determination is a key factor for irrigation scheduling, water balance, irrigation system design and management and crop yields simulation. therefore many scientists have tried to estimate evapotranspiration in different spatial and temporal scales. remote sensing is a one of new technique in estimation of et in regional scales. so, in this study it’s tried to e...
Grid representations offer many advantages for path planning. Lookups in grids are fast, due to the uniform memory layout, and it is easy to modify grids. But, grids often have significant memory requirements, they cannot directly represent more complex surfaces, and path planning is slower due to their high granularity representation of the world. The speed of path planning on grids has been a...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
with the expression of the modernization theory as the dominant paradigm of development during the 1950s, approaches towards development were extracted from this paradigm. but with the birth of the attachment school of thought, the modernization theory was scrutinized. for latin american countries however, the attachment school of thought was considered a marxist ideology up until the end of th...
Introduction: Educational equality is a process that all practitioners are thinking about and want to put it in their supervised environment. The purpose of this study is to investigate educational equality as an unfinished puzzle in the 21st century. Methods: The present study is a review type in which keywords such as educational equality, educational inequality and educational justice ha...
When watching natural scenes, an overwhelming amount of information is delivered to the Human Visual System (HVS). The optic nerve is estimated to receive around 108 bits of information a second. This large amount of information can’t be processed right away through our neural system. Visual attention mechanism enables HVS to spend neural resources efficiently, only on the selected parts of the...
Accurate characterization of groundwater resources is required for sustainable management. Due to the cost installing monitoring wells and challenges in collecting managing situ data, data are sparse—especially developing countries. In this study, we demonstrate an analysis long-term storage changes using temporally sparse but spatially dense well where each had as few one historical measuremen...
