one of the most important goals in geomagnetic investigations is detecting local anomaly locations. regional anomaly can be simulating as a trend surface, and local anomalies will be detected by comparison of measured data and simulated trend surface. the problem is trying to find best coefficients of trend surface model using inverse methods based on modern optimization techniques, which are f...

according to this reality that iron bulks because of having ferromagnetic minerals, they have high magnetic intensity, in mining explorations most usual geophysical method  suggested to explore these resources is magnetic method. basically in order to process and interpretation of magnetic anomaly maps several methods be used of which most of these methods are based on try and error. one of usu...

regional odontodysplasia (ro) is a rare developmental dental anomaly with an unknown etiology. it is more often seen in girls than boys. treatment of ro depends on the individual case. the aims of treatment should include aiding mastication and speech, improving aesthetics, reducing the psychological impact of the anomaly, allowing normal jaw growth and development, and if possible protection o...

OBJECTIVE To evaluate the National Congenital Anomaly System (NCAS). METHODS The NCAS in England and Wales based at the Office for National Statistics and the various regional registers that exchange data with it were examined, based on guidelines for evaluating public health surveillance systems, published by the Centres for Disease Control (CDC). Data relating to congenital anomaly notifica...

To improve the accuracy and efficiency of space-time analysis, spatio-temporal neighbourhoods (STNs) should be investigated and analysed in the classification, prediction and outlier detection of space-time data. So far most researches in space-time analysis use either spatial or temporal neighbourhoods, without considering both time and space at the same time. Moreover, the neighbourhoods are ...

In the recent times, autoencoders, besides being used for compression, have been proven quite useful even for regenerating similar images or help in image denoising. They have also been explored for anomaly detection in a few cases. However, due to location invariance property of convolutional neural network, autoencoders tend to learn from or search for learned features in the complete image. ...

The aim of this work is to propose a first-order estimate of the crustal and lithospheric mantle geometry of the Arabia–Eurasia collision zone and to separate the measured Bouguer anomaly into its regional and local components. The crustal and lithospheric mantle structure is calculated from the geoid height and elevation data combined with thermal analysis. Our results show that Moho depth var...

PURPOSE To assess the regional patterns of infant mortality due to lethal congenital anomalies, and the potential reasons for the regional patterns. METHOD The study analyzed 2,507 infant deaths due to lethal congenital anomalies among 1,178,452 live births in 9 of the 12 Canadian provinces and territories from 1990 to 1995 recorded in Statistics Canada's live birth and death data bases. RE...

Regional odontodysplasia is a nonhereditary, uncommon developmental abnormality of teeth. Females have more predilections for regional odontodysplasia. The enamel, dentin and pulp of teeth are affected and radiographically, teeth are described as "ghost teeth". Many of these :eeth do not erupt and have an increased risk for caries and periapical inflammation. Since the literature on regional od...
