One of the anomalies of the capital market is accrual anomaly. This anomaly refers to the negative relationship between returns and accruals. In the case of accrual anomaly, two behavioral and rational expectations have been raised. The main purpose of this study is to explain accrual anomaly using a new approach to distinguish an anomaly interpretation of risk interpretation. For this purpos...
Due to the rapid growth of high speed network, the risk of credit-card attacks on the complex networks are also increases accordingly. Anomaly discovery from the database is a process of filtering uncertain features, so that it can be used wide variety of applications. Since the online distributed data is the communication between the remote client and the centralized server, it is difficult to...
congenital malformation (cm) will begin to emerge as one of the major childhood health problems .treatment and rehabilitation of children with congenital malformations are costly and complete recovery is usually impossible. the aim of this study was to determine frequency of cm in yazd central city of the islamic republic of iran to find out if there has been any difference in the rate and type...
This article examines the potential to improve numerical weather prediction (NWP) by estimating upper and lower bounds on predictability by re-visiting the original study of Lorenz (1982) but applied to the most recent version of the European Centre for Medium Range Weather Forecasts (ECMWF) forecast system, for both the deterministic and ensemble prediction systems (EPS). These bounds are cont...
Spacecrafts provide a large set of on-board components information such as their temperature, power and pressure. This information is constantly monitored by engineers, who capture the outliers and determine whether the situation is abnormal or not. However, due to the large quantity of information, only a small part of the data is being processed or used to perform anomaly prediction. A common...
Abstract In the present work, we evaluate accuracy of Solar Quiet Reference Field (SQRF) model for estimating and predicting geomagnetic solar quiet (Sq) daily field variation in South America Magnetic Anomaly (SAMA) region. This is based on data set fluxgate magnetometers from 12 magnetic stations Embrace Magnetometer Network (Embrace MagNet) 2010 to 2018. The predicts monthly average horizont...
[1] The climate of the Murray‐Darling basin (MDB) has been simulated using the Weather Research and Forecasting (WRF) model. WRF was implemented using a 10 km horizontal grid and run for 24 years from 1985 through 2008. The model simulated climate was evaluated against gridded precipitation and temperature observations from the Australian Water Availability Project (AWAP) at daily, monthly, int...
The application of anomaly detection has been given a special place among the different processings of hyperspectral images. Nowadays, many of the methods only use background information to detect between anomaly pixels and background. Due to noise and the presence of anomaly pixels in the background, the assumption of the specific statistical distribution of the background, as well as the co...
introduction: nager syndrome is a malformation resulting from problems in the development of the first and second branchial arches and limb buds. the cause of the abnormal development of the pharyngeal arches in nager syndrome is unknown. it is also unclear why affected individuals have bone abnormalities in their arms and legs. nager syndrome is thought to have an autosomal recessive inheritan...
turner syndrome is one of the best known chromosome anomalies in human being, by an approximate incidence of 1/2500 female at birth. the cause is a chromosomal aberration, mainly with the karyotype 45, x. ninety six patients aged 6 to 26 years with short stature were studied for chromosomal anomalies. out of these 82 were phenotypically female and 14 phenotypically male. twenty seven showed abn...
