Our goal is to develop a scienti c understanding of the kinds of mandatory controls needed to support data integrity. There is general consensus that integrity is an important problem and requires some kind of mandatory controls for its solution. At the same time, inspite of considerable e ort [17, 18, for instance], there is little consensus on what is meant by the two key terms: mandatory con...

For many researchers and developers in information and communication technology in education (ICTE), the transfer of knowledge from research into educational practice is slow and limited. For most researchers concerned with changing practice, the failure to make a significant impact is attributed to those who practice in education, whilst those in practice see technical research as irrelevant t...

â â â  reports indicate that the mahabad dam has been silting up more than it was expected. this research has been tried to study the causes and the agents of these changes. a duration of two years periods (that is from october 1986 to october 1987 and october 1991 to october 1992) was taken up to compare and then to determine the role of the sedimentation on these changes. results show that th...

one of the water resources modeling requirements is sufficient knowledge of long-term series of meteorological and hydrological parameters. in this study the nearest neighbor resampling method presented by lall and sharma was developed. in the developed model, the knn regression was used for time series forecasting instead of local polynomial used in the developed algorithm by prairie. in this ...

Background Given that school-age students, as active road users, are more vulnerable to injury compared with other pedestrians, a large number of them, following an injury, may either fail to go to school at least for a short time or even suffer from disabilities for the rest of their lives. The aim of this study was to determine safe behavior in road crossing using the theory of planned behavi...

Skid resistance and road condition are common indices of road safety; therefore providing adequate skidding resistance will reduce the incidence of road accidents. The surface macrotexture has a large effect on the characteristics of road surface skidding, which is the focus of this research. During the study, the mean texture depth of the road surface was measured, in order to determine the co...
