Urban sprawl is a hot topic of global concern with increasing dramatically and impact on ecological environment. But there is not a mature method to explain the detail of process of urban sprawl and dynamic changes. In this paper, the dynamic changes of urban is studied based on 1980, 1988, 1994, 2000 and 2005 five remote sensing images of Shenzhen. It is distinguished three types including inf...

De Finetti’s conception of events is one of the most distinctive aspects of his theory of probability, yet it appears to be somewhat elusive. The purpose of this note is to set up a formal framework in which a rigorous characterisation of this notion, and its cognate modelling assumptions, gives rise to a detailed formalisation of the betting problem which underlies the celebrated Dutch Book Ar...

In a climate marked by expanding scholarship in ethnic and racial studies alongside sweeping changes in universities and the conditions of academic work, we seek to explore the nature of and challenges for critically engaged research, teaching and scholarship on race and racism. In particular, we look at the connection between academic scholarship and political engagement and activity that we a...

For realistic simulation, it is essential to register the two worlds, calculate the occlusion realm between the real world and the virtual object, and determine the location of the virtual object based on the calculation. However, if the constructed map is not accurate or the density is not sufficient to estimate the occlusion boundary, it is very difficult to determine the occlusion realm. In ...

Fiber reinforced composites are high strength filling materials composed of conventional composites and glass fibres. They exhibit extensive applications in different fields of dentistry. This clinical report present a case where FRC technology was successfully used to restore central maxillary incisor edentulous area in terms of esthetic-cosmetic values and functionality.

This paper deals with continuous frames and continuous Riesz bases. We introduce continuous Riesz bases and give some equivalent conditions for a continuous frame to be a continuous Riesz basis. It is certainly possible for a continuous frame to have only one dual. Such a continuous frame is called a Riesz-type frame [13]. We show that a continuous frame is Riesz-type if and only if it is a con...

Wood-frame residential roof failures are among the most common and expensive types of wind damage. Hip roofs are commonly understood to be more resilient during extreme wind in relation to gable roofs. However, inspection of damage survey data from recent tornadoes has revealed a previously unstudied failure mode in which hip roofs suffer partial failure of the framing structure. In the current...

PVC frame cutting process by guillotine is a common method that attracted attention of car parts and PVC decorating furniture producers. In this paper, the effects of main parameters such as cutting speed, lubricants and cutting frame holder pressure force on PVC frame section surface smoothness is investigated by experimental methods on a specified PVC frame sample and then by FEM simulation u...

amebiasis caused by entamoeba histolytica is still mentioned as one of the major health problems in tropical and subtropical areas. e. histolytica has recently been redescribed as two distinct species; e. histolytica and e. dispar. in the present study, we characterized the 70 kda heat shock protein (hsp70) of e. dispar at molecular level and compared it with that of e. histolytica. with these ...
