The presence of clustered microcalcifications is one of the earliest signs in breast cancer detection. Although there exist many studies broaching this problem, most of them are nonreproducible due to the use of proprietary image datasets. We use a known subset of the currently largest publicly available mammography database, the Digital Database for Screening Mammography (DDSM), to develop a c...

Abstract In order to understand the mechanism of surf-riding/broaching profoundly, four- degree- of-freedom(4DOF) maneuvering equation (surge, sway, yaw and roll) is simplified a one- degree-of-freedom (1DOF) equation, fourth-order Runge-Kutta method used integrate 1DOF surge in time domain analyze two motion states ship during surging surf-riding. The critical Froude number calculated using Me...

In contemporary debates on risk in modern societies, on reflexive modernity and a general crisis of knowledge, concepts and terms such as ignorance, non-knowledge or negative knowledge are used to denote that there can be knowledge about what is not known. Many of these terms are not only used with different meanings, sometimes antithetic to one another in their implications, but they often pro...

In papers [2,4,5] the solution relations and algorithm of method block iterations solving linear nonlinear equations by semivanalytic finite element for curvilinear inhomogeneous prismatic bodies are realized. paper [1], a numerical study convergence solutions was performed, wide range test problems with smoothly abruptly changing physical geometric characteristics in elastic resilient-plastic ...
