A discontinuity exists between modeling and objectoriented programming languages. This discontinuity is a consequence of ambiguous notions in modeling languages and lack of corresponding notions in objectoriented programming languages. It hinders the transition between software implementation and design and hampers software maintenance. This discontinuity is particularly acute for binary class ...

The solutions of the perturbed Riemann problem for the chromatography system of Langmuir isotherm with one inert component are constructed in completely explicit forms when the initial data are taken as three piecewise constant states. The wave interaction problem is investigated in detail by using the method of characteristics. In addition, the generalized Riemann problem with the delta-type i...

We consider the task of theorem proving in Lambek calculi and their generalisation to \multimodal residuation calculi". These form an integral part of categorial logic, a logic of signs stemming from categorial grammar, on the basis of which language processing is essentially theorem proving. The demand of this application is not just for e cient processing of some or other speci c calculus, bu...

The interindividual-intergroup discontinuity effect is the tendency for relationships between groups to be more competitive than the relationships between individuals. It has been observed robustly in studies conducted in the United States, a society characterized as “individualistic”. In this study, it was explored whether the effect was replicable in a “collectivistic” society such as Japan. ...

In laser material removal using a continuous wave or long-pulsed laser, the primary material removal mechanism is melting with molten metal often ejected by an assist oxygen jet. Interactions between heat transfer, oxygen diffusion and gas dynamics have been studied. In laser machining using a Q-switched solid-state laser with pulse width in the order of nanosecond, the primary material removal...

Laminar microdiscontinuities which lead to the delamination of two unidirectional layup graphite fiber-epoxy composite materials during fatigue have been characterized, and discontinuity geometry and type related to the fatigue lifetime of specimens in which they occur. Two types of discontinuities were commonly observed: voids and organic inclusions consisting of regions of excess hardener. A ...
