Polymorphic circuits are a special kind of digital logic components, which possess multiple build-in functions. In different environments, a polymorphic circuit would perform different functions. Evolutionary Algorithms, Binary Decision Diagrams (BDD) and the multiplex method have been adopted to design polymorphic circuits. However, the evolutionary methods face the scalable problem. The BDD m...

Impressum Forschungsberichte der FHDW Hannover – Veröffentlichungen aus dem Bereich Forschung und Entwicklung der FHDW Hannover. Abstract. The paper extends single-pushout graph transformation by poly-morphism, a key concept in object-oriented design. The notions sub-rule and remainder, well-known in single-pushout rewriting, are applied to model dynamic rule extension and type dependent rule a...

Existing type literature has conflicting views on desugaring polymorphic lets to lambda terms. The conflict arises because, in certain cases, desugaring does not preserve typing. We describe a transformation of polymorphic lets to monomorphic lets such that, when the monomorphic lets are desugared, the typing is preserved. Our transformation requires no changes to either term or type syntax. Th...

Bacterial flagella can adopt several different helical shapes in response to varying environmental conditions. A geometric model by Calladine ascribes these discrete shape changes to cooperative transitions between two stable tertiary structures of the constituent protein, flagellin, and predicts an ordered set of 12 helical states called polymorphic forms. Using long polymers of purified flage...

The polymorphic form-I of the fluconazole drug commonly crystallized from the solution phase could be obtained by the solid state transformation of form-II employing different process parameters. As received fluconazole-II drug melted at 138.4 degrees C. The molten drug undercooled almost to ambient temperature of 30 degrees C and solidified to a glassy mass which, on ageing for 48 h transforme...

Transformation plasticity is a deformation mechanism which occurs during phase transformation of an externally stressed material. Pressure-induced transformation plasticity of ice could be relevant to the geology of the moons of the outer solar system, and has long been postulated to occur in olivine in the earth's interior. In the present work, ice specimens were subjected to isostatic pressur...
