A Nominal Theory of Objects with Dependent Types

Martin Odersky, Vincent Cremet, Matthias Zenger

We design and study newObj, a calculus and dependent type system forobjects and classes which can have types as members. Type members canbe aliases, abstract types, or new types. The type system can modelthe essential concepts of Java's inner classes as we ...

Analysis of the microstructures ("rosettes") in the superposition of periodic layers

Roger Hersch, Isaac Amidror

Superpositions of periodic dot screens are largely used in electronic imaging in the field of color printing. In such superpositions the interaction between the superposed layers may cause new structures to appear which did not exist in any of the original ...

New structured beds formed by zeolites deposited on metallic and ceramic supports

Albert Renken, Lioubov Kiwi, Benoît Louis

The title bed is developed with in situ cryst. growth of zeolite ZSM-5 on different supports; metallic grids and glass fibers. The materials are characterized by diverse physicochem. methods. The chem. pretreatment of the support is a crucial parameter for ...

Transducer design with global parametric optimization

Yves Perriard

To design transducers or motors, it requires the analysis of a lot of parameters such as length, temperature, efficiency, weight, etc. To obtain the optimum results for given specifications, the solution is to analyze globally all the free parameters in on ...

Gallium zigzag chains as an ordering principle in h5-2,5-di-(t-butyl)phospholylgallium(I)

The solid state structure of h5-2,5-di-(t-butyl)phospholylgallium(I) 1 was detd. by x-ray diffraction at 190 K. The mols. of 1 are partly organized in a new type of structure: a Ga zigzag chain in which the arom. phospholyl rings alternate on both sides of ...

Spectroelectrochemistry of Nanostructured NiO

Ulf Anders Hagfeldt

Transparent nanostructured NiO electrodes were prepd. by heating Ni(OH)2 sol-gel films at 300-320°. Nanostructured NiO (bunsenite) behaves as a p-type semiconductor and has an indirect band gap of 3.55 eV. It shows a strong anodic electrochromic effect, as ...

A low weight resistant porous glass fiber having physical chemical or biological properties

Albert Renken, Lioubov Kiwi, Igor Iouranov

A low weight resistant porous glass fiber of type I is disclosed with a developed specific surface area of 5 times to 120 times the outer surface of a standard glass fiber, and a material having physical, chemical or biological reactive properties deposite ...

Equations de type implicite avec contraintes

Chiara Tanteri

In this thesis we will treat the Dirichlet problem for systems of implicit equations, i.e. where Ω ⊂ Rn is an open set, u : Ω → Rm, Fi : Ω × Rm × Rm×n → R, m,n ≥ 1, are continuous functions and φ, the boundary datum, is given. At first we will be intereste ...

Electrochemical behaviour of DSA type electrodes prepared by induction heating

Christos Comninellis, György Foti

DSA type electrodes (IrOx/Ti) were prepd. by induction heating technique which allows a rapid decompn. of the precursor under anaerobic conditions. With this type of electrode, an activation process is obsd. in cyclic voltammetry which can be related to th ...

Luminal heterodimeric amino acid transporter defective in cystinuria

Lukas Kühn

Mutations of the glycoprotein rBAT cause cystinuria type I, an autosomal recessive failure of dibasic amino acid transport (b(0,+) type) across luminal membranes of intestine and kidney cells. Here we identify the permease-like protein b(0,+)AT as the cata ...
