Affine Processes and Applications in Finance

Damir Filipovic

We provide the definition and a complete characterization of regular affine processes. This type of process unifies the concepts of continuousstate branching processes with immigration and Ornstein-Uhlenbeck type processes. We show, and provide foundations ...

Moving object detection between multiple and color images

Touradj Ebrahimi, Emrullah Durucan

There are several publications dedicated to the description and analysis of change detection between two gray-value images. This paper introduces new methods to detect moving objects between multiple images and to detect changes between color images or any ...

Dynamic Proxies for Classes: Towards Type-Safe and Decoupled Remote Object Interaction

Patrick Eugster

A dynamic proxy object is a typed proxy, created at runtime, conforming to a type specified by the application. Such an object can be used wherever an expression of the type it was created for is expected, yet reifies all invocations performed on it. This ...

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 for objects and classes which can have types as members. Type members can be aliases, abstract types, or new types. The type system can model the essential concepts of Java's inner classes as ...

Evolutionary Bits'n'Spikes

Dario Floreano, Gilles Caprari, Jesper Blynel

We describe a model and implementation of evolutionary spiking neurons for embedded microcontrollers with few bytes of memory and very low power consumption. The approach is tested with an autonomous microrobot of less than 1 in^3 that evolves the ability ...

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 ...

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 ...
