This work is divided in to two distinct parts. In the first part a model is developed to assess the redistribution of wave energy about an offshore array of overtopping type wave energy converters. The model is based on a classical analytical solution for diffraction about a breakwater which is modified to consider an array of dissipating, reflecting and transmitting breakwater segments, which ...

Static-semantics determines the validity of a program, while a type-checker provides more speciic type error information. Type-checkers are speciied based on the static semantics speciication, for the purpose of identifying and presenting type errors in invalid programs. We discuss a style of algebraically specifying the static semantics of a language which facilitates automatic generation of a...

In spacecraft engineering a paradigm shift is emerging with the tendency from traditional, single, large, and multifunctional satellites towards cooperating, distributed small spacecraft systems. In particular modern miniaturization techniques allow realization of satellites with continuously smaller masses, and thus enable cost-efficient implementation and launch of distributed multi-satellite...

The past decade has seen an increased interest in Autonomous Micro Aerial Vehicles (MAVs). Rotary wing MAVs such as quadrotors, can operate in confined spaces, hover at any given point in space and perch or land on a flat surface. This makes the quadrotor a very attractive aerial platform with tremendous potential. Our main goal was to design and prototype an MAV that weighs less than 30g and i...

BACKGROUND Glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. This study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation. METHODS The study was a cross-sectional study evaluating patients with unstable shoulder j...

Neste trabalho, o corante azul de metileno foi imobilizado na superfície do acetato de celulose modificado com dióxido de titânio produzindo um material híbrido sólido denominado de CA-TiO 2 MB. O experimento produziu uma quantidade de 1,8 mmol g de TiO 2 incorporado no acetato de celulose e uma quantidade de 0,170 0,005 mmol g de azul de metileno adsorvido na superfície do CA-TiO 2 . Um eletro...
