This paper describes the implementation of a custom DSP system to accelerate image processing algorithms used in the field of digital holography. The system, implemented on an FPGA platform, is intended for real-time reconstruction of images captured on a large image sensor. Due to the large amount of processing information, it is not possible to perform a HDL simulation of a complete image recons
Lake Urmia is a hypersaline lake in northwest Iran. Due to its unique aquatic ecosystem it has been designated as a Biosphere Reserve by UNESCO and a National Park under the 1971 Ramsar Convention. The biodiversity of the lake is determined by its salinity and Artemia urmiana is the dominant invertebrate and also the key element of the lake’s food chain. The lake is relatively shallow and satellit
Implementation-tailored review of Road Safety Audit has been made. Best practices in procedures, elements, essential documents and training content of interest for the Baltic countries are presented.
Time reversal is based on recording the wave field by a set of transducers, time reversing the recorded signal, and retransmitting the result. An iterative time reversal algorithm that retrofocuses an electromagnetic wave field to its controllable part is establish. The algorithm utilizes the 'equal fields on the boundary' condition, which can be archived with the wave-guided controllable part of
Abstract in French L'AUTEUR RAPPELLE COMMENT L'EAU PARTICIPE AUX PHENOMENES QUI CONDUISENT A LA DETERIORATION DU BETON ET INDIQUE DES EXEMPLES DE CONDITIONS D'HUMIDITE CRITIQUE DANS LES PHENOMENES DE REACTIONS ALCALI-SILICE, D'EFFLORESCENCES, ET DE CORROSION. IL DECRIT LE COMPORTEMENT HYGROTHERMIQUE DU BETON A L'AIDE DES LOIS DE CONSERVATION DE L'ENERGIE ET DE LA MASSE. DANS LE CAS DU BETON DURCI,
Due to the nature of the engine cycle, heat transfer has a significant role in the estimation of engine efficiency. The effects are quite well known in the classic combustion concepts, compression ignition (CI) and spark ignition (SI) combustion. But for the newer, low temperature combustion (LTC) concepts, these effects are not that well known. In this paper, a commercial computational fluid dyna
Popular Abstract in Swedish Avhandlingen syftar till att utifrån 11-åriga barns berättelser om sina familjer och hur de själva uppfattar sina familjer och sin fostran beskriva, analysera, förstå och tolka villkoren för denna fostrans- och socialisationsprocess samtidigt som den pågår. Forskningsproblemet kan formuleras: hur och vad uppfattar och berättar barn om sina upplevelser av familjeliv och The thesis aims to describe, analyse and interpret the conditions of the upbringing process and the socialization process in a group of eleven-year-olds while the process is still ongoing, and to do this with the help of the eleven-year-olds? narrations about their families and about how the children themselves view their families and their upbringing. The research approach is inspired by phenomen
In this work radiative properties of neutral elements with one or two electrons outside closed subshells have been investigated. Using laser techniques in connection with atomic beams selective excitation of Rydberg states was performed. Most of the studied states were populated with two-step excitation. Some states were reached directly from the ground state or from a metastable state and occasio
Traditionellt sett hör idrotten och den fysiska leken ungdomen till, men idag är det inte ovanligt med regelbunden och målinriktad motion också högre upp i åldrarna. Samtidigt har idrotten blivit allvarligare och forskningen betonar starkt och entydigt sambandet mellan ett livslångt motionerande och ett hälsosamt liv. I denna studie belyses motions- och hälsostrategier hos äldre män och kvinnor sa
