Implementering av 1D-DCT

IDCT (Inverse Discrete Cosine Transform) is a common algorithm being used with image and sound decompression. The algorithm is a Fourier related transform which can occur in many different types like, one-dimensional, Two-dimensional, three-dimensional and many more.The goal with this thesis is to create a fast and low effect version of Two-dimensional IDCT algorithm, where techniques as multiple-constant multiplication and subexpression sharing plus bit-serial and bit-parallel arithmetic are used.The result is a hardware implementation with power consumption at 19,56 mW..

Tvådimensionella rum

We are always surrounded by space, not just only in a room with four walls, but also when we are outdoors.Constantly we move in a flow of space that changes whenever we move. Unaware we are affectedby this threedimensional surrounding of ours, and it reacts with our perception. Many times, we chooseto translate it into something Two-dimensional, for example when we take a photo, recording a movie orframing a view with a window. It helps us to catch a moment, a piece of reality and restore it in our ownway. In this project I?ve chosen to explore this process, to interpret and create my own theories about thistranslation from space to a Two-dimensional surface.

Dimensioner. Mellan 2D och 3D, en undersökning av yta och innehåll

A project exploring the boundaries between 2D and 3D. What is surface and what is substance? A countinuation of previous projects where I?ve examined the journey from two dimensional paper to three dimensonal objects. This project deals with the journey from three dimensonality back into a flat two dimensional surface, and the question if something can be both 2D and 3D at the same time. I decided not to center the project around a specific item, but rather let the project itself be in focus.

Sequi : Tredimensionell sequencer

Music production software has a strong tradition of Two-dimensional graphical user interface (GUI), in which the time line is represented as a flat composition either horizontally (from left to right) or vertically (from top to bottom). In my degree work titled Sequi, I approach music composition from a different angle. Instead of a Two-dimensional time line with only two possibly ways of progression (forward or backward) I constructed a three-dimensional GUI with the maximum of four different ways of progression from any given point in a composition. The height axis is used to describe time-intervals (the time between downbeats) and the wide and depth axes are used to describe progression from one sound to another..

Ersättning för markåtkomst avseende tredimensionellt (tunnel) intrång i fastighet

Chapter 1. 1 § jordabalken (1970:994) defines property as land that includes area, which is divided into properties.A three-dimensional property must be firm with a closed volume where top and bottom are specified. The property boundaries are described clearly according to Chapter 4. § 27 fastighetsbildningslagen. A three-dimensional property can undermine a traditional property, as well as a three-dimensional property.

Tredimensionell fastighetsindelning : med fokus på tillbehörsproblem

Real estate is defined as ground, which is divided into property. Ground means every part of the surface, which is situated within the country. There is no legal definition of property to be found. Property is usually explained as every unit, which legally should be registered in the register of landed properties. To constitute a property the property must permanently be suited for its purpose.

Utvärdering av dimensionell stabilitet i PWR-patroner i Ringhals

Dimensional stability is an important aspect of fuel mechanical design and licensing of new fuel designs for nuclear power plants. Dimensional changes within the reactor can affect the safety margins against overheating of the cladding and the pellets, therefore it is crucial that the dimensional changes are kept to a minimum.The profits per produced kiloWatt hour continue to decrease for the Swedish nuclear power plants. Some reactors are even operated with a calculated loss. To reduce fuel costs and thereby improve the profit some reactors are operated with higher uranium enrichment, so that the assemblies can reach a higher average burnup. This increases the neutron fluence to the pellets, cladding an spacers.

3D-avatarskaparen

This project report shows the work around a mockup to a three-dimensional avatar-making application. An avatar-making application is a computer-based software program in which it is possible to create your own personal virtual character. The possibility to use three-dimensional avatars can in the future be essential for adding extra personal information or characteristics to social communication over the internet or over mobile phones. The problem of transforming a physical form and reconstruct it to a virtual basis has been an important problem to solve for many companies and software developers in the, for instance, virtual worlds area. Methods and ideas over making this transformation is the key throughout this project.

Undersökning av modulationsscheman för existerande bredbandsteknologier

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood

Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.

Krafter på rörsystem vid transient flöde : En jämförelse mellan RELAP5 och Fluent

At Forsmarks Kraftgrupp AB (FKA) forces on pipe systems due to transient flow are frequently calculated as a step to verify their structural integrity. In nuclear industries these forces are often calculated with a one dimensional thermal-hydraulic analysis-code called RELAP5. When calculations regarding more complex geometries are needed, the three dimensional code Fluent is often used. This code is highly time consuming and requires large computational power.This projects aim is to compare calculations of pressure, flow and forces carried out by RELAP5 and Fluent for an arbitrary pipe section during transient flow conditions. This has been accomplished by constructing a simple geometry for which a transient flow is simulated in both programs.

Real-time rendering of large terrains using algorithms for continuous level of detail

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering

This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.
