Ternära koder för variabelt felskydd
Ternary codes for unequal error protection is a part of a communication system where different parts of the information to be transmitted can receive different amount of error protection. There are a lot of applications where the channel conditions fluctuate so that reliable or acceptable communication can not be guaranteed. Regardless whether the fluctuations of the channel are intentional or not the idea is to let the coderate decrease so that the error correcting capability can increase for the part of the information to be more protected. By using the support, the nonzero positions of the ternary code, a new binary code can be extracted with properties different from the ternary code in the sense of cardinality and minimum Hamming distance. When the channel conditions are good the receiver decodes the message using ternary decisions and receives all information included in the codeword.
Konservera eller kassera - förvaring och vård av biblioteksmaterial på 40 svenska folkbibliotek
This thesis is based on an investigation to find out in what way 40 Swedish public librarieskeep and preserve their library materials. The investigation is based on inquiries sent outto the libraries. It deals with the keeping of books with regard to external factors which havedestructive effects on library materials as well as the safety at the library buildings. It is, aswell, about the preserving work being done at the libraries.Comparisons are made with literature and accounts about preserving measures and recommendationsregarding appropriate environment in premises and depositories. The resultsshow great differences between the libraries as to the library environment, i.e.
Nytt ljus över dagbesvär vid insomni: spelar psykologiska processer en underskattad roll?
This study examined the psychological processes of autonomic arousal and distress, erroneous beliefs about sleep, worry about sleep, selective attention and monitoring and safety behaviours related to sleep, on the subject of daytime impairments associated with insomnia. The psychological processes were evaluated against as follows: sleep measures, anxiety, depression, medical disease and the use of medications. The measure daytime impairments complied with the established research diagnostic criteria. A correlation analysis indicated that psychological process, anxiety, depression and one of the sleep measures are associated with daytime impairments. The results of a multiple regression analysis proved that only erroneous beliefs about sleep, worry about sleep and safety behaviours related to sleep are linked to daytime impairments associated with insomnia.
Kan inhyrning av personal utgöra ett otillåtet kringgående av företrädesrätten?
The purpose of this paper is to highlight the issue of preferential rights in relation to the increased practice of hiring temporary staff. The object is illuminated from a diversity perspective by seeing what a circumvention of the preferential rights may have consequences for vulnerable groups on the Swedish labor market. The question of preferential rights to reinstatement is controlled in The Employment Protection Act. The preferential right is for the protection of workers made redundant due to redundancy. The use of agency workers has increased significantly in the Swedish labor market since the industry's legalization in 1993. This has created some problems in terms of preferential rights. To a circumvention of the law, shall exist requires that the measures constitute circumvention is justified, measures should have been sought to circumvent the law and been unfair in view of the particular case.
Hemautomation : Spara energi genom att automatisera hemmet
In today's society there is a significant focus on energy efficiency. Despite this, people leave lamps, televisions and computer screens etc. powered on unnecessarily. The goal of this project is to build a simple prototype for home automation where a user, via an application on a mobile phone, can switch on and off the power of an electrical products in the home and as well as being able to check whether such products are switched on or off. The prototype will also collect data on power consumption for these electrical products.
Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell
The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.
En ansats för stadsmiljön : ekosystemansatsen som vägledare för Uppsala kommuns ekologiskt hållbara stadsutveckling
The aim of this paper is in part to distinguish the ideas raised in the Swedish political debate on the new discrimination law in relation to protection of groups. Is protection by law against discrimination needed for the individual or the group? If it is needed for members of groups, are these groups viewed on as static or variable. Are there any conflicts present between group interests? We link these ideas to three different theoretical perspectives: multiculturalism, feminism and intersectionality and further examine the differences and contradictions between the perspectives represented by members of parliament.

Simulering av en framtida presslinje - en analys av design och prestanda
Problem areaAlfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an increased demand of heat exchanger in the future. This increased demand is not something that existing lines will manage. To build new lines cost a lot of money and take time so it is essential that new lines are correct from the start and not need to be rebuilt or a lot of time spent to trim it.GoalThe goal is to achieve 100% theoretical utilization of the press (the press shall press the amount of plates it is designed for).
Barns Behov i Centrum- För alla barn? : En kvalitativ studie om handlingsutrymmet vid användandet av BBiC i arbetet med ensamkommande flyktingbarn
This study regards the Swedish documentation system, BBiC, which is translated from the English version LACS. BBiC is created to make sure that the children?s needs are put in centre of attention in child protection investigations. The BBiC-system becomes problematic regarding unaccompanied refugee children because of the parent-perspective which is a keystone in the system. Therefor BBiC creates discretion for the social worker which is not BBiC: s original intension.
Svensk yttrandefrihet i ett EU-perspektiv : - Hur svenska medborgare kan komma att få ett svagare meddelarskydd och ensamansvar ioch med EG-rättens konflikt med svensk grundlag vid grundlagsregleringen 2010
AbstractTitle: Swedish freedom of speech compared to european freedom of speechNumber of pages: 57Author: Gabriella BoodeTutor: Göran SvenssonCourse: Media and Communication Studies CPeriod: Spring 2009University: Division of Media and Communication, Department of Information Science,Uppsala UniversityPurpose/Aim: The purpose with the dissertation is to see if there has been a limitation inSwedish freedom of speech since parts of the European union laws is superiour to theSwedish constitution as freedom of the press regulations and freedom of speech constitution.A more narrow purpose is to find out how the specific Swedish rights such as individual?slegal right to publish information are influenced by the European union laws and are superiorto the freedom of the press regulations and freedom of speech constitutionThe survey will also try to find out the effectiveness with the Lisbon Strategy ?s emergencybrake and its purpose to protect the Swedish freedom of the press regulations and freedom ofspeech constitution. How big is the difference between the different member states concerningthe protection of the freedom of speech?Material/Method: The data collected for this thesis is retrieved through personal interviewswith representives from experts with in the field as Uppsala University and the SwedishGovernent.Main results: It is obvious that Sweden has the strongest protection of freedom of speechcomparing to the other EU member states. No other EU country has as detailed constitution asthe Swedish constitution TF and YGL.
Användning av WHO:s checklista för säkerhet vid operationer och operationssjuksköterskans medverkan.

Konstruktion av turbinmodell för kaplanturbiner
Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.
?r omfattande varum?rkesr?ttigheter nyckeln till innovation? En utredning av risker vid individanpassning av kl?der p? den europeiska marknaden
This thesis examines the legal boundaries of third-party use of trademarks in the European customized clothing market. The purpose is to determine under what circumstances third parties may legally modify and sell trademarked apparel without infringing on trademark rights. The study employs a legal dogmatic method, analyzing EU trademark law, case law, and legal doctrine to clarify the scope of exclusive rights and their limitations. By analyzing key EU case law, the study further illustrates how the legal framework has been interpreted and applied in cases concerning third-party trademark use.
Given the increasing demand for customized fashion and the rise of new business models in the clothing industry, this topic holds significant legal and economic relevance.
Additionally, Schumpeter?s theory of creative destruction provides a theoretical perspective on how trademark restrictions impact innovation and market competition.
