WAN-optimering för sjöfarten : En möjlighet att effektivisera datakommunikationen till sjöss

Verksamheten ombord på fartyg blir mer beroende av datakommunikation och många av arbetsuppgifterna ombord underlättas genom att besättningen kan nå information lagrad på annan plats. Fartygens bredbandsanslutning sker till största delen via satellitkommunikation där långa avstånd och begränsad datahastighet resulterar i att datakommunikationen blir ineffektiv. I denna studie undersöks vilken prestandaförbättring som utrustning för nätverksoptimering kan innebära för långsamma WAN-förbindelser via satellit. Undersökningen visade att det största problemet med anslutningar via satellit är den signalfördröjning som uppkommer vid långa sändningsavstånd. Detta medför att det blir prestandaproblem för datatrafiken och användare upplever anslutningen som långsam.

Känsloigenkänning i form av ansiktsuttryck med Kinect

Facial expressions are a part of our body language that helps us to clarify the verbal communication between humans. We use our facial expressions every day, both consciously and unconsciously, to express emotions and attitudes depending on the situation. The hypothesis of the study is: Given a facial expression, how well can Microsoft Kinect, as an input method, determine a person?s feelings with the two algorithms Naive Bayes and Sequential Minimal Optimization? The feelings are limited to happy, sad, surprised and disgusted. With the help of Kinect, a person?s facial data, both coordinates of the face and parameterized data, were saved and used for machine learning.

Luftburen förnödenhetsförsörjning : En nödvändig metod eller ett exklusivt förfarande?

Studien omfattar ämnesområdena luftburen försörjning, logistikkoncept, operativ och taktisk logistik. Då försörjning av förband påverkas av insatsens operationsplan, den fysiska miljön och den hotbild som råder, är det en nödvändighet att det logistikkoncept som styr hur understödet genomförs är av en robust och adaptiv karaktär.Syftet med studien är att undersöka vad ett logistikkoncept vinner på att ha luftburen förnödenhetsförsörjning som en ingående parameter samt att undersöka hur Försvarsmaktens marktaktiska förband påverkas av att understödjas av ett sådant koncept.Studiens empiri utgår huvudsakligen från de svenska Försvarsmakts doktriner och dokument vilken kompletteras genom intervjuer samt utländsk stödlitteratur. Analysverktyget utgår ifrån Moshe Kress teori om Operational Logistics. I studien analyseras logistikkoncept som tillämpats vid tre olika insatser.Av studiens analys framgår att ett logistikkoncept svårligen kan vara av robust och adaptiv karaktär om konceptet saknar möjligheten att tillämpa luftburen försörjning som metod. En viktig slutsats är att metoden kan öka understödda förbands förmåga till uthållighet och verkan..

NATO operativa planeringsmodell (GOP) prövad i slaget om Midway

Syftet med denna uppsats var att pröva om de centrala begreppen i Guidelines for OperationalPlanning GOP är relevanta/allmängiltiga, genom att placera dem i ett historiskt perspektiv. Jagvalde att analysera den amerikanska planeringen vid slaget om Midway med hjälp utavGuidelines for Operational Planning. Från de centrala begrepp som återfinns i GOP har jagundersökt om dessa går att spåra i den amerikanska planeringen som skedde före och underslaget vid Midway.Midway var vändpunkten för kriget i stilla havet. Efter en serie av fantastiska segrar erhöllJapans flotta ett enormt bakslag. Fyra hangarfartyg och huvuddelen av de mest erfarna piloterna iJapan var tillintetgjorda.

Flockning och förtjockning i High-Rate-förtjockare ? en jämförelse med konventionell förtjockarteknik och lamellsedimentering.

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

Verksamhetsrelaterade uppsägningar i Sverige och Polen : En komparativ studie

This thesis investigates similarities and disparities between Swedish and Polish Labour Law concerning dismissals due to operational requirements and group redundancies. The study focuses on three important elements where the employers? liberty is legally infringed upon in a procedure of notice. These elements concerns the legal conditions of notice that must be fulfilled, the rules of the procedure and the rules for employment protection that is granted in connection with dismissals due to operational requirement or group redundancies. In the thesis there is a comparative map that outlines the most important rules within the Swedish and Polish legal systems concerning the subject.

Hälsofrämjande och förebyggande elevhälsa : från nationell till kommunal och lokal nivå

The perspective on health among school pupils needs to be extended. School is animportant arena for the promoting of health among youth, primarily from a healthpromoting perspective and a proactive perspective. A holistic approach has gatheredsome ground in the policy documents for the nine year compulsory school in Sweden, butin what way, and what effect does it have on the governing authorities and on schoollevel?The aim of the study is to investigate the coherence between national, municipal andlocal levels regarding the view on health among pupils. In order to do this, the guidelinesfor pupil health in the municipality of Örebro and operational plans for seven F9 schoolsin the municipality of Örebro will be studied and compared to the government bill?Health, learning and sense of security?.

Legitimitet och nekande tvångsmakt i Operation Desert Storm

When are aerial bombing strategies effective in coercing target states? According to the recent research debate there is a consensus that denial strategies may be an effective instrument for coercing states to change their politics. This study is based on Belkin?s theory which argues that the effectiveness of denial strategies may depend in part on the domestic legitimacy of the target states? regimes. From a political standpoint, aerial denial effectiveness can be considered more likely to coerce when political leaders of target states lack domestic legitimacy rather than when they are legitimate.   The purpose of this study is to contribute an explanation of a condition where denial strategies are more likely to succeed.

y måste bero av x ? gymnasieelevers förståelse av det matematiska begreppet funktion

Objective: The aim of the study is to describe pupils' understanding of the mathematical concept of function. How do pupils define the concept of function? What images of the concept of function evoke when they solve tasks, which involve identifying and constructing functions?Theory: A student's thinking about a mathematical concept depends on more than just the formal definition of the concept; therefore Tall and Vinner introduce the term concept image to describe the role cognitive structures play when students learn about concepts. The cognitive structure includes all mental images, associated properties and processes that an individual associates with a given concept. According to Sfard, an individual's understanding of mathematical concepts may have different character: an operational conception, where a concept is conceived as a process and a structural conception, where the given concept is conceived as an object, that is, as a whole.Method: 16 pupils at the Science Program at two different upper secondary schools inSweden answered a questionnaire on the mathematical concept of function.

Aerodynamisk optimering av vindkraftverks rotorblad med en genetisk algoritm, BEM-teori, och XFOIL

This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.

Ekosystemansatsen på landskapsnivå

The Convention on Biological Diversity (CBD) promotes the Ecosystem Approach (EA). In this thesis it is analyzed how the EA approach could be applied to regional management of coastal areas in Sweden. The aim of this report is to compare management for preserving biodiversity on a landscape level in two regional coastal areas in Uppsala and Västra Götaland respectively. In Uppsala, one of the plans consists of a previous nature reserve and in Västra Götaland, a Regional landscape strategy has been established. The ecosystem approach is used as a theoretical framework in this thesis.

Grundskollärares informationsbehov och informationsförsörjning: en intervjuundersökning ur ett rollperspektiv

This thesis deals with the information needs and information provision of teachers in compulsory school, from a role theoretical perspective. The object is to investigate teachers opinions on their information needs and information provision. The following questions have been used to approach the problem: Which are the information needs of teachers in compulsory school? How do teachers get the information they need? Which difficulties and deficiencies do teachers experience in their information provision, and what does the ideal situation look like? The theoretical frame of reference consists of a model of the information seeking of professionals, which is based on role theory. Qualitative interviews have been carried out with nine teachers.
