Trimning av lead och lag filter

The work describes the development of an adjustment algorithm that will replace today?s manual adjustment of Lead- and Lag-filters at ABB Robotics industrial robots. The adjustment is mainly for the filter parameters in the control system.Three different algorithms have been created to replace the manual adjustment. One of them is based on the criterion from the manual adjustment and another one on optimization of the sensitivity function. The last one is a combination of the two.The report describe the development of the algorithms and how they behave during simulations and tests on real robots.

Radomoptimering för luftburna störsändarkapslar

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

Planering av väginvesteringar :

The problems around and the planning of wood flow is some of the most complex issues in the forest-sector. The experience and overview of the single employees is crucial for the possibility of correct tactical and economical decision-making. The increasing demand of savings and shorter reaction-times with greater flexibility in the wood-supply-chain, makes solutions and aids for improved effectiveness in the work and processes according to wood-flow urgent. Holmen Skog is starting to develop a new forest-road-management-system. The system will facilitate the work according to construction, improvements and updating the standard of roads.

The financial crisis in 2008, effected companies around the globe and forced them to change their operational strategies, in order to survive. Companies with international links needed to consider external effects and due to that adapt their strategies on a global level. Demands for goods and service were decreasing and companies could only manage the cost during a recession to not face bankruptcy. Organisations need to reconsider their optimal strategy as this will determine their future outcome when managing a crisis as the one in 2008. British Airways - Air Cargo is a global company with an international network which serves about 80 countries, with about 200 destinations.

Operational Business Intelligence : en studie i automatisering av beslutsprocessen vid kreditbedömningar

Operational Business Intelligence (OpBI) är en typ av Business Intelligence som används i det operativa arbetet och det röner mer och mer intresse. I samarbete med ett företag har en fallstudie genomförts med syftet att etablera och kontextualisera riktlinjer för att kunna införa en ökad automatiseringsgrad i en OpBI-lösning som används för kreditbedömning av fakturor.Studien har fokuserat på att undersöka vilka faktorer som påverkar finansieringsbolag vid val av automatiseringsgrad, val av parametrar att använda vid kreditbedömning samt val av antalet regler som styr automatiseringen. Inom ramen för fallstudien har en analys av det utvalda systemet utförts och intervjuer gjorts med kreditupplysnings­bolagen som är leverantörer av de externa para­metrarna samt intervjuer med sju finansieringsbolag som använder det utvalda systemet.Fall­studien har resulterat i 19 riktlinjer. Resultatet visar att ju högre volym som hanteras, ju högre tidspress det finns i pro­cessen och ju större tillit som finns för en automatisering, desto högre auto­matiseringsgrad väljs..

Nätverksoptimering med öppen källkod : En studie om nätverksoptimering för sjöfarten

Detta examensarbete handlar om hur datatrafik över en satellitlänk kan optimeras för att minska laddningstider och överförd datamängd. Syftet med studien är att undersöka i vilken omfattning datatrafik mellan fartyg och land via satellitlänk kan styras så att trafiken blir effektivare. Genom att använda DNS-mellanlagring, mellanlagring av webbsidor samt annonsblockering med pfSense som plattform har examensarbetet utfört experiment emot olika hemsidor och mätt laddningstid samt överförd datamängd. Resultatet visade att det fanns stora möjligheter att optimera nätverkstrafiken och de uppmätta resultaten visade på en minskning av datamängden med 94% och laddningstiderna med 67%..

Parametriserad modell av motorprototyp med Solidworks

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

Styrningen av den svenska förskolan

In this study we have focused on the operational management of the public pre-school in Sweden. We have studied how the governance system is designed, why it is designed this way and what impact it has on the operational management. This has been analyzed from a theory stating that there are two types of organizations: pay-driven and function-driven. Through a case and document study we came to the conclusion that the pre-school is a function-driven organization but is nowadays acting on a market and have adopted characteristics of a pay-driven organization. We connect this change to the phenomenon New Public Management.

Planering av vägupprustning med hjälp av GIS och optimering : en fallstudie på Holmen Skog

The objective of this thesis was to develop a method for the planning of road upgrading at Holmen Skog, a Swedish forest company. A critical issue for creating such plans is to identify roads that are suitable to upgrade to a standard that can handle heavy traffic during spring thaw, since spring thaw is a bottle neck for transporting timber. The method was tested in a case study at a district. The work consisted of two parts. The first was to retrieve and prepare geographical data for the roads.

Implementing a receiver in a fast data transfer system : A feasibility study

This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing.

Strategisk och taktisk planering samt länken där emellan : analys av planeringsprocessens genomförande vid SCA Skog

To effectively manage a forest resource for both economic and other values good planning is required. The problem is complex since you want to know which forest to cut and when. Often a hierarchical planning structure is applied, including strategic (long-term), tactical, (medium-term) and operational level. Today SCA Forest is one of few forestry companies in the northern Sweden with an integrated forest wood supply and industry. The goals of the company are to supply their own industries with wood and to manage the resources of the forest through a long-term perspective with satisfactory profitability.

Tillämpning av utvärdering inom operativt förbättringsarbete

In the fall of 2014 a literature review and a scientific study of the topic; "... in the extent to which companies in the industry applies the evaluation of continuous improvement? was conducted at Mälardalen University. These studies are the foundation of this thesis.A strategic improvement is often divided into smaller steps of improvements at each hierarchical level from the top down through the organization. But if there is no response system that can confirm the results of these improvements back through the organization it is very hard to see if the improvements really are improvements or just changes and a waste of resources.
