Gestaltningsfloran : en brygga mellan hortikultur och biotopgestaltning

Contemporary plant design can be examined by how it relates to two extremes - Nature and Art. This idea is explained by Noel Kingsbury in the book The Dynamic Landscape where he places designers and their projects on a gradient (Kingsbury, 2004). Nature, one of the extremes can be represented by a dynamic, species-rich plant design with native species and with nature as the ideal. The other extreme - Art implies a more static view on plant design. Here, the designs consist of colourful flowers, exotic species and cultivars with double flowers.

Sensorfusion för ACC-System

Genom att fusionera (sammanföra) data från olika sensorer kan ett resultat uppnås som ger mer än de enskilda sensorerna var för sig. Här utreds vilka sensorer och sensorfusionsmetoder som kan vara aktuella att använda för Scanias adaptiva farthållare (ACC). Den adaptiva farthållaren anpassar det egna fordonets hastighet inte bara till en förinställd hastighet utan även till framförvarande fordons hastighet. Scanias ACC-system använder idag en radar för måldetektering.Det finns ett antal algoritmer och arkitekturer som passar för sensorfusionssystem beroende på nivån hos sensordatan och användningsområdet. Minstakvadratmetoder kan användas då data ska matchas mot en fysisk modell, ofta med lågnivådata.

Programmering av styrutrustning för vridbord vid radarmätplats

Vid kalibrering av en radars antenn placeras radarn på ett vridbord som kan rikta in den mot en mast. På masten sitter ett kors som används som riktpunkt. Huvuduppgiften i examensarbetet var att skriva ett program i National Instruments programmeringsmiljö LabVIEW som kan ställa in vridbordet med en noggrannhet på 0,1 milliradianer. Programmet ska kunna användas som ett DLL (Dynamic-link library) i LabWindows/CVI där ett antal olika funktioner ska kunna anropas för styrning av vridbordet. Eftersom nästan all maskinvara är från National Instruments blev programmet väldigt lätt att skriva.

Obligationsmarknaden och Baselfördragen

Det första Baselfördraget har kritiserats kraftigt för sin okänslighet för låntagares riskattribut. Empiriska undersökningar så som Arak, Corcoran 1996 visar hur låga risker hos kreditvärdiga aktörer passerar ouppmärksammade av banker. Hos obligationsmarknaden premieras dock de låga riskerna vilket speglas i lägre kreditkostnader för de kreditvärdiga aktörer som sökt sig dit. Uppsatsen utreder de förmodade framstegen inom Baselfördragen i deras förmåga att kvantifiera samt prisjustera för kreditrisk. I detta syfte definieras och testas tre kreditprissättningsmodeller.

Att balansera Management Control Systems - En fallstudie av ett litet svenskt IT-företag

This thesis studies the concept of balance in the management control systems (MCS) of a small Swedish company within the IT-sector. The aim is to evaluate the importance of balance and dynamics in MCS and investigate which factors affect them. The frameworks used are Simons (1994) four levers of control, and the five-factor model for balance and dynamics by Mundy (2010). The small IT company - the object of the case study - has grown extensively in the last years and needs to develop more formal MCS without losing efficiency and creativity in their fast-moving industry. The case study reveals that balancing MCS is important also in smaller companies with less formal MCS.

Stegvis förändring för demokratisering i Kina-en möjlighet?

The aim of this essay is to investigate the situation for democracy in China. The study raises two main questions. They are as follows: Are there obstacles to a democratization process in China? and Are there openings when it comes to a gradual change for democratization in China? The theoretical framework consists of Robert A.Dahl´s Polyarchy theory, and in addition , five factors promoting democracy. Also the notion of an MDP-society (a modern, dynamic and pluralistic society) is looked upon.

Nätverkens betydelse för turistdestinationen : en studie av gotländska turistrelaterade nätverk

The tourism industry is growing and with its growth competition between destinations rises. In competition, cooperation and collaboration between tourism operators seem beneficial when creating an attractive and dynamic tourist destination.The purpose of this study is to describe and discuss the significance and influence of tourist related networks at a tourist destination, and therefore this study aims to examine the question: What significance do the tourist related networks have at a tourist destination?This study focuses on seven networks on Gotland that are tourism related, and the representatives of the networks were interviewed in order to get their view on the network and its significance to the destination. The study shows that networks have an important role in creating a unified tourist product of the destination, and in reaching out to the potential visitors through joint destination marketing. The study also shows that the tourism related networks helps to improve the reception of the tourist at a destination and to secure the quality of the tourist destination and its tourist products..

Transferfunktionsmodeller modellering och prognoser av Sjötransportindex

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

Adaptiv varvtalsstyrning vid användning av en lastbils kraftuttag

Med ett växande fokus på ett långsiktigt hållbart samhälle som tar ansvar för miljön strävar fordonstillverkare efter att sänka energiförbrukningen på sina fordon. Detta arbete behandlar hur man kan sänka bränsleförbrukningen för lastbilar med påbyggnader. En påbyggnad kan t.ex. vara en kran, en lastväxlare eller en betongpump. En metod för att sänka energiförbrukningen är att sänka det varvtal som lastbilens dieselmotor arbetar vid.
