"This monograph describes the Reaction Wheel Pendulum, the newest inverted-pendulum-like device for control education and research. We discuss the history and background of the reaction wheel pendulum and other similar experimental devices. We develop mathematical models of the reaction wheel pendulum in depth, including linear and nonlinear models, and models of the sensors and actuators that are

Ofärd är en roman som utspelar sig i mitten av 600-talet. Handlingen är förlagd till Sverige och Frankerriket. Intrigen är fiktion, men skildringen av miljöer och personer vilar på historisk och arkeologisk forskning.

Artikeln behandlar reglerna om automatisk förlängning av konsumentavtal med utgångspunkt från Högsta domstolens avgörande i NJA 2012 s. 776.

Information technology is a central phenomenon in modern society. It is widely used in a variety of settings and commercial firms use it for a variety of purposes. It could be an Internet application, a manufacturing system, office support software, electronic data interchange or something else, applied in order to create economic benefits through improvements of operative work tasks and business

Capacity development for disaster risk reduction is an important process to substantially reduce disaster losses, which threaten sustainable development and the achievement of the Millennium Development Goals. This paper presents a theoretical framework with seven elements for capacity development for disaster risk reduction that has been tested in practise with noteworthy results. The seven eleme

Popular Abstract in Swedish Deformerbara speglar som används i teleskop är förhållandevis små med en diameter på 10-30 cm, med undantag av ett fåtal. Den största deformerbara spegeln som är integrerad i ett teleskop idag, har en diameter på 911 mm och återfinns i Large Binocular Telescope. I designen för E-ELT har en deformerbar spegel med en diameter på dryga 2 m inkluderats och GMT har ett antalIt is attractive to integrate a large deformable mirror for adaptive optics into an astronomical telescope rather than using relay optics within an auxiliary instrument. However, the resulting large deformable mirror can be expensive, particularly for extremely large telescopes. We have pursued a low-cost approach using force actuators connected to the back of the deformable mirror through suction

Kring en kritik av senare års ekonomiska globalisering har under 2000-talet samlats en rad organisationer och rörelser, för att gemensamt protestera mot såväl internationella och övernationella organ som nationella regeringar och den politik som dessa står för. Förutom som en kritik mot globaliseringens former, kan protesterna samtidigt ses som ett globalt fenomen i sig. Genom transnationella nätv

Music, Life and the Joy of Playing: Music Teachers on Teaching, Artistic Development and the Challenges of Music Studies is based on interviews with twelve musicians/teachers at the Malmö Academy of Music, conducted by Karin Johansson. The twelve interviewees offer a picture of life-long learning during which the joy and desire to make music is the chief driving force. A teacher at an academy of m

In cold climates, all user requirements for footwear (insulation, waterproofing, vapour permeability, drying, etc.) cannot be met easily due to their conflicting nature. Defining user conditions is important. Cold may be roughly divided into the three ranges (>+5; +5 to –10;

Introduction to the book

This chapter outlines an innovative and collaborative design research project that connects New Zealand SME manufacturers with advanced design thinking about affective design. This project was developed and implemented by the centre for affective design research (Affect) at Massey University. Design researchers and five NZ companies have collaborated to foster ‘design-for-desirability’ thinking an

Braided convolutional codes (BCCs) are a class of spatially coupled turbo-like codes with a structure that is similar to product codes or generalized LDPC codes. We derive explicit input/output transfer functions of the component convolutional decoders for the binary erasure channel (BEC). These are then used to formulate exact density evolution equations for blockwise BCCs under belief propagatio

Methods for monitoring seepage and detecting internal erosion are essential for the safety evaluation of embankment dams. Internal erosion is one of the major reasons for embankment dam failures, and there are several tenths of thousands of large embankment dams in the world. Internal erosion is progressing inside the dam, and is sometimes difficult to detect by conventional methods. Therefore, th
