In this work, we present implementation and experiment of the theory of dynamic force sensing for robotic manipulators, which uses a sensor fusion technique in order to extract the contact force exerted by the end-effector of the manipulator from those measured by a wrist force sensor, which are corrupted by the inertial forces on the end-effector. We propose a new control strategy based on multis
This paper describes a system to create animated 3D scenes of car accidents from reports written in Swedish. The system has been developed using news reports of varying size and complexity. The text-to-scene conversion process consists of two stages. An information extraction module creates a tabular description of the accident and a visual simulator generates and animates the scene. We first des
Our investigation of two EPR and waste management programs in California, U.S. revealed two common features: involvement of the state government is small, and the establishment of concrete recycling/waste management systems is to a large extent left in the hands of entities who have direct responsibility for their implementation. Based on the degree of government involvement, we categorized recycl
During the last decade, a new design of schools with fan assisted natural ventilation has been introduced. Experience and knowledge of this type of ventilation system is therefore needed. The objective of the project is to study the technical and physical conditions required to ensure satisfactory ventilation. The whole project includes analyses of the air flows for different combinations of outdo
Kaposi's sarcoma-associated herpes virus (KSHV) encodes a complement inhibitor named KSHV complement control protein (KCP). We have previously shown that KCP inhibits the human complement system by disrupting the C3 convertase of complement. KCP can accelerate the decay of the classical C3 convertase and it can act as a cofactor for factor I (R), which then cleaves and inactivates C4b or C3b (in t
Mathematical morphology is a powerful means to specify image manipulations; discrete-time cellular neural networks (DT-CNN) is the fast realization. The attractive combination has been sufficiently shown for simple problems but tends to fail in efficiency for more complex ones. The paper introduces a complement and argument swap (CAS) equivalence that allows to solve an image processing problem th
The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with 180-deg turn under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase the blade tip lifetime. Di
The catalyst layer (CL) in polymer electrolyte membrane (PEM) fuel cells is one of the key components regulating the overall performance of the cell. In PEM fuel cells, there are two CLs having identical composition for hydrogen oxidation (HO) and oxygen reduction (OR) reactions. There are four phases inside the CL, namely: carbon, Pt particles, ionomer and voids. In this work, a micro-model of th
This paper reports on the in-context evaluation of an audio-tactile interactive tourist guide - one test was done in a medieval city center, and the other was done at an archaeological site. The activity theory framework was used as a perspective to guide design, field-study and analysis. The evaluation shows that the guide allows users to experience an augmented reality, while keeping the environ
In the EC project, ANNIE (Application of Neural Networks to Integrated Ergonomics) the aim is to develop a human simulation and ergonomic evaluation tool based on a neural network. Recorded movement patterns from subjects, performing tasks in real environments, will train the network. The net will control a mannequin, to perform human-like movements. The human model will be placed in different vir
Even though multisensory environments (MSE) incorporate artifacts and technology to provide sensory stimuli, most of these artifacts are non-interactive. Twenty-four children with profound developmental disabilities from three MSE institutions have been involved in a research study. A handful of interactive design artifacts, which have been developed as a tool for ideation and to enhance the use o
Brain imaging systems are a set of techniques that allow visualizing the regions of the brain that are activated when (emotional) stimuli are presented. Their advantage over traditional methods of measuring emotion, like self-reports is that they leave out response biases. This paper presents what brain imaging measurement can do for emotional design. It also reviews the brain imaging studies that
The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curves surfaces and formation of dust have been studied. Typical are stick slip behaviour and threshold stress levels for formation of dust. The emissions of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, mi
Narrowband radio transmitters like radio amateurs and broadcast radio stations are considered to be a serious problem for high-bitrate data transmission over twisted pairs. Due to its high power level, radio frequency interference (RFI) has the potential of overloading the receiver's analog-to-digital converter (ADC). Once the ADC is in saturation, any countermeasure taken in the digital domain wi
The User Compass Chart (UCC) was used for eliciting middle-age subjects’ experiences of 33 photo-represented easy chairs, including consumer products and chairs designed for nursing-homes as well as institutions in general. The chairs were represented in black and white photos measuring 50 x 50 mm. The vectors used in the chart were most inviting - most repellent and most homelike- most nursing-ho
Force feedback (FF) devices will bring us new ways to interact with computers. The game industry is starting to create sophisticated devices that enable users to feel virtual objects and movements. For people with visual disabilities, this might be even m
Mot bakgrund av USA:s viktiga roll i världspolitiken och speciellt i Mellanöstern och dess konflikter är uppsatsens syfte att undersöka USA:s flerfaldiga politik rörande Israel-Palestinakonflikten mellan 2000–2020. Syftet uppnås genom att besvara frågorna om hur USA har agerat i förhållande till konflikten mellan 2000–2020, vilka motiveringar USA har för sitt agerande samt hur USA:s politik kring Because of the important role that the United States plays in the politics of the world, especially in the Middle East conflicts, the purpose of this study is to analyze the U.S. multiple policy on the Israeli-Palestinian conflict between 2000-2020. The purpose of this study is achieved by answering the questions about how the U.S. has acted in relation to the conflict between 2000–2020, how the U
