This report addresses the related problems of trajectory generation and time-optimal path tracking with online obstacle avoidance. We consider the class of four-wheeled vehicles with independent steering and driving on each wheel, also referred to as pseudo-omnidirectional vehicles. Appropriate approximations of the dynamic model enable a convex reformulation of the path-tracking problem. Using th
The development of models that provide accurate spatio-temporal predictions of ambient air pollution at small spatial scales is of great importance for the assessment of potential health effects of air pollution. Here we present a spatio-temporal framework that predicts ambient air pollution by combining data from several different monitoring networks and deterministic air pollution model(s) with
In this paper we discuss new adaptive proposal strategies for sequential Monte Carlo algorithms—also known as particle filters—relying on criteria evaluating the quality of the proposed particles. The choice of the proposal distribution is a major concern and can dramatically influence the quality of the estimates. Thus, we show how the long-used coefficient of variation (suggested by Kong et al.
We present a newly constructed spectrometer for negative--ion/positive--ion coincidence spectroscopy of gaseous samples. The instrument consists of two time--of--flight ion spectrometers and a magnetic momentum filter for deflection of electrons. The instrument can measure double and triple coincidences between mass--resolved negative and positive ions with high detection efficiency. First results
Objectives To develop evidence-based European League Against Rheumatism (EULAR) recommendations for vaccination in patients with autoimmune inflammatory rheumatic diseases (AIIRD). Methods A EULAR task force was composed of experts representing 11 European countries, consisting of eight rheumatologists, four clinical immunologists, one rheumatologist/clinical immunologist, one infectious disease p
Reading utilises at least two neural pathways. The temporal lexical route visually maps whole words to their lexical entries, whilst the nonlexical route decodes words phonologically via parietal cortex. Readers typically employ the lexical route for familiar words, but poor comprehension plus precocity at mechanically 'sounding out' words suggests that differences might exist in autism. Combined
OBJECTIVE: Employment rates are significantly lower among individuals with arthritis compared to a general population. There is, however, limited research about how men with arthritis perceive their ability to maintain working. The aim of this study was thus to explore their perception of this. PARTICIPANTS: Nine employed men with arthritis were purposively sampled. METHODS: Interviews were perfor
Background: Over time, methods for the development of clinical decision support (CDS) systems have evolved from interpretable and easy-to-use scoring systems to very complex and non-interpretable mathematical models. In order to accomplish effective decision support, CDS systems should provide information on how the model arrives at a certain decision. To address the issue of incompatibility betwe
Room acoustics, as a branch of architectural acoustics, has got more and more attention nowadays. One of the aims of the room acoustics is to develop different method to evaluate the acoustic performance of the rooms and to address human acoustic comfort needs. Meanwhile, the process of reverberation plays an important role in room acoustics, and it is also an evaluation standard of evaluating roo
Syfte: Syftet var att undersöka om vårdnadshavares skattning av sina barns expressiva ordförråd samt barnens resultat på ett formigenkänningstest vid 20–24 månader kan förutsäga barnens expressiva och impressiva ordförråd 6–7 månader senare. Föreliggande studie är en uppföljning av en undersökning av Strahl (2017) som vid tillfälle 1 inhämtat data avseende formigenkänningsförmåga samt expressivt o
Antalet personer som lever med en kronisk sjukdom ökar, detta som en konsekvens av bland annat en snabbt ökande äldre befolkning. Kroniska sjukdomar orsakar inte bara mänskligt lidande, utan är också en ekonomisk börda för samhället. För att lindra lidandet och minska kostnaderna kopplade till kroniska sjukdomar kan användandet av digitala hälsotjänster vara en möjlighet. För närvarande är förväntThe amount of people living with chronic diseases is increasing. Chronic diseases do not only induce human suffering, it is also an economic burden on society. To ease the suffering and reduce the costs connected to chronic diseases, the usage of digital health services might be a possibility. Currently, the expectations on such services are high, but not met. To better meet the expectations, this
Preservatives and non-ionic surfactants are frequently used in biological drugs for multiple dosage. However, the most commonly used surfactants and preservatives are known to be incompatible with each other, leading to the solution becoming turbid due to precipitation. This study aims to investigate at which concentration regions precipitation occurs between non-ionic surfactants (polysorbate
Determining how proteins interact with each other to form complexes is very important for understanding both disease and cellular functions, but experimentally determining the structures of these complexes is both tedious and slow, which is why a great number of protein-protein docking algorithms have been developed to predict them. To this day, conformational changes in protein backbones have bee
The purpose of this paper is to analyse the phenomenon of country branch’s communication alignment between the corporate and country-specifics, based on the example of the German development organisation GIZ and its country branch GIZ Pakistan. This includes how the communication strategy and concepts are aligned and how the alignment is negotiated and decided. The analysis is guided by the interp
The thesis is to develop a 3D printer that easily and conveniently can print with recycled plastic such as PET bottles, plastic packaging and much more. The printer will be designed according to the needs of a developing country. The idea is not to create an additive manufacturing factory but an effective manufacturing tool for the locals in the less developed parts of the country. The printer can
As digital cameras become cheaper and better, computers more powerful, and robots more abundant the merging of these three techniques also becomes more common and capable. The combination of these techniques is often inspired by the human visual system and often strives to give machines the same capabilities that humans already have, such as object identification, navigation, limb coordination, an
Importance: Breast cancer screening guidelines acknowledge the need for earlier screening for women at increased risk but provide limited guidance for women with a family history of breast cancer. A risk-adapted starting age of screening for relatives of patients with breast cancer may help supplement current screening guidelines. Objective: To identify the risk-adapted starting age of breast canc
