In various conceptual models, the shape parameter (β) of the storage capacity curve, representing the non-linear relationship between relative soil moisture and runoff, determines runoff yield given certain circumstances of rainfall and antecedent soil moisture. In practice, β is typically calibrated for individual catchments and for different purposes, which limits more systematic understanding a
This work presents a study of sensor network calibration from time-difference-of-arrival (TDOA) measurements for cases when the dimensions spanned by the receivers and the transmitters differ. This could for example be if receivers are restricted to a line or plane or if the transmitting objects are moving linearly in space. Such calibration arises in several applications such as calibration of (a
In this article we consider how the operator of an electric power system should activate bids on the regulating power market in order to minimize the expected operation cost. Important characteristics of the problem are reaction times of actors on the regulating market and ramp-rates for production changes in power plants. Neglecting these will in general lead to major underestimation of the opera
Digitalization is an interesting and timely topic which is actively discussed nowadays. Big data & analytics, blockchain, artificial intelligence & robotic process automation are some of the most emerging technologies. This study aims to investigate the perceived benefits and challenges that these technologies bring, in the context of digitalization, to one of the most favorable profession
This paper presents a novel method for 3D human pose and shape estimation from images with sparse views, using joint points and silhouettes, based on a parametric model. Firstly, the parametric model is fitted to the joint points estimated by deep learning-based human pose estimation. Then, we extract the correspondence between the parametric model of pose fitting and silhouettes in 2D and 3D spac
The directive to close the dumpsite in Kisumu, Kenya has made the search for alternative solid waste treatment and disposal technologies urgent. The aim of this research is to support the decision-making process by analyzing multiple socioeconomic and environmental parameters of salient solid waste treatment options. We used multi-criteria analysis to assess and compare anaerobic digestion, sanita
GIS competence is increasing and GIS applications are nowadays used in nearly every area of society. In the perspectives of lifelong learning the needs for GIS knowledge vary widely among target groups depending on previous knowledge, interests, profession, language, age, ability, economic resources and employability. GIS allows us to view, understand, interpret, request, and visualize data in man
Engineers in large-scale software development have to manage large amounts of information, spread across many artifacts. Several researchers have proposed expressing retrieval of trace links among artifacts, i.e. trace recovery, as an Information Retrieval (IR) problem. The objective of this study is to produce a map of work on IR-based trace recovery, with a particular focus on previous evaluatio
Underdrawings and pentimenti-typically revealed through x-ray imaging and infrared reflectography-comprise important evidence about the intermediate states of an artwork and thus the working methods of its creator.(1) To this end, Shahram, Stork and Donoho introduced the De-pict algorithm, which recovers layers of brush strokes in paintings with open brush work where several layers are partially v
This paper presents a novel control architecture for enhanced operator awareness and improved safety in telesurgical systems. We introduce an intermediate layer between the master and slave sides which allows us to modify the slave motion for safety and the force feedback for operator awareness. The intermediate layer is then designed with a performance objective for the specific task at hand. The
We used the nation-wide Swedish Family-Cancer Database to examine the risk for testicular cancer in offspring through parental and sibling probands. Among 0-68-year-old offspring, 4082 patients had testicular cancer in years 1961-2000, among whom 68 (1.67%) had an affected father/brother. Standardized incidence ratios (SIRs) for familial risk were four-fold when a father and nine-fold when a broth
There is a scarcity of rehabilitation methods for people with stress-related disorders that are effective in terms of return to work and reducing sick leave. This chapter describes the Redesigning Daily Occupations (ReDOTM) program for women with stress-related disorders, the development, its main principles, and primary and secondary outcomes. The ReDOTM program, which addresses people’s whole re
Disability due to acute low back pain (ALBP) runs parallel with distress and physical inactivity. If low back pain persists, this may lead to long-term sick leave and chronic back pain. This prospective randomized study evaluated the effect on physical activity and on the course of ALBP of two different treatment advices provided in routine care.
Aims: The aim of this study was to find variables related to positive attitudes to physical education (PE) and strong sense of coherence (SOC) among adolescents. Methods: The study included three parts: seven physical tests; a questionnaire which included ways of living, attitudes to PE, and subjective health, the 13-question version of SOC; and information on every student's grades. The study gro
The present paper will place recent Swedish cinema against the background of the evolving public film policy and support – transnational, national and regional – during the last five decades although with a focus on the last few decades.. The purpose is an attempt to map how certain kinds of films, filmmakers and even locations appear to have been somewhat systematically endorsed or made possible
Knowledge of the current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to its equivalent current distribution on a surface of arbitrary material, ie the radome, is analyzed. The transformation is based on a full vector surface integral representation that relate
The arrangement of plant species within a landscape influences pollination via changes in pollinator movement trajectories and plant–pollinator encounter rates. Yet the combined effects of landscape composition and pollinator traits (especially specialisation) on pollination success remain hard to quantify empirically. We used an individual-based model to explore how landscape and pollinator speci
