This paper presents a suggested methodology based on virtual reality (VR) technology that enables people with cognitive disabilities to communicate their knowledge and experiences of public transport systems. The users interacted with the VR system by verbally describing their actions to the person controlling the VR system and/or pointing with a laser pointer while seated in front of three screen
Abstract in UndeterminedContextThe key for effective problem prevention is detecting the causes of a problem that has occurred. Root cause analysis (RCA) is a structured investigation of the problem to identify which underlying causes need to be fixed. The RCA method consists of three steps: target problem detection, root cause detection, and corrective action innovation. Its results can help with
Abstract in UndeterminedRoot cause analysis (RCA) is a structured investigation of a problem to detect the causes that need to be prevented. We applied ARCA, an RCA method, to target problems of four medium-sized software companies and collected 648 causes of software engineering problems. Thereafter, we applied grounded theory to the causes to study their types and related process areas. We detec
Radio based localization is an active research topic with a wide range of applications. In this paper, we focus on localization of a radio receiver equipped with an inertial measurement unit. The localization is performed while simultaneously constructing a map of the small scale fading pattern in the local radio environment. The map in our case is a ray-trace-based multipath channel model. This s
During outdoor storage of large quantities of wood fuels, hydrocarbons are emitted into air in gas phase and leached out into the ground by precipitation. To investigate to what extent these emissions have environmental or health effects, sampling has been done on wood chip piles in an existing terminal storage situated in the south of Sweden, north east of Växjö. Sampling was done by solid phase
Gerhard Schurz [2001, Journal for General Philosophy of Science, 32, 65-107] has proposed to reconstruct auxiliary hypothesis addition, e.g., postulation of Neptune to immunize Newtonian mechanics, with concepts from non-monotonous inference to avoid the retention of false predictions that are among the consequence-set of the deductive model. However, the non-monotonous reconstruction retains the
An important part of responsible business practices is compliance with the law. This article details what actually happens when the laws of the host country fail to ensure adequate protection. The focus here is on land dispossession and loss of livelihood in relation to a gold mine project in central Ghana. How is it that a well-known international company—Newmont—with its own corporate social res
Asisted living (AL) technologies, enabled by technical advances such as the advent of the Internet of Things, are increasingly gaining importance in our aging society. This article discusses the potential of future high-accuracy localization systems as a key component of AL applications. Accurate location information can be tremendously useful to realize, e.g., behavioral monitoring, fall detectio
The difficulty of predicting returns has recently motivated researchers to start looking for tests that are either more powerful or robust to more features of the data. Unfortunately, the way that these tests work typically involves trading robustness for power or vice versa. The current paper takes this as its starting point to develop a new panel-based approach to predictability that is both rob
Young people with psychiatric disabilities may require support in structuring their everyday life. To learn more about the relevance of day centres in this respect, this study aimed to examine the experiences of young people with psychiatric disabilities. A particular focus was on the perceptions of meaningful occupation when visiting day centres, their reasons for not choosing this option when gi
NURBS (Non-uniform rational B-splines) surfaces are the standard freeform representation in Computer- Aided Design (CAD) applications. Rendering NURBS surfaces accurately while they are interactively manipulated and deformed is a challenging task. In order to achieve it, the elimination from pipeline in early stages of back-facing surfaces or surface pieces is a key advantage. Furthermore, an effe
Reliable connectivity between vehicles is a requirement for efficient overtaking warning systems. We investigate the 6 GHz propagation channel between oncoming vehicles with five different types of large obstructing vehicles in a poor scattering environment. The presented channel gains emphasize the advantages of different antenna positions and the difference between a straight road and curved roa
People form part of the biosphere - the biosphere being the whole intertwined network of life on Earth. While there is convergence on the need for societal change for just sustainability and a healthy biosphere, the pathways to achieve these transformations remain relatively unclear. Through legal interpretation, conceptual and thematic analysis of academic and grey literature, we seek to answer t
Purpose: The survival rate of breast cancer for women in low- and middle-income countries is poor compared with that in high-income countries. Point-of-care ultrasound (POCUS) combined with deep learning could potentially be a suitable solution enabling early detection of breast cancer. We aim to improve a classification network dedicated to classifying POCUS images by comparing different techniqu
Reliable maritime communication systems are essential for both safety-critical operations and emerging applications such as autonomous shipping, remote pilotage, and drone-assisted search and rescue. These scenarios demand ultra-reliable, low-latency wireless connectivity, where communication outages are unacceptable. Equally important is the need for dependable positioning systems. In situations
For a labor market, such as the one for economists, an employer often faces the diffi- culty of distinguishing attainable from unattainable candidates. Offers, rejections and the recruiting process overall is costly, and participants of the market need to choose who to pursue wisely. EconMatch is a site aiming to provide suggestions on what candidate is the best to pursue for a university, based o
Food is a fundamental human need – a physical requirement for survival. At the current historical juncture, the global food system is entangled in a web of neoliberal capitalist exchange relations and suffers from heavy dependence on fossil energy inputs. Today’s agro-industrial complex, which has evolved jointly with fossil capitalism and is organized according to its principles, is firmly entren
Voluntary Sector Organisation Public Partnerships (IOP) are a new collaboration form for voluntary and public organisations aiming to give financial support to a welfare service provided by the voluntary actor. The aim of this study is to examine to what extent a voluntary organisation can be independent in order to be able to advocate as an IOP-participant. The object of study is the Red Cross an
I denna uppsats undersöks begreppet tjänst och vad som utgör en tjänst tillhörande informationssamhället samt en tjänst på transportområdet. Utredningen görs med anledning av att en spansk domare fattat beslut om att inhämta ett förhandsavgörande där EU-domstolen ska undersöka huruvida tjänsten Uber utgör en tjänst tillhörande informationssamhället eller istället utgör ren transportverksamhet. FThe main purpose of this thesis is to examine the notion of services and consider what constitutes an information society service and a service in the transport sector. In a preliminary ruling, yet to be decided by the European Court of Justice, a Spanish judge has recently queried whether the service provided by Uber should be considered an “information society service” or merely a transport serv
There is a new area being developed by the river in Gothenburg, called “Frihamnen”. Social sustainability and social mix are two main concerns when developing new neighborhoods and residents in the area, and the goal is to create Frihamnen for everyone. Frihamnen has been studied as a case. Document studies and interviews has been used and the purpose is to see how the goal of creating a mixed are
