Performing risk assessments for hierarchical, multi-functional systems, such as a municipality, is an activity that requires input from a multitude of actors. In such systems risk assessments can be performed at many system levels and support different types of decisions. For issues that are constrained to a specific sub-system, such as a municipal department, decisions can be preferably taken at
This paper presents the case study of a newly constructed 1600 m2 kindergarten building in Oslo, Norway. The building has been designed within the framework of the Norwegian Research Council Project LowEx, which aims at engineering solutions to achieve a seasonal coefficient of performance (SCOP) of 6–10 for heating, a seasonal energy efficiency ratio (SEER) of 80–100 for cooling, and an 80% reduc
Background: It is important to quantify a static posture to evaluate the need for and effectiveness of interventions such as physical management, physiotherapy, spinal orthosis or surgical treatment on the alignment of body segments. Motion analysis systems can be used for this purpose, but they are expensive, require a high degree of technical experience and are not easily accessible. A simpler m
The non line-of-sight (NLOS) scenario in urban intersections is critical in terms of traffic safety—a scenario where Vehicle-to-Vehicle (V2V) communication really can make a difference by enabling communication and detection of vehicles around building corners. A few NLOS V2V channel models exist in the literature but they all have some form of limitation, and therefore further research is need. I
Insect migrations are spectacular natural events and resemble a remarkable relocation of biomass between two locations in space. Unlike the well-known migrations of daytime flying butterflies, such as the painted lady (Vanessa cardui) or the monarch butterfly (Danaus plexippus), much less widely known are the migrations of nocturnal moths. These migrations - typically involving billions of moths f
Purpose: Reliable data on familial risks are important for clinical counseling and cancer genetics. However, population-based studies on familial soft tissue tumors are limited, which we will examine. Methods: Adjusted standardized incidence ratios (SIRs), calculated from the nation-wide Swedish Family Cancer Database, were used to measure the familial risk. Results: There were 17 offspring-parent
Quantitative evaluations are valuable in the strive for improvements and asserting quality. However, the field of Command & Control (C2) evaluations are hard to navigate, and it is difficult to find the correct measurement for a specific situation. A comprehensive Scoping Study was made concerning measurements of C2 performance and effectiveness. A lack of an existing appropriate framework for
Objective: To objectively assess anorectal dysfunction following nerve-sparing radical hysterectomy in stage I-II cervical carcinoma patients. Material and Methods: Between 2008 and 2012, 21 patients with primary cervical cancer stage FIGO I-II were enrolled in this prospective study. All women underwent nerve-sparing radical hysterectomy. Anorectal manometry was performed preoperatively and 6 mon

We introduce a Multilevel Monte Carlo method for approximating the transitiondensity for discretely observed multivariate diffusion processes. These areused within a Pseudo-marginal Metropolis-Hastings (PMMH) algorithm to do Bayesianinference on the parameters.The Pedersen representation shows how the transition density can be representedas a conditional expectation, but the corresponding Monte Ca
Electric road systems (ERS) are technologies that allow to charge electric vehicles (EVs) while they are driving. This makes it possible to reduce the installed battery capacity and therefore the weight and cost of the vehicle. However, while the vehicle is charging from the ERS a protective earth connection cannot be ensured, which introduces new isolation challenges in the design of the electric
This European Randomized study of Screening for Prostate Cancer trial follow-up reports that repeated screening reduces the risk of dying from prostate cancer for up to 16 yr.
The need to analyze and understand energy consumption in relation to households' activity patterns is vital for developing policy means that contribute to an energy efficient life and what people would deem as a "good" everyday life. To do this we need to learn more about how energy use is a part of everyday life; this article contributes to that objective. We use the time-geographic diary approac
A considerable part of latency in the baseband of massive multiple-input multiple-output (MIMO) systems is introduced by orthogonal frequency division multiplexing (OFDM) (de)modulation. To address the low-latency demand of massive MIMO systems, a fast Fourier transform (FFT) processor and corresponding reordering scheme are proposed, which reduce the processing latency and reordering latency of O
This study presents a deterministic, lumped model to simulate mesoscale sustainable drainage systems (SuDS) based on a conceptualization of the stormwater control measures (SCMs) making up the system and their influence on the runoff process. The conceptualization mainly relies on parameters that are easily quantifiable based on the physical characteristics of the SCMs. Introducing a nonlinear res
OBJECTIVE: The aim of this study was to test the coherence of a wearable device, an inertial measurement unit (IMU) against the gold standard; also, to test the intra-trial reliability. This study has a cross-sectional design, where measurement of postural sway in the medio-lateral and anterior-posterior directions was performed simultaneously on a force plate and with a IMU called the Snubblomete
The shell condenser is a key component for the underwater vehicles. To study its heat transfer performance and flow characteristics and to design a more efficient structure, a mathematical model is generated to simulate condensation inside the straight and helical channels. The model combines empirical correlations and MATLAB based on an it
Solid waste collection and hauling account for the greater part of the total cost in modern solid waste management systems. In a recent initiative, 3,300 Swedish recycling containers have been fitted with level sensors and wireless communication equipment thereby giving waste collection operators access to real-time information on the status of each container. In a previous study (Johansson, 2006)
