Predicting dynamic fuel oil consumption on ships with automated machine learning

This study demonstrates a method for predicting the dynamic fuel consumption on board ships using automated machine learning algorithms, fed only with data for larger time intervals from 12 hours up to 96 hours. The machine learning algorithm trained on dynamic data from shorter time intervals of the engine features together with longer time interval data for the fuel consumption. To give the oper

Domain formation and self-sustained oscillations in quantum cascade lasers

Abstract: We study oscillations in quantum cascade lasers due to traveling electric field domains, which are observed both in simulations and experiments. These oscillations occur in a range of negative differential resistance and we clarify the condition determining whether the boundary between domains of different electric field can become stationary. Graphical abstract: [Figure not available: s

Impact of ischaemic heart disease severity and age on risk of cardiovascular outcome in diabetes patients in Sweden : A nationwide observational study

Objectives To compare short-term cardiovascular (CV) outcome in type 2 diabetes (T2D) patients without ischaemic heart disease (IHD), with IHD but no prior myocardial infarction (MI), and those with prior MI; and assess the impact on risk of age when initiating first-time glucose-lowering drug (GLD). Design Cohort study linking morbidity, mortality and medication data from Swedish national registr

Development of a vibroacoustic stochastic finite element prediction tool for a CLT floor

Low frequency impact sound insulation is a challenging task in wooden buildings. Low frequency prediction tools are needed to access the dynamic behavior of a wooden floor in an early design phase to ultimately reduce the low frequency impact noise. However, due to the complexity of wood and different structural details, accurate vibration predictions of wood structures are difficult to attain. Me

Impacts of extreme climate conditions due to climate change on the energy system design and operation

Extreme climate events occur more frequently and stronger in the future due to climate change. Maintaining the energy security during extreme conditions is essential to reduce the impacts of extreme climate and avoid disasters. Resilient design of the energy system to resist against extreme climate events are investigated considering four scenarios, namely, typical demand (TD), extreme demand (ED)

IEEE Std. P1687.1: Access to IEEE Std. 1687 via UART

The IEEE Std. P1687.1 is exploring alternatives to IEEE Std. 1149.1 test access port for accessing IEEE Std. 1687 scan networks of instruments. In this paper, we investigate the use of universal asynchronous receiver-transmitter (UART) to access IEEE Std. 1687 networks. We have developed a protocol to describe scan-data transported over UART and a hardware component to translate (retarget) informa

Antiparasitic metabolites from hyptis brevipes, a tacana medicinal plant

A bioassay screening against protozoa parasites of several Tacana medicinal plants gave Hyptis brevipes (Id'ene eidhue), traditionally used as decoction for intestinal parasites, as the most active extract. In this work we did a bioguided isolation of active constituents found in leaves. Structure elucidation was carried out by NMR spectroscopy and MS spectrometry analyses. Active constituents sho

The gracilis tendon autograft is a safe choice for orthopedic reconstructive procedures : A consecutive case series studying the effects of tendon harvesting

Background: The gracilis tendon is commonly used as an autograft to reconstruct torn tendons or ligaments in many parts of the body. Little is known about the subjective and functional outcome after gracilis tendon harvest. The aim of this study was to evaluate the outcome of the donor leg in patients undergoing such surgery. Methods: Patients with chronic acromioclavicular joint dislocations unde

Boredom and homelessness : A scoping review

Background: Emerging literature suggests that boredom is a frequent problem experienced by homeless persons that may influence their health and well-being. Purpose: The range and breadth of literature exploring boredom among homeless persons is unknown. We initiated this study to fill this gap in existing literature. Method: Using the method advanced by Arksey and O’Malley (2005), and furthered by

Consequences of planetary migration on the minor bodies of the early solar system

Pebble accretion is an efficient mechanism that is able to build up the core of the giant planets within the lifetime of the protoplanetary disc gas-phase. The core grows via this process until the protoplanet reaches its pebble isolation mass and starts to accrete gas. During the growth, the protoplanet undergoes a rapid, large-scale, inward migration due to the interactions with the gaseous prot

The antibiotic challenge : Justifications for antibiotic usage in the world of medicine

This chapter is a micro-sociological exploration of the justifications that Danish general practitioners adopt to support antibiotic usage in their clinical practices. Based on qualitative in-depth interviews with 21 general practitioners in Denmark, the chapter looks upon the clinic as a particular social world (a justificatory regime) in which different antibiotic treatment strategies are qualif

Glucocorticoid-resistant B cell acute lymphoblastic leukemia displays receptor tyrosine kinase activation

The response of childhood acute lymphoblastic leukemia (ALL) to dexamethasone predicts the long-term remission outcome. To explore the mechanisms of dexamethasone resistance in B cell ALL (B-ALL), we generated dexamethasone-resistant clones by prolonged treatment with dexamethasone. Using RNA-sequencing and high-throughput screening, we found that dexamethasone-resistant cells are dependent on rec

Evaluation of the Lund deep geothermal exploration project in the Romeleåsen Fault Zone, South Sweden : a case study

The bedrock of Skåne, the southernmost province of Sweden, has been targeted for geothermal feasibility studies since the late 1970s. An exploration project concerning the geothermal potential in the Romeleåsen Fault Zone was launched outside the town of Lund in 2001. Besides geophysical imaging of the thrust fault zone, the investigations included drilling and investigations of a 3701.8-m-deep e

Differing impact of clinical factors on the risk of fracture in younger and older women in the general population and an osteoporosis clinic population

Summary: This study assesses the impact of risk factors for fracture in women aged 80+ and 60–79. The results suggest that risk assessment which fits younger women may not be suited for the 80+ strata as many common risk factors are less predictive in the older compared to the younger cohort. Purpose: This study assesses whether the impact of classical risk factors for fracture due to osteoporosis

Multiple-Input Multiple-Output Model Predictive Control of a Diesel Engine

Traditionally, diesel engine control has had to rely on indirect feedback variables and empirical open-loop maps because direct measurements of the variables representing high-level objectives, such as emissions, have not been available in production engines. With new sensors being developed, the opportunity opens to design the controller directly based on high-level objectives. In this paper, we

What is it with education that make many critics leave their role as an informed researcher and argue on the basis of personal opinions?

In this paper, we have analyzed a nationwide debate following the introduction of an individual meritsystem for educational development. When reforms are aimed towards research, even the toughestdiscussions can most often be resolved when arguments are backed by evidence. Not surprisingly, as this goes hand in hand with the language and mindset of the receivers in the researchcommunity. But, when
