Objective: The aim of this integrative review was to identify facilitators and barriers to patients’ well-being when being cared for in an ICU setting, from the perspective of the patients. Background: To become critically ill and hospitalised in an ICU is a stressful, chaotic event due to the life-threatening condition itself, as well as therapeutic treatments and the environment. A growing body
The formation of the suspected carcinogenic compound acrylamide has become a noticed problem in the heat processing of several types of carbohydrate rich food items. The European Union is currently working to mitigate these levels, where one strategy is to implement a new regulation with benchmark levels for acrylamide in different products. The regulation also includes recommendations on how to r
Title: The Exploring Digital Framework: A Comparative Case Study within the Swedish Manufacturing Industry Author: Daniel Ögren Supervisors: Carl-Johan Asplund (LTH), Jonathan Bergsteen (Triathlon Group), Fredrik Wadsten (Triathlon Group) Background: As new digital technologies and concepts arise, the inherent meaning of digitalization broadens. Consequently, companies experience increasing com
This study aimed to explore which understanding social work professionals have of sugar dating among youth under the age of 18. Furthermore, the purpose of the study was to discover which children engage in sugar dating from the perspective of professionals. We conducted six semi-structured interviews with different social work professionals. The findings from our interviews were analyzed through
Micropollutants in our sources of freshwater is an issue which requires immediate attention. The presence of pharmaceuticals, endocrine disrupting agents, pesticides and other harmful compounds have proven to have impact on the aquatic as well as on human life. Treated wastewater being a major source of ingress of micropollutants into the aquatic environment, the current standards do not stipulate
This thesis explores Artificial Neural Networks (ANNs) for predictive time series classification for Predictive Maintenance (PdM). Time slicing and time shifting are methods used, to enable the models to find features over time, and to predict into the future, respectively. Architectures of increasing complexity are explored for Feed Forward Neural Networks (FFNNs), Convolutional Neural Networks (
A frequently asked question is if owning real estate is a good asset to diversify one's portfolio from the stock market. A common perception is that it favors the portfolio since the two assets are segmentated. Earlier studies came to the conclusion that there is a weak or even negative correlation which is often considered as the basis for this argument. The question is if the stock market an
The climate crisis urges countries around the globe to end their national energy systems’ dependencies on fossil fuels to reduce greenhouse gas emissions. The development of renewable energy sources and its increasing physical interventions into the living space of citizens lead to growing public protests that pose a threat to planned energy infrastructure projects. In response to public protests,
As a foster parent, within the Swedish foster care system, you are granted support and have access to interventions such as educational programs and counselling. Considering this, past research still suggests that a substantial number of foster carers express how these types of interventions can lack a sense of meaningfulness and/or be inadequate. With our research we’ve ventured to better underst
The project explores the application of urban farming in a high-density urban area while considering local characteristics. The site is located on Xiamen Island, China. China has a long history with agriculture since ancient times. However, with the economic growth and urban sprawl from the 1970s, the farming lands are gradually taken by the modern urban blocks. The urban planning did not consid
As a mean of tackling the harsher business environment of today has use of various enterprise resource planning systems (ERPS) increased. It, thus, felt self-evident to focus on what implementation of such new technology would mean and involve both for a whole organization as well as its employees. The construction industry has a long history of and is characterized with project-based work and yet
Thesis purpose: To identify relevant criteria underlying the partner selection process in a leading company in the consumer technology industry, as well as to subsequently analyse the influences which those criteria have on overall outcome. The intention is to draw valid implications for future research as well as for actors in similar market environments. Methodology: The researchers of this pa
Working with innovation has become an essential factor in driving firm success in fast-changing industries like the energy sector. As a result, a considerable amount of previous research has focused on the innovation activities of employees working in R&D or similarly. However, a more recent field of research has focused on studying the employees outside these innovation-specific functions and
The Maxout network is an alternative to artificial neural networks that use fixed activation functions. By adding extra layers of linear nodes the Maxout network is able to learn both the relationship between the hidden nodes and the activation function that they use. The idea was presented as a natural companion to the dropout technique when training large convolutional networks, showing state-of
This case study of the effectiveness of the usage of Japanese role language uses character portrayals from performances by the theatre company Takarazuka Revue to investigate how native Japanese speakers perceive characters solely based upon lexical or grammatical cues in spoken language. With a foundation in Satoshi Kinsui’s description of role language and Christopher Vogler’s character archetyp
When converting electric power from AC to DC, a 12-pulse converter is often used. Unfortunately, the converter creates harmonics superimposed on the DC voltage. These are removed by filters. A passive filter is normally used, but active filters may be added for improved performance. However, the drift in component values due to fluctuations in temperature and the change in load, makes it difficult
MOx sensors are widely used for sensing gases. In this thesis a variable temperature MOx sensor was used to detect graffiti spray paint and differentiate it from other substances using the sensors sensitivity to different gases at different temperatures using machine learning. The machine learning methods Support Vector Machines, k-Nearest Neighbour and neural networks were evaluated and compared.
Landskapet Dalarna i södra centrala Sverige uppvisar en stor variation av kvartärgeologiska sediment och landformer, bildade från deglaciationen i tidig Holocen och senare. Ett speciellt deglaciationsmönster, tillsammans med unika hydrologiska förhållanden, har lämnat utrymme för spekulationer över paleo-miljömässiga förhållandena under det tidiga Holocen. Siljanbassängen, belägen i det södra randThe Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. Lake Siljan is in the southern perimeter of the Siljan impact structure, the most prominent in Europ
There is a shortage of models and analysis methods of fourth generation district heating networks, which are capable of both extracting and depositing heat energy to some thermal network grid. This thesis fills that gap by combining mathematical models of components into a network that is capable of sending heat energy between its nodes. Questions regarding good heating strategies for controlling
Ribonucleotide reductases (RNRs) are important enzymes that convert the building blocks of RNA (NTPs) into building blocks of DNA (dNTPs). dNTPs are used for synthesis of DNA as well as repair of mutated and damaged DNA. These cellular processes are critical to an organism. That is why these processes are found in various organisms. Since these processes are so essential, their allosteric regulati
