In many industrial applications the communication in a distributed control system is done over layered synchronous or asynchronous control buses. In this paper we consider the type of delays and control deterioration that can be obtained due to the communication delays. The main source of the delays considered in this paper is the sample-induced delays caused by the multirate sampling in the commu
This article covers a method to make the description of theforce-slip curve generated by the brush tire model more flexible. A calibration factor is applied to make the slope more or less convex. The main use is in car applications where road friction estimation is a major issue. If the real tire characteristic differs from the model there will be a bias in the estimation and a higher brake force
Pioneering studies performed over the past few decades demonstrate links between epigenetics and type 2 diabetes mellitus (T2DM), the metabolic disorder with the most rapidly increasing prevalence in the world. Importantly, these studies identified epigenetic modifications, including altered DNA methylation, in pancreatic islets, adipose tissue, skeletal muscle and the liver from individuals with
Energy metabolism dyshomeostasis is associated with multiple health problems. For example, abundant epidemiological data show that obesity and overweight increase the risk of cardiometabolic diseases and early mortality. Type 2 diabetes (T2D), characterized by chronically elevated blood glucose, is also associated with debilitating complications, high healthcare costs and mortality, with cardiovas
Leucine-rich repeats and immunoglobulin-like domains (LRIG) proteins have been implicated as regulators of growth factor signaling; however, the possible redundancy among mammalian LRIG1, LRIG2, and LRIG3 has hindered detailed elucidation of their physiological functions. Here, we show that Lrig-null mouse embryonic fibroblasts (MEFs) are deficient in adipogenesis and bone morphogenetic protein (B
T-cell lymphoma (TCL) is a rare group of malignancies and one of the important aims in this thesis has been to broaden the general knowledge of TCL with descriptive patient data. Main focus has been to examine prognosticfactors for overall survival (OS) and progression-free survival (PFS), and to evaluate different treatment approaches and follow-up (FU) after treatment.The purpose of the first st
The intensifying effects of climate change are becoming one of the main threats to cultural heritage, posing risks of degradation or destruction. Climate change is bringing complexity and uncertainty to ensuring the resilience of cultural heritage, and among risk mitigation measures digitalisation is regarded as a promising tool. However, the infrastructure required for the digitalisation process
HYPOTHESIS: Self-assembling molecular structures responding to light stimulus are appealing for applications as sensing and drug delivery. Supramolecular nanotubes have a relevant potential in nanotechnology as they can be used to encapsulate different loads like drugs, biological macromolecules, and nanomaterials. In addition, they are suitable elements for novel supracolloidal materials. Structu
Although the overall mortality in cancer is steadily decreasing, major groups of patients still respond poorly to available treatments. The key clinical challenge addressed in the present thesis work relates to the inherent adaptive capacity of glioblastoma (GBM) tumors, resulting in treatment resistance and dismal prognosis. GBM represents the most common and lethal primary CNS tumor in adults. T
Stability problems associated with robot control with obstacle avoidance are analysed. Obstacle avoidance algorithms based on potential function are revised to accomplish stable re-design. A stability proof using Lyapunov theory and passivity theory is provided for the re-designed obstacle avoidance algorithm. The paper presents a modification of potential functions for obstacle avoidance aiming t
The impact of climate change on the deterioration of reinforced concrete elements have been frequently highlighted as worthy of investigation. This article addresses this important issue by presenting a time-variant reliability analysis to assess the effect of climate change on four limit states; the probabilities of corrosion initiation, crack initiation, severe cracking, and failure of a simply
Research suggests that until recently families in history could only avoid episodes of poverty if they put money aside. By helping to smooth consumption over the family life cycle, finance could prevent impoverishment, and is also likely to have had an effect on family life. Saving may have influenced cohabitation structures and the timing and incidence of birth, marriage, and death. That families
Cities across the world are increasingly labelling themselves as smart in one way or another. At the same time, this smartness appears amorphous or invisible in its built urban environment. Critical researchers writing on the smart city regularly express confusion or exasperation about precisely the difficulty to locate the smart in the city. Visibility of the smart city is not a given. This artic
Hur hänger Aktie-SM 1979 ihop med nyliberalismens framväxt i Sverige? Vilken roll spelade kokainet för Sigmund Freuds syn på normalitet? Hur har månen påverkat människan genom historien? Vad fick Mary Wollstonecraft att på resa genom ett kargt Norden omvärdera sin syn på revolutioner? Och vad kan en hästslaktare i 1800-talets Stockholm säga oss om människans paradoxala förhållande till djuren?Bild
Worldwide, and especially in Western civilizations, most of the staple diets contain high amounts of fat and refined carbohydrates, leading to an increasing number of obese individuals. In addition to inducing metabolic disorders, energy dense food intake has been suggested to impair brain functions such as cognition and mood control. Here we demonstrate an impaired memory function already 3 days
Det här dokumentet ger lokala politiker och tjänstemän ett processorienterat verktyg för att stärka förankringen (integreringen) av ekosystembaserad klimatanpassning i relevanta sektorer av kommunal verksamhet. Guiden presenterar systematiskt de nivåer och områden där förankring av ekosystembaserad klimatanpassning är viktigt, och möjliggör på så sätt planering och bedömning av åtgärder. Det övergThis guideline offers local government officers and local politicians process‐oriented assistance for integrating ecosystem‐based adaptation within relevant sectors of municipal administration with the aim of fostering sustainable urban development. It is thus an instrument to support leadership of this integration process. The levels and areas where integration of ecosystem‐based adaptation isrel
I denna forskningsöversikt kartläggs svenskproducerad och kvalitetsgranskad forskning om svensk forskarutbildning i syfte att illustrera forskningsfältets fysiska och vetenskapliga formering 2000–2020. Databasen Swepub användes för att identifiera licentiatavhandlingar, doktorsavhandlingar och refereegranskade artiklar som sedan analyserades med deskriptiv statistik och tematisk analys. Fältets fyIn this scoping review we map Swedish research on Swedish doctoral education in order to illustrate the physical and scientific configuration of the field from 2000 to 2020. The database Swepub was used to identify licentiate theses, doctoral theses, and peer reviewed articles. Subsequently the material was analysed through descriptive statistics and thematic analysis.
