The number of applications sharing the same embedded device is increasing dramatically. Very efficient mechanisms (resource managers) for assigning the CPU time to all demanding applications are needed. Unfortunately, existing optimization-based resource managers consume too much resource themselves. In this paper, we address the problem of distributed convergence to fair allocation of CPU resourc
Free space optics is an interesting alternative for telemetry with medical implants, due to the high data bandwidths available at optical frequencies. Especially implanted brain-computer interfaces gives rise to large data sets that needs to be transmitted transcutaneous. In this paper we show that it is possible to establish such a link at near-IR wavelengths using a modulated reflector in the im
There is a debate in Japan which focuses on the lifestyle choices of young Japanese. The elder generation think youth are being selfish and not making a sufficient contribution to society in that they are not conforming to traditional societal expectations. However, it is not so easy to contribute to society when youth have been hit particularly hard by unemployment, changing recruitment practice
The purpose of this thesis is to investigate different formulations of multivariate GARCH models and to apply two of the popular ones – the BEKK- GARCH model and the DCC- GARCH model – in evaluating the volatility of a portfolio of zero-coupon bonds. Multivariate GARCH models are considered as one of the most useful tools for analyzing and forecasting the volatility of time series when volatility
This paper aims to assess the effects of internet usage on bilateral trade volumes. Increasingly companies are conducting business online. If the effect of an increased internet usage on trade is positive then it would be yet another reason for policy makers to invest in the development and expansion of IT infrastructure. Three main models are specified using the fixed effects estimator, includin
Elektroporation är, på Herlevs sjukhus i Danmark, en relativt vanlig metod för att behandla olika typer av hudcancer eller andra cancerformer som utgår från en ytligt belägen mjukvävnad. Behandlingsmetoden använder sig av korta högspänningspulser som överstiger cellmembranets potential, vilket resulterar i att cellmembranets permeabilitet förändras under en kort tid. Är joner eller andra molekylerIntroduction: Calcium is an important ubiquitous second messenger regarding the maintenance of cellular homeostasis, and is therefore tightly regulated. Calcium induces cell death when internalised into cancer cells after permeabilization of the cell membrane by electroporation. It is established that radiation causes damage to the lipids and proteins of the cell membrane; and ionizing radiation a
Acute mesenteric venous thrombosis accounts for up to 20% of all patients with acute mesenteric ischemia in high-income countries and is a very difficult disease to diagnose on clinical grounds. However, owing to the increased availability and evolution of computed tomography in high-income countries, early diagnosis prior to the development of peritonitis is often possible. First-line therapy is
Jordens havsnivå förändras ständigt och dessa förändringar kan ha olika orsaker: i ett längre geologiskt tidsperspektiv är det processer i jordens inre som påverkar havsnivån, men i ett kortare perspektiv spelar till exempel tillväxten och avsmältningen av inlandsisar stor roll. Under kvartärtiden har den sistnämnda processen varit den dominerande vad gäller att påverka havsnivåerna: vid istider hResults from an investigation of relative sea-level changes from c. 11,000 cal. yr BP to the present in the Tasiusaq area, Inner Bredefjord, southwest Greenland, are presented in this thesis. Isolation sequences from two small lakes have been identified using stratigraphic analyses, XRF-scanning, loss on ignition and macrofossil analyses. Macrofossil and bulk samples have been dated in order to e
Evaluation of recommender systems is an actively discussed topic in the recommender system community. However, some aspects of evaluation have received little to no attention, one of them being whether evaluating recommender system algorithms with single-number metrics is sufficient. When presenting results as a single number, the only possible assumption is a stable performance over time regardle
The possibility of a “death from above” cause for biotic crises and extinction events is intriguing, to say the least, but such claims must be supported by reliable and reproducible data, not only impact diagnostic criteria, but also accurate and precise radioisotopic ages of the impact structures/events. To date, only one example of such an impact-related global extinction event is confirmed, at
Background: Many persons with late effects of polio (LEoP) perceive walking limitations in everyday life. A common rating scale to assess walking limitations is the Walking Impact Scale (Walk-12). However, there is limited knowledge about its psychometric properties. Objective: To investigate the psychometric properties of Walk-12 in persons with LEoP. Design: Rasch model analysis of cross-section
The energy gap of correlated Hubbard clusters is well studied for one-dimensional systems using analytical methods and density-matrix-renormalization-group (DMRG) simulations. Beyond 1D, however, exact results are available only for small systems by quantum Monte Carlo. For this reason and, due to the problems of DMRG in simulating 2D and 3D systems, alternative methods such as Green functions com
Sudden cardiac death (SCD) of an athlete is a rare but tragic event and sport activity might play a trigger role in athletes with underlying structural or electrical heart diseases. Preparticipation screenings (PPs) have been conceived for the potential to prevent SCD in young athletes by early identification of cardiac diseases. The European Society of Cardiology protocol for PPs includes history
Families often prefer home care to hospital care, and home-care services for ill children are increasing worldwide with limited knowledge of families’ needs during curative and palliative home care. The aim of this study was to elucidate family members’ lived experience when a sick child received home care from county-based primary healthcare services. A descriptive qualitative design was chosen a
Maillard reaction is an extensively studied, yet unresolved chemical reaction that occurs as a result of application of the heat and during the storage of foods. The formation of advanced glycation end products (AGEs) has been the focus of several investigations recently. These molecules which are formed at the advanced stage of the Maillard reaction, are suspected to be involved in autoimmune dis
The atrioventricular (AV) node plays a central role during atrial fibrillation (AF). We have recently proposed a statistical AV node model defined by parameters characterizing the arrival rate of atrial impulses, the probability of an impulse choosing either one of the dual AV nodal pathways, the refractory periods of the pathways, and the prolongation of refractory periods. All model parameters a
Hypertension (HT) is a worldwide public health issue and an essential risk factor for cardiovascular and cerebrovascular diseases. Obstructive sleep apnea (OSA) is a condition characterized by recurrent episodes of apnea and hypopnea as a consequence of partial or complete obstruction of the upper airways due to anatomic and/or functional disturbances. There is mounting evidence of a relationship
