Lebesgue points via the Poincar inequality

We show that in a Q-doubling space （X, d, μ）, Q 〉 1, which satisfies a chain condition, if we have a Q-Poincare inequality for a pair of functions （u, g） where g ∈ LQ（X）, then u has Lebesgue points 7-th-a.e. for h（t） = log1-Q-c（1/t）. We also discuss how the existence of Lebesgue points follows for u ∈ W1,Q（x） where （X, d, μ） is a complete Q-doubling space supporting a Q-Poincar; inequality for Q 〉 1.

Traces of weighted function spaces: Dyadic norms and Whitney extensions

引用

Science China Mathematics 2017年第11期60卷 1981-2010页

作者： koskela Pekka SOTO Tomas WANG Zhuang Department of Mathematics and Statistics University of Jyvskyl

The trace spaces of Sobolev spaces and related fractional smoothness spaces have been an active area of research since the work of Nikolskii, Aronszajn, Slobodetskii, Babich and Gagliardo among others in the 1950's. In this paper, we review the literature concerning such results for a variety of weighted smoothness spaces. For this purpose, we present a characterization of the trace spaces(of fractional order of smoothness),based on integral averages on dyadic cubes, which is well-adapted to extending functions using the Whitney extension operator.

Instantaneous foveated preview for progressive Monte Carlo rendering

引用

Computational Visual Media 2018年第3期4卷 267-276页

作者： Matias K. koskela Kalle V. Immonen Timo T. Viitanen Pekka O. Jaaskelainen Joonas I. Multanen Jarmo H. Takala Tampere University of Technology Tampere 33720Finland.

Progressive rendering, for example Monte Carlo rendering of 360° content for virtual reality headsets, is a time-consuming task. If the 3D artist notices an error while previewing the rendering, they must return to editing mode, make the required changes, and restart rendering. We propose the use of eye-tracking-based optimization to significantly speed up previewing of the artist＇s points of interest. The speed of the preview is further improved by sampling with a distribution that closely follows the experimentally measured visual acuity of the human eye, unlike the piecewise linear models used in previous work. In a comprehensive user study, the perceived eonvergence of our proposed method was 10 times faster than that of a conventional preview, and often appeared to be instantaneous. In addition, the participants rated the method to have only marginally more artifacts in areas where it had to start rendering from scratch, compared to conventional rendering methods that had already generated image content in those areas.

Impact of Heat Load Location and Strength on Air Flow Pattern with a Passive Chilled Beam System

Impact of Heat Load Location and Strength on Air Flow Patter...

The First International Conference on Building Energy and Environment

作者： Risto Kosonen Pekka Saarinen Alex Hole Hannu koskela Halton Oy Finnish Institute of Occupational Health Arup

A chilled beam is a source of natural convection, creating a flow of cold air directly into the occupied zone. Experiments have been conducted in a mock up of an office room to study the air velocities in the occupied spaces. In addition, velocity profiles of a passive beam are registered with underneath heat loads when the cool and warm air flows interact. Experimental laboratory study shows that the underneath heat gains, even when no upward plume is generated and the dummy only affects as a flow obstacle, have a significant effect on the velocity profile. Furthermore in an actual occupied office environment, the thermal plumes and the supply air diffuser mix effectively the whole air volume. The maximum air velocity measured was still below 0.25 m/s with the high heat gain of 164 W/m2. The results demonstrate that a simplified analysis of an undisturbed convection flow can not accurately describe air movement and draught risk.

Acute and Persistent Post-Craniotomy Pain: A Prospective 6-Month Follow-Up Questionnaire Study

Open Journal of Anesthesiology 2023年第6期13卷 119-133页

Jääskeläinen Timo Koponen Jari Halonen Tadeusz Musialowicz Department of Anesthesia and Intensive Care Medicine Kuopio University Hospital Kuopio Finland Department of Neurosurgery of Neuro Centre Unit Kuopio University Hospital Kuopio Finland Department of Anesthesia and Intensive Care Medicine North Karelia Central Hospital Joensuu Finland Heart Center Department Kuopio University Hospital Kuopio Finland

Introduction: The incidence of acute pain after craniotomy differs remarkably in previous studies, and the prevalence of persistent pain is not precisely known. We conducted 6-month follow-up surveys on the incidence and intensity of acute and persistent pain after elective craniotomy. Methods: We carried out a prospective cohort study via a series of structured questionnaires to record acute pain intensity preoperatively and postoperatively, and the incidence of persistent pain 3 and 6 months after a craniotomy in a tertiary care center. Patients scheduled for elective craniotomy were interviewed the day before surgery, postoperatively before discharge from the hospital, and 3 and 6 months after surgery. Pain was assessed on a numeric rating scale (0 - 10) at rest and movement, as well as expectations of pain before surgery, efficacy of pain therapy, and satisfaction with pain treatment. The incidence of adverse events, sleep time and interruptions caused by pain, different pain types, and drugs used for pain treatment were also recorded. Results: A total of 152 patients were enrolled in the study and completed the preoperative questionnaire;123 (81%) completed postoperative questionnaire and 108 (72%) completed the 3- and 6-month follow-ups. The average pain score at the time of the postoperative questionnaire was moderate, 4 at rest and 5 upon movement. The percentage of patients experiencing mild pain at rest and upon movement was 52% and 49%, and moderate pain was 15% and 16%, respectively. Severe postoperative pain was detected in 5% and 8% of patients at rest and upon movement, respectively. Three months after surgery, 6% of patients reported mild pain at rest, 3% moderate pain at rest, and 1% severe pain at rest. Persistent mild and moderate pain at rest after 6 months was reported by 3% and 1% of patients, respectively. The most common adverse events were postoperative nausea and vomiting (11%) and abdominal discomfort (8%). During postoperative pain treatm
