1. 1. CFD and data-driven modeling for safe spillway discharge

   Författare :Shicheng Li; Anders Ansell; James Yang; Robert Boes; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discharge safety; hydraulic design; spillway; discharge capacity; aerator; two-phase flow; air entrainment; energy dissipation; CFD; data-driven modeling; Betongbyggnad; Concrete Structures;

   Sammanfattning : A spillway is a crucial dam structure that regulates water levels and prevents the dam from overtopping. The majority of the dams in the world were constructed before the 1980s. Compared to the current design flood standards, many spillways are undersized, e.g. LÄS MER

3. 2. Numerical simulations of flow discharge and behaviours in spillways

   Författare :Shicheng Li; Anders Ansell; James Yang; Sébastien Erpicum; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spillway; step geometry; discharge prediction; flow behaviour; machine learning; computational fluid dynamics; Utskov; steggeometri; avbördningsuppskattning; flödesbeteende strömningsegenskap; maskininlärning; flödesdynamisk beräkningsanalys numerisk simulering; Betongbyggnad; Concrete Structures;

   Sammanfattning : A spillway is an important component of a dam and serves as a flood release structure. It achieves controlled discharge of water and protects the dam from overtopping. The majority of the hydropower dams were built before the 1980s, and many spillways are undersized in light of the present design flood guidelines. LÄS MER

4. 3. Premature Discharge from Intensive Care with Special Reference to Night-Time Discharge and Capacity Transfers

   Författare :Fredric Parenmark; Sten Walther; Folke Sjöberg; Carl-Johan Wickerts; Mats Fredrikson; Jan Wernerman; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Objectives  Intensive care is an expensive and limited resource, and when a demand supply mismatch between available beds and influx of patients occurs, one temporary measure is to discharge a patient to make room for the new admission. Sometimes the patient is discharged sooner from its original ICU than ideal; i.e. LÄS MER

5. 4. Nutritional status and functional capacity in elderly people with hip fracture

   Författare :Margaretha Bachrach-Lindström; Ingalill Rahm Hallberg; Linköpings universitet; []
   Nyckelord :elderly people; functional capacity; hip fractnre; mental impairment; nutritional status; MEDICINE; MEDICIN;

   Sammanfattning : The aim was to study nutritional status and functional capacity in elderly men and women admitted to hospital with a hip fractnre, and to evaluate the effect of nutritional intervention and surgical method. A total of 176 patients participated in the study. LÄS MER

7. 5. Serum Cholesterol, Lifestyle, Working Capacity and Quality of Life in Patients with Coronary Artery Disease. Experiences from a Hospital-based Secondary Prevention Programme

   Författare :Roland Carlsson; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; work capacity; quality of life; lipid lowering treatment; secondary prevention; lifestyle changes; coronary artery bypass surgery; : Coronary artery disease; myocardial infarction;

   Sammanfattning : Coronary artery diseases (CAD) are main causes of morbidity and hospitalisation in western countries and CAD patients are at considerable risk of suffering further cardiac events. The development and evaluation of secondary prevention programmes therefore an important task. LÄS MER
