Large Eddy simulation of a swirling flame response to swirl modulation with impact on combustion stability

A swirl stabilized flame has been studied numerically using Large Eddy Simulation. The response of the flame to a large swirl number modulation has as been determined. Decreasing the swirl number moderately does not destabilize the flame. Decreasing further the swirl number induces a transition from stabilized to a jet flame with increase in the flame fluctuations. Increasing back the swirl restor

Foreign Direct Investments in Southeast Asia

Foreign direct investment has been of large importance in economic growth and global economic integration over the last decades. South East Asia has been part of this development with rapidly increasing inflows of FDI. However, there are large variations over time and between countries in the region as regard to the policies towards FDI, and in actual inflows of FDI. This chapter aims at examining

Känslor i krig. Sensibilitet och emotionella strategier bland svenska officerare 1788–1814

Emotions at War: Sensibility and emotional strategies among Swedish officers, 1788-1814 This thesis studies the relationship between the emotional sufferings of Swedish officers in wartime during the period 1788-1814 and the various mental strategies they employed in order to deal with those sufferings. The study is positioned within the field of research commonly refered to as the history of em

Environmental Effects of Large-scale Desalination Plants in the Middle East

The people bordering the Arabian Gulf, the Mediterranean Sea and the Red Sea rely more and more on seawater desalination for safe water supply. Desalination has advantages and disadvantages which to a large extent depend on the region, location, technology, impact and amount of fresh water production. In this region, some 60% of all desalination capacity is installed. The three regions areas repre

Extracorporeal immunoadsorption

Popular Abstract in Swedish Bakgrund Kroppen har många olika försvarsmekanismer för att skydda sig mot angrepp av olika slag. Bland försvarsmekanismerna i immunförsvaret finns förmågan att bilda antikroppar. Antikroppar, eller immunglobulin, är lösliga protein och består av fyra polypeptidkedjor som hålls samman av svavelbindningar. Dessa kedjor har en variabel ände som ger upphov till molekylensAntibodies are important protein structures in the immunological defence. Occasionally the regulation of the production of these antibodies fails and antibodies directed against self structures are produced in large scale. Antibody production can also complicate or make transfusions and transplantations impossible. Purified protein A from Staphylococcus aureus immobilised to beaded agarose can ads

Improving Access to Evidenced Based Psychological Treatments for Children & Adolescents in the UK

Beginning in 2002, the Department of Health (DoH) n partnership with the National Institute of Clinical Excellence (NICE) began publishing guidelines for the evidenced-based care and treatment of individuals with specific psychiatric disorders. With few exceptions the first-line psychological treatment recommended in all of the guidelines was some form of CBT. The publications of these guidelines

Modeling and Model-based Control of Homogeneous Charge Compression Ignition (HCCI) Engine Dynamics

The Homogeneous Charge Compression Ignition (HCCI) principle holds promise to increase efficiency and to reduce emissions from internal combustion engines. As HCCI combustion lacks direct ignition timing control and auto-ignition depends on the operating condition, control of auto-ignition is necessary. Since auto-ignition of a homogeneous mixture is very sensitive to operating conditions, a fast

A Novel Approach For Gas Turbine Condition Monitoring Combining Cusum Technique And Artificial Neural Network

Investigation of a novel condition monitoring approach, combining artificial neural network (ANN) with a sequential analysis technique, has been reported in this paper. For this purpose operational data from a Siemens SGT600 gas turbine has been employed for the training of an ANN model. This ANN model is subsequently used for the prediction of performance parameters of the gas turbine. Simulated

Improving Cloud Service Resilience using Brownout-Aware Load-Balancing

We focus on improving resilience of cloud services (e.g., e-commerce website), when correlated or cascading failures lead to computing capacity shortage. We study how to extend the classical cloud service architecture composed of a load-balancer and replicas with a recently proposed self-adaptive paradigm called brownout. Such services are able to reduce their capacity requirements by degrading us
