Vacation Queueing Models : Theory and Applications
A classical queueing model consists of three parts - arrival process, service process, and queue discipline. However, a vacation queueing model has an additional part - the vacation process which is governed by a vacation policy - that can be characterized by three aspects: 1) vacation start-up rule; 2) vacation termination rule, and 3) vacation duration distribution. Hence, vacation queueing models are an extension of classical queueing theory.
Stress and immunity
Many people have experienced the connection between stress and getting sick. Colds, influenza, herpes and allergies seem worse when we are severely stressed at work or in the home. Others are never sick until they go on vacation (that is, after the stress is over), and then they spend the whole time fighting the virus. Because of intrinsic connections like these, many researchers are today exploring whether (and how) stress and illness are actually linked. One specific focus of this research is to study the effects of stress on the immune systems; after all, if stress affects immunity, that would be one way in which stress could contribute to illness. The function of the immune system is to protect us from organisms that cause disease, and from other materials that would be harmful to the body. Cells of the immune system (i.e., white blood cells) circulate throughout the body in the blood and are also located in various organs, including the bone marrow, thymus, lymph nodes and spleen. There are a number of different kinds of white blood cells, but the most important in this context are lymphocytes.
Motivic Homotopy Theory : Lectures at a Summer School in Nordfjordeid, Norway, August 2002
This book is based on lectures given at a summer school held in Nordfjordeid on the Norwegian west coast in August 2002. In the little town with the sp- tacular surroundings where Sophus Lie was born in 1842, the municipality, in collaboration with the mathematics departments at the universities, has established the “Sophus Lie conference center”. The purpose is to help or- nizing conferences and summer schools at a local boarding school during its summer vacation, and the algebraists and algebraic geometers in Norway had already organized such summer schools for a number of years. In 2002 a joint project with the algebraic topologists was proposed.
