We consider the problem of admission control to an M/M/1 queue under periodic observations with average cost criterion. The admission controller receives the system state information every ø :th second and can accordingly adjust the acceptance probability for customers who arrive before the next state information update instance. For a period of ø seconds, the cost is a linear function of the time

In this theses I have focused on how the mechanisms of species interactions affect community structure. It is well known that certain species may have a particularly strong influence on the structure of a community. What is not fully understood is how to characterize these species that have such a strong impact on community structure. In my work, I have work tried to find out what makes such speci

"It is not the eyes that fool you, it’s not the ears that can’t hear It’s the darling conceptions of your time that makes you feel this way" Detta sjunger 1600-talsastronomen Galileo Galilei i denna artikel i FRAMTIDSBOKEN, och artikeln kretsar, precis som alla sex ingående artiklar, kring konceptuella problem knutna till vår tid och ett samhälle som är mer och mer uppkopplat. Dessa dilemman är

In this paper we investigate MIMO systems where faster-than-Nyquist (FTN) signaling is used as modulation. On the AWGN channel, the main characteristic of FTN is the so called Mazo limit; it is possible to signal considerably faster than conventional without loss in minimum Euclidean distance. We show that MIMO-FTN systems inherit this property from the AWGN-FTN systems. Moreover, not only does it

Hur upplever vi våra sjukdomar och hur verkar medicinen bäst? Hur påverkar själva upplevelserna våra reaktioner på läkemedel? Boken är helt inriktad på den vardagliga användningen av läkemedel och berör hela fältet av placebo, säkerhet, följsamhet och bieffekter, allt med utgångspunkt från den berörda människan och hennes möjligheter att svara på grundfrågan ”Hjälper medicinen?”, nu och framöver.

This book connects two linguistic phenomena, modality and subordinators, so that both are seen in a new light, each adding to the understanding of the other. It argues that general subordinators (or complementizers) denote propositional modality (otherwise expressed by moods such as the indicative-subjunctive and epistemic-evidential modal markers). The book explores the hypothesis both on a cross

A Low Weber water spray subjected to an air cross flow has been investigated. The spray is characterized by low liquid injection velocity, producing a column that is broken up by aerodynamic forces from the oncoming air.PIV and PDA have been used to quantify both the continuous and dispersed phases. Long range microscopy has been used to characterize the column breakup process. It has been shown t
