Application of the max-min fairness principle in telecommunication network design

The rapid growth of traffic induced by Internet services makes the simple over-provisioning of resources not economical and hence imposes new requirements on the dimensioning methods. Therefore, the problem of network design with the objective of minimizing the cost and at the same time solving the tradeoff between maximizing the service data flows and providing fair treatment of all demands becom

Determination of Low Energy Constants and testing Chiral Perturbation Theory at Next to Next to Leading Order

We present the results of a search for relations between observables that are independent of the Chiral Perturbation Theory (ChPT) Next-to-Next-to-Leading Order (NNLO) Low-Energy Constants (LECs). We have found some relations between observables in $\pi\pi$, $\pi K$ scattering and $K_{l4}$ decay which have been evaluated numerically using the old fit (fit 10 in~\cite{Amoros:2001cp}) of the NLO LEC

A superconducting undulator at the 500 MeV RF-gun driven linac-recirculator at MAX-lab

MAX-lab is replacing its microtron injector with a RF-gun driven 500 MeV recirculator linac (250 MeV linac with one recirculation). The linac will later be equipped with a low emittance laser gun. In this paper, a future installation of a superconducting undulator driven by the recirculator beam is discussed. The undulator is characterised by the emission of spontaneous undulator radiation. The li

Generalized Accelerated Gradient Methods for Distributed MPC Based on Dual Decomposition

We consider distributed model predictive control (DMPC) where a sparse centralized optimization problem without a terminal cost or a terminal constraint set is solved in distributed fashion. Distribution of the optimization algorithm is enabled by dual decomposition. Gradient methods are usually used to solve the dual problem resulting from dual decomposition. However, gradient methods are known f

Control loop timing analysis using TrueTime and Jitterbug

A modern control system is typically implemented as a multitasking software application executing in a real-time operating system. If the computer load is high, the controller will experience delays and jitter, which in turn degrade the control performance. Arguing for an integrated design approach, the paper describes two computer tools for implementation-aware control analysis: TrueTime and Jitt

Conceptualizations of childhood, pedagogy and educational research in the postmodern : A critical interpretation

Over the last fifty years the debate between modernism and postmodernism has surfaced in the disciplines of social sciences. Epistemologically, there is a shift away from the concept of a “found” world, “out there”, objective, knowable and factual, towards a concept of “constructed” worlds, thus problematizing postulates based on the autonomous, stable, unified, essentialized, coherent and integra

Stochastic Reactor Models for Engine Simulations

The aim of the thesis work is the further development of practical engine simulation tools based on Stochastic Reactor Models, SRMs. Novel and efficient implementations were made of a variety of SRMs adapted to different engine types. The models in question are the HCCI-SRM, the TwoZone SI-SRM and the DI-SRM. The specific models developed were incorporated into two different interfaces: DARS-ESSA,

User related assessment of Enhanced Dynamic Pass Predictor (BMW)

The aim of the user related assessment was to study perceived advantages, disadvantages, usefulness, trust, acceptance, willingness to have and pay for the driver assistance system: Enhanced Dynamic Pass Predictor developed by BMW within the framework of the SECONDS subproject. Due to restrictions of driving by naïve drivers in real traffic conditions, assessment activities were limited to a demon

Aviculture : A History

This book discusses the history of aviculture and the cultural extent of keeping and raising birds in captivity for pleasure, companion, ornamental reasons, religious causes or various economic or practical purposes. Since the dawn of mankind, humans have kept birds in captivity. Several species are truly domesticated, while others have simply been bred in captivity for many generations. Today bir
