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

The deterministic approach for the prediction of noise in electrical machines is generally based on the use of FEM/BEM models. Mechanical and electromagnetic properties included in these models, such as the damping or the BH curve, are difficult to estimate, compromising the accuracy in the noise prediction. Simulations showed that a 10% increase in the saturated part of the BH curve results in an

In this study a dynamic model of a solid oxide fuel cell (SOFC) system has been developed. The work has been conducted in a cooperation between the Department of Energy Sciences, Lund University, and Mode Ion AB using the Modelica language and the Dymola modeling and simulation tool. Modelica is an equation based, object oriented modeling language, which promotes flexibility and reuse of code. The

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

The aim of the work presented in this thesis was to improve ethanol formation from xylose in recombinant Saccharomyces cerevisiae strains. This was achieved by decreasing the xylitol by-product formation. Gre3p is the major xylose-reducing enzyme in S. cerevisiae. Ypr1p, Gcy1p and the protein encoded by YJR096w also have the ability to reduce xylose in cell extracts. Furthermore, Gre3p, Ypr1p, Gc

The article analyses in a historical perspective how ideas of Europe are discussed in Baltic intellectual, political and scholarly debates, and how the Baltic republics are positioned in these debates.

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

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,

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

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

Discussion of transparency and indexes of corruption and their effect on the growing anti-corruption movement. Trust in numbers may lead to opacity rather than transparency

This report has been written at the request of The Swedish National Committee for Psychology at the Swedish Royal Academy of Sciences and it provides an account of the external research funding at the six large university departments of psychology in Sweden during the years 1995, 1997, 1999 and 2001. First, an overview of the six departments is given with respect to the amount of research funding,

Popular Abstract in Swedish I inledningen till avhandlingen görs tre viktiga antaganden som sedan kommer att ligga till grund för all vidare argumentering; (i) för det första görs ett (i sammanhanget kontroversiellt) ontologiskt antagande. Det antas att troper (dvs. partikulära egenskaper) existerar; (ii) för det andra antas (återigen kontroversiellt) att troper är det enda som existerar (åtminstoThe treatise attempts to approach and deal with some of the most fundamental problems facing anyone who wishes to uphold some version of the so-called theory of tropes. Three assumptions serve as a basis for the investigation: (i) tropes (i.e. particular properties) exist, (ii) only tropes exist (that is, tropes are the only basic or fundamental kinds of entities), and (iii) a one-category trope-t
