This paper is aimed at describing the principles on which are based the current concepts of fire engineering design of steel structures. The first part deals with the design methods for fire safety through the definition of heat exposure and structural models. The second part reviews the state of art in structural fire calculation methods, according to different levelsof assumption.

In this thesis, theoretical models are applied to study some aspects of intrinsically disordered proteins, i.e. proteins that partly or entirely lack a stable native structure. In particular, focus is on peptide binding and aggregation. Knowledge about these mechanisms is important for understanding how proteins interact with each other and how mutations can affect the function and sometimes give

Popular Abstract in Swedish I takt med att fossila bränslen, så som olja och bensin, minskar av jordens resurser så ökar tyvärr samtidigt förbrukningen och därmed efterfrågan på mer bränsle. Detta beror delvis på ökningen av antalet fordon samt på den ökande transportsektorn i världen. De enorma koldioxidutsläppen fortsätter att förstöra vår miljö. I ett kraftfullt försök att minska utsläppen och This thesis focuses on the electromagnetic design of a synchronous machine suited for a belt-driven alternator and starter (BAS) in a micro hybridisation of a mid-size passenger car. The BAS needs to provide a high cranking torque to start the combustion engine, especially in a cool condition where the requirements are highest. Besides the high cranking torque it is desirable to have high power pe

This doctoral dissertation presents the development and digital hardware realization of cardiac event detectors. Implantable medical appliances, as the cardiac pacemaker, have progressed from a life sustaining device to a device that considerably improves life quality for all ages. The number of electronic devices and household appliances in everyday live has an ongoing exponential growth. The

In this paper, we propose to perform remote laser-induced breakdown spectroscopy (LIBS) and Raman imaging of historical monuments to assess the state of a building. The lidar system is equipped with a Nd:YAG pumped optical parametrical oscillator (OPO) system, allowing laser radiation in the wavelength range 220 nm-4 μm. The laser radiation can be sent through a roof-top dome which can steer the r

The Swedish Academy of Sciences was founded in 1739. The article presents and discusses the explicit language policy of the academy and analyzes some aspects of the language and rhetoric of the transactions (in Swedish) of the academy:textual organization, objectivity, rhetorical devices, lexical apparatus, syntactic machinery and techniques of presentation. Special interest is devoted to the tran

Popular Abstract in Swedish I alla tider har människan förundrats och fascinerats över det stillsamma, men samtidigt spektakulära skådespel, som himlen erbjuder en stjärnklar natt. I tusentals år har vi ställt oss frågan: var någonstans i detta gnistrande myller av stjärnor och planeter, kometer och meteorer, passar vi in? Genom århundradena har vår roll i detta skådespel blivit alltmer undanskuffEta Carinae is a super-massive, super-luminous star. It is surrounded by a bipolar nebula, the "Homunculus", and several blobs of ejected gas which are the source of a complex emission-line spectrum. This thesis presents results from spectroscopic investigations of the star and its surroundings, performed with the Space Telescope Imaging Spectrograph (STIS) and the Goddard High Resolution Spectrog

The last decades have seen a strongly increasing use of computers for modeling larger and more complex systems. This has been made possible by a combination of increasing computer power and easy-to-use graphical modeling environments and libraries of components. An important class of systems are described by initial value problems for dynamical systems, and the increasing size and complexity imply
