Nature provides us with a vast source of inspiration. However, given industrial designers' open-mindedness and inquisitiveness, a surprisingly limited set of nature-derived symbols continues to be popular in this creative discipline. Rather than designing products mimicking nature, it is probably more rewarding designing them based on the natural principles leading to its growth and form. However,

538 vocalisations from three domestic cats were collected and used in a phonetic pilot study in order to test some recording and anal- ysis methods normally used with human speech. Based on auditive analysis, the vocalisations were categorised into five types and analysed for duration and F0. The most common type was a combined murmur and miaow. Similar mean type durations were found in all three

Ongoing work in developing a general structure and a comprehensive components library aiming at modelling liquid-food process lines is presented. The dynamic component models were developed in an object-oriented library structure based on the dynamic modelling language Modelica using the object-oriented graphical tool Dymola. The models were based on fundamental conservation laws and can simulate

Abstract In this thesis, the high temperature superconductors (HTSC) La₂CuO_4+x and Bi₂Sr₂CaCu₂O_8+d and the colossal magnetoresistive (CMR) La_1-xSr_xMnO₃ have been studied by photoelectron spectroscopy. Techniques such as angular resolved photoemission (ARPES), resonant photoemission spectroscopy (RES

In order to accomplish oxidation of alkylaromatic compounds, both cations, which serve as adsorption centers, and oxygen species of suitable bond strength are needed. When compared to partial oxidation, relatively weakly bonded oxygen species are involved in combustion. On the basis of these criteria, using a simple model of the active ensemble, a relationship between reaction rate and bond streng

David Humes (1711-1776) essäer om politik och ekonomi som publiceras i denna volym präglas, liksom hela Humes filosofiska verk, av en strävan att göra filosofi till en i historien och erfarenheten förankrad vetenskap om människan. Enligt Hume – den kanske mest tongivande tänkaren inom den skotska upplysningen – hade filosofin i hög grad kommit att präglas av ogrundade antaganden, föreställningar o

Popular Abstract in Swedish För material på nanoskalan har ytor och gränser större betydelse för materialets egenskaper än de har för storskaliga material. Detta beror på att yt/volymförhållandet är större för material på nanoskalan än för samma material på större skala. Ett fast material där atomerna sitter i en ordnad struktur eller gitter kallas för kristall. En kristall växer när ?nya? atomer Surfaces and interfaces have a special significance to nanotechnology because the surface/volume ratio of nanomaterials is larger than for bulk materials. Therefore, interfaces of nanomaterials are usually more important to the properties of nanomaterials than for larger scale materials. Furthermore, crystal growth occurs at the interfaces between the growing crystals and the supply media. An unde

In the interest of understanding the prospects and restrictions of fuel flexibility in a prototype industrial gas turbine combustor, an experimental study is performed. Methane is used to characterize standard gas turbine operation; in addition a non-standard fuel is explored, generic syngas (67.5 % hydrogen, 22.5 % carbon monoxide and 10 % methane). Both these gases are also investigated after di

I september 1931 tvingades Sverige överge guldmyntfoten. Landet bytte myntfot – från guld till papper – med stabilisering av prisnivån som officiellt mål. Det var första och enda gången ett land försökt sig på något sådant. Sverige anses därigenom ha föregripit den inflationsmålspolitik som sedan 1990-talet bedrivs i ett antal länder, däribland Sverige. I denna bok undersöks hur den nya penning-

Tilläggsisolering bestående av mineralull och puts är en vanlig metod för att förbättra energiprestandan hos flerbostadshus från miljonprogrammet. En annan aktuell, men betydligt mindre utprovad metod, innebär att man tilläggsisolerar fasaden varefter man putsar på en ventilerad skiva. Målsättningen med projektet har varit att undersöka om dessa två tilläggsisoleringssystem har potentialen att kom

This paper looks at process control in the pulp and paper industry from the perspective of pioneering work carried out in the early 1960s. One of the aims of the Billerud-IBM Project was to explore the technical and economical advantages that could be obtained by using a digital computer for control and supervision of a paper machine. The study also explored the features of a digital computer that

For years tools and techniques such as Brainstorming, Mind-Maps and Rich Pictures have been used in both academic and professional practices to assist people with making sense of complex problem spaces. These tools have their supporters and in many cases their uses can be argued to be interchangeable. Seldom however have they been systematically applied in combination in theory or practice. Even t

Purpose of this paper: Logisticians propose changes to improve supply chains, and legal practitioners are doing likewise, but from a tax perspective. Proposals from one domain increasingly have an impact on the other due to e.g. globalisation – but cross-disciplinary knowledge often seems small. Our purpose is to facilitate interaction between the domains by increasing joint understanding o
