Design of low order approximately linear phase IIR filters

In this paper, a new method for the design of approximately linear phase IIR filters is proposed. This method is based on first designing an asymmetrical FIR filter which is approximately linear phase and then deriving a low order approximately linear phase IIR filter by model reduction techniques.

Anaerobic Digestion of Solid Residues on the Bolivian Altiplano

Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. Most natural organic waste can be used in anaerobic digestion. In developing count

Olympiaskolan och humanistisk bildning som livsstilsprojekt

I tre fallrapporter från forskningsprojektet Framgångsrikt skolledarskap i olika skolkulturer presenteras resultat från omfattande empiriska undersökningar vid tre skolor. I rapporterna beskrivs och problematiseras skolornas respektive kultur: den aktuella gymnasieskolans kunskapskultur, där bildning kommit att bli ett kännetecken; den utvalda f-9-skolans karriärkultur, utsatt för ett kraftfullt f

Modelling of Euroclass Test Results by Means of the Cone Calorimeter

An important part of introduction of the construction productive directive (CPD) is the introduction of the so-called Euroclasses for building products. The Euroclasses define the different fire classes within the European harmonised system. The major fire test method in this system for wall and ceiling linings, the so-called SBI test (EN 13823), is, however, an intermediate fire test and requires

High isolation compact four-port MIMO antenna systems with built-in filters as isolation structure

In this work, we present a built-in filter method to enhance the isolation level between closely packed MIMO antennas. The built-in filter is composed of several slits etched on the ground of the antenna structure. The number and length of slits depend on both the resonance frequency and the structure of the MIMO antenna system. To illustrate its usefulness, two designs of compact planar four-port

Världens frälsare. En text- och tolkarorienterad läsning av några avsnitt och teman i Johannesevangeliet.

Popular Abstract in Swedish Hur framställer Johannesevangeliet Jesus och effekterna av hans gärning med tanke på de universella och inkluderande drag som finns i detta evangelium? Hur förhåller sig dessa inkluderande drag till framställningen i övrigt och till de begränsande och exkluderande drag som också finns där, och hur ska dessa motstridiga drag i evangeliet förklaras? Denna avhandling sökeMy thesis is an analysis of exclusive and inclusive features i the Gospel of John, focusing on the inclusive elements which comprise the world and all its people. These questions are the issue of my thesis: How does the Gospel of John present Jesus and the results of his work with regard to the universal and inclusive features which are in the Gospel? How do they relate to the presentation in gene

Parallelization of MATLAB for Euro50 integrated modeling

MATLAB and its companion product Simulink are commonly used tools insystems modelling and other scientific disciplines. A cross-disciplinaryintegrated MATLAB model is used to study the overall performance of theproposed 50m optical and infrared telescope, Euro50. However thecomputational requirements of this kind of end-to-end simulation of thetelescope's behaviour, exceeds the capability of an in

Review of Language, Music, and the Brain : A Mysterious Relationship.

Reviews the book, Language, Music, and the Brain: A Mysterious Relationship by Michael A. Arbib (2013). For the researcher, or for anyone interested in research using a multidisciplinary approach to the problem of the interrelations between language, music, and the brain, this anthology is at the same time a rich “Handbook of...” and “A Companion to....” As such the book ought to be a priceless re
