This paper describes the optimization of the word lengths in an 8 k-points pipelined FFT processor. The word lengths can be freely chosen since the FFT is implemented as a full custom ASIC. According to the specification, input and output word lengths are 12 bits but improved performance on be achieved by using a longer wordlength internally. Increased wordlength means increased size, both for mem

Resonant tunneling through a single layer of self-assembled quantum dots (QDs) as well as tunneling through two layers of vertically aligned (stacked) dots is investigated. The difference between single and double layers of QDs can be viewed as going from a two-dimensional emitter to a zero-dimensional emitter. By fabricating small-area devices we are able to probe single stacks of quantum dots, r

In this paper, we develop a computational method for model reduction of polynomial dynamical systems. This is achieved using sum of squares relaxations on certain Lyapunov inequalities, which are the nonlinear counterparts of the Lyapunov controllability and observability linear matrix inequalities for linear systems. In our model reduction procedure, we use notions of balanced realization and bal

Popular Abstract in Swedish Det ljus (fotonflöde) som solen sänder ut är grunden för biologiskt liv. Med denna strålning överförs en del av den frigjorda energin från solen till jordens biosfär, där växterna tar upp de energirika fotonerna och omvandlar fotonenergin till kemisk energi. Den kemiska energin lagras sedan som energirika molekyler som transporteras runt i de biologiska systemen för attA low volume and long optical path spectroelectrochemical cell was constructed and tested in a number of applications such as detection of direct electron transfer (DET) between redox enzymes and gold electrodes, determination of the formal potentials of redox centres in proteins and enzymes, as well as mechanistic studies of heterogeneous and intermolecular electron transfer of copper oxidases an

Mira is the perfect purity where the demonic of the master mason has no access. The craftsman’s wife is the embodiment of innocence, the heavenly depiction of mankind as opposed to demonic Manole. “Serenity” and “light” are words that repeatedly occur in her monologue thus suggesting the plenitudine of being she is about to conceive when she would be raising into the light her perfect precious, th

Wireless networked embedded systems are becoming increasingly important in a wide area of technical fields. In this tutorial paper we present recent results on the design of these systems and their use in control applications, that have been developed within the project Reconfigurable Ubiquitous Networked Embedded Systems (RUNES). RUNES is a European Integrated Project with the aim to control comp

Opera improvisation at The Malmö Academy of Music has been a pedagogical and artistic experiment. This is the final account concerning this pedagogical and artistic research project. Singers who are studying classical singing at the bachelor and master programmes of theacademy have participated. The account includes historical and theoretical reflections on the subject and comments on the work in

This thesis considers the numerical study of dispersed two-phase flows.Numerical simulations have been done to investigate the particle trasportation/dispersion effect in turbulent two-phase flows. Both turbulent bubble/water flows and turbulent particle/air flows are studied. Eulerian/Eulerian approach and Eulerian/Lagrangian approachs were both used in the studies. In the Eulerian-Eulerian appro

Uniform circular arrays (UCAs) are naturally suited to provide 360 degrees of coverage in the azimuthal plane. In this paper, we describe a new approach for synthesizing array patterns with guaranteed maximum sidelobe levels for any look direction. The advantage of this approach is that it is computationally efficient which makes it eminently suitable for real-time beamforming and beamsteering app
