Contemporary digital musical instruments allow an abundance of means to generate sound. Although superior to traditional instruments in terms of producing a unique audio-visual act, there is still an unmet need for digital instruments that allow performers to generate sounds through movements in an intuitive manner. One of the key factors for an authentic digital music act is a low latency between
We present a method for augmenting a nominal controller with a peak filter to achieve improved rejection of narrowband disturbances. The method is based on consideration of the open-loop Nyquist curve, which arguably makes it more intuitive and flexible than previous approaches. We also comment on some implementation aspects, and give an application example based on a control problem at a particle
Modern antenna design for communication systems revolves around two extremes: devices, where only a small region is dedicated to antenna design, and base stations, where design space is not shared with other components. Both imply different restrictions on what performance is realizable. In this paper properties of both ends of the spectrum in terms of MIMO performance is investigated. For small a
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: The objective of this review is to assess benefits and harms of postnatal administration of corticosteroids for the management of transient tachypnea of the newborn.
In order to assess the potential of electrical resistivity for imaging gas migration at landfills, two relatively well-known sites - one bioreactor landfill and a conventional landfill - have been monitored successively. A three-dimensional resistivity image could be constructed every two hour on both sites. Meteorological parameters were monitored at the same time, with one measurement taken ever
The problem of planning a trajectory for robots starting in an initial state and reaching a final state in a desired interval of time is tackled. We propose an approach based on model predictive control to solve the problem of point-to-point trajectory generation for a given final time. We discuss various choices of models, objective functions, and constraints for generating trajectories to transf
Background: Numerous different types of variations can occur in DNA and have diverse effects and consequences. The Variation Ontology (VariO) was developed for systematic descriptions of variations and their effects at DNA, RNA and protein levels. Results: VariO use and terms for DNA variations are described in depth. VariO provides systematic names for variation types and detailed descriptions fo
Samverkan har blivit en nyckelterm för att förstå akademins förväntade roll i samhället. Genom samverkansprojekt ska nya värden, lösningar och framgångar skördas. Men hur går detta till i praktiken? Samverkan handlar om relationer, och relationer förändras över tid. Just föränderligheten och brokigheten när det gäller samverkan är viktig att förstå. Vilka är utmaningarna och möjligheterna? Samverk
Purpose: The aim of the study is to investigate associations between socioeconomic and occupational factors and lymphoproliferative (LP) diseases. Methods: We performed a follow-up study on the economically active Swedish population, based on the Swedish Family-Cancer Database. Standardized incidence ratios and 95% confidence intervals were calculated in different social classes and occupations. R
Vacant commercial facilities are an increasing concern in many developed countries. Despitethe low occupancy rates in existing facilities, new commercial facilities that betteraccommodate the needs of modern end-users are constantly developed. In addition to financialconcerns, under-utilized spaces are a great environmental burden, as buildings account forapproximately one third of the global ener
The built environment accounts for 40% of the totalenergy consumption and CO2 emissions in Europe.Furthermore, the majority of environmental impacts ofproperties are generated during the operation phase of thebuilding. Increasing energy efficiency through energymanagement could offer an effective solution to managing theCO2 emissions of a building through its life cycle. Buildingautomation systems
We consider the coupling of the compressible Navier-Stokes equations with the heat equation as a model for cooling processes in steel forming. The semidiscrete coupled system is solved using stiffly stable SDIRK methods of higher order, where on each stage, a fluid-structure interaction problem is solved. textcopyright 2009 American Institute of Physics.
While popular narratives about success in South Africa focus on individual effort, accidents of birth continue to determine life prospects. Inequalities in early childhood development, health, and education narrow the range of possibilities that young people have available to them, and this impacts on their risk appetite, including, through the workings of the maturing brain, a propensity to viole
