We describe our contribution to the SemEval task on Frame-Semantic Structure Extraction. Unlike most previous systems described in literature, ours is based on dependency syntax. We also describe a fully automatic method to add words to the FrameNet lexical database, which gives an improvement in the recall of frame detection.
This paper considers how researchers can best establish a forward trajectory in their work, individually and collectively. The suggestion is sometimes made in academic circles that it is inappropriate to present work that revisits an area previously discussed within the field. While we accept that any published paper should make an original contribution to what is collectively known about a partic
This paper presents a design study aiming to compare a PMSM, EMSM and an SMSM solution in order to rind the most competitive one for the BAS application. The study is mainly based on FE calculations, which are contrasted with the results obtained from a common car alternator. The highlights are efficiency and torque characteristics, and the way they contribute to improve the most important feature
Syftet med denna framställning är att aktivera en diskussion kring öppna och dolda värden i gruppforskning. Med sådana värden avses här explicit eller implicit uttryckta önskvärda tillstånd i grupper. Det kan röra sig om t.ex. "effektivitet", "ideala samverkanssituationer", "demokrati" eller "arbetsgrupp enligt Bion". För att undersöka förekomsten av sådana genomgicks samtliga bidrag av till grupp
This paper presents a novel approach to scheduling communications among concurrent hardware processes mapped onto a "System on a Programmable Chip." Point-to-point, broadcast and multi-cast ommunication types are supported. The algorithm has been prototyped on the Processor-Coupled Polymorphous Fabric for the Altera Excalibur Arm architecture. The communication schedule problem has been specified
Three methods are suggested to identify and quantify flashback and flash forward events based on chemiluminescence recordings of swirling flames. The approaches differ in the procedure to determine the instantaneous flame position. The results revealed that the most robust method is to determine a threshold relative to the instantaneous maximum intensity. Analysis of the complete dataset indicated
In this work we compare channel estimation algorithms for use in an iterative CDMA receiver in a block fading environment. The receiver consists of a soft multiuser data estimator, a bank of single user decoders, and a multiuser channel estimator. The multiuser data estimator is implemented as parallel interference canceler with unconditional post-MMSE filtering (PIC-MMSE) and the decoder is a sof
The paper describes a novel method for self tuning cylinder pressure based heat release computation that is suitable for online usage in e.g. combustion phasing control applications. The method estimates the polytropic exponents and cylinder pressure offsets immediately preceding and succeeding the combustion event respectively using a fast nonlinear least squares method. The polytropic exponent a
The ambition in this thesis is to try out an alternative language for music didaktik relations during music activity in preschool settings. The aim of the study is to describe and to analyze the didaktiks in music activity in preschool settings. The aim of the study is also on research basis to try out concepts that denote and capture the figuration of music activity. The overall research question
This research investigated how the employees of a company experienced a VR-model of an office building that was to be their future work place and how that VR-experience com¬pared with the employees’ experience of the completed building. About two years after the VR-showings the building was completed and the staff had moved into the building. The results for the employees who saw the VR-presentati
This paper investigates the mean square error optimal time-frequency kernel for estimation of the Wigner-Ville spectrum of a certain class of nonstationary processes. The class of locally stationary processes have a simplified covariance structure which facilitates analysis. We give a formula for the optimal kernel in the ambiguity domain and conditions that are sufficient for the optimal time-fre
Control is traditionally applied using periodic sensing and actuation. In some applications, it is beneficial to use instead event based control, to communicate or make a change only when necessary. There are no known general closed form solutions to such event based control problems. We consider stationary event-based control problems with mixed continuous/discrete time dynamics and stochastic di
Calculation of relative humidity and temperature in an early stage of the design process is important to avoid moisture damages in wooden walls. Previous studies show that a sufficient air flow in the air gap behind the façade panel is important to ensure a moisture safe construction. This study investigates if blind WUFI 5.0 calculations with a varied air flow in the air gap behind the façade giv
To find a controller that provides the maximal stability margin to an LTI system under rank-one perturbations is a quasiconvex problem. In the paper, the dual quasiconvex problem is obtained, using the convex duality arguments in the Hardy space H∞. It is shown that the dual problem can be viewed as minimization of a "length" of uncertainties that destabilize the system. Several examples establish
Safe languages like Java provide a much more programmerfriendly environment than the low-level languages in which real-time and embedded software have traditionally been implemented. However, an obstacle for widespread use of Java in control applications has been the predictability and real-time performance of garbage collection, and the cumbersome memory management associated with RTSJ NoHeapReal
The use of test coverage measures (e.g., block coverage) to control the software test process has become an increasingly common practice. This is justified by the assumption that higher test coverage helps achieve higher defect coverage and therefore improves software quality. In practice, data often shows that defect coverage and test coverage grow over time, as additional testing is performed. H
Organ donation is a crucial aspect of healthcare, yet, the number of donors is insufficient to cover the demand for transplant procedures. In the European Union, around 15 people die each day waiting for a life-saving organ. National policies differ greatly among countries, but it is unclear how successful policies affect Deceased Organ Donation when introduced in other settings. This paper explor
