Klassisia variaatio-ongelmia

2017

Tämä tutkielma käsittelee variaatiolaskentaa. Variaatiolaskenta on saanut alkunsa matemaattisesta analyysistä 1700-luvun vaihteessa Johann Bernoullin esittämän Brachistochrone-ongelman vaikutuksesta. Tätä matematiikan alaa voidaan pitää yleistyksenä analyysin ongelmaan funktioiden ääriarvopisteiden löytämisestä. Reaaliarvoisten funktioiden sijaan variaatiolaskenta käsittelee funktionaaleja. Funktionaalit ovat kuvauksia funktioavaruudesta reaaliluvuille. Funktionaaleilla mallinnetaan ongelmaa, johon variaatiolaskennalla etsitään ratkaisu. Variaatiolaskenta keskittyykin funktion, jolla funktionaali saa suurimman tai pienimmän arvonsa, etsimiseen. Yksinkertaisin esimerkki on kahden pisteen, P1…

"Valloittakaa meidät, tämä on elämänne tilaisuus!" : kriittinen media-analyysi Suomen huippumalli haussa -sarjasta

2011

Tutkimuksen tarkoituksena oli kuvailla ja tulkita sitä, millainen ideologinen tausta Suomen huippumalli haussa -ohjelmalla on. Aineistona tutkimuksessa käytettiin vuoden 2010 keväällä esitettyjen ohjelman kolmannen tuotantokauden jaksoja, joita oli yhteensä kymmenen. Lisäksi tutkimuksessa oli tarkoitus tarkastella, miten valtasuhteita ja ideologisuutta tuotetaan ohjelmassa, sekä pohtia sitä, kuka tai mikä kyseisistä valinnoista hyötyy. Tuloksia tarkasteltiin myös laajemmasta sosiokulttuurisesta näkökulmasta. Tutkimus on luonteeltaan laadullinen ja analyysin näkökulmaksi valittiin kriittinen diskurssianalyysi. Diskurssi ymmärretään tässä tutkimuksessa kielenkäytön tavaksi, joka on kulttuuris…

Interference Estimation in IEEE 802.11 Networks

2010

This article describes a technique for distinguishing and quantifying medium access control (MAC) and physical layer (PHY) interference in error-prone 802.11 networks. This technique, is fully distributed, allowing each station to estimate interference individually. The estimator is based on an extended Kalman filter coupled to a mechanism for revealing abrupt changes in state. The network state is a vector of two components, representing PHY interference, expressed in terms of channel-error rate, and MAC interference. Two distinct state models are considered. When PHY interference can be assumed to be constant for all stations, network congestion is expressed by the number of competing ter…

Inference of Spatiotemporal Processes over Graphs via Kernel Kriged Kalman Filtering

2018

Inference of space-time signals evolving over graphs emerges naturally in a number of network science related applications. A frequently encountered challenge pertains to reconstructing such dynamic processes given their values over a subset of vertices and time instants. The present paper develops a graph-aware kernel-based kriged Kalman filtering approach that leverages the spatio-temporal dynamics to allow for efficient online reconstruction, while also coping with dynamically evolving network topologies. Laplacian kernels are employed to perform kriging over the graph when spatial second-order statistics are unknown, as is often the case. Numerical tests with synthetic and real data ill…

Weakly interacting dark matter in walking technicolor theories

2010

Several lines of evidence support the existence of the dark matter in the Universe. In the light of the present observations the particle dark matter, and in particular the WIMP scenario is a very promising alternative to solve the dark matter problem. In this context recent minimal walking techicolor model motivated dark matter models have been studied. The minimal walking techinicolor and the minimal extension of it, which can successfully provide a dynamical origin for the electroweak symmetry breaking as well as the unification of the standard model coupling constants, gives rise to natural dark matter candidates such as fourth family heavy neutrinos and SU(2) adjoint matter. A general …

Real-time data processing in the ALICE High Level Trigger at the LHC

2019

At the Large Hadron Collider at CERN in Geneva, Switzerland, atomic nuclei are collided at ultra-relativistic energies. Many final-state particles are produced in each collision and their properties are measured by the ALICE detector. The detector signals induced by the produced particles are digitized leading to data rates that are in excess of 48 GB/$s$. The ALICE High Level Trigger (HLT) system pioneered the use of FPGA- and GPU-based algorithms to reconstruct charged-particle trajectories and reduce the data size in real time. The results of the reconstruction of the collision events, available online, are used for high level data quality and detector-performance monitoring and real-tim…

No Difference in Penetrance between Truncating and Missense/Aberrant Splicing Pathogenic Variants in MLH1 and MSH2: A Prospective Lynch Syndrome Data…

2021

Background. Lynch syndrome is the most common genetic predisposition for hereditary cancer. Carriers of pathogenic changes in mismatch repair (MMR) genes have an increased risk of developing colorectal (CRC), endometrial, ovarian, urinary tract, prostate, and other cancers, depending on which gene is malfunctioning. In Lynch syndrome, differences in cancer incidence (penetrance) according to the gene involved have led to the stratification of cancer surveillance. By contrast, any differences in penetrance determined by the type of pathogenic variant remain unknown. Objective. To determine cumulative incidences of cancer in carriers of truncating and missense or aberrant splicing pathogenic …
