Some Acoustic Cues to Human and Machine Estimation of Speaker Age

Two experiments were carried out in order to learn more about the relation between the various acoustic cues to speaker age. The first included listening tests with resynthesized stimuli, and the second comprised automatic estimation of age using the CART (Classification And Regression Trees) technique. In the first experiment, results indicate that human listeners seem to rely more on spectral cu

Taxation of Dividend Income and Economic Growth: The Case of Europe

More recently researchers have turned to analyze how the tax structure, rather than the overall tax level, affects economic performance. For instance, several papers have investigated how taxation on corporate and individual (labor) income influences growth. Taxation of dividend income may also influence growth via its impact on investments and firm behavior. Within the academic community there is

Molecularly Imprinted Polymers at the Nanometric Scale: Synthetic Receptors for Chemical Sensors

In this thesis, polymerisation techniques or deposition methods have been developed permitting the creation of thin molecularly imprinted polymer (MIP) films or patterns and their interfacing with transducer surfaces for biosensor applications. The creation of ultra thin films has been achieved using two different techniques, spin-coating and in-situ polymerization of thin films of monomers conta

Populärvetenskapligt skrivande som mål och medel

Kan populärvetenskapligt skrivande bidra till en bättre ämnesförståelse? Kan det bidra till att öka kvaliteten även på det vetenskapliga skrivandet? Vilken roll spelar lärarens eller handledarens återkoppling under skrivprocessen för lärandet? Hur kan populärvetenskaplig kommunikation integreras i utbildningen? Detta är några av de frågor som denna rundabordsdiskussion kommer att utgå ifrån. Syfte

High-Resolution Measurement of the 4He(g,n) Reaction in the Giant Resonance Region

Popular Abstract in Swedish Kärnan kan ses som en samling nukleoner vilka hålls samman av den starka kraften. Nukleonerna är protoner (p) med laddning +1 och neutroner (n) med laddning 0. Kraften kan beskrivas som ett utbyte av mesoner såsom pioner (pi) vilka förekommer i tre laddningstillstånd pi+, pi- och pi0 (laddning +1, -1 och 0). Inuti kärnan rör sig nukleonerna och utbytesmesonerna vilket gA comprehensive near-threshold 4He(g,n) absolute cross section measurement has been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 20 < Eg < 45 MeV tagged photons (covering the Giant Dipole Resonance energy region) were directed towards a liquid 4He target, and knocked-out neutrons were detected in a pair of 60 cm x 60 cm vetoed NE213A liquid scintilla

Conformational and Dynamical Aspects of Conjugated Polymers and Oligomers of Interest for Photoluminescence

Popular Abstract in Swedish Lysande plast, finns det? Tanken är att att tunn plast-film skall kunna användas som ihoprullbara tunna TV- och datorskärmar, som lysdioder, som mottagare i solceller och som transistorer. Till vardags är förmodligen den vanligaste uppfattningen att plast är ett isolerande material som inte leder ström och som därför heller inte lyser. Faktum är att bara en del av plasTransient absorption laser spectroscopy and resonance Raman spectrscopy have been used to study conjugated polymers and oligomers. To extract more information the measurements have been compared to computer simulations and calculations. In order to obtain a better understanding of the role of conformational disorder in the photophysics of light-emitting, conjugated polymers the ultrafast transient

An Ultra-Low-Power Application-Specific Processor for Compressed Sensing

Compressed sensing (CS) is a universal low-complexity data compression technique for signals that have a sparse representation in some domain. While CS data compression can be done both in the analog- and digital domain, digital implementations are often used on low-power sensor nodes, where an ultra-low-power (ULP) processor carries out the algorithm on Nyquist-rate sampled data. In such systems

Intrauterine blood flow and postnatal development.

Fetal experience forms the basis for postnatal life. This relationship may be obvious in the newborn infant, although it is sometimes not apparent until later in development. One fetal condition with known implications for later life is intrauterine growth restriction (IUGR), which ranges from being an important factor in perinatal mortality to affecting morbidity in adulthood. The process of grow

The Long Lasting Influenza: The Impact of Fetal Stress during the 1918 Influenza Pandemic on Socioeconomic Attainment and Health in Sweden 1968-2012

The observation in the 1940s, that children to mothers having rubella in the first part of the pregnancy experienced elevated health risks in later life led to a growing interest into whether fetal exposure to other – less severe – diseases could cause health problems as well. Epidemiological studies of the fetal origins of later life health that followed found that, while this indeed was the case

Meta-managing: A Study on How Superiors and Subordinates Manage Their Relationship in Everyday Work

In virtually every organization we find formally appointed managers, but nevertheless we tend to condemn the idea of formal hierarchy and celebrate alternative modes of governance that better respect the discretion of employees. This tension, that seemingly surrounds the vertical dimension of contemporary organizations, forms the backdrop of this study which examines how superiors and subordinates

Channel estimation with superimposed pilot sequence

For the purpose of various synchronization tasks (including carrier phase, time, frequency, and frame synchronization), one may add a known pilot sequence, typically a pseudo-noise sequence, to the unknown data sequence. This approach is known as a spread-spectrum pilot technique or as a superimposed pilot sequence technique. In this paper, we apply the superimposed pilot sequence technique for th
