We present the generalized signal detection theory (GSDT), where familiarity is described by a sparse binomial distribution of binary node activity rather than by normal distribution of familiarity. Items are presented in a distributed representation, where each node receives either noise only, or signal and noise. An old response (i.e., a ‘yes’ response) is made if at least one node receives sign

Objective: The acceptable noise level (ANL) test is used for quantification of the amount of background noise subjects accept when listening to speech. This study investigates Danish hearing-aid users' ANL performance using Danish and non-semantic speech signals, the repeatability of ANL, and the association between ANL and outcome of the international outcome inventory for hearing aids (IOI-HA).

This thesis, based on Philip Pullman’s His Dark Materials trilogy, analyses, from a gender perspective, the depiction of the two main female characters, the main protagonist Lyra and her mother Marisa Coulter, by contemplating their developments throughout the story and by comparing them to the depiction and development of their male counterparts: the second protagonist Will, and Lyra's father

Building materials account for a high percentage of the non-land cost of self-help housing. Few studies, however, have examined the use of building materials by self-help builders and the practicalities of producing and distributing the materials in an alternative manner. This paper discusses the nature of construction by self-help in the intermediate-sized Colombian city of Pereira, focusing in p

Implantation of surgical meshes is a common procedure to increase abdominal wall stability in hernia repair. To improve biocompatibility of the implants, sophisticated in vivo animal models are needed to study inflammation and incorporation of biomaterials. Herein, we have established a new model that allows for the quantitative analysis of host tissue response and vascular ingrowth into surgical

Spectra of far-infrared conductivity contain useful information on charge transport at nanoscopic length scales. However. decrypting the mechanisms and parameters of charge transport from the measured spectra is a complex task in nanostructured systems in particular, the conductivity is strongly influenced by charge carrier interaction with surfaces or interfaces between constituents of the compos

Objectives To ascertain if fetal head position on transabdominal ultrasound is associated with delivery by Cesarean section in nulliparous women with a prolonged first stage of labor. Methods This was a prospective observational study performed at Stavanger University Hospital, Norway, and Addenbrooke's Hospital, Cambridge, UK, between January 2012 and April 2013. Nulliparous pregnant women with a

Solid immersion lenses (SILs) are optically transparent, truncated spheres, brought in contact with a sample to be imaged. The combination of a conventional optical microscope and a SIL results in a highly effective numerical aperture of the imaging system that can improve the resolution. In addition, when imaging high refractive index samples, such as semiconductors, the light collection efficien

The increase in chilled food consumption requires enhanced food safety and quality assurance. Food deteriorating processes are affected by the presence of oxygen, combined with factors such as time and temperature. To slow down deterioration processes and prolong shelf life, traditional packaging methods are being replaced by Modified Atmosphere Packaging (MAP), for example. Oxygen, which is natur

The incorporation of caproic acid in the sn-1 position of phosphatidylcholine (PC) catalyzed by lipase from Rhizopus oryzae was investigated in a water activity-controlled organic medium. The reaction was carried out either as esterification or transesterification. A comparison between these two reaction modes was made with regard to product yield, product purity, reaction time, and byproduct form

New and innovative production equipment can be developed by introducing lightweight materials in modern day automotive industry production lines. The properties of these new materials are expected to result in improved ergonomics, energy savings, increased flexibility and more robust equipment, which in the end will result in enhanced productivity. Carbon composite materials are one such alternati

Plastic is used for an enormous number of products worldwide, one of these being conventional foam. This foam can be found in everything from an office chair to a sponge. To be able to move away from non-renewable sources in hope of protecting our planet we need to find alternatives materials and manufacturing methods for these products. This master thesis will focus on trying to replace conventio

Denna uppsats beskriver vilka kategorier av anställda som är undantagna från anställningsskydd i Sverige och Storbritannien. Fokus för uppsatsen är Storbritanniens ‘employee shareholder’ och Sveriges anställda i en företagsledande eller jämförbar ställning, eftersom dessa två kategorier ger upp delar av sitt anställningsskydd och får någon form av ersättning eller kompensation för detta. UppsatseThis essay describes which categories of employees that are exempted from employment protection in Sweden and the United Kingdom. The focus of the essay will be the UK’s employee shareholders and Sweden’s employees in a managerial or comparable position, since these two categories give up their protection and receive some form of compensation, and/or some other form of protection in return. The es

Bone contains diverse structures. In fast-growing large animals, fibrolamellar bone is formed first and is then gradually replaced by remodelled bone with secondary osteons. Using position-resolved X-ray diffraction and X-ray fluorescence as a 2D multimodal microscopy technique, the nature of biomineral nanocrystals is investigated in bovine bone. Systematic spatial variations are found, for examp

Flying insects frequently navigate through environments of different complexity. In this study, buff-tailed bumblebees (Bombus terrestris L.) were trained to fly along tunnels of different widths, from 60 to 240 cm. In tunnel widths of 60 and 120 cm, bumblebees control their lateral position by balancing the magnitude of translational optic flow experienced in the lateral visual field of each eye.

Isocyanates, aminoisocyanates and amines were quantified from the combustion of 24 different materials or products typically found in buildings. Small-scale combustion experiments were conducted in the cone calorimeter, where generally well-ventilated combustion conditions are attained. Measurements were further made in two different full-scale experiments. Isocyanates and amino-compounds were sa

This paper investigates the moisture dependency of ion diffusion in binary cementitious binders with Portland cement (OPC) in combination with slag or silica fume. Resistivity measurements and calculations with a thermodynamic model, GEMS, were used to assess the unsaturated chloride diffusion coefficient. The results show that the relation between the relative diffusion coefficient and the degree

Further improvements in the clinical care of our most vulnerable patients-preterm infants-are needed. Novel diagnostic and surveillance tools facilitate such advances. The GASMAS technique has shown potential to become a tool to, noninvasively, monitor gas in the lungs of preterm infants, by placing a laser source and a detector on the chest wall skin. It is believed that this technology will beco

Objective: To examine how well ultrasound assessed occipitoposterior (OP) position or high sagittal (HS) position in primiparous women with a prolonged first stage of labor predicts a vaginal delivery and the duration of labor. Design: Prospective observational study. Setting. Stavanger University Hospital, a secondary referral center in Norway. Population. 105 primiparous women with prolonged f
