Improving energy efficiency is a popular means of reducing consumption of energy. When energy efficiency is improved, the marginal cost of energy and energy services will fall, leading to an increase in demand. This is called the rebound effect. This paper explains how the rebound effect arises and what determines the size of it. By examining existing research, it finds that rebound effects are ul
Palaeomagnetic analysis of the Lakhna Dykes (Bastar Craton, India) yields a palaeopole at 36.6 degrees N, 132.8 degrees E, dp=12.4 degrees, dm=15.9 degrees, and the U-Pb zircon age obtained from one of the rhyolitic dykes is 1466.4 +/- 2.6 Ma (MSWD = 0.21, concordia age based on two analyses with identical Pb/U ages), similar to previously published U-Pb ages. Major and trace element analyses of t
Abstract In modern anti-money laundering operations, data analysis plays a vital role. One method of detecting fraudulent data is Benford’s law, which predicts the distribution of the first significant digits in logarithmically distributed data. Deviation from Benford’s law in data where it should be present might indicate manipulated data. We investigate the Chi2 and Kolmogorov-Smirnov tests’ pr
The diurnal hummingbird hawkmoth Macroglossum stellatarum can learn the achromatic (intensity-related) and the chromatic (wavelength-related) aspect of a spectral colour. Free-flying moths learn to discriminate two colours differing in the chromatic aspect of colour fast and with high precision. In contrast, they learn the discrimination of two stimuli differing in the achromatic aspect more slowl
Quick clay has been involved in most serious, large clay slides in Sweden, Norway, and Canada. This paper describes geotechnical and geophysical methods that can be used to locate and map the extent of quick clay formations. Surface resistivity measurements and four different sounding methods have been tested. The results have been compared with sensitivities determined using fall-cone tests. The
Det kan i dagsläget vara svårt att veta hur många som vistas i en byggnad. Detta är problematiskt sett ur räddningstjänstens perspektiv. Om räddningstjänsten under räddningsinsatser vet hur många personer som finns kvar i en byggnad samt var de befinner sig, kan räddningsinsatsen effektiviseras. Utrymningssystem som har kännedom om personers position i en byggnad medger möjlighet att i realtid vägIf during an emergency, the rescue service have knowledge of how many people are left in a building and where they are located, the rescue service’s response could be more effective and reduce the overall risk. Dynamic crowd management is a new way of managing crowd movements during an emergency. For this system to work,sensors capable of tracking people in need of evacuation, is required. In Octo
In this thesis three methods to predict smoke spread thorough small ventilation openings for the CFD field model FDS 5 are evaluated. The methods have been applied to several experiments where smoke spread in to the attic through ventilation openings in the eave have been studied. The obtained result shows that the applied methods are not adequate for heat release rates less than 140 kW. The requi
The European Union actively employs public diplomacy for enhancing visibility and promoting its positive image among the foreign audiences. There is an extensive academic debate concerning the normative and regulatory framework of the EU public diplomacy. While correct, the literature omits the observation of the influence it has on target societies. This thesis is devoted to the illumination of E
Making buildings more sustainable and energy efficient, increases the importance of interoperability of Building Information Modelling (BIM) and Building Energy Modelling (BEM) in the design process. The increasing use of these software calls for finding more efficient ways to work between BIM and BEM. This paper explored different workflow methodologies between BIM and BEM software focused on tim
BACKGROUND: Knee rotation plays an important part in knee kinematics during weight-bearing activities. An external device for measuring knee rotation (the Rottometer) has previously been evaluated for validity by simultaneous measurements of skeletal movements with Roentgen Stereometric Analysis (RSA). The aim of this study was to investigate the reliability of the device. METHOD: The within-day
The aim of this study was to investigate Swedish children's and parents' attitudes and knowledge about human papillomavirus (HPV) vaccination a year after gender-neutral HPV vaccination was introduced in Sweden's national immunization program (NIP). Additional information about HPV and vaccine was provided in the extended immunazation program. In total, 276 parents and 206 children from 22 School
Traditional fire alarms emit a high-frequency sound to alert the occupants of an imminent threat, which may be less appropriate for people who are deaf or hard of hearing. To address this issue, the scientific literature concerning alternative alarm technologies has been reviewed to evaluate their effectiveness in awakening people who are deaf or hard of hearing. The results show that low-frequenc
