BackgroundPostzygotic isolation in the form of reduced viability and/or fertility of hybrids may help maintain species boundaries in the face of interspecific gene flow. Past hybridization events between house sparrows (Passer domesticus) and Spanish sparrows (P. hispaniolensis) have given rise to a homoploid hybrid species, the Italian sparrow (P. italiae). Although genetic incompatibilities are

Purchasing on the part of a building construction company involves actors inside and outside the organization. These actors are driven by different motives that influence purchasing decisions in different situations. An explicit framework that assists in understanding the different purchasing situations would be of benefit to companies and researchers.

Time-domain spectroscopy encompasses a wide range of techniques, such as Fourier-transform infrared, pump-probe, Fourier-transform Raman, and two-dimensional electronic spectroscopies. These methods enable various applications, such as molecule characterization, excited state dynamics studies, or spectral classification. Typically, these techniques rarely use sampling schemes that exploit the prio

An important performance measure of a plant is the plant-availability. The higher availability the better, since a high availability implies a possibility for a large production volume and thereby an increased profit for the company. One way of increasing the plant-availability is by eliminating, or minimizing the effect of disturbances. The cause of a disturbance can be personnel, material or equ

One-dimensional propagation of transient EM-waves in periodic media is studied. The media are periodic in the direction of propagation and can be of finite or infinite length. Wave propagators, that map a transient field from one point in the medium to another, are introduced. A number of useful relations for the propagators are presented. Some of these relations are used in the determination of e

Neural networks learn knowledge from data. For a monolithic structure, this knowledge can be easily used but not isolated. The many degrees of freedom while learning make knowledge extraction a computationally intensive process as the representation is not unique. Where existing knowledge is inserted to initialize the network for training, the effect becomes subsequently randomized within the solu

Every year about 15 million people are injured in traffic, 500,000 of these fatally. Developing countries are badly affected. During the worst years of the war in Nicaragua, more people died in traffic accidents than as a direct result of the war. Transport system and infrastructure have developed rapidly in developing countries, while little has been achieved in preventing accidents or lessening

This report describes the design and development of new concepts for pan, tilt and rotate functionality in fixed domes at Axis Communications. The aim of the master’s thesis was to generate a concept that are smaller and less expensive compared to the solutions today. Remote pan, tilt and rotate is a unique feature which makes it possible to remotely control a camera during installation and redire

Researchers, from various academic departments, are increasingly undertaking studies of phenomena by way of practices considered to be within the sub-field of emotional geography. Emotional geographers, in an attempt to imbue research with the intensely subjective experiences of events and spaces, seek to uncover feelings by way of emotions, yet cautiously avoids the non-representational by workin

This thesis represents results from a numerical study of the ventilation system in the control room in the Swedish submarine A26. This thesis's primary focus is to study and examine the performance and efficiency of the current ventilation system. The ventilation system is very critical and crucial in enclosed environments. Many factors and parameters are affected by the installed system. In c
