In this paper, we discuss research problems for enabling content distribution and supporting real-time interpersonal communication services (e.g. voice and video) over best effort networks with sufficient quality. We take a practical view of content distribution and quality, and this is the reason for the term “sufficient”. We argue that the understanding of quality as perceived by the user is a k
I studien har vi gjort en inventering av inlärnings- och studiestrategifaktorer såsom oro, attityder, koncentration, motivation, studiestöd och tidsplanering bland nybörjarstudenter vid Lunds tekniska högskola (LTH) och studerat hur de förändras under första terminen. Vidare har vi studerat hur självstudietiden påverkar studieresultat och om det finns samband med inlärnings och studiestrategifakto
Abstract in UndeterminedA more or less continuous process of structural change, not least due to a globalizing economy, poses a number of challenges to regions and local communities. However, when firms or whole industries are phasing out, windows of opportunity open up. Empirical analyses of two recent plant closures in Skane point at the importance of retaining existing knowledge bases, and at t
The nuclear physics facility at MAX-lab requires high energy electrons for photonuclear experiments. These electrons are first accelerated in two LINACs that are fed via a SLED system. Arcing in the waveguide structures is currently the limiting factor of the available electron energy. In this report, the implementation of a phase modulation scheme into the injector system is presented. This makes
A series of comparative studies is suggested, focused on perceptions of outrigger canoes, and aimed at an increased understanding of the relationship between social relations, biodiversity, and sustainable development in Oceanic societies on small islands and in coastal areas undergoing rapid cultural change. After a critique of the recent notion that canoe-building in Polynesia developed as a res
Abstract—Denna artikel beskriver hur undervisningen i grundkursen i mekanik för maskinteknik förändrades för att främja djupinlärning hos studenterna och öka examinationsfrekvensen. Strategin var baserad på utökade möjligheter för aktiv inlärning och styrning av inlärning genom att införa förändringar i examinationen. Under kursens gång implementerades kontinuerlig examination med inlämningsuppgif

Clonality is wide-spread among plants, and clonal plants dominate many habitats and include many highly invasive species. Clonal growth incurs both advantages and costs and clonal plants often have reduced sexual reproduction compared to non-clonal plants which could be expected to lower genetic variation and hence evolutionary potential. However, clonal plants have revealed similar levels of gene
Urban living labs (ULLs) are emerging as a form of collective urban governance and experimentation to address sustainability challenges and opportunities created by urbanisation. ULLs have different goals, they are initiated by various actors, and they form different types of partnerships. There is no uniform ULL definition. However, many projects studying and testing living lab methodologies are
Usually the mel-frequency cepstral coefficients (MFCCs) are derived via Hamming windowed DFT spectrum. In this paper, we advocate to use a so-called multitaper method instead. Multitaper methods form a spectrum estimate using multiple window functions and frequency-domain averaging. Multitapers provide a robust spectrum estimate but have not received much attention in speech processing. Our speake
