This paper presents a symbol time offset estimator for coherent OFDM systems. This estimator exploits both the redundancy in the cyclic prefix and the pilot symbols used for channel estimation. The estimator is robust against frequency offsets and is suitable for use in dispersive channels. We base the estimator on the ML estimator for the AWGN channel. Simulations of an example system indicate a
Non-invasive biological samples benefit studies that investigate rare, elusive, endangered, or dangerous species. Integrating genomic techniques that use non-invasive biological sampling with advances in computational approaches can benefit and inform wildlife conservation and management. Here, we used non-invasive fecal DNA samples to generate low- to medium-coverage genomes (e.g., >90% of the co
Anthropologists of policy have tended to highlight the grand organizational initiatives that are quantitative, standardized and bureaucratic. This article proposes to understand these processes using the term ‘industry’ (as in ‘development industry’ or ‘human rights industry’). Used here, ‘industry’ is not a pejorative but a collection of features, the opposite of which could be called ‘craft’ (lo
In a seminar room at LUX, one of the buildings of the Joint Faculties of Humanities and Theology, a group of PhD students and senior scholars are in deep concentration in front of their computers. It is pin-drop silent in the room until the alarm goes off and everyone starts moving and talking. This is the writing group, an informal and voluntary way of working together in
Organic-inorganic heterostructures play a pivotal role in modern electronic and optoelectronic applications including photodetectors and field effect transistors, as well as in solar energy conversion such as photoelectrodes of dye-sensitized solar cells, photoelectrochemical cells, and in organic photovoltaics. To a large extent, performance of such devices is controlled by charge transfer dynami
Background and purpose — Different marker-selection methods are applied to represent implant and tibial seg-ments in radiostereometric analysis (RSA) studies of total knee arthroplasty (TKA). Either a consistent set of markers throughout subsequent RSA examinations (“consistent-marker method”) is used or all available markers at each follow-up (“all-marker method”). The aim of this secondary analy
This article evaluates the current gaps around the impact of post-manufacturing processes on the product qualities of protein-based biologics, with a focus on user centricity. It includes the evaluation of the regulatory guidance available, describes a collection of scientific literature and case studies to showcase the impact of post-manufacturing stresses on product and dosing solution quality.
Thesis Purpose: The objective of this study is to research how vocal green companies can use green claims in online marketing advertisement text with the aim to recommend ways in which they can positively impact the purchase intention of environmentally friendly fashion products. Methodology: In this quantitative study, the data is analysed through correlations, after which significant difference
Titel Livsstilsboenden - Processen kring att kombinera livsstil, service och boende Författare Elisa De Toro, Helene Tigerström & Liv Åström Handledare Cecilia Fredriksson & Örjan Hallgren Problem Det finns en stor mängd forskning inom områdena service, boende och livsstil. Dock ser vi att det saknas forskning kring hur dessa kan kombineras och hur processen kring detta ser ut. Syfte Syfte
Ekonomiska diskrepanser mellan länder och företag globalt skapar krav och behov för reglering av beviljande av bidrag eller statligt stöd på internationell nivå. I dess frånvaro skulle länder kunna ge vinster till produkter och kringgå konkurrens med otillbörlig förskjutning av varor som skulle ha behövt samma subventioner för att ha en ärbar chans att konkurrera med. Detta skulle bidra till ett öEconomic differences between countries and undertakings on a worldwide scale creates necessities for regulation on the granting of subsidies or State aid at the international level. In its absence, countries would be able to grant benefits to products and circumventing competition with unfairly displacement of goods that would have needed the same subsidies to have a decent chance at competing. Th
Uppsatsen syftar till att bidra till en vidareutveckling av begreppet arbetsmiljö då det skett stora förändringar på arbetsmarknaden. Stressrelaterade sjukdomar och arbetsplats-olyckor blir allt vanligare och det krävs därför ett tydligare humanistiskt och människo-rättsligt perspektiv på begreppet arbetsmiljö. För detta har de risker som kan leda till ar-betsskador undersökts. För att få en bild The essay aims to contribute to the further development of the concept of the working environment as there have been major changes in the labor market. Stress-related diseases and workplace accidents are becoming more common and therefore a clearer humanistic and human rights perspective on the concept of working environment is required. For this, the risks that can lead to work injuries have been
Freeze damage is a common issue in many food items. The cellular dehydration caused by freezing can be prevented through addition of a cryoprotectant. Research has shown that it is possible to improve the freezing tolerance of plant materials by addition of cryoprotectants, which forms hydrogen bonds with water molecules. However, the cryoprotect needs to be in the cell to function. Which is where
Entrepreneurial work and the mental well-being of entrepreneurs often receive positive attention, despite evidence indicating a high prevalence of mental illness among entrepreneurs. This highlights the importance of understanding the stressors arising from entrepreneurial work that can contribute to mental ill-being as well as identifying strategies to mitigate their effects. This knowledge is cr
The rise in entrepreneurial activity over the last 15 years has created space for a nascent industry among the public and private sectors: Business Support Organization (BSO). In the last years, some BSOs have broadened their offer to include for-profit social ventures. Unlike traditional businesses, these ventures try to create a positive social impact while attempting to be economically self-sus
Plastics are amazing materials with outstanding properties that make them very useful and cheap for a wide range of uses. However, their pollution to the environment has become one of the main problems to solve in this century. In this Master Thesis biocomposites from Biofiber Tech are studied. This material is a composite material formed by treated wood fibers and a polymeric matrix. The influen
Tropiska skogar utsätts för mer intensiva och frekventa torkor. Torkor påverkar tillväxt och kollagring i skogen, samt ökar risken för trädödlighet. Det finns flera hypoteser om mekanismerna bakom dödlighet under torka. Två av de vanligaste är något som kallas kolsvält och kavitation. Det är oklart vilken av dessa två mekanismer som inträffar först i tropiska träd under långvarig torka. ExperimentTropical forests experience more intense and frequent droughts. Droughts affect mortality in trees, growth rate and carbon storage in the forest. There are several hypotheses of the mechanisms behind tree mortality during drought. Two of the most common ones are carbon starvation and hydraulic failure. It is unclear which of these mechanisms occur first in tropical trees during long term drought.
Adaptive reuse of existing buildings as a part of the circular economy principle has become a more common approach to promote sustainable development, due to increasing urban densification and environmental concerns. Ventilation systems, as a major contributor to energy use in buildings, often face complete replacement during building reconstruction, despite their potential for extended service li
