I en värld där våra energiresurser snabbt håller på att förbrukas och där miljöpåverkan blir allt större så är det idag viktigare än någonsin för dagens företag att anpassa sig till framtidens energieffektivare samhälle. Att finna energieffektiviserande åtgärder i det dagliga livet kan tyckas enkelt, det är ju bara att släcka lampan och dra ut mobilladdaren efter användning! Att hitta dessa effeThe thesis was conducted due to new laws from the energy agency. The task of this master thesis was to develop a methodology for energy audits, find energy efficiency measures, and then use the methodology to create a detailed mapping of the formalin-, formic acid- and y-polyol plants. The master thesis also resulted in a comprehensive description of the company’s total energy use. To be able to f

This is a case study examines a possible regime shift between the Kyoto Protocol and the Paris Agreement. The study is using a theory consuming approach, with process tracing as the main instrument of analyzation. Using Keohane & Victor’s theory on regime complex, the two different regimes are highlighted: Kyoto and Paris. Applying Abbot, Green and Keohane’s theory on Organizational Ecology, h

Detta examensarbete är ett samarbete mellan Institutionen för Industriell Produktion på Lunds Tekniska Högskola och Trelleborg AB. Målet med arbetet är att analysera polymerhanteringen i Trelleborgs mixing-avdelning utifrån ett lean perspektiv, samt att komma fram till ett nytt förbättrat produktionsflöde. Det nya flödet ska vara effektivare när det kommer till kapacitet, operatörstid, trucktranspThis thesis is a collaborative project between the division of Production and Materials Engineering and Trelleborg AB. The aim of the thesis is to analyse the current pre-batch polymer handling process, assess the current process from a Lean perspective, and provide a new handling process which is more effective in terms of capacity, operator time, forklift transportation and traceability. The cur

Integration of immigrants has become a crucial policy-question in Sweden and Western Europe due to the large numbers of immigrants having settled during the last three decades. Previous research has focused on integration policy outcome by studying the design of different policies and programs. This study addresses the question of how the Somali refugees, which are being better integrated in other

During the last glacial period, proxy records throughout the Northern Hemisphere document a succession of rapid millennial-scale warming events, called Dansgaard-Oeschger (DO) events. A range of different mechanisms has been proposed that can produce similar warming in model experiments; however, the progression and ultimate trigger of the events are still unknown. Because of their fast nature, th

The overall purpose with this thesis has been to consider whether cross-border cooperations funded by Interreg strengthen or undermine the nation-state. A case study has been carried out, where the South Baltic cross-border co-operation has constituted a case. The result is based on material of nineteen interviews with stakeholders from five different countries representing subnational level, nati

Landscape patchiness creates aerodynamic transition zones that affect the exchange of nutrients and pollutants between the atmosphere and vegetation. Using an artificially-generated NaCl aerosol (mass-versus-particle-size distribution with aerodynamic mean particle diameter 1.6 mu m; geometric standard deviation 1.9), we investigated the forest-edge effect on aerosol deposition within a model oak

Palaeoceanographic changes over the last 6800 years are documented in a diatom record from core MD05-2908 from the southern Okinawa Trough. Changes in diatom components are used to reflect variations in the strength of the Kuroshio Current and the influence of coastal waters, and these changes are compared with records of the East Asian summer monsoon, which exerts an important influence on region

It is important to evaluate each step in radiocarbon analysis to ensure that the whole process is as efficient and accurate as possible. Aerosol filter samples contain a myriad of carbonaceous compounds with varying resistance to oxidation. Complete combustion of the sample is thus of great importance to ensure that the graphitized sample is representative of the original filter sample. We have ev

Codes constructed from connected spatially coupled low-density parity-check code (SC-LDPCC) chains are proposed and analyzed. It is demonstrated that connecting coupled chains results in improved iterative decoding performance. The constructed protograph ensembles have better iterative decoding thresholds compared to an individual SC-LDPCC chain and require less computational complexity per bit wh

This discussion paper, by a Working Group of INTIMATE (Integration of ice-core, marine and terrestrial records) and the Subcommision on Quaternary Stratigraphy (SQS) of the International Commission on Stratigraphy (ICS), considers the prospects for a formal subdivision of the Holocene Series/Epoch. Although previous attempts to subdivide the Holocene have proved inconclusive, recent developments i

The origin of two large peaks in the atmospheric radiocarbon ((14)C) concentration at AD 774/5 and 993/4 is still debated. There is consensus, however, that these features can only be explained by an increase in the atmospheric (14)C production rate due to an extraterrestrial event. Here we provide evidence that these peaks were most likely produced by extreme solar events, based on several new an

The particle formation and growth events observed at a semirural background site in Denmark were analyzed based on particle number size distribution data collected during the period from February 2005 to December 2010. The new particle formation (NPF) events have been classified visually in detail according to 3D daily plots in combination with an automatic routine. A clear seasonal variation was

Very high levels of ambient particulate matter (PM) are frequently encountered in the north of Italy and air quality limits are regularly exceeded. To obtain quantitative information on the pollution sources and to gain understanding of the dynamics of pollution episodes in this populated area PM10 and/or PM2.5 samples were collected daily at nine urban to regional sites distributed over the centr

Mounting evidence from proxy records suggests that variations in solar activity have played a significant role in triggering past climate changes. However, the mechanisms for sun-climate links remain a topic of debate. Here we present a high-resolution summer sea-surface temperature (SST) record covering the past 9300 yr from a site located at the present-day boundary between polar and Atlantic su

Generalized frequency division multiplexing (GFDM) is a new concept that can be seen as a generalization of traditional OFDM. The scheme is based on the filtered multi-carrier approach and can offer an increased flexibility, which will play a significant role in future cellular applications. In this paper we present the benefits of the pulse shaped carriers in GFDM. We show that based on the FFT/I

Generalized frequency division multiplexing (GFDM) is a new digital multicarrier concept. The GFDM modulation technique is extremely attractive for applications in a fragmented spectrum, as it provides the flexibility to choose a pulse shape and thus allows reduction of the out-of-band leakage of opportunistic cognitive radio signals into incumbent frequency space. However, this degree of freedom

In this work we investigated the ability of a series of amino acids to act as cloud condensation nuclei using a static thermal gradient diffusion type cloud condensation nucleus counter. Particles of pure dry l-glycine, glycyl-glycine, l-serine, l-methionine, l-glutamic acid, l-aspartic acid, and l-tyrosine were studied as well as internally mixed dry particles containing ammonium sulfate and one
