A packaging company is currently evaluating their production and searching for development opportunities to make the production more effective. At the facility for packaging materials there is a production line with two machine-groups consisting of two printers and one laminator. In the present situation the two machine-groups are disconnected from each other by the use of an inventory. The purp
Kiselalger, vattenlevande, mikroskopiska organismer med kiselskal, används som bioindikatorer för vattenkvalitet eftersom de är artrika och påverkas av sin omgivning. Processen kallas Kiselalgsmetoden och utförs genom en standard, en standard jag valde att analysera. Proven tas från stenar i vattendrag och sedan görs ett preparat som är fixerat på objektglas som kan undersökas i mikroskop genom aDiatoms, water living, microscopic organisms with silicon shells, are used as bioindicators of water quality because they are diverse and influenced by their surroundings. The process is called The Diatom Method and is accomplished through a standard, a standard I have chosen to analyze. The samples are taken from stones in water streams and then a preparation is made to fix the algae on slides t
Carbon-based materials are highly sought after due to their superior properties, making them valuable for high-performance applications. However, most carbon-based materials are derived from fossil sources, and their synthesis often involves hazardous chemicals. Therefore, it is essential to develop sustainable methods for synthesising these materials from renewable resources, using fewer solvents
This thesis presents methods for improving machining with industrial robots using control, with focus on increasing positioning accuracy and controlling feed rate. The strong process forces arising during high-speed machining operations, combined with the limited stiffness of industrial robots, have hampered the usage of industrial robots in high-end machining tasks. However, since such manipulato
The transition of industrial production from petrochemistry to a more sustainable economy requires the use of carbon neutral, renewable feedstock, which does not compete with food and feed supplies – by-products of farming and agro-food industry offer this possibility. With a limited range of low-value applications today coupled with the need for maximal utilisation of resources, the by-products o
Under covid-19-pandemin blev många anställda rekommenderade eller tvingade att arbeta på distans (Fackförbundet ST, 2020; Wang m.fl., 2021). Sammantaget arbetade 30–40 procent av arbetstagarna hela eller delar av sin arbetstid på distans under pandemin (Myndigheten för arbetsmiljökunskap, 2021). Den fysiska arbetsplatsen var inte längre en självklarhet; från en dag till en annan blev i stället dis
Nanosecond pulsed discharges (NPD) have been extensively used in plasma-assisted combustion to stimulate combustion kinetics. Experimental measurement of the energy transfer processes in non-equilibrium plasma-assisted processes is extremely difficult, as the non-equilibrium plasma discharge involves numerous different species with transient and complex three-dimensional structures across various
Context. Gaia Data Release 3 (Gaia DR3) contains the second release of the combined radial velocities. It is based on the spectra collected during the first 34 months of the nominal mission. The longer time baseline and the improvements of the pipeline made it possible to push the processing limit from GRVS= 12 in Gaia DR2 to GRVS= 14 mag. Aims. We describe the new functionalities implemented for
The global aviation industry is experiencing growing pressure to decarbonize, driving significant demand for Sustainable Aviation Fuel (SAF). Second-generation feedstocks that do not directly compete with food crops, such as lipid oils from insects and lignin-derived oils, are promising sources, but their high concentrations of inorganic contaminants and oxygen make them incompatible with existing
This study examines how public transport passengers experience and use travel time and under what conditions they are particularly concerned about shorter travel time. Using a survey of Swedish public transport users and a follow-up focus group, we compare current patterns with a similar 2009 study. Findings indicate a slight decline in perceived value of travel time, coinciding with a marked redu
Det har hävdats att den teoribildning rörande beslutsfattande under osäkerhet som utvecklats främst inom matematiken, men även inom den ekonomiska vetenskapen bland andra, med fördel skulle kunna inkorporeras även i den juridiska disciplinen. I första hand är det i detta sammanhang Bayes sats som avses, och denna sats tillämplighet på juridiska spörsmål. Detta började diskuteras på allvar mot slutThere have been claims put forth which aims at proving that the theories developed within mathematics, but also within economics to name one, regarding decision making and fact finding would suit very well to be adopted into the legal decision making as well. It is in this context primarily Bayes’ theorem which is referred and mentioned theorems compatibility with law. One of the first articles re
This master’s thesis presents a review of high school girls’ experiences of how information seeking concerning sexuality is handled and given space in the school library. In Swedish high schools, sex education is integrated into a number of subject areas rather than taught as an independent subject. This is reflected in school libraries’ collections, which often prioritize subjects that are stated
Background For companies’ long term survival it is essential to manage product rollovers successfully. It can even be more important than the product development in some cases. Unfortunately, most companies experience less than successful product rollovers. Several difficulties can jeopardise a successful rollover, such as: technical problems that can delay a new product introduction, excess prod
Departing from the increased interest in and beneficial characteristics of investments in commodity futures evident in the literature. This paper evaluates the existence of factors that may explain the cross-section of commodity futures through macro, equity and commodity specific factors. The models employed are estimated through the Fama-Macbeth two step approach on individual contracts as test
The purpose of this study was to investigate the relationship between the level of trait anxiety and to which extent the equestrians reinvest to consciously control their movements, and if the result had an influence on performance. The selected participants were 30 elite equestrians, actively competing in dressage. All participants were competing on a both national and international level in this
Traditionell biologisk näringsavskiljning inom avloppsvattenrening, såsom denitrifikation och biologisk fosforavskiljning (EBPR), kräver tillgång på lättnedbrytbart kol för att bra reningsgrad ska uppnås. Dock är en stor andel av kolet i det inkommande avloppsvattnet partikulärt och måste hydrolyseras innan det blir tillgängligt för bakterierna i den biologiska reningen. Flera studier har studerat
