The study was carried out to identify critical factors for processed fruit shelf life in Tetra Recart packages. To investigate the importance of package volume and headspace volume, vitamin C was chosen to be the indicator. Oxygen in headspace, headspace volume, dissolved oxygen in product, oxygen transmission rate (OTR) and the concentration of vitamin C along storage time were measured to unders
The transport sector is one of many markets facing new challenges in the pursuit of reduced greenhouse gas emissions. The people at Volvo Powertrain in Malmö are continuously working to develop new and improved techniques that are able to live up to the ever-increasing legislations. A well performing turbocharger is an essential part of the combustion engine in order to reduce the fuel consumption
Quantification of CO2 emissions for case 1 - ISLK and case 2 - Föraren arrived at 42 and 125 CO2 per A_temp and with suggested changes it was possible to reduce to 38 and 109 CO2 per A_temp. The review of the possibility of lowering emissions in the manufacturing of concrete showed that the addition of fly ash reduced CO2 emissions by 10% per 10% of cement exchanged for fly ash. As well as demonst
Loudspeakers are used in many different applications and play a vital role in various types of entertainment and communication. To optimize the listening experience, there is a need for an adjustment process to compensate for any effects the environment might have on the loudspeaker’s performance. This thesis presents an adaptive method that utilizes an arbitrary amount of loudspeakers and microph
This master thesis aims at improving vehicle positioning in high-speed movement scenarios where global navigation satellite system (GNSS) does not work well. The standard 802.11p, as one of the WiFi family members, it can support to share vehicle information between vehicle and vehicle or between vehicle and infrastructure in a high-speed movement environment. Without the help of GNSS, the vehicle
Ultrasound Optical Tomography (UOT) is a proposed technique, which combines ultrasound imaging and optical imaging in a new way to detect, e.g., blood oxygenation and tumors deep inside biological tissue, where the ultrasound provides an excellent spatial resolution, and the optical imaging gives a high contrast of different tissues according to optical properties. However, the challenges of this
Since the purchasing expenditure of many companies is such a large part of the total cost and 99,8 % of companies are classified as Small and Medium Sized Enterprises (SME), one might expect that theories on purchasing strategy would not only be conducted for large companies but also SMEs. In order to fill this gap in theory, this thesis aims to create a purchasing strategy framework for SMEs in t
Biochar is a recalcitrant carbon rich solid product widely praised for the ability to improve soil fertility and sequester carbon, thereby improving crop yields and mitigating climate change. In addition to this, gaseous by products from production can be combusted for energy. Despite the recent global peaks in biochar research, studies focused on temperate regions are relatively scarce and few Eu
Many people today possess a private digital photo collection. Such collections are often just chronologically sorted. One way to make photo browsing more interesting would be to suggest semantically related photos to a currently viewed photo, and if, in addition, such a relationship could be justified in words, that would create extra value for the user. To find a solution to this problem, the ap
The purpose of this study was to embark on a theory in examining the unintentional effects affiliated with the law, when legislation took place in establishing border controls within the internal boarder. The study is aiming to focus on the affects travelers along with transportation companies experience on a day to day basis. Following the analysis method which is based on a theory by Robert K. M
Under min utbildning i musik och pedagogik har jag komponerat musik och därigenom utvecklat kunskaper i gehör, musikteori och komposition. Under mina kompositionsprocesser har jag stött på hinder och problem som ibland gjort att jag slutat att komponera. Med denna studie har jag konstruerat och skapat ett brädspel, Kompo, som verktyg för att komponera musik. När man spelar spelet resulterar detta During my education in music and pedagogy I have composed music, and through that developed my knowledge in ear, music theory and composition. During my composing processes I have sometimes stopped composing due to different obstacles. With this study, I have designed and created the board game Kompo as a tool for students to learn to compose music. The aim of this boardgame is that the players cr
There is a lot of discussion going on how to adapt to the changing climatic conditions, especially in countries where financial resources are limited. The built environment has been identified as a key area of intervention. As disasters, such as typhoons, can devastate entire cities, it is essential that the most important buildings in these cities, the lifelines so to speak, are resilient and can
Long working hours and burnout as well as other stress-related symptoms are common concerns amongst knowledge workers. An obvious solution might be to reduce working hours, for example, to a 30-hour workweek. Hence, this explorative study is interested in exploring the effects of the 30-hour workweek on knowledge workers. Object of study is a digital marketing agency; eleven semi-structured interv
Chirality of organic molecules plays a big role in areas ranging from medicine to material science, yet the synthesis of such entities in one enantiomeric form remains a challenge. Asymmetric synthesis is a key process in modern chemistry and allows us to achieve the selective synthesis of one enantiomer over the other. The design and development of new chiral ligands for metals is an exciting are
Experiments at particle colliders provide experimental verifications of theories in particle physics, and allow to search for new particles. Computer programs are used to simulate particle collisions. Those so-called event generators can be used to prove theories and compare their results to actual collisions from the colliders. Even though those programs run on powerful computer systems, the even
