Axial cutting force in drilling operation

Metallisk bearbetning har varit en del av den industriella utvecklingen sedan järnåldern. Sedan dess har det ändrat form och kriterier men effektivitet i skärande bearbetning av metall har varit ett av de största målen i den industriella världen lika länge. För att ha maximal effektivitet krävs en viss nivå av processbeteende, vilket är det som inspirerade examensarbetet. Projektet genomfördes i sMetal cutting has been part of industrial development since the iron age. Since then, it has changed shapes and criteria, but efficiency in metal cutting has been one of the biggest goals in the industrial world for just as long. To have maximum efficiency requires some level of process behavior prediction, which inspired the degree project. The project was conducted in collaboration with Lund Uni

Vad är jazz? En undersökning i hur harmonik, melodik, rytmik, improvisation och instrumentation påverkar ett musikstyckes uppfattade ”jazzighet”

Vad, från ett klingande perspektiv, exakt är jazz och var går gränsen för när det slutar vara det? I syfte att närma mig svaren på dessa frågor formulerade jag en kvantitativ enkätundersökning som huvudsakligen jämför klingande exempel. Enkäten fokuserar på de musikaliska aspekterna harmonik, melodik, rytmik, improvisation och instrumentation. Exemplen har jag konstruerat på så sätt att de jämför What, from a sounding perspective, exactly is jazz, and where is the boarder to when it stops being that? With the purpose of answering these questions, I developed a quantitative survey that mainly compared sounding examples. The survey focuses on the music aspects harmony, melody, rhythm, improvisation and instrumentation. I constructed the examples as such that they compare one or a couple of t

Talkin' 'bout my Generation

The retail industry is currently undergoing major changes, driven primarily by technological development and changing consumer behaviour. It has been shown that the behaviour of young people increasingly influences the attitudes and actions of older generations. This suggests that the new generation of young adults, Generation Z, may greatly influence the development of the retail industry. Based

Noise Reduction of Scintillation Camera Images Using UNET: A Monte Carlo Simulation Approach

Inom nuklearmedicinsk bildtagning injiceras en patient med ett läkemedel bundet till en radionuklid. De fotoner som emitteras kan detekteras med en gammakamera, vilket ger en planar bild av hur läkemedlet tagits upp i kroppen. Brusnivån relaterar till antalet fotoner som detekteras. En längre bildtagningstid och högre injicerad aktivitet minskar brusnivån, men ökar sannolikheten för rörelseartefakBackground The project aims to reduce the noise in planar 111-In projections with a machine learning model. Method Sixteen base phantoms were used to create 696 phantoms in XCAT. An anterior planar projection was simulated with 111-In and ten uptake curves for each phantom in SIMIND. From the 6960 simulated planar projections 55600 sample and label pairs were created by adding Poisson distribut

3D Printing Composites from Raw Materials

Under de senaste decennierna har friformsframställning, även benämt som 3D-utskrift, utvecklats snabbt inom både industri- och hobbyområdet. När nya applikationer upptäcks måste både material och metoder undersökas och utvecklas i samma takt för att inte hämma den kreativitet som 3D-utskrift framkallar. Materialet som vanligast används i 3D-skrivare är i filamentform, vilket produceras i storskaliFor the last decades, the subject of Additive manufacturing, also known as 3D-printing, has been rapidly developing in both the industrial and recreational fields. As new applications are discovered, materials and methods have to be researched and developed at the same pace to not stunt the creativity that 3D-printing brings out. The material most commonly used in 3D-printers are in a filament for

Guidance towards the Goals

The private sector is expected to take ownership and contribute towards achieving the UN’s Sustainable Development Goals (SDGs), and considering the innovative nature of start-up companies, they can be seen as key players. Though, they lack the guidance needed to assess the performance within the SDGs. Moreover, the literature within the field of sustainability assessment tend to focus on larger f

New era of automation in Scania’s manufacturing systems

Dagens bil- och lastbilsindustri upplevs ha komplexa produktionssystem med relativt höga tillverkningskostnader, varav en stor del kan kopplas till arbetskostnader vars arbetsmoment utgörs av komplexa och icke ergonomiska monteringsuppgifter. Genom att automatisera sådana uppgifter kan produktiviteten öka samtidigt som arbetskostnader och sjukfrånvaro minskar. Många produkter och monteringsoperatiToday's car and truck industries are perceived as having complex production systems and relatively high manufacturing expenses, such as labour cost, which is usually combined with complex and unergonomic assembling tasks. A shift towards automation is one solution to eliminate such tasks while increasing productivity and lowering labour costs. Many products and assembly operations are designe
