Antimicrobial resistance is according to the World Health Organization (WHO) one of the most rapidly growing threats to world health. According to a recently published WHOreport, drug resistant microbials could be responsible for up to 10 million annual deaths by the year 2050 unless drastic measures are taken such as decreasing misuse and developing new antibiotics. This work explores the possibi
Matrix functions and their applications play an important role in different fields of science and engineering. The matrix exponential is one of the most important and extensively used function of matrices. The computation of the exponential of a matrix is an interesting topic that has been extensively studied over the years. There are several ways computing the matrix exponential but there is a pu
Sociala medier är idag ett självklart inslag i många människors liv, och deras utrymme i samhället fortsätter att expandera. Vår självkänsla är viktig för vår psykiska hälsa då en bra självkänsla fungerar som ett slags “psykologiskt vaccin” mot psykisk ohälsa. Med detta som bakgrund är det tydligt att det är ett viktigt fokus att bygga på den forskning som redan har undersökt sambanden mellan sociA lot of people are using social media today, and the usage is continuously increasing. Our self-esteem is important for our psychological health since it works as a “psychological vaccine” against psychological ill-health. With this being said it is clear that it is important to add to the research that has already been done regarding the correlation between social media usage and self-esteem. Th
A bachelor project in the course studio: Contemporary Architecture, at Lund School of Architecture. The aim of this course was to develop spatial and structural typologies through experimentation with the digital design process. The main focus has been to manage computer modeling with Rhinoceros and Grasshopper.
Elektrifieringstrenden inom transportsektorn tycks under hösten ha lämnat marken; elflyg anses vara ett av svaren på hur luftfarten skall reducera sin omdebatterade klimatpåverkan i framtiden. En ökning av tunga elektrifierade fordon, inklusive flyg, resulterar i konsekvenser för elsystemet sett till ökat effektbehov och nya lastprofiler. Examensarbetet ämnar således undersöka vilken roll regional
The knowledge of desert locust plagues goes back to biblical times but it is just as relevant in 2020 with an ongoing outbreak in East Africa and the Middle East. The locusts pose a threat to agriculture, and by extent food availability, due to their high appetite, diverse diet and ability to migrate long distances in large swarms. More knowledge of the aftermath is required by the international d
Fordonsindustrin elektrifieras just nu i en snabbare takt än någonsin. Allt från elektriska cyklar till Segways och elektriska longboards. Alla dessa kräver nya sorters interaktioner för att styra motorn. Segway har till exempel utnyttjat användarens lutning som ett medel för att bestämma om personen vill åka fram eller bak. Elektriska longboards använder sig ofta av en handhållen kontroll med en The automotive industry is now electrifying at a faster rate than ever before. Everything from electric bikes to Segways and electric longboards requires new kinds of interactions to control the engine. For example, Segway has used the user's tilt to decide whether they want to go forward or backward. Electric longboards often use a handheld controller that has a gas button. Now, this electrif
The discovery of penicillin and the many antibiotics after that, has given our society a heightened sense of confidence when dealing with everything from the everyday bacterial infection to complicated surgical procedures. However, more and more bacterial species are becoming resistant to antibiotics. 33000 deaths attributed to antibiotic-resistant bacteria occurred in Europe in 2015, a number tha

Tröger’s base molecule has a unique V-shaped cavity and a chiral structure. These molecules can be fused together in a linear fashion to create either tubular structure or zigzag structure. Different fields can be benefited from the applications of these molecules. Previous studies carried out in the Wärnmark group led to 30-step synthesis route to get a linearly fused heptakis-Tröger’s Base anal
Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. Based on temperature- and wheel-speed measurements, a mathematical model of
Största delen av det svenska vägnätet består idag av belagd väg. Med det i åtanke så krävs det därför att vägarna vid sin anläggning respektive när underhållsåtgärd sker blivit väl dimensionerade samt blivit korrekt utförda. Under en tid i Sverige har Trafikverket med sitt dokument TRVK väg numera TRVINFRA styrt hur de statliga vägarna skall dimensioneras med sina tre dimensioneringsklasser. I dirThe largest part of the Swedish state roads are today paved. With this in mind it is therefore demanded when a road in question is constructed respectively when a maintenance measure is taken place that the dimensioning of the road from the start was done properly. Since a while back in Sweden it has been upon the Swedish Transport Administration to regulate with their document “TRVK Väg”, now TRV
This research paper investigates notions and values that composers have regard to artificial intelligence and composition. The research is based on a survey that was sent to students and teachers of composition at Malmö Academy of Music. A total of 32 emails were sent, of which 15 were answered. 12 of the informants were students and 3 were teachers. Of the 32 individuals surveyed, the number of t
Power system infrastructure has been facing many challenges when it comes to harmonics distortion, and power electronic devices are no exception considering their wide usage in the system. In this thesis the focus is on the impact of these system harmonics on the electrical motors which are vastly used in industry for different applications. Motors usually come with a softstarter, and are connecte
Syfte: Syftet med studien är att undersöka kulturell påverkan av kreativa inslag i standardiserad reklam. Med studien vill författarna bidra marknadsföringsbyråer med en utökad förståelse för hur den kultur som är associerad med landet inom vilken byrån agerar kan ha en omedveten påverkan på produktionen av reklamfilm. Metod: I studien utför författarna en semiotisk innehållsanalys av standardiPurpose: The purpose of the study is to investigate the impact that a country's culture has on the use of creative elements in standardized advertising. Thus contributing to the understanding of how the culture associated with a country in which a marketing agency operates can influence their production of commercials. Methodology: The study is a content analysis of standardized commercials p
Climate change is the greatest challenge of our time. Despite efforts to reduce greenhouse gas (GHG), the emissions contribution from global aviation is set to increase. Electric aviation has emerged as an alternative which could form part of the solution. Sweden, which is on the path to carbon neutrality and has a long history in aviation, could contribute to the global efforts in mitigating clim
Unfriending someone on Facebook is a phenomena which can be seen in many different contexts and unfriending someone for political reasons can create obstacles for political conversations as it can increase polarization in society. In recent years there has been a tendency of unfriending individuals that express sympathies for the political party Swedish Democrats (SD) which can be perceived as sti
