In this thesis, we presented comparisons with respect to Energy Consumption, bandwidth, the Constraint application protocol (CoAP) transaction time and throughput for four different security protocols. We simulated and implemented the Datagram Transport Layer Protection (DTLS) version 1.2, Transport Layer Protocol (TLS) version 1.2 & 1.3, and Object Protection for Restricted RESTful Environmen

Utvecklingen kring tunga automatiserade fordon framskrider, med den digitala infrastrukturen forskas det mycket om hur man ska få de fordonen på vägarna med de konventionella fordonen. Flera tester sker på dedikerad infrastruktur utan att behandla de konventionella fordonen. Det har inte genomförts många projekt i Sverige eller internationellt för att utreda vilka krav som krävs för att få automatThe development of the heavy automated vechiles is progressing at a fast rate, with the digital infrastructure allot of reasearch has been made to understand how the automated vechiles will drive on the roads with the conventional vechiles. Tests are being made on the infrastruture without the usages of conventional vechiles. Not many projcts have been carried out in sweden or internationally to i

Finding vulnerabilities in open source code is getting more important with the increasing use of open source. The National Vulnerability Database (NVD) provides a database for public vulnerabilities, or CVEs (Common Vulnerabilities and Exposures), which is a standard for identifying vulnerabilities. NVD is the most common used source for vulnerabilities but there exists other vulnerability sources

The subject of the present thesis stems from my personal interest about the way Greek mythology has influenced the craft of composing for, and playing, the flute. Although I have always been connected to my heritage, this particular interest was piqued during my studies abroad and especially when I began to tackle Brian Ferneyhough’s Cassandra’s Dream Song (1970) for solo flute. Consequently, I ha

Det finns många vägar att gå i jakten efter en bättre förståelse för vår materiella världs minsta beståndsdelar, elementarpartiklarna. Vi kan bygga kraftigare och mer exakta partikelacceleratorer och därmed förbättra den experimentella delen av partikelfysiken. Vi kan också försöka hitta nya teorier om hur världen fungerar, något som i praktiken är väldigt komplicerat. Vi kan istället fokusera på In this thesis I extend the chirality-flow method to the full standard model at tree-level by including massive particles and electroweak interactions. The chirality-flow method is a new diagrammatic method for calculating Feynman diagrams that is based on the spinor-helicity formalism, that before this thesis was written had been worked out for massless QED and QCD at tree-level. I summarize what

This paper addresses the following hypothetical situation: suppose that we want to train an object detection algorithm but that only low resolution data is available. As a tentative solution to this problem, this paper suggest to first super-resolve the low resolution data to obtain higher resolution data that is then fed to the object detection algorithm. Super-resolution is a technique that take

Low-light image enhancement is a hard task mainly due to the amount of noise and little information stored in the dark image. In this thesis project we develop a method for low-light image enhancement based on a Conditional Variational Autoencoder (CVAE). The CVAE is a deep learning model trained with a specific objective function (ELBO). A CVAE can be implemented as a variant of a U-Net utilizing

Kraftvärmeproduktion är en produktionsteknik där både värme och el produceras i samma process. Eftersom produktionen innefattar små marginaler för att hålla sig konkurrenskraftig, är det viktigt att planera och optimera produktionen. En av de största kommersiella programvarorna för produktionsoptimering är Energy Optima 3 (EO3). I detta arbete analyserades denna programvara, som levereras av företCogeneration is a production technology where both heat and electricity are produced in the same process. Since the production includes small margins to stay competitive, is it important to plan and optimize the production. One of the largest commercial optimization softwares is Energy Optima 3 (EO3). In this study this software, which is supplied by the company Energy Opticon AB, was analysed wit

In this thesis, I investigate the use of the concept of the poor within Latin American liberation theology, with the aim to construct a common point of orientation for the different contexts of academic liberation theology. Drawing on Clodovis Boff's observation that there is a fundamental dissonance between liberation theologians’ discourse on the poor and the theologians’ conversation with t

Sweden consistently ranks among the most innovative economies in the world. Further, Sweden displays the highest venture capital per capita investments in Europe. From the literature, it can be derived that venture capital is regionally clustered, and that innovation in Sweden occurs in regional innovation systems. However, previous research provides no evidence concerning the relation between reg

Artificial Intelligence has become a hot topic as improvements in available technologies previously considered science fiction, like image recognition, language processing, and self-driving vehicles, are becoming financially viable. Further, several studies point to how automation of processes will increase efficiency in a variety of white-collar sectors. The public sector is no exception, and the

Åsikterna går isär kring om religion ska anses ha en betydelsefull roll som förklaring till demokrati och demokratisering. Med avstamp i frågeställningen om religion är en förklaringsfaktor till demokrati och om religion påverkar förutsättningarna för demokratisering undersöker vi sambandet mellan olika religioner och demokrati i två olika statistiska studier där vi också kontrollerar för indikato
