This report describes the development of an encrypted tunnel for the Crazyflie drone made by Bitcraze. This project began with the need for protection while using a Crazyflie drone in a public space. The Crazyflie drone is using open source software and has no protection against hijacking. Any phone able to download the app to control the drone is able to hijack and control the drone. To remedy th
I september 2017 fick nazistiska Nordiska Motståndsrörelsen demonstrationstillstånd i Göteborg, vilket orsakade en stor debatt i Sverige. En liknande debatt väcktes i USA 1977 när en nazistisk grupp ansökte om att demonstrera. Händelserna väcker frågor; bör demonstrationsfriheten innefatta nazistiska demonstrationer? Vad är statens förhållningssätt till våldsamma motdemonstranter? Syftet med uppsaIn September 2017, the Nordic Resistance Movement received a permit to march through Gothenburg, which ignited a big debate in Sweden. A similar debate was had in 1977 in the United States (U.S.), when a neo-Nazi group applied for a permit to demonstrate. These events provoke questions; should the right to demonstrate include neo-Nazi groups? What should the state’s approach be to violent counter-
Denna uppsats syftar till att utreda vilken betydelse erkännandet har i brottmålsprocessen i Sverige. Uppsatsens fyra frågeställningar utgör ramen, och innefattar såväl en allmän del om bevisprövning som en djupdykning i erkännandets prövning och styrka som bevis. I uppsatsen används huvudsakligen rättsdogmatisk metod. Dock görs även en undersökning av sex omtalade tingsrättsdomar för att se hur pThis essay aims to study the importance of confessions in Swedish criminal law procedure. The essay consists of a general overview of the court’s evaluation of evidence as well as an examination of how the courts perceive confessions and the strength of a confession as evidence. Six renowned district court rulings have been analyzed to see how the law is applied. Since this area is largely unregul
Regeringsformen (RF) 2 kap. 1 § ger inte tydlig ledning i fråga om vad som utgör legitima inskränkningar av yttrandefriheten. Lagtextens vaga utform-ning, samt skiftande praxis i förhållande till bestämmelsen gör det komplicerat att bestämma yttrandefrihetens omfattning i svensk rätt. Problematiken gör sig gällande i fråga om förhållandet till legitima inskränkningar, såsom bestäm-melsen om hets mThe second chapter, section 1 of the instrument of Government does not pro-vide a clear interpretation of what constitutes legitimate restrictions on free-dom of expression. This causes issues concerning the interpretation of free-dom of expression in Swedish law. The vague legal text, along with varying practices in relation to the provision, result in uncertainty regarding the extent of the free
Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolutio
Lubrication has been proven to be an effective approach to drastically improve the efficiency of ultrasonic motors without losing the output torque. This phenomenon is attributed to the effective modulation of the friction force by lubricant, according to the theory described in the Stribeck curve. Previous findings even show a potential to increase the motor output torque with lubrication. Here,
In this study we combine for the first time silicon (Si) isotope compositions of small mixed diatom species (δ30SibSiO2) and of large handpicked mono-generic (i.e. genus=Coscinodiscus) diatom samples (δ30SiCoscino) with diatom assemblages extracted from marine sediments in the Peruvian upwelling region in order to constrain present and past silicate utilisation. The extension of a previous core-to
The cross-section average (CA) augmentation approach of Pesaran (A simple panel unit root test in presence of cross-section dependence. Journal of Applied Econometrics 2007; 22: 265–312) and Pesaran et al. (Panel unit root test in the presence of a multifactor error structure. Journal of Econometrics 2013; 175: 94–115), and the principal components-based panel analysis of non-stationarity in idios
An interleaved pseudocinematographic FLASH (fast low-angle shot) sequence with additional pulsed gradients for flow encoding was used to quantify cerebrospinal fluid (CSF) flow velocities and CSF production. Flow-dependent phase information was obtained by subtracting two differently encoded phase images. The phase information in the resultant image was converted to flow velocity with a calibratio
BackgroundMost pharyngotonsillitis guidelines focus on the identification of group A streptococci (GAS), guided by clinical scores determining whom to test with a rapid antigen detection test. Nevertheless, many patients testing negative with this test are evaluated for group C/G streptococci (GCS/GGS) and Fusobacterium necrophorum, yet their importance remains debated. Our primary aim was to eval
Deciphering the genetic basis of prostate-specific antigen (PSA) levels may improve their utility for prostate cancer (PCa) screening. Using genome-wide summary statistics from 95,768 PCa-free men, we conducted a transcriptome-wide association study (TWAS) to examine impacts of genetically predicted gene expression on PSA. Analyses identified 41 statistically significant (p < 0.05/12,192 = 4.10×10
Transdisciplinary research (TDR) seeks to involve non-academic perspectives from the start, ensuring that research draws on diverse knowledge to better address “wicked” problems. Since TDR researchers have to engage with non-academic perspectives throughout the research process, this chapter focuses on the kind of communication practices that are appropriate and effective for engaging with people
Detta arbete undersöker hur den snabba utvecklingen av artificiell intelligens, med särskilt fokus på genererade bilder, påverkar bevisvärderingen och utred-ningsansvaret i svenska brottmål. Med utgångspunkt i principerna om fri be-visföring och fri bevisvärdering i 35 kap. 1 § rättegångsbalken analyseras hur domstolarna hanterar, eller bör hantera, invändningar från den tilltalade om att digital
Additive manufacturing enables multi-material functionally graded materials (FGMs) with expanded functionality, yet post-machining remains challenging because flow stress varies with composition. This paper presents a data-efficient, physics-guided Gaussian process (GP) model for predicting milling forces in SS316/IN718 FGMs without repeated force-coefficient identification. A physics-based millin

In iterative receiver structures, soft information becomes available after the decoding stage in the first iteration. This information is used to enhance the quality of the channel estimates for the next iteration. Channel estimation plays a crucial role in multi-user detection because the effective identification sequence for each user strongly depends on the channel characteristics. To combine d
