One of the basic requirements of today's sophisticated world is the availability of electrical energy, and neglect of this matter may have irreparable damages such as an extensive blackout. The problems which were introduced about the traditional power grid, and also, the growing advances in smart technologies make the traditional power grid go towards smart power grid. Although widespread utilisa
HQC is an IND-CCA2 KEM running for standardization in NIST’s post-quantum cryptography project and has advanced to the second round. It is a code-based scheme in the class of public key encryptions, with given sets of parameters spanning NIST security strength 1, 3 and 5, corresponding to 128, 192 and 256 bits of classic security.In this paper we present an attack recovering the secret key of an H
Cloud computing, owing to its ubiquitousness, scalability and on-demand ac- cess, has transformed into many traditional sectors, such as telecommunication and manufacturing production. As the Fifth Generation Wireless Specifica- tions (5G) emerges, the demand on ubiquitous and re-configurable computing resources for handling tremendous traffic from omnipresent mobile devices has been put forward.
Epilepsy is a chronic neurological disorder affecting more than 65 million people worldwide and manifested by recurrent unprovoked seizures. The unpredictability of seizures not only degrades the quality of life of the patients, but it can also be life-threatening. Modern systems monitoring elec-troencephalography (EEG) signals are being currently developed with the view to detect epileptic seizur
We present a reflector antenna system using a circular polarization selective surface (CPSS) to realize a circular polarization (CP) equivalent to the widely used linear polarization (LP) gridded or dual-gridded reflector (DGR). The CPSS is realized by a multilayer stack of non-resonant anisotropic meander line surfaces, achieving a very wide bandwidth. The CPSS reflection and transmission dyadics
The optimal spectral efficiency and number of independent channels for MIMO antennas in isotropic multipath channels are investigated when bandwidth requirements are placed on the antenna. By posing the problem as a convex optimization problem restricted by the port Q-factor a semi-analytical expression is formed for its solution. The antennas are simulated by method of moments and the solution is
This thesis proposes approaches and models to increase the energy saving of the User Equipment (UE) in Long-Term Evolution (LTE) and 5G. The focus is mainly on Discontinuous Reception (DRX), the UE energy saving mechanism that was first introduced in LTE and will play an important role in 5G too.In this thesis, we take two main approaches. The first approach is based on joint optimization of DRX a
Electromagnetic fields exist all around us. Through evolution, nature has developed tools to interact and use these fields, where our eyes are a spectacular example. Humans have a long history of developing structures and objects of their own to alter and interact with these fields. Today they are important cornerstones in society, with radiating devices such as cell phones, Wi-Fi routers, or car
Increasingly fine-grained cloud billing creates incentives to review the software execution footprint in virtual environments. For example, virtual execution environments move towards lower overhead: from virtual machines to containers, unikernels, and serverless cloud computing. However, the execution footprint of security components in virtualized environments has either remained the same or eve
Syftet med denna studie är att undersöka vilka metoder och strategier som gehörslärare lär ut till sina elever vid träning av det relativa gehöret. Undersökningen har sin utgångspunkt i svenska gymnasieskolans estetiska program med musikinriktning och i Musikhögskolan samt skolornas och pedagogernas egna undervisningsmål. Litteraturkapitlet handlar om tidigare skandinavisk forskning, relaterad tilThe purpose of this study is to investigate methods and strategies for relative pitch training that ear-training teachers teach their students. The investigation is based on the educational goals for Swedish upper secondary schools’ musical aesthetic program, and on academic bachelor level. The educators' own teaching goals are also considered. The literature chapter presents previous Scandina
För att kunna handskas med de stigande stressnivåerna hos skolelever är det viktigt att skapa en välfungerande lärandemiljö. Detta kan till exempel göras med olika verktyg och ett av dem är Woof Technologies ApS platform WOOF som kan användas som ett hjälpmedel för lärare i grundskolan för att mäta och arbeta med elevers trivsel och välmående i en klass. Syftet med detta arbete är att analysera ocIn order to deal with the rising stress levels of pupils, it is important to create a well-functioning learning environment. This can for example be done with various tools, one of them being Woof Technologies ApS platform WOOF which can be used as an aid for teachers in elementary school to measure and work with students' well-being in class. The purpose of this thesis is to analyze and eval
Talade utrymningslarm installeras som en riskreducerande åtgärd i byggnader där det vistas personer som inte kan väntas ha god lokalkännedom. En grundförutsättning för att utrymningslarmet ska uppfylla sin riskreducerande effekt är att det är hörbart, därav är ett talöverföringsindex, STI, på 0,55 rekommenderat. STI är ett mått på taluppfattbarhet som inte tar hänsyn till den subjektiva upplevelse
We live in what some call the “post-truth era”. Post-truth was appointed word of the year by Oxford Dictionaries in 2016. This thesis is a study on what significance different types of engagement on social media has on teenagers' knowledge about Swedish politics. This is important to understand because a great deal of the public debate concerning national politics nowadays takes place online.
The goal of this paper is to investigate the changing nature of India’s and Bangalore’s economy. This study will assess India’s change in the allotment of resources between different sectors within the state and country. To investigate the shifts, this paper will disaggregate the economy into three broad sectors, primary secondary and tertiary. It is expected that the much of the success of India
Det har aldrig gjorts något samlat försök att systematisera sakrätten från lagstiftarens sida. Särskilt separationsrättsliga problem är beständiga över tiden. Uppfattningarna om rättsläget beträffande separationsrätt vid sammanblandad egendom går isär. Det är svårt att se tydliga mönster i rättstillämpningen och förutsägbarheten är begränsad. Generellt sätt är rättsläget oklart. Vi vet inte vilka Rights in rem have never been systematized by the Swedish legislator. Especially problems regarding separation rights are recurring. Views differ on the owner’s right to separate intermixed property in a debtor’s bankruptcy or execution. The legal position is uncertain and predictability is limited. Since there is no general principle of separation right in the event of intermixed property and cas
We present a synchronized multisensory dataset for accurate and robust indoor localization: the Lund University Vision, Radio, and Audio (LuViRA) Dataset. The dataset includes color images, corresponding depth maps, inertial measurement unit (IMU) readings, channel response between a 5G massive multiple-input and multiple-output (MIMO) testbed and user equipment, audio recorded by 12 microphones,
