A cascade matched filtering (CMF) approach is purposed for filtering rectangular pulse train tracking signals, with known signal characteristics, in an embedded signal detection unit. Two adaptive detection algorithms are suggested, adapting to alterations in noise signal characteristics, due to environmental changes. The end product was an embedded tracking detection system, enabled to identify d

In the 'on-the-go' society of today, the use of single unit beverage packages has increased. Consequently, the interaction between the consumer and the package have also attracted greater interest when trying to gain advantages in a competitive market. One way of gaining such an advantage is by decreasing the developing costs of products: either by reducing time spent, or money invested in
In digital integrated circuits, memories are often a limiter for main performance, power and area. Over the past decade, integrated memories have gained dominance in terms of area and power cost. In applications like machine learning or image processing the area share can be above 80% consuming more than 50% of the total power budget. On-chip memories in CMOS technologies can be categorized as sta
In recent years, Deep Learning has proven to be an outstanding tool in the field of computer vision showing promising results in different fields such as the analysis of medical images, obstacle detection for self-driving cars, automatic image caption generation, etc. In the case of Archaeology, the adoption of these methods in the detection of archaeological structures from aerial images has been
This thesis has investigated the potential benefits of using transfer learning when training convolu- tional neural networks for the task of autonomously driving a car. Three transfer learning networks were trained and compared with a conventionally trained convolutional neural network. The first conclusion is that training, as expected, is considerably quicker when using transfer learning. More s
As design students who are about to graduate, we asked ourselves what it means to enter the professional life as a designer. We wanted to investigate how a young designer is able to make a living within the design profession. Additionally, we explored how we can include Northern European industrial manufacturing into our research and design process to learn more about mass production and its poten
I den här studien karakteriseras fenomenet anaerob korrosion utifrån både litteraturstudier om korrosionsprocesser och korrosionsprodukter samt genom undersökning av fältprover från betongkonstruktioner i salthaltiga undervattensmiljöer i södra Sverige. Anaerob korrosion av armering i vattenmättad betong är ett omfattande men hittills relativt ouppmärksammat problem. Detta fenomen kan leda till alIn this study, the phenomenon of black corrosion is characterized by both literature studies on corrosion processes and corrosion products, and by analyzing field samples from saline subaqueous concrete structures in southern Sweden. Anaerobic corrosion of reinforcement in water-saturated concrete is an extensive but yet relatively unnoticed problem. This phenomenon can lead to serious damages tha
The evolution of World Wide Web (WWW) into semantic web is happening with the aid of standards like Resource Description Framework (RDF), SPARQL and a few others from World Wide Web Consortium (W3C). Over the years, semantic data management technologies have been introduced as software platforms commonly known as RDF stores. Lately these RDF stores have been tested for processing and maintenance o
A model of the Swedish power plant Mälardalen Energi, developed by Solvina AB was simulated in Dymola with different types of control strategies in order to evaluate if they could improve the operational flexibility of the plant and, thus, its ability to deliver frequency control to the Swedish power grid. Several different control strategies and process modifications were tested and compared to p
The National Risk and Capability Assessment (NRCA) is used by the Swedish Civil Contingencies Agency (MSB) to decide to develop annual strategic plans. NRCA is carried out by dedicated experts in workshops and interviews with other actors’ representatives, etc. An alternative to this, could have been that the NRCA is performed based on risk and vulnerability assessments (RVAs) conducted by the Swe
The municipality of Ängelholm requested information on how to improve their urban green areas for pollinators. To find out the current status of pollinators, bumblebees, other bees and hoverflies, and to identify the key determinants of their diversity, two types of inventories were made during 2018, field observations and collection with pan traps. 14 sites in central Ängelholm were chosen based
Elevation models are important in many applications in Geographical Information System (GIS), both when applying environmental analyses and in urban planning studies. The production of elevation models has been a difficult and expensive task using traditional surveying techniques. Remote sensing methods for producing digital elevation models have solved the difficult part of the task, which consis
When designing a building one must consider safety aspects. One such aspect is that in the case of an emergency people should be able to efficiently evacuate the building. In this paper we investigate how the width-profile of a corridor leading to an exit might affect the efficiency of evacuation. We model the dynamics of crowds using a continuum model, leading to a one-dimensional non-linear hype
The electricity sector is in the beginning of a large shift from centralized dispatchable production to distributed variable production. With this necessary change, new challenges arise. One crucial challenge is related to upholding the system balance in the power grid. In this master thesis, a Battery Energy Storage System (BESS) has been implemented in an HVDC-system with large amounts of Wind P
Moderaternas förslag om bidragstak syftar till att öka de ekonomiska incitamenten för hel- och deltidsarbete i gruppen av bidragstagare med arbetsmarknadsrelaterade försörjningshinder och högt ekonomiskt bistånd. Detta arbete är en typfallsstudie vilken behandlar förändringen i ekonomiska incitament vid införande av bidragstak. Förslagets potentiella påverkan studeras utifrån hur många hushåll som
One of the main challenges in evolutionary ecology is to identify the factors and agents that drive diversification. Two of the most diverse groups of organisms on earth are plants and insects, and evidence strongly suggests that the diversification of both groups is driven by the interactions between them. One fruitful way for understanding how these interactions evolve and diversify is to identi
Syftet med examensarbetet är att studera ledarskapet och ledarens roll i förändringsarbetet mot ett klimatneutralt byggande. I studien utreds vilka faktorer som driver förändringsarbetet mot ett klimatneutralt byggande och hur miljöarbetet kan bli mer attraktivt för anställda i svenska byggföretag. Studien har utförts på ett fallföretag och ett av deras projekt i produktionsfasen. En kvalitativ mThe purpose of this master thesis is to study the leadership and the roll of the leader during a change in the process towards a climate neutral construction process. The study is aiming to find factors which affects the change process towards a climate neutral construction process as well as how the environmental work can become more attractive in projects. The study has been carried out as a ca
In 2009 the Swedish parliament decides to discontinue the conscript service, and in 2010 it was replaced by a system based on employed personnel. The purpose of this study is to analyze the factors leading up to the decision to abandon conscript service. This question is interesting to study because the conscript service was reinstated only seven years later due to a worsen security situation and
