In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. The processing scheme was enabled by machine learning, implemented to compensate nonlinear noise in a comm
We propose a variable selection method for estimating decision rules of optimal sequential treatment assignments when the decision-relevant variables are unknown. Standard variable selection methods are insufficient in this setting since they choose covariates that are predictive of the outcome, not those that interact with the treatment on the outcome and are therefore relevant for decision-makin
Humanitarian aid faces increasing challenges in states who denies access to its citizens. The denial of access to humanitarian aid stems mostly from the view that aid organizations constitutes a threat to state sovereignty. However, recent studies suggest that in the case of Syria, the regime utilized humanitarian aid to instead bolster its sovereignty. To reach a better understanding of this rela
Augmented Reality (AR) är på uppgång och många företag lägger miljontals dollar i branschen. Både Google och Apple har nyligen släppt sina egna AR SDK’er som kommer att köras på miljontals enheter inom en snar framtid. AR är verkligen fascinerande och har sagts vara nästa miljard-industri. Målet med denna avhandling är att undersöka vad som är möjligt med dagens AR för mobila enheter och undersökaAugmented Reality (AR) is on the rise and a lot of companies put millions of dollars into the industry. Both Google and Apple have recently released their own AR SDKs that will run on millions of devices in the near future. AR is really fascinating and have been said to be the next multi-billion-dollar industry. The goal of this thesis is to explore what is possible with today’s AR and what are th
Purpose - The primary purpose of this thesis is to generate insights into the practical relevance and existing attempts of an aligned employer and corporate brand. The literature suggests that both employer branding and corporate branding are not aligned for a consistent brand, and each of the department responsible for the respective branding concept works in separate silos without cross-function
Innovation är ett vidkänt koncept som har fått ökad betydelse i dagens organisationer. Uppmärksamhet har framförallt riktats till de initiala faserna av innovationsprocessen, kallade Fuzzy Front End (FFE). Att hantera FFE effektivt har blivit nödvändigt i utvecklingen av nya innovativa produkter, eftersom det kan minska cykeltider och kostnader relaterat till produktutvecklingen. Det är dock svårtInnovation is a widely known concept which has received increased importance in today's organizations. Attention has especially been directed to the initial phases of the innovation process, commonly referred to as the Fuzzy Front End (FFE). Managing the FFE effectively, has become essential in the development of innovative products, since it can reduce cycle times and costs related to product
Tack vare nytänkande teknik och den tekniska utvecklingen, har en kombination av Cloud Computing, Internet of Things och Data Analytics kunnat realisera fenomenet smarta hem. Med syfte om att underlätta hushållens vardag genom diverse smarta enheter har tekniken med ständigt internetanslutna enheter i hushållen som hanterar känslig och personligt identifierbar data, har dock orosmoln kring den per
Bakgrund: Delegering av administrering och överlämnande av läkemedel till icke legitimerad personal är en allt vanligare lösning vid brist på sjuksköterskor med hot mot patientsäkerheten som följd. Syfte: Belysa huruvida patientsäkerheten påverkas då administrering samt överlämnande av läkemedel delegeras till icke legitimerad personal. Metod: En induktiv litteraturstudie utifrån tolv studier. Res
Listeria monocytogenes is a pathogen, sometimes occurring in fresh cheese, such as Queso Fresco. Antimicrobials could be utilized to prevent the presence of L. monocytogenes in this type of cheese. In order to be able to screen and assess several novel antimicrobials simultaneously in the future, the validated miniaturized laboratory-scale model for Queso Fresco (MLQF) was further developed into a
Advancement of technology with the aid of new application, wireless communication has grown rapidly in the past two decades. Recently, in the wireless communication industry, Narrowband- Internet of Things (NB-IoT) is being discussed by everyone, as the most important emerging technology of the day. Being a wireless technology, owing to the exodus of devices to be connected, with due consideration
I denna studie har vi observerat det kollegiala lärandet i två lärarlag som deltagit i fortbildningsinsatsen Läslyftet. Vid tillfället för våra observationer arbetade de båda lärarlagen med delen Ta ställning - elevaktivt, textnära och utforskande arbetssätt i modulen Analysera och kritiskt granska. Observationerna analyserades utifrån ett diskursanalytiskt angreppssätt som kompletterades med soci
Industrial Internet of Things (IIoT) is part of the well-known IoT concept where a large number of devices need to be interconnected in order to collect and exchange data. Companies’ aim is not only to minimize cost during product design, operation and maintenance but also to enable remote monitoring on the efficiency of the devices-assets through the utilization of cloud services. Low Power Wide
To optimize precision and accuracy of small dispensed volumes, a dispenser was built. A 96-well plate was loaded with four replicates of a linear pyranine dilution series to test the accuracy and precision of the dispenser machine. Three dilution series of pyranine (100-0 percent, 10-0 percent and 1-0 percent) were made. The results showed that the dispenser has very good accuracy and precision. T
In view of its complex demographic composition and the lingering controversies on recent civil war historiography, Lebanon provides a unique case of education in a post-conflict context. The absence of a common Lebanese national history curriculum puts individual history teachers under significant pressure. In lieu of an engagement with recent national history, avoided because of its controversy,
In this thesis a new method for the numerical solution of coupled systems of ordinary differential equations is investigated. To understand this new method, the workings of existing Waveform iteration methods, in particular the Jacobi and Gauß-Seidel methods were explored first. These methods were introduced to be able to exploit multirate behaviour in systems and use an iterative procedure to suc
The use of InP nanowires solar cells as a platform for the third generation concept of spectral conversion has been explored by embedding the Coumarin 120 dye between the nanowires of the solar cells. The InP solar cells have been characterised by measuring the external quantum efficiency, EQE, and the current voltage, JV, curve. For the EQE measurement an imaging system was constructed to constra
Engine lubrication is very important for engine sustainability and efficiency. It becomes even more important when heavier fuel types who contributes to lubrication are changed to alternative fuel without the same lubrication abilities. Because the performance of lubrication systems sometimes can be very hard to study in real time due to hostile environments inside engines, specialized techniques
Public participation is vital to ensure sustainable water management, and providing education is one of the way to trigger participation. For decades, developed countries try to educate their citizen to be environmentally literate, and for the water sector, water-related knowledge has been introduced to the public by schools, municipalities and water utilities. The condition is harder for developi
Manufacturing systems are becoming increasingly more complex at the same time as competition requires manufacturers to continuously improve their effectiveness and efficiency. The use of discrete event simulation to model manufacturing systems is well-established and generally considered to be the method of choice when analysing what-if scenarios. Simulation is currently predominantly applied when
