Den här avhandlingen handlar om luftburna designade nanopartiklar och hur mantar reda på vilka egenskaper de har. Luftburna partiklar eller aerosoler är något sommänniskan alltid har haft omkring sig. Oavsett om det varit i form av pollen, rök fråneldstaden, eller från astmainhalatorn så har de alltid varit där och påverkat oss. I varjeandetag drar vi in flera tusen partiklar, men vilken typ de ärThis thesis will explore parts of the life of engineered nanoparticles, from generation in research environments andprocess monitoring, to emissions in an industrial setting. The aim is to give insights into how the particles can becharacterized in different settings and how different characterization methods can be applied depending on need ordemand.Airborne nanoparticles have been around forever

Corporate wellness programs can help employees improve their health and well-being. There are many advantages to a healthy workforce including increased productivity and lower health insurance premiums. A growing trend in corporate wellness programs is to offer wearable fitness trackers to employees to help them monitor their activity so that they can make better choices about their health. It is

Lightweight buildings are sensitive to low-frequency vibrations, making it difficult to construct them in such a way that noise and disturbing vibrations are kept at an acceptable level. In the design of vibration reduction measures, it is desirable to have computational models for predicting the effects of structural modifications. Validations of the models to experimental data have to be perform

Children can and should be encouraged to take an active part in their own care. With the introduction of online health care centers, where the main interaction is provided through digital consultations, the process for including the child must be revised. In addition to the medical and legal challenges, the digital interface needs to be designed so that the parent is encouraged to involve the chil

Vibration of machinery and construction work are major sources of noise and vibration pollution in the urban environment. The frequencies dominating the vibration, and the distances over which it spreads via the ground, depend on the source. However, soil stratification and foundation type have a significant influence. Thus, in order to achieve fair accuracy in the prediction of ground vibration c

Construction of high-speed railway lines has been an increasing trend in recent years. Countries like Denmark and Sweden plan to expand and upgrade their railways to accommodate high-speed traffic. To benefit from the full potential of the reduced commuting times, these lines must pass through densely populated urban areas with the collateral effect of increased noise and vibrations levels. This p

This work treats the estimation of the chromagram for harmonic audio signals using a block sparse reconstruction framework. Chroma has been used for decades as a key tool in audio analysis, and is typically formed using a Fourier-based framework that maps the fundamental frequency of a musical tone to its corresponding chroma. Such an approach often leads to problems with tone ambiguity, which we

The computation of the Capon and the amplitude and phase estimation (APES) filters can be very time consuming. The burden lies not only in the inversion of the sample covariance matrix, but also in the matrix multiplications. In this paper, we propose an efficient algorithm for the computation of the above mentioned filters, using Cholesky factorization and fast Fourier transforms. Furthermore, we

Introduction During the embodiment design and detail design phase, the designer has at his disposal a set of tools and techniques that him or her through the synthesis activity: basic rules, guidelines and principles (see [1]), but in the literature there are general design processes that help the designer to organize their work (e.g. [1]), but not at a very operational level. From a previous stud

Electric vehicles have recently garnered significant attention in the research community due to their potential has a large, highly controllable load which can be used in demand response, load shaping, and renewable energy integration. However, research into practical charging algorithms has been hampered by the lack of a widely available, realistic simulation environment. To meet this need in the

Creativity is a wildly debated topic among scholars and practitioners, but one that lacks consensus. Many have tried to define, describe and explain creativity, its purpose, effect and use. Is creativity a personality trait you are born with, or can you learn to become creative? As a design teacher with a teaching practice focused on the skills of creativity, this is a relevant question, because i

In this paper, an aerosol-based process is proven for imparting antibacterial property to textiles. Nanoparticles of copper and silver are produced by means of glow discharge between two electrodes in nitrogen at atmospheric pressure and passed through fabrics of cotton and polyester which act as filter media. The bactericidal performance of the nanofinished fabrics is assessed against Gram-positi

With cyber-physical systems opening to the outside world, security can no longer be considered a secondary issue. One of the key aspects in security of cyber-phyiscal systems is to deal with intrusions. In this paper, we highlight the several unique properties of control applications in cyber-physical systems. Using these unique properties, we propose a systematic intrusion-damage assessment and m

The ESS linac will deliver an unprecedented 5 MW of average beam power when completed. Beyond the 90 MeV normal conducting front-end, the acceleration is performed using superconducting structures up to the design energy of 2 GeV. As the ESS will send the beam to a fixed tungsten target, the emittance is not as important a factor as in injectors. However, the losses have to be studied in detail, i

The ESS linac is currently under construction in Lund, Sweden, and once completed it will deliver an unprecedented 5 MW of average power. The ion source and LEBT commissioning starts in 2018 and will continue with the RFQ, MEBT and the frst DTL tank next year and up to the end of the fourth DTL tank in 2020. This paper will summarize the commissioning plans for the normal conducting linac with foc

The development of a high precision five rotation axes polarimeter using transmission multilayers as polarizers and reflection multilayers as analyzers is presented. In order to cover a wide energy range from EUV to soft X-ray, a set of Mo/Si, Cr/C, Sc/Cr, and W/B4C multilayers for transmission and reflection have been designed and fabricated. A hexapod support allows to align the polarimeter easi

The implementation of circular initiatives requires certain capabilities and knowledge that traditional business models often lack, requiring new perspectives and external collaborations. This paper explores the competency needs and partnership dynamics of established companies collaborating for business model innovation for circularity through a case study of a gap exploiter business model, a com

Popular Abstract in Swedish "Så det var, vad ska vi kalla det för, chefskräck. (...) Och jag kände det att 'jag har ingen kontroll just nu över läget'. Då kände jag en fruktansvärd dödsångest och den förlamade mig fullständigt. (...) Då tappar man allt logiskt tänkande. Man blir helt djurisk, flykt, man springer." Så beskriver en svensk officer hur han reagerade när hans förband blev beskjutet unThe overall purpose of the thesis was to increase knowledge concerning how people adapt psychologically when faced with a real danger incident, and what implications these reactions and adaptation mechanisms have upon immediate performance. The thesis is based on three empirical studies concerning people with personal experience of dangerous incidents. Swedish peacekeeping personnel who were invo
