Vi bedriver avancerad forskning om klimatet – vad som påverkar det, hur det har sett ut historiskt, hur biosfären interagerar med atmosfären, och vad vi kan förvänta oss av ett framtida klimat. Effekterna av klimatförändringarna kan redan ses i form av bland annat en ökning av jordens medeltemperatur, smältande isar och stigande havsnivå. Alla aspekter av liv berörs. Människans och jordklotets vil

Syftet var att undersöka om det fanns skillnader hos de barn som utvecklade autoimmun (typ 1) diabetes innan 6 års ålder jämfört med de barn som fick autoimmun diabetes när de var 6 år eller äldre.Totalt var det prover från 8502 barn som analyserades. Av dessa barn hade 328 (4%) utvecklat diabetes, varav 168 barn före 6 års ålder och 160 barn mellan 6 och 12 års ålder.Resultaten visade att:I Finla

Syfte: Syftet med studien är att undersöka effekten av ett kartläggningsbesök med efterföljande telefonuppföljning på användande av kommunikationsstrategier och hörselrelaterad livskvalitet för individer med betydande hörselnedsättning (TMV4 60-69 dB HL på bättre örat). Metod: Ett kartläggningsbesök utformades där fokus låg på individen och dennes upplevda besvär kring den egna hörselnedsättningen

The development of models that provide accurate spatio-temporal predictions of ambient air pollution at small spatial scales is of great importance for the assessment of potential health effects of air pollution. Here we present a spatio-temporal framework that predicts ambient air pollution by combining data from several different monitoring networks and deterministic air pollution model(s) with

Background: Cohort studies of the relationship between air pollution exposure and chronic health effects require predictions of exposure over long periods of time. Objectives: We developed a unified modeling approach for predicting fine particulate matter, nitrogen dioxide, oxides of nitrogen, and black carbon (as measured by light absorption coefficient) in six U.S. metropolitan regions from 1999

Cloud drop condensation nuclei (CCN) and ice nuclei (IN) particles determine to a large extent cloud microstructure and, consequently, cloud albedo and the dynamic response of clouds to aerosol-induced changes to precipitation. This can modify the reflected solar radiation and the thermal radiation emitted to space. Measurements of tropospheric CCN and IN over large areas have not been possible an

A key component in successfully managing software products is to properly, and in a timely manner, identify and secure competitive advantage by innovation via feature differentiation. Although open source software (OSS) is not a new idea, several product development companies that operate in a market-driven context have started to use open source solutions as core software components in their prod

We report 17 new solar activity cycles with periodicities ranging from 1,700 to 18,000 years. Using Bayesian spectral analysis we determined for each cycle period, amplitude and phase for the past 145,000 years. These results were obtained by analyzing 10Be in the 2775 m long EDML ice core from Dronning Maud Land, Antarctica. In addition, we have augmented the 10Be data with synchronous ice accumu

OBJECTIVE: To qualitatively explore the perceptions of Para athletes, coaches and stakeholders of the implementation, use and effects of the health promotion intervention 'Safe and Healthy Para sport' (SHAPE). A secondary aim was to explore participants' perceptions of how safety and health in Para sport could be further developed.METHODS: As part of a process evaluation, this qualitative, descrip

We introduce successive cancellation (SC) decoding of product codes (PCs) with single parity-check (SPC) component codes. Recursive formulas are derived, which resemble the SC decoding algorithm of polar codes. We analyze the error probability of SPC-PCs over the binary erasure channel under SC decoding. A bridge with the analysis of PCs introduced by Elias in 1954 is also established. Furthermore

This thesis focuses on algorithms and proofs of concepts in the area of wireless systems operating with a large number of antennas, especially at the base station side.The first studied topic concerns the design and implementation of massive multiple-input multiple-output (MIMO) testbeds, primarily for communications. This is an entirely new engineering challenge on its own, due to the unprecedent

Various improvements were made to a state-of-the-art aerosol–cloud model and comparison of the model results with observations from field campaigns was performed. The strength of this aerosol–cloud model is in its ability to explicitly resolve all the known modes of heterogeneous cloud droplet activation and ice crystal nucleation. The model links cloud particle activation with the aerosol loading

The ignition of nitromethane/O2/N2 mixtures was investigated via shock tube experiments in the temperature range 947–1333 K at reflected shock pressures near 8, 16 and 32 atm. The ignition was recorded as the intensity maxima of unfiltered luminosity in the range 240–530 nm. Under the experimental conditions of the present study, ignition was found to proceed via a two stage process. Dependencies

We present and analyze a new approach to improve energy efficiency in cellular IoT devices. The new approach consists of employment of ultra low power wake-up receivers in combination with robust non-coherent modulation. The results show that we can achieve very competitive power consumption, reducing it by up to 50 times, compared to two conventional power saving solutions we use as references. T

We envision the use of large intelligent surface (LIS) technology, which is a promising concept that goes beyond massive multiple-input multiple-output (MIMO), for positioning applications due to its ability to focus energy in the 3D space. The Cramér-Rao lower bounds (CBLBs) for positioning using a LIS which can resolve amplitude and phase with full resolution have already been determined in the

We present a new type of wireless access infrastructure consisting of a fabric of dispersed electronic circuits and antennas that collectively function as a massive, distributed antenna array. We have chosen to name this new wireless infrastructure 'RadioWeaves' and anticipate they can be integrated into indoor and outdoor walls, furniture, and other objects, rendering them a natural part of the e

Fast and accurate homography estimation is essential to many computer vision applications, including scene degenerate cases and planarity detection. Such cases arise naturally in man-made environments, and failure to handle them will result in poor positioning estimates. Most modern day consumer cameras are affected by some level of radial distortion, which must be compensated for in order to get
