Utbildning för vuxna lyfts ofta fram som en lösning på en rad aktuella samhällsutmaningar. Allt från miljöfrågor till den mer övergripande målsättningen att skapa ekonomisk tillväxt. Men vuxenutbildningen har också ett tydligt demokratiskt och medborgerligt uppdrag och i denna bok utforskas detta medborgerliga uppdrag utifrån dess grundläggande antaganden, verkningssätt och konsekvenser. Det är en
A channel sounder is an advanced measurement system to estimate the behavior of wireless propagation channels. In this paper, we present the antenna array design for a 28GHz massive multiple-input multiple-output system, capable of measuring 256×128 dual-polarized channels, including dynamic properties of angular, delay, Doppler, and polarization parameters, respectively. Unique in comparison to o
Efficient protection of huge amount of IoT produced data is key for wide scale data analytic services. The most efficient way is to use pure symmetric encryption as that allows both fast decryption at the analytic engine side as well as energy efficient encryption at the IoT side. However, symmetric encryption can only be performed if there is a way to directly map an encrypted object to the corre
Aim: The aim of this study was to describe personal care assistants' (PCA) experiences of working with a ventilator-assisted person at home. Methods: Data were collected from fifteen audiotaped semistructured interviews with PCAs supporting a child or adult using home mechanical ventilation (HMV). Thirteen women and two men participated; their working experience with HMV users ranged from one to 1
Several morphometrical methods were evaluated with the purpose of distinguishing individual maple trees by their samaras and to reveal shape trends. Landmarks for geometric morphometrics gave 97–98% correctly classified trees in a jackknifed confusion matrix from discriminant analysis, fan-positioned landmarks and semilandmarks 92%, linear data 79% and elliptic Fourier analysis 65% correctly class
Vehicle-to-vehicle (V2V) wireless communications can improve traffic safety at road intersections and enable congestion avoidance. However, detailed knowledge about the wireless propagation channel is needed for the development and realistic assessment of V2V communication systems. We present a novel geometry-based stochastic MIMO channel model with support for frequencies in the band of 5.2-6.2 G
The use of temozolomide (TMZ) for the management of aggressive pituitary tumours (APT) has revolutionised clinical practice in this field with significantly improved clinical outcomes and long-term survival. Its use is now well established however a large number of patients do not respond to treatment and recurrence after cessation of TMZ is common. A number of challenges remain for clinicians suc
Oscillations are a naturally occurring phenomenon in highly interconnected dynamical systems. However, it is thought that excessive synchronized oscillations in brain circuits can be detrimental for many brain functions by disrupting neuronal information processing. Because synchronized basal ganglia oscillations are a hallmark of Parkinson's disease (PD), it has been suggested that aberrant rhyth
In 2017 a new railway tunnel containing two stations opened in Stockholm, Sweden. A series of field measurements were carried out on the platforms in this tunnel before and after it was opened for normal traffic. These measurements were used to investigate the contribution of airborne particle emissions from wear processes to total train emissions. This field data was used to develop a two-part tr
Running-in process of low metallic brake pads and cast iron discs are investigated using full scale inertia brake dynamometer designed for particle emission studies. The airborne particles are measured using ELPI+ and collected on filters. The pads and disc contact surfaces are studied using microscopy techniques. It is observed that the particle emissions from the new pads and discs are significa
Unga forskare som vill göra akademisk karriär står inför många utmaningar. Deras tillvaro präglas av osäkra anställningar, motstridiga krav och begränsade erfarenheter av att stå på egna ben. Många befinner sig dessutom i familjebildande ålder. Kunskap om hur man kan göra för att må bra och nå framgång på sina egna villkor är sällsynt – få forskare låter andra få en inblick i deras forskartillvaro
BACKGROUND: Cognitive fatigue after childhood cancer is frequently overlooked despite guidelines recommending follow-up, and might be mistaken for depression due to overlapping symptoms. Our objectives were: 1) to examine ratings of fatigue in survivors of paediatric brain tumours (BT) and acute lymphoblastic leukaemia (ALL) compared to healthy controls, 2) to examine the relationship between symp
Introduction: Radiotherapy is an established treatment option for prostate cancer (PCa), both as primary treatment and secondary treatment after radical prostatectomy (RP). Since 1998, detailed data on radiotherapy delivered to Swedish men with PCa (e.g. treatment modalities, absorbed doses, fractionation) have been collated within PCa data Base Sweden (PCBaSe). This study reports patterns of radi
A key challenge in pilot training and performance assessment is the lack of insight into pilot visual behavior. Without this, it is difficult for an instructor to assess, e.g., whether pilots fail because they did not monitor the instruments or because they did not act on them, and whether pilots comply with monitoring aspects of the Standard Operating Procedures. Eye tracking provides the opportu
Convolutional Neural Networks (CNNs) have been subject to extensive attention in the pattern recognition literature due to unprecedented performance in tasks of information extraction from unstructured data. Whereas available methods for supervised training of a CNN with a given network topology are well-defined with rigorous theoretical justification, procedures for the initial selection of topol
The study describes development of a glycan biosensor for detection of a tumor-associated antibody. The glycan biosensor is built on an electrochemically activated/oxidized graphene screen-printed electrode (GSPE). Oxygen functionalities were subsequently applied for covalent immobilization of human serum albumin (HSA) as a natural nanoscaffold for covalent immobilization of Thomsen-nouvelle (Tn)
The objectives of the thesis were to seek a better understanding of polymorphic RBC surface molecules in the Thai, and to investigate the role of certain blood groups in malarial invasion. MALDI-TOF MS was employed in Study I as an efficient method for genotyping to establish the common blood group and platelet antigen genotypes of 396 blood donors. Investigation of outliers identified variation a
The aim of this study was to compare the influence of flow in the velocity range 0 to 25 mm/s on modulus, phase, real and imaginary images obtained with a standard magnetic resonance scanner (Siemens Magnetom, 0.5 T), and to develop a simple method for determination of flow velocities in vivo from this information. Using a flow phantom, the flow dependent magnetic resonance imaging (MRI) signal ha
Clinical researchers use disease progression models to understand patient status and characterize progression patterns from longitudinal health records. One approach for disease progression modeling is to describe patient status using a small number of states that represent distinctive distributions over a set of observed measures. Hidden Markov models (HMMs) and its variants are a class of models
