Classification of airborne laser scanning data using information about intensity and width of the recorded signal Abstract One of the basic tasks in analysing airborne laser scanning (ALS) data is filtration of mass 3D point cloud with purpose to create digital terrain model and digital surface model. New scanner generation (so called Full-waveform LiDAR) allows analysing the whole recorded signal. The recorded value of amplitude and signal width accordant with reflectance of different objects differs according to geometry of the objects. Objective of this thesis is to create a methodology for classification of ALS data in settled areas. This methodology will be based on number of reflections, amplitude of reflected signal, recorded signal width and on spatial attributes. At the same time it will be analysed how the parameters of amplitude and signal width are affected by characteristics of estate surface. It means which radiometrical characteristics (e.g. different roof materials) and geometrical characteristics (e.g. different roof inclination) belong to which amplitude and signal width. Basic question of this thesis is if amplitude and signal width are good attributes to improve the quality of filtration of mass 3D point cloud in chosen area and if so, how. Key words: classification, segmentation, LiDAR,...

Links: Aerobic motion activity as it is offered in commercial aerobic classes is generally considered to be beneficial for the motion apparatus, and for one's overall health. Nevertheless, loud music accompanying the exercise can rather cause damage to one's health. Goals: The main scope of my thesis is to measure the noise intensity in commercial aerobic classes and to verify whether the noise does not exceed the limits permitted by hygienic standards. Methods: In my thesis I used a specific method for determination of the noise intensity in the aerobic class space. I opted for the noise level according to EPA standards ranging between 70 and 80 dB as the basic constant. The measurement itself took place after calibration in eleven measured spots in a fitness centre located in České Budějovice. The measured spots were established in the space according to the placement of the sound apparatus and the measurement itself took place in the height of the sound apparatus of a fitness centre client. The measured values were further processed into descriptive graphs and all outcomes were further processed using statistical methods in order to verify the measurement validity according to statistical significance. Results: On the basis of the performed measurement, data processing and the following...

In many financial agent based models, the concept of adaptive switching be- havior is employed as a substitute for the, elegant yet unrealistic, assumption of rational expectations. Studies estimating these models however frequently suggest that agents do not behave adaptively. To better understand the source of this discrepancy, we propose a test for the presence of switching which does not require us to specify beforehand the exact form of the switching mecha- nism nor the strategies among which agents can choose. We verify the ability of the test to detect switching by Monte Carlo simulations and then apply it to stock prices from the New York Stock Exchange. The null hypothesis of the absence of switching is strongly rejected. Furthermore, we assess robustness of this finding by applying the test individually to various sub-sets of the data-set. The switching is prevalent in all considered sub-periods and in all groups of stocks categorized by traded volume.

Approved for public release; distribution is unlimited / During the Gulf War, millions of people around the globe, courtesy of CNN, witnessed the seemingly massive use of precision-guided weapons against Iraqi targets in the largest air campaign since World War II. Most of the missions were flown against Iraqi targets with no friendly forces on the ground. This type of air campaign is known as Deep Air Support, or 'DAS'. Equally as important, but receiving less spectacular news coverage, is Close Air support, or 'CAS'. When conducting CAS missions, the chance for 'Friendly Fire' incidents, injuring or killing your own troops on the ground, increases dramatically as compared to DAS missions. This may seem to be an obvious deduction since there are no friendly troops on the ground during a DAS mission but when small, specialized units, such as SEALS, Special Operations Forces (SOF), or reconnaissance forces find themselves in the deep battlespace, operating in a low intensity conflict (LIC) environment, these simple doctrinal distinctions can sometimes lead to confusion, or worse, friendly fire fatalities on the battlefield. It could be argued that there is a disconnect between joint doctrine and joint training which creates an environment on the LIC battlefield, as well as in training, that can lead to faulty execution of CAS missions, and potentially disastrous results, jeopardizing the safety of the very same ground personnel we are trying to support. / Major, United States Marine Corps

Background: Pain is a common postoperative experience. Guidelines recommend performing regular pain assessments, which include self-rated pain and additional communication to capture patients' experiences. During hospitalisation, pain intensity is found to be a vital factor influencing other aspects of an early physical recovery, and is consequently an important item in questionnaires for recovery. These tools consist of extensive questionnaires which are difficult to use in everyday clinical work. A simplified method of monitoring postoperative recovery would benefit both patients and healthcare professionals. Aim: The overall aim of this thesis was twofold: (A) to determine the ability of extending the use of pain ratings to reflect and predict early physical postoperative recovery and (B) to describe patients’ perspectives on pain assessments. Methods: The studies were carried out at one (I), three (IV) and four hospitals (II, III) involving general surgical and orthopaedic inpatients. Two quantitative methods were used based on data from questionnaires and medical records. They consisted of one cross-sectional study (I) and one study with repeated measures (IV). An association was sought between pain intensity and postoperative recovery on days 1 and 2 (I, IV), and prehospital data (IV). Two qualitative methods were used involving a phenomenographic (III) approach and Critical Incident Technique (IV), where semi-structured interviews were performed postoperatively and analysed inductively in accordance with the approach. Results: An association was found between moderate/severe average pain intensity compiled from monitoring records and impact on early physical postoperative recovery on day 1 (I). Retrospective average pain intensity at rest and during activity reflected impact on recovery on postoperative day 1 (IV). Severe pain intensity at rest and during activity on postoperative day 1 predicted impact on physical recovery items on day 2 (IV). The use of the Numeric Rating Scale (NRS 0-10) was considered to facilitate communication about pain, but to involve difficulties of interpretation and place demand on healthcare professionals and care routines (II). Patients’ descriptions of their experiences when in need of describing pain indicated two main areas: patients’ resources when needing to describe pain and ward resources for performing pain assessments (III). Descriptions of their actions when they were in pain indicated two main areas: patients used active strategies when needing to describe pain or patients used passive strategies when needing to describe pain (III). Conclusions: This thesis contributes to knowledge about the possibility of using patients' self-rated average pain intensity to reflect early physical postoperative recovery on day 1 and to predict recovery on the following day. The pain scale gave patients and healthcare professionals a shared vocabulary, which facilitated communication. Furthermore, dialogue during pain assessments was described as critical in ascertaining whether pain intensity had an impact on different aspects of physical recovery. Environmental factors such as the attitude of healthcare professionals, workload and staffing influenced how pain assessments were performed.

The electrical energy consumption in thermomechanical pulping (TMP) is very high, in the range of 2 – 3 MWh/adt depending on process solution and on the product quality specifications for the paper product. Both pulpwood and energy prices have increased rapidly for some time. Due to this, the main focus of the research and development is on ways to reduce the electrical energy consumption in wood chip refining. As a step towards a more energy and cost ‐ effective refining process, Holmen Paper AB has invested in a new mechanical pulping process at its Braviken mill. In this case the primary refining stage consists of high consistency (HC) double disc refiners ‐ RGP68DD (machines with two counter rotating discs). Earlier studies on the refining conditions, such as intensity and temperature, have indicated that it should be possible to improve the energy efficiency in double disc refining while maintaining the functional pulp properties such as tensile index. The main goal of this project was to improve the energy efficiency in double disc chip refining with 150 kWh/adt to corresponding pulp properties as measured on pulp samples after refiner. In order to further improve the basic understanding of what happens to the wood fibre material when changing the process conditions, the morphological and ultrastructural changes of fibres were also studied. This part of the research work was performed in cooperation with the research program; Collaborative Research on the Ultrastructure of Wood Fibres (CRUW). This licentiate project is a part of a large development project where different techniques to improve the energy efficiency has been evaluated by means of mill scale trials at the Holmen Paper Braviken Mill. The high consistency double disc chip refining part of the project was financed by The Swedish Knowledge Foundation, Metso Paper and Holmen Paper, in cooperation with FSCN (Fiber Science & Communication Network) at Mid Sweden University. The trials were made on one of the TMP lines at the Holmen Paper Braviken mill with Norway spruce as raw material. The influence of increased specific      refining energy on pulp properties were studied at different refining temperatures, refining intensity, pulp consistency and production rate. Results from these trials were later validated by means of long term trials. Intensity models and simulations for intensity changes by new segment design were made by Juha‐ Pekka Huhtanen from Tampere University of Technology, Finland. The results show that the specific energy consumption to same tensile index can be improved by means of increasing the refining pressure/temperature. The energy efficiency was improved by 80     ‐150 kWh/adt depending on load and the inlet‐ and housing pressure. The largest relative specific energy efficiency improvement was reached at low specific energy consumption levels. Similar fibre surface ultrastructure characteristics are gained by pulps with high pressure/temperature and low specific energy consumption compared to low pressure/temperature and high specific energy consumption pulps. High pressure/temperature and high specific energy consumption resulted in significantly increase in the delamination/internal fibrillation of pulp fibres. The surface ultrastructure of these fibres exhibited exposed S2 layer with long ribbontype fibrillation compared to pulps produced with lower temperature and lower specific energy consumption. When the refiner was operated at high pressure, the tensile index was preserved over the whole plate life. The specific light scattering coefficient increased with increasing pressure/temperature. A reason for this could be increased intensity caused by decreased plate gap. Increased intensity by means of refiner segment design changes resulted in large specific light scattering coefficient increase at similar tensile index, lower shives content, lower average fibre length and lower CSF at same specific energy consumption. The fresh steam consumption was reduced by the increased refiner ressure/temperature. / Den höga elenergiförbrukningen vid produktion av mekanisk massa har ställtkrav på mer forskning för att elenergieffektivisera raffineringsprocessen. Som ettsteg mot en mer energi‐ och kostnadseffektiv raffineringsprocess, har HolmenPaper AB investerat i en ny tillverkning av termomekanisk (TMP) massa vidBravikens pappersbruk. Dubbeldiskraffinörerna i den nya massalinjens primäraraffineringssteget studerades i detta projekt. Det finns goda indikationer på att enminskning av energiförbrukningen är möjlig genom att studerar och optimeraraffineringparametrar såsom intensitet och temperatur. Projektets huvudmål varatt energieffektivisera det primära dubbeldiskraffineringssteget med 150 kWh/adttill motsvarande massaegenskaper, så som dragstyrka, mätt på massa efterraffinör. Tillfälle gavs också till att studera morfologiska förändringar på fibrer föratt ytterligare förstå hur massa och fibrerna påverkas av dubbeldiskraffinering ochförändringar i raffineringssystemet.Detta licentiatprojekt är en del av ett större projekt där olika tekniker för attförbättra energieffektiviteten har utvärderats i industriell skala på Holmen PaperBravikens pappersbruk. Licentiatprojektet är finansierat av KK‐stiftelsen, MetsoPaper och Holmen Paper, i samarbete med Mittuniversitetet.Fullskaleförsök gjordes på en av TMP linjerna vid Bravikens pappersbruk, därgran används som råvara. Studien utfördes på dubbeldiskraffinörerna i detprimära raffineringssteget. Malkurvor, med ökande specifik raffineringsenergi,gjordes vid olika raffineringstemperaturer, intensitet, massakoncentration ochproduktion. Resultat som erhållits från malkurvorna bekräftades med längrestudier på raffinörerna. Intensitetsmodeller och simuleringar utfördes av Juha‐Pekka Huhtanen från Tampere University of Technology.De erhållna resultaten visar på att energiförbrukningen till ett visst dragindexkan minskas genom att öka raffineringstrycket/temperaturen. Medraffineringstryck menas inlopp och hustryck i raffinören. Energibesparingen är iintervallet 80‐150 kWh/adt. Den största förbättringen kan uppnås vid lågaenergiinsatser. Massor producerade med högt tryck och temperatur och lägrespecifik energiförbrukning uppvisar liknande ultrastrukturella ytegenskaper sommassor producerade med lågt tryck och temperatur och hög specifik energi. Högttryck och temperaturer med hög specifik energiinsats gav en signifikant förbättringav delaminering/intern fibrillering av massafibrer. Dessa fibrer uppvisadebildningar av långa band‐liknande fibriller från fibrernas S2 skikt, i jämförelse medmassor tillverkade med lägre tryck och temperatur och lägre specifik energi.5Om raffineringen genomförs vid högt tryck/temperatur bevaras dragindexunder hela segmentlivslängden.Den specifika ljusspridningskoefficienten påverkades positivt av ökat tryck ochtemperatur. En orsak till detta kan vara högre intensitet som orsakas av minskadmalspalt.Ökad intensitet genom förändrad segmentdesign leder till stora ökningar i denspecifika ljusspridningskoefficienten. Samtidigt uppnås samma dragindex, lägrespethalt, lägre genomsnittlig fiberlängd och CSF vid samma specifikaenergiförbrukning.Förbrukningen av färskångan sänktes vid tillämning av högre tryck ochtemperatur i raffinören.

Philosophiae Doctor - PhD / The next generation of radio telescopes will revolutionize cosmology by providing large three-dimensional surveys of the universe. This work presents forecasts using the technique 21cm intensity mapping (IM) combined with results from the cosmic microwave background, or mock data of galaxy surveys. First, we discuss prospects of constraining curvature independently of the dark energy (DE) model, finding that the radio instrument HIRAX will reach percent-level accuracy even when an arbitrary DE equation of state is assumed. This is followed by a study of the potential of the multi-tracer technique to surpass the cosmic variance limit, a crucial method to probe primordial non-Gaussianity and large scale general relativistic e↵ects. Using full sky simulations for the Square Kilometre Array phase 1 (SKA 1 MID) and the Large Synoptic Survey Telescope (LSST), including foregrounds, we demonstrate that the cosmic variance contaminated scenario can be beaten even in the noise free case. Finally, we derive the signal to noise ratio for the cosmic magnification signal from foreground HI intensity maps combined with background galaxy count maps. Instruments like SKA1 MID and HIRAX are highly complementary and well suited for this measurement. Thanks to the powerful design of the planned radio instruments, all results confirm their potential and promise an exciting future for cosmology.

<p>Drawing from literature on job performance, moral intensity (Jones, 1991), and job characteristics theory (Grant, Fried, & Juillerat, 2011; Hackman & Oldham, 1976; Oldham & Fried, 2016), I propose a core feature of work that is not currently recognized or studied in extant work design research: the degree of moral imperativeness and aspiration. That is, jobs differ in how much their performance (i.e., task execution) is a moral imperative or aspiration. I first distinguish the moral imperativeness and aspiration of task execution (MITE and MATE) from related concepts such as task significance (Hackman & Oldham, 1975), prosocial characteristics of work (Grant, 2007, 2008a), and moral intensity of a task (Opoku-Dakwa, 2017, 2018). I then develop and validate a scale. In Study 1, I used job incumbents to provide empirical support that moral imperativeness and aspiration of task execution is distinguishable from related constructs, converge with theoretically-relevant constructs, and predict work criteria as experienced by job incumbents. In Study 2, I used naïve raters to judge the moral imperativeness and aspiration of work tasks at the task level to provide further evidence that they tap objective aspects of occupations.</p>

<p>FDA has long served as the front safeguard to the U.S. citizen public health, is also perceived as one of the world-leading drug regulators. Despite the tremendous efforts and progress have been made to promote the public health, FDA was criticized for putting the agency’s trust icon at stake and was questioned of its ability to serve the agency’s ultimate mission to protect the public. In the wake of the arousing concerns, FDA sought the transformation the oversight model of the medicinal products. One of the actions is to launch quality metrics program. However, this program has been unanimously opposed by the industry. Instead of the current conventional approach, which is constrained by the high dependence on industry cooperation, we try to explore</p><p>the measurement of company and product quality risk with public domain data, try to help in visualizing quality and risk. To that end, we develop conceptual frameworks for both company and product quality, examine some of the factors (education, local authority intensity, historical inspection results, physiochemical, physiological, formulation factors, etc.), further developed a warning letter and product recall prediction model with machine learning method referenced to the data analysis outcome.</p>

Many interesting physical processes produce non-interacting particles that could only be measured using the missing transverse momentum. The increase of the proton beam intensity in the Large Hadron Collider (LHC) provides sensitivity to rare physics processes while inevitably increasing the number of simultaneous proton collisions in each event. The missing transverse momentum (MET) is a variable of great interest, defined as the negative sum of the transverse momentum of all visible particles. The precision of the MET determination deteriorates as the complexity of the recorded data escalates. Given the current complexity of data analysis, a new algorithm is developed to effectively determine the MET. Several well-understood physics processes were used to test the effectiveness of the newly designed algorithm. The performance of the new algorithm is also compared to that of the standard algorithm used in the ATLAS experiment. / Graduate
