abstract: In trading, volume is a measure of how much stock has been exchanged in a given period of time. Since every stock is distinctive and has an alternate measure of shares, volume can be contrasted with historical volume inside a stock to spot changes. It is likewise used to affirm value patterns, breakouts, and spot potential reversals. In my thesis, I hypothesize that the concept of trading volume can be extrapolated to social media (Twitter). The ubiquity of social media, especially Twitter, in financial market has been overly resonant in the past couple of years. With the growth of its (Twitter) usage by news channels, financial experts and pandits, the global economy does seem to hinge on 140 characters. By analyzing the number of tweets hash tagged to a stock, a strong relation can be established between the number of people talking about it, to the trading volume of the stock. In my work, I overt this relation and find a state of the breakout when the volume goes beyond a characterized support or resistance level. / Dissertation/Thesis / Masters Thesis Computer Science 2015

Mathematical modelling using advanced approach based on the neural networks has been applied to the control and the quality optimisation in the main processes of steelwork such as the ladle metallurgical treatment and continuous casting. Particular importance has been given to the improvement of breakout prediction system and the reduction in the rate of false alarm generated by the conventional breakout detection system. Prediction of the chemical composition and temperature of liquid steel in the ladle has been achieved by neural networks and linear model. This prediction can be considered as a soft sensor. Slab surface temperature stabilisation on the basis of the casting events has been controlled by a neural networks algorithm, that gives an improvement in the surface temperature fluctuation in comparison to the conventional control system which is based on the PID controller. Quality monitoring and classification is also achieved by a neural network which is related to the breakout detection system. This technique achieves a classification of different defects based on the different alarm signal given by the breakout prediction system. Fault detection and process monitoring is developed using neural networks modelling. All models are developed on basis of practical operating database obtained from the iron and steel industry.

This report investigates the implementation of a Deep Reinforcement Learning (DRL) algorithm for complex tasks. The complex task chosen was the classic game Breakout, first introduced on the Atari 2600 console.The selected DRL algorithm was Deep Q-Network(DQN) since it is one of the first and most fundamental DRL algorithms. To test the DQN algorithm, it was first applied to CartPole which is a common control theory problem, using values describing the system as input.The implementation was then slightly modified to process images when employed for Breakout, in which it was successful. The application received a higher score than a professional human game tester. However, work remains to be done to achieve performance similar to state-of-theartimplementations of the DQN algorithm. / Denna rapport undersöker tillämpningen av en Deep Reinforcement Learning (DRL) algoritm för komplexa uppgifter. Den komplexa uppgift som valdes var Breakout från konsolen Atari 2600. DRL-algoritmen som användes var Deep Q-Network (DQN), eftersom det var en av de första och mest grundläggande DRL-algoritmer. För att kontrollera DQN-algoritmen tillämpades den först på CartPole, vilket är ett vanligt problem från reglerteknik, med tal som beskriver systemet som indata. Implementationen var sedan aningen modifierad för att kunna hantera bilder när den användes till Breakout, i vilken den presterade väl. Applikationen fick fler poäng än en proffesionell speltestare. Det finns dock andra implemeteringar som har fått högre poäng, och mer arbete behövs för att uppnå likvärdiga resultat. / Kandidatexjobb i elektroteknik 2022, KTH, Stockholm

[pt] Este trabalho aborda uma análise do problema de interação solo-duto através de modelagem em centrífuga da movimentação lateral e axial de dutos em modelos de areia submersa. Foi quantificada a resposta do solo ante a movimentação do duto em termos de mobilização das resistências pico (breakout), da evolução das forças resistentes durante a formação das bermas, e das trajetórias de forças vertical-lateral/axial combinadas que definem uma possível envoltória de fluência. Foi adotada uma simplificação básica dos cenários encontrados comumente na prática offshore. Para tanto, foram realizadas duas séries de ensaios em centrífuga geotécnica, aplicando deslocamentos laterais e axiais controlados em dutos com células de carga horizontal e vertical. Analisou-se históricos de carregamento plausíveis de acontecer no processo de lançamento do duto. Avaliou-se a influência do relaxamento das forças verticais decorrentes do enterramento do duto na mobilização das resistências lateral e axial. Resultados típicos dos ensaios são apresentados. Foi identificada a variação da resistência mobilizada, em termos de forças de breakout e forças máximas nas bermas, em função à relação entre as forças verticais de enterramento e as forças verticais no início da movimentação do duto. Os resultados revelam superfícies de fluência parabólicas em condições de carregamento vertical e lateral/axial combinado. Foi observado que as distâncias de mobilização das resistências axiais de breakout aumentaram em relação à porcentagem de enterramento do duto (w/D) divergindo de valores estimados na prática offshore que propõem distâncias constantes. / [en] This study concerns the analysis of soil-pipeline interaction through centrifuge modelling of cyclic lateral and axial of pipeline movement in submerged sand models. Soil response related to pipeline movement was quantified in terms of breakout, evolution of resistance forces during berm formation, combined vertical-lateral/axial trajectories of forces that define a possible yield envelope. A simplification of common offshore scenarios was adopted. Two series of geotechnical centrifuge tests were accomplished by applying controlled lateral and axial movements to assess load history possible to occur in the process of pipeline laying. The influence of vertical stress relaxation due to pipeline embedment was assessed relative to vertical forces in the instance of the movements. Typical assay results are related. The variation of the mobilized resistance was identified in terms of breakout forces and maximum forces in the berms relative to vertical force history due to pipeline embedment. The results revealed parabolic yield surface in combined vertical-lateral/axial loading conditions. The mobilized distances of the breakout axial resistance increased in relation to pipeline embedment percentage (w/D) diverging from values estimated in offshore practice that propose constant distances.

A numerical technique based on the theory of plasticity is developed to predict an optimum failure surface generatrix and concrete breakout capacity of single anchors away from edges under tensile loads. Concrete is regarded as a rigid, perfectly plastic material obeying a modified coulomb failure criteria with effective compressive and tensile strengths. The failure mode is idealized as an assemblage of two rigid blocks separated by failure surfaces of displacement discontinuity. Minimization of the collapse load predicted by the energy equation produces the optimum shape of the failure surface generatrix. A simplified solution is also developed by approximating the failure surface as two straight lines. The effect of different parameters on the concrete breakout capacity of anchors is reviewed using the developed mechanism analysis, ACI 318-05, and test results of 501 cast-in-place and 442 post-installed anchor specimens. The shape of failure surface and concrete breakout capacity of anchors predicted by the mechanism analysis are significantly affected by the ratio between effective tensile and compressive strengths of concrete. For anchors installed in concrete having a low ratio between effective tensile and compressive strengths, a much larger horizontal extent of failure planes in concrete surface is predicted by the mechanism analysis than recommended by ACI 318-05, similar to test results. Experimental concrete breakout capacity of anchors is closer to the prediction obtained from the mechanism analysis than ACI 318-05. ACI 318-05 provisions for anchors sharply underestimate the breakout capacity of cast-in-place and post-installed anchors having effective embedment depths exceeding 200 and 80 mm (7.87 to 3.15 in.), respectively, installed in concrete of compressive strength larger than 50 MPa (7250 psi).

<p>Recent experiments have highlighted the efficacy of post-installed reinforcement in enhancing the capacity of groups of  bonded anchors undergoing concrete breakout failure mode. This technique is particularly useful to enhance the performance of anchorages installed in members of limited dimensions such as beams and columns. This thesis presents the results of corresponding numerical investigations on bonded anchor groups in concrete strengthened with post-installed supplementary reinforcement subjected to tension loads. The study is conducted using the 3D Finite Element (FE) approach. The constitutive law of concrete is the microplane model with relaxed kinematic constraint. The interface between anchor or reinforcement and concrete is modeled with two-node bar elements, which are assigned with corresponding bond-stress slip characteristics. The proposed FE approach is validated against experimental results available in the literature by comparing load-displacement behavior and failure mode. </p> <p>The validation incorporates anchor groups with different configurations of post-installed supplementary reinforcing steel bars. The numerical investigations provide a deeper insight into the detailed behavior of anchor groups with post-installed reinforcement through the visualization of crack patterns, stress flows, and strain development. The results show that the post-installed rebars can lead to a significant increase in the performance of post-installed anchorages, and the load increase depends on the number and arrangement of rebars and the failure mode of the system. </p> <p>Lastly, the thesis presents a parametric study on strengthened anchor groups with post-installed rebars in narrow reinforced concrete (RC) members under various configurations. These simulations mimic anchorages used for seismic retrofitting beam-column joints in RC structures using a fully fastened haunch retrofit solution. Due to the limited width and depth of beams and columns, the capacity of the anchorages is often the weakest link in such retrofitting methods. The results from the FE study indicate that the post-installed supplementary reinforcement can be an efficient solution for upgrading the performance of post-installed anchorages in such retrofitting techniques.</p>

Syftet med studien är att undersöka lärare samt studenters distanserade gruppdiskussioner inuti Zoom’s funktion breakout-rooms, samt hur studenternas engagemang följaktligen har påverkats. Studien är grundad i tre semistrukturerade fokusgrupper gjorda med studenter samt lärare med erfarenhet av distanserade gruppdiskussioner inuti breakout-rooms. Utifrån det empiriska materialet från fokusgrupperna framgår det tydligt att respondenterna till en stor del fokuserar på funktionalitet, flexibilitet samt sociala relationer och kameraanvändlighet. Utifrån det empiriska materialet framgår det att det funnits förmåner i form av en enkelhet och smidighet för lärarrespondenterna att utforma gruppdiskussioner, samt flexibiliteten som gett studenterna en ökad frihet. Emellertid framgår det utifrån studentrespondenterna att uppfattningen av distanseringen grundar sig i försämrad kommunikation med lärare och studenter, svårigheter i form av distraktioner samt en försämrad relation till sina klasskamrater, vilket följaktnings har påverkat studenternas engagemang negativt. / The purpose of the study is to examine teachers' and students' distant group discussions within Zoom's function breakout rooms, and how the students' involvement has consequently been affected. The study is based on three semi-structured focus groups made with students and teachers with experience of distant group discussions inside breakout rooms. Based on the empirical material from the focus groups, it is clear that the respondents largely focus on functionality, flexibility as well as social relations and camera usability. Based on the empirical material, it appears that there have been benefits in the form of a simplicity and flexibility for the teacher respondents to design group discussions, as well as the flexibility that has given the students increased freedom. However, it appears from the student respondents that the perception of distancing is based on impaired communication with teachers and students, difficulties in the form of distractions and a deteriorating relationship with their classmates, which consequently has affected students' commitment negatively.
