The research tries to find out if there are differences, and on the other hand, similarities between different districts in Helsinki if the financial and educational status of the residents are compared. The main research question is; are there some districts in Helsinki that have a risk to segregate in terms of poor financial and educational status of the residents? Previous researches related to this topic were mainly related to either educational segregation or economic segregation but there is a lack of researches which concentrate on the both aspects at the same time, and take also bad credit history into consideration. This study is based on three different open data sets, two datasets from Paavo and one from Suomen Asiakastieto. In order to find out if there is segregation based on the average income, education level and bad credit history we use clustering analysis and especially dendrograms to analyze the data. In this study dendrograms are used for hierarchical cluster analysis. All of the dendrograms are created in IBM SPSS Statistics 22 -program. The results derived from two dendrograms and a proximity matrix created indicate that in general all of the areas in Helsinki are quite similar with each other. However, the dissimilarity between the extremities is eminent. ItemAvokadon sävyjä - puretusaineen, lämpötilan ja materiaalin vaikutus tekstiilin värjäämisessä avokadon kuorilla ja siemenillä(Aalto University, 2023) Mäki-Lohiluoma, Annika; Muotoilun laitos; Department of Design; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and Architecture ItemBiomass Gasification(Aalto University, 2011) Kouhia, Mikko; Energiatekniikan laitos; Department of Energy Technology; Insinööritieteiden korkeakoulu; School of EngineeringThere is great interest in the utilization of biomass in high efficiency power generation and in the production of high quality synthetic fuels and chemicals. Gasification, among biochemical conversion, is one way to achieve this goal. In this report the operational principle of gasification is reviewed, an analysis of different biomasses is presented and the main gasifier types are examined. The product gas composition, cleaning and utilization are examined and the commercial status of gasification is studied. There are many ways to gasify biomass, but the most common way in medium-to-large scale is to use atmospheric circulating fluidized bed gasifiers; downdraught fixed bed gasifiers are used in a smaller scale. Gasification has not yet achieved extensive usage, but it is likely to be utilized increasingly in the future as an environmentally friendly way to produce power, fuels and chemicals. ItemBiomuovit kuorirakenteena -Biomuovien vertailu vedenpuhdistimen kuorirakenteeksi(Aalto University, 2015) Leppälä, Eetu; Muotoilun laitos; Department of Design; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and Architecture ItemBiomuovit kuorirakenteina -Biomuovien vertailu vedenpuhdistimen kuorirakenteeksi(Aalto University, 2015) Jokinen, Eeva; Muotoilun laitos; Department of Design; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and Architecture ItemBiopohjaisten 3D-tulostettujen materiaalien läpikuultavuus(Aalto University, 2022) Runila, Sampsa; Muotoilun laitos; Department of Design; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and Architecture ItemCapturing Higgs boson pairs in the CMS hardware trigger using muon-enriched jets(Aalto University School of Science, 2022) Salmi, Onni; Teknillisen fysiikan laitos; Department of Applied Physics; Helsinki Institute of Physics; Fysiikan tutkimuslaitos; Perustieteiden korkeakoulu; School of ScienceAfter the concluding discovery of the Higgs boson by CERN at the Large Hadron Collider(LHC) 10 years ago, the interest of high-energy particle physics community has turnedto probing the limits of the Standard Model in the search for new physics. StandardModel predictions, such as Higgs boson self-interaction, and the related Higgs bosonpair production, are interesting in this regard. If the physical parameters related to theHiggs boson pair production, derived from particle collision data, differ in a statisticallysignificant way from the current theoretical predictions, then Beyond the Standard Modelphysics are present. As such, more Higgs boson pair data needs to be obtained in order todraw more reliable conclusions on the parameter values. The Compact Muon Solenoid (CMS) experiment, located at the LHC, detects collisiondata from the LHC proton-proton collisions. Due to the high collision rate, limited readoutand finite data storage capacities, only a fraction of the collision data may be kept foranalysis. These problems are tackled at the CMS using a data filtering system called thetrigger system, which uses various algorithms to discern interesting collision events frombackground and capture them. In addition, since Higgs boson pair production is about1000 times less frequent than single Higgs production, there is a need for precise andcompetent trigger algorithms targeting these kind of events. In this report, a new hardware trigger algorithm for the capture of Higgs boson pairsobserved at the CMS experiment is developed and analyzed. This algorithm makes useof charged elementary particles, muons, produced inside b-quark jets. These are the so-called muon-enriched jets. Prior to the performance analysis of the algorithm, the relevant theoretical aspects related to Higgs boson pair production are presented shortly, after which a cursory overview of the CMS detector is given, followed by algorithm design considerations. Improvement of 5.5% compared to old algorithms at an additional trigger rate of 1.4 kHzis obtained. ItemThe Effect of Energy Classifications on Housing Prices(Aalto University, 2015) Häyrynen, Jenna; Katainen, Anna; Rantala, Emmi; Seppälä, Maija; Seppälä, Veera; Sperling, Ella; Virtanen, Laura; Maankäyttötieteiden laitos; Department of Real Estate, Planning and Geoinformatics; Game in Urban Planning; Insinööritieteiden korkeakoulu; School of EngineeringPrevious researches have provided contradictory results on the effect of energy classifications. It seems that the effects are limited only to the highest energy classifications (A & B) while the lowest classifications seem to have little or no effect, suggesting that the housing prices are consisted of completely different factors than this. The methods for this study are literature review in addition to a regression analysis using available open data. Our regression model supported the previous results but also indicated the need to perform further research on the topic and develop the existing model by all odds, e.g. increasing the amount of variables or changing the current ones. ItemEsitutkimus lasijauheen hiukkaskoon ja -muodon merkityksestä 3D-tulostamisessa(Aalto University, 2015) Saarelainen, Tuuli; Muotoilun laitos; Department of Design; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and Architecture ItemEvaluating the viability of Serpent in Passive Gamma Emission Tomography (PGET) radiation transport simulations(Aalto University School of Science, 2021) Kähkönen, Topias; Teknillisen fysiikan laitos; Department of Applied Physics; Perustieteiden korkeakoulu; School of SciencePassive Gamma Emission Tomography (PGET) has been developed for verification of spent nuclear fuel. To reliably detect missing or substituted fuel pins, verification processes with advanced image reconstruction and classification algorithms are developed. High-fidelity PGET simulations could provide valuable information for the development, and they need accurate modelling of spent nuclear fuel, gamma-radiation, and detector response. This thesis studies the viability of Monte Carlo particle transport code Serpent for PGET modelling, and the objective is to evaluate the viability of gamma-radiation transport in this application. A two-phased analog photon transport was used to simulate flux sinograms. To meet the available time-frame, the transport was divided into two consequent phases and it was benchmarked against a normal one-phased photon transport. The method was consistent with the reference calculation and an efficiency improvement of several factors was obtained. Results were visualized as flux sinograms, from which filtered back projection reconstructions were performed. Simulated reconstructed images were compared to experimental data to qualitatively estimate the performance of the simulation. Results of the simulations were physically sensible, but the framework has to be developed further. To have a fully capable simulation framework, the performance of the radiation transport has to be further increased to make it suitable for simulations of large populations of flux sinograms. The detector response was not simulated in this study, and it has to be implemented to obtain realistic results. Furthermore, once the framework is ready, the simulation has to be validated against other codes or experimental data. ItemGamification of Education: Cities Skylines as an Educational Tool for Real Estate and Land Use Planning Studies(Aalto University, 2015) Haahtela, Pyry; Maankäyttötieteiden laitos; Department of Real Estate, Planning and Geoinformatics; Insinööritieteiden korkeakoulu; School of EngineeringComputer games and other simulations have for a long time been used as a teaching method all around the world. They give a comprehensive, but simplified view of the reality to students with a hands-on approach to problems. Games as a teaching method offer competitiveness and a chance to see the results of decision-making in real time. These elements offer a different kind of inner motivation to learning, which usually is highly welcomed among students. Computer games give a contrast to the everyday not-so-interactive class teaching, and therefore have gained high popularity in schools and universities as a method for engagement.Cities Skylines is a city planning game that offers a simplified city planning experience, but also a surprisingly in-depth understanding of a city and its various functions. Alas, the planning system in the game is streamlined and does not include a realistic view of a city planning process with its multiple participants and developers. However, the city as a functioning system is well modeled and has some real potential for educational purposes. As a stand-alone game Cities Skylines does not fully meet the requirements for an educational game in the field of real estate or city planning. Nonetheless, the game is an exceptionally well developed platform and supports plethora of modifications. With a select few, well-thought modifications, the game would support educational uses, especially city planning problem solving using scenarios. ItemHäivähdys mustaa - yhdistelmävärjäyksen ja puretteiden vaikutus mustan luonnonvärin tuottamisessa(Aalto University, 2022) Johansson, Pia; Muotoilun laitos; Department of Design; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and Architecture ItemHaljenneita pisaroita – kuroutuva lasite keramiikan teksturoijana(Aalto University, 2021) Prami, Sandra; Muotoilun laitos; Department of Design; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and ArchitectureTiivistelmäMateriaalitutkimuksessa Haljenneita pisaroita – kuroutuva lasite keramiikan testuroijana etsitään kuroutuvan lasitteen reseptejä, joita voitaisiin hyödyntää taide- ja käyttökeramiikan koristeluun. Lähtökohtina ovat aikaisempien lasitekokeiden herättämät kysymykset ja halu saavuttaa kiinnostava efekti. Tarkoituksena oli löytää lasitteita, jotka tekisivät esineen pinnalle paksuista, pyöreäreunaisista paloista muodostuvan maton. Tutkimusmenetelmänä oli kokeilu: uudet reseptit syntyivät sattumanvaraisesti valmiiden, kerättyjen reseptien ainesosien suhteita muuntelemalla. Lähdemateriaalina ovat nettilähteistä ja henkilökohtaisesti saadut lasitekoetulokset, ja lopputuloksia ja niiden syitä tarkastellaan Airi Hortligin tutkimusten ja nettilähteistä kerättyjen tietojen perusteella. Tutkimustuloksena syntyi 24 erilaista kuroutuvaa lasitetta, joiden tekstuurit vaihtelevat terävistä sirpaleista kiiltäviin lasitepisaroihin. Lasitteet ovat yhtä lukuunottamatta käyttökelpoisia vaakapinnoilla, mutta jatkotutkimusta tarvittaisiin jotta selviäisi, miten herkästi kappaleesta irtoavat lasitteet käyttäytyvät pystysuorilla pinnoilla. Lasitteiden kemia on loputon suo, mutta tutkimus opetti muutaman ainesosan tai niiden yhdistelmän lasitteeseen tuottaman lopputuloksen, ja oli hyvä aloitus lasitteiden ymmärtämiselle.
