JetWeb: A WWW Interface and Database for Monte Carlo Tuning and Validation
A World Wide Web interface to a Monte Carlo validation and tuning facility is
described. The aim of the package is to allow rapid and reproducible
comparisons to be made between detailed measurements at high-energy physics
colliders and general physics simulation packages. The package includes a
relational database, a Java servlet query and display facility, and clean
interfaces to simulation packages and their parameters.Comment: See http://jetweb.hep.ucl.ac.uk for further informatio
ViBe (Virtual Berlin) - Immersive Interactive 3D Urban Data Visualization - Immersive interactive 3D urban data visualization
The project investigates the possibility of visualizing open source data in a 3D interactive virtual environment. We propose a new tool, 'ViBe'. We programmed 'ViBe' using Unity for its compatibility with HTC VIVE glasses for virtual reality (VR). ViBe offers an abstract visualization of open source data in a 3D interactive environment. The ViBe environment entails three main topics a) inhabitants, b) environmental factors, and c) land-use; acting as representatives of parameters for cities and urban design. Berlin serves as a case study. The data sets used are divided according to Berlin's twelve administrative districts. The user immerses into the virtual environment where they can choose, using the HTC Vive controllers, which district (or Berlin as a whole) they want information for and which topics they want to be visualized, and they can also teleport back and forth between the different districts. The goal of this project is to represent different urban parameters an abstract simulation where we correlate the corresponding data sets. By experiencing the city through visualized data, ViBe aims to provide the user with a clearer perspective onto the city and the relationship between its urban parameters. ViBe is designed for adults and kids, urban planners, politicians and real estate developers alike
Timaeus on Color Mixture
Now with extra footnotes, by editorial demand! Final version accepted by Oxford Studies in Ancient Philosophy.
This essay consists in a trick and a potential insight. The trick consists in a minimalist interpretation of color mixture. The account of color mixture is minimalist in the sense that, given certain background assumptions, there is no more to Timaeus’ account of color mixture than the list of the chromatic pathēmata and the list of how these combine to elicit perceptions of all the colors. The only potential controversial elements of the minimalist interpretation are the relevant background assumptions and the interpretation of the chromatic pathēmata. The potential insight concerns a motive that Plato, in the guise of Timaeus, may have for presenting an account of color mixture. Specifically, I shall argue that on the minimalist interpretation, Plato may be read as reconciling the Democritrean four color scheme with an older tradi- tion where white and black are the fundamental chromatic opposition. As we shall see, this bears on the interpretation of the chromatic pathēmata
Determination of nanoscale ferroelectric domain distribution in multilayer piezoelectric actuators
Caratterizzazione in scala nanometrica della distribuzione di domini ferroelettrici in attuatori piezoelettrici multistrato, utilizzati negli iniettori dei motori diesel. Le analisi sono state fatte attraverso la tecnica: Piezoresponse Force Microscopy (PFM). Essa consiste in un microscopio a forza ionica (AFM),in cui viene applicata una differenza di potenziale alla punta che entra in contatto con il materiale.ope
Localized Ferromagnetic Resonance in Inhomogeneous Thin Films
The effect of sample inhomogeneity on the ferromagnetic resonance linewidth is determined by diagonalization of a spin wave Hamiltonian for ferromagnetic thin films with inhomogeneities spanning a wide range of characteristic length scales. A model inhomogeneity is used that consist of size D grains and an anisotropy field Hp that varies randomly from grain to grain in a film with thickness d and magnetization Ms. The resulting linewidth agrees well with the two-magnon model for small inhomogeneity, HpD « πMsd. For large inhomogeneity, HpD » πMsd the precession becomes localized and the spectrum approaches that of local precession on independent grains
Document Comparison Based on the Color Scheme
Tato práce pojednává o porovnávání webových dokumentů na základe jejich barevného schématu. Zaměřujeme se na problematiku získávání barevné schémy, pro ktorou byly navrženy dvě metody spracování dokumentu, obě využívajíci knihovnu CSSBox [1]. Dále je také představen návrh normalizace dokumentu, která získavání barevného schématu předchází. Její hlavním cílem je identifikovat a zjednotit možný promněnlivý obsah zkoumaného dokumentu, aby neovlivňoval výsledky nežádoucím spůsobem. Řeší se také implementace těchto navrhovaných postupů do knihovny, která byla v závěru práce testována na vzorové sade webových dokumentů.This paper proposes the method of web document comparison based on the color scheme. It focuses on issues of color scheme retrieving. There are suggested two methods that are using CSSBox library [1]. Also, a suggestion for a document normalization is introduced. Its main goal is to identify and unite possible dynamic content of given document which could negatively affect results of retrieving. Suggested procedures are implemented in the library. It was tested on a set of web documents.

Aesthetic Preference Prediction in Interior Design: Fuzzy Approach
Interior design is all about creating spaces that look and feel good.
However, the subjective nature of aesthetic preferences presents a significant
challenge in defining and quantifying what makes an interior design visually
appealing. The current paper addresses this gap by introducing a novel
methodology for quantifying and predicting aesthetic preferences in interior
design. Our study combines fuzzy logic with image processing techniques. We
collected a dataset of interior design images from social media platforms,
focusing on essential visual attributes such as color harmony, lightness, and
complexity. We integrate these features using weighted average to compute a
general aesthetic score. Our approach considers individual color preferences in
calculating the overall aesthetic preference. We initially gather user ratings
for primary colors like red, brown, and others to understand their preferences.
Then, we use the pixel count of the top five dominant colors in the image to
get the color scheme preference. The color scheme preference and the aesthetic
score are then passed as inputs to the fuzzy inference system to calculate an
overall preference score. This score represents a comprehensive measure of the
user's preference for a particular interior design, considering their color
choices and general aesthetic appeal. We used the 2AFC (Two-Alternative Forced
Choice) method to validate our methodology, achieving a notable hit rate of
0.7. This study can help designers and professionals better understand and meet
people's interior design preferences, especially in a world that relies heavily
on digital media.Comment: Submitted to IEEE conference for consideratio
