After the fixture was sealed within the bell jar, the Margherita 2 underwent bakeout and a test seal on a one-inch tile. Following this small success, a larger project of sealing a larger tile during cesiation launched in the final week of the author's summer in the LAPPD Lab. Central to the ability to control these processes is the ability to monitor temperatures, pressures, and RGA plots as well as adjust heating inputs accurately and timely. This report documents the heating procedures, basic sealing cycle, and plotting past events or in real-time with the Margherita 2 infrastructure.

In deze handleiding worden twee technieken beschreven voor visuele cryptografie. Bij de eerste techniek worden twee transparanten met schijnbaar willekeurige patronen van zwarte blokjes over elkaar geschoven om een geheime afbeelding tevoorschijn te laten komen. De tweede techniek gebruikt twee afbeeldingen in grijstinten die transparant over elkaar geschoven worden om een geheime afbeelding op te roepen. De enige voorkennis die nodig is om deze technieken te kunnen uitvoeren, is het gebruik van een rekenblad (hier: Excel) en van een fotobewerkingsprogramma.

Projections are a "prescribed" part of structural analysis and visualizations, with the change in day and age numerous computer applications have been written to aid this. Most of them have taken care in explaining and elaborating the mathematical and programmatic aspects of their implementation. These applications and/or programs all have attained a robust and well accepted status in the field. The previously developed programs have mostly taken a traditional approach in code and design, i.e. the use of programming languages like C/C++, Fortran, Java, Python or packages like Matlab, Mathematica etc. The Open Source Web application discussed here takes up the task of removing system dependencies of the code by the use of JavaScript, the language of the web-browsers, for the entirety of the programming, and improves portability of the output by directly plotting into Scalable Vector Graphics (SVG).

Description of results of fieldwork at Pocono Environmental Education Center with students from Malcolm X Shabazz High School, May 2005.

В данной работе решается задача моделирования поверхности открытого океана в реальном времени с использованием GPU для вычисления поля высот.

This study aims to analyze what altmetric factors affect the success of a Kickstarter campaign. This project was created by two high school students for the Big Data Challenge.

Laboratory where LEX is compared to C

Trabalho experimental de determinação da Constante de Planck e do comportamento de Corpo Negro para um filamento de Tungstênio a partir da determinação de temperatura por resistência e por radiação eletromagnética.

The impact crater of a small metal ball of 63.7 grams (0.0637kg) is dropped from 8 different heights, ranging from 0.20m to 0.90m was observed. A mean was measured for the craters diameter. Using the equation E=mg$\Delta$h given that we have m, and g is a constant of 9.81 we can find the kinetic energy of the ball on impact. The relationship between crater diameter, D, and impact energy, E, is given by D=kE$^n$ where K is constant and n is found by the gradient of the graph and is also constant. This can be modified to give $\log D = n\log E + \log k$.
