Chemistry Resources

The City College Chemistry Web Resources Page, CUNY.edu. is a great chemistry resource and one that we highly recommend to students, teachers, and researchers alike.

We are happy to learn that they have added to the Computational category our Hydrocarbons Parser

http://www.minerazzi.com/tools/hydrocarbons/parser.php

Not trying to compete with such a large chemistry resource site, but we want to let you know that we will soon be added several new chemistry tools to the http://www.minerazzi.com/tools section, some inspired in the CUNY resource page, and others oriented to data retrieval.

The following is a list chemistry tools that we have so far developed.

Currency Exchange Rates Tool

Tags

This is a new O2M data conversion tool available at

http://www.minerazzi.com/tools/currency/converter.php

It is a practical example of using one-to-many (O2M) mapping for the handling of resources from an external server.

In this case we summon a remote server at the European Central Bank (ECB) which handles currency exchange rates. Reference rates are updated at around 16:00 CET by ECB so you get the most recent exchange rate results.

Just input a value and press the Enter key. No need to mess over and over with annoying pull-down menus or remember currency acronyms.

 

Number Base Converter

This is a new tool, available at

http://www.minerazzi.com/tools/number-base/converter.php

Now you can easily convert numbers, from one to many number bases, or encode text with this one-to-many (O2M) mapping tool. A nice implementation of our O2M algorithm. Just input a value and press the Enter key.

The tool supports the most common base62 implementations out there, allowing users to convert from base2 to base62. Many applications are possible.

Volume Converter

Convert volume units like SI, US, British, and more with this one-to-many (O2M) mapping tool.

No need to mess over and over with annoying pull-down menus. Just input a value and press Enter key.

Good Keywords are far from Poisson

Just a reminder on how we can model good keywords:

Poisson Mixtures: Poisson mixtures fit the data better than standard Poissons

ftp://ftp.cis.upenn.edu/pub/datamining/public_html/ReadingGroup/papers/church-poisson.pdf

Inverse Document Frequency: A Measure of Deviation from Poisson: Low frequency words tend to be rich in content, and vice versa. But not all equally frequent words are equally meaningful.

Trigonometric Converter Tool

Trigonometric Converter Tool

This is a new mathematical tool, available at

http://www.minerazzi.com/tools/trigonometric/converter.php

The tool uses our design pattern algorithm for one-to-many calculations, allowing users to compute at once degrees, gradians, radians, cosines, sines, tangents, and more.

To use the tool, just input a value and press Enter key. No need to mess over and over with annoying pull-down menus.

A huge advantage of our one-to-many algorithm for building online calculators is that every field accepts input values, transparently recalculating all other field values.

Thus given N number of input fields, the tool works as N number of separate mapping tools. This is done without having to hard code specific functions for specific mappings of variables.

For instance, want to know all other trigonometric field values for a given field value like a cosecant, gradian, tangent, or sine value? No problem, the tool does the work for you on the fly.

Researchers, teachers, students, or anyone that must handle slope calculations can use the tool.

Improving the Temperature Converter Tool

Tags

, , , , , ,

We have improved and expanded the Temperature Converter tool, available at

http://www.minerazzi.com/tools/temperature/converter.php

The tool now processes a total of 71 temperature scales, including cooking temperature scales as well as the old and rare ones from the 1700s and 1800s.

This is a practical application of our design pattern algorithm for data conversion.

Data conversion made easy.

Temperature Converter Tool

This tool is another application of our unit converter design pattern described before. It uses a simple function that recursively switches between temperature conversions. No need to hard code over and over specific scales. It can be modified to include all sort of temperature scales.

Convert units like Celsius, Kelvin, Fahrenheit, Rankine, and others with this tool, available now at

http://www.minerazzi.com/tools/temperature/converter.php

6-17-2016 Update: The tool now works with a total of 71 temperature scales (yep, the very old and rare ones included).
