Quality Window v5.0.667
An SQC/SPC/Event Analysis tool designed for use on the factory floor. The intuitive presentation of data uses product/customer specifications to help "find and fix" reasons for process/product variation as well as helping in the analysis and understanding of failures such as downtime and defects, tailored to your specific needs. Data collection can be manual or assisted through interfaces to PocketPC's, scales, gauges or even PLC's.
Regression Analysis and Forecasting
The Multiple Regression Analysis and Forecasting model provides a solid basis for identifying value drivers and forecasting business plan data. While it utilises a range of commonly employed statistical measures to test the validity of the analysis, results are summarized in text for ease of use. Once relationships have been identified, forecasting can be accomplished based on a range of available methodologies.
RVal
Resistors are normally supplied in ranges that have 6, 12, 24, 48, 96 or 192 values per decade. RVal helps you select the best values to produce a given ratio or difference, to connect in series or parallel to produce an exact value, the nearest preferred value to any given value, find the preferred value required in parallel with an existing resistance to produce a desired value or display a list of the values in one decade of any range.
Scientific Advantage Calculator
Scientific Advantage? is a Unit Aware? calculator that lets you work with feet-inch-fraction dimensional values and includes advanced math functions, automatic solvers, and much more. Unit Aware? means that you can effortlessly compute with units (not just convert). It also has great options like algebraic and RPN entry, customizable buttons for unit entry, and display precision options. Available for both Windows and Pocket PCs.
Scientific Letter
Scientific Letter is an original mail program that allows you to create messages with complex equations. The equation editor used in the mailer allows you to create complex letters, including equations, at just about the same speed as typing a normal letter. Recipients of letters from SciLetter who use other mailers will see the message text with equations included in it as a LaTeX notation. This mailer makes the exchange of complex ideas simple.
Sevana Shopping Cart Analyzer
Sevana Shopping Cart Analyzer is a perfect tool for the so called Market Basket Analysis. The analysis itself is one of the most common and useful ways for marketing analysis.
SEVENPAR (English)
Purpose of the program SEVENPAR is to produce a set with seven Helmert transformation parameters valid for an specific area, with which then arbitrary points of the area can be transformed from one coordinate system into another with high accuracy. The seven Helmert parameters are calculated in the three most usual standards. Those are the Coordinate Frame Rotation, the Position Vector Transformation and the European Standard ISO 19111.
