Electrical Engineering Bundle for PPC full.
Mona is a symbolic circuit analysis program capable of computing voltages and currents in terms of component variables. There simply is nothing out there so easy to use and insightful as Mona when it comes to basic linear circuit analysis for electrical engineering students and professionals wanting to freshen up. Mona is a great educational tool that students can use to verify homework and professors can use to communicate important principals in basic analog circuits.
The software is designed to run on small handheld pocket devices so you can have it with you even on labs but it also runs on virtually any PC that supports Java including Windows, MacOS and Linux. With an extensive feature list and amazing functionality, this is a piece of software electrical engineering students can't live without.
Feature set of Mona:
Mona comes loaded with useful features designed to help you understand analog circuitry, some of these include;
·Complete schematics capture front end supporting 90 degree rotation of components and multi-segment wires that allows any circuit to be drawn as found on textbooks. Supports file save and load circuit files.
·Rich list of analog components including : resistor, capacitor, inductor, impedance, infinite gain opamp, finite gain opamp, adder and multiplier (for control systems), ground, opened circuit nodes, closed circuit branch, voltage and current controlled voltage source, voltage and current controlled current source, voltage source and current source.
·Basic electrical engineering calculations : node voltage, branch current, resistance into a node and Norton/Thevenin equivalence, all performed symbolically. Values, Symbols, Imaginary numbers as well as Phasors can be associated to components.

Lisa is a "classical Feedback Control Systems" application designed to handle typical calculations in the 's' and 't' domains.
Following the tradition of Formulae 1 (our award-winning product), Lisa packs quite a bit of functionality with tremendous ease of use, providing a very attractive value proposition to potential users.
Lisa supports Bode Analysis and Design, Root Locus Analysis and Design and Time analysis. Lisa provides an interactive equation editor that communicates both way with the other 3 components (bode, root locus and time) allowing tremendous flexibility of analysis and design problems.
Lisa's main innovative feature is in its ability to graphically (and instantaneously) manipulate line approximations of transfer functions while at the same time keeping track of its real equations.
Feature set of Lisa:
Bode
- Line approximation for phase and magnitude plots that allows users to adjust an existing transfer function or completely design one from scratch. Line approximation nodes are draggable and can be manipulated by the user graphically while the system keeps track of its equation. Users can generate line approximation from s-domain equations and/or via user interface by adding/deleting/modifying nodes from the line approximation. This is a great feature not found anywhere else that not only has tremendous pedagogical value but also eases bode design in general.
- Users can add/delete real/imaginary pole(s)/zer
s).
- Multiple bode plots.
- Calculates Gain Margin, Phase Margin and Bandwidth.
- Imports equations from Equations panel.
- Exports Line approximation equations to Equations Panel.
- Line approximation of root locus allowing the user to drag, add or delete poles and zeros and instantly see a line approximation sketch featuring : poles, zeros, asymptotes, angles of arrival and departure, real axis points and breakaway points.
- Smart auto range will automatically adjust axes on plot to make it easy to see plot features.
- Users can add/delete real/imaginary pole(s)/zer
- Allows users to pick a particular K given design criteria.
- Calculates K, Wn, Alpha and Zeta.
- Imports equations from Equations panel.
- Exports Open loop and/or closed loop transfer functions to Equations Panel.
- Provides symbolic functions for Laplace transform and its inverse. This allows users to modify time equations and see its effect in the frequency domain or vice-versa. All calculations are done symbolically so users end up with equations instead of just simulated plots.
- Calculates Time delay, Time to peak, Time to rise and Time to settle.
- Smart auto range will automatically adjust axes on first plot to make it easy to see plot features.
- Supports multiple time plots.
- All plots support scrolling via navigational arrows. User can also set axis values by clicking on axis (bode) or it's name (root locus and time).
- 2D display and Interactive editing of math expressions.
- Virtual math keypad relevant to problem domain.
- Reusable history buffer.
- Multiple Undo.
- Interactive Help System featuring detailed explanations for every button/function available and sample problems.
You simply can not beat the value of this package on handheld devices and standard notebook/desktop computers. If your computer supports Java, Lisa will run fine on it.
Formulae 1 (F1) is a powerful and easy to use Computer Algebra System designed specially for the teaching and exploration of mathematics. F1 gives the user the ability to see intermediate steps of calculations as well as final answers. The step feature has tremendous pedagogical value that users will come to appreciate over and over again.
While there are several different numerical based calculator programs for PDAs, there is nothing really that comes close to the mathematical capabilites of F1. Transform your PDA into the next generation handheld Mathematics system designed to get answers and see steps. If you are a student, this is a must have application.
F1's User Interface was custom designed to optimize the use of the small screen area of the device. Most of the screen area is available to view and manipulate math expressions, unlike other calculators where most of the screen is populated by buttons.
Feature set of Formulae 1:
- Simple to use and well organized Graphical User Interface featuring tabs, buttons, palettes, command folders and extensive built-in help system with tons of sample mathematical problems.
- Fast automatic simplification of expressions containing symbols and functions.
- Correct 2D display of mathematics including proper use of symbols such as fraction divider, absolute value, radicals, derivatives, integrals, etc.
- Math Editor builds expressions graphically as they are typed providing an intuitive environment to deal with mathematics.
- Powerful command center via Go and Step. Just build a query and press Go to obtain the final answer to the query or step to obtain the next step in the calculation process. With these two commands, all the user needs to know is how to type a query (problem) in and from there on the system will solve it and show intermediate steps as required by the user automatically.
- Powerful automatic Solve facility capable of solving symbolically in one shot or via steps, equations containing absolute value, radicals, polynomials, inequalities and systems of equations.
- Main commands for factorization, evaluation (turning a symbolic expression into a number) and simplification of expressions.
- Trigonometric Functions: sin, cos, tan, csc, sec, cot, asin, acos, atan, acsc, asec and acot. Special stepwise emphasis was placed here to deal with removing extra revolutions (in radians and degrees) as well as folding trigonometric expressions in quadrants II, III and IV into quadrant I, this has great pedagogical value to students learning trigonometry.
- Logarithmic Functions: ln, log, log of base b and exp.
- Miscellaneous Functions: mixed fractions conversion, absolute value, square root, nth root, factorial, exponential notation, imaginary numbers and user defined functions.
- Calculus support: Derivatives, Integrals, Integration by Parts and Integration by Variable Substitutions. Stepwise Integration highlights automatically specific integration techniques such as using Partial Fractions expansion, long division and integration by parts or a special variable substitution.
- Matrix Support: Full Matrix Arithmetic, Row Operations and Matrix Functions including (determinant, adjoint, matrix inverse, transpose and others). Of special mention here is the stepwise calculation of matrix inverse by using row operations. The system will automatically show row operations used to inverse any matrix (even symbolic ones) and then it will perform the actual row operation. Tremendous Pedagogical value to users.
- Polynomial Support: permutations, combinations, grouping, complete the square, splitting fractions, long division and partial fractions.
- Powerful Variable and Function Isolation that allows the user to manually manipulate equations step by step.
- Easy object based graphing. Unlimited plots can be removed or added at will.
