Micrometer Simulator is an app that used to learn about how to read Micrometer device measurement result. Teacher, student or any user else can do measurement virtually before they go to the laboratory, and do measurement with real object.  With this app they no need more time to learn how to read micrometer scale, and directly can do measurement with the real object, without go to the real laboratory. Just drag and press the Micrometer Object to do measurement Virtually. You can change the virtual object that you want to measure with Change Object menu and try to read the measurement result on the Scale object. Have fun, and let try it! Get it free at: https://play.google.com/store/apps/details?id=com.priantos.micrometersimulator You can also try the game mode of this app in link below:

Caliper game is an simple game that designed to simulate how to read of Caliper measurement results. This app is one of Computational Lab of Department Physics, UB productivity app that originally purpose to increase the passion of learning about physics in Elementary Physics Lab. You can press the Caliper Image to interact with it, and learn how to measure of the different object at every task.  This game have 16 Task with different variation of measuring object, like as screw and basic object with random wide. You can also know how right your measurement result as poor, average, good or excellent by the error value at every Task.

Polynomial Calc is an app that designed to calculate any polynomial equation and to solve your polynomial equation with numerical approximation. This app is use numerical method, and the calculation is needed looping time and have an error value, but it can be predict many from of polynomial equation with single variable x. This is also one of Smart Calc Lib that have been developed by Computational Lab., Dept. of Physics, UB. The main idea of this algorithm, we called as the progressive error prediction, where is the implementation of Genetic Algorithm. With that algorithm we can do the numerical calculation that have the ability to predicted many unknown variables, many inputs value and many form of equation with small error value as well as We implement on Predicted Calc App. Just type your polynomial equations and let Polim Root find unknown x of your polynomial equation. You can get this app free at link below:

Computational Physics Laboratory, Dept. of Physics UB, develop a Android base library that implement from Genetic Algorithm Method. The library called as NeuronBox, where it's the implementation of the generation concept of Genetic Algorithm and best neuron idea from Neural Network method. This Library produced as calculator and can be found at Google Store with the link and short description as below. The main idea of the algorithm of library called as the "Progressive Error Prediction", it's a numerical method calculation, so for calculation progress need looping time and approximation error value, where is the implementation of Genetic Algorithm. With that algorithm we can do the numerical calculation that have the ability to predicted many unknown variables, many inputs value and many form of equation with small error value as we implement on Predicted Calc App. Polinom Root Free Polim Root is a free version app that can be use to calculate roots of polyno...

Computational Lab. of Departement of Physics, University of Brawijaya, Malang. initiated to made the simulator of basic beasuring tools that purposed to be used by student or anyone that will be do the laboratory experiment,. The simulator is about Caliper, Micrometer and Osciloscope. This simulator you can find free at Google Play Store with the link below:  Caliper Simulator Micrometer Simulator Osciloscope Simulator or for not advertisement and pro version you can find at Basic Measure App This applications was been made caused by reason as many of new student that do experimental laboratory need more time to learn to use Caliper, Micrometer, or Osciloscope for the first time. With this app, the student could be learn by himself before they do the real experiment. So student will be ready and do the experiment that accorded with the theme of experiment, and not distrubing by the way how to use the measurement tool. Here the preview Video of Basic measurem...

Predicted Calc is a calculator that made by android base, and use genetic algorithm to get unknown value of variables that typed on the equation.  Therefore, this app can also be use for finding root of polynomial equation, like an examples below: For example to find root of equation: x 2 -2*x-3=0 The steps is: Copy and write the equation without x and y, and with math sign operation, for example by using xo, so the equation can be writed as xo*xo-2*xo-3=0, because  x and y was used by Predicted Calc as input variables. Press calculate botton to predict one of roots. Wait until Predicted Calc, approach the best value can be reach. Because using prediction method, Predicted Calc give error result, this error show how far the prediction give best value that can be reach by your device on that calculation, another calculation could be give the different result as same as or more better error value. Predicted Calc will give the result -1 and 3 with error=0, l...

One more, Computational Lab., Dept. of Physics, UB release new android app today, 1 Juli 2015. This app called as Date Calculator and have functionality as general calculator, but with different method where the calculation is based on date data. It's that mean all math operation on this app is basically to optimize user to do math calculation accordingly date math operation. And so in this calculator we will not find minus value, because in Julian Date the minimum value is zero.   Figure 1. The main idea of Date Calculator is because mostly of us do math calculation based on date data. especially for give dateline to some project, with just type number of day that given, we need to make sure what the date is it happen. However the math operation is the basic operation like addition, subtraction , multiplication and division, but if we directly calculate manually, sometimes could be little difficult and we have to see calender to validate.  For example, like in ...
