Droid Tesla Pro app apk 4.04 android free download

DroidTesla is a simple and powerful SPICE engine.
SPICE is an acronym for Simulation Program with Integrated Circuit Emphasis
and was inspired by the need to accurately model devices used in integrated circuit design.

DroidTesla simulator solves basic resistive circuits using Kirchoff’s Current Law (KCL)
in much the same way a student in a circuits class would,the simulator systematically forms a matrix in accordance
with KCL and then proceeds to solve for the unknown quantities using various algebraic
techniques such as Gaussian elimination and sparse matrix techniques.

For non-linear components, such as the diode and BJT ,DroidTesla engine searching for the approximate solution by making an initial guess at an answer
and then improving the solution with successive calculations built upon this guess.
This is called an iterative process.DroidTesla simulation uses the Newton-Raphson iterative algorithm
to solve circuits with non-linear I/V relationships.

For reactive elements(capacitors and inductors),the DroidTesla uses numeric integration methods to approximate the state of the reactive elements as a function of time.
DroidTesla offers the Trapezoidal(I'll add a GEAR method later) integration methods to approximate the state of the reactive elements.
Although for most circuits, both methods will provide almost identical results,
it is generally regarded that the Gear method is more stable, but trapezoidal method is faster and more accurate.

SD Maid Pro- System cleaning tool app apk 2.0.3.0 android free download

This is a powerful tool! Use at own risk!

NEW:
THIS APP IS INTENTED FOR ROOTED DEVICES!
Without root, functionality is limited as SD Maid won't have access to all necessary directories.
This is a powerful tool! Use at own risk!

Nobody is perfect and android neither.
Apps you have already deleted sometimes leave data behind.
The system constantly creates logs, crash reports and debug files you don't really need.
The market leaves temporary files of downloaded apps behind.
Lets not go on here...

Why not get a maid to clean it all up? SD maid will help you keep your device neat, clean and tidy for you

!

Choose a tab, press check and then either click a single item to delete or press the clean all button. It's just that easy.

The explorer is a full fledged filemanager, use it to crawl through your androids files.

You can use the searcher to open/delete or rename files (wildcards are supported as is searching inside files).

The corpse finder searches your device for dormant directories and compares those to the list of installed applications.

The system cleaner scans the devices known directories with unnecessary files.

SD Maid is constantly being developed and is designed very carefully.

Due to the vast amount of android devices it might not work perfectly on everyones device, but i'm working hard to get it there. If you have problems on your device contact me (support@thedarken.eu) and i will try to fix your problem in the next version.

v2.0.2.3(210)
- Fixed startup crash on unrooted devices, sorry :-(

v2.0.2.2(209)
- Added support for x86 architecture processors
- Improved JellyBean compatibility
- Performance/Memory improvements
- Fixed issues with deleting huge file amounts
- Various small fixes & tweaks
Full changelog @ http://goo.gl/c2pc9
Questions? Mail me! :-)

PerfectShot Unlimited app apk 1.6.5 android free download

By providing you the most advanced assistances, PerfectShot helps you eliminate chances of imperfect shots and improve your efficiency so you are able to take better shots and have better chance of capturing precious moments.
The main features include:
* Full auto mode that detect vibration of phone and automatically choose the perfect moment to take the picture. All you need to do is to compose and then hold your phone still. This removed the need of touching the screen button when you take a picture which increased the chance of camera shake, and released you from using both hands. So enjoy blur-free shots and single hand operation! There are also other modes like manual and timer for your convenience.
* Best virtual horizon assistance in the market! In addition to horizon line, it also gives you 3D guide lines that tells you roll and pitch positioning of your phone. Say goodbye to tilted photos!
* AR assisted focus & metering area selection! The area you select stays the object and update itself after you re-compose the picture! (Works on supported ICS devices only because not all phones support focus and metering selection)
* Extreme optimisation provide fast startup time that is on par with the ICS native camera app, as well as a minimum footprint. So you will be ready to shoot faster. It is also seamlessly integrated into Android system that you can set it to take over system camera and start it from lock screen. You can also access photos taken by PerfectShot in the system gallery and share them whatever way you want.
* Innovative UI design that helps you change your setting fast and accurately.
* One touch focus & metering area selection.

What's in this version: (Updated : May 5, 2013)
Fixed crash on 2.3 devices
Remember video quality setting
