How to show Hidden System Files and Folders on Flash Drives

Computer viruses are programs that copy themselves automatically and may destroy
your files. One of the effect of a virus on a usb flashdrive is turning all its contents
to Protected Operating System Files so that if you insert it to a computer, you can't
see any files inside because it is hidden. Showing the hidden files on the folder
options is not enough, you have to uncheck the 'Hide Protected System Files' option
as well. But this will not solve the problem. You can only see your files temporarily.
To overcome this, follow the instruction below.

1. Open command prompt.
2. Type:    attrib -S -H G:\*.* /S /D /L

* This will unset the attribute "Protected Operating System Files" on the files from a usb
  flashdrive on drive 'G:'.

Structural analysis for vertical concrete canal linings.

Assumptions:
1. No water inside the canal and the embankment outside
is up to the top bank of the canal.
2. Soil is saturated.

Procedure of analysis:

1. Compute for pressure at canal bottom using the formula:
         (1-sin(A))
Ph = ----------- x SoilWeight x CanalHeight
 (1+sin(A))
A = Angle of internal friction of soil

Rankine's Earth Pressure Theory

Rankine's earth pressure theory is widely used in analyzing the lateral pressure exerted by earth to a vertical wall (e.g. Retaining Wall) as long as it meets certain assumptions used in this theory.
Assumptions are the wall should be vertical and the friction resistance between the wall and the soil is neglected and the soil should be granular.

RC Beam Design

Here is a simple excel application for designing a reinforced concrete beam. This
uses USD.

Elevated Flume Design

This is a console application I wrote for the design and analysis of elevated flumes (used for conveying water). This has 3 parts,
1. Hydraulic Analysis
2. Structural Analysis and
3. Stability

Please post questions about the program if there is something you couldn't understand while I'm working on the documentation of the application.

Here is a sample screenshot of the project:

Inverted Siphon

This is a program I made for designing siphons with rectangular sections.
Kapain nyo na lang muna habang di ko pa nagagawa documentation.

Import Terrain Surface From Google Earth to Autocad Civil 3D

Well as the title says we will input contours from google earth autocad civil 3D.
First, you will need to have Autocad Civil 3D and Google earth installed in your system and an internet  connection as well. First go to google earth and zoom in to areas that you're insterested in getting the terrain, then go to Cad to set up coordinate system. Go to Toolspace,then Settings, then right click on the drawing

Export point coordinates from Autocad to Excel

Export point coordinates from Autocad to Excel::

This tutorial uses a programming language called Lisp to
be loaded in autocad.

First copy this code to a text file then save it as exportPoint.lsp,

Android Canal Design Software

First of all I want to apologize to those whom I've distributed my first android app during the training on Palawan, which is for designing of canals. It has a glitch on the part of computation for wetted area and wetted perimeter.
I missed to include the depth of water for the computation so there is an error although there are times that it

Design of Shear Reinforcement for Structural Members

DESIGN FOR SHEAR REINFORCEMENT

WSD

Procedure:

(Note: This procedure is a simplified version I summarized of the theoretical computation to be used for NIA structural designs. Please check with your conventional method.)

1. Compute for actual shear at a distance d from the support.

(d being the total height of the beam where the critical shear is)

Import Coordinates from Excel to Autocad

To those who doesn't know this stuff yet, this will be useful especially if you want to sketch your water surface gradeline by trial & error.

I found this useful because after our surveyor plotted the profile of a proposed canal, the hard copy could be lost someplace. So it is beneficial to have a soft copy on the computer.

Vertical Drop v2

I want to share this app I wrote about design of vertical drop structure.
This tool uses CB elevations of the canal inlet and outlet instead of water surface elevation to solve the cistern depth and height.

CanDe 1.0.0.1

I just want to share this tool I wrote as a console application. This is called CanDe, stands for canal design.

This features designing of concrete and unlined canal. It also includes a quantity estimate for volumes of
