Syntax and Semantic

I spent the last month assisting my advisors on writing an NSF research proposal. It was one of my most exhausting and educational experiences ever. It all happened slowly through some random tasks I got assigned. Some tasks seemed trivial and even useless at the time, but it all made sense when we worked on the complete proposal draft.  It started with writing a "brain dump" of all ideas we have been iterating over the past 4-6 months. Then, it got interesting. The Interesting Platform (Motivation, use cases, existing problems) The brain dumb is often too technical as I spent time going through related work and defining interesting problems, what people are working on, and where I stand in all of that. This all does not cut it unless there is a clear use case. A scenario where all proposed research ideas are employed to make something "cool" happen. The idea of how such use cases look like went through several phases: 1) When I started working on the proje...

DARPA Robotics Challenge Finals 2015 took place at Fairplex (Pomona, California). The event included an expo with tons of robotics shows and even some booths where you can play around with the robots. The competition took place on 4 tracks each with a replica of the challenge stage.  The tracks: The winners: Team KIAST making it look way too easy with Hubo Running man, a robot with an attitude and a large cheering squad, walking on rubble for the win.   Chimp leaving at its own terms .. like a true champion. Random moments: The expo and the demos:

Correction (4/24/2014): for your driver to work the AR Drone 2.0 you have to compile the kernel version provided by Parrot which can be found here https://devzone.parrot.com/projects/show/oss-ardrone2 One of the down sides of "out of the box" AR Drone 2.0 is that you can't control multiple drones from the same machine. Another down side is that you can't attach USB devices except flash memories and some other predefined devices due to the limited nature of the busybox deployed on the drone. To over come the first down side without manipulating the WiFi configurations of the built-in WiFi card (i.e. you don't want to mess up your new drone), you will need to overcome the second problem (i.e. install a WiFi dongle and its driver manually). In this tutorial, I try to walk you through the steps to do just that. I assume that you are working a Linux machine (seriously we are not going to compile drivers on Windows). Ubuntu is preferable ! Because the Drone has a...

TV ratings conventionally depend on focus groups and/or set top devices that keep track of the channels and shows viewed. This approach has been the main source of information for rating TV shows, sports, news, etc and it has been an integral part of the economics of the TV industry . But with the growing sources of viewing TV programmes either live (using TV sets or online streaming) or later (using video on demand either through set top devices or online portals) and with the growing number of TV viewers posting their opinions about what they are viewing, TV programmes rating is become a more challenging task that requires innovative solutions. On the other hand, recently booming terms like "Connected Viewers" and "Two Screen Viewing" describe TV viewers that use their smart phones or tablets while watching TV. These smart devices forms a rich source of information on the TV viewing habits of the device's owners. This information can help both the TV ind...

Recently, I have been working on integrating Click Modular Router to work with both WiFi cards and USRPs to facilitate the development of cognitive radio testbeds. I am using GNURadio to control N210 USRPs . I found that developing routing hops to be interesting and worth sharing as it requires the USRP to simultaneously send and receive. This requires the transmission and reception to be on separated frequencies.  For transmission, first a client socket must be created in the click configuration code. Socket(TCP, localhost, 4002, Client true) Then, I used a thread to constantly listens on that socket and transmits the data once a new packet is received. This allows for the separation of tasks and good visibility of the transmission code. I noticed that there is a trend to include the transmission code within the main function which degrades the code readability. The thread takes as a parameter the top_block describing the data path on the USRP. clas...

For the third year I was invited to give a talk at Software Freedom Day @ Alexandria University 2011 and I wanted to talk about something that links what I am doing now (I am a research assistant at E-JUST) and open source so I started researching Open Source Science. Starting from the fact that I use a lot of open source modules and packages in my work developed by others and put on the internet for everyone to use. I began to understand the wider concept of open science which aims at enabling everyone who is willing to participate in any scientific endeavor to have a part in it. Facilitated by the internet, ideas, tasks, documents, code, scientific data and even videos of experiments are shared by the project's coordinator for anyone to participate in anyway and every way possible. And the results are amazing !! My main goal from the presentation and this post is to show how openness can boost research either by using the collective intellige...

Today I presented "Contributing to Open Source" as a part of Software Freedom Day @ Alexandria University 2010 held at Bibliotheca Alexandrina. The audience was great and helped in making the presentation better than I anticipated. This is the presentation I hope it would be useful to those that missed the event.
