Projects handled

Qualcomm Projects (4)

7x30 Windows Mobile 7 - Qualcomm Technologies, San diego

Process starts from getting the PLFs (Perforce List File) from

various teams and integrating them onto main target PLF. Then the build

will be spun on remote servers and any errors will be reported to

appropriate team and the fixes will be picked up. Once the build is

ready, sanity tests (listed above) will be run on the H/W with this build

loaded and any bugs will be reported to appropriate teams. If needed CRs

will be raised in CRMDB for a team and will be kept track off till the

issue has been resolved. Finally, Strip process and Pack process will be

done over completed builds and will be released to the customer.

Mobile Applications memory usage analysis - Internship, Qualcomm

Technologies, San diego

Map files resulting in a mobile build have been parsed and the memory

usage of each individual component has been extracted already. Customizing

this application to provide a user friendly interface is being done.

diego

Features not needed by customers need to be removed from the mobile

applications. Customizing the software according to the customer's needs

has been done for various builds and validated in lab.

Building Mobile applications - Internship, Qualcomm Technologies, San diego

Applications that are to be embedded into mobile applications are

built on batch servers. The resulting build files are loaded onto mobile

and their performances were compared. Agglomerative and CURE algorithms for

hierarchical clustering, and DBSCAN and K-Means algorithms for partitional

clustering were implemented.

Comparative study of various data structures for shortest path algorithm -

Advanced Data Structures, UFL

Array, Fibonacci heap and Binomial heap are used to implement

Dijkstra's shortest path algorithm and their performances are compared by

varying the number of points. Random mode, in which random number of points

was used and the user mode in which a file having the points defined by the

user were used to compare performances. Implemented using C++.

P2P file sharing software - Computer Networks, UFL

A p2p file sharing software that acts both as a client and a server

was implemented. The client functionality download files from a running

server and the server functionality includes sending the list of files and

the requested file. Additional features that were implemented are

reassembling of the downloaded files and measuring latency. Implemented

using C++.

BitTorrent - Computer Networks, UFL

is used in controlling the switching between the power source and battery

power supply in case of power cuts. Sequences of 24 tests have to be

performed on each Flat Pack and the results have to be displayed to user.

Detector Pack Inspection System - GE, Milwaukee, US

Defects in packs such as spots, chip off, cracks, centering,

inclination, skew and focusing are inspected by keeping the pack in a

fixture. This project helps the user to ensure that the fixture is

perfectly aligned below the camera.
