Build systems are crucial for software system development. However, there is a lack of tool support to help with their high maintenance overhead. GNU Autotools are widely used in the open-source community, but users face various challenges from its hard to comprehend nature and staging of multiple code -generation steps, often leading to low quality and error-prone build code. In this paper, we...

Compiler support for intervals as intrinsic data types is essential for promoting the development and wide-spread use of interval software. It also plays an important role in encouraging the development of hardware support for interval arithmetic. This paper describes modi cations made to the GNU Fortran Compiler to provide support for interval arithmetic. These modi cations are based on a rece...

The IEEE wireless standard 802.15.4 gets widespread attention because of its adoption in sensor networks, home automation, and other networked systems. The goal of the project is to implement an enand decoding block for the IEEE 802.15.4 protocol in GNU Radio, an open source solution for software defined radios. This report will give an insight into the working of GNU Radio and some of its hard...

Go, a board game which originated from China, is now very popular in east Asia and gaining its popularity throughout the rest of the world. Due to its large board size (19×19) and complex life-and-death analysis, computer Go is still one of the toughest artificial intelligence problems faced by computer scientists. Even though it has been studied for more than 20 years, computer Go programs sti...

This paper gives a brief but comprehensive review of the Multitaper spectrum estimation method that uses the data tapers or windows in digital signal processing. Instead of using a single kind of window functions, here a cluster of window functions are mentioned, which is known as Slepian tapers. This taper family minimize leakage also, and computing them requires solving eigenvalue problems th...

More and more 64-bit systems are showing up on the market—and developers are porting their applications to these systems. Most code runs directly without problems—but there is a number of sometimes quite subtile problems that developers have to be aware of for portable programming and porting. This paper illustrates some problems on porting an application to 64-bit and also shows how use a 64-b...

We present a Software Defined Radio (SDR) based IEEE 802.15.4 transceiver testbed for GNU Radio. Our testbed is Open Source and fully interoperable with off-the-shelf TelosB sensor motes and the Contiki sensor mote operating system, from the physical layer to the network stack. The testbed can be setup and configured easily via a graphical user interface and applications can interface with the ...
