To make the vast digital archives of music more easily accessible, it is necessary to have searchable music descriptors, or metadata, that are meaningful and robust. While metadata conventionally covers editorial information that accompanies the music on a CD such as genre and artist, it could also include community-contributed labels such as mood. On the other hand, signal processing methods can be used to extract specific musical knowledge automatically from audio signals. In this tutorial we present signal modeling and analysis methods for speech and music motivated by audio classification and retrieval applications. The basic building blocks of a music retrieval system are the signal processing front-end that extracts perceptually relevant features from the signal, and the pattern matching module that serves to detect musically relevant similarities between signals. The audio processing research is even more challenging due the fact that signal characteristics as well as important musical attributes are culture-specific and therefore need specific data representations and models. We draw upon examples from Indian music to illustrate the design of feature extraction and similarity-based search methods for audio retrieval.

In the first part of the workshop, fundamentals of circuit simulation will be discussed. Techniques for assembly of circuit equations, solution of non-linear problems, and solution of ODEs will be discussed along with examples. Advantages and limitations of the various methods will be described. Following this introduction, several circuit simulation examples will be taken up, and simulation results will be illustrated.

The second part of the workshop is a hands-on session in which the participants will be given a few simulation problems. The hands-on session will be based on the public-domain simulation package, SEQUEL. However, the expertise gained by the participants in this session would be of a general nature, i.e., it will also help them in using other simulation packages.

Real-time simulation is concerned with the simulation of circuits and systems, such that the time taken to simulate a particular interval is the same as the actual time of that interval. An important application of real-time simulation is hardware-in-loop (HIL) testing of controller hardware and software. In this tutorial, we will be concerned with the overall environment for real-time simulation, followed by the hardware and system software requirements for setting up a real-time simulator. We shall present and review different architectures for real-time simulators, and present one architecture in detail. We shall also provide a background which could enable participants to assemble their own small-scale real-time simulation platforms for specific tasks.

Information Security Threats are affecting every computer and mobile device user. Not only large and sovereign organisations but SME/individual users are also exposed to large scale frauds, theft of information asset and information exposure. Some common techniques are - hacking, phishing, 419 scams, identity thefts, email account hijacking, blackmail, embarrassment, social engineering, credit card skimming and internet banking thefts, etc. This tutorial will expose the participants in user friendly and simple language about (a) introduction to various types of cyber crimes, (b) how are these done, (c) risks and effect on common users and organisations, (d) various dimensions of cyber crimes. (e) How to protect yourself and mitigation strategies.

With so many microcontrollers available, why choose the MSP430? Whether teaching in a lab or for use in a project, the MSP430 range is suitable for both. With a RISC based instruction set and a von-Neumann architecture, the MSP430 is easy to program. The choice of programming in C or assembler is up to you. Develop code faster with a choice of software platforms, and debugging utilities included. With up to 25MIPS of performance available, on-chip flash memory and a completely integrated signal-chain, the MSP430 offers a genuine single-chip solution for academia. In the first part of the workshop, Need for Low power Embedded system and various methods for low-power modes will be discussed. Advantages and limitations of the various methods will be described. Following this introduction to MSP430 Family Architecture and Integrated peripherals.

The second part of the workshop is a hands-on session in which the participants will be given hands on Training on MSP430 Development Tool and Code composer studio IDE; it will also help in development of Applications and Demonstrations of MSP430 Applications.
