**Title:** Automatic Structures - Recent Results and Open Questions

**Abstract:**

Regular languages are languages recognised by finite automata; automatic structures are a generalisation where one looks also at automatic relations which are relations recognised by synchronous finite automata and at automatic functions which are functions whose graph is an automatic relation. Functions and relations first-order definable from other automatic functions and relations are again automatic. Automatic functions coincide with the functions computed by position-faithful one-tape Turing machines in linear time. This talk gives an overview on recent results on automatic structures and provides some concurrent research questions.

Frank Stephan received his doctorate from the University of Karlsruhe (T.H.)

in the year 1990 in mathematics. He since then worked at the University

of Karlsruhe (T.H.) until 1995, then at the Univerisity of Heidelberg

until 2003, at the National ICT Australia located at the University

of New South Wales until 2004 and since then at the National University

of Singapore. His working areas are in mathematical logic and theoretical

computer science; in particular he works in algorithmic randomness,

automata theory, inductive inference and recursion theory.

**Professor Belal E. Baaquie, National University of Singapore, Singapore. **

**Title: **Quantum Mathematics and Financial Modeling

**Abstract:**

The mathematics of quantum mechanics is a natural and efficient formalism for modeling financial instruments. A brief review is made of the modeling of option theory using the Feynman path integral. The modeling of forward interest rates is carried out using the framework of a two dimensional quantum field theory and the Hamiltonian is used for determining the martingale condition. An empirical analysis shows that the quantum modeling of forward interest rates is well supported by market data.

** Title:** Development of Diamond Detectors for Radiotherapy; Material & Technology

**Abstract**:

Diamond is a wide band gap semiconductor with atomic number close to biological tissues and cells and therefore a potential candidate among Tissue Equivalent Materials (TEM). Synthetic diamond technology has been geared up using Chemical Vapour Deposition (CVD) route to produce poly crystal and single crystal diamond sheets. Whereas sc-Diamond is more useful as dosimeter, pc-Diamond has further applications as UV and high energy particle detector. With the advancement in CVD processes for synthetic diamond substrate, understanding of material properties and related technologies has taken up momentum. The polar surface of synthetic diamond due to CVD process is often Hydrogen terminated. The oxygen termination is therefore required to suppress leakage currents in sensor applications. These issues will be addressed in the talk while explaining technology development for diamond detector in Metal-Insulator-Metal (MIM) configuration. Some experimental results shall also be shared covering I-V at different temperatures.

Jamil Akhtar was born in Ghaziabad, India, in 1959. He received B.Sc (Hons) and M.Sc degrees in Physics with specialization in Electronics in 1977 and 1980 respectively. He joined BEL Ghaziabad as Planner B during 1979-80. From 1980 to 1983, he worked at CSIR-CEERI , Pilani, firstly as CSIR-JRF and then CSIR-SRF for his Ph.D. thesis work on “ Study of Two-Dimensional Breakdown Phenomena in Semiconductor Devices”.

Since 1983, he has
