a. Ph.D thesis on "Studies on Ionospheric Absorption of E- and      F- region echoes" Andhra University
b. Research since 1971 in the following areas:
     1. Ionosopheric Physics:

• Participated in setting up and maintenance of equipment and aerial systems for measuring vertical incidence pulse absorption called A1 technique on two frequencies 2.4 MHz and 5.6 MHz.
• The Sen Whyller and Appleton-Hartee formulations of the magneto-lonic theory was developed for computing F-region absorption. The extension of the magneto-ionic theories to vover the case of electron-ion collisions is a valuable contribution to the theory of F-layer absorption as the above theories were taken into account only binary collision i.e., electron-neutral collision only.
• A new and simple numerical method was developed for translating into computer language for computing absorption from full Appleton-Hartee and Sen-Whyller formulas.
• A theoretical electron density N(h) profile for the height range 50-300 km was proposed to describe the ionosphere over Waltair which gave absorption, group height values consistenct with expermentally measured values.
• Diurnal, Seasonal, frequency variation of absorption, magnetic activity and lunar tidal effects on absorption were studied. One of the significant observations of solar proton emission (charged particle) effects on absorption at low latitude inospheeric was reported first time.

2 Process Control Instrumentation:

• Design and erection of General purpose real - time Process Control Development System:. Project sanctioned by CSIR.
• Micro-controller based process control systems are tried out in India recently and they are to be imported. R&D in this area leads to a lot of savings in foreign exchange and self-sufficiency in this technology.
• The research project is aimed to design and develop a real-time process control development system and to make a proto-type cost effective micro-controller for real-time process control applications. It is also aimed for mass production and import substitution.
• For the development of proto-type Microcontroller and Intel IPDS 100 personal development system and single board emulator ISBE'96 (MCS 96) along with the state of the art Microcontrollers 8397, 8797 chips were imported.

3.R & D of Instruments:

• Designed and fabricated accessories and gadgets required for analytical instruments. Modified the design of some obsolete units for keeping them in working condition. Designed and developed special power supplies, digital trainer systems, A/D converter systems, Interfaces for 8085 Microprocessors, Temperature indicators, logic tester, Instrumentation amplifiers, Digital voltmeter, stabilizers and transducers.

Research Work Directed:

Sri D.B. Venkatadri, Lecturer, USIC is working for PhD on the "Thermal Behaviour, Iuminescence Characters of some organic compounds and conducting polymers", which are useful for T.V. Screens and other applications.
