called "effet Doppler-Fizeau"). It is often overlooked that in Doppler’s publications (and also Einstein’s in his discussion of the Doppler effect) he explicitly acknowledges that his formulae are only approximate since he made several mathematical approximations in his derivation. Doppler’s derivation is repeated more or less verbatim in most modern textbooks but often

CHAPTER 16 MANAGING BOND PORTFOLIOS 16-1 Outline of the Chapter • Bond pricing and sensitivity of bond pricing to interest rate changes • Duration analysis – What is duration? – What determines duration? • Convexity • Passive bond management – Immunization • Active bond management 16-2 Interest Rate Risk • There is an inverse relationship between interest rates (yields) and price of the bonds. • The changes in interest rates cause capital gains or losses. • This makes fixed-income investments

Continuously variable slope delta Modulator INTRODUCTION:- Continuously variable slope delta modulation (CVSD or CVSDM) is a voice coding method. It is a delta modulation with variable step size (i.e. special case of adaptive delta modulation)‚ first proposed by Greefkes and Riemens in 1970. CVSD encodes at 1 bit per sample‚ so that audio sampled at 16kHz is encoded at 16kbit/s. The encoder maintains a reference

#1 True or false: Even if the sample size is more than 1000‚ we cannot always use the normal approximation to binomial. Solution: If a sample is n>30‚ we can say that sample size is sufficiently large to assume normal approximation to binomial curve. Hence the statement is false. #2 A salesperson goes door-to-door in a residential area to demonstrate the use of a new Household appliance to potential customers. She has found from her years of experience that after demonstration‚ the

(adapted from L.A. Zadeh) Lecture 1 What is soft computing Techniques used in soft computing • Soft computing differs from conventional (hard) computing in that‚ unlike hard computing‚ it is tolerant of imprecision‚ uncertainty‚ partial truth‚ and approximation. In effect‚ the role model for soft computing is the human mind. 1 2 What is Hard Computing? • Hard computing‚ i.e.‚ conventional computing‚ requires a precisely stated analytical model and often a lot of computation time. • Many analytical

MATHEMATICAL MODELLING OF MICROWAVE HEATING OF FOOD By M . SHIVA KUMAR ( 04AG1008 ) Under the guidance of PROF. SURESH PRASAD ABSTRACT • The use of microwaves in the food industry is attributed to the lower time needed to increase the temperature of foodstuffs compared to the traditional heating methods. •However‚ the heating is not uniform and the products show hot and cold spots. • In order to analyze the behaviour of foods heated by microwave oven‚ a mathematical method was developed

Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases
