#### The deviation, density, and depth of partially ordered sets

(1989)

Let P be a poset, and let ? be a linear order type with |?| ? 3. The ?-deviation of P, denoted by ?-dev P, is defined inductively as follows: (1) ?-dev P=0, if P contains no chain of order type ?; (2) ?-dev P = ?, if ?-dev ...

#### Global extrapolation on three and four grids for special initial value problems

(1989)

Three- and four-grid extrapolation procedures are considered for special initial value problems of arbitrary order q > 1. � 1989.

#### Harmonic and intermodulation performance of active integrated-optic waveguides

(Kluwer Academic Publishers-Plenum Publishers, 1989)

An empirical formula is developed for the static input/output optical characteristic of the active integrated-optic waveguide. Using this formula, closed-form analytical expressions, in terms of the ordinary Bessel functions, ...

#### Harmonic and intermodulation distortion in condenser microphones

(1988)

A simple formula is presented for the input-output characteristic of the condenser microphone. Also, a closed-form expression is derived for the output voltage of a condenser microphone excited by a multitone acoustic input ...

#### Optimum design of nonlinear space trusses

(1988)

The structural optimization algorithms developed in recent years mainly consider the elastic behaviour of structures. The reserve of resisting loads in nonlinear regions is totally ignored. The optimum design algorithm ...

#### Non-resonance for linear differential systems

(1989)

The existence of a set of real numbers ?, depending only on ?0, is established such that if ? ?? 0, the system Y� = (i? + R)Y can be transformed into a system Z� = (i? + S)Z of the Levinson form. Here ?0 and ? are real ...

#### Modelling the current�voltage characteristic of a fluorescent lamp for computer-aided design

(1989)

An empirical formula is presented for the voltage-current characteristics of a fluorescent lamp. The three parameters of the formula can easily be obtained from the measured characteristics of the fluorescent lamp without ...

#### Methods with O(H4) and O(H6) Phase-Lags for Periodic Initial Value Problems

(1988)

Two families of computational methods are discussed for the solution of second order periodic initial value problems. The first is a family with O(H4) phase-lag, the periodicity equation coinciding with the periodicity ...

#### Calculation of the transmittance factor of Bahrain using solar radiation data

(Kluwer Academic Publishers, 1989)

The average atmospheric transmission factor was calculated for Bahrain by using two methods. One of them is derived from using actual (measured) global radiation results i.e. Sambo's model and the other derived from using ...

#### On intramolecular dyotropy: Structural effects on reaction rates and x-ray crystal structure - molecular mechanics correlations

(1989)

Differential kinetic behaviour in thermal dyotropic rearrangement of compounds containing a cyclohexa-1,3-diene ring as 2H donor held proximate to a variously-substituted norbornene element as acceptor is discussed in terms ...
