To provide an example of circularly polarized absolute-value rays in a nondispersive absorbing medium, the theory of ray tracing is presented in the case in which a plane wave is incident on a planar layered medium. Specific tracing methods are presented for the loci of the real phase plane normal, the loci of the projection ray related to the flow line of the normalized Poynting flux, the loci of the circularly polarized absolute-value rays, and the intensities of these rays. The relationships to Poynting flux and their tracing method are described. Further, in the planar layered medium, an anisotropic projection ray index of refraction is introduced to the projection ray. It is shown that Fermat's principle holds under this index of refraction. On the other hand, Fermat's principle also holds in the tracing of the trajectory of the real-phase plane normal. In Fermat's principle of the projection ray, its relationship to the energy flux density is new.

Two methods were used to approximate site-specific biodegradation rates of monoaromatic hydrocarbons (benzene, toluene, ethylbenzene, and xylenes [BTEX]) dissolved in ground water. Both use data from monitoring wells and the hydrologic properties of the aquifer to estimate a biodegradation rate constant that can be used in ground water solute fate and transport models. The first method uses a biologically recalcitrant tracer in the ground water associated with the hydrocarbon plume to normalize changes in concentration of BTEX under anaerobic conditions;attenuation of the tracer is attributed to dilution, sorption, and/or volatilization. Attenuation of BTEX in excess of the attenuation of the tracer is attributed to biodegradation, although other processes may affect the observed rate. The second method assumes that the plume has evolved to a dynamic steady-state equilibrium. A one-dimensional analytical solution to the advection-dispersion equation is used to extract the rate of attenuation that would be necessary to produce a steady-state plume of the configuration found at the site. Attenuation is attributed largely to biodegradation because the analytical solution removes the effects of sorption and dispersion and volatilization is assumed to be minimal. Neither method fully accounts for the effects of continuing dissolution of BTEX in the source area or nonlinear sorption. Therefore, the rates cannot be attributed fully to biodegradation, but still are useful for ground water contaminant fate and transport modeling. The methods were applied to a data set from a JP-4 jet fuel spill at Hill Air Force Base, Utah. In estimates along two separate flow paths, natural attenuation rates for BTEX ranged from 0.006 to 0.038 day (-1), with most rates near 0.02 day(1). The rate for benzene ranged from 0.025 to 0.038 day (1). The rates of attenuation of individual BTEX compounds as estimated by the two methods were in close agreement. For an individual compound, the rate es

Fundamentals of Electromagnetic Waves(Shokodo Publ.) andFast Inversion of Laplace Transform by BASIC(Kyoritsu Publ.). He is coauthor ofModern Analysis of Electromagnetic Fields(I.E.I.C.E.).

In the analysis of a general linear system including the electromagnetic wave transmission systems, it is often necessary to derive system functions such as the immittance function and the transfer function from the frequency characteristics. In solving these problems, it is possible to use the Herglotz-Cauer theorem for the immittance function and Hosono's theorem for the transfer function. In these theorems, it is necessary to calculate integrals on the frequency when the system function is derived. There are a limited number of cases that can be solved analytically. However, when Hosono's theorem is combined with the fast inversion of Laplace transform (FILT), it is predicted that such a combination is a powerful tool for analyzing the transient phenomena of the electromagnetic wave propagating in plasma, wave-guides, and optical fibers. To confirm such a prediction, the transient phenomena of the electromagnetic wave propagating in a plasma were analyzed as an example so that the effectiveness was supported.

作者： Takaya, H Kambayashi, T Faculty of Engineering Nagaoka University of Technology Nagaoka Japan 940–21 Received his B.S. degree from Nagaoka University of Technology in 1993. In 1995 he entered the Master's program at the University. Received his B.S. degree from Yamanashi University in 1972 and his Ph.D. degree from Tokyo Institute of Technology in 1977.

In this paper, the aims of our study are to analyze the gain of semiconductor optical amplifiers with tensile strained multiple quantum wells and to examine the structure for polarization-insensitive characteristics for the purpose of showing the design guidelines. Since lasers with conventional lattice-matched multiple quantum wells have large optical confinement coefficient and large gain coefficient for TE mode, they are not polarization insensitive. Since the modal gain is the product of the optical confinement coefficient and the gain coefficient, the elimination of polarization sensitivity requires increasing the gain coefficient for the TM mode by applying the tensile strain to the well layer in order to compensate for the difference in the optical confinement factor. Assuming a multiple quantum well structure, the analysis obtains the strain distribution over the structure and an envelope function of the wave function and calculates the gain using a density matrix method by electron relaxation effect. It includes the band mixing effect of valence bands. As a result, a structure with little modal gain difference over a wide range at 1.55-mu m wavelength has been designed. Also, as a result of examining the effect of deviation from the designed values, it has been found that the variation in the material composition (amount of strain) has a larger effect on the modal gain difference than the variation in the quantum well thickness.

This paper proposes a linear-programming optimization-based method for reactive power scheduling using generator terminal voltages and reactive outputs, transformer tap-settings and switchable reactive power sources as control variables. dual linear programming is applied to minimize a composite objective function consisting of the cost of the adjusted control variables and the system transmission losses. The proposed composite objective function is more economical than that of the minimum total adjustment of the control variables and calls for less adjustments of var sources to meet the desired voltage limits. The proposed method is applicable to practical transmission and distribution networks, 500 kV to 11 kV of small and large sizes.

Aerobic biodegradation of vapor-phase petroleum hydrocarbons was evaluated in an intact soil core from the site of an aviation gasoline release. An unsaturated zone soil core was subjected to a flow of nitrogen gas, oxygen, water vapor and vapor-phase hydrocarbons in a configuration analogous to a biofilter or an in situ bioventing or sparging situation. The vertical profiles of vapor-phase hydrocarbon concentration in the soil core were determined by gas chromatography of vapor samples. Biodegradation reduced low influent hydrocarbon concentrations by 45 to 92 percent over a 0.6-m interval of an intact soil core. The estimated total hydrocarbon concentration was reduced by 75 percent from 26 to 7 parts per million. Steady-state concentrations were input to a simple analytical model balancing advection and first-order biodegradation of hydrocarbons. First-order rate constants for the major hydrocarbon compounds were used to calibrate the model to the concentration profiles. Rate constants for the seven individual hydrocarbon compounds varied by a factor of 4. Compounds with lower molecular weights, fewer methyl groups, and no quaternary carbons tended to have higher rate constants. the fist-order rate constants were consistent with kinetic parameters determined from both microcosm and tubing cluster studies at the field site.

Bulk-type domain reversal gratings of LiTaO3 crystal were fabricated at room temperature by the direct electric field method, The nonlinear optical. property of the crystal was evaluated by quasi-phase matching. The period of the bulk-type domain reversal gratings on an LiTaO3 substrate was 7.5 mu m and the domain reversal extended to the entire substrate thickness of 500 mu m. The experimental normalization efficiency was 0.46%/W . cm in carder quasi-phase matching and was close to the theoretical value (0.48%/W . cm). This result indicates that high-efficiency nonlinear interaction could be achieved by using the bulk-type domain reversal grating, The bulk-type domain reversal grating of nonlinear optical crystal such as LiTaO3 is expected to be useful for compact nonlinear optical devices and integrated laser sources.

The electromechanical coupling coefficient k can be determined by measuring the frequency characteristics of admittance. However, it is known that the specimen shape affects the measurement of the admittance frequency characteristics. In this paper, the finite element method was employed to investigate the effects of sample electrode inclination on the electromechanical coupling coefficients. The results indicate that the electromechanical coupling coefficients for the stretching vibration mode (31) of a rectangle, the stretching vibration mode (33) of a bar, and the expansion vibration mode (p) of a disk decrease when the sample electrodes are inclined. No spurious vibration was observed in the transverse vibration of (31) and (p) modes when the sample electrodes were inclined. However, a spurious vibration was observed in the longitudinal vibration of the (33) mode. These observations were confirmed by experiment.

A theory of natural observation methods was originally formulated for two complementary systems: neighboring type and equilibrium type. This paper introduces a new system, normal-type system, that is different from the forementioned two types. One characteristic feature of the normal-type natural observation method is its ability to reconstruct an original waveform from the sum of a finite number of observation values. The natural observation theory of a normal type evolves naturally under the condition that a waveform and its power component can be expressed in the sum form. These meanings are discussed by comparing a frequency response of the normal-type natural observation transform with that of a conventional filter bank. Furthermore, a criterion for determining observation parameters in order to realize the natural observation of normal type under a given tolerance of error is described. It is believed that the proposed theory offers new insights into systematization of the natural observation theory.

Theoretical studies on Iijima's ''Theory of Pattern Recognition,'' which is known as a method of multiple similarity, have shown clearly that there are situations when it is difficult to determine the viewpoint and visual field, important parameters to introduce topological aspects into the pattern space, observing a figure itself. To cope with this problem, this paper proposes transforming the observed image from a figure f(r) to a second-order differential image rho(r), called ''figure source.'' The aim is to reconstruct the theory in such a way as to enable the application of similarity evaluation methods as in the conventional case, without compromising the current theory, and all the necessary proofs are given. In this paper, the figure source equation as well as rules representing its properties are developed, and several related physical quantities are redefined.
