Authors: Keel Pamela K. , Mitchell James E. , Davis Traci L. , Crow Scott J. 
Published: August 2002

AbstractObjectiveBoth cognitive‐behavioral therapy (CBT) and antidepressant medication have demonstrated efficacy in the treatment of bulimia nervosa. However, data concerning the long‐term impact of such treatments have been limited. This study sought to determine if treatment with CBT and antidepressant medication was associated with better long‐term outcome among women diagnosed with bulimia nervosa.MethodWomen (N = 101) who completed a controlled treatment study of bulimia nervosa participated in follow‐up assessments approximately 10 years later.ResultsWomen who received treatment with CBT or antidepressant medication or both reported improved social adjustment at long‐term follow‐up compared with women randomized to the placebo condition.DiscussionTreatments with demonstrated efficacy for short‐term outcome appear to improve psychosocial function at long‐term follow‐up among women initially diagnosed with bulimia nervosa. © 2002 by Wiley Periodicals, Inc.

Research on energy expenditure in individuals with eating disorders: A review
Authors: Zwaan Martina de , Aslam Zaheer , Mitchell James E. 
Published: August 2002

AbstractObjectiveThis study reviews the published research on energy expenditure in individuals with anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED).MethodIndividual studies are reviewed and their results summarized.ResultsThe most consistent finding is evidence of reduction in resting energy expenditure (REE) in patients with AN, which increases with increased energy intake and body weight. Data regarding BN are inconsistent. Three available studies in subjects with BED have not found evidence of changes in energy expenditure corrected for lean body mass compared with obese non‐binge eaters.DiscussionThe ability to reliably and cost‐effectively measure REE may aid in the refeeding of patients with AN where REE is reduced. Changes in BN and BED subjects have yet to be identified consistently. © 2002 by Wiley Periodicals, Inc. Int J Eat Disord 31: 361–369, 2002.

Published: August 2002

AbstractObjectiveThe Internet serves as a potentially effective method of treatment delivery through widespread education and interaction via synchronous Internet relay chat (IRC). The current study explores the feasibility of IRC in the delivery of an eating disorders prevention intervention.MethodThis small pilot study describes the delivery of an efficacious eating disorder treatment using a novel medium. The on‐line sessions are based on cognitive‐behavioral treatment and are facilitated by a moderator. In addition to feasibility, preliminary evidence of acceptability and efficacy for an on‐line intervention with college‐aged women is reported.ResultsResults indicate that IRC is an acceptable and feasible format for treatment delivery. In addition, descriptive and qualitative data suggest that this method of treatment delivery is potentially effective.DiscussionThis pilot study provides increased knowledge of the viability of treatment delivery over the Internet, specifically, a psychoeducational IRC for eating disorder prevention. © 2001 by John Wiley & Sons, Inc.

The role of family of origin food‐related experiences in bulimic symptomatology
Authors: MacBrayer Elizabeth K. , Smith Gregory T. , McCarthy Denis M. , Demos Stacy , Simmons Jean 
Published: August 2002

AbstractObjectiveWith the goal of developing a model relating family of origin experiences to maladaptive cognitions to bulimic symptom formation, the authors developed a measure of family of origin food‐related experiences called the Family History Inventory.MethodA number (N = 662) of sixth to eighth‐grade adolescents completed the inventory, eating and dieting expectancy measures, and the Bulimia Test‐Revised (BULIT‐R).ResultsFourteen scales were identified in the inventory. They emphasized family teasing about weight, negative maternal modeling regarding food, and family rules concerning eating. Eleven of the 14 scales correlated with the BULIT‐R. Two superordinate factors called Family Teasing and Negative Maternal Modeling summarized 8 of the 14 subscales. Statistical tests were consistent with the hypothesis that eating and dieting expectancies mediate the influence of Family Teasing and Negative Maternal Modeling on bulimic symptomatology.DiscussionThere was good evidence for the validity of the Family History Inventory. The theoretical implications of the mediation tests are discussed. © 2001 by John Wiley & Sons, Inc. Int J Eat Disord 30: 149–160, 2001

Published: August 2002

AbstractObjectiveWe report on a 13‐year‐old girl with coincidental occult intracranial tumor and early‐onset anorexia nervosa.MethodThe cerebral meningioma was discovered fortuitously as the result of a research project using SPECT imaging to locate a neurobiological substrate in patients with anorexia nervosa. Without SPECT, the meningioma would have remained undiagnosed until it had become symptomatic. The two conditions appear to have been completely unrelated.Results and DiscussionThe case highlights two important points. First, intracranial pathology should also be considered however certain is the diagnosis of early‐onset anorexia nervosa. Second, neuroimaging plays an important part in diagnosing early‐onset anorexia nervosa, both from a clinical and a research prospective. © 2001 by John Wiley & Sons, Inc.

Published: August 2002

AbstractIn this paper, we employed a stratospheric aircraft system in mobile communications and conducted field tests on the visibility and shadowing states based on measurements to construct a simulation of a varying communications environment. Based on these measurement data, we present the basic transmission characteristics in a mobile communication environment using stratospheric aircraft, and propose and evaluate the performances of the Time Division data transmission Among Aircraft (TDAA) scheme, which has the objective of lessening data losses due to shadowing as a specific communication scheme, and the Directional Access using Shadowing (DAS) scheme that is used in a shadowing environment in the uplink line. We also evaluate the performances of the Aircraft Position Control (APC) scheme and the Pilot Signal Control (PSC) scheme, which are flow control schemes having the objective of load distribution in high‐load regions. © 2001 Scripta Technica, Electron Comm Jpn Pt 1, 85(1): 22–34, 2002
Scattering of plane wave by a 3D smooth convex impedance surface using physical theory of diffraction with transition currents
Authors: Kobayashi Hirokazu , Hongo Kohei , Moriyama Toshifumi 
Published: August 2002

AbstractThis paper discusses a method of calculation that uses physical optics with transition currents for the scattering field produced when a plane wave illuminates a 3D smooth convex impedance surface. The high‐frequency technique is necessary for evaluating RCS of large objects with respect to wavelength, such as automobiles, and physical optics is a powerful approximation method. However, the evaluation of electromagnetic current is based on geometric optics and there has been a need to improve accuracy in diffraction areas in directions other than mirror reflection. The method proposed in this paper estimates electromagnetic current in a transition region from canonical problems. It is seen that calculation accuracy is greatly improved by considering the transition currents in a small area. This paper evaluates the transition current by using the Fock‐type current as the canonical problem for a smooth convex impedance surface and recognizes the effectiveness of this method of calculation through numerical calculation of these 2D or 3D convex objects. © 2001 Scripta Technica, Electron Comm Jpn Pt 1, 85(2): 30–40, 2002

Authors: Nobesawa Masaru , Tamaki Kosei , Hasebe Nozomu , Yokoyama Itsuro 
Published: August 2002

AbstractWith a view to estimating the induced voltage generated in a communication cable by incoming radio waves, this paper carries out an analysis specifically for the common mode and compares the results with the measured values. In the theoretical analysis, communication cables installed in an urban area are considered. An analysis model is introduced in which both ends of the cable are sloped down to the ground surface. In the analysis, the communication cable is treated as the sum of infinitesimal dipoles. From a comparison of the theoretical and measured results, the usefulness of the proposed analysis method is discussed. First, an experiment on a conducting ground plane with a scale model is carried out. Satisfactory agreement with the theoretical values is demonstrated. Next, a field experiment is carried out by using a practical 10‐pair communication cable and terminating sets. As a result, it is found that an evaluation of the induced voltage generated in the cable is possible by paying attention to the settings of various parameters used in the analysis, although quantitative agreement is not reached. © 2001 Scripta Technica, Electron Comm Jpn Pt 1, 85(4): 10–22, 2002
Safety inquiry system based on mobile agent communication
Authors: Isogai Mitsuo , Kumai Mitsuyuki , Kobayashi Youichi , Kuroiwa Katsutoshi , Arakawa Yoshiki , Suzuki Ryutaro 
Published: August 2002

AbstractWe constructed an information retrieval system using mobile agent technology and evaluated it for safety inquiry at disasters. The reason we used mobile agents is robustness against disasters and decrease of communication load. Failure, shutdown, and recovery of communication lines may occur in a large scale and high frequency at disasters, but the agent software autonomously detours or waits and brings back retrieval results. Retrieval is done from outside to inside of the stricken area. We conducted experiments using the agent method, Client/Server (C/S) method, and a combination of the two, and evaluated the results based on traffic amount and response time. We verified that information retrieval by mobile agents has robustness against disasters, and becomes more effective in order to decrease traffic on terminal lines compared with C/S method, as the number of retrievals and the number of migrated servers get larger. © 2002 Scripta Technica, Electron Comm Jpn Pt 1, 85(6): 53–63, 2002
Time‐Domain Analysis of One‐Dimensional Quantum‐Mechanical Waves Using Bergeron Equivalent Circuits
Authors: Sanada Hirofumi , Suzuki Masakiyo , Nagai Nobuo 
Published: August 2002

AbstractElectron wave devices making use of the wave nature of the electron have been studied extensively. It is important to systematically understand and use the wave phenomena in a potential structure as the operating principle of these devices. In this paper, a method based on Bergeron equivalent circuits is proposed as a technique for time domain analysis of the electron wave propagation expressed by the one‐dimensional quantum‐mechanical wave equation. It is shown that by this technique the time domain analysis of the wave behavior described by the Schrödinger equation under the effective mass approximation and the two‐ and three‐band model equations can be systematically treated by nodal analysis, including boundary conditions. Also, as a boundary condition of an open system that is important in time domain analysis, an absorbing boundary condition due to a potential structure with loss is proposed. By means of the proposed technique, the time domain analysis of the incident wave packet on a GaAs/AlAs structure considering Γ − X mixing, and on a resonant interband tunneling structure is carried out and its behavior is described. © 2001 Scripta Technica, Electron Comm Jpn Pt 2, 85(1): 1–12, 2002.
On a reduced branch‐line coupler with two‐step stubs considering a spurious notch
Authors: Zhang Shaozhou , Tokuno Akihiro , Sakagami Iwata , Nagai Nobuo 
Published: August 2002

AbstractIn a reduced branch‐line coupler that is designed with two‐step stubs such that the area occupancy on the substrate is 25% of the standard branch‐line coupler, a sudden variation (spurious notch) occurs at a certain frequency in the frequency range higher than the center frequency. In this paper, the mechanism of generation of the spurious notch is investigated by using the eigenmode impedance obtained by mode decomposition. A circuit design that does not generate a spurious notch while maintaining the area ratio of 25% is developed. Next, by means of an experimental circuit, the effectiveness of the method is verified. © 2002 Scripta Technica, Electron Comm Jpn Pt 2, 85(2): 27–35, 2002
Yagi‐type hardware neuron model with CMOS IC
Authors: Sekine Yoshifumi , Torita Kiyoko , Matsuoka Jun 
Published: August 2002

AbstractWith a view to engineering applications of the information processing mechanisms used by neural networks in biological bodies, various studies have been conducted on pulse‐type neurons and neural networks. When research on a large‐scale pulse‐type neural network is carried out, there are limitations on computer simulation, so that hardware realization is desirable. When a neural network is realized by hardware, it is advantageous to model a single neuron by a CMOS IC suitable for large‐scale LSI. In this paper, in reference to the Yagi neuron model, a pulse‐type hardware neuron model, it is shown that a new pulse‐type hardware neuron model can be constructed with a simple circuit configuration that can be realized with CMOS ICs. First, the equivalent inductor constructed with a low capacitance and an enhancement‐mode MOSFET is discussed. Its configuration and characteristics are elucidated. Next, the negative resistance circuit is discussed. A circuit is proposed that can be applied to the CMOS process. From their characteristics, it is shown that two new neuron models based on the Yagi neuron model can be constructed. They are the conventional pulse‐type neuron model fired by an external input and the pacemaker neuron model that can fire itself. © 2002 Scripta Technica, Electron Comm Jpn Pt 2, 85(3): 23–29, 2002
Measurement and modeling of MOSFET's 1/f noise with BSIM3 version 3.2 for an analog circuit design
Authors: Shimasue Masanori , Aoki Hitoshi 
Published: August 2002

AbstractIt has traditionally been known that one of the major noise factors which become an issue in analog circuits in audio frequency band and oscillator circuits in various frequency bands is the 1/f noise from semiconductor devices constituting the circuits. While the measurement and modeling of 1/f noise from semiconductor devices is very important for the design of these analog circuits, the difficulty in its measurement and characterization has been a problem. Also, with the recent progress of noise reduction techniques in MOS transistors, circuit configuration with MOS transistors has become possible in the analog circuits mentioned above. Therefore, in this paper the stable and accurate measurement of 1/f noise in MOS transistors and its modeling technique using BSIM3 Version 3.2, which is the most recent SPICE model for MOS transistors, are described. © 2002 Wiley Periodicals, Inc.

Symmetry between linear predictive coding and composite sinusoidal modeling
Authors: Sagayama Shigeki , Itakura Fumitada 
Published: August 2002

AbstractAn elegant relationship (here called symmetry) between the linear predictive coding (LPC) analysis and the composite sinusoidal modeling (CSM) analysis is described. The objective is to provide a systematic view of the theory of voice spectral modeling such as LPC, PARCOR, CSM, and line spectral pairs (LSP). All of these methods of analysis are reduced to the problems of deriving the model parameters for lower‐order autocorrelation functions equal to the number of degrees of freedom of the model. From the point of view of the theory of orthogonal polynomials, LPC and CSM are the theory of orthogonal polynomials of a unit circle (in the case of LPC) and on the real axis (in the case of CSM). Beautiful symmetries hold in regard to the formulation, definition of various parameters, and solution algorithm. Also, a new interpretation is given here for the LSP from the point of view of orthogonal polynomials. © 2002 Scripta Technica, Electron Comm Jpn Pt 3, 85(6): 42–54, 2002
High‐speed computation of 3D tensor product expansion by the power method
Authors: Murakami Jun , Yamamoto Naoki , Tadokoro Yoshiaki 
Published: August 2002

AbstractAs a method to expand the 3D array by the 3D tensor products, the 3D outer product expansion is proposed and is used in the compression of image data and the design of 3D digital filters. The computational procedure is to apply nonlinear optimization iteratively to derive the expansion coefficients and the expansion vectors. Generally, the problems in nonlinear optimization have been that the process may not converge or a solution other than the optimal may be derived, depending on the given initial value, or the computational complexity and the computation time become tremendous when the size of the 3D array is enlarged. In order to handle these problems, the authors devised a method of calculating the 3D outer product expansion without applying nonlinear optimization, by using the power method, which is known as a numerical eigenvalue computation method. The validity of the method is verified against the calculation results. The computation time can be decreased by applying the proposed method. The calculation also reveals that the orthogonality among the expansion terms is lost in the calculation of the outer product expansion. Consequently, an expansion based on the mathematical definition of the 3D tensor product expansion that satisfies orthogonality is considered, and it is verified that the calculation can be performed in this expansion by 3D outer product expansion by the power method. © 2002 Wiley Periodicals, Inc.

Data‐dependent median filtering with multiple windows for restoration of images corrupted by high‐probability impulsive noise
Authors: Ishii Hiroaki , Taguchi Akira , Okano Mitsuhiro , Sone Mototaka 
Published: August 2002

AbstractThe authors propose a new method for restoring images corrupted by high‐probability impulsive noise at 10 to 50%. The strength (number of instances) of impulsive noise present in the area adjacent to a processing point is not uniform even in images that are corrupted by high‐probability impulsive noise. In addition, when a processing point itself does not represent high‐probability impulsive noise, outputting the input signal as is without performing median filter processing is vital to avoid image degradation. Given the above, one approach for restoring images degraded by high‐probability impulsive noise is to first determine whether or not a processing point represents impulsive noise, and then perform median filter processing only when it is determined that impulsive noise is present. Second, when performing median filter processing, the amount of impulsive noise adjacent to a processing point must be estimated, the size of the filter window appropriate to that amount must be set, and efforts to preserve the signal must be made. In the proposed method the authors were able to unify three types of fuzzy inference. In addition, the proposed method is superior at handling images degraded by impulsive noise over a probability range of 10 to 50% when the fuzzy sets are fixed by setting the fuzzy sets in the three fuzzy inferences appropriately. © 2002 Wiley Periodicals, Inc.

A robust decentralized approach to the multiarea frequency control of power systems
Authors: Miyazaki Mariko , Liu Kang‐Zhi , Saito Osami 
Published: August 2002

AbstractIt is an important problem in multiarea power systems to attenuate the frequency deviation due to load change. Since power systems are spatially dispersive, decentralized control is more practical than lumped control. In this paper, we propose two robust decentralized control schemes for this problem. The difficulty with this problem is that the linearized model of a multiarea power system with frequency deviations as outputs is a MIMO system that has a transmission zero at s = 0. They key idea is to change the output of one subsystem so that the resulting new plant does not have any zero at s = 0. The new outputs are chosen carefully so that the regulation of the new outputs can guarantee the regulation of all frequency deviations and tieline power. Further, parameter uncertainty is taken into account in the controller design to achieve robustness. Simulation shows that the proposed methods are effective. © 2002 Wiley Periodicals, Inc.

An improved power flow for an ill‐conditioned power system with FACTS devices
Authors: Yorino Naoto , Takeuchi Tohru , Sasaki Hiroshi , Sugihara Hiroaki 
Published: August 2002

AbstractThis paper addresses the issue of the computation techniques for assessing the steady‐state power flows controlled by Flexible AC Transmission Systems (FACTS), which contain variable series compensators (VSC), phase shifters (PS), interphase power controllers (IPC), and unified power flow controllers (UPFC). An improved Newton–Raphson load flow program has been developed based on an analysis of the convergence characteristic of the conventional method. It is shown that the conventional method tends to suffer from ill‐conditioning problem, resulting in shrinkage of the convergence region. Based on examinations of the condition number of the Jacobian, a penalty function method is adopted in order to avoid the ill‐conditioning problem and to guarantee a successful convergence. Although the computational burden is increased about 2 to 3 times, the proposed method considerably extends the region of convergence. The effectiveness of the proposed method is demonstrated through numerical examinations using IEEE 57 and 118 bus systems. © 2002 Wiley Periodicals, Inc.
