Numerical procedure with analytic derivative for unsteady fluid–structure interaction
Authors: Mbaye I. , Murea C. M. 
Published: July 2007

AbstractThe unsteady interaction between an incompressible fluid and a deformable elastic structure is analyzed. An implicit numerical method is proposed. At each time step, the stresses at the fluid–structure interface are determined as a solution of an optimization problem. The modal decomposition of the structure equations leads to a problem to be solved with a reduced number of unknowns. The analytic gradient of the cost function was derived. Numerical tests validate the analytic derivative and show the behavior of a two‐dimensional Navier–Stokes equations with plate‐like model interaction. Copyright © 2007 John Wiley & Sons, Ltd.
Towards workflow simulation in service‐oriented architecture: an event‐based approach
Authors: Zheng Yanchong , Fan Yushun , Tan Wei 
Published: July 2007

AbstractThe emergence of service‐oriented architecture (SOA) has brought about a loosely coupled computing environment that enables flexible integration and reuse of heterogeneous systems. On building a SOA for application systems, more and more research has been focused on service composition, in which workflow and simulation techniques have shown great potential. Simulation of services' interaction is important since the services ecosystem is dynamic and in continuous evolution. However, there is a lack in the research of services' simulation, especially models, methods and systems to support the simulation of interaction behavior of composite services. In this paper, an enhanced workflow simulation method with the support of interactive events mechanism is proposed to fulfill this requirement. At build time, we introduce an event
sub‐model in the workflow meta‐model, and our simulation engine supports the event‐based interaction pattern at run time. With an example simulated in the prototype system developed according to our method, the advantages of our method in model verification and QoS evaluation for service compositions are also highlighted.

The age at diagnosis of type 1 diabetes continues to decrease in Belgian boys but not in girls: a 15‐year survey

AbstractBackgroundThe age at clinical onset of type 1 diabetes is decreasing. Preliminary Belgian data suggested that this anticipation occurred preferentially in boys. We investigated whether this gender‐specific anticipation could be confirmed over a 15‐year observation period.MethodsIn Antwerp, we studied incidence trends between 1989 and 2003 in 746 type 1 diabetic patients under age 40. For 2928 antibody‐positive patients diagnosed nationwide during the same period, age at diagnosis was analysed according to gender and calendar year.ResultsIn Antwerp, the incidence of type 1 diabetes under age 15 increased significantly with time from 10.9/100 000/year in 1989–1993 to 15.8/100 000/year in 1999–2003 (p = 0.008). The rising incidence in children was largely restricted to boys under age 10 where the incidence more than doubled during the 15‐year period (6.8/100 000/year in 1989–1993 vs 17.2/100 000/year in 1999–2003; p < 0.001). Such an increase was not found in girls under age 10 (p = 0.54). This selective trend toward younger age at diagnosis in boys was confirmed in the larger group of Belgian patients where the median age at diagnosis decreased in boys—but not in girls—from 20 years in 1989–1993 to 15 years in 1999–2003 (p < 0.001).ConclusionsOver a 15‐year observation period, a selective anticipation of clinical onset of type 1 diabetes was found in boys but not in girls. This suggests that an environmental factor may preferentially accelerate the sub‐clinical disease process in young boys. Copyright © 2007 John Wiley & Sons, Ltd.
Parasitic reactances and invariant properties in nonlinear networks
Authors: Suzuki Yoshihiko , Maekawa Hidehiro 
Published: July 2007

AbstractThe effect of parasitic reactances on the original networks as a stage in the qualitative analysis of nonlinear networks is considered. The parasitic reactances considered here are in the form of capacitors connected in parallel with resistors in the branches of a tree and inductors connected in series with the resistors in the branches of a cotree. The first result seen is the effect of the parasitic reactances on the stability of the equilibrium point. It is shown that if the equilibrium point of the original network is strongly stable and matrix (M + Mt) is positive definite, the equilibrium point is asymptotically stable even with parasitic reactances. The second result shows the effect of the parasitic reactances on the eigenvalues of the linearized equation in the vicinity of the equilibrium point. The result shows that the eigenvalues can be classified into those which converge to the eigenvalues of the original network and those which diverge to infinity of the eigenvalues of the matrix ‐M, (λ = lim [a → ∞ sgn {λ(‐M]}), when the parasitic reactances approach zero uniformly (a → ∞).
Periodically sampled queues with multiserver and finite waiting room
Authors: Yoshida Makoto 
Published: July 2007

AbstractThis paper evaluates the effect of periodic data transfer from an input processor to internal processors in a distributed‐control, real‐time system. Two models comprising N (≧ 1) call processors (CP) and M (≧ 0) common buffers (CPB) are analyzed and compared. In one model data transfer from the input processor is accepted at any sampling point by the CP subsystem. In the other model data transfer is not allowed if one or more calls are being processed in the CP subsystem at the time of sampling. Steady‐state distributions of calls in the system immediately after the sampling points and maximum traffic to be carried (a0) for the above two models are derived under such conditions as constant sampling period (T), Poisson arrival and negative exponential processing time distribution (mean value h). Furthermore, using such distribution, the distributions of calls in the system at any arbitrary instant are obtained to formulate various performance measures such as the average number of waiting calls in and out of the system and the average waiting time (w). Finally, the following results are shown from some examples of numerical calculation. When T/h is small, although the system with call rejection gives lower performance in terms of a0 and w, it exhibits remarkable behavior in reducing the frequency of data transfer. As T/h which is determined by the sampling period.
Design of quadrature modulator for digital FM signaling with digital signal processing
Authors: Suzuki Hiroshi , Yamao Yasushi 
Published: July 2007

AbstractTo introduce digital transmission into mobile communications, various digital FM methods with a modulation index of 0.5, such as TFM and GMSK, have been studied. Stable operation of these transmission systems requires high accuracy in setting the modulation index and carrier frequency in the modulator. This paper describes a quadrature modulator that provides accurate phase control using digital signal processing (DSP). GMSK is used as a modulation scheme, and its characteristics are discussed in detail. In general, the output of a modulator adapting DSP contains deviations from the ideal analog waveforms attributable to sampling, quantization and truncation errors. These errors are superposed as noise on the modulating waves and cause degradation in signal transmission. The relation between the noise spectra and the circuit parameters is first analyzed and the design procedure is then made clear in a form of a flowchart. An example of circuit parameters yielding a ratio of the signal‐to‐noise spectra of 60 dB is given. We fabricated a DPS orthogonal modulator using these parameters and confirmed that the desired modulation characteristics could be obtained.
Error rate performance of a 4‐phase DPSK system with multiple co‐channel interferences in land mobile radios
Authors: Rang Wu Ke , Morinaga Norihiko , Namekawa Toshihiko 
Published: July 2007

AbstractIn land mobile communications in a small zone, the same frequency is used repeatedly for efficient use of the frequency spectrum. Therefore, co‐channel interference is easily generated. An analysis is made of the statistical characteristics and error rate performance of a fading 4‐phase DPSK system when multiple channel interference with an arbitrary modulation phase number is present. It is assumed that several services in addition to voice communication will be added in the future. The probability density of two orthogonal outputs from the differential detectors is derived using the characteristic functions, and, based on this quantity, the effects of multiple co‐channel interference on the error rate are studied analytically. The resulting theoretical equation contains not only the autocorrelation of the desired wave but also the correlation of each interference wave. This makes it possible to evaluate the multiple co‐channel interference, the power distributions of each interference and the number of channels. It is assumed that the fading spectra of the desired and interference waves are symmetric with respect to the center frequency.
On decoding methods for double‐encoding systems
Authors: Imai Hideki , Nagasaka Yasuji 
Published: July 2007

AbstractDouble encoding is a method by which a new code is constructed by twofold encoding with two codes. Using this method, a code with excellent error‐correcting capabilities can be constructed from relatively simple codes. The decoding can also be made simpler compared with a single code with the same code length and the same error‐correcting performance. Both random and burst errors can be corrected. This paper describes a general, practical decoding method for use in a double‐encoding system. Algebraic decoding is used in both the first and the second stages, but the detailed information obtained in the first decoding is fully utilized in the second stage: the usual error‐correcting method is applied in the first decoding and a Chase algorithm is applied in the second decoding. A decoding system which is a practical simplification of the above method is also proposed. The proposed methods are compared with widely‐used conventional systems in terms of the decoding error rate; it is shown that the decoding error rate can drastically be improved.
Dielectric and conductor losses in coplanar waveguides
Authors: Koshiji Kohji , Shu Eimei , Miki Shichiro 
Published: July 2007

AbstractConductor and dielectric losses in a coplanar waveguide are analyzed and the results are verified experimentally. Since the waveguide is made of two conductors, TEM transmission is assumed and the Laplace equation for the potential distribution in the waveguide cross section is solved. From the resultant potential distributions, the current distributions on the conductor surfaces and the conductor loss are obtained. We also obtain the effective dielectric constant, which expresses the electrical effect exerted on the waveguide by the dielectric substrate. From this quantity, the dielectric loss is derived. The Laplace equation is solved numerically on a computer using the successive overrelaxation method. Only one quarter of the cross section is analyzed due to symmetry, so that computation time and memory requirements are reduced. The experiment verification of these results involves measurement of Q of a resonator consisting of a coplanar waveguide. The difference between the theoretical and experimental values is less than 25% for the conductor loss and less than 6% for the dielectric loss.
A control method of variable resonance type adaptive equalizer for a digital radio system
Authors: Matsue Hideaki , Yoshida Teruaki , Morita Kozo 
Published: July 2007

AbstractIn a microwave‐band highly efficient digital radio system, transmission characteristics deteriorate remarkably due to multipath fading generated on propagation paths. This paper describes a control method of adaptive equalizer using a variable resonance‐type equalizer circuit which has been developed for the correction of multipath fading. Since a received power spectrum is used for the detection of fading characteristics, the bandwidth and response speed of the detector are optimized first and, then, its control algorithm is investigated. A microcomputer is introduced for the first time in the control circuit, enabling advanced control. As a result, a well‐convergent algorithm, taking advantage of equalizing circuit characteristics, is developed.Laboratory experiments, in a 200 Mbit/s 16 QAM (transmission speed, 50 Mband) digital radio system, using a two‐ray fading simulator confirmed that the control method has good convergency and the adaptive equalizer has sufficient equalization effects.
