Abstract Fetal alcohol-spectrum disorder (FASD) is underdiagnosed and often misdiagnosed as attention-deficit/hyperactivity (ADHD). Here, we develop a screening tool for FASD in youth with ADHD symptoms. To the prediction model, medical record data from German University outpatient unit are assessed including 275 patients aged 0–19 years old or without 170 old. We train 6 machine learning models based on 13 selected variables evaluate their performance. Random forest yield best...
MAFIA Version 4.0 is an almost completely new version of the general purpose electromagnetic simulator known since 13 years. The major improvements concern graphical user interface based on state art technology as well a series solvers for physics problems. now covers heat distribution, electro-quasistatics, S-parameters in frequency domain, particle beam tracking linear accelerators, acoustics and even elastodynamics. that were available earlier versions have also been improved and/or...
A 15-year-old, female, formerly obese adolescent was referred to our day care clinic due self-induced massive weight loss and depressive symptoms. Intense treatment, additional dialectical behavioral therapy psychopharmacological treatment prevented further improved her affective state. Due remaining anorexic symptoms such as body image distortion, outpatient psychotherapeutic is continued. This case report indicates the importance of research on diagnostic crossover from obesity atypical...
By exciting a broadband pulse in the time domain and performing fast Fourier transform on sampled data it is possible to obtain scattering parameters for broad frequency range with one single calculation. This known technique, valid non-dispersive waveguides, extended homogeneously loaded dispersive waveguides. In most cases this technique outperforms approach by orders of magnitude terms calculation time. We will give short introduction method present some examples.< <ETX...
Zusammenfassung: Hintergrund: Mit einer geschätzten Prävalenz von 1 bis 2 pro 100 Personen sind Fetale Alkoholspektrumstörungen (Fetal Alcohol Spectrum Disorders [FASD]) in Europa häufig und verbunden mit hohen Belastung für Menschen FASD, deren Angehörige sowie die Gesellschaft. Es handelt sich um komplexe Erkrankungen Einschränkungen auf unterschiedlichen Ebenen inklusive Verhalten, Leistungsfähigkeit Selbständigkeit. Zur Diagnostik FASD im Kindes- Jugendalter steht eine S3-Leitlinie zur...
We present the results of a field-based 3D time domain simulation high pincount board connector. The are crosstalk for large frequency range and field patterns inside structure at certain frequencies. computer code we use is based on Finite-Integration-Technique (FIT). scattering parameters in 0-3 GHz, reflection near-end ramp (both measurement simulation), obtained 3 GHz.
The simulation of electromagnetic fields inside a cylindrical cavity, which is connected by rectangular iris to standard waveguide presented. calculations for loaded and unloaded cases are based on finite integration method algorithm. results obtained agree closely with those measurements.
Scattering parameters are important characteristics of rf‐devices such as couplers. Usually the calculation these is done in frequency domain separately for each single point. The way described here to excite a broadband pulse time and perform fast Fourier transform on sampled data. With this method it possible obtain scattering broad range with one calculation. resolution given by number steps (and step size) usually much higher than that Thus resulting spectrum contains more information...
Summary from only given, as follows. The program group MAFIA which solves Maxwell's equations has been further improved by the inclusion of new programs, integration both two and three dimensional modules under a unified user interface extension pre- post-processor capabilities. In present release, 3.1, module for calculation eddy currents in solid or laminated iron cores is latest addition to family codes, particle-in-cell solve motion parallel with electromagnetic field equations, are also...
