The DAB (Data Acquisition Board) is a key component of the VMPHA (Virtual Multi-channel Pulse Height Analyzer). In order to assist the design of the VMPHA, the influence of the DAB on the performances of the VMPHA has been studied through the method of theoretical analysis in this paper. The Sampling Rate, the LSB (Least Significant Bit) and the Data Transfer Rate of the DAB have decisive effects on the performance of the VMPHA. The Sampling Rate and the LSB are the two main factors that determine the energy resolution which is one of the most important performance indicators for the VMPHA. Another most important performance indicator for the VMPHA, the number of channels, is determined by the LSB alone. Moreover, the relationship among the three key performance parameters of the DAB is mutual influence. At the end of the paper, the selection method of the DAB for developing a VMPHA is summarized and presented.

The conventional discrete Fourier transform can be extended to a discrete Extended Fourier transform (EFT). The EFT allows to work with discrete data in close analogy to the optical bench, where continuous data are processed. The EFT includes a capability to increase or decrease the resolution in Fourier space (thus the argument that CCD cameras with a higher number of pixels to increase the resolution in Fourier space is no longer valid). Fourier transforms may also be shifted with arbitrary increments, which is important in electron holography. Still, the analogy between the optical bench and discrete optics on a computer is limited by the Nyquist limit. In this abstract we discuss the capability with the EFT to change the initial sampling rate si of a recorded or simulated image to any other(final) sampling rate sf.

This article details the process of self-reflection applied to the use of traditional performance indicator questionnaires. The study followed eight speech-language pathology graduate students enrolled in clinical practicum in the university, school, and healthcare settings over a period of two semesters. Results indicated when reflection was focused on students' own clinical skills, modifications to practice were implemented. Results further concluded self-assessment using performance indicators paired with written reflections can be a viable form of instruction in clinical education.

Background: The default mode interference hypothesis ( Sonuga-Barke & Castellanos, 2007 ) predicts (1) the attenuation of very low frequency oscillations (VLFO; e.g., .05 Hz) in brain activity within the default mode network during the transition from rest to task, and (2) that failures to attenuate in this way will lead to an increased likelihood of periodic attention lapses that are synchronized to the VLFO pattern. Here, we tested these predictions using DC-EEG recordings within and outside of a previously identified network of electrode locations hypothesized to reflect DMN activity (i.e., S3 network; Helps et al., 2008 ). Method: 24 young adults (mean age 22.3 years; 8 male), sampled to include a wide range of ADHD symptoms, took part in a study of rest to task transitions. Two conditions were compared: 5 min of rest (eyes open) and a 10-min simple 2-choice RT task with a relatively high sampling rate (ISI 1 s). DC-EEG was recorded during both conditions, and the low-frequency spectrum was decomposed and measures of the power within specific bands extracted. Results: Shift from rest to task led to an attenuation of VLFO activity within the S3 network which was inversely associated with ADHD symptoms. RT during task also showed a VLFO signature. During task there was a small but significant degree of synchronization between EEG and RT in the VLFO band. Attenuators showed a lower degree of synchrony than nonattenuators. Discussion: The results provide some initial EEG-based support for the default mode interference hypothesis and suggest that failure to attenuate VLFO in the S3 network is associated with higher synchrony between low-frequency brain activity and RT fluctuations during a simple RT task. Although significant, the effects were small and future research should employ tasks with a higher sampling rate to increase the possibility of extracting robust and stable signals.

Introduction. Slow fl uctuations in the volume and pressure of liquids in the cranial cavity have been known for a long time and have been studied for more than 100 years. However, their quantitative indicators and their practical signifi cance remain unclear until now due to the diffi culties of research. Nevertheless, it was found that they were connected with the brain activity, which made it possible to use them as one of the physiological indicators in studying the problems of manned space fl ights. Goal of research — to study the possibility of using spectral analysis of slow fl uctuations of the volume of liquids inside the cranium in order to realize the quantitative assessment of their indicators with the use of modern microelectronics and computer technology.Materials and methods. In order to solve this problem we created a complex, in which rheoencephalograph-RG-01 («Mizar») was used as a converter-modulator of physiological signals into electrical oscillations. The device was connected with the ADC (Firm «ADIstrument»), Its software allows to calculate the spectrogram with a sampling rate of 128 kHz. Studies were conducted on volunteers of younger, middle and older age groups. The respiratory rate and the electrocardiography were registered together with the rheoencephalography. Electrodes were fi xed on the volonteers′ fronto-mastoid area.Results. Slow fl uctuations the cranium representan independent physiological phenomenon. The most considerable and valuable were fl uctuations in 0,1–0,3 Hz. It was found that current frequency of 100 or 200 kHz and frequency for quantization of 80–100 kHz was optimal for performing their spectrograms. The structure of such diagram consists of 4–7 peaks with amplitude of 0,4–0,7 units compared with REG pulse amplitude. They depend on age and are characterized by hemispheric asymmetry. Spectral diagrams of slow fl ucation inside cranium are representing inpendent physiological phenomenon. These fl uctuations are not connected by common origin, with heart activity and respiration. They are connected by nature with brain activity and PRM.Conclusion. Can be an informative method for diagnostic and assessment of general status of osteopathic patients well as for the assessment of mechanisms of action of some osteopathic techniques.

Fenomena yang diteliti pada UIN Syarif Hidayatullah Jakarta adalah sulitnya melihat capaian kinerja dan pengukuran kinerja. Oleh karena itu, UIN Syarif Hidayatullah Jakarta kesulitan mengambil keputusan dalam manajemen kinerja, sebelum menggunakan IKU, UIN Syarif Hidayatullah Jakarta menggunakan manajemen anggaran dalam penilaian dan pengukuran kinerja. Penelitian ini menggunakan metode kualitatif studi lapangan dengan pendekatan fenomenologi. Yang diteliti adalah pengalaman pola penggunaan Balanced Scorecard (BSC) IKU atau Key Performance Indicator (KPI)  UIN Syarif Hidayatullah Jakarta tahun 2018. Setelah adanya IKU di UIN Syarif Hidayatullah Jakarta dengan menggunakan Balanced Scorecard (BSC). penilaian kinerja dan ukuran kinerja ini bisa sebagai acuan capaiaan kinerja untuk Perangkingan Perguruan Tinggi di tingkat nasional maupun internasional, Laporan Akuntabilitas Kinerja Instansi Pemerintahan (LAKIP), Rencana Strategis (Renstra) dan Rencana Induk Pengembangan Kampus (RIBKA) atau Milestones dengan melihat indikator, target dan ukuran pada lapran tersebut.
