infonnation transferred, refer to the accompanying paper on This paper discusses the timing interface design subsystem in data transfer interface design [6]. To transfer state or timing DAME (Design A utomation of M icroprocessor based infonnation, a timing reference is always required. When systems, using an Expert system approach). The timing connecting two devices, this timing reference must...

Using high-bandwidth feedback, we have synchronized the pulse train from a mode-locked semiconductor laser to an external optical atomic clock signal and achieved what is to our knowledge the lowest timing jitter to date (22 fs, integrated from 1 Hz to 100 MHz) for such devices. The performance is limited by the intrinsic noise of the phase detector used for timing-jitter measurement. We expect...

A high-performance ASIC has been developed to serve as the interface for the 10-ns bus in the new AlphaServer 8000 series server systems from Digital. The CMOS standard-cell alternative (CSALT) technology provides a timing-driven layout methodology together with a correct-by-construction approach for managing the complex device physics issues associated with state-of-the-art CMOS processes. The...

original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...

Like the biological clock in the body, replication of each cell type (even different cells of the same organism) follows a timing program. Abnormal function of this timer could be an alarm for a disease like cancer. DNA replication starts from a specific point on the chromosome that is called the origin of replication. In contrast to prokaryotes in which DNA replication starts from a single ...

With technology steadily progressing into nanometer dimensions, precise control over all aspects of the fabrication process becomes an area of increasing concern. Process variations have immediate impact on circuit performance and behavior and standard design and signoff methodologies have to account for such variability. In this context, timing verification, already a challenging task due to t...

The capabilities of open-source software and microcontrollers were used to construct a device for controlled lighting experiments. The device was designed to ascertain whether individuals with certain color vision deficiencies were able to discriminate between the red and white lights in fielded systems on the basis of luminous intensity. The device provided the ability to control the timing an...

abstract: the new neonatal ventilation methods have been developed along with utilization of new technological tools.this device is synchronized with the patient’s respiratory efforts. the ideal synchronized breath needs to be synchronous with initiation, size, and termination of the breath without delay in detecting of initial resiratory effort by device .the synchrony of respiration contribut...

the purpose of this study was to examine the effect of self-control feedback on relative and absolute timing through observational and physical practices. participants (n=90) were randomly assigned to physical and observational practice (self-control, yoked, and instructor kr) groups. they practiced a sequential timing task, which required participants to press four keys (2, 6, 8, and 4) respec...
