A new method for predicting timing jitter caused by device noise in current-mode logic (CML) frequency dividers is presented. Device noise transformation into jitter is modeled as a linear time-varying (LTV) process, as opposed to a previously published method, which models jitter generation as a linear time-invariant (LTI) process. Predictions obtained using the LTV method match jitter values ...

Engine performance depends on two main factors of engine speed and ignition time. Ignition timing can affect engine life, fuel economy and engine power. In this paper, to study engine performance of Peugeot 206 TU3A with comparison ratio of 10.5:1 and displacement of 1361CC in MATLAB software, a two-zone burned/unburned model with the fuel burning rate described by aWiebe function was used for ...

Primary malignant brain tumors (BT) are the most common and aggressive malignant brain tumor. Treatment of BTs is a daunting task with median survival just at 21 months. Methods of localized delivery have achieved success in treating BT by circumventing the blood brain barrier and achieving high concentrations of therapeutic within the tumor. The capabilities of localized delivery can be enhanc...

The tough competition among automotive companies creates a high cost pressure on the OEMs. Combined with shorter innovation cycles, testing new safety-critical functions becomes an increasingly difficult issue [4]. In the automotive industry about 55% of breakdowns can be traced back to problems in electronic systems. About 30% of these incidents are estimated to be caused by timing problems [7...

Jackson et al describe a complex timing cycle interaction in a patient with a dual-chamber implantable cardioverter– defibrillator. The intracardiac electrograms provided along with their description of an algorithmic approach to differential diagnosis is ripe with teaching points typical of the bedside rounds of yesteryear. Complex cases require not only meticulous logical analysis of the avai...

Power is widely considered the only real limiter for Moore’s Law in the next decade [Gelsinger, 2004]. Indeed, IBM CTO B. Meyerson has claimed that CMOS process scaling has already stopped between 130nm and 90nm due to power limitations [Clarke, 2004]. Existing methods for physical synthesis, however, have primarily targeted timing closure and are inadequate to meet the challenge of low-power p...

A scalable laser-based timing analysis technique we call laser assisted device alteration (LADA) is introduced for the rapid isolation and analysis of defect-free performance limiting circuits in advanced flip-chip packaged microprocessors and other complex IC’s. The technique, which has been demonstrated to be widely applicable to production level as well as motherboard/system level testing, u...

The control system (TICS) for the test interferometer being built to support the development of the Atacama Large Millimeter Array (ALMA)[1] will itself be a prototype for the final ALMA array, providing a test for the distributed control system under development. TICS will be based on the ALMA Common Software (ACS)[2] (developed at the European Southern Observatory), which provides CORBAbased[...
