We report on building a computational model of romantic relationships in a corpus of historical literary texts. We frame this task as a ranking problem in which, for a given character, we try to assign the highest rank to the character with whom (s)he is most likely to be romantically involved. As data we use a publicly available corpus of French 17th and 18th century plays (http://www.theatre-...
The material removal rate (MRR) plays a critical role in the chemical mechanical planarization (CMP) process semiconductor industry. Many physics-based and data-driven approaches have been proposed to-date to predict MRR. Nevertheless, most of them neglect underlying equipment structure containing essential interaction mechanisms among different components. To fill gap, this paper proposes nove...
On-chip switching of a silicon nitride micro-ring resonator based on digital microfluidics platform.
We demonstrate the switching of a silicon nitride micro ring resonator (MRR) by using digital microfluidics (DMF). Our platform allows driving micro-droplets on-chip, providing control over the effective refractive index at the vicinity of the resonator and thus facilitating the manipulation of the transmission spectrum of the MRR. The device is fabricated using a process that is compatible wit...
Abstract—Productivity and quality are two important aspects that have become great concerns in today’s competitive global market. Every production/manufacturing unit mainly focuses on these areas in relation to the process, as well as the product developed. The electrical discharge machining (EDM) process, even now it is an experience process, wherein the selected parameters are still often far...
The nite sample properties of three semiparametric estimators, several versions of the modiied rescaled range, MRR, and three versions of the GHURST estimator are investigated. Their power and size for testing for long memory under short-run eeects, joint short and long-run eeects, heteroscedasticity and t-distributions are given using Monte Carlo methods. The MRR with the Bartlett window is ge...
The optimization of parameters considering multiple performance characteristics of the EDM process for SS 304 using the GRA is presented. Performance characteristics including MRR, TWR, and OC are chosen to evaluate the machining effects. Those process parameters that are closely correlated with the selected performance characteristics in this study are the pulse-on time, current, and voltage. ...
This paper describes research on earth-space attenuation on a microwave communications link set up at Belgaum-RC Nagar (Karnataka State), India, during July to September, each year. The rain data secured from India Meteorological Department, Bangalore has been used for analysis with the live data of rainfall recorded with the aid of two tipping bucket rain gauges, and a disdrometer. A simple mo...
In this paper, we demonstrate a novel dual-pump approach to generate robust optical frequency comb with varying free spectral range (FSR) spacing in a CMOS-compatible high-Q micro-ring resonator (MRR). The frequency spacing of the comb can be tuned by an integer number FSR of the MRR freely in our dual-pump scheme. The dual pumps are self-oscillated in the laser cavity loop and their wavelength...
Electrical discharge machining is assessed on the basis of Material Removal Rate (MRR), Tool Wear Rate (TWR), and Surface Roughness (SR). Process parameters that mostly affected the EDM Process are Pulse on Time, Pulse off Time, Discharge Current, Arc Gap and Duty Cycle. This paper reviews research for the optimization and improvement of various performance parameters measured in the experiment...
