Virtual software engineering laboratories in support of trade-off analyses

Due to demanding customer needs and evolving technology, software organizations are forced to trade individual functional and non-functional product quality profiles against other factors such as cost, time, or productivity. The ability to influence or even control these factors requires a deep understanding of the complex relations between process and product attributes in relevant contexts. Base

Correlates of Nine-Month Retention following Interim Buprenorphine-Naloxone Treatment in Opioid Dependence: A Pilot Study.

Interim medication-only treatment has been suggested for the initiation of opioid maintenance treatment (OMT) in opioid-dependent subjects, but this rarely has been studied using buprenorphine instead of methadone. Following a pilot trial assessing interim buprenorphine-naloxone treatment in order to facilitate transfer into OMT, we here aimed to study retention, and potential correlates of retent

On-line Heart Rate Monitoring Using the Extra-corporeal Pressure Sensors of a Dialysis Machine

Heart rate can be extracted from the extracorporeal venous pressure signal of a dialysis machine. The results are of comparable accuracy and reliability to the ones obtained by the PPG reference signal from a pulse oximeter. Difficulties that occur during heart rate estimation were determined, and some can be overcome by a slight adjustment of blood flow rate. The described techniques, after being

Media and civil society in China: Community building and networking among investigative journalists and beyond

Although Chinese journalists are not able to create their own independent organisations, they are engaging in informal networking on-line and off-line that has created a strong sense of community among investigative journalists in particular. Through sharing experiences, stories, and struggles, journalists create a collective identity and define their roles in society. Earlier studies of Chinese j

A 4.6GHz PLL with automatic frequency calibration based on multiple-pass ring oscillator

A good-performance high-frequency Phase Locked Loop using a ring oscillator is described. A Voltag e Controlled Oscillator with automatic calibration of frequency fluctuated by proce ss and tempe rature variations is propo sed. The VCO adopts new multiple-pass loop to improve frequency with unchangeable stages (phases). The circuit is implemented with TSMC O. I8um standard CMOS technology and powe
