In this paper it is attempted to predict the off-design performance of a jet engine. After a review of the governing equations, the off-design performance is investigated by two methods. In the first method, the component characteristic curves of the Gas Turbines are used. In the second method some design point parameters and the reference state conditions are employed. The results obtained by ...

conclusions given the significant prevalence of postoperative cognitive disorder and significant associatio n between the history of high blood pressure, c-reactive protein and preoperative creatinine and cognitive disorder, detection of patient’s clinical symptoms may improve diagnosis, treatment and prevention of this disorder. patients and methods in total, 171 patients who had undergone off...

balance sheet itself does not specify and show all the activities that a bank pays. because banks can do many swap contracts and obligations, exchange, and commitments outside of the balance sheet. to such activities and exchange that will not appear on the balance sheet, are saying off-balance sheet activities. these items are usually reported in the notes to the attached financial statements....

there are many treatment modalities available to acutely terminate incessant ventricular tachycardia with variable success rates, but some cases tend to prove refractory to all of them. we report a 59-year-old woman presenting with incessant ventricular tachycardia. echocardiography revealed a large true apical aneurysm and severe left ventricular dysfunction. the arrhythmia was controlled in t...

This paper proposes a method to capture user’s characteristics in a topic model frame, where user characteristics act as a latent variable that does not depend on texts. As it is obvious that different people possess different characteristics, they may perform differently even when they are facing the same document. These different characteristics can be showed as different views or different w...

In a corpus of expert tutoring dialogue, conversation that is considered to be “off topic” (non-pedagogical) according to a previous coding scheme is explored for its value in tutoring dynamics. Using the Linguistic Inquiry and Word Count (LIWC) tool, phases of tutoring categorized as “off topic” were compared with interactive problem solving phases to explore how the two differ on the emotiona...

A wavelength-selective 2-order 1-by-8-port optical multicast filter bank is demonstrated utilizing microring resonators, achieving ~2.6× faster roll-off than 1-order design while maintaining highly uniform responses among all eight drop ports. OCIS codes: (130.3120) Integrated optics devices; (230.5750) Resonators; (230.0250) Optoelectronics.

This paper presents a high-selectivity dual-band bandpass filter with independently-tunable passband frequencies. A tap-coupled structure is utilized to feed the two resonators at lower passband and a coupling structure is used to feed the two resonators at the upper passband. Two pairs of varactor-loaded resonators operating within two different frequency ranges, allow the independent passband...

OBJECTIVE To examine off-label use and costs of antihypertensive drugs in children by using a national sample of prescription claims. METHODS We conducted a cross-sectional study using the 2002 Medstat MarketScan Database, a national sample of outpatient prescription claims of children <or=18 years old enrolled in private, employer-sponsored health plans. Our main outcomes were off-label use ...
