Using Weighted Hospital Service Area Networks to Explore Variation in Preventable Hospitalization

Using Weighted Hospital Service Area Networks to Explore Variation in Preventable Hospitalization.

OBJECTIVE To demonstrate the use of multiple-membership multilevel models, which analytically structure patients in a weighted network of hospitals, for exploring between-hospital variation in preventable hospitalizations. DATA SOURCES Cohort of 267,014 people aged over 45 in NSW, Australia. STUDY DESIGN Patterns of patient flow were used to create weighted hospital service area networks (w...

fault location in power distribution networks using matching algorithm

چکیده رساله/پایان نامه : تاکنون روش‏های متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روش‏ها در شبکه توزیع به دلایلی همچون وجود انشعاب‏های متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تک‏فاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...

Preventable hospitalization and access to primary health care in an area of Southern Italy

BACKGROUND Ambulatory care-sensitive conditions (ACSC), such as hypertension, diabetes, chronic heart failure, chronic obstructive pulmonary disease and asthma, are conditions that can be managed with timely and effective outpatient care reducing the need of hospitalization. Avoidable hospitalizations for ACSC have been used to assess access, quality and performance of the primary care delivery...

Hard real-time communications with weighted round robin service in ATM local area networks

In this paper, we address issues related to providing guaranteed real-time communication in ATM local area networks. We concentrate on output link scheduling because it plays a critical role in meeting message deadlines. We are particularly interested in the weighted round robin scheduling policy because of its simple design and implementation. To use weighted round robin scheduling for hard re...
