Conversational Case-Based Reasoning (CBR) systems assist their users in formulating queries for case retrieval. Existing textual CBR (TCBR) systems support conversation using only hand-crafted features and indices. However, to be practical, TCBR systems that require conversation should automatically generate their features. This is a difficult problem because TCBR applications routinely involve...

BACKGROUND The limited availability of pediatric rheumatologists for teaching in pediatric residency programs negatively impacts resident education about rheumatology. At present, there are no educational websites available for trainees to learn about pediatric rheumatology. We are planning to develop an interactive web-based teaching module to improve resident learning about rheumatology ("POI...

background and purpose: studies have shown the advantages of e-cme programs. developing case-based e-cme activities, one of the popular formats of e-cme programs, is difficult and time consuming. in this article we describe our experience of performing instructional system design for creating case-based e-cme contents.  methods: we performed a five-step instructional system design (i.e. system ...

the current internet inherently has a degree of survivability due to the connection less ip protocol. dynamic routing protocols are designed to react to faults by changing routes when routers learn about topology changes via routing information updates (e.g., link status advertisements). loss of quality of service (qos) has not been an issue because current internet traffic is the best-effort. ...

selective harmonic elimination (she) is a powerful modulation scheme aims to find the required switching angles in order to eliminate the number of undesired harmonics. she is a complicated problem which consists of several nonlinear equations which have multiple local minima. in order to eliminate the higher number of undesired harmonics and as a result reducing the total harmonic distortion (...

this article reports on the findings of a study that investigated the impact of manipulating task performance conditions on listening task performance by learners of english as a foreign language (efl). the study was designed to explore the effects of changing complexity dimensions on listening task performance and to achieve two aims: to see how listening comprehension task performance was aff...

Imagine you have traveled to an unfamiliar city. Before you start your daily tour around the city, you need to know a good route. In Network Theory (NT), this is the traveling salesman problem (TSP). A dynamic programming algorithm is often used for solving this problem. However, when the road network of the city is very complicated and dense, which is usually the case, it will take too long fo...
