in this paper, we propose a technique of artificial intelligence called adaptive neuro fuzzy inference system (anfis) for canceling maternal electrocardiogram (mecg) in fetal electrocardiogram extraction (fecg).this technique is used to estimate the mecg present in the abdominal signal of a pregnant woman. the fecg is then extracted by subtracting the estimated mecg from the abdominal signal. p...

OBJECTIVE To establish the rate of and reasons for cancellations of surgery on the scheduled day in an Australian hospital. DESIGN Prospective survey. SETTING Major metropolitan tertiary hospital, 13 May to 15 November 2002. MAIN OUTCOME MEASURES Proportion of operations cancelled on the day of surgery, obtained each day from the operating theatre list and a separate list of additions and...

in this work we consider conjugacy of elements and parabolic subgroups‎ ‎in details‎, ‎in a new class of artin groups‎, ‎introduced in an earlier work‎, ‎which may contain arbitrary parabolic subgroups‎. ‎in particular‎, ‎we find‎ ‎algorithmically minimal representatives of elements in a conjugacy class‎ ‎and also an algorithm to pass from one minimal representative to the others‎.

Objective: to characterize the access to surgical assistance in Brazil. Method: documentary study, with a quantitative approach, developed from information of the Caixa Preta da Saúde [Health Black Box] database, of the Brazilian Medical Association. Results: in the one-year period 3773 cases related to health care in Brazil were recorded. There were 458 (12.3%) records on surgical assistance. ...

Late cancellations of scheduled elective surgery limit the ability of the surgical care service to achieve its goals. Attributes of these cancellations differ between hospitals and regions. The rate of late cancellations of elective surgery conducted in Hamad General Hospital, Doha, Qatar was found to be 13.14% which is similar to rates reported in hospitals elsewhere in the world; although ele...

BACKGROUND The cancellation of planned surgeries causes prolonged wait times, harm to patients, and is a waste of scarce resources. To reduce high cancellation rates in a Norwegian general hospital, the pathway for elective surgery was redesigned. The changes included earlier clinical assessment of patients, better planning and documentation systems, and increased involvement of patients in the...

BACKGROUND The cancellation of planned surgery harms patients, increases waiting times and wastes scarce health resources. Previous studies have evaluated interventions to reduce cancellations from medical and management perspectives; these have focused on cost, length of stay, improved efficiency, and reduced post-operative complications. In our case a hospital had experienced high cancellatio...

In this letter we comment on partial parallel interference cancellation as discussed in the above paper by Divsalar et al. The aforementioned work showed that by multiplying symbol estimates by a factor less than unity in early stages of cancellation, the performance of parallel cancellation can be improved relative to full (“brute force”) cancellation. In this letter we analyze the improvement...
