Effect of using seaweed (eucheuma) powder on the quality of fish cutlet.

Physico-chemical properties of Eucheuma, such as soluble solids (27.5+/-0.02%), water holding capacity (17.7+/-0.08g/g) and oil holding capacity (2.14+/-0.07g/g) were estimated as measures of its functionality. Eucheuma powder was used as an ingredient in the preparation of fish cutlet. Dried Eucheuma powder was added at levels of 5, 7.5, 10, 12.5 and 15% and physicochemical characteristics of fish cutlet were studied. Sensory evaluation showed that use of Eucheuma significantly (P<or=0.05) influenced texture of fish cutlet. It was found that Eucheuma powder could be incorporated into fish cutlet upto 10% level without adversely affecting the appearance, texture and acceptability.

Integrating the ECG power-line interference removal methods with rule-based system.

The power-line frequency interference in electrocardiographic signals is eliminated to enhance the signal characteristics for diagnosis. The power-line frequency normally varies +/- 1.5 Hz from its standard value of 50 Hz. In the present work, the performances of the linear FIR filter, Wave digital filter (WDF) and adaptive filter for the power-line frequency variations from 48.5 to 51.5 Hz in steps of 0.5 Hz are studied. The advantage of the LMS adaptive filter in the removal of power-line frequency interference even if the frequency of interference varies by +/- 1.5 Hz from its normal value of 50 Hz over other fixed frequency filters is very well justified. A novel method of integrating rule-based system approach with linear FIR filter and also with Wave digital filter are proposed. The performances of Rule-based FIR filter and Rule-based Wave digital filter are compared with the LMS adaptive filter.
