Interactive voice response technology for telephony system

Speech is tbe primary means of communication between people. For reasons ranging from technology curiosity about the mechanism for mechanical realization of human speech capabilities. To the desire to automate simple tasks inherently requiring human-machine interactions. There have been many interesting advances and developments since the invention of the first speech recognizer at Bell Labs in the early 1950's. Besides inventing useful automated speech recognizers, scientislS and researchers' contribUlions were to produce emeienl algorilhms lhal help 10 pnxlucc beller quality aulomated speech recognition systems. and improve lhe accuracy and malching standanrd in order to make the syslems more usefu

Principle component analysis of organoleptic acceptability on Cocos™ emulsion product

Cocos™ Emulsion is new food emulsion product that made of virgin coconut oil (VCO). A sensory analysis was conducted among targeted consumers, which were 150 schoolchildren (age 4 - 12) and 100 adult panelists (age 21 - 60). The principle component analysis (PCA) was applied to assess the organoleptic acceptability of public and schoolchildren on this novel product. In summary, both adult and schoolchildren panelists showed a significant preference (P < 0.05) toward Cocos™ Emulsion than VCO for both sensory attributes of taste and odour, as it was palatable. The scores plot of sensory attributes among all panelists were found highly scattered around, indicating no age-dependent preference on the sensory rating of each attributes

Effects of selected herbs and vegetables on the nutritional quality of beef burger and rat bioassay

Rat bioassay was used to evaluate the nutritional quality of beef burger as influenced by the addition of selected herbs and vegetables. The selected herbs and vegetables used were pucuk ubi (Mannihot esculenta), pucuk gajus (Anacardium occidentale), pegaga (Centella asiatica) and jantung pisang (Musa paradisiaca) as treatment group with casein and skimmed milk as reference. The rats were fed with herbs and vegetables at the rate of 0.5 (low dose) and 25 (high dose) g/kg body weight. The samples were analyzed for proximate analysis, protein quality and protein digestibility. The rats fed with pucuk ubi (high dose) (364.30 ± 25.34 g) indicated the highest mean of increased body weight (121.05 ± 14.65 g) while rats fed with skimmed milk (310.98 ± 18.92 g) showed the lowest mean increase in body weight (88.33 ± 14.25 g). As for the Protein Efficiency Ratio (PER) value, all the rats fed with herbs diet showed PER values that were significantly lower (p<0.05) compared to the casein. As for the in vivo apparent protein digestibility test, casein showed the highest digestibility value (86.33 ± 4.20) while pucuk gajus (high dose) (59.59 ± 5.41) showed the lowest. As for the in vitro digestibility analyses, casein indicated the highest value for in vitro digestibility (93.84 ± 0.33). Administration of herbs and vegetables at low and high doses show significant effects (p<0.05) on nutritional quality of beef burger. In conclusion, it was found that antinutritional factors in selected herbs and vegetables might affect the nutritional quality of beef burger

A comparative evaluation of the performances of three built-in-storage-type solar water heaters

Three built-in-storage-type solar water heaters of equal volume were tested under identical conditions for performance evaluation. One of these water heaters was rectangular and the other two were triangular. One of the triangular water heaters had a baffle plate and the other did not. The triangular water heater with baffle plate was found to be not superior to the rectangular one in efficiency during the heating period. However, it was more efficient during the cooling period. The triangular water heater without the baffle plate was found to be the most efficient one during both the heating and the cooling periods

Solar domestic water heating in Turkey

In this report we discuss the present situation of solar water heating for domestic supplies in Turkey and give the results of a computer analysis for nine distinct regions. The analyses are carried out for four typical days of the four seasons and also on a monthly base. The results show that detailed initial work must be carried out before installing the system to determine the optimized collector area. Such analysis can provide efficient using of the Sun's energy as well as economical benefits in the initial investments and long term utilization

Dissipative behavior and gamma-irradiation of silver-sheathed Bi1.8Pb0.4Sr2Ca2Cu3Ox tape

Dissipative mechanisms in Bi1.8Pb0.4Sr2Ca2Cu3Ox tapes were investigated using magnetoresistance measurements and V-I characteristics. A considerable broadening of the resistive transition in applied magnetic field was observed up to a field of 0.5 T. The temperature and magnetic field dependence of the resistance R(T,B) were fitted to the Arrhenius relation and from which the magnetic field dependence of the pinning energy U-0(B) similar to B-alpha with alpha approximate to 0.9 was derived. The variations of the critical current densities J(c) with temperature and magnetic field before and after gamma-irradiation were also studied. The temperature dependence of J(c)(T) was fitted to the relation J(c)(T) similar to (1 - T/T-c)(n) with n = 1.9 and discussed in terms of thermally activated flux flow (TAFF). However, J(c)(B) results were explained based on the weak links, grain boundaries, and Josephson junctions in which it shows a power law behaviour J(c)(B) similar to B-0.5. At relatively low temperatures and magnetic fields, the critical current density was increased with a gamma-irradiation up to a dose of 100 MR
