The Poor

This study investigated the effects of stimulability on the articulation of cluster nested /s/ in high- and low-frequency clusters and words. A good stimulability group and a poor stimulability group of /s/-defective seven-year-old children were investigated. Statistical analysis did not reveal significant differences between the articulatory performances of the two groups on words or clusters occurring with high or low frequency. Subjects in the good stimulability group obtained significantly fewer errors on the test stimuli than did subjects in the poor stimulability group. Correlational analyses indicated that stimulability was positively correlated with correct numbers of /s/ productions in both clusters and words occurring with both high and low frequency. Subjects' spontaneous /s/ errors on the Templin-Darley screening test were not found to be correlated with their stimulability scores or their imitative /s/ productions in words and clusters occurring with high or low frequencies.

Read Range

In today’s era RFID system plays a key role in the field of asset tracking but its maximum read range or detectability may get degraded due to the challenges which are being provided by varying atmospheric conditions. So, to study the effect of these challenging atmospheric conditions, experimental investigation and statistical analysis of RFID system detectability has been carried out. Varying surrounding temperature, humidity and the presence of soil layer thickness in between RFID reader and tag and its five different grain sizes were considered as input parameters. All these observations were carried out for three different soils i.e. sandy soil, Silt and clay. Execution of test was carried out according to the MINITAB 17 tool. According to ANOVA analysis as well as from interaction plot it was found that soil layer thickness have more impact on RFID system read range and R2 value was found to be 96.91%, 99.64% and 99.78% for RRSS, RRS and RRC respectively. Composite desirability of optimization was found to be 0.8425. Optimum values of process parameters Temperature, Soil Layer Thickness, Relative Humidity and Soil Grain Size were found to be 303.3°K, 2.5 cm, 40.1 %, 1.92 mm respectively. Best values of responses were found to be 10.94 cm for (Read Range in presence of Clay); 11.02 cm (Read Range in presence of Silt) and 10.97 cm (Read Range in presence of Sandy Soil).

Short Period

Abstract The approximate hexagonal configuration of LASA subarrays enables their use as omnidirectional arrays. This property is used to study the phase velocity of short-period seismic noise at different frequencies. It is found that the noise in the low-frequency band consists mainly of surface waves traveling with average velocities in the range 3.0 to 3.5 km/sec. The high-frequency noise, in the band 0.45 to 1.0 Hz, has an average velocity of about 6.0 km/sec. It is quite likely that the high-frequency noise has the nature of locally-generated body waves. Statistical analysis of Pg velocities observed during a crustal refraction experiment at LASA lends support to this hypothesis.
