This study was conducted with an aim to investigate the impact of store atmospherics on consumer buying behavior at D-MART store in Vadodara District. With the retail industry becoming highly competitive as a result of many convenience stores cropping up in the city, the bigger brands have to put in that extra effort to increase footfalls and convert footfalls into sales. What ways can the retailers adopt to increase their top lines remains an Achilles heel for many retailers. Can store...

In the last report we focused on the study of 3D synthetic jets of moderate jet aspect-ratio. Jets in quiescent and cross-flow cases were investigated. Since most of the synthetic jets in practical applications are found to be of large aspect ratio, the focus was shifted to studying synthetic jets of large aspect ratio. In the current year, further progress has been made by studying jets of aspect ratio 8 and infinity. Some other aspects of the jet, like the vorticity flux is looked into apart...

The improvement of the reliability of IFF systems is being studied. This report is an investigation of the communication aspects of the ground-to- air IFF system. Factors affecting reliability are atmospherics, receiver noise, inadequate space resolution, garbling, and jamming and deception on the part of the enemy. The last factor was given prime consideration. Examples are given of the use of redundancy coding to improve the reliability of pulse-train transmissions in the presence of noise,...

A physical theory of propagation of long waves was developed which provides methods of computation and make it possible to compare theory with experiment. Also, new experimental results were obtained from 2 sources: direct experiments with radio waves, and indirectly by using atmospherics. Therefore, at present, it is not necessary to be limited to radio waves created by radio arrangements only, but it becomes possible to broaden the investigation down to electromagnetic waves at the lowest...

Observations of instantaneous frequency and angle-of-arrival changes during solar flares suggest that new ionization is introduced initially somewhere just above the E region--very probably in the height region 120 to 140 km, although even higher heights are possible. This initial ionization may or may not be followed by the generation of ionization in the absorbing D region. The time variation of height at which solar-flare-induced ionization is released, suggests that the ionization-producing...

A general theory to explain the propagation characteristics of very low frequency (VLF) waves which travel between the earth and the ionosphere is presented. From this theory, two methods for range determination are suggested by analyzing the received energy spectrum. The magnitude and the cause of the errors which can be expected in both range and azimuth measurements are predicted.

A short theoretical investigation is made of the factors involved in the charging and discharging process of an airborne helicopter. The dominant factor in keeping this charge small is a short discharge time constant compared with the charging time constant. Practically, the only means of controlling the discharge time constant is by controlling the resistivity of the air. Possible methods are discussed and evaluated. It is concluded that only corona discharge systems seem feasible at this...

Instrumentation was developed to secure noise data in the 3 to 50 cps portion of the spectrum and, at the same time, to seek evidence of the Schumann frequencies in this region. A frequency translation technique is employed during recording. During playback, the data is again translated and restored to its normal position in the spectrum. A test signal is used to ensure that in the record mode the gain is maintained within 1.2 db. Under this restriction, test tapes recorded at frequencies in...

Evidence of earth-ionosphere cavity mode frequencies was experimentally obtained. The results indicate that the lower mode frequencies are f1 is approx. 8.5 cps, f2 is approx. 15.5 cps, and f3 is approx. 22.6 cps. The comparatively small amount of data secured during the evening hours precludes noting any change in the mode frequencies due to changes in ionosphere height or conductivity.

Geographical, seasonal, and day-to-day variations in the vertical distribution of atmospheric density for altitudes up to 30 km are analyzed. Variability is least at 7 to 8 km, the isopycnic level, where densities do not depart from the standard by more than 1 or 2 percent in any season or area. Between 24 and 26 km, density changes little with latitude but markedly with season. At the level of greatest seasonal variability, around 15 km, the relative departures from standard of mean seasonal...

Atmospherics formed from lightning discharges are a convenient object for investigating long and super-long electromagnetic waves. In previous works it was shown that the phase velocity of the electromagnetic waves comprising atmospherics and the effective conductivity of the lower ionosphere can be determined by analyzing the phase (and to some extent the amplitude) characteristics of single atmospherics. A reasonably correct solution of the opposite problem was also of great interest, viz.,...

The variability of wind from 200 to 2000 feet above the surface at White Sands Missile Range was studied. Wind variability as a function of time (3.5, 4.0, 8.0, 10.0, and 11.5 minutes) is presented. Data for the study were obtained from double-theodolite pilot-balloon observations. The absolute mean and the standard deviation of the difference in wind velocity for 100-foot intervals from 200 to 2000 feet indicate the magnitude of the change that can be expected in a given time increment for a...

The backscattering of a uniform plane wave by a conductor in a semi- infinite dissipative medium is discussed. The conductor is assumed to act as both an electric and a magnetic dipole with mo ments which are obtained from the electric magne tic polarizabilities of the conductor, respec tively. Using these induced moments, expressions are derived for the backscattered electric field at a point on the surface of the dissipative half-space directly above the dipoles. Both harmonic and transient...

In 1963, the operating frequency of the VLF transmitting station NPG, located near Seattle, Washington, was changed from 18.6 kc to 24.0 kc. Tests were conducted to predict the communication reliability of the NPG 24.0 kc transmissions in the western Pacific Ocean area. Comparison of the experimental and predicted data show very good agreement. The received field strengths, as observed, were slightly higher than predicted. The predicted atmospheric noise levels showed very close agreement with...

Emission spectrograms with 0.2 Angstrom resolution have been recorded for shock-heated air, oxygen, nitrogen, and nitrous oxide for temperatures from 6,000 to 12,000 degrees Kelvin and densities from 0.1 to 3.3 normal. The beta and gamma band systems of nitrous oxide were not observed in these spectra, leading to the conclusion that Bethke's f-values are at least a factor of two too high. A SACHA peak-to-minimum fit to the experimental profile of singly ionized molecular nitrogen 3,914 Angstrom...
