Generation of spectrum compatible accelerograms

In this paper a new method is presented for generating earthquake accelerograms which have pre-established response spectra. The non-stationary random nature and other salient features of the accelerograms can be taken care of by the procedure developed. The method leads to a sample spectrum which lies above the given spectrum. The generation of records to suit several spectra simultaneously can also be handled by this approach. The method is detailed first. This is followed by several numerical examples

Influence of Mo6+ on Dielectric properties of Copper Ferrites

Two series of copper ferrites are prepared using the chemical compositional formula Cu1.0-3y Fe2.0-2x Mox + yO4.0. They are calcinated at 750 C and sintered at 950C.When x =y = 0.0, the ε′ of the basic copper ferrite is probably due to electronic exchange interactions of copper and iron ions as Cu2+↔ Cu1+ and Fe3+↔ Fe2+. The observed value of dielectric constant (є′) decreases as a function of substituent concentration (x) up to x = 0.20 and for further values of ‘x’ it found to increase. In the case of ‘C’ (x = 0) series ferrites є′ decreases with substituent concentration (y) up to y = 0.04, later it found to increase. The dispersion of ac resistivity with frequency is observed indicating their strong dependence on frequency as in the case of dielectric behaviour. These results are explained with different possible mechanisms

Frontal plane tibio-femoral alignment and its association with knee pain among patients with early osteoarthritis of the knee in a population presenting to a tertiary hospital in South India

Background: Frontal plane knee malalignment may increase the progression of knee osteoarthritis (OA) and worsen functional capacity.Methods: In our study, the aim was to find the correlation of frontal plane tibiofemoral alignment with knee pain in early OA knee patients. After meeting the inclusion and exclusion criteria, 195 patients with 314 knees (104 females, 91 males) were studied. Clinical and radiological measurements of frontal plane tibiofemoral alignment, using landmark of hip, knee, and ankle, compared with knee pain.Results: The accepted Statistical significance was p<0.05. Patients with 130 knees (41%) were normal alignment, and 184 knees (59%) were abnormal alignment. The mean±SD age in our study was 54.6±8.9 years. The mean±SD BMI in our study to be 25.86±1.96. Mean±SD Q-angle in patients with normal and abnormal alignment was 14.76±1.54 and 14.63±1.9 respectively. There is statistically no significant correlation between BMI and VAS score (r=0.054, p=0.344). Means±SD of mLDFA, mMPTA, mTFA, aTFA, and JOA were 88.86±2.73, 84.96±3.00, 5.96±4.01, 4.55±3.67, and 2.37±1.88 respectively. JOA and mTFA had statistically significant weak positive correlation with VAS (knee pain) score, (r=0.281) (p=0.000) and (r=0.236) (p=0.000) respectively. The rest of the angles were not had statistically significant correlation with VAS score. The mTFA had statistically significant weak positive correlation with all the angles. We found that Frontal plane tibiofemoral alignment correlates with knee pain in patients with early OA. Conclusions: The mTFA may be considered one important criterion in designing treatment and planning surgery for patients with primary osteoarthritis. The Q angle acts as a good alternative clinical tool in assessing frontal plane alignment. BMI was not correlating with knee pain (VAS score)

Patchy layered structure of tropical troposphere as seen by Indian MST radar

The MST radar observations at Gadanki (13.47° N, 79.18° E) show, almost every day throughout the year, stratified layers of intense reflectivity near the tropopause level (17 km) and also at a couple of levels between 4 km and 10 km. Highest individual reflectivity values occur near 17 km, but they occur for a short while. The region between 11 km and 15 km shows the lowest values of reflectivity alongwith vertical downward motion almost on all days of the year. High values of reflectivity are attributed to the existence of visible or sub-visible clouds; the layered structure of clouds is attributed to inertio-gravity waves with vertical wavelength of 2-3 km. It is suggested that each high reflectivity layer consists mainly of thin sheets and patches of visible and sub-visible cloud material. Hydrometeors inside the cloud material go up and down due to gravity, precipitation-loading, Brunt-Vaisala oscillations, and Kelvin-Helmholtz waves. In these small-scale motions, thin air sheets and patches get formed with sharp temperature and humidity discontinuities through contact cooling, melting, evaporation, condensation and freezing. Also, melting and freezing at low temperatures generate electrical charges in these thin sheets and patches. These thin sheets and patches have vertical dimensions ranging from a few centimetres to several metres and horizontal dimensions of the order of 1km. These thin sheets and patches have corresponding vertical and horizontal discontinuities and sharp gradients in refractive index for the MST radar beam. These show up as regions of high values of reflectivity

Pharma Image Information Extraction Using Image Processing

In order to obtain better recovery and avoid any side effects it is critical that the patient should take correct medicine for the illness they are suffering with. It is important that the medicine that is taken should produce the maximum benefit for the person. This is the very important aspect of medication but we are finding many cases wherein the erroneous information about the drug might create bad affects on the people and tend to extend many problems instead of reducing the ailment. The main reason for this, is lack of information about the drug to the patient and some being illiterate or mind belief on the drugs. So as to overcome this issue Pharma Image Information Extraction using Image Processing is a medication application which helps you to view the medicine based on the symptoms to which the medicine is to be used at anytime, anywhere through your phone. It helps you to get the information of the medicine by just sitting at your house and taking the picture of the medicine. This paper mainly focuses on extracting the text on the tablet strip and offer correct information about the tablet and vice versa which helps the illiterates not to get cheated with the dubious medicines mapping to the symptoms he/she is suffering with

Optical power limiting in the femtosecond regime by silver nanoparticle–embedded polymer film

A simple methodology is developed for the fabrication of freestanding polymer films with embedded silver nanoparticles grown in situ. Strong nonlinear absorption, positive nonlinear refraction, and efficient optical limiting in the femtosecond regime are demonstrated with these films. Additional investigations with supported films as well as parallel studies in the nanosecond regime are also presented. The freestanding nature of the films is not only of potential interest from the application perspective but also facilitates the unambiguous determination of the nonlinear coefficients of the metal nanoparticles embedded in polymer matrix without complications arising due to the contributions from the substrate

Thin films of metal-organic compounds and metal nanoparticle-embedded polymers for nonlinear optical applications

Thin films based on two very different metal-organic systems are developed and some nonlinear optical applications are explored. A family of zinc complexes which form perfectly polar assemblies in their crystalline state are found to organize as uniaxially oriented crystallites in vapor deposited thin films on glass substrate. Optical second harmonic generation from these films is investigated. A simple protocol is developed for the \textit{in-situ} fabrication of highly monodisperse silver nanoparticles in a polymer film matrix. The methodology can be used to produce free-standing films. Optical limiting capability of the nanoparticle-embedded polymer film is demonstrated
