Observed Seasonal Variation Of Wave Power From Moored Buoy Measurements - A Case Study On The East Coast of India
Abstract: The wave climate in Indian waters is strongly influenced by the seasonal variation. Accurate wave height assessment is crucial for wave power computation which is proportional to square of the significant wave height. Any error in wave height is magnified in the wave power estimation. Wave models tend to predict medium range wave activity to a desired degree. Insufficient wind, bathymetry and grid resolutions, model physics parameterizations also account for …

Speech Perception in Geriatric Population
Abstract: Ageing is one of the characteristic features seen in organisms of the animal kingdom; after birth via ageing first the development and maturation take place which when progresses with time results in degeneration and ultimately ends with the end of the life cycle of the organism. As humans are no different; our maturation phase starts right after birth, which results in complete maturation by the time humans reach adulthood [1]. …

Response of Cultivars and Picking Dates on Storability of Karonda (Carissa Carandas L.) Jelly
Abstract: Karonda jelly was prepared from cultivars viz ‘Pant Manohar’, ‘Pant Sudarshan’ and ‘Pant Suvarna’ at picking dates of 40, 60 and 80 days after fruit set. The shelf stability of the jelly samples were evaluated at ambient temperature for a period of nine months. The ‘Pant Suvarna’ jelly exhibited maximum moisture, total soluble solids (TSS), reducing sugar, non-reducing sugar, total sugar, non-enzymatic browning and pectin content. Among picking dates, the …

What if the "Big Bang" was not the Beginning Point of our Observable Universe?
Abstract: The Big Bounce theory envisions the Big Bang as the start of a period of expansion followed by a period of contraction. According to this viewpoint, there was a Big Crunch (another singularity) followed by a Big Bang, or, more simply, a Big Bounce. This implies that we could be at any point in an infinite series of universes, or that the current universe is the very first interaction. But …

Mathematical Approaches to Nonlinear Oscillatory Systems with Damping: Exact and Approximate Solutions
Abstract: The study of nonlinear oscillatory systems with damping is a key area of research in applied mathematics, particularly in the context of dynamical systems, stability analysis, and bifurcation theory. These systems, described by second-order nonlinear differential equations, exhibit a rich variety of behaviors, including periodic, quasi-periodic, and chaotic motions. The introduction of damping—representing energy dissipation—adds a layer of complexity, making the analytical and numerical solution of such systems a challenging …

FPGA-based Multichannel Digital Duty-Cycle Modulation and Application to Simultaneous Generation of Analog Signals
Abstract: The DCM (duty-cycle modulation) is used in industrial electronics as a special technique for producing switching time-varying periodic waves, with variable pulse width and modulation period. As an implication, unlike the fixed period of a PWM wave, the cyclic ratio of a DCM signal changes as a function of the modulating input according to a known function. However, most existing research works related to DCM-based instrumentation systems, are limited to …
