Rain attenuation poses a significant challenge for high-throughput communication systems. In response, this paper introduces an artificial intelligence (AI) model designed for predicting and mitigating rain-induced impairments in high-throughput satellite (HTS) to land channels. The model is based on three AI algorithms developed using 3D antenna design to characterize, analyze, and mitigate rain-induced attenuation, optimizing channel quality specifically in the United Arab Emirates (UAE). The study evaluates various parameters, including rain-specific attenuation, effective slant path through rain, rain-induced attenuation, signal carrier-to-noise ratio, and symbol error rate, for five conventional modulation schemes: Quadrature Phase-Shift Keying (QPSK), 8-Phase Shift Keying (8-PSK), 16-Quadrature …

Thermal Phonon Fluctuations And Stability Of The Magnetic Dual Chiral Density Wave Phase In Dense Qcd, Efrain J. Ferrer, William Gyory, Vivian De La Incera Feb 2024

Thermal Phonon Fluctuations And Stability Of The Magnetic Dual Chiral Density Wave Phase In Dense Qcd, Efrain J. Ferrer, William Gyory, Vivian De La Incera

Physics & Astronomy Faculty Publications

We study the stability against thermal phonon fluctuations of the magnetic dual chiral density wave (MDCDW) phase, an inhomogeneous phase arising in cold, dense QCD in a magnetic field. Following a recent study that demonstrated the absence of the Landau-Peierls (LP) instability from this phase, we calculate the (threshold) temperature at which the phonon fluctuations wash out the long-range order over a range of magnetic fields and densities relevant to astrophysical applications. Using a high-order Ginzburg-Landau expansion, we find that the threshold temperature is very near the critical temperature for fields of order 10 18     G and still a sizable …

What Diameter? What Height? Influence Of Measures Of Average Tree Size On Area-Based Allometric Volume Relationships, Yilin Wang, John A. Kershaw, Mark J. Ducey, Yuan Sun, James B. Mccarter Feb 2024

What Diameter? What Height? Influence Of Measures Of Average Tree Size On Area-Based Allometric Volume Relationships, Yilin Wang, John A. Kershaw, Mark J. Ducey, Yuan Sun, James B. Mccarter

Faculty Publications

Volume is an important attribute used in many forest management decisions. Data from 83 fixed-area plots located in central New Brunswick, Canada, are used to examine how different measures of stand-level diameter and height influence volume prediction using a stand-level variant of Honer's (1967) volume equation. When density was included in the models (Volume=f(Diameter,Height,Density)) choice of diameter measure was more important than choice of height measure. When density was not included (Volume=f(Diameter,Height)), the opposite was true. For models with density included, moment-based estimators of stand diameter and height performed better than all other measures. For models without density, largest tree …

Rates Of Diagenesis Of Tropical Insectivorous Bat Guano Accumulations: Implications For Potential Paleoenvironmental Reconstruction, Donald A. Mcfarlane, Joyce Lundberg Feb 2024

Rates Of Diagenesis Of Tropical Insectivorous Bat Guano Accumulations: Implications For Potential Paleoenvironmental Reconstruction, Donald A. Mcfarlane, Joyce Lundberg

International Journal of Speleology

Cave guano deposits are increasingly being recognized as valuable repositories of paleo-climatic and paleo-environmental information. However, that value is constrained by rates of guano decomposition, and these rates have not been previously well-studied. Here we show that field and laboratory studies of deep insectivorous bat guano sequences in the caves of Borneo demonstrate the extreme dependence of decomposition rate on guano water content. Under tropical conditions, moist guanos exhibit decomposition coefficients (k) values of ~ 0.01, implying the loss of most of the organic content on decadal timescales. Under similar temperatures but drier conditions, k values drop to …

Revolutionizing Denture Excellence: An Invigorating In-Vitro Exploration Of Organic Products In Prosthetic Rehabilitation, Nighila Ravindran, Sneha Joseph, Aswani Surya K

Annual Research Symposium

The denture base comes into contact with diverse substances in the oral cavity, acting as a reservoir for microorganisms like corynebacterium, streptococcus, lactobacillus, and candida. This colonization elevates the risk of complications such as denture stomatitis and candidiasis. Commercial denture cleaners have explored the use of natural ingredients, less commonly employed but offering various advantages. These ingredients aim to mitigate the potential issues associated with microbial colonization on denture surfaces, contributing to improved oral hygiene for denture wearers. The exploration of natural elements reflects a nuanced approach to denture care, considering both efficacy and less conventional alternatives.

Assessment Of Emotional Intelligence Among Students In Dental College, Gowri Nandana S Final Year Student, Sudeep C. B Professor And Head Of The Department Of Public Health Dentistry Feb 2024

Assessment Of Emotional Intelligence Among Students In Dental College, Gowri Nandana S Final Year Student, Sudeep C. B Professor And Head Of The Department Of Public Health Dentistry

Annual Research Symposium

Over an extended period, the examination of intelligence predominantly centered on the adaptive deployment of cognitive abilities. In more recent times, scholars such as Gardner (1983) and Sternberg (1988) have proposed comprehensive frameworks for comprehending intelligence. Pioneering the concept of "emotional intelligence," Salovey and Mayer (1990) posited that emotional intelligence encompasses three distinct categories of adaptive capabilities: the evaluation and expression of emotions, the regulation of emotions, and the utilization of emotions in problem-solving. The objective is to evaluate emotional intelligence among dental students across various educational institutions.

Isolation And Culture Of Epichloё Sp. For Re-Infection Of Endophyte-Free Southeastern Wildrye (Elymus Glabriflorus), B. J. Haile, J. I. Morrison

IGC Proceedings (1977-2023)

Mutualistic relationships between endophytic fungi and grasses have shown to improve the hardiness of the host. This relationship is common in grasses, including native cool-season grasses that are important in both forage and grassland ecosystems. Elymus genus members, such as Canada wildrye (CAWR), commonly host the endophytic fungi, Epichloё, while southeastern wildrye (SEWR) may not. In this study, seed of ten Elymus accessions and seed and leaves from local SEWR were assessed for endophyte infection. Infection status was confirmed via seed squash and leaf peel techniques and assessed using microscopy. Seed of one SEWR and nine CAWR accessions were assessed …

Virtual Fencing Predictable For Cattle? A Simple Method To Test Whether And How Fast Cattle Can Learn The Association Between Acoustic Signal And Electric Pulse, D. Hamidi, M. Komainda, N. Grinnell, L. Wilms, F. Reisch, J. Horn, M. Hamidi, J. Isselstein Feb 2024

Virtual Fencing Predictable For Cattle? A Simple Method To Test Whether And How Fast Cattle Can Learn The Association Between Acoustic Signal And Electric Pulse, D. Hamidi, M. Komainda, N. Grinnell, L. Wilms, F. Reisch, J. Horn, M. Hamidi, J. Isselstein

IGC Proceedings (1977-2023)

Virtual fencing (VF) offers promising future prospects for improved grazing management as it has the potential to simplify fencing. VF lines are easily drawn and shifted via GPS coordinates. A VF collar emits an acoustic signal when the animal approaches the VF line. The signal stops immediately when the animal turns around. If the animal continues to move towards the VF line, a short electric pulse is emitted. A teaching and an operating mode are provided by the VF collars. The animals automatically change mode when they respond correctly to 20 consecutive acoustic signals without receiving an electric pulse. A …

More Than A Fencing System? Testing The Validity Of Virtual Fencing Collars For Animal Monitoring On Pasture, D. Hamidi, M. Komainda, N. Grinnell, F. Reisch, J. Horn, M. Hamidi, I. Traulsen, J. Isselstein Feb 2024

More Than A Fencing System? Testing The Validity Of Virtual Fencing Collars For Animal Monitoring On Pasture, D. Hamidi, M. Komainda, N. Grinnell, F. Reisch, J. Horn, M. Hamidi, I. Traulsen, J. Isselstein

IGC Proceedings (1977-2023)

High labour requirements for fencing and animal monitoring appear to be general obstacles for the wider use of pastureland for grazing livestock. Virtual fencing (VF) enables a less laborious pasture management. Fence lines can be easily drawn and moved using GPS data. The advantages of VF for reducing the labour inherent to controlled grazing management are obvious. Potential additional animal monitoring opportunities arising from such a VF system that uses real-time GPS data have not yet been studied. Lying is seen as an indicator for assessing comfort or restlessness of cattle. Therefore, we focus on lying behavior in this evaluation. …
