Final Report for GNC03-017

The evaluation of three ground floor management systems for organic apple orchards suggests that the Swiss Sandwich System (SSS) is the most promising for Michigan and other states with similar climate. Mulching (alfalfa hay) increases significantly the amount of available nitrogen and organic matter in the soil compared with the other two systems. Flaming and SSS release the same. Mulching actually releases too much nitrogen risking leaching problems. Root dynamics were affected from the treatments under evaluation behaving differently depending on time of the year, position related to the tree, and depth in the soil profile. The systems affect the soil food web with mulching and SSS creating a comparable environment while flame has the lowest population numbers.
A study of capillary forces as a gripping principle

Purpose – This work aimed at studying the use of capillary forces as a gripping principle in the handling of sub‐millimetric sized components. The goal was to present the results as design rules of so‐called capillary grippers.Design/methodology/approach – Each parameter (surrounding environment, materials, volume of liquid, separation distance, gripper geometry and gripper size, relative orientation of the gripper with respect to the component) has been quantified, either numerically or experimentally. In some validation cases, both means have been used.Findings – The capillary forces can be modified between a maximum Fmax and a minimum Fmin so that a component with any mass m between Fmin/g and Fmax/g can be picked up and released.Research limitations/implications – By comparison with some existing capillary grippers prototypes, this work is only a theoretical and experimental study. Nevertheless, its originality lies in the exhaustive study and quantification of all parameters so that most of the capil.

Optical Time Division Multiplexing (OTDM) and Hybrid WDM/OTDM PON Performance Investigation

Every day, the need for high speed reliable data transmission increases more and more. One important option is the passive optical networks which use the optical fiber and provides high data rates and long distance. This work investigates the performance of a four users Optical Time Division Multiplexing OTDM over different length of single mode fibers SMF for different bit rates. The effect of utilizing Eribium Dopped Fiber amplifiers EDFAs was investigated for mitigating effect of performance degradations due to attenuation. In order to increase capacity of the system, A hybrid four Wavelength Division Multiplexing WDM and four OTDM system was proposed Dispersion Compensating Fiber DCF was used for reducing the effect of dispersion distortion. A post dispersion compensation was applied to a four users OTDM each with bite rate of 10 and 40 Gbps in terms of data capacity per Optical Network Unit ONU. A bit rate of 160 Gbps was obtained from the work with an BER of 10 over length of 352.89km. The simulation was implemented using optisystem 7 and matlab R2011a.
Experimental Investigations of Masonry Columns Strengthened by SGFRP under Eccentric Loads

5 masonry columns were strengthened by Sprayed Glass Fiber Reinforced Polymer (SGFRP) in this paper, and a research of the seismic behavior of them tested by eccentric loading experiment was presented. The failure modes of the strengthened masonry columns were illustrated and strengthening effects of them were discussed. The results showed that the bearing capacity of the reinforced columns increased greatly, and the ductility of them also improved significantly. Comparing the strengthening effects of the columns when the thickness of SGFRP and the number of glass fiber are different, some reasonable reinforce suggestions are proposed.
CSCI424/CSCI924 - Assignment 3 - Deep Neural Networks

Deep Neural Networks (DNNs) are architectures of multiple layers of perceptrons, designed to solve complex learning problems. However, DNNs face challenges in terms of training and generalisation. Traditional DNNs with large numbers of interconnections can overfit, and require different training techniques to improve generalization. Pretraining of connection weights and new flavours of neural networks aim to overcome these issues. Convolutional Neural Networks, in particular, are designed to process images by minimizing trainable weights and providing strong generalization abilities. These networks show good promise in complex learning tasks in multiple domains.
DETECTION OF HUMAN EMOTIONS IN AN IMAGE USING CNN

---------------------------------------------------------------------***------------------------------------------------------------------- Abstract - Emotions possessed by humans can be recognized and has a vast scope of study in the computer vision industry. Emotions can be recognized by various means. Facial expression, body language, voice level, etc. can be used for detection. In this paper we used a model to recognize emotion by facial expressions which play very important role in human communication. Since human face is the richest source of emotion, in which conversations depend much on emotions. There are numerous human-machine interactions.
3D PRINTED ELECTRIC MOTORS AS A STEP TOWARDS SELF-REPLICATING MACHINES

This research addresses the application of 3D printing technologies in innovative electrical machinery. To date, there is a lack of fabricated devices with electromechanical functionality for parts entirely manufactured using only Additive Manufacturing (AM) technologies. This study provides a new and different approach to create a fully 3D printed electric motors, with a focus on an additively manufactured iron core, winding, insulation, and permanent magnet. We investigate how to develop 3D printed motor with multi-material and multi-technique without using embedding devices. Several prototypes of radial and axial flux DC electric motors were fabricated and tested. Their functionality indicated the potential of achieving 3D-printed motor using inexpensive, commercially available equipment. A good plan application is to use the 3D printed motor as the core component of a self-replicating machine. Suppose such a machine was deployed on the Moon. It could be a robotic system that uses lunar materials to replicate itself and, eventually, fabricate a broad range of future space assets.
Stressors, Manifestations and Course of COVID-19 Related Distress Among Nurses and Midwives in Tasmania

Introduction The deleterious effects relating to the COVID-19 pandemic on the mental health of healthcare workers has now been widely established. Understanding how COVID-19 affects their work and life is complex and multidimensional. This longitudinal study describes the critical stressors and how they manifest within both the work and larger social environment for nurses and midwives in Tasmania, Australia. Methods This longitudinal, descriptive survey explores the trajectory of the psychological health of Tasmanian public sector nurses and midwives during the COIVD-19 pandemic. The survey was distributed at 3 timepoints over a 12-month period and consisted of a battery of psychological tests which included the Patient Health Questionnaire, General Anxiety Disorder, Insomnia Severity Index, and the Impact of Events Scale-Revised, together with free text comments. Analysis The associations between outcome and predictor variables were assessed using mixed effects linear regression and linear mixed model analyses. Free text comments were themed. Results High levels of stress and mental exhaustion were attributed to threatened workplace team culture; compromised quality of patient care; the impact on family, home, financial and economic domains; lack of clear communication; issues surrounding personal protective equipment; and female gender. Study data show younger nurses and midwives suffered higher levels of stress and mental exhaustion than older. Conclusion This study highlights the need for stable and functional relationships at home and at work for nurses and midwives. Factors which will help preserve the mental health of nurses and midwives include strong workplace culture with ongoing processes to monitor organisational burnout; building resilience, particularly among younger nurses and midwives; protection of healthcare worker safety; clear communication processes and supporting stable and functional relationships at home. The health service has an imperative to ensure optimum service delivery by safeguarding staff, despite the inevitable health stress imposed by the nature of the work.
Statistical analysis and stochastic simulation of ground-motion data

The time variations of the root-mean-square accelerations, the autocorrelation functions, and the power spectral density functions of 12 strong-motion earthquake accelerograms are analyzed. The results indicate that: (i) strong-motion accelerograms of sufficiently long duration are stationary in the rms sense, (ii) the stationary rms acceleration is a good measurement of earthquake intensity, and (iii) the autocorrelation and power spectral density functions of strong-motion accelerograms resemble those of a narrowband process. Based upon these results, a method of determining the transfer characteristics of a site is introduced. A procedure for generating a filtered, gaussian stationary process to simulate ground motions is developed, and two applications of this simulation procedure illustrate its significance.
Study on the traveling magnetic field water purifier

The article discusses a new technology for Uzbekistan of purifying drinking water from mechanical particles. This is achieved due to the generated traveling magnetic field of the electric winding wound on the metal cylinder. An analysis of the resulting mechanical attraction forces in the space of a cylindrical purifier is given. Mathematical expressions are given to calculate these forces. The analysis of the obtained graphs of temporal and spatial characteristics is presented. The values of currents allow effectively implementing the process of water purification from mechanical impurities is determined.
Experimental evidence for nonlucky electron model effect in 0.15-/spl mu/m NMOSFETs

It is shown that in 0.15-/spl mu/m NMOSFETs the device lifetime under channel hot-carrier (CHC) stress is lower than that under drain avalanche hot-carrier (DAHC) stress and therefore the hot-carrier stress-induced device degradation in 0.15-/spl mu/m NMOSFETs cannot be explained in the framework of the lucky electron model (LEM). Our investigation suggests that such a "non-LEM effect" may be due to increased interface state generation by the movement of the maximum impact ionization site from the lightly doped drain (LDD) diffusion region to the boundary of the bulk and LDD region beneath the gate oxide. This paper provides experimental evidence for the non-LEM effect by comparing the degradation characteristics and the maximum impact ionization sites as a function of gate oxide thickness and gate length.
Dynamics of GB-speckles with a small number of scatterers

A method for generating dynamic GB-speckles, formed during diffraction of focused Gaussian beams by moving virtual rough surfaces, obtained for two nucleotide sequences (the ompA genes of the Chlamydia psittaci GR9 and AMK-16 strains), is proposed. The statistical characteristics of the 1st- and 2nd-order statistics of GB-speckles, formed at a small number of scattering events, are studied. The difference in the manifestation of the Doppler effect in the dynamics of GB-speckles and for speckles, formed with a small number of scatterers, produced by light diffraction on physically-existing rough surfaces and in scattering micro-streams is revealed. The problems of interference of dynamic GB-speckles are considered. A new technique for detecting individual single nucleotide polymorphism in nucleotide sequences using the interference of dynamic GB-speckles is proposed.

Fuel cell is one of alternative method to replace fossil fuel energy. The important component of fuel cell is a membrane that used for separating cathode and anode also as a proton conductor. The purpose of this research is to produce polymer electrolyte membrane from poly (eugenol sulfonate) (PES) as polymer matrix, characterize the resulting membrane analysis using ionic properties analysis by calculating ionic conductivity using impedance spectroscopy, ion exchange capacity (IEC), solvent absorption analysis by calculating water uptake and methanol permeability, and studying mechanism Proton transport that occurs on the membrane. This research was initiated by making polymer of PES, and then fabrication and characterization of electrolytic polymer membrane. The formed membrane has an optimal proton conductivity of 0.00095 S.cm-1 with PES composition of 22% (wt).

Sea surface temperatures in the South China Sea as a natural thermostat to the rainfall over Borneo: preliminary results

Community Climate System Model version 4 (CCSM4) simulated warmer sea surface temperatures (SSTs) in the South China Sea (SCS) for the mid-Holocene scenario compared to the pre-Industrial. Previous sensitivity experiments using the atmospheric component of the CCSM4, the Community Atmospheric Model version 4 (CAM4), showed that warmer SSTs in the SCS suppresses rainfall over Borneo, which is in-contrary to the effect of the stronger insolation over the island. In this study, we show that warmer SSTs in the SCS, as simulated in the CCSM4, is responding to a weaker low-level wind impacted by the stronger convectional rainfall over Borneo due to stronger insolation. These results suggest that warmer SSTs in the SCS might act as a negative feedback which damps the effect of the stronger insolation on rainfall changes over Borneo.
Modelling of Fluidity during Hot Compaction of Ti-B System Synthesized Mass

Developing the scientific basis for making new materials with pre-planned, physical and mechanical properties by SHS (self-propagating high temperature synthesis)-compaction is a fundamental problem of modern metallurgy, which can be solved by imaginative modeling of the structural-phase state of materials. Among the many methods of obtaining metal-ceramic tiles, the ease of process management, cheapness, ecological cleanliness and the possibility of obtaining high-quality products are significantly distinguished by the innovative SHS electrrical rolling process developed at the F. Tavadze Institute of Metallurgy and Materials Science, which, by maintaining the equilibrium velocities of the rolling and combustion fronts, ensures hot deformation of the hot viscous plastic mass in the deformation core under conditions of continuous compensation of heat losses Namicheishvili, 2016 [1] and Aslamazashvili, 2017 [2].
Two-proton radioactivity of ground and excited states within a unified fission model

A unified fission model is extended to study two-proton radioactivity of the ground states of nuclei, and a good agreement between the experimental and calculated half-lives is found. The two-proton radioactivity half-lives of the ground states of some probable candidates are predicted within this model by inputting the released energies taken from the AME2020 table. It is shown that the predictive accuracy of the half-lives is comparable to those of other models. Then, two-proton radioactivity of the excited states of 14O, 17,18Ne, 22Mg, 29S, and 94Ag is discussed within the unified fission model and two analytical formulas. It is found that the experimental half-lives of the excited states are reproduced better within the unified fission model. Furthermore, the two formulas are not suitable for the study of two-proton radioactivity of excited states because their physical appearance deviates from the mechanism of quantum tunneling, and the parameters involved are obtained without including experimental data from the excited states.
Watt-level SHG in undoped high step-index PPLN ridge waveguides

Nonlinear quadratic waveguides are key components to obtain efficient frequency conversion. The performances of highly multimode periodically poled lithium niobate (PPLN) ridge waveguides for high power CW SHG are presented. We report generation of 1 W of second harmonic on the fundamental guided mode with a conversion efficiency of 56% at telecom wavelengths. A stable nonlinear process is obtained despite use of an undoped congruent LiNbO3 crystal. The input damage threshold of the ridge waveguide is found to set the maximum usable power. © 2021 Optical Society of America
Computer Evaluation Of Musical Timbre Transfer On Drum Tracks

Musical timbre transfer is the task of re-rendering the musical content of a given source using the rendering style of a target sound, this task is sometimes also called interpretation. The source keeps its musical content, e.g., pitch, microtiming, orchestration, and syncopation. We speciﬁcally focus on the task of transferring the style of percussive patterns extracted from polyphonic audio using a MelGAN-VC model (Pasini, 2019) by training acoustic properties for each genre. Evaluating audio style transfer is challenging and typically requires user studies. We propose an analytical methodology based on supervised and unsupervised learning including visualization for evaluating musical timbre transfer that can be used instead of, or in addition to, user studies. The proposed methodology is used to evaluate the MelGAN-VC model for musical timbre transfer of drum tracks.
Performance Assessment of Decentralized Controllers

Abstract Abstract Minimum variance (MV) benchmark is useful for identifying variance reduction opportunities in industrial control systems. During the past two decades, MV benchmarks for single-input single-output (SISO) and multi-input multi-output (MIMO) systems have been proposed. These MV benchmarks do not account for the structure of the decentralized or multi-loop controllers, which are used almost exclusively for regulation purposes in process industries. Due to this drawback, the available MV benchmarks can lead to incorrect conclusions regarding the performance of decentralized controllers. This paper aims to fill this gap. For performance assessment of decentralized controllers on a loop-by-loop basis, we present a simple modification of the available MV benchmark for SISO systems. For simultaneous performance assessment of all loops, we present a method for computing a tight lower bound on the achievable output variance. In the latter approach, the non-convexity of the resulting optimization problem is handled using sums of squares programming. The usefulness of the proposed benchmarks is evaluated using examples drawn from the literature.
Evaluation of Biokinetic Parameters and Biological Treatability of Amman Slaughterhouse Wastewater Using Sequencing Batch Reactor (SBR)

A bench scale sequencing batch reactor with a total volume of 10L was used to study the treatability of Amman slaughterhouse wastewater and to investigate the effect of both cycle time and phase time on the performance of the sequencing batch reactor (SBR). Results showed that SBR operated with 8 hrs cycle time has achieved the best COD percentage removal of 98.7%. The operational mode resulting in the best treatment outcome was the 40% fill to react ratio which achieved COD removal between 85.3% and 97.3%. The performance of SBR in removing nutrients showed good ON, and P removals of 95% and 81%; respectively. The biokinetic coefficients of Amman slaughterhouse wastewater were determined using four bench scale batch reactors. Values of biokinetic constants obtained were Ks = 229.12mg/L, Y = 0.483 g/g, µmax = 0.618 d-1, and kd = 0.129 d-1; which compare reasonably well with values reported in literature.
Investigation of laser and thermal sintering processes of silver nanoparticles agglomerates synthesized by spark discharge

Changes in the shape and size of silver nanoparticles (NPs) during their laser and thermal sintering have been studied experimentally and theoretically. Aerosol silver NPs forming dendrid-like agglomerates 180 nm in size were synthesized by spark discharge and exposed to laser radiation and high temperature of 750 °C. The shape and size of the NPs were investigated depending on the power of the laser radiation and the temperature of the gas. It is estimated that, at a power density of laser radiation of the order of 103-104 W/cm2, the formation of spherical NPs with an average size of 140 nm is expected. Such particles turn out to be similar to NPs thermally heated in a gas flow at 750 °C for 6 seconds.
