Binary, bodies, beyond: an account of TGNC embodiment
Creators: name: Boxall, Lucinda
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Embodiment, the experience of bodily existence and its fundamental influence over our perceptions of ourselves and others, is a bedrock of both anthropological literature and trans studies. However, aside from a handful of works (e.g., Seamont, 2019 and Malatino, 2018), the two fields have remained largely separate in their treatment of trans intersubjectivity, body modification and the limits of language. In this thesis, I seek to bridge this separation. Drawing from a 4-month period of fieldwork with five trans gender non-conforming (TGNC) individuals, the thesis demonstrates the beauty and variety of embodiment enacted by not-cis individuals. To do so the thesis is structured into five accounts, each of which encapsulate one individual and the everyday nuances of being in their body. Woven within these accounts are extensive quotations and self-taken photographs, intended to create an authentic multimodal representation of the individual. Each individual is presented in a single piece of writing, with accounts placed next to one another to complement and contrast individual understandings and experiences of embodiment. Dominant themes including the limitations of language, desire for and rejection of body modification, and intersubjective embodiment as fluid, ever-changing and ongoing, are conveyed at an individual level with external literature and theory referenced as appropriate. The conclusion weaves these threads together to explore what they may mean at a more collective level, emphasizing the need for trans and gender non-conforming voices in anthropology.

description: We present a method to derive the relative pointing offsets for SPIRE Fourier-Transform Spectrometer (FTS) solar system object (SSO) calibration targets, which were observed regularly throughout the Herschel mission. We construct ratios of the spectra for all observations of a given source with respect to a reference. The reference observation is selected iteratively to be the one with the highest observed continuum. Assuming that any pointing offset leads to an overall shift of the continuum level, then these ratios represent the relative flux loss due to mispointing. The mispointing effects are more pronounced for a smaller beam, so we consider only the FTS short wavelength array (SSW, 958-1546 GHz) to derive a pointing correction. We obtain the relative pointing offset by comparing the ratio to a grid of expected losses for a model source at different distances from the centre of the beam, under the assumption that the SSW FTS beam can be well approximated by a Gaussian. In order to avoid dependency on the point source flux conversion, which uses a particular observation of Uranus, we use extended source flux calibrated spectra to construct the ratios for the SSOs. In order to account for continuum variability, due to the changing distance from the Herschel telescope, the SSO ratios are normalised by the expected model ratios for the corresponding observing epoch. We confirm the accuracy of the derived pointing offset by comparing the results with a number of control observations, where the actual pointing of Herschel is known with good precision. Using the method we derived pointing offsets for repeated observations of Uranus (including observations centred on off-axis detectors), Neptune, Ceres and NGC7027. The results are used to validate and improve the point-source flux calibration of the FTS.

description: Experimental and numerical studies were presented in this paper to investigate the fire behavior of high strength steel (Q690 and Q960) shear and T-stub connections. The load–displacement curves, failure modes, and load capacities at elevated temperatures were obtained from the experiment. Finite element models were established by ABAQUS software and validated by the test results. The test capacities of shear connections were compared with those predicted by EC3, AISC 360-16, and GB50017, while the test capacities of T-stubs were compared with that predicted by EC3. Results show that the failure temperature from brittle failure to ductile failure is approximately 500 ℃ for shear connections. The load capacity predicted by AISC 360-16 is accurate, while EC3 and GB50017-2017 are conservative for shear connections. The failure mode of T-stubs changed from the flange rupture to the bolt failure with yielding of the flange when the temperature was higher than 600 ℃. EC3 provides conservative results, while the modified equations accurately predict the first yield resistance for the T-stubs.

SINGLE-AGENT

description: This paper presents a methodology for routing aircraft at airports using a reinforcement learning approach. For this purpose, an aircraft was considered as an agent, while the airport in which the aircraft moves was considered as the environment. The airport was modeled as an undirected graph, composed of nodes (taxiway junctions) and segments (taxiways). The objective of the agent was to learn how to move from a departure node to a destination node by taking an optimal path. The optimal path within the scope of this study was assumed to be the shortest path, avoiding sharp turns (i.e., turns over 90 ) while limiting the number of turns along the way. The agent was trained using the Proximal Policy Optimization (PPO) algorithm by considering a single-agent environment. The trained agent was tested for different airports and over 400 different scenarios were designed by randomly selecting a departure node and a destination node. The results showed that the agent was able to find the optimal path with an average success rate of 98%. Then, the agent was tested in a multi-agent environment by considering multi-aircraft moving in the same airport. Similar results were obtained. The results obtained in this study have shown that reinforcement learning methods can provide a very good solution to the problem of aircraft routing at airports.

description: It is shown that external magnetic field or magnetization induces electric polarization of microscopic isolated magnetic/non-magnetic hybrid structures due to the spin-dependent electron redistribution and mutual capacity. The magnetoelectric effect can be very strong, for instance the change of electric polarization reaches $100$ $μC/m^{2}$ at a constant magnetic field of only $1.5$ Tesla in the case of $100$ $÷$ $10$ nanometer structures which tightly fill the space, composing a metamaterial. The effect does not require using exotic compounds. Based on the obtained results we suggest a number of recommendations for future experimental design.

description: We explore an asymmetric two-fermion Hubbard dimer to test the accuracy of the adiabatic approximation of time-dependent density functional theory in modelling time-resolved charge transfer. We show that the model shares essential features of a ground state long-range molecule in real-space, and by applying a resonant field we show that the model also reproduces essential traits of the CT dynamics. The simplicity of the model allows us to propagate with an "adiabatically-exact" approximation, i.e. one that uses the exact ground-state exchange-correlation functional, and compare with the exact propagation. This allows us to study the impact of the time-dependent charge-transfer step feature in the exact correlation potential of real molecules on the resulting dynamics. Tuning the parameters of the dimer allows a study both of charge-transfer between open-shell fragments and between closed-shell fragments. We find that the adiabatically-exact functional is unable to properly transfer charge, even in situations where the adiabatically-exact resonance frequency is remarkably close to the exact resonance, and we analyze why.

description: A novel steel connection with high axial and rotational ductility has been proposed with the objective to improve the performance of steel-framed buildings in fire. A series of sub-frame models with this ductile connection have been built using Abaqus to study the influence of the characteristics of the part of the connection between the fin-plate which connects to the beam web and face-plate which connects to the column face on the overall connection behaviour. Measures to improve the bolt pull-out failure mode of the connection have also been tested using the Abaqus models, including adding a strengthening plate to the face-plate and increasing the connection thickness.

description: An experimental investigation on material properties of double-sided stainless-clad bimetallic steel at elevated temperatures is reported in this paper. Totally, twenty-one tensile coupon specimens were extracted from a 3 mm thick bimetallic steel plate. The elevated temperature coupon tests were carried out applying the steady-state test method and the test temperatures were up to 900 °C. In addition, the impact of varying heat soak time on elevated temperature material properties was examined. Key material properties such as the elastic modulus, yield stress, ultimate strength and elongation after fracture were fully reported. The obtained elevated temperature reduction factors were compared with the predictions by various existing design rules, including AISC 360 and EN 1993-1-2 for carbon steel as well as AISC 370 and EN 1993-1-4 for stainless steel, to assess their applicability to this novel material. Overall, it is revealed that the existing design rules cannot accurately predict the stiffness and yield stress deteriorations of this new type of material at elevated temperatures.

description: Propagation of unsteady waves under the effect of a step point load on a square lattice of spring-connected masses is investigated. The problem is solved by two methods. Asymptotic solutions at large time intervals, which describe the behavior of long-wave perturbations, are derived analytically. The solution over the whole time interval for the waves of the entire spectral range is derived by the finite difference method. These solutions are compared, and their good agreement is shown.

OXYGEN PRODUCTION

description: In this work we address the possibility of oxygen production from the C02-emichedMartian atmosphere using plasma technology. A local production of oxygen from CO2 decomposition would reduce the logistics and costs of future missions, while providing a breathable environment for future human outposts, a source of rocket propellant and feedstock and base chemicals for building materials and fertilizers. A combination of experimental and modelling efforts is used to explore different plasma sources. Diversity of different plasma sources allows exploring different energy transfer pathways leading to CO2 dissociation, including direct electron impact processes, plasma chemistry mediated by vibrationally and electronically excited states, and thermally driven dissociation. Experimental results are validated against volume average OD self-consistent kinetic models accounting in detail for the very complex plasma chemistry. The model describes the kinetics of electrons and heavy species under Martian enviromnent in terms of pressure and temperature, relying on the Lisbon Kinetics (LoKI) simulation tool to solve the homogeneous two-term electron Boltzmann equation and the system of zerodimensional rate balance equations for the most relevant charged and neutral species. We analyze simulated electron energy distribution function (EEDF) for DC glow discharges, operated under continuous regime, at a pressure of 5 Tarr and discharge current of 50 mA, both for pure CO2 and 96%COz/2%Ar/2%N2 (synthetic Martian mixture). Moreover, we also demonstrate the versatility of plasmas to synthesize different compounds of interest to ISRU on Mars, including not only CO and 02 but also NO, products.

description: In this Letter, the 2-dimensional dense flow of polygonal particles on an incline with a flat frictional inferior boundary is analyzed by means of contact dynamics discrete element simulations, in order to develop boundary conditions for continuum models of dense granular flows. We show the evidence that the global slip phenomenon deviates significantly from simple sliding: a finite slip velocity is generally found for shear forces lower than the sliding threshold for particle-wall contacts. We determined simple scaling laws for the dependence of the slip velocity on shear rate, normal and shear stresses, and material parameters.The importance of a correct determination of the slip at the base of the incline, which is crucial for the calculation of flow rates, is discussed in relation to natural flows.

Fire safety engineering

description: In recent years, building construction industry in Algeria has started to include light gauge steel framed (LSF) wall systems as an alternative building solution especially in seismic regions. This is due to the advantages brought by the use of Cold Formed Section (CFS) that offers high durability, flexibility and strength to weight ratio. As these steel elements are slender, they are characterized with high shape factor, and the effect of the exposure to fire conducts to the possibility of the material properties degradation under high temperature. Thus causing different failure modes of stud members when subjected to a compression loading which could be leads to the collapse of the LSF panel. In this research work, different element models of single and double Lipped Channel (LC) stud that isolated from LSF panel, protected by plasterboard are produced using ANSYS APDL software. A parametric study is done, with the variation of type of cross-section for double stud including open and closed built-up sections. The main objective of this work is to study the influence of these sections on the behaviour of CFS stud LC members and the determination of the load capacity leading to understand the different buckling failure modes that could be occur under an axial compression loading at ambient and when exposed to fire ISO834. The results predict temperature profiles, progression of temperature, critical and ultimate load, critical temperatures and the failure mode.

description: We present a new method to probe atmospheric pressure on Earthlike planets using (O2-O2) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earthlike atmospheres, and may even be detectable in transit transmission with the James Webb Space Telescope (JWST). The absorption by dimers changes more rapidly with pressure and density than that of monomers, and can therefore provide additional information about atmospheric pressures. By comparing the absorption strengths of rotational and vibrational features to the absorption strengths of dimer features, we show that in some cases it may be possible to estimate the pressure at the reflecting surface of a planet. This method is demonstrated by using the O2 A band and the 1.06 $μ$m dimer feature, either in transmission or reflected spectra. It works best for planets around M dwarfs with atmospheric pressures between 0.1 and 10 bars, and for O2 volume mixing ratios above 50% of Earth's present day level. Furthermore, unlike observations of Rayleigh scattering, this method can be used at wavelengths longer than 0.6 $μ$m, and is therefore potentially applicable, although challenging, to near-term planet characterization missions such as JWST. We have also performed detectability studies for JWST transit transmission spectroscopy and find that the 1.06 $μ$m and 1.27 $μ$m dimer features could be detectable (SNR$>$3) for an Earth-analog orbiting an M5V star at a distance of 5 pc. The detection of these features could provide a constraint on the atmospheric pressure of an exoplanet, and serve as biosignatures for oxygenic photosynthesis. We have calculated the required signal-to-noise ratios (SNRs) to detect and characterize O2 monomer and dimer features in reflected spectra and find that SNRs greater than 10 at a spectral resolving power of R=100 would be required.

description: We investigate parse error detection methods under real-world conditions, outlining and testing different variables for evaluation and pointing to useful experimental practices. In particular, we focus on four different conversion methods, ten different training data sizes, two parsers, and three error detection methods. By comparing a set number of tokens across conditions, we measure error detection precision and revised labeled attachment scores to see the effect of each of the variables. We show the interactions between variables and the importance of accounting for parser choice and training data size (cf. initial parser quality). Importantly, we provide a framework for evaluating error detection and thus helping build large annotated corpora.

description: Given a Hopf algebra $H$ and a projection $H\to A$ to a Hopf subalgebra, we construct a Hopf algebra $r(H)$, called the partial dualization of $H$, with a projection to the Hopf algebra dual to $A$. This construction provides powerful techniques in the general setting of braided monoidal categories. The construction comprises in particular the reflections of generalized quantum groups, arxiv:1111.4673 . We prove a braided equivalence between the Yetter-Drinfel'd modules over a Hopf algebra and its partial dualization.

description: Purpose of Project: Family Educational Rights and Privacy Act violations present a severe risk to protecting student record privacy and the educational entity. This project aims to safeguard student record privacy in clinical nursing education. A comprehensive approach to FERPA training was created to improve the quality of an existing FERPA acknowledgment process at a large university. Methodology: This project is a quasi-experimental study with a one-group pre-test and post-test design. Comprehensive FERPA training was offered to a convenient sample of 135 faculty registered in the Orientation for Part-Time Faculty canvas course. A paired t-test was conducted via Microsoft Excel to test the null hypothesis of equal mean scores for the pre-test and post-test. Delta percentage in pre-test and post-test mean scores were analyzed to determine the change in knowledge attainment.Results: 32 of 35 participants completed the assignment. The paired t-test results showed there was no statistical significance between the average scores of the pre-test and post-test. The delta percentage change revealed a 16% increase in scores from the pre-test to the post-test, with 53% of the 32 participants increasing their post-test scores after the intervention.Implications for Practice: Upholding student privacy is integral to educational excellence. Non- compliance with the FERPA law can ruin educational entities' financial health and reputation. Healthcare professionals in teaching roles of all disciplines will benefit from comprehensive FERPA training.

description: Automated Rack Supported Warehouses (ARSW) combine the structural efficiency of metal construction with automated machines for handling the stored products. A fundamental distinction exists between traditional Steel Racks (SR) and ARSW, indeed ARSW are self-bearing rack structures committed to support, besides self-weight and weight of products, also environmental loads (i.e., wind, snow and seismic action) and all the other non-structural elements such as clads, equipment, etc. The peculiarity of these structures makes them a topic of great interest both for the scientific community and for the manufacturers of industrial racks. In the last years, a lot of research has been carried out to better understand the behaviour of these structures from the seismic point of view, while their behaviour in case of fire is still poorly known. Since the lack of regulations and technical references, this paper aims to provide a state of the art on ARSW structures in case of fire, with a discussion of the most critical aspects. For this reason, this paper provides first results about an advanced thermos-mechanical analysis of a case study, by considering a fire model that allows us to consider the vertical and horizontal propagation starting from a localized fire and providing a comparison between the capacity models that the regulations in case of fire propose for cold-formed steel members (CFS), which mainly made these structures.

description: The Fourier Transform Spectrometer (FTS) of the Spectral and Photometric Imaging REceiver (SPIRE) on board the ESA Herschel Space Observatory has two detector setting modes: (a) a nominal mode, which is optimized for observing moderately bright to faint astronomical targets, and (b) a bright-source mode recommended for sources significantly brighter than 500 Jy, within the SPIRE FTS bandwidth of 446.7-1544 GHz (or 194-671 microns in wavelength), which employs a reduced detector responsivity and out-of-phase analog signal amplifier/demodulator. We address in detail the calibration issues unique to the bright-source mode, describe the integration of the bright-mode data processing into the existing pipeline for the nominal mode, and show that the flux calibration accuracy of the bright-source mode is generally within 2% of that of the nominal mode, and that the bright-source mode is 3 to 4 times less sensitive than the nominal mode.

description: In his treatise on light, written in about 1225, Robert Grosseteste describes a cosmological model in which the Universe is created in a big-bang like explosion and subsequent condensation. He postulates that the fundamental coupling of light and matter gives rises to the material body of the entire cosmos. Expansion is arrested when matter reaches a minimum density and subsequent emission of light from the outer region leads to compression and rarefaction of the inner bodily mass so as to create nine celestial spheres, with an imperfect residual core. In this paper we reformulate the Latin description in terms of a modern mathematical model. The equations which describe the coupling of light and matter are solved numerically, subject to initial conditions and critical criteria consistent with the text. Formation of a universe with a non-infinite number of perfected spheres is extremely sensitive to the initial conditions, the intensity of the light and the transparency of these spheres. In this "medieval multiverse", only a small range of opacity and initial density profiles lead to a stable universe with nine perfected spheres. As in current cosmological thinking, the existence of Grosseteste's universe relies on a very special combination of fundamental parameters.

description: The characteristics of a superheated wall cooling through pulsed injection of a liquid jet was experimentally investigated under several conditions of the pulsed frequency at a constant flow rate. The liquid film behaviour was visualized, and the wall temperature distribution was measured simultaneously with a high-speed camera and an infrared camera. The longer non-injection period led to the suppression of the liquid film expansion. The effective use of the injected liquid for cooling through evaporation was achieved in the situation where the liquid was re-injected when the Fourier number ranged from 0.5 to 1.0.

description: We extend the notion of consecutive pattern avoidance to considering sums over all permutations where each term is a product of weights depending on each consecutive pattern of a fixed length. We study the problem of finding the asymptotics of these sums. Our technique is to extend the spectral method of Ehrenborg, Kitaev and Perry. When the weight depends on the descent pattern we show how to find the equation determining the spectrum. We give two length $4$ applications. First, we find the asymptotics of the number of permutations with no triple ascents and no triple descents. Second, we give the asymptotics of the number of permutations with no isolated ascents or descents. Our next result is a weighted pattern of length $3$ where the associated operator only has one non-zero eigenvalue. Using generating functions we show that the error term in the asymptotic expression is the smallest possible.

También se exploran visiones acerca de otros actores sociales (eg: asociaciones religiosas, sindicatos). Utilizando técnicas para la toma de decisiones participativa en el caso colombiano, observamos un posible cambo de rol o role shift hacia posiciones más activas de las empresas. La detección de diversas brechas o role gaps en la autopercepción empresarial y la percepción de otros actores con respecto a posibles capacidades aportadas a las políticas, nos permite discutir ajustes de roles y futuros desarrollos de investigación partiendo del marco utilizado, que es reproducible en otros contextos

description: HgBa$_{2}$CuO$_{4+δ}$ (Hg1201) has been shown to be a model cuprate for scattering, optical, and transport experiments, but angle-resolved photoemission spectroscopy (ARPES) data are still lacking owing to the absence of a charge-neutral cleavage plane. We report on progress in achieving the experimental conditions for which quasiparticles can be observed in the near-nodal region of the Fermi surface. The d-wave superconducting gap is measured and found to have a maximum of 39 meV. At low temperature, a kink is detected in the nodal dispersion at approximately 51 meV below the Fermi level, an energy that is different from other cuprates with comparable T$_c$. The superconducting gap, Fermi surface, and nodal band renormalization measured here provide a crucial momentum-space complement to other experimental probes.

description: Emission from the Herschel telescope is the dominant source of radiation for the majority of SPIRE Fourier transform spectrometer (FTS) observations, despite the exceptionally low emissivity of the primary and secondary mirrors. Accurate modelling and removal of the telescope contribution is, therefore, an important and challenging aspect of FTS calibration and data reduction pipeline. A dust-contaminated telescope model with time invariant mirror emissivity was adopted before the Herschel launch. However, measured FTS spectra show a clear evolution of the telescope contribution over the mission and strong need for a correction to the standard telescope model in order to reduce residual background (of up to 7 Jy) in the final data products. Systematic changes in observations of dark sky, taken over the course of the mission, provide a measure of the evolution between observed telescope emission and the telescope model. These dark sky observations have been used to derive a time dependent correction to the telescope emissivity that reduces the systematic error in the continuum of the final FTS spectra to ~0.35 Jy.

description: A test was designed and conducted to investigate the post-fire tensile behavior of the novel Hole-anchored Bolt (HB) bolted T-stub connection. The HB was anchored by the bolt hole with internal threads, for which the HB could be installed from one-side and is very suitable for the installation of the closed-section steel component. The full-period test method was used to consider the influence of load level and the fire temperature on the residual mechanical behavior of the HB bolted connection, including the failure mode, the failure stage, and the resistance. The diameter of the HB and the thickness of the bolt hole decided the failure mode of the connection. Fire temperature and the load level had little influence on the failure mode but had obvious impact on the failure stage of the connection. The T-stubs that not fail in fire still have good load carrying capacity after cooling down. The un-failed T-stubs could recover at least 87.1% of their yielding load and 80.9% of their ultimate load under post-fire circumstances.

description: In this study, the behaviour and resistances of cold-formed high-strength steel (CFHSS) square and rectangular hollow section (SHS and RHS) columns at elevated temperatures up to 1000°C were numerically investigated. A finite element model was developed and developed finite element model was validated with available test results of CFHSS SHS and RHS columns in terms of ultimate capacities, failure modes and load-deflection curves. After validation, a parametric study was performed by utilising stress-strain relationships of CFHSS at elevated temperatures developed based on prior research. A total of 280 CFHSS tubular columns of steel grade S700 were studied, covering a wide range of cross-sectional classes and member slenderness ratios. The applicability of current column design provisions in Eurocode 3 and AISI S100 Specification to the studied tubular columns at elevated temperatures was evaluated. Overall, it is shown that the codified design provisions may be used for the resistance predictions of the CFHSS tubular columns at elevated temperatures, while further improvement in terms of accuracy and consistency remains possible.

description: Topological superfluids are recently discovered quantum matters that host topologically protected gapless edge states known as Majorana fermions - exotic quantum particles that act as their own anti-particles and obey non-Abelian statistics. Their realizations are believed to lie at the heart of future technologies such as fault-tolerant quantum computation. To date, the most efficient scheme to create topological superfluids and Majorana fermions is based on the Sau-Lutchyn-Tewari-Das Sarma model with a Rashba-type spin-orbit coupling on the }\textbf{\textit{x-y}}\textbf{ plane and a large out-of-plane (perpendicular) Zeeman field along the }\textbf{\textit{z}}\textbf{-direction. Here we propose an alternative setup, where the topological superfluid phase is driven by applying an in-plane Zeeman field. This scheme offers a number of new features, notably Cooper pairings at finite centre-of-mass momentum (i.e., Fulde-Ferrell pairing) and gapless excitations in the bulk. As a result, a novel gapless topological quantum matter with inhomogeneous pairing order parameter appears. It features unidirected Majorana surface states at boundaries, which propagate in the same direction and connect two Weyl nodes in the bulk. We demonstrate the emergence of such an exotic topological matter and the associated Majorana fermions in spin-orbit coupled atomic Fermi gases and determine its parameter space. The implementation of our scheme in semiconductor/superconductor heterostructures is briefly discussed.

description: The extended high-energy gamma-ray (>100 MeV) emission which occurs well after the prompt gamma-ray bursts (GRBs) is usually explained as the afterglow synchrotron radiation. Here we report the analysis of the Fermi Large Area Telescope observations of GRB 130907A. A 55 GeV photon compatible with the position of the burst was found at about 5 hours after the prompt phase. The probability that this photon is associated with GRB 130907A is higher than 99.96%. The energy of this photon exceeds the maximum synchrotron photon energy at this time and its occurrence thus challenges the synchrotron mechanism as the origin for the extended high-energy >10 GeV emission. Modeling of the broad-band spectral energy distribution suggests that such high energy photons can be produced by the synchrotron self-Compton emission of the afterglow.

description: D mesons serve as excellent probes of hot and/or dense strongly interacting matter. They can provide insight into the restoration of chiral symmetry. The chiral condensate as well as other chirally odd condensates, such as certain four-quark condensates, are linked to order parameters of spontaneous chiral symmetry breaking. Thus, the evaluation of these higher order condensate contributions in the framework of QCD sum rules is of high interest. We present a general method for projecting Lorentz indices of ground state expectation values providing a crucial step towards a comprehensive calculation of higher order corrections to the operator product expansion of hadrons, especially D mesons, in a strongly interacting medium.

description: Mobile Ad hoc Networks (MANETs) are considered as a new paradigm of infrastructure-less mobile wireless communication systems. MANETs are being widely studied and it is the technology that is attracting a large variety of applications. Routing in MANETs is considered a challenging task due to the unpredictable changes in the network topology, resulting from the random and frequent movement of the nodes and due to the absence of any centralized control [1][2]. In this paper, we evaluate the performance of reactive routing protocols, Ad hoc On demand Distance Vector (AODV) and Dynamic Source Routing (DSR) and proactive routing protocol Destination Sequenced Distance Vector (DSDV). The major goal of this study is to analyze the performance of well known MANETs routing protocol in high mobility case under low, medium and high density scenario. Unlike military applications, most of the other applications of MANETs require moderate to high mobility. Hence it becomes important to study the impact of high mobility on the performance of these routing protocols. The performance is analyzed with respect to Average End-to-End Delay, Normalized Routing Load (NRL), Packet Delivery Fraction (PDF) and Throughput. Simulation results verify that AODV gives better performance as compared to DSR and DSDV.

description: We experimentally show that the neuron functions as a precise time-integrator, where the accumulated changes in neuronal response latencies, under complex and random stimulation patterns, are solely a function of a global quantity, the average time-lag between stimulations. In contrast, momentary leaps in the neuronal response latency follow trends of consecutive stimulations, indicating ultra-fast neuronal plasticity. On a circuit level, this ultra-fast neuronal plasticity phenomenon implements error-correction mechanisms and fast detectors for misplaced stimulations. Additionally, at moderate/high stimulation rates this phenomenon destabilizes/stabilizes a periodic neuronal activity disrupted by misplaced stimulations.
