description: Laser angle-resolved photoemission spectroscopy (ARPES) is employed to investigate the temperature (T) dependence of the electronic structure in BaFe2As2 across the magneto-structural transition at TN ~ 140 K. A drastic transformation in Fermi surface (FS) shape across TN is observed, as expected by first-principles band calculations. Polarization-dependent ARPES and band calculations consistently indicate that the observed FSs at kz ~ pi in the low-T antiferromagnetic (AF) state are dominated by the Fe3dzx orbital, leading to the two-fold electronic structure. These results indicate that magneto-structural transition in BaFe2As2 accompanies orbital-dependent modifications in the electronic structure.

description: Aim: Regression analysis is one of the statistical methods which helps to model the data and helps in prediction, a large data set with higher number of variables will often create problem due to its dimensionality and hence create difficulties to gather important information from the data, so it is a need of a method which can simultaneously choose important variables which contains most of the information and hence helps to fit the model. Least absolute shrinkage and selection operator (LASSO) is a popular choice for shrinkage estimation and variable selection. But LASSO uses the conventional least squares technique for feature selection which is very sensitive to outliers. As a result, when the data set is contaminated with bad observations (Outliers), the LASSO technique gives unreliable results, so in this paper the focus is to create a method which can resist to outliers in the data and helps in giving a meaningful result. Method: proposed a new procedure, a LASSO method by adding weights which uses the concept of redescending M-estimator, which can resist outliers in both dependent and independent variables. The observation with greater importance receives a higher weight and less weight to the least important observation. Findings: The efficiency of the proposed method has been studied in the real and simulation environment and compared with other existing procedures with measures like Median Absolute Error (MDAE), False Positive Rate (FPR), False Negative Rate (FNR), Mean Absolute Percentage Error (MAPE). The proposed method with the redescending M-estimator shows a higher resistance to outliers compared to conventional LASSO and other robust existing procedures. Conclusion: The study reveals that the proposed method outperforms other existing procedures in terms of MDAE, FPR, FNR and MAPE, indicating its superior performance in variables selection under outlier contaminated datasets.

description: We obtain the projected mass distributions for two Subaru/Suprime-Cam fields in the southwest region (r\simlt 60') of the Coma cluster (z=0.0236) by weak lensing analysis and detect eight subclump candidates. We quantify the contribution of background large-scale structure (LSS) on the projected mass distributions using SDSS multi-bands and photometric data, under the assumption of mass-to-light ratio for field galaxies. We find that one of eight subclump candidates, which is not associated with any member galaxies, is significantly affected by LSS lensing. The mean projected mass for seven subclumps extracted from the main cluster potential is = (5.06\pm1.30)10^12h^-1 M_sun after a LSS correction. A tangential distortion profile over an ensemble of subclumps is well described by a truncated singular-isothermal sphere model and a truncated NFW model. A typical truncated radius of subclumps, r_t\simeq 35 h^-1 kpc, is derived without assuming any relations between mass and light for member galaxies. The radius coincides well with the tidal radius, \sim42 h^-1 kpc, of the gravitational force of the main cluster. Taking into account the incompleteness of data area, a projection effect and spurious lensing peaks, it is expected that mass of cluster substructures account for 19 percent of the virial mass, with 13 percent statistical error. The mass fraction of cluster substructures is in rough agreement with numerical simulations.

description: Carbon nanotubes (CNTs) have large intrinsic carrier mobility due to weak acoustic phonon scattering. However, unlike two-dimensional metal-oxide-semiconductor field effect transistors (MOSFETs), substrate surface polar phonon (SPP) scattering has a dramatic effect on the CNTFET mobility, due to the reduced vertical dimensions of the latter. We find that for the Van der Waals distance between CNT and an SiO$_2$ substrate, the low-field mobility at room temperature is reduced by almost an order of magnitude depending on the tube diameter. We predict additional experimental signatures of the SPP mechanism in dependence of the mobility on density, temperature, tube diameter, and CNT - substrate separation.

description: A large fraction of white dwarfs are accreting or have recently accreted rocky material from their planetary systems, thereby polluting their atmospheres with elements heavier than helium. In recent years, the quest for mechanisms that can deliver planetesimals to the immediate vicinity of their central white dwarfs has stimulated a flurry of modelling efforts. The observed time evolution of the accretion rates of white dwarfs through their multi-Gyr lifetime is a crucial test for dynamical models of evolved planetary systems. Recent studies of cool white dwarfs samples have identified a significant decrease of the mass accretion rates of cool, old white dwarfs over Gyr timescales. Here, we revisit those results using updated white dwarf models and larger samples of old polluted H- and He-atmosphere white dwarfs. We find no compelling evidence for a strong decrease of their time-averaged mass accretion rates for cooling times between 1 and 8 Gyrs. Over this period, the mass accretion rates decrease by no more than a factor of the order of 10, which is one order of magnitude smaller than the decay rate found in recent works. Our results require mechanisms that can efficiently and consistently deliver planetesimals inside the Roche radius of white dwarfs over at least 8 Gyrs.

Performance Study of the Three-Piece and Y25 Bogies Using Frenet Geometric Analysis
Creators: name: Bettamin, Dario
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: In this thesis, a data-driven science DDS) approach, based on integrating nonlinear multibody system (MBS) formulations and new geometric concepts, is used to compare the performance of two widely used railroad bogies: the three-piece bogie, widely used in North America and other parts of the world, and the European Y25 bogie. Despite their popularity, such a comparative study, based on a MBS approach, is lacking in the literature. MBS algorithms are used to automatically construct and numerically solve the bogie nonlinear differential/algebraic equations (DAEs) to determine the bogie motion trajectories. To have a better understanding of the bogie dynamic behavior, new criteria are used in the comparative study performed in this investigation. To this end, a distinction is made between geometry of actual motion trajectories (AMT) and the track geometry. The AMT curves are described using the motion-dependent Frenet-Euler angles, referred to as Frenet bank, curvature, and vertical development angles, which differ from their counterparts used in the description of the track geometry. In particular, the Frenet bank angle defines the superelevation of the AMT curve osculating plane, referred to as the motion plane, which changes with time as the vehicle moves, distinguished from the fixed-in-time track super-elevation. This thesis explains the difference between the lateral track plane force balance used in practice to determine the balance speed and the Frenet force balance which is based on recorded motion trajectories. Computer simulations of bogies travelling on track, consisting of tangent, spiral, and curve sections, are performed with particular attention given to the deviations of the AMT curves from the track centerline. The results obtained in this study demonstrate the dependence of the AMT curve geometry on the wheelset forward motion, highlighting the limitations of tests performed using roller test rigs which do not allow longitudinal wheelset motion. Because all bogie performance criteria cannot be addressed in one study, this investigation is focused on recording centrifugal inertia forces of the two bogie types without making judgement on their overall performance. The contents of this thesis are based on the paper “Frenet Performance Evaluation of Railroad Vehicle Systems”, accepted for publication by the journal Acta Mechanica (Bettamin et al, 2021).

Appreciating Value: Fictional Economies of Art- and Self-Production

Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: This dissertation analyzes literary fictions published in the years preceding the 2008 financial crisis and continuing through its aftermath in the 2010s. It first examines how the novels in question are animated by notions of class inequity, and traces their shared suggestion that engagement with art, in particular literary fiction, is what allows for the imaginative possibility of upward class mobility. Second, it identifies the mechanisms by which these fictions construe art as the primary site of the immaterial labor of self-production. The market and finance logics that underpin these fictions are analyzed to consider art’s ontological relation to commerce, and how the narratives enfold the value of artworks and the value of persons into a single category. Third, it argues that writing, particularly in its institutional form of creative writing MFA programs, enters the cultural imagination as an idealized form of (creative) labor—one that is thought to produce value precisely through its function as a self-productive endeavor. Taken together, the novels analyzed in this study represent an entrenched logic of privatization, in which the appearance of the creative labor motif functions on the one hand to redescribe burgeoning inequity as the promise of upward class mobility, and on the other to reconfigure labor more generally as an ineluctably private undertaking on behalf of the self.

description: Shaft is the rotating component that transmits power from one place to another. The shafts are commonly subject to torsional and bending moments and combinations of these moments. In general, shafts are subjected to a combination of torsional and bending stresses. The design of a shaft is essential, subject to its strength and stress. This paper presents the reliability analysis of the shaft subjected to (a) twisting moment, (b) bending moment and (c) combined twisting and bending moment for which stress and strength follow the normal distribution.

description: Measurements of the double-differential charged pion production cross-section in the range of momentum 0.5 GeV/c < p < 8.0 GeV/c and angle 0.025 rad < theta <0.25 rad in collisions of protons on beryllium, carbon, nitrogen, oxygen, aluminium, copper, tin, tantalum and lead are presented. The data were taken with the large acceptance HARP detector in the T9 beam line of the CERN PS. Incident particles were identified by an elaborate system of beam detectors. The data were taken with thin targets of 5% of a nuclear interaction length. The tracking and identification of the produced particles was performed using the forward system of the HARP experiment. Results are obtained for the double-differential cross section mainly at four incident proton beam momenta (3 GeV/c, 5 GeV/c, 8 GeV/c and 12 GeV/c). Measurements are compared with the GEANT4 and MARS Monte Carlo generators. A global parametrization is provided as an approximation of all the collected datasets which can serve as a tool for quick yields estimates.

description: In many industries and applications, downtime or failure can have serious consequences, such as financial losses, safety hazards, or reputational damage. A hot standby unit can help minimize the impact of such events by providing a backup that can quickly and seamlessly take over in the event of a failure. Further, the question of as to how many hot standby units should be used also needs to be addressed. So, an N+1-Unit-system is investigated wherein N units are on hot standby, whereas one unit is operational and the system is such that the hot standby units can take over seamlessly if the single operative unit fails. The system breaks down completely when all the units fail. It is assumed that the failure rates of all the operational units and the redundant units will vary exponentially. To get different performability measurements, the regenerative point technique has been applied to optimize the value of N.
Strong gauge boson scattering at the LHC

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In the standard model with electroweak symmetry breaking through the Higgs mechanism, electroweak gauge-boson scattering amplitudes are large if the Higgs boson is heavy, and electroweak gauge interactions become strong. In theories with electroweak symmetry breaking through alternative mechanisms, there could be a strongly interacting gauge sector, possibly with resonances in an accessible energy region. In general, the scattering of longitudinally polarized massive gauge bosons can give information on the mechanism of spontaneous symmetry breaking. At energies below the symmetry breaking scale, the equivalence theorem relates the scattering amplitudes to those of the "would-be" Goldstone modes. In the absence of Higgs bosons, unitarity would be restored by some new physics which can be studied through WW scattering. Some representatives models are discussed. Isolating WW scattering at a hadron collider from other contributions involving W emission from parton lines needs a good understanding of the backgrounds. Resonances, if they exist below about a TeV, would be feasible of observation at the LHC.

Highly Reliable Products

description: The reliability study of such incredibly reliable items is inappropriate for the use of failure time data analysis and testing methodologies. More trustworthy information can be obtained from degradation data than from standard censored failure-time data, especially in cases where few or no failures are anticipated. The market for lighting has given a lot of attention to high-power white light emitting diodes (HPWLEDs). But as one of the more dependable electronic goods, it may not be expected to fail in either a traditional or even an accelerated life test. DDDM, or data-driven degradation methodology, is used in this research. Using data on lumen maintenance gathered from the IES LM-80-08 lumen maintenance test standard and based on the general degradation path model, the dependability of HPWLED was predicted. Testing such devices in typical working situations, and occasionally even under worse conditions, is difficult enough without trying to collect an adequate amount of time-to-failure data. Modern items are made with superb quality and high reliability in mind. Some safety-critical parts and systems are even made to last for an incredibly long time in order to prevent the disastrous effects of probable breakdowns. A cumulative damage model based on stochastic degradation processes has been developed in this paper. A suitable numerical representation is used to support the analytical findings. As a result, the degradation analysis approach has been developed to address dependability modeling issues using data on product degradation gleaned from historical records or degradation testing.

description: We introduce, for the first time, a new class of Birnbaum-Saunders nonlinear regression models potentially useful in lifetime data analysis. The class generalizes the regression model described by Rieck and Nedelman [1991, A log-linear model for the Birnbaum-Saunders distribution, Technometrics, 33, 51-60]. We discuss maximum likelihood estimation for the parameters of the model, and derive closed-form expressions for the second-order biases of these estimates. Our formulae are easily computed as ordinary linear regressions and are then used to define bias corrected maximum likelihood estimates. Some simulation results show that the bias correction scheme yields nearly unbiased estimates without increasing the mean squared errors. We also give an application to a real fatigue data set.

description: Using molecular dynamics we investigate the thermodynamics, dynamics and structure of 250 diatomic molecules interacting by a core-softened potential. This system exhibits thermodynamics, dynamics and structural anomalies: a maximum in density-temperature plane at constante pressure and maximum and minimum points in the diffusivity and translational order parameter against density at constant temperature. Starting with very dense systems and decreasing density the mobility at low temperatures first increases, reach a maximum, then decreases, reach a minimum and finally increases. In the pressure-temperature phase diagram the line of maximum translational order parameter is located outside the line of diffusivity extrema that is enclosing the temperature of maximum density line. We compare our results with the monomeric system showing that the anisotropy due to the dumbbell leads to a much larger solid phase and to the appearance of a liquid crystal phase. the double ranged thermodynamic and dynamic anomalies.

description: Multiobjective evolutionary learning (MOEL) has demonstrated its advantages of training fairer machine learning models considering a predefined set of conflicting objectives, including accuracy and different fairness measures. Recent works propose to construct a representative subset of fairness measures as optimisation objectives of MOEL throughout model training. However, the determination of a representative measure set relies on dataset, prior knowledge and requires substantial computational costs. What's more, those representative measures may differ across different model training processes. Instead of using a static predefined set determined before model training, this paper proposes to dynamically and adaptively determine a representative measure set online during model training. The dynamically determined representative set is then used as optimising objectives of the MOEL framework and can vary with time. Extensive experimental results on 12 well-known benchmark datasets demonstrate that our proposed framework achieves outstanding performance compared to state-of-the-art approaches for mitigating unfairness in terms of accuracy as well as 25 fairness measures although only a few of them were dynamically selected and used as optimisation objectives. The results indicate the importance of setting optimisation objectives dynamically during training.

Modulating Semantic Integration in the Right Hemisphere: A Transcranial Direct Current Stimulation Study
Creators: name: Christofalos, Andriana
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Prior research has shown that the right hemisphere is essential for integrating information across a passage to form a coherent thematic meaning. The aim of this dissertation is to evaluate right hemisphere semantic integration processes by directly manipulating the neural excitability of the left or right hemisphere using transcranial direct current stimulation (tDCS) while participants read passages and complete a lexical decision task. For the lexical decision task, participants were presented with either a target word related to the passage’s local (word-level) context, a target word related to the passage’s global (thematic) context, or a non-word. Because processing global information requires semantic integration processes, right hemisphere anodal (i.e., active) stimulation was predicted to increase the speed and accuracy of lexical decision responses to global targets compared to sham (i.e., inactive) and left hemisphere anodal stimulation. Contrary to predictions, results indicated no effect of tDCS condition, such that participants in each stimulation condition revealed similar patterns of response time and accuracy. However, participants responded faster to local targets compared to global targets, regardless of stimulation condition. This finding provides additional evidence for fast activation of local contextual information and relatively slower activation of global contextual information during discourse comprehension. Future directions are discussed regarding the absence of a tDCS effect on lexical decision response time and accuracy.
Municipal Capital Budgeting: A Qualitative Comparative Analysis of Sample Illinois Municipalities

description: Public infrastructure is the lifeblood of every community and high-quality municipal capital assets facilitate economic development and prosperity. Despite its importance, capital budgeting and spending is often neglected by the responsible governments. As a result, the U.S. state and local infrastructure is degrading and in a state of decay. Using a sample of thirty-two municipal governments in the state of Illinois, this study employs extensive case studies as well as a suit of Qualitative Comparative Analysis (QCA) techniques in order to investigate, first, factors that affect approach to municipal capital budgeting, and second, impacts that approach to municipal capital budgeting could have on level of capital and maintenance spending. The results indicate that large municipal governments and/or municipalities where a hired manager – as the Chief Administrative Officer (CAO) – leads the capital budgeting efforts tend to have a professional and comprehensive approach to capital budgeting, while smaller governments or municipalities with political institutional forms tend to have a more shortsighted and unprofessional approach to capital budgeting. Finally, the results also show that approach to municipal capital budgeting matters and sample governments with a professional approach to capital budgeting do, in fact, have higher infrastructure and maintenance spending than cases with an ad-hoc and unprofessional approach.

description: Individuals with schizophrenia spectrum disorders experience social functioning impairments in relation to the general population. Social cognition has been identified as a primary contributor of social functioning deficits, and individuals with schizophrenia spectrum disorders have been found to have difficulties in all domains of social cognition. Most therapeutic interventions have been found to have limited effect on the improvement of social cognition. The current study focuses on the implementation of a computerized social cognitive intervention designed to improve several domains of social cognition in individuals with schizophrenia spectrum disorders, including theory of mind. This intervention was found to lead to change in implicit theory of mind but not explicit theory of mind or social functioning. Possible reasons for this pattern of changes and the implications of these findings are discussed.

description: This paper deals with the reliability modelling of a parallel cold standby system of four units. The units operate in two phases; phase-I and phase-II. In phase-I, two identical units (called main units) work in parallel and the other two identical units (called duplicate units) have been taken as spare in cold standby. The units of phase-I and of the phase-II are not identical. The priority to repair the units of phase-I has been given over the repair of the units of the phase-II. However, no priority is given for operation of the units of both phases. There is a single repair facility which tackles all types of faults whenever occurred in the system. After repair each unit works as new and the switches devices are considered as perfect. The repair time of the units follows arbitrary probability distribution while the failure time of the units is assumed as constant. The behaviour of mean sojourn time (MST), transition probabilities, mean time to system failures (MTSF), availability, expected number of repairs for both phase-I and phase-II units, expected number of visits of the server, busy period of the server and finally the profit function are obtained in steady state by making use of well-known semi-Markov process (SMP) and Regenerative Point Technique (RPT) for arbitrary values of the parameters in steady state. Novelty and Application: A four-unit system is configured in two phases namely; phase-I and phase-II under some novel assumptions with a practical visualization in metallic bush manufacturing industries.

description: I present the next-to-next-to-leading-logarithm (NNLL) resummation of soft and collinear gluon corrections to single top quark production in the s channel. Attaining NNLL accuracy involves the calculation of the two-loop soft anomalous dimension for the partonic subprocesses. Finite-order expansions of the resummed cross section are calculated through next-to-next-to-leading order (NNLO). Numerical results are presented for s-channel single top quark production at the Tevatron and the LHC, including the dependence of the cross sections on the top quark mass and the uncertainties in the theoretical prediction. The higher-order corrections are significant for energies at both colliders and they decrease the theoretical uncertainty.

description: Long Short Term Memory LSTM-based structures have demonstrated their efficiency for daily living recognition activities in smart homes by capturing the order of sensor activations and their temporal dependencies. Nevertheless, they still fail in dealing with the semantics and the context of the sensors. More than isolated id and their ordered activation values, sensors also carry meaning. Indeed, their nature and type of activation can translate various activities. Their logs are correlated with each other, creating a global context. We propose to use and compare two Natural Language Processing embedding methods to enhance LSTM-based structures in activity-sequences classification tasks: Word2Vec, a static semantic embedding, and ELMo, a contextualized embedding. Results, on real smart homes datasets, indicate that this approach provides useful information, such as a sensor organization map, and makes less confusion between daily activity classes. It helps to better perform on datasets with competing activities of other residents or pets. Our tests show also that the embeddings can be pretrained on different datasets than the target one, enabling transfer learning. We thus demonstrate that taking into account the context of the sensors and their semantics increases the classification performances and enables transfer learning.

description: In this paper, a stochastic model for utensils manufacturing system with preventive maintenance (PM) is analysed in detail. The operation is affected by variation in the temperature dependent maintenance. The entire manufacturing process of utensils goes through four subsystems viz., Circle cutting subsystem 1, Pressing subsystem 2, Spinning subsystem 3 and Polishing & Packing 4. The system has series structure of all the subsystems. The system is put under PM on the winter time and after PM it operates as new. The PM time distributions are considered as arbitrary and the time to failure as well as repair of each subsystem follows a negative exponential distribution. All random variables are statistically independent. Several measures for evaluating the effectiveness of a system, including mean time to system failure (MTSF), system availability (in summer and winter), busy period of repairman and expected number of repairs (in summer and winter) are derived using a regenerative point technique and Markov process. The system is also analysed for particular values of the parameters.

Palmitoyl-protein Thioesterase 1 in Developmental Plasticity and Infantile Neuronal Ceroid Lipofuscinosis

description: Infantile neuronal ceroid lipofuscinosis (CLN1) is a pediatric neurodegenerative disease that affects children and results in death by age 5. Mutations in the neuronal enzyme palmitoyl-protein thioesterase 1 (PPT1) cause CLN1. PPT1 is a depalmitoylating enzyme—it removes palmitic acid from proteins that have been posttranslationally palmitoylated. Palmitoylation dynamically influences the trafficking and membrane association of proteins, especially at synapses. Neurodevelopmental plasticity of synapses and the neuronal circuits they make up is crucial for long-term brain function. We hypothesized that loss of PPT1 function compromises neurodevelopmental synaptic plasticity and thereby drives the progression of CLN1. Therefore, we studied the role of Ppt1 in the well-characterized developmental plasticity of the visual cortex in the Ppt1-/- mouse model of CLN1. N-methyl-D-aspartate (NMDA) receptors in the visual cortex undergo a developmental shift in their composition that coincides with the maturation of neuronal circuits. The GluN2B subunits that are dominant in early life are replaced by NMDA receptors containing, instead, GluN2A. I discovered that this process is idled in the CLN1 visual cortex such that the cell biological and physiological features of the immature, GluN2B-NMDA receptors persist in Ppt1-/- neurons. This, in part, leaves Ppt1-/- neurons vulnerable to excitotoxicity. In a separate line of experiments, I investigated how Ppt1 impacts a mechanism of homeostatic plasticity known as synaptic scaling, which counterbalances Hebbian plasticity. The insertion of calcium permeable AMPA receptors that constitutes synaptic scaling up was exaggerated in Ppt1-/- neurons in vitro and in vivo. Palmitoyl-proteomics showed that A kinase anchor protein 5 (Akap5) and associated signaling molecules are hyperpalmitoylated in Ppt1-/- neurons. This pathway regulates synaptic scaling and links synaptic calcium activity to neuroinflammation via activation of nuclear factor of activated T-cells (NFAT), demonstrating a direct line between these processes for the first time in CLN1. Finally, two-photon calcium imaging in awake animals revealed that Ppt1-/- visual cortical neurons are hypersynchronous, suggesting a failure to de-synchronize with age in the CLN1 brain. Taken together, this work demonstrates that depalmitoylation by Ppt1 regulates synaptic plasticity mechanisms engaged in neurodevelopment that, when disrupted, lead to circuit-wide defects that portend CLN1 symptoms.
Transport Dynamics of Quark-Gluon Plasma in Perturbative QCD with Magnetic fields/Vorticity

description: In this defense, I present my research on transport dynamics of the quark-gluon plasma (QGP) with magnetic field and/or vorticity by using the thermal perturbative Quantum Chromodynamics(pQCD) approach. The first main topic focuses on studying the interplay between the QCD interactions and magnetic field, where an effective kinetic theory of the lowest Landau level quarks is formulated, from which the quark mass dependence of the finite electrical conductivity is found. Shear viscosity that governs the rate of momentum transfer, is also affected by the presence of the magnetic field. A full numerical result for the magnetic-dependent shear viscosity is provided. The second main topic will be on the spin dynamics of QGP, where a novel quantum kinetic description of the spin polarization of massive quarks is first formulated in the context of pQCD. This framework shows that the order of time scale of spin polarization is the same as that of charge transport and shear viscosity, which is not captured by usual classical kinetic theory. In the third topic, I will introduce our novel construction of the non-dissipative second-order hydrodynamics for a slowly rotating fluid. New transport coefficients arise and are constrained by the second law of thermodynamics. We demonstrate that the extension of hydrodynamics by the spin variable is equivalent to modifying conventional hydrodynamics by a set of second-order terms satisfying the relations we derived. We point out that a novel contribution to the heat current orthogonal to vorticity and temperature gradient reminiscent of the thermal Hall effect is constrained by the second law.

description: Handling of high-dimensional data is an important issue in robust literature. For analyzing data, location measure plays a vital role in almost all statistical methods. The location parameter of a distribution is used to find the central value. Many computational methods are used to find the measure of location for analyzing data. The data depth procedure is one approach to finding the true representative of the entire data and it is one of the key concepts in multivariate data analysis. Data depth is a term used to describe how deep a particular point is inside the broad multivariate data cloud. Instead of the typical smallest to biggest rank, the sample points can be ordered from the center outward. Mahalanobis depth is one of the popular depth procedures. The traditional approach used to find Mahalanobis depth is based on Mahalanobis distance, it is based on the classical sample mean vector and covariance matrix. So the conventional Mahalanobis depth is sensitive to outliers and may fail when the data is contaminated. To solve this problem, the Minimum Covariance Determinant (MCD) estimators are used instead of classical estimators. However, the MCD estimators cannot be calculated in high dimensional data sets, in which the variable number is higher than the subset size. To calculate Mahalanobis depth values in high dimensional data, propose a new depth function namely the Robust Regularized Mahalanobis Depth (RRMD), which can be calculated in high dimensional data sets. The proposed procedure is based on Minimum Regularized Covariance Determinants (MRCD) estimators, this study shows that the proposed depth function is successful in finding the deepest point in high dimensional data sets with real and simulation studies up to a certain level of contamination.

description: In this article, we develops optimal sample size for acceptance number (zero and one) for single and double sampling plans by fixing consumer’s risk and test completion time, with the assumption that, the life of the item follows logistic family of distributions (i.e. Logistic Rayleigh distribution/Logistic exponential distribution/Logistic Weibull distribution). The optimal size obtained for single and double sampling plans for logistic family of distributions are compared with baseline distributions and the results are discussed.
