LIVE VIRTUAL MACHINE MIGARTION BASED ON MEMORY COMPRESSION AND SMART TERMINATION CRITERIA
Creators: name: GEBREMICHAEL GEBRU
Publisher: name: Zenodo
Year: 2020

description: In this thesis, researchers have studied the area of virtualization. The focus has been on the sub-area live migration, a technique that allows seamless migration of a virtual machine from one physical machine to another physical machine. Live virtual machine migration refers to the process of moving a running virtual machine or application between different physical machines without disconnecting the client or application. Memory, storage, and network connectivity of the virtual machine are transferred from the original guest machine to the destination. Live virtual machine migration is an attractive technique used to utilize resources in cloud-based data centers through load balancing, fault tolerance, and system maintenance. The performance of live VM migration is measured using different parameters such as total migration time, downtime, and total memory page transferred. This study has proposed a solution to the problem of a huge number of memory pages are being dirtied during the iterative phase of pre-copy live VM migration. A live migration based on combined memory compression and smart termination criteria is proposed it operate as follows: before memory pages are being transferred compression, process is undertaken on those pages. While memory pages are transferred from source host to destination host iteratively, a smart termination criterion is used as a control unit and, when and how the iterative phase of pre-copy will be executed is examined using this controlling system.

title: The Application of a User-Centered Design Framework to a Static Topographic Ski Touring Map

description: This research fills the cartographic gap in ski touring maps with a new usercentered design (UCD) framework that links the ski tourers’ needs and demands to a new map design. Ski touring is an activity where the recreationists ascend and descend the mountain outside the slopes of ski resorts. Ski tourers use maps for planning, navigating, and reflecting on ski tours. Static maps generally follow a traditional map production process, in which the user is considered but not involved (Darkes, 2017). This research incorporates two UCD approaches of Roth, Ross and MacEachren (2015) and Tsou and Curran (2008) into the production process, resulting in a new UCD framework that leads to a more tailored and user-central end product.The developed approach was applied to create a ski touring map of the Schladming-Dachstein area (Steiermark, Austria). This new UCD framework involves (i) accommodating the needs and demands of the target group through an in-depth literature review, comparing existing ski touring maps and interviewing the target group; (ii) establishing the map’s purpose and design considerations; (iii) designing the map itself; (iv) evaluating the map using a survey by ski tourers, and (v) finalizing the design tailored to the needs and demands for ski touring.The final product of this research is a ski touring map design, where a user-centered design framework was successfully followed. The map design met the needs and demands of the ski tourers determined in this research. This research not only fills the niche market of ski touring maps but can also inspire other cartographers with step-to-step research on user-centered cartographic design for static maps.
Subcanonical points on projective curves and triply periodic minimal surfaces in the Euclidean space

description: A point $p$ on a smooth complex projective curve $C$ of genus $g>3$ is subcanonical if the divisor $(2g-2)p$ is canonical. In the moduli space of pointed curves, the subcanonical locus is described by pairs $(C,p)$ as above, and it consists of three irreducible components of dimension $2g-1$. Apart from the hyperelliptic component $\mathcal{G}_g^{hyp}$, the other components $\mathcal{G}_g^{odd}$ and $\mathcal{G}_g^{even}$ depend on the parity of $h^0(C,(g-1)p)$, and their general points satisfy $h^0(C,(g-1)p)=1$ and $2$, respectively. In this paper, we study the subloci of pairs $(C,p)$ such that $h^0(C,(g-1)p)$ is at least $r+1$ and it has the same parity as $r+1$. In particular, we provide a lower bound on their dimension, and we prove its sharpness for $r<4$. As an application, we further give an existence result for triply periodic minimal surfaces immersed in the 3-dimensional Euclidean space, completing a previous result of the second author.

B 87, 165132 (2013)], the authors compared results of numerical renormalization group and a perturbative approach for the dependence on temperature T and magnetic field B of the conductance through a quantum dot described by the impurity Anderson model, for small T and B. We show that the equation used to extract the dependence on B from NRG results is incorrect out of the particle-hole symmetric case. As a consequence, in the Kondo regime, the correct NRG results have a weaker dependence on B and the disagreement between both approaches increase.

description: Let X be an algebraic variety of characteristic zero. Terminal valuations are defined in the sense of the minimal model program, as those valuations given by the exceptional divisors on a minimal model over X. We prove that every terminal valuation over X is in the image of the Nash map, and thus it corresponds to a maximal family of arcs through the singular locus of X. In dimension two, this result gives a new proof of the theorem of Fernández de Bobadilla and Pe Pereira stating that, for surfaces, the Nash map is a bijection.

description: Taking inspiration from lattice QCD data, we argue that a finite non-perturbative contribution to the quark mass is generated as a consequence of the dynamical phenomenon of spontaneous chiral symmetry breaking, in turn triggered by the explicitly breaking of chiral symmetry induced by the critical Wilson term in the action. In pure lattice QCD this mass term cannot be separated from the unavoidably associated linearly divergent contribution. However, if QCD is enlarged to a theory where also a scalar field is present, coupled to an SU(2) doublet of fermions via a Yukawa and a Wilson-like term, then in the phase where the scalar field takes a non-vanishing expectation value, a dynamically generated and "naturally" light fermion mass (numerically unrelated to the expectation value of the scalar field) is conjectured to emerge at a critical value of the Yukawa coupling where the symmetry of the model is maximally enhanced. Masses dynamically generated in this way display a natural hierarchy according to which the stronger is the strongest of the interactions the fermion is subjected to the larger is its mass.

description: Response calibration is the process of inferring how much the measured data depend on the signal one is interested in. It is essential for any quantitative signal estimation on the basis of the data. Here, we investigate self-calibration methods for linear signal measurements and linear dependence of the response on the calibration parameters. The common practice is to augment an external calibration solution using a known reference signal with an internal calibration on the unknown measurement signal itself. Contemporary self-calibration schemes try to find a self-consistent solution for signal and calibration by exploiting redundancies in the measurements. This can be understood in terms of maximizing the joint probability of signal and calibration. However, the full uncertainty structure of this joint probability around its maximum is thereby not taken into account by these schemes. Therefore better schemes -- in sense of minimal square error -- can be designed by accounting for asymmetries in the uncertainty of signal and calibration. We argue that at least a systematic correction of the common self-calibration scheme should be applied in many measurement situations in order to properly treat uncertainties of the signal on which one calibrates. Otherwise the calibration solutions suffer from a systematic bias, which consequently distorts the signal reconstruction. Furthermore, we argue that non-parametric, signal-to-noise filtered calibration should provide more accurate reconstructions than the common bin averages and provide a new, improved self-calibration scheme. We illustrate our findings with a simplistic numerical example.

description: We study a nonrelativistic quantum mechanical particle on an interval of finite length with a Hamiltonian that has a $p^3$ correction term, modelling potential low energy quantum gravity effects. We describe explicitly the $U(3)$ family of the self-adjoint extensions of the Hamiltonian and discuss several subfamilies of interest. As the main result, we find a family of self-adjoint Hamiltonians, indexed by four continuous parameters and one binary parameter, whose spectrum and eigenfunctions are perturbatively close to those of the uncorrected particle with Dirichlet boundary conditions, even though the Dirichlet condition as such is not in the $U(3)$ family. Our boundary conditions do not single out distinguished discrete values for the length of the interval in terms of the underlying quantum gravity scale.

description: Ultracold atoms in optical lattices serve as a tool to model different physical phenomena appearing originally in condensed matter. To study magnetic phenomena one needs to engineer synthetic fields as atoms are neutral. Appropriately shaped optical potentials force atoms to mimic charged particles moving in a given field. We present the realization of artificial gauge fields for the observation of anomalous Hall effect. Two species of attractively interacting ultracold fermions are considered to be trapped in a shaken two dimensional triangular lattice. A combination of interaction induced tunneling and shaking can result in an emergent Dice lattice. In such a lattice the staggered synthetic magnetic flux appears and it can be controlled with external parameters. The obtained synthetic fields are non-Abelian. Depending on the tuning of the staggered flux we can obtain either anomalous Hall effect or its quantized version. Our results are reminiscent of Anomalous Hall conductivity in spin-orbit coupled ferromagnets.

description: For the demonstration of ultra-wideband bandwidth and pencil-beamforming, the terahertz (THz)-band has been envisioned as one of the key enabling technologies for the sixth generation networks. However, the acquisition of the THz channel entails several unique challenges such as severe path loss and beam-split. Prior works usually employ ultra-massive arrays and additional hardware components comprised of time-delayers to compensate for these loses. In order to provide a cost-effective solution, this paper introduces a sparse-Bayesian-learning (SBL) technique for joint channel and beam-split estimation. Specifically, we first model the beam-split as an array perturbation inspired from array signal processing. Next, a low-complexity approach is developed by exploiting the line-of-sight-dominant feature of THz channel to reduce the computational complexity involved in the proposed SBL technique for channel estimation (SBCE). Additionally, based on federated-learning, we implement a model-free technique to the proposed model-based SBCE solution. Further to that, we examine the near-field considerations of THz channel, and introduce the range-dependent near-field beam-split. The theoretical performance bounds, i.e., Cramér-Rao lower bounds, are derived both for near- and far-field parameters, e.g., user directions, beam-split and ranges. Numerical simulations demonstrate that SBCE outperforms the existing approaches and exhibits lower hardware cost.

description: Non-perturbative quantum corrections to supersymmetric black hole entropy often involve nontrivial number-theoretic phases called Kloosterman sums. We show how these sums can be obtained naturally from the functional integral of supergravity in asymptotically AdS_2 space for a class of black holes. They are essentially topological in origin and correspond to charge-dependent phases arising from the various gauge and gravitational Chern-Simons terms and boundary Wilson lines evaluated on Dehn-filled solid 2-torus. These corrections are essential to obtain an integer from supergravity in agreement with the quantum degeneracies, and reveal an intriguing connection between topology, number theory, and quantum gravity. We give an assessment of the current understanding of quantum entropy of black holes.

description: Social status, defined as the relative rank or position that an individual holds in a social hierarchy, is known to be among the most important motivating forces in social behaviors. In this paper, we consider the notion of status from the perspective of a position or title held by a person in an enterprise. We study the intersection of social status and social networks in an enterprise. We study whether enterprise communication logs can help reveal how social interactions and individual status manifest themselves in social networks. To that end, we use two enterprise datasets with three communication channels --- voice call, short message, and email --- to demonstrate the social-behavioral differences among individuals with different status. We have several interesting findings and based on these findings we also develop a model to predict social status. On the individual level, high-status individuals are more likely to be spanned as structural holes by linking to people in parts of the enterprise networks that are otherwise not well connected to one another. On the community level, the principle of homophily, social balance and clique theory generally indicate a "rich club" maintained by high-status individuals, in the sense that this community is much more connected, balanced and dense. Our model can predict social status of individuals with 93% accuracy.

description: We characterize the Cosmic Infrared Background (CIB)-lensing bispectrum which is one of the contributions to the three-point functions of Cosmic Microwave Background (CMB) maps in harmonic space. We show that the CIB-lensing bispectrum has a considerable strength and that it can be detected with high significance in the Planck high-frequency maps. We also present forecasts of the contamination on different shapes of the primordial non-Gaussianity $f_{nl}$ parameter produced by the CIB-lensing bispectrum and by the extragalactic point sources bispectrum in the Planck high-resolution CMB anisotropy maps. The local, equilateral and orthogonal shapes are considered for 'raw' single-frequency (i.e., without applying any component separation technique) and foreground-reduced Planck temperature maps. The CIB-lensing correlation seems to mainly affect orthogonal shapes of the bispectrum - with Δ$f_{nl}$ = -21 and -88 for the 143 and 217 GHz bands respectively - while point sources mostly impact equilateral shapes, with Δ$f_{nl}$ = 160, 54 and 60 at 100, 143 and 217 GHz. However, the results indicate that these contaminants do not induce any relevant bias on Planck $f_{nl}$ estimates when foreground-reduced maps are considered: using SEVEM for the component separation we obtain Δ$f_{nl}$ = 10.5 due to the CIB-lensing and Δ$f_{nl}$ = 30.4 due to point sources, corresponding to 0.30σ and 0.45σ in terms of the Planck 2013 $f_{nl}$ uncertainty. The component separation technique is, in fact, able to partially clean the extragalactic source contamination and the bias is reduced for all the shapes. We have further developed single- and multiple-frequency estimators based on the Komatsu, Spergel & Wandelt (2005) formalism that can be implemented to efficiently detect this signal.

description: Body weight, as an essential physiological trait, is of considerable significance in many applications like body management, rehabilitation, and drug dosing for patient-specific treatments. Previous works on the body weight estimation task are mainly vision-based, using 2D/3D, depth, or infrared images, facing problems in illumination, occlusions, and especially privacy issues. The pressure mapping mattress is a non-invasive and privacy-preserving tool to obtain the pressure distribution image over the bed surface, which strongly correlates with the body weight of the lying person. To extract the body weight from this image, we propose a deep learning-based model, including a dual-branch network to extract the deep features and pose features respectively. A contrastive learning module is also combined with the deep-feature branch to help mine the mutual factors across different postures of every single subject. The two groups of features are then concatenated for the body weight regression task. To test the model's performance over different hardware and posture settings, we create a pressure image dataset of 10 subjects and 23 postures, using a self-made pressure-sensing bedsheet. This dataset, which is made public together with this paper, together with a public dataset, are used for the validation. The results show that our model outperforms the state-of-the-art algorithms over both 2 datasets. Our research constitutes an important step toward fully automatic weight estimation in both clinical and at-home practice. Our dataset is available for research purposes at: https://github.com/USTCWzy/MassEstimation.

Creators: name: Ochoa Ortiz, Hector
Publisher: name: TU Wien

Subjects: subject: routing
subject: OpenStreetMap

description: Pedestrians, contrasting with vehicles, do not take routes only over defined linear features. Routing networks have historically ignored that pedestrians have a higher degree of freedom, and can naturally move through open spaces. On top of that, our real world is not static, it changes dynamically. Routing apps also fail in most cases to portray the varying character of the reality on the ground.Combining both time dependent, and open areas I can define a complex scenario called Time Dependent Open Areas (TDOAs).The “ecosystem” of OSM applications provides a starting point for my solution, and paves the way for the development of derived work on an already established base.I propose a standard way (schema) of mapping TDOAs, deriving from the current OSM time dependent and pedestrian open areas schemas.After that, I combine time dependent and open area routing algorithms to create a single unified routing service for TDOAs. The unified routing service uses OSM data and the new schema to generate the routing graph.TDOAs are demonstrated to be representable in OSM. My suggested proposal is able to adapt to many different realities before not mapped or considered, while still preserving OSM philosophy.Routing is also proved to be possible, albeit the current approach is not perfect. Work should and must be redefined in future iterations, to fix the adjacent areas border problem.Several use cases and future work is proposed. This thesis should just be considered as the stepping stone in a much broader topic, yet to be developed.

In this scope, liveness comprises both the orchestration of the experiential and the continuous pursuit of immediacy, presence, shared experience, and authenticity in contexts marked precisely by mediation. Liveness emerges as the productively contradictory experience of immediate connection through media. This thesis deploys liveness both as its central object of enquiry and as a conceptual device to examine mediation as an experiential process in and of itself. Through a diary-interviewing study conducted with London-based social media users, it explores how ordinary experiences of and with habitual social media challenge, reaffirm, or expand our available conceptions of liveness, and assesses the extent to which liveness can be useful to illuminate our understanding of lived experiences with and of social media more broadly. In so doing, the thesis advances a critical phenomenology of mediation, focusing on perceptual processes to examine and interrogate the structures of lived experience without disregarding the social, technical, economic, and political forces that underpin the social media manifold. In examining liveness through some of the organising principles of phenomenology – temporality, spatiality, intersubjectivity, and embodiment – this thesis explores four existential quests as enacted through technical mediation. They are: the ‘real-time’ experience, the experience of ‘being there’, ‘getting involved in a shared experience’, and the ‘authentic’ experience. I conclude that the conceptual value of liveness and its relevance and endurance as a key topic of interest for media studies rest in its intrinsically contested, disputed nature of as-if-ness – of a mediation that claims also to be immediate – and in how those tensions are renewed, refashioned, and updated with the development and habituation of new technologies of communication.

description: The saturation of the photoconductivity due to 1s-2p+ shallow donor transitions in n-GaAs has been investigated using a high power cw-FIR-laser. Magnetic field strengths were chosen in such a way that 2p+ energy levels were either below or above the N=0 conduction band Landau level. In the former case 1s-p+ transitions are found to be inhomogeneously broadened with a saturation intensity as low as 0.84 mW/cm2, giving an effective lifetime of the 2p+ state of 1.5 mgrs. Above the band edge the integrated photoconductivity does not saturate though the intensity-normalized peak photosignal decreases and the linewidth increases with raising intensity. This strange behaviour is tentatively attributed to optical excitations of 2p+ electrons to higher lying electron Landau states.

description: An explicit full nulling scheme for cosmic shear observations is presented. It makes possible the construction of shear maps from extended source distributions for which the lens distance distribution is restricted to a definite interval. Such a construction allows to build totally independent shear maps, at all scales, that can be taken advantage of to constrain background cosmological parameters and systematics using the full statistical power of cosmic shear observations. Another advantage of such construction is that, as the lens redshift distribution can be made arbitrarily narrow, scale mixing due to projection effects can be limited allowing controlled predictions on the large scale shear power spectrum from perturbation theory calculations.

Hot Asphalt Mixtures (HMA) is composite of mineral aggregates, asphalt binder, and air voids. Mineral aggregate is covered about 95 percent of the total mixture. In asphalt pavement production, aggregate gradation is specified in a large percent passing range to use locally available material and to be economical. This large gap of the aggregate gradation specification range alters the performance of the asphalt concrete by change the aggregate surface area. The aggregate surface area has a critical role in the hot mix asphalt performance by altering the coated asphalt film thickness on the aggregate surface and this controls overall mixture properties. Various studies have shown that the variation aggregate surface area has a significant effect on the performance of asphalt concrete pavements by using Marshall Test methods. This study was mainly evaluated the effect of aggregate surface area on the mixture volumetric properties and moisture damage. Different aggregate surface areas were determined in the blending aggregate gradation percent passing specification range by multiplying empirical surface area factor. Using 3.12m2/kg, 4.58m2/kg, 6.19m2/kg, 7.93m2/kg, and 9.64m2/kg aggregate surface areas a number of trial mixes have been prepared using the Marshal Mix design method. The stability, flow, volumetric properties, and moisture resistance of the hot mix asphalt were discussed.

description: The competition between superconductivity and charge density wave (CDW) order in underdoped cuprates has now been widely reported, but the role of disorder in this competition has yet to be fully resolved. A central question is whether disorder sets the length scale of the CDW order, for instance by pinning charge density fluctuations or disrupting an otherwise long range order. Using resonant soft x-ray scattering, we investigate the sensitivity of CDW order in YBa$_2$Cu$_3$O$_{6+x}$ (YBCO) to varying levels of oxygen disorder. We find that quench cooling YBCO$_{6.67}$ (YBCO$_{6.75}$) crystals to destroy their o-V and o-VIII (o-III) chains decreases the intensity of the CDW superlattice peak by a factor of 1.9 (1.3), but has little effect on the CDW correlation length, incommensurability, and temperature dependence. This reveals that while quenched oxygen disorder influences the CDW order parameter, the spatial extent of the CDW order is insensitive to the level of quenched oxygen disorder and may instead be a consequence of competition with superconductivity.

TRANSIENT SCATTERING FROM DIELECTRIC CYLINDERS - E-FIELD, H-FIELD, AND COMBINED FIELD SOLUTIONS
Creators: name: Vechinski, Douglas
name: Rao, Sadasiva
Publisher: name: Auburn University
Year: 1992

description: In this work, the problem of transient scattering by arbitrarily shaped two-dimensional dielectric cylinders is solved using the marching-on-in-time technique. The dielectric problem is approached via the equivalence principle. Three different formulations, namely, the electric field integral equation formulation, the magnetic field integral equation formulation and the combined field integral equation formulation are considered. Numerical results are presented for two cross sections, namely, a circle and a square, and compared with inverse discrete Fourier transform (IDFT) techniques. In each case, good agreement is obtained with the IDFT solution.

description: We provide an introduction into the formulation of non-relativistic quantum mechanics using the Wigner phase-space distribution function and apply this concept to two physical situations at the interface of quantum theory and general relativity: (i) the motion of an ensemble of cold atoms relevant to tests of the weak equivalence principle, and (ii) the Kasevich-Chu interferometer. In order to lay the foundations for this analysis we first present a representation-free description of the Kasevich-Chu interferometer based on unitary operators.

description: Collecting user data is crucial for advancing machine learning, social science, and government policies, but the privacy of the users whose data is being collected is a growing concern. {\em Differential Privacy (DP)} has emerged as the most standard notion for privacy protection with robust mathematical guarantees. Analyzing such massive amounts of data in a privacy-preserving manner motivates the need to study differentially-private algorithms that are also super-efficient.
 This thesis initiates a systematic study of differentially-private sublinear-time and sublinear-space algorithms. The contributions of this thesis are two-fold. First, we design some of the first differentially private sublinear algorithms for many fundamental problems. Second, we develop general DP techniques for designing differentially-private sublinear algorithms.
 We give the first DP sublinear algorithm for clustering by generalizing a subsampling framework from the non-DP sublinear-time literature. We give the first DP sublinear algorithm for estimating the maximum matching size. Our DP sublinear algorithm for estimating the average degree of the graph achieves a better approximation than previous works. We give the first DP algorithm for releasing $L_2$-heavy hitters in the sliding window model and a pure $L_1$-heavy hitter algorithm in the same model, which improves upon previous works.
 We develop general techniques that address the challenges of designing sublinear DP algorithms. First, we introduce the concept of Coupled Global Sensitivity (CGS). Intuitively, the CGS of a randomized algorithm generalizes the classical notion of global sensitivity of a function, by considering a coupling of the random coins of the algorithm when run on neighboring inputs. We show that one can achieve pure DP by adding Laplace noise proportional to the CGS of an algorithm. Second, we give a black box DP transformation for a specific class of approximation algorithms. We show that such algorithms can be made differentially private without sacrificing accuracy, as long as the function has small global sensitivity. In particular, this transformation gives rise to sublinear DP algorithms for many problems, including triangle counting, the weight of the minimum spanning tree, and norm estimation.
