description: A novel method of gender Classification from fingerprint is proposed based on discrete wavelet transform (DWT) and singular value decomposition (SVD). The classification is achieved by extracting the energy computed from all the sub-bands of DWT combined with the spatial features of non-zero singular values obtained from the SVD of fingerprint images. K nearest neighbor (KNN) used as a classifier. This method is experimented with the internal database of 3570 fingerprints finger prints in which 1980 were male fingerprints and 1590 were female fingerprints. Finger-wise gender classification is achieved which is 94.32% for the left hand little fingers of female persons and 95.46% for the left hand index finger of male persons. Gender classification for any finger of male persons tested is attained as 91.67% and 84.69% for female persons respectively. Overall classification rate is 88.28% has been achieved.

title: Indemnification and the building of Canadian pipelines
Creators: name: DeVries, Megan
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: The Canadian Federal Government’s purchase of the Trans Mountain pipeline in 2018 was seen
 by many as a singular action to support the pipeline industry. However, this research will
 contend that this is not the case because this thesis will show that the federal government has
 indemnified the oil and gas pipeline industry in Canada over the past 60 years. This will be
 shown by focusing on three large-scale positive examples of Federal Government
 indemnification, they are the modern Trans Mountain pipeline expansion, the 1970’s building of
 Line 9 and the initial construction of the TransCanada pipeline project in the 1950’s. All of these
 cases relied on direct government fiscal and political support to indemnify the projects so that
 they could obtain financing and eventually be constructed. By using process tracing this thesis
 shows how the Canadian federal government has in essence been indemnifying all large-scale
 pipeline projects throughout a large part of Canada’s history. Explanations for why this
 support has existed are then explored through a lens of industry structure, and the thesis posits
 that the pipeline industry’s structure (using the metric of industry size, firm size, profit rate,
 market concentration and geographical dispersion) is one explanatory factor as to why this policy
 of indemnification has existed in Canada for such a long period of time.

Some particular solutions that lead to cyclic Hubble parameters are analyzed, where the corresponding gravitational actions are reconstructed by using several techniques and auxiliary fields. Its comparison with standard $F(R)$ gravity is performed. In addition, the so-called Little Rip, a stage of the universe evolution when some bounded systems may be dissolute, is also studied in this frame of theories.

description: Changes in the structure of agriculture and income distribution among producers make parity prices obsolete indicators of farmer well-being. This report chronicles the history of parity, surveys critiques of parity, and discusses changes that might reduce price distortions resulting from the use of the parity concept. Possible changes include adjusting the parity price formula by redefining base period prices and treating interest and taxes differently. New standards of equity, including cost of production, marginal social cost, and parity income, are examined.

description: We present results from a spectroscopic survey of the dwarf spheroidal And XXII and the two extended clusters EC1 and EC2. These three objects are candidate satellites of the Triangulum galaxy, M33, which itself is likely a satellite of M31. We use the DEep Imaging Multi-Object Spectrograph mounted on the Keck-II telescope to derive radial velocities for candidate member stars of these objects and thereby identify the stars that are most likely actual members. Eleven most probable stellar members (of 13 candidates) are found for AndXXII. We obtain an upper limit of sigma_v < 6.0 km s-1 for the velocity dispersion of AndXXII, [Fe/H] ~ -1.6 for its metallicity, and 255pc for the Plummer radius of its projected density profile. We construct a colour magnitude diagram for AndXXII and identify both the red giant branch and the horizontal branch. The position of the latter is used to derive a heliocentric distance to And XXII of 853 pm 26 kpc. The combination of the radial velocity, distance, and angular position of AndXXII indicates that it is a strong candidate for being the first known satellite of M33 and one of the very few examples of a galactic satellite of a satellite. N-body simulations imply that this conclusion is unchanged even if M31 and M33 had a strong encounter in the past few Gyr. We test the hypothesis that the extended clusters highlight tidally stripped galaxies by searching for an excess cloud of halo-like stars in their vicinity. We find such a cloud for the case of EC1 but not EC2. The three objects imply a dynamical mass for M33 that is consistent with previous estimates.

A Secure PLAN (Extended Version)

Subjects: Computer science

description: Active networks promise greater flexibility than current networks, but threaten safety and security by virtue of their programmability. We describe the design and implementation of a security architecture for the active network PLANet (Hicks et al., 1999). Security is obtained with a two-level architecture that combines a functionally restricted packet language, PLAN (Hicks et al., 1998), with an environment of general-purpose service routines governed by trust management (Blaze et al., 1996). In particular, we employ a technique which expands or contracts a packet's service environment based on its level of privilege, termed namespace-based security. As an application of our security architecture, we present the design and implementation of an active-network firewall. We find that the addition of the firewall imposes an approximately 34% latency overhead and as little as a 6.7% space overhead to incoming packets.
Power allocation schemes for cooperative communication system using weighted sum approach
Creators: name: Devarajan, Rajiv
Publisher: name: University of British Columbia
Year: 2011

description: This thesis investigates power allocation schemes for an amplify-and-forward dual-hop relay based cooperative communication system with perfect and imperfect channel state information (CSI). We define cost functions and propose power allocation schemes such that the cost functions are minimized. We analyze a multiuser system, where we select the best user for transmission, who incurs the least cost of transmission. In a practical system, estimated CSI is often imperfect. We assume the estimated CSI is affected by estimation errors, which are modeled as zero mean complex Gaussian. First we propose an optimization scheme where the objective is to minimize the weighted sum of source and relay powers. Then we propose a more general multi-objective optimization scheme which jointly optimizes sum power and signal-to-noise ratio (SNR). In our proposed schemes, source and relay nodes share a fixed total power, and transmission is allowed only if the minimum required SNR at the destination can be achieved with the available power budget. These schemes are analyzed under both perfect and imperfect CSI assumptions. In addition to proving the convexity of these problems, we propose analytical solutions for sum power minimization and SNR maximization schemes in the presence of imperfect CSI. Performance of the systems under the proposed schemes are investigated in terms of energy efficiency, throughput and outage. Simulation results show that proposed schemes reduce wastage of power by avoiding unsuccessful transmissions.

description: The XXXI European Symposium on Occultation Projects will be celebrated in ICRANet center of Pescara from 24 to 27 August 2012 (www.icranet.org/clavius2012). The occasion is the fourth centennial of the Jesuit astronomer Christopher Clavius (Bamberg 1538- Napoli 1612). The hybrid eclipse witnessed by Clavius in Rome (1567) and published on his Commentarius on the Sphere (1581 edition) was the first account of an annular eclipse ever published in a scientific book. To account of this eclipse a larger solar diameter for 1567 has to be considered, and the scientific debate is still open. This is the trait-d'union between Clavius and ESOP annual meeting. The city of Pescara and the region of Abruzzo are presented with an historical, climatic, religious and gastronomical outline.

description: The local effect of the Josephson vortices on the vortex lattice melting process in \BSCCO crystals in the presence of an in-plane field $H_{ab}$ is studied by differential magneto-optical imaging. The melting process is found to commence along the Josephson vortex stacks, forming a mesomorphic phase of periodic liquid and solid lamellas, the direction and spacing of which are controlled by $H_{ab}$. The reduction of the local melting field $H_m$ along the Josephson vortex stacks is more than an order of magnitude larger than the reduction of the average bulk $H_m$ by $H_{ab}$.

description: Grid cells in the entorhinal cortex are a central component of the brain’s spatial navigation circuit. They are largely thought to support the continuous tracking of one’s position in space by integrating self-motion cues, a function called path integration. Analyzing the putative firing of grid cells (i.e., grid-cell-like representations) in human neuroimaging data, however, is a non-trivial endeavor, given the methodological complexity and the absence of standard software tools for this analysis. In Project A of this thesis, we therefore developed the Grid Code Analysis Toolbox (GridCAT), a MATLAB-based open-source software for the automated analysis of human grid-cell-like representations in functional magnetic resonance imaging (fMRI) signals, and made this software openly available to the neuroscience community. In Project B of this thesis, we then applied the GridCAT to fMRI data from young and older adults, in order to investigate age-related changes in grid-cell-like representations. We found that grid-cell-like representations in the entorhinal cortex were compromised in old age, and this effect was mainly driven by a reduced stability of grid orientations over time. Building on this finding, in Project C we then investigated whether compromised grid-cell-like representations might be associated with path integration deficits in old age. Indeed, we found that individual magnitudes of grid-cell-like representations were predictive of age-related deficits in a behavioral path integration task, in which participants had to navigate based on integrating body-based or visual self-motion cues. On the one hand, these findings demonstrate that compromised grid-cell-like representations might be a key mechanism to explain reduced path integration performance in old age. On the other hand, however, it remained to be determined whether and to what extent other sources of error might also contribute to path integration errors in young and older adults. To address this, in Project D we used a computational modeling approach in order to decompose path integration errors into distinct causes that can corrupt path integration computations. We identified internal noise in path integration computations and a biased gain in estimating the speed of self-motion as the main error sources across both young and older adults, with an increase in internal noise accounting for the majority of age-related path integration deficits. Together, the work in this thesis not only advances our understanding of the specific contributors to path integration error, it also helps elucidate the mechanisms that underlie age-related decline in navigational functions.

We assume a WIMP mass $m_χ\sim \mathcal{O}(1-100)$ GeV and a constant splitting between successive states $δ\sim\mathcal{O}(1 - 100)$ keV. For the spin-independent scattering scenario we find that the direct experiments CDMS and XENON strongly constrain most of the DAMA/LIBRA preferred parameter space, while for WIMPs that interact with nuclei via their magnetic moment a region of parameter space corresponding to $m_χ\sim 11 $ GeV and $δ< 15$ keV is allowed by all the present direct detection constraints.

Evolution of active and polar photospheric magnetic fields during the rise of Cycle 24 compared to previous cycles

description: The evolution of the photospheric magnetic field during the declining phase and minimum of Cycle 23 and the recent rise of Cycle 24 are compared with the behavior during previous cycles. We used longitudinal full-disk magnetograms from the NSO's three magnetographs at Kitt Peak, the Synoptic Optical Long-term Investigations of the Sun (SOLIS) Vector Spectro-Magnetograph (VSM), the Spectromagnetograph and the 512-Channel Magnetograph instruments, and longitudinal full-disk magnetograms from the Mt. Wilson 150-foot tower. We analyzed 37 years of observations from these two observatories that have been observing daily, weather permitting, since 1974, offering an opportunity to study the evolving relationship between the active region and polar fields in some detail over several solar cycles. It is found that the annual averages of a proxy for the active region poloidal magnetic field strength, the magnetic field strength of the high-latitude poleward streams, and the time derivative of the polar field strength are all well correlated in each hemisphere. These results are based on statistically significant cyclical patterns in the active region fields and are consistent with the Babcock-Leighton phenomenological model for the solar activity cycle. There was more hemispheric asymmetry in the activity level, as measured by total and maximum active region flux, during late Cycle 23 (after around 2004), when the southern hemisphere was more active, and Cycle 24 up to the present, when the northern hemisphere has been more active, than at any other time since 1974. The active region net proxy poloidal fields effectively disappeared in both hemispheres around 2004, and the polar fields did not become significantly stronger after this time. We see evidence that the process of Cycle 24 field reversal has begun at both poles.

description: The coupling of scale-free networks with mobile unstructured networks is certainly unusual. In mobile networks, connections active at a given instant are constrained by the geographical distribution of mobile nodes, and by the limited signal strength of the wireless technology employed to build the ad-hoc overlay. This is in contrast with the presence of hubs, typical of scale-free nets. However, opportunistic (mobile) networks possess the distinctive feature to be delay tolerant; mobile nodes implement a store, carry and forward strategy that permits to disseminate data based on a multi-hop route, which is built in time, when nodes encounter other ones while moving. In this paper, we consider opportunistic networks as evolving graphs where links represent contacts among nodes arising during a (non-instantaneous) time interval. We discuss a strategy to control the way nodes manage contacts and build "opportunistic overlays". Based on such an approach, interesting overlays can be obtained, shaped following given desired topologies, such as scale-free ones.

description: We have developed a novel all-optical broadband scheme for exciting, amplifying and measuring the secular motion of ions in a radio frequency trap. Oscillation induced by optical excitation has been coherently amplified to precisely control and measure the ion's secular motion. Requiring only laser line-of-sight, we have shown that the ion's oscillation amplitude can be precisely controlled. Our excitation scheme can generate coherent motion which is robust against variations in the secular frequency. Therefore, our scheme is ideal to excite the desired level of oscillatory motion under conditions where the secular frequency is evolving in time. Measuring the oscillation amplitude through Doppler velocimetry, we have characterized the experimental parameters and compared them with a molecular dynamics simulation which provides a complete description of the system.

Gleichzeitig agierten die lokalen Eliten mit vergleichbaren Mitteln wie der Princeps selbst. So hatten sie zahlreiche Ämter inne und präsentierten sich als fürsorgliche und spendable Euergeten, was ihre herausragende Rolle – ähnlich wie die des Kaisers – legitimieren sollte.

For this purpose the Lifshitz-type formulas adapted for the case of cylindrical geometry with the help of the proximity force approximation are used. The results obtained are compared with those derived from the hydrodymanic model of graphene. Numerical computations are performed for hydrogen atoms and molecules. It is shown that the Dirac model leads to larger values of the van der Waals force than the hydrodynamic model. For a hydrogen molecule the interaction energy and force computed using both models are larger than for a hydrogen atom.

The Concept of Philanthropy in the Early Syrian Fathers

Publisher: name: Columbia University

History

description: Philanthropy implies love of humankind and the wish to improve the welfare of one’s neighbor, often through charitable deeds or donations. The philanthropic mission therefore also implies relatedness, because it depends on a setting in which the needs of fellow beings are discerned and met. The understanding that philanthropy and communal existence are intimately linked is at the heart of this article.
Given the close association of philanthropic work and interrelatedness, a discussion of the former notion within the context of Oriental Christianity may, at first sight, appear a rather hopeless enterprise, especially if considering the more extreme manifestations of early Syrian ascetical practices , which are reported in historical source. Passages from texts, such as Theodoret of Cyrrhus’ History of the Monks of Syria, Palladius’ Historia Lausiaca, or Sozomen’s Church History, conjure up the image of Syrain ascetics living in remote, isolated areas, untouched by civilization.

However, usually this contribution is ignored by assuming a diagonal mass matrix for charged leptons. In this letter we test this common assumption in the context of neutrino physics. Our analytical and numerical results for two supersymmetric models reveal that such a simplification is not justified. Especially for the solar and reactor mixing angles important modifications are found.

description: Magnetotransport and superconducting properties are investigated for uniformly La-doped SrTiO3 films and GdTiO3/SrTiO3 heterostructures, respectively. GdTiO3/SrTiO3 interfaces exhibit a high-density two-dimensional electron gas on the SrTiO3-side of the interface, while for the SrTiO3 films carriers are provided by the dopant atoms. Both types of samples exhibit ferromagnetism at low temperatures, as evidenced by a hysteresis in the magnetoresistance. For the uniformly doped SrTiO3 films, the Curie temperature is found to increase with doping and to coexist with superconductivity for carrier concentrations on the high-density side of the superconducting dome. The Curie temperature of the GdTiO3/SrTiO3 heterostructures scales with the thickness of the SrTiO3 quantum well. The results are used to construct a stability diagram for the ferromagnetic and superconducting phases of SrTiO3.

description: No matter how robust the employed security mechanisms are malicious users or attackers will always find a way to bypass them. In addition, National Institute of Security and Technology mentions "In conjunction with appropriate tools and procedures, audit trail can assist in detecting security violation and flaws in applications". Until now, in Multimedia Communication Services (MCS), such as Voice over IP, audit trails are not utilized in security audits due to (a) the lack of the appropriate analysis tools and (b) privacy restrictions. In this paper we report on the analysis of MCS audit trail by employing a novel method for identifying "uncommon" traffic indicating non normal behaviour that does not violate users' privacy. We rely on entropy theory and the notion of "itself information" to quantify the randomness of specific message segments, and we also introduce the term "actual itself information" for the assessment of entire message randomness. To protect users' privacy we hash audit trail's data. For evaluating the applicability of our proposed method we utilize an audit trail of a real MCS provider published by honey pot project. Initial outcomes show the feasibility of employing such a method to recognize "uncommon" traffic, recorded in MCS audit trail.

description: One approach to speaker adaptation for the neural-network acoustic models of a hybrid connectionist-HMM speech recognizer is to adapt a speaker-independent network by performing a small amount of additional training using data from the target speaker, giving an acoustic model specifically tuned to that speaker. This adapted model might be useful for speaker recognition too, especially since state-of-the-art speaker recognition typically performs a speech-recognition labelling of the input speech as a first stage. However, in order to exploit the discriminant nature of the neural nets, it is better to train a single model to discriminate both between the different phone classes (as in conventional speech recognition) and between the target speaker and the 'rest of the world' (a common approach to speaker recognition). We present the results of using such an approach for a set of 12 speakers selected from the DARPA/NIST Broadcast News corpus. The speaker-adapted nets showed a 17% relative improvement in worderror rate on their target speakers, and were able to identify among the 12 speakers with an average equal-error rate of 6.6%.

description: We study the electronic transport through a noncollinear single-electron spin-valve transistor. It consists of a small metallic island weakly coupled to two ferromagnetic leads with noncollinear magnetization directions. The electric current is influenced by Coulomb charging and by spin accumulation. Furthermore, the interplay of Coulomb interaction and tunnel coupling to spin-polarized leads yields a many-body exchange field, in which the accumulated island spin precesses. We analyze the effects of this exchange field in both the linear and nonlinear transport regime. In particular, we find that the exchange field can give rise to a high sensitivity of the island's spin orientation on the gate voltage.

description: Während die Res Gestae als wichtige Quelle für Leben und Werk des Augustus verstanden werden, stellt Henning Ohst [„Irasci me tibi scito“. Augustus und sein Verhältnis zu Horaz im Spiegel der Fragmente seiner Privatkorrespondenz] Briefe des Princeps vor. Diese sind nur fragmentarisch und durch andere Autoren überliefert, bieten der Forschung noch immer Möglichkeiten zu neuen Fragestellungen. Im Fokus des Beitrages steht die Beziehung des Princeps zu Dichtern wie Vergil. Ohst stellt sich die Frage, wodurch die antiken Autoren deutlich machen, dass es sich um Zitate handelt, und welche Rolle die Zitate in den entsprechenden Texten. Einerseits handelt es sich um authentische Zeugnisse des Augustus, andererseits müssen sie auf ihren Zweck für das jeweilige Werk hin analysiert werden.

description: In this paper we present a general probabilistic model suitable for transcribing single-channel audio recordings containing multiple polyphonic sources. Our system requires no prior knowledge of the instruments in the mixture, although it can benefit from this information if available. In contrast to many existing polyphonic transcription systems, our approach explicitly models the individual instruments and is thereby able to assign detected notes to their respective sources. We use a set of training instruments to learn a model space which is then used during transcription to constrain the properties of models fit to the target mixture. In addition, we encourage model sparsity using a simple approach related to tempering. We evaluate our method on both recorded and synthesized two-instrument mixtures, obtaining average frame-level F-measures of up to 0.60 for synthesized audio and 0.53 for recorded audio. If knowledge of the instrument types in the mixture is available, we can increase these measures to 0.68 and 0.58, respectively, by initializing the model with parameters from similar instruments.
Improving the run-time and memory scalability of FPGA CAD algorithms

description: Field-Programmable Gate Arrays (FPGAs) are pre-fabricated integrated circuits that can be configured as any digital system. Configuration is done by Computer-Aided Design (CAD) tools. The demand placed on these tools continues to grow as advances in process technology continue to allow for more complex FPGAs. Already, for large designs, compile-times of an entire work day are common and memory requirements that exceed what would be found in a typical workstation are the norm. This thesis presents three contributions toward improving FPGA CAD tool scalability. First we derive an analytical model that relates key FPGA architectural parameters to the CAD place-and-route (P&R) run-times. Validation shows that the model can accurately capture the trends in run-time when architecture parameters are changed. Next we focus on the CAD tool’s storage requirements. A significant portion of memory usage is in representing the FPGA. We propose a novel scheme for this representation that reduces memory usage by 5x-13x at the expense of a 2.26x increase in routing run-time. Storage is also required to track metrics used during routing. We propose three simple memory management schemes for this component that further reduces memory usage by 24%, 34%, and 43% while incurring a routing run-time increase of 4.5%, 6.5%, and 144% respectively. We also propose a design-adaptive scheme that reduces memory usage by 41% while increasing routing run-time by only 10.4%. Finally, we focus on the issue of long CAD run-times by investigating the design of FPGA architectures amenable to fast CAD. Specifically, we investigate the CAD run-time and area/delay trade-offs when using high-capacity logic blocks (LBs). Two LB architectures are studied: traditional and multi-level. Results show that for the considered architectures, CAD run-time can be reduced at the expense of area; speed improved. For example, CAD run-time could be reduced by 25% with an area increase of 5%. We also show that the run-time trade-offs through these architectural changes can be complementary with many previously published algorithmic speed-ups.

description: We describe an experiment in superconductivity suitable for an advanced undergraduate laboratory. Point-contact spectroscopy is performed by measuring the differential conductance between an electrochemically etched gold tip and a 100-nm superconducting niobium film with a transition temperature Tc ~= 7 K. By fitting the results to Blonder-Tinkham-Klapwijk theory using a finite lifetime of quasiparticles, we obtain a superconducting gap energy δ~= 1.53 meV, a lower bound to the Fermi velocity vF >= 3.1 x 10^-7 cm/s, and a BCS coherence length ζ~= 43 nm for niobium. These results are in good agreement with previous measurements.

description: In statistical mechanics, the Potts model is a model for interacting spins with more than two discrete states. Neural networks which exhibit features of learning and associative memory can also be modeled by a system of Potts spins. A spontaneous behavior of hopping from one discrete attractor state to another (referred to as latching) has been proposed to be associated with higher cognitive functions. Here we propose a model in which both the stochastic dynamics of Potts models and an adaptive potential function are present. A latching dynamics is observed in a limited region of the noise(temperature)-adaptation parameter space. We hence suggest noise as a fundamental factor in such alternations alongside adaptation. From a dynamical systems point of view, the noise-adaptation alternations may be the underlying mechanism for multi-stability in attractor based models. An optimality criterion for realistic models is finally inferred.

description: Protection against Denial of Service (DoS) attacks is a challenging and ongoing problem. Current overlay-based solutions can transparently filter unauthorized traffic based on user authentication. Such solutions require either pre-established trust or explicit user interaction to operate, which can be circumvented by determined attackers and is not always feasible (e.g., when user interaction is impossible or undesirable). We propose a Multi-layer Overlay Network (MON) architecture that does not depend on user authentication, but instead utilizes two mechanisms to provide DoS resistant to any IP-based service, and operates on top of the existing network infrastructure. First, MON implements a threshold-based intrusion detection mechanism in a distributed fashion to mitigate DoS close to the attack source. Second, it randomly distributes user packets amongst different paths to probabilistically increase service availability during an attack. We evaluate MON using the Apache web server as a protected service. Results demonstrate MON nodes introduce very small overhead, while users' service access time increases by a factor of 1.1 to 1.7, depending on the configuration. Under an attack scenario MON can decrease the attack traffic forwarded to the service by up to 85%. We believe our work makes the use of overlays for DoS protection more practical relative to prior work.
