description: Performing a live digital forensics investigation on a running system is challenging due to the time pressure under which decisions have to be made. Newly proliferating and frequently applied types of malware (e.g., fileless malware) increase the need to conduct digital forensic investigations in real-time. In the course of these investigations, forensic experts are confronted with a wide range of different forensic tools. The decision, which of those are suitable for the current situation, is often based on the cyber forensics experts' experience. Currently, there is no reliable automated solution to support this decision-making. Therefore, we derive requirements for visually supporting the decision-making process for live forensic investigations and introduce a research prototype that provides visual guidance for cyber forensic experts during a live digital forensics investigation. Our prototype collects relevant core information for live digital forensics and provides visual representations for connections between occurring events, developments over time, and detailed information on specific events. To show the applicability of our approach, we analyze an exemplary use case using the prototype and demonstrate the support through our approach.

Calibration of orifice meters at low Reynolds numbers
Creators: name: Swain, Frederick Clifford
Publisher: name: University of British Columbia
Year: 2011

description: Seventeen square-edged orifice plates were calibrated to study the effect of varying throat length, both in the absence and in the presence of geometrical similarity, on the coefficient of discharge for pipe Reynolds numbers from 20 to1 10,000. The experiments involved the use of hydraulically smooth pipe in test lines of 1 - inch, 1.5 - inch and 2 - inch nominal I.D., corner pressure taps and Beta ratios (orifice diameter/pipe diameter) of 0.2, 0.4 and 0.6. Six of the plates were built using design criteria recommended by the A.S.M.E. in "Fluid Meters" (1), and with Beta ratios specified at 0.4. Each test line was used with two plates, which were identical except for a variation in throat length within the range of the given design recommendations. A comparison of discharge coefficients as a function of pipe Reynolds number indicated the following: (1) Reynolds numbers 30 - 3,000. Consistent differences of 2-6% were observed in the calibration curves due to the variation in throat length allowed by "Fluid Meters".(1). (2) Reynolds number 3,000 - 10,000. Geometry appeared to be much less important, as all calibration curves tended to coincide. Two further plates, for the 1.5 - inch pipe only, were built using the A.S.M.E. "Power Test Code" (2) as a design reference. They were designed to have respectively the minimum and maximum throat length allowable under the code. The results, when plotted, indicated that in a pipe Reynolds number range of 40 - 1,500, plates built identically except for small differences in throat length, still gave distinguishably different calibration curves. The remaining nine plates were divided into three groups of three plates each, encompassing the three pipe diameters and three Beta ratios. All plates within a group were geometrically similar. The results, for pipe Reynolds numbers from 20 to 2,000, indicated that a total specification of orifice shape gave consistent calibration curves with no apparent absolute size effects. Thus, both "Fluid Meters" *and the "Power Test Code" recommended design criteria for standard orifice plates which do not completely take into account the effect of geometry on the coefficient of discharge at low Reynolds numbers. In particular, the tolerances allowed on throat length are too large.
Covariant Light-Front Approach for $B_c$ transition form factors

description: In the covariant light-front quark model, we investigate the form factors of $B_c$ decays into $D, D^*, D_s, D_s^*, η_c, J/ψ, B, B^*, B_s, B_s^*$ mesons. The form factors in the spacelike region $q^2<0$ are directly evaluated. To extrapolate the form factors to the full kinematic region, we fit the form factors by adopting a three-parameter form from the spacelike region. $b\to u,d,s$ transition form factors at maximally recoiling point ($q^2=0$) are smaller than $b\to c$ and $c\to d,s$ transition form factors, while the $b\to d,s,c$ form factors at zero recoiling point are close to each other. In the fitting procedure, we find the parameters for the form factors $A_2(B_c\to B^*)$ and $A_2(B_c\to B^*_s)$ strongly depend on the decay constants of $B^*$ and $B_s^*$ mesons. Fortunately, the semileptonic and nonleptonic $B_c$ decays are not sensitive to these form factors. With the form factors, we also investigate the branching fractions, polarizations of the semileptonic $B_c\to Mlν$ decays. Semileptonic $B_c\to (η_c,J/ψ)lν$ and $B_c\to (B_s,B_s^*)lν$ decays have much larger branching fractions than $B_c\to (D,D^*,B,B^*)lν$. In the three kinds of $B_c\to Vlν$ decays, contributions from the longitudinal polarized vector is comparable with those from the transversely polarized vector. These predictions will be tested at the ongoing and forthcoming hadron colliders.

description: This paper concerns the reconstruction of the absorption and scattering parameters in a time-dependent linear transport equation from knowledge of angularly averaged measurements performed at the boundary of a domain of interest. We show that the absorption coefficient and the spatial component of the scattering coefficient are uniquely determined by such measurements. We obtain stability results on the reconstruction of the absorption and scattering parameters with respect to the measured albedo operator. The stability results are obtained by a precise decomposition of the measurements into components with different singular behavior in the time domain.

description: Based on the recent paper (Phys. Rev. Lett. 102, 216803, (2009)), we study the nonequilibrium occupation number and charge susceptibility of a resonance level close to a dissipative quantum phase transition of the Kosterlitz-Thouless (KT) type between a de-localized phase for weak dissipation and a localized phase for strong dissipation. The resonance level is coupled to two spinless fermionic baths with a finite bias voltage and an Ohmic bosonic bath representing the dissipative environment. The system is equivalent to an effective anisotropic Kondo model out of equilibrium. Within the nonequilibrium Renormalization Group (RG) approach, we calculate nonequilibrium magnetization and spin susceptibility in the effective Kondo model, corresponding to occupation number and charge susceptibility of a resonance level, respectively. We demonstrate the smearing of the KT transition in the nonequilibrium magnetization as a function of the effective anisotropic Kondo couplings, in contrast to a perfect jump in magnetization at the transition in equilibrium. In the limit of large bias voltages, we find both quantities at the KT transition and in the localized phase show deviations from the equilibrium Curie-law behavior. As the system gets deeper in the localized phase, both quantities decrease more rapidly to zero with increasing bias voltages.

description: We present a Differential Emission Measure (DEM) analysis of the quiet solar corona on disk using data obtained by the Extreme-ultraviolet Imaging Spectrometer (EIS) on {\it Hinode}. We show that the expected quiet Sun DEM distribution can be recovered from judiciously selected lines, and that their average intensities can be reproduced to within 30%. We present a subset of these selected lines spanning the temperature range $\log$ T = 5.6 to 6.4 K that can be used to derive the DEM distribution reliably. The subset can be used without the need for extensive measurements and the observed intensities can be reproduced to within the estimated uncertainty in the pre-launch calibration of EIS. Furthermore, using this subset, we also demonstrate that the quiet coronal DEM distribution can be recovered on size scales down to the spatial resolution of the instrument (1$"$ pixels). The subset will therefore be useful for studies of small-scale spatial inhomogeneities in the coronal temperature structure, for example, in addition to studies requiring multiple DEM derivations in space or time. We apply the subset to 45 quiet Sun datasets taken in the period 2007 January to April, and show that although the absolute magnitude of the coronal DEM may scale with the amount of released energy, the shape of the distribution is very similar up to at least $\log$ T $\sim$ 6.2 K in all cases. This result is consistent with the view that the {\it shape} of the quiet Sun DEM is mainly a function of the radiating and conducting properties of the plasma and is fairly insensitive to the location and rate of energy deposition. This {\it universal} DEM may be sensitive to other factors such as loop geometry, flows, and the heating mechanism, but if so they cannot vary significantly from quiet Sun region to region.

description: We investigate the optimal design of networks for a general transport system. Our network is built from a regular two-dimensional ($d=2$) square lattice to be improved by adding long-range connections (shortcuts) with probability $P_{ij} \sim r_{ij}^{-α}$, where $r_{ij}$ is the Euclidean distance between sites $i$ and $j$, and $α$ is a variable exponent. We introduce a cost constraint on the total length of the additional links and find optimal transport in the system for $α=d+1$. Remarkably, this condition remains optimal, regardless of the strategy used for navigation, being based on local or global knowledge of the network structure, in sharp contrast with the results obtained for unconstrained navigation using global or local information, where the optimal conditions are $α=0$ and $α=d$, respectively. The validity of our theoretical results is supported by data on the US airport network, for which $α\approx 3.0$ was recently found [Bianconi {\it et al.}, arXiv:0810.4412 (2008)].

description: We study the metal-insulator transition in a tight-binding one-dimensional (1D) model with long-range correlated disorder. In the case of diagonal disorder with site energy within $[-\frac{W}{2},\frac{W}{2}]$ and having a power-law spectral density $S(k)\propto k^{-α}$, we investigate the competition between the disorder and correlation. Using the transfer-matrix method and finite-size scaling analysis, we find out that there is a finite range of extended eigenstates for $α>2$, and the mobility edges are at $\pm E_{c}=\pm|2-W/2|$. Furthermore, we find the critical exponent $ν$ of localization length ($ξ\sim |E-E_{c}|^{-ν}$) to be $ν=1+1.4e^{2-α}$. Thus our results indicate that the disorder strength $W$ determines the mobility edges and the degree of correlation $α$ determines the critical exponents.

description: Apart from the 11-year solar cycle, another periodicity around 155-160 days was discovered during solar cycle 21 in high energy solar flares, and its presence in sunspot areas and strong magnetic flux has been also reported. This periodicity has an elusive and enigmatic character, since it usually appears only near the maxima of solar cycles, and seems to be related with a periodic emergence of strong magnetic flux at the solar surface. Therefore, it is probably connected with the tachocline, a thin layer located near the base of the solar convection zone, where strong dynamo magnetic field is stored. We study the dynamics of Rossby waves in the tachocline in the presence of a toroidal magnetic field and latitudinal differential rotation. Our analysis shows that the magnetic Rossby waves are generally unstable and that the growth rates are sensitive to the magnetic field strength and to the latitudinal differential rotation parameters. Variation of the differential rotation and the magnetic field strength throughout the solar cycle enhance the growth rate of a particular harmonic in the upper part of the tachocline around the maximum of the solar cycle. This harmonic is symmetric with respect to the equator and has a period of 155-160 days. A rapid increase of the wave amplitude could give place to a magnetic flux emergence leading to observed periodicities in solar activity indicators related with magnetic flux.

Vähidiagnoos mõjutab tugevalt nii inimese elu üldiselt kui ka tema hinnanguid elukvaliteedile.  Eesmärk. Selgitada välja vähipatsientide hinnangud oma elukvaliteedile ja seda mõjutavad tegurid Eestis.  Metoodika. Uuringu sihtrühmaks olid kõik Eestis elavad vähidiagnoosi saanud inimesed, kellele jagasid küsimustikke onkoloogiaosakonnad ja vähiliit ning kes kutsuti meedia kaudu üles täitma küsimustikku ka internetis.

Vähipatsientide küsitluse tulemuste põhjal mõjutas vähihaigete hinnanguid elukvaliteedile kõige enam füüsiline tervis ja uuritavate hinnangud olid füüsilisele tervisele kehvemad kui teistele elukvaliteeti mõjutavatele teguritele. Kõige paremad olid hinnangud sotsiaalsetele suhetele. Vähihaigete hinnanguid elukvaliteedile mõjutavad ka isiklikud uskumused ning sotsiaal-majanduslikud näitajad nagu haridustase ja tööturustaatus.  Järeldused. Vähidiagnoosiga inimeste hinnanguid elukvaliteedile mõjutab kõige enam nende füüsiline tervis – kaasuvate haiguste olemasolu, aktiivse ravi kestus, füüsilised vaevused jms. Samas võivad hinnangud varieeruda ka haridustasemest, tööturustaatusest, isiklikest uskumustest ja soost lähtudes.Eesti Arst 2014; 93(1):15–22

description: A novel approach for recognition of handwritten compound Bangla characters, along with the Basic characters of Bangla alphabet, is presented here. Compared to English like Roman script, one of the major stumbling blocks in Optical Character Recognition (OCR) of handwritten Bangla script is the large number of complex shaped character classes of Bangla alphabet. In addition to 50 basic character classes, there are nearly 160 complex shaped compound character classes in Bangla alphabet. Dealing with such a large varieties of handwritten characters with a suitably designed feature set is a challenging problem. Uncertainty and imprecision are inherent in handwritten script. Moreover, such a large varieties of complex shaped characters, some of which have close resemblance, makes the problem of OCR of handwritten Bangla characters more difficult. Considering the complexity of the problem, the present approach makes an attempt to identify compound character classes from most frequently to less frequently occurred ones, i.e., in order of importance. This is to develop a frame work for incrementally increasing the number of learned classes of compound characters from more frequently occurred ones to less frequently occurred ones along with Basic characters. On experimentation, the technique is observed produce an average recognition rate of 79.25 after three fold cross validation of data with future scope of improvement and extension.

Gas absorption in cocurrent turbulent bubble flow
Creators: name: Lamont, John Craig
Publisher: name: University of British Columbia
Year: 2011

description: Mass transfer rates have been measured for streams of CO₂ bubbles of controlled frequency being absorbed into water in cocurrent pipeline flow. Superficial liquid Reynolds number varied from 1810 to 24000. Mass transfer coefficients based on equivalent spherical areas were between 0.6 and 4.5 cm/min. For 5/16- and 5/8 inch I.D. tubes oriented both horizontally and vertically, the mass transfer coefficients were proportional to (Reynolds number)⁰•⁵² and (tube diameter) ⁻⁰•⁸⁵ at high Reynolds number. Bubble velocities were measured for all test sections and flow conditions. Photographs of bubbles in turbulent flow were obtained by a high speed flash technique. The mass transfer results support a postulated mechanism of surface renewal by turbulent eddies which result from the mean flow of liquid through the tube. Two theoretical approaches have been described in an attempt to relate the surface renewal rate to the pipe flow turbulence. A model based on mixing length theory gives good agreement with the experimental results. In this model the larger scales of motion dominate. A second model was based on the assumption that the very small scales dominate. The flow and convective diffusion equations were solved for idealized viscous eddy cells which represent the small motions. The size, velocity and mass transfer rate of these cells were linked to the turbulent energy spectrum for both solid/liquid and gas/liquid interfaces. The predicted dependence of mass transfer coefficient on Schmidt number and energy dissipation is identical with experimental results for solid surfaces. However, the Reynolds number dependence (Re•⁶⁹) is higher than for the present experiments. Nevertheless, the eddy cell model maybe valid for bubbles and solids in sufficiently highly developed turbulence.

The fibers are arranged uniformly on the perimeter of a circle, and the linearly polarized beams of equal shape are superimposed such that the far field pattern represents an effective radially polarized vector beam, or discrete cylindrical vector (DCV) beam. The DCV beam is produced by three or more beams that each individually have a varying polarization vector. The beams are appropriately distributed in the near field such that the far field intensity distribution has a central null. This result is in contrast to the situation of parallel linearly polarized beams, where the intensity peaks on axis.

description: Idiopaatilise intrakraniaalse hüpertensiooni (IIH) sündroomi iseloomustavad intrakraniaalse rõhu tõusule iseloomulikud sümptomid, kuid selle põhjuseks ei ole koljusisest mahtu suurendavad protsessid ega hüdrotsefaalia. Sagedamini haigestuvad ülekaalulised fertiilses eas naised. Peamisteks kaebusteks on peavalu, nägemishäired ja tinnitus. Uuringul ilmnevad paispapillid, nägemisteravuse halvenemine ja vaateväljade ahenemine. Kulg on suhteliselt healoomuline, raskematel juhtudel kujunevad püsivad nägemishäired. Ravi eesmärk on leevendada vaevusi ja säilitada nägemine. Medikamentidest on kasutusel süsinikanhüdraasi inhibiitorid (atsetasolamiid) ja topiramaat. Nägemishäirete progresseerumisel on soovitatavad liikvorit šuntivad operatsioonid.Eesti Arst 2014; 93(1):36–39

The Lee Wick Standard Model

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

description: This article reviews some recent work on a version of the standard model (the Lee-Wick standard model) that contains higher derivative kinetic terms that improve the convergence of loop diagrams removing the quadratic divergence in the Higgs boson mass. Naively higher derivative theories of this type are not acceptable since the higher derivative terms either cause instabilities (from negative energies) or a loss of unitarity (from negative norm states). Lee and Wick provided an interpretation for such theories arguing that theories with higher derivative kinetic terms can be unitary and stable if the states associated with the massive propagator poles, that arise from the higher derivatives, have widths and hence decay and are not in the spectrum of the theory.

Condensation of steam in a packed column in direct contact with immiscible liquids
Creators: name: Rai, Virendra Chandra
Publisher: name: University of British Columbia
Year: 2011

description: A packed condenser and the auxiliary equipment were designed, built and tested for the condensation of steam in direct contact with Aroclor 1242 and 1248, which are commercial heat transfer agents and are immiscible with water. The co-current flow of steam and liquid, through a four inch inside diameter column packed with three-eighth inch ceramic Raschig rings, was studied. The packing heights used in the condensation of steam were estimated from the liquid temperature profile in the column. The heights of the transfer units for condensation and the average volumetric overall heat transfer coefficients were calculated. The height of the transfer unit for condensation was found to be affected largely by the mean viscosity and the flow rate of the liquid. Two empirical equations have been developed to describe the results of this study. HCU = F ( μ ) (n) where n = 1. 10 for Aroclor 1242 and n = 1. 16 for Aroclor 1248 is mean viscosity of the Aroclor in centipoise. For Aroclor 1242, F= 0.0535 + 8.90 x l0⁻⁶ L when L ≤ 2290 and F =-0. 0737 + 6. 44 x 10⁻⁵ L when L > 2290. For Aroclor 1248, F = 0. 02765 + 1. 244 x 10⁻⁵ L. L is superficial mass velocity of the Aroclor in lb /hr. ft²

description: Term extraction is one of the layers in the ontology development process which has the task to extract all the terms contained in the input document automatically. The purpose of this process is to generate list of terms that are relevant to the domain of the input document. In the literature there are many approaches, techniques and algorithms used for term extraction. In this paper we propose a new approach using particle swarm optimization techniques in order to improve the accuracy of term extraction results. We choose five features to represent the term score. The approach has been applied to the domain of religious document. We compare our term extraction method precision with TFIDF, Weirdness, GlossaryExtraction and TermExtractor. The experimental results show that our propose approach achieve better precision than those four algorithm.

description: The Young Stellar Object (YSO) W33A is one of the best known examples of a massive star still in the process of forming. Here we present Gemini North ALTAIR/NIFS laser-guide star adaptive-optics assisted K-band integral-field spectroscopy of W33A and its inner reflection nebula. In our data we make the first detections of a rotationally-flattened outer envelope and fast bi-polar jet of a massive YSO at near-infrared wavelengths. The predominant spectral features observed are Br-gamma, H_2, and a combination of emission and absorption from CO gas. We perform a 3-D spectro-astrometric analysis of the line emission, the first study of its kind. We find that the object's Br-gamma emission reveals evidence for a fast bi-polar jet on sub-milliarcsecond scales, which is aligned with the larger-scale outflow. The hybrid CO features can be explained as a combination of hot CO emission arising in a disk close to the central star, while cold CO absorption originates in the cooler outer envelope. Kinematic analysis of these features reveals that both structures are rotating, and consistent with being aligned perpendicularly to both the ionised jet and the large-scale outflow. Assuming Keplerian rotation, we find that the circumstellar disk orbits a central mass of >10Msun, while the outer envelope encloses a mass of ~15Msun. Our results suggest a scenario of a central star accreting material from a circumstellar disk at the centre of a cool extended rotating torus, while driving a fast bi-polar wind. These results therefore provide strong supporting evidence for the hypothesis that the formation mechanism for high-mass stars is qualitatively similar to that of low-mass stars.

Extinction of quasiparticle interference in underdoped cuprates with coexisting order

description: Recent scanning tunnelling spectroscopy measurements [Y. Koksaka et al., Nature 454, 1072 (2008)] have shown that dispersing quasiparticle interference peaks in Fourier transformed conductance maps disappear as the bias voltage exceeds a certain threshold corresponding to the coincidence of the contour of constant quasiparticle energy with the antiferromagnetic zone boundary. Here we argue that this is caused by quasistatic short-range coexisting order present in the d-wave superconducting phase, and that the most likely origin of this order is disorder-induced incommensurate antiferromagnetism. We show explicitly how the peaks are extinguished in the related situation with coexisting long-range antiferromagnetic order, and discuss the connection with the realistic disordered case. Since it is the localized quasiparticle interference peaks rather than the underlying antinodal states themselves which are destroyed at a critical bias, our proposal resolves a conflict between scanning tunneling spectroscopy and photoemission regarding the nature of these states.

Praeguseks on hakatud seisundit mõnikord nimetama ka depressiooni-valusündroomiks. Mõlemad sündroomid alluvad samale ravile, ägestavad teineteist, neil on sama bioloogiline substraat ja virgatsained. Praegu on depressiooni ja valu seos jälle huviorbiidis, kuna uued serotoniini, noradrenaliini ning dopamiini süsteemi toimivad antidepressandid on osutumas tõhusaks ka valusündroomide ravis.

Auditit ajendas tegema mitme osapoole arvamus, et taastusravi ei saa kaugeltki kõik vajajad, kuigi taastusravi osutamine peaks eeldatavasti parandama patsientide elukvaliteeti ning vähendama hilisemaid ravikulusid. Ka Riigikontrolli analüüs  leidis, et enamik taastusravi vajanutest on sellest ilma jäänud ning selle peamised põhjused on ressursside puudus, teenuse saamise sõltuvus elukohast ning teenuse osutamine osaliselt ka mittevajajatele.

Mathematical model for the selection of haying machinery
Creators: name: Jeffers, John Percival Weldon
Publisher: name: University of British Columbia
Year: 2011

description: Surveys of hay harvesting machinery in the Lower Fraser Valley of British Columbia indicated wide variation in sizes of machines employed on farms of comparative size. Quality hay depends on 1. the types of forages grown 2. the stage of growth at which the crop is harvested and 3. the influence of weather as it effects curing. Bleaching, leaf shatter, and leaching of soluble nutrients are the worst hazards to which the crop is exposed. The system of harvesting will affect the time the crop is exposed to the effects of the weather. Methods that reduce the time needed for curing in the field tend to produce a better quality hay. Factors affecting the selection of least cost combinations of machines used in sequence are 1. the cost which bears a linear relationship to the capacity of the machines, 2. the area they have to service and 3. the time available for the performance of the operations. The time available for a sequence of operations to be performed in this case is a function of the weather. A study of the weather of the Lower Fraser Valley indicated that in any given ten day period during the months of June, July and August, the probabilities of two or more, three or more or four or more open days for field curing hay are constant. Using this linear cost capacity relationship, acreages from ten to one hundred acres, and the time available obtained from weather probability data, a mathematical model is derived to select least cost machinery combinations for hay harvesting in the Lower Fraser Valley. A computer programme for the I.B.M. 7040 digital computer is also developed.
