description: This paper shows how to improve the real-time object detection in complex robotics applications, by exploring new visual features as AdaBoost weak classifiers. These new features are symmetric Haar filters (enforcing global horizontal and vertical symmetry) and N-connexity control points. Experimental evaluation on a car database show that the latter appear to provide the best results for the vehicle-detection problem.

description: The AMIGA project (Analysis of the interstellar Medium of Isolated GAlaxies) is an international collaboration led from the Instituto de Astrofísica de Andalucía (CSIC). The group's experience in radio astronomy databases turned, as a natural evolution, into an active participation in the development of data archives and radio astronomy software. The contributions of the group to the VO have been mostly oriented towards the deployment of large VO compliant databases and the development of access interfaces (IRAM 30m Pico Veleta, DSS-63 70m in Robledo de Chavela). We also have been working in the development of an API for VO tools that will ease access to VO registries and communication between different VO software. A collaboration with the Kapteyn Astronomical Institute has started recently in order to perform a complete renovation of the only existing high-level software (GIPSY) for the analysis of datacubes, allowing its fully integration in the VO.

Ecological and evolutionary genetics of Puffinus spp.

Publisher: name: University Of Tasmania
Year: 2023

description: Three distinct molecular genetic techniques were applied at different levels in the evolutionary hierarchy to investigate the reproductive ecology, population biology and systematics of species in the shearwater genus Puffinus, with particular emphasis on the short-tailed shearwater, P. tenuirostris, or Tasmanian muttonbird. Genetic relationships between mated pairs of adult short-tailed shearwaters and the single offspring in the nest were analysed by multilocus DNA fingerprinting. The human polycore minisatellite probe, 33.6, revealed sufficient variation in shearwater DNA to allow individualspecific identification. In addition this probe hybridised to a large minisatellite restrictionfragment derived from the female W chromosome, which allowed the identification of sex of adults and nestlings in this sexually monomorphic species. Analysis of DNA fingerprint profiles from 107 nestlings and one or both of the attendant adults in each case, in two independent studies, revealed 13 cases where a nestling was not related to one of the attendant adults. Although four of these unrelated adults could be accounted for by sampling errors, the remaining nine cases all involved the male in each nest and were more likely to have resulted from extra-pair copulations involving the attendant female and an unknown, extra-pair male. These results suggest that although short-tailed shearwaters exhibit strong pair fidelity and social monogamy, some birds are engaging in an alternative mating strategy that may substantially enhance both male and female reproductive success. Future estimates of life-time reproductive success in this species will have to allow for the small percentage of paired males that are unrelated to the nestlings that they are providing care for.
0-$π$ phase shifts in Josephson junctions as a signature for the $s_{\pm}$-wave pairing state

description: We investigate Josephson junctions with superconducting ferropnictides, both in the diffusive and ballistic limit. We focus on the proposed $s_\pm$-wave state, and find that the relative phase shift intrinsic to the $s_\pm$-wave state may provide 0-$π$ oscillations in the Josephson current. This feature can be used to discriminate this pairing state from the conventional s-wave symmetry. The 0-$π$ oscillations appear both as a function of the ratio of the interface resistances for each band and, more importantly, as a function of temperature, which greatly aids in their detection.

Digital software model of the human peripheral auditory system
Creators: name: Alexandre, Eric Ernest
Publisher: name: University of British Columbia
Year: 2011

description: A model of the human peripheral auditory system is presented which is based on the anatomical and physiological data and mathematical presentations of the principal workers in the field. The physiological data come from human cadavers and cats in vivo. Since not all sections of the ear are understood with equal certainty, not all sections of the model are presented with the same degree of confidence. The model is used as a tool in carrying out experiments relating psychological performance with the underlying mechanisms. One interesting example is the localization of the mechanism producing combination tones within the human ear. Since the model is also capable of producing combination tones with all but one nonlinearity within the model eliminated, the primary auditory neuron is shown to be the nonlinearity causing the formation of combination tones. A plausible theory for this effect is presented and compared to psychological data. The model was programmed in Fortran IV and run on the IBM 360/67. Because of better I/O and display facilities for acoustic input, it is desirable to implement the model on a smaller computer such as the PDP-12. The large amount of storage for the present model prohibits this but simplifications are suggested so as to enable the implementation. The major discrepancy between the data produced by the model and physiological data results because the neural frequency selectivity of the model is inadequate. An inhibitory scheme to sharpen the selectivity is proposed.

description: The population and evolutionary genetics of fishes of the genus Saurida from waters off northern Australia were examined. Allozyme electrophoresis was used to examine the population structuring of two species. The phylogenetic relationships of five species were investigated by sequencing sections of the mitrochondrial genome. General proteins and 18 enzymes representing 21 gene loci were initially screened to examine resolution of banding patterns and the levels of polymorphism. Taxa could be separated on the basis of banding patterns for general proteins and LDH.

description: We present promising results for visual object categorization, obtained with adaBoost using new original ?keypoints-based features?. These weak-classifiers produce a boolean response based on presence or absence in the tested image of a ?keypoint? (a kind of SURF interest point) with a descriptor sufficiently similar (i.e. within a given distance) to a reference descriptor characterizing the feature. A first experiment was conducted on a public image dataset containing lateral-viewed cars, yielding 95% recall with 95% precision on test set. Preliminary tests on a small subset of a pedestrians database also gives promising 97% recall with 92 % precision, which shows the generality of our new family of features. Moreover, analysis of the positions of adaBoost-selected keypoints show that they correspond to a specific part of the object category (such as ?wheel? or ?side skirt? in the case of lateral-cars) and thus have a ?semantic? meaning. We also made a first test on video for detecting vehicles from adaBoostselected keypoints filtered in real-time from all detected keypoints.
Constitutive modelling of fibre reinforced concrete and shotcrete
Creators: name: Vinh, TNG
Publisher: name: University Of Tasmania
Year: 2023

description: Fibre reinforced concrete and shotcrete have often been used in tunnel linings and in other applications such as industrial floors and pavements. The mixing of fibres into concrete or shotcrete can cause the material to resist the opening of cracks during failure. The design of these materials is not the same as for normally reinforced concrete, and there is not much in the way of rational design methods currently available. In relation to tunnel lining design, the phenomenon of rock mass squeeze out, or the use of rock bolts to anchor the rock base can lead to point loads on a fibre reinforced shotcrete lining. Therefore, this thesis investigates and develops the use of beam and panel tests which can be related a point load capacity to tunnel lining behaviour. The round determinate supported panel developed by Bernard (1999), is used in this manner for the evaluation of post-cracking behaviour in fibre reinforced concrete and shotcrete. Constitutive modeling of the behaviour of these panel specimens was carried out to assist in the interpretation of test results in the context of tunnel lining design. Yield line theory was then used to analyse the post-cracking behaviour of the fibre reinforced concrete and shotcrete panels to evaluate failure criteria. The cracks in round panels are always located at different positions in each panel test randomly. A probabilistic distribution function of crack position has therefore been determined using standard goodness of fit tests. The distribution function was then modelled using a Monte Carlo method to assess the effect of crack position on post-crack behaviour using yield line analysis. Experimental and numerical analyses have also been carried out to extend the experimental data and to assess the effect of thickness on the post-cracking behaviour of fibre reinforced shotcrete beams and panels. The test data from centrally loaded beam and round determinate supported panel tests was used to calibrate the numerical models. The principal outcomes of the research were successful modelling of post-crack behaviour of fibre reinforced concrete and shotcrete using yield line theory and prediction of cracking loads.

description: The transition to intermittent mean--field dynamos is studied using numerical simulations of isotropic magnetohydrodynamic turbulence driven by a helical flow. The low-Prandtl number regime is investigated by keeping the kinematic viscosity fixed while the magnetic diffusivity is varied. Just below the critical parameter value for the onset of dynamo action, a transient mean--field with low magnetic energy is observed. After the transition to a sustained dynamo, the system is shown to evolve through different types of intermittency until a large--scale coherent field with small--scale turbulent fluctuations is formed. Prior to this coherent field stage, a new type of intermittency is detected, where the magnetic field randomly alternates between phases of coherent and incoherent large--scale spatial structures. The relevance of these findings to the understanding of the physics of mean--field dynamo and the physical mechanisms behind intermittent behavior observed in stellar magnetic field variability are discussed.

Rank preservers on certain symmetry classes of tensors

description: Let U denote a finite dimensional vector space over an algebraically closed field F . In this thesis, we are concerned with rank one preservers on the r(th) symmetric product spaces r/VU and rank k preservers on the 2nd Grassmann product spaces 2/AU. The main results are as follows: (i) Let T : [formula omitted] be a rank one preserver. (a) If dim U ≥ r + 1 , then T is induced by a non-singular linear transformation on U . (This was proved by L.J. Cummings in his Ph.D. Thesis under the assumption that dim U > r + 1 and the characteristic of F is zero or greater than r .) (b) If 2 < dim U < r + 1 and the characteristic of F is zero or greater than r, then either T is induced by a non-singular linear transformation on U or [formula omitted] for some two dimensional sub-space W of U. (ii) Let [formula omitted] be a rank one preserver where r < s. If dim U ≥ s + 1 and the characteristic of F is zero or greater than s/r, then T is induced by s - r non-zero vectors of U and a non-singular linear transformation on U. (iii) Let T : [formula omitted] be a rank k preserver and char F ≠ 2. If T is non-singular or dim U = 2k or k = 2 , then T is a compound, except when dim U = 4 , in which case T may be the composite of a compound and a linear transformation induced by a correlation of the two dimensional subspaces of U.

The fractal character and induced structures of a propane/air diffusion flame
Creators: name: Li, HL
Publisher: name: University Of Tasmania
Year: 2023

description: Signal recovery techniques have been used to measure the periodic structures formed in a co-annular Propane/ Air diffusion flame due to acoustic excitation of the flow from upstream. The flow response was sensed using the quantitative schlieren technique, and consistent results were obtained on the basis of both axial and transverse optical beam deflections and appropriate analysis of signal records. The two dominant modes of response were identified as a series of alternating ring disturbances along the flow axis at the higher frequency and a series of alternating ring disturbances containing on axis disturbances of opposite sign at the lower frequency. The former mode was essentially associated with the fuel jet shear layer, whilst the latter was associated with the outer annular shear layer surrounding the air flow from the outer nozzle. The strength of disturbances was consistent with mixing fluctuations between cold fuel gas and the products of combustion. Structures induced in the outer shear layer weakened rapidly with the distance from the nozzle, indicating a relatively sudden breakup of coherent structures caused by the excitation near the nozzle. These results provide conclusive evidence that signal recovery from noise by phase reference to an acoustic excitation is an effective means of determining structures and strength of induced disturbance of diffusion flame. The fractal texture of Propane/ Air diffusion flame were obtained by analysing the fractal distribution of flame schlieren images based on the box counting method which is an efficient method used to analyse the fractal texture of diffusion flame schlieren images with a variance of approximately 0.04 in the fractal dimension. The results suggest that diffusion flames do exhibit fractal behaviour and that the value of fractal dimension are around of 2.3~2.47, which varies with the excitation and character of turbulent flow. The Power Spectrum Density (PSD) of propane/air diffusion flame has also been investigated. These observations of PSD appeared to be generally consistent with the fractal dimensions. A numerical simulation investigation into the fractal relationship between the original field and its schlieren images showed that there is no simple universal relationship between the fractal dimension of the schlieren image and that of the actual spatial field which gave rise to the image. However, it seems that the fractal dimension of the diffusion flame and its schlieren image are similar, whilst the fractal dimension of the schlieren image of a fairly homogeneous turbulent mixing field may exceed that of the field itself appreciably. Contours of differentiated images have potential for revealing any regular character in diffusion flames, the present work showing clear evidence of structures at approximately ¬¨¬±25 o to the flame axis.

The Adoption of data mining technology within accounting information systems in publicly listed companies in Jordan
Creators: name: Al-Odat, AMT
Publisher: name: University Of Tasmania
Year: 2023

description: The successful adoption of information technology (IT) and data mining (DM) requires a clear understanding of the organisational context within which technology operates, including both human and technological dimensions. The objective of this research is to investigate the implementation of and the readiness to adopt IT and DM technology within the accounting information system (AIS) in publicly listed companies in a developing nation, specifically Jordan. The relationship between managerial styles prevailing in Jordanian publicly listed companies and the managers' attitudes towards IT and DM are explored. In addition, relationships between certain demographic characteristics including gender, age, organisational experience, educational level, and span of control and managers' attitudes towards DM are explored. Furthermore, this research investigates issues that influence Jordanian publicly listed companies to adopt/not adopt DM technology, such as technological, organisational and human resource issues. Finally this research explores the relationship if any between awareness of DM technology and the intention to adopt these technology. The sample for this research was randomly drawn from a list of the publicly listed Jordanian companies. Surveys were sent to lower and middle line managers of publicly listed companies, and a small sample was then interviewed to enrich the data. Analysis of quantitative data was undertaken using SPSS. The analysis using SPSS confirmed the existence of two dimensions in Jordanian publicly listed companies, people-centred and task-centred management. Factor analysis indicated that the two dominant management styles were people and task orientated styles. Further analysis indicated that the people-centred management style has a significant positive relationship with the attitudes of managers and DM. On the other hand, the task-centred management style and demographic characteristics were found to have no statistically significant relationship with the attitudes of managers towards DM. The results also revealed that the majority of respondents indicated readiness toward accepting DM technology and that they are ready to use it. For both the existing adopters of DM technologies and non-adopters issues such as technological, organisational and human resources were significant and had played a role in the decision to, or not to utilise such technology. Finally, this research found that the awareness about DM has no statistical significant relationship with the intention to adopt DM tools. Considering the scarcity of previous literature in the research's particular context (Jordan) and its broader context (Arab and developing countries), this research will provide an original contribution concerning the effect and appropriateness of management styles and attitudes towards IT and DM on the use of modern computer technology within the context of publicly listed companies in developing countries.

description: The question whether a time series behaves as a random walk or as a station- ary process is an important and delicate problem, particularly arising in financial statistics, econometrics, and engineering. This paper studies the problem to detect sequentially that the error terms in a polynomial regression model no longer behave as a random walk but as a stationary process. We provide the asymptotic distribution theory for a monitoring procedure given by a control chart, i.e., a stopping time, which is related to a well known unit root test statistic calculated from sequentially updated residuals. We provide a functional central limit theorem for the corresponding stochastic process which implies a central limit theorem for the control chart. The finite sample properties are investigated by a simulation study.

description: We present a new modular traffic signs recognition system, successfully applied to both American and European speed limit signs. Our sign detection step is based only on shape-detection (rectangles or circles). This enables it to work on grayscale images, contrary to most European competitors, which eases robustness to illumination conditions (notably night operation). Speed sign candidates are classified (or rejected) by segmenting potential digits inside them (which is rather original and has several advantages), and then applying a neural digit recognition. The global detection rate is ~90% for both (standard) U.S. and E.U. speed signs, with a misclassification rate <1%, and no validated false alarm in >150 minutes of video. The system processes in real-time ~20 frames/s on a standard high-end laptop.
A performer's interpretation of Andrew Ford's Tales of the Supernatural
Creators: name: Joughin, PF
Publisher: name: University Of Tasmania
Year: 2023

description: Australian composer Andrew Ford (1957-) is well known within Australia as a Radio presenter for the ABC, and perhaps lesser known as a composer. He has a catalogue of over 160 works including a large number of commissions which span many different styles and orchestrations and cover a range of subjects including dramatic, topical, fanciful and historical. His compositions range from extremely atonal to tonal. They vary in difficulty, but remain accessible to the ear and have been performed by some of Australia's most prominent artists. This research explores one specific piece/ Tales of the Supernatural composed in 2002. This set of folk songs for voice and string quartet has been performed only a small number of times, each time with a female singer. Given Ford's propensity for clarity in intention, I have chosen to explore the possibility and implications of the piece being performed by male voice, and also evaluate his use of the texts that comprise the cycle and the way he sets them to music. The cycle is a collection of six folk tales, one of which is repeated to bring the cycle to a close. I have concentrated on each of the tales as they are set within the cycle, looking at their thematic content, devices and motives used and overall effect as a subset ofthe whole cycle. In studying the characteristics of Ford's work, I also outline my interpretation ofthis work and the outcomes for both myself as singer, and the quartet. Through this examination and evaluation, this research raises awareness of one of Andrew Ford's compositions and broadens the performance opportunities for the work by its inclusion in repertoire for male medium to low voice.

The observed inclusive cross section of neutral kaons points to an in-medium modification in the production. The momentum dependent ratio of cross sections of light and heavy target nuclei turns out to be a sensitive observable for the in-medium potential strength in transport codes. The experiments will continue studying the production of charged kaons with elementary probes including the search for deeply bound antikaon nuclear clusters in proton proton collisions.

description: The rules of soft-collinear effective theory can be used naively to write hard scattering cross-sections as convolutions of separate hard, jet, and soft functions. One condition required to guarantee the validity of such a factorization is the infrared safety of these functions in perturbation theory. Using e+e- angularity distributions as an example, we propose and illustrate an intuitive method to test this infrared safety at one loop. We look for regions of integration in the sum of Feynman diagrams contributing to the jet and soft functions where the integrals become infrared divergent. Our analysis is independent of an explicit infrared regulator, clarifies how to distinguish infrared and ultraviolet singularities in pure dimensional regularization, and demonstrates the necessity of taking zero-bins into account to obtain infrared-safe jet functions.

description: We propose a realistic Beta-Beam experiment with four source ions and two baselines for the best possible sensitivity to theta_{13}, CP violation and mass hierarchy. Neutrinos from 18Ne and 6He with Lorentz boost gamma=350 are detected in a 500 kton water Cerenkov detector at a distance L=650 km (first oscillation peak) from the source. Neutrinos from 8B and 8Li are detected in a 50 kton magnetized iron detector at a distance L=7000 km (magic baseline) from the source. Since the decay ring requires a tilt angle of 34.5 degrees to send the beam to the magic baseline, the far end of the ring has a maximum depth of d=2132 m for magnetic field strength of 8.3 T, if one demands that the fraction of ions that decay along the straight sections of the racetrack geometry decay ring (called livetime) is 0.3. We alleviate this problem by proposing to trade reduction of the livetime of the decay ring with the increase in the boost factor of the ions, such that the number of events at the detector remains almost the same. This allows to substantially reduce the maximum depth of the decay ring at the far end, without significantly compromising the sensitivity of the experiment to the oscillation parameters. We take 8B and 8Li with gamma=390 and 656 respectively, as these are the largest possible boost factors possible with the envisaged upgrades of the SPS at CERN. This allows us to reduce d of the decay ring by a factor of 1.7 for 8.3 T magnetic field. Increase of magnetic field to 15 T would further reduce d to 738 m only. We study the sensitivity reach of this two baseline two storage ring Beta-Beam experiment, and compare it with the corresponding reach of the other proposed facilities.

description: We study B_s --> mu+ mu- in the context of the R-parity violating minimal supergravity in the high tan beta regime. We find that the lowest value of the branching ratio can go well below the present LHCb sensitivity and hence B_s --> mu+ mu- can even be invisible to the LHC. We also find that the present upper bound on Br(B_s --> mu+ mu-) puts strong constraint on the minimal supergravity parameter space. The constraints become more severe if the upper bound is close to its standard model prediction.

description: Virtuoso cellist, pedagogue and composer, David Popper was an instrumental figure in the development of cello technique in the late nineteenth and early twentieth centuries. Popper's technical principles and innovations are laid down in his monumental work the Hohe Schule des Violoncello-Spiels. Certainly his greatest contribution, these forty immensely challenging and musically-rewarding etudes are now studied all over the world. A thorough understanding of the many techniques required in these etudes, as well as effective practice methods, are crucial for a cellist's development of technical skills. These techniques and practice methods have been somewhat overlooked in the available literature. Previous discussions focus on only one or two techniques for each etude, however these etudes require many more techniques than have been acknowledged. These techniques are common to all members of the violin family and can be applied to any repertoire requiring these techniques.
Evaluating the reproducibility of respondent-driven sampling: using repeated surveys among people who inject drugs in New Jersey

description: Due to stigma or legal issues, populations with higher HIV risk are often hard to reach, which impedes accurate population estimation of HIV burden. To better sample hard-to-reach populations for HIV surveillance, various sampling methods have been designed and/or used since HIV Epidemic following first reported AIDS cases in 1981. As a sampling method to reduce biases of chain-referral samples and to obtain statistically unbiased estimates of population parameters, respondent-driven sampling has been widely used for hard-to-reach populations in HIV surveillance. However, limited studies have assessed the empirical reproducibility of RDS. This dissertation has three specific aims: (1) to review the development of various sampling methods for hard-to-reach populations in HIV surveillance, and then to critically review the assessment of different sampling methods with a focus on RDS; (2) to assess the reliability of naïve RDS samples; (3) to evaluate the consistency of population parameter estimates based on four RDS estimators (RDS-I, RDS-II, Gile’s SS, and HCG). Five rounds (Range of sample size: 394-524) of the National HIV Behavioral Surveillance – People Who Inject Drugs Surveys in Newark, New Jersey were used. The study shows that relatively good reliability of RDS samples and consistency of RDS-II and Gile’s SS estimators were observed. Future studies should consider the superiority of RDS under a specific situation and conduct diagnostic procedures during the stage of data collection to assure implementation accuracy when RDS is used.
Collective bargaining under a compulsory conciliation system in the British Columbia coast forest industry 1947-1968

description: This thesis examines the behavior of bargaining parties under a statutory scheme of compulsory conciliation. The statutory scheme used in the study is the basic pattern of conciliation effective in British Columbia from 1947 to 1968. Its general function is explained in a summarization of published criticisms of the process. A particular bargaining relationship -- that of the coast forest industry negotiations -- is examined on a historical and institutional basis to discover specific characteristics which would influence behavior under a conciliation process. Using this predicted pattern of interaction, a model of party behavior is constructed for the parties involved in actual negotiations. This is tested against a summarized chronology of the actual bargaining that occurred from 1947 to 1968. The model reveals the important sections within a system of compulsory conciliation which influence the behavior of the parties during negotiations. It also emphasizes the importance of the apparent fairness of the recommendation stage of conciliation and its value to the union as a tactical "watershed" for continued bargaining. The development of the dynamic process of party interaction in the coast forest industry emphasizes the importance of union internal or intra-organizational difficulties. It suggests the existence of a limit to the effectiveness of any bargaining system which does not control the desires of the union rank and file. With the dynamic process in mind, the analysis examines some of the influences that changing the statutory process would have upon the behavior of the parties. On this basis the actual significance or effectiveness of some past changes is analyzed and new changes are proposed. Too, the basic limits inherent in the compulsory conciliation system as a control over party behavior are emphasized.

description: MgB2 monofilamentary nickel-sheated tapes and wires were fabricated by means of the ex-situ powder-in-tube method using either high-energy ball milled and low temperature synthesized powders. All sample were sintered at 920 C in Ar flow. The milling time and the revolution speed were tuned in order to maximize the critical current density in field (Jc): the maximum Jc value of 6 x 10e4 A/cm2 at 5 K and 4 T was obtained corresponding to the tape prepared with powders milled for 144h at 180rpm. Vorious synthesis temperature were also investigated (730-900 C) finding a best Jc value for the wire prepared with powders synthesized at 745 C. We speculate that this optimal temperature is due to the fluidifying effect of unreacted magnesium content before the sintering process which could better connect the grains.

description: (Note: this is a shortened version of the original "structured" A&A format abstract.) We performed a large optical spectroscopic and photometric survey of the Lynds~1630N and 1641 clouds. We provide a catalog of 132 confirmed young stars in L1630N and 267 such objects in L1641. We identify 28 transition disk systems, 20 of which were previously unknown, as well as 42 new transition disk candidates for which we have broad-band photometry but no optical spectroscopy. We estimate mass accretion rates M_acc from the equivalent widths of the H_alpha, H_beta, and HeI 5876Åemission lines, and find a dependence on stellar mass of M_acc propto Mstar^alpha, with alpha~3.1 in the subsolar mass range that we probe. An investigation of a large literature sample of mass accretion rate estimates yields a similar slope of alpha~2.8 in the subsolar regime, but a shallower slope of alpha~2.0 if the whole mass range of 0.04 M_sun-5 Msun is included. Among the transition disk objects, the fraction of stars that show significant accretion activity is relatively low compared to stars with still optically thick disks (26\pm11% vs. 57\pm6%, respectively). However, those transition disks that do show significant accretion have the same median accretion rate as normal optically thick disks of 3-4*10^{-9} M_sun/yr. We find that the ages of the transition disks and the WTTSs without disks are statistically indistinguishable, and both groups are significantly older than the CTTSs. These results argue against disk-binary interaction or gravitational instability as mechanisms causing a transition disk appearance. Our observations indicate that disk lifetimes in the clustered population are shorter than in the distributed population. We propose refined Halpha equivalent width criteria to distinguish WTTSs from CTTSs.

description: We report on a multi-frequency, multi-epoch campaign of Very Long Baseline Interferometry observations of the radio galaxy 1946+708 using the VLBA and a Global VLBI array. From these high-resolution observations we deduce the kinematic age of the radio source to be $\sim$4000 years, comparable with the ages of other Compact Symmetric Objects (CSOs). Ejections of pairs of jet components appears to take place on time scales of 10 years and these components in the jet travel outward at intrinsic velocities between 0.6 and 0.9 c. From the constraint that jet components cannot have intrinsic velocities faster than light, we derive H_0 > 57 km s^-1 Mpc^-1 from the fastest pair of components launched from the core. We provide strong evidence for the ejection of a new pair of components in ~1997. From the trajectories of the jet components we deduce that the jet is most likely to be helically confined, rather than purely ballistic in nature.
