description: Die Vision ‘Erdgeschoss Neu Denken’ versucht mit einem kreativen Ansatz, Fragen im Bereich der Urbanität zu beantworten und gleichzeitig innovative Lösungen für bauliche Maßnahmen in Bestandssituationen zu schaffen. Anhand einer Analyse der beiden Themen ‘Wiener Tourismus’ und ‘Wiener Erdgeschosszone’ werden Ziele festgelegt, die für die Verwirklichung der Vision relevant sind: Eine Alternative an Online-Plattformen, wie Airbnb, für günstige Übernachtungen und ein neues Konzept für sinnvolle Umnutzung von erdgeschossigen Leerständen zu entwickeln. Themen wie ‘Kommunikation im Grätzl’ und ‘Entzug von Wohnungen durch touristische Vermietungen’ werden behandelt, um zukunftsorientierte Lösungen im städtischen Bereich zu finden. Die Vision sollte überall dort umgesetzt werden, wo es möglich ist, jedes Grätzl einbinden zu können. Um ein einheitliches Konzept zu schaffen, wird eine CorporateIdentity entwickelt, die gleichzeitig als Designstatement für das gesamte Projekt steht.

Based on an analysis of two topics ‘The Viennese Tourism’ and ‘The Viennese Groundfloor’, relevant goals are set for the realization of the vision: An alternative to online platforms such as Airbnb for affordable overnight stays, and a new concept for sensible conversion of vacant ground floorspaces. Topics like ‘communication’ and ‘withdrawal of apartments by tourist rentals’ are dealt in order to find future-oriented solutions in urban context. The vision should be implemented where verpossible to include every neighbourhood in order to create a uniform concept. Acorporate identity is developed, which also serves as a design statement for the entire project.

description: Although gravitational-wave signals from exceptional low-mass compact binary coalescences, like GW170817, may carry matter signatures that differentiate the source from a binary black hole system, only one out of every eight events detected by the current Advanced LIGO and Virgo observatories are likely to have signal-to-noise ratios large enough to measure matter effects, even if they are present. Nonetheless, the systems' component masses will generally be constrained precisely. Constructing an explicit mixture model for the total rate density of merging compact objects, we develop a hierarchical Bayesian analysis to classify gravitational-wave sources according to the posterior odds that their component masses are drawn from different subpopulations. Accounting for current uncertainty in the maximum neutron star mass, and adopting different reasonable models for the total rate density, we examine two recent events from the LIGO-Virgo Collaboration's third observing run, GW190425 and GW190814. For population models with no overlap between the neutron star and black hole mass distributions, we typically find that there is a $\gtrsim 70\%$ chance that GW190425 was a binary neutron star merger rather than a neutron-star--black-hole merger. On the other hand, we find that there is a $\lesssim 6\%$ chance that GW190814 involved a slowly spinning neutron star, regardless of our assumed population model.

description: Recently certain non-supersymmetric solutions of type IIb supergravity were constructed [hep-th/0504181], which are everywhere smooth, have no horizons and are thought to describe certain non-BPS microstates of the D1-D5 system. We demonstrate that these solutions are all classically unstable. The instability is a generic feature of horizonless geometries with an ergoregion. We consider the endpoint of this instability and argue that the solutions decay to supersymmetric configurations. We also comment on the implications of the ergoregion instability for Mathur's `fuzzball' proposal.

description: Reduction in coffee consumption has required from coffee organizations the development of marketing techniques so as to creating value to their product as well as reaching consumer’s satisfaction. This work aimed at identifying questions on coffee consumers’ desires, perceptions, preferences and habits in Lavras, MG. The conclusive/descriptive research model was used, by means of which primary data were gathered through personal/individual surveys using structured questionnaires. It was verified that consumers are not loyal to coffee brands and that the determining factors in theirs choices are taste, price and yelding. Packaging must feature information on production site, manufacture and expiration dates, type, product classification, as well as information on the warrant stamp, yelding and brand.

description: The present work aimed at the analysis of the influences of the sucession in board of directors in the continuity of the strategies of an agricultural cooperative. It is a quantitative research work, particularly, a study case in which the data were collected and analyzed on a documents and personal interview basis. The results showed that in the political articulations involved in the electoral campaign , both slates made use of formal and informal tactics in addition to a true arsenal of political marketing, the slate of opposition faring victory . The close political dispute between the two slates left traumatic reflexes on all involved in the process ( members of the winning and losing slates , employees and cooperates) Political and ideological divergences among the members of the present board of directors and the previous managers caused a discontinuity in some strategies formulated and implemented in the previous one which sought to imprint both efficiency and competitiveness to the cooperative. It was found in such cases that the influence of the change in the administration was negative. Political and electoral interests over the cooperative’s real economical and entrepreneurial ones may be presented as the main motives to account for the discontinuity of the strategies of the cooperative investigated

description: We demonstrate how to efficiently expand cross sections for color-singlet production at hadron colliders around the kinematic limit of all final state radiation being collinear to one of the incoming hadrons. This expansion is systematically improvable and applicable to a large class of physical observables. We demonstrate the viability of this technique by obtaining the first two terms in the collinear expansion of the rapidity distribution of the gluon fusion Higgs boson production cross section at next-to-next-to leading order (NNLO) in QCD perturbation theory. Furthermore, we illustrate how this technique is used to extract universal building blocks of scattering cross section like the N-jettiness and transverse momentum beam function at NNLO.

description: A generic half-BPS surface defect of ${\mathcal N}=4$ supersymmetric U$(N)$ Yang-Mills theory is described by a partition of $N = n_1 + \ldots + n_M$ and a set of $4M$ continuous parameters. We show that such a defect can be realized by $n_I$ stacks of fractional D3-branes in Type II B string theory on a $\mathbb{Z}_M$ orbifold background in which the brane world-volume is partially extended along the orbifold directions. In this set up we show that the $4M$ continuous parameters correspond to constant background values of certain twisted closed string scalars of the orbifold. These results extend and generalize what we have presented for the simple defects in a previous paper.

Capacity and interference analysis of multicell CDMA systems using 3-dimensional smart antennas
Creators: name: Cheung, Titus Tin Hing
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, we derive analytical expressions for the interference and estimate the capacity of a CDMA based wireless system for indoor mobiles in 6 groups of high riser buildings occupying 6 building blocks of a typical high density downtown city environment. The analysis compares the performances of a single element panel antenna, a 1-dimensional linear array, and a 3-dimensional vertical planar array. We further consider an appropriate 3-dimensional urban model representative for such an environment, and based upon this model, a more accurate 3-dimensional user distribution is introduced. Our work has shown that, for such an environment, the traditional assumption of uniform user distribution is not valid. It is found that by arranging smart antenna elements in specific 2- and 3-dimensional geometries, reduction of sidelobes and significant improvements in the directivity can be achieved with the same number of elements traditionally used in a 1-dimensional linear array. For a more accurate analysis, short dipoles and panel antenna elements are used instead of isotropic point sources. Surface plots for the interference and capacity from the 6 building groups for different vertical and azimuth angles are produced. The capacity with the use of a 3-dimensional smart antenna and the improvement over a linear array are then compared, taken into account of different building materials' and dimensional effects. These performance evaluation results have shown that, as compared to the 1-dimentional linear array employing the same number of antennas, significant capacity improvements are achievable.
Spectral Analysis of Guanine and Cytosine Fluctuations of Mouse Genomic DNA

description: We study global fluctuations of the guanine and cytosine base content (GC%) in mouse genomic DNA using spectral analyses. Power spectra S(f) of GC% fluctuations in all nineteen autosomal and two sex chromosomes are observed to have the universal functional form S(f) \sim 1/f^alpha (alpha \approx 1) over several orders of magnitude in the frequency range 10^-7< f < 10^-5 cycle/base, corresponding to long-ranging GC% correlations at distances between 100 kb and 10 Mb. S(f) for higher frequencies (f > 10^-5 cycle/base) shows a flattened power-law function with alpha < 1 across all twenty-one chromosomes. The substitution of about 38% interspersed repeats does not affect the functional form of S(f), indicating that these are not predominantly responsible for the long-ranged multi-scale GC% fluctuations in mammalian genomes. Several biological implications of the large-scale GC% fluctuation are discussed, including neutral evolutionary history by DNA duplication, chromosomal bands, spatial distribution of transcription units (genes), replication timing, and recombination hot spots.

Deflating Quantum Mysteries via the Relational Blockworld

Year: 2005

description: We present a spacetime setting for non-relativistic quantum mechanics that deflates "quantum mysteries" and relates non-relativistic quantum mechanics to special relativity. This is achieved by assuming spacetime symmetries are fundamental in a blockworld setting, i.e., by interpreting spacetime relations as fundamental to relata. To justify this Relational Blockworld (RBW), we adopt a result due to G. Kaiser whereby the relativity of simultaneity, stemming from the Poincare algebra of special relativity, is responsible for the canonical commutation relations of non-relativistic quantum mechanics. And, we incorporate a result due to A. Bohr, B. Mottelson and O. Ulfbeck whereby the density matrix for a given experimental situation is obtained from its spacetime symmetry group. We provide an example to illustrate the explanatory nature of RBW and conclude by explaining how RBW deflates "quantum mysteries."

description: In this comment, we discuss the mathematical formalism used in Boumali et al. (2020) which describes the superstatistical thermal properties of a one-dimensional Dirac oscillator. In particular, we point out the importance of maintaining the Legendre structure unaltered to ensure an accurate description of the thermodynamic observables when a Tsallis-like statistical description is assumed. Also, we remark that all the negative poles have to take into account to calculate the Gibbs--Boltzmann partition function. Our findings show that the divergences obtained by the authors in the Helmholtz free energy, which are propagated to the other thermal properties, are a consequence of an incomplete partition function. Moreover, we prove that the restrictions over the $q$-parameter are no needed if an appropriate partition function describes the system.

description: We present Swift observations of the black hole X-ray transient, GRO J1655-40, during the recent outburst. With its multiwavelength capabilities and flexible scheduling, Swift is extremely well-suited for monitoring the spectral evolution of such an event. GRO J1655-40 was observed on 20 occasions and data were obtained by all instruments for the majority of epochs. X-ray spectroscopy revealed spectral shapes consistent with the ``canonical'' low/hard, high/soft and very high states at various epochs. The soft X-ray source (0.3-10 keV) rose from quiescence and entered the low/hard state, when an iron emission line was detected. The soft X-ray source then softened and decayed, before beginning a slow rebrightening and then spending $\sim 3$ weeks in the very high state. The hard X-rays (14-150 keV) behaved similarly but their peaks preceded those of the soft X-rays by up to a few days; in addition, the average hard X-ray flux remained approximately constant during the slow soft X-ray rebrightening, increasing suddenly as the source entered the very high state. These observations indicate (and confirm previous suggestions) that the low/hard state is key to improving our understanding of the outburst trigger and mechanism. The optical/ultraviolet lightcurve behaved very differently from that of the X-rays; this might suggest that the soft X-ray lightcurve is actually a composite of the two known spectral components, one gradually increasing with the optical/ultraviolet emission (accretion disc) and the other following the behaviour of the hard X-rays (jet and/or corona).

description: This work aimed at studying the contributions from the alternative rural educational practices in the process of construction of local development. In this context the study sought to understanding the manifestations of local development expressed in Comunidade do Giral-ES (Giral Community) and its relationship with the incorporation of knowledge by means of rural education. So, the variables related with the pedagogical practices which adopt the Alternance Pedagogy, its role in the building of the local development, its practice in the rural multicultural revalorization and its performance in the transforming performance of the subject as an agent of his own history. For the obtainance of information qualitative research techniques were used, for we see it as the most adequate in identifying the dimensions of local development and its relativization with rural education. It was verified that the educative practices acting in the community, for adopting an alternative pedagogic model expressed by the Alternance Pedagogy, provide the families with the opportunity of contraposition to the needs they face. In this context of changes which rural daily life is undergoing education becomes a factor of fundamental dimensions in the proceeding and consolidating of changes in the relationship with that new emerging reality, which involves family agriculture. One may conclude that a transforming rural education collaborates with the generation of capacity in the student so he will interact and transform his reality.

The results are then used to calibrate the temperature in several ground breaking experiments on $^6$Li and $^{40}$K.

description: Tourism in rural space is a tourism modality which has lately been the focus of investitors and students. However there has been little spread of studies focusing such modality, featuring the characteristics of te industry to which it belongs, showing up-to-date discussions and world trends. So, this study, concerned as it is with it, has gathered information on such points and shows that, worldwidely, tourism in rural space is an alternative modality that arose in counter-position to mass tourism, has been seen as a solution to poorer regions and, because of this, has been the aim of many investitors and students. The industry to which it belongs features characteristics like the complementarity of the segments that make it up and due to this it demands a different management style. By the problems raised, one believes that the essential question concerning tourism in rural space in the world is the lack of knowledge, both on behalf of the agents in dealing with the characteristics of the rural environment and the rural producers’ behalf in dealing with the characteristics of the tourism industry. The cluster, due to its characteristics, is the most adequate form to the characteristics of the tourism industry and especifically to tourism in rural space, which demands integration, coordination and cooperation. Once organized that way, tourism in rural space may come to smoothen problems said to be of regional under-development and de-valorization of small and medium rural enterprises that exist worldwide.

description: An economic evaluation of two Australian Centre for International Agricultural Research (ACIAR) projects in the area of postharvest technology for tropical fruits was undertaken. This evaluation considered a 30 year time period from the first year of investment and assumed a discount rate of 5 per cent. The estimate of the net present value of the research and development investment was $93 million expressed in 1996/97 terms. The benefit–cost ratio was 38:1 and the internal rate of return estimated at 64 per cent. If benefits realised by 1996/97 were considered, the net present value was $30 million, the benefit–cost ratio was 13:1, and the internal rate of return was 63 per cent. Benefits accrued to both Thailand and Australia, with the proportion of benefits attributed 52 per cent to Thailand and 48 per cent to Australia. The commodities to which benefits mostly related were mangoes in the case of Australia, and longans and durians in the case of Thailand. One of the technologies developed in Thailand for longans is now starting to be used in Australia in the developing longan industry.

description: We use first principles methods to study static and dynamical mechanical properties of the ferroelectric polymer Poly(vinylidene fluoride) (PVDF) and its copolymer with trifluoro ethylene (TrFE). We use density functional theory [within the generalized gradient approximation (DFT-GGA)] to calculate structures and energetics for various crystalline phases for PVDF and P(VDF-TrFE). We find that the lowest energy phase for PVDF is a non-polar crystal with a combination of trans (T) and gauche (G) bonds; in the case of the copolymer the role of the extra (bulkier) F atoms is to stabilize T bonds. This leads to the higher crystallinity and piezoelectricity observed experimentally. Using the MSXX first principles-based force field (FF) with molecular dynamics (MD), we find that the energy barrier necessary to nucleate a kink (gauche pairs separated by trans bonds) in an all-T crystal is much lower (14.9 kcal/mol) in P(VDF-TrFE) copolymer than in PVDF (24.8 kcal/mol). This correlates with the observation that the polar phase of the copolymer exhibits a solid-solid a transition to a non-polar phase under heating while PVDF directly melts. We also studied the mobility of an interface between a polar and non-polar phases under uniaxial stress; we find a lower threshold stress and a higher mobility in the copolymer as compared with PVDF. Finally, considering plastic deformation under applied shear, we find that the chains for P(VDF-TrFE) have a very low resistance to sliding, particularly along the chain direction. The atomistic characterization of these "unit mechanisms" provides essential input to mesoscopic or macroscopic models of electro-active polymers.

description: The specific heat $C$ of the single-layer cuprate superconductor HgBa$_2$CuO$_{4 + δ}$ was measured in an underdoped crystal with $T_{\rm c} = 72$ K at temperatures down to $2$ K in magnetic fields up to $35$ T, a field large enough to suppress superconductivity at that doping ($p \simeq 0.09$). In the normal state at $H = 35$ T, a residual linear term of magnitude $γ= 12 \pm 2$ mJ/K$^2$mol is observed in $C/T$ as $T \to 0$, a direct measure of the electronic density of states. This high value of $γ$ has two major implications. First, it is significantly larger than the value measured in overdoped cuprates outside the pseudogap phase ($p >p^\star$), such as La$_{2-x}$Sr$_x$CuO$_4$ and Tl$_2$Ba$_2$CuO$_{6 + δ}$ at $p \simeq 0.3$, where $γ\simeq 7$ mJ/K$^2$mol. Given that the pseudogap causes a loss of density of states, and assuming that HgBa$_2$CuO$_{4 + δ}$ has the same $γ$ value as other cuprates at $p \simeq 0.3$, this implies that $γ$ in HgBa$_2$CuO$_{4 + δ}$ must peak between $p \simeq 0.09$ and $p \simeq 0.3$, namely at (or near) the critical doping $p^\star$ where the pseudogap phase is expected to end ($p^\star\simeq 0.2$). Secondly, the high $γ$ value implies that the Fermi surface must consist of more than the single electron-like pocket detected by quantum oscillations in HgBa$_2$CuO$_{4 + δ}$ at $p \simeq 0.09$, whose effective mass $m^\star= 2.7\times m_0$ yields only $γ= 4.0$ mJ/K$^2$mol. This missing mass imposes a revision of the current scenario for how pseudogap and charge order respectively transform and reconstruct the Fermi surface of cuprates.

description: Larvae of the butterfly Erionota thrax, the banana skipper, destroy the leaves of bananas by eating them and forming massive protective rolls of leaf tissue. They were first observed in north-western Papua New Guinea in 1983 and over the next 6 years spread throughout the mainland at the rate of up to 500 km/year. E. thrax has also spread across the ocean to the east, to invade New Britain, Duke of York and New Ireland islands, and possibly Bougainville. As the banana skipper spread, it destroyed an average of some 60% of banana leaves, leading to both a serious delay in fruit maturation and reduced weight of banana bunches. Previous successful biological control of E. thrax when it invaded Mauritius, Hawaii, Guam and Saipan encouraged Papua New Guinea to launch an approach to ACIAR for funds. This was successful and a project was undertaken from 1988 to 1990. After careful tests to ensure that it was safe to do so, the larval parasite Cotesia erionotae was introduced and established, leading to a reduction in the estimated average leaf damage from about 60% to 5%. Using the estimated production value of bananas in Papua New Guinea to the year 2020, the losses due to banana skipper each year were calculated. Using a discount rate of 5%, the net present value of lost production amounts to approximately A$301.8 million. The value of damage prevented by biological control is estimated at $201.6 million. The reduction of banana skipper abundance by 90% in southern Papua New Guinea has correspondingly reduced the chance of adults invading not only Australian islands in the Torres Strait but also the Australian mainland. The successful biological control program in Papua New Guinea has therefore provided significant benefits to banana production in Australia. Assuming similar levels of damage in Australia as in Papua New Guinea, we estimate these benefits to be $223 million to the year 2020. The present value of total benefits from the ACIAR project equals $424.7 million ($201.6 million to Papua New Guinea and $223.1 million to Australia). This compares with the present value of the cost of the ACIAR project of $0.70 million, giving a benefit–cost ratio of 607 and an internal rate of return of 190%.

A new two-phase scatternet formation algorithm for bluetooth wireless personal area networks
Creators: name: Zhang, Chu
Publisher: name: University of British Columbia

description: A Bluetooth multi-hop personal area network can be formed by interconnecting one or more piconets into a scatternet. A Bluetooth scatternet is an ad hoc network in which the devices move randomly and organize themselves. The scatternet is attractive because it can extend the Bluetooth radio range and improve the network capacity. The current Bluetooth specification [1] only defines the scatternet but does not address how the scatternet is formed. To reduce the high load on the master nodes and bridge nodes, a twophase scatternet formation (TPSF) [8] algorithm has been proposed in which a control scatternet is created for the control traffic in the first phase and an on-demand scatternet is created for the data traffic in the second phase. In TPSF, route information for the ondemand scatternet on each node is discovered only when the node initially accesses the network. The original TPSF does not consider the support of mobility. In this thesis, we propose a new scheme which is called TPSF+ for the on-demand scatternet formation in the second phase of TPSF. In TPSF+, route information is discovered when a communication session is required between the two nodes. Consequently, the on-demand scatternet can be formed with much higher success ratio when the slaves randomly move around the master after accessing the network. We also propose to use PM_ADDR (Parked Member Address) instead of BD_ADDR (Bluetooth Device Address) during route discovery in order to reduce the time of the route discovery process. Furthermore, to reduce the hop distance of the on-demand scatternet, we limit the number of hops in each piconet in the control scatternet. Based on the simulation results, we show that our scheme can improve network performance greatly in terms of aggregate throughput and end-to-end delay even with the consideration of packet collisions. With the slaves randomly moving around the master, TPSF+ achieves much better performance in terms of a higher successful path connection ratio.

description: The sources of ultra-high energy (UHE) cosmic rays, which can have energies up to 10^20 eV, remain a mystery. UHE neutrinos may provide important clues to understanding the nature of cosmic-ray sources. ARIANNA aims to detect UHE neutrinos via radio (Askaryan) emission from particle showers when a neutrino interacts with ice, which is an efficient method for neutrinos with energies between 10^16 eV and 10^20 eV. The ARIANNA radio detectors are located in Antarctic ice just beneath the surface. Neutrino observation requires that radio pulses propagate to the antennas at the surface with minimum distortion by the ice and firn medium. Using the residual hole from the South Pole Ice Core Project, radio pulses were emitted from a transmitter located up to 1.7 km below the snow surface. By measuring these signals with an ARIANNA surface station, the angular and polarization reconstruction abilities are quantified, which are required to measure the direction of the neutrino. After deconvolving the raw signals for the detector response and attenuation from propagation through the ice, the signal pulses show no significant distortion and agree with a reference measurement of the emitter made in an anechoic chamber. Furthermore, the signal pulses reveal no significant birefringence for our tested geometry of mostly vertical ice propagation. The origin of the transmitted radio pulse was measured with an angular resolution of 0.37 degrees indicating that the neutrino direction can be determined with good precision if the polarization of the radio-pulse can be well determined. In the present study we obtained a resolution of the polarization vector of 2.7 degrees. Neither measurement show a significant offset relative to expectation.

description: The signing of the Economic Partnership Agreements (EPAs) between the European Union (EU) and the African Caribbean Pacific (ACP) nations dominated the multilateral trade agenda in late 2007 and early 2008. While the Caribbean nations signed the full EPAs, some of the African countries only singed interim agreements with the EU and a number of West African countries chose not to sign any EPA. Using the case of Botswana’s export markets, especially in agriculture, it is argued that the interim Southern African Development Community (SADC) EPA, which was signed by Botswana and her neighbours, with the exception of South Africa, may have been economically sensible in protecting Botswana’s rural poor, at least in the short run. By tracing trade flows from the border to specifically poor sectors of the country, the importance of the beef exports sector to the poor and rural communities was found. The potential effects on the most significant exports of tariff bands associated with preferential agreements with the EU were found to be most beneficial in comparison to the Most Favoured Nation (MFN) and the South Africa-EU Trade Development and Cooperation Agreement (TDCA) tariff bands. But it is also argued that the EPA will most likely have far reaching long run costs on regional economic development and institutional integration, within the SADC and Southern African Customs Union (SACU).

description: We study the stationary and nonstationary measurement of a classical force driving a mechanical oscillator coupled to an electromagnetic cavity under two-tone driving. For this purpose, we develop a theoretical framework based on the signal-to-noise ratio to quantify the sensitivity of linear spectral measurements. Then, we consider stationary force sensing and study the necessary conditions to minimise the added force noise. We find that imprecision noise and back-action noise can be arbitrarily suppressed by manipulating the amplitudes of the input coherent fields, however, the force noise power spectral density cannot be reduced below the level of thermal fluctuations. Therefore, we consider a nonstationary protocol that involves non-thermal dissipative state preparation followed by a finite time measurement, which allows one to perform measurements with a signal-to-noise much greater than the maximum possible in a stationary measurement scenario. We analyse two different measurement schemes in the nonstationary transient regime, a back-action evading measurement, which implies modifying the drive asymmetry configuration upon arrival of the force, and a nonstationary measurement that leaves the drive asymmetry configuration unchanged. Conditions for optimal force noise sensitivity are determined, and the corresponding force noise power spectral densities are calculated.
