description: Anisotropy of the cosmic microwave background radiation (CMB) originates from both tensor and scalar perturbations. To study the characteristics of each of these two kinds of perturbations, one has to determine the contribution of each to the anisotropy of CMB. For example, the ratio of the power spectra of tensor/scalar perturbations can be used to tighten bounds on the scalar spectral index. We investigate here the implications for the tensor/scalar ratio of the recent discovery (noted in astro-ph/0410139) that the introduction of a minimal length cutoff in the structure of spacetime does not leave boundary terms invariant. Such a cutoff introduces an ambiguity in the choice of action for tensor and scalar perturbations, which in turn can affect this ratio. We numerically solve for both tensor and scalar mode equations in a near-de-sitter background and explicitly find the cutoff dependence of the tensor/scalar ratio during inflation.

description: Increasing demands in the fields of high-precision force measurement and weighing technology require an ever-higher measurement resolution, a larger measurement range, a lower measurement uncertainty, and traceability to a natural constant. Load cells using the compensation principle have the potential to fulfill these requirements. To enhance the measurement resolution and decrease the measurement uncertainty, the residual stiffness of the compliant mechanism in use needs to be compensated. Due to a lack of solutions in the state of the art, a novel monolithic stiffness-compensated mechanism for measurements according to the compensation principle was developed. Simulations show a stiffness reduction to 0.2%of the initial value, a theoretical force resolution of 31 pN, and applicability for any orientation in the gravity field. Experimental investigations on a prototype confirmed the existing potential. However, further optimization of the mechanism is required to negate the effects of manufacturing deviations.

description: Unlike isolated beta-cells, which usually produce continuous spikes or fast and irregular bursts, electrically coupled beta-cells are apt to exhibit robust bursting action potentials. We consider the noise induced by thermal fluctuations as well as that by channel gating stochasticity and examine its effects on the action potential behavior of the beta-cell model. It is observed numerically that such noise in general helps single cells to produce a variety of electrical activities. In addition, we also probe coupling via gap junctions between neighboring cells,with heterogeneity induced by noise, to find that it enhances regular bursts.

description: The study has examined the farmers’ perception regarding deterioration of pasturelands, its impact on livestock farming and the factors affecting farmers’ willingness to contribute to a participatory pasture development programme. It is based on the primary data collected from sheep farmers of semi-arid and arid regions of Rajasthan in the year 2008. A large proportion of farmers have perceived deterioration of the pastureland which has resulted in the reductions of wool yield per animal (18%), body weight of sheep (20%) and age of disposal of lambs (45%). The major coping mechanisms adopted by the farmers have been identified are: reduction in total livestock holding (86%), reduction in sheep flock size (55%), grazing on alternative fodder sources (30%), increased frequency of migration (59%), increased duration of migration (41%), and disposal of male lambs at an early age (76%). The reduction of pastureland has resulted in cost escalation for sheep farming, particularly for the landless and small farmers. Double Bounded Dichotomous Choice (DBDC) method of Willingness to Pay (WTP) has been used to analyze the factors affecting the association of farmers with a participatory pasture development programme. The bivariate probit model estimated using this data has indicated that the expected cost and the concerns regarding inequitable distribution of benefits affect WTP negatively, whereas flock size affects it positively. The farmers in the arid region have been found more forthcoming towards a participatory management strategy. The study has highlighted the importance of awareness generation about the participatory management strategy and its incorporation as a component of livestock development programmes.

description: The topic of human-centric design of smart production and logistics processes is increasingly debated in both academic and industrial communities. However, there is still little existing research on the integration of this concept with companies’ daily operations. The research presented in this paper aims to expand this area of research by proposing a framework designed for the logistics sector that includes human factors among the criteria for choosing the best technology to adopt based on the company’s requirements. The framework, which is, therefore, a decision support tool for technology adoption, is subsequently validated through a multiple case study. The results of the validation highlight the framework’s potential as a tool to better understand the human factors involved in tasks and technologies to be adopted in order to avoid possible critical issues related to technological changes (e.g. acceptability, need for additional investment in training, identification of required skills).

description: Based on the current state of research, the aim of this paper is to develop a position sensor for actuators using passive magnetic shape memory alloys. The presented sensor concept converts the strain dependent permeability of the magnetic shape memory alloy into an inductance change by using a sensor coil arrangement. The change in inductance of the sensor coil is converted into a change in the resonant frequency of a parallel oscillating circuit. A microcontroller detects the resonant frequency of the circuit and converts it into a position sensor signal. To evaluate the functionality of the sensor, a test rig is developed that deforms the magnetic shape memory element under realistic application conditions. Experimental measurements in a climate chamber are used to evaluate the performance and characteristics of the sensor. The characteristic, temperature drift and hysteresis behavior are analyzed. It is proven that the presented sensor concept can be used to determine the position of passive magnetic shape memory alloy actuators.

description: We study the $A$ dependence of the $ϕ$ meson production cross section in proton nucleus reactios at energies just above threshold, which are accessible in an experimental facility like COSY. This $A$ dependence has two sources: the distortion of the incident proton and the absorption of the $ϕ$ in its way out of the nucleus. This second process reduces the cross section in about a factor two in heavy nuclei. Thus we show that the $A$ dependence of the cross section contains valuable information on the $ϕ$ width in the nuclear medium.

Exports of Livestock Products from India: Performance, Competitiveness and Determinants

Subjects: Agricultural and Food Policy

description: The paper has examined temporal changes in the composition of livestock exports, assessed the export competitiveness of different livestock products and analysed the factors affecting the growth of livestock export. The performance of livestock export has been found noteworthy. The liberalization policy initiated in 1991 seems to have improved the performance of livestock exports. The study has revealed that India is competitive in export of meat products, except poultry. The export of buffalo meat has been increasing consistently and the poor domestic demand has further fuelled its export. But, the export of mutton does not seem to have much prospects in the short-run, as even the domestic demand is not being met by domestic production. In milk and milk products, India has some advantage at the farm level, but is not competitive in export of milk and milk products under the prevailing world market situation. The domestic policy initiatives and increased production and productivity have been identified as the important factors in increasing the export of livestock products. The study has suggested that strengthening of export supply capacity domestically holds the key for enhancing export of livestock products rather than expanding world market.

description: Crossbreds hold the solution to the milk-deficit problem of North-Eastern states of India. The proportion of crossbred cattle in the region is 7.54 per cent (3.46 per cent of the country) as against 13.33 per cent for the country as a whole. However, the productivity of crossbred cattle has been found considerably low (4.8 L/day) in the region as against the all-India average of 6.4 L/day of milk yield. Yield gap analysis has been applied to find out the intra-regional milk yield gaps and the factors that could be addressed in the short-run to make-up the deficit. Based on the analysis, it has been identified that the major factors affecting the milk yield of crossbred animals in the N-E states are the technological and socio-economic constraints, which could be addressed by adopting improved management practices, better feeding practices, controlling of diseases and amelioration of the socio-economic conditions of the farmers through training, education and enhancing access to the funds. Addressal of these constraints will increase actual milk yield by about 66 per cent, sufficient enough to meet the deficit of milk requirement in the region. Category-wise yield gap analysis has shown that the highest increase in milk yield will be obtained on medium category households. The factors significantly affecting the milk yield at the household level are allocation of human-days per animal, expenditure on concentrate, economic status of the farmer and availability of the green fodder in the surroundings. While no major breakthrough is expected immediately, improvement in these factors would meet the milk deficit in the region.

description: As a model of thermally excited flux liquids connected by a weak link, we study the effect of a single line defect on vortex filaments oriented parallel to the surface of a thin planar superconductor. This problem can be mapped onto the physics of a Luttinger liquid of interacting bosons in 1 spatial dimension with a point impurity. When the applied magnetic field is tilted relative to the line defect, the corresponding quantum boson Hamiltonian is non-Hermitian. We analyze this problem using a combination of analytic and numerical (density matrix renormalization group) methods, uncovering a delicate interplay between enhancement of pinning due to Luttinger liquid effects and depinning due to the tilted magnetic field. Interactions allow a single columnar defect to be very effective in suppressing vortex tilt when the Luttinger liquid parameter g less than equal to 1.

description: This study explores the potential of audible range airborne sound emissions from Gas Metal Arc Welding (GMAW) to create an automated classification system using neural networks (NN) for weld seam quality inspection. Irregularities in GMAW process (oil presence, insufficient shielding gas) may lead to porosity imperfections in weld seams. Using Directed Energy Deposition-Arc additive manufacturing, aluminum (Al) and steel wall structures were produced with varying shielding gas flows or applying oil. Acoustic emissions (AE) generated during the welding process were captured using audible to ultrasonic range microphones. Mel spectrograms were computed from the AE data to serve as input to NN during training. The proposed model achieved notable accuracies in classifying both Al weld seams (83% binary, 68% multi-class) and steel welds (82% binary, 58% multi-class). These results demonstrate that employing audible range AE and NN in GMAW monitoring offers a viable method for low-latency monitoring and valuable insights into improving welding quality.

description: In 1958 Brigadier J.W. Kaye wrote an article for these Transactions about the woollen industry at Millbeck, north of Keswick. Using title deeds and the mill day books for 1830-1841, he identified the extensive nature of the mill complex, built from the late 1700s onwards, along with the products it made and where they were sent during its heyday. The authors were asked by the National Trust, which now owns part of the site, to identify remaining features of the mill complex and to undertake further historical research in order to provide a fuller picture of the site before, during and after the operation of the mills. With access to records not available to Kaye, the authors have been able to provide such a picture, particularly as regards the later years of the mills and the post-woollen mill years.

description: The increasing demand for last-mile delivery has created a challenge for urban consolidation centers (UCCs). Due to UCC’s limited delivery capacity, it has to purchase spare capacity from carriers. In the procurement, the UCC cannot observe the carriers’ efforts, resulting in low-quality logistics services. Thus, we propose a reverse auction mechanism considering logistics service quality (LSQ) for the UCC’s procurement of last-mile delivery capacity. First, we construct the benchmark of the mechanism by introducing the LSQ in last-mile delivery and presenting a reverse auction. Then, we develop an auction model with ideas of ensuring the UCC’s incentive and awarding business to the carriers who deliver high-quality services. The case study shows that the proposed mechanism is an efficient procurement tool for the UCC with a guarantee of LSQ, and the UCC will benefit from the proposed mechanism by significant total cost saving as well as effective use of resources.

description: In this research are proposed the consequences of high temperatures in Internal Combustion Motors (ICM) as correlation of its performance according to give information of the ICM fault detector, which also can be useful for preventive maintenance. It was possible to achieve the proposed target because of it was designed a smart sensor based in nanostructures prepared over Anodic Aluminum Oxide (AAO) samples, which proportionated short response time and high robustness in the measurement tasks of the smart sensor, as well as, the designed sensor has the possibility to work by energy self-sufficiency and sending the measurement data to external users by wireless. In fact, it is waited that this research could be a support for researchers of ICM enhancement, who could look for new techniques of environment conditions cares in compensation to keep the balance between the useful energy obtained from ICM and the environment conditions, where are developed economical activities such as public transport or mining in Peru.

description: We present a lattice formulation of a dynamic self-consistent field (DSCF) theory that is capable of resolving interfacial structure, dynamics and rheology in inhomogeneous, compressible melts and blends of unentangled homopolymer chains. The joint probability distribution of all the Kuhn segments in the fluid, interacting with adjacent segments and walls, is approximated by a product of one-body probabilities for free segments interacting solely with an external potential field that is determined self-consistently. The effect of flow on ideal chain conformations is modeled with FENE-P dumbbells, and related to stepping probabilities in a random walk. Free segment and stepping probabilities generate statistical weights for chain conformations in a self-consistent field, and determine local volume fractions of chain segments. Flux balance across unit lattice cells yields mean-field transport equations for the evolution of free segment probabilities and of momentum densities on the Kuhn length scale. Diffusive and viscous contributions to the fluxes arise from segmental hops modeled as a Markov process, with transition rates reflecting changes in segmental interaction, kinetic energy, and entropic contributions to the free energy under flow.

description: We consider the quantum mechanics of Einstein gravity linearised about flat spacetime. The two transverse-traceless components of the metric perturbation are the true physical degrees of freedom. They appear in the quantum theory as free quantum fields. Like the full Einstein action, the Euclidean action for linearised gravity is unbounded below. It is therefore not possible to use that action to represent the ground state wave function as a Euclidian functional integral over exp{[-(action) /\hbar]}. However, it is possible to represent the ground state as a Euclidian integral over the (deparametrised) action involving only the true physical degrees of freedom. Starting from this integral representation of the ground state and using the techniques of Faddeev and Popov we show how to construct a Euclidean functional integral for the ground state wave function. The integral explicitly exhibits the theory's gauge symmetry, locality, and O(4) invariance. The conformal factor appears naturally rotated into the complex plane. Other representations of the ground state are exhibited.

title: The Impact of Irradiation Particle Type and Energy on Radiation-induced Trap Properties in CCDs
Creators: name: Lindley-Decaire, Anton
Publisher: name: The Open University
Year: 2021

description: This thesis describes a study on the impact of irradiation particle type and particle energy on silicon based detectors. Radiation damage is a major limiting factor to achieving high accuracy scientific observations in space and can reduce a mission’s operational lifetime. Highly energetic particles can penetrate through satellites, reflect off the mirrors in the focal plane (e.g., Chandra) or interact with the body of the satellite to produce secondary particles that are energetic enough to fluoresce or damage the devices. The energetic particle can displace a silicon atom from its regular lattice position and the resulting vacancy (the lattice position absent of a silicon atom) can migrate through the device until it finds an energetically stable pairing. This degrades the performance of the detector and therefore quality of the science delivered. There is currently no ideal solution to fully mitigate radiation damage, instead any remaining damage must be corrected post-irradiation. This correction requires a complete understanding of the damage mechanisms and a real time measurement of the damage sites in the imaging area. Upcoming missions such as Euclid require a high level of post-imaging corrections to meet the ambitious scientific goals and will be utilising the “trap pumping” technique in-orbit to perform live characterisations on the active defects. The trap pumping technique is used extensively in this study to identify radiation induced defects in the silicon lattice by characterising defects introduced by energetic interactions at various energies and doses, including irradiation by protons, photons, neutrons and electrons. Different particle types and energies can cause ionisation damage, single atom displacement damage or clusters of atomic displacements. In this study several new and important results have been identified relating to n-channel defects. These defects are specific to particle type and energy. In particular the presence of a “fast tail” of emission time constants of the divacancy are found for proton and neutron irradiations and absent in gamma irradiations. Furthermore, a spread of emission times is found for all particle irradiations which indicates traps may occupy a distribution of energies/cross sections around an energy level rather than a single fixed emission time constant for each trap species. This work also shows that potential pockets can be falsely identified as traps through the trap pumping technique when insufficient datapoints are used. These results improve our fundamental understanding of trap dynamics in n-channel silicon and can help shape the strategy for damage mitigation and testing strategy for trap pumping in CCD based satellite missions.
Back to the future : the museum exhibit Vancouver in the fifties and the problem of historicity
Creators: name: Knights, Wayne Robert
Publisher: name: University of British Columbia
Year: 2009

description: Critics of the museum have repeatedly drawn attention to its paradoxical quality. On the one hand, the museum is an institution dedicated to the historical representation of the past. On the other, the construction of exhibitions and displays is almost entirely dependent on the act of separating historical objects from their actual, temporal existence and subsequently resurrecting them in totalized narratives of interpretation. Not only has the object lost its actual context and temporality in this process, but it is also enclosed in a reconstruction that is epistemologically problematic from the point of view of an accurate representation of that context. In an unexpected way, the museum takes on the metaphoric characteristics of the mausoleum. Consequently, the experience of historicity that the visitor might well take from museum is, in Maurice Merleau- Ponty's formulation, the historicity of death. Against this, curators can only hope to 'imaginatively' bring the past back to life, thereby running the risk of seriously misrepresenting both the past and our experience of historicity. I argue that this paradox cannot be transcended by the museum. Moreover, we can infer that historiography faces the same sort of dilemma. However, this is exacerbated by the tendency to focus on the problematic of history as representation over the notion of history as event and process when defining either historical consciousness or historicity. Through a careful reading of both Gadamer's work on historical consciousness and what I understand as a fundamental corrective to it offered by Reinhart Koselleck, I argue that any attempt to understand the experience of historicity must grasp the significance of the dimension of futurity. Whereas the emphasis on history as representation inevitably falls on the past and its relationship to the historian's present, the relation of both past and present to the future constitutes historical temporality. Koselleck shows how the tension between what he calls the space of experience and horizons of expectation constitutes historicity historically. In order to make this argument, I analyze a new exhibit entitled "Vancouver in the Fifties" at the Vancouver Museum. The virtue of this exhibit is that it manages to portray the tension between that particular present past and the corresponding horizon of expectation that shapes its future present. Potentially; the visitor leaves the exhibit with a sense of the play of temporality implied by the existence of an open future in the past. This stands as a kind of case study aimed at underlining the importance of the historicity of the future for understanding historical temporality.
Dataplane Based Fast Failover in SDN-Enabled Wide Area Measurement System of Smart Grid
Creators: Tong Duan, Venkata Dinavahi
Publisher: name: University of Alberta Library
Year: 2022

In the wide area measurement system (WAMS) of

smart grid, the real-time monitoring and protection applications

have stringent requirements for the end-to-end transmission

delays between PMUs and PDC, and fast failover is required to

ensure the communication performance after link failures. In this

work, the software-defined network (SDN) technology is utilized

to enable datapath failover upon a link failure with a global view

of the communication network. Then, a novel dataplane based

fast failover (DFF) mechanism is proposed to directly re-route

the data packet in dataplane without interacting with the SDN

controller. Based on the mathematical analysis over the WAMS

topology features, the proposed DFF optimizes two procedures of

failover: backup path construction, and backup path installation.

Using the proposed backup path construction algorithms, the

3-approximate and (1+2")-approximate (0 < " < 1) backup

paths can be constructed, theoretically guaranteeing the data

transmission delays both during and after failover. Using the

proposed LinkID-based FF group table installation method, the

conflict of forwarding rules between original and backup paths

can be eliminated, while the storage cost is also optimized. The

simulation results on six IEEE benchmark test power systems

show that the proposed DFF mechanism could achieve lower

data transmission delays during and after failover compared to

the existing control plane based and dataplane based failover

mechanisms.

Prehistoric and Later Remains on Land off Meadowlands Avenue, Barrow-in-Furness

description: A programme of archaeological work carried out in advance of a proposed housing estate on land off Meadowlands Avenue, Barrow-in-Furness revealed several features of interest in a geophysical survey. These were subsequently examined by targeted evaluation trenching and two areas of 'strip and record'. A group of small pits was revealed in one area, one of which was radiocarbon dated to the Neolithic. The form of the pit group, assuming they are all of the same date, is suggestive of a short-lived structure, and seems similar to another excavated nearby. A collection of linear features in another area related mainly to land drainage; one culvert was partially built of dressed red sandstone reused from nearby Furness Abbey. The reuse of stone taken from Furness Abbey after the Dissolution adds to examples in the locality.
Two examples of how to use observations of terrestrial planets orbiting in temperate orbits around low mass stars to test key concepts of planetary habitability

description: Terrestrial planets in temperate orbits around very low mass stars are likely to have evolved in a very different way than solar system planets, and in particular Earth. However, because these are the first planets that are and will be accessible for in-depth atmosphere, clouds and surface characterizations with existing and forthcoming telescopes, we need to develop the best possible observational strategies to maximize the scientific return from these characterizations. Here I discuss and expand on the recent works of Bean et al. (2017) and Turbet et al. (2019) to show that terrestrial planets orbiting in temperate orbits around very low mass stars are potentially an excellent sample of planets to test how universal the processes thought to control the habitability of solar system planets and in particular Earth are. Precise measurements of density or atmospheric CO2 concentration for planets located both inside and outside the Habitable Zone could be used to statistically test habitability concepts such as the silicate-weathering feedback, CO2 condensation, or runaway greenhouse, which have been identified as key processes controlling the present and past habitability of Venus, Mars and Earth.

description: This paper presents the results of archaeological investigations undertaken by Wardell Armstrong on land at Carleton Heights, Penrith. The work revealed evidence of prehistoric activity, representing two distinct periods: the early Bronze Age and middle/late Bronze Age. There is evidence of both on-site occupation and of likely local land-use and exploitation.

description: We continue our study of a new boundedness condition for affine permutations, motivated by the fruitful concept of periodic boundary conditions in statistical physics. We focus on bounded affine permutations of size $N$ that avoid the monotone decreasing pattern of fixed size $m$. We prove that the number of such permutations is asymptotically equal to $(m-1)^{2N} N^{(m-2)/2}$ times an explicit constant as $N\to\infty$. For instance, the number of bounded affine permutations of size $N$ that avoid $321$ is asymptotically equal to $4^N (N/4π)^{1/2}$. We also prove a permuton-like result for the scaling limit of random permutations from this class, showing that the plot of a typical bounded affine permutation avoiding $m\cdots1$ looks like $m-1$ random lines of slope $1$ whose $y$ intercepts sum to $0$.

description: We present Sloan g and i imaging from the GMOS instrument on the Gemini North telescope for the globular cluster (GC) system around the Virgo galaxy NGC 4649 (M60). Our three pointings, taken in good seeing conditions, cover an area of about 90 sq. arcmins. We detect 2,151 unresolved sources. Applying colour and magnitude selection criteria to this source list gives 995 candidate GCs that is greater than 90% complete to a magnitude of i = 23.6, with little contamination from background galaxies. We find fewer than half a dozen potential Ultra Compact Dwarf galaxies around NGC 4649. Foreground extinction from the nearby spiral NGC 4647 is limited to be A_V < 0.1. We confirm the bimodality in the GC colour distribution found by earlier work using HST/WFPC2 imaging. As is commonly seen in other galaxies, the red GCs are concentrated towards the centre of the galaxy, having a steeper number density profile than the blue GC subpopulation. The varying ratio of red-to-blue GCs with radius can largely explain the overall GC system colour gradient. The underlying galaxy starlight has a similar density profile slope and colour to the red GCs. This suggests a direct connection between the galaxy field stars and the red GC subpopulation. We estimate a total GC population of 3700 +/- 900, with the uncertainty dominated by the extrapolation to larger radii than observed. This total number corresponds to a specific frequency S_N = 4.1 +/- 1.0. Future work will present properties derived from GMOS spectra of the NGC 4649 GCs.
