Light scalar mesons: comments on their behavior in the 1/Nc expansion near Nc=3 versus the Nc --> infinity limit

description: We briefly review how light meson resonances are described within one and two-loop Unitarized Chiral Perturbation Theory amplitudes and how, close to Nc=3, light vectors follow the Nc behavior of $q\bar q$ mesons whereas light scalars do not. This supports the hypothesis that the lightest scalar is not predominantly a $q\bar q$ meson, although a subdominant $q\bar q$ component is suggested around 1 GeV at somewhat larger Nc. In contrast, when Nc is very far from 3, like in the Nc --> infinity limit, we explain again in detail why unitarization is not, a priori, reliable nor robust and why this limit should not be used to drag any conclusions about the dominant nature of physical light scalar mesons.

description: This paper is concerned with an extension of the well known Kaluza-Klein mechanism. As the standard ansatz for Kaluza-Klein reduction implies the existence of a gauge potential associated with the KK field strength, it follows immediately that this field strength satisfies its Bianchi identity. Hence, the standard KK formalism breaks down in the presence of a violated Bianchi identity. This occurs for example in the context of D6 sources. We will investigate and partially solve this problem in the context of the type IIA/M-theory duality. Our discussion is motivated by the construction of gauge/string duals with backreacting flavor branes using D6-branes, which appear in M-theory as KK-monopoles. We are able to derive source-modified equations of motion for the eleven-dimensional theory, and are subsequently able to obtain the source-modified type IIA equations by direct dimensional reduction.

title: The Influence of Age on the Cation Exchange Capacity of Plant Roots
Creators: name: Haniuk, Einard S.
Publisher: name: Utah State University
Year: 1959

description: A yellowing which develops in some plants growing on naturally calcareous soils is called lime-induced chlorosis. The problem is complex, as indicated by Brown and Holmes (1956) and Porter and Thorne (1955). Species and varieties of plants differ in their iron requirements, susceptibility to lime- induced chlorosis, and inter acting soil f actors which affect iron supply (Thorne et al 1950). Chlorosis of plants does not appear, therefore, to stem from a common causative factor. At least a part of this difference has been found to be associated with the plant roots. Thus, through the use of resistant root stock Wann (1941) was able to produce non-chlorotic grapes. These grapes grown under similar conditions without the resistant root stock would have been high1y chlorotic. Certain citrus root stocks have also been used on calcareous soils because they give citrus trees resistance to chlorosis.

description: The year 2008 has witnessed remarkable steps in developing high energy neutrino telescopes. IceCube at the South Pole has been deployed with 40 of its planned 80 strings and reached half a cubic kilometer instrumented volume, in the Mediterranean Sea the "first-stage" neutrino telescope ANTARES has been completed and takes data with 12 strings. The next years will be key years for opening the neutrino window to the high energy universe. IceCube is presently entering a region with realistic discovery potential. Early discoveries (or non-discoveries) with IceCube will strongly influence the design and the estimated discovery chances of the Northern equivalent KM3NeT. Following theoretical estimates, cubic kilometer telescopes may just scratch the regions of discovery. Therefore detectors presently planned should reach sensitivities substantially beyond those of IceCube.

Publisher: name: Utah State University
Year: 1969

description: The intent of this study was to preserve the historical heritage of a small Canadian community. The thought that in the strength of a community lies the strength of a nation.
The following things were taken into consideration in giving a complete picture of Raymond: (l) The early history which entailed the parts that the Indians, the whoop-up saga, the trader, the trapper, and the Northwest Mounted Police played in the development of Western Canada and Alberta. (2) The desire of the Government to open the western prairies for settlement which brought the Mormon people who were seeking new homes . With the Mormons came the controversy of polygamy, a problem that had to be resolved. (3) The influence and contribution of the Jesse Knight family in the development of Raymond and the surrounding area. (4) The development of Raymond as a prosperous and progressive community involving the sugar beet industry, farming, irrigation, ranching, and the eventual growth of businesses, educational facilities, and religious activities.
The research and sources used for the desired information carne from original diaries , micro- films, newspapers , interviews, correspondence, and books.
The findings and feelings of the residents of Raymond express their pride in their community and their desire to have their stories preserved.
Formation of bound states of electrons in spherically symmetric oscillations of plasma

description: We study spherically symmetric oscillations of electrons in plasma in the frame of classical electrodynamics. Firstly, we analyze the electromagnetic potentials for the system of radially oscillating charged particles. Secondly, we consider both free and forced spherically symmetric oscillations of electrons. Finally, we discuss the interaction between radially oscillating electrons through the exchange of ion acoustic waves. It is obtained that the effective potential of this interaction can be attractive and can transcend the Debye-Huckel potential. We suggest that oscillating electrons can form bound states at the initial stages of the spherical plasma structure evolution. The possible applications of the obtained results for the theory of natural plasmoids are examined.

People, perceptions and policies: public sector workforce alignment
Creators: name: Gonda, KS
Publisher: name: University Of Tasmania
Year: 2023

description: Australian workplaces are experiencing substantial challenges because of population ageing. In addition, the labour market is highly competitive, so organisations need to offer competitive employment terms and conditions to attract, engage and retain talented employees. Paralleling this is evidence of the need for workplace flexibility, with organisations requiring greater structural flexibility to increase efficiencies and productivity, and individuals wanting flexible working arrangements for work-life balance. Literature indicates that different generations hold different expectations and aspirations about work. Strategic Human Resource Management [SHRM] theory prescribes that organisations should align their workforces to meet organisational goals, with workforce policies determined by the senior executive. Literature addressing current workforce challenges is deficient in addressing public sector workforce management, particularly the different environment in which it exists and operates. This literature fails to recognise the importance and value of how managers' and employees' perceptions about their employment can contribute to determining appropriate workforce policies to achieve sustainable workforces. The current research examined attraction, engagement and retention in public sector Agencies, using in-depth interviews with public sector employees and managers to record their perceptions about their employment prior to commencement and currently, and the factors influencing their ongoing service. A survey of public sector Agencies assessed the types and level of alignment of Human Resources [HR] practices and policies against the themes of attraction, engagement and retention. The findings show that employees' perceptions about their employment are more cohesive than the literature indicates. The need for job security, challenging work and community contribution were values shared by participants, but their interpretations varied. Employee results were compared with managers' perceptions and the Agency survey findings to identify what attraction, engagement and retention factors are held to be valuable and whether there was an alignment with organisational policies and practices. The findings highlight the need for a considered organisational approach that incorporates employees' and managers' perceptions about their employment. The results contribute to understanding how public services can manage and sustain their workforces by developing appropriate HR practices and policies. This study was unique in that it drew evidence from employees' and managers' perceptions about attraction, engagement and retention, and contrasted this with organisational policies and practices. The importance of informal flexible workplace arrangements was a key finding. The research adds to the emerging body of knowledge regarding workforce management, particularly how knowledge of employees' perceptions can contribute to building effective policies that meet individual and organisational needs.
title: The Thermodynamics and Some Practical Aspects of Zinc Adsorption on Calcite, Dolomite, and Calcian-Magnesite Minerals
Creators: name: Jurinak, Jerome J.
Publisher: name: Utah State University
Year: 1956

description: Zinc is one of the essential elements required for the normal growth plants. The total amount of zinc commonly occurring in soils is usually many times greater than that necessary to supply the needs of actively growing plants. The ability of the soil to "fix" zinc in form unavailable for plant use, however, has made the zinc deficiency disease an important plant nutrition problem in the major fruit and nut growing regions of the West. Fixation mechanisms which have been postulated as contributing to zinc deficiency include organic complexes, precipitation of insoluble inorganic salts, and strong zinc-clay interactions. It may be possible that in certain soils naturally occurring soil minerals, other than the clay minerals, may also exert an influence on the capacity of the soil to retain zinc.
The accumulation of lime minerals is a distinguishing profile characteristic of soils in arid and semi-arid region and semi-arid regions. These minerals include: calcite (CaCO3), dolomite (CaMg(CO3)2), and magnesite (MgCO3). Despite the widespread occurrence of these minerals in the soil system, relatively few data exist which specifically isolate the interaction between cations in solution and the solid phase of the above-named lime minerals.

description: The Lie superalgebra sl(r+1|s+1) admits several inequivalent choices of simple root systems. We have carried out analytic Bethe ansatz for any simple root systems of sl(r+1|s+1). We present transfer matrix eigenvalue formulae in dressed vacuum form, which are expressed as the Young supertableaux with some semistandard-like conditions. These formulae have determinant expressions, which can be viewed as quantum analogue of Jacobi-Trudi and Giambelli formulae for sl(r+1|s+1). We also propose a class of transfer matrix functional relations, which is specialization of Hirota bilinear difference equation. Using the particle-hole transformation, relations among the Bethe ansatz equations for various kinds of simple root systems are discussed.

description: We present a design and a top-down fabrication method for realizing diamond nanowires in both bulk single crystal and polycrystalline diamond. Numerical modeling was used to study coupling between a Nitrogen Vacancy (NV) color center and optical modes of a nanowire, and to find an optimal range of nanowire diameters that allows for large collection efficiency of emitted photons. Inductively coupled plasma (ICP) reactive ion etching (RIE) with oxygen is used to fabricate the nanowires. Drop-casted nanoparticles (including $\mathrm{Au}$, $\mathrm{SiO_{2}}$ and $\mathrm{Al_2O_3}$) as well as electron beam lithography defined spin-on glass and evaporated $\mathrm{Au}$ have been used as an etch mask. We found $\mathrm{Al_2O_3}$ nanoparticles to be the most etch resistant. At the same time FOx e-beam resist (spin-on glass) proved to be a suitable etch mask for fabrication of ordered arrays of diamond nanowires. We were able to obtain nanowires with near vertical sidewalls in both polycrystalline and single crystal diamond. The heights and diameters of the polycrystalline nanowires presented in this paper are $\unit[\approx1]{μm}$ and $\unit[120-340]{nm}$, respectively, having a $\unit[200]{nm/min}$ etch rate. In the case of single crystal diamond (types Ib and IIa) nanowires the height and diameter for different diamonds and masks shown in this paper were $\unit[1-2.4]{μm}$ and $\unit[120-490]{nm}$ with etch rates between $\unit[190-240]{nm/min}$.

description: If binaries are common among massive stars, it will have important consequences for the derivation of fundamental properties like the cluster age, IMF and dynamical mass. Making use of the multiplexing facilities of Gemini Multi Object Spectrograph (GMOS) we were able to investigate the presence of binary stars within the ionising cluster of 30 Doradus. From a seven epochs observing campaign at Gemini South we detect a binary candidate rate of about 50%, which is consistent with an intrinsic 100% binary rate among massive stars. We find that single epoch determinations of the velocity dispersion give values around 30 km/s . After correcting the global velocity dispersion for the binary orbital motions, the true cluster velocity dispersion is 8.3 km/s. This value implies a virial mass of about 4.5E5 Msun or 8 percent of the mass calculated using the single epoch value. The binary corrected virial mass estimate is consistent with photometric mass determinations thus suggesting that NGC 2070 is a firm candidate for a future globular cluster.

title: The Peltier Effect and its Use for Measuring Relative Activity of Soil Water
Creators: name: Korven, Hans C.
Publisher: name: Utah State University
Year: 1958

description: Soil moisture measurement embraces two basic concepts, namely, water content and relative activity. The measurement of moisture content, either on a weight or volume basis, yields the amount or quantity of water in the soil. The measurement of relative activity or the energy required to remove unit of water is related to the availability of the soil moisture to the plant. The measurement of soil bulk density, irrigation efficiency, and the amount of water to apply in an irrigation are a few examples that require the use of the moisture content concept. Whereas the first concept determines the amount of water to apply; the second cencept, since it is related to the tenacity with which water is held in the soil or the availability of soil water to the plant, determines the correct time to irrigate. Other examples of phenomena that relate closely to the relative activity concept are found in the study of seepage loss from canals and in the design of drainage systems to lower the water table (water movement).

The mechanism is most efficient in the fully connected network.

Aspects of the life history of Lycodopsis pacifica (Collett) 1879
Creators: name: Levings, Colin D.
Publisher: name: University of British Columbia
Year: 2011

description: Aspects of the life history of Lycodopsis pacifica (Collett) 1879 were studied during the period September 1965 to November 1966. Two areas in the Strait of Georgia, British Columbia, were investigated. Trawls were used as sampling devices. Sexually mature individuals were collected during the period September to January. Lycodopsis pacifica has a remarkably small complement of mature eggs (average complement 30.4), The mature eggs are large, with an average diameter of 5.0 mm. Sexual dimorphism is present. Males start to grow faster than females at approximately 170 mm in length. The older males are' larger than females. There is some evidence that parental care is involved in the reproductive behaviour of the species. Age was estimated by counting the annular rings on otoliths. Both males and females ranged up to five years of age. The age-length relationship for both sexes is presented. The length-weight relationship of the species is described. The food spectrum of Lycodopsis pacifica was determined. At outer Burrard Inlet, the species feeds primarily on infaunal invertebrates of the Phyla Mollusca and Annelida, and the Sub-phylum Crustacea, The place of L. pacifica in the bottom community is considered. The anatomy of structures associated with feeding are described. Visual and "chemical" senses are probably important in food-getting behaviour. The feeding adaptations and food of the species is discussed in relation to sediment type. L. pacifica is probably not specialized to remove infaunal food items from one type of sediment. It was assumed that Lycodopsis pacifica would aggregate where high concentrations of infaunal organisms suitable as food would be found. At outer Burrard Inlet, high numbers were caught on several sediment types, ranging from silt-sand to silt. At the Cape Lazo area, catches of L, pacifica were highest on a silt sediment. The species is likely capable of foraging on a range of sediment types. Some factors affecting the infauna are discussed, and the usefullness of simple mechanical analysis of sediments in benthic ecology is questioned.
title: Influence of Fertilizer Treatment on the Response of Sugar Beet Yield to Moisture

description: Many factors that influence the growth and quality of sugar beets behave in one way under one set of conditions and in quite another under other conditions. Consequently, these factors should be considered together under a dynamic situation to find their interrelations and their influence on sugar beet yield.
This study is a statistical analysis of the interaction of fertilizer and soil moisture potential with the yield of sugar beets grown in a crop rotation under different regimes of irrigation conducted over a period of seven years.
The data are available for the years 1949 through 1956, from an intensive field experiment conducted under Western Regional Research Project W-29, entitled Soil-Water-Plant Relations under Irrigation.
There is need of a complete statistical analysis of third order interaction for the whole cultural rotation. This third order interaction has been examined for the sugar beet crop grown in the seven years of the general cultural rotation, which includes peas, first year alfalfa, second year alfalfa, potatoes, and sugar beets.

Delivering a curriculum by Team Based Learning (TBL) requires a structured approach over a two week cycle. Students are presented with an authentic problem at the beginning of the first week and the group uses a variety of learning opportunities (from lectures, workshops and self-directed activities) to answer the problem. At the beginning of the second week, individual students compare their performance with other members of the group and any difficulties in understanding the key learning points are clarified and this is followed by a further variety of learning opportunities. At the end of each week, there is a group reflection on both the learning and group processes.
title: Nature of Non-Biological Decomposition of Nitrite in Acid Media
Creators: name: Mahendrappa, Mukkatira Kariappa
Publisher: name: Utah State University
Year: 1966

description: Curiosity is the cause of investigations, and the thirst for knowledge originates from it. Many times at the end of investigations, the number of questions raised are greater than those for which answers are sought. Therefore, all the information gathered through scientific investigations may not be of value for immediate application in practical life. Nevertheless, no research can be considered less important than the other because the integration of several scientific findings considered less less important at the time of investigation may reveal something of very high significance. Similarly, the study of various transformation reactions that the added fertilizers undergo may not be of value to the one whose main objective is to increase production, though it is of great value for the efficient use of fertilizers. Information on the reactions of each intermediate compound produced during the transformations of ammoniacal fertilizers may be useful in reducing or preventing the loss of N that could arise through some of the reactions. Such knowledge will be useful for the economical use of fertilizers.
Nitrite is an intermediate compound produced in nitrification, denitrification, and nitrite reduction processes. Chemistry of nitrite in alkaline solutions is well understood, while its fate in acid soils and solutions has eluded the attention of most workers. This is probably due to the fact that under acid conditions nitrite does not appear in large quantities contrary to its behavior in the alkaline region. However, the existence of nitrite in smaller concentrations under acid conditions suggests the possibility that it may be rapidly transformed to other forms of N and may lead to the loss of added N. The rates of such reactions and losses may be higher in acid than in alkaline soils.
In acid solutions nitrite also exists as un-ionized nitrous acid; the concentration of the latter form increases at higher acidities. In the following pages these two terms, nitrite and nitrous acid, will be used interchangeably. In acid soils, nitrous acid undergoes several changes such as its fixation by various soil components, chemical conversion to other N compounds, and loss of N either as N2 or in the form of oxides of nitrogen. Most of these reactions may probably result in reduced nitrogen availability to the crops.
In this investigation some of the factors influencing nitrite transformations, such as non-biological nitrification and loss of N in different forms, were studied. Validity of some of the proposed nitrite decomposition pathways were verified, and conditions favoring individual reactions were studied in various soil and resin systems.

description: To obtain the profiles of dry bulb and wet bulb temperature, specific humidity, q, and air density, ρ, to a height of 200 meters above the ground, a precise lightweight thermocouple psychrometer was designed. To lift the thermocouple psychrometer and the attached wires in obtaining the ρq profiles, a rigid polyethylene balloon augmented with 5.5-feet outdoor or 100-g meteorological balloons were used. Using the height dependent eddy exchange coefficient and a one-dimensional time-dependent profile model, the nighttime variations of ρq as a function of height were predicted and compared with observed values. It was found that the general shape of the eddy exchange coefficient, K(Z), was approximately the same as found in recent literature.
title: Investigations of Field Performance and Physiological Effects of Metsulfuron and Metsulfuron Combinations on Field Bindweed (Convolvulus arvensis L.)
Creators: name: Mashhadi, Hamid Rahimian
Publisher: name: Utah State University
Year: 1987

description: Field bindweed (Convolvulus arvensis L.) is a noxious perennial weed of many fallow and cropland fields all over the world. Present control methods are not satisfactory for field bindweed. Metsulfuron, 2[[[[(4-methoxy-6-methyl-1,3,5-triazine-2-yl) amino] carbonyl] amino] sulfonyl] benzoic acid, is a new herbicide that has been shown to have activity on bindweed especially when tank mixed with other herbicides. This study was conducted to investigate the field performance and some physiological effects of metsulfuron on field bindweed.
Neither metsulfuron alone nor metsulfuron combinations gave persistent control of field bindweed. Metsulfuron usually increased the activity of other bindweed herbicides. Herbicide application to field bindweed in the full bloom growth stage did not control the weed as well as the same treatments in the prebloom growth stages and treating regrowth the fall after tilling bindweed in full blossom. Application of metsulfuron at full bloom decreased seed weight, seed size seed viability and seedling vigor of field bindweed but did not alter seed set.
Metsulfuron at 23 g/ha and above caused unacceptable injury to barley (Hordeum vulgaris L.) and oats (Avena sativa L.). Higher rates of metsulfuron resulted in greater phytotoxicity.
Metsulfuron stopped photosynthesis of field bindweed within two weeks regardless of herbicide dosage used. Field bindweed seedlings were observed growing in the field under light intensities of 28 to 62 μmoles m-2 s-1 which was below the light compensation point obtained for greenhouse grown bindweed plants (about 65 μmoles m-2 s-1).
Higher quantities of 14C labelled metsulfuron per mg plant dry weight were recovered in the above treated leaf sections than in any other parts of bindweed plants. Metsulfuron applied as a foliage spray two days prior to administering 14C metsulfuron significantly increased absorption to the radiolabelled herbicide in field bindweed plants.
title: Cation Exchange and Transport in Soil Columns Undergoing Miscible Displacement
Creators: name: Lai, Sung-ho
Publisher: name: Utah State University
Year: 1970

description: A mathematical model was developed to predict the exchange of one cation by another in a soil column undergoing one dimensional cation solution displacement under steady state flow conditions. The model allowed prediction of both the solution and exchanger phase concentration of the cation in question.
The model consists of a material balance equation which is a parabolic type partial differential equation. The assumption was made that equilibrium was reached instantaneously between the cations in the solution phase and the exchanger phase. This assumption reduced the material balance equation to a form that allowed numerical solution providing the data concerning the cation exchange isotherm and the initial and boundary conditions are available.
FORTRAN programs were written for the numerical computation of the problem involved. The computation was done on a digital computer.
The model was verified by comparing the theoretically computed cation concentration profile with data from actual soil column experiments. The cation exchange of Mg→Ca was tested on Yolo fine sandy loam, Nibley clay loam and Haford Sandy loam columns. The exchange of Na→Ca was also tested on Yolo fine sandy loam. Satisfactory agreement between the column experiment values and the theoretically computed values was obtained.

description: We use neutron scattering, to study magnetic excitations in crystals near the ideal superconducting composition of FeTe$_{0.5}$Se$_{0.5}$. Two types of excitations are found, a resonance at (0.5, 0.5, 0) and incommensurate fluctuations on either side of this position. We show that the two sets of magnetic excitations behave differently with doping, with the resonance being fixed in position while the incommensurate excitations move as the doping is changed. These unusual results show that a common behavior of the low energy magnetic excitations is not necessary for pairing in these materials.

title: The Influence of Temperature on the Impedance to Water Flow Through Plants
Creators: name: Jensen, Royal Duane
Publisher: name: Utah State University
Year: 1961

description: This era has been termed the atomic or space age. The greatest concern of most people seems to be centered around survival from the destruction and suffering that might be caused by atomic and nuclear weapons. However, along with this, the world is confronted with perhaps a greater disaster--a potential calamity seldom realized by most people, yet a problem which grows more serious in the world each year--a tragedy which would probably be worse than destruction from nuclear weapons. This encroaching catastrophe is starvation.
Even today the majority of the people in the world do not have enough food. Each year the acreage of fertile, productive land decreases because of expanding populations, misuse and the extinsive cropping of many years. As time proceeds, agriculturalists will be required to produce more food with less land resources. Undoubtedly, agricultural scientists will be confronted with greater challenges. Many of these problems will require extensive "basic" research. Now, while food in America is plentiful, seems the proper time to perform this basic research and prepare for the challenges that are going to come.
Since much of the world land area is semi-arid, the limiting factor in food production is water. There is an urgent need to use irrigation water more efficiently. In order to do this, more basic information concerning water-growth relations in the soil-plant-atmosphere system is needed. Water movement in the plant element of the system is perhaps the least understood. This classical problem has been extensively studied, yet many important problems still exist. The knowledge in many areas is a scarce and contradictory. Basic research and investigation must be continued.
this investigation was a plant-water relations study with the purpose of obtaining basic knowledge about the processes and phenomena involved in water transport through plants. The location and magnitude of the resistance to water flow in plants and the effect of temperature on water movement in plant tissue were the two aspects of water flow investigated. Other more minor subjects of study included: (a) water transport and the effect of mechanical suction, and (b) the correlation of water movement in plants with various measurements of plant response.

description: This study investigates factors that promote integration of port oriented supply chains. More specifically, the study examines the factors that foster integration of intermodal supply chain at the sea-land interface and their relative importance. This was investigated by first seeking expert's inputs through an informal survey, and secondly using those inputs from experts in combination with relevant literature review on the topic to formulate a formal internet survey that was used to collect data in order to answer the research question. Based on the investigation, the study had revealed factors that promote supply chain integration at the sea-land interface in their order of relative importance. The study found that communication across supply chain was the first relative important factor followed by supply chain performance, third was organizational trust, interface integration was fourth, and supply chain security was voted fifth from the list of ten supply chain factors that were investigated. The study also found that, with respect to interface dimensions, organizational aspect was voted the first relative important factor, followed by physical aspect and business operating environment was third in promoting supply chain integration at the sea-land interface of a port oriented intermodal supply chain.

description: A new planet has been recently discovered around Proxima Centauri. With an orbital separation of ~1.44 au and a minimum mass of about $7\,{M}_{\oplus }$, Proxima c is a prime direct imaging target for atmospheric characterization. The latter can only be performed with a good understanding of the space environment of the planet, as multiple processes can have profound effects on the atmospheric structure and evolution. Here, we take one step in this direction by generating physically realistic numerical simulations of Proxima's stellar wind, coupled to a magnetosphere and ionosphere model around Proxima c. We evaluate their expected variation due to the magnetic cycle of the host star, as well as for plausible inclination angles for the exoplanet orbit. Our results indicate stellar wind dynamic pressures comparable to present-day Earth, with a slight increase (by a factor of 2) during high-activity periods of the star. A relatively weak interplanetary magnetic field at the distance of Proxima c leads to negligible stellar wind Joule heating of the upper atmosphere (about 10% of the solar wind contribution on Earth) for an Earth-like planetary magnetic field (0.3 G). Finally, we provide an assessment of the likely extreme conditions experienced by the exoplanet candidate Proxima d, tentatively located at 0.029 au with a minimum mass of 0.29 M⊕.
title: Reducing the Noise Impact of Unmanned Aerial Vehicles by Flight Control System Augmentation
Creators: name: Galles, Matthew B.
Publisher: name: Old Dominion University Libraries

description: The aim of this thesis is to explore methods to reduce the noise impact of unmanned aerial vehicles operating within acoustically sensitive environments by flight control system augmentation. Two methods are investigated and include: (i) reduction of sound generated by vehicle speed control while flying along a nominal path and (ii) reduction of acoustic exposure by vehicle path control while flying at a nominal speed. Both methods require incorporation of an acoustic model into the flight control system as an additional control objective and an acoustic metric to characterize primary noise sources dependent on vehicle state. An acoustic model was developed based on Gutin’s work to estimate propeller noise, both to estimate source noise and observer noise using two separate acoustic metrics. These methods can potentially mitigate the noise impact of unmanned aerial systems operating near residential communities.

The baseline flight control system of a representative aircraft was augmented with a control law to reduce propeller noise using feedback control of the commanded flight speed until an acoustic target was met, based on the propeller noise model. This control approach focuses on modifying flight speed only, with no perturbation to the trajectory. Multiple flight simulations were performed and the results showed that integrating an acoustic metric into the flight control system of an unmanned aerial system is possible and useful. A second method to mitigate the effects of noise on an observer was also pursued to optimize a trajectory in order to avoid an acoustically sensitive region during the path planning process. After the propeller noise model was incorporated into the vehicle system, simulations showed that it is possible to reduce the noise impact on an observer through an optimization of the trajectory with no perturbation to the flight speed.

description: One of the greatest challenges and opportunities facing the South Pacific is rapid urbanisation, and Solomon Islands faces some of the most pressing urban growth stresses in the region. Its urban population is increasing at around 4.4 percent, almost twice the rate of national population growth — a tempo that will double urban dwellers in less than 17 years (Keen & Barbara 2015). As part of a broader study of urbanisation in Honiara, this In-Brief examines online urban news articles from July 2014 to June 2016 reported in the main newspaper, Solomon Star. The study investigates the capacity of press media to accurately and independently communicate urban issues.

description: The third generation of gravitational wave observatories, aiming to provide 100 times better sensitivity than currently operating interferometers, is expected to establish the evolving field of gravitational wave astronomy. A key element for achieving the ambitious sensitivity goal is the exploration of new interferometer geometries, topologies and configurations. In this article we review the current status of the ongoing design work for third-generation gravitational wave observatories. The main focus is set on the evaluation of the detector geometry and detector topology. In addition we discuss some promising detector configurations and potential noise reduction schemes.

description: Base sequences BS(n+1,n) are quadruples of {1,-1}-sequences (A;B;C;D), with A and B of length n+1 and C and D of length n, such that the sum of their nonperiodic autocorrelation functions is a delta-function. The base sequence conjecture, asserting that BS(n+1,n) exist for all n, is stronger than the famous Hadamard matrix conjecture. We introduce a new definition of equivalence for base sequences BS(n+1,n) and construct a canonical form. By using this canonical form, we have enumerated the equivalence classes of BS(n+1,n) for n <= 30. Due to excessive size of the equivalence classes, the tables in the paper cover only the cases n <= 13.
