PHOTOGRAMMETRIC SOFTWARE FOR THE LH SYSTEMS ADS 40 AIRBORNE DIGITAL SENSOR

Airborne linear array sensors present new challenges for photogrammetric software. The push-broom nature of these sensor systems has the potential for very high quality images, but these are heavily influenced by the dynamics of the aircraft during acquisition. Fortunately, highly precise position and attitude measurements have become possible, using today's inertial measuring units (IMUs). This allows image restoration to the sub-pixel level. The sensor discussed in detail here is a "three-line camera" with additional multispectral lines. The three lines are one looking forward, one in the nadir position and one looking backward with respect to the flight path. Extensive software processes are necessary to produce traditional photogrammetric products from a push-broom airborne sensor. The first steps of the ground processing flow are off-loading imagery and supporting data from the mass memory system of the sensor, post-processing of GPS/IMU data and image rectification into stereo-viewable and matchable form. After this processing, the images can be used similarly to classical aerial photography. This includes semi-automated triangulation with and without ground control, DTM production from multiple stereo views, vector extraction in mono and stereo, and orthophoto and mosaic production. The paper analyses the differences to classical photogrammetric processing for all processing steps and closes with a discussion of the advantages and disadvantages of this new type of photogrammetric imagery.
Canadian Journal of Environmental Education

Environmental education has a long and complex relationship with activism. Scholars of environmental education have explored this current of our discipline both explicitly and implicitly from a variety of perspectives. While some have proposed that environmental education is, by its very nature, political and activist-oriented (Stevenson, 1987/ 2007), others have critically pondered the role of environmental educators as activists (Jickling, 1991; 2003). Others still have advocated for the explicit rooting of environmental education in critical theory and pedagogy (Kahn, 2010). Additionally, or as an alternative, they have engaged in scholarship that questions and/or resists neoliberalism (Hursh, Henderson, and Greenwood, 2015), anthropocentrism (Lloro-Bidart, 2017) and anthropomorphism (Timmerman and Ostertag, 2011), colonialism (Tuck, Mckenzie and McCoy, 2014), heteropatriarchy (Martusewicz, 2013; Russell, Sarick, and Kennelly, 2002), and other manifestations of social and ecological oppression. In this scholarly context, activism remains an important, yet controversial, mainstay of environmental education theory, research, and practice. As such, we sought submissions for this special issue from diverse perspectives that specifically investigate the relationship between environmental education and activism.
SCIENTIFIC RESEARCH AND EDUCATION IN THE AIR FORCE – AFASES2017 295 DYNAMICS OF RECOIL SIMULATION DEVICE POWERED BY CARBON DIOXIDE

The paper is focused on the dynamics of the recoil simulation device powered by the carbon dioxide (CO2). The objective is to formulate a mathematical model simulating the cylinder pressurization, and the displacement of the recoil simulation device moving part. The CO2 is considered as the real gas. The speed of sound in a two-phase saturation is taken into account for the determination of the critical gas flow rate from the CO2 pressure tank into the cylinder. The problem is solved using the MATLAB environment and results of the theoretical solution are verified experimentally.
Dynamic Crack Analysis in Isotropic/Orthotropic Media via Extended Isogeometric Analysis

The extended isogeometric analysis (X-IGA) is the combination of the extended finite element method (X-FEM) and the isogeometric analysis (IGA), so the X-IGA possesses the advantages of both methods. In this paper, the X-IGA is extended to investigate the dynamic stress intensity factors of cracked isotropic/orthotropic media under impact loading. For this purpose, a corresponding dynamic X-IGA model is developed, the Newmark time integration scheme is used to achieve a dynamic response, and the dynamic stress intensity factors are evaluated through the contour interaction integral technique. Numerical simulations show that the X-IGA results agree with other available reference solutions, and accurate results can be obtained by using the X-IGA with a relatively coarse mesh.
Large Scale Physical Modeling Sound Synthesis

Stefan Bilbao, Brian Hamilton,Alberto Torin and Craig WebbAcoustics Group, University of Edinburghsbilbao@staffmail.ed.ac.ukPaul Graham, Alan Gray,Kostas Kavoussanakis and James PerryEPCC, University of EdinburghABSTRACTSound synthesis based on physical models of musical in-struments is, ultimately, an exercise in numerical simula-tion. As such, for complex systems of the type seen in mu-sical acoustics, simulation can be a computationally costlyundertaking, particularly if simplifying hypotheses, suchas those of traveling wave or mode decompositions are notemployed. In this paper, large scale time stepping meth-ods, such as the ﬁnite difference time domain and ﬁnitevolume time domain methods are explored for a variety ofsystems of interest in musical acoustics, includingbrass in-struments, percussion instruments based on thin plate andshell vibration, and also their embeddings in 3D acousticspaces. Attention is paid here to implementation issues,particularly on parallel hardware, which is well-suited totime stepping methods operating over regular grids. Soundexamples are presented.1. INTRODUCTIONPhysical modeling sound synthesis has been approachedina variety of ways; perhaps the best known methods are thelumped mass spring network methodology, developed byCadoz and associates [1], modal synthesis, developed atIRCAM [2] and digital waveguide methods developed bySmith at CCRMA [3], and subsequently greatly extended[4, 5, 6]. A direct comparison of these methods is dif-ﬁc ult (but possible [7])—all possess distinct advantages:lumped network methods allow an extreme degree of con-trol over the system, to the level of individual masses andsprings; modal methods offer the possibility of exact so-lutions when modal data is available in closed form, oreasily computed, and waveguides are extremely efﬁcientwhen the system under consideration behaves (nearly) asthe 1D wave equation, which is roughly true for a varietyof systems of interest in musical acoustics.Direct numerical simulation techniques, essentially timestepping methods such as the ﬁnite difference time domainmethod (FDTD) [8], or ﬁnite volume time domain method[9], though mainly used in other mainstream domains canalso be applied to the problem of sound synthesis; indeed,theywereproposedas longagoas 1969byRuiz [10], in the
The Effect of Heat Transfer Between Nearby Layers on the Volume of the Steam Zones

The work of Mandl and Volek is extended analytically to include the effect on the volume of the steam zone in one layer owing to heat transfer from a second layer undergoing steam injection. The contribution of the heat transfer delays the onset of heat convection across the advancing condensation front (the critical time) and significantly increases the volume of the steam zone even where 30 or more feet separate the layers. The increase in the heat content of the steam zone (or volume) increases with increasing ratio of the sensible to latent heat of the injected steam, and is larger than the increase in the total heat content. The interpretation for this behavior is that heat transfer delays the rate of condensation of the steam vapor, this being more important at poor steam qualities. Results of the simple approach presented here have been confirmed qualitatively through numerical simulation.
Optimum Performance of UHF RFID Tags in Dielectric Environment

Ultra High Frequency Radio Frequency Identification (UHF RFID) technology has gained prominence in recent years. It is being deployed extensively in supply chain and asset tracking by retailers to better control their inventory. The main drawback of UHF RFID tag antenna is that it is sensitive to the environment in which it operates. The performance of the tag degrades when placed on conductive or dielectric objects. While RFID tags near metal have been extensively evaluated in the literature, tags on and in dielectric media have received less scrutiny and rigorous evaluation. In this thesis, we develop a rigorous theoretical model for the behavior of RFID tags immersed in a dielectric medium using the Uda model and embedded T-match antenna. From this, we are able to investigate a number of criteria for optimality. We find that the simplest optimality condition is not physically realizable, and more realizable models yield several results that are of practical interest. Also, we propose a method to determine the input impedance of a center-fed dipole using a five element equivalent circuit. We relax the conditions for optimality and do an exhaustive search for the optimal design over the parametric space. Finally, we validate the model and present the trade-off to be made with the power transfer efficiency to obtain a tag working in wider range of dielectric materials. We make two specific recommendations for future work to increase the accuracy and usefulness of this work.
Two-Tier Architecture for Web Mapping with NoSQL Database CouchDB

Two of the greatest challenges of mobile data collecting applications are replication and synchronicity. This paper deals with these challenges and offers a new solution: two-tier architecture using CouchDB. CouchDB is a RESTful non-relational (NoSQL) document-oriented database with the ability to serve web pages directly from the database. CouchDB is acting as a web server and data storage on the server side and as a web browser on a client side. Although cloud functions on a mobile device can be used, the main advantage of CouchDB is the ability to work offline with both data and application, replicating the results back to the server. Combining such a solution with GPS we get simple mobile GIS data collector in a standard browser application. Many smartphones and mobile devices can be transformed to mobile data collectors with ease. In this paper, we will show the fundamental CouchDB concepts as a data and application storage.
Synthesis of Tic Thin Films by CVD from Toluene and Titanium Tetrachloride with Nickel as Catalyst

Titanium Carbide TiCx was deposited onto quartz substrates by the chemical vapour deposition (CVD) method. TiCx thin films were obtained from titanium tetrachloride (TiCl4) and toluene (C6H5CH3) as carbon source. Deposits were carried out in the range of substrate temperatures from 300 to 1100 C, with a source gas molar ratio (C6H5CH3/TiCl4 + C6H5CH3 ) of 0.8. There was two deposit processes; the first was to carry out without nickel as catalyst and the second with nickel as catalyst. Results showed that the effect of nickel as catalyst is very relevant to obtain TiCx. TiC0.87 thin films, 0.5 m thickness, were obtained for deposition temperatures above 900C using nickel as catalyst. In this case a cubic structure, with a lattice parameter of 4.327 A and a hardness of 2900 Vickers, was obtained at 11000C. whilst for substrate temperatures between 300 to 900°C with nickel as catalyst amorphous carbon samples were obtained. For the samples prepared without the presence of the nickel as catalyst only C amorphous thin films were obtained for all deposit temperatures.
Using Poly-L-Histidine Modified Glassy Carbon Electrode to Trace Hydroquinone in the Sewage Water

A sensitive voltammetric method for trace measurements of hydroquinone in the sewage water is described. The poly-L-histidine is prepared to modify the glassy carbon electrode in order to improve the electrochemical catalysis of interesting substances such as hydroquinone. The influence of the base solution, pH value, and scanning speed on the tracing of hydroquinone is discussed, and the experimental procedures and conditions are optimized. The laboratory results show that it is possible to construct a linear calibration curve between the peak current of hydroquinone on modified electrode and its concentration at the level of 0.00001 mol/L. The potential limitation of the method is suggested by a linear peaking shift model as well. The method was successfully applied to the determination of hydroquinone in the actual sample of industrial waste water.
Racial Disparities in School Suspension and Subsequent Outcomes: Evidence from the National Longitudinal Survey of Youth 1997

Using data from the National Longitudinal Survey of Youth 1997, I examine the prevalence and intensity of suspension among nationally representative samples of white, black, and Hispanic youth attending secondary school during the late 1990s and follow their educational and criminal justice outcomes for roughly a decade after K-12. Consistent with prior research in individual states and districts, I find that suspension has become a common feature of the U.S. schooling experience, affecting more than one in three youth and resulting in substantial missed instructional time across K-12 (a total of one to two weeks for the typical suspendee). As with prior research, disparities by race and gender are large, with black boys suspended most frequently and most intensely: fully two in three are suspended at some point during K-12, and nearly one in five is suspended for a full month of school or more. Following youth into early adulthood, I find that suspension is highly correlated with negative educational and criminal justice outcomes in the longer term. Among boys suspended for 10 total days or more, less than half had obtained a high school diploma by their late 20s; more than three in four had been arrested; and more than one in three had been sentenced to confinement in a correctional facility. Comparing suspension to self- reported behavior – including property offenses and violent behaviors – reveals that substantial shares of suspended youth had not engaged in serious delinquency by the time they were first suspended from school. In addition, racial and ethnic gaps in suspension persist after these serious misbehaviors are controlled. In light of these findings, policymakers interested in improving educational outcomes for all youth, ensuring equity across racial and ethnic groups, and increasing public safety should promote alternatives to suspension, identify and support schools with high rates of exclusionary discipline, and fund evaluations of recent efforts to limit the use of suspension and reduce racial disparities in districts across the U.S.
Valoración de la condición física saludable en adultos (y II) : fiabilidad, aplicabilidad y valores normativos de la batería AFISAL-INEFC

En este articulo se describen los estudios de fiabilidad y aplicabilidad, asi como de obtencion de valores normativos, de la bateria de valoracion de la condicion fisica saludable para adultos AFISAL-INEFC (Rodriguez et al. 1995a-c, 1998). El objetivo del primer estudio fue determinar la fiabilidad test-retest intraobservador de las pruebas que componen la bateria y su aplicabilidad en condiciones de campo. A tal efecto, la bateria fue aplicada en dos ocasiones en un intervalo de 15 dias a 30 adultos sanos (10 hombres y 20 mujeres, de 18 a 30 anos de edad). La bateria completa fue administrada a razon de 6 sujetos en 60 minutos por examinador. Los resultados no mostraron diferencias significativas entre la primera y la segunda realizacion de las pruebas (p> 0,05) y los indices de fiabilidad test-retest intraobservador pueden considerarse aceptables para pruebas de campo (CCI = 0,76-0,99). No se produjeron accidentes ni aparecieron sintomas fisicos relevantes en ningun sujeto durante o con posterioridad a la realizacion de las pruebas. En consecuencia, las pruebas de condicion fisica de la bateria AFISAL-INEFC de valoracion de la condicion fisica saludable pueden considerarse razonablemente fiables y aplicables en poblacion adulta sana. El objetivo del segundo estudio fue determinar los valores normativos de las pruebas que componen la bateria. Median-te un muestreo por accesibilidad, se evaluaron 238 sujetos sanos (102 hombres y 136 mujeres) utilizando el mismo protocolo. Se establecieron seis grupos segun edad para cada sexo (18-24; 25-34; 35-44; 45-54; 55-64; >64 anos). Para la elaboracion de los haremos se establecieron 5 categorias para cada grupo de edad y sexo, calculandose los intervalos correspondientes a cada categoria en base a las puntuaciones "z" de cada variable. Como conclusion, hasta disponer de un estudio de mayor alcance basado en una muestra mas amplia y seleccionada en forma aleatoria, parece adecuado utilizar los resultados del presente estudio como datos normativos de referencia provisionales para valorar la condicion fisica saludable mediante la bateria AFISAL-INEFC en poblacion catalana adulta.
Profitability as a criterion in key account selection -Evidence from a professional services organization (Available on Internet)

Business-to-business companies within the professional services sector tend to encounter fierce competition when aiming to win over the most distinguished customers. To avoid unprofitability, these companies need to put much consideration into prioritizing the right type of customers. However, there is not much academic literature published on customer prioritization, i.e. key account (KA) selection. The aim of the study is to measure the relationship between KA selection and customer account profitability when taking to account other KA selection criteria in a professional services organization. The study uses internal and external customer data that is obtained from a professional services organization. Several quantitative tests such as ANOVA and binary logistic regression were utilized in the study. Furthermore, AIC, BIC and likelihood ratio tests are used in order to make valid comparisons between models. The results show that there is a relationship between profitability and KA selection when profitability is measured in monetary terms. However, no relationship could be found when profitability is measured as a percentage. Further tests even indicate that profitability has not been used as a KA selection criterion, but instead is a by-product of the fact that KAs have bigger contracts and therefore provide higher account revenues. Furthermore, customer size, higher account revenue and a higher number of sales opportunities increase the odds of being selected as a KA, whereas a long business relationship does not.
Consequences of viscous anisotropy in a deforming, two-phase aggregate. Part 2. Numerical solutions of the full equations

Abstract In partially molten regions of Earth, rock and magma coexist as a two-phase aggregate in which the solid grains of rock form a viscously deformable framework or matrix. Liquid magma resides within the permeable network of pores between grains. Deviatoric stress causes the distribution of contact area between solid grains to become anisotropic; this, in turn, causes anisotropy of the matrix viscosity at the continuum scale. In the second of a two-paper set, we use numerical methods to solve the full, nonlinear, time-dependent equations governing this system. We consider porosity evolution in simple shear, Poiseuille and torsional flow. Under viscous anisotropy, there are two modes of porosity evolution: base-state segregation, which modifies the domain-scale porosity distribution, and growth of porosity perturbations into melt-rich bands. Simulation results with fixed anisotropy confirm and extend the linearized analysis of Part 1 (Takei & Katz, J. Fluid Mech., vol. 734, 2013, pp. 424–455). Most importantly, numerical solutions capture the interaction of the two modes: under Poiseuille flow, base-state segregation enhances band formation; under torsional flow, bands are suppressed. Simulations also show that low band angle is maintained by nonlinear processes such as reconnection of high-porosity segments and by back-rotation of the compacted regions between bands. Simulations with dynamic anisotropy modify these results, further lowering the average band angle. The effective viscosity of each flow is controlled by base-state segregation; it does not evolve under simple shear, decreases in Poiseuille flow and increases in torsion. We propose a reinterpretation of experimental results in terms of the consequences of viscous anisotropy.
A Study of Stochastic Resonance in the Periodically Forced Rikitake Dynamo

The geodynamo has widely been thought to be an intuitive and selfsustained model of the Earth’s magnetic field. In this paper, we elucidate how a periodic signal could be embedded in the geomagnetic filed via the mechanism of stochastic resonance in a forced Rikitake dynamo. Based on the stochastic resonance observed in the periodically forced Rikitake dynamo, we thus suggest a common triggering for geomagnetic reversal and glacial events. Both kinds of catastrophes may result from the cyclic variation of the Earth’s orbital eccentricity.
A SENSITIVITY ANALYSIS OF THE APPLICATION OF DYNAMIC PROGRAMMING TO PAVEMENT MANAGEMENT SYSTEMS

There has been a concerted research effort to update the prediction and optimization capabilities of the Micro PAVER pavement management system. An approach uniting the Markov probability prediction curves and dynamic programming optimization has been proposed. This paper briefly outlines the background work done on both. It examines the sensitivity of the dynamic programming output to changes in input parameters. Data from three existing databases and a fourth, formulated database are used in the analysis. Output values from dynamic programming are also compared with results obtained from deterministic analysis using best-fit curves for prediction and cost versus condition data. It is concluded that the dynamic programming results are reasonable. A multizone dynamic programming approach was seen to give more consistent results than a one-zone approach. It was found that for life-cycle lengths greater than 15 years, there was little change in optimal decision or cost. Low interest rates favored more expensive, longer-lasting solutions. The minimum Pavement Condition Index (PCI) level specified affected the results appreciably, in general. These results were consistent through all four databases examined. It was concluded that the Markov/dynamic programming approach was functioning satisfactorily, and was suitable and appropriate for use at the microcomputer level.
Electronic origin of the volume collapse in cerium

The cerium alpha-gamma phase transition is characterized by means of a many-body Jastrow-correlated wave function, which minimizes the variational energy of the first-principles scalar-relativistic Hamiltonian, and includes correlation effects in a non-perturbative way. Our variational ansatz accurately reproduces the structural properties of the two phases, and proves that even at temperature $T=0$K the system undergoes a first order transition, with ab initio parameters which are seamlessly connected to the ones measured by experiment at finite $T$. We show that the transition is related to a complex rearrangement of the electronic structure, with key role played by the p-f hybridization. The underlying mechanism unveiled by this work can hold in many Ce-bearing compounds, and more generally in other f-electron systems.
Electrochemical Impedance Spectroscopy for Corrosion Study

Cast iron water main failures have largely been as a result of corrosion damage that takes place when the metal is exposed in aggressive environment, resulting in gradual corrosion and loss of structural material and mechanical strength and ultimately leading to failure. In this study, Electrochemical impedance Spectroscopy (EIS) approach was used to determine polarization resistance of steel under various environments.
