ACCURACY OF MEASUREMENTS IN OBLIQUE AERIAL IMAGES FOR URBAN ENVIRONMENT

Abstract. Oblique aerial images have been a source of data for urban areas for several years. However, the accuracy of measurements in oblique images during this time has been limited to a single meter due to the use of direct -georeferencing technology and the underlying digital elevation model. Therefore, oblique images have been used mostly for visualization purposes. This situation changed in recent years as new methods, which allowed for a higher accuracy of exterior orientation, were developed. Current developments include the process of determining exterior orientation and the previous but still crucial process of tie point extraction. Progress in this area was shown in the ISPRS/EUROSDR Benchmark on Multi-Platform Photogrammetry and is also noticeable in the growing interest in the use of this kind of imagery. The higher level of accuracy in the orientation of oblique aerial images that has become possible in the last few years should result in a higher level of accuracy in the measurements of these types of images. The main goal of this research was to set and empirically verify the accuracy of measurements in oblique aerial images. The research focused on photogrammetric measurements composed of many images, which use a high overlap within an oblique dataset and different view angles. During the experiments, two series of images of urban areas were used. Both were captured using five DigiCam cameras in a Maltese cross configuration. The tilt angles of the oblique cameras were 45 degrees, and the position of the cameras during flight used a high grade GPS/INS navigation system. The orientation of the images was set using the Pix4D Mapper Pro software with both measurements of the in-flight camera position and the ground control points (measured with GPS RTK technology). To control the accuracy, check points were used (which were also measured with GPS RTK technology). As reference data for the whole study, an area of the city-based map was used. The archived results were referred to image orientation accuracy and to the ground sampling distance of the used images. The results show that the recent development of image orientation methods for oblique aerial images allow these images to be used for high quality photogrammetric measurements.
THE CHARACTERISTICS AND EVOLUTION OF THE BRAZILIAN SPATIAL URBAN SYSTEM: EMPIRICAL EVIDENCES FOR THE LONG-RUN, 1970-2010

In this paper we use spatial analysis and spatial econometrics methods to assess some empirical issues on the size distribution of the Brazilian Urban System. The main novelty is the long historical period of analysis which includes all the demographic censuses from 1940. More specifically, we describe the spatial distribution of the Brazilian cities, as well as its temporal evolution; we test test Zipf’s Law in its original and spatial version, and we use Markov Chains analysis in order to shed some light on the dynamics of the cities within the urban system. We introduce spatial dependence in both Zipf’s law estimation and Markov chain framework in order to capture the influence of the geographical environment on the relative position and mobility of the cities within the urban system. Our estimates for the Pareto coefficient were quite different for OLS and spatial models suggesting the inconsistency of OLS estimates in the non-spatial models. For the full sample of municipalities the Pareto coefficient is much smaller than 1, which features a polarized urban structure. Municipalities with urban population above the average show a less concentrated urban structure and seem to confirm Zipf law. Traditional Markov chain analysis indicates a high stability and low mobility inter-class over time confirming that, with rare exceptions, radical changes in urban population size are uncommon. Results for the Spatial Markov matrix show that municipalities with more populous neighbors are more likely to grow.
Strategic orientation and organizational forms: an integrative framework

Purpose – This paper aims to bring together strategic orientation (SO) and organizational forms literatures by proposing refined SO typologies based on various combinations of entrepreneurial orientation (EO) and market orientation (MO); and postulating typical organizational forms (configurations) for proposed SO types relative to each other in terms of parameters identified from organizational forms literature. Design/methodology/approach – This conceptual paper employs selective-intensive review of literature dealing with: both EO and MO to identify extant SO typologies, relevant strategic attributes, and relationships between EO, MO and strategic attributes; and organizational forms to identify parameters. Tabular frameworks are used to compare the proposed and extant SO types, posit strategic attributes for the proposed SO types, and compare ideal organizational profiles across SO types. Findings – EO and MO are related constructs that capture distinct aspects of business philosophy. Relationships of.
Lipids contribute to epigenetic control via chromatin structure and functions

Abstract Isolated cases of experimental evidence over the last few decades have shown that, where specifically tested, both prokaryotes and eukaryotes have specific lipid species bound to nucleoproteins of the genome. In vitro, some of these lipid species exhibit stoichiometric association with DNA polynucleotides with differential affinities toward certain secondary and tertiary structures. Hydrophobic interactions with inner nuclear membrane could provide attractive anchor points for lipid-modified nucleoproteins in organizing the dynamic genome and accordingly there are precedents for covalent bonds between lipids and core histones and, under certain conditions, even DNA. Advances in biophysics, functional genomics, and proteomics in recent years brought about the first sparks of light that promises to uncover some coherent new level of the epigenetic code governed by certain types of lipid–lipid, DNA–lipid, and DNA-protein–lipid interactions among other biochemical lipid transactions in the nucleus. Here, we review some of the older and more recent findings and speculate on how critical nuclear lipid transactions are for individual cells, tissues, and organisms.
History and Civil Conflict

How much does the antiquity of states, and the sometimes arbitrary nature of colonial boundaries, explain why some states are more susceptible to civil conflict than others? Older states and those with greater historical legitimacy (more continuity between the pre-colonial and post-colonial state) have less ethnic diversity. Controlling for a lack of historical legitimacy, ethnic polarization adds to the risk of conflict, but a short history of statehood does not. The degree of political organization of ethnic groups or their exclusion from political power does not significantly affect the risk of conflict.
Numerical rigid plastic modelling of shear capacity of keyed joints

Keyed shear joints are currently designed using simple and conservative design formulas, yet these formulas do not take the local mechanisms in the concrete core of the joint into account. To investigate this phenomenon a rigid, perfectly plastic finite element model of keyed joints is used. The model is formulated for second-order conic optimisation as a lower bound problem, which yields a statically admissible stress field that satisfies the yield condition in every point. The dual solution to the problem can be interpreted as the collapse mode and will be used to analyse the properties of the different joints. This approach makes it possible to investigate both global and local failure mechanisms in keyed joints. The results of the model will be compared to experiments found in the literature as well as the current design rules of the Eurocode.
Improving the mobility of severely disabled

A modular mobility aid system is presented, which can be attached to most commercial electric wheelchairs to increase the independence and safety of the wheelchair user. The system consists of falling avoidance, obstacle avoidance, and beaconless navigation functions. Experiences from an evaluation period are presented. Also an idea is presented to combine map information to environmental perceptions in order to provide the wheelchair user a better awareness of his/her whereabouts. The navigation system can also be applied to different mobile robot applications.
Contribution of dietary bacteria to metal accumulation in the slipper limpet

Recent studies have shown that dietary ingestion can be an important source for metal accumulation in aquatic animals. Whether bacteria can contribute significantly to the overall metal accumulation in these animals remains little known. In this study, we used the kinetic modeling approach to examine the relative contribution of the aqueous phase, bacteria, and phytoplankton, as sources for Cd, Cr, and Zn accumulation by the slipper limpet Crepidula onyx, a suspension feeder that can capture bacteria efficiently. Metal uptake rate constants measured in C. onyx were 0.200, 1.232, and 1.294 l g–1 d–1 for Cd, Cr, and Zn, respectively. The assimilation efficiency (AE) of metals from ingested phytoplankton (11 to 44% for Cd, and 31 to 41% for Zn) was comparable to AEs of metals from ingested bacteria (21 to 42% for Cd, 35 to 47% for Zn), whereas the AEs of Cr from ingested phytoplankton (10 to 22%) were lower than from ingested bacteria (44 to 59%). The AEs of Cr from different phytoplankton and bacterial diets were related to its distribution in the cytoplasm of cells and its passage time across the animal’s guts. The limpets filtered the bacteria at rates (17 l h–1 g–1) 1.3 to 1.9× lower than the filtration rate on different phytoplankton diets (22 to 33 l h–1 g–1). The estimated average bioconcentration factors of metals by 2 bacterial strains were 2 to 6 × 105 for Cd, 1 to 7 × 105 for Cr, and 1.5 to 7 × 105 for Zn. The kinetic model predicted that uptake from dietary phase dominated metal accumulation in the slipper limpets (87% for Cd, 72% for Cr, and 83% for Zn). Ingestion of bacteria contributed 23% for Cd, 27% for Cr, and 17% for Zn accumulation in the limpets under typical conditions for the limpets. Our study therefore highlights bacteria as a potentially important source of metal accumulation in this filter-feeding mollusc.

Comparative study on various PWM Strategies for Novel Multilevel Inverter

Multilevel Inverters offer high power capability, associated with lower output harmonics. This paper presents the performance analysis of new symmetrical multilevel inverter using different PWM strategies based on control freedom degree approach. These PWM strategies include carrier overlapping, variable frequency, phase disposition and phase opposition disposition pulse width modulation. The total harmonic distortion, VRMS , Crest factor and Form factor are evaluated for various modulation indices. Simulations were performed using MATLAB-SIMULINK. It is observed that PODPWM strategy provide output with relatively low distortion and COPWM is found to perform better since it provides higher fundamental RMS output voltage.
Heteroscedasticity and interval effects in estimating beta: UK evidence

The article compares beta estimates obtained from Ordinary Least Squares (OLS) regression with estimates corrected for heteroscedasticity of the error term using Autoregressive Conditional Heteroscedasticity (ARCH) models, for 145 UK shares. The differences are mainly less than 0.10, for betas calculated using daily returns, but even such small differences can matter in practice. OLS tends to overestimate the beta coefficients compared with ARCH models, and selecting an ARCH type estimate makes the most difference for large cap shares. Regarding the measurement interval, the downward bias in betas from daily returns is associated with not only thin trading but also the volatility of the share's daily returns. We infer that the idiosyncratic component in daily returns, as well as lack of trading, is responsible for low daily betas.
Responding to Climate Change: The Contribution of Maharishi Vedic Science

The scope and reach of the climate change challenge is clearly unprecedented, as is its level of global urgency. We review the broad results of the scientific program associated with it. These results identify serious impacts on physical, biological, and human systems, as separate systems and as cascading through them. The global risks associated with these impacts are daunting. Modern analytic approaches to this order of complexity and uncertainty have so far made only a limited contribution to its understanding and resolution. In particular these approaches identify a crucial gap: the understanding and modelling of the whole, rather than the parts, of the system. We then advance the promise of Maharishi Vedic Science in providing this missing scientific knowledge, in principle and in practice. In particular we explore a model offered by Maharishi Vedic Science which describes eight levels of Natural Law to embrace all the complex diverse systems of which the global climate system is comprised. Further we review the technologies through which Maharishi Vedic Science offers to restore balance, integration and orderly growth to all systems from their foundation in the Unified Field of Natural Law. We outline the extensive scientific research program which has provided robust support for the predictions of Maharishi Vedic Science with respect to both individual and collective life; which extend, we suggest, to the global community and to the global challenge of climate change.
How pre-start up assessment helps software companies in Agile transition

While prevalence of Agile methodologies is increasing these years, companies should be aware of challenges that may they face during changing their development approach. Agile methods focus on people and this makes transition process more difficult than people expect. Companies should be ready for Agile transition, and performing a pre-start up assessment may help them to be best prepared for the change. Conducting a Grounded Theory study involving 33 Agile experts from 13 different countries showed that pre-start up assessment can help companies in various aspects including defining business goals, addressing training needs, team set up, pilot project selection and method or practice selection. In pre-start up assessment organization and team members should be evaluated to discover their abilities, requirements and restrictions. This process helps companies to get ready for moving to Agile.

Orbital character variation of the Fermi surface and doping dependent changes of the dimensionality in BaFe2−xCoxAs2 from angle-resolved photoemission spectroscopy

From a combination of high resolution angle-resolved photoemission spectroscopy and density functional calculations, we derive information on the dimensionality and the orbital character of the electronic states of BaFe2−xCoxAs2. Upon increasing Co doping, the electronic states in the vicinity of the Fermi level take on increasingly three-dimensional character. Both the orbital variation with kz and the more three-dimensional nature of the doped compounds have important consequences for the nesting conditions and thus possibly also for the appearance of antiferromagnetic and superconducting phases.
Assesssing the prospective resource base for enhanced geothermal systems in Europe

In this study the resource base for EGS (enhanced geothermal systems) in Europe was quantified and economically constrained, applying a discounted cash-flow model to different techno-economic scenarios for future EGS in 2020, 2030, and 2050. Temperature is a critical parameter that controls the amount of thermal energy available in the subsurface. Therefore, the first step in assessing the European resource base for EGS is the construction of a subsurface temperature model of onshore Europe. Subsurface temperatures were computed to a depth of 10 km below ground level for a regular 3-D hexahedral grid with a horizontal resolution of 10 km and a vertical resolution of 250 m. Vertical conductive heat transport was considered as the main heat transfer mechanism. Surface temperature and basal heat flow were used as boundary conditions for the top and bottom of the model, respectively. If publicly available, the most recent and comprehensive regional temperature models, based on data from wells, were incorporated With the modeled subsurface temperatures and future technical and economic scenarios, the technical potential and minimum levelized cost of energy (LCOE) were calculated for each grid cell of the temperature model. Calculations for a typical EGS scenario yield costs of EUR 215 MWh-1 in 2020, EUR 127 MWH-1 in 2030, and EUR 70 MWh-1 in 2050 are imposed to the calculated LCOE values in each grid cell to limit the technical potential, resulting in an economic potential for Europe of 19GWe in 2020, 22GWe in 2030, and 522GWe in 2050. The results of our approach do not only provide an indication of prospective areas for future EGS in Europe, but also show a more realistic cost determined and depth-dependent distribution of the technical potential by applying different well cost models for 2020, 2030, and 2050

Also, in order to deliver the current foodservice education, food and beverage management programs must respond to the changes in industry and the needs of students. The purpose of this paper is to identify the students’ expectations and satisfaction of food and beverage management course that more accurately reflects the learning experiences appropriate for students entering the food and beverage industry.
Adaptation to statistical properties of visual scenes biases rapid categorization

The initial categorization of complex visual scenes is a very rapid process. Here we find no differences in performance for upright and inverted images arguing for a neural mechanism that can function without involving high-level image orientation dependent identification processes. Using an adaptation paradigm we are able to demonstrate that artificial images composed to mimic the orientation distribution of either natural or man-made scenes systematically shift the judgement of human observers. This suggests a highly efficient feedforward system that makes use of “low-level” image features yet supports the rapid extraction of essential information for the categorization of complex visual scenes.
Statistical methods for large portfolio risk management

Portfolio allocation is one of the most important problems in financial risk management. It involves dividing an investment portfolio among different assets based on the volatilities of the asset returns. In the recent decades, it gains popularity to estimate volatilities of asset returns based on highfrequency data in financial economics. In this article, we focus on the portfolio allocation problem using high-frequency financial data. The paper starts with a review on portfolio allocation and high-frequency financial time series. Then we introduce a new methodology to carry out efficient asset allocations using regularization on estimated integrated volatility via intra-day high-frequency data. We illustrate the methodology by comparing the results of both lowfrequency and high-frequency price data on stocks traded in the New York Stock Exchange in 2011. The numerical results show that portfolios constructed using high-frequency approach generally perform well by pooling together the strengths of regularization and estimation from a risk management perspective.
