The Effect of Geographical Information Systems on a Collaborative Command and Control Task

This paper tests the claimed benefits of using geographical information systems (GIS) in emergency response operations. An experimental study comparing command teams using GIS and paper-based maps is presented. The study utilized a combined approach using microworld simulations together with physical artefacts. Participants in the experiment took the role of command teams, facing the task of extinguishing a simulated forest fire. A total of 132 persons, forming 22 teams, participated in the study. In eleven of the teams, the participants were given access to GIS with positioning of fire-brigades as well as sensor data about the fire outbreak. In the other eleven teams, the participants were using paper-based maps. The result shows that teams using GIS performed significantly better than teams with paper-based maps in terms of saved area. Communication volume was considerably reduced in the case of GIS teams. Implications of these results on GIS are discussed as well as methodological considerations for future research.
Relação entre Ibovespa e Variáveis Macroeconômicas: Evidências a Partir
 de um Modelo Markov-Switching

This paper examined if macroeconomic variables individually have long-term relationship with Brazilian stock return rates, where the Ibovespa. For this, we applied the Markov-switching dynamic model with change in variance, between macroeconomic variable, selected from the literature, and the Ibovespa, were applied, partially, the methodology used by Chen (2009). It was observed that the money supply, economic activity, interest rate, level of imports and exports and exchange rate have a long-term relationship with Ibovespa. However, this relationship was not verified for the inflation rate. It was also verified that the variables supply of money, economic activity, level of import and export, while the interest rate and exchange rate are positively related to the market return.
In Vitro Evaluation of Mechanical Heart Valve Performance Using a Novel Test Chamber in an Automated Mock Circulatory Loop

IN VITRO EVALUATION OF MECHANICAL HEART VALVE PERFORMANCE USING A NOVEL TEST CHAMBER IN AN AUTOMATED MOCK CIRCULATORY LOOP By Antonio R. Walker, B.S. in Biomedical Engineering A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Biomedical Engineering at Virginia Commonwealth University. Virginia Commonwealth University, 2010 Director: Gerald E. Miller, Ph.D. Department Chair of Biomedical Engineering Valvular heart disease (VHD) continues to have significant effects on many people’s lives, with numbers expected to grow tremendously over the next few years. Individuals suffering from severe valvular heart disease usually require a heart valve transplant in order to restore the native valve’s vital unidirectional flow regulation. Therefore, artificial heart valve (AHV) research is of very high importance. Previous research studies have provided substantial input in the realm of AHV design relative to durability, thrombotic and hemolytic potential, and overall functionality. However, modifications continue to be warranted due to limitations in the accuracy and time efficiency of the in vitro physiological flow replication process. The objective of this investigation is to develop and analyze a method of AHV performance evaluation using a novel
Contribution of orofacial somatosensory inputs to speech perception in noise

Background: Speech perception is an interactive process with multiple sensory modalities and probably some perceptuo-motor connections(Schwartz et al., 2012). Particularly seeing the talker’s face helps better understanding of speech sounds in speech communication in noisy environment (Sumby and Pollack, 1954). This idea was further demonstrated by showing that the detection threshold of speech sentences in noise was improved by visual stimulation concerning rhythmic information related to the presented sentences (Aubanel et al., 2017). In contrast to the focus of audio-visual interactions, recent findings of an orofacial somatosensory influence on the perception of speech sounds (Ito et al., 2009) suggest a potential role for the somatosensory system in speech processing. However, it is still unknown whether somatosensory inputs help to perceive speech sounds in noisy environment. Exploring possible influence of somatosensory inputs on speech perception in noise could provide new insights about the linkage between speech production and perception, and lead to potential interesting applications in speech learning.
Unemployment Hysteresis and Capacity

This paper examines an open economy model in which equilibrium unemployment depends on capacity in the traded-goods sector. The model is estimated using U.K. quarterly data and compared with alternative concepts of equilibrium unemployment based on labour market variables (as in Layard and Nickell, 1986) or on the price of oil and the real interest rate (as in Carruth, Hooker and Oswald, 1998). The capacity model displays a non-linear hysteresis mechanism through which capacity utilisation and the degree of volatility of the real exchange rate interact to generate changes in equilibrium unemployment. This is modelled as logistic smooth transition autoregressive (LSTAR) process.

LAYOUT OF HYPERSONIC VEHICLES BY COUPLING OF AERODYNAMICS AND FLIGHTMECHANICS

Currently, the direct coupling of CFD and flight mechanics during the layout is still much too time-consuming to consider the free motion of a vehicle along a complete trajectory. Therefore, it is the goal to develop a modular coupling procedure between the trajectory optimization code REENT [1] of the Universitat Stuttgart and the DLR surface inclination method SOSE [2], which in a later step also allows the use of the DLR Euler- and Navier- Stokes code TAU. Within the present paper the coupling procedure is introduced and basic but representative examples for sounding rocket and re-entry missions are discussed to prove the feasibility of the procedure.
Forecasting Crude Oil Price Using Event Extraction

Research on crude oil price forecasting has attracted tremendous attention from scholars and policymakers due to its significant effect on the global economy. Besides supply and demand, crude oil prices are largely influenced by various factors, such as economic development, financial markets, conflicts, wars, and political events. Most previous research treats crude oil price forecasting as a time series or econometric variable prediction problem. Although recently there have been researches considering the effects of real-time news events, most of these works mainly use raw news headlines or topic models to extract text features without profoundly exploring the event information. In this study, a novel crude oil price forecasting framework, AGESL, is proposed to deal with this problem. In our approach, an open domain event extraction algorithm is utilized to extract underlying related events, and a text sentiment analysis algorithm is used to extract sentiment from massive news. Then a deep neural network integrating the news event features, sentimental features, and historical price features is built to predict future crude oil prices. Empirical experiments are performed on West Texas Intermediate (WTI) crude oil price data, and the results show that our approach obtains superior performance compared with several benchmark methods.
Feasibility of a Remotely Delivered Strength and Balance Training Program for Older Adults with Cancer

Falls are a major issue among older adults with cancer and lead to interruptions in cancer treatment. Resistance and balance training can prevent falls in older adults, but minimal evidence is available regarding the older cancer population, who often have unique risk factors. We used a pre–post design to assess the feasibility of a remotely delivered exercise program that progressed in difficulty and its efficacy on lower body strength, balance, and falls in older adults with cancer who had prior in-person exercise experience. Twenty-six older adults with cancer completed the intervention. Attendance rate for the virtual component was 97.6% and for the independent component was 84.7%. Participants perceived the program as rewarding and enjoyable (100%), felt this program prepared them to exercise on their own (92%), were confident to continue exercising on their own (81%), and would recommend the program to other patients (100%). The median balance score at baseline and end-of-study was 4 (IQR = 0). The median chair-stand time decreased from 9.2 s (IQR = 3.13) to 7.7 s (IQR = 4.6). A statistically significant difference in lower body strength (r = 0.68, p = 0.001) was detected post-intervention. The findings from this study can inform the design of a larger randomized trial.
Electro-Oxidation in Combination with Biological Processes for Removal of Persistent Pollutants in Wastewater: A Review

Persistent organic pollutants (POPs) and emerging pollutants (EP) are characterized by their difficulty to be removed through biological oxidation processes (BOPs); they persist in the environment and could have adverse effects on the aquatic ecosystem and human health. The electro-oxidation (EO) process has been successfully used as an alternative technique to oxidize many kinds of the aforementioned pollutants in wastewater. However, the EO process has been criticized for its high energy consumption cost and its potential generation of by-products. In order to decrease these drawbacks, its combination with biological oxidation processes has been reported as a solution to reduce costs and to reach high rates of recalcitrant pollutants removal from wastewaters. Thus, the location of EO in the treatment line is an important decision to make, since this decision affects the formation of by-products and biodegradability enhancement. This paper reviews the advantages and disadvantages of EO as a pre and post-treatment in combination with BOPs. A perspective of the EO scaleup is also presented, where hydrodynamics and the relationship of A/V (area of the electrode/working volume of the electrochemical cell) experiments are examined and discussed.
Accelerated Corrosion Tests in Quality Labels for Powder Coatings on Galvanized Steel—Comparison of Requirements and Experimental Evaluation

Powder coatings are widely applied for corrosion protection of steel, aluminum, and hot dip galvanized steel in a variety of corrosive environments. Powder coatings are subjected to a number of strict laboratory tests to determine their mechanical properties, corrosion resistance, and color stability. Among European quality certificates for powder coatings applied to galvanized steel, the most commonly recognized are GSB-ST and Qualisteelcoat certificates, which also refer to the EN 13438 standard. Certificates of quality for powder coatings are constantly updated according to the latest research results and experience of specialists operating in the field of corrosion protection. This paper presents an experimental evaluation of how the required length of selected accelerated corrosion tests can affect the final assessment of powder coatings. On the example of two powder painting systems: polyester as well as based on epoxy and polyester resins, the paper presents the influence of the time of accelerated corrosion tests: ISO 6270, ISO 9227 (Neutral Salt Spray and Acetic Acid Salt Spray), and ISO 3231 on the protective properties of the coatings. The results of damage assessment according to ISO 4628 have been correlated with the requirements of particular quality specifications. Additionally, based on FTIR (Fourier Transform Infrared Spectroscopy) and EIS (Electrochemical Impedance Spectroscopy) analyses, the influence of the applied corrosion tests on the degradation degree of the coatings studied has been presented. The paper aims to present a tests for those powder coating systems applied to facilities for which the main requirement is corrosion resistance rather than aesthetics.
Arbitragem Estatística: Uma Abordagem por VECM

This work develops a statistical arbitrage model which was tested on the Brazilian stock market. Prices were modeled using VECM (Vector Error Correction Models) to create a self-financing, market-neutral, long/short trading strategy. In this strategy, deviations in the long-term equilibrium of prices are identified in order to create buy and sell signals. Portfolios with common trends were selected by means of Principal Component Analysis. The viability of this strategy was empirically addressed using simulations on these portfolios. Its performance was also compared to other long/short trading strategies and were all analyzed in terms of returns, volatility and statistical arbitrage opportunities. The methodology used in this paper shows good results for modeling prices, and though all trading strategies offer considerable gains for the investor, the proposed strategy stands out by presenting statistical arbitrage.
Continuous Integration - A comparison between theory and practice

To develop software in a larger scale, some kind of software development method is needed to organize the development. Many different software development methods have emerged since the beginning of software development, and Continuous Integration (CI) is one of them. Many companies have applied, or tried to apply CI in their business. Some companies were successful, some were not. This thesis examines what CI is in the theory, and compare it to how it works in the practice in the department ”Product Development Traffic Control” (PD TC) which is a part of the ”Product Development Unit LTE Multistandard Radio” (PDU LMR) within Ericsson. The theory of CI is examined mostly through literature studies. CI in practice was examined through interviews with developers and employees working with the CI-machinery at PD TC. The comparison between the theory and the studied company revealed that it is difficult to adapt CI perfectly to a large organization. This does not imply that CI is implemented in the wrong way, but the benefits of implementing CI in large projects may not be as enormous in comparison with smaller projects.
Geochemical Characteristics of Expelled and Residual Oil from Artificial Thermal Maturation of an Early Permian Tasmanite Shale, Australia

Lipid biomarkers play an important role in defining oil-source rock correlations. A fundamental assumption is that composition (or ratios) of biomarkers in oil is not significantly different from that in bitumen in the source rock. In order to compare the geochemical characteristics of expelled oil and residual oil, a Permian Tasmanite oil shale was used for an artificial maturation experiment to simulate the oil generation period. The results show that the Tasmanite oil shale generated high amounts of hydrocarbons (731 mg HC/g TOC) at low maturation temperatures (340 °C). The hydrocarbon (HC) group compositions are different between the expelled oil (with more aromatic HC and saturated HC) and the residual oil (with more resin fraction and asphaltene). The Pr/Ph ratio (up to 4.01) of the expelled hydrocarbons was much higher than that in residual oil (<1.0). Maturity-related biomarkers Ts/(Ts + Tm), and αααC29-20S/(20S + 20R) and C29-αββ/(ααα + αββ), also showed complicated variations with pyrolysis temperature, especially at post peak oil generation. C27-, C28-, and C29- sterane distributions showed variations with pyrolysis temperature. Therefore, without considering the influence of maturity on the abundance of compounds, either source, maturity and/or organic matter type from the chemical characteristics may not be correct.
Analytical Modeling of Axi-Symmetric Sheet Metal Forming

The cup drawing is a basic deep drawing process. Thus, understanding the mechanics of the cup drawing process helps in determining the general parameters that affect the deep drawing process. There are mainly two methods of analysis; experimental and analytical/numerical. Experimental analysis can be useful in analyzing the process to determine the process parameters that produce a defect free product. However, experimental work is usually very expensive and time consuming to perform. On the other hand, the Analytical/Numerical modeling can be used to model and analyze the process through all stages of deformation. This approach is less time consuming and more economical than experimental analysis. There have been several efforts to solve and analyze the deep drawing problem. Among these are the attempts to analyze the cup drawing process, by few researches who developed analytical models for the cup drawing process to solve for stresses and strains over the deforming sheet metal. However, they did not explain how to determine the moving boundaries in the deforming sheet. This paper deals with the analysis of deep drawing of circular blanks into axi-symmetric cylindrical cups forming using numerical modeling. A rigid plastic material model with the variational approach is used for this analysis. The amount of draw obtainable in the drawing process has been related both theoretically and experimentally with the initial diameter of the blank. The strains in the radial and circumferential directions have been measured. A correlation on the flange thickness variation by taking into account the work hardening with the analytical and experimental values also has been arrived at.

BERTODIA: BERT PRE-TRAINING FOR LOW RESOURCE ODIA LANGUAGE

Odia language is one of the 30 most spoken languages in the world. It is spoken in the Indian state called Odisha. Odia language lacks online content and resources for natural language processing (NLP) research. There is a great need for a better language model for the low resource Odia language, which can be used for many downstream NLP tasks. In this paper, we introduce a Bert-based language model, pre-trained on 430’000 Odia sentences. We also evaluate the model on the well-known Kaggle Odia news classification dataset (BertOdia: 96 %, RoBERTaOdia: 92 %, and ULMFit: 91.9 % classification accuracy), and perform a comparison study with multilingual Bidirectional Encoder Representations from Transformers (BERT) supporting Odia. The model will be released publicly for the researchers to explore other NLP tasks.
Enamel.

The aim of this study was to test whether dental fluorosis can be produced by administration of chronic doses offluoride during only the post-secretory stage of enamel mineralization. Eight control and eight experimental pigs matched by weight and litter were fed a lowfluoride diet (<0.05 mg F-/kg b.w. daily) from weaning to slaughter at 14 months. The test group received an oral dose of 2 mg F/kg b.w. per day from 8 months of age. Lowerfourth pre-molars were at the post-secretory stage at the start offluoride administration (confirmed by tetracycline marker) and were just erupting at slaughter. All of the fourth pre-molar teethfrom the test group developed diffuse enamel hypomineralization indistinguishable from human fluorosis. No such lesions were seen in any of the teethfrom the control animals. It was concluded that enamel fluorosis may be caused by fluoride exposure in the maturation phase only. The pathogenic mechanism may be an effect either on the selective loss ofprotein or on the influx of mineral, both of which occur during the post-secretory or maturation stage of enamel formation.
Modelling and analysis of cutting forces while micro end milling of Ti-alloy using finite element method

Micromilling is one of the preferable micro-manufacturing process, as it exhibits the flexibility to produce complex 3D micro-parts. The cutting forces generated in micro end milling can be attributed for tool vibration and process instability. If cutting forces are not controlled below critical limits, it may lead to catastrophic failure of tool. Cutting force has a significant role to decide the surface roughness. Therefore accurate prediction of cutting forces and selection of suitable cutting parameters mainly feed, is important while micro end milling. In present study, finite element method (FEM) based model has been developed by using ABAQUAS/Explicit 6.12 software. Von-Misses stresses and cutting forces are predicted while micro end milling of Ti-6Al-4V. Further, cutting forces were measured during experimentation using dynamometer mounted on micro-milling test bed. Cutting forces predicted by FEM model are in good agreement with the experimental force values. Obtained FEM results have been used to study the size effect in micro end milling process. Moreover, the effect of uncut chip thickness to cutting edge radius ratio (h/rc) on surface roughness (Ra) has been studied. It is found the feed 2.5 µm/tooth is suitable value to produce optimum surface roughness and cutting forces.
