CCAF-DB: the Caribbean and Central American active fault database
Authors: Styron Richard , García-Pelaez Julio , Pagani Marco
Published: March 2020

Abstract. A database of ∼250 active fault traces in the Caribbean and
Central American regions has been assembled to characterize the seismic hazard and tectonics of the area, as part of the Global Earthquake Model (GEM) Foundation's Caribbean and Central American Risk Assessment (CCARA) project. The dataset is available in many vector
GIS formats and contains fault trace locations as well as attributes describing fault geometry and kinematics, slip rates, data quality and uncertainty, and other metadata as available. The database is public and open source (available at: https://github.com/GEMScienceTools/central_am_carib_faults, last access: 23 March 2020), will be updated progressively as new data become available, and is open to community contribution. The active fault data show deformation in the region to be centered around the
margins of the Caribbean plate. Northern Central America has sinistral and
reverse faults north of the sinistral Motagua–Polochic fault zone, which
accommodates sinistral Caribbean–North American relative motion. The Central Highlands in Central America extend east–west along a broad array of normal faults, bound by the Motagua–Polochic fault zone in the north and trench-parallel dextral faulting in the southwest between the Caribbean plate and the Central American forearc. Faulting in southern Central America is complicated, with trench-parallel reverse and sinistral faults. The northern Caribbean–North American plate boundary is sinistral off the shore of Central America, with transpressive stepovers through Jamaica, southern Cuba and Hispaniola. Farther east, deformation becomes more contractional closer to the Lesser Antilles subduction zone, with minor extension and sinistral shear throughout the upper plate, accommodating oblique convergence of the Caribbean and North American plates.

Published: March 2020

Abstract. The ocean component and coastal impacts of Storm Gloria, that hit the Western Mediterranean between January 20th and 23rd 2020 are investigated with a numerical simulation of the storm surges and wind-waves. Storm Gloria caused severe damages and beat several historical records such as significant wave height or 24-h accumulated precipitation. The storm surge developed along the eastern coasts of the Iberian Peninsula reached values up to 1 m, and were accompanied by wind-waves with significant wave height up to 8 m. Along the coasts of the Balearic Islands, the storm footprint was characterised by a negligible storm surge and the impacts were caused by large waves. The comparison to historical records reveals that Storm Gloria is one of the most intense among the events in the region during the last decades and that the waves direction was particularly unusual. Our simulation permits quantifying the role of the different forcings in generating the storm surge. Also, the high spatial grid resolution down to 30 m over the Ebro Delta, allows determining the extent of the flooding caused by the storm surge. We also simulate the overtopping caused by high wind waves that affected a rocky coast of high cliffs (~ 15 m) in the eastern coast of Mallorca Island.
Applications of matrix factorization methods to climate data
Authors: Harries Dylan , O'Kane Terence J.
Published: March 2020

Abstract. An initial dimension reduction forms an integral part of many analyses in climate science. Different methods yield low-dimensional representations that are based on differing aspects of the data. Depending on the features of the data that are relevant for a given study, certain methods may be more suitable than others, for instance yielding bases that can be more easily identified with physically meaningful modes. To illustrate the distinction between particular methods and identify circumstances in which a given method might be preferred, in this paper we present a set of case studies comparing the results obtained using the traditional approaches of EOF analysis and k-means clustering with the more recently introduced methods such as archetypal analysis and convex coding. For data such as global sea surface temperature anomalies, in which there is a clear, dominant mode of variability, all of the methods considered yield rather similar bases with which to represent the data, while differing in reconstruction accuracy for a given basis size. However, in the absence of such a clear scale separation, as in the case of daily geopotential height anomalies, the extracted bases differ much more significantly between the methods. We highlight the importance in such cases of carefully considering the relevant features of interest, and of choosing the method that best targets precisely those features so as to obtain more easily interpretable results.
Current estimates of K1* and K2* appear inconsistent with measured CO2 system parameters in cold oceanic regions
Authors: Sulpis Olivier , Lauvset Siv K. , Hagens Mathilde
Published: March 2020

Abstract. Seawater absorption of anthropogenic atmospheric carbon dioxide (CO2) has led to a range of changes in carbonate chemistry, collectively referred to as ocean acidification. Stoichiometric dissociation constants used to convert measured carbonate system variables (pH, pCO2, dissolved inorganic carbon, total alkalinity) into globally comparable parameters are crucial for accurately quantifying these changes. The temperature and salinity coefficients of these constants have generally been experimentally derived under controlled laboratory conditions. Here, we use field measurements of carbonate system variables taken from the Global Ocean Data Analysis Project version 2 and the Surface Ocean CO2 Atlas databases to evaluate the temperature dependence of the carbonic acid stoichiometric dissociation constants. By applying a novel iterative procedure to a large dataset of 948 surface-water, quality-controlled samples where four carbonate system variables were independently measured, we show that the set of equations published by Lueker et al. (2000), currently preferred by the ocean acidification community, overestimates the stoichiometric dissociation constants at low temperatures, below ~ 8 °C. We apply these newly derived temperature coefficients to high-latitude Argo float and cruise data to quantify the effects on surface-water pCO2 and calcite saturation states. These findings highlight the critical implications of uncertainty in stoichiometric dissociation constants for future projections of ocean acidification in polar regions, and the need to improve knowledge of what causes the CO2 system inconsistencies in cold waters.
Prediction of monthly Arctic sea ice concentrations using satellite and reanalysis data based on convolutional neural networks

Published: March 2020

Abstract. Changes in Arctic sea ice affect atmospheric circulation,
ocean current, and polar ecosystems. There have been unprecedented decreases
in the amount of Arctic sea ice due to global warming. In this study, a novel 1-month sea ice concentration (SIC)
prediction model is proposed, with eight predictors using a deep-learning
approach, convolutional neural networks (CNNs). This monthly SIC prediction
model based on CNNs is shown to perform better predictions (mean absolute
error – MAE – of 2.28 %, anomaly correlation coefficient – ACC – of 0.98, root-mean-square error – RMSE – of 5.76 %, normalized RMSE – nRMSE – of 16.15 %,
and NSE – Nash–Sutcliffe efficiency – of 0.97) than a random-forest-based (RF-based) model (MAE of 2.45 %, ACC
of 0.98, RMSE of 6.61 %, nRMSE of 18.64 %, and NSE of 0.96) and the
persistence model based on the monthly trend (MAE of 4.31 %, ACC of 0.95,
RMSE of 10.54 %, nRMSE of 29.17 %, and NSE of 0.89) through hindcast
validations. The spatio-temporal analysis also confirmed the superiority of
the CNN model. The CNN model showed good SIC prediction results in extreme
cases that recorded unforeseen sea ice plummets in 2007 and 2012 with RMSEs of less
than 5.0 %. This study also examined the importance of the input
variables through a sensitivity analysis. In both the CNN and RF models, the
variables of past SICs were identified as the most sensitive factor in
predicting SICs. For both models, the SIC-related variables generally
contributed more to predict SICs over ice-covered areas, while other
meteorological and oceanographic variables were more sensitive to the
prediction of SICs in marginal ice zones. The proposed 1-month SIC
prediction model provides valuable information which can be used in various
applications, such as Arctic shipping-route planning, management of the fishing
industry, and long-term sea ice forecasting and dynamics.
EVALUATION OF RHEOLOGICAL PROPERTIES OF RUBBER COMPOUNDS BASED ON NR BY DETERMINATION OF NR LIPID CONTENTS OBTAINED FROM ATTENUATED TOTAL REFLECTION FOURIER TRANSFORM INFRARED SPECTRA

Published: March 2020

This work was done in three stages. In step 1, the lipid content of different natural rubbers (NRs) was evaluated by two methods, extraction and attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy, and the obtained results were successfully correlated. In the second step, the correlations between scorch time (Ts2) and optimum cure time (T′c90) of rubber compounds based on natural rubber (NR) and the lipid contents of different types of NR (obtained by two methods) were investigated. The suitable linear behaviors were observed. In the third step, because ATR-FTIR spectroscopy is a fast, simple, and nondestructive technique for characterizing NR, the correlations that were obtained by this method were considered to predict the rheological properties of two case studies. The amounts of Ts2 and T′c90 were estimated by errors of about 20% and 15%, respectively. This new approach is a nondestructive and rapid method for predicting the cure characteristics of the defined NR-based rubber compounds by analyzing small amounts of the species.

In March 2011, the model of cost accounting for Spanish public universities was approved and published based on the CANOA project of the Ministry of Education, Culture and Sport (MECD 2011). This paper focuses on rule 23 contained in chapter 8 of this document, where which regulates the treatment of the teaching and research dedication of university staff (PDI) and the allocation of corresponding cost to teaching, research and management. A reflection is made on certain points where there is the possibility of making different interpretations or in which satisfactory results are not obtained, with the consequences that this entails in the quality of the information and in the comparisons between universities. Finally, we present the preliminary results that the Universitat de València (UV) has obtained in its first pilot test around this rule. It is observed that 70% of the population analysed belong to the categories of teachers that according to rule 23 carry out research activity, and therefore the cost linked to them will not be fully passed on to the teaching activity. Of the total number of lecturers to whom rule 23 has not recognized any research activity, 83% belong to the body of a sort of lecturers, which is currently a minority and is on the way to extinction.

The study examines brand awareness, recall and bonding between the brand and the sponsored event, event involvement, value and the reputation of the institutional brand, as well as the perception among local attendees, using the Trinidad Alfonso Marathon celebrated in Valencia (Spain). A sample of 507 attendees (runners and viewers) was obtained and the results showed the relevance of the transfer of the perceptions of the sponsored activity to the institutional brand. Also, it was found that the type of event participation, the gender and the exposure determine different responses. The findings reveal a series of implications for brand managers in the public administration domain regarding the design of effective communication strategies aiming at building the desired positioning to one of the most relevant stakeholder groups: the residents in the territory which the institutional brand represents. Existing literature on sponsorship of participant sport-based events has generally focused on private brands and only with the perception of participants; the present research provides value by analysing perceptions from the heterogeneity of the public and in a public sphere.

The production of fruits and vegetables is listed as one of the most relevant activities in brazilian agricultural conjuncture. However, the amount of losses occurring along the production chain is alarming, especially in the postharvest stage. Thus, it was aimed to conduct a survey of postharvest losses and characterize the scenario of commercialization of fresh produce in the retail market of seven cities in the east of Maranhão state. This work was carried out through direct interviews with 145 traders. The questionnaire with objective questions that covered socioeconomic aspects, handling, flow, conditioning, storage, marketing, and postharvest losses was applied to them. It was found that the traders had little schooling (92% of traders do not have a high school level) and lack adequate technical knowledge of produce, management, and marketing of fruit and vegetable produce. The traded vegetables are sourced from Piauí, Bahia and Ceará, and drained through canvas-covered trucks (86%). The three vegetables with the highest loss estimates are bell pepper (16.42 ± 2.21%), lettuce (11.79 ± 0.42) and tomato (11.38 ± 0.19%). Though, for fruits, it highlights plum (35.65 ± 1.34%), papaya (17.93 ± 3.79%) and guava (15.63±2.79%). Among the causes, those of physiological order was the most impacting. The largest losses of vegetables occurred in Coelho Neto (17.78%), Timon (13.46%) and Brejo (10.73%) cities. Regarding fruits, the order was Coelho Neto (11.48%), Brejo (11.27%) and Timon (10.84%). There is a need for better training and awareness of traders regarding the adoption of good post-harvest practices and proper management of the commercial activity, as a way to increase the profitability of this activity, which on average is equivalent to two minimum wages per month.
Death and the Search for Heideggerian Authenticity inNo Country for Old Men
Authors: Phipps Gregory
Published: March 2020

This article explores intersections between Martin Heidegger's existentialist theories of death and authenticity and Cormac McCarthy's No Country for Old Men. Scholars have located existentialist strains in McCarthy's literature, but this article offers a new reading of Anton Chigurh's role as an embodiment of both death and the search for authentic existence. Working against the critical consensus that Chigurh's dialogues with his victims are grounded on a desire to provoke them to a deeper understanding of their situations, I argue that Chigurh is actually trying to bring about an existentialist understanding of death for himself. In Heidegger's Being and Time, such an understanding involves breaking free of societal views that treat death as a threat consigned to a distant future and embracing mortality as a possibility that is at once certain, indefinite, and intrinsic to one's existence.
Comparing welfare indicators in dairy cattle under different loose housing systems (deep litter vs cubicle barns) using recycled manure solids for bedding
Authors: Molina Laura , Agüera Estrella I. , Pérez-Marín Carlos C. , Maroto-Molina Francisco
Published: March 2020

Aim of study: Dairy farmers in Southern Spain are continuously investing in the modernization of their facilities and frequently ask technicians about the type of housing they should choose for their farms. Although some studies have analysed the economic impact of different housing systems, there are no reports evaluating the impact of these systems on animal wellbeing. To remedy this deficit, a study was carried out to analyse animal welfare status in two types of loose housing conditions: deep litter (DL) and cubicle (CU) barns.Area of study: This study was conducted in Cordoba (Spain).Material and methods: A total of 1,597 cows from nineteen commercial dairy farms were involved in this study, of which twelve had CU barns and seven had DL barns. Welfare Quality assessment was used to evaluate animal wellbeing, inn order to compare both housing systems.Main results: The study found some weaknesses for feeding and health indicators of animal welfare in both types of housing systems. The overall welfare assessment based on feeding, housing and health indicators showed no differences between farms with DL or CU barns.Research highlights: A good welfare status could be reached under any type of housing system.
Determinants of Audit Sanctions Severity
Authors: Azzali Stefano , Mazza Tatiana
Published: March 2020

This study investigates the effects of material weaknesses from auditing standards and of material misstatement from accounting standards on the audit sanctions severity. Using a unique database in the period 1983 – 2015, we find mixed results. Among the auditing standards, Internal Control Weaknesses lead to more severe audit sanctions than Quality Control, Other Auditors, Reporting and Audit Opinion Material Weaknesses Audit Sanctions, and to less severe audit sanctions than Professional Skepticism and Substantial Procedures. Among accounting standards, Fair Value misstatements are associated with more severe audit sanctions than Long-term investment, bank debts, and liquidity errors, and with lower severity of audit sanctions than Account receivables. Taken together, these findings suggest two main determinants of audit sanctions severity that auditors and accountants need to be aware: the area of internal control deficiencies and the area of fair value measurement. From these results, we learn that accounting and auditing standards errors have different likelihood of audit sanctions, and that auditors that aim to avoid sanctions need to invest mainly in the internal control assurance and in the fair value items of the financial reporting.
The Personality Factor of Conscientiousness on Skills Requirement and Fraud Risk Assessment Performance
Authors: Mansour Ala'a Zuhair , Ahmi Aidi , Popoola Oluwatoyin Muse Johnson
Published: March 2020

The study examines the moderation effect of the personality factor of conscientiousness on the relationship between skills (forensic accountant and auditor) and fraud risk assessment task performance in the Jordanian public sector. The forensic accountant skills denote enhanced level of capability purposely required to collect evidence in respect of fraud prevention, detection, deterrence as well as response. Whereas, the auditing standards require auditors to make available realistic guarantees in terms of sufficiency and reliability that the financial statements as a whole are free from material misstatements arising from fraud or error. Despite efforts by the government in reducing cases of fraud through a measure of reforms such as the establishment and strengthening of accountability organs and promoting global best practices for corporate organisations, fraud and financial crimes in the public sector of Jordan are still increasing. Hence, this paper develops a conceptual framework to investigate the moderating effect of conscientiousness on skills requirements and fraud risk assessment performance. The study will assist the forensic accountants and auditors working as regulators in the public sector environment concerning fraud prevention, detection, and response. It also creates awareness among accounting information users in the public sector. The paper contributes to the literature on personality factors of conscientiousness, auditing and forensic accounting, enhanced capability skills requirement, and competence (fraud risk assessment performance) by forensic accountants and auditors about fraud prevention, detection, and response in the Jordanian public sector.

Published: March 2020

This research aimed to investigate the applicability of forensic accounting to reduce fraud and its effects on financial statement of Jordanian Shareholding Companies from the perspective of Judiciary and Certified Public Accountant. This study used the descriptive analytical method. In order to elicit data from the participants, the researcher used a questionnaire survey distributed over a randomly selected sample from competent authorities in the financial criminal cases in the Jordanian Courts (Judges, Public Prosecutors), Certified Public Accountants licensed to practice auditing, and chartered accountants with expertise in financial cases in the Jordanian courts, to investigate their perceptions and views about the applicability of Forensic Accounting to reducefraud and its effects on financial statement of Jordanian Shareholding Companies. The researcher used the statistical analysis program (SPSS) to analyze the collected data in addition of the regression equation test, the statistical differences test for the non-scientific samples.The findings of the study showed that there is a necessity for providing the requirements, components, procedures and activities of Forensic Accounting in Jordan to reduce fraud and its effects on financial statement of Jordanian Shareholding Companies from the perspective of Judiciary and Certified Public Accountant. Also, the results of the study indicated that there is a difference between the judicial authority and Certified Public Accountants perceptions. Based on these findings, the study lists a set of recommendations the most important of which is adopt the requirements and principles of applying Forensic Accounting by decision-makers and professional organizations, and to establish an official and independent professional association of Forensic Accountants to develop forensic accounting standards and legislation, and to raise the awareness of the judicial authorities concerning the importance of the concept of Forensic Accounting in resolving financial criminal cases, and the extent of its contribution in rationalizing judicial decisions.
Responding to disruptive behaviors in nursing: One-year follow-up of quasi-experimental research measuring links to turnover, intent to leave, and patient care quality
Authors: Sanner-Stiehr Ericka
Published: March 2020

Background and objectives: Disruptive behaviors among nurses are a prevalent problem in health care, contributing to nursing staff turnover and compromising patient care. Newly licensed nurses may be unprepared to respond to disruptive behaviors effectively, negatively impacting them, patients, and organizations. Cognitive rehearsal can increase self-efficacy to respond effectively to disruptive behaviors. The purpose of this study was to determine the longitudinal impact of a cognitive rehearsal intervention delivered to nursing students during the final semester of their pre-licensure program on self-efficacy to respond to disruptive behaviors, turnover and intent to stay in a job, frequency of disruptive behaviors, and perceived impact on patient care.Methods: Design: This study was the second phase in a quasi-experimental, longitudinal project. Participants and Setting: In Phase 1, 129 participants were recruited from three pre-licensure nursing programs in the Midwestern United States. All participants received the intervention. In Phase 2, one year after graduating, 95 remained enrolled. Methods: An electronic survey was used to collect data. Paired t-tests were used to detect changes in self-efficacy; bi-variate correlations were utilized to determine relationships between outcome variables.Results: Multiple measures of self-efficacy to respond remained statistically significantly increased one year after graduating (p < .05). Experiencing (r = .489; p < .000) and witnessing (r = .432; p < .000) disruptive behaviors was significantly linked to patient care.Conclusions: Cognitive rehearsal had a sustained, positive impact on self-efficacy to respond to disruptive behaviors and should be included in pre-licensure curricula.

Published: March 2020

Introduction: The paper aims to demonstrate the Clinic’s and own research in the treatment of major salivary gland tumors.
Material and method: In the years 2013–2019, there were 95 salivary gland surgeries, including 45 performed in women (47.36%) aged between 24 and 82 and in 50 men (52.64%) aged 29 to 86. Diagnostics of major salivary glands included: patient history, otolaryngological examination, ultrasound and fine needle aspiration (BACC) (of tumor), laboratory tests (morphology, CRP) and computed tomography (CT) or magnetic resonance imaging (MRI) to accurately assess salivary glands, location of lesion and lymph nodes prior to elective surgery.
Research results: In the analyzed material patients with major salivary gland tumors were most frequently operated on at the age of 61–70 (34.7%) and 51–60 years (23.2%). Most patients with tumors were hospitalized in the last 4 years between 2016–2019, which accounted for 77.8% of all operated cases. Among the operated lesions, benign neoplasms and tumors occurred in 93.7%, of which the most frequent findings in histopathological examination were Warthin tumor in 50.5%, and multiform adenoma in 26.3%. The remaining tumors and benign neoplasms constituted only 16.9% and were observed in isolated cases, including eosinophilic adenoma, lymphoepithelial cyst, myoepithelial adenoma, lipofibrosarcoma, congestive cyst, air cyst, tubular adenoma, basal cell carcinoma, cyst with squamous metaplasia features, vascular malformation. Malignant salivary gland tumors were found in 6.3%, including the following malignant tumors were revealed histopathologically: adenocarcinoma, mucoepidermal carcinoma, acinocellular carcinoma, epithelialmyoepithelial carcinoma, ductal carcinoma.
Conclusions: The majority of operated salivary gland tumors were benign (93.7%), of which the most common histopathologically were: Warthin tumor (50.5%) and multiform adenoma (26.3%), while malignant tumors occurred in 6.3%. Tumors were localized mainly in the parotid gland in as many as 93.7% cases, of which the most common localization concerned the superficial lobe in 56.8%. The most frequent surgical technique used in the Clinic was extracapsular dissection of the tumor in 88.4%, and other methods were used rarely.
Persistence of Non-Vertigo Symptoms in Meniere Disease During Remission – A Preliminary Report
Authors: Olusesi Abiodun , Oyeniran Olubukola
Published: March 2020

Background: Though the absence of vertigo in Meniere disease is often interpreted as remission, patient-centered subjective assessment of quality of life remains the best indicator of such remission. Study Objective: To assess the presence and severity of aural pressure/tinnitus, hearing loss, unsteadiness, nausea and vomiting in MD patients during remission. Setting: Urban tertiary care referral hospital in a developing country. Methodology: Consecutive patients with diagnosis of Definite Meniere were selected from the Balance and Dizziness Clinic of National Hospital Abuja for the study. Quality of life assessment was carried out using 3 validated tools – Modified MD-POSI, Vertigo Symptom Scale and Tinnitus Handicap Inventory (THI). Patients were included only when they have been vertigo free for at least 4 weeks. Pure tone audiometry was carried out in those with subjective hearing loss at recruitment and 4 weeks later. Results: A total of 26 patients completed the study. All had cinnarizine for acute vertigo control and Betahistine for maintenance of vertigo control. There was female preponderance (17:9). The age range was 32–56 years. The duration of MD ranges from 4 months to 12 years. The total and subscale MD-POSI scores for “between attacks” significantly correlated with hearing, unsteadiness and tinnitus/pressure when compared to during attack. 69.2 per cent of participants experienced symptoms of unsteadiness during remission. 13/26 of participants reported persistent, though less annoying tinnitus that poorly correlated with THI score during remission. Conclusion: Our study showed that significant non-vertigo symptoms affect the quality of life during remission. Perhaps there is need to properly define, in future studies, what constitutes remission in patients with MD.
Monitoring and modeling of heavy metal contents in vegetables collected from markets in Imo State, Nigeria
Authors: Isiuku Beniah Obinna , Enyoh Christian Ebere
Published: March 2020

Vegetable consumption is one major exposure route of heavy metals to humans, but few data exist for Imo State, Nigeria. We assessed the contamination levels and associated health risk of cadmium (Cd), cobalt (Co), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) in vegetables (Telfairia occidentalis, Pterocarpus mildbraedii, Gongronenina latifolium and Vernonia amygdalina) that are consumed frequently from markets (n=16) in three zones of Imo State, Nigeria. After wet-digestion of samples, the supernatant were analyzed using atomic absorption spectrophotometry. The mean concentrations in the four vegetables ranged from 0.006±0.003 mg/kg to 0.011±0.007 mg/kg for Cd, 0.064±0.012 mg/kg to 1.225±0.226 mg/kg for Co, 10.711±1.968 mg/kg to 25.088±13.975 mg/kg for Cu, 0.062±0.013 mg/kg to 0.307±0.210 mg/kg for Ni, 0.006±0.005 mg/kg to 0.012±0.002 mg/kg for Pb and 63.55±4.055 mg/kg to 104.126±24.080 mg/kg for Zn. Except for Zn, all heavy metals in the various vegetables were below the joint standard of Food and Agriculture Organization and World Health Organization. Although, overall load of heavy metal was very low, Zn had the highest contamination factor in vegetables. Heavy metals concentrations in vegetables generally showed low to high variations and statistically different (p<0.05). Average daily intake was below the provisional tolerance limit except for Zn. The target hazard quotient of metals in vegetables for both children and adults were below 1, indicating no potential risk to the public. Overall, heavy metals hazard index were below 1, indicating acceptable level of non-carcinogenic adverse health effect. However, potential multi-element contamination from ingestion is possible as revealed by the correlation profiling of heavy metals.
Mismatch Removal Based on Gaussian Mixture Model for Aircraft Surface Texture Mapping
Authors: Niu Guochen , Wang Licheng , Tan Zheng
Published: March 2020

Aiming at the fact of lower efficiency and higher time cost for feature matching in aircraft surface texture mapping process, a novel mismatch removal method based on Gaussian mixture model is proposed to increase correct corresponding feature matching point pairs. The detection and initial point sets for corresponding pairs are carried out, and a vector field is interpolated between the two matching of ORB feature points. The Gaussian mixture model(GMM) is introduced and a prior is taken to force the smoothness of the field, which is based on the Tikhonov regularization in vector-valued reproducing kernel Hilbert space(RKHS). In order to obtain the optimal estimation, the MAP solution of a Bayesian model with latent variables, which could be performed by Expectation Maximization (EM) algorithm, is utilized to determine the correct correspondence. The experimental results show that the algorithm could remove mismatches effectively and the classification for feature points is excellent. The calculation time is greatly reduced, which enhanced real-time performance of aircraft surface texture mapping process.

Authors: Coban Sezer
Published: March 2020

In this study, it is examined that simultaneous flight control system and lateral and longitudional state-space model of a Unmanned Aerial Vehicle (UAV) and real time application. For this purpose an UAV whose wing and tail unit can be assembled to fuselage from different points in a prescribed interval and whose wing and tail can move forward and backward independently in tail to nose direction is manufactured. Following this, an autopilot is purchased and it lets change of P, I, D coefficients in certain intervals. First, dynamic model, and longitudinal and lateral state space models of UAV are obtained and then simulation model of UAV is reached. At the same time block diagram of autopilot system and modeling of it in MATLAB/Simulink environment are found. After these, using these two models and also benefiting and adaptive stochastic optimization method namely SPSA, simultaneous design of UAV and autopilot is done in order to minimize a cost function consisting of rise time, settling time and maximum overshoot. Therefore, primarily autonomous performance is maximized in computer environment. Moreover, high performance is observed by looking at simulation responses and real-time flights.

A hand contour is used, topological description of the hand, evolutionary algorithm, algorithm linear regression to estimate the knuckles positions and for contours comparison is used an algorithm Iterative Closest Point (ICP) in its genuine shape. All 5 fingers is at computer classification fully moveable, thumb has 2 knuckles. Modern evolutionary optimizers enable markedly to cut down computational demands of the algorithm ICP. Experimental verification of proposed recipes were performed with use of two different databases named THID and GPDS with persons of both gender and different age (cca 20-65let) with total number of oeprons in individual database 104 and 94. Experimental results checked succesfuly suitability of use combination of methods ICP and evolutionary optimizer which is named as EPSDE for solving of the given task with algorithmic complexity O(N) and success rate give by coefficient THID:EER=0.38% and GPDS:EER=0.35% on real images.

Traditionally torrential rains are considered to be the main factor of flood emergence. But with some examples of disastrous floods in absolutely different parts of the world, the rough estimation of the water balance results in the necessity to suggest a correct alternative hypothesis. Our simplest model (taking into account precipitation, evaporation, and soil permeability) clearly points out the significant discrepancy in several events between potentially accumulated and observed water masses. This observation puts forward the idea that precipitation is necessary, but it is not often a sufficient factor for disastrous flood emergence and for the water flow budget. Thus, another available water source, i.e., groundwater, should not be ignored. We consider the reasons and conditions for such phenomena. In this chapter, we will focus only on the causes and forecast of dangerous dynamic phenomena in rock masses. Of particular interest here are water flows through various granite massifs and geological rocks of magmatic origin using nonlinear dynamics approaches.
A Brief Overview of CRC Implementation for 5G NR
Authors: Wu Hao
Published: March 2020

In fifth generation (5G) new radio (NR), the medium access control (MAC) layer organizes the data into the transport block and transmits it to the physical layer. The transport block consists of up to million bits. When the transport block size exceeds a threshold, the transport block is divided into multiple equal size code blocks. The code block consists of up to 8448 bits. Both the transport block and the code block have a cyclic redundancy check (CRC) attached. Due to the difference in the size of the transport block and the code block, the CRC processing scheme suitable for the transport block and that suitable for the code block are different. This chapter gives an overview of the CRC implementation in 5G NR.
Constitution and Dependence
Authors: Kovacs David Mark ,   Journal of Philosophy Inc.
Published: March 2020

Constitution is the relation that holds between an object and what it is made of: statues are constituted by the lumps of matter they coincide with; flags, one may think, are constituted by colored pieces of cloth; and perhaps human persons are constituted by biological organisms. Constitution is often thought to be a "dependence relation." In this paper, I argue that given some plausible theses about ontological dependence, most definitions of constitution don’t allow us to retain this popular doctrine. The best option for those who want to maintain that constitution is a dependence relation is to endorse a kind of mereological hylomorphism: constituted objects have their constituters as proper parts, along with a form, which is another proper part. The upshot is that constitution theorists who think of constitution as a dependence relation but are reluctant to endorse mereological hylomorphism ought to give up one of their commitments.
The Causal Decision Theorist's Guide to Managing the News
Authors: Gallow J. Dmitri ,   Journal of Philosophy Inc.
Published: March 2020

According to orthodox causal decision theory, performing an action can give you information about factors outside of your control, but you should not take this information into account when deciding what to do. Causal decision theorists caution against an irrational policy of "managing the news." But, by providing information about factors outside of your control, performing an act can give you two, importantly different, kinds of news. It can tell you that the world in which you find yourself is good, and it can tell you that the act itself is in a position to make the world better. While the first kind of news does not speak in favor of performing an act, I believe that the second kind of news does. I present a revision of causal decision theory which advises you to manage the news about the good you stand to promote, while ignoring news about the good the world has provided for you.
Some Approaches to an Ethics for Disaster
Authors: Souffrant Eddy ,   The Society for Philosophy in the Contemporary World
Published: March 2020

We have witnessed, and in some instance from afar, disasters of all sorts that span the globe from the Caribbean, South and North America, Asia, to Australia and other affected regions of the world. Some of these destabilizing and at times fatal events have resulted in lives lost, forced migration, and a restructuring of the physical, social and economic architecture of the affected parts of the globe. Further, the disasters as massive restructuring of the physical and psychological status quo are at times human made and at others, natural.

“… I denne Tid maa man ogsaa kunde taale at se Blod”. Frits Clausen i russisk krigsfangenskab 1915-18
Authors: Lauridsen John T.
Published: March 2020

Frits Clausen, the future leader of the Nationalist Socialist Workers Party of Denmark (DNSAP), was a Russian prison of war from 1915-18. The development that he underwent in captivity is examined through contemporary letters and later articles and reminiscences. He was forced to enlist in the German army as a professed Danish nationalist, and for him the war represented a possibility and a hope that Germany would lose, providing an opportunity for North Schleswig to be reunited with Denmark. He put this goal higher than other considerations, including the German orientation of Schleswigers, and his dislike of the Danish Social-Liberal Party was due in an inordinate degree to press releases from Denmark reporting the party’s half-hearted attitude to the North Schleswig issue. He also clashed with the Danish clergyman who was sent to minister to the prisoners of war from North Schleswig. The clergyman was more of an upright, neutral Danish official than a wholehearted advocate of the North Schleswig case. In this respect the clergyman was a disappointment in Frits Clausen’s eyes. His recommendation that the pro-Danish prisoners of war from North Schleswig should return to Germany to resuming fighting on the German side following the separate peace treaty between Germany and Russia was more than Frits Clausen could cope with. He went over the clergyman’s head and tried, together with a small number of like-minded individuals, to fight against Germany, but his attempt failed. In the course of his endeavours he developed a hatred of the new Soviet regime, as personified by the Marxist Jew, but in other respects had gained an excellent impression of the Russians, who he in no way considered to be an inferior people. On his return from Russia he expressed his anti-Semitism and anti-Communism in various anonymous articles in the press. This was the first step towards keeping the promise, made to himself during his captivity, to dedicate his life to the struggle against Marxism.
Fem nyfundne Niels Stensen-breve
Authors: Bruun Niels W.
Published: March 2020

In dem Artikel werden erstmalig fünf in Latein abgefaßte Niels Stensen-Briefe, die kürzlich in der Gottfried Wilhelm Leibniz Bibliothek – Niedersächsische Landesbibliothek in Hannover aufgefunden wurden, nebst einer dänischen Übersetzung herausgegeben. Die aus den Jahren 1669, 1670 bzw. 1673 stammenden Briefe bezeugen, daß Niels Stensen mit Heinrich Meibom dem Jüngeren (1638-1700), Professor der Medizin in Helmstedt, und mit dem herzoglich-gottorfischen Leibarzt Joel Langelott (1617-1680) korrespondiert hat. Letztere waren der Stensen-Forschung als Briefadressaten bislang unbekannt. Jedem Brief ist ein Kommentar beigefügt, der sowohl über Realien Auskunft erteilt als auch den Inhalt des Briefes und dessen Kontext im Werk Stensens erörtert. Ein Brief von Joel Langelott an Heinrich Meibom den Jüngeren wird im Anhang mitgeteilt.

Fuglene. Audubons "Birds of America"
Authors: Schlichtkrull Torsten
Published: March 2020

NB: Artiklen er på dansk, kun resuméet er på engelsk. The Royal Library owns one of the most exceptional works in book history, an original edition of John James Audubon Birds of America. This edition, in a format called “double elephant folio” was published from 1827 to 1838. On basis of existing literature, this article briefly describes the work’s genesis, including Audubon’s technique, printing, the letterpress, conservation history as well as the pricing of the book when it was published. The work was originally acquired for The Classen’s Library (Det Classenske Bibliotek), a private research library, which, although considerably smaller than the Royal Library and the University Library, joined the library cooperation of the 1800’s on an equal standing with the other two libraries. The Classen’s Library and the library’s founder, industrialist JF Classen are described briefly in this article. Due to two library mergers the Birds of America is now owned by the Royal Library. The acquisition of the Danish set by the Classen’s Library is examined by analyzing previously unpublished letters and is described for the first time, although not comprehensively, in this article. The provenance of this work, as described by Waldemar Fries in 1973, is reexamined in this article. Using newly discovered archival material and a review of available literature, this article concludes that the Danish set was assembled in 1857/58 from loose sheets, and was most likely created simultaneously with three other sets, two of which are believed to be the Mill Grove, Pennsylvania, USA and Library of Parliament, Ottawa, Canada sets.
