Incomplete Iterative Implicit Schemes
Authors: Vabishchevich Petr N.
Published: March 2019

In numerical solving boundary value problems for parabolic equations, two- or three-level implicit schemes are in common use. Their computational implementation is based on solving a discrete elliptic problem at a new time level. For this purpose, various iterative methods are applied to multidimensional problems evaluating an approximate solution with some error. It is necessary to ensure that these errors do not violate the stability of the approximate solution, i.e., the approximate solution must converge to the exact one. In the present paper, these questions are investigated in numerical solving a Cauchy problem for a linear evolutionary equation of first order, which is considered in a finite-dimensional Hilbert space. The study is based on the general theory of stability (well-posedness) of operator-difference schemes developed by Samarskii. The iterative methods used in the study are considered from the same general positions.

Background

Cystathionine γ-lyase enzyme, which is encoded by theCTHgene, is responsible for hydrogen sulfide (H2S) production in the endothelium. TheCTH1364 G>T polymorphism may alter theCTHexpression and H2S bioavailability, thus leading to atherosclerosis and coronary artery disease (CAD). We examined the potential association of theCTH1364 G>T polymorphism with CAD.

Methods

TheCTH1364 G>T polymorphism was determined in 178 coronary artery bypass grafting (CABG) patients and 156 non-atherosclerotic controls of Greek Caucasian origin using the PCR–RFLP method.

Results

No significant difference in the frequency of theCTH1364 G>T genotypes (p = 0.281) and alleles (p = 0.265) was found between the CABG patients and controls. After conducting stratification according to sex, analysis showed a numerical difference in theCTH1364 TT genotype frequency in female participants that did not reach statistical significance (16.3% and 8.5% in the CABG and controls, respectively, p = 0.26). The frequency of theCTH1364 TT genotype between the male CABG patients and controls did not differ (p = 0.507).

Conclusions

TheCTH1364 G>T polymorphism was not associated with CAD in the studied population. However, interestingly, a higher – if not significantly so –CTH1364 TT genotype frequency was present in female CABG patients compared with female controls. Larger studies are necessary to conclude on the potential overall or gender-driven association betweenCTH1364 G>T gene polymorphism and CAD.

Published: March 2019

Structural and functional changes in ultrasonicated oyster protein isolates (OPI) were investigated. Ultrasound treatments were carried out with probe (20 kHz) at 200, 400 and 600 W for 15 and 30 min. The results showed that functional properties of OPI significantly improved after sonication. Absolute zeta potential and protein solubility increased by 18.40 mV and 82.5 % at 600 W for 15 min. Oil holding capacity, emulsifying activity index, emulsion stability index, foaming ability and foaming stability increased by 300 %, 15.23 m2/g, 9.24 min, 23.9 % and 14.8 % at 600 W for 30 min. However, ultrasound treatment significantly (P < 0.05) decreased particle size and water holding capacity. The conformation of OPI became stretched and unfolded after sonication. Functional improvements resulted from stretched and unfolded conformation and reduction of particle size. Controlled condition of ultrasound can produce OPI with distinct structural and functional properties, which could meet the complex needs of manufactured food products in food industry, but further study is needed to understand the specific mechanism.

Published: March 2019

The process of sugar evaporative crystallization is a nonlinear process with large time lag and strong coupling. It is difficult to establish a reasonable mechanism model. In this paper, we use the data driving modeling method to establish an Adaptive Control model for batch boiling sugar crystallization process. First, by analyzing the main influencing factors of the evaporative crystallization process of intermittent boiling sugar, the most important two parameters, brix and liquid level, are selected as the control object. The self-adaptive differential evolution Extreme Learning Machine (SaDE-ELM) is used to construct the control model. A least squares support vector machine (LSSVM) is established and connected in the control loop to control the opening of the feed valve so that to control the feed flowrate according to the objective values of syrup Brix and liquid level. Experiments are conducted and the obtained data are used to train and verify the learning machines. Experiments indicate that the learning machines are able to realize adaptive control to key parameters of the crystallization process. Comparison of different neural networks indicates that the LSSVM performs better than BP, RBF and ELM and SaDE-ELM with prediction error of below 0.01, and training time of below 0.05 s.

Published: March 2019

Kedondong (Spondias dulcis) contains polyphenols, vitamin C and carotenoids which are beneficial to human health. Fresh kedondong has short shelf life and drying is an option to preserve the fruit in dried form to avoid spoilage. In this research, kedondong slices were dried at three temperatures (60 °C, 70 °C and 80 °C) using convective air and RH was fixed at 30 %. High drying temperature facilitated faster drying rate but resulted in poor product quality when compared to freeze dried samples. Drying rates were observed only occurred within falling rates period. Effective diffusivities were estimated in the order of magnitude 10–7 - 10–9 m2/s based on Fick’s second law. Quality assessment showed that samples dried at 60 °C had the lowest hardness and the highest total polyphenols content was observed from samples dried at 80 °C. In addition, kedondong flavour note was found favourable from samples dried at 70 °C and 80 °C based on penalty analyses.

“Animal spirits” and bank’s lending behaviour, a disequilibrium approach
Authors: Chiarella Carl , Di Guilmi Corrado , Zhi Tianhao
Published: March 2019

The paper analyses from a disequilibrium perspective the role of banks’ “animal spirits” and collective behaviour in the creation of credit that, ultimately, determines the credit cycle. In particular, we propose a dynamic model to analyse how the transmission of waves of optimism and pessimism in the supply side of the credit market interacts with the business cycle. We adopt the Weidlich-Haag-Lux approach to model the opinion contagion of bankers. We test different assumptions on banks’ behaviour and find that opinion contagion and herding amongst banks play an important role in propagating the credit cycle and destabilizing the real economy. The boom phases trigger banks’ optimism that collectively lead the banks to lend excessively, thus reinforcing the credit bubble. Eventually the bubbles collapse due to an over-accumulation of debt, leading to a restrictive phase in the credit cycle.
Diffraction of Electromagnetic Waves
Authors: Brosa Ulrich
Published: March 2019

The general method to obtain solutions of the Maxwellian equations from scalar representatives is developed and applied to the diffraction of electromagnetic waves. Kirchhoff’s integral is modified to provide explicit expressions for these representatives. The respective integrals are then evaluated using the method of stationary phase in two dimensions. Hitherto unknown formulae for the polarization appear as well as for imaging by diffraction. Ready-to-use formulae describing Fresnel diffraction behind a round stop are presented.

Published: March 2019

The present work investigates the performance of Ga-doped ZnO (GZO) and Ca-doped ZnO (CZ) nanopowders as an efficient nanomaterials for the removal of lead ions from aqueous solutions. The sol–gel method was used to synthesise the nanoparticles from zinc acetate dihydrate. To incorporate Ca and Ga in ZnO, adequate quantities of calcium chloride hexahydrate and gallium nitrate hydrate were added to ZnO, and supercritical drying conditions of ethyl alcohol were used. Different Ca and Ga concentrations (1, 2, 3, 4, 5 at.%) were used to synthesise CZ and GZO. The structural and morphological properties of the as-prepared nanoparticles were determined using X-ray diffraction and transmission electron microscopy. Batch-mode experiments were used to remove lead from aqueous solution and to determine the adsorption equilibrium isotherms of lead ions using ZnO doped by 3 at.% of weight of Ca (CZ3) and Ga (GZO3). The effects of temperature, contact time, and pH on the removal of lead ions from aqueous solution by CZ3 and GZO3 were studied.
Region- and Cell Type-Specific Facilitation of Synaptic Function at Destination Synapses Induced by Oligodendrocyte Depolarization

Published: March 2019

The axonal conduction of action potentials affects the absolute time it takes to transmit nerve impulses as well as temporal summation at destination synapses. At the physiological level, oligodendrocyte depolarization facilitates axonal conduction along myelinated fibers in the hippocampus; however, the functional significance of this facilitation is largely unknown. In this study, we examined the physiology of the facilitation of axonal conduction by investigating the changes in synaptic responses at destination synapses using male and female mice in which channelrhodopsin-2 expression was restricted to oligodendrocytes. The subiculum, one of the projection areas of the examined axons at the alveus of the hippocampus, is divided into three regions (proximal, mid, and distal) and contains two types of principal neurons: regular firing and bursting pyramidal cells. We found a significant increase in excitatory synaptic responses following optogenetic oligodendrocyte depolarization in bursting neurons at two of the three regions, but not in regular firing neurons at any region. The long-term potentiation (LTP) induced by theta burst stimulation at the synapses showing a significant increase was also enhanced after oligodendrocyte depolarization. Conversely, the reduction of oligodendrocyte depolarization during theta burst stimulation, which was achieved by photostimulation of archaerhodopsin-T expressed selectively on oligodendrocytes, reduced the magnitude of LTP. These results show that oligodendrocyte depolarization contributes to the fine control of synaptic activity between the axons they myelinate and targets subicular cells in a region- and cell type-specific manner, and suggest that oligodendrocyte depolarization during conditioning of stimuli is involved in the induction of LTP.

SIGNIFICANCE STATEMENTAll activity in the nervous system depends on the propagation of action potentials. Changes in the axonal conduction of action potentials influence the timing of synaptic transmission and information processing in neural circuits. At the physiological level, oligodendrocyte depolarization facilitates axonal conduction along myelinated fibers. In this study, we investigated the functional significance of the facilitation of axonal conduction induced by physiological oligodendrocyte depolarization. Using optogenetics and electrophysiological recordings, we demonstrated that oligodendrocyte depolarization in mice expressing channelrhodopsin-2 on oligodendrocytes increased excitatory synaptic responses and enhanced the induction of long-term potentiation at destination synapses in a region- and cell type-specific manner. This facilitation may have a hitherto unappreciated influence on the transfer of information between regions in the nervous system.
Legalism in the Kitchen: Relativizing the Ethics and Performance of Gastronomic Expertise
Authors: Herzfeld Michael
Published: March 2019

By adopting a “weak” version of cultural relativism, we can manage our own ethical discomfort without disrespecting those whose culinary values and practices we do not share. This entails recognizing the contextual and performative aspects of all gastronomic rhetoric, including claims of expertise over questions of culinary authenticity and standards of acceptable behavior during the consumption of food and drink; all such claims, while often couched in the language of moral certainty, are in reality susceptible to contestation. It is thus in the language of right and wrong that those engaged in culinary discussions affirm, negotiate, and modify the prevailing standards of taste and good manners. This becomes especially clear when local people test foreigners' willingness to adapt to local gastronomic practices and styles of consumption, aspects of performance that are often coded in ways that force uninitiated outsiders to fail, perhaps unknowingly, in local eyes.
Old Sake in New Glasses: Reframing Japan's National Drink through Global Wine Culture
Authors: Wang Chuanfei
Published: March 2019

Japan is experiencing a sake boom, more precisely, the growing popularity of premium sake. It is the result of a dramatic reform of the Japanese sake industry over the past few decades. In this article, I argue that, from a cultural perspective, wine culture is being adopted as a cultural frame to facilitate the revival and rebranding of Japan's national drink. This adoption is a “culinary translation” of Japanese sake through the globally familiar language of wine. In this process, the Japaneseness of sake is by no means challenged, but made “legible” through the more familiar discourse and practices prevalent in the culture of wine.
Đổi Mới and the Globalization of Vietnamese Art
Authors: Taylor Nora A. , Corey Pamela N.
Published: March 2019

Đổi Mới reforms triggered significant changes in the Vietnamese art world, including new institutional spaces, platforms for critical discourse, and growing artistic mobility. However, it is important to question the ways in which the use of Đổi Mới as a blanket indicator of artistic reform has further constructed a homogeneous representation of “Vietnamese contemporary art.” The authors consider the relationship of Đổi Mới to the “globalization” of Vietnamese art with attention to questions of art historiography (the coining of such terms as “post-Đổi Mới Vietnamese art”) and variations in regional developments (positing local art histories against the national narrative).

Two key features of recombinant inbred panels are well-characterized genomes and reproducibility. Here we report on the sequenced genomes of six additional Collaborative Cross (CC) strains and on inbreeding progress of 72 CC strains. We have previously reported on the sequences of 69 CC strains that were publicly available, bringing the total of CC strains with whole genome sequence up to 75. The sequencing of these six CC strains updates the efforts toward inbreeding undertaken by the UNC Systems Genetics Core. The timing reflects our competing mandates to release to the public as many CC strains as possible while achieving an acceptable level of inbreeding. The new six strains have a higher than average founder contribution from non-domesticus strains than the previously released CC strains. Five of the six strains also have high residual heterozygosity (>14%), which may be related to non-domesticus founder contributions. Finally, we report on updated estimates on residual heterozygosity across the entire CC population using a novel, simple and cost effective genotyping platform on three mice from each strain. We observe a reduction in residual heterozygosity across all previously released CC strains. We discuss the optimal use of different genetic resources available for the CC population.
Cigarette Smoking Disparities Between Sexual Minority and Heterosexual Youth
Authors: Fish Jessica N. , Turner Blair , Phillips Gregory , Russell Stephen T.
Published: March 2019

BACKGROUND:

Using a population-based sample of youth, we examined rates of cigarette use and trends in cigarette use disparities between heterosexual youth and 3 subgroups of sexual minority youth (SMY) (ie, lesbian or gay, bisexual, and unsure) from 2005 to 2015.

METHODS:

Data are from 6 cohorts of the Youth Risk Behavior Survey, a national, biennial, school-based survey of ninth- to 12th-grade students in the United States (n = 404 583). Sex-stratified analyses conducted in 2017 examined trends in 2 cigarette-related behaviors: lifetime cigarette use and heavy cigarette use (20+ days in the past 30).

RESULTS:

Disparities in lifetime cigarette use between lesbian and heterosexual girls were statistically smaller in 2015 relative to 2005 (adjusted odds ratio [aOR] 0.29; 95% confidence interval [CI] 0.12–0.75; P = .011). Sexual orientation disparities in heavy use were narrower for bisexual boys in 2015 compared with 2005 (aOR 0.39; 95% CI 0.17–0.90; P = .028). Girls and boys unsure of their sexual identity had wider disparities in heavy use in 2015 (aOR 3.85; 95% CI 1.39–11.10; P = .009) relative to 2005 (aOR 2.44; 95% CI 1.22–5.00; P = .012).

CONCLUSIONS:

SMY remain at greater risk for cigarette-related behaviors despite greater acceptance of lesbian, gay, and bisexual people in the United States. Focused policies and programs aimed at reducing rates of SMY cigarette use are warranted, particularly for youth questioning their sexual identity.
Patrystyczny przedsiębiorca. Pojęcie działania przedsiębiorczego w świetle pism wybranych pisarzy wczesnochrześcijańskich
Authors: Niepsuj Łukasz
Published: March 2019

W bogactwie i różnorodności myśli patrystycznej znajdujemy wiele odniesień do życia gospodarczego i przedsiębiorczego. Problematyka ta, mimo że nie zyskała u autorów wczesnochrześcijańskich spójnej formy, w postaci traktatów ekonomicznych czy nawet teologicznych, to jednak nie była im obca.W swoich pismach autorzy ci prezentują szerokie odniesienie do problemów ekonomicznych i polityki gospodarczej współczesnego im społeczeństwa. Kreślą także pewną ideę działania przedsiębiorczego, typową dla kupców i ludzi bogatych. Dostrzegają płynące z tej aktywności zarówno niebezpieczeństwa, jak i korzyści.Podkreślają, że konieczne jest nie tyle zreformowanie owego ekonomicznego mechanizmu działania kupieckiego – przedsiębiorczego, który ze swej natury był im obcy, ile bardziej dostrzeżenie potrzeby przemiany moralnej i etycznej kupca, bogacza – przedsiębiorcy, który działa w strukturze owego mechanizmu. Chodzi zatem o pogodzenie ze sobą naturalnej tendencji jednostki do bogacenia się i pomnażania dóbr z troską o jej osobiste uświęcenie i o dobro wspólne. „Patrystyczny przedsiębiorca” ma być człowiekiem cnoty, który kieruje się zasadą wzajemności, solidarności i pomocniczości. Więcej, wydaje się, że dynamizm przedsiębiorczy nie może być obcy żadnemu wierzącemu. Każdy bowiem winien mieć coś z kupieckiego, przedsiębiorczego ducha, tj. posiąść tajemnicę inwestowania, ryzyka, zysku, aby pomnażając i rozdając hojnie swoje bogactwa materialne, wzrastać w bogactwie duchowym, w cnocie i w ten sposób przemieniać gospodarczą rzeczywistość rynku.

Mujeres jóvenes y el aborto en Chile: representaciones polarizadas
Authors: Jara Lissette , Rojas Camila , Martínez Soledad
Published: March 2019

El artículo presenta una aproximación exploratoria a la representación social sobre aborto en un grupo de mujeres jóvenes estudiantes universitarias en la ciudad de Chillán, Chile. Su importancia central radica en que la investigación se realiza justo en un marco temporo-espacial caracterizado por el debate nacional sobre la despenalización del aborto en tres causales, el que ha tenido lugar no solo en el ámbito legislativo, sino que a nivel de toda la sociedad chilena. El estudio fue cualitativo y utilizó cuestionarios abiertos y grupos focales. Los resultados muestran que el grupo con el cual se trabajó, representa el aborto de un modo altamente iconizado, con un componente emotivo importante, marcadamente negativo y centrado en aspectos individuales más que colectivos. Lo anterior coincide con los discursos conservadores y opositores a la despenalización del aborto en Chile.
Las indisciplinas sociales. Una excusa para no mirar allá
Authors: Riera Vásquez Celia M. , Fabré Machado Idalsis
Published: March 2019

En los últimos años se ha venido empleando en Cuba desde las instituciones representativas del control social formal, el término indisciplinas sociales para dar cuenta de comportamientos socialmente reprochables. El debate sobre esta problemática queda en los estrechos marcos del instrumentalismo y las posturas correctoras del comportamiento desviante. Los vacíos relativos a la normatividad social dan al traste con enfoques reactivo represores, que no parten del análisis del ordenamiento de la sociedad, de sus formas diferenciadas de organización; sino de una visión que redunda en la creación de estereotipos y la estigmatización de determinadas conductas y grupos. De ahí la necesidad de que las Ciencias Sociales aporten un marco conceptual para el análisis crítico del tema.

A Survey on Transfer Learning for Multiagent Reinforcement Learning Systems
Authors: Silva Felipe Leno Da , Costa Anna Helena Reali
Published: March 2019

Multiagent Reinforcement Learning (RL) solves complex tasks that require coordination with other agents through autonomous exploration of the environment. However, learning a complex task from scratch is impractical due to the huge sample complexity of RL algorithms. For this reason, reusing knowledge that can come from previous experience or other agents is indispensable to scale up multiagent RL algorithms. This survey provides a unifying view of the literature on knowledge reuse in multiagent RL. We define a taxonomy of solutions for the general knowledge reuse problem, providing a comprehensive discussion of recent progress on knowledge reuse in Multiagent Systems (MAS) and of techniques for knowledge reuse across agents (that may be actuating in a shared environment or not). We aim at encouraging the community to work towards reusing all the knowledge sources available in a MAS. For that, we provide an in-depth discussion of current lines of research and open questions.
An investigation of fracture properties and size effects of concrete using the ESPI technique
Authors: Chen Hongniao , Su Ray Kai Leung , Fok Alex Sui-Lun , Yuan Bo
Published: March 2019

In order to study the size effect in concrete fracture, three-point bending tests are performed on five groups of geometrically similar concrete beams. The electronic speckle pattern interferometry (ESPI) technique is used to measure the full-field deformation of concrete beams. Crack opening displacement data, which is crucial for understanding crack initiation and the evolution mechanism, but which is not readily available through conventional measurement techniques, is obtained. Fracture parameters of five groups of concrete beams, including the critical crack opening displacements (i.e. CMODc and CTODc) and crack growth lengths (i.e. ac and ae) at the peak, fracture toughness (KIc), fracture energy (GF) and nominal strength (σN), are determined. The influences of beam depth on the fracture parameters of concrete are evaluated and discussed. The results show that the CMODc, CTODc, ac, ae, KIc and GF increase with the increase in beam depth, while σN has a decreasing trend that follows the size effect law. Size-independent fracture toughness and fracture energy are estimated and proposed.

Nesse sentido, descrevemos e analisamos três projetos de leitura (Eu conto, tu recontas, nós nos encantamos, Cantinho do Era uma vez... e Sacola Viajante) aplicados nas turmas, considerando conceitos e pressupostos teóricos advindos da educação e da teoria literária. Os resultados obtidos nos levam a concluir que projetos de literatura em turmas de berçário propiciam a aproximação aos livros e contribuem para a formação de hábitos leitores, mas que a intenção pedagógica e o engajamento familiar são determinantes na sua concretização.

Military and Political Integration of the Scandinavian Countries in the European Security Architecture after the Second World War
Authors: Pavlenko Valerii
Published: March 2019

The Article examines the military and political integration of Scandinavia in the European security architecture after 1945 and analyzes the historical experience of the countries of the North Europe in the late 1940s-1960s in the security space issues. Particular attention is paid to the close link between the military and political rapprochement with the processes of the economic, technological and political integration in the Western European region. It is emphasized that the economic basis of common interests encourages the EU member states all the time to seek peaceful means to resolve possible disputes. Considerable attention is paid to the analysis of alternative approaches to the European security that the North European countries have used in their foreign policy. The role and place of these countries in the sphere of the European security during the late 1940s-1960s was determined. The influence of the USA and the USSR on the formation of the foreign policy of the Scandinavian countries, especially the pressure of the Soviet Union on Finland in its attempts to get a neutral state status, has been shown. The reasons for the failure to implement the military and political cooperation projects in the form of the Scandinavian Defense Alliance have been revealed.
Historic Context of European Union Leadership in Climate Change Mitigation
Authors: Shatokha Volodymyr
Published: March 2019

The role of European Union in defining of the international climate change mitigation policy was studied in the historic context of overcoming the differences in the approaches to reaching the sustainable development targets among the EU, the USA, China and some other influential countries. It has been shown that currently the processes of climate policy definition became more polycentric than in 1992, when the UN Framework Convention on Climate Change was signed. The ability to adjust to a new context, to build coalitions and to reach compromise with the wide range of international actors has been crucial for maintaining the EU’s influence on definition of the international climate change mitigation policy. Despite not always supportive internal and external factors, during a quarter of century the EU has managed to maintain its leadership and many times helped to enhance the ambition of global climatic targets by establishing the high level of own commitments and implementing relevant policy instruments. The EU and its members played a decisive role in ensuring of the non-interruptive international climate action during implementation of the Kyoto Protocol and in setting of the Paris Agreement which will define climate regime after 2020. Mitigation of climate change is a complicated task not only in terms of technology and socio-economic aspects but also with respect to policy implementation. Therefore the EU leadership in this sphere remains very important.

This study were
investigated the effect of SiC amount and milling time on microstructure,
density and hardness in the aluminum composites produced by mechanical milling.
In the study, aluminum composites were mechanical milling at different times
(30, 60, 90 and 120 min), adding SiC in different amounts (5%, 10%, 15% and
20%). A high chromium steel balls with a diameter of 6 mm, a ratio of 10:1
ball-powder and 2% stearic acid were used as milling component in the
production of composites in a vibrating mill. The production of composite
powders was carried out in an argon atmosphere. The composite powders produced
were characterized using scanning electron microscopy, EDS analysis, optical
microscope and powder size analyzer. As a result, it was observed that as the
amount of added SiC and milling time increased, the powder size decreased and
the hardness values increased. In addition, as the amount of added SiC
increased, the densities of aluminum composites increased.

Published: March 2019

Robots
are usually designed by inspiration from living creatures in the nature. It is
inspired by the behaviors of 4 legged animals in the nature and various
characteristics are given to robots. Many animals with four legs have the
ability to walk and even walk new-born. The physiological developments of these
creatures are completed in the mother’s womb and soon after birth, bone and leg
muscle groups are available. It is a well-known fact that living beings can
stay in balance by standing up to their legs after birth and carry out their
neurological signals to the muscles of the legs. In this study, we have studied
the robot kinematics and dynamics of 2-legged robot which resembles a 4-legged
robot in the light of this study, and the robotic ability of the robot to stand
on the ground with an artificial neural network(ANN) support. For the dynamic
motion, the planar model of the robot is considered and 7-axis motion equations
are obtained. The aim of the robot is to be able to stand up from the ground
and stay in balance and it is aimed to be realized with the use of an artificial
neural network structure as learning result. Conventional PID control method
has been used for control signals that should be applied to robot joints.
System responses were obtained graphically and the results were evaluated.

Gerçek rasgele
sayı üreteci (GRSÜ) ile rasgele sayı üretmek için deterministik olmayan bir
gürültü kaynağından yararlanılır. Rasgelelik derecesinin daha yüksek olması
nedeniyle GRSÜ, SRSÜ sayı üreticisinden daha güvenli sayı üretir. Bu makalede, insan
hareketleri ile rasgele sayı üreten bir GRSÜ öneriyoruz. Önerilen GRSÜ, hemen
hemen tüm insanların kullandığı mobil telefonlardaki ivme ve GPS sensörlerini
kullanmaktadır. İlk olarak, mobil telefonu taşıyan kişinin 3-D ortamdaki hareketleri
sonucunda ivme ve konum değişimleri android tabanlı bir mobil cihazdan
örneklenerek elde edilmiştir. Daha sonra, elde edilen bu işaretler,
normalizasyon işlemi uygulanarak ham sayı dizilerine dönüştürülmüştür. Son
olarak, sayı dizilerinin istatistiksel özelliklerini iyileştirmek için XOR son
işlemi uygulanmış ve rasgele sayı üretimi gerçekleştirilmiştir.  Kişi yürürken, koşarken ve stabil konumda
iken sensörlerden elde edilen toplamda 15 veri seti oluşturulmuştur. Sayıların
istatistiksel özellikleri NIST test süiti, Skala İndeks ve otokorelasyon ile incelenmiştir.
Önerilen GRSÜ, cep telefonu platformu için uygun, evrensel ve düşük maliyetli
olup kişiye özgü rasgele sayı üretimi mümkündür.
Yaylalardaki Arazi Kullanım Değişiminin Coğrafi Bilgi Sistemi İle Analizi: Giresun Örneği
Authors: Başer Volkan
Published: March 2019

Türkiye’de
yaylalar uzun yıllar hayvancılık ve yazlık dinlenme alanları olarak
kullanılmıştır. Günümüzde ise büyük ölçüde nitelik değiştirerek rekreasyon
amacıyla kullanılan birer tatil ya da dinlenme yeri olmuşlardır. Bu mekanlara
artan talep arazi kullanımında değişime neden olmaya başlamıştır. Turizm
anlayışındaki değişime paralel olarak, iç turizmde rekreasyon/turizm için
yaylalara olan talep artışı, Doğu Karadeniz Bölgesi’ndeki bazı yaylaları turizm
merkezlerine dönüştürmüş ve buralara yapılan turizm yatırımlarını arttırmıştır.
Bu değişim süreci ile birlikte yaylalardaki arazi kullanımı, çevrenin
görünümünde ve ekosistemlerde büyük değişikliklere yol açmıştır. Artan bu talep
arazi yönetimi kapsamında sıkıntıları beraberinde getirmiştir. Sürdürülebilir
olmaktan çıkan yayla alanları her geçen gün doğal kaynaklarını kaybetmektedir.
Çalışma Türkiye’nin Doğu Karadeniz Bölgesindeki Giresun ili yaylalarındaki
arazi kullanımında meydana gelen değişimi incelemektedir. Bu maksatla 1970-2018
yılları arasında yaylalara ait hava fotoğrafları ve haritalar Coğrafi Bilgi
Sistemi (CBS) ile analiz edilmiştir. Yapılan çalışma sonucunda yıllar
içerisinde yaylaların merkez yerleşim alanlarında, bina sayılarında ve yol ağlarında
büyük değişimler gözlemlenmiştir. Çalışma ile yaylalardaki arazi kullanım ve
planlamasına ilişkin sorunları ortaya konmuş, değişimin boyutlarını irdelenmiş
ve çözüm önerileri getirilmiştir.

Authors: OZMEN KOCA Gonca , DOĞAN Şengül
Published: March 2019

Mobil robotların yol planlaması, tek/çok katlı kapalı alan endüstriyel robotik navigasyon uygulamalarında hayati bir öneme sahiptir. Bu çalışmada, çok katlı ve her kat için birden çok katlar arası geçişin mümkün olduğu endüstriyel bir binada mobil robotların yönlendirilmesi için graf arama algoritmasına dayanan bir optimum yol planlaması önerilmiştir. Yol planlaması için başlangıç ve varış noktalarının yer aldığı iki katı içeren 3 boyutlu kübik yüzey baz alınarak mesafe hesaplanmıştır. Dijkstra graf arama algoritması, engellerden sakınarak en kısa yolun bulunması için belirlenen yüzeylerde başlangıç noktasından tüm noktalara olan mesafeleri hesapladığından dolayı çalışmada bu algoritma tercih edilmiştir. Çalışmada mobil robotun yönlendirilmesi için farklı durumları içeren iki farklı senaryo oluşturulmuştur. Bu senaryolar hedef noktasının mobil robotun bulunduğu kattaki başlangıç noktası ile aynı katta ve farklı katta olması durumlarını içermektedir. Makalede, MATLAB ortamında elde edilen en kısa yolu gösteren benzetim sonuçları sunulmuştur.
