Authors: Herdiani Erna Tri , Ilyas Nirwan
Published: December 2018

Bagan kendali yang  paling banyak digunakan dalam pengendalian proses secara multivariat adalah bagan kendali T2 Hotelling. Ada 2 jenis dari bagan kendali  Hotelling yaitu bagan kendali  Hotelling untuk pengamatan kelompok dan individual. Pada tulisan ini membahas bagan kendali  Hotelling untuk pengamatan individual. Bagan kendali ini digunakan untuk memonitor vektor  rata-rata dan matriks kovariansi sampel. Vektor rata-rata dan matriks kovariansi sampel sangat sensitif terhadap titik ekstrim (outliers). Oleh karena itu dibutuhkan estimator vektor rata-rata dan matriks kovariansi populasi yang kekar terhadap data outliers. Salah satu metode yang dapat digunakan untuk mendeteksi data yang mengandung outliers adalah Minimum Covariance Determinant (MCD). Dari hasil perhitungan diperoleh bahwa bagan kendali T2 Hotelling dengan algoritma Fast-MCD lebih sensitif mendeteksi data outliers daripada T2 Hotelling klasik.

Authors: Tinungki Georgina M. , Sunusi Nurtiti i
Published: December 2018

Sparse Principal Component Analysis (Sparse PCA) merupakan salah satu pengembangan dari metode PCA. Sparse PCA memodifikasi variabel-variabel baru yang merupakan kombinasi linear dari  variabel lama (variabel asli) yang dihasilkan oleh metode PCA. Pemodifikasian variabel baru ini dilakukan dengan dengan menghasilkan matriks loading yang sparse sehingga variabel lama yang tidak efektif (memiliki nilai loading sama dengan nol) dapat dikeluarkan dari model PCA. Pada penelitian ini, metode Sparse PCA diterapkan pada data Indikator Kemiskinan Penduduk Indonesia Tahun 2015 yang memuat 13 variabel dan 34 observasi dengan reduksi variabel menghasilkan 4 (empat) variabel baru yang telah mampu menjelaskan 80,1% dari total variansi data. Hasil penelitian menunjukkan, matriks loading yang dihasilkan menggunakan metode Sparse PCA menjadi sparse dengan terdapat 11 elemen (nilai loading) matriks bernilai nol sehingga model yang dihasilkan menjadi lebih sederhana dan mudah untuk diinterpretasikan.

Published: December 2018

Data media sosial saat ini telah banyak digunakan untuk melakukan analisis baik analisis sentimen maupun analisis terkait lainnya. Nyatanya, data yang diperoleh dari media sosial tersebut pada umumnya memiliki kesalahan yang akan mempengaruhi hasil analisis. Kesalahan tersebut berupa penggunaan kata yang tidak baku dan adanya kesalahan ejaan dalam penulisan kata. Solusi yang ditawarkan berupa formalisasi kata dan pengecekan ejaan. Berdasarkan masalah tersebut, akan dibangun modul preprocessing untuk mengatasi dua kesalahan di atas. Metode yang digunakan pada formalisasi adalah mengubah kata ke bentuk formal berdasarkan KBBI sedangkan metode yang digunakan pada pengecekan ejaan adalah spelling correction. Metode spelling correction tersebut terdiri dari tiga yaitu edit distance, bigram dan edit distance + rule. Pada penelitian ini, selain penerapan kedua metode juga akan dilakukan analisis untuk melihat perbandingan hasil pada metode spelling correction. Dari hasil analisis tersebut, diketahui bahwa metode edit distance + rule memiliki akurasi yang lebih tinggi yaitu sebesar 83,39% dibandingkan dengan kedua metode lainnya yaitu edit distance dan bigram. Selain itu, metode edit distance + rule juga memiliki performa tercepat dibandingkan kedua metode lainnya. Secara keseluruhan, metode mengubah kata ke bentuk formal berdasarkan KBBI dan spelling correction telah mampu mengatasi masalah pada dua kasus di atas sehingga dapat meningkatkan akurasi hasil analisis.

Published: December 2018

Objectives. To determine the impact of improvements in housing and HIV clinical parameters on health-related quality of life (HRQOL) in persons with HIV infection experiencing homelessness.

Methods. This prospective cohort study took place in 9 US sites. Local efforts sought to improve HIV and housing status. Longitudinal data analyses determined the impact of changes in housing status, HIV suppression, and CD4 cell counts on HRQOL at 12 months, measured as mental and physical component summary scores.

Results. Among 909 participants enrolled from 2013 to 2016, 75.1% were homeless, 51.6% did not have HIV suppression, and 23.6% had a CD4 count less than 200 cells per cubic millimeter. Median mental and physical component summary scores were 35.4 and 38.9, respectively. These 5 parameters all improved by 6 months. In multivariate modeling, maintaining or achieving stable housing predicted higher PCS at 12 months, but CD4 count and HIV suppression improvements did not. Improvements in housing, CD4 count, and HIV suppression did not predict mental component score at 12 months.

Conclusions. Housing and HIV treatment are necessary but not sufficient to improve HRQOL in this challenging population. The high prevalence of socioeconomic and mental health needs we found support the call for patient-centered comprehensive care.

Published: December 2018

Objectives. To examine patterns of and factors associated with housing stability over time among people living with HIV (PLWH) experiencing homelessness with co-occurring substance use and mental health disorders enrolled in a patient-centered medical home (PCMH) intervention.

Methods. Between September 2013 and February 2017, we ascertained housing trajectories among PLWH in 9 sites in the United States by conducting interviews at baseline, 6, and 12 months after and dichotomized them as improved consistently versus did not improve consistently. We identified covariates affecting housing stability using the socioecological model.

Results. Forty-three percent (n = 198) experienced consistent housing improvement. Participants with history of mental health diagnosis (adjusted odds ratio [AOR] = 1.55; 95% confidence interval [CI] = 1.02, 2.35; P = .04) or trauma (AOR = 1.72; 95% CI = 1.22, 2.41; P = .006) had improved housing status; those with recent injecting drug use (AOR = 0.41; 95% CI = 0.19, 0.90; P = .03) had less consistent housing improvement.

Conclusions. Improved housing stability may possibly reflect the importance of PCMH interventions that integrate housing, health, and behavioral services with patient navigators to address complex needs of PLWH experiencing homelessness.

Published: December 2018

Objectives. To assess changes in perceived external stigma among people living with HIV (PLWH) experiencing homelessness or unstable housing diagnosed with mental health or substance use disorders following an intervention including care coordination and navigation assistance, building trusting relationships, addressing unmet needs, and reducing barriers to seeking and engaging in care.

Methods. This study was part of a national multisite intervention project delivered at 6 geographically diverse sites throughout the United States from September 2013 through February 2017. Participant surveys were conducted at baseline, 6 months, and 12 months. We assessed perceived external stigma, defined as people’s beliefs about others’ attitudes toward them, related to HIV, homelessness, mental health disorders, and substance use disorders with modified stigma scales.

Results. A total of 548 individuals participated. At baseline, more participants reported experiencing any perceived external HIV stigma (81%) than any stigma related to homelessness and mental health or substance use disorders (38.9%). Over time, those reporting any HIV stigma decreased significantly from baseline (81%) to 61.4% and 57.8% at 6 and 12 months, respectively.

Conclusions. PLWH experiencing homelessness or unstable housing with mental health or substance use disorders are impacted by multilayered stigma. Interventions to engage them in care may help reduce stigma.

Aerodynamics and Stability of the Flow in Relatively Long Cyclone Chambers
Authors: Saburov E. N. , Onokhin D. A.
Published: December 2018

The article presents and analyzes the results of an experimental study of the aerodynamics of the flow in the working volume of cyclone chambers of a large relative length, significantly exceeding the length of the chambers that were used in the previous studies. Air supply to the chamber swirler was carried out tangentially from diametrically opposite sides by two inlet channels. The air discharge from the working volume of the chamber was made from the opposite end of the chamber through a round axisymmetric hole. The values of the area of the inlet channels and the diameter of the outlet were varied with replaceable incrustations and clamps. The experiments were performed with the use of laser Doppler anemometry. As a result, previously unknown features of flow formation in the working volume of relatively long cyclone chambers have been determined. The main characteristic values of the working volume flow have determined as well. In particular, the determining influence of the flow core characteristics on its structure in relatively long cyclone chambers has been discovered. The calculated ratios have been chosen to determine these values depending on the geometrical characteristics of the chamber under study. The boundary of the near-wall flow region, in which favorable conditions for the flow instability are created, is determined. Numerical simulation of the flow in the ANSYS Fluent software has been performed. Based on its results, a comparison of the results of numerical simulation, calculated dependencies and experimental data is presented. A comparison of the results demonstrated a completely satisfactory coincidence. Data obtained in the process of research and calculated ratios can be used in engineering practice and are of an interest from the point of view of further study of aerodynamics in a highly swirled flow of cyclone devices in order of to improving the methods of their thermal and aerodynamic calculations.
Parametric Optimization for Automatic Control System of Power Units of 300 MW for the Mode of Variable Pressure of Turbine Inlet Steam
Authors: Kulakov G. T. , Kulakov A. T. , Artsiomenka K. I.
Published: December 2018

The article deals with the problem of parametric optimization of automatic control systems for power units of 300 MW of Lukoml’skaya GRES in the mode of variable pressure of turbine inlet superheated steam. The modernization of automatic power control systems of all power units of Lukoml’skaya GRES was carried out in the nineties of XX century for the last time. At the moment, these systems no longer meet all the requirements of the new standard, which regulates the participation rates of thermal power units in the normalized primary frequency control and in automatic secondary control of frequency and active power flows. According to this standard, the time to achieve the half value of the required power change should be 10 seconds within the normal and emergency reserves; the time to achieve the full value of the required power change should be 30 seconds within the normal reserve and 2 minutes within the emergency one. The construction of the Belarusian NPP is also being completed; its first unit will be put into operation in 2019, and the second one–in 2020. After the launch of the NPP, the Lukoml’skaya GRES power units will be necessitated to operate in a wide range of load changes. It is for these reasons that it is necessary to improve the efficiency of power units in particular and of the entire power plant in general. This can be achieved with the help of the outlined method of parametric optimization of a typical system of automatic control of power units, which allows improving the quality of control of turbine inlet steam power and pressure. The results of computer simulation of transient processes in the system illustrate the technique described in this article and confirm its correctness and undoubted advantages over other methods of optimization of typical systems of automatic control of power units.

Authors: Ol’shanskii A. I. , Zhernosek S. V. , Gusarov A. M.
Published: December 2018

New ways of experimental data processing by generalized complex variables that are characteristic of the drying process are presented. The authors presented the results of a study of heat and moisture exchange in the convective drying of thin flat moist capillary-porous materials. As a result of the processing of the experimental data, equations were obtained for determining the densities of heat fluxes, average integral temperatures, drying time and moisture evaporation rate in the second drying period. The relationship between the densities of heat fluxes in the first and second periods and the temperature change in the second period is revealed. The dependence for calculating the temperature of the material in the period of the falling drying rate taking into account the heat that is expended to heat the wet body is presented. The equations for determining the temperature in the second period by the temperature coefficient of drying, the rate of heating of the wet material and the rate of heating of the wet body are presented as well. An equation for determining the drying time by the value of the rate of loss of moisture content of the material is given. A mathematical expression for calculating the intensity of moisture evaporation in the first and second drying periods depending on the ratio of moisture content in the first period and the current in the second moisture content one is set. The conditions of a regular regime for heat and moisture exchange for a second drying period are adduced. The authors consider the possibility of determining the rate of heating of wet material by the heating rate using the graphical differentiation of the temperature function, which is described by the curve, as a function of time in the second drying period. The problems of using the methods of the theory of the regular regime for heating wet bodies during the investigation of the drying process are considered. The formulas for determining the rate of heating of the body and the rate of loss of moisture content are given. The accuracy of the experimental data processing and the reliability of the experimental equations obtained for all the materials under study are verified. As a result of the research, all the basic kinetic characteristics necessary for the calculation of heat and moisture exchange in the drying process have been determined.

Published: December 2018

Desde las últimas décadas del siglo XX se produce un debilitamiento de los movimientos vecinales en las periferias urbanas españolas. En ese contexto temporal se examina, mediante análisis documental y metodología cualitativa, el significado de tales movimientos en dos barrios desfavorecidos de Santa Cruz de Tenerife. Los resultados revelan que la acción ciudadana adquiere desigual alcance en los casos seleccionados. Aunque estos barrios presentan rasgos comunes, la distinta orientación de sus luchas ciudadanas ha determinado que los residentes tengan diferentes posibilidades de ejercer su derecho a la ciudad.
Evaluando la influencia de la calidad de la distancia peatonal en la cobertura de paradas del metro ligero de Granada (España)
Authors: Talavera García Rubén , Valenzuela Montes Luis Miguel , Soria Lara Julio Alberto
Published: December 2018

Aunque las características del entorno urbano y social tienen una marcada influencia en la distancia peatonal al transporte público, existe una escasa atención a este fenómeno en el contexto de los análisis de accesibilidad. Sin embargo, considerar la calidad de la distancia peatonal en la evaluación de la accesibilidad podría constituir una herramienta útil para conseguir una mayor y mejor integración del transporte público en los entornos urbanos. En este artículo se diseña la herramienta Q-WD: Calidad de la Distancia Peatonal (Quality of Walking Distance) testeándola en el caso de la ciudad de Granada, y en concreto en varios entornos de movilidad vinculados a la línea de metro ligero. Los resultados muestran cómo la cobertura de las paradas se reduce en aquellos casos en los que la calidad peatonal de los entornos de parada es baja, mientras que los entornos de parada con alta calidad peatonal producen una extensión de la cobertura de parada del transporte público. Asimismo, los resultados de la aplicación de la herramienta Q-WD evidencian cómo el recuento total de población servida varía en los entornos peatonales cuando se considera la calidad de la distancia.

Perspectivas de funcionamiento del Trasvase Tajo-Segura (España): efectos de las nuevas reglas de explotación e impulso de la desalinización como recurso sustitutivo
Authors: Morote Seguido Álvaro Francisco , Rico Amorós Antonio Manuel
Published: December 2018

El Trasvase Tajo-Segura se ha convertido desde su inauguración en 1979 en una de las infraestructuras hidráulicas que más tensiones interterritoriales ha originado en España. A ello se une su valor estratégico para el desarrollo de las provincias del sureste peninsular, donde atiende consumos agrícolas y urbano-turísticos con grandes implicaciones sociales y económicas. El objetivo de este trabajo es analizar las causas y las consecuencias del funcionamiento del Trasvase Tajo-Segura con la reciente modificación de sus normas de explotación (límite de no trasvase cuando en los embalses de cabecera almacenen menos de 400 hm3) y el impulso de la desalinización en la cuenca receptora como sustitución a los trasvases. Para ello se han analizado los efectos del funcionamiento de las nuevas normas de explotación y se plantean posibles alternativas para resolver un conflicto que se agrava durante cada ciclo de intensa y prolongada sequía sin que el Estado ni las autonomías, a través de la planificación hidrológica, hayan dado una respuesta satisfactoria a las regiones cedentes y receptoras.

CİNSİYETE DAYALI ÜCRET EŞİTSİZLİĞİNİN AVRUPA BİRLİĞİ VE TÜRKİYE KAPSAMINDA DEĞERLENDİRİLMESİ
Authors: ŞEN Mustafa
Published: December 2018

Günümüzde kadınlar çalışma hayatı
içerisinde birçok sorunla karşı karşıya kalmaktadırlar. Özellikle işe alınmada,
iş esnasında ve işe son verilmede kadınlar sürekli ayrımcı davranışlara
uğramaktadırlar. Bu ayrımcı davranışlar içerisinde önemli sorunlardan bir
tanesi de erkek çalışanlar ile aynı eğitim seviyesine sahip ve aynı işi yapan
kadın çalışanların erkek çalışanlara kıyasla daha düşük ücretler almaları
olarak ifade edilen ücret eşitsizliği sorunudur. Uluslararası Çalışma
Örgütü’nün (ILO) 2016 yılında yayınlamış olduğu Küresel Ücret Raporu’nda, kadın
ve erkek çalışanlar arasındaki ücret eşitsizliğinin geçmişten günümüze
azalmakla beraber halen daha devam ettiği belirtilmektedir. Ayrıca raporda,
çeşitli ülkelerde yapılan araştırmalar kapsamında kadın ve erkek çalışanlar
arasında cinsiyete dayalı saatlik ücret farkının %50’lere kadar vardığı ifade
edilmektedir. Diğer yandan Avrupa Birliği’nde (AB) cinsiyete dayalı ücret farkı
2014 yılında %16,6 oranında gerçekleşmiştir. Türkiye’de ise eğitim durumlarına
göre cinsiyete dayalı ücret farkı 2014 yılında okul öncesi-ilköğretim-ortaokul
düzeyinde %16 iken yüksek lisans ve doktora düzeyinde ise artarak %23,3
oranında gerçekleşmiştir. Çalışmanın amacı, AB ülkeleri ve Türkiye’de kazanç
yapısı araştırmaları kapsamında kadın ve erkek çalışanlar arasındaki ücret
eşitsizliğini ortaya koymaktır. Çalışmanın bir diğer önemli amacı da ücret
eşitsizliğini önlemeye yönelik düzenlemeler kapsamında görüş ve önerilerin
sunulmasıdır.

Establishing meter under registration on domestic premises with roof tanks
Authors: Pearson D. , Preston N. , Al-Naimi A. , Smith C.
Published: December 2018

The Public Authority for Electricity and Water in Oman carried out an initial estimate of legitimate domestic night consumption (LDNC) based on an assessment of night consumption surveys of over 1,500 premises. However, no allowance for meter under-registration (MUR) had been applied in the assessment. This paper reports on a study to identify MUR in Oman, which can be applied to the results of the survey for LDNC. All premises in Oman are required to have a roof tank in order for customers to maintain their supply in the case of mains water supply interruptions. Regulations require that the roof tanks provide at least two days' storage. It is believed that roof tanks could have a significant impact on MUR due to the long ‘tails’ generated by the operation of the ball valve controlling the refilling of the roof tank. It was therefore decided that a study should be carried out to review the main drivers for MUR and the likely level of MUR to be expected in Oman, particularly at low flows such as those experienced at night time when a single toilet is flushed. In regards to the sample of properties included in the MUR survey, it was suspected that in the case of apartment blocks, the revenue meters will normally be located after the roof tank, in which case the roof tank will not influence MUR. This study sought to confirm this. Half the premises were fitted with an unmeasured flow reducer on a bypass so that the potential of such devices to reduce MUR could be investigated. Oman has continuous water supply. There were no supply interruptions during the study. The paper describes details of the plumbing arrangements developed for the study and the results established as part of the programme. It also takes the opportunity to report on the level of daily and night consumption experienced on the study area.

Authors: Abou-Seri Sahar M. , Taha AlShaimaa M. , Mohamed Mona A. , Abdelkader Nour M.
Published: December 2018

Background:

Sulphonylureas are the oldest and commonly used to treat diabetic patients, but its efficacy declines by time. It was reported that quinazoline nucleus exhibits a potent hypoglycemic effect in diabetic animal models.

Objective:

The current study aimed to synthesize new quinazoline-sulfonylurea conjugates and evaluate their hypoglycemic effects in alloxan-induced diabetic rats.

Methods:

The conjugates were synthesized by bioisosteric replacement of 5-chloro-2-methoxybenzamide moiety in glibenclamide or 1,3-dioxo-3,4-dihydroisoquinoline moiety in gliquidone with 6,7-dimethoxy-4-oxoquinazoline moiety (compounds 4a-4d, 9b-9c and 10b-10d). Diabetes was induced in rats by a single i.p. administration of alloxan, followed by treatment with the synthesized conjugates (5mg/kg Body weight).

Results:

All conjugates showed hypoglycemic effects with different efficacy indicated by the reduction in blood glucose and elevation of insulin levels. Moreover, these conjugates up-regulated the expression of pancreatic glucose transporter 2, muscle glucose transporter 4, and insulin receptor substrate-1 genes, compared to the diabetic group. A normal pancreatic tissue pattern was noticed in diabetic rats treated with compounds 9b, 9c, and 10c.

Conclusion:

Conjugation of sulfonylurea with quinazoline (especially 9b, 9c, 10c) possessed a significant hypoglycemic effect through improving blood insulin level and insulin action and consequently increased the glucose uptake by the skeletal muscles.

Authors: Belanova Anna , Beseda Darya , Chmykhalo Victor , Stepanova Alisa , Belousova Mariya , Khrenkova Vera , Gavalas Nikolaos , Zolotukhin Peter
Published: December 2018

Background:

Berberine has multitudinous anti-cancer stem cells effects making it a highly promising
candidate substance for the next-generation cancer therapy. However, berberine modes of action predispose it to
significant side-effects that probably limit its clinical testing and application.

Materials and Methods:

HeLa cells were treated with two concentrations of berberine (30 and 100 µM) for 24
hours to assess the functioning of the NFE2L2/AP-1, NFκB and HIF1A pathways using 22 RNAs expression
qPCR-based analysis.

Results:

Berberine effects appeared to be highly dose-dependent, with the lower concentration being capable of
suppressing the NFκB functioning and the higher concentration causing severe signaling side-effects seen in the
HIF1A pathway and the NFE2L2 sub-pathways, and especially and more importantly in the AP-1 sub-pathway.

Conclusion:

The results of the study suggest that berberine has clinically valuable anti-NFκB effects however
jeopardized by its side effects on the HIF1A and especially NFE2L2/AP-1 pathways, its therapeutic window
phenomenon and its cancer type-specificity. These, however, may be ameliorated using the cocktail approach,
provided there is enough data on signaling effects of berberine.
Pengaruh zonasi dalam kandang closed house terhadap kadar amonia dan dampaknya pada kualitas daging broiler di musim penghujan
Authors: Renata Renata , Sarjana Teysar Adi , Kismiati Sri
Published: December 2018

This experiment was conducted to determine the effect of zonation in closed house on ammonia levels and its impact on broiler chicken quality in the rainy season. The research was held in closed house, Faculty of Animal Husbandry and Agriculture, Diponegoro University. Three hundred and sixty broilers were divided into 24 groups (4 treatment, 6 placement groups of broiler): T1 (Zone 1, at the inlet position of the cage), T2 (Zone 2; ¼ of the length of the cage), T3 (Zone 3; ½ from the length of the cage ); T4 (Zone 4; ¾ of the length of the cage). During the study of ammonia levels, the temperature, humidity, and wind velocity inside and outside the cage were taken to obtain an overview of several factors that contribute to ammonia levels. The parameters observed were water holding capacity, pH, color, moisture content, fat content, and protein content. Water holding capacity and the color of the upper thigh meat increased significantly in the zone near the outlet (p <0.05), but the water holding capacity and the color of the lower thighs and breast meat did not increase (p> 0.05) in the zone near the outlet, but it has a darker meat color on the zone near the outlet. The pH did not show any significant difference (p> 0.05) in the zone near the outlet. Water content followed by fat content of breast meat showed no significant difference (p> 0.05) due to zoning. Breast protein content significantly increased (p <0.05) in the zone near the outlet. It was concluded that placement in the zone near outlet had impact on the increase of water holding capacity, color, and protein content. Nevertheless, an increase in meat protein in the zone near the outlet is not followed by increased meat protein mass.
A Tactical Framework for Market Penetration with a Multidimensional Organization
Authors: Bigley Joel D.
Published: December 2018

A critical element to the growth opportunities in existing markets and new markets in neighboring sectors is penetration strategies. An entrepreneurial business that is interested in leveraging synergies to grow profitability must understand the dynamic nature of the market so that a suitable strategic posture can be taken. This strategy could be driven by tactical and deliberate action, or another exogenous force. The opportunities are there in many sectors and customers of multinational enterprises (MNE’s) exist almost everywhere. Cross border B2C e-commerce is expected to double by 2022 according to Forrester Research. So, how do MNE’s efficiently penetrate within segments and across geographic markets? Scaling opportunities exist across a multidimensional design (MDD) and the synergy opportunities between sites. This article describes methods and capabilities of market penetration ideally suited for an MDD. These themes emerged in the data when MDD leaders were asked about the roles of each function. In this case study an MNE utilized a multidimensional organization design to reach customers in many parts of the world. The author presents findings from this case and ultimately extracts ten propositions to guide client penetration strategy. Absent these measures, risk of revenue loss is enhanced significantly.

Some tables and figures are presented to reveal the performance of the presented method.
An analysis of dependence between oil price and stock market with Copula-Garch approach: An empirical analysis from Istanbul stock exchange
Authors: Metin-Karakas Ayse
Published: December 2018

This paper examines the dependence structure between National 100, National 50, and National 30 Indices of Istanbul Stock Exchange and international Brent oil price by using copula-GARCH method. Linear correlation has a serious deficiency. Whereas copula method is not invariant under non-linear strictly increasing transformation. Meanwhile the dependence measures derived from copulas can overcome this shortcoming and have broader applications. Furthermore, copulas can be used to describe more complex multivariate dependence structures, such as non-linear and tail dependence. In this study, we covered the period from March 14, 2001 to March 23, 2018 by using daily prices. Our findings suggest that there is a weak dependence structure between Istanbul Stock Exchange and Brent oil prices which may have significant implications for policymakers, investors and risk managers in terms of the relationship between oil prices and the stock market.

Chebyshev wavelet collocation method for Ginzburg-Landau equation
Authors: Secer Aydin , Bakir Yasemin
Published: December 2018

The main aim of this paper is to investigate the efficient Chebyshev wavelet collocation method for Ginzburg-Landau equation. The basic idea of this method is to have the approximation of Chebyshev wavelet series of a non-linear PDE. We demonstrate how to use the method for the numerical solution of the Ginzburg-Landau equation with initial and boundary conditions. For this purpose, we have obtained operational matrix for Chebyshev wavelets. By applying this technique in Ginzburg-Landau equation, the PDE is converted into an algebraic system of non-linear equations and this system has been solved using MAPLE computer algebra system. We demonstrate the validity and applicability of this technique which has been clarified by using an example. Exact solution is compared with an approximate solution. Moreover, Chebyshev wavelet collocation method is found to be acceptable, efficient, accurate and computational for the non-linear or PDE.
