The main drawback of the modern power supply system is centralization. Renewable energy is a promising alternative for supplying electricity to remote settlements. Solar energy is more preferable, since it is least dependent on the geographical location. (Research purpose) The research purpose is in studying the possibilities of creating an autonomous renewable energy system based on solar photoconvertors for remote villages. (Materials and methods) Authors examined small rural settlements in various climatic regions of the Russian Federation and Uzbekistan, identified promising regions for solar-powered systems similar in climatic and socio-economic parameters – the Krasnodar Territory and the regions of Uzbekistan. There was used data from the NASA POWER project for analysis. (Results and discussion) The article presents the comparison of a diesel generator and a renewable solar-diesel system as an autonomous source of electricity for small settlements. Due to the lack of sun in winter and due to lower temperatures, there is a need for an additional source of energy. (Conclusions) The article presents the methodology for assessing the technical and economic potential of renewable energy sources in the regions under consideration. Due to the high solar activity and geographical location, the cost of energy in the regions of Uzbekistan was 0.153, 0.155, 0.166 dollars per kilowatt-hour for hybrid renewable energy systems and 0.387, 0.371, 0.401 dollars per kilowatt-hour for a diesel generator. In the Krasnodar Territory these costs are 0.138 dollars per kilowatt-hour for a hybrid system and 0.316 dollars per kilowatt-hour for a diesel generator. It is possible to create fully autonomous power supply stations in these regions based on solar energy stations. For this purpose it is necessary to add an energy source that will be used during periods of insuﬃcient solar activity. The most promising solution is the use of a wood gas source.

Objective: The COVID-19 pandemic is an important cause of morbidity and
mortality, which has had a negative impact worldwide. Our aim was to
describe clinical findings and outcomes of SARS-CoV-2 viral infection
and Covid-19 disease cared for at a large pediatric tertiary care
hospital during the first year of the pandemic. Methods: Patients aged 1
month to 18 years who were diagnosed as having COVID-19 between March
2020 and April 2021 were included. The files of patients diagnosed with
covid-19 were reviewed retrospectively. Results: 467 children were
included in the study. There were 34 (7.3%) patients under one year of
age, 111 (23.8%) between 1-5 years, 98 (30.4%) between 5-10 years, 142
(30.4%) between 11-15 years, and 82 (17.6%) age over 15 years. Fever
(88.2%), vomiting (32.4%), and diarrhea (29.4%) in patients aged
under 1 year, sore throat (36.6%) in patients aged 11-15 years, and
dysgeusia (11%), anosmia (14.6%), headache (18.3%), malaise (40.8%),
myalgia (28%), and dyspnea (17.1%) in those aged over 15 years of age
were found significantly more common compared with the other age groups
(p<0.05). Thirty-five (7.5%) patients were asymptomatic, 365
(78.1%) had mild disease, 35 (7.5%) were moderate, 27 (5.8%) were
severe, and five (1.07%) were critical. Leukocyte count, erythrocyte
sedimentation rate, ferritin, and C-reactive protein values were
significantly higher in hospitalized patients. Four patients died during
the study period (0.8%, 4/467). Conclusion: While SARS-CoV-2 infection
may be asymptomatic and Covid-19 disease usually has a mild clinical
course, some children have severe disease or mortality.
Evolution of properties of macadamia husk throughout gasification: hints for a zero-waste energy production system

Published: October 2021

In-depth information about the transformation of biomass during
gasification is the key to the sustainable development of this
technology. This study elucidated the evolution of physico-chemical
properties of macadamia husk throughout relevant industrial gasification
conditions. The technical characteristics combined with high kinetics
highlighted the suitability of this feedstock for gasification.
Non-porous chars with very low surface areas were observed throughout
the conversion, which minimizes the potential to use the residues after
gasification as adsorbents. Nevertheless, multiple carboxyl and hydroxyl
functional groups were present on the char surface. Moreover, an
extraordinarily high K content was detected (up to 86 wt% of the char’s
total inorganic elements) and evenly distributed on the char surface.
Such results consolidated the idea of combining the production of energy
and cheap bio-fertilizers using the gasification of macadamia husk. The
resulting database offered interesting hints for the development of
zero-waste energy production systems with biomass gasification.
Ölü Gömme Gelenekleri Bağlamında Berel Kurganları
Authors: Kutlu Mehmet
Published: October 2021

Altay Dağlarının güneybatı ucunda bulunan Berel Vadisi’nde 1865 yılında Wilhelm Radloff tarafından kazısı gerçekleştirilen kurganlarda permafrost katmanları tespit edilmiştir. Bu özelliğe sahip kurganların merkezindeki derin çukura ahşap tomruklardan inşa edilmiş defin odaları konumlandırılmıştır. Söz konusu ahşap defin odalarında ve tek parça tomruktan oyulmuş ahşap lahitte insan ve çok sayıda at gömüleri tespit edilmiştir. Ancak zamanın kazı yöntemleri ve arkeolojik buluntuların korunması imkânlarının yeterli olmaması nedeniyle söz konusu insan ve at gömüleri korunamamıştır. Daha sonra Berel Vadisi’ndeki kurganlar yaklaşık 150 yıla yakın süre boyunca kapsamlı bir şekilde kazılmamış ve incelenmemiştir. Bu durum 1998 yılında Prof. Dr. Zainolla Samashev’in ekibiyle birlikte Doğu Kazakistan Arkeolojik ekspedisyonu kapsamında Berel’de geniş çaplı kazılar yürütmeye başlamasıyla değişmiştir. Permafrost (kalıcı don) katmanları olgusunun 10. ve 11. Kurganlarda da saptanması sıradan kurganlarda korunamayan organik materyallerden yapılmış sanat eserlerinin yanı sıra insan ve at kalıntılarının günümüze ulaşmasına ve incelenebilmesine olanak sağlamıştır. Bu çalışma, Berel kurgan mezarlığında bulunan İskit/Saka, Hun-Hsiyen Pi ve Göktürk dönemine ait kurganları ölü gömme gelenekleri bağlamında ele almaktadır. Antropolojik araştırmalar ve ölü gömme gelenekleri üzerine yapılan değerlendirmeler sonucu ortaya konulan benzerlikler, İskit/Saka döneminden Göktürk dönemine kadar kültürel süreklilik veya devamlılık olgusunu kanıtlamaktadır.
Alper Canıgüz'ün Kan ve Gül Romanı Örneğinde Çevirmen ve Dünyası
Authors: Uysal Ünalan Saniye
Published: October 2021

Son yıllarda çevirmen kimliklerinin gerek çeşitli araştırmalarda gerekse kurmaca hikâyelerde konu edildiğini ve çevirmenin bir özne olarak ele alındığını görüyoruz. Bu yönelim, kültür bilimlerinde kültürel dönemeç (cultural turn) ekseninde gerçekleşen paradigma değişikliğiyle birlikte kültüre, kimliğe ve yazınsal metinlere yaklaşımdaki yeniliklerle ilişkilendirilebilir. Öyle ki, çeviri sürecinde dokunulmaz bir ölçüt olarak ele alınan kaynak metinden ziyade 1980’li yıllardan sonra çevirmenin nasıl tanımlandığına, hangi konuma sahip olduğuna ve nasıl bir tutum sergilediğine odaklanılmaktadır. Akademik çalışmalar, çevirmenlerin görünürlüğünün artmasına, çevirmene ve çeviriye verilen değer açısından olumlu yansımalara neden olmaktadır. Kültürel dönemeç bağlamında da Bachmann-Medick’in ifade ettiği gibi, kültür ve kültürün ortaya koyduğu söylem ve ürünler arasında önemli bir yeri olan edebiyat hermeneutik açıdan yorumlanabilir bir obje olarak ele alınmak yerine, dâhil olduğu toplumsal ve kültürlerarası etkileşim alanları kapsamında değerlendirilmektedir. Bu anlamda özellikle iki yaklaşıma değinmek gerekir. Clifford Geertz ile Stephen Greenblatt kültürbilimsel bir yaklaşımla kültürün metinsel boyutlarına vurgu yapmışlar ve kültür-metin ilişkisinin önemini ortaya koymuşlardır. Kültür kavramının tanımlanması konusunda yeni bakış açıları sunan bu paradigma değişiminin izlerini özellikle çevirmen figürlerini ön plana çıkaran kurgusal eserlerde de tespit etmek mümkün. Bu bağlamda kurgusal olarak inşa edilen çevirmen figürlerinin de bu değişimden ne ölçüde etkilendiği ortaya çıkmaktadır. Bu çalışma, kültürler ve metinler arasında bir dolaşım ağı ve etkileşim alanı oluşturan çevirmen figürlerinin edebî eserlerde ne şekilde kurgulandığını incelemeyi hedeflemektedir. Bu çerçevede, yazın eserlerinin ve filmlerin kurmaca dünyalarında gerek fiziksel gerekse ruhsal açıdan son derece olumsuz kurgulanan çevirmen karakterlerin, günümüz eserlerinde nasıl yansıtıldığı, mesleki kimlik inşasında edebî metinlerin çevirmeni ne şekilde kurguladığı ve kurmaca dünyada ne şekilde var ettiğini somut bir örnek üzerinden göstermek amacıyla Alper Canıgüz’ün ilk baskısı 2017’de yapılmış olan Kan ve Gül. Bir Kara Dejavu isimli romanı ele alınacak ve nitel araştırmada elde edilen veriler, betimsel olarak analiz edilmektedir. Bu kapsamda romanın başkahramanı olan çevirmen figürünün incelenmesinde çeviribilimsel yaklaşımların yanı sıra, kültürbilimsel yaklaşımlara başvurulacak ve ayrıca anlatım kuramından da yararlanılmaktadır.
Halikarnas Balıkçısı'nda Deniz Motifleri ve Poseidon
Authors: Arseven Tülin
Published: October 2021

Cevat Şakir Kabaağaçlı Türk edebiyatının önemli yazarlarından biridir. Eserlerinde Halikarnas Balıkçısı müstearını kullanmıştır. Çünkü tarihteki adıyla Halikarnassos yani Bodrum, onun için önemli, özel bir yerdir. Hemen hemen bütün eserlerinde Bodrum ve ona özgü güzellikleri işlemiştir. Bodrum’un yanı sıra Ege Denizi ve Akdeniz ile bunların kıyılarını ve doğal güzelliklerini, insanlarıyla bir bütün olarak ele almıştır. Bu bütünün içinde insanların acıları, yaşam ve ekmek kavgaları, inanışları, anlatıları da vardır. Cevat Şakir denizi de vatanın parçası sayar. Denizi ve toprağıyla Anadolu, onun için koca bir yurttur. Edebiyatımızda Mavi Anadolu Hareketi’nin de öncülerinden olan Cevat Şakir, Batı uygarlığının köklerini Anadolu’ya dayandırır. Eserlerinde Anadolu ve Mavi Anadolu’yu bütün güzellikleriyle anlatmaya çalışır. Bu arada eserlerinde mitolojiye ait öğelere, anlatılara, söylencelere de büyük ölçüde yer verir. Yer verdiği mitolojik öğelerden biri de Poseidon’dur. Cevat Şakir Kabaağaçlı’nın eserlerinde mitolojik bir kişilik olarak Poseidon’un nasıl yer aldığı, orijininden farklılıklar taşıyıp taşımadığı, nasıl ifadesini bulduğu meselesi bu çalışmanın ana problemidir. Cevat Şakir’in öncülük ettiği Mavi Anadolu düşüncesi, onu eserlerinde mitolojik öğelere yer veren diğer yazarlardan ayrı bir yere koymaktadır. Buradan hareketle, nitel araştırma yöntemlerinden doküman analiziyle yapılan bu çalışmada Cevat Şakir’in eserleri Poseidon miti odağında taranmıştır. Araştırmada Poseidon’a ait söylencelerin eski çağlardan günümüze varlığını sürdürme gayreti/biçimi, Halikarnas Balıkçısı’nın eserlerindeki yansıması, bir başka deyişle modern anlatıdaki izleri belirlenmeye çalışılmıştır.
How has the Nobel Prize Affected the Canonisation of Japanese Literature?
Authors: Çetin Güven Devrim
Published: October 2021

Tanizaki, Kavabata, Mişima ve Oe gibi seçkin yazarların İngilizce tercümede yeniden keşfedilmeleri sayesinde, Japon edebiyatı 1950’lerden 70’lere kadar olan süreçte ABD ve Batı Avrupa’da en çok okunan Avrupa-dışı çeviri edebiyatı olmuştur. Bu yeniden keşif, diğer Avrupa dillerine ve Avrupa-dışı dillere yeni çevirileri teşvik etmiş ve esinlemiştir. 1990’lardan itibaren Murakami ve Yoşimoto gibi postmodern yazarlar da küresel çapta ün kazanmıştır. Dünyaya mal olmuş bu yazarların hepsi ilginç bir şekilde Nobel Edebiyat Ödülü’yle bağlantılıdır: ya Kavabata ve Oe gibi ödülü kazanmış, ya Tanizaki ve Mişima gibi ödüle aday gösterilmiş, ya Murakami gibi ödül adayı olarak düşünülmüş, ya da Yoşimoto gibi sadece, bir gün bu ödülü almanın hayalini kurmuşlardır. Nobel ödülünün evrensel boyuttaki cazibesi, ona layık görülen yazarları “fiilen” dünya yazarı olarak kanonlaştırmasıdır. II. Dünya Savaşı’nda büyük bir hezimet yaşamış olan Japon toplumu için savaş sonrası dönemde bu “şeref,” daima özel bir anlam ifade etmiş ve yenilgi sonrasında bir düzelmenin ve toparlanmanın simgesi olarak görülmüştür. Nobel’in böylesine ulusal ve uluslararası cazibelere sahip olması gerek okurlar gerekse medya nezdinde, ödüle ve ödül adayı yazarlara karşı büyük ilgi uyandırmaktadır. Bazen bunaltan bu aşırı ilgi nedeniyle 1960’ların Nobel adayı Mişima Tayland’a kaçmıştır. Günümüzde ise bir süredir adı Nobel ile anılan Haruki Murakami’nin, kendilerini Haruki-ci olarak adlandıran hayran-okurları Nobel ödül programlarını, Dünya Kupası final maçı izler gibi seyretmektedir. Bu makalede, Japon edebiyatı yazarları ile “Nobel Edebiyat Ödülü” adı verilen kültürel evrenselliğin simgesi haline gelmiş fenomen arasındaki karmaşık ilişkiler ele alınmıştır. Nobel ödülüne aday olarak düşünülmenin, aday gösterilmenin, ödülü kazanmanın veya kazanamamanın adı geçen yazarların evrenselleşmesine nasıl katkıda bulunduğu sorusuna cevaplar aranmıştır.

Authors: Büyükokutan Töret Aslı
Published: October 2021

Tıp fakültesine yeni başlayan öğrencilerin mesleğe geçişlerini temsil eden beyaz önlük giyme töreni, hekimlik mesleğindeki ilk geçiş ritidir. Öğrencilerin aile ve yakınlarının da katıldığı törende, öğretim üyeleri, öğrencilere beyaz önlük giydirmektedir. Önlük giyme töreninin ardından öğrenciler hep birlikte temelini Hipokrat yemininden alan bir andı okumaktadır. Beyaz önlüklerle çekilen toplu fotoğrafların ardından tören sona ermektedir. Yazıda, Eskişehir Osmangazi Üniversitesi Tıp Fakültesi hekimleri, öğrencileri ve öğrencilerin aileleriyle yapılan görüşmelerden hareketle, hekimlik mesleğindeki Beyaz Önlük Giyme töreni üzerinde durulmuştur. Törenin iki temel sembolü olan beyaz önlüğün öğretim üyeleri tarafından öğrencilere giydirilmesi ve hekimlik andının edilmesi uygulamaları yapısal ve işlevsel özellikleriyle ele alınmıştır. Tespit ve değerlendirmeler sonucunda, beyaz önlük giyme töreninin, hekim adaylarının hekimlik mesleğine kabulü açısından önemli bir görevi yerine getirdiği görülmüştür. Öğretim üyeleri, öğrencilere beyaz önlüklerini giydirirken hem onları tebrik edip onurlandırmakta hem de değerli bir mesleğe girişlerini kutlamaktadır. Kendine özgü birtakım kuralları ve düzeni olan törenin her yıl tekrarlanması bir taraftan sürekliliğini sağlarken diğer taraftan öğrencilere tıp etiği kurallarını da aktarmaktadır. Tıp mesleğinin yüceliğine ve sağlığın kutsiyetine dair yapılan konuşmalarla öğrencilerin grup kimliğinin oluşması sağlanmaktadır. Hekimlik andı ile öğrenciler ortak bir hissi ve duygusal deneyimi paylaşmaktadır. Evlatlarının saygın bir mesleğe törenle girişini görmek aileleri de onurlandırmaktadır.
Arabidopsis thaliana GTS1 transcripts are activated by yeast extract

Published: October 2021

WD40 repeat-containing proteins participate in DNA-protein and
protein-protein interactions and positively regulate plant stress responses.
GTS1, known as a WD40 repeat-containing protein, works as a scaffold protein
and is important in ribosome biogenesis and also biomass accumulation. In
this study, we evaluated the GIGANTUS1 (GTS1) gene expression in response to
biotic and abiotic stress factors in Arabidopsis thaliana plants. In
addition, we grew and characterized A. thaliana gts1 mutant (T-DNA
SALK_010647) in order to observe the effects of its absence on plants.
According to our results, 100-200 mM abscisic acid (ABA) and 100-200 mM
sodium chloride (NaCl) treatment did not cause any changes in GTS1 gene
expression, while only 6 h of 1 g/l and 2 g/l yeast extract (YE) treatment
negatively affected GTS1 expression in 10-day-old plant explants. After 10
and 30 days of YE treatment, GTS1 gene expression was upregulated, and as a
consequence plant growth efficiency was reduced. We thus concluded that
through the downregulation of GTS1 transcripts, we could obtain better
growth and/or higher biomass, which seems to be a good option for
agricultural recruitments.

Authors: Guzel Kara , Ulger Mahmut , Kahraman Ahmet
Published: October 2021

The phytochemical contents of Salvia virgata mericarps and the antioxidant
and antimicrobial activities of its ethanol extract were studied for the
first time. S. virgata mericarps were collected in the province of Trabzon,
Turkey. Chemical analyses were performed using chromatographic methods. The
total phenolic and flavonoid contents and antioxidant potential were
measured using Folin-Ciocalteu, Al(NO3)3, and DPPH radical scavenging
activity methods, respectively. The antimicrobial activity was evaluated
using the microdilution method for all the tested bacterial and fungal
strains, with the exception of Mycobacterium tuberculosis for which the
resazurin microtiter plate method was applied. The mericarps were rich in
glutamic acid (3934 mg/100 g), potassium (12578.8 ?g/g), calcium (12092.0
?g/g), and dietary fibers (35.565 g/100 g). The total phenolic and flavonoid
contents were 2.50 ?g GAE/mg extract and 0.34 ?g QE/mg extract,
respectively. The most effective DPPH free radical scavenging activity
determined for the highest applied concentration was 92.44%. The ethanol
extract obtained from the mericarps was found to be as effective as the
reference drug ampicillin (MIC value = 125 ?g/mL) against the nosocomial
pathogen Acinetobacter baumannii. In conclusion, S. virgata mericarps
provide good nutritional value with low amounts of carbohydrates and high
dietary fibers, amino acids, minerals and total phenolic and flavonoid
contents and medicinal properties.
On Bangia atropurpurea (Bangiales, Rhodophyta), the strictly protected red alga in Serbia
Authors: Mitrovic Aleksandra , Simic Snezana
Published: October 2021

The first observation of the red alga Bangia atropurpurea (Bangiales,
Rhodophyta) in Serbia was in 1991 in the Trgoviski Timok River (Eastern
Serbia). From 1991 to 2017, the species was sporadically observed at four
more locations in three hillmountain rivers in Southwestern (the Gvozdacka
River and the Raska River) and Eastern (the Nisava River - two localities)
Serbia. More intensive research on this alga was carried out from 2017 to
2020, and a total of 220 localities in 132 hillmountain watercourses were
studied. Bangia atropurpurea was recorded at six locations in Southwestern
and Eastern Serbia. Five of these locations represent new B. atropurpurea
localities in Serbia (the Brusnicka River, the Golijska Moravica River, the
Panjica River, the Resava River, and the second locality in the Trgoviski
Timok River), while one of them is already known from previous studies (the
Raska River). The species was found in running, moderately hard and very
hard, well-oxygenated, slightly alkaline waters, mainly low in inorganic
nutrients, and in highly variable values of temperature and conductivity.
Despite the long period since its first observation in Serbian rivers, the
species is still known in a small number of localities. The small number of
localities, low relative abundance, and various anthropogenic influences
affecting its habitats have led the species to be recognized as endangered
and strictly protected in Serbia. The intensive development of small
hydropower plants which have emerged in recent years may threaten B.
atropurpurea habitats.
Upgrading fuel potentials of waste biomass via hydrothermal carbonization

Published: October 2021

In recent decades, massive exploitation of fossil fuels caused a growing demand for the production of energies from renewable sources. Hydrochar obtained from waste biomass via hydrothermal carbonization (HTC) possesses good potentials as a biofuel. Therefore, we performed HTC of corn cob, paulownia leaves, and olive pomace at different temperatures (180, 220, and 260oC). The main goal of this study was to comparatively evaluate the influence of HTC conditions on the structure and fuel characteristics of the obtained solids. The results showed that the yields of hydrochar decrease significantly with increasing temperature in all samples. The carbon content and higher heating value increased and reached the highest values in hydrochars obtained at 260?C, while the content of volatile matter decreased. Furthermore, the Van Krevelen diagram reveals that the transformation of feedstock to lignite-like products upon HTC was achieved. In this study, the results showed that processes of dehydration and decarboxylation during HTC provoke intensive biomass transformation and that hydrochars obtained at higher temperatures have significantly enhanced fuel properties and fewer volatiles compared to the feedstock.

In this paper, a class of nonlinear evolution equations with damping arising in fluid dynamics and rheology is studied. The nonlinear term is monotone and possesses a convex potential but exhibits non-standard growth. The appropriate functional framework for such equations is the modularly Museilak–spaces. The existence and uniqueness of a weak solution are proved using an approximation approach by combining an internal approximation with the backward Euler scheme, also a priori error estimate for the temporal semi-discretization is given.

The question of interest for the presented study is the mathematical modeling of wave propagation in dissipative media. The generalized fractional Zener model in the case of dimension d (d=1,2,3) is considered. This work is devoted to the mathematical analysis of such model: existence and uniqueness of the strong and weak solution and energy decay result which guarantees the wave dissipation. The existence of the weak solution is shown using a priori estimates for solutions which are also presented.

Radio-frequency identification (RFID) is a new technology used for identifying and tracking objects or people by radio-frequency waves to facilitate automated traceability and data collection. The RFID system consists of an electronic tag attached to an object, readers, and a middleware. In the latest real applications based on the RFID technology, the deployment of readers has become a central issue for RFID network planning by means of optimizing several objectives such as the coverage of tags, the number of readers, and the readers/tags interferences. In practice, the system is affected by uncertainty and uncontrollable environmental parameters. Therefore, the optimal solutions to the RFID network planning problem can be significantly reduced with uncontrollable variations in some parameters, such as the reader's transmitted power. In this work, we propose a robust multi-objective optimization approach to solve the deployment of RFID readers. In this way, we achieve robust optimal solutions that are insensitive to uncertainties in the optimization parameters.

Forced convection problem of laminar quasi-incompressible boundary layer for the stagnation slip flow at a relatively low Mach number, considering the simultaneous effects of viscous dissipation and pressure work, has been investigated. The system of coupled partial differential equations was first transformed into a system of coupled ordinary differential equations through suitable transformations, which was then solved using Runge–Kutta–Fehlberg fourth-fifth order method. The solution obtained here is much better suited to formulating and solving the variable-property of chemically reacting flows that occur in practice, by taking into account the slip boundary conditions at the gas–wall interface. The effects of the Eckert number and the slip parameter on the heat transfer characteristics are presented graphically and discussed. The numerical results show that the pressure work, viscous dissipation play significant role on the heat transfer and could not be neglected under any circumstance for rarefied gas flows.

Vehicle routing problems are widely available in real world application. In this paper, we tackle the resolution of a specific variant of the problem called in the literature vehicle routing problem with flexible time windows (VRPFlexTW), when the solution has to obey several other constraints, such as the consideration of travel, service, and waiting time together with time-window restrictions. There are proposed two modified versions of the Multi-objective Adaptive Large Neighbourhood Search (MOALNS). The MOALNS approach and its different components are described. Also it is listed a computational comparison between the MOALNS versions and the Ant colony optimiser (ACO) on a few instances of the VRPFlexTW.

Hyper-heuristics are a subclass of high-level research methods that function in a low-level heuristic research space. Their aim objective is to improve the level of generality for solving combinatorial optimization problems using two main components: a methodology for the heuristic selection and a move acceptance criterion, to ensure intensification and diversification [1]. Thus, rather than working directly on the problem's solutions and selecting one of them to proceed to the next step at each stage, hyper-heuristics operates on a low-level heuristic research space. The choice function is one of the hyper-heuristics that have proven their efficiency in solving combinatorial optimization problems [2–4]. At each iteration, the selection of heuristics is dependent on a score calculated by combining three different measures to guarantee both intensification and diversification for the heuristics choice process. The heuristic with the highest score is therefore chosen to be applied to the problem. Therefore, the key to the success of the choice function is to choose the correct weight parameters of its three measures. In this study, we make a state of the art in hyper-heuristic research and propose a new method that automatically controls these weight parameters based on the Boltzmann function. The results obtained from its application on five problem domains are compared with those of the standard, modified choice function proposed by Drake et al. [2,3].

In this paper, a new Blind Source Separation (BSS) method that handles mixtures of noisy independent/dependent sources is introduced. We achieve that by minimizing a criterion that fuses a separating part, based on Kullback–Leibler divergence for either dependent or independent sources, with a regularization part that employs the bilateral total variation (BTV) for the purpose of denoising the observations. The proposed algorithm utilizes a primal-dual algorithm to remove the noise, while a gradient descent method is implemented to retrieve the signal sources. Our algorithm has shown its effectiveness and efficiency and also surpassed the standard existing BSS algorithms.

To guarantee the non-negativity of the conditional variance of the GARCH process, it is sufficient to assume the non-negativity of its parameters. This condition was empirically violated besides rendering the GARCH model more restrictive. It was subsequently relaxed for some GARCH orders by necessary and sufficient constraints. In this paper, we generalized an approach for the QML estimation of the GARCH(p,q) parameters for all orders $p\geq 1$ and $q\geq1$ using a constrained Kalman filter. Such an approach allows a relaxed QML estimation of the GARCH without the need to identify and/or apply the relaxed constraints to the parameters. The performance of our method is demonstrated through Monte Carlo simulations and empirical applications to real data.

The phenomenon of mixed convection heat transfer in a homogeneous mixture is deliberated thoroughly in this study for cooper-water nanofluids flowing inside a lid-driven square cavity. By adopting the Oberbeck-Boussinesq approximation and using the single-phase nanofluid model, the governing partial differential equations modeling the present flow are stated mathematically based on the Navier--Stokes and thermal balance formulations, where the important features of the scrutinized medium are presumed to remain constant at the cold temperature. Note here that the density quantity in the buoyancy body force is a linear temperature-dependent function. The characteristic quantities are computed realistically via the commonly used phenomenological laws and the more accurate experimental correlations. A feasible non-dimensionalization procedure has been employed to derive the dimensionless conservation equations. The resulting nonlinear differential equations are solved numerically for realistic boundary conditions by employing the fourth-order compact finite-difference method (FOCFDM). After performing extensive validations with the previously published findings, the dynamical and thermal features of the studied convective nanofluid flow are revealed to be in good agreement for sundry values of the involved physical parameters. Besides, the present numerical outcomes are discussed graphically and tabularly with the help of streamlines, isotherms, velocity fields, temperature distributions, and local heat transfer rate profiles.
