Central and regional governments must innovate in communication technology in the fourth industrial revolution. This study aims to identify and analyze the digital communication transformation in the government of Sukabumi City through the innovative use of communication technology. This study uses the Adaptive Structuring Theory (AST) theory, which studies the adaptation of new information technology within an organization. The methodology uses a qualitative approach with primary data collection through interviews with Diskominfo and the Sukabumi City Kelurahan. Meanwhile, the FGD was conducted with the community and sub-district staff of three sub-districts in Sukabumi City, namely Cisarua, Subang Jaya, and Cikole sub-districts. The results of this study accelerated the digital communication transformation in Sukabumi City’s electronic-based government system services (SPBE). Adaptation of technology in integrated organizations impacts government systems, civil servants, business actors, and the community. Sukabumi City’s government is transforming communication in public services, complaint applications, and population administration applications to become government and community media in communicating. Meanwhile, business actors are facilitated by the city government in implementing licensing and digital marketing communications presented through government social media, which helps increase consumer engagement.
Between Human and Virtual Idol: Fans Reception Analysis of Digital Alter Ego Concept
Authors: Nuranda Damar Rizky , Purwaningtyas Mashita Phitaloka Fandia
Published: June 2023

The emergence of K-pop idol group Aespa has changed the landscape of K-pop fan culture since the group introduced the concept of a digital alter ego in the form of digital “ae” members. This research aims to understand how Indonesian fans construct the meanings of the digital alter ego concept carried by Aespa. This research is conducted by the reception analysis method. Informants consisted of four Aespa’s fans, each with distinct experience as K-pop fans. The main findings in this research revolve around the different reading positions held by informants, as affected by the distinct framework of knowledge, relations of consumption, and technical infrastructure surrounding their cultural practices as K-pop fans. Aespa’s digital alter ego could be seen in three ways: as another version of the self, a dishonest self-representation, and a polished version of the self. Through these differences, it can be concluded that fans’ construction of meanings cannot be reviewed through a deterministic approach but through a socio-cultural approach instead.

Published: June 2023

The digital era has brought a massive impact on business development in Indonesia., However, the Covid-19 pandemic has crushed almost all small and medium enterprises (SMEs), and they are currently trying to stand and rise again in the post-pandemic. This study aims to identify the business development process in SMEs by using digital methods carried out by youth groups in pandemic situations from interactional communication perspectives. The concept used in this study is an interactional communication model with the element of individual meaning toward the social environment and individual field of experience. This research method is descriptive qualitative through focused group discussion (FGD). The result found that from the interactional communication process, the meaning interpreted by the group member toward their social environment was the identification of a number of problems faced by the SME owner. Other than that, there was also the meaning-making about building enterprises by utilizing digital media for marketing, especially in creating a platform for content management. Groupmembers’ different field of experience has brought opportunities to respond to eachother’s problem. There are also opportunities to create a new network and collaboration in searching for a solution to build a business with a digital marketing method.
Andy’s ‘T-pin’Crown and root aligning auxillary
Authors: Deshmukh Sayali S , Ambekar Anand , Kangane Suresh , Chate Jyotsna H
Published: June 2023

Orthodontists strive for accurate bracket positioning as it helps in achieving an ideal occlusion more easily. For accurate bracket positioning in direct bonding, various hand-held dental instruments are used. Instruments such as, the Boone and Dougherty gauges, MBT gauges, A-KAM and various other modifications, are used for accurate positioning of brackets. Sometimes the bracket can easily slip when the instrument is removed. So, position adjustments are difficult with such an instrument. Indirect bonding is an easy solution, but it is time-consuming and there is no precise repositioning of brackets that fall off and it does not provide proper root paralleling. This led us to develop an auxiliary which can be used for crown and root paralleling or aligning, horizontal, vertical and axial positioning of bracket (Pre-Treatment assessment) during direct bonding. This will avoid the step of repositioning of the bracket at mid or end of the treatment.

Published: June 2023

The current study aims to provide quantitative and qualitative information about the prevalence of dental malocclusions among dental students of Kabul University of Medical Sciences (KUMS) in the orthodontics department of Ali Abad Teaching Dental Clinic that evaluates the relationship of malocclusion between gender and the major causes of malocclusion in society among genders and the tendency of the community toward the treatment of dentoalveolar anomalies.

This study was a cross-sectional survey that was done randomly among 133 students, 68 male (51.12%) and 65 female (48.87%), in an age range of 18–25 years old at Kabul University of Medical Sciences, Ali Abad teaching dental clinic faculty of dentistry.

show the dental malocclusion classes due to “angle" classification in females in Class I (53.48%), Class II (21.4%), and Class III (23.07%), while in males in Class I (48.33%), Class II (6.66%), and Class III (43.33%). The prevalence rate of crowding was 33% in males and 43% in females. It has been studied and analyzed separately that the most common oral problems in females were dental caries (53.84%). According to our survey (65 female participants), no one had periodontitis, while in males, plaque was at a rate of 28.97%, and the least common was gingivitis (6%), respectively.

The occurrence of dental trauma in boys and heredity in girls may be the most important factors for dental malocclusion. Girls were more interested in orthodontic treatments, which may be because they pay more attention to beauty than boys. Moreover, crowding had the highest rate among participants, followed by deep, open bites and edge-to-edge bites.

Authors: Shetty Akhil , Sadik Jaffer
Published: June 2023

The aim of this study was to assess the relationship between the cranial base, mandible, and hyoid bone in Class II skeletal individuals.

The retrospective study included lateral cephalograms of 40 Skeletal Class II subjects divided into maxillary prognathism (n=20) and mandibular retrognathism(n=20) based on Burstone’s N⊥A and N⊥B values. The angular measurements using 10 variables were used to determine the relationship between the cranial base, mandible, and hyoid bone in Class II subjects. Statistical analyses were performed using IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp. An Independent t-test was used to compare the two groups and a p-value less than 0.05 was considered statistically significant. Post-Hoc Bonferroni was applied to examine any changes among any two groups that were found to differ statistically.

NSAr, C3HyD, SArHy, and NSHy angles were measured in both groups. NSAr and NSHy angles showed significance between the two groups of skeletal class II whose p-value <0.05 whereas C3HyD and SArHy angles did not show any significance.

The condylar position was anterior in maxillary prognathism compared to mandibular retrognathism of Skeletal Class II. The hyoid bone was positioned forward and upward in maxillary prognathism individuals and downward and backward in mandibular retrognathism individuals belonging to skeletal class II.

To conduct a prospective randomized study comparing the efficiency of four different ligation systems (ELL,SSL,LL,PSL) over the duration of mandibular crowding alleviation.

The study was conducted in Department of Orthodontics and Dentofacial Orthopaedics, Noorul Islam College of Dental Sciences, Neyyattinkara, Trivandrum. The present study evaluated the variations in alignment efficiency of four different ligation systems over the duration of mandibular crowding alleviation in patients during mandibular crowding alleviation. Eighty patients fulfilling the inclusion criteria were selected and equally divided into four groups- Elastomeric ligation (ELL), Stainless steel Ligation (SSL)- active and passive , Leone slide Ligatures (LL).

: The mean treatment time for alignment for passive self ligating group (102 days) followed by leone group (128 days), stainless steel (176 days) and elastomeric (224 days) group. Thus the study showed no significant difference in the clinical performance between coventional, self ligating, while PSL performed significantly superior to other groups. From the above equation, during initial phase of orthodontic treatment.self-ligating brackets were more efficient than conventional brackets in anterior alignment, passive space closure, and mandibular incisal inclination.

Published: June 2023

The incidence of ectopically erupting canine is quite common, reasons are multifactorial, but usually it's the lack of space which happens due to mesial drift of the posterior teeth or the inherent discrepancy between arch length and tooth size discrepancy. If it's the former, distalization is one of the Go-to treatment modality one can opt for provided the nose and lip relation is optimum and does not warrant for extraction. If it's the latter then extraction remains the only choice. This case report discusses an innovative way of aligning a highly placed canine without taxing the anchorage in all 3 planes with help of Skeletal anchorage and Loop mechanics while also correcting the inclinations and gummy smile without hindering nose-lip relation to a certain extent and also tackling the common problem of anatomically short upper lip.

10./16. Asırda Yazılmış Bir Makâlât Eseri: Fırḳa-i Nâciye Nasîrüddîn et-Tûsî ve Devvânî Üzerinden Hak Mezhebin Tespit Yöntemine Dair Polemikler
Authors: IŞILAK Halil
Published: June 2023

Bu çalışmada 982/1574 yılında İmâmiyye Şîası'na mensup bir âlim tarafından Farsça kaleme alınmış Fırḳa-i Nâciye isimli makâlât eserindeki fırka tasnifleri ele alınmaktadır. Merkez-i İḥyâʾi Mîras̱-ı İslâmî Kütüphanesi’nde yer alan ve bildiğimiz kadarıyla başka nüshası bulunmayan bu risalede yetmiş üç fırka tasnifi üzerinden İmâmiyye Şîası'nın fırka-i nâciye olduğu ispatlanmaya çalışılmaktadır. Yazar; şeytanın ortaya attığı yedi şüphe, ümmetin ihtilaf etmesine sebep olan ilk olaylar ve mezhepler hakkındaki genel bilgileri el-Milel ve’n-niḥal’den, fırka tasniflerini Şerḥu’l-Mevâḳıf’dan özetlemiş, fakat bu metinlerdeki verileri Şiî anlayış istikametinde yeniden kurgulamıştır. Öte yandan bu risalenin yazılmasındaki asıl sebep fırka tasnifinden ziyade Celâlüddîn ed-Devvânî’nin iddialarına cevap üretmektir. Nasîrüddîn et-Tûsî, fırka-i nâciyenin tespiti noktasında “akaid/usûl konularında bütün mezheplerden farklılaşmak” şeklinde bir yöntem belirlemiş; İmâmiyye Şîası'nın akaid konularının tamamında diğer mezheplerden farklılaştığını ve bundan dolayı da fırka-i nâciye olduğunu iddia etmiştir. Devvânî ise İmâmiyye’nin sadece akaid konusu olmayan imamet anlayışıyla diğer mezheplerden ayrıştığını ve bunun dışındaki akîde esaslarında genellikle Mu‘tezile ile muvafık olduğunu belirtmiş ve böylelikle Tûsî’nin iddiasının temelsiz olduğunu ileri sürmüştür. Bu noktada söz konusu yönteme göre Eş‘arîliğin fırka-i nâciye olmaya daha layık olduğunu, çünkü bu mezhebin akîdeyle ilişkili konularda bütün mezheplerden farklılaştığını ifade etmiştir. Fırḳa-i Nâciye yazarı, Devvânî’nin iddiasının aksine imametin dinin en önemli esaslarından birisi olduğunu belirtmiş ve ayrıca İmâmiyye’nin imamet dışında başka konularda da diğer mezheplerden ayrıştığını iddia etmiştir. Fakat bu iddiasını temellendirmede noktasında yeterli veri sunamamıştır.

Published: June 2023

O reconhecimento da necessidade de ações para fazer frente aos impactos das mudanças climáticas, de diversidade e regras de compliance leva a um aumento dos investimentos pelas empresas que adotam práticas de sustentabilidade que vêm se tornando relevantes para as decisões de investidores. No Brasil, a percepção sobre o valor da adoção das práticas de ESG é mais recente e vem crescendo, havendo o reconhecimento de que o desenvolvimento econômico deve ocorrer com avanço sustentável no país. Este estudo verifica se a adoção de práticas de sustentabilidade acarreta numa redução do custo de capital de 96 empresas – não financeiras – brasileiras, de capital aberto, e com informações de pontuação ESG de, ao menos, 3 anos no período de 2016 a 2020 utilizando regressões múltiplas lineares por pooled ou painel. Verifica-se a existência de uma relação negativa entre o componente ambiental e o custo do capital de terceiros que confirma uma preocupação crescente dos países sobre as questões ambientais. Porém com a não ratificação da hipótese de redução de custo de capital próprio, indica-se que os credores possuem maior sensibilidade às práticas ambientais das empresas que seus acionistas. Dessa forma, diferentemente dos países desenvolvidos, empresas e investidores brasileiros ainda não conseguem perceber os benefícios financeiros advindos da adoção de práticas de sustentabilidade, apontando oportunidades para tais investimentos.

The paper presents results of studying the possibility of synthesizing aqueous dispersions of the vanadium (V) oxide nanoparticles that retain aggregative stability for a long period. The experiments performed resulted in obtaining tubular nanoparticles of the vanadium pentoxide (V2O5) 50 µm long and 5--10 nm in diameter. Wall thickness of the obtained tubes was 1.1 nm. It was experimentally established that type of the acid used was not affecting the resulting nanoparticles size, but was significantly effecting the shelf life. To increase the nanoparticles optimal shelf life, it is proposed to use the hydrochloric acid solutions as the peptizing agent. This method made it possible not only to increase the system stability, but also to raise the nanoparticles concentration up to 1 % of the mass. In the framework of experiments on studying the obtained particles surface characteristics, it was found that nanoparticles in the range of pH = 3.0--4.2 were negatively charged, and aggregation stability was mainly determined by the electrostatic factor. The proposed chemical technology could be used in industrial production of the vanadium pentoxide nanoparticles in various industries

Published: June 2023

The first and second laws of thermodynamics analysis used to show the rate of energy and exergy as a performance of SI-PFI engine with the variation of fuel ignition between 10 and 26 BTDC (before top dead Centre) at interval 4 BTDC. The engine was performed on eight levels of speed in intervals 2000--8000 RPM (increment of 1000 RPM) with pure bioethanol fuel (E100) and 13:1 of compression ratio. The effect of fuel ignition on energy and exergy analysis of E100 fuel will be compared with E0 as reference fuel that performed in 11:1 of compression ratio and 10 BTDC. The results show that the maximum efficiency of energy and exergy for the E100 are 46.59 and 41.90 % at 18 BTDC and 6000 RPM. Meanwhile, the maximum efficiency of energy and exergy for E0 were 43.33 and 31.76 % at 5000 RPM. Moreover, the minimum BSFC for the E100 is 0.2867 kg/(kW•h) at 6000 RPM and 18 BTDC while for the E0 is 0.1960 kg/(kW•h) at 5000 RPM. These results indicate that E100 is more effectivein transferring heat into useful work although it is 30 % more wasteful than E0

Published: June 2023

Carbon nanofibers are currently used in many applications including electrochemical power sources, particularly, fuel cells. Their properties are highly dependent on the micro- and mesoporous structure. Here we provide a porosimetric analysis of the polyacrylonitrile-based electrospun composite Zr- and Ni-containing carbon nanofiber mats by N2 and CO2 adsorption methods for the first time. It was found that pyrolysis temperature affects specific surface area and volume: the values increase for the sample pyrolyzed at 900 °C compared with the initial stabilized nanofibers (300 °C, air) according to the Dubinin --- Radushkevich, non-local density functional theory (NLDFT) and grand canonical Monte-Carlo methods (GCMC). For higher pyrolysis temperatures (1000 and 1200 °C), the porosimetric parameters decrease compared with the one pyrolyzed at 900 °C. According to the NLDFT and GCMC pore size distribution, the difference for pyrolyzed samples is mostly related to a sharp decrease in the specific surface area for pores with a size of ~ 0.5 nm and an increase for pores at 0.55--0.8 nm compared with the initial stabilized sample. The study demonstrates a way to adjust porosimetric parameters depending on the pyrolysis conditions of the nanofiber mats, since it can improve characteristics of such type of carbon materials in electrochemical devices

The paper proposes substantiation of dependence of dielectric permittivity, polariton dispersion and light group velocity in the sodium uranyl acetate on the wavelength. Many bands were found in the uranyl compounds transmission and absorption spectra. It was indicated that the polariton waves group velocity was decreasing anomalously in vicinity of the resonant absorption frequencies, i.e., the light was effectively stopped. This led to abnormal increase in the efficiency between the light interaction processes and the matter. Optical properties of the one-dimensional photonic crystal film formed by electrochemical etching of aluminum foil were studied. Experimental data on the transmission and reflection spectra in the region of first, second and third stop bands of the anode photonic aluminum oxide crystal were compared with theoretical dependence obtained from the known dispersion relation. Refractive indices of the first and second layers of various thin photonic crystal films, structure period and effective refractive index of the structures were theoretically calculated. Possibility of controlling position of the stop bands of one-dimensional photonic crystals in accordance with the Wulff --- Bragg’s relation was established. The studied photonic crystals could be used in experimental setups to register the light combined scattering spectra of dielectric media in the low-frequencies region
Luminescence Intensity ELF Oscillations from a Polymer Membrane in the Aqueous Salt Solutions

Published: June 2023

The paper studies luminescence from the Nafion polymer membrane surface at its swelling in the isotonic aqueous solutions and bi-distilled water using the experimental photo luminescent spectroscopy. Liquid samples were preliminarily treated with the electric pulses with duration of 1 µs and amplitude of 0.1 V using antenna in the form of a flat capacitor. Experiments in photo luminescent spectroscopy were carried out 20 min after the electric pulse treatment. Typical luminescence intensity dependence on the membrane swelling time could be represented as the exponentially decreasing function. Characteristic decay time of the corresponding functions and stationary level of the membrane luminescence intensity depend on the electrical pulses repetition rate. The obtained dependencies could well be reproduced. However, dependence of the luminescence intensity at certain pulse repetition rates appears to be a random function, and the reproducibility is missing. It could be assumed that these stochastic effects are associated with exposure to random external force of the electromagnetic nature acting on the polymer membrane during swelling. Low-frequency pulsations of neutron stars or white dwarfs are the source of this random force according to the authors of the work. This effect is associated with depolarization during the low-frequency electromagnetic field scattering caused by the neutron stars pulsation. Depolarization effect arises due to scattering on long-living anisotropic clusters of nano-bubbles, which, in turn, are becoming anisotropic in the external field of a flat capacitor. Depolarized scattered radiation causes stochastic oscillations of the polymer fibers unwound into the bulk liquid. In this case, luminescence should also acquire the stochastic character taking into account the effect of resonant luminescence energy transfer from a donor to the luminescence acceptor
Quasi-Harmonic Bending Waves Evolution in a Beam Lying on the Generalized Nonlinear-Elastic Foundation and Possibility of their Transformation into a Sequence of Wave Packets
Authors: Erofeev V.I. , Morozov A.N. , Tsarev I.S.
Published: June 2023

The paper considers dynamic behavior of a track structure, which is a beam performing bending vibrations and lying on the elastic foundation. In this case, a generalized base model is selected that contains two independent bed coefficients: stiffness for tensile (compressive) and shear deformations. Such a model takes into account the soil distributive ability, i.e., its property to settle not only under the loaded area and the foundation, but also in its vicinity. In addition,to describe the foundation stiffness nonlinear properties, the model assumed dependence on the transverse midline beam and its gradient displacement. Results analysis of the wave processes in the beam showed that, since bending waves had strong dispersion, solution to the problem in the presence of weak nonlinearity was close to solution of a linear problem, and it could be represented as a set of quasi-harmonics. Using the Lighthill criterion, conditions modulation instability manifestation (self-modulation) of the quasi-harmonic waves, which led to their spatial localization and division into separate wave packets, were studied. Analytical expressions were found that described the wave packets shapes. Dependences connecting the amplitude and the wave packet width with the elastic foundation rigidity were analyzed

Pituitary apoplexy is a rare acute condition that can be caused by hemorrhage into the pituitary adenoma or its infarction. This is accompanied by severe headache, nausea, vomiting, photophobia, visual and oculomotor disorders, loss of consciousness, and can also lead to a decrease in the production of a number of hormones by the pituitary gland, i.e. hypopituitarism. We present a clinical case of a 42-year female patient with previously undiagnosed acromegaly and papillary thyroid cancer. The reason for the examination was clinical symptoms of pituitary apoplexy. Right hemithyroidectomy with central and lateral lymphadenectomy was performed for her papillary thyroid cancer, followed by radioactive iodine therapy due to an increased risk of cancer progression. Hemorrhage into the pituitary adenoma in this patient has led to panhypopituitarism and remission of acromegaly. Insulin-like growth factor 1 and growth hormone levels during oral glucose tolerance test were within the reference values, which made the diagnosis of acromegaly challenging.

Após a promulgação da Lei 13.257 (2016), cunhada como Marco Legal da Primeira Infância, concebeu-se a possibilidade de conversão da prisão preventiva em prisão domiciliar para mulheres grávidas ou com filhos de até 12 anos incompletos. Destarte, este artigo teve como objetivo analisar, à luz da Criminologia negra e feminista, de que maneira o Judiciário paraibano tem se pronunciado a respeito da concessão da medida cautelar domiciliar para estas mulheres. Para tanto, a metodologia adotada foi a pesquisa documental, de abordagem qualitativa, sendo analisadas as decisões em sede de habeas corpus da Câmara Criminal do Tribunal de Justiça da Paraíba entre 2018 e 2019. Foram examinados 57 julgados que negaram o pedido de conversão da preventiva em domiciliar, sendo analisado o discurso jurídico em torno da mulher que teria cometido o delito. Constatou-se que a fundamentação utilizada se assenta, com frequência, em um discurso moral sobre a mulher. Ainda, vislumbra-se que a medida cautelar domiciliar é necessária e importante como política desencarceradora e para a manutenção dos vínculos maternos, mas que se trata de mais uma medida privativa de liberdade. Portanto, entende-se que se deve ter como horizonte uma sociedade em que nenhuma mulher precise estar encarcerada.

Published: June 2023

The main aim of the study was to explore the feature selection process of online web data prior to unsupervised machine learning models. At the time of writing, no such literature could be found reporting the use of feature selection in this context. Feature selection was determined by inspecting the variability and association between features. The variability of numeric features were quantified using the variance, mean absolute difference and dispersion ratio metrics whilst the coefficient of unalikeability was employed for categorical features. To quantify association, correlation matrices were used for numeric features, chi-squared independence tests between categorical features and box-and-whisker plots between mixed features. The main findings showed the variance, mean absolute difference, dispersion ratio and coefficient of unalikeability metrics have successfully highlighted features with very low variability within the observed data. Whilst the correlation matrix, chi-squared test for independence and box-and-whisker plots highlighted possible redundancy, natural relationships and insightful relationships between the features thereby suggesting features to be considered for omission prior to unsupervised modelling. The proposed methods and findings can be applied to various other applications of feature selection and exploration.

In this paper, we study generalized stress-strength model for generalized logistic distribution. The maximum likelihood estimator of this quantity is obtained and then a confidence interval is presented for it. Bayesian and bootstrap methods are also applied for the recommended model. A Markov Chain Monte Carlo (MCMC) simulation study for assessing the estimation methods is performed via the Metropolis-Hastings algorithm in each step of Gibbs algorithm. An application to real data set is addressed.

Regression models are very useful in describing and predicting real world phenomena. The Logistic regression is an extremely robust and flexible method for dichotomous classification prediction. This model is a classification model rather than regression model. When the number of predictors in regression models is high, data analysis is difficult. Dimension reduction has become one of the most important issues in regression analysis because of its importance in dealing with problems with high-dimensional data. In this paper, the methods of diminishing the dimension of variables in logistic regression, which include the estimation of central subspace based on the inverse regression, the likelihood acquisition method and principal component analysis are considered. Using a real data associated with the dental problems the Logistic regression is fitted and the correct classification of the data computed. At the end, The simulation study is presented to compare the sufficient dimension reduction methods with each other. In the simulation, MATLAB software is used and the Programs are attached at the end of the article in appendix.

Authors: Muhammed Hiba
Published: June 2023

In this paper, the likelihood function under progressive Type II censoring is generalized for Marshal-Olkin bivariate class of distributions and applied it on the bivariate Dagum distribution. Maximum likelihood estimation is considered for the model unknown parameters. Asymptotic and bootstrap confidence intervals for the unknown parameters are evaluated under progressive Type II censoring. Bayesian estimation is also considered in both complete and progressive Type II censored samples; moreover, the Bayes estimators are obtained explicitly with respect to square error loss function in both cases.

Authors: Othman Sameera Abdulsalam , Haithem Taha Mohammed Ali
Published: June 2023

The aim of this paper is to select an appropriate ARIMA model for the time series after transforming the original responses. Box-Cox and Yeo-Johnson power transformation models were used on the response variables of two time series datasets of average temperatures and then diagnosed and built the appropriate ARIMA models for each time-series. The authors treat the results of the model fitting as a package in an attempt to decide and choose the best model by diagnosing the effect of the data transformation on the response normality, significant of estimated model parameters, forecastability and the behavior of the residuals. The authors conclude that the Yeo-Johnson model was more flexible in smoothing the data and contributedto accessing a simple model with good forecastability.
A Primal-Dual Interior-Point Algorithm Based on a Kernel Function with a New Barrier Term
Authors: Guerdouh Safa , Chikouche Wided , Touil Imene
Published: June 2023

In this paper, we propose a path-following interior-point method (IPM) for solving linear optimization (LO) problems based on a new kernel function (KF). The latter differs from other KFs in having an exponential-hyperbolic barrier term that belongs to the hyperbolic type, recently developed by I. Touil and W. Chikouche \cite{filomat2021,acta2022}. The complexity analysis for large-update primal-dual IPMs based on this KF yields an $\mathcal{O}\left( \sqrt{n}\log^2n\log \frac{n}{\epsilon }\right)$ iteration bound which improves the classical iteration bound. For small-update methods, the proposed algorithm enjoys the favorable iteration bound, namely, $\mathcal{O}\left( \sqrt{n}\log \frac{n}{\epsilon }\right)$. We back up these results with some preliminary numerical tests which show that our algorithm outperformed other algorithms with better theoretical convergence complexity. To our knowledge, this is the first feasible primal-dual interior-point algorithm based on an exponential-hyperbolic KF.

Authors: Refaie Mohamed , Mahran Hisham Abdeltawab
Published: June 2023

In this work, we introduce a new G family with two-parameter called the compound reversed Rayleigh-G family. Several relevant mathematical and statistical properties are derived and analyzed. The new density can be heavy tail and right skewed with one peak, symmetric density, simple right skewed density with one peak, asymmetric right skewed with one peak and a heavy tail and right skewed with no peak. The new hazard function can be "upsidedown-constant", "constant", "increasing-constant", "revised J shape", "upside-down", "J shape" and "increasing". Many bivariate types have been also derived via di¤erent common copulas. The estimation of the model parameters is performed by maximum likelihood method. The usefulness and ‡exibility of the new family is illustrated by means of two real data sets.

We analyze the chances of winning a tournament under the assumption that the probabilities of winning individual matches follow Bradley-Terry model [2]. We present an exact solution and show a few examples of its use. The examples are from California volleyball tournaments, the round of sixteen in the World Cup and the Champions League, the group stage of the Association of Tennis Professionals tournament, and the volleyball SuperLega in Italy.

The computational complexity of the solution grows exponentially fastwith the number of teams and we seek approximations via multivariate Gaussian laws.

Authors: Amiri Ehsan , Mosallanejad Ahmad , Sheikhahmadi Amir
Published: June 2023

Image forgery detection is a new challenge. One type of image forgery is a copy-move forgery. In this method, part of the image is copied and placed at the most similar point. Given the existing algorithms and processing software, identifying forgery areas is difficult and has created challenges in various applications. The proposed method based on the Equilibrium Optimization Algorithm (EOA) helps image forgery detection by finding forgery areas. The proposed method includes feature detection, image segmentation, and detection of forgery areas using the EOA algorithm. In the first step, the image converts to a grayscale. Then, with the help of a discrete cosine transform (DCT) algorithm, it is taken to the signal domain. With the help of discrete wavelet transform (DWT), its appropriate properties are introduced. In the next step, the image is divided into blocks of equal size. Then the similarity search is performed with the help of an equilibrium optimization algorithm and a suitable proportion function. Copy-move forgery detection using the Equilibrium Optimization Algorithm (CMFDEOA) can find areas of forgery with an accuracy of about 86.21% for the IMD data set and about 83.98% for the MICC-F600 data set.
Grey Median Problem and Vertex Optimality
Authors: Fathali Jafar
Published: June 2023

The median problem is a basic model in location theory and transportation sciences. This problem deals with locating a facility on a network, to minimize the sum of weighted distances between the facility and the vertices of the network. In this paper, the cases that weights of vertices, edge lengths or both of them are grey numbers, are considered. For all these cases, we show that the set of vertices of network contains a solution of the median problem. This property is called vertex optimality. Median problem with grey parameters and its properties are first considered in this paper.

Published: June 2023

Over the years, the boom of technology has caused the accumulation of a large amount of data, famously known as big data, in every field of life. Traditional methods have failed to analyse such a huge pile of data due to outdated techniques. In recent times, the use of photovoltaic systems has risen worldwide. The arena Photovoltaic (PV) system has witnessed the same unprecedented expansion of data owing to the associated monitoring systems. However, the faults created within the PV system cannot be detected, classified, or predicted by using conventional techniques. This necessitates the use of modern techniques such as Machine Learning. Its powerful algorithms, such as artificial neural networks (ANN), help in the accurate detection and classification of faults in the PV system. This review paper introduces and evaluates the applications of Machine Learning (ML) algorithms in PV fault detection. It provides a brief overview of Machine Learning and its concepts along with various widely used ML algorithms. This review various peer-reviewed studies to investigate various models of ML algorithms in the PV system with the main focus on its fault detection accuracy and efficiency.

Published: June 2023

In this work, we suggest a variety of optimal daily diets for people with diabetes in Morocco. To this end, we model the foods glycemic load in term of triangular fuzzy numbers. Then, we model the problem of daily diet in term of fuzzy quadratic optimization programming. To transform this model into a line model, we use a very performance ranking function. To solve the obtained model, we call particles swarm algorithm due to its performance and simplicity. Various experiments were carried out on the basis of feeds available on the Moroccan market and for different sizes of the PSO swarm. The experimental results show that our system proposes optimal diets with a reasonable glycemic load between, acceptable favorable gaps and unfavorable nutrients excesses. We show how to combine the proposed diets to obtain a balanced weekly regime.

Buildings frequently utilize radiant heating floors because they offer benefits including effective use of space and homogeneous temperature distribution, which results in increased thermal comfort. The present work aims to investigate the perfect use of floor heating systems analytically and numerically with improved thermal performance to prove their efffficiency in various African climates. The evaluation depends on the functional parameters of the heating system and particularly focuses on floor surface temperature to acquire the desired heat flux and the perfect supply water temperature. According to results, It is desirable to use floor coverings with low thermal resistance and should not exceed R = 0.15 m2 . K/W since it has considerable influence on the thermal efffficiency of the underfloor heating components. The pipe diameter is suggested to be about 20 mm. By comparing pipe spacings of 15 mm and 30 mm, the difference in supply water temperature is approximately 7.4 C. The smaller the pipe spacing, the more energy it delivers and makes the floor much warmer while reducing heating time. Regarding the effect of pipe materials, PE-X is chosen for this study because of its low cost and resistance to corrosion and scaling. As the influence of these studied parameters on floor heating is remarkable, there is also the impact of the ambient temperature of each city on the floor heating efffficiency. The proposed model can be applied and considered potentially beneficial and helpful to the control, and design of floor heating systems, and choosing the right heating source.
