This paper presents the results of the geometric nonlinear analysis of composite shell subjected to static load by using an edge-based smoothed finite elements (ES) and the mixed interpolation of tensorial components technique (MITC). The shell is decrete by three-node triangular elements inwhich the stiffness matrices are obtained by using the strain smoothing technique over the smoothing domains formed by two adjacent triangular elements sharing an edge. Equilibrium equation system of the composite shell is formed by the first order shear deformation theory with the geometrical nonlinearity in von Kármán strains. Numerical results show good accuracy and convergence as compared to other existing methods in the literature when employed to analyze the nonlinear static composite shells.

Authors:   Le Quy Don Technical University, Dao Van Hiep
Published: May 2023

In the present study, Taguchi Method (TM) is applied to determine the optimum Ant Colony Optimization (ACO) parameters. The Tool Path Optimization (TPO) for drilling a hole pattern on the Printed Circuit Board (PCB) with 220 holes was examined as a case study. Experimental verification shows that, with the optimal ACO parameters the tool path length is reduced about 2 times and the convergence rate is significantly approved against their average values in the initial data. This setting variant is also confirmed to be actually the best in comparison with available ones. This allows to reduce not only time for machining but also the one for program execution.

Abstract: This research presents an important topic in syntactical studies. It reveals a mysterious aspect of Yemeni AL- Haydara objection, which is the his objection to the grammarians on waqf. I presented the text of AL- Haydara objection, and I discussed the content of his objection through the books of the old grammarians and the modernists, then I choose the opinion that I think is right. The research has been in two parts: the first part is Al- Haydara’s objection to the grammarians on waqf with Rom, (Ishmam) Sound between those of damma and kasra and Reduplication. And the second parts is Al- Haydara’s objection to the grammarians on waqf with transfer. Then I appended the research with a conclusion in which it recorded the results of the research. الملخص: يعرض هذا البحث موضوعاً مهماً في الدراسات النحوية؛ إذ يهدف إلى الكشف عن جانب غامض من جهد الحيدرة اليمني( )، وهو اعتراضاته على النحاة في الوقف. وقد اعتمد البحث على المنهج الوصفي التحليلي في تحليل نص اعتراض الحيدرة على النحاة ومناقشته من خلال كتب النحاة القدامى والمحدثين. وقد اشتمل البحث على محورين، هما: المحور الأول: اعتراضات الحيدرة على النحاة في الوقف بالرَّوْم والإشمام والتضعيف، والمحور الثاني: اعتراض الحيدرة على النحاة في الوقف بالنقل. وتوصل البحث إلى أن الرَّوْم يأتي في المرفوع والمجرور والمنصوب؛ لأن الرَّوْم لا يعني إخفاء الحركة تماماً كما فسره القراء والحيدرة، وإنما هو صويت ضعيف يتبع الحرف تنبيهاً للحركة، بمعنى أن الحركة لم تسقط جميعها، بل ينطق ببعضها، وهذا يضعف ما ذهب إليه الحيدرة المتابع للقراء بمنعهم الرَّوْم في المنصوب، فهم اعتمدوا في ذلك على مصدر وحيد من مصادر السماع وهو القراءات القرآنية، في حين أن النحاة اعتمدوا على ما جاء عن العرب، فهو الأكثر في كلامهم. كما أن الوقف بالنقل جائز عند العرب؛ لأنهم استعملوه في الشعر والنثر، وهذا يضعف حكم الحيدرة على استعمال العامة للوقف بالنقل بأنه ضعيف جداً ؛ لأن حكمه مبني على أقوى المذاهب في الوقف وليس على الاستعمال. وقد أوصى الباحث بـضرورة الاهتمام بالفكر النحوي عند نحاة اليمن، لا سيما في عصـر الحيدرة، والاهتمام بعلماء اللغة والنحو في اليمن، وعلى الجامعات اليمنية الاهتمام بالتراث النحوي اليمني وإحيائه، وإبراز علماء اللغة والنحو في الدراسات اللغوية الحديثة، ورفع مكانتهم. كما يقترح الباحث إجراء دراسة مستفيضة حول الفكر النحوي عند الحيدرة اليمني من خلال كتابه كشف المشكل في النحو، ودراسة اللغات أو اللهجات في (كشف المشكل في النحو) للحيدرة اليمني في ضوء نظريات علم اللغة الحديث (صوتياً- صرفياً- نحوياً- تركيبياً).

No cabe entender la filosofía como una mera rapsodia de opiniones, ni de comentarios ad hoc, ni de retóricas solemnes... por más que puedan ser originales o ingeniosos. Los conceptos filosóficos —al igual que los términos de la ciencia o del propio lenguaje ordinario— están trabados, forman un sistema y sólo cuando se ha controlado en mayor o menor medida un territorio de conceptos e ideas, es posible confrontar ese pensamiento con otros. Incluso, a veces, es el criterio mismo de «sistematización» la clave de una filosofía. Porque una filosofía no sólo puede ser ejercida de hecho como un sistema, sino que puede apelar a cierta coherencia y completud, representándose a sí misma como tal sistema. Uno de los sistemas filosóficos más interesantes en el panorama filosófico español es el de Eugenio Trías, cuya obra, La edad del espíritu, articula la relación entre el Tiempo y el Conocimiento.
Dawg Fight in the Moonlight
Authors: McInnis Tatiana D.
Published: May 2023

This chapter argues that Dawg Fight(2015) and Moonlight(2017) thematize how men who live in low-income Black neighborhoods develop an ethic around their masculinity that prioritizes a dearth of vulnerability and impenetrability that is often coupled with violence. The chapter links this ethic of masculinity to a toxic combination of limited economic opportunities and the entrapment of poverty in a diverse, but still white supremacist culture.
A Novel Identity-Based Privacy-Preserving Anonymous Authentication Scheme for Vehicle-to-Vehicle Communication
Authors: Genc Yasin , Korkuc Cagatay , Aytas Nilay , Afacan Erkan , Sazli Murat H. , Yazgan Erdem
Published: May 2023

This paper proposes a novel bilinear pairing-free identity-based privacy-preserving anonymous authentication scheme for vehicle-to-vehicle (V2V) communication, called “NIBPA”. Today, vehicular ad hoc networks (VANETs) offer important solutions for traffic safety and efficiency. However, VANETs are vulnerable to cyberattacks due to their use of wireless communication. Therefore, authentication schemes are used to solve security and privacy issues in VANETs. The NIBPA satisfies the security and privacy requirements and is robust to cyberattacks. It is also a pairing-free elliptic curve cryptography (ECC)-based lightweight authentication scheme. The bilinear pairing operation and the map-to-point hash function in cryptography have not been used because of their high computational costs. Moreover, it provides batch message verification to improve VANETs performance. The NIBPA is compared to existing schemes in terms of computational cost and communication cost. It is also a test for security in the random oracle model (ROM). As a result of security and performance analysis, NIBPA gives better results compared to existing schemes.

Published: May 2023

This paper presents a motorbike-based custom made scanning and mapping system for surveying slums and highly populated urban regions. These vicinities are difficult to reach through standard vehicular scanning systems and require a compact solution as presented in this paper. The system consists of two small range 2D Hokuyo laser scanners mounted in right angle orientations to capture the environment. In addition, the global positioning system, the wheel encoder, the inertial measurement unit, and cameras have been integrated with the system to estimate the pose and visual information. Sensorial information has been used to localise the system using Kalman Filtering. Later, by applying the standard transformations, the 3D point cloud map of the surveyed vicinity has been developed. The scanning system has been tested at various locations including densely populated and slum regions. Precise and detailed 3D mapping results have been obtained, which are further extensively analysed to understand the built structure and the road furniture. The working of the system is found to be quite economical and faster than that of local urban surveying systems.

Published: May 2023

This research is entirely in the nature of library research. Data collected through library research consisting of source data (primary) in the form of books relating to critical studies of Islamic thought. Data processing is entirely "qualitative", because the data encountered is descriptive in the form of verbal statements. As for the method of analysis using "inductive", deductive" and comparative techniques". The results of this study indicate that. IQ, EQ, and SQ, are brain-centered human intelligence forces that have different orientations and functions, but all three can work well together. IQ that is centered on the left brain gives birth to rational or logical intelligence. EQ or Emotional intelligence is centered on the right brain which gives birth to ethical intuitive emotional intelligence. SQ is centered on the network between the two giving birth to a unitive and transcendent spiritual, with this power humans can find meaning behind all the life experiences that have been lived. IQ, EQ, and SQ, based on the view of the Koran, humans have various psychological potentials and these potentials determine human quality. These potentials are spirit, aql, qalb, and nafs. By modern findings these potentials are then translated into IQ, EQ, and SQ. The potentials given by Allah SWT make it possible to bring people who are desired by Allah SWT to worship Allah or become perfect human beings and or vice versa become humans who are disobedient to Allah SWT.
The Behavior of 11 Varieties of Durum Wheat (Triticum durum Desf.) against Phosphate Fertilizer TSP 46%. Effects on Yield Components
Authors: Mazouz Lakhdar
Published: May 2023

The study was conducted at the ITCMI Agricultural Research Station of Oum El Bouaghi during two successive agricultural seasons. The trial set up consists of 11 durum wheat genotypes. The objective was to study the response of these varieties to different inputs of phosphate fertilizer and see their effects on yield components. These components are NEM (Number of ears per square meter), NGE (number of grains per ear), TGW (Thousand grains weight) and Yield. The results indicate that the phosphorus input, in the form of triple superphosphate, allows, at the average dose used in this field trial., 20 kg P2O5.ha-1, to achieve an increase in grain yield between 40 and 60% compared to the phosphorus-free control for all the varieties tested except for the Cirta and Essalam varieties which followed a certain cross order in terms of phosphate fertilizer to increase their grain production. All the other varieties gave their best with only the 20 kg dose.ha-1of P2O5 i.e. 40 kg of TSP 46%. Gtadur and Vitron in this perspective remain among the best varieties. Semito is the variety that seems to be the best adapted to the absence of phosphate fertilization and a low dose. A high TGW is in favor of a better use of the available phosphorus. A more generous rainfall is a favorable factor for a better assimilation of the phosphate fertilizer. These results show that it is possible to reduce the doses of phosphate fertilizer currently used, which represents savings for the farmer in terms of expenses, for non-renewable phosphate deposits a better efficiency of use and for the environment a better preservation.

Authors: Adekunbi
Published: May 2023

This paper presents the mechanism and activation energy adsorption of arsenic (Ase) onto powdered eggshells (PWDEs). The essential compositions and micrograph structure of the PWDEs were determined using standard methods. Adsorption kinetics of Ase onto PWDES were monitored using standard adsorption kinetics models. Effects of pH, particle size, and initial Ase concentrations on the kinetics of Ase adsorption onto PWDES were studied and analysed using analysis of variance (ANOVA). The study revealed acid solubilities were 6.048 % and 6.383 % based on the wet and dried weights respectively, and water solubilities were 0.450 % and 0.536 % based on the wet and dried weights respectively. ΔS° and Ea become more negative or positive with decreasing initial concentration indicating that changes in the selected factors favour the removal process. It was concluded that in the presence of water aluminium, calcium and iron salts undergo displacement reactions. Average cost of producing a kilogram of PDEs was found to be 0.426 USD at the rate of ₦660 per USD.
Palais-Smale approaches to semilinear elliptic equations in unbounded domains
Authors: Wang Hwai-chiuan
Published: May 2023

Let \(\Omega\) be a domain in \(\mathbb{R}^{N}\), \(N\geq1\), and \(2^{\ast}=\infty\) if \(N=1,2\), \(2^{\ast}=\frac{2N}{N-2}\) if \(N\) is greater than 2, \(2 < p < 2^{\ast}\). Consider the semilinear elliptic problem $$\displaylines{ -\Delta u+u=|u|^{p-2}u\quad \hbox{in }\Omega;\\ u\in H_{0}{1}(\Omega). }$$ Let \(H_{0}^{1}(\Omega)\) be the Sobolev space in \(\Omega\). The existence, the nonexistence, and the multiplicity of positive solutions are affected by the geometry and the topology of the domain \(\Omega\). The existence, the nonexistence, and the multiplicity of positive solutions have been the focus of a great deal of research in recent years. That the above equation in a bounded domain admits a positive solution is a classical result. Therefore the only interesting domains in which this equation admits a positive solution are proper unbounded domains. Such elliptic problems are difficult because of the lack of compactness in unbounded domains. Remarkable progress in the study of this kind of problem has been made by P. L. Lions. He developed the concentration-compactness principles for solving a large class of minimization problems with constraints in unbounded domains. The characterization of domains in which this equation admits a positive solution is an important open question. In this monograph, we present various analyses and use them to characterize several categories of domains in which this equation admits a positive solution or multiple solutions.

Published: May 2023

Heavy metals contamination of water and wastewater is a common phenomenon. Industrial wastewaters are usually the cause of heavy metals pollution of the environment. In this work, the adsorptive removal of lead metal ions in aqueous solution is investigated using an activated carbon derived from coconut husk. The activated carbon was modified with NaOH and characterized for functional group, micro-structure and textural properties. The activated carbons have a surface area of 304.38 m
2 /g from 600 °C activation with NaOH modification and 281.19 m
2 /g (300 °C) without modification. FTIR demonstrated the different functional groups present and the SEM images showed the pores on the surface of the activated carbon due to the NaOH modification. The maximum adsorption capacity of 91.70 and 73.90 mg/g were obtained for the coconut husk modified and unmodified adsorbents respectively. The adsorption kinetics for lead metal ions onto both adsorbents can be described by a pseudo-second-order rate model and are well fitted to the Langmuir adsorption isotherm. The results indicated that coconut husk in modified and unmodified forms can be used for the efficient removal of lead (II) ions from water and wastewater.

Selection of the optimum diameter of Spikes and Shafts used on Maize sheller in Nigeria is a major problem for the local fabricators due to which they either over size those components leading to high cost of the shellers or under size them leading to failure of the shellers during operation. To determine the optimum size of the spikes and shaft to be used on Maize sheller, Finite Element Analysis (FEA) were carried out using SolidWorks Premium 2019, to determine the maximum Vonmises Stress, deflection and minimum factor of Safety of those components using the most common size of spikes and shafts used in developing Maize shellers in Bauchi State Nigeria and to recommend the most suitable sizes to be used. From the Simulation of the various sizes of the spikes, it was found that the best size of ribars to be used as the spikes for maize Shellers is either 12 or 14 mm. 12 mm will be subjected to maximum Vonmises stress of 103.092 Mpa at a factor of safety of 2.716 while 14 mm will be subjected to a Maximum stress of 76.57 Mpa at a factor of Safety of 3.66. The most suitable Size for the Shelling shaft was determined to be 20 mm which will be subjected to a maximum Vonmises Stress of 73.32 Mpa at a factor of Safety of 4.8 with a maximum deflection of 0.09 mm.

Published: May 2023

There have been numerous reports linking volatile organic compounds (VOCs) to both acute and chronic health issues as well as environmental damage including global warming. In this study, ammonia was used to enhance the hydrophobicity and affinity of a low-cost, renewable and sustainable activated carbon made from coconut shells (PHAC-AM). Batch and fixed-bed investigations were utilized in determination of removal rates and adsorption capacities for benzene and toluene using activated carbon modified with ammonia (PHAC-AM). The adsorption process was tested using the Tempkin, Freundlich, and Langmuir adsorption isotherms, with Langmuir model being the best and fitted the experimental results, while the Tempkin model being the least. The fitness of the models was justified for suitability and favourability using the root square mean deviation (RSMD), and equilibrium parameter (R
L). According to differences obtained between predicted and experimental values, pseudo-second-order kinetic model was the most suitable in describing kinetics of the two VOCs adsorbed than the pseudo-first-order kinetics. The effects of bed height, initial VOC concentration, and influent flow rate for adsorption of benzene and toluene were investigated in fixed-bed study. For benzene and toluene, 77.30 and 69.40 mg/g were highest obtained bed capacities at initial VOC concentration of 250 mg/L, 4.5 mL/min flow rate, and 2.5 cm bed height, respectively. According to the findings, the synthesized ammonia-treated adsorbent (PHAC-AM), is a sustainable, and suitable for the remediation of VOC contaminated waters.

One of the challenges in lower limb rehabilitation robot design and control for assistance as needed robot is the interaction between the robot and the user. This can be overcome by quantifying the amount of assistance needed by the patient. Which attributed to the precision and accuracy of the estimated knee joint angle by the controller. In this research, the back propagation neural network (BPNN) was trained to estimate the amount of compensation needed by the patients who served as input to the robot. The Electromyogram (EMG) signals, time domain (TD) and time advance domain (TAD) were considered and root means square (RMS), mean absolute value (MAV), variance (VAR) and standard deviation (STD) features were extracted from each domain. Fourteen healthy subjects accepted to validate the experimental setup. However, the best eight subjects data were consider for this article. The features were used separately for training BPNN and the performance of each feature was evaluated. The EMG signals of the protagonist muscle (vastus lateralis) and antagonist muscles (semitendinosus) were used as the input signal to the BPNN after processing the signals. The electro-goniometer reading of the knee joint angle was used as the output to the network. The features were used separately for training BPNN and the performance of each feature was evaluated. The TAD RMSE values were significantly reduced compared to TD with 37.34% , 35.32% , 34.87% and 31.22% for RMS, MAV, VAR and STD features respectively. The result shows that the TAD features have better performance for estimating the knee joint angle.

They are aiming to promote professional standards and ethical principles, to provide a framework for discussing and finding a universally accepted definition and to increase the credibility of the profession. The purpose of this paper is to examine the extent of which the objectives of professional public relations organizations in Romania are similar to those of associations in other countries and in what way, and if they contribute to the professionalization of the PR industry.
Using a police warning
system to eliminate errors in intelligent violation detection systems
Authors: Mohammad Sadat Hoseini Seyyed
Published: May 2023

A broad range of diverse technologies under the generic topic of intelligent transportation systems holds the answer to many transportation problems. Tailgating and the failure to maintain sufficient distance from the next vehicle are among the biggest causes of motorway accidents. There are intelligent systems to detect this violation. Their insufficient accuracy is, however, the reason they are used with reluctance. In this research, a police warning system is proposed to note the detected violating drivers by a short message service. If the violation is repeated, the driver will be fined. Using probability logic, it has been shown that by the proposed system, we can be sure that the error in traffic ticketing will be very low. A survey of police officers found that most of them welcome the proposed system.

U radu se procjenjuje rizik ugroženosti spolne viktimizacije djece analizom stanja sigurnosti turističkih objekata dobivene na temelju operativno-preventivnog rada policijskih službenika Odjela prevencije na području Policijske uprave istarske tijekom turističke sezone. Na temelju provedenih preventivnih aktivnosti u turističkoj sezoni te uočavanja trenutačnog stanja i kvalitete poduzimanja sveukupnih mjera zaštite i štićenja turističkih objekata utvrđene su, a potom i analizirane opasnosti i rizici od počinjenja kaznenih djela na štetu djece. Upravo je jedan od preduvjeta za pravilno i uspješno planiranje i ostvarivanje mjera pravilna i konkretna procjena različitih izvora i oblika ugroženosti (Perić, 1987). Pregledom relevantne literature, praćenjem stanja i pojavnih oblika kaznenih djela, neposrednim obilaskom i vizualnim pregledom objekata, zatim razgovorima s odgovornima i osobama zaduženim za osiguranje turističkih objekata prikupljeni su podaci koji su upotrijebljeni za izradu SWOT analize stanja u objektima, čiji će rezultati pridonijeti poduzimanju mjera zaštite i usklađivanju preventivnih mjera i aktivnosti koje poduzima policija. Slijedom navedenog, ovaj rad donosi preporuke za turističke kuće te smjernice za rad policijskih službenika. Preporuke turističkim kućama temelje se na povećanju preventivne aktivnosti,provedbi ciljanih edukacija i poticanja samozaštitnog ponašanja među gostima, kao i poticanja komunikacije s policijom te, naposljetku, za provedbu prikupljanja operativnih informacija koje bi pridonijele rješavanju kaznenih djela. Preporuke za rad policijskih službenika odnose se na specifičnu problematiku ugroženosti djece u turističkim objektima, preventivni rad i postupanje u slučajevima počinjenja kaznenih djela spolnog zlostavljanja i iskorištavanja djeteta.

TiO2/Ni coating has been deposited onto the electrodes by chemical vapour deposition to improve electrode life during resistance welding of Zn- coated steels. However, welding results revealed that molten Zn penetrates into coating through the cracks and then reacts with substrate copper alloy to form brasses. In the present work, laser treatment was performed on the TiO2/Ni coated electrodes to eliminate cracks formed in the as-deposited TiO2/Ni coating. In addition, a chemical vapour deposition of Ni, TiO2/Ni and Ni has also been carried out to improve coating quality. On the other hand, a Ti coating was also investigated. Those coatings were characterized by electro-microscopy, energy- dispersive X-ray analysis, X-ray diffraction and micro-hardness tests. The results showed that cracks within the as-deposited TiO2/Ni coating could be eliminated with the use of laser treatment and chemical vapour deposition process. However, softening of copper substrate after laser treatment was a problem that restricted welding performance. Welding tests showed that the multi-layer TiO2/Ni coating acted as a better barrier to decrease alloying between the copper alloy and molten Zn as well as pitting (erosion) of electrode. The TiO2 coating demonstrates its potential application on the electrode to further improve the electrode’s life Key Word: Electrode; Molecular; Titanium; Nanotechnology; Nickel.
