In modern world many countries are working on different technologies. Hence, safety of soldiers and army personnel who fight for national security of their respective country need to considered. During warfare many of the soldiers lose their lives in abandoned areas or at borders. Landmines are an explosive weapon which may be or may not be buried under the soil and activated by a mere pressure of 9kg when someone steps on it. It also has an adverse effect on environment such as damage to soil structure, reducing soil productivity and increase vulnerability of soil to water and wind erosion. Mines also kill innocent civilians and soldiers after war ends. In order to save the lives of soldiers and diffuse the mines this paper is proposing a robotic vehicle with a metal detector which is capable of sensing mine ahead of it. It will also detect position of landmine and send latitude, longitude coordinates using GPS module. and also, Video surveillance is the process of monitoring a situation, an area or a person. This generally occurs in a military scenario where surveillance of borderlines and enemy territory is essential to a country’s safety. Human surveillance is achieved by deploying personnel near sensitive areas in order to constantly monitor for changes. But humans do have their limitations, and deployment in inaccessible places is not always possible. We have developed a robot which can be used for video surveillance & monitoring which can be controlled through a GUI. The control mechanism is provided with a video transmission facility. The video transmission is practically achieved through high-speed image transmission. Initially, the robot will be equipped with a camera which will capture the scenes and transfer the images to the server on which the user will be controlling and watching the live feed. Key Words: Node MCU (ESP8266), GPS Module, Metal Detector, Motor Driver (L298N), ESP32-cam module, Surveillance Robot, landmine detection, fire detection, temperature and humidity sensing.

Published: October 2023

Structural Engineering is a Branch of civil engineering which deals in the determination of behaviour of structures in order to predict the responses of real structures like bridges, Buildings, etc. under the improvement of expected loading and external environment during the service life of the structure. Structural Engineers these days are up against the challenging task of striving for the most efficient and most economical design with accuracy in solution while guaranteeing the final design of a building is serviceable for its design lifetime. In reality it’s very difficult to predict with certainty how much damage a building will experience for a given level of ground motion, because there are number of factors that affect the behaviour of the structural systems. The objective is to emphasize on structural behaviour of a commercial building (basement + ground+10 stories) installed with flat slabs for Bangalore (Zone 2) pertaining to medium soil. The building model is designed and analysed using ETABS (Extended Three dimensional analysis of Building System) and SAFE. ETABS is the ultimate integrated software package for the structural analysis and design of buildings. SAFE is the ultimate tool for designing concrete floor and foundation systems. The lateral loads induced from wind and earthquakes in the design and analysis of building is considered. The dead loads are calculated as per IS 875(part 1)-1987, live load is taken as per IS 875(part 2)-1987, earthquake load has been taken as per IS 1893-2002(part 1) and wind load has been taken from IS 875 (part 3)1987. The manual calculations for the design of structural members were compared with the software results which were found to be satisfactory. All the design and detailing procedures for structural members were carried out as per the guidelines of Bureau of Indian Standard code books.
Design Philosophy and Seismic Analysis of a Multi-Storey Building (B+G+10) with Flat Slabs in Seismic Zone II Using ETABS and SAFE Software
Authors: Patel Asst. Prof Nirav , Magar Chhining Lal Thapa
Published: October 2023

This journal paper presents the design philosophy and seismic analysis of a multi-storey building (B+G+10) with flat slabs located in Seismic Zone II. With the growing population and limited resources, vertical expansion has become a necessity. The economy's development has attracted foreign companies and innovative entrepreneurs, requiring the construction of high- end, safe workplaces. High-rise structures face challenges from wind and seismic loads, making proper design and analysis crucial for safety. The design philosophy emphasizes the use of reinforced concrete due to its versatility, durability, and fire resistance. Reinforced concrete, a composite material of concrete and steel reinforcement, ensures strain compatibility and load sharing between the materials. The paper discusses various design loads, including dead loads, live loads, wind loads, and earthquake (seismic) loads. Dead loads encompass the self-weight and permanent attachments to the structure, while live loads consider dynamic factors due to occupancy. Wind loads are assessed based on the local wind conditions, and earthquake loads are determined using seismic codes. Design principles for foundations, columns, and footings are addressed, with a focus on ensuring structural stability, safety, and uniform settlement. The depth of the foundation is calculated using Rankine's formula, considering soil properties. Column design is crucial, with short and long column classifications, and minimum eccentricity requirements are detailed. The seismic analysis of the building involves the use of ETABS and SAFE software, which enable engineers to model the structure and assess its response to seismic forces. The combination of a sound design philosophy and comprehensive seismic analysis tools ensures the building's ability to withstand various loads, thereby contributing to safety and sustainability.

Foundation is a load transferring part of structure to soil. Recent trends have made replacement of conventional practice of isolated and eccentric footing with Mat foundation. Necessity to choose Mat foundation over conventional isolated footing is when the bearing capacity of soil is considerably low. However, consideration of properties of soil in contact with the foundation has not been applied in detail practice which is also called soil structure interaction (SSI) will significantly affects the performance of structures. Our study has used Winkler’s method to model the foundation soil as spring Moreover, three different buildings of five, seven and nine story were modeled using finite element method to incorporate the soil structure interaction effects. performance parameter to measure the performance of the structures was done using Roof displacement. This research reports the change in natural time period, roof displacement and base shear due to consideration of SSI and concludes with the urge of consideration of SSI in structural analysis and design.

Road drainage is vital for the safety and longevity of transportation infrastructure. Designing effective drainage facilities, including culverts, requires a precise understanding of discharge-frequency relationships. Culverts, which allow water to flow beneath roads, must consider various engineering and environmental factors. In Ghana, the Ghana Highway Authority expects culvert designs to meet peak flow specifications, but evaluating the design flood of each culvert is time-consuming. Typically, drainage culvert designs rely on estimations, which can lead to inappropriate sizes. This study aimed to assess the adequacy of existing cross culverts and propose suitable sizes for inefficient ones on the Sakpeigu-Chereponi road (7+700-7+750) in the Yendi municipality. The study employed integrated GIS and hydrological models to delineate and estimate peak flow using the modified rational method. The catchment for the scheduled culverts was delineated, with a peak flow of 44.552 m3/s for a 25-year design period. However, the combined capacity (32.066 m3/s) of the scheduled culvert sizes was insufficient, resulting in an excess discharge of 12.486 m3/s. A new culvert schedule was proposed, featuring a 3m X 3m box culvert with a capacity of 70.148 m3/s for the entire section (7+100 - 7+750) to address the inadequacy.

The increase in use and demand for electric vehicles (EVs) has surged the need for battery recycling methods for these batteries. This report highlights a review analysis of a few recycling methods for EV batteries, such as direct recycling, mechanical recycling, hydrometallurgical recycling, and pyrometallurgical recycling. The purpose of this review is to understand the current state of the technology, the challenges of each method, and the future developments while considering factors such as efficiency, cost, waste production, and more. Direct recycling is reusing EV batteries without disassembling them, whereas mechanical recycling entails discharging, dismantling, crushing, and sorting them. Hydrometallurgical and pyrometallurgical recycling processes both give considerable improvements in metal recovery, with hydrometallurgical recycling including acid leaching and pyrometallurgical recycling using metal extraction. Analyzing the various recycling methods for EV batteries, the effort to improve or innovate the methods will help achieve a more sustainable and effective method to address the EV battery waste, which promotes a circular economy.
Gyepesített területek fajgazdagságának növelése kolonizációs ablakok segítségével

Published: October 2023

Vizsgálatunk célja vetett gyepek fajgazdagságának növelése volt, melynek során egy sokfajos magkeveréket vetettünk úgynevezett „kolonizációs ablakokba”. A Hortobágyi Nemzeti Parkban nyolc – 2005-ben gyepesített területen –, 2013 őszén területenként három darab (1 m2, 4 m2 és 16 m2) kolonizációs ablakot létesítettünk. Talajmunkákat követően az ablakokba szikesés löszgyepi célfajok magjait tartalmazó, 35 fajból összeállított sokfajos magkeveréket vetettünk. A vizsgálat során a vetett fajok mindegyikét sikerült megtalálnunk: 31 faj már 2014-ben megtelepedett, 7 faj borítása szignifikánsan nőtt 2015-re. Kimutattuk, hogy a célfajok fajszáma és összborítása is a nagyobb méretű ablakokban volt a legnagyobb. A legsikeresebben betelepülő faj a Dianthus pontederae volt, amelynek minden ablaktípusban növekedett a borítása. A gyomok borítása 2014-ben 26-31%, 2015-ben 16-23% volt, így intenzív gyomosodás nem veszélyezteti a gyepesített területeket. A kolonizációs ablakok alkalmasak a gyepesített területek fajgazdagságának növelésére. A talajelőkészítés alkalmas volt a vetett kompetítor füvek dominanciájának megtörésére, ezáltal csökkentette a mikroélőhely-limitációt, a diverz magkeverék vetése pedig csökkentette a propagulum-limitációt. Ahhoz, hogy a célfajok a környező területekre is kiterjedjenek, elengedhetetlen a területek hosszú távú megfelelő kezelése.

The results of global climate change can be observed in climate of Hungary. In the last couple of decades significant have been observed extremes in the climate of Europe due to global climate change (IPCC, 2014), which the irregular alternation of droughts and floods could be traced in the Carpathian Basin (Bartholy et al., 2009, 2014). The river floodplains and adjacent wetlands were outstanding from a nature conservation point of view due to the increasingly exposed to this change (Capon et al., 2013). Because of climatic effects, floodplain areas are even more exposed to the spread of invasive species (Szollát and Schmotzer, 2004; Schmotzer, 2008; Füri 2000; Füri and Kelemen 1997; Čížková-Končalová et al. 2013), and changes in land use also aggravate this problem (Mosner, 2015; Penksza et al., 2012). The aim of this study is to present the impact of extreme climatic situations on vegetation in grazed grasslands. The question was, which Festuca species occurs in addition to this? Can Festuca javorkae or Festuca pseudovina be found. The Festuca javorkae, which was related to Festuca rupicola, could also be problematic, although this species was clarified (Penksza, 2000, 2009a; Penksza et al., 2020, 2021; Markgraf-Dannenberg, 1980) and its species differentiation was shown using molecular studies by Bnauer et al. (2003) and Galli et al. (2006). According to the description of association Salvio nemorosae-Festucetum rupicolae, Festuca rupicola is one of the species of the association that appeared in the present study.

A scratch test was used to assess adhesion. The model tribological tests were carried out ina rotary motion under technically dry friction conditions, lubricated with Ringer’s solution. In the case oftechnically dry friction, the analysis of the tribological test results indicated that the TiN:Ag coating wascharacterised by higher resistance to motion and lower wear compared to Ti13Nb13Zr. Friction coefficientsregistered during friction subject to lubrication with Ringer’s solution were compared for both materials;however, the surface wear was significantly lower in titanium alloy. The scratch test pointed towards highadhesion of the TiN:Ag coating. The study results provide insight into Ti13Nb13Zr alloy, titanium nitridecoatings and their potential use for surgical instruments.

Hot rolling of grain-oriented high silicon steel is related to technical problems such as high temperature andlong rolling campaigns with strips of the same width. Numerous methods may be carried out as a solutionto these problems. Before the rolling campaign, all rolls of finishing stands are exchanged. The campaign isscheduled with additional exchanges of rolls on two last stands in two stages. A roll’s wear increases with thequantity of rolled material and may lead to strip profile deformation. Exchanging the rolls ensures the requiredsteel quality and prevents losses caused by quality defects. This work identifies factors affecting the workroll's wear and refers to the material from which rolls are made. This work aimed to determine the wear ofwork rolls of the finishing group rolling mills during the rolling of high-silicon steel. The work presents wearanalyses of 30 rolls. It was analysed depending on roll type and high silicon steel rolled material quantity.Compared wear of rolls after rolling high-silicon steel and black sheet. By analysing the distribution of rollwear along the length of the roll, it was found that the wear of working rolls directly affects the geometry ofthe rolled sheet, which may affect the quality of the strip profile of the rolled sheet.
ON AN IMPORTANT OBSERVATION REGARDING SOME HYDROMAGNETIC MOTIONS OF MAXWELL FLUIDS AND ITS APPLICATIONS*

Published: October 2023

The problem of exact solutions for isothermal motions of non­Newtonian fluids is of interest yet and a new way to get them is wel­come. In this work an important observation regarding the governing equations corresponding to some isothermal hydromagnetic unidirec­tional motions of incompressible Maxwell fluids is brought to light. It allows us to easily determine exact solutions for motions with shear stress or velocity on the boundary when similar solutions for motions with velocity, respectively shear stress on the boundary are know. To exemplify, the solutions of some hydromagnetic motion problems of Maxwell fluids with velocity on the boundary are used to generate exact steady state solutions for similar motions of same fluids with shear stress on the boundary. These solutions are very important for the experimental researchers who want to know the required time to reach the steady state.

Published: October 2023

In this note, we consider the number of k’s in all the partitions of n in order to provide a new proof of a classical identity involving Euler’s partition function p(n) and the sum of the positive divisors function a(n). New relations connecting classical functions of multiplicative number theory with the partition function p(n) from additive number theory are introduced in this context. The fascinating feature of these relations is their common nature. A new identity for the number of 1’s in all the partitions of n is derived in this context.

In this note, we study the optimal control of a nonisothermal phase field system of Cahn-Hilliard type that constitutes an extension of the classical Caginalp model for nonisothermal phase transitions with a conserved order parameter. It couples a Cahn-Hilliard type equation with source term for the order parameter with the universal balance law of internal energy. In place of the standard Fourier form, the con­stitutive law of the heat flux is assumed in the form given by the theory developed by Green and Naghdi, which accounts for a possible thermal memory of the evolution. This has the consequence that the balance law of internal energy becomes a second-order in time equation for the thermal displacement or freezing index, that is, a primitive with respect to time of the temperature. Another particular feature of our system is the presence of the source term in the equation for the order parameter, which entails further mathematical difficulties because the mass conservation of the order parameter is no longer satisfied. In this paper, we study the case that the double-well potential driving the evolution of the phase transition is given by the nondifferentiable dou­ble obstacle potential, thereby complementing recent results obtained for the differentiable cases of regular and logarithmic potentials. Be­sides existence results, we derive first-order necessary optimality condi­tions for the control problem. The analysis is carried out by employing the so-called deep quench approximation in which the nondifferentiable double obstacle potential is approximated by a family of potentials of logarithmic structure for which meaningful first-order necessary opti­mality conditions in terms of suitable adjoint systems and variational inequalities are available. Since the results for the logarithmic poten­tials crucially depend on the validity of the so-called strict separation property which is only available in the spatially two-dimensional situ­ation, our whole analysis is restricted to the two-dimensional case.

The paper deals with the study of solutions for some weak varia­tional control inequalities of vector type, and the efficient solutions to the corresponding optimization problem. More exactly, to formulate and prove the principal results, we consider the Frechet differentia­bility, the concept of invex set, and invexity & pseudoinvexity of the curvilinear integral type functionals which are involved in the study.

In this paper we consider in a bounded domain Q C RN a Steklov- like eigenvalue problem involving the (p, q)-Laplacian plus some poten­tials. Under suitable assumptions, using the Nehari manifold method and a variational approach, we are able to determine the full eigenvalue set of this problem as being an open interval (A*, +^) with A* > 0.

We consider an abstract problem P in a metric space X which has a unique solution u G X. Our aim in this current paper is two folds: first, to provide a convergence criterion to the solution of Problem P , that is, to give necessary and sufficient conditions on a sequence {un} C X which guarantee the convergence un ^ u in the space X; second, to find a Tyknonov triple T such that a sequence {un} C X is a T -approximating sequence if and only if it converges to u. The two problems stated above, associated to the original Problem P , are closely related. We illustrate how they can be solved in three particu­lar cases of Problem P: a variational inequality in a Hilbert space, a fixed point problem in a metric space and a minimization problem in a reflexive Banach space. For each of these problems we state and prove a convergence criterion that we use to define a convenient Tykhonov triple T which requires the condition stated above. We also show how the convergence criterion and the corresponding T -well posedness con­cept can be used to deduce convergence and classical well-posedness results, respectively.

Enzyme-catalysed reactions are chemical reactions within cells in which the rate of the reaction is significantly increased through the action of enzymes. They are usually part of large and complex bio¬chemical networks, which form the central processing units of the living cell. Enzymatic reactions often operate on multiple time scales, which can be characterized as being either fast or slow. The quasi steady¬state approximation (QSSA) utilizes time scale separation to pro ject these complex models onto lower-dimensional slow manifolds. In this paper, we investigate the validity of a quasi steady-state assumption for enzyme-catalysed biochemical reactions with competitive inhibition that are subject to a constant substrate input. Necessary and sufficient conditions for the validity of these assumptions were derived and were shown to be dependent, among others, on the substrate input. The validity conditions are numerically verified using the classical Runge- Kutta method.

This paper is devoted to the analysis of the mean-square stability of a class of linear time-varying impulsive Ito-type stochastic systems. We succeed to obtain necessary and sufficient stability conditions in the general time-varying case. This result is obtained thanks to the theory of positive operators on Hilbert spaces. The problem of state­feedback stabilization is treated as well.

In this paper, we study and introduce a self adaptive method to­gether with a Halpern iterative algorithm for approximating solutions of multiple-sets split monotone variational inclusion problem which in­cludes the multiple-sets split feasibility problem, split feasibility prob­lem, split monotone variational inclusion problem and split variational inclusion problem, to mention a few. Using our iterative algorithm, we prove a strong convergence result for approximating the solution of the aforementioned problems. Numerical examples on finite-dimensional and infinite-dimensional spaces are displayed to illustrate the perfor­mance of our iterative method. The result discussed in this article extends and complements many related results in literature.

Authors:   University of Oradea, Romania, Galt S. G. ,   and Academy of Romanian Scientists, Romania
Published: October 2023

Since the classical asymptotic theorems of Voronovskaya-type for positive and linear operators are in fact based on the Taylor’s formula which is a very particular case of Lagrange-Hermite interpolation for­mula, in the recent paper Gal [3], I have obtained semi-discrete quanti­tative Voronovskaya-type theorems based on other Lagrange-Hermite interpolation formulas, like Lagrange interpolation on two and three simple knots and Hermite interpolation on two knots, one simple and the other one double. In the present paper we obtain a semi-discrete quantitative Voronovskaya-type theorem based on Lagrange interpola­tion on arbitrary p + 1 simple distinct knots.
ON THE EQUILIBRIUM EQUATIONS OF LINEAR 6-PARAMETER ELASTIC SHELLS
Authors:   University Duisburg-Essen, Germany, Blrsan M. ,   and Institute of Mathematics Octav Mayer of the Romanian Academy, Romania
Published: October 2023

We consider the linearized theory of 6-parameter elastic shells with general anisotropy. We derive the equilibrium equations from the virtual power statement and formulate the corresponding variational problem in the suitable functional framework. Then, using a Korn-type inequality for the linearized strain measures we prove the existence and uniqueness of weak solutions. Finally, we show that our general theo­rem can be applied to obtain existence results in the case of isotropic elastic shells. We illustrate this procedure by investigating three differ­ent linear shell models established previously in the literature, namely the simplified isotropic 6-parameter shell, the Cosserat isotropic model, and the higher-order 6-parameter Cosserat model.
