Abstract

A new chaotic system with line equilibrium is introduced in this paper. This system consists of five terms with two transcendental nonlinearities and two quadratic nonlinearities. Various tools of dynamical system such as phase portraits, Lyapunov exponents, Kaplan-Yorke dimension, bifurcation diagram and Poincarè map are used. It is interesting that this system has a line of fixed points and can display chaotic attractors. Next, this paper discusses control using passive control method. One example is given to insure the theoretical analysis. Finally, for the  new chaotic system, An electronic circuit for realizing the chaotic system has been implemented. The numerical simulation by using MATLAB 2010 and implementation of circuit simulations by using MultiSIM 10.0 have been performed in this study.

Abstract

This paper reports the finding a new chaotic system with a pear-shaped equilibrium curve and makes a valuable addition to existing chaotic systems with infinite equilibrium points in the literature. The new chaotic system has a total of five nonlinearities. Lyapunov exponents of the new chaotic system are studied for verifying chaos properties and phase portraits of the new system are unveiled. An electronic circuit simulation of the new chaotic system with pear-shaped equilibrium curve is shown using Multisim to check the model feasibility.

Abstract

This paper announces a new three-dimensional chaotic jerk system with two saddle-focus equilibrium points and gives a dynamic analysis of the properties of the jerk system such as Lyapunov exponents, phase portraits, Kaplan-Yorke dimension and equilibrium points. By modifying the Genesio-Tesi jerk dynamics (1992), a new jerk system is derived in this research study. The new jerk model is equipped with multistability and dissipative chaos with two saddle-foci equilibrium points. By invoking backstepping technique, new results for synchronizing chaos between the proposed jerk models are successfully yielded. MultiSim software is used to implement a circuit model for the new jerk dynamics. A good qualitative agreement has been shown between the MATLAB simulations of the theoretical chaotic jerk model and the MultiSIM results

Abstract

Rikitake dynamo system (1958) is a famous two-disk dynamo model that is capable of executing nonlinear chaotic oscillations similar to the chaotic oscillations as revealed by palaeomagnetic study. First, we detail the Rikitake dynamo system, its signal plots and important dynamic properties. Then a circuit design using Multisim is carried out for the Rikitake dynamo system. New synchronous quasi-sliding mode control (QSMC) for Rikitake chaotic system is studied in this paper. Furthermore, the selection on switching surface and the existence of QSMC scheme is also designed in this paper. The efficiency of the QSMC scheme is illustrated with MATLAB plots.

Abstract

Chaos theory has several applications in science and engineering. In this work, we announce a new two-scroll chaotic system with two nonlinearities. The dynamical properties of the system such as dissipativity, equilibrium points, Lyapunov exponents, Kaplan-Yorke dimension and bifurcation diagram are explored in detail. The presence of coexisting chaotic attractors, coexisting chaotic and periodic attractors in the system is also investigated. In addition, the offset boosting of a variable in the new chaotic system is achieved by adding a single controlled constant. It is shown that the new chaotic system has rotation symmetry about the z-axis. An electronic circuit simulation of the new two-scroll chaotic system is built using Multisim to check the feasibility of the theoretical model.

Abstract

Dengan perkembangan teknologi informasi dan komunikasi pengiriman kemanan data sangatlah diperlukan. Oleh karena itu, kami mengusulkan sistem enkripsi menggunakan sinyal chaos dengan inputan sinyal suara berdasarkan kombinasi dua sinyal yang berbeda. Untuk mendapatkan sinyal chaos yang baik, maka phenomena chaos yang dihasilkan oleh sistem Malasoma harus dipelajari secara intensif. Studi awal penelitian ini adalah menganalisis titik ekuilibrium, Lyapunov eksponen, Kaplan Yorke dan analisis peta Poincaré. Fokus terakhir makalah ini adalah aplikasi sinyal chaos dalam sistem kemanan komunikasi dengan input sinyal suara telah disajikan secara lengkap. Hasil enkripsi menggunakan pendekatan simulasi numerik Matlab menunjukkan bahwa sistem Malasoma sangat baik untuk dijadikan sistem keamanan data.

Abstract

The Ar-Ridho PKBM and the Majelis Pemberdayaan Masyarakat (MPM) of the Muhammadiyah Regional Leadership of the city of Tasikmalaya have a large contribution to the community empowerment program in the city of Tasikmalaya. However, the institution has limitations related to training, limited funds, human resources, and other supporting facilities. The problem is related to the lack of Tasikmalaya city people who have skills in the field of technology, so people do not have good skills in dealing with global competition. Therefore, we conduct electronic assembly training activities with a focus on providing electronic assembly skills for the millennial generation. The material presented includes the concept of introducing electronic components, measuring electronics and assembling light sensors on garden lights. With the provision of skills such as this millennial generation is expected to have the basic skills that are used as provisions for entrepreneurship and become productive economically and socially.

Abstract

A new multi-stable system with a double-scroll chaotic attractor is developed in this paper. Signal plots are simulated using MATLAB and multi-stability is established by showing two different coexisting double-scroll chaotic attractors for different states and same set of parameters. Using integral sliding control, synchronized chaotic attractors are achieved between drive-response chaotic attractors. A MultiSim circuit is designed for the new chaotic attractor, which is useful for practical engineering realizations.

Abstract

A composite material is a material that is a mixture of two or more macroscopically mixed materials, so the properties of its forming material are still clearly visible. In this study, the type of fiber used was the natural fiber of mendong. This mendong fiber is made into a composite material using the Hand Lay-up method with four variations in fiber volume, namely (30%, 40%, 50%, and 60%). The fiber binding material (matrix) used is Epoxy. This study aims to determine the characteristics of jack fibers in jack fiber composite materials with an epoxy matrix against tensile strength and modulus etalciticity. Tensile testing refers to the ASTM D 638 Standard. To find out the type of fault from the tensile test results, macro photos are used and find out the shape of the fault and the failure pattern that occurs in composite specimens. From the test results, it is clear that the difference in the composite material of mendong fiber using Epoxy, that with a fiber volume fraction of 60% greater mechanical properties
