Abstract

Ibn al-Haytham or better known as Alhazen (965-1040 AD) was a great Muslim scientist who mastered many disciplines. One of his works entitled "Qawl fi Samt al-Qibla bi al-Hisab" describes a mathematical method for determining the direction of Qibla. In this paper, Ibn al-Haytham's algorithm is modified, thus the algorithm can determine the Qibla direction on the entire surface of the globe. Then, Ibn al-Haytham's mathematical method is compared with modern spherical trigonometry methods and our previous research using al-Biruni’s method. The computational results show that all methods have the same accuracy, and show that ibn al-Haytham's method is still relevant now. Therefore, the modified ibn al-Haytham method algorithm was implemented to develop a Qibla direction device and interface based on Raspberry Pi 4, GPS module, digital compass, and Processing 3 software. The implementation results show that the device can display the Qibla direction interface according to numerical calculations with high accuracy, real-time, and dynamic interface.

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

In this study brass used as a sample is brass which is used as a raw material for LPG (Liquified Petroleum Gas) valves. Two samples were taken which were prepared before the composition test and microstructure test. From the results of the micro test, it is found that the brass phase structure is the ? proeutectic phase and the ? phase. The proeutectic phase ? has an FCC structure while the ? phase has a BCC structure. There are also black dots which are Lead with different percentages for each sample.Lead tends to be in the particle-shapedside.

Abstract

Makalah ini menyajikan sebuah sistem 3-D autonomous baru dengan istilah empat kuadrat. Sistem dengan lima titik ekuilibrium memiliki perilaku dinamika chaos kompleks. Hal ini dapat menghasilkan banyak attractor chaos tunggal yang berbeda dan attractor chaos ganda dengan mengubah parameter kontrol pembangkit sinyal chaos. Perilaku dinamis yang kompleks dari sistem yang diteliti lebih lanjut dengan cara menganalsis diagram fase, spektrum Lyapunov eksponen, sistem dissipative, diagram bifurkasi dan peta Poincaré. Rangkaian fisik hasil pendekatan eksperimen menggunakan MultiSIM 10.0 dari attractor chaos menunjukkan hasil yang sama dengan simulasi numerik menggunakan MATLAB 2010. Yang lebih penting orbit chaos yang padat dihasilkan oleh sirkuit ini akan memberikan sebuah fitur lintasan robot patroli yang tidak terduga, yang dimanfaatkan dalam pengontrolan fasilitas militer. Hal ini mendorong bagi kami untuk mengembangkan sistem robot cerdas. Pada sistem mobile robot patrol ini, sinyal chaos digunakan untuk mengontrol pergerakan arah robot dan diaplikasikan untuk robot patroli dalam bidang militer. Kelebihan robot bernavigasi chaos ini adalah karena robot ini merupakan robot autonomous digital, sehingga sistem program yang dibuat menggunakan mikrokontroler sebagai kendali geraknya. Selain itu, kami telah mengembangkam model matematika dari kinematika robot dan pendekatan validasi menggunakan MATLAB 2010.
