In this paper we consider Ising models with competing interactions defined on semi-infinite Cayley tree of second order. Phase diagram of such models contain new modulated phases, in addition to the expected paramagnetic and ferromagnetic phase. The aim of this paper is to select phases of these models with competing interactions on Cayley tree whi

دلالة الألفاظ وما يعتريها من تغير وتطور في دلالاا من أهم قضايا الدراسات اللغوية الحديثة، بل إا أصبحت فرعا علميا بذاته في عصرنا. وتنبع أهمية الدلالة والتغير الدلالي من أثرهما الكبير في م�

The term game in game theory means a problem, where some of the people or groups (players) share a set of rules and regulations that create the conditions and events that make up the beginning of the game. For instance, in the trade market, the buyers and sellers of some commodities interact in a random way. The reputation of sellers effects on inc

Rethinking the Culture of Knowledge and its Implications for Peace and Sustainable Developments in the Philippines By Dr. Alizaman D. Gamon Dr. Mariam Saidona Tagoranao ABSTRACT Over the years, the given socio-economic landscape of the Philippines and its remarkable agenda for national integration via education has made major transformational chang

This chapter is talking about one of the famous and greatest Islamic astronomers and mathematicians around the world; AI-Battani has great and significant contributions in astronomy and mathematics. In astronomy, he has astronomical observations for more than forty years. In addition, he did some corrections upon Ptolemy's results and made some

Kernel grading is considered one of the hectic labor processes in terms of nuts arrangement and classification. This paper aims to develop a mechanized system that will liberate the exhaustion of human resources and perform with promising output in terms of grading. This paper is focused on the grading of walnut kernels. Walnut is one of the main m

The coronavirus disease 2019 (COVID-19), which emerged from Wuhan, China, is now a pandemic, affecting across the globe. Bangladesh also is experiencing the rapid growth of COVID-19 infection and death cases started from 8th March 2020. The purpose of providing a simple yet effective explanatory model for prediction of the future evolution of the c

This paper investigates the applicability of a proposed digital image algorithm for filling cracks in digitized paintings. Filling is defined as a process of modifying/restoring damaged regions or lost areas in images. Old paintings affected by cracks suffer from decreased cultural heritage quality. Paintings that are digitized typically suffer dam

This paper reports the effects of polypropylene-graft-maleic anhydride (PP-gMA) and graphene nanoplatelet (GNP on tensile stress of various PLA/PP weight ratio. The PLA/PP blends prepared with the ratio 70/30, 80/20, and 90/10 with the addition of PP-g-MA (1 to 5 phr) and GNP (1 to 3 phr) by using an injection molding machine. The tensile stress (M

This work reports the effect of doping concentration on the energy-band structure of semiconductor materials. The research focuses on the resultant values of bandgap energy and its depletion region (length/area), based on the initial concentrations of doping which are the donors and acceptors. The energy-band diagram is simulated by initializing th
