Super edge-magic deficiency of join-product graphs

A graph $G$ is called \textit{super edge-magic} if there exists a bijective function $f$ from $V(G) \cup E(G)$ to $\{1, 2, \ldots, |V(G) \cup E(G)|\}$ such that $f(V(G)) = \{1, 2, \ldots, |V(G)|\}$ and $f(x) + f(xy) + f(y)$ is a constant $k$ for every edge $xy$ of $G$. Furthermore, the \textit{super edge-magic deficiency} of a graph $G$ is either the minimum nonnegative integer $n$ such that $G \cup nK_1$ is super edge-magic or $+\infty$ if there exists no such integer. \emph{Join product} of two graphs is their graph union with additional edges that connect all vertices of the first graph to each vertex of the second graph. In this paper, we study the super edge-magic deficiencies of a wheel minus an edge and join products of a path, a star, and a cycle, respectively, with isolated vertices.Comment: 11 page

PENGEMBANGAN KARAKTER SISWA MELALUI THINKING EMPOWERMENT BY QUESTIONING DAN IQ TERHADAP KEMAMPUAN PEMAHAMAN GEOGRAFI SISWA SMA

The main objective in this study is to find and reveal the effects of Thinking Empowerment by Questioning and IQ the ability of student comprehensive at SMA 2 Blitar. In addition, this study also aimed to test is Intelligence Quotient (IQ) influence on comprehension ability of students and ability to test whether there is an interaction between strategy and IQ TEQ the comprehension ability of students. This research conduct with quasi-experimental which is subject is class XI. 2 as an experimental class and class IS. 5 as the control class. The experiment class used the TEQ strategy, whereas the control class using lecture methods. The research instrument is an essay test for the pretest and posttest. Data analysis used two-way ANOVA method whereby data was analised using the SPSS 16.0 program. Based on data analysis, TEQ strategies usage has significant effect on the geography student comprehension ability. IQ has significantly influence on the geography student comprehension ability. Interaction between TEQ strategies and IQ not significant effect on the geography student comprehension ability

Pengaruh Fungsi Pengendalian Oleh Kepala Sekolah Terhadap Disiplin Siswa

: This article explain the effect of controling function by school principal to student disciple. Controling function by school principal consist of determining regulation for student, monitoring of student behavior, and correction action. Data collection using questionair and the sample are students of 3th grade of Publict Senior High School in Mojokerto. The sampling system using proportional random sampling. Data analysis using desciptive analysis and regression. The?é?á research result shows that controling function by school principal is good and student discipline are hight. Controling function by school principal has significant effect to student discipline. The effective contribution of controling function by school principal to student discipline is 7,461 %. Further explation shows that there is no effect of determination of refulation for student to student discipline, there is no effect of behavior monitoring to student discipline, and there is a significant effect of correction action by school principal to student discipline. ?é?

PENGEMBANGAN SUDUT BUKU KELAS SEBAGAI UPAYA MENUMBUHKAN MINAT BACA SISWA DI SEKOLAH DASAR

Kemampuan membaca siswa di Indonesia saat ini tergolong rendah. Hal ini berdasar pada hasil tes PIRLS dan PISA, serta hasil temuan dari UNESCO terkait kebiasaan membaca masyarakat Indonesia. Gerakan Literasi Sekolah (GLS) merupakaan salah satu strategi pemerintah dalam meningkatkan kemampuan membaca siswa. Namun, dalam pelaksanaannya GLS tidak berjalan sebagaimana mestinya. Salah satu permasalahannya yaitu dari lingkungan literasi diantaranya belum tersedia sudut buku kelas. Pengembangan sudut buku ini merupakan upaya untuk menumbuhkan minat baca siswa

KAJIAN ANALISIS PEMBELAJARAN KONSTRUKTIVISME MELALUI PENERAPAN MODEL LEARNING CYCLE TERHADAP PEMBENTUKAN KARAKTER BERPIKIR ILMIAH

According to the constructivist view of learning is the process by which scientific knowledge . This formation should be carried out by the students as learners . He must be actively engaged , active thinking , draft and give meaning of the things being studied. Constructivist approach emphasizes that the main role in the learning activities are the activities of students in constructing their own knowledge . One model of learning that can be applied to make the learning experience of students is learning cycle ( cycle study) . Learning cycle model of learning can help students to recall the previous subject matter , and train students learn to find concepts through experimentation . Based on the results of data analysis and discussion of the results , it can be concluded that the use of learning model learning cycle is able to have a significant influence on the formation of the character of scientific thinking of students

Magnetic free energy at elevated temperatures and hysteresis of magnetic particles

We derive a free energy for weakly anisotropic ferromagnets which is valid in the whole temperature range and interpolates between the micromagnetic energy at zero temperature and the Landau free energy near the Curie point T_c. This free energy takes into account the change of the magnetization length due to thermal effects, in particular, in the inhomogeneous states. As an illustration, we study the thermal effect on the Stoner-Wohlfarth curve and hysteresis loop of a ferromagnetic nanoparticle assuming that it is in a single-domain state. Within this model, the saddle point of the particle's free energy, as well as the metastability boundary, are due to the change in the magnetization length sufficiently close to T_c, as opposed to the usual homogeneous rotation process at lower temperatures.Comment: 16 pages, 4 figure
