Optimal regulation in systems with stochastic time sampling

An optimal control theory that accounts for stochastic variable time sampling in a distributed microprocessor based flight control system is presented. The theory is developed by using a linear process model for the airplane dynamics and the information distribution process is modeled as a variable time increment process where, at the time that information is supplied to the control effectors, the control effectors know the time of the next information update only in a stochastic sense. An optimal control problem is formulated and solved for the control law that minimizes the expected value of a quadratic cost function. The optimal cost obtained with a variable time increment Markov information update process where the control effectors know only the past information update intervals and the Markov transition mechanism is almost identical to that obtained with a known and uniform information update interval

THE EFFECT OF TEACHER COMPETENCY AND JOB SATISFACTION ON PRIMARY SCHOOL TEACHER PERFORMANCE

ABSTRACT: The purposes of this research are: 1) to know the influence of the teacher’s competence towards to teacher’s performance, 2) to know the influence of the job satisfaction towards to teacher’s performance, 3) to know the influence of teacher's competence and job satisfaction towards to teacher’s performance. The researcher use quantitative descriptive method. This research has two independent variable, these are: variable X1 (teacher’s competence), X2 (job satisfaction), and a dependent variable Y (teacher’s performance). While the sampling technique, this research using proporsional random sampling. The results of this research are: 1) there is a positive and significant influence partially of the teacher’s preved performance. preved the value of nilai tvalue (5,023) > ttable (1,960) and pvalue (sig. = 0,000) ttable (1,960) and pvalue (sig. = 0,000) Ftable (3,000) and pvalue (sig. = 0,000) Keywords: Competence, Job satisfaction of teachers, Teachers ' Performance

The Correlation Between Phonological Knowledge and Pronunciation Ability

The purpose of this research is to know whether there is a significant correlation between phonological knowledge and pronunciation ability. The method used in this research is correlation design. Variable X is the students’ phonological knowledge and variable Y is students’ pronunciation ability. Population of this research is all of the fourth semester students. There are 80 students as population and the writer took 20 students as the sample.  The data are analyzed using Pearson Product Moment formula to know whether there is a correlation between phonological knowledge and pronunciation ability of the students. The result showed there is a correlation between phonological knowledge and pronunciation ability of the students. Based on the calculation that is obtained, rxy value from variable X and Y is 0,223. It is categorized as a low correlation. Whereas the result of the calculation use tcount formula. The tcount value is 1,002. It means that there is no a significant correlation between X and Y variable.

Analisis Sikap Konsumen terhadap Bauran Pemasaran Jasa Kurir Pos Indonesia dan Pengaruhnya terhadap Loyalitas Konsumen

With the passage of Law 38 of 2009 on the abolition of the monopoly market by Pos Indonesia, making competition in the courier service industry is getting tougher. Pos Indonesia to be able to excel in competition, it is necessary to know the position Pos Indonesia in competition with the main competitor Tiki and JNE according to the views or attitudes of consumers towards variable or attribute that is attached to the courier service. In addition to looking at the situation outside the company, Pos Indonesia to maintain its own consumers need to know the variables that influence customer loyalty.By using descriptive statistical analysis found the largest consumer evaluation value in a variable product , process , and price . While the gap analysis obtained by these three variables is also a weakness of Pos Indonesia . With the model of Fishbein Attitude , attitude consumer value obtained Pos Indonesia at 169.75 with a prominent variable in the variable pace , consumer attitudes Tiki value of 159.83 with the advantages of the process variable , while the value of attitude konsuemn JNE is 171.81, with the variabl prominent products is variable . Further analysis using a statistical causal with multiple linear regression , hypothesis testing based on the results of the F test shows that the marketing mix 7P Pos Indonesia attached to a linear effect on consumer loyalty to the values of determination coefficient of 0.488. While the t-test result that there are no independent variables that significantly affect customer loyalt

Analisis Penggunaan Z-score Altman Untuk Memprediksi Tingkat Kebangkrutan Pada Industri Telekomunikasi Di Bursa Efek Indonesia Periode 2007-2010.

The Background of this research is to know and to analize prediction of company bankruptcy of Telecommunication Industry in BEI periods 2007-2010 which focuses object are four companies which have all criteria in analysis by method Z-score Altman. As we know, the goal of company is not being bankrupt so that the company needed a method to predict the bankruptcy as soon as possible. One of the method is Z-Score Altman, this method used to analize financial statements. Goal this research is to know the potential of bankruptcy, rate of bankruptcy, and insolvensy ranking of Telecommunication Industry in BEI periods 2007-2010.Four companies taken as object is PT. XL Axiata, Tbk (eks PT. Excelcomindo, Tbk), PT. Mobile-8 Telecom, Tbk, PT. Indosat, Tbk and PT. Telekomunikasi Indonesia (PERSERO), Tbk is analyze by using financial statements taken away from by the year 2007 to 2010. After that calculated values of variable x1 to variable x5 and next calculated the value of each variable into Altman's Formula to produce the score ( Z-Score). Determining the Z-Score with this categories :a) Z-Score 2,90 are on non bankruptcy compan
