Abstract

This paper proposes a polytopic LPV controller design for air craft lateral-directional dynamics. The state space matrices of the plant and the controller are represented by using polytopic linear parameter varying model. A controller synthesis is derived by an approach linear matrix inequalities evaluated at the 32 vertices of the polytopic model. From the simulation results, it can be show that a polytopic LPV controller can maintain the closed loop systems stability and performance.

Abstract

The purpose of this research is to describe and explain the following things: (1) indirect expressions; (2) heuristics and hermeneutic analysis; (3) matrix, models, and variants; (4) hipograms variable; which are contained in "Surat Cinta" and "Malaikat di Gereja St. Josef", poems written by W. S. Rendra. This is a qualitative research. The data which are used in this research are linguistic aesthetical units, consist of words, phrases, lines, and stanzas in the poems. The data resources are poems written by W. S. Rendra, entitled "Surat Cinta" and "Malaikat di Gereja St. Josef". The research instrument is the researcher himself who provides insight and experience about semiotic theory dealing with the analysis of the poems, especially Riffaterre semiotic theory. The data collecting method which is used in this research is a literature exploration which is conducted by reading and noting techniques. Qualitative is the method which is used to analyze the data, while qualitative descriptive is the conducted technique in term of analyzing the process. The process taken has brought the researcher to the following conclusions. 1) Indirect expressions includes the changing of words’ meaning, for example, /surat cinta/ caused by ambiguity, /bagai berjuta-juta jarum alit/ which is a linguistic term called kias simile or comparison, /tiada lebih buruk dan tiada lebih baik /, / orang yang bermula dari kata kata yang bermula dari kehidupan pikir dan rasa / which are linguistic kias epik simile or parable of the epic. /Engkau adalah putri duyung / is a personification stylistic. The whole part of "Surat cinta" is in allegory stylistic. Putri duyung is a kias sinekdoki. /Kutulis surat ini kala hujan gerimis bagai bunyi tambur/ shows the use of fantasy or imagination overview. The deviations meaning in "surat cinta" are caused by ambiguity, for instance, /surat cinta/, the new meaning of sentences caused by rhyme: an end rhyme, for example /Putri duyung dengan suara merdu lembut bagai angin laut/, straight rhyme, for example /Angin mendesah selalu mendesah/, while /kala langit menangis/ is an example assonance rhyme and /menangis minta mainan/ is an alliteration rhyme. The deviations meaning also can be caused by enjambments, for example, /Dan angin mendesah mengeluh dan mendesah/, and homologs, for example, /orang yang bermula dari kata kata yang bermula dari…/ 2) Heuristics and hermeneutic analysis, 3) Matrix, models, and variants. For example, the matrix of "Malaikat di Gereja St. Josef" describes something that God has planned to humankind which appears with the angel in St. Josef church. The models in that poem are "St. Josef" and "Angel", and those models are described by the following variant: /Malaikat di Gereja St. Josef/. 4) The hipograms of "Surat cinta" are: (a) expansion: “Sajak Putih” (1944) and “Derai-Derai Cemara” (1949) by Chairil Anwar. (b) modification: “Sajak Putih” (1944) by Chairil Anwar. (c) actual: “Lagu Gadis Itali” (1920s) by Sitor Situmorang and “Dalam Gelombang” (1920s) by St. Takdir Alysahbana, whereas the hipograms of "Malaikat di Gereja St. Josef" are: (a) Ekserp: “Turun Kembali” (1937) by Amir Hamzah. (b) Modification: “Panggilan Pagi Minggu” by Y. E. Tatengkeng. (c) Actual: poem “Barangkali” by Amir Hamzah.

Abstract

            The objective of the study is to describe Riffaterre semiotika’s meaning of “Bulan Kuning Sudah Tenggelam” based on: 1) indirect expression, 2) reading of heuristic and hermeutik (retroactive), 3) finding matrix, model, and variant, 4) finding hipogram of ‘Bulan Kuning Sudah Tengeelam” short story. The research data were analyzed by qualitative techique. The source of the data was “Bulan Kuning Sudah Tenggelam” short story by Ahmad Tohari. The population of the data was sentences and paragraphs of an event that contained meaningful sign in “ Bulan Kuning Sudah Tenggelam”. The research instrument was researcher who were armed with the concept of meaningful sign system by semiotic theory. The data collecting method of this study was hermeneutika method and  the data collecting techniques were read, write, and book. For the data analysis techinque, the researcher used descriptive qualitative and descriptive analysis method. The results of this research were: 1) the indirect expression consisted of (a) change of meaning, such as kiri-kanan (metomini) replaced by neighbour (b) deviation meaning, such as Oh that was a deviation meaning of admiration, apologetic, wonder, and understanding (c) the creation of meaning, such as //Apabila//, //Apabila//, //Apabila//, //Apabila// that was ended by same vocal //a// //a// //a// 2) reading of heuristic could be found by explicit and reading by hermeneutik could be found by implicit 3) the matrix was rebellion: the model was moon: the variants were the main problems in the story 4) the hipogram was Roman Bumi Manusia novel by Pramoedya Ananta Toer.

Abstract

The principle_work of polyvascular clepsydra water clocks is to make the constant flow on the last vessel. A viscosity dominated case can influence a liquid flow in this clepsydra, beside the number of the vessel which build this clepsydra, will influence a constant flow duration. The increasing the number of the vessel will increase the duration of the constant flow. A case study at PT Tirta Sidatama  is given toverify the principle_work of this clepsydra.

Abstract

Many real problems can be represented in the form of multiple linear regression equation. One of those is the relationship between the variables of temperature and altitude of the spontaneous-potential. In order to determine the parameters of the regression equation, the least squares method was used. From here, there was obtained the system of linear equations. In this paper, to solve systems of linear equations, the exact method was used as the exact solution is certainly better than the approached solution. The method used was the QR factorization method. At the QR factorization, the system of linear equations was written in form of matrix equation. Then, the coefficient matrix which the number of rows is m and number of columns is n with linearly independent columns was factored into the matrix Q which has the same size with the matrix A, with orthonormal columns and matrix R was upper triangular. Furthermore, by backward substitution, it could be obtained the exact solution of linear equation system. As verification of this proposed method, a case study was given using data of temperature, altitude, and spontaneous-potential in the geothermal manifestations area, Gedongsongo, Mount Ungaran Semarang. From here, it was obtained the parameters of exact multiple linear regression model which states the relationship between temperature and altitude toward the spontaneous-potential.
