Stabilization and tracking control of an x-z type inverted pendulum system using Lightning Search Algorithm tuned nonlinear PID controller
No full textInverted pendulum systems (IPSs) are mostly used to demonstrate the control rules for keeping the pendulum at a balanced upright position due to a slight force applied to the cart system. This paper presents an application for nonlinear control of an x-z type IPS by using a proportional-integral-derivative (PID) controller with newly established evolutionary tuning method Lightning Search Algorithm (LSA). A single, double and triple PID controller system is tested with the conventional and the self-tuning controllers to get a better understanding of the performance of the given system. The mathematical modelling of the x-z type IPS, the theoretical explanation of the LSA and the simulation analysis of the x-z type IPS is put forward entirely. The LSA algorithm solves the optimization problem of PID controller in an evolutionary way. The most effective way of making comparisons is evaluating the performance results with a well-known optimization technique or with the previous accepted results. We have compared the system's performance with particle swarm optimization and with a classical control study in the literature. According to the simulation results, LSA-tuned PID controller has the ability to decrease the overshoot better than the conventional-tuned controllers. Finally, it can be concluded that the LSA-supported PID can better stabilize the pendulum angle and track the reference better for non-disturbed and the slightly disturbed systems
The Determınatıon of the Mats Used in Drıver's Seat Vıbratıon Effects on Agrıcultural Tractors
No full textIn this study, vibrations that occured on the tractor driver’s seat have been measured by experimental method. While driving the tractor on the land, the degree of vibration has been measured with a real driver. In the study, three cushions made by different materials have been used on the seat. Together with the no cushion condition, four different values have been taken. The cushions are made of wool, sponge and cotton. With HVM100 device, vibration values were recorded for each cushion in a period of 60 seconds on different terrain conditions and then, recorded values were transferred to computer. Those information were transformed into graphic with Blaze software program. Displacement and acceleration graphs were obtained. By using standard deviation, coefficent of varition and aritmetic average methods, information about the degree of vibration were reached to interpret the graphs. In vibration insulation, there appeared a range of wool, cotton, sponge and the no cushion condition . The driver seat with no cushion has a weaker insulation when compared with the driver seats with cushion. Data obtained from experiments are suitable for ISO 2631 standard and scientific studies. In addition, friction was observed on the mechanism of driver seat during the movement.Bu çalışmada, traktör sürücü koltukları üzerinde oluşan titreşimler deneysel metotla ölçülmüştür. Traktörün arazide çalışması sırasında gerçek sürücü kullanılarak titreşim büyüklüleri ölçülmüştür. Çalışmada oturak üzerinde üç farklı malzemeden yapılmış minder kullanılmıştır. Mindersiz durumla birlikte dört farlı titreşim değerleri alınmıştır. Kullanılan minderler yün, sünger ve pamuktur. Titreşim değerleri HVM100 cihazı ile her minder için farklı arazi şartlarında 60 saniye süre ile kaydedilmiş daha sonra bilgisayar ortamına aktarılmıştır. Blaze programı ile elde edilen veriler üzerinden yer değiştirme ve ivme grafikleri oluşturulmuştur. Grafiklerin anlaşılması için istatiksel metotlardan standart sapma, varyasyon katsayı ve aritmetik ortalama kullanılarak titreşim büyüklüğü hakkında bilgilere ulaşılmıştır. Titreşim yalıtımında, yün, pamuk, sünger ve mindersiz şeklinde bir sıralama meydana gelmiştir. Mindersiz sürücü oturağı ise minderlere göre daha zayıf bir yalıtıma sahiptir. Deney sonucunda elde edilen veri değerleri ISO 2631 standardının belirttiği aralıkta çıkmıştır. Ayrıca yer değiştirme grafiklerden sürücü koltuğunun mekanizmasında hareket sırasında bir sürtünmenin olduğu görülmüştür

Bernard Pannagl's musa panagaea
No full textBernard Pannag1 (1666-1734, from 1684 member of Societas Jesu) was a gymnaSIUm teacher, predicator and 1ibrarian in the C1ementinum college in Prague. On1y five books of him are known, all of them in latin. One of these is Musa panagaea (edited probab1y in J anuary 1729), a collection of his schoo1 dramatic works. We bring an edition of the first part of the Musa panagaea, name1y the p1ays Joannes Nepomucenus, Divus Joannes Baptista and Romulus, with an introduction to the latin schoo1 drama in the 17. and 18. century and with informations about the author. There are no standard rules for the editions of the latin texts from 17. and 18. century, just some recommendations. The interpunction of that age in Bohemia hasn't been described and explained in detail s yet, and iťs different from the interpunction, which is used in the czech language (and in the enghsh as well) today; in our edition we use the czech modem interpunction so as the text can be easily read by modem readers. In the transcription of the words we respect the specific aspects of the modem latin (as we know especially from the works of Bohuslav Balbín) and we don't rewrite them in the c1assical latin way. Using of accents in the Musa panagaea is regular and we describe some rules, which we respect in the transcription of the text, but these..
Musa Dah i bliżej. Zaczynając od powieści Franza Werfla.
No full textThe subject of the first part of the article is an interpretation of Franz Werfel’s novel Forty days of Musa Dah, published in 1933 and containing in its the name of the place where five thousand Armenians made a stand against the Turks in September and October 1915. The book made the author a national hero of the Armenians. However, this Jewish writer simultaneously sensed the approaching Shoah. Hence, in the second part of the paper, I show how the novel grew in importance during World War II: Musa Dah was compared to the resistance in the Jewish ghettos (e.g. the situation of the population in Bialystok). Janusz Korczak was to discuss the novel in the summer of 1941, also the chronicler of the Warsaw Ghetto, Emmanuel Ringelblum, in June 25, 1942 compared the Warsaw Ghetto to Musa Dah.The subject of the first part of the article is an interpretation of Franz Werfel’s novel Forty days of Musa Dah, published in 1933 and containing in its the name of the place where five thousand Armenians made a stand against the Turks in September and October 1915.

The story of Musa and Khidir in QS. al-Kahfi (18): 60-82 according to Al-Alusi’s perspective
No full textAl-Qur’an contains much of deep messages, like in Q.S al-Kahfi 18:60-82. It told about the story Musa and Khidir’s journey, by using descriptive-analitic method. In this thesis the author have two problem formulations are: 1) How is the story Musa and Khidir in Q.S al-Kahfi: 60-82 according to Tafsir Al-Alusi perspective? 2) What is the relevance of story Musa and Khidir in Q.S al-Kahfi: 60-82 towards learning ethics?
Based on the problem formulation above, the author used two ways to analyze the data First, the author will inventory the verses related to the story of Musa and Khidir , namely Surat al-Kahf: 60-82, then interpret the verses using the perspective of the Tafsīr al-Alusi book in a descriptive-analytic manner so that it can be found out how the construction of the interpretations of these verses is actually comprehensive. Second, from al-alusi interpretation, we will know what is the message from the story. Then from the messages of the story, the author try to seek what is the relevance from the story between the ethic of a student with his teacher.
Based on the method of research above, the author concluds that the story of Musa and Khidir contains three hikmah are Having A Big Enthuasiasm In Learning, Be Polite And Tawadhu' To The Teacher And Having A Patience And Commitment To Learning

Using hydraulic oscillator of Banu Musa for teaching relaxation oscillation
No full textOne of the introductory examples of scientific books and articles on relaxation oscillations is description of a tank containing a liquid and a siphon, which is known as Tantalus Cup. In this article, the author has shown that the origin of the cup can not be found in historical documents, and probably from the late eighteenth and early nineteenth centuries this device has appeared in laboratory and educational centers in Europe as teaching instrument. However, the thirty-second design of Alheyalbook of Banu Musa actually defines the means with the same performance but more completely than Tantalus Cup. In this article, this device is called "hydraulic relaxation oscillator of Banu Musa". First the history of the book and the life of author, Ahmad ibn Musa ibn Shaker Khorasani, is briefly stated. Thereafter, the historical and scientific record of Tantalus Cup is studied and the performance of the Cup is also described. Finally, Banu Musa's hydraulic oscillator based on relaxation is described in detail. The article claims that Banu Musa was the first engineer who used the relaxation oscillator in a mechanical device
