The process of evaluating uncertainty associated with a measurement result is often called uncertainty analysis or error analysis. Without proper error analysis, no valid scientific conclusions can be drawn. The uncertainty of a single measurement is limited by the precision and accuracy of the measurement. The errors are communicated in different mathematical operations. Every deviation in result of experiment from the expected one has important significance. Even on undergraduate level of our domestic universities, error analysis and interpretation of the result should be done instead of writing just the points of precautions. This approach will make the students somewhat familiar about the error analysis on advanced level. Otherwise, the hesitation and difficulty about error analysis which stuns M.Sc. level beginner student will persist and the necessity of standardization of our lab reports will remain untouched for next several years also.The Himalayan PhysicsVol. 3, No. 3, July 2012Page: 78-86

Abstract:The micro-machined gyroscope that uses Coriolis force to measure angular velocity has non-linear error,which makes the amplitude of angular velocity have a relationship with its frequency,and fabrication technology error,which leads gyroscope’s drive shaft and detection shaft not to be vertical.All kinds of errors severely restrict this kind of gyroscope’s measuring accuracy and application range.This article obtained the reason for the formation of all kind of gyroscope’s errors and their mathematical expressions through analyzing the principle of micromachined gyroscope,which uses Coriolis force to measure angular velocity.At the same time,the gyroscope mathematical model was established and used to emulate to analyze each error’s influence on the angular velocity measured by gyroscope.The conclusion obtained by theoretical analysis and simulation provides the basis for gyroscope’s error analysis and elimination,and it has an important significance in improving the measuring accuracy of gyroscope.

Globalization demands dynamism in English as a Second Language (ESL) pedagogy to address the needs of students from diverse cultural, educational and linguistic backgrounds. Students hailing from different countries with varied levels of English proficiency present a serious challenge to instructors. The challenge to meet the needs of diverse students from Afghanistan and Pakistan, for instance, within the same teaching faculty, prompted this study. It attempts to explore Afghan and Pakistani students’ expectations of the first module of English introduced at undergraduate level, i.e., English Comprehension and Composition (ECC) at a Pakistani university, by applying the Expectancy Disconfirmation Model of Satisfaction (Oliver 2015,120). Students’ expectations have been a neglected area of research despite being a significant factor in behavior and performance. This study aims to find out how far the Pakistani and Afghan students’ expectations have been met with Negative Disconfirmation (non-fulfillment), Zero Disconfirmation (fulfillment) or Positive Disconfirmation (enhanced fulfillment). The findings reveal that the Afghan students were enrolled in the Pakistani university as a result of a mutual agreement between the Pakistani and Afghan governments under the Higher Education Commission (HEC)scholarship “Award of 3000 Scholarships to Students from Afghanistan under the Prime Minister’s Directive” had concerns with the advanced level grammar and reading exercises, while Pakistani students complained about insufficient class time, consecutive lectures and lack of adequate practice provided in the classroom. The study suggests a pedagogical framework for the students focusing on Contextualized Task Based Language Teaching (CTBLT) method in combination with Input-oriented approach for the desired academic outputmentioned in the objectives of the course/module.

Error Calibration

A 3-DOF simulation turntable with perpendicular errors is introduced. The characteristics of period and variation in the perpendicular error are liable to bring about orientation error, which is a function of the overall static inaccuracy. Aimed to compensate orientation error, a perpendicular error calibration method is proposed to measure the perpendicular error between the axis and the bushing of a rotating axis in simulation turntable. Based on transformation matrix, gesture transformation matrix with various error items is achieved. As a result of this analysis, perpendicular error analysis is carried out when this measurement result is applied to a simulation turntable. Furthermore, this study also permits the user to know how to minimize some error sources of the simulation turntable.

Pengumpulan data menggunakan tes tertulis dan dokumentasi. Analisis data menggunakan analisis deskriptif kualitatif. Dalam analisis ini, kesalahan siswa dikategorikan berdasarkan Newman’s Error Analysis. Hasil penelitian menunjukkan bahwa masih banyak siswa yang melakukan kesalahan dalam menyelesaikan soal cerita program linear. Kesalahan yang paling banyak terjadi adalah kesalahan penulisan jawaban akhir, sedangkan kesalahan yang paling sedikit terjadi adalah kesalahan transformasi. Kesalahan membaca terjadi karena siswa tidak mampu memaknai kalimat dengan tepat dan tidak mampu menemukan kata kunci atau informasi dalam soal. Kesalahan memahami soal terjadi karena siswa keliru dalam menuliskan apa yang diketahui dan ditanyakan dalam soal. Kesalahan transformasi terjadi karena siswa tidak mampu mentransformasikan masalah ke dalam model matematika dan tidak teliti dalam melakukan operasi matematika. Kesalahan keterampilan proses terjadi karena siswa mengalami kesalahan prosedur seperti salah dalam menulis fungsi tujuan yang akan dicapai dan tidak dapat memproses lebih lanjut solusi dari penyelesaian soal. Kesalahan penulisan jawaban terjadi karena banyak siswa yang tidak menuliskan kesimpulan, menuliskan kesimpulan tetapi tidak tepat, serta menuliskan kesimpulan yang salah. Analysis of students' errors in solving word problems of the linear program based on Newman's error analysisAbstractThis study aimed to describe students’ errors in solving word problems of the linear program. This study’s subjects were students of grade-eleventh (n = 30) SMAN 5 (Senior High School) in Serang City, Indonesia. Data collection using written the test and documentation. Data analysis using qualitative descriptive analysis. In this analysis, students' errors were categorized based on Newman's Error Analysis. The results showed that many students made errors in solving word problems of the linear program. The most common error was writing the final answer, while the error that occurs the least was the transformation error. Reading errors occur because students could not interpret sentences correctly and could not found keywords or information in the problems. Errors in understanding the problems occur because students made errors in writing what they know and were asked in the problems. Transformation errors occur because students could not transform problems into mathematical models and were not careful in performing mathematical operations. Process skill errors occur because students experienced procedural errors such as incorrectly writing the objective function to be achieved and could not do the next process to find a solution to the problems. Errors in writing answers occur because many students did not write conclusions, write inaccurate conclusions, and write wrong conclusions.

Considering the importance of grammatical aspect in the writing process, the students should have gramatical knowledge since they are as a beginner. This research aims at error analysis of students’ writing by using surface taxonomy strategy and the factors happen in error of students’ writing based on surface taxonomy strategy at Pre-Planet Program of Kresna English Language. The research study is classified into qualitative research. The instrument that the researcher used are document and interview. By analyzing the students’ answer sheet, the writer obtained their scores of the test result and found that the highest error was found in Misinformation, the students committed 147 times or 68.37% out of the whole errors. The second is Omission, from the data that was found 37 times or 17.21 % out of the whole errors of omission. Then, Addition was found 27 errors or 12.56 % on their writing. The lowest percentage is Mis ordering, was found 4 times or 1.86% errors. The factors of those errors because of the students do not know well about how to use the structure of sentence, the vocabulary that the students do not know before even how to spell it. Writing can begin from a simple piece to a more advanced level of writing. It includes the organization of words, phrases, clauses and sentences.
