Multifractional Brownian motion is a Gaussian process which has changing scaling properties generated by varying the local Hölder exponent. We show that multifractional Brownian motion is very sensitive to changes in the selected Hölder exponent and has extreme changes in magnitude. We suggest an alternative stochastic process, called integrated fractional white noise, which retains the important local properties but avoids the undesirable oscillations in magnitude. We also show how the Hölder exponent can be estimated locally from discrete data in this model.

Abstract The use of the J-integral to investigate fracture characterization in a carbon black reinforced natural rubber is described. Three applications to crack initiation are included: two based on the use of a hypothetical zero specimen length and one on conventional testing procedures for metals. While the validity of the zero-length methods is questionable, the conventional method yielded a consistent Jc value of 1.01 N/mm for a typical tire compound. This value was obtained from 24 combinations of varying specimen geometries and pre-crack lengths. The J-integral is revealed as a valid fracture parameter that is applicable not only for material evaluation but also for designing tire structures to resist premature failure. These conclusions disagree with those from an earlier investigation, so the causes for the discrepancies are examined and discussed.

Abstract : Pipetting is one of the most important activities in health laboratory analysis. Knowledge of pipetting must be owned by every health laboratory. Students of health analyst as a candidate of health laboratory who will become medical support service unit is expected to be able to do the pipetting precision and accurately. To get a thorough and accurate results then the results of the analysis must be located within a specifc control area and both in precision and accuracy. Precision and accuracy are responsible for analytical interpretation of test results and testing procedures. The method use in this research is the forward method by 61 people research samples which determined by simple random sampling. While the research design used was observational analytics. Based on the results of the research obtained the level of knowledge of respondents research is 71,38; precision pipetting 99,69% and accuracy pipetting 99,58%. From the data that has been obtained then analyzed statistically using tau kendau test. The result indicates that the level of knowledge and precision has a p=0,640 and correlation coeffcient of -0,044 so that the Ho is accepted, meaning there is no relationship between the level of knowledge and precision meaningful. Meanwhile, the level of knowledge and accuracy of the p=0,574 and correlation coeffcient value is -0,053 so that Ho is accepted, it means there is no relationship between the level of knowledge with accuracy. Abstrak: Pemipetan merupakan salah satu kegiatan yang sangat penting dalam analisa laboratorium kesehatan. Pengetahuan pemipetan harus dimiliki oleh setiap tenaga laboratorium kesehatan. Mahasiswa analis kesehatan sebagai calon tenaga laboratorium kesehatan yang akan menjadi unit pelayanan penunjang medis diharapkan mampu melakukan pemipetan dengan teliti dan akurat. Untuk mendapatkan hasil yang teliti dan akurat maka hasil analisa harus terletak di dalam daerah kontrol tertentu dan baik dalam presisi maupun akurasi. Presisi dan akurasi bertanggung jawab terhadap interpretasi analitik hasil pengujian serta prosedur pengujian. Metode yang dilakukan dalam penelitian ini adalah metode forward oleh sampel penelitian sebanyak 61 orang yang ditentukan secara simple random sampling. Sedangkan desain penelitian yang digunakan adalah observasional analitik. Berdasarkan dari hasil penelitian diperoleh nilai tingkat pengetahuan responden penelitian adalah 71,38; presisi pemipetan 99,69% dan akurasi pemipetannya 99,58%. Dari data yang telah didapatkan kemudian dianalisis secara statistik menggunakan uji kendal tau. Untuk tingkat pengetahuan dengan presisi didapatkan hasil nilai p=0,640 dan koefsien korelasi -0,044 sehingga Ho diterima, berarti tidak ada hubungan antara tingkat pengetahuan dan presisi. Untuk tingkat pengetahuan dengan akurasi nilai p=0,574 dan koefsien korelasi adalah -0,053 sehingga Ho diterima, berarti tidak ada hubungan antara tingkat pengetahuan dengan akurasi.
