فعالیت های نگهداری و تعمیرات اطلاعاتی را تولید می کند که می تواند در تعیین زمان های بیکاری و ارایه یک برنامه زمان بندی شده یا تعیین هشدارهای خرابی به پرسنل نگهداری و تعمیرات کمک کند. وقتی که مقدار داده های تولید شده زیاد باشند، فهم بین متغیرها بسیار مشکل می شوند. این پایان نامه به کاربردی از داده کاوی برای کاوش پایگاه های داده چندبعدی در حوزه نگهداری و تعمیرات، برای پیدا کردن خرابی هایی که موجب...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
Data preparation is a significant preprocessing task to prepare data for mining. The data mining process cannot succeed without a serious effort to prepare data. Very often mistakes are found in data, thus making the analysis process more difficult. Without the data preparation phase, we will have no idea whether the data quality can support analysis queries. Several techniques exist for data p...
We report on the characterization of the NUV-HD SiPMs developed at FBK at cryogenic temperature. A dedicated setup was built to measure the primary dark noise and correlated noises of the SiPMs between 40 and 300 K. Moreover a specific analysis program in conjunction with an ad-hoc data acquisition system were developed to allow the precise characterization of these parameters, some of which ca...

This paper uses the concept of characterized model for bivariate extensions of univariate life distributions based on mean residual life properties. Different bivariate distributions can be generated from different choices of marginal distributions. The retention of univariate IMRL, DMRL, NBUE, NWUE, HNBUE and HNWUE class properties in the bivariate setup has been ensured along with results of ...
Aim. The paper aims to overview the opportunities, approaches and techniques of studying ensuring functional safety transportation systems, including those driverless, with use Big Data. It is noted, that modern technology underpins next-generation systems operate in ever-evolving conditions, significant numbers passengers, requires modified control design. With growth agglomerations, many subu...
