STUDY OF ERROR ESTABLISHMENT IN MILLING MACHINES WITH 5 AXES

This report examines the accuracy of rotary die processing on a 5 axes machine and a special bolt-disk system. Faults that affect the accuracy and their measurement and reduction within acceptable limits are analyzed. As a result of the measurement, a virtual model of the radial beating of the workpiece relative to the actual axis of rotation of the machine was developed

An Automatic System to Discriminate Malignant from Benign Massive Lesions on Mammograms

Mammography is widely recognized as the most reliable technique for early detection of breast cancers. Automated or semi-automated computerized classification schemes can be very useful in assisting radiologists with a second opinion about the visual diagnosis of breast lesions, thus leading to a reduction in the number of unnecessary biopsies. We present a computer-aided diagnosis (CADi) system for the characterization of massive lesions in mammograms, whose aim is to distinguish malignant from benign masses. The CADi system we realized is based on a three-stage algorithm: a) a segmentation technique extracts the contours of the massive lesion from the image; b) sixteen features based on size and shape of the lesion are computed; c) a neural classifier merges the features into an estimated likelihood of malignancy. A dataset of 226 massive lesions (109 malignant and 117 benign) has been used in this study. The system performances have been evaluated terms of the receiver-operating characteristic (ROC) analysis, obtaining A_z = 0.80+-0.04 as the estimated area under the ROC curve.Comment: 6 pages, 3 figures; Proceedings of the ITBS 2005, 3rd International Conference on Imaging Technologies in Biomedical Sciences, 25-28 September 2005, Milos Island, Greec

Use of the finite element method in studying the influence of different layers on mechanical characteristics of corrugated paperboard

Rebrasti karton se sve više traži ne samo za proizvodnju različitih pakovanja već i za izradu promidžbenih materijala, umjetničkih djela, pribora pri prijevozu skladišne robe i mnogo drugih stvari. S porastom potražnje za rebrastim kartonom javlja se i potreba detaljnijeg poznavanja njegovih mehaničkih svojstava kako bi se poboljšala kvaliteta i pouzdanost finalnih proizvoda. Korišten je model zasnovan na metodi konačnih elemenata te su analizirana mehanička svojstva slojeva rebrastog kartona i njihov utjecaj na njegova ukupna mehanička svojstva.The corrugated paperboard has become a widely used material not only for producing different packages but also for making advertising materials, pieces of art, accessories used for transportation of a number of stock items and many others. With the growing demand for corrugated paperboard comes the need for more detailed knowledge about its mechanical characteristics which would serve for improving the quality and reliability of final products. A model based on the finite element method is used to study how the mechanical characteristics of the layers of the corrugated paperboard affect its complex mechanical characteristics
