In this paper, we develop a method to construct non-redundant directional wavelet filter banks. Our method uses a special class of filters called Neville filters and can construct non-redundant wavelet filter banks in any dimension for any dilation matrix. The resulting filter banks have directional analysis highpass filters, thus can be used in extracting directional contents in multi-D signal...

INTRODUCTION Bisphosphonates (BPs) can be locally used to improve the osteogenesis around hydroxyapatite (HA) implants. However, there are almost no reports discussing the effects of BPs in the bonding state with HA on bone mesenchymal stromal cells (BMSCs). Clodronate is a BP widely used in clinical practice. This study was designed to evaluate the effects of clodronate combined with HA on BMS...

Editorial Forging Ahead 'All I know,' wrote Seamus Heaney, 'is a door into the dark 1 .' Me too. The world of radiology is figuratively and perhaps, on occasion, literally just that. Our game is the image, not the written word. Pretty pictures. Yet, now we increasingly find ourselves integral to the medical paradigm. This, clearly, is no reflection on us, but underpins the requirement, primacy,...

This paper proposes a robust method for directional field estimation from fingerprint images that combines estimates at multiple scales. The method is able to provide accurate estimates in scratchy regions, while at the same time maintaining correct estimates around singular points. Compared to other methods, the penalty for detecting false singular points is much smaller, because this does not...

The main body of primary system valves discussed in this paper is made of stabilized austenitic stainless steel and are of intricate shapes & sizes. These bodies are produced through close die forging route and are manufactured first time in Indian forging shops. Finished forgings produced through three stage close die forging process are subjected to comprehensive quality assurance plan at eac...

Abstract— Forging is a very complex process and the measurement of actual forces for real material is difficult and cumbersome. The main objective of this document is to use the analytical methods for measuring parameters such as load, and stress distribution of forging process and use them to make simple, reliable, fast and non-expensive simulation tools, contrary to the commercial software’s ...
