Warpage and shrinkage control are important factors in proving the quality of thin-wall parts in injection modeling process. In the present paper, grey relational analysis was used in order to optimize these two parameters in manufacturing plastic bush of articulated garden tractor. The material used in the plastic bush is Derlin 500. The input parameters in the process were selected according ...

ISO/TC130 is responsible for international printing standards development. Normative requirements for process control have been centered on solid coloration and TVI. Grey balance and grey reproduction are being addressed in the revision of ISO/WD1 12647-2 (2011). In this regard, the ISO/WD1 12647-2 (2011) takes paper color into consideration when defining grey reproduction aims, but there is a ...

Abstract The stable operation of the aircraft electrical power system is closely related to aircraft’s function implementation and safety. Therefore, research on fault diagnosis important necessary. This paper proposes a method civil based triangular fuzzy number grey relational analysis. For purpose obtaining complete data, it takes into account single symptom historical keeps feature from ini...

Voxel-based morphometry (VBM) is commonly used to study systematic differences in brain morphology from patients with various disorders, usually by comparisons with control subjects. It has often been suggested, however, that VBM is also sensitive to variations in composition in grey matter. The nature of the grey matter changes identified with VBM is still poorly understood. The aim of the cur...

A Grey parrot (Psittacus erithacus) had previously been taught to use English count words ("one" through "sih" [six]) to label sets of one to six individual items (Pepperberg, 1994). He had also been taught to use the same count words to label the Arabic numerals 1 through 6. Without training, he inferred the relationship between the Arabic numerals and the sets of objects (Pepperberg, 2006b). ...

In this paper we present a new algorithm for filtering a grey-level image using as attribute the number of holes of its connected components. Our approach is based on the max-tree data structure, that makes it possible to implement an attribute filtering of the image with linear computational cost. To determine the number of holes, we present a set of diverse pixel patterns. These patterns are ...

Grey systems and interval valued fuzzy sets appear to be similar concepts. This abstract provides a brief introduction to grey systems and compares them to interval valued fuzzy sets. We argue that grey system is similar to an interval fuzzy set, but has different properties. Grey systems focus on the interval range of the system property itself, but interval fuzzy sets consider the fuzzy membe...

In this paper, an efficient algorithm is presented for drawing anti-aliased straight lines for two grey-level case; experimental results show that it is faster than Liu’s algorithm [6]. Specifically, Liu’s algorithm determines the grey-level of one pixel at a time while our algorithm determines the grey-levels of many pixels at the same time. In addition, our results for the two grey-level case...

Thirteen bushbuck, Tragelaphus scriptus, and 13 grey duikers, Sylvicapra grimmia, were culled in the Weza State Forest, Natal, from May 1983-May 1984. The maximum number of worms recovered from a single bushbuck was 393. Of the total number of worms recovered from all the bushbuck, Paracooperia devossi were the most numerous, followed by Ostertagia harrisi, a Cooperia sp. and Haemonchus vegliai...
