Vigour was measured using computer-aided analysis of digital images in six seed lots of Impatiens that differed in vigour but retained greater than 86% standard germination. Seed lots that differed in initial seed vigour were selected based on the commercially used Ball Vigour Index and vigour independently assessed using saturated salts accelerated aging tests. Digital images were captured fro...

In the Gen-2 Q-algorithm, the values of weight C, which is the parameter for incrementing or decrementing the slot-count size, are not optimized in the standard. However, the standard suggests that the reader uses small values of C when the slot-count is large and larger values of C when the slot-count is small. In this case, if the reader selects an inappropriate weight, there are a lot of emp...

Previously, we have studied the minimal oligomer size of an aggregate amyloid seed and the mechanism of seed growth with a multilayer -sheet model. Under high temperature simulation conditions, our approach can test the stability of possible amyloid forms. Here, we report our study of oligomers of Alzheimer’s amyloid -peptide (A ) fragments 16–22, 16–35, and 10–35 (abbreviated A 16–22, A 16–35,...

In this paper, we review the definition of a variant of TCP, called SmoothTCP, and describe one of its versions which uses ICMP-SQ messages as its primary control metric. This version of SmoothTCP is intended to be used in environments subject to spurious errors, such as in wireless networks. We evaluate the behavior of this version of SmoothTCP by comparing it with the behavior of Standard TCP...

Based on image processing technology, the detection, classification and feature extraction for plant grain shape are performed in this paper. Taking rice grain as an example, the shape detection and description method of similar round object are studied firstly. Then a grain shape description method based on 8 feature points of rice grain boundary is proposed. Aiming at rice seed detection, a s...

The effect of seed size on germination and early growth of maize plant, was examined within three weeks to determine the best seed size require for planting. The larger size seed produced significant growth compared to medium size and small size. The seedling height, seedling width, and seedling biomass increased in larger size seed. The significant growth observed in larger size seed showed th...
