Clusters are useful to identify required object from the huge amount of datasets. There are lots of clustering methods, used to create clusters. Single linkage clustering method is an example of hierarchical agglomerative clustering which is used to merge objects in a cluster, based on minimum distance. In this paper we performed an experiment on two dimensional spaces where multiple objects ar...

We propose a hierarchical, unsupervised clustering algorithm (TreeGCS) based upon the Growing Cell Structure (GCS) neural network of Fritzke. Our algorithm improves an inconsistency in the GCS algorithm, where the network topology is susceptible to the ordering of the input vectors. We demonstrate improved stability of the GCS foundation by alternating the input vector order on each presentatio...

Differences were detected in the gene expression of strains of E. histolytica using RNA (RAP-PCR) and DNA fingerprinting (RAPD). Analysis of the electrophoretic profiles of the gels revealed some polymorphic markers that could be used in the individual characterization of the strains. The 260 bands generated by using five different primers for RAP-PCR, as well as RAPD, were employed in the cons...

Turkey is very rich in local grape varieties. The solution to the problem of identifying local cultivars, which is considered an important deficiency for the region, will only be possible when they can be defined with molecular markers. Forty-nine local grapevine cultivars from Şanlıurfa (Turkey) were characterized with RAPD markers. Twenty-five decamer primers selected from 60 primers were use...

The task of developing and improving intelligent multi-agent control systems, which provide opportunities for online analysis the electrical power supply system provided by smart grid system, is considered. purpose article formation clusters sections network, initial parameters are main indicators quality energy in accordance with accepted standards. Total harmonic distortion coefficient voltag...

Mer protein has not been classified beyond the scope of its signaling activity. In this paper, the entire Mer protein sequences have been quantified, and a set of clusters have been made to explore the similar behaviors of Mer protein in a quantitative manner. Previous studies have established that Mer proteins have an important role in cancer biology, so for identifying potential strategies it...

The genetic divergence of 65 strains of Bacillus thuringiensis (Bt) was determined using Rep-PCR. Based on the repetitive sequences the BOX primer was the most informative with 26 fragments, followed by ERIC (19) and REP (10), generating a total of 55 fragments. The dendogram shows that ten groups were formed when 45% was the average distance of the population: group 1 with 41,5% of the isolate...

Fulani ecotype chickens (FEC) and Yoruba ecotype chickens (YEC) are the two major types of indigenous chickens in Nigeria. They subsist under traditional Animal husbandry and are thus liable to indiscriminate mating and consequently to loss of genetic diversity. Fulani ecotype chickens (FEC) and Yoruba ecotype chickens (YEC) were investigated to determine genetic variation at transferrin locus ...

Most of the techniques used in the literature for hierarchical clustering are based on o€-line operation. The main contribution of this paper is to propose a new algorithm for on-line hierarchical clustering by ®nding the nearest k objects to each introduced object so far and these nearest k objects are continuously updated by the arrival of a new object. By ®nal object, we have the objects and...
