the green peach aphid,myzuspersicae  (hem:aphididae) is a polyphagus aphid species that infects over 400 plants species belonging to 40 different families. the oenopia conglobata contaminata  (col.: coccinellidae) is one of the most important predator of orchard pests in iran. in this study, efficiency and predatory of this predatoron green peach aphid m.persicaewas evaluated under laboratory c...

The codeword searching sequence is sometimes very vital to the efficiency of a vector quantization (VQ) encoding algorithm. In this paper, we evaluate some necessary criteria for the derivation of an optimal searching sequence and derive the optimal searching sequence based on such criteria.

We describe efficiency improvements made to the DBLEARN program for performing knowledge discovery in databases. The original DBLEARN prototype implementation suffered from relatively poor performance. Causes of this inefficiency are explored and implementation strategies are suggested to improve performance. They include better memory management, more efficient storage of attribute values, and...

Sequence alignment and database searching are essential tools in biology because a protein's function can often be inferred from homologous proteins. Standard sequence comparison methods use substitution matrices to find the alignment with the best sum of similarity scores between aligned residues. These similarity scores do not take the local sequence context into account. Here, we present an ...

Searching for data is one of the fundamental fields of computing. Often, the difference between a fast and slow one is the use of good algorithm for the data set. The efficiency of searching techniques used in a task will determine how fast such task can be completed. In this work, the efficiency of linear and binary searching techniques in terms of running time, memory usage and the numbers of...

When searching for hosts on a plant, female parasitoids use strategies to maximize efficiency. Searching strategies include the expressed behaviors, the time budget associated with each behavior, the time allocated to the different plant parts and the exploration sequence of plant parts. Searching efficiency refers to the time taken to find the first egg, the number of eggs found per foraging t...

Searching for domain-specific information on the web is tough. Community documents are therefore made searchable with a dedicated search platform. Search Methods employed document corpora often evaluated over aspect of efficiency and not focusing often-overlooked user experience. In paper, we present an evaluation methods methods. The represented in RDF as well free-text. We describe environmen...
