Virtual colony count

Simplified method to automatically count bacterial colony forming unit.

Bacterial colony counting is a significant technical hurdle for vaccine studies as well as various microbiological studies. We now show that an automated colony counter can process images obtained with a digital camera or document scanner and that any laboratory can efficiently have bacterial colonies enumerated by sending the images to a laboratory with a colony counter via internet.

The Relationship Between Salivary Candida Albicans Colony Count and Blood Group Antigens in Dentistry Students

Background and Aims: Candida albicans is the most prevalent opportunistic fungal species in the oral cavity. To date, several studies have been investigated the various factors associated with oral candidiasis. On the other hand, it has been proven that blood types antigens lead to some infectious factors. This study aimed to evaluate Candida albicans colonies in the saliva of dentistry student...

Optimal product design using a colony of virtual ants

The optimal product design problem, where the ‘‘best’’ mix of product features are formulated into an ideal offering, is formulated using ant colony optimization (ACO). Here, algorithms based on the behavior of social insects are applied to a consumer decision model designed to guide new product decisions and to allow planning and evaluation of product offering scenarios. ACO heuristics are eff...

A modified ant colony optimization algorithm for virtual network embedding

Traditional Internet architecture is far too rigid for use with large numbers of network applications with different quality of service requirements. One new and promising approach to overcome the rigidity is network virtualization (NV), which allows multiple heterogeneous virtual networks to coexist on a shared substrate network (SN). However, one of the key problems for NV is the virtual netw...
