In this paper the letter segmentation of photographs was used, taken from a Parrot AR Drone’s camera with the aim of establishing a stimulusresponse, where the original picture formed by Red, Green and Blue (RGB) colors was segmented by color (choosing the red channel). Once the character is recognized, the Drone executes the corresponding action. Noise-free number patterns were initially used ...

In this paper, the problem of drum playing technique detection in polyphonic mixtures of music is addressed. We focus on the identification of 4 rudimentary techniques: strike, buzz roll, flam, and drag. The specifics and the challenges of this task are being discussed, and different sets of features are compared, including various features extracted from NMF-based activation functions, as well...

objective: fragile x syndrome is the second etiology for inherited mental retardation. it may concomitant with other psychiatric disorders. intellectual disability (id) is a state of functioning that typically begins in childhood and is characterized by limitations in intelligence and adaptive skills. we intend to introduce a male young patient with fragile x syndrome and obsessive-compulsive d...

Architectural tactics are design decisions intended to improve some system quality factor. Since their initial formulation, they have been formalized, compared with patterns and associated to styles. However, the initial set of tactics for security has only been refined once. We have examined the tactics set and classification from the viewpoint of security research, and concluded that some tac...

Many techniques in the evolutionary-computing and artificiallife fields have been applied to generating musical phrases. Recently, artificial chemistries, which are virtual models of chemical systems, have come into use for the purpose. In this paper, we attempt to produce polyphonic phrases using an artificial chemistry. The molecules and chemical equations are so designed as to implement a ba...

service oriented enterprises (soes) are subject to constant change and variation. in this paper, the changes are considered from an economic perspective based on service culture notion. once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. we construct a game theoretic model trying to capture the possible conflicting i...
