In recent years, the topic of desertification has been discussed in different ways in scientific areas. This event occurred globally, regionally and nationally and many steps were taken to stop it. Desertification is challenged universally and its destructive effects are unavoidable and its consequences do endanger the life of inhabitants. The identification of sensitive regions and prevention ...

predicting the effort of a successful project has been a major problem for software engineers the significance of which has led to extensive investigation in this area. One of the main objectives of software engineering society is the development of useful models to predict the costs of software product development. The absence of these activities before starting the project will lead to variou...

We consider two families of commuting Hamiltonians on the cotangent bundle of the group GL(n, C), and show that upon an appropriate single symplectic reduction they descend to the spectral invariants of the hyperbolic Sutherland and of the rational Ruijsenaars-Schneider Lax matrices, respectively. The duality symplectomorphism between these two integrable models, that was constructed by Ruijsen...

In this note, we give an effective description of the tensor product k[[X]] ⊗k k[[Y ]]. This latter ring is well known to be not isomorphic to k[[X,Y ]]. The effective description we provide is given through the identification of k[[X,Y ]] with a convolution algebra. As an application, we prove that the group structure of Ak does not descend to Spec k[[X]]. Mathematics Subject Classification: 1...

In this paper we introduce an approach to integrate heterogeneous structured data into a learning vector quantization. The total distance between two heterogeneous structured samples is defined as a weighted sum of the distances in the single structural components. The weights are adapted in every iteration of learning using gradient descend on the cost function inspired by Generalized Learning...

Retractile testes [1] Prepubertal boys can have an exaggerated cremasteric reflex. The testis may retract out of the scrotum in the cold, on examination, on excitement or on physical activity. It is normal and will descend when relaxed and warm, or it can be manipulated back into the scrotum. Retractile testes do not need any treatment but do need close follow-up until puberty, as they can beco...
