The measurement of the Cosmic Microwave Background (CMB) polarization and spectral distortions produced on this radiation field by clusters galaxies (Sunyaev-Zeldovich Effect, SZE) are current frontiers in cosmology. In paper, we report two stratospheric balloon experiments aimed to study research fields mentioned above. OLIMPO is a mm/submm waves telescope, with 2.6 m primary mirror coupled fo...

This paper describes the Oz Explorer and its implementation. The Explorer is a visual constraint programming tool intended to support the development of constraint programs. It uses the search tree of a constraint problem as its central metaphor. Exploration and visualization of the search tree are user-driven and interactive. The constraints of any node in the tree are available first-class: p...

Universal Networking Language (UNL) is a language for computer to represent knowledge and information described in natural languages. Universal Words (UWs) constitute the vocabulary of UNL. The UNL Explorer is a web based application, which combines all the components of UNL system to be accessible online. The users of UNL Explorer are not only researchers and linguists who are interested to wo...
