Background: The interaction of highly intense laser pulses with solid targets covers a wide range of phenomena over several orders of magnitude in laser intensity. Time-of-flight measurements provide an accurate reconstruction of the ion energy spectra. We report on the observation of aluminium ions from a laser-plasma interaction by a scintillator-based detector with adjustable dynamic range. Methods:...
Uruguay is undertaking a countrywide deployment of the One Laptop per Child (OLPC) initiative, named Plan Ceibal. The technical challenges imposed by this project are both the computing infrastructure, involving the XO laptop distribution to every scholar in addition to the maintenance of a distributed server platform, and wireless communication infrastructure. Rural and semi-rural areas were covered...
During the last years there has been a strong research effort on the autonomic communications and self-management paradigms. Following this impulse, the academic community and the industry have proposed several architectures and techniques to allow network devices to make their own configuration decisions. Those proposals often include resource-expensive technologies such as complex inference machines,...
Rural environments of developing countries usually lack of the appropriate communications infrastructure, accentuating the geographical isolation of rural communities. A cost-efficient and service-oriented deployment of Information and Communications Technologies (ICTs) helps to reduce the so-called "digital divide", improving the productivity and quality of life of those communities. Mobile...
We report on the design of a small animal PET scanner based on continuous LYSO crystals and position sensitive photomultiplier tubes (PSPMTs), together with the first results from the calibration. The scanner consists of eight compact modules forming an octagon and leaving a port of 110 mm aperture. Each module is made out of a continuous LYSO crystal and a PSPMT, and contains its associated electronics...
