One of the main problems when working with electronic noses is the lack of reproducibility or repeatability of the sensor response, so that, if this problem is not properly considered, electronic noses can be useless, especially for quantitative analyses. On the other hand, irreproducibility is increased with portable and low cost electronic noses where laboratory equipment like gas zero genera...

Energy harvesting has become an increasingly important topic thanks to the advantages in renewability and environmental friendliness. In this paper, a comprehensive study on contemporary portable wind energy harvesters has been conducted. The electrical power generation methods of portable wind energy harvesters are surveyed in three major groups, piezoelectric-, electromagnetic-, and electrost...

background: 99mtc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from mo-99/tc-99m generators. usually the generators are either supplied by the iran atomic energy agency or by private companies from foreign countries. in this study we have measured 99mo contamination in 99mtc elute from different generators in a period of one year. materials and methods:...

We present a high efficiency source of picosecond pulses derived from dual cavity optical frequency comb generator. This approach overcomes the limitations single generators that are restricted to efficiencies few percent. achieve with GHz repetition rates offering over hundred times higher output than design and demonstrate tuning pulse width by varying modulation depth intra-cavity electro-op...

GuiGen is a comprehensive set of tools for creating customized graphical user interfaces (GUIs). I t draws from the concept of computing portals, which are here seen as interfaces to application-specific computing services for user communities. While GuiGen was originally designed for the use in computational grids, i t can be used in client/server environments as well. Compared to other GUI ge...

We describe L-FLAT, a Logtalk Toolkit for teaching Formal Languages and Automata Theory. L-FLAT supports the definition of alphabets, the definition of orders over alphabet symbols, the partial definition of languages using unit tests, and the definition of mechanisms, which implement language generators or language recognizers. Supported mechanisms include predicates, regular expressions, fini...

The processing applications that are now being used in mobile and embedded platforms require at the same time a fair amount of processing power and a high level of flexibility, due to the nature of the data to process. In this context we propose a lightweight code generation technique that is able to perform data dependent optimizations at run-time for processing kernels. In this paper we prese...

DC lOO%-steam plasma characteristics were investigated for the application of halogenated hydrocarbon decomposition because steam plasmas are chemically reactive. However, plasma system generally requires complex subsystems such as steam generators and cooling units. The presented steam plasma system is a portable light-weight plasma generation system that does not require any gas supply unit. ...

This paper presents the design pow for a Superscalar VLIWmicroprocessorusing the 0.8 p CMOS portable ASIC library developed in the framework of the ESPRIT2 IDPS project. A ful l set of cell libraries and macro-block generators have been used, in order to achieve fast design cycle, and still maintains a high level of integration and performance. The final circuit contains about875 000 transistor...
