A set of N-heteroquinones, deriving from oligoacenes, have been recently proposed as n-type organic semiconductors with high electron mobilities in thin-film transistors. Generally speaking, this class of compounds self-assembles in neighboring π-stacks linked by weak hydrogen bonds. We aim at…

Robotics is an emerging field with great activity. Robotics is a field that presents several problems because it depends on a large number of disciplines, technologies, devices and tasks. Its expansion from perfectly controlled industrial environments toward open and dynamic…

Problems encountered in the description of ion-induced compositional changes in non-monatomic solids, on the basis of the binary collision approach (BCA), are reported. The ingredients of a collisional model responsible for eventual ambiguity of computer simulation results are pointed out.…

Most sports are attractive because they are almost unpredictable. The more the competitiveness of league teams, the harder to predict the games and as a result, that league will be more attractive. Competitive balance refers to the balance in sport…

Silver halide sensitized gelatin (SHSG) is one of the most promising techniques for the fabrication of transmission holographic optical elements, achieving relatively high sensitivity of photographic material with the low scattering and high light stability of dichromated gelatin. In this…

Numerical calculation of Fresnel patterns through fast Fourier transforms usually requires an extremely large number of samples in order to fulfil the Nyquist sampling condition. In many applications, the cut-off frequency of the system is much below the limit fixed…

Technological innovation requires a technical preparation in material, financial and human resources. However, without a clear corporate culture, the technical side of technological innovation will hardly develop in a satisfactory manner.
In this light, we analyze the origin of a…

The research presented in this paper approaches the issue of indoor localization using the fuzzy logic framework for modeling and dealing with the uncertainty of the position measurements. Fuzzy logic presents properties that make it suitable tool to represent and…

The purpose of this pilot study was to develop and examine the psychometric properties of the Diabetic Care Teacher Support Questionnaire, a 31-item self-report instrument to assess diabetic children’s perceptions of the diabetes specific support received from their teachers at…

The main step in the production of carbon nanofilaments is the catalytic nucleation and lengthening of the filament. An undesired parallel step in
the production of carbon nanofilaments is their thickening by pyrolitic carbon vapor deposition consisting in an ordered…
