A fuzzy multipurpose decision making problem, where the information about the alternatives provided by the experts can be presented by means of diierent preference representation structures, is studied. Assuming that the information can be represented by means of preference orderings, utility functions and fuzzy preference relations, a general multipurpose decision making model is managed to co...

Environmentally friendly multipurpose grease formulation has been synthesized by using Jatropha vegetable residual oil with lithium soap and multifunctional additive. The thus obtained formulation was evaluated for its tribological performance on a four-ball tribo-tester. The anti-friction and anti-wear performance characteristics were evaluated using standard test methods. The biodegradability...

Supporting human actors in daily living activities for improving health and wellbeing is a fundamental goal for assistive technology. The personalization of the support provided by assistive technology in the form of digital coaching requires user models that handle potentially conflicting goals and motives. The aim of this research is to extend a motivational model implemented in an assistive ...

We present the iterative design and evolution of a web-based screen management middleware developed for a network of interactive multipurpose public displays deployed in a city center since 2009. Themiddleware provides three principal user interface abstractions to content producers, application developers and display owners: the classical passive digital signage, a portal of interactive applic...

We propose a novel multipurpose watermarking scheme, in which robust and fragile watermarks are simultaneously embedded, for copyright protection and content authentication. By quantizing a host image's wavelet coefficients as masking threshold units (MTUs), two complementary watermarks are embedded using cocktail watermarking and they can be blindly extracted without access to the host image. ...

The authors have been concentrating on developing a convenient 3D measurement method using consumer grade digital cameras, and software “3DiVision” has been designed to perform convenient 3D measurements under the key words; 3Dimension, Digital image and Visualization. “3DiVision” has shown the capability to compute both exterior and interior orientation parameters simultaneously without GCP on...

In this study, a novel multipurpose portable PEM fuel cell-solar-battery system was custom designed, constructed and laboratory tested, specially aims for applications in the rural areas remote from conventional electric power grid. We obtain encouraging results which show the applicability of such system for used as a multipurpose kit for portable applications. Our study shows that various pow...

A novel generic method of silica supported catalyst system generation from a fluid state is presented. The technique is based on the combined flow and radiation (such as microwave, thermal or UV) induced co-assembly of the support and catalyst precursors forming nano-reactors, followed by catalyst precursor decomposition. The transformation from the precursor to supported catalyst oxide state c...
