Non-invasive functional activation of denervated muscles and assessment of muscle function require novel stimulation and measurement techniques. Stimulation equipment must be safe enough for home-based training though the applied electrical parameters raise critical safety issues. Assessment of biomechanical and electrophysiological parameters is provided by oscillation tonometry, twitch and m-...

This work discusses the invariance of local manipulability indices which are used to convert into a scalar the capability of a robotic device at a given configuration to perform a manipulation task. It is shown that they suffer from non–invariance in the sense that arbitrariness in the choice of the metric functions employed in their definition is unavoidable and they are not invariant under ch...

Measurement, evaluation and analysis are support processes to main engineering processes. In this work we present an integrated strategy whose rationale is supported by a well-defined measurement and evaluation process, a conceptual framework that relies on an ontological base, and quality evaluation methods. Particularly, we discuss some process views for specifying project context, nonfunctio...

Analysis of temporal properties of nonfunctional – i.e., quality – requirements (NFRs) has not received significant attention. In response, this paper introduces basic concepts and techniques needed for the specification and analysis of time properties of NFRs.

Service-Oriented Architectures (SOA) provide a flexible and dynamic platform for implementing business services. Due to the rapid increase in the number of available services, more emphasis is put on their reliability, availability, security, etc. In order to meet such non-functional requirements, a service needs to be designed for reliability by making design decisions on an architectural leve...

A new algorithm for solving non-homogeneous asymptotically linear and superlinear problems is proposed. The ground state solution of the problem, which in general obtained as a mini-max associated functional, minimum functional constrained to Pohozaev manifold instead. Examples are given use this method finding numerical radially symmetric positive solutions depending on various parameters.
