This paper presents a modular framework for design of image based visual servo control for fully actuated dynamic mechanical systems. The approach taken uses the formalism of port Hamiltonian systems to track energy exchanged between the mechanical system and virtual potentials or Hamiltonians associated with each image feature. Asymptotic stability of the system is guaranteed by injecting damp...

At the University of Missouri-Rolla, a novel product architecture design method was utilized to create new designs and prototypes of an intelligent battlefield hazard marking system for the United States Army. This design project was initiated by the Army to improve the current marking system in use worldwide. Designs and prototypes were submitted by three independent interdisciplinary teams of...

We present gene prioritization system (GPSy), a cross-species gene prioritization system that facilitates the arduous but critical task of prioritizing genes for follow-up functional analyses. GPSy's modular design with regard to species, data sets and scoring strategies enables users to formulate queries in a highly flexible manner. Currently, the system encompasses 20 topics related to conser...

When designing a plant for continuous or semi-continuous processes, such as paper pulp or petrochemical production systems, engineers face very complex tasks, which are only in part supported by software tools. The paper analyses the problem, proposes the RCAD software architecture and describes partial implementation results. The architecture, which is based on a simple yet powerful conceptual...

We consider the problem of securely computing the Greater Than (GT) predicate and its generalization – securely determining membership in a union of intervals. We approach these problems from the point of view of Q-Conditional Oblivious Transfer (Q-COT), introduced by Di Crescenzo, Ostrovsky and Rajagopalan [4]. Q-COT is an oblivious transfer that occurs iff predicate Q evaluates to true on the...

Crowdfunding represents a disruptive innovation in the banking industry by enabling the exploitation of market segments. Incumbents struggle to utilize this new phenomenon as crowdfunding is based on modules that have not been considered relevant for banking so far. Nevertheless, crowdfunding services are not entirely new compared to traditional banking. We argue that the modular design enables...

This paper introduces a component model that allows the modular design and development of components and applications for Open and Distributed Systems. It defines the concepts of components and reusable controllers, permits their modular composition to build up applications, and it is devised to address in an independent manner many of the specific issues of these systems, like heterogeneity, e...

In this work we present a critical assessment of some problems and open questions on the debated notion of modularity. Modularity is greatly in fashion nowadays, being often proposed as the new approach to complex artefact production that enables to combine fast innovation pace, enhanced product variety and reduced need for co-ordination. In line with recent critical assessments of the manageri...

Software systems made of software components are becoming more and more common. This paper surveys theories and techniques for designing and analyzing security of such systems. The paper gives an overview of security models, introduces formal foundations for system composition and security engineering, and investigates available techniques for security design and analysis, focusing on each tech...

This paper proposes a module of a high gain and high swing 2-stage amplifier. It is suitable for building a general operational amplifier in a modular fashion with various optional performances. The proposed module alone offers opened-loop voltage gain up to 124 dB and GBW of 10 MHz without loading conditions. To assemble a 124 dB voltage gain operational amplifier with load driving capacity of...
