Test analysis & fault simulation of microfluidic systems
This work presents a design, simulation and test methodology for microfluidic systems, with particular focus on simulation for test. A Microfluidic Fault Simulator (MFS) has been created based around COMSOL which allows a fault-free system model to undergo fault injection and provide test measurements. A post MFS test analysis procedure is also described.A range of fault-free system simulations have been cross-validated to experimental work to gauge the accuracy of the fundamental simulation approach prior to further investigation and development of the simulation and test procedure.A generic mechanism, termed a fault block, has been developed to provide fault injection and a method of describing a low abstraction behavioural fault model within the system. This technique has allowed the creation of a fault library containing a range of different microfluidic fault conditions. Each of the fault models has been cross-validated to experimental conditions or published results to determine their accuracy.Two test methods, namely, impedance spectroscopy and Levich electro-chemical sensors have been investigated as general methods of microfluidic test, each of which has been shown to be sensitive to a multitude of fault. Each method has successfully been implemented within the simulation environment and each cross-validated by first-hand experimentation or published work.A test analysis procedure based around the Neyman-Pearson criterion has been developed to allow a probabilistic metric for each test applied for a given fault condition, providing a quantitive assessment of each test. These metrics are used to analyse the sensitivity of each test method, useful when determining which tests to employ in the final system. Furthermore, these probabilistic metrics may be combined to provide a fault coverage metric for the complete system.The complete MFS method has been applied to two system cases studies; a hydrodynamic “Y” channel and a flow cytometry system for prognosing head and neck cancer.Decision trees are trained based on the test measurement data and fault conditions as a means of classifying the systems fault condition state. The classification rules created by the decision trees may be displayed graphically or as a set of rules which can be loaded into test instrumentation. During the course of this research a high voltage power supply instrument has been developed to aid electro-osmotic experimentation and an impedance spectrometer to provide embedded test

Seventh Annual Workshop on Space Operations Applications and Research (SOAR 1993), volume 1
This document contains papers presented at the Space Operations, Applications and Research Symposium (SOAR) Symposium hosted by NASA/Johnson Space Center (JSC) on August 3-5, 1993, and held at JSC Gilruth Recreation Center. SOAR included NASA and USAF programmatic overview, plenary session, panel discussions, panel sessions, and exhibits. It invited technical papers in support of U.S. Army, U.S. Navy, Department of Energy, NASA, and USAF programs in the following areas: robotics and telepresence, automation and intelligent systems, human factors, life support, and space maintenance and servicing. SOAR was concerned with Government-sponsored research and development relevant to aerospace operations. More than 100 technical papers, 17 exhibits, a plenary session, several panel discussions, and several keynote speeches were included in SOAR '93
Nonlinear Dynamics
This volume covers a diverse collection of topics dealing with some of the fundamental concepts and applications embodied in the study of nonlinear dynamics. Each of the 15 chapters contained in this compendium generally fit into one of five topical areas: physics applications, nonlinear oscillators, electrical and mechanical systems, biological and behavioral applications or random processes. The authors of these chapters have contributed a stimulating cross section of new results, which provide a fertile spectrum of ideas that will inspire both seasoned researches and students

Book of Abstracts of MICROBIOTEC09
Sítio da conferência: http://www.deb.uminho.pt/microbiotec09/This book contains the abstracts presented at the 3rd joint meeting of the Portuguese Society of
Microbiology and The Portuguese Society of Biotechnology - MicroBiotec09, held in Vilamoura, Portugal,
over 3 days, from the 28th to the 30th of November, 2009. MicroBiotec09 comes in the sequence of
previous conferences organized by each society, since 1982, date of the I Encontro Nacional de
Biotecnologia (Lisbon), till 2005, date of the first joint meeting - MICRO'05 + BIOTEC'05 (Póvoa de
Varzim). Following this joint meeting, another - MICRO 07 + BIOTEC 07 + XXIII JPG took place in Lisbon
(2007).
MicroBiotec09 is a joint organization of “Sociedade Portuguesa de Biotecnologia”, “Sociedade Portuguesa
de Microbiologia”, Institute for Biotechnology and Bioengineering (Universidade do Minho –
Departamento de Engenharia Biológica) and Centro de Recursos Microbiológicos (Universidade Nova de
Lisboa, Faculdade de Ciências e Tecnologia – Departamento de Ciências da Vida).
MicroBiotec09 brings together both young and established researchers and end users to discuss recent
developments in different areas of Biotechnology and Microbiology. The conference program has thus
been divided in 8 major sessions: Microbial Physiology, Molecular Biology and Functional Genomics; Cell
and Tissue Engineering, Biomaterials and Nanobiotechnologies; Clinical Microbiology and Epidemiology;
Environmental Microbiology and Biotechnology; Health and Pharmaceutical Biotechnology; Cellular
Microbiology and Pathogenesis; Industrial and Food Microbiology and Biotechnology; Bioinformatics,
Comparative Genomics and Evolution.
A special session to celebrate the 200th anniversary of Charles Darwin's birth and the 150th anniversary of
the publication of his landmark work “On the Origin of Species by Means of Natural Selection” will also
take place.
A total of 295 abstracts are included in the book, consisting of 6 invited lecturers, 10 oral presentations
and 44 short oral presentations given in 3 parallel sessions, along with 4 slots for viewing poster
presentations. All abstracts have been reviewed and we are grateful to the members of scientific and
organizing committees for their evaluations. It was an intensive task since 328 submitted abstracts were
received.
It has been an honor for us to contribute to setting up MicroBiotec09 during an intensive period of 6
months. We wish to thank the authors who have contributed to yield a high scientific standard to the
program. We are thankful to the sponsors who have contributed decisively to this event. We also extend
our gratefulness to all those who, through their dedicated efforts, have assisted us in this task.
On behalf of the Scientific and Organizing Committees we wish you that together with an interesting reading, the scientific program and the social moments organized will be memorable for all.Fundação para a Ciência e a Tecnologia (FCT
