This paper presents a novel technique for long survival observation of Caenorhabditis elegans (C. elegans) inside Environmental-SEM (E-SEM) for nanomanipulations. We have developed the nanorobotic manipulation system inside an Environmental-Scanning Electron Microscope (E-SEM) integrated optical microscope (OM) for nanobiomanipulation platform. Our platform provides a real-time high resolution image under water-contained condition in nano-meter high-magnification image. One of the difficulties on the E-SEM observation is to maintain the biological sample on survival condition in long time. In this paper, we propose a coating method on the C. elegans or sample substrate for maintain the survival condition to keep in wet-condition. The proposed technique is useful to operate the nanomanipulation on C. elegans body, for example nano-injection of functional micro-nano beads as demonstrated in this paper.

This paper covers the authors’ recent research in the area of evolutionary design optimisation in electronic application domain (Evolvable Hardware). This will be also presented in the context of biologically inspired systems where Evolvable Hardware is concerned with evolutionary synthesis of self-healing systems and potentially hardware capable of online adaptation to dynamically changing environment. We will also illustrate how EAs can produce novel and unintuitive design solutions, and possibly new design principles. The novelty of this research project addresses this compelling change in the traditional landscape of the associated research disciplines by seeking to provide a novel biologically inspired mechanism to support the design optimisation of self-healing architectures, that is Evolvable-Embryonics.

Pneumatic systems are well known for their advantages, simplicity and can be applied in various industrial applications. This paper presents a comparative study of tuning methods on Proportional-Integral (PI) controller for position control performance both in simulation and in real system. A PI controller designed by optimization with the Particle Swarm Optimization (PSO) algorithm is proposed and its output is compared with the Ziegler-Nichols (Z-N) formula and manual (trial and error) results. Performance assessment of the tuned controllers was performed in MATLAB Simulink. It was observed that the controller designed using PSO gives better results and performance compared to the Z-N formula and manual tuning in simulation and real-time.

The paper explores the ability of numerical simulations for Lamb wave propagation in plates exposed to temperature fluctuations. The local interaction simulation approach is used for wave propagation modelling. The newly developed parallel computation technology - offered by modern Graphics Processing Units (GPUs) and Compute Unified Device Architecture (CUDA) used in low-cost graphical cards - is used in these numerical simulations. This allows for very efficient wave propagation simulation for various temperatures. Numerical simulation results can be used more effectively to develop new signal processing techniques to compensate for temperature effects.

Vibrothermography is a nondestructive testing method that monitors heat produced by damage under vibration and/or ultrasonic excitation in order to evaluate the structural health. The paper investigates practical aspects of vibrothermographic testing of structures. Measurements in two typical application areas of vibrothermography are presented and discussed. The examples are weld test specimens and a military aircraft fuselage skin. Measurements have been performed with use of an in-house vibrothermographic testing system. In case of welded specimens a series of carbon steel test samples with different flaw types have been investigated. In case of aircraft testing, field measurements have been performed on a wing and fuselage sections in order to assess the structural integrity. The paper discusses practical aspects related to field measurements with use of vibrothermography and presents thermal image processing techniques which allow to obtain the best flaw detection results. Applied image processing techniques allow increasing the quality and readability of the results coming from field measurements with low thermal response from the structure. The paper is concluded with a discussion on applications of vibrothermographic testing in Structural Health Monitoring applications.
