Smart structures are highly interconnected adaptive systems that are coordinated by cyber systems to optimize specific system objectives. To capture realistic IoT scenarios we must employ threat models that allow untrusted behavior and address system vulnerabilities, exploits and attack vectors. Resilience is defined in terms of stability, resistance to damage and self-healing. In this paper we...

This paper introduces integral resonant control, IRC, a simple, robust and well-performing technique for vibration control in smart structures with collocated sensors and actuators. By adding a direct feed-through to a collocated system, the transfer function can be modified from containing resonant poles followed by interlaced zeros, to zeros followed by interlaced poles. It is shown that this...

The vector wavelet multi-resolution technique based on the orthogonal wavelet transform was used to analyze the velocity vector data that were simultaneously obtained by sixteen X-wires in the turbulent near-wake of a circular cylinder at different streamwise positions. The instantaneous velocity vector field is decomposed into the multi-scale structures, and its sectional streamline of various...

All forms of e-government are integrated in an organizational structure defined by the institutional arrangements of the specific state. Thus when using e-government applications to make the government smarter it has to be contextualized in the specific structure of government. A common institutional arrangement is to divide governments into different levels – a multi-level government system. T...

Smart materials based on carbon-fibre-reinforced plastic (CFRP) with embedded PZT sensors and actuators are expected to be a favourite composite for vibration damping and noise reduction. Due to the wide variety of physical properties of the components, various damage mechanisms may reduce or even remove the sensing and actuating capabilities of the piezoceramic material. Comprehensive non-dest...

We study transient ®nite deformations of a neoHookean beam or plate with piezoelectric (PZT) patches bonded to its upper and lower surfaces. The constitutive relations for the PZTs are taken to be linear in the Green-Lagrange strain tensor but quadratic in the driving voltage. A ®nite element code using 8-noded brick elements has been developed and validated by comparing computed results with e...

Computational micromagnetics in three dimensions is of increasing interest with the development of magnetostrictive sensors and actuators. In solving the Landau-Lifshitz-Gilbert (LLG) equation, the governing equation of magnetic dynamics for ferromagnetic materials, we need to evaluate the effective field. The effective field consists of several terms, among which the demagaetizimg field is of ...
