To reveal the scale-dependences of the transport of turbulent energy in a channel flow, the constituents of the budget equation of turbulent energy for the Fourier modes of velocity fluctuations are computed by using direct numerical simulations. At each height in the buffer and overlap regions, the transport in the wall-normal direction by the...

In the presence of magnetic helicity, inverse transfer from small to large scales is well known in magnetohydrodynamic (MHD) turbulence and has applications in astrophysics, cosmology, and fusion plasmas. Using high resolution direct numerical simulations of magnetically dominated self-similarly decaying MHD turbulence, we report a similar...

Twirre is a new architecture for mini-UAV platforms designed for autonomous flight in both GPS-enabled and GPS-deprived applications. The architecture consists of low-cost hardware and software components. High-level control software enables autonomous operation. Exchanging or upgrading hardware components is straightforward and the architecture...

Tugite and Shiguchi are traditional architectural techniques of Japan, which connect materials without the use of nails or adhesives. Tugite is a technique to connect materials to augment the lack of length of available materials. Shiguchi is a technique to connect materials at an angle. With a firm basis in this tradition and the craftsmanship...

The paper concerns the potential of sensors as architectural design tools in different spatial and temporal scales. In particular, the focus is on how sensors are able to operate in a constantly changing environment, and how sensors might nurture an intuition of otherwise non perceivable aspects of performance within architecture.The study...

A novel approach is presented to predict wind pressure on tall buildings for early-stage generative design exploration and optimisation. The method provides instantaneous surface pressure data, reducing performance feedback time whilst maintaining accuracy. This is achieved through the use of a machine learning algorithm trained on procedurally...

The effects of altering the lower thermal boundary condition of a methanol pool from -5 °C to 50°C was investigated within a 90 mm diameter and 12 mm deep quartz burner under steady state burning condition in a quiescent air environment. The temperature and velocity within the liquid were measured by a single thermocouple traversed through the...

Fiber reinforced cementitious composite (FRCC) has a great capability for selfhealing of cracks. Concrete cracks with a sufficiently small crack width (below 0.1 mm) can be closed and self-healed by crystallization of calcium carbonate in the presence of moisture, even in the case of ordinary concrete. Such precipitation is caused by reaction of...

Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene...

Supramolecular self assembling hydrogen bonded polymeric materials are of great importance due to its practical relevance. Well designed molecules based on these concepts can produce polymeric materials with “responsive” properties like self healing even in coating application. The reversible, non-covalent hydrogen bonding interactions are a...

The use of dynamic bonds in self-healing polymeric systems allows restoring of the chemical structure and mechanical properties multiple times. In this respect, the use of ionomers represents a promising approach. The strong interaction between ionic moieties within a non-polar matrix leads to microphase separation and a behavior similar to...

Argentine culture has significant connections to Italian culture because the two countries have a long history of migration. Today, thanks to ICT, Social Media and Mobile Technologies, italo-argentinians can have a continuos interaction that let them construct and re-construct, day by day, their hybrid identity. Glocalization has permit to...

Variational data assimilation, also sometimes simply called the ‘adjoint method’, is used very often for large scale model calibration problems. Using the available data, the uncertain parameters in the model are identified by minimizing a certain cost function that measures the difference between the model results and the data. A variational...
