Abstract The television broadcasting industry is of crucial economic and social importance. Traditionally, this has been dominated by free-to-air TV (FTV) but due to technological progress, subscription-based pay (PTV) emerged as a competing business model. A key question for the PTV broadcasters whether air commercials in addition charging subscription fees. Based on theoretical model asymmetr...

This paper reports an enhancement in fluorescence detection via the formation of fluidic microlens in micro-optical fluidic system (MOFS). The fluidic microlens is formed by three laminar flows in the expansion chamber. By changing the flow rate of each flow, the shape and focal length of the fluidic lens will be changed. Therefore, the fluidic microlens provides a wide range of tunability to e...

The formation, evolution, and interactions of a closely spaced pair of coflowing rectangular synthetic jets are investigated using particle image velocimetry. The dynamics of the combined jet is determined by the interactions of the counter-rotating vortex pairs that form each jet. These vortex pairs are formed along the long edges of the orifice of each jet by the time-periodic motion of a dia...

The COordinate Rotation DIgital Computer CORDIC algorithm has proved its versatility in computing various transcendental functions by only using the shift and adds operations. This paper presents a new hardware efficient scaling free CORDIC algorithm to operate in vectoring and in rotation mode. The micro rotation of the vector is always in one direction with no scale factor correction. The Ran...

Abstract REGULUS is an Iodine-based electric propulsion system. It has been designed and manufactured at the Italian company Technology for Propulsion Innovation SpA (T4i). integrates Magnetically Enhanced Plasma Thruster (MEPT) its subsystems, namely electronics, fluidic, thermo-structural in a volume of 1.5 U. The mass envelope 2.5 kg, including propellant. targets CubeSat platforms larger th...

The coccinellid Harmonia axyridis is a recent arrival in the UK and is an intraguild predator of the entomopathogenic fungus Pandora neoaphidis. Harmonia axyridis entirely consumes P. neoaphidis-sporulating cadavers and this may have a negative effect on the epizootic potential of P. neoaphidis. Here we assessed within plant transmission, and between plant vectoring, of P. neoaphidis in the pre...

The Laser Direct Synthesis and Patterning (LDSP) technology has advantages in terms of processing time and cost compared to nanomaterials-based laser additive microfabrication processes. In LDSP, a scanning laser on the substrate surface induces chemical reactions in the reactive liquid solution and selectively deposits target material in a preselected pattern on the substrate. In this study, w...

Electric vehicles with multiple motors allow torque-vectoring, which generates a yaw moment by assigning different motor torques at the left and right wheels. This permits designing the steady-state cornering response according to several vehicle handling quality targets. For example, as widely discussed in the literature, to make the vehicle more sports-oriented, it is possible to reduce the u...

Engineering education in fluidics means to convey the physical principles behind pneumatic or hydraulic building blocks such as valves or cylinders. Up to now fluidic hardware plays an important role in this connection: Education laboratories with semi-professional components are used to build up small circuits and to perform experiments respecting hydraulic and pneumatic laws of nature. Based ...
