Inkjet printing has been used as an additive manufacturing method to fabricate organic light emitting diode (OLED). By changing the type and proportion of solvent inks adjusting parameters ink droplets, uniform ejection multi-nozzle is achieved volume deviation jet controlled at about 5% when poly(3,4-ethy lenedioxythiohene) : poly (styrenesulfonate) (PEDOT:PSS), hole injection layer materials,...

A unfied theory of four-dimensional gravity together with the standard model is presented, with supersymmetry breaking of M-theory at a TeV. Masses of the known particles are derived. The cosmological constant is quantum generated to the observed value. Quantum corrections to the classical compactification are analyzed, and the scenario is stable.

This paper examines the assumption that Australian English vowel variation within urban centres is restricted to broadness variation and is a consequence of socioeconomic rather than regional factors. The acoustic structure of vowel realisations for subjects across three different regions in Sydney is compared to shed some light on the theory of regional uniformity. 95 adolescent female speaker...

Previous research on the tone system of Yucatec Maya provides contradictory accounts which this paper intends to do away with, disentangling tonal and intonational effects. The first part presents the mere realisation of lexical high and low tones, the only tonal distinction we identify for Yucatec Maya. Second, we claim that in Yucatec Maya no interaction exists between intonation and lexical ...

In some technologicalframe-works, such as Charge Routing Networks (CRNs) ,or fiber-optic filters, only positive state-space realizations of digital signal processing algorithms, such as filters or control laws, can be implemented. On the other hand, the imposition of an a priori positivity constraint on the processing algorithm is a too strong design limitation. For this reason, some authors st...

In some technological frame-works, such as Charge Routing Networks (CRNs), or fiber-optic filters, only positive state–space realizations of digital signal processing algorithms, such as filters or control laws, can be implemented. On the other hand, the imposition of an a priori positivity constraint on the processing algorithm is a too strong design limitation. For this reason, some authors s...

This paper develops the first prototype hardware for TDD two-way multi-hop relay network with MIMO network coding. Since conventional wireless multi-hop relay networks have a drawback of low data rate, TDD two-way multi-hop relay networks have been studied as a solution to realize high data rate recently. In the networks, forward and backward streams are spatially multiplexed by using interfere...

The multi-robot coordination task is investigated in its Representation Space (RS). First, the RS model of the robot system as well as its prescribed task is formulated by clarifying the internal and external constraints affecting task realization. All constraints are depicted as unreachable areas in RS model. Then, whether a task is feasible or not is transformed to check 1) if the final repre...
