We used aluminum (Al) layer as the metal cathode and several pairs of SiO2/TiO2 QWL as the DBR.
The typical deposition rates of organic material, LiF and Al were 0.6, 0.1 and 5.0 Å/s, respectively.
The configuration of the MOLED is glass/dielectric mirror/ITO/HTL (x nm)/EML (y nm)/ETL (z nm)/LiF (0.3 nm)/Al (300 nm).
EL emission spectra measured at different angles for Device B.

El-Sebaii et al.[7] designed a transient mathematical model of a single pass flat plate solar air heater.
El-Agouz[10, 11] and Mehrgoo et al.[12] also found that improving the temperature of feed water increased the productivity.

Introduction Since the first report by Burroughes et al. in 1990 [1], flexible and tunable polymeric light-emitting diodes (PLED) based on conjugated polymers have been extensively investigated [2].
Tang et al. synthesized copolymers comprised of 9,9-dihexylfluorene and thieno [3,2-b] thiophene moieties using the Suzuki coupling reaction.
Their EL properties were summarized in table 1.
Figure 2 (right) shows the EL spectra of PLED based on the two polymers at a voltage of 6V.

An experimental set up was devised by Zeinoddini et al[2]. to provide benchmark data on the response of axially loaded steel tubes subjected to lateral dynamic impact loads.
The work performed by Zeinoddini et al. has not been extended into typical steel columns found in onshore structures.
The models were thoroughly validated using experimental data reported by Zeinoddiniet al[2]. on steel tubular members that were laterally impacted while subjected to a sustained axial load.

ACI440.2R-02 [1], El-Mihilmy and Tedesco[2], Charkas et al[3], Faruqi et al[4], and Said[5] proposed different formulae to evaluate the deflection of FRP-strengthened RC beams.
’s, ACI440’s and Charkas et al’s methods at rebar yielding and ultimate state ,respectively; *ratios of calculated-to-experimental deflections.
Present Model El-Mihilmy’s equation is much more applicable for engineering design than other methods.
Therefore, by analyzing the relationship between the deflections calculated by El-Mihilmy’s equation and the experimental ones, this paper investigates the behavior of deflection affected by the preload level and the reinforcement ratio, and develops the modified equations based on El-Mihilmy’s equation to evaluate the deflection of CFRP-strengthened beams.
