in this paper, zno thin film is deposited on slide glass substrate using the sol-gel process. presenting well-defined orientation of zno thin films nanostructure were obtained by dip coating of zinc acetate dihydrate, monoethanolamine (mea), de-ionized water and isopropanol alcohol. the annealed zno thin films were transparent ca 85-90% in visible range with an absorption edges at about 375 nm....

Optically transparent wood, combining optical and mechanical performance, is an emerging new material for light-transmitting structures in buildings with the aim of reducing energy consumption. One of the main obstacles for transparent wood fabrication is delignification, where around 30 wt % of wood tissue is removed to reduce light absorption and refractive index mismatch. This step is time c...

Partial Order Reduction (POR) techniques improve the basic model checking algorithm by reducing the numbers of states and transitions explored in verifying a property of the model. In the “ample set” POR framework for the verification of an LTL−X formula φ, one associates to each state s a subset Ts of the set of all transitions enabled at s. The approach requires that whenever Ts is a proper s...

Under pressure, metals exhibit increasingly shorter interatomic distances. Intuitively, this response is expected to be accompanied by an increase in the widths of the valence and conduction bands and hence a more pronounced free-electron-like behaviour. But at the densities that can now be achieved experimentally, compression can be so substantial that core electrons overlap. This effect drama...

Users increasingly store data collections such as digital photographs on multiple personal devices, each of which typically presents the user with a storage management interface isolated from the contents of all other devices. The result is that collections easily become disorganized and drift out of sync. This thesis presents Eyo, a novel personal storage system that provides device transparen...

What would be today's programming language of choice for distributed computing in the Internet? Few would doubt that it should be Java [Arnold/Gosling 96], given its platform independence and the possibility of loading Java applets over the network. So if the prophets and the faithful are right, the basic design and the special features of Java should make distributed programming easy for the e...

It is proposed that the concept of transparent telepresence can be closely approached through high fidelity technological mediation. It is argued that the matching of the system capabilities to those of the human user will yield a strong sense of immersion and presence at a remote site. Some applications of such a system are noted. The concept is explained and critical system elements are descr...

Plasmonic graphene is fabricated using thermally assisted self-assembly of silver nanoparticles on graphene. The localized surface-plasmonic effect is demonstrated with the resonance frequency shifting from 446 to 495 nm when the lateral dimension of the Ag nanoparticles increases from about 50 to 150 nm. Finite-difference time-domain simulations are employed to confirm the experimentally obser...

Dynamic optimization refers to the runtime optimization of a native program binary. This paper describes the design and implementation of Dynamo, a prototype dynamic optimizer that is capable of optimizing a native program binary at runtime. Dynamo is a realistic implementation, not a simulation, that is written entirely in user-level software, and runs on a PA-RISC machine under the HPUX opera...

This paper studies the problem of learning data automata (DA), a recently introduced model for defining languages of data words which are finite sequences of pairs of letters from a finite and, respectively, infinite alphabet. The model of DA is closely related to general Petri nets, for which no active learning algorithms have been introduced so far. This paper defines transparent data automat...
