In a crisp commitment schemes, a commitment must be opened using a unique opening key. However in such schemes, there could be many instances where the transmission medium or channel is corrupted by some kind of communication (transmission) noise. In this paper, we proposed a new scheme that enables the injection of fuzziness property to current ordinary crisp commitment scheme. In this way, the uncertainty occurring due to the noise presence is mitigated. It is a known fact that this kind of uncertainty naturally leads to the introduction of a fuzziness dimension to the commitment problem at hand. The security characteristic of our scheme relies on any cryptographic assumption unlike the fuzzy commitment scheme in the literature, which is based on hash function and should be strongly collision-free for the scheme to be secure.

In the present paper, we present the design of a filter formed by two waveguide couplers and one microcavity in a photonic crystal (PC) with a square lattice consists of long cylinders of silicon (Si) rods. Waveguide 1 and waveguide 2 are obtained by removing one row of rods. They are used to couple light in and out the microcavity. The finite difference time domain (FDTD) method (fullwave simulator) has been used to simulate optical propagation in this filter. Two rods have been located in the input and output channel waveguides. Their numbers and size have been varied in order to optimize the transmitted power and quality factor of the microcavity. We demonstrate that the calculated Q factor for the designed cavity increases with displacing rods, while the calculated modal volume remains almost constant.

The current study relates to the response of mTHPC to exposure using femtosecond duration laser pulses. Experiments using a Ti: sapphire laser delivering ∼130 fs pulses at a wavelength of ∼ 800 nm show that fluorescence can be excited in this photosensitiser, even though the photon energy is less than the energy of the fluorescing state. The fluorescence amplitude is found to exhibit an irradiance dependence of the form In where n ≈ 2, which is consistent with two-photon excitation. Also the effect of photobleaching was studied using one and two photon excitation.

We propose a fault management and protection system for the ring-and-spur long reach PON. We exploit an adapted, enhanced performance, and inexpensive passive optical components in the field and electronic switches in the central office (CO). Our system allows detecting and localizing not only faulty segments but also faulty nodes, hence alleviating the false alarm probability encountered in previous systems. We show that using ring duplication protection in LR-PON can save half the cost compared to full duplication protection with relatively high reliability (99.9925). We derive an expression for the upper bound notification and recovery times. Moreover, we found that our system can recover from a fault in about 0.5ms as an upper bound.

A pipelined ADC equation-based design space exploration methodology targeting minimum power dissipation is presented. While distinct frontiers are drawn between system-level and circuit-level design phases, this paper shows the importance of a refinement step between both phases. At the system-level, all possible architectures are examined followed by behavioral validation. Using a circuit sizing tool, different circuit topologies are investigated. The refinement phase proves to be important to increase the accuracy of system-level calculations by remapping new circuit-related parameters using the achieved circuit performances. The flow was built in an open system environment where the user has the freedom to change the modeling approach at any level, introduce different equations, and relax/tighten design constraints. An 11-bit ADC design test case is given to illustrate the methodology.

Metamaterials have been shown to enhance specific performance parameters of low profile and high-profile antennas. Our focus in this paper on specifically increasing the gain of low-profile antennas and in particular the microstrip patch antenna. By placing a metamaterial slab above a microstrip patch antenna (as a superstrate), we show that the gain of the antenna can be enhanced appreciably. The key advantage of using the superstrate is to maintain the low-profile advantage of microstrip patch antennas. In previous works, different types of superstrates were proposed to enhance the gain of microstrip antennas, however, to the best of our knowledge, no theory was developed to understand the mechanism behind the enhancement in the gain. In this paper, we present a simple analytical formulation that provides a very accurate prediction of the gain when a superstrate is used. In fact, our analytical technique is capable of predicting the gain when a multilayer superstrate structures is used. To validate the theory of gain enhancement, antennas and superstrates using metamaterials were fabricated and tested in an echoic chamber. The metamaterials developed were based on split-ring resonators. Strong agreement was found between the measurements and full-wave simulation using commercial tools. Finally, we present optimization results to demonstrate the maximum gain enhancement potential that can be achieved when superstrates are used.

CdS quantum dots (QDs) capped with mercaptosuccinic acid (MSA) as the surface passivating ligand were anchored to electrospun TiO2 nanorod surfaces using the terminal carboxylic acid groups present on MSA. The as-synthesized materials and the dye-sensitized solar cells were characterized by spectroscopy, microscopy and photocurrent measurements, respectively. Best solar cells fabricated by the method showed an efficiency of 0.07%. We believe that the simple, one-pot fabrication of the QDs and their assembly into solar cells are significant steps in QD-sensitized solar cell research.

Zinc oxide (ZnO) photoanodes of two different morphologies — nanorods and nanosheets are used to fabricate dye sensitised solar cells in order to study the influence of morphology on device performance. Characteristics such as dye loading capacity and light scattering ability of the photoanodes depend on the morphology to a large extent. This leads to change in the electron transport properties, which in turn affects power conversion efficiency. Here we report the difference in the charge transport properties of these morphologies evaluated using the time resolved photocurrent measurements. The photocurrent transients for ZnO nano-rod film exhibited dual peak behaviour, whereas transients for ZnO nano-sheet film exhibited only one peak as the time delayed second peak corresponding to slow electron diffusion was totally suppressed. The transient photocurrent decay also indicates that the charge transport rate is much faster in the ZnO nano-sheets, which allows the efficient charge collection over much larger thickness compared to other ZnO nano-rod film. The power conversion efficiency (PCE) of the devices was found to be 1.6% and 1.5 % for the ZnO-nano-rod and nano-sheet based dye sensitized solar cells respectively. A comparative study is performed and the photovoltaic parameters obtained in each case are correlated with the photocurrent transients enabling better understanding of the impact of morphology.

This paper describes the design and working principles of an experimental multimode radar with a stepped-frequency Synthetic Range Profiling (SRP) and Inverse Synthetic Aperture Radar (ISAR) capability for the purpose of operator-based classification of small to medium sized sea vessels in littoral condition. The experimental multimode radar is based on an experimental tracking radar that was modified to generate SRP and ISAR images in both search and tracking modes. The architecture and functionality of the experimental system is described. Initial results from field experiments are presented to demonstrate the functionality of the system.
