Bloom filters are frequently used to perform set queries that test the existence of some items. However, Bloom filters face a dilemma: the transmission bandwidth and the accuracy cannot be optimized simultaneously. This dilemma is particularly severe for transmitting Bloom filters to remote nodes when the network band…
It is important for modern scanning microwave microscopes (SMMs) to overcome the effect of the surface roughness. Here, we report microwave conductivity imaging of the phase-separated iron chalcogenide KxFeySe2 (x = 0.8, y = 1.6–2), in which electric conductivity-induced contrast is distinguished from topography-induc…
A shutterless algorithm is implemented into the Xenics LWIR thermal cameras and modules. Based on a calibration set and a global temperature coefficient the optimal non-uniformity correction is calculated onboard of the camera. The limited resources in the camera require a compact algorithm, hence the efficiency of th…
Zhejiang Dali Technology Co. Ltd. is one of the major players in the China Infrared industry. The company has been working on infrared imagers using uncooled FPAs for about 15 years. It started the research and development of uncooled microbolometer detectors since 2006, and has brought several uncooled detectors into…
Natural dyes were extracted from the plant species Etlingera elatior, Duranta erecta and Amaranthus spp. that were collected from Keningau and Tambunan, Sabah, Malaysia. The possibility of photon-electron conversion was then assessed based on their absorption ability in the region of wavelength between 400-900nm. In a…
The methanation reaction is a promising method for the purification of natural gas, in which the acid gases of CO2, is eliminated by catalytic conversion. The advantage of catalytic technology is the utilization of CO2 present in the production of methane gas. The used of alumina supported cerium oxide as the based ca…
In this article, we report three nanofillers filled polymer composite systems. Nanofillers composed of alumina, titania and organoclay were embedded separately in 50% polypropylene (PP) and 50% ethylene propylene diene monomer (EPDM) blends. The nanocomposites were prepared using an internal mixer and were molded usin…
Abstract. Waste tires, which are an abundant waste product of the automobile industry, were used to prepare activated carbon by means of physical and chemical activation. A two-stage process was used, with a semi-carbonization stage as the first stage, followed by an activation stage as the second stage.All experiment…
The reliability assessment of heritage structures is becoming an increasingly important and frequent engineering task. Probabilistic methods and Bayesian updating techniques are often combined to obtain realistic estimates, also aiming to target the best the possible interventions. Moreover, several factors often cont…
There have been numerous research efforts directed towards the synthesis of gold (Au) nanoparticles (NPs) and the understanding of their formation, so that their size, shape, and stability can be well controlled for desired applications. Here, we report a dry photo-reduced method of Au NP formation directly on a membr…
A hollow R.R. Moore rotation fatigue sample made of AISI 9310 is processed using vacuum carburization and high pressure gas quenching. The vacuum carburization schedule is designed to through carburize the thin wall section of the fatigue sample to 0.7% wt.% carbon, followed by 10 bar nitrogen quench. Some samples sho…
In this work, we show a general approach for inhomogeneous composite thermoelectric systems, and as an illustrative case, we consider a dual thermoelectric cooler. This composite cooler consists of two thermoelectric modules (TEMs) connected thermally in parallel and electrically in series. Each TEM has different ther…
We report the magnetotransport properties and the microstructure of polycrystalline current-perpendicular-to-plane giant magnetoresistance (CPP-GMR) pseudospin valves (PSVs) using (001) textured Co2Fe(Ga0.5Ge0.5) (CFGG) ferromagnetic layers grown on a conductive (Mg0.5Ti0.5)O (MTO) buffer layer. The PSV with a 10 nm C…
Using Monte Carlo simulation, we have studied the magnetic and thermal properties of a four sublattice ferromagnetic (FM) and anti-FM (AFM) double-layer superlattices system in a longitudinal magnetic field. The effects of the intralayer AFM exchange coupling J2, the single-ion anisotropy D and the longitudinal magnet…

H2 permselective silica hybrid membranes were successfully prepared by using a counter diffusion chemical vapor deposition (CVD) method. Hexyltrimethoxysilane (HTMOS), phenyltrimethoxysilane (PhTMOS) or diphenyldimethoxysilane (DPhDMOS) were used as silica precursors. The oxidants were O3 or O2. These reactants were p…
Double-gate Sb-SnO2 nanowire electric-double-layer (EDL) transistors with in-plane gates were fabricated using only one shadow mask. The threshold voltage of such devices can be tuned in a wide range from −0.13 V to 0.72 V by the in-plane gate, which allows the device to switch from depletion-mode to enhancement-mode…
Carbon nanotubes are commonly used to create polymer-nanotube composite for various applications. To suffice the needs of the emerging interest in utilizing nanotube, a great concern in creating a stable dispersion of the nanotube in solvent emerged. There is a paramount need to enhance the adhesion between the polyme…
