Les progrès constants de la technologie de dépôt de couches minces au cours des dernières décennies ont permis la production de filtres optiques multibandes haute performance, répondant ainsi à la demande croissante d'instruments de fluorescence multispectraux. Bien qu'il existe maintenant une large gamme de filtres standards conçus pour une grande variété de fluorophores, la sélection de filtres appropriés est souvent un processus complexe. Nous présentons ici les caractéristiques techniques à considérer pour la conception d'un tel système multiplexe.

ABSTRACTBackgroundEndoscopic variceal band ligation (EVL) is the preferred method of treating variceal hemorrhage in adults. The need to reinsert the endoscope after reloading for each varix ligation has been a drawback. The Saeed multiband ligator allows ligation of multiple varices during a single insertion. The multibander has not been used previously in children.MethodsTwenty‐eight consecutive children were referred to a pediatric liver unit because of esophageal variceal bleeding from 1998 to 2000.

Abstract Northeast U.S. winter storms commonly exhibit multiple meso-β-scale (L &lt; 200 km) bands of enhanced radar reflectivity and precipitation.

Banding can occur in several configurations among storms, and banding characteristics can differ at different times within the same storm. We classified 6-h storm periods as contai

Wireless devices such as smart meters, trackers, and sensors need connections at multiple frequency bands with low power consumption, thus requiring multiband and efficient antenna systems. At the same time, antennas should be small to easily fit in the scarce space existing in wireless devices.

In this paper we concentrate on design of multiband antenna for existing wireless services. At present, the available techniques are modifying the main radiator (bending, folding, meandering and wrapping) which affects the size of antenna. This makes it more complex in implementing on RF circuits. To achieve multiband capability along with compactness in size we go with slotted multiband planar system. Here we design antenna in such a way in works on quad band frequency i.e., GPS, WiMax and WLAN(IEEE 802.11 a,b) for indoor application.

The compactness of the two demonstrated components is well kept by putting all stubs with resonators inside the components themselves.

In modern world, communication devices need to be operated for more than one frequency bands. Lot of research works were carried out in the field of multiband antennas. The one major concern in the design of multiband patch antenna are the gain and bandwidth. Both gain and bandwidth of the multi band antenna can be improved for the better performance. In this paper a triangular multiband antenna is designed and the gain of the antenna is enhanced by the blend of reactive impedance surface and Frequency selective surface. The proposed antenna resonates 3.4 GHz, 4.2 GHz, 6.75 GHz,7.1 GHz, 7.5 GH

Abstract:

Here an electrically small multiband antenna based on spoof localized surface plasmons (LSPs) has been proposed using corrugated ring resonator printed on a thin dielectric substrate with complementary metallic spiral structure (MSS) on the ground plane. It has been found that the resonant frequencies of spoof LSPs redshift by tuning the arm length of the complementary MSS, which leads to the miniaturization of the antenna. The fabricated multiband antenna has a small size of only 0.11λ × 0.1λ, covering GSM900, GSM1800, and WiFi bands. Such electrically small multiband antenna with high gain i

Abstract:

A multiband and wideband frequency reconfigurable antenna is presented. A wideband from 3.5 GHz to 9.0 GHz is achieved by introducing one stripline in the middle of a slotted bowtie antenna, whereas multiband is obtained by integrating an additional two slotted arms at the end of bowtie-shaped. As a result, the antenna operated at multiband mode (1.7 GHz and 2.6 GHz) and wideband mode (3.5 GHz to 9.0 GHz) simultaneously. The reconfigurability of the antenna is attained through switches. Five states are achieved with three pairs of switches configurations. All results are presented and discusse

Abstract:

Deep learning methods have been successfully applied for multispectral and hyperspectral images classification due to their ability to extract hierarchical abstract features. However, the performance of these methods relies heavily on large-scale training samples. In this paper, we propose a three-dimensional spatial-adaptive Siamese residual network (3D-SaSiResNet) that requires fewer samples and still enhances the performance. The proposed method consists of two main steps: construction of 3D spatial-adaptive patches and Siamese residual network for multiband images classification. In the fi

Abstract In this paper, an effective medium ratio obeying, negative refractive index, compact meta-atom was designed, manufactured and tested for operation in a multiband microwave regime. The proposed meta-atom structure obeyed better effective medium ratio. The results of the measurement were verified by the commercially available Computer Simulation Technology (CST) Studio Suite 2014 simulator. The effective medium ratio obeying meta-atom displayed multiband response, in conjunction with negative refractive index property over a certain frequency band in the microwave frequency span.

Abstract:

The paper considers the problem of optimizing gas-discharge sources of multiband UV radiation – excilamps. A method is proposed for estimating the ratio of partial pressures of the components of a gas mixture, which makes it possible to simplify the process of developing a multiband excilamp with the desired power ratio of the emission bands. It is shown that the optimization of a multiband excilamp on a mixture of one noble gas with several halogen carriers can be reduced to the problem of optimizing an excilamp on a two-component mixture.

Abstract This paper investigates the ability of the Weather Research and Forecasting (WRF) Model in simulating multiple small-scale precipitation bands (multibands) within the extratropical cyclone comma head using four winter storm cases from 2014 to 2017. Using the model output, some physical processes are explored to investigate band prediction. A 40-member WRF ensemble was constructed down to 2-km grid spacing over the Northeast United States using different physics, stochastic physics perturbations, different initial/boundary conditions from the first five perturbed members of the Global
