As the technology scales toward deeper submicron, system-on-chip designs have migrated from fairly simple single processor and memory designs to relatively complicated systems with higher communication requirements. Network-on-chip architectures emerged as promising solutions for future system-on-chip communication architecture designs. However, the switching and routing algorithm design of network-on-chip...
A novel angular independent dual-band FSS for multi-frequency communication is discussed in this letter. The proposed FSS with closely spaced response is consist of improved cross-shaped metal strips and a dielectric substrate. The unit cell size of the proposed FSS is 0.13λ×0.13λ where λ corresponds to the wavelength of the first resonant frequency. The proposed FSS exhibits dual stop band characteristics...
This paper presents a dual-band design of reflectarray antenna by using metallic elements for high energy efficiency at 28 and 60GHz bands. The dual-band operation is created by considering the frequency bands below and above the cutoff frequency of metallic waveguides. This frequency band separation differentiates the waveguide's characteristics as a resonant and non-resonant reflecting elements,...
In order to improve the gain of the array antenna element in the W-band and reduce its horizontal dimension, The directional radiation antenna loading dielectric sheet based on SIW technology is proposed. The antenna uses a conventional micro strip line to feed the gradient open micro strip line. Then the gradient open micros trip line feeds the SIW. Finally, the dielectric sheet loaded in SIW will...
Crocodiles possess dome shaped pressure receptors called integumentary sensory organs (ISOs) on their skin, which assist crocodiles in sensing flows and locating the origin of the disturbances created by movements of other animals. The surface of each ISO is equipped with mechanoreceptors and free nerve endings, which together carry out the task of receiving mechanical stimulus. Inspired by ISOs of...
For an electrochemical sensor to perform accurate and reliable measurement, having a reference electrode with consistent potential is required. This predetermined potential is the reference point to which either controlled or measured potential of the working electrode is compared. Generally, conventional silver/silver chloride (Ag/AgCl) reference electrodes with aqueous inner electrolyte are the...
This paper presents a circularly polarized reflectarray with linearly polarized feed operating at 28GHz for 5G applications. The proposed reflectarray is composed of a flat reflecting surface populated with numerous two-layer ground-backed non-resonant subwavelength rectangular patch elements which are in staggered arrangement and a Vivaldi antenna as the linearly feeder. Simulated results demonstrated...
Logistics distribution center location problem is a hot topic nowadays. We choose a medium-sized city group to study in this paper. The improved artificial immune algorithm based on similarity vector distance selection is used for the logistics distribution center location problem. The algorithm uses the threshold value to restrict concentration calculation of two antibodies from two aspects which...
Recently, the minimum mean squared error (MMSE) has been a benchmark of optimization criterion for deep neural network (DNN) based speech enhancement. In this study, a probabilistic learning framework to estimate the DNN parameters for single-channel speech enhancement is proposed. First, the statistical analysis shows that the prediction error vector at the DNN output well follows a unimodal density...
Shenyang was a representative heavily polluted industrial city in northeast China. Two types of urban area with significant spatial position difference were divided by arterial traffic as the surrounding and the core urban area. To reduce the impact of disturbing factors such as firecrackers in the traditional Chinese festivals, the observation period of the monitoring data was selected from November...
To enhance the accuracy and improve the efficiency of dictionary learning algorithm for compressive data gathering (CDG) in wireless sensor networks (WSNs), a robust efficient dictionary learning (REDL) algorithm is proposed. REDL algorithm separates outliers from training data by sparse coding them on identity matrix, and double-sparsity dictionary structure is introduced into the algorithm to provide...

The advanced system consists of 64 channels split into 4 column in azimuth and 16 rows in elevation. This airborne experiment system serves as a test bed for the development, implementation and testing of digital beamforming techniques for future High-Resolution Wide-Swath...
This paper studies the strategic version of single point weighted Steiner tree problem. We focus on Bayesian mechanism design setting for the problem. We find the optimal mechanism for it and prove that the optimal mechanism is incentive compatible, individually rational but computationally inefficient. We propose a class of approximation mechanisms and prove that the mechanisms are all incentive...
In order to improve the comprehensive defense capability of netted radar system while tracking the multi-targets cooperatively, a more reasonable evaluation indicator is required to evaluate the overall performance of the netted radar system. The new evaluation indicators for radar deployment and allocation in the netted radar management are proposed quantitatively in this paper. As they consist of...
Along with the globalization of business, the opportunities and challenges in franchise business are increased. In order to ensure that the franchise industry grows stably, it has been always an important topic to forecast the franchise performance accurately. Thus, this study aims at utilizing Grey prediction as an analyze methodology to estimate the performance of US's franchise industry in order...
This paper proposes a practical system of the fish size measurement which is effective and simple. Because the fry we measured is very small, the main technical problem when we measure the fish size is to measure accurately without hurting them. Although the live fish can be measured directly or after anesthesia, the fry will be damaged. So we present the system of fish size measurement without any...
Due to the light attenuation caused by absorption and scattering of sea water, the performance of underwater optical communication system is limited. Usually, the optical signals will be decayed severely in hundreds of meters and the waveforms are submerged in noise. To improve the signal-to-noise ratio (SNR), for traditional methods, most of the noise can be suppressed by filters based on classic...
Electrically conductive adhesive is a new type of environmentally interconnect material which can be used in electronic packaging to replace the traditional solders due to its advantages of simple applying process and low curing temperature.

In this paper, we obtain the reverse hypercontractive region for the pair of variables (X, Y) where X is a uniformly distributed binary random variable and Y (a ternary random variable) is obtained by passing X through a symmetric binary erasure channel (BEC), for a non-trivial range of parameters. The technique used builds on two recent results: a) characterization of reverse hypercontractivity using...
In this work a Cu paste consisting in both micro and nanoparticles was produced. The copper paste was produced with different additive weight percentages of Ag coated SiC and sintered for 30min at 500°C under 6,5MPa in N2 atmosphere. The thermal resistance and composition of the resulting joints was studied. XPS and EDX measurements show no significant oxidation of the Cu after sintering, which is...
