Multilayer network analysis has become a vital tool for understanding different relationships and their interactions in a complex system, where each layer in a multilayer network depicts the topological structure of a group of nodes corresponding to a particular relationship. The interactions among different layers imply how the interplay of different relations on the topology of each layer. For a...
The success of deep neural networks usually relies on a large number of labeled training samples, which unfortunately are not easy to obtain in practice. Unsupervised domain adaptation focuses on the problem where there is no labeled data in the target domain. In this paper, we propose a novel deep unsupervised domain adaptation method that learns transferable features. Different from most existing...
Ecological inference (EI) is a classical problem from political science to model voting behavior of individuals given only aggregate election results. Flaxman et al. recently formulated EI as machine learning problem using distribution regression, and applied it to analyze US presidential elections. However, distribution regression unnecessarily aggregates individual-level covariates available from...
Obesity is increasing globally and is a risk factor for many chronic conditions such as such as heart disease, sleep apnea, type-2 diabetes, and some cancers. Research shows that food logging is beneficial in promoting weight loss. Crowdsourcing has also been used in promoting dietary feedback for food logging. This work investigates the feasibility of crowdsourcing to provide support in accurately...
The methodology of community detection can be divided into two principles: imposing a network model on a given graph, or optimizing a designed objective function. The former provides guarantees on theoretical detectability but falls short when the graph is inconsistent with the underlying model. The latter is model-free but fails to provide quality assurance for the detected communities. In this paper,...
Recently, with China's economic development into a new normal state, slow growth of the power demand and rapid expansion of new energy sources puts coal-fired power at excess risk in the short term. For Anhui Province, a coal-based province, more attention should be paid to the development direction of future coal-fired power. Considering the prospect of coal-fired power development in China and the...
This paper evaluates the impact of local government capital investment subsidies for the installation and the price of rooftop solar photovoltaic (PV) system in Japan. By creating the micro-level unique panel dataset covering the period between 2009 and 2014, we compared municipalities that employed subsidies with municipalities that did not to analyze their effects on the amount of installation and...
The increasing trend of people moving to urban areas and the associated urbanization process require facing challenges regarding city infrastructures capability to cover citizens needs for energy, water, transportation, healthcare. education, safety. The smart urban technologies represent an important contribution to the sustainable development of cities, making smart cities a reality. The concept...
This paper is devoted to the analysis and research of methods for encoding BMP images using the Haar wavelet, as well as parallel programming and the development of parallel pixel processing algorithms based on the OpenMP standard.
In the present work, a 2D numerical study, using the k-ε Standard and k-ε EARSM turbulence models, has been carried out to determine which turbulence model better predicts the performance of the experimental Darrieus turbine test model. The computational fluid dynamics (CFD) was done for a vertical water Darrieus turbine (VAHT), with three NACA0020 straight blades, rotating at five different RPM (96,...
The Trustful Space-Time Protocol (TSTP) allows for time synchronization to be performed upon receiving any message from another node in a sensor network, removing the need for explicit synchronization messages. Previous work has shown that TSTP performs well under controlled experimental environments. In this work, we analyze how the quality of synchronization in TSTP is affected when nodes are communicating...
This paper proposes an algorithm that uses predefined weights to create broadcast routes for a WirelessHART network. The network topology is represented by a graph, and the algorithm uses information of the devices present in the network to build the broadcast graph. At each iteration of the algorithm, a device is selected and then added to the broadcast solution graph. A cost function determines...
Provided by Google, Eddystone standard consists of a beacon technology, open-source format, unidirectional and proximity-based Bluetooth® Low Energy (BLE) standard. Eddystone can support multiple different payloads, portable for IOS and Android with a ranging of approximately 50 meters. This paper analyses different metrics of a Verilog digital logical implementation of a Google Eddystone...
In this paper, an implicit iterative algorithm is developed to obtain the unique positive definite solution of the generalized algebraic Riccati matrix equation. For this proposed algorithm, there exisits a tuning parameter which can be chosen such that this algorithm achieves better convergence performance. Some convergence results are given for the proposed algorithm. Moreover, an approach is also...
The existence of non-line-of-sight (NLOS) errors will considerably degrade the localization accuracy. Therefore, the NLOS node localization is investigated. In this article, we propose a NLOS node localization algorithm that utilizes the firefly algorithm. The objective function is established by the probability of propagation of NLOS and LOS according to the approximate maximum likelihood method...
In this paper, study the influence of anti-stripping agent on the mesoscopic strength of basalt asphalt mixture in seasonal frozen region under different states and temperatures by experiments. Meanwhile Accurately and objectively evaluate the characteristics on engineering performance of two kinds anti-stripping agents. Results show that anti-stripping agent improves the mesoscopic strength of basalt...
Fiber optic end face inspection microscopes must provide consistent results to obtain agreement on product quality throughout the supply chain. Chrome on glass artifacts, with defect diameters spanning the range of interest, were shown to provide quantitative measurement of the reproducibility across multiple FastMT scopes.
Multi-access stable radio frequency phase dissemination for 100 km fiber-optic loop link is achieved based on single optical source. Phase jitter of 2.4 GHz signal at the accessing node is reduced to 1.57 ps/1.76 ps.
Significant steps towards improved design and deployment of Wavelength Division Multiplexed (WDM) networks and architectures for aircraft and ships are described, focusing on a practical, MS Excel®-based, detailed and comprehensive optical network design Cost Model. We also describe recent progress in related SAE International WDM LAN standards that define the standard Optical Network Elements (ONE)...
In the present day, industry has been brought closer to the Industry 4.0 paradigm due to its needs of reaching better industrial communications and improving the control process. According to the IIoT concepts, Cyber Physical Production Systems (CPPS) are normally connected to each other, and also connected to the virtual world of global digital networks. By introducing the IEC-61499 standard, CPPS...
