In order to detect the obstructive sleep apnea (OSA) accurately, a non-contact way using Doppler radar is presented in this paper. The residual comparison based algorithm has been proposed to enhance the body movement cancellation and pre-event baseline calculation, so that the OSA event can be detected accurately. The experimental result shows the effectiveness of the proposed method for diagnosing...
With the high-speed railway put into operation, the types of trains in the existed line is reduced, train intervals will also be shortened. We analyze the impact of high-speed rail's operations on the basis of the calculation method of the interval passing capacity in existed line, for example in three major areas : the difference of train running time in the section, the proportion of trains dispatched...
We evaluate the on-node interference caused when co-locating traditional high-performance computing applications with a big-data application. Using kernel benchmarks from the NPB suite and a state-of-art graph analytics code, we explore different process placements and effects they have on application performance. Our results show that the most memory intensive HPC application (MG) experienced the...
Internet of vehicles (IoVs) emerges as a promising technology to facilitate vehicular wireless communication by approving vehicle-to-everything (V2X) services for intelligent transportation systems including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-pedestrian (V2P) services. V2V networks have been rapidly developed to support short distance data transmission among vehicles...
In order to enable the development of smart services, many IoT platforms were proposed to securely and reliably connect IoT devices to the Internet and to each other. Examples are IoTivity from Open Connectivity Foundation (OCF), AllJoyn from AllSeen Alliance, Weave from Google and HomeKit from Apple. However, such fragmentation of IoT platforms has made the development of IoT applications very difficult...
Nowadays the adoption of IoT solutions is gaining high momentum in several fields, including energy, home and environment monitoring, transportation, and manufacturing. However, cybersecurity attacks to low-cost end-user devices can severely undermine the expected deployment of IoT solutions in a broad range of scenarios. To face these challenges, emerging software-based networking features can introduce...
Process of detailed testing and verification of all automotive embedded software components generates detailed reports about each segment of tested electronic control units (ECU). The very first group of tests in this process is Acceptance tests, and one of the most important tests in this stage of testing and verification is interface check of the software component. The interface check must ensure...
The Ecuadorian electricity sector is a strategic area of the country, whose general objective is to Generate, Transmit, Distribute and Commercialize electrical energy. In 2009, the Ministry of Electricity and Renewable Energy (MEER) and the Electric Utilities of Ecuador signed an agreement for institutional cooperation to strengthen the electricity distribution sector with the objective of achieving...
The predictive proportional integral (PPI) controller being simple and non conservative like its Smith predictor and internal model control (IMC) counterparts, has the ability to be employed in environments characterised by uncertainties such as stochastic network delays. However, its performance degrades in the presence of measurement noise. This is due to the prediction involve in the controller...
Nowadays, QR (quick-response) codes have become part of our daily life. In many applications, QR codes are posted (i.e. pasted or printed) on cylinders. Then, the QR image as captured by a camera would be distorted. In this paper, we try to tackle the decoding of QR codes in such a situation. It is based on perspective projection (PP), which is specified by a camera matrix (cM), with the assistance...
YouTube is one of the comprehensive video information source on the web where video is uploading continuously in real time. It is one of the most popular site in social media, where users interact with sharing, commenting and rating (like/views) videos. Generally the quality, relevancy and popularity of the video is maintained based on this rating. Sometimes irrelevant and low quality videos ranked...
Ontology Matching is a process to find correspondences between semantically related entities of two ontologies. Most matching systems do evaluation by comparing the correspondences with reference alignment. Since 2010 another method has been used to measure a logic-based of correspondence or mapping, called incoherent mapping measurement. The more incoherent of the mapping the lower quality of mapping...
With the development of automated lighting systems, accent lighting is undergoing a major transformation with the adoption of LED light sources. Movable spot luminaires are generally used for their beam effect and the ability to project texture. Spot luminaire units are controlled in many ways. This paper focuses on using DALI (Digital Addressable Lighting Interface) for controlling light and motors...
Can machine learning prove useful in deciding sociological questions that are difficult for humans to judge impartially? We propose that it can, and even simple methods can be useful for evaluating evidence with reduced influence from human bias. Our case study is intelligent design (ID) social media, particularly the detection of religious content therein. Being a polarizing topic, critics of intelligent...
In this paper we explore the hybrid application of evolutionary computation and artificial neural networks in the development of intelligent systems able to solve the problem of approximating the optimal strategy in a tile-matching puzzle game. Three intelligent systems are proposed: an evolutionary heuristic technique, artificial neural networks, and a hybrid approach that combines both. Results...
This paper describe the implementation of a lock-in amplifier (LIA) which conforms to the AXI standard for on-chip communication. The design and implementation is based on the Zynq field programmable gate array (FPGA) present in the open-source instrument RedPitaya. The designed architecture is a mixed solution between VHDL hardware modules and software modules, running within an ARM CPU. General...
Multi-view subspace clustering aims to partition a set of multi-source data into their underlying groups. To boost the performance of multi-view clustering, numerous subspace learning algorithms have been developed in recent years, but with rare exploitation of the representation complementarity between different views as well as the indicator consistency among the representations, let alone considering...
Nowadays, one standard therapy for advanced heart failure is the implantation of left ventricular assist devices (LVAD). The LVAD is a mechanical pump, which supports the heart to pump blood to the rest of the body. However, there are serious complications including pump thrombosis. Pump thrombosis is a formation of blood clot inside the LVAD pump, which can result in pump stop and worst case leads...
The Compressed Sensing (CS) framework is heavily utilized to reduce data rate in hardware restricted scenarios by exploiting the intrinsic sparsity of the transmitted data. Considering multiple sensors at the same time, one variation of the Multi Channel (MC) framework takes several measurements at one time instant and then uses CS in the spatial domain to compress the data. This paper provides a...
