Cloud storage is a service provided by cloud service provider (CSP). More and more individuals and organizations accept the scheme and outsource their data to CSP seeking to reduce local storage burden. Since the outsourced files are no longer under the data owners' direct control and CSP is not trustworthy, it is necessary for data owners to check the integrity of their files outsourced to CSP. To...
In order to improve the accuracy of tracking the path and control the car velocity accurately on the hillside. The optimized fuzzy-PID control strategy is put forward and designed. On the platform of ATMEGA2560 microcontroller, the position of the car is adjusted by using the altitude algorithm constantly, and the optimal path strategy is carried out according to the optimized fuzzy-PID control algorithm,...
WE have previously demonstrated a stripline readout for TOFPET detectors that can achieve significant reduction in the number of readout channels while maintaining good detection performance [1-3]. The principle of this time-based multiplexing readout is depicted in Figs. 1(a) and 1(b). As shown, a stripline receives the outputs of several photodetectors (PD). When a PD produces a signal at time t...
We have developed a filtering method to reduce RF interference in PET data for simultaneously acquired PET-MR. Data was acquired from a SiPM-based PET detector coupled to LYSO scintillators using a transmission-line readout scheme and high-speed waveform sampling. The detector was placed within a 9.4 T small animal MR system with either copper or no shielding, and PET data from a low-activity 22Na...
As a novel fundamental platform for providing real time access to wireless network, vehicular communication is drawing more and more attentions in recent years. IEEE 802.11p is a main radio access technology which supports communication for high mobility terminals. Due to the limited coverage, it is usually deployed coupling with cellular network to achieve seamless mobility. In cellular/802.11p heterogeneous...
Vehicular communication, as a novel fundamental platform for providing wireless access, is drawing more and more attentions in recent years. IEEE 802.11p is a main radio access technology which supports communication for high mobility terminals. Due to the small coverage, road side unit (RSU) is usually deployed coupling with cellular network to achieve seamless mobility. In cellular/802.11p heterogeneous...
Metabolites can serve as biomarkers and their identification has significant importance in the study of biochemical reaction and signalling networks. Incorporating metabolic and gene expression data to reveal biochemical networks is a considerable challenge, which attracts a lot of attention in recent research. In this paper, we propose a promising approach to identify metabolic biomarkers through...
This paper proposes an ANFIS indoor positioning system based on improved genetic algorithm (GA). In the offline phase, fuzzy rules are abstracted by means of subtractive clustering algorithm with training data, generating the structure of each ANFIS positioning subsystem in X and Y directions. Then each positioning subsystem is trained with improved-GA. In this training algorithm, BP algorithm acts...
Calculates the envelope thermal characteristics of the Phase Change Material (PCM) lightweight building fabrics, such as the thermal inertia index, storage heat coefficient, delay time and attenuation ratio,ect. Comparing with the common lightweight building fabric the envelope thermal characteristics of the PCM lightweight building fabrics has been improved preferably. The thermal inertia index,...
With the motivation of high efficiency, energy saving and environmental protection, a solar LED lighting system was designed. The system implemented maximum power point tracking technology (MPPT) and precise three-section storage battery charging by charging control, which improves the utilization ratio and lifetime of solar cell, enhancing the energy conversion efficiency. The use of LED lighting...
Recent years have witnessed an increased interest in computing cosine similarities between documents (or commodities). Most previous studies require the specification of a minimum similarity threshold to perform cosine similarity search. However, it is usually difficult for users to provide an appropriate threshold in practice. Instead, in this paper, we propose to search top-K strongly related pairs...
An automatic target detection algorithm of SAR image based on parallel computing is presented in this paper. The experimental results based on constant false alarm rate detector verify that the algorithm adapts well to the parallel processing system with high performance and parallel efficiency. That means the algorithm has high real time property.
The ever-growing resources of information and services on World Wide Web provide a welcome boost for the researches in the information retrieval space. Text clustering groups a set of documents into subsets or clusters so that the vast retrieved documents can be browsed selectively and efficiently. Many cluster validation measures, such as the F-measure, are then introduced to evaluate the clustering...
A new kind of oil-mist collection is design to reduce the harm of oil-mist produced by cold-former to people and environment. This paper stimulates the flow field of oil-mist cooling and separation device by using Fluent and obtains the speed vector by adopting the standard К - ε turbulence model and supplying air from different speed. It is validated that the device is a perfect part of the oil-mist...
On purpose of analyzing the key-part sensitivity and stability of an online thickness measuring system, the PSD analysis method based on FEM model is used to obtain the displacement, velocity and acceleration response results of the key-part. The analysis results proved that it is effective to use the PSD analysis method on the elastic vibrating part response analysis.
