Electrical resistivity is a nondestructive testing (NDT) method, which shows continuously the physical and chemical behaviors in each hydration stage and reflects the microstructure characteristics or transport properties of the cement matrix. In this letter, a self-developed embedded sensor is investigated and applied to predict the compressive strength of cement paste by the electrochemical impedance spectroscopy. The compressive strength prediction model is presented as the function of early compressive strength and electrical resistivity within 24 h. It demonstrated that the electrical resistivity can be taken as an equivalent index to evaluate the compressive strength. This self-developed embedded sensor could be applied in the health monitoring system for smart buildings.

Fetal distress is the main cause of frequent adverse events such as asphyxia and disability. It is particularly important to monitor the fetal intrauterine state in late pregnancy so as to detect fetal abnormalities in time. Cardiotocography (CTG) is an important tool for fetal health assessment in clinical practice. But the accuracy and consistency of CTG are generally not ideal as the correct interpretation is affected by the doctor's clinical experience and ability. Therefore, this paper proposed an intelligent assistant diagnosis algorithm based on fetal heart rate (FHR) signals, which integrated by the input layer construction based on MelFrequency Cepstral Coefficients (MFCCs) and the deep neural network model based on bidirectional long short-term memory (BLSTM). Through 200 sets of intrapartum data from a public database, the results show that the proposed algorithm achieves a high accuracy of 96.25%, which can achieve a pretty well assessment of the fetal state and assist clinicians to make an auxiliary diagnosis of the fetal health.

Mango (M. indica cv. Datainong) fruit quality rapid determination method based on electronic nose (E-nose) was investigated in this research. E-nose responses to mangoes stored at room temperature were examined for 9 days. Meanwhile, physicochemical and microbiological indexes including firmness, weight loss, surface colour, yellowing rate, pH, total soluble solids, polyphenol oxidase activity and total viable counts were measured to provide quality references for E-nose analysis. Principal component analysis (PCA) and stochastic resonance (SR) were utilized for E-nose data analysis. Results indicated that mango fruit quality decreased sharply during storage. PCA just allowed qualitative quality discrimination, while SNR spectrum using eigen values successfully characterized mango quality. Mango quality predictive model was developed by linear fitting SR eigen values. Validation experiment results demonstrated that the forecasting accuracy of the developed model reached 90%.

PERC solar cell passivated on the backside with AlOx and SiNx was introduced to construct the perovskite/silicon four-terminal tandem solar cell, because of its outstanding spectral response at the long wavelength region and much lower cost than SHJ and IBC. Different from the vast majority of the related reports, which were focused on the improvement of perovskite top cell, the silicon bottom cell was optimized here to promote the tandem efficiency. The central wavelength of antireflection was adjusted to further reduce the reflectance and enhance the spectral response of PERC cell in long wavelengths, in order to make the most of long-wavelength light transmitted through the perovskite top cell. Along with the increase of central wavelength, the external quantum efficiency of PERC cell at near-infrared wavelengths increases resulting in better short circuit current density and photoelectric conversion efficiency when filtered by the perovskite cell. A tandem efficiency gain of 0.07% (abs.) has been achieved. This report provides a facile way to improve the efficiency of perovskite/silicon four-terminal tandem solar cell based on the optimization of long-wavelength spectral response.

With the rapid development of high-resolution remote sensing camera and the rapid increase of the number of remote sensors, telemetry data and image data have the characteristics of large amount of concurrency and high real-time. These characteristics bring great challenges to the test, interpretation and processing of massive data, which requires a lot of manpower and time resources, meanwhile, it is easy to cause repeated test work because of the errors occur during operations and interpretations. In order to improve work efficiency, test coverage, test accuracy, comprehensiveness, and human resources, developing automatic and intelligent test equipment is becoming much more particularly urgent and necessary. The test system proposed in this paper uses the on-line monitoring and diagnosis system to analyse the running state of the equipment in real time, find out the system fault in time, locate and eliminate it. The system can put forward the network protocol of data processing and storage, command control, real-time analysis and transmission of telemetry information and display the realization way of the test system workflow. It is expected that the system test efficiency will be increased by more than 5 times. In addition, the efficiency of fault diagnosis and data processing will be increased by more than 3 times. The automatic test system can solve the conflicts between test quality and human resources, moreover, the architecture patterns based on Ethernet is easy to expand and reconstruct.

This paper focuses on the contribution of the global positioning system (GPS) and BeiDou navigation satellite system (BDS) observations to precise point positioning (PPP) ambiguity resolution (AR). A GPS + BDS fractional cycle bias (FCB) estimation method and a PPP AR model were developed using integrated GPS and BDS observations. For FCB estimation, the GPS + BDS combined PPP float solutions of the globally distributed IGS MGEX were first performed. When integrating GPS observations, the BDS ambiguities can be precisely estimated with less than four tracked BDS satellites. The FCBs of both GPS and BDS satellites can then be estimated from these precise ambiguities. For the GPS + BDS combined AR, one GPS and one BDS IGSO or MEO satellite were first chosen as the reference satellite for GPS and BDS, respectively, to form inner-system single-differenced ambiguities. The single-differenced GPS and BDS ambiguities were then fused by partial ambiguity resolution to increase the possibility of fixing a subset of decorrelated ambiguities with high confidence. To verify the correctness of the FCB estimation and the effectiveness of the GPS + BDS PPP AR, data recorded from about 75 IGS MGEX stations during the period of DOY 123-151 (May 3 to May 31) in 2015 were used for validation. Data were processed with three strategies: BDS-only AR, GPS-only AR and GPS + BDS AR. Numerous experimental results show that the time to first fix (TTFF) is longer than 6 h for the BDS AR in general and that the fixing rate is usually less than 35 % for both static and kinematic PPP. An average TTFF of 21.7 min and 33.6 min together with a fixing rate of 98.6 and 97.0 % in static and kinematic PPP, respectively, can be achieved for GPS-only ambiguity fixing. For the combined GPS + BDS AR, the average TTFF can be shortened to 16.9 min and 24.6 min and the fixing rate can be increased to 99.5 and 99.0 % in static and kinematic PPP, respectively. Results also show that GPS + BDS PPP AR outperforms single-system PPP AR in terms of convergence time and position accuracy.

Laser-induced deterioration was proposed for the wet grinding of zirconium oxide (ZrO 2 ) ceramic used in the dental, semiconductor and automotive industries. The mechanisms for laser induced deterioration and wet grinding of the deterioration layer were theoretically analysed, and the four key processing parameters that determine the micro-topography and distribution of the laser-induced crater were proposed, including the laser power density I p , the defocus distance z, the laser spot overlap ratio U s and the laser scanning track line overlap ratio U l . Further, the forming mechanism of the single pulse-induced crater under different laser power densities, the defocus distance, and the interaction mechanisms between adjacent spots along the longitudinal and transverse directions were investigated. The optimal values of the key processing parameters were identified. To further evaluate the effect of laser-induced deterioration objectively, a comparative experiment was conducted under laser-induced deterioration wet grinding (LIDWG) and conventional grinding (CG) conditions. It was found that the procedure of laser-induced deterioration had a strong influence on the grinding results. The normal and tangential grinding forces for LIDWG condition were lower than for CG condition, with a maximum reduction of 59.2 % (62.9 %). Kljub vse večjemu povpraševanju po izdelkih iz cirkonijevega dioksida je širjenje uporabe omejeno zaradi majhnih stopenj odvzema materiala in visokih stroškov obdelave, ki presegajo 75 % stroška komponente. Razrešitev težav, povezanih z natančnostjo in učinkovitostjo obdelave keramike ZrO2, je zato pomembna za proizvodno industrijo. Za tradicionalno lasersko podprto brušenje (LAG) so značilne omejene možnosti uporabe hladilne tekočine in površinske/podpovršinske razpoke, ki se tvorijo zaradi akumulacije toplote. Te težave predstavljajo ozko grlo pri praktični uporabi LAG in zato je predlagana nova strategija za lasersko pripravo površine keramike ZrO2 na mokro brušenje (LIDWG). Cilj LIDWG je nadzorovano poškodovanje vrhnje plasti v enakomernih vzorcih kot priprava na visokoučinkovito brušenje. Proces LIDGW je sestavljen iz dveh različnih podprocesov: priprave in brušenja.

Background Overexpression of apolipoprotein CIII (ApoCIII) leads to hypertriglyceridemia (HTG) which promotes atherosclerosis development. However, it remains unclear whether ApoCIII affects the atherosclerosis alone by promoting the inflammation and endoplasmic reticulum (ER) stress, or in combination with HTG. Methods Transgenic (ApoCIIItg) mouse models were used to investigate the atherogenic role of ApoCIII. Since endothelial cells and macrophages play crucial roles in atherosclerosis, we examined whether triglyceride-rich lipoproteins (TRLs), the major lipoproteins, in plasma of ApoCIIItg mice affect inflammation and ER stress levels in these cells. To further investigate the role of ApoCIII and triglyceride, we incubated HUVECs cells and peritoneal macrophages with TRLs with or without ApoCIII. Results Increased inflammation and ER stress were found in the aorta of ApoCIIItg mice. TRLs increased ER stress and oxidative stress in HUVECs and macrophages in a dose dependent. Moreover, TRLs together with ApoCIII could induce a higher inflammation level than TRLs alone in these cells. Conclusions Both TRLs and ApoCIII contribute to the progression of atherosclerosis, and the modulation of TRLs and ApoCIII may represent a novel therapeutic approach against HTG induced atherosclerosis.

Through simulation with PC1D software, it comes to a conclusion that low reflectance is essential to realize better photovoltaic performance, especially Jsc. Therefore, MACE texturing technology and double-layer antireflection coating were employed to reduce the reflectance of DWS polycrystalline silicon wafer. In order to inhibit the higher surface recombination velocity induced by submicrostructure texture, thermally grown oxide was introduced to enhance the passivation quality of SiNx:H. Finally, compared with the solar cell fabricated with traditional acid-based etching method, an efficiency gain of up to 0.49% (abs.) has been achieved.

The applications of photonics defined radio are also discussed in brief.

Arrhythmogenic right ventricular cardiomyopathy is characterised by progressive, fibrofatty replacement of myocardium, and ventricular arrhythmias, and its prognosis is usually poor. Arrhythmogenic right ventricular cardiomyopathy associated with atrial septal defect is very rare, and this combination may make the diagnosis, treatment, and prognosis difficult. We present a case of a patient with this association who underwent interventional treatment with a septal defect occluder. Transcatheter closure of atrial septal defect in a patient with arrhythmogenic right ventricular cardiomyopathy is hitherto unreported. During a 3-year follow-up he remained relatively stable. We also review the cases reported in the medical literature describing this uncommon association between arrhythmogenic right ventricular cardiomyopathy and atrial septal defect or patent foramen ovale.

The clocking effect, known as a potential means to improve the aerodynamic performance of the turbomachinery, has been investigated widely in the multistage axial turbomachinery, but little reported on the radial turbomachinery. In the present paper, an experimental investigation was made on the vane clocking effect between the inlet guide vanes and the vaned diffuser in a medium-speed centrifugal compressor. The measured data show that the vane clocking has an effect on the aerodynamic performance of the researched centrifugal compressor stage. At the design point, the maximum efficiency variation is about 0.52 points and the maximum total pressure ratio variation is 0.004. When the inlet guide vane’s stagger angle was adjusted to −45°, the vane clocking effect is strengthened. The maximum efficiency and total pressure ratio variation for the design point, respectively, are 0.67 points and 0.006, and for the low flow rate point even, respectively, increases to 0.90 points and 0.007. The wake characteristics show that the maximum efficiency variation always arises at a similar clocking configuration, in which the upstream inlet guide vanes wake was detected to impinge on the diffuser blade leading edge. In addition, the profile pressure distribution on the diffuser blade was measured in detail and the blade loading analysis shows that there is no measureable variation for the vane clocking effect on the steady diffuser blade loading.

To meet the exponentially growing demand for bandwidth in Optical Transport Networks (OTNs), 100-Gb/s (100G) coherent technology based on Polarization-Division Multiplexed Quadrature Phase Shift Keying (PDM-QPSK), which enables the capacity of a Wavelength Division Multiplexing (WDM) system to approach 10 Tb/s, is being widely deployed globally. As the first vendor to introduce a single-carrier 100G solution, Alcatel-Lucent has developed key transponder and network management technologies, which are reviewed in this paper together with their commercial evolution to 400G. Focusing on the Chinese market, we also review some key bench-mark testing results obtained in partnership with major Chinese operators. Finally, we discuss enabling technologies that are currently being researched to allow interfaces to scale to Terabit/s rates.

Case Based Reasoning (CBR) is a novel paradigm that uses previous cases to solve new, unseen and different problems. However, redundant features may not only dramatically increase the case memory, but also make the case retrieval more time-consuming. In order to enhance the processing accuracy, the surface quality and the processing efficiency of laser assisted machining (LAM) of Al2O3 ceramics, a processing parameters selection was proposed. By test analysis, optimizing process parameters scope can be obtained. Such as laser power is 260 ~ 290 w, cutting depth of 0.32 ~ 0.5 mm, workpiece speed of 186 ~ 398 r/min, feed rate for 0.12 ~ 0.15 mm/r.

The concept of dual hesitant fuzzy sets (DHFSs), which was first introduced as a new extension of fuzzy sets and hesitant fuzzy sets in 2012, is a useful tool to deal with the vagueness and ambiguity in many practical problems under hesitant fuzzy environment. Normally, we use the definition of distance to describe the relationship of two DHFSs. However, considering that the existing distance measures of DHFSs still have some major shortcomings, so in this paper, we firstly introduce a new concept –hesitance degree of each dual hesitant fuzzy element (DHFE) to these existing distance measures and then develop several novel distance measures in which both the values and the numbers of values of DHFE are taken into account. The properties of these new distance measures are discussed. Finally, we apply our proposed distance measures of DHFSs in pattern recognition making to illustrate their validity and applicability.

The main activities in the joint expedition between CHINARE and ANARE on Amery ice shelf are introduced. Five-day continuous GPS observation data collected on the site which locates at the frontal part of Amery ice shelf was processed with precise point positioning (PPP) technology based on precise products from IGS. Velocity of the surface ice flow on Amery can be derived from the PPP solution. Preliminary result shows that the surface ice flow velocity of the site is 2.25 meters per day, the motion direction is northeast-ward. Semidiurnal oceanic tide and diurnal oceanic tide signal of that site can be recovered from the height variation series of PPP solution. These above solutions can be used to the consequent mass balance calculation.

The error sources related to the laser rangefinder, GPS and INS are analyzed in details. Several coordinates systems used in airborne laser scanning are set up, and then the basic formula of system is given. This paper emphasizes on discussing the kinematic offset correction between GPS antenna phase center and laser fired point. And kinematic time delay influence on laser footprint position, the ranging errors, positioning errors, attitude errors and integration errors of the system are also explored. Finally, the result shows that the kinematic time delay can be neglected as compared with other error sources. The accuracy of the coordinates is not only influenced by the amplitude of the error, but also controlled by the operation parameters such as flight height, scanning angle amplitude and attitude magnitude of the platform.

In this paper, over complete independent component analysis (Over complere ICA) is solved using discrete wavelet transform based parallel architecture, which is a combined system consisting of two sub-over complete ICA. One process takes the high-frequency wavelet part of observasions as it's inputs and the other process takes the low-frequency part, then the final results are generated by merged their results. The proposed method utilizes the full obversation information compared to the existing over complete ICA algorithms, but the effective input length of the two parallel process is halved. Therefore a method is provided for over complete ICA problems and the experimental results in this paper indicates it's good performance for separating the mixed speech signals.

Insulation failure is one of the major causes of catastrophic failure of high voltage apparatus. It is important for the study of partial discharge behavior in electrical apparatus to know the degration of insulating materials. This paper focuses on the analysis of acoustic signal produced by partial discharge in insulation oil. The needle-plane electrode system is assembled to simulate the partial discharge in insulation oil. Wavelet transform is used to analyze acoustic signal. The energy distribution of each level and time domain waveform is analyzed. A low-noise amplifier and a de-coupler are used to detect the acoustic signal with high-sensitivity. A digital acquire card is used to get the acoustic signal and save data in computer.

This study is a meta-analysis of the efficacy and safety of the application of adjuvant material in the repair of anterior vaginal wall prolapse and a sub-category analysis of the use of nonabsorbable synthetic mesh, biological graft and absorbable synthetic mesh.Pubmed, Embase and Ovid databases were searched for published randomized controlled trials from 1980 to February 2012 on the treatment of anterior vaginal wall prolapse with adjuvant materials. A comprehensive meta-analysis applying Revman5.1 analysis software was performed.A total of 20 randomized controlled trials including 2,313 participants were recognized. The result showed that repair with adjuvant materials was better and more effective; nevertheless, use of adjuvant materials resulted in longer duration of surgery and more peri-operative bleeding when compared with the control group, but no significant differences were observed between the two groups regarding visceral injury, postoperative pain, urinary tract infection rate, new stress incontinence and new dyspareunia.Adjuvant material is worthy of clinical popularization, especially the biological graft type because of its lower anatomy failure rate and no difference in safety compared with the control group. However, exposure to adjuvant materials and erosion rate are high, which are the most important aspects to be improved.

The network-based real-time kinematic (RTK) positioning has been widely used for high-accuracy applications. However, the precise point positioning (PPP) technique can also achieve centimeter to decimeter kinematic positioning accuracy without restriction of inter-station distances but is not as popular as network RTK for real-time engineering applications. Typically, PPP requires a long initialization time and continuous satellite signals to maintain the high accuracy. In case of phase breaks or loss of signals, re-initialization is usually required. An approach of instantaneous cycle slips fixing using undifferenced carrier phase measurements is proposed, which leads to instantaneous re-initialization for real-time PPP. In the proposed approach, various errors such as real-time orbit and clock errors, atmosphere delay and wind-up effects are first refined and isolated from integer cycle slips. The integer values of cycle slips can then be estimated and fixed with the LAMBDA technique by applying a cascade cycle slip resolution strategy. Numerical experiments with different user dynamics are carried out to allow a comprehensive evaluation of efficiency and robustness of the cycle slip fixing algorithm. The results show that the cycle slips can be fixed correctly in all cases considered and that data gaps of up to 300 s can be connected with high confidence. As a result, instantaneous re-initialization is achieved in the real-time PPP processing.

Most existing methods of Web data extraction realize goals based on DOM tree analysis or wrapper building. However, applicability and efficiency of these methods need to be further improved. According to the amount of information, Web pages will be divided into two structure types which are 1:1 and 1:N type respectively. As same type of Web pages has similar structure features, the paper proposes an approach of two-phase Web data extraction base on structure feature. In the phase of samples learning, structure feature and depository rules of Web pages are obtained according to the text feature of sample pages. In the phase of information extraction, Web data extraction is implemented by matching the page to be extracted with depository rules in knowledge base. Experimental results show that the approach proposed in the paper has well applicability and high efficiency.

Objectives: To better realize the features of peripheral blood (PB), bone marrow (BM) aspirate and especially BM trephine biopsy in atypical chronic myeloid leukemia (aCML). Methods: We studied PB, BM smears in 35 cases of aCML and compared with 84 cases of chronic granulocytic leukemia chronic phase (CGL-CP), 39 cases of chronic myelomonocytic leukemia (CMML). In addition, we evaluated characteristics of BM trephine biopsies in 21 cases of aCML and compared with 68 cases of CGL-CP, 20 cases of CMML. Results: All aCML patients presented with leukocytosis (median WBC 17.3 × 109/L), 48% had moderate anemia, and 85% had thrombocytopenia. Values of monocytes, eosinophils, basophils, percentage of immature granulocytes and monocytes (0.63 ± 0.41 × 109/L, 0.18 ± 0.16 × 109/L, 0.09 ±0.08 × 109/L, 6.27 ± 3.09%, and 2.46 ± 1.75%, respectively) were useful in distinguishing aCML from CGL-CP and CMML groups. The BM smears showed that striking dysgranulopoieis (100%), dyserythropoiesis (48.6%), percentage of blasts, nucleated erythrocytes, monocytes, eosinophils, and basophils (2.45 ± 2.06%, 7.76 ± 2.89%, 1.30 ± 1.21%, 1.47 ± 1.60%, and 1.15 ± 1.08%, respectively) were all important parameters for a diagnosis of aCML. On BM trephine sections, aCML was characterized as hypercellularity, a moderate degree of reticulin fibrosis (71.4%), lymphocytopenia (76.2%), plasmacytopenia (90.5%), abnormal localization of immature precursors (28.5%), and absence of eosinophilia, basophilia, monocytosis. Furthermore, BM imprints, immunohistochemical, and cytochemical staining findings provided important morphological reference to BM trephine sections and made the identification of nucleated cells more convenient. Conclusions: Besides the findings observed in PB and BM aspirate, features of BM trephine biopsy (including BM trephine section, BM imprint, immunohistochemical, and cytochemical staining) can also aid in the diagnosis of aCML.

Now the tourism information is overflow in the internet, but the useful information is had to find out. So, it takes the recommendation technology in common use as the research object, and adopts the comparison method to study different recommendation technologies, such as the association rules, collaborative filtering and item-based recommendation.

Stability of capacity is one of the key properties for quality of service (QoS) support in mobile ad hoc networks (MANETs). In this paper, a novel technique is proposed for controlling the stability of capacity analysis model for non-cooperative program game MANETs, with the time-varying propagation delay taken into consideration. First, based on the obtained source node flow transmitting rate evolution aligns of capacity analysis model for non-cooperative program game mobile ad-hoc network, when adding the time-varying propagation delay term, which is a class of nonlinear time-varying delay differential aligns, the asymptotic stability criteria of the model are presented in the form of descriptor and linear matrix inequalities. Then, an iterative algorithm is also provided for controlling the stability of the model. The proposed criteria are less conservative since they are based on an equivalent model transformation. Simulation experiments verify the effectiveness of this algorithm. Although the model used in this paper focuses on a specific algorithm, we believe that this method has a great potential in analyzing and understanding the general capacity of MANETs stability control issues.
