With the rapid development of portable electronics, such as e-paper and other flexible devices, power sources with a high flexibility become an important prerequisite. In this run, supercapacitors with a small form factor are recently emerging as a competitive candidate. Here, we introduce an all-printed paper based supercapacitor (PPS) assembled by screen printing and stencil printing technology,...
We experimentally demonstrate a polarization multiplexed RoF system with 2×2 MIMO wireless link using OFDM/OQAM technique. By using interference-cancellation-based channel estimator, 4.4 Gb/s 16QAM-OFDM/OQAM signal has been successfully transmitted over 25km SSMF and 0.4m air distance.
To reduce OBI noises in N-dimensional-CAP-PON uplink transmission over a single wavelength, a novel technique based on OLT-side coherent detection and DSP algorithm is proposed. 10Gb/s CAP-PON uplink transmission over 50-km-SSMF is also experimentally demonstrated.
We first compare the performance of the diffusion-based molecular communication (DMC) systems employing respectively the on-off keying (OOK), whose demodulation depends on a non-zero threshold, and the binary molecular shift keying (BMSK). Our studies demonstrate that the OOK is hard to operate in practical DMC environments, while the BMSK is more feasible for implementation in practice. Furthermore,...
The paper studies the applicability of a probabilistic data structure known as Bloom Filter (BF) in the content analysis component of Data Loss Prevention (DLP) Systems. The study shows that Bus may serve as preliminary selection mechanism in content analysis. The goal of such mechanism is to quickly pre-select documents that may be similar to the one being checked. This selection should be accompanied...
Lacking trusted central authority, distributed systems have received serious security threats from Sybil attack, where an adversary forges identities of more than one node and attempts to control the system. By utilizing the real-world trust relationships between users, social network-based defense schemes have been proposed to mitigate the impact of Sybil attacks. These solutions are mostly built...
Criterion, standard and policy of Korean language have played a very important role as Autonomy regulations in many aspects, especially input standards of computer using Korean language. So it is very necessary to invest to establish the standard of language information technology.
The vibration induced by blasting operation is one of the leading factors of waste dump stability near the open-pit, also the critical value of vibration velocity plays an important role in the waste dump stability evaluation. At present, the blasting vibration in waste dump dose not gain enough attention, and there is not vibration empiric formula in waste dump design specifications. By analysis...
Batch experiments were conducted to investigate the adsorption behavior of triclosan (TCS) at μg/L level in activated sludge. Effects of time, temperature, and MLSS on adsorption behavior were studied, and adsorption isotherm and thermodynamic parameters were studied as well. Sorption of TCS on the sludge was found to be physics-sorption, and partitioning played a significant role. TCS sorption process...
Sorption experiments of triclosan (TCS) were carried out on different sludge (anaerobic, aerobic and anoxic sludge) in different type (activated sludge, sterilized sludge and antibacterial sludge). The sorption models under different temperatures (10, 20 and 30°C) were investigated and the corresponding sorption coefficients were calculated. The results showed that TCS sorption agree with the Freundlich...
The structural morphology and spectra characteristic of ofloxacin (OFL) was strongly affected by the pH. In strong acidic solutions, OFL molecule exists as strong cation to achieve a weaker intensity. When the pH value increased to 3-4, OFL molecule exists as zwitterions, which is the strongest fluorescence form to have maximum intensity; the maximum exciting and emission wavelength of OFL were 298...
Based on datum from 1990 to 2008 of Liaoning province, by exerting stepwise regression, co-integration and error correction model, the paper analyzes the influential factors of FDI from different angles, such as market size, labor costs, degree of openness, human capital, and level of information. The results show that market size is the most important factor which influence FDI in Liaoning, meanwhile...
The scientific evaluation of water resources and the effective development and rational utilization of water resources are order to achieve coordinated development among regional economy, environment and society, and to meet different water departments' needs for the water resource in immediate and long-term different times. In this paper, based on matter-element theory model, the author evaluated...
Food quality and safety supervision department plays a pivotal role for the quality assurance in entire food supply chain. But the food safety supervision agency is an economic man, in the case of asymmetric information with the lack of supervision, If the punishment is not strict, food safety supervision department with information superiority may collusion together with agents to deceive the client...
Due to the perfect management of hospital information system, the hospital staff could draw a better heal scheme for patients with the whole information when they take care of them. And hospital information in the medical environment has also played a key to the role to make patient have a convenient and efficient medical environment. These are the strong protection for the hospital flinty competition...
This paper proposed a method for modelling of power system fault diagnosis process. In this process, electrical power system fault diagnosis needs three kinds of information to identify fault components: protection-breaker associations, breaker-primary component (such as line, transformer, bus and so on) associations and protection-primary component associations. Firstly, the protection setting values...
This paper developes a fault diagnosis system based on IEC61970 and IEC61850 standard series. The key problems in fault diagnosis system are the deficiency and standardization of distributed fault information. This fault diagnosis system get fault information mainly from SCADA and fault information system. The information from SCADA, including network topology and switch state, is modeled based on...
Through potassium pyrosulfate melting method, the acidity titanium dioxide sol is prepared, and then the TiO2/sepiolite composite water treatment agent is prepared by serials of soaking, shaking and heating process, the adsorption and photo-catalysis property of TiO2/sepiolite composite water treatment agent to the simulated active-blue dye wastewater is also studied. The results showed that, compared...
In this paper, the occurrence and removal of eight fluoroquinolone antibiotics were investigated at a sewage treatment plant (STP) in Shanghai, China. The most frequently detected fluoroquinolone antibiotics in the present study were norfloxacin, ciprofloxacin and lomefloxacin. The concentrations of these compounds in water samples at the STP ranged from 103 to 1786 ng L-1, 14 to 1406 ng L-1 and 21...
This paper analyzed the risk factors and the degree of risk effects of rail transit project by AHP model. From the aspect of projectpsilas overall evaluation, the study inspected the key element of risk system of rail transit projects, including market factors and operational factors. Based on risk identification, calculated the single-factor and multi-factor weight in the risk of rail transit projects.
