In this paper, we analyze six protein interaction networks widely used for protein complex detection, and compare the performance of six classic computational methods on them in order to find the relations between network characteristics and the performances of these complex detection methods. Furthermore, we explore the difference among the two complexes detected by different methods and the real...
Train positioning is a fundamental function which is required by many location-based railway applications. The rapid development of satellite navigation technology enables a better cost-effectiveness for the safety-critical railway train control systems. When using BDS (BeiDou Navigation Satellite System) in train control, it has to be ensured the positioning module takes full consideration of the...
Cooperative Vehicle Infrastructure System is an important research area of ITS. Evaluation of CVIS aims to evaluate the technical feasibility, economic benefit and the social effects of CVIS. This paper puts forward a comprehensive evaluation method based on Analytic Hierarchy Process (AHP) and Grey Relational Analysis Process (GRAP). It selects parameters which can reflect the performance of traffic...
Microblogs are popular online services on Internet. Many popular microblogging services have been empirically investigated. This paper attempts to seek unique characteristics of a peculiar microblogging service: Yiban Microblog. It is limited to college students and staffs with inherent verified accounts. We conduct an almost exhaustive measurement on the Yiban microblogging service. Unexpectedly,...
Recent years have witnessed a rapid growth in using Web services for data publishing and sharing among organizations. To improve the efficiency of software development and economize on human and material resources, service reuse is viewed as a powerful means which will not only reuse atomic services, but also reuse arbitrary granularities of Service Process Fragments (SPFs). However, effectively reusing...
Autonomous detecting and tracking of mobile ground robots are two fundamental tasks for the cooperation between quadrotor UAVs and UGVs. In our work, a T-shape landmark is installed on the top of a ground robot so that the quadrotor can use onboard monocular camera to perform fast object detection. Considering the effects of shading, shadows and varying lighting condition, the adaptive thresholding...
To improve comprehensive performance of denoising range images, an impulsive noise (IN) denoising method with variable windows is proposed in this paper. Founded on several discriminant criteria, the principles of dropout IN detection and outlier IN detection are provided. Subsequently, a nearest non-IN neighbors searching process and an Index Distance Weighted Mean filter is combined for IN denoising...
We present a proof of concept demonstration of THz free-space communication employing orbital angular momentum (OAM) multiplexing. Two different OAM modes are multiplexed and de-multiplexed in experiment via 3D printed spiral phase plates.
We design and fabricate on-chip two/three mode (de)multiplexer using a tapered asymmetrical directional coupler. System experiments of OFDM 64/128/256-QAM data transmission have been carried out for on-chip two/three mode (de)multiplexing applications.
We experimentally demonstrate power-controllable multicasting of OFDM 64-QAM signal from single Gaussian mode to multiple OAM modes using a single phase-only spatial light modulator assisted by a feedback control. The precision of power control is less than 1 dB.
As a popular type of parallel evolutionary algorithms, distributed evolutionary algorithms (DEAs) are widely used in a variety of fields. To get better solutions of concrete problems, a scheme of subpopulation diversity based accepting immigrant in DEAs is proposed in this paper. In migration with this scheme, an immigrant will be put into its target subpopulation only if its current diversity is...
As an important resource and productive element, big data permeates all the domains, such as: E-commerce, traffic management or smart city. When possessing the capability of aggregating the information and then mining and analyzing deeply the latent knowledge, it will bring endless innovative achievements. Therefore, big data mining and deep analytics is becoming one of the research hotspots, and...
The single-ingredient pellet formulas of traditional Chinese medicines have been accepted by the patients and have great market in hospitals recently. As information-based equipment for deploying single-ingredient pellet formulas of traditional Chinese medicines, the automatic deploying system is in great demand in hospitals. An automatic deploying system for single-ingredient pellet formulas of traditional...
The key to image interpolation is recovering pristine edge and detailed information as much as possible. Robust soft-decision adaptive interpolation (RSAI) shows excellent interpolation performance by adding weighted least squares estimation to soft-decision adaptive interpolation (SAI).We put forward a novel interpolation strategy-double constraints to modify and improve RSAI. Every pixel is double...
Train operation energy consumption occupies a large proportion of whole rail transport resource consumption. Aiming at improving energy utilization, current research is mainly about saving energy while security and time are limiting conditions. However, actual train operation is a complex process which has strict requirements on safety, energy consumption, precise parking and some other factors. This...
We report a complete experimental realization of measurement device independent quantum key distribution system with decoy method, which closes loopholes in both source and detection. 25-kbit secure key is generated over a 50-km fiber link.
With the wide application of data mining, many data mining applications need to use past and current data to predict the future state of the data. In view of this situation, we propose a new method, namely AMFP-Stream, for predicting frequent patterns over data streams efficiently and effectively. AMFP-Stream algorithm can predict those frequent item sets that have high potential to become frequent...
Cognitive network is a new approach to solve self-management of complex heterogeneous network, and its model and analysis method are key problems to be solved. a formal modeling and analysis method for cognitive network is proposed based on stochastic process algebra. Firstly, basic concept of PEPA is introduced. then system behaviors are abstracted combining with cognitive essence, and formal models...
The conventional theory of sampling inspection is not suitable for the quality inspection of ocean data due to its specific characters such as magnanimity, multi-source, multi-dimensions, various types, and obvious spatiality. Thus, in this paper, we proposed a novel multi-scale fuzzy sampling model based on fuzzy mathematics. Given their magnanimity, multi-dimensions, and various types, the ocean...
Centered around the model of ESDDM, a software evolution process model based on evolution behavior interface, and the knowledge of component classification and component retrieval evaluation, this paper furthered previous work by proposing a component reusability evaluation method based on fuzzy mathematics. The method provides an effective way of evaluating the reusable ability of a certain component...
