In view of the existing regional traffic state classification method cannot completely reflect the controllable state of city road network problems, puts forward a constraint based on saturation equilibrium of multi intersection state controllability analysis model. First, the equilibrium of saturation control method to control the multi intersection; secondly, the equilibrium of saturation constraints,...
Surrogate modelling and model management are key points for evolutionary optimization of chemical processes. This paper proposes an evolutionary algorithm with the help of adaptive surrogate functions (EASF), in which approximate models' establishment and management are combined to search the optimal result. To construct an appropriate surrogate model, a new hybrid modelling framework with adaptive...
This paper studied the commercial bank China (referred to as "commercial banks") whole emergence of big data system, the unified management of risk management chain of commercial banks, established in the risk control of commercial banks under the condition of the intelligent system control model, discusses the emergence of commercial bank data system, and dynamic stability on the business...
This article researches on node importance ranking of multiplex network. Existing node importance ranking methods are amost monoplex network using only single relationship. However, in real life a person often has various relationships, so how to rank nodes of multiplex network is more realistic and meaningful. In this article, we propose a multiplex network node ranking method based on weighted aggregation...
We constructed a new secure searchable encryption scheme aided by a computationally powerful but untrusted cloud server. Our scheme allows a client to provide a single search token to the server, but still allows the server to search for that token's word over all the documents he can access that encrypted with different keys. We achieved the scheme using multikey fully homomorphic encryption (MFHE)...
At present, due to the lack of speed guidance, most of the vehicles have to wait for green time at the downstream of intersections, which increases the delay of vehicles. In order to solve this problem, this pager presents a new dynamic speed guidance model based on the Cooperative Vehicle Infrastructure System (CVIS), which can collect more real-time traffic data by vehicle to Infrastructure communication...
With the rising growth trend of data size in the Internet era, storage, analysis, and processing of big data arebecomingamong the strongtopics in academia and industry. Typical big data processing platforms adopt the MapReduce programming model to perform application processing. For example, the deployment and calculation method of Hadoop are as follows: Hadoop first collects data and stores them...
In this paper, we present a two-dimensional inversion method for triaxial induction logging data in a layered and transversely isotropic formation with invasion. With a triaxial transmitter and receiver, all nine components of the apparent resistivity tensor can be measured, making it possible to invert for the resistivity in the vertical direction. We choose the Gauss-Newton method as the inversion...
In this paper, a one-dimensional inversion method is presented to determine tilted triaxial conductivity in a dipping layered formation using triaxial induction measurements. The tilted triaxial conductivity is described by three conductivity components and three Euler angles. The inversion problem is solved with the Gauss-Newton method combined with the multiplicative regularization technique. There...
The authors conducted a meta-analysis about the relationship between Information Technology (IT) capability and business performance which aggregates empirical findings from the information technology literature. This paper confirms that IT capability has significant impact on business performance. Our research also finds that different types of IT capability measurement, different types of performance...
This paper addresses task assignment problem fortree-structure task model on heterogeneous multicore embedded systems with time constraint considering both execution time and communication load. The goal is to minimize the total system cost for a given task graph representing a set of tasks and data dependencies in a heterogeneous multicore systemwhile the time constraint is satisfied. Instead of...
Fuel elements cycling system (FECS) is the key system to realize the "multi-pass" scheme of spherical fuel elements in pebble bed reactor. The control logic of FECS is very complex, and hence a reasonable system operation planning is necessary to effectively reduce the design period of the control system. In this paper, considering the complexity of FECS and the uncertainty of the process...
With industrialization process rapidly speeding up in our country and the dramatically growing of demands about mine development, people pay more attention to reasonably explore and effectively make use of mine resource, so it is priority to research the construction of digital mine. If data warehouse technology has been applied to the present mining industry, a new perspective to the analysis of...
This paper deduces the conception of mining information model from Building Information Model. It also discusses the content and structure of mining information model, and emphasizes lifecycle management in mine construction. Furthermore, it analyzes the activities in each of phases: planning, design, construction, production and ending based-on mining information model. Finally, it illustrates that...
This paper presents a unified framework for human action classification and localization in video using structured learning of local space-time features. Each human action class is represented by a set of its own compact set of local patches. In our approach, we first use a discriminative hierarchical Bayesian classifier to select those space-time interest points that are constructive for each particular...
The normal-inverse model arises as a normal variance-mean mixture with an inverse Gaussian mixing model. The resulting model, it is very complicated to obtain the influence measures based on the tradition method. In the present paper, several diagnostic measures for outlier data mining are obtained based on the conditional expectation of the complete-data log-likelihood function based on the EM algorithm...
This paper presents a method to predict degradation path of products using time series modeling procedure based on product performance degradation data. The product performance degradation data are treated as a time series data and stochastic process are utilized to describe the degradation process for predicting long-term trend. A degradation test is processed for miniature bulbs until they failed...
The physics of failure (PoF) methodology is a primary approach for prognostics, especially for those of electronic products and assemblies. This paper summarizes the requirements for developing a generic field deployable prognostic software system using the model-based approach. It then proposes an implementation solution to design such a system while meeting those requirements. It in the end shows...
For long lifetime and high reliability products, it is difficult to obtain failure time data in a short time period. Hence, Accelerated Degradation Testing (ADT) is presented to deal with the cases that few or no failure time data could be obtained but degradation data of the primary parameter of the product are available. Step-Stress ADT (SSADT) is commonly used for the advantage that it needs only...
The purpose of this paper is to explore three-dimensional (3D) visualization methods of flow unit in oil block.
