In view of the situation that the traditional management system for the regional economy is influenced by excessively large number of entities and the huge dynamic changes of the economic structure, a kind of management system for coordination degree of regional economic development (hereinafter referred to as MSCDRED for short) based on the fusion of the spatial econometric model is put forward in this paper. the spatial econometric model is used to optimize the nonlinear characteristic indexes that have the influence on the regional economic development, so as to further obtain the initial data for the management of the regional economic development. And then the multi objective theory of decision making is applied to conduct the trade mediation on the long-term conflict of the regional economy. Finally, the experimental results are analyzed, and the following can be known from the analysis: Compared withthe other different regional economic management systems, the efficiency of management in the system designed in this paper is very high. And it can predict the regional economic development trend accurately, so as to provide a reference frame for the management of the regional economic development.

Optical network management and solution system provides services for a complete end-to-end provisioning on the transport network. In Optical networks, various technologies like SDH, PTN, EoSDH and WDM are integrated with each other and also it implemented withtheir own required network elements. this complex hierarchy and the large value of network data are in each and every individual EMS (Element Management System). While these various EMS data are collected through the north bound interface in primary Network Management and Solution System, it should be large scale data with multiple varieties of data set. Traditional data processing tools like MySQL cannot reach the requirement up to this level. this paper approaches the network big data handling with Hadoop distributed file system to overcome that incompetence. Using Hadoop advantages like automatic cluster distribution of data handling, parallel processing and open source with integration of multiple platforms, this is used for the network discovery, network alarm extraction and integrating with network application platforms. this paper discuss the performances of the traditional MySQL DBMS and Hadoop based data processing frameworks for Optical network management systems. Various sizes of optical network data in terms of links processed and results are discussed. Hadoop with Spark engine provides good efficiency compared to others for the optical network management system while it increases in size is observed.

Model extraction allows the automatic construction of behaviour models from an available implementation, which can be fed into existing analysistools. Even though these models are usually analysed using qualitative properties, many interesting and relevant properties of current systems are related to quantitative aspects, such as the probability of reaching a certain state or how many times a certain task is expected to be executed. In this work, we extend an existing model extraction approach to include probabilistic information. the original approach creates Labelled Transition systems (LTS) from Java code based on execution traces. the traces are processed by a tool that identifies contexts, which represent abstract states of the system, considering static and dynamic information, producing context traces. We use these context traces to calculate transition probabilities and generate models in the input language of a probabilistic model checker. We evaluate our approach in case studies and demonstrate that, by using context traces rather than simple traces, we produce more accurate models, thereby with probabilistic information closer to the real behaviour of programs, based on their observed traces. We also show how to build models of programs with single and multiple components.

Adaptive learning system is a highly intelligent learning resource service model. It can provide learners with personalized learning paths and learning resources, and improve learning by combining specific behavioral characteristics such as user learning habits, learning methods and knowledge capacity, make each student can have his own "exclusive teacher."this paper focuses on the three core modules of the adaptive learning system-the knowledge network model, the cognitive level model and the adaptive recommendation model. Firstly, based on Ebbinghaus memory theory, students' memory rules are explored; knowledge network model is constructed by knowledge graph to build knowledge trees; dual-subject recommendation mechanism is adopted in adaptive recommendation models to integrate users and systems. Secondly, this paper designs a knowledge network construction method suitable for describing and demonstrating the characteristics of university courses, that is, using the knowledge tree to visualize knowledge points. Finally, this paper designs a representation method that can effectively distinguish the knowledge of different students. When using clustering and lag sequential analysis to determine the cognitive level of students, the "red and green traffic lights" form is used to grasp the knowledge points. this is also an element labeling method to reflect the progress of learning more vividly. the research results show that the resulting three-core module has better performance and higher adaptability. the conclusions of this study help to establish a relatively complete adaptive learning system to promote students' self-learning.

the possibility to simulate hypothetical scenarios without harming the business using What-If analysistools and to retrieve highly refined information is an interesting way of achieving such advantages. In a previous work, it was introduced a hybrid model that combines What-If analysis and OLAP usage preferences, which helps filtering the information, meeting the users' needs and business requirements without losing data quality. In addition, it helps to overcome the lack of a user expertise using What-If analysis process. In this paper, we propose a formal verification of a hybridization model, integrating What-If analysis scenarios with OLAP usage preferences, which aim to suggest to the user enriched What-If scenarios based on the usage preferences of a specific user. For this, we used Alloy to specify and verify the referred model, which enables to analyze and verify our hybrid model, discovering possible ambiguity and inconsistencies.

the generations of the past decades are addicted to the information and the internet. the ICT devices determine their everyday lives. Several studies suggest that such tools are needed to teach these generations effectively, to make the learning process easier and quicker. the corresponding facts must be chosen, filtered and utilized from a constantly growing set of information by the students. they had to think and then Figure out the answer from these information. the ability of algorithmic thinking, the development of analytical thinking, and the promotion of thinking in the system play a key role. the involvement of 3D virtual spaces in education is investigated by more and more studies nowadays. In this article, through an example of a search task, an eye-tracking system is used to find out how much a 3D virtual space is more effective than a conventional LMS system.

this article presents CREST, a novel domain-specific language for the modelling of cyber-physical systems. CREST is designed for the simple and clear modelling, simulation and verification of small-scale systems such as home and office automation, smart gardening systems and similar. the language is designed to model the flow of resources throughout the system. It features synchronous system evolution and reactive behaviour. CREST's formal semantics allow real-valued time advances and the modelling of timed system evolution. the continuous time concept permits the precise simulation of future system behaviour by automatically calculating next transition times. We present CREST in a practical manner, and elaborate on the Python-based DSL implementation and simulator.
