SAS是一套大型集成应用软件系统,具有完备的数据存取、数据管理.数据分析和数据展现功能.由于SAS是从大型机上的系统发展而来,针对专业用户进行设计,因此其操作至今仍以编程为主,人机对话界面不太友好,在编程操作时需要用户对所使用的统计方法有较清楚的了解,非统计专业人员掌握起来比较困难.为解决这些问题,提出了一种利用SAS的IOM编程接口,通过.NET来设置界面,读取SAS的数据源,并调用SAS的命令来分析数据,获取SAS分析结果的编程模型.  相似文献

针对陆上车辆导航定位设计了一种基于单轴光纤陀螺的简化惯导系统(Reduced Inertial Sensor System,RISS),该系统由一个单轴光纤陀螺、三个加速度计和一个倾角传感器组成。为获得较高精度的航向信息利用双天线GPS和RISS进行组合,构成双天线GPS/RISS组合导航系统,应用卡尔曼滤波技术实现数据融合,并进行仿真实验和跑车试验验证所设计系统的合理性。仿真实验结果证明双天线GPS/RISS组合导航系统与GPS/RISS组合导航系统相比,航向精度得到显著提升。跑车实验结果表明,设计双天线GPS/RISS组合导航系统的位置误差小于2m,航向角误差小于1°,能满足车载导航定位定向需求。  相似文献

The application of data-management systems in economic geology is becoming increasingly user oriented and machine independent. Many mineral-deposit computer systems remain data dependent or fixed formatted but an efficient data system with a proper data-manipulation language needs specific data structures, free format, and a prospective package of generalized modules for the user. Data management primarily requires clear formulation by geoscientist in cooperation with system analyst to serve many activities including problem solving, data content, and decision-making.File-management systems in economic geology involve: file definitions, data validation, data loading, and updating and retrieval. Structuring of a data file seems to be a clue to a successful and long-term file-management system in applied geosciences. Many commercially available file-management systems should be applied in economic geology because the functions which modern computers can perform in assisting file-management development do not essentially differ from those of other data-processing undertakings. The only specific problem in the geosciences is location and graphic form of most geoscience data presented as point, lineal, areal, spatial (three dimensional) input/output information.Data-base management systems provide interconnection between files themselves as well as between different items for different files. Few typical file-management or data-base management systems for geoscience and resources data will be compared in the table form. The paper concludes the problem of choosing and developing an effective data-base management system for its application in economic geology.  相似文献

We present an experimental comparison between two approaches to optimization of the rules for a fuzzy controller. More specifically, the problem is autonomous acquisition of an “investigative” obstacle avoidance competency for a mobile robot. We report on results from investigating two alternative approaches to the use of a Learning Classifier System (LCS) to optimize the fuzzy rule base. One approach operates at the level of whole rule bases, the “Pittsburgh” LCS. The other approach operates at the level of individual rules, the “Michigan” LCS. In this work, both of these Fuzzy Classifier Systems were designed to operate only on the rules of fuzzy controllers, with predefined fuzzy membership functions. There are two main results from this work. First, both approaches were capable of producing fuzzy controllers with subtle interactions between rules leading to competencies exceeding that of the hand‐coded fuzzy controller presented in this article. Second, the Michigan approach suffered more seriously than the Pittsburgh approach from the well‐known LCS “cooperation/competition” problem, which is accentuated here by the structural combination of Evolutionary Computation and a fuzzy system. This problem was alleviated a little by the combination of a clustered subpopulation niche system and a fitness‐sharing scheme applied to the Michigan approach, but still remains. © 2007 Wiley Periodicals, Inc.

A Wireless Sensor Network (WSN) consists of many low-cost, small devices. Usually, as they are deployed to an open and unprotected region, they are vulnerable to various types of attacks. In this research, a mechanism of Intrusion Detection System (IDS) created in a Cluster-based Wireless Sensor Network (CWSN) is proposed. The proposed IDS is an Integrated Intrusion Detection System (IIDS). It can provide the system to resist intrusions, and process in real-time by analyzing the attacks. The IIDS includes three individual IDSs: Intelligent Hybrid Intrusion Detection System (IHIDS), Hybrid Intrusion Detection System (HIDS) and misuse Intrusion Detection System. These are designed for the sink, cluster head and sensor node according to different capabilities and the probabilities of attacks these suffer from. The proposed IIDS consists of an anomaly and a misuse detection module. The goal is to raise the detection rate and lower the false positive rate through misuse detection and anomaly detection. Finally, a decision-making module is used to integrate the detected results and report the types of attacks.  相似文献

A “machine” is proposed which works with a geologist (or other scientist) to help him in his everyday work. The machine consists of a relational data base, highly structured processing software designed to reflect geological thinking and input/output interface software to aid a user of the system. The G-EXEC System represents a partial implementation of such a “geological computer”.  相似文献

Since agriculture is the major water consumer, web services have been developed to provide the farmers with considerate irrigation suggestions. This study improves an existing irrigation web service, based on the IRRINET model, by describing a protocol for the field implementation of a fully automated irrigation system. We demonstrate a Fuzzy Decision Support System to improve the irrigation, given the information on the crop and site characteristics. It combines a predictive model of soil moisture and an inference system computing the most appropriate irrigation action to keep this above a prescribed “safe” level. Three crops were used for testing the system: corn, kiwi, and potato. This Fuzzy Decision Support System (FDSS) favourably compared with an existing agricultural model and data-base (IRRINET). The sensitivity of the FDSS was tested with random rainfall and also in this extended case the water saving was confirmed.  相似文献

In Nagoya University Hospital, a Radiology Intelligent Information System (RIIS) is under construction which will be linked with the Hospital Intelligent Information System (HIIS). RIIS is composed of the radiation oncology information system and the diagnostic radiology information system which is named Imaging Diagnosis Intelligent Information System (IDIIS). IDIIS consists of three parts: (a) the Imaging Diagnosis Management System (IDMS); (b) the Picture Archiving and Communication System (PACS); (c) the Report Generation Support System for Imaging Diagnosis (RGSS-ID). Artificial intelligence methodology is applied to RGSS-ID and IDMS which includes the ordering and scheduling system of diagnostic imaging. IDIIS has an important role to improve the quality of patient care and medical education as well as image management and is an essential component for the implementation of HIIS.  相似文献

The project management-at-a-glance concept was developed to provide a communication graphic which could visibly provide the managers of several departments with an overview of all active projects. All the major milestones are predefined for simplicity. The detail between the milestones was also eliminated for clarity. The chart was designed to show multiple projects in a compressed format. Eight projects and 12 milestones can be shown on each page of the chart.

The Base SAS® package was utilized as the programming tool. The SAS/FSEDIT® product was used for data entry. The data for the report was stored in an IBM TSO sequential flat file. SAS/GRAPH's® annotate tools are used to create the layered project management chart. The SAS system was chosen because of its strong ability to handle dates and custom generated graphics.  相似文献
