本报导了一种新的summing算法的核磁共振实验实现。实验中我们用到了四个量子位的核自旋体系,其中两个量子位构成输入寄存器,另两个量子位构成输出寄存器。最后的实验结果只需通过测量输出寄存器中核自旋的谱线获得。 相似文献

Artificial intelligence is one of the fastest-developing areas of science that covers a remarkably wide range of problems to be solved. It has found practical application in many areas of human activity, also in medicine. One of the directions of cooperation between computer science and medicine is to assist in diagnosing and proposing treatment methods with the use of IT tools. This study is the result of collaboration with the Children’s Memorial Health Institute in Warsaw, from where a database containing information about patients suffering from Bruton’s disease was made available. This is a rare disorder, difficult to detect in the first months of life. It is estimated that one in 70,000 to 90,000 children will develop Bruton’s disease. But even these few cases need detailed attention from doctors. Based on the data contained in the database, data mining was performed. During this process, knowledge was discovered that was presented in a way that is understandable to the user, in the form of decision trees. The best models obtained were used for the implementation of expert systems. Based on the data introduced by the user, the system conducts expertise and determines the severity of the course of the disease or the severity of the mutation. The CLIPS language was used for developing the expert system. Then, using this language, software was developed producing six expert systems. In the next step, experimental verification was performed, which confirmed the correctness of the developed systems. 相似文献

在地铁屏蔽门系统的故障诊断中,传统方法存在效率低、人工负担重等缺陷。为此,设计了基于故障树的故障诊断专家系统。先用屏蔽门的资料构建出扩展故障树,然后使用早期不交化和模块化等方法将其简化成基本故障树,求出最小割集。在故障树的基础上,设计了专家系统的知识获取和表示机制,建立了知识库。在构建推理机时,采用了双向推理、全自动推理、半自动推理、人工回溯等策略,提高了诊断效率和可信度。该系统可与综合监控系统进行接口,能对相关信息进行推理分析,对潜在故障进行预警,对已发生故障进行快速定位和诊断,出具故障报告和处理建议书,并提供故障模拟及培训功能。试用者的反馈意见表明该系统具有较好的实用价值。 相似文献
