πScope: Python based scientific workbench with MDSplus data visualization tool

FUSION ENGINEERING AND DESIGN 2016年 112卷 835-838页

作者： Shiraiwa, S. Fredian, T. Hillairet, J. Stillerman, J. MIT Plasma Sci Fus Ctr 77 Massachusetts Ave Cambridge MA 02139 USA USACEA IRFM F-13108 St Paul Les Durance France

A newly developed python based scientific data analysis and visualization tool, pi Scope (http://***), is reported. The primary motivation is 1) to provide an updated tool to browse the MDSplus data beyond existing dwscope/jScope and 2) to realize a universal foundation to construct interface tools to perform computer modeling from experimental data. To visualize MDSplus data, pi Scope has many features including overplotting different signals and discharges, generating various plot types (line, contour, image, etc.), performing in-panel data analysis using python scripts, and producing publication quality graphics. The logic to generate multi-panel plots is designed to be backward compatible with dwscope, enabling smooth migration for users. pi Scope uses multi-threading in data loading, and is easy to modify and expand due to its object-oriented design. Furthermore, A user can access the data structure both from a GUI and a script, enabling relatively complex data analysis workflow built quickly on pi Scope. (C) 2016 Elsevier B.V.

DNA Sequence Comparisons Using Codons

引用

ARABIAN JOURNAL FOR SCIENCE AND ENGINEERING 2014年第3期39卷 1889-1896页

作者： Thabit, Khalid Al-Ghuribi, Sumaia M. Al-Aswadi, Fatima N. King Abdulaziz Univ Fac Comp & Informat Technol Jeddah 21413 Saudi Arabia

One of the significant steps in the analysis of phylogenetic relationships between species is the DNA sequence comparison. In this paper, a fast method for comparing DNA sequences was introduced based on the frequencies of the codons it contains. The frequencies of codons are calculated in a way where the similarity of DNA sequences can be avoided. The method is tested for 15 species in both short and long DNA sequence. A software was implemented using wxpython that uses this method and tests it. The results were compared manually with the data in NCBI, and it was found that our method works well, thus proving its benefit. Finally, to make this method available for specialists, a software is uploaded using this method to cloud depends on cloud computing platform, "Google App Engine".

In today's world large number of companies are facing problem related to version control systems. The problem is about comparing binary files such as excel file and recalling what changes have been done over the period of time. It is hard to keep track of what all changes have been made over a set of files in the company and hence comes the need of an approach which can fetch and compare the files with changes that have been done. Since binary files are not readable with human eye, this approach can convert those binary files to XML and compare it on the GUI to show and highlight the changes that have been made over the version control system. A VCS is a system that keeps track of changes one does over a set of files over the time and records it so it can be recalled in the future when needed. Binary file conversion approach is implemented to provide a solution to the problem for the companies that have extensive use for the binary files like Excel and need to refer the changes that were made on them.

Configuration tool prototype for the Trusted Computing Exemplar project

Configuration tool prototype for the Trusted Computing Exemp...

作者： Terrence M. Welliver Naval Postgraduate School

学位级别：硕士

The creation of a configuration vector file used to initialize the Least Privilege Separation Kernel (LPSK) of the Trusted Computing Exemplar (TCX) project to an initial secure state is currently a manual process that is tedious and error prone. A software application that removes many of the complexities of creating a valid configuration vector file is needed. This thesis describes the first steps taken to design and implement a graphical user interface (GUI) configuration vector tool that enables a user to easily create valid configuration vector files (both human-readable and binary). The tool allows a user to focus on the meaning of the configuration vector rather than on the syntactic details of the file. A prototype of the configuration vector tool was successfully designed, implemented, and tested in this thesis. The prototype provides the first functional GUI software application that creates configuration vector files. The logical design of the toll will permit further extensions to be readily incorporated.

随着农业信息化进程的快速推进,“精细农业”已经广泛应用在农业生产当中,而低空遥感技术作为“精细农业”的核心技术之一理所当然地成为了科研工作中的“尖兵利器”。区别于传统的农作物信息获取方法,高光谱技术以其高分辨率、高灵敏度、大信息量、测量方便准确等特点,在农作物信息的野外采集中颇受青睐。丰富完整且系统化的高光谱数据也为实现遥感技术的从定性化到定量化提供了数据支持。但是,高光谱数据结构复杂严谨、信息量大,野外采集的光谱数据离开了环境信息、理化信息等配套辅助信息后,并不能独立应用。对于农作物的低空遥感科研工作来说,迫切需要设计一个针对光谱信息,并结合辅助信息的数据管理系统。XML即可扩展标记语言,是用来描述元数据的语言。元数据是关于数据的数据,它既是一种数据应用标准,也是一种编码体系,在数据共享的分布式环境中对数字化的信息进行结构和依赖关系的描述。在诸如网络资源、文献资料、社会科学数据集和地理空间信息等领域,都形成了相关的国际元数据标准,来指导数据的内容和结构,但是在光谱信息元数据方面的相关研究并不多见。本文以此为契机,通过对光谱数据库和元数据模型系统的发展状况进行深入研究,为实验中产生的大量光谱数据设计了通用的光谱信息元数据模型标准,并以此为基础构建了光谱信息管理系统,并对相关关键技术进行了研究与探讨。本文的研究工作主要在于以下几个方面:(1)根据在实验中采集到的时序性的光谱数据、环境数据和其他辅助数据设计了光谱信息元数据模型,来对光谱测量中涉及的各类信息进行结构化、规整化处理。(2)采用基于wxWidgets技术的wx Python设计了针对光谱信息管理系统的客户端界面,来对光谱信息进行可视化操作。(3)运用MVC框架设计了光谱信息管理系统的核心程序,并将元数据模型融合到系统中来,实现了基于XML数据文档的信息管理。
