c2 auditing in the x Display Manager
Annual Computer Security Applications Conference, 1993Co-Authors: J DemeesterAbstract:This paper describes the implementation of C2 auditing in the MIT X Consortium X Display Manager (XDM) on a Sun Workstation. This custom implementation of XDM audits user logins, attempted logins and logouts by creating a C2 audit trail in the workstation's audit file. Additionally, when a user has exceeded a specified number of failed login attempts, the user's account and/or workstation may be disabled. >

USE OF OBJECT ORIENTED INTERPRETIVE LANGUAGES IN AN ACCELERATOR CONTROL SYSTEM
2014Co-Authors: N. Yamamoto, A. Akiyama, S. Araki, T. Katoh, T. Kawamoto, I. Komada, K. Kudo, T. Naito, T T NakamuraAbstract:In a control system for a high energy accelerator, like KEKB, quick application development/modification is re-quired. This short turn-around time is especially important during a commissioning of the accelerator. In KEKB con-trol system, we have achieved this goal by introducing in-terpretive programming languages, Python and SAD, in the control system. SAD is the language originally developed at KEK for accelerator lattice design. The other, Python, is the language system distributed as a public domain soft-ware. These languages are used not only for prototyping ap-plication but also for developing application software used in daily operation. These languages are easier to learn and safer to use compared to compiled languages such as C or C++. Interface to the appropriate widget library from these interpretive languages, such as Tk/gtk+ widget greatly re-duces effort needed for developing graphical user inter-faces. Modular and object oriented features in the languages al-low incremental development of application software. This method benefits reliability and maintainability of the soft-ware. Authors will discuss productivity, performance and maintainability of the system based on experiences in the KEKB control system. 1 KEKB CONTROL SYSTEM KEKB[1] is an asymmetric electron-positron collider for B-meson physics built in KEK, Japan. It started its opera-tion on December 1st, 1998 after 5 years of construction. The control system for KEKB accelerators[2] were built using EPICS Toolkit[7] as a framework of the control sys-tem. The core of EPICS toolkit is a runtime database run-ning on VME single-board computers and a network protocol, called channel access, to exchange data be-tween computers. On the top of channel access, EPICS provides various tools to construct a control system. The tools include DM/EDD (Display Manager/Displa

fully embedded epics based control of low level rf system for superkekb
2010Co-Authors: K Akai, K Furukawa, Shinichiro Michizono, T Miura, T T NakamuraAbstract:Towards the SuperKEKB accelerator project, a new Low Level RF (LLRF) control subsystem has been designed and under implementation to upgrade existing one, which is based on Experimental Physics and Industrial Control System (EPICS). The new control subsystem comprises a micro-TCA, a PLC and an industrial PC. Each card plugged into the MicroTCA chassis as well as the PLC’s CPU function as an embedded Input / Output Controller (IOC) of EPICS by running the IOC core program on the Linux Operating System. The industrial PC is assumed to run Extensible Display Manager (EDM) on Linux to serve as an Operator Interface (OPI) for both local and remote control. This paper describes the details of the design and the implementation under progress of the fully embedded EPICS-based low level RF control subsystem for the SuperKEKB accelerator.

six cool things you can do in Display Manager
2008Co-Authors: Jenine MilumAbstract:Many people use Display Manager but don’t realize how much work it can actually do for you. Display Manager can help you research data issues, write code for you, transform data to and from SAS, and even some things you probably shouldn’t use. Learn a few tips to make your Display Manager experience more productive.

Development of Integrated Navigation Console (INC) designed for Radiation Oncology EMR/CPOE, RIS and PACS in conformity to IHE-Japan Radiation Oncology Study group Workflow
2019Co-Authors: Ando Yutaka, Tanaka Masato, Kitora Nibuhide, Tsukamoto Nobuhiro, Kawaguchi Osamu, Emoto YutakaAbstract:PURPOSEIn Japan, EMR systems become popular in the large- and middle-scaled hospitals. The workflow in the Radiation Oncology section was not studied sufficiently. This is a barrier when we implement an EMR. This situation was pointed out in the other department for example ophthalmology and dentistry departments. It is hard to customize an EMR/CPOE according to each workflow because of a huge resource and cost.The aim of this paper is to define the user-interface framework that leads us to easy customization and suitable Display/ordering of examinations. This framework is expected to contribute to the medical safety.\nMETHOD AND MATERIALSWe defined actors to generate a user interface that enables to place orders. These actors gather necessary information from multiple systems (EMR, CPOE, PACS and RIS) and Display to a physician. Next, radiation oncologist issues orders (laboratory examinations, radiology examinations and radiation therapy prescriptions). In ordinaryEMR/CPOEs, this process needs several cascaded screen changes. But our framework provides the highly integrated console that enable to refer results and issue orders simultaneously. In the compliant to the IHE-Japan RO workflow, we defined the 4 phases of radiation oncology workflow. At first, we analyzed the function of the beginning of the radiation. We expand the concept of the CCOW (Clinical Context Object Workgroup) used in the EUA (Enterprise User Authentication) and PSA (Patient Synchronized Application) of the IHE ITI.\nRESULTSAfter our analysis, we propose five kinds of actors; (1) Display Manager, (2) Result Tracker, (3) Order Composer, (4) Order Placer, (5) Database Updater. By using these actors, we can improve the function of EMR/CPOEs. We are easily able to reform information systems and get the safety.\nCONCLUSIONWe developed prototype of the integrated navigation console and evaluated the functions. Our method that we proposed is a powerful tool that realizes patient oriented EMR/CPOSs. By using our method, physicians are able to develop own information systems according to their clinical workflows.RSNA\u2707 93th Scientific Assembly and Annual Meetin

channel access clients on the microsoft windows platform
2007Co-Authors: B G MartlewAbstract:The control system for the Energy Recovery Linac Prototype (ERLP) under construction at Daresbury uses the Experimental Physics and Industrial Control System (EPICS) and vxWorks on VME64x [1]. The client software in use during the commissioning of the accelerator is based on PC consoles running Red Hat Linux 9. Synoptic Displays and engineering panels are created using the Extensible Display Manager (EDM) and other standard EPICS extension software is used for archival, alarm handling etc. The Synchrotron Radiation Source (SRS) control system uses a bespoke control system with client software on PC consoles running Microsoft Windows. We would like to employ a similar approach for the operational client software on ERLP with Channel Access (CA) clients running on Microsoft Windows PC consoles. However, the Microsoft Visual Studio development tools and ActiveX/COM technologies used for creating client side software on the SRS control system are now outdated and have been superseded by the .NET framework and associated developer tools. This paper discusses the different options currently available for developing CA clients on the Microsoft Windows platform, along with progress in creating CA clients for the .NET framework.
