Flight elements: Fault detection and fault management

Fault management for an intelligent computational system must be developed using a top down integrated engineering approach. An approach proposed includes integrating the overall environment involving sensors and their associated data; design knowledge capture; operations; fault detection, identification, and reconfiguration; testability; causal models including digraph matrix analysis; and overall performance impacts on the hardware and software architecture. Implementation of the concept to achieve a real time intelligent fault detection and management system will be accomplished via the implementation of several objectives, which are: Development of fault tolerant/FDIR requirement and specification from a systems level which will carry through from conceptual design through implementation and mission operations; Implementation of monitoring, diagnosis, and reconfiguration at all system levels providing fault isolation and system integration; Optimize system operations to manage degraded system performance through system integration; and Lower development and operations costs through the implementation of an intelligent real time fault detection and fault management system and an information management system

Expert system decision support for low-cost launch vehicle operations

Progress in assessing the feasibility, benefits, and risks associated with AI expert systems applied to low cost expendable launch vehicle systems is described. Part one identified potential application areas in vehicle operations and on-board functions, assessed measures of cost benefit, and identified key technologies to aid in the implementation of decision support systems in this environment. Part two of the program began the development of prototypes to demonstrate real-time vehicle checkout with controller and diagnostic/analysis intelligent systems and to gather true measures of cost savings vs. conventional software, verification and validation requirements, and maintainability improvement. The main objective of the expert advanced development projects was to provide a robust intelligent system for control/analysis that must be performed within a specified real-time window in order to meet the demands of the given application. The efforts to develop the two prototypes are described. Prime emphasis was on a controller expert system to show real-time performance in a cryogenic propellant loading application and safety validation implementation of this system experimentally, using commercial-off-the-shelf software tools and object oriented programming techniques. This smart ground support equipment prototype is based in C with imbedded expert system rules written in the CLIPS protocol. The relational database, ORACLE, provides non-real-time data support. The second demonstration develops the vehicle/ground intelligent automation concept, from phase one, to show cooperation between multiple expert systems. This automated test conductor (ATC) prototype utilizes a knowledge-bus approach for intelligent information processing by use of virtual sensors and blackboards to solve complex problems. It incorporates distributed processing of real-time data and object-oriented techniques for command, configuration control, and auto-code generation

Attendance and employee leave are important factors for an agency or company to achieve goals, this is related to discipline and has an impact on the performance of each employee. Therefore, it is necessary to have special data collection to record employee leave, employee overtime and attendance and absence so that work activities can be recorded in real time and properly. There are many ways that can be done to achieve a good attendance information system, one of which is using personal computer technology where its application is website-based attendance software. At the office of PT. Pinus Merah Abadi system used in the attendance process is still manual using daily attendance papers, leave and overtime which have an impact on the efficiency and effectiveness of data collection, data search as well as data recap calculations which take a relatively long time. Meanwhile, the risk of errors and loss of attendance data is getting bigger. Based on the above problems, an information system for attendance, leave and employee overtime was made at the PT. Pinus Merah Abadi. The research method is the method used in data collection which includes: research methods, interviews and literature. While software development using waterfall which includes: needs analysis, design, coding, testing and implementation. With the production of employee leave applications, employee overtime and employee attendance based on the website, it can provide convenience in the process of employee leave, employee overtime and attendance, data search and recapitulation of employee leave, employee overtime and attendance, as well as minimizing losses and errors in recording employee leave data, overtime employees and attendance at the office of PT. Pinus Merah Abadi.Absensi kehadiran serta cuti pegawai merupakan faktor penting untuk sebuah instansi atau perusahaan untuk mencapai tujuan, hal ini berkaitan pada kedisiplinan dan berdampak pada kinerja dari masing-masing pegawai. Oleh karena itu, perlu adanya pendataan khusus untuk mencatat cuti pegawai, lembur pegawai dan absensi kehadiran dan ketidakhadiran agar aktifitas kerja dapat tercatat secara real-time dan baik. Banyak cara yang bisa dilakukan buat mencapai sistem informasi absensi yang baik, salah satunya memakai teknologi personal komputer dimana penerapannya dengan software absensi berbasis website.

Research Tool Patents and Free-Libre Biotechnology: A Unified Perspective.

This paper proposes a unified conceptual framework to analyse the multiple role and consequences of patents in the case of biotechnology research tools. We argue that the knowledge/information and independent/complementary nature of research tools define heterogeneous frameworks in which the patent system plays different roles. In particular, using the analogy with the free-libre open source movement in software, we show that patents can promote open innovation by ensuring the freedom of some pieces of knowledge. A strong conclusion of the paper is therefore that, against common belief, an adequate use of the patent system may contribute to preserving freedom of access to upstream research tools within a framework that we call free-libre biotechnology.Intellectual property rights, sequential innovation, open source, life science, collective invention.

Intelligent IoT and Dynamic Network Semantic Maps for more Trustworthy Systems

As technology evolves, the Internet of Things (IoT) concept is gaining importance for constituting a foundation to reach optimum connectivity between people and things. For this to happen and to allow easier integration of sensors and other devices in these technologic environments (or networks), the configuration is a key process, promoting interoperability between heterogeneous devices and providing strategies and processes to enhance the network capabilities. The optimization of this important process of creating a truly dynamic network must be based on models that provide a standardization of communication patterns, protocols and technologies between the sensors. Despite standing as a major tendency today, many obstacles still arise when implementing an intelligent dynamic network. Existing models are not as widely adopted as expected and semantics are often not properly represented, hence resulting in complex and unsuitable configuration time. Thus, this work aims to understand the ideal models and ontologies to achieve proper architectures and semantic maps, which allow management and redundancy based on the information of the whole network, without compromising performance, and to develop a competent configuration of sensors to integrate in a contemporary industrial typical dynamic network

What international monetary system for a fast-changing world economy

Though the renminbi is not yet convertible, the international monetary regime has already started to move towards a 'multipolar' system, with the dollar, the euro and the renminbi as its key likely pillars. This shift corresponds to the long-term evolution of the balance of economic weight in the world economy. Such an evolution may mitigate some of the flaws of the present (non-) system, such as the rigidity of key exchange rates, the asymmetry of balance of-payments adjustments or what remains of the Triffin dilemma. However it may exacerbate other problems, such as short-run exchange rate volatility or the scope for â??currency warsâ??, while leaving key questions unresolved, such as the response to capital flows global liquidity provision. Hence, in itself, a multipolar regime can be both the best and the worst of all regimes.Which of these alternatives will materialise depends on the degree of cooperation within a multilateral framework.
