Development and evaluation of a fault-tolerant multiprocessor (FTMP) computer. Volume 4: FTMP executive summary

The FTMP architecture is a high reliability computer concept modeled after a homogeneous multiprocessor architecture. Elements of the FTMP are operated in tight synchronism with one another and hardware fault-detection and fault-masking is provided which is transparent to the software. Operating system design and user software design is thus greatly simplified. Performance of the FTMP is also comparable to that of a simplex equivalent due to the efficiency of fault handling hardware. The FTMP project constructed an engineering module of the FTMP, programmed the machine and extensively tested the architecture through fault injection and other stress testing. This testing confirmed the soundness of the FTMP concepts

Development and evaluation of a Fault-Tolerant Multiprocessor (FTMP) computer. Volume 2: FTMP software

The software developed for the Fault-Tolerant Multiprocessor (FTMP) is described. The FTMP executive is a timer-interrupt driven dispatcher that schedules iterative tasks which run at 3.125, 12.5, and 25 Hz. Major tasks which run under the executive include system configuration control, flight control, and display. The flight control task includes autopilot and autoland functions for a jet transport aircraft. System Displays include status displays of all hardware elements (processors, memories, I/O ports, buses), failure log displays showing transient and hard faults, and an autopilot display. All software is in a higher order language (AED, an ALGOL derivative). The executive is a fully distributed general purpose executive which automatically balances the load among available processor triads. Provisions for graceful performance degradation under processing overload are an integral part of the scheduling algorithms

Development and evaluation of a fault-tolerant multiprocessor (FTMP) computer. Volume 1: FTMP principles of operation

The basic organization of the fault tolerant multiprocessor, (FTMP) is that of a general purpose homogeneous multiprocessor. Three processors operate on a shared system (memory and I/O) bus. Replication and tight synchronization of all elements and hardware voting is employed to detect and correct any single fault. Reconfiguration is then employed to repair a fault. Multiple faults may be tolerated as a sequence of single faults with repair between fault occurrences

Dilema dalam Transformasi Desa ke Nagari : Studi Kasus di Kenagarian IV Koto Palembayan, Provinsi Sumatera Barat

The implementation of local autonomy regime gives an interesting socio-political explanation of how is the local genuine governance system, the so-called nagari, to operate in West Sumatera. Based on Law No. 22/1999 as amended by Law No. 32/2004, the Regional Government of West Sumatera introduced Regional Law No. 9/2000 as legal foundation to regulate the implementation of nagari in the region. The study, was conducted in Nagari IV Koto Palembayan, District of Agam, Province of West Sumatera. It was intended to 1) describe and analyze the implication of structural change from nagari to desa and its return to nagari system, 2) analyze potential conflicts that occur in the transformation from desa to nagari. The study used qualitative approach, in which data and information were mostly collected by in-depth interviews supported by observation, study of literature and documents. It was found that 1) such intervention brought about widely social change at local level, 2) the transformation from desa to nagari stimulated some potential conflicts at local level. It is realized that it is uneasy for the government to synergize modern and traditional institution of governance in a single system. In case, the control of such a complicated system is very poor, then the implementation of nagari system is substantially hindered

Economic Performance of Ohio’s 88 Counties

Author Institution: Janson Industries, Canton, OH; Dept of Theoretical and Applied Mathematics; Dept of Statistics, University of AkronThe value added by the work force varies greatly among Ohio’s 88 counties. In the aggregate, the value added equals the gross domestic products (GDP) of the county. With an adjustment for depreciation, the value added by the county production system is equivalent to the aggregated real income (Y) of the county, the best measure of county economic performance. Measuring GDP or Y by aggregating all production of a region is a labor-intensive procedure. The purpose of this paper was to see if data on investment in real capital resources within the county and investment in human resources within the county (education) could be used to estimate domestic income without requiring a production census. Aggregated county income in Ohio was predicted reliably using county-specific data on the current value of taxable real property (investment in non-human resources), and the estimated value of the investment in educational attainment by the non-degreed work force of the county (human resources). A data vector for investment in the degreed work force was also used in the analysis. All vectors include values for the exhaustive set of Ohio’s 88 counties. A total of 9 regressions were computed using various combinations of the data. Using established statistical criteria the regression equation that uses investment in real capital and investment in the non-degreed work force was selected as the best method. These criteria included an R-square in excess of 0.99 and a mean square error that was smallest among the alternative regressions

(Conflict Resolution of Irrigation Development: Case Study in Ibu Subdistrict of West Halmahera District)

The objective of this research is to understand the conflict resolution of dam and irrigation development in three subdistrict villages of Ibu Halmahera Barat district 2013. This research uses analysis of dispute style (AGATA) in the form of: avoidance, accommodating, compromise, competitive, and collaboration. The results showed that there are two styles of conflict that is avoid and competitive style. Both style of disputes are transformed into a compromise style after the opposing party offers negotiation of land compensation. Based on this it can reduce the two parties, so that the mediator easily deal with the conflict. The settlement path is through mediation and facilitation by bringing the two conflicting parties together with the mediator of West Halmahera people's parliament. The decision taken is to stop the construction of dam and irrigation channels under construction. The decision, in addition to reducing the escalation of tensions, also to anticipates violet conflict between the two parties (the pros and cons of development)

ABSTRACT - Introduction: Percutaneous coronary intervention (PCI) is the gold standard for patients with ST elevation acute myocardial infarction (STEMI). It is important to evaluate the influence of this treatment in the prognosis of patients through the identification of highrisk groups for adverse events. Objectives: To evaluate the influence of PCI on the prognosis of patients with STEMI. Identify predictive factors of mortality and death or reinfarction, or revascularization or stroke (MACCE). Identify high-risk groups for these endpoints. Methodology: This study included 338 STEMI patients (62±13 years-old; 73% males), who underwent PCI, from 01/01/2008 to 31/12/2009. We assessed the demographic and clinical data, procedure, in-hospital outcome and clinical follow-up (25 ± 13 months). Results: We identified as predictors of mortality: age, peripheral arterial disease (PAD), anterior infarction, coronary heart disease with left main disease, PCI failure, cardiogenic shock, intra-aortic balloon (IAB), left ventricular ejection fraction (EF) <30%, door-toballoon time, symptoms-admission time. The independent predictors of death were: cardiogenic shock and EF < 30%. Were identified as predictors of MACCE: age, PAD, coronary heart disease with left main disease, PCI failure, cardiogenic shock, IABP and EF<30%. The independent predictors of MACCE were: PCI failure, ≥ two vessel disease, III or IV Killip class. Conclusion: The identification of adverse events high-risk groups will allow better adjustment of therapeutic strategy in the short and long term
