Managing the aging of digital control systems ensures that nuclear power plant systems are in adequate safety margins during their life cycles. Software is a core component in the execution of control logic and differs between digital and analog control systems. The hardware aging management for the digital control system is similar to that for the analog system, which has matured over decades ...

—Modulated Wideband Converter (MWC) is a type of theory to real-time sub-Nyquist sampling and recovery of sparse wideband analog signal with low computational overhead and efficient hardware implementation. However, the application and implementation of MWC are seriously disturbed by the measurement matrix mismatch problem caused by limited system bandwidth and inevitable nonlinearity of pract...

In this paper we address the development, testing, and evaluation schemes for software reliability, and the integration of these schemes into a unified and consistent paradigm. Specifically, techniques and tools for the three phases of software reliability engineering will be described. The three phases are (1) modeling and analysis, (2) design and implementation, and (3) testing and measuremen...

Physical Unclonable Function (PUF) is hardware analog of a one-way function which can address hardware security issues such as device authentication, generating secret keys, producing seeds for Random Number Generators, etc. Traditional silicon PUFs are based on delay (Ring Oscillator PUFs and Arbiter PUFs) or memory structures (like SRAM). In this paper, we propose a novel idea of a very fast,...

Introduction One of the major concerns in the construction of test items for an examination is ensuring the reliability of the test items. In order for assessments to be sound, they must be free of bias and distortion. Reliability and validity are two concepts that are important for defining and measuring bias and distortion. Internal consistency is an estimate of reliability based on the avera...

Based on the damage mechanics theory, summarized a new dynamic reliability calculation method with explicit physical meaning, which is used for researching structural dynamic reliability on cyclic stress. By using of the model of stress-strength interference, ignoring the effects of erosion and aging on the strength degradation, only consider that the change of damage leads to the effective str...

Objective: Postoperative fatigue is an undesired and discouraging symptom that many patients experience after the surgery operation. Good assessment essential to detect manage this symptom. There no specific Turkish validity reliability measurement tool assess postoperative fatigue. In study, it was conducted adapt Fatigue Scale (PO-FS) in order evaluate fatigue.
 Methods: Methodological s...

This paper details possible extensions and also limitations of the Aravind Hypothesis for comparing quantum measurement with classical topological measurement. We detail a separate, network model for quantum evolution and measurement, where the background space is replaced by an evolving network. In this model there is an analog of the Aravind Hypothesis that promises to directly illuminate rel...

tac (time to amplitude convertor) is one of the most important time measurement instrumentswhich has great significance in many fields of science, especially radiation physics. a tac unit has beendesigned based on the start-stop analog method and nim (nuclear instrument modules) standards. afterdesigning the circuit, it was simulated by pspice software and constructed by discrete and integrated...
