This paper considers the approach to the measurement of internal resistance of the battery in the uninterruptible power sources (UPSs [1]). Advantages of the approach are the measurements in power supplies without switching-off the battery, simplicity in realization of algorithm. The basic expressions of the theory used in the method about internal resistance of the storage battery are consider...

BACKGROUND Adequate sagittal plane motion of the first metatarsalphalangeal joint (1st MTPJ) is important during normal gait and goniometric measurement is commonly used as a diagnostic and outcome assessment tool. We aimed to determine the intra and inter-rater reliability together with the concurrent validity of a universal plastic goniometer (UG) and a smartphone applicationlication (Dr G) f...

PURPOSE The purpose of this study was to examine validity and reliability of Webel and colleagues' HIV Self-Management Scale when used with a Korean sample. METHODS The original 20-item HIV Self-Management Scale was translated into Korean using translation and back-translation. Nine HIV nurse experts tested content validity. Principal component analysis (PCA) and confirmatory factor analysis ...

Organizational justice has recently attracted attention as a predictor of employee mental and physical health. However, the lack of a Japanese translation of the original English-language organizational justice scale (OJS) has precluded its application in Japan. The present study aimed to develop Japanese version of the measure of organizational justice. We translated the original questionnaire...

Competitive audio consumer products require not only cheap signal processing hardware but also low-cost analog equipment and sound transducers. The nonlinear distortions produced by these electro-acoustic transmission systems cannot be described and analyzed by standard methods based on linear systems theory alone. In order to take the nonlinear properties into account, we present a measurement...

and budgets is growing. In response, reliability measurement has become a significant factor in quantitatively characterizing quality and determining when to release software on the basis of predetermined reliability objectives. In fact, some US Dept. of Defense organizations now require software reliability ineasurements. Motorola's World Wide Systems able as measured against an ever improving...

[Purpose] The purpose of this study was to examine test-retest reliability of the Good Balance system(®) for measurement of postural sway in poststroke patients. [Subjects] Sixty chronic stroke patients (40 men and 20 women; age 63.08 years; stroke duration 16.45 months) participated in this study. [Methods] Postural sway was evaluated using a force platform system (Good Balance system, Metitur...

Physical Unclonable Function (PUF) is the 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 (e.g, SRAM PUFs). In this paper, we propose the design of an ag...

Reliability is one of the highly significant quality indicators of object oriented software. Its proper measurement or evaluation, constantly facilitate and improve the software development process. On the other hand, reliability has always been a mysterious theory and its truthful measurement or evaluation is a complex exercise. Researchers and practitioners have always argued that reliability...
