Development of Contactless Sand Production Test Instrument

Development of Contactless Sand Production Test Instrument

Background: Sand production is an important factor affecting reservoir exploitation. Excessive sand production affects the oil well life, causes the damage to the oil recovery device and brings serious hidden danger in the process of safety production. Objective: This paper presents a sand content computation model for the crude oil, which uses the power of sand production and Parseval theorem,...

Development and Validation of Successful Aging Instrument

Objectives: Successful aging is an interdisciplinary concept. Despite the great body of literature on successful aging, few studies have focused on its subjective and multidimensional measurements. Thus, the present study aimed to develop an instrument to measure self-perceived successful aging. Methods: We used a mixed method approach. The successful aging dimensions were explored through an ...

Developing Sustainable IT-Related Capabilities: Instrument Development and Test

Research has established that firms’ IT-related capabilities at a point in time explain IT-related performance differences across firms. IT resources, however, are dynamic, and evolve at an exponential rate. This means we need to understand how to sustain firms’ existing capabilities to leverage opportunities offered by new IT resources. Wet suggests a higher-level resource that can sustain fir...

Development of a Novel Contactless Mechanocardiograph Device

A novel method of detecting mechanical movement of the heart, Mechanocardiography (MCG), with no connection to the subject's body is presented. This measurement is based on radar technology and it has been proven through this research work that the acquired signal is highly correlated to the phonocardiograph signal and acceleration-based ballistocardiograph signal (BCG) recorded directly from t...
