The magnetic gradient full-tensor measurement system is diverse, and the magnetometer array structure is complex. Aimed at the problem, seven magnetic gradient full-tensor measurement system models are studied in detail. The full-tensor measurement theories of the tensor measurement arrays are analyzed. Under the same baseline distance, the magnetic dipole model is used to simulate the measurement system. Based on different measurement systems, the paper quantitatively compares and analyzes the error of the structure. A more optimized magnetic gradient full-tensor measurement system is suggested. The simulation results show that the measurement accuracy of the planar measurement system is slightly higher than that of the stereo measurement system. Among them, the cross-shaped and square measurement systems have relatively smaller structural errors and higher measurement accuracy.

The purpose of this study is to investigate computing professionals’ perspectives on services offered by a professional association. A conceptual framework was developed based on a review of relevant literatures to explore the motivations of professionals to join and maintain professional association membership. A survey instrument was developed based on the conceptual framework, and was subsequently deployed within the Association of Information Technology Professionals (AITP). The analyses (N = 220) include descriptive analyses, exploratory factor analysis, and internal consistency reliability analyses. The results suggest that members’ needs and motivations are multidimensional, involving ten distinct and internally consistent underlying constructs. This paper contributes by providing a reliable measurement system for computing professional association leadership to make informed decisions and provides substantive recommendations for offering targeted services. The findings suggest that important aspects of computing professional membership are networking with local professionals, professional development programs, and promoting their concerns.
