Robust adaptive sampled-data control design for MIMO systems: Applications in cyber-physical security
This dissertation extends the L1 adaptive control theory to sampled-data (SD) framework. Multi-input multi-output non-square (underactuated) systems are considered with different sampling rates for inputs and outputs. The sampled-data framework allows to address non-minimum phase systems, subject …

A new constraint-based algorithm to learn Bayesian network structure from data: Control of Spurious Pairwise Information (CSPI)
… However, learning the network structure from data requires an exponential number of conditional independence tests; several algorithms have been proposed in order to reduce the runtime of this procedure. We present a new constraint-based algorithm for learning Bayesian network structure from …

Analysis and techniques of data compression in smart grids in the context of IEC 61850 communication protocol
… electronic devices (IEDs) typically record the data and share the information across each level of the grid. In distribution substations, the data and hence the information is then further transferred throughout the supervisory control and data acquisition (SCADA) and the data control center …

Mentor characteristics and protégé/mentor perceptions of mentoring functions and quality in Korean companies
… to level of mentoring functions and quality. The data were collected through an online survey with new employees (i.e., protégés) and their mentors who participated in a formal mentoring program at one Korean IT company in Korea in 2009. A total of 392 employees and their mentors were invited to …
