T he business environment is characterized by environmental and exogenous factors that affect company performance to the extent that it prevents managers from interacting effectively with a company. This study built on the literature on the ease of doing business and capital flight by empirically demonstrating the importance of business environments across different countries. To thi...

The structure of many standalone network intrusion detection systems (NIDSs) centers around a chain of analysis that begins with packets captured by a packet filter, where the filter describes the protocols (TCP/UDP port numbers) and sometimes hosts or subnets to include or exclude from the analysis. In this work we argue for augmenting such analysis with an additional, separately filtered stre...

In this paper we present three new schemes for sensor and actuator fault diagnosis for linear time-invariant systems: multirate parity-space techniques, multirate observers, and multirate detection filters. We show that these approaches offer distinct advantages over conventional fault diagnosis schemes in terms of ease of failure detection, the speed and the class of systems for which detectio...

power transformers are key components in electrical power supplies and their failure could cause severe consequences on continuity of service and also generates substantial costs. identifying problems at an early stage, before catastrophic failure occurs, is a great benefit for reliable operation of power transformers. frequency response analysis (fra) is a new, well-known and powerful diagnost...

The newly proposed in-plane resonant nano-electro-mechanical (IP R-NEM) sensor, that includes a doubly clamped suspended beam and two side electrodes, achieved a mass sensitivity of less than zepto g/Hz based on analytical and numerical analyses. The high frequency characterization and numerical/analytical studies of the fabricated sensor show that the high vacuum measurement environment will e...
