Current state-of-the-art linear parameter-varying (LPV) control design methods presume that an LPV state-space (SS) model of the system with affine dependence on the scheduling variable is available. However, many existing LPV-SS identification schemes either suffer heavily from computational issues related to the curse of dimensionality or are based on severe approximations. To overcome these issues,...
Diseases which are prevalent in the gastrointestinal (GI) tract, such as Crohn's disease, are a topic of increasing concern because diagnosis and specific treatment are difficult and may be ineffective. New techniques are therefore sought after and this paper describes a proof-of-concept tethered capsule for targeted drug delivery (TDD) in the GI tract. The capsule consists of a camera, illumination,...
Studies have been done and continue on the design and construction of a Shashlik detector using Radiation hard quartz capillaries filled with wavelength shifting liquid to collect the scintillation light from LYSO crystals for use as a calorimeter in the Phase II CMS upgrade at CERN. The work presented here focuses on the studies of the capillaries and liquids that would best suit the purpose of the...
This paper discusses an improvement on the extension of linear subspace methods (originally developed in the Linear Time-Invariant (LTI) context) to the identification of Linear Parameter-Varying (LPV) and state-affine nonlinear system models. This includes the fitting of a special polynomial shifted form based LPV Autoregressive with eXogenous input (ARX) model to the observed input-output data....
Collaborations that involve the sharing of medical and biométrie data between government and industry partners present particular ethical challenges. In this paper, ethical implications of data sharing and recommendations for data management in these collaborations are identified. Recommendations for adhering to privacy laws and examples of government-industry collaborations using medical or biométrie...
The exchange of medical and biometric data across borders can present ethical concerns and dilemmas. This paper provides examples of existing national and international normative frameworks, including binding legislation and non-binding guidelines on international data sharing, to illustrate the status quo and cross-national inconsistencies. Ethical implications of these normative frameworks and of...
In this paper, ethical implications of data collection, use and retention of medical and biometric data in biometrics and medical applications are identified. These implications are discussed in the context of five main ethical principles - privacy, confidentiality, security, property and ownership, and reliability and trustworthiness. In addition, to illustrate unethical uses of medical and biometric...
While the information infrastructure to support public health and health research has been dramatically improving, comprehensive, nation-wide, longitudinal, person-centered information has been generally nonexistent. Yet, having such information for large populations is essential to public health and health research. The coupling of internet access, information standards and emerging electronic health...
There is a significant number of IT failures per year because parts fail, products are used in ways they were not designed for, and humans make errors in using products. These failures result in incidents that product vendors service as a part of the warranty or contracts. Incidents incur significant costs for servicing them, including call centers, parts, and field engineers. Some of the major problems...
Unlike other diversity-based approaches, N-variant systems thwart attacks without requiring secrets. Instead, they use redundancy (to require an attacker to simultaneously compromise multiple variants with the same input) and tailored diversity (to make it impossible to compromise all the variants with the same input for given attack classes). In this work, we develop a method for using data diversity...
An automatic guitar tuner was successfully designed and developed using a fuzzy logic controller. The guitar tuner was implemented using Simulink and XPC real time kernel. The system acquires the signal from an electrical guitar and inputs the signal into a target PC running XPC. Using fast Fourier transforms (FFT), the system calculates the fundamental and harmonics of the played notes and compares...
When uniform-field, impulse electric strength measurements were made in different laboratories on liquids having ostensibly the same composition, the resulting values of electric strength often differed by as much as a factor of seven. To resolve this discrepancy, a study of the problem revealed that differences in the following experimental conditions might be responsible for the divergence of results:...
In our investigation of the mechanism of electric breakdown in liquids, we have endeavored to measure a value for the electric strength that is characteristic of the liquid itself; ideally, that value which is free from the influence of all external factors such as electrode composition, surface condition, and configuration. However, because the influence of such factors as these cannot be completely...
A broad-band spectral analysis was undertaken of the dielectric properties of ferrites (polarization, magnetization and conduction) from d.c. to the optical spectral region. After a short description of the various measurement techniques employed, characteristic data are given of electronic conduction, space-charge polarization, infrared absorption, and ferromagnetic resonance. Various additional...
