Metrics for analytics and visualization of big data with applications to activity recognition
No full textActivity recognition systems detect the hidden actions of an agent from sensor measurements made on the agents' actions and the environmental conditions. For such systems, metrics are important for both performance evaluation and visualization purposes. In this thesis, such metrics are developed and illustrated. For human activity recognition datasets, a reporting structure is described to visualize the metrics in a systematic manner. The other contribution of this thesis is to describe a visualization tool for estimating the orientation (attitude) of a rigid body from streaming motion sensor (accelerometer and gyroscope) data. A feedback particle filter (FPF) is implemented algorithmically to solve the estimation problem.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-05-01The student, Rohan Arora, accepted the attached license on 2016-04-25 at 10:47.The student, Rohan Arora, submitted this Thesis for approval on 2016-04-25 at 10:48.This Thesis was approved for publication on 2016-04-27 at 15:05.DSpace SAF Submission Ingestion Package generated from Vireo submission #9459 on 2016-07-07 at 14:17:57Made available in DSpace on 2016-07-07T21:18:02Z (GMT).

Primary pulmonary blastoma of monophasic variety- diagnosis and management
No full textPulmonary blastoma is a rare primary lung neoplasm, in that monophasic variety is far too rare. There are no specific clinical features seen for pulmonary blastoma; computed tomography and histopathology are diagnostic. Surgical excision is the treatment of choice; however, adjuvant chemotherapy and radiotherapy may be required in large and aggressive tumors
Fading correlation of co-located transmitters
No full textFading or attenuation of a signal due to environment is a phenomenon often encountered in wireless communications. It is expected that co-located transmitters i.e. transmitters placed very close to each other show a high signal fading correlation due to the presence of similar fading environment. In this thesis, we present an experimental study of this phenomenon. Correlation of received signal strengths obtained from co-located transmitters in dynamically varying environments indicate that the large scale signal variations (shadow fading) are highly correlated while the small scale variations (multipath or fast fading) show a low correlation. Highly correlated large scale variations suggest a presence of same large shadowing elements in the transmit-receive path while a low correlation among the multipath variations is due to mutual coupling between the antennas at very close distances. This has two implications: it suggests that shadow fading variations can serve as an indicator of the co-location of closely spaced transmitters while the multipath variations cannot. However, low multipath signal correlations suggest that antenna diversity could be investigated for implementation in mobile handsets.M.S.Includes bibliographical referencesby Prashant Jadha
Comparison of two nonlinear filtering techniques - the extended Kalman filter and the feedback particle filter
No full textIn a recent work it has been shown that importance sampling can be avoided in particle filter through an innovation structure inspired by traditional nonlinear filtering combined with optimal control and mean-field game formalisms. The
resulting algorithm is referred to as feedback particle filter (FPF).
The purpose of this thesis is to provide a comparative study of the feedback particle filter (FPF) with the extended Kalman filter (EKF) for a scalar filtering
problem which has linear signal dynamics and nonlinear observation dynamics. Different parameters of the signal model and observation model will be varied and performance of the two filtering techniques FPF, EKF will be compared.Item withdrawn by Mark Zulauf ([email protected]) on 2014-07-16T14:07:46Z

Comparison of nonlinear filtering techniques
No full textIn a recent work it is shown that importance sampling can be avoided in the
particle filter through an innovation structure inspired by traditional nonlinear
filtering combined with optimal control formalisms. The resulting algorithm is
referred to as feedback particle filter.
The purpose of this thesis is to provide a comparative study of the feedback
particle filter (FPF). Two types of comparisons are discussed: i) with the extended
Kalman filter, and ii) with the conventional resampling-based particle filters. The
comparison with Kalman filter is used to highlight the feedback structure of the
FPF. Also computational cost estimates are discussed, in terms of number of op-
erations relative to EKF. Comparison with the conventional particle filtering ap-
proaches is based on a numerical example taken from the survey article on the
topic of nonlinear filtering. Comparisons are provided for both computational
cost and accuracy.Item withdrawn by Mark Zulauf ([email protected]) on 2014-04-24T19:29:05Z

Feedback Particle Filter Algorithm for Simultaneous Localization and Map Building
No full textIn this thesis, feedback-particle-filter-based algorithms to solve the simultaneous
localization and map building (SLAM) problem are developed. Feedback particle
filter is a new formulation of the particle filter for the nonlinear filtering problem
based on the concepts from optimal control and mean-field game theory. A
software package is also developed.
The goal of SLAM is to compute the absolute location of a vehicle, starting
from an unknown location in an unknown environment by incrementally building
a map for the environment. Multiple landmarks are used to represent the environment.
Based on measurements of relative positions between the landmarks and
the vehicle, the absolute position of the vehicle is estimated simultaneously while
localizing the landmarks.Submitted by Janice Progen ([email protected]) on 2014-01-07T21:54:15Z

Job Satisfaction of Doctors in Tertiary Care Hospitals: A Study of North-Western Region of India
No full textThe physician satisfaction is of significance because of three reasons. First, physicians
happen to be one of the strongest stakeholders in health care system. As such a thorough
understanding of the factors affecting their satisfaction is critical to the emergence of a better
way of imparting healthcare. Second, there has been found to be a significant positive
relationship between physician satisfaction and patient satisfaction. Therefore greater physician
satisfaction may lead to higher patient satisfaction and consequently higher patient compliance
and better outcomes. Finally, understanding of physician satisfaction is inherently interesting in
itself. A strong and thorough insight into the physician satisfaction is valuable as it will help us
in identifying the factors contributing to physician satisfaction and thus enable us to counsel the
current physician and address the new entrants into the profession. This is may be very
significant as considerable time, effort and cost goes into training the physicians.
A plethora of factors have influenced the practice of medicine in unparallel ways throughout the
past decade. Presently Indian healthcare system comprises of many actors and organizations
intertwined in a fragile and changing relationships. The existing understanding about physicians’
insight of their job is significantly scarce in Indian milieu. There is not much understanding
about what drives and fulfills physicians about the practice of medicine or what influences their
behavior.
The purpose of this study is to develop a complete understanding of the factors that affect
physician satisfaction using self developed physician satisfaction scale. Eighty two item scale
representing eleven facets (comprised of sixty seven items) and three overall satisfaction
measures (fifteen items) was obtained through literature review. The refinement of the scale on
the basis of content validity, data quality and construct validity yielded a final instrument with
fifty one items constituting eight facets (forty three items) and two global measures (eight items)
of satisfaction. The internal consistency ranged between 0.776 to 0.907 - except autonomy which
had internal consistency of 0.639 (Mehta and Kiran 2015).
Regression analysis suggests certain demographic, work context and content factors influence
overall physician job and career satisfaction. In depth analysis provide an insight into the factors
that influence satisfaction in males, females, physicians employed in private and government
vii
hospitals. Correlation analysis indicates a strong and positive relationship between job and career
satisfaction. ANOVA indicates statistically significant difference in perception of physicians
employed in private and government hospitals towards job satisfaction. Also, it was found that
there is statistically significant difference in perception towards job satisfaction on the basis of
specialty. T-test indicated no statistically significant difference in job and career satisfaction of
physicians employed in private hospitals, while in case of physicians employed in government
hospitals the difference was significant. The results from this research might have significance
for the organizational structure of the practice of medicine in India. Given the prevalent concern
of high healthcare cost, restricted access to medical care for majority of the population, there
may be a need for changes
Voriconazole for the treatment of refractory <i> Aspergillus fumigatus</i> keratitis
No full textWe report a case of Aspergillus fumigatus keratitis in a 53-year-old, well-controlled diabetic female who did not respond to standard antifungal treatment. She was started on topical natamycin eye drops, but the infiltrate continued to progress. Topical amphotericin B and systemic ketoconazole was added, however, there was no response and the infiltrate increased further. She was then switched to topical and systemic voriconazole. Steady resolution of the infiltrate was noted within 2 weeks of therapy
