UAV Group Autonomy In Network Centric Environment
(2016-11-23)It is a well-recognized fact that unmanned aerial vehicles are an essential element in today’s network-centric integrated battlefield environment. Compared to solo UAV missions, multiple unmanned aerial vehicles deployed ... -
Ultra High Compression For Weather Radar Reflectivity Data
(2007-10-09)Weather is a major contributing factor in aviation accidents, incidents and delays. Doppler weather radar has emerged as a potent tool to observe weather. Aircraft carry onboard radars but their range and angular resolution ... -
Ultrasonic Guided Wave Based Models, Devices and Methods for Integrated Structural Health Monitoring
(2018-01-31)Structural Health Monitoring (SHM) systems for future structures and vehicles would involve a process of damage identification and prediction of certain quantities of interest that concerns the function and safety. This ... -
Uncertainty Analysis of Microwave Based Rainfall Estimates over a River Basin Using TRMM Orbital Data Products
(2018-01-11)Error characteristics associated with satellite-derived precipitation products are important for atmospheric and hydrological model data assimilation, forecasting, and climate diagnostic applications. This information also ... -
Uncertainty Based Damage Identification and Prediction of Long-Time Deformation in Concrete Structures
(2018-02-20)Uncertainties are present in the inverse analysis of damage identification with respect to the given measurements, mainly the modelling uncertainties and the measurement uncertainties. Modelling uncertainties occur due to ... -
Uncertainty modeling and analysis of aerospace structures
Aerospace structures are different from other structures due to the difference in the required properties for an aerospace application. The primary motivation of this kind of structure lies in its lightweight nature, ... -
Uncertainty Modeling For River Water Quality Control
(2010-08-30)Waste Load Allocation (WLA) in rivers refers to the determination of required pollutant fractional removal levels at a set of point sources of pollution to ensure that water quality standards are maintained throughout the ... -
Uncertainty Quantification in Flow and Flow Induced Structural Response
(2018-07-23)Response of flexible structures — such as cable-supported bridges and aircraft wings — is associated with a number of uncertainties in structural and flow parameters. This thesis is aimed at efficient uncertainty quantification ... -
Understanding And Supporting Conceptual Design Synthesis Of Multiple State Mechanical Devices
(2015-08-07)Conceptual design synthesis is part of the conceptual phase of the design process, which focuses on creating alternative, candidate solutions. Conceptual design phase has the greatest influence on the cost and characteristics ... -
Understanding Catchment Scale Processes: Hydrological Modelling and Information-Theoretic Approaches
Catchments are complex environmental systems, and they serve as the fundamental units for hydrological classification. They are self-organizing systems whose form, drainage network, ground and channel slopes, channel ... -
Understanding Context In Designing
(2009-05-25)Everything around us that is not a simple untouched piece of nature has been designed by someone. Human society has found a great refuge in these designed objects or the artefacts, and thus has adapted vociferously to their ... -
Understanding deformation mechanisms in the Hall-Petch breakdown regime of Ni-W alloys
The substantially higher strengths of nanocrystalline metals has been to attributed to the well-known Hall-Petch relationship σ= σ_o+k_HP d^(-1/2) where 𝜎 is the yield stress, 𝜎𝑜 is the lattice friction stress, 𝑑 is ... -
Understanding High Speed Mixing Layers with LES and Evolution of Urans Modeling
(2017-11-15)This thesis is concerned with studies on spatially developing high speed mixing layers with twin objectives: (a) to provide enhanced and detailed understanding of spatial development of two-dimensional mixing layer emanating ... -
Understanding Knowledge Needs And Processes In Design
(2011-01-31)In this knowledge economy, organizations are leveraging their competence through the knowledge they possess. Managing knowledge will potentially retain the competence held by the organization if knowledge generated across ... -
Understanding Structure And Growth Of Physisorbed Films : A Combined Atomic Force Microscopy And Modeling Study
(2014-10-16)Surface modification has wide ranging implications in lubrication, microelectromechanical systems (MEMS), colloidal systems and biological membranes. Surface modification plays an important role in stabilizing gold ... -
Understanding the demixing behavior and structure-property correlation in graphene oxide containing LCST blends
A number of researchers have studied about the effects of different nanoparticles on the phase separation of LCST polymer blend systems. Many nanoparticles such as carbon nanotubes and silica have been incorporated in ... -
Understanding the dynamics and evolution of cratons
The earth is the only rocky planet in the solar system that exhibits plate tectonics. One of the basic tenets of plate-tectonics is that it recycles the lithosphere within a few hundred million years. No oceanic lithosphere, ... -
Understanding the interplay between immune response and virus evolution
RNA viruses are the underlying cause of many human diseases, including the common cold, influenza, dengue fever, and COVID-19. Their ability to evolve rapidly makes them challenging to tackle, resulting in public health ... -
