ENVELOPE ELEGY
… poems in this thesis fall under the heading, “Envelope Elegy.” To me, this title suggests something I think a good majority of poems examine: what would it mean to miss or lose something that is just about to disappear but has not yet done so? These poems wrestle with this element of the human …

Relational envelope-based planning
… on this initial plan. Our approach uses the envelope MDP framework, which creates a Markov decision process out of a subset of the possible state space. This strategy lets an agent begin acting quickly within a restricted part of the full state space, as informed by the original plan, and to …

Spectral envelope estimation for transient event detection
… and identifying transient events in the spectral envelopes of the current waveform measured at the utility service entry. The spectral envelopes of the current waveform are the coefficients of its time varying Fourier series representation and as such can be estimated by low-pass filtering the …

Durability and waterproofing investigations of the building envelope
Durability of the building envelope is an important characteristic to monitor and test on a structure to ensure it does not fail prematurely from water penetration. Due to the building envelop failures existing today, the described testing herein aims to evaluate different building components in an …

Novel plant nuclear envelope-associated coiled-coil proteins
The nuclear envelope (NE) is a double lipid bilayer enclosing the eukaryotic genome. The metazoan nucleoskeleton includes the peripheral lamina and the internal nucleoskeleton. The lamina is composed of a network of intermediate filament (IF) proteins called lamins, as well as lamin- and/or …

Biology of the envelope glycoproteins of sheep betaretroviruses
Retroviruses possess several biological features that differentiate them from all other infectious agents. The obligatory integration step of the retrovirus genome into the host genome has allowed these viruses to associate, modulate and alter the biology of the cell with a variety of unique …

Flight envelope protection using flap hinge moment measurement
An experimental investigation of the sensitivity of flap hinge moment to airfoil surface contamination was conducted at the University of Illinois at Urbana-Champaign Aerodynamics Research Lab. Tests were conducted on two airfoil models, an NACA 3415 and an NACA 23012, at Reynolds numbers of 1.8 × …

Neural coding of sound envelope in reverberant environments
… on temporal modulations in the amplitude envelope of the speech signal. Reverberation encountered in everyday environments can substantially attenuate these modulations. To assess the effect of reverberation on the neural coding of amplitude envelope, we recorded from single units in the …

Electrical-phenotyping of the bacterial envelope using microfluidics
The bacterial cell envelope is a complex multi-layered covering, crucial for cell viability and physiological capabilities. Phenotypic analysis of bacterial envelopes is challenging due to the small size and low cultivability of microbes. The emerging microfluidic techniques enable quantitative and …

Changes in muskmelon perisperm envelope tissue during germination
… The embryonic axis must penetrate the perisperm envelope (perisperm + endosperm) for germination to occur. Radicle emergence could result from increased turgor, weakening of the perisperm tissue, or a combination of both. In a previous report, turgor of the embryonic axis did not increase prior …

Inflated cylindrical envelope subjected to axial compressive load
… end shortening of an inflated cylindrical fabric envelope subjected to axial compression, by the energy method. A cylindrical shape is selected because sphere and cylinder are considered more general in use and more easily to be treated than any other geometrical shapes. Also, for the sake of …

Bulk properties and physical characteristics of stripped-envelope supernovae
Stripped-envelope supernovae (SE-SNe) are a subset of core-collapse supernovae; the explosive death of a massive star. Their defining characteristic is the lack of promi- nent He and/or H envelope suggesting significant mass loss prior to explosion. Their progenitors may be high mass single stars …

Envelope tracking integral equation based hybrid electromagnetic circuit simulators
This dissertation presents envelope-tracking hybrid field-circuit simulator for efficiently analyzing narrowband scattering from distributed structures loaded with nonlinear devices. The simulator models the interactions of fields with distributed structures and lumped elements by coupling and …
