Volterra Systems with Realizable Kernels
We compare an internal state method and a direct Runge-Kutta method for solving Volterra integro-differential equations and Volterra delay differential equations. The internal state method requires the kernel of the Volterra integral to be realizable as an impulse response function. We discover …

Electrophysiology, agent-based modeling and inverse optimal control applications in neuroethology
… integration of sensory information, motivational states and memory, from which assessment of outcomes and optimal action selection emerge. In foraging, animals tend to make decisions that reconcile two core goals: energy maximization and time minimization. The predatory sea-slug Pleurobranchaea …

Integration of Advanced Optics for Trapped Ion Quantum Information Processing
… trapped in a high vacuum poses a challenge. The internal state of the ion chosen for a quantum bit can be measured via exposure to a probe beam that causes one state to scatter light (a "bright" state), but not the other state (a "dark" state). In free space, a single ion acts like a point source …

Development and preliminary numerical investigations of a dislocation density-based finite-strain rate-dependent elastoplasticity constitutive model
… phenomena of interest. Such models make use of internal state variables that do not directly represent the associated evolution of the material microstructure, such as accumulated plastic strain. As a result, these models cannot directly provide microstructural information that may be of …

The design and engineering of variable character morphology
… has been implemented that allows a character's internal state to drive changes in its morphology. The system allows for real-time, multi-target blending between body geometries, skeletons, and animations. The results reflect qualitative changes in the character's appearance and state. Through …

Multiscale Modeling of the Deformation of Semi-Crystalline Polymers
… models are required. In this research, an internal state variable continuum model has been developed whose internal state variables (ISVs) and evolution equations are related to the nano-scale structures. Specifically, the ISVs represent entanglement number density, crystal number density, …

Connotational Subtyping and Runtime Class Mutability in Ruby
… dynamically, following changes to the object's internal state. This allows for a more precise representation of a problem domain with logical objects that have variable behavior. Two approaches to supporting connotational subtyping in the Ruby programming language were implemented: a …

Starved State Dependent Modulation of Olfactory Receptor Neuron Function in Drosophila melanogaster larvae
… information is often modulated by the animal's internal state such as hunger. The peripheral end of the olfactory circuit consists of first order olfactory receptor neurons (ORNs), that synapse onto the second order projection neurons (PNs), and regulatory local neurons (LNs) that innervate ORNs …

Finite element analysis of self-pierce riveting in magnesium alloys sheets
… through the use of the finite element method. An internal state variable (ISV) plasticity and damage material model was employed with results in good agreement to experimental data. The results of this study show that the ISV material model is ideally suited for modeling the SPR process in …

High current coaxial ion beam/laser beam spectrometer
… used. The laser beam induces transitions between internal states of the molecular ion. The transitions are detected by allowing the ion beam to collide with background gas and detecting the surviving ion beam current. Because the cross-section depends on the internal state of the ion, the …

Distributed state verification in the smart grid using physical attestation
… in a distributed system can fabricate its internal state in its communications with its peers. These state fabrications can cause other processes in the distributed system to make incorrect control decisions. Cyber-physical systems have a unique advantage in the detection of falsified …

Mentat: An Object-Oriented Macro Data Flow System
… macro actors are persistent and maintain their internal state between firings, and (2) program graph topology is dynamic. Mentat objects implement macro actors. Each object implements an actor for each member function of the object class. Mentat program graphs are constructed at run time.

Enlightened shelf awareness
… library secure, focus has shifted to improve the internal state of a library's collection, which is subjected daily to use and abuse by library patrons. In this thesis I present BookBot, a robot equipped with RFID readers, that automates the otherwise manual shelf-reading process and helps …

Brain-wide representations of behavior spanning multiple timescales and states in C. elegans
Changes in an animal’s behavior and internal state are accompanied by widespread changes in activity across its brain. However, how neurons across the brain encode behavior and how this is impacted by state is poorly understood. We recorded brain-wide activity and the diverse motor programs of …

Miniature Fiber Optic Viscoelasticity Sensor for Composite Cure Monitoring

Spatial instruction scheduling for raw machines
… mappings of instructions to time and space, the internal state of the scheduler maintains probabilities for different assignments of instructions to time and space resources. Second, a set of small scheduling heuristics cooperatively iterate over the probabilistic assignments many times in order …

A neuronal switch for approach/avoidance in cost-benefit decision
Animals make decisions by integrating their internal state, external sensory stimuli, and previous experiences. The neuronal bases of these decisions are accessible in the predatory sea- slug Pleurobranchaea, which has a very simple nervous system. Orienting and avoidance responses are dependent on …
