Predictive energy management strategies for hybrid electric vehicles applied during acceleration events

2019 Spring.Includes bibliographical references.The emergence and widespread adoption of vehicles with hybrid powertrains and onboard computing capabilities have improved the feasibility of utilizing predictions of vehicle state to enable optimal energy management strategies (EMS) to improve fuel economy. Real-world implementation of optimal EMS remains challenging in part because of limits on prediction accuracy and computation speed. However, if a finite set of EMS can be pre-derived offline, instead of onboard the vehicle in real time, fuel economy improvements may be possible using hardware that is common in current production vehicles. Acceleration events (AE) are attractive targets for this kind of EMS application due to their high energy cost, probability of recurrence, and limited variability. This research aims to understand how a finite set of EMS might be derived and applied to AEs based on predictions of basic AE attributes to achieve reliable fuel economy improvements. Models of the 2010 Toyota Prius are used to simulate fuel economy for a variety of control strategies, including baseline control, optimal EMS control derived via dynamic programming, and pre-derived control applied with approximate prediction to AEs. Statistical methods are used to identify correlations between AE attributes, optimal powertrain control, and fuel economy results. Then, key AE attributes are used to define AE categorization schemes of various resolutions, in which one pre-derived EMS is applied to every AE in a category. Last, the control strategies are simulated during a variety of drive cycles to predict real-world fuel economy results. By simulating fuel economy improvement for AEs both in isolation and in the context of drive cycles, it was concluded that applying pre-derived EMS to AEs based on predictions of initial and final velocity is likely to enable reliable fuel economy benefits in low-aggression driving

Seen in a New Light: Patterns of Adult Participation in Higher Education

This study identified length of time out of school and institutional support among the factors associated with the decision to enroll in a higher education degree program. The study suggests that considering participation in the context of social capital can help adult educators better understand enrollment decisions

Session A1- Basinwide approaches to prioritizing stream connectivity projects

Repairing, removing and retrofitting barriers (e.g., installing fish ladders) are seen as some of the most effective and cost-efficient means of habitat restoration available. However, in spite of the potential benefits, surprisingly little has been done with regard to the development of quantitative/analytic planning methods for prioritizing barrier repair and removal decisions. Our presentation will summarize efforts under way since 2006 to bring together state and federal agencies and non-governmental organizations to build an inventory of fish passage barriers in Maine. We will present systemic methods for prioritizing the repair or removal of fish passage barriers for diadromous and resident fishes. Working with a variety of partners, we have developed GIS tools and budget-constrained optimization models for deciding which barriers to repair or remove in order to maximize habitat availability for stream resident fish and diadromous fish species

Erk1/2 Mediates Leptin Receptor Signaling in the Ventral Tegmental Area

Leptin acts on the ventral tegmental area (VTA) to modulate neuronal function and feeding behavior in rats and mice. To identify the intracellular effectors of the leptin receptor (Lepr), downstream signal transduction events were assessed for regulation by direct leptin infusion. Phosphorylated signal transducer and activator of transcription 3 (pSTAT3) and phosphorylated extracellular signal-regulated kinase-1 and -2 (pERK1/2) were increased in the VTA while phospho-AKT (pAKT) was unaffected. Pretreatment of brain slices with the mitogen-activated protein kinase kinase -1 and -2 (MEK1/2) inhibitor U0126 blocked the leptin-mediated decrease in firing frequency of VTA dopamine neurons. The anorexigenic effects of VTA-administered leptin were also blocked by pretreatment with U0126, which effectively blocked phosphorylation of ERK1/2 but not STAT3. These data demonstrate that pERK1/2 may have a critical role in mediating both the electrophysiogical and behavioral effects of leptin receptor signaling in the VTA

Experimental limits on monojet production in e+e- annihilation at 29 GeV

A search was made for e+e--->X1X2 where X1 consists of one or more light unobservable particles and X2 decays promptly to a visible jet of particles. One event was found for an integrated luminosity of 176 pb-1, a rate consistent with known backgrounds. This result places a significant constraint on a number of theoretical models.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25641/3/0000191.pd
