Abstract: A facility providing systems and methods for managing and optimizing energy consumption and/or production is provided. The facility provides techniques for optimizing energy-consuming and energy-producing systems to meet specified demands or goals in accordance with various constraints. The facility relies on models to generate an optimization for an energy system. In order to use generic models to simulate and optimize energy consumption for an energy system, the generic models are calibrated to properly represent or approximate conditions of the energy system during the optimization period. After the appropriate models have been calibrated for a given situation using one or more modeling parameter sets, the facility can simulate inputs and responses for the corresponding system. The facility uses the generated simulations to generate a plan or control schedule to be implemented by the energy system during the optimization period.

Abstract: One or more devices, systems and/or methods for generating waste profiles are provided. For example, a graphical user interface may be controlled to display a waste profile interface. A request to generate a waste profile associated with waste may be received via the waste profile interface. The request may comprise waste parameters of the waste. One or more waste information databases may be analyzed to identify data records associated with the waste parameters. The waste profile may be generated based upon the waste parameters and the data records. An electronic waste transfer request, comprising the waste profile, associated with the waste, may be transmitted over a network connection to a second device associated with a waste facility. An acceptance message indicating that the waste facility accepts the waste or a rejection message indicating that the waste facility rejects the waste may be received from the second device.

Abstract: A multidirectional runner assembly for positioning a carrier pipe within a surrounding casing pipe. Each multidirectional runner assembly has at least one ball transfer assembly at least partially protruding from the runner assembly, in order to contact an inner surface of a surrounding casing pipe. The ball transfer assemblies reduce static and/or kinetic friction forces during installation of a carrier pipe within the central bore of a casing pipe, permit multidirectional orientation of the runners within the casing pipe, and provide greater load support.

Abstract: A retainment device may have a retainment vessel with a first section and a second section that, when joined, form a hollow retainment device.

The retainment device is preferably transparent and enables one to attach it to various items such as a bottle stopper or a keychain. Items may be stored within the retainment vessel and viewed therethrough. A tag mechanism may allow a description of the object contained within the retainment mechanism to be identified.

Abstract: Ionic cyclic nitroxyl radical oligomers, methods of making the ionic cyclic nitroxyl radical oligomers, and electrochemical cells, such as aqueous organic redox flow batteries (AORFBs) that use the ionic nitroxyl radical oligomers as catholytes are provided. The oligomers are larger than individual cyclic nitroxyl radical molecules, but maintain a high density nitroxyl radical groups within the molecule. As a result, when the oligomers are used as catholytes in an AORFB, they are able to reduce catholyte permeation through the ion-conducting membrane, while providing a high volumetric capacity and cycling stability.
