Stockage intersaisonnier de chaleurLe stockage saisonnier d'énergie thermique, stockage thermique intersaisonnier (ou STES pour seasonal thermal energy storage) est le stockage de chaleur ou de froid pour des périodes pouvant aller jusqu'à quelques mois. L'énergie thermique peut être recueillie partout où elle est disponible et être utilisée quand on en a besoin. Ainsi, la chaleur des capteurs solaires, la chaleur perdue des équipements d'air conditionné ou des processus industriels peut être collectée pendant la saison chaude et utilisée pour le chauffage quand elle est nécessaire, y compris pendant les mois d'hiver.
Thermal energy storageThermal energy storage (TES) is achieved with widely different technologies. Depending on the specific technology, it allows excess thermal energy to be stored and used hours, days, months later, at scales ranging from the individual process, building, multiuser-building, district, town, or region. Usage examples are the balancing of energy demand between daytime and nighttime, storing summer heat for winter heating, or winter cold for summer air conditioning (Seasonal thermal energy storage).
Symbolic regressionSymbolic regression (SR) is a type of regression analysis that searches the space of mathematical expressions to find the model that best fits a given dataset, both in terms of accuracy and simplicity. No particular model is provided as a starting point for symbolic regression. Instead, initial expressions are formed by randomly combining mathematical building blocks such as mathematical operators, analytic functions, constants, and state variables.
Liability (financial accounting)In financial accounting, a liability is defined as the future sacrifices of economic benefits that the entity is obliged to make to other entities as a result of past transactions or other past events, the settlement of which may result in the transfer or use of assets, provision of services or other yielding of economic benefits in the future.
Aircraft diesel engineThe aircraft diesel engine or aero diesel is a diesel-powered aircraft engine. They were used in airships and tried in aircraft in the late 1920s and 1930s, but were never widely adopted until recently. Their main advantages are their excellent specific fuel consumption, the reduced flammability and somewhat higher density of their fuel, but these have been outweighed by a combination of inherent disadvantages compared to gasoline-fueled or turboprop engines.
Debits and creditsDebits and credits in double-entry bookkeeping are entries made in account ledgers to record changes in value resulting from business transactions. A debit entry in an account represents a transfer of value to that account, and a credit entry represents a transfer from the account. Each transaction transfers value from credited accounts to debited accounts. For example, a tenant who writes a rent cheque to a landlord would enter a credit for the bank account on which the cheque is drawn, and a debit in a rent expense account.
