This entry describes the components of the surface energy balance (SEB) over snow and ice: shortwave and longwave radiation, the turbulent fluxes of sensible and latent heat, and the subsurface (conductive) heat flux. If the surface is melting, the sum of these fluxes determines the melt rate.

On differential balancing: Energy functions and balanced realization
2015 European Control Conference (ECC), 2015In this paper, we present a novel balancing methodfor nonlinear systems in the contraction framework. We definetwo energy functions via variational systems. These novelcontrollability and observability functions can be used for modelreduction of nonlinear systems. We analyze their properties, usefor balancing, and application to model order reduction.

Energy balance or fat balance?
The American Journal of Clinical Nutrition, 1993Under normal conditions, carbohydrate, protein, and alcohol are not converted to fat. Glycogen and protein stores are closely controlled, and increasing the intake of nonfat nutrients stimulates their oxidation rates proportionally. Thus, chronic imbalance between intake and oxidation of nonfat nutrients cannot lead to obesity.

Measurements of energy balance
Acta Diabetologica, 2003Early investigators recognized a link between a mammal's rate of heat production and its body size and composition. A particular challenge has been to establish whether between- and within-species differences exist in the rate of cellular energy exchange, notably as resting metabolic rate.

An energy balance of front crawl
European Journal of Applied Physiology, 2005With the aim of computing a complete energy balance of front crawl, the energy cost per unit distance (C = Ev(-1), where E is the metabolic power and v is the speed) and the overall efficiency (eta(o) = W(tot)/C, where W(tot) is the mechanical work per unit distance) were calculated for subjects swimming with and without fins.

The sensory properties of foods and beverages are primary determinants of food choice. Some flavor components have an inherent hedonic valence that influences ingestive behavior. However, these hedonic impressions may be modified and others newly formed through their association with the post-ingestive consequences of food and beverage consumption ...

Energy efficiency is now the number one issue for many systems, determining weight and cost, and constraining performance. Many techniques have been developed to minimize the dynamic and static power consumed by digital designs without any impact on functionality.

Man is an energy machine able to convert food or body fuel stores to mechanical work. The efficiency of energy conversion to work can be calculated from the ratio of external work to internal energy conversion rate. In fed man, a small portion of heat is lost following the intake of food, and this is called the entropy or free energy of a foodstuff ...
