The personal consumption expenditure ( PCE) measure is the component statistic for consumption in gross domestic product (GDP) collected by the United States Bureau of Economic Analysis (BEA). It consists of the actual and imputed expenditures of households and includes data pertaining to durable and non-durable goods and services.
In computer networks, a path computation element (PCE) is a system component, application, or network node that is capable of determining and finding a suitable route for conveying data between a source and a destination. [1] Description. Routing can be subject to a set of constraints, such as quality of service (QoS), policy, or price.

Polynomial chaos expansion (PCE) provides a way to represent a random variable with finite variance (i.e., ) as a function of an -dimensional random vector , using a polynomial basis that is orthogonal with respect to the distribution of this random vector. The prototypical PCE can be written as:

Tetrachloroethylene, also known under the systematic name tetrachloroethene, or perchloroethylene, [a] and abbreviations such as " perc " (or " PERC "), and " PCE ", is a chlorocarbon with the formula Cl2C=CCl2. It is a colorless liquid widely used for dry cleaning of fabrics, hence it is sometimes called " dry-cleaning fluid ".

The most efficient bandgap is found to be at 1.34 eV, with a maximum power conversion efficiency (PCE) of 33.7%. Reaching this ideal bandgap energy can be difficult, but utilizing tunable perovskite solar cells allows for the flexibility to match this value.
Policy is set to maintain a very low rate of inflation or deflation. For example, the European Central Bank (ECB) describes price stability as a year-on-year increase in the Harmonised Index of Consumer Prices (HICP) for the Euro area of below 2%.
