In electronics and electrical engineering, the form factor of an alternating current waveform (signal) is the ratio of the RMS (root mean square) value to the average value (mathematical mean of absolute values of all points on the waveform). [1] It identifies the ratio of the direct current of equal power relative to the given alternating ...
The Common Information Model (CIM) is an electric power transmission and distribution standard developed by the electric power industry. It aims to allow application software to exchange information about an electrical network. [1] It has been officially adopted by the International Electrotechnical Commission (IEC).
eGRID data is presented as an Excel workbook with data worksheets and a table of contents. The eGRID workbook contains data at the unit, generator, and plant levels and aggregated data by state, power control area, eGRID subregion, NERC region, and U.S. The workbook also includes a worksheet that displays the grid gross loss (%).
In certain business operations, taking a physical inventory is impossible or impractical. In such a situation, it is necessary to estimate the inventory cost. Two very popular methods are 1)- retail inventory method, and 2)- gross profit (or gross margin) method. The retail inventory method uses a cost to retail price ratio.
Electrical conductivity: σ: Measure of a material's ability to conduct an electric current S/m L −3 M −1 T 3 I 2: scalar Electric potential: φ: Energy required to move a unit charge through an electric field from a reference point volt (V = J/C) L 2 M T −3 I −1: extensive, scalar Electrical resistance: R: Electric potential per unit ...
Periodic inventory is a system of inventory in which updates are made on a periodic basis. This differs from perpetual inventory systems, where updates are made as seen fit. In a periodic inventory system no effort is made to keep up-to-date records of either the inventory or the cost of goods sold.
Up-to-date, real-time data on inventory conditions and levels is another advantage inventory management software gives companies. Company executives can usually access the software through a mobile device, laptop or PC to check current inventory numbers. This automatic updating of inventory records allows businesses to make informed decisions.
Generally this is accomplished by connecting the inventory system with order entry and in retail the point of sale system. In this case, book inventory would be exactly the same as, or almost the same, as the real inventory. In earlier periods, non-continuous, or periodic inventory systems were more prevalent. Starting in the 1970s digital ...
