Dataframe may refer to: A tabular data structure common to many data processing libraries: pandas (software) § DataFrames; The Dataframe API in Apache Spark;
Values of type rotational speed, voltage, frequency, electric current, etc. SDO: Service Data Object - Configuration settings, possibly node ID, baud rate, offset, gain, etc. COB-ID: Communication object identifier; CAN ID: CAN Identifier. This is the 11-bit CAN message identifier which is at the beginning of every CAN message on the bus.
When the MAC drives the MDIO line, it has to guarantee a stable value 10 ns (setup time) before the rising edge of the clock MDC. Further, MDIO has to remain stable 10 ns (hold time) after the rising edge of MDC. When the PHY drives the MDIO line, the PHY has to provide the MDIO signal between 0 and 300 ns after the rising edge of the clock. [1]
The OPC Data Access Specification is the first of a group of specifications known as the OPC Classic Specifications. [1]OPC Data Access is a group of client–server standards that provides specifications for communicating real-time data from data acquisition devices such as PLCs to display and interface devices like Human–Machine Interfaces (HMI), SCADA systems [2] and also ERP/MES systems.

SQL includes operators and functions for calculating values on stored values. SQL allows the use of expressions in the select list to project data, as in the following example, which returns a list of books that cost more than 100.00 with an additional sales_tax column containing a sales tax figure calculated at 6% of the price.
In particular, task pull parallelism has better performance for Rmpi in heterogeneous computing environments. The idea of SPMD parallelism is to let every processor do the same amount of work, but on different parts of a large data set.
This overpowers one of the 15 kΩ pull-down resistors in the host and leaves the data lines in an idle state called J. For USB 1.x, the choice of data line indicates what signal rates the device is capable of: full-bandwidth devices pull D+ high, low-bandwidth devices pull D− high. The K state has opposite polarity to the J state.
1.1 All outputs pull-ups and current sources are switched off 1.2 The bus current is measured, I offset. 2 Pull-up mode 2.1 Pull-ups are turned on and current sources remain off 2.2 The bus current is measured, I PU 2.3 Nodes with ΔI = I PU-I offset < 1 mA are "selected" 3 Current source mode
