What Are Active Instruments? Active instruments are the instruments in which the quantity to be measured activates the magnitude of external power input source that produces the measurement. An example of an active instrument is a float-type petrol-tank level indicator. In this instrument, the change in petrol level moves a potentiometer arm and the output … Read more
What Is A Router? A router is a networking device that forwards data packets between computer networks. Data sent through the internet such as a web page or email is often in the form of data packets. Routers perform the traffic directing functions on the internet. A router inspects a given data packet’s destination IP … Read more
What Is Nickel? Nickel is a naturally-occurring metallic element with a silvery-white, shiny appearance. It is the fifth-most common element on earth and occurs extensively in the earth’s crust and core. Nickel along with iron is also a common element in meteorites and can even be found in small quantities in plants, animals and seawater. … Read more
High-Level Data Link Control (HDLC) HDLC (High-level Data Link Control) is a group of protocols or rules for transmitting data between network points, sometimes referred to as nodes. In HDLC, data is organized into a unit called frame and sent across a network to a destination that verifies its successful arrival. The HDLC frames consist … Read more
What Is Hot Working? Hot working process metals are plastically deformed above their re-crystallization temperature. Being above the re-crystallization temperature allows the material to re-crystallize during formation. This is important because re-crystallization keeps the materials from strain hardening which ultimately keeps the yield strength and hardness low and ductility high. The ultimate goal of metal … Read more
What Is Static SQL? Static SQL are statements in an application that do not change at runtime (when source code is written) and therefore can be hard-coded into the application. Static SQL is referred to as static because the SQL statements in the program do not change each time the program is run. Static SQL … Read more
Numerical Control (NC) Machine Numerical control, commonly referred to as NC, is a machine which is controlled by the set of instructions in the form of numbers, letters and symbols. In this case, the set of instruction is referred to as program. NC is essential to the operation of modern industrial robots. The two basic … Read more
Spreadsheet A spreadsheet is a computer application for organization, analysis and storage of data in tabular form. The program operates on data entered in cells of a table. Each cell contains either numeric or text data or the results of formulas that automatically calculate and display a value based on the contents of other cells. … Read more
What Are Lists In Python? A list is a data structure in Python that is a mutable or changeable, ordered sequence of elements. Each element or value that is inside a list is called an item. Lists are mutable. This means that you can modify a list after it has been initialized i.e you can … Read more
A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. That is, it is a spanning tree whose sum of edge weights is less than or equal to the weight of every other spanning tree. More … Read more
