Short for ground penetrating radar, a UWB imaging technology used for subsurface earth exploration. GPR uses electromagnetic wave propagation and scattering to image and identify changes in electrical and magnetic properties in the ground. GPR systems have wide applications, such as locating underground utility lines, monitoring airplane runways for structural integrity, detecting unexploded land mines, conducting groundwater studies or forensic research and surveying land for construction purposes.
The FCC has mandated that GPR must operate below 960 MHz or in the frequency band 3.1-10.6 GHz and a GPR system can only operate when in contact with or in close proximity to the ground for the purpose of detecting and imaging subsurface anomalies, such as buried objects, sinkholes or underground caves and fluctuations in the earth’s composition. The FCC has limited GPR operation to law enforcement, fire and rescue organizations, scientific research institutions, commercial mining companies and construction companies.
- General Packet Radio Service (GPRS)
Short for General Packet Radio Service, a standard for wireless communications which runs at speeds up to 115 kilobitsper second, compared with current GSM (Global System for Mobile Communications) systems’ 9.6 kilobits. GPRS, which supports a wide range of bandwidths, is an efficient use of limited bandwidth and is particularly suited for sending and receiving […]
Acronym for GUID partition table Computers with an Intel Itanium processor use the Extensible Firmware Interface (EFI) between firmware, hardware, and OS. EFI has a new type of disk partitioning system, called the GUID (globally unique identifier) partition table (GPT). Unlike Master Boot Record (MBR) partitioned disks, data critical to platform operation is located in […]
- Graphics Processing Unit (GPU)
A GPU, or graphics processing unit, is used primarily for 3-D applications. It is a single-chip processor that creates lighting effects and transforms objects every time a 3D scene is redrawn. These are mathematically-intensive tasks, which otherwise, would put quite a strain on the CPU. Lifting this burden from the CPU frees up cycles that […]
- GPU clock
GPU clock is the graphics processor unit’s (GPU) clock speed, measured in megahertz (MHz). Also called Engine clock.
Acronym for General Responsibility Assignment Software Patterns. GRASP provides guidance for assigning responsibilities to classes and, to a limited extent, determining the classes that will be in a design in an object-oriented system.
