Engineering

Big data Big data is a term for data sets that are so large or complex that traditional data processing applications are inadequate. Challenges include analysis, capture, data curation, search, sharing, storage, transfer, visualization, querying and information privacy. The term often refers simply to the use of predictive analytics or certain other advanced methods to extract value from data, and seldom to a particular size of data set. Accuracy in big data may lead to more confident decision making, and better decisions can result in greater operational efficiency, cost reduction and reduced risk.
Internet of Things (IoT) The Internet of Things (IoT) is the network of physical objects—devices, vehicles, buildings and other items—embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data. The IoT allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit; when IoT is augmented with sensors and actuators, the technology becomes an instance of the more general class of cyber-physical systems, which also encompasses technologies such as smart grids, smart homes, intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure.
CAD CAD (computer-aided design) means the design of a product using EDP. Originally CAD described the use of a computer as an auxiliary aid to technical drawing.
LTE Long Term Evolution (LTE) is a fourth generation mobile communications standard.
HSDPA High Speed Downlink Packet Access (HSDPA, 3.5G, 3G+ or UMTS-Broadband) is a UMTS mobile communications standard data transfer process defined by the 3rd Generation Partnership Project . The process enables data transfer rates within mobile communications networks similar to those achieved by DSL.
EDGE Enhanced Data Rates for GSM Evolution (EDGE) describes a technology aiming at increasing the data transfer rate in GSM mobile communications networks by introducing an additional modulation process. With EDGE, the GPRS data services are enhanced to become E-GPRS (Enhanced GPRS) and HSCSD to ECSD.
UMTS The Universal Mobile Telecommunications System (UMTS) is a third generation (3G) mobile communications standard.
SolidEdge Solid Edge is a 2D/3D-CAD system. In order to allow flexible alteration of the model the model data can be parameterised.
SolidWorks SolidWorks is a 3D-CAD programme.
Unigraphics Unigraphics (NX Siemens) is an interactive CAD/CAM/CAE system. Originally developed by Unigraphics Solutions based on their own Parasolid modelling kernel, the company was taken over by Siemens. Since then, it has operated as Siemens PLM Software, which is developing and distributing the software.
Pro/E Pro/E is a parametric 3D-CAD software, also known as Pro/ENGINEER, Creo Elements/Pro or ProE. The manufacturer of this software is Parametric Technology Corporation (PTC).
CATIA CATIA (Computer Aided Three-Dimensional Interactive Application) is a CAD programme, which was originally developed for aircraft construction, but which has now become established in many branches.
Embedded Software Refers to programs, which run in embedded systems in cars, music systems, telephones, heating systems, household devices, etc. and which the user normally does not notice.
Resident Engineering A system which makes possible the communication between two physically separated, yet cooperating units of an organization. 
Hardware-in-the-Loop
(HiL)
Test scenarios in automotive technology where the components to be tested are integrated in a simulated application environment.
Avionics

All electrical and electronic devices on board of an aircraft, including the flight instruments. 

 
Finite Element Method
(FEM)
A numerical method for solving partial differential equations. This method is widespread in engineering and is the standard tool for solid body simulations. This approach uses approximate solutions to differential equations, whose prediction accuracy can be increased by increasing the degree of freedom and thus the computing effort involved.
Thermographic measurements Recording the module temperature of a photovoltaic installation by means of a thermographic imaging camera in order to identify possible defects (e.g. hotspots).

Measurement technology

D-Sub

D-Sub (often erroneously referred to as Sub-D) is a common type of electrical connector for data connections. 

DIP Switch

Small switch arrays implemented as Dual Inline Package (DIP). DIP switches are mounted on motherboards and serve to adjust configurations as well as to change parameters.

RFID Reader

Radio frequency identification - serves to automatically identify and localize animate and inanimate objects and thus help facilitate data collection (also referred as radio etiquettes)

Matrix Unit

Unit for connecting several test stations of a measurement system using sequential measurement of different endurance test subjects.

Trigger & Timing map

An integral part of every ROTEC measurement system. The map serves as an access point for external trigger systems and at the same time it represents a common time basis for all other measurement maps built in. That way it allows synchronous collection of data via several channels.

TTL Adaptive Electronics

Electronics for the generation and adaptation of a TTL pulse. It serves as a connector between the sensor and the measurement system.

RASRotation Analysis System (measurement tool)
RAS SoftwareMeasurement and analysis tool for RAS
RASFE Front end (data collection unit)
RASnbNotebook or measurement and control unit
RASdlData log

 

 

Energy

EPC Engineering, Procurement and Construction, EPC for short, describes a form of project process familiar in the international construction industry, and in particular in plant construction, and the associated form of contract in which the contractor is designated as the EPC contractor or general contractor.
HVI lightning protection For HVI lightning protection, high-voltage resistant insulated conductors with a voltage-controlled outer sheath are used.
Photovoltaik & PV Photovoltaic (PV for short) means the direct conversion of energy from light, usually sunlight, into electricity by means of solar panels.
Mounting systems A mounting system is a substructure used to mount solar and photovoltaic modules.

Fleet management

InterfaceThe interface is the part of a system which is used for communication.
Smart cardA smart card, often also described as a chip card or Integrated Circuit Card (ICC), is a special plastic card with a built in chip which contains a hardware logic, a memory or even a microprocessor.
Driving dynamicsDriving dynamics is a special area of dynamics and includes the calculation of the route, time, speed, acceleration, expenditure of energy, engine warming, driving forces, performance, resistance to motion, towing capacity and the degree of efficiency of vehicles. The aim of these calculations is to reduce consumption and wear.
Location and trackingBy means of vehicle location and tracking the current position and speed, the distances covered and the time spent not moving can be determined.
Car pool efficiencyAnalysis and decision-making for an ideal car pool mix of combustion engine, hybrid and electric vehicles.
Car pool managementAn overview of car pool data such as vehicle related general inspections, tyre changes and damage management.
Booking a pool carBooking a pool car, also known as car sharing, is the organised shared use of one or more vehicles.
Key managementCentral management of keys in an electronically secured key cupboard.
Driving licence checkA check that the driver is in fact authorised to drive by means of a legally approved RFID label on the driving licence.
Vehicle log bookIn a vehicle log book information on the journeys undertaken using the vehicle, on the driver, on the mileage at the start and end of the journey and on the reason for the journey is recorded. The vehicle log book can also be used as documentary evidence for the police, the tax office or within the company.
