| Document management system + | 1. A document management system (DMS) refers to the management of digitized or digital documents via a database. The goal is a paperless office., The user has the possibility to search for documents using a software application or a pure web interface. Although these are available in a file system, the database of the DMS contains indexed search hits., 2. A document management system (DMS) is a system (based on computer programs in the case of the management of digital documents) used to track, manage and store documents and reduce paper. Most are capable of keeping a record of the various versions created and modified by different users (history tracking). The term has some overlap with the concepts of content management systems. It is often viewed as a component of enterprise content management (ECM) systems and related to digital asset management, document imaging, workflow systems and records management systems. |
| Double Precision + | 1. That is a floating-point number with more precision than a single-precision number. A double-precision number uses twice as many bits as a regular floating-point number. For example, if a single-precision number requires 32 bits, its double-precision counterpart will be 64 bits long. The extra bits increase not only the precision but also the range of magnitudes that can be represented. Most computers use a standard format known as the IEEE., 2. Double-precision floating-point format is a computer number format that occupies 8 bytes (64 bits) in computer memory and represents a wide, dynamic range of values by using a floating point. It usually refers to binary64, as specified by the IEEE 754 standard, not to the 64-bit decimal format decimal64. |
| Dye-Sensitized Solar Cells + | 1. Dye-sensitized solar cells are based on a semiconductor designed such that the nanoparticles of titanium dioxide are coated in a light-sensitive dye and surrounded by electrolyte, which is sandwiched between another electrolyte and a cathode. The anode is a transparent material for the light to pass through. Titanium oxide is in the form of a mesh of particles suspended between the two electrodes. The light-sensitive dye is responsible for converting photons into electrons. The electrolyte is usually an iodide ion that helps in the transfer of electrons to cathode and vice versa. Energy obtained through this simple dye-sensitive cell can be harvested in driving electrical system loads., 2. Dye-sensitized solar cells (DSSCs) use an organic dye to absorb incoming sunlight to produce excited electrons and create an energy which is then transferred to an inexpensive material, such as titanium dioxide (TiO2). From there, the energy is collected on a transparent conducting surface. Currently, its conversion efficiency is between 8% and 11% (limited by the problems associated with both the electrolyte solution and the dye used), which is lower than most of other current solar technology. |

| Electrical conductor + | 1. The conductor is a type of material that allows the flow of an electrical current in one or more directions. Materials made of metal are common electrical conductors. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases., 2. An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat. |
| Electrical grid + | 1. An electrical grid is an interconnected network for delivering electricity from suppliers to consumers. |
| Electrical insulator + | 1. An electrical insulator is a material whose internal electric charges do not flow freely, very little electric current will flow through it under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily. The property that distinguishes an insulator is its resistivity, insulators have higher resistivity than semiconductors or conductors., 2. This is a materialof such low conductivity that electricity cannot go through. Insulating material, oftenglass or porcelain, in a unit form designed so as to support a charged conductor and electrically isolateit. |

| Electroluminescence + | 1. Electroluminescence (EL) is an optical phenomenon and electrical phenomenon in which a material emits light in response to the passage of an electric current or to a strong electric field. This is distinct from black bodylight emission resulting from heat , from a chemical reaction, sound, or other mechanical action., 2. Electroluminescence (EL) imaging takes advantages of the radiadive inter-band recombination of excited charge carriers in solar cells. For electroluminescence investigation the module is operated as a light emitting diode and the emitted radiation due to recombination effects can be detected with a sensitive Si-CCDs camera. For electroluminescence images, the solar cells are supplied, via their metal contacts, with a defined external excitation current while the camera takes an image of the emitted photons at wavelength > 850 nm. Since EL is a low light source, a dark environment is necessary in order to decrease the background noise during the measure. Damaged areas of a solar module appear dark or shine less than good areas. Electroluminescence imaging can be used to detect a multitude of defects in crystalline silicon solar cells, furthermore EL technique provide images with very high resolution that enable to resolve details lesser in size than IR-images that should be hardly perceptible to the eye, such as: micro cracks, bad finger contacts, Crystallization faults in cell material. |
| Electromagnetic compatibility + | 1. Electromagnetic compatibility (EMC) refers to the ability of electrotechnical devices to operate satisfactorily without disturbing or disturbing other devices., 2. Electromagnetic compatibility (EMC) refers to the ability of a technical device not to interfere with other devices by unwanted electrical or electromagnetic effects or to be interfered with by other devices. |
| Emmision + | 1. Emissions are waste from production, distribution and consumption, which are distributed to environmental media. Emmision is often restricted to pollutants., 2. Emissions generally means discharge of any interference in the environment. The source is called the issuer. Each emission causes an immission. |
| Energy Carrier + | An energy carrier is a substance or sometimes a phenomenon that contains energy that can be later converted to other forms such as mechanical work or heat or to operate chemical or physical processes., An energy carrier does not produce energy; it simply contains energy imbued by another system. |

| Extensible Markup Language + | 1. In computing, Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The W3C's XML 1.0 Specification and several other related specifications all of them free open standards define XML., The design goals of XML emphasize simplicity, generality, and usability across the Internet.It is a textual data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, the language is widely used for the representation of arbitrary data structures such as those used in web services., 2. XML, in full extensible markup language, a document formatting language used for some World Wide Web pages. XML began to be developed in the 1990s because HTML (hypertext markup language), the basic format for Web pages, does not allow the definition of new text elements; that is, it is not extensible. XML is a simplified form of SGML (standard generalized markup language) intended for do are published on the Web. |

| File Header + | 1. In information technology, header refers to supplemental data placed at the beginning of a block of data being stored or transmitted. In data transmission, the data following the header are sometimes called the payload or body. It is vital that header composition follows a clear and unambiguous specification or format, to allow for parsing., 2. In a computer file, a header may be a field that precedes the main file content and describes the length of the content or other characteristics of the file. |
| Fill Factor + | 1. The Fill Factor (FF) is essentially a measure of quality of the solar cell. It is calculated by comparing the maximum power to the theoretical power that would be output at both the open circuit voltage and short circuit current together., 2. The "fill factor", more commonly known by its abbreviation "FF", is a parameter which, in conjunction with Voc and Isc, determines the maximum power from a solar cell.
