Concentrator photovoltaic (CPV) systems use large area optical components to collect direct sunlight and transfer the energy onto small, high-efficiency photovoltaic (PV) cells., 2. As generally used, a concentrator is a device that acts as an efficient forwarder of data transmission signals. A remote access hub is sometimes referred to as a concentrator. The term aggregator is also frequently used with approximately the same meaning. A typical concentrator or remote access hub is a device that handles incoming dial-up calls for an Internet (or other network) point-of-presence and performs other services. A concentrator or hub may be able to handle up to 100 dial-up modem calls, support a certain number of ISDN connections, and support leased line and frame relay traffic while also functioning as a router. |

Continous Data + | 1. Continous Data is the opposite of Discrete Data. The data that can take any value within a range. For example: People's heights could be any value within the range of human heights, not just certain fixed heights., 2. This data is called continuous because the scale of measurement has meaning at all points between the numbers given. Continuous data can be shown on a number line, and all points on the line have meaning and are different, but with discrete data only certain values have meaning. |
Cooperative Software Development + | The goal of cooperative software development is to support communication, coordination and cooperation during the development process in order to continuously improve the quality of the product and the process. |
Coordinate Reference System + | 1. CRS provide a standardized way of describing locations. Many different CRSs are used to describe geographic data. The CRS that is chosen depends on when the data was collected, the geographic extent of the data, the purpose of the data, etc., 2. A Coordinate reference system defines, with the help of coordinates, how the two-dimensional, projected map is related to real locations on the earth. With the help of coordinate reference systems every place on the earth can be specified by a set of three numbers, called coordinates. In general CRS can be divided into projected coordinate reference systems (also called Cartesian or rectangular coordinate reference systems) and geographic coordinate reference systems. |
Copyleft + | 1. Copyleft (a play on the word copyright) is the practice of offering people the right to freely distribute copies and modified versions of a work with the stipulation that the same rights be preserved in derivative works down the line. Copyleft software licenses are considered protective or reciprocal, as contrasted with permissive free software licenses., 2. Copyleft is a strategy of utilizing copyright law to pursue the policy goal of fostering and encouraging the equal and inalienable right to copy, share, modify and improve creative works of authorship |
Copyrigh + | 1. Copyright in the Federal Republic of Germany has the task to ensure that the person who has provided his own creative energy for the creation of a work is also appropriately involved in the economic benefits derived from it., 2. Copyright is a legal right created by the law of a country that grants the creator of an original work exclusive rights for its use and distribution. This is usually only for a limited time. The exclusive rights are not absolute but limited by limitations and exceptions to copyright law, including fair use. A major limitation on copyright is that copyright protects only the original expression of ideas, and not the underlying ideas themselves. |
Country codes + | 1. Country codes are short alphabetic or numeric geographical codes (geocodes) developed to represent countries and dependent areas, for use in data processing and communications. Several different systems have been developed to do this. The best known of these is ISO 3166-1, 2. Other well known country codes are IOC country code and FIFA country code. |
Crystalline silicon + | 1. Crystalline silicon (c-Si) is the crystalline forms of silicon, either multicrystalline silicon (multi-Si) consisting of small crystals, or monocrystalline silicon (mono-Si), a continuous crystal. Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells. These cells are assembled into solar panels as part of a photovoltaic system to generate solar power from sunlight., 2. Crystalline silicon (c-Si) is the crystalline forms of silicon. The type of Crystalline Silicon (c-Si) are: Monocrystalline Silicon Solar Cells (mono-Si); Polycrystalline Silicon Solar Cells (p-Si) or multi-crystalline silicon (multi-Si), or Thin-Film Solar Cell (TFSC) or Thin-Film Photovoltaic Cells (TFPV). |
Current-Voltage-curve + | 1. A graphical presentation of the current versus the voltage from a photovoltaic device as the load is increased from the short circuit (no load) condition to the open circuit (maximum voltage) condition. The shape of the curve characterized cell performance., 2. IV curve or Current-Voltage curve of a solar cell/panel shows the possible combinations of current and voltage output of a photovoltaic (PV) device. It is a graph that plots the current versus the voltage from the PV device as the electrical load (or resistance) is increased from short circuit (no load) to open circuit (maximum voltage). The shape of the curve characterizing cell performance. Three important points on the I-V curve are the open-circuit voltage (Voc), short-circuit current (Isc), and peak or maximum power (operating) point (Pmpp). |
Cycle Life + | 1. Cycle Life (number for a specific DOD) – The number of discharge-charge cycles the battery can experience before it fails to meet specific performance criteria. Cycle life is estimated for specific charge and discharge conditions. The actual operating life of the battery is affected by the rate and depth of cycles and by other conditions such as temperature and humidity. The higher the DOD, the lower the cycle life., 2. It is the process of charging a rechargeable battery and discharging it as required into a load. The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time. Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge"., 3.The cycle life is the number of complete charge/discharge cycles that the battery is able to support before that its capacity falls under 80% of it's original capacity |

Dark current + | 1. Dark current is the relatively small electric current that flows through photosensitive devices such as a photomultiplier tube, photodiode, or charge-coupled device even when no photons are entering the device; it consists of the charges generated in the detector through heat,when no outside radiation is entering the detector .Dark current is due to the random generation of electrons and holes within the depletion region of the device., 2. Dark current is unwanted current or signal in a photodetector in the absence of incident light, resulting from thermally excited electrons or leakage of current along the current path |
Data Cloud - Cosmics Leaving Outdoor Droplets + | 2. loud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications., In cloud computing, the word cloud (also phrased as "the cloud") is used as a metaphor for "the Internet," so the phrase cloud computing means "a type of Internet-based computing," where different services — such as servers, storage and applications — are delivered to an organization's computers and devices through the Internet. |
