Design Rule For Camera File System
Design rule for Camera File system (DCF) is a JEITA specification (number CP-3461) which defines a file system for digital cameras, including the directory structure, file naming method, character set, file format, and metadata format. It is currently the de facto industry standard for digital still cameras. The file format of DCF conforms to the Exif specification, but the DCF specification also allows use of any other file formats. As of 2021 the 2010 version 2.0 of the standard was current. File system In order to guarantee interoperability, DCF specifies the file system for image and sound files to be used on formatted DCF media (like removable or non-removable memory) as FAT12, FAT16, FAT32, or exFAT. Media with a capacity of more than 2 GB must be formatted using FAT32 or exFAT. The DCF standard defines that the " Read Only" file and directory attribute of FAT file systems can be used to protect files or directories from accidental deletion. Other existing attributes ...

Dyneema Composite Fabric
Dyneema Composite Fabric (DCF), also known as Cuben Fiber (CTF3), is a high-performance non-woven composite material used in high-strength, low-weight applications. It is constructed from a thin sheet of ultra-high-molecular-weight polyethylene (UHMWPE, "Dyneema") laminated between two sheets of polyester. It is used in various applications that call for a fabric with high tensile strength, but where low weight is desirable, such as sails and ultralight backpacking equipment. The material was developed by the Cuben Fiber and Cubic Tech Corporations in the 1990s. In 2015, Cubic Tech was acquired by DSM, their supplier for the UHMWPE fiber. The product was subsequently renamed "Dyneema Composite Fabric" ("DCF"), a generic brand name DSM uses for all of their composite products which incorporate UHMWPE. History The name Cuben Fiber was coined by the press in reference to America³ (pronounced ''America Cubed''), the winner of the 1992 America's Cup. During the 1992 Cup, that yach ...

Dorothy Canfield Fisher Children's Book Award
The Vermont Golden Dome Book Award (formerly the Dorothy Canfield Fisher Children's Book Award) annually recognizes one new American children's book selected by the vote of Vermont schoolchildren. It was inaugurated in 1957. The award is co-sponsored by the Vermont State PTA and the Vermont Department of Libraries and was originally named after the Vermont writer Dorothy Canfield Fisher. In 2020, it was temporarily renamed the "VT Middle-Grade Book Award" before schoolchildren voted to officially call it the "Vermont Golden Dome Book Award". Selection process and award Each spring a committee of eight adults selects a "Master List" of thirty books first published during the previous calendar year. The list is announced at the annual Dorothy Canfield Fisher Conference, usually in May, and is available at Vermont school and public libraries for children who wish to participate over the next eleven months. The following spring, those children who have read at least five of the thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Consular Filing
Direct Consular Filing (DCF) is a process related to immigration to the United States whereby Form I-130 (Petition for Alien Relative), I-360 (Petition for Amerasian, Widow(er), or Special Immigrant), or I-600 (Petition to Classify Orphan as an Immediate Relative), is filed with a United States embassy or consulate in another country rather than with the United States Citizenship and Immigration Services lockbox or service center facilities located within the US. The approved form can then be used to obtain an IR or CR visa within the same country. DCF is available only under exceptional circumstances and can only be done in the country where the petitioner (who, in the case of Forms I-130 and I-600, is distinct from the eventual visa ''applicant'') legally resides. Conditions for Direct Consular Filing Official rules The regular application process for people outside the United States who wish an approval for Form I-130, I-360, or I-600 is to submit the application to the USCIS lo ...

Discounted Cash Flow
The discounted cash flow (DCF) analysis is a method in finance of valuing a security, project, company, or asset using the concepts of the time value of money. Discounted cash flow analysis is widely used in investment finance, real estate development, corporate financial management and patent valuation. It was used in industry as early as the 1700s or 1800s, widely discussed in financial economics in the 1960s, and became widely used in U.S. courts in the 1980s and 1990s. Application To apply the method, all future cash flows are estimated and discounted by using cost of capital to give their present values (PVs). The sum of all future cash flows, both incoming and outgoing, is the net present value (NPV), which is taken as the value of the cash flows in question; see aside. For further context see valuation overview; and for the mechanics see valuation using discounted cash flows, which includes modifications typical for startups, private equity and venture capital, co ...

Double-clad Fiber
Double-clad fiber (DCF) is a class of optical fiber with a structure consisting of three layers of optical material instead of the usual two. The inner-most layer is called the ''core''. It is surrounded by the ''inner cladding'', which is surrounded by the ''outer cladding''. The three layers are made of materials with different refractive indices. There are two different kinds of double-clad fibers. The first was developed early in optical fiber history with the purpose of engineering the dispersion of optical fibers. In these fibers, the core carries the majority of the light, and the inner and outer cladding alter the waveguide dispersion of the core-guided signal. The second kind of fiber was developed in the late 1980s for use with high power fiber amplifiers and fiber lasers. In these fibers, the core is doped with active dopant material; it both guides and amplifies the signal light. The inner cladding and core together guide the pump light, which provides the energy ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributed Coordination Function
Distributed coordination function (DCF) is the fundamental medium access control (MAC) technique of the IEEE 802.11-based WLAN standard (including Wi-Fi). DCF employs a carrier-sense multiple access with collision avoidance (CSMA/CA) with the binary exponential backoff algorithm. DCF requires a station wishing to transmit to listen for the channel status for a DIFS interval. If the channel is found busy during the DIFS interval, the station defers its transmission. In a network where a number of stations contend for the wireless medium, if multiple stations sense the channel busy and defer their access, they will also virtually simultaneously find that the channel is released and then try to seize the channel. As a result, collisions may occur. In order to avoid such collisions, DCF also specifies random backoff, which forces a station to defer its access to the channel for an extra period. The length of the backoff period is determined by the following equation: \mathrm = \math ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CANopen
CANopen is a communication protocol and device profile specification for embedded systems used in automation. In terms of the OSI model, CANopen implements the layers above and including the network layer. The CANopen standard consists of an addressing scheme, several small communication protocols and an application layer defined by a device profile. The communication protocols have support for network management, device monitoring and communication between nodes, including a simple transport layer for message segmentation/desegmentation. The lower level protocol implementing the data link and physical layers is usually Controller Area Network (CAN), although devices using some other means of communication (such as Ethernet Powerlink, EtherCAT) can also implement the CANopen device profile. The basic CANopen device and communication profiles are given in the CiA 301 specification released by CAN in Automation. Profiles for more specialized devices are built on top of this basic pro ...
