Image SinusRhythmLabels.svg right thumb Schematic representation of normal Electrocardiography ECG In electrocardiography , the ST segment connects the QRS complex and the T wave and has a duration of 0.08 to 0.12 sec 80 to 120 ms . It starts at the J point junction between the QRS complex and ST segment and ends at the beginning of the T wave. However, since it is usually difficult to determine exactly where the ST segment ends and the T wave begins, the relationship between the RT segment and T wave should be examined together. The typical ST segment duration is usually around 0.08 sec 80 ms . It should be essentially level with the PR and TP segment. The ST segment represents the period when the ventricles are depolarized. It is isoelectric. Interpretation The normal ST segment has a slight upward concavity. Flat, downsloping, or depressed ST segments may indicate coronary ischemia .

In linguistics specifically, phonetics and phonology , the term segment is any discrete unit that can be identified, either physically or auditorily, in the stream of speech. ref A Dictionary of Linguistics & Phonetics , David Crystal, 2003, pp. 408 409 ref Classifying speech units Segments are called discrete because they are separate and individual, such as consonant s and vowel s, and occur in a distinct temporal order. Other units, such as tone linguistics tone , stress linguistics stress , and sometimes secondary articulation s such as nasalization , may coexist with multiple segments and cannot be discretely ordered with them. These elements are termed Prosody linguistics suprasegmental . Kinds of segment The segments of sign language are visual, such as hands, movements, face, and body. They occur in a distinct spatial and temporal order. The SignWriting script represents the spatial order of the segments with a spatial cluster of grapheme s. Other notations for sign language use a temporal order that implies a spatial order. In phonetics , the smallest perceptible segment is a Phone phonetics phone . In phonology , there is a subfield of segmental phonology that deals with the analysis of speech into phoneme s or segmental phonemes , which correspond fairly well to phonetic segments of the analysed speech. Marginal segments When analyzing the inventory of segmental units in any given language , some segments will be found to be marginal, in the sense that they are only found in onomatopoeic words, interjection s, loan word s, or a very limited number of ordinary words, but not throughout the language.

Structure Diamond segments consist of small size diamond s and metal bond materials. The metal bond materials may include the powders of Cu, Sn, Fe, Ag, Co, Ni, WC, Mo, graphite, etc. The diamonds are mixed with the bond materials, and the mixture is loaded into molds. After hot pressing or cold pressing, sintering, and arc grinding, diamond segments are formed.

It works by queuing up large buffer computer science buffer s and letting the network interface card NIC split them into separate packets. The technique is also called TCP segmentation offload TSO when applied to Transmission Control Protocol TCP , or generic segmentation offload GSO . The inbound counterpart of large segment offload is large receive offload large receive offload LRO . Operation When large chunks of data are to be sent over a computer network, they need to be first broken down to smaller segments that can pass through all the network elements like routers and switches between the source and destination computers. This process is referred to as Packet segmentation segmentation . Segmentation is often done by the TCP protocol in the host computer. Offloading this work to the NIC is called TCP segmentation offload TSO . For example, a unit of 64KB 65,536 bytes of data is usually segmented to 46 segments of 1448 bytes each before it is sent over the network through the NIC. With some intelligence in the NIC, the host CPU can hand over the 64 KB of data to the NIC in a single transmit request, the NIC can break that data down into smaller ... according to a template provided by the host s TCP IP stack to each segment, and send the resulting frames over the network.
