A resolver is similar to a synchro, but has a stator with four leads, the windings being 90 degrees apart physically instead of 120 degrees. Its rotor might be synchro-like, or have two sets of windings 90 degrees apart. Although a pair of resolvers could theoretically operate like a pair of synchros, resolvers are used for computation.
Three goals of plant taxonomy are the identification, classification and description of plants. The distinction between these three goals is important and often overlooked. Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification ...
Plants in the C22 cycle were 50 cm taller had twice the leaf area index, reached anthesis 7 days later and had a 30% higher harvest index than C0 (Table 1) [clarification needed] Differences in growth were detected early in ontogeny. The root growth of C22 exceeded that of C0 and the ratio of shoot dry mass to root dry mass was reduced by ...
Parts of plant stem Euonymus alata, an example of alate stems Saraca cauliflora, an example of cauliflora Sciadopitys verticillata, an example of a verticillate plant. Accessory buds – an embryonic shoot occurring above or to the side of an axillary bud; also known as supernumerary bud. Acrocarpous – produced at the end of a branch.
These plants, normally woody perennials, grow stems into the air, with their resting buds being more than 50 cm above the soil surface, [10] e.g. trees and shrubs, and also epiphytes, which Raunkiær later separated as a distinct class (see below). Raunkiær further divided the phanerophytes according to height as Megaphanerophytes ...
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes , resulting in offspring genetically different from either parent.
An example of synchroscope operation on a hydroelectric generator. Synchroscopes are used in any power plant that connects to an outside electrical grid and also in isolated plants containing more than one generator. Each generator must be synchronized with the others before being connected to the plant bus. If line voltages are unequal when ...
Analogue devices that perform a similar function include the synchro, the resolver, the rotary variable differential transformer (RVDT), and the rotary potentiometer. A linear encoder is similar to a rotary encoder, but measures position or motion in a straight line, rather than rotation. Linear encoders often use incremental encoding and are ...
