This species grows to a length of convert 30.0 cm in fish measurement TL . It is closely related to the popular plecostomus catfish kept in many aquarium aquaria as an algae eater, but is immediately distinguished by being dark grey to black and having bright, turquoise coloured eyes. Like other species of the Panaque genus, P. cochliodon feeds primarily on submerged wood http www.towson.edu nelson Panaque manaus.html . Blue eyed plecs grow to about 30 cm in length, and like other Panaque spp., they are clumsy swimmers adapted to staying close the substrate, in particular using the sucker like mouth to hold onto submerged rocks and wood. Blue eye plecs as aquarium fish Blue eyed plecs have been kept as aquarium fish, and were fairly popular during the 1980s and early 1990s. However, they are now very rarely traded because wild fish can only be obtained from rivers in Colombia considered to be outside the control of the Colombian government. http www.planetcatfish.com faq index.php?qid 52 As with other Panaque , these fish are generally hardy and easy to keep, although parasitic, Rickettsia like bacteria can be a problem http www.cdc.gov ncidod eid vol3no2 fryer.htm , particularly when newly imported.

While the royal plec also eats algae, it is best known among biologists as being among the very few fish capable of eating and digesting wood . It does so using symbiotic gut bacteria . Royal plecs are light grey in colour patterned with dark grey squiggles. They have red eyes and the dorsal fins are edged with cream or gold. The body is encased in heavy armour, except for the belly, which is soft. This armour is made of strong plates of skin, not scales. Royal plecs can grow to 43 centimetres 17 in in length. Because they are heavy and inflexible, they do not swim well, but they do have a strong sucker like mouth that enables them to hold onto rocks and wood in fast flowing waters.

P. gibbiceps shows all the characteristic features of its genus a large dorsal fin with more than nine rays, prominent nasal flares and a prominent hump or crest anterior to the dorsal fin as well as a substantial base to the dorsal fin. Adult fish easily attain a length of convert 50.0 cm in fish measurement TL and can live for more than 20 years. A typical plec shape is shown, patternation consists of primarily irregular largish brown spots on a yellowish backgroung giving a honeycombed like appearance, additional pattern features common to related species may be visible on close inspection. As this fish grows the spots get smaller. Like most plecs this species is primarily vegetarian though will eat dead animals. In the wild these fish are found in shoals in sluggish rivers of the Amazon River Amazon and Orinoco river systems, they also occupy flooded land during the wet season. During the dry season P. gibbiceps will aestivate in burrows around 1 metre long dug into mud banks along the length of a river, egg rearing is also presumed to take place in burrow. The species name comes from the Latin gibbus hump and Greek cep head, a reference to the centrally located ridge.

Unreferenced date December 2006 expert subject electronics date June 2010 Electronic design comprises the analysis and synthesis of electronic circuits Methods To design any electrical circuit, either Analogue electronics analog or Digital circuit digital , Electrical engineering electrical engineers need to be able to predict the voltages and currents at all places within the circuit. Linear circuit s, that is, circuits wherein the outputs are linearly dependent on the inputs, can be analyzed by hand using complex analysis . Simple nonlinear circuits can also be analyzed in this way. Specialized software has been created to analyze circuits that are either too complicated or too nonlinear to analyze by hand. Circuit simulation software allows engineers to design circuits more efficiently, reducing the time cost and risk of error involved in building circuit prototypes. Some of these make use of hardware description languages such as VHDL or Verilog . Network simulation software More complex circuits must be analyzed with circuit simulation software such as SPICE and EMTP and many others. Linearization around operating point When faced with a new circuit, the software first tries to find a Steady state steady state solution wherein all the nodes conform to Kirchhoff s Current Law and the voltages across and through each element of the circuit conform to the voltage current equations governing that element. Once the steady state solution is found, the software can analyze the response to perturbations using piecewise approximation, harmonic balance or other methods. Piece wise linear approximation Software such as the PLECS interface to Simulink uses piecewise linear approximation of the equations governing the elements of a circuit. The circuit is treated as a completely linear network of Diode Shockley diode equation ideal diode s. Every time a diode switches from on to off or vice versa, the configuration of the linear network changes. Adding more detail to the ap ... more details

Pleco is a common name for fish from the family Loricariidae . Hypostomus plecostomus known colloquially as a sucker fish is the scientific name for a type of Fresh water freshwater tropical Central America Central and South America n fish belonging to the family biology family Loricariidae . They are large algae eaters, and to differentiate them from small algae eaters, they are often referred to as plecostomus , often abbreviated as plecos or plecs . They are extremely popular in Aquarium aquaria for their ability to clean tanks by eating algae growth and dead fish. In Malaysia , these fish are called ikan bandaraya . Bandaraya in Malay means City. In the capital city of Kuala Lumpur, garbage collection is carried out by the Kuala Lumpur City Hall Dewan Bandaraya Kuala Lumpur or DBKL for short . It is this allusion garbage collection that gives the fish the local nickname Ikan Bandaraya. These friendly natured fish can typically be purchased when about convert 8 cm and may grow up to convert 60 cm if there is adequate room, making them impractical for any but the largest aquaria.
