39-691: MV Viking Star is the lead ship of the Viking Star class of cruise ships , and the first such ship operated by Viking Ocean Cruises , a division of Viking Cruises . She entered service in April 2015. Two Viking Star -class sister ships , Viking Sea and Viking Sky , joined her in the Viking Ocean Cruises fleet in 2016. Viking Star was designed by SMC Design of London with Exterior styling by Clifford Denn Design, while Rottet Studio in Los Angeles

78-633: A mockup , which is an inert representation of a machine's appearance, often made of some non-durable substance. An electronics designer often builds the first prototype from breadboard or stripboard or perfboard , typically using "DIP" packages. However, more and more often the first functional prototype is built on a "prototype PCB " almost identical to the production PCB, as PCB manufacturing prices fall and as many components are not available in DIP packages, but only available in SMT packages optimized for placing on

117-425: A PCB. Builders of military machines and aviation prefer the terms "experimental" and "service test". In electronics , prototyping means building an actual circuit to a theoretical design to verify that it works, and to provide a physical platform for debugging it if it does not. The prototype is often constructed using techniques such as wire wrapping or using a breadboard , stripboard or perfboard , with

156-556: A cruise ship. The smallest staterooms are 25 m (270 sq ft) in size; the two-room suites range from 70.3 m (757 sq ft) to 134.5 m (1,448 sq ft) in area, and feature wrap-around private balconies offering sweeping views. The vessel is fitted with energy-efficient hybrid engines, and onboard solar panels and exhaust pollution-minimising equipment to enable her to meet strict environmental regulations. Her COMPAC propeller shaft bearings, manufactured by Thordon Bearings, are lubricated by seawater, which

195-526: A favorite among US Military modelers), railroad equipment, motor trucks, motorcycles, and space-ships (real-world such as Apollo/Saturn Vs, or the ISS). As of 2014, basic rapid prototype machines (such as 3D printers ) cost about $ 2,000, but larger and more precise machines can cost as much as $ 500,000. In architecture , prototyping refers to either architectural model making (as form of scale modelling ) or as part of aesthetic or material experimentation , such as

234-499: A time to the initial prototype. In many programming languages , a function prototype is the declaration of a subroutine or function (and should not be confused with software prototyping). This term is rather C / C++ -specific; other terms for this notion are signature , type and interface . In prototype-based programming (a form of object-oriented programming ), new objects are produced by cloning existing objects, which are called prototypes. The term may also refer to

273-468: A way that the Planck constant h is prescribed a value of exactly 6.626 070 15 × 10  joule-second (J⋅s) Until 1960, the meter was defined by a platinum-iridium prototype bar with two marks on it (that were, by definition, spaced apart by one meter), the international prototype of the metre , and in 1983 the meter was redefined to be the distance in free space covered by light in 1/299,792,458 of

312-455: A week long period of sea trials in the Aegean Sea, during which she underwent more than 80 different tests. A variety of functions and systems were evaluated, including engine and propulsion performance, the navigation systems, and cabin acoustics. Viking Ocean Cruises took delivery of Viking Star at the shipyard on 28 March 2015. On board, Viking Star features two pools, the main pool and

351-518: Is a form of functional or working prototype. The justification for its creation is usually a data migration , data integration or application implementation project and the raw materials used as input are an instance of all the relevant data which exists at the start of the project. The objectives of data prototyping are to produce: To achieve this, a data architect uses a graphical interface to interactively develop and execute transformation and cleansing rules using raw data. The resultant data

390-513: Is becoming practical to eliminate the creation of a physical prototype (except possibly at greatly reduced scales for promotional purposes), instead modeling all aspects of the final product as a computer model . An example of such a development can be seen in Boeing 787 Dreamliner , in which the first full sized physical realization is made on the series production line. Computer modeling is now being extensively used in automotive design, both for form (in

429-431: Is possible that a prototype may fail to perform acceptably although the production design may have been sound. Conversely, prototypes may perform acceptably but the production design and outcome may prove unsuccessful. In general, it can be expected that individual prototype costs will be substantially greater than the final production costs due to inefficiencies in materials and processes. Prototypes are also used to revise

468-491: Is recycled into the ocean. The use of seawater as a lubricant lowers in-service maintenance costs, by eliminating the requirement for an aft seal. The seawater lubricant also replaces expensive biodegradable oils, which, if used, would need to be stored, sampled and disposed of, and would also create a risk of accidental oil discharge. The theatre features live entertainment, as well as new-release films and some old favourites. Additionally, there are port talks and lectures from

507-410: Is the first of a series or class of ships that are all constructed according to the same general design . The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take five to ten years to build. Improvements based on experience with building and operating the lead ship are likely to be incorporated into the design or construction of later ships in

546-414: Is then evaluated and the rules refined. Beyond the obvious visual checking of the data on-screen by the data architect, the usual evaluation and validation approaches are to use Data profiling software and then to insert the resultant data into a test version of the target application and trial its use. When developing software or digital tools that humans interact with, a prototype is an artifact that

585-490: Is used as the standard of measurement of some physical quantity to base all measurement of that physical quantity against. Sometimes this standard object is called an artifact . In the International System of Units ( SI ), there remains no prototype standard since May 20, 2019 . Before that date, the last prototype used was the international prototype of the kilogram , a solid platinum-iridium cylinder kept at

624-409: Is used to ask and answer a design question. Prototypes provide the means for examining design problems and evaluating solutions. HCI practitioners can employ several different types of prototypes: In the field of scale modeling (which includes model railroading , vehicle modeling, airplane modeling , military modeling, etc.), a prototype is the real-world basis or source for a scale model—such as

663-521: The Adelaide class in Royal Australian Navy service. Prototype A prototype can also mean a typical example of something such as in the use of the derivation ' prototypical '. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes . The word prototype derives from

702-574: The Bureau International des Poids et Mesures (International Bureau of Weights and Measures) in Sèvres France (a suburb of Paris ) that by definition was the mass of exactly one kilogram . Copies of this prototype are fashioned and issued to many nations to represent the national standard of the kilogram and are periodically compared to the Paris prototype. Now the kilogram is redefined in such

741-515: The Forty Wall House open source material prototyping centre in Australia. Architects prototype to test ideas structurally, aesthetically and technically. Whether the prototype works or not is not the primary focus: architectural prototyping is the revelatory process through which the architect gains insight. In the science and practice of metrology , a prototype is a human-made object that

780-585: The Greek πρωτότυπον prototypon , "primitive form", neutral of πρωτότυπος prototypos , "original, primitive", from πρῶτος protos , "first" and τύπος typos , "impression" (originally in the sense of a mark left by a blow, then by a stamp struck by a die (note "typewriter"); by implication a scar or mark; by analogy a shape i.e. a statue, (figuratively) style, or resemblance; a model for imitation or illustrative example—note "typical"). Prototypes explore different aspects of an intended design: In general,

819-524: The Prototype Javascript Framework . Additionally, the term may refer to the prototype design pattern. Continuous learning approaches within organizations or businesses may also use the concept of business or process prototypes through software models. The concept of prototypicality is used to describe how much a website deviates from the expected norm, and leads to a lowering of user preference for that site's design. A data prototype

858-421: The styling and aerodynamics of the vehicle) and in function—especially for improving vehicle crashworthiness and in weight reduction to improve mileage. The most common use of the word prototype is a functional, although experimental, version of a non-military machine (e.g., automobiles, domestic appliances, consumer electronics) whose designers would like to have built by mass production means, as opposed to

897-546: The Infinity Pool, a spa and a fitness center. She also has three restaurants, lounges, the piano lounge and the explorers lounge, the wintergarden, the aquavit terrace and the world cafe. Also, Viking Star has a sports deck, the star theatre and bar, the lobby bar and various shops. Viking Star has five stateroom categories, all with private verandas, and 14 Explorer Suites. Up to 930 passengers can be accommodated in her 465 staterooms and suites, all of which are spacious for

936-434: The class, so it is rare to have vessels that are identical. The second and later ships are often started before the first one is completed, launched and tested. Nevertheless, building copies is still more efficient and cost effective than building prototypes , and the lead ship will usually be followed by copies with some improvements rather than radically different versions. The improvements will sometimes be retrofitted to

975-404: The creation of prototypes will differ from creation of the final product in some fundamental ways: Engineers and prototype specialists attempt to minimize the impact of these differences on the intended role for the prototype. For example, if a visual prototype is not able to use the same materials as the final product, they will attempt to substitute materials with properties that closely simulate

1014-407: The cycle returns to customer evaluation. The cycle starts by listening to the user, followed by building or revising a mock-up, and letting the user test the mock-up , then back. There is now a new generation of tools called Application Simulation Software which help quickly simulate application before their development. Extreme programming uses iterative design to gradually add one feature at

1053-403: The design for the purposes of reducing costs through optimization and refinement. It is possible to use prototype testing to reduce the risk that a design may not perform as intended, however prototypes generally cannot eliminate all risk. Building the full design is often expensive and can be time-consuming, especially when repeated several times—building the full design, figuring out what

1092-508: The full design. In technology research, a technology demonstrator is a prototype serving as proof-of-concept and demonstration model for a new technology or future product, proving its viability and illustrating conceivable applications. In large development projects, a testbed is a platform and prototype development environment for rigorous experimentation and testing of new technologies, components, scientific theories and computational tools. With recent advances in computer modeling it

1131-437: The intended final materials. Engineers and prototyping specialists seek to understand the limitations of prototypes to exactly simulate the characteristics of their intended design. Prototypes represent some compromise from the final production design. This is due to the skill and choices of the designer(s), and the inevitable inherent limitations of a prototype. Due to differences in materials, processes and design fidelity, it

1170-488: The lead ship. Occasionally, the lead ship will be launched and commissioned for shakedown testing before following ships are completed, making the lead ship a combination of template and prototype, rather than expending resources on a prototype that will never see actual use. Ship classes are typically named in one of two ways; echoing the name of the lead ship, such as the Pennsylvania -class battleships , whose lead ship

1209-503: The on-board cultural enrichment programmes on art, history and culture. The lecture programme includes academic lecturers, local speakers and interactive demonstrations. On 12 October 2016, a mast on Viking Star clipped the underside of the Cape Cod Canal Railroad Bridge . Subsequent inspection of the bridge indicated no damage, other than scraped paint. Lead ship The lead ship , name ship , or class leader

1248-429: The problems are and how to solve them, then building another full design. As an alternative, rapid prototyping or rapid application development techniques are used for the initial prototypes, which implement part, but not all, of the complete design. This allows designers and manufacturers to rapidly and inexpensively test the parts of the design that are most likely to have problems, solve those problems, and then build

1287-411: The prototyping platform, or replace it with only the microcontroller chip and the circuitry that is relevant to their product. Prototype software is often referred to as alpha grade , meaning it is the first version to run. Often only a few functions are implemented, the primary focus of the alpha is to have a functional base code on to which features may be added. Once alpha grade software has most of

1326-438: The real EMD GP38-2 locomotive—which is the prototype of Athearn 's (among other manufacturers) locomotive model. Technically, any non-living object can serve as a prototype for a model, including structures, equipment, and appliances, and so on, but generally prototypes have come to mean full-size real-world vehicles including automobiles (the prototype 1957 Chevy has spawned many models), military equipment (such as M4 Shermans,

1365-463: The required features integrated into it, it becomes beta software for testing of the entire software and to adjust the program to respond correctly during situations unforeseen during development. Often the end users may not be able to provide a complete set of application objectives, detailed input, processing, or output requirements in the initial stage. After the user evaluation, another prototype will be built based on feedback from users, and again

1404-459: The result being a circuit that is electrically identical to the design but not physically identical to the final product. Open-source tools like Fritzing exist to document electronic prototypes (especially the breadboard-based ones) and move toward physical production. Prototyping platforms such as Arduino also simplify the task of programming and interacting with a microcontroller . The developer can choose to deploy their invention as-is using

1443-613: Was USS  Pennsylvania , and the Olympic class , whose lead ship was RMS  Olympic , or defining a theme by which vessels in the class are named, as in the Royal Navy 's Tribal-class frigates , named after tribes of the world, such as HMS  Mohawk . If a ship class is produced for another navy, the first active unit will become the lead ship for that navy; for example, the Oliver Hazard Perry -class frigates are known as

1482-575: Was cut on 7 June 2013 at the Fincantieri Marghera shipyard in Marghera , Italy. The plate cutting ceremony was attended, among others, by Torstein Hagen , founder and chairman of Viking. The keel was laid on 18 December 2013. Fincantieri launched Viking Star on 23 June 2014, about 20 days earlier than the previously announced launch date in mid-July. In mid-December 2014, the ship successfully completed

1521-493: Was engaged to design her interior. The vessel's modern Scandinavian design ties in with that of Viking Cruises' river cruisers, and was intended to mix onboard elegance with a focus on destinations. As a relatively small vessel, Viking Star is able to access most ports directly, and thus facilitate efficient and trouble-free embarkation and debarkation processes. She also has a hydro-dynamically optimised streamlined hull and bow for maximum fuel efficiency. The ship's first plate
