N2 - APROS is a multifunctional simulator, suitable for various tasks throughout the complete power plant life cycle from design to operator training. APROS is widely used for dynamic studies in light water nuclear reactor technology. Currently the simulation capabilities of the code are being developed for evaluation of Generation IV nuclear reactor designs that use liquid metals e.

However, validation of APROS code has been limited to light water cooled systems test facilities and reactors. Therefore validation is required for the LBE thermal-hydraulic models. Uncertainty analysis was employed in the validation process. Results of quantitative code validation are presented in the paper.

Suggestions for improvements of the validation methodology, experimental conditions and approaches to reduction of experimental uncertainty are discussed in detail.

The majority of the current version of this specification is dedicated to describing how to use WebVTT files for captioning or subtitling. There is minimal information about chapters and time-aligned metadata and nothing about video descriptions at this stage.

The main use for WebVTT files is captioning or subtitling video content. Here is a sample file that captions an interview:. You can see that a WebVTT file in general consists of a sequence of text segments associated with a time-interval, called a cue definition.

Beyond captioning and subtitling, WebVTT can be used for time-aligned metadata, typically in use for delivering name-value pairs in cues.It is a time-indexed file format and it is referenced by HTML5 video and audio elements.

As with many assistive technologies, it would be a mistake to assume that they are only meant as a way to provide for accessibility accomodations. We can enable captions when the ambient noise is too loud to listen to a recorded presentation, we can use chapters to navigate through a long lecture video just like DVD or Blue Ray movies.

Captions can also improve our movies' discoverability. Google indexes the content of our captions. Both YouTube and Google search can report results based on the video captions available for a given file.

WebVTT files provide open captions, independent of the audio or video files they are attached to, they are not "hard coded" into pixels. This also means that creating VTT files requires nothing more than a text editor; although there are more specialized tools to create the captions.

VTT Concepts

Based on Silvia Pfeiffer's post to the VTT community group dated August,and updated with new information about Firefox, the following browsers support VTT tracks for video and audio:. Playr seems to be the most feature complete polyfill for HTML5 video tracks. The downside is 2 more files one CSS and one JavaScript to download for the video page but until VTT is widely supported the extra files are worth the effort to create accessible content. One way to ensure that we only load our polyfill if the browser doesn't support tracks natively is to use Modernizr.

The code below uses plain JavaScript to test if a browser supports HTML5 video by creating an empty video element and testing for the video's canPlayType property. It will not load the code for a polyfill like the Modernizr example.

The example below makes the following assumptions:. Also note that we're testing for specific audio and video codec combinations. WebM supports a single combination of video and audio codecs but MP4 supports multiple profiles, not all of which are supported in HTML5 video. Playr is by no means the only polyfil or the only player that supports VTT. It is the one that I found the most feature complete for what I needed.

The selection below represents a set of players and polyfills available. The simplest and most often used type of text track, captions provide alternative text content for people with visual dissabilities, for people who choose to play the video without audio, and others.

Depending on the player you may have open captions, where the captions are always visible on screen, or closed captions where you have to manually activate the display of captions; Either open or closed, the captions are independent of the content they are attached to.

Subtitle Tracks are similar to Caption Tracks but are not meant to address accessibility issues as Captions are. Subtitle tracks are used primarily to convey the dialogue in a language other than the one being spoken in the video.Address :. Local CSS file :. CSS or cascading style sheet is a web based application language which describes the presentation and style from the document that is written in a markup language.

These are the languages commonly utilized in custom web style and documentation. These languages are used to format the content material from the web sites. CSS is used for style and designing from the internet pages.

the new code

W3C or world wide web consortium is a well-known standard which maintains this language. The purpose behind introducing this language would be to present the different aspects and content of web page in presentable and sequence order. W3C CSS based web application development has numerous benefits. It's also useful for the typical customers.

Sometimes some websites take a lengthy to open. This only irritates the visitor and he browses to some other website from where he can access info with out any delay. This decreases the volume of visitors on your website. W3C CSS takes care of this issue. It also provides an attractive visual display. Another feature is that CSS created web pages are displayed in the same manner when these pages are viewed after downloading.

CSS is quite simple to discover from the regular open supply web sites. W3C also provides all the guide notes for the assist of designers once they use CSS language in the content setting of their web pages. The pages designed in CSS may be displayed in any kind of device like hand held internet device and mobile phones. They load effortlessly because of their little size.

Therefore, a website designed utilizing CSS loads easily on all devices also. It provides a wide range of features and is convenient to use.

Actually, CSS is one of the best option for custom website designing accessible these days. Therefore, you should hire only an expert and reliable custom internet design company for the web site.

The learning curve is fairly steep, simply because hinting requires professional skills regardless of the tools. Even accomplished type designers who have been using font editors for years to design fonts have evaluated VTT and decided that professional hinting is not for them.
