Limit superior and limit inferior From Wikipedia, the free encyclopedia Jump to navigation Jump to search "Lower limit" and "upper limit" redirect here. In mathematicsthe limit inferior and limit superior of a sequence can be thought of as limiting i.
Any other secondary navigational element may be placed at the bottom of the page if really needed. It is important the users should be able to see page content once the page has loaded without scrolling see 5.
Scrolling a page when there are many links on it can be very cumbersome, as the scrolling action on many mobile devices selects each link in turn. On the other hand, each retrieval of a navigation page takes time and adds cost, so the number of links on a page should not be minimized at the expense of adding page retrievals.
Design the service so that frequently accessed information is easily reached with a minimum number of page retrievals. Navigation to less frequently accessed information may take more retrievals as a result.
A guideline is that users become frustrated if it takes more than four retrievals to reach their objective. Whether this can be achieved depends on the nature of the site and, in particular, how items in menus group together to provide understandable themes. Users of devices that do not have pointing devices have to scroll between hyperlinks using the keypad.
Intelligent grouping, perhaps optimized through adaptation according to usage patterns, can assist usability. At each target of the drill-down navigation an "up" link should be provided to allow the user to jump up an entire section.
Provide the same access key for links that are repeated across pages such as links to the home page. Test for the presence of the accesskey attribute. Verify the presence of the accesskey attribute on links such as the home page.
It is important to identify where a link leads so users can make an assessment of whether following it will be of interest to them. While it is unlikely that the cost in monetary terms of a particular user following a particular link can be specified, it should be possible to give an idea of the size of the resource in bytes or in an abstract way, e.
Links to content that is in a different format or different language to that of the page the link is on i. However, bear in mind that some devices support the rendering of those formats by other applications once downloaded e.
Dear Twitpic Community - thank you for all the wonderful photos you have taken over the years. We have now placed Twitpic in an archived state. Oct 10, · Official answer from veritas: Solution: E. If you know two sides of a triangle, the maximum area of the triangle can be obtained by setting these two sides as the base and height of a right triangle. Returns the base 10 logarithm of a double value. Special cases: If the argument is NaN or less than zero, then the result is NaN. If the argument is positive infinity, then the result is positive infinity.
Additionally, users may wish to download content for later transfer to other devices altogether. So even if it is known that the user agent does not support a particular content type, that content should still be made available.
Identify the implications of following a link if the target is notably large and the user might not anticipate this from the context.
Check for proper descriptions e. Check for links to non-HTML formats. If present check whether there is information about the format of the target of the link. Up, down, left, right and enter are available on most mobile devices, even if there is no pointing device.
This is usually sufficient to allow navigation of the active regions of client-side image maps where they are defined as geometric shapes. Many mobile devices lack a pointing device and server-side image maps cannot be used on such devices.
For the Default Delivery Contextor if a satisfactory image map cannot be displayed, use a list of links with descriptive text instead. Send a request to the site with a device that does not support client-side image maps and check the map element is not present.
Instead, configure the server to perform redirects by means of HTTP 3xx codes. Some mobile devices use a separate window for input; this section does not refer to such windows.
Many mobile devices cannot support more than one window and consequently, attempting to open one will have unpredictable results. Auto-refreshing pages are widely recognized as presenting accessibility problems.
In a mobile environment they may expose the user to undue cost as a result of such a page being left open or put unnoticed into the background.
If an auto-refreshing page is demanded by the application, always provide a means of ceasing the refresh and always inform the user that the page will refresh and may expose them to higher usage costs.
While redirection is a commonly employed mechanism, it must be remembered that redirection usually requires a round-trip to the browser. This adds to delay on slow links; so use a maximum of one redirect per page and limit the number of pages that are redirected.
If auto-refresh is used, check that options are provided to stop any page using auto-refresh. This may add significantly to the load time of the page in the mobile context.
Count the number of linked images, style sheets and other linked items. Review whether a similar effect could be obtained using fewer links. It concentrates on design, the language used in its text and the spatial relationship between constituent components.
It does not address the technical aspects of how the delivered content is constructed, which is discussed in 5.Sin and Salvation, Confession and Forgiveness: Questions and answers about the nature of sin, its consequences, its relationship to salvation and the Christian life thereafter.
Returns the base 10 logarithm of a double value. Special cases: If the argument is NaN or less than zero, then the result is NaN. If the argument is positive infinity, then the result is positive infinity. There is no single Buddhist view concerning abortion. Some traditional sources, including some Buddhist monastic codes, hold that life begins at conception, and that abortion, which would then involve the deliberate destruction of life, should be rejected.
Complicating the issue is the Buddhist belief that "life is a continuum with no discernible starting point". No sin is too great or too awful for God to forgive. No person is so deep in sin, so ingrained in a wicked lifestyle, or so steeped in evil that he or she cannot be saved.
Is there a limit to God's forgiveness? Nothing is beyond God’s forgiveness. No sin is too great or too awful for God to forgive.
No person is so deep in sin, so. UN News produces daily news content in Arabic, Chinese, English, French, Kiswahili, Portuguese, Russian and Spanish, and weekly programmes in Hindi, Urdu and Bangla.
