  About PDO   (Site not responding. Last check: 2007-10-09)
PDO also finds, develops and operates natural-gas fields and their associated production systems—all on behalf of the Government of Oman.
As part of its gas-production operations, PDO also supplies some 50,000 barrels per day of condensate (liquid hydrocarbons that condense out of natural gas) and about 200 tonnes per day of liquefied petroleum gas, which is chiefly used for cooking.
PDO believes that the sustainable development of the country is furthered through its education and training initiatives and through its efforts to stimulate successful Omani businesses throughout the country.

 The Pacific Decadal Oscillation
PDO indices have been constructed by projecting the observed monthly patterns of North Pacific SST and SLP anomalies onto the characteristic SST and SLP patterns shown in Figures 1 and 2, respectively (Trenberth 1990, Trenberth and Hurrell 1994, Zhang et al.
Figure 4: (top) Characteristic warm-phase PDO October-March air temperature anomalies, in degrees C. This field is based on linear regressions between the gridded surface air temperature data and the SST-based PDO index, shown in the top panel of Figure 3, for the period 1900-1993.
This is true because of the PDO's strong tendency for multi-season and multi-year persistence.

 Pacific Decadal Oscillation: PDO Index   (Site not responding. Last check: 2007-10-09)
The PDO is often quantified by the use of an index, referred to as the PDO Index.
The PDO Index is calculated by spatially averaging the monthly sea surface temperature (SST) of the Pacific Ocean north of 20°N. The global average anomaly is then subtracted to account for global warming (Mantua, 2000).
When the PDO Index is positive, waters in the north central Pacific Ocean tend to be cool, and waters along the west coast of North America tend to be warm.

 What is the Pacific Decadal Oscillation (PDO) and should we be concerned?
When the PDO is in the cold phase…meaning surface layer water temperatures are colder than normal over a large area of the Pacific…La Nina events predominate.
The PDO was in the cold phase from 1947 to 1976…and La Nina events dominated.
Average rainfall at Brownsville during the cold phase of the PDO is 24.07 inches … and 29.79 inches during the warm phase.

 NASA - Moody Pacific Unleashes Another Climate Mystery
Recently, unusual atmospheric conditions, not consistent with the PDO or other phenomenon, have been observed in the North Pacific, leading some scientists to believe the ocean's full fury is still being underestimated, as it might possess another "climate-controller" in its arsenal.
While the PDO is a longer-term natural oscillation going on in the Pacific, its flip from warm to cool provides a new background on which smaller events like El Nino and La Nino occur.
For instance, the warm or positive phase of the PDO can enhance an El Nino episode, amplifying the effects of this warm pool of water on the western U.S. This pattern predominated from the mid-1970s through at least the late 1990s and was a period of more frequent and stronger editions of El Nino.

 Climate Impacts Group   (Site not responding. Last check: 2007-10-09)
The PDO is described as being in one of two phases: a warm phase and a cool phase.
The cool phases for PDO and ENSO, which are not shown, have the opposite patterns of SST anomalies: cool along the equator and the coast of North America and warm in the central north Pacific.
Studies indicate that the PDO was in a cool phase from approximately 1890 to 1925 and 1945 to 1977.

 Albuquerque
Although it is yet to be proven, it appears the negative (cold) side of the PDO cycle leads to increased frequency of La Niña episodes, and possibly enhances the impacts or affects of La Niña.
For winters in which the PDO was categorized as positive or negative, there was very little difference in whether or not the PDO was positive or negative (for winter1 years).
Average precipitation for the negative PDO years was 4.34 inches, 127 percent of normal, representing a surplus of nearly an inch.

 Global Warming FAQ - Alaskan Warming and Pacific Decadal Oscillation (PDO)
Media reports have described alarming levels of Alaskan warming over the past 30 years, but critics have responded that the level of warming is lower than that reported, and that warming over this period is largely a result of a change in the PDO, which resulted in a 'step change' in temperatures around 1976.
This was compared with the PDO Index provided by Nathan Mantua at the University of Washington.
The PDO index was regressed vs the FANB, and the resultant regression formula used to computed 'predicted' FANB temperatures given the PDO index for each year.

If you're using the PDO ODBC driver and your ODBC libraries support ODBC Connection Pooling (unixODBC and Windows are two that do; there may be more), then it's recommended that you don't use persistent PDO connections, and instead leave the connection caching to the ODBC Connection Pooling layer.
This is a safety measure to help avoid inconsistency in the cases where the script terminates unexpectedly--if you didn't explicitly commit the transaction, then it is assumed that something went awry, so the rollback is performed for the safety of your data.

 Portable Distributed Objects - Wikipedia, the free encyclopedia
At the time PDO was one of a number of distributed object systems, which was, for a time in the early 1990s, the "next big thing" in programming.
PDO on the other hand relied on a small number of features in the Objective C runtime to handle both portability as well as distribution.
PDO continues to be used by Mac OS X programmers as a method for interprocess and interapplication communication, and communication between networked applications that only need compatibility with other Mac OS X applications.

 PDO Models   (Site not responding. Last check: 2007-10-09)
As an example, for loop optimizations, PDO makes a prediction about the profit of a data locality optimization by estimating whether data cache misses are increased or decreased.
That is, PDO needs to only predict the profit trend accurately, rather than the absolute profit.
This planner uses PDO to decide whether to apply a single optimization in a given code context.

Automation is another way of reducing costs and PDO is gradually moving away from manual data collection, where people are required to visit individual well heads to read and record data collection and measuring devices, to automated wireless technology.
Abdulsattar concludes, "In all of this talk of technology we must not forget the sound, basic practices which need to be employed at PDO to produce a solid platform for the implementation of all these new, added-value technologies.
In the search for improvement we must also look further afield, and PDO is today examining technologies from other sources to examine possible applications to aid our drive for recovery and increased production levels.

 The Pacific Decadal Oscillation
PDO has since been described as a long-lived El Niño-like pattern of Pacific climate variability because the two climate oscillations have similar spatial climate fingerprints, but very different temporal behavior.
For example, if PDO arises from air-sea interactions that require 10 year ocean adjustment times, then aspects of the phenomenon will (in theory) be predictable at lead times of up to 10 years.
Warm phases of PDO are correlated with El Niño-like North American temperature and precipitation anomalies, while cool phases of PDO are correlated with La Niña-like climate patterns.

 WeberDev.com -> PHP Manual -> PDO Functions
Note that you cannot perform any database functions using the PDO extension by itself; you must use a database-specific PDO driver to access a database server.
You may also need to enable the PDO driver for your database of choice; consult the documentation for database-specific PDO drivers to find out more about that, but note that if you build PDO as a shared extension, you must build the PDO drivers as shared extensions.
SQLite extension depends on PDO so if PDO is built as a shared extension, SQLite needs to be built the same way.

 PDO PAPER
The signature of the PDO is clearly evident in the wintertime surface climate record for much of North America, but not for that of the other continents.
The PDO is positively correlated with wintertime precipitation along the coast of the central Gulf of Alaska and over northern Mexico and south Florida, and negatively correlated with that over much of the interior of North America and over the Hawaiian Islands.
During positive PDO years the annual water year discharge in the Skeena, Fraser, and Columbia Rivers is on average 8%, 8%, and 14% lower, respectively, than that during negative PDO years.

PDO is a new database API that will be part of the official PHP 5.1 release.
AFAIK, PDO will not be a full-fledged database abstraction library, but will provide a standard database API for PHP.
Highlights of PDO include the unified object-oriented API, compiled statements are now first class objects (the PDOStatement class), and better support for bind variables, which will give a substantial speed boost for performance freaks.

 OSR's ntdev List: Multiple FDOs for a Single PDO ?
Also, if we can have multiple FDOs, then they should be possible on a sin gle PDO (because otherwise doesn't it mean that we would have to modify the corresponding Bus Driver to create multiple PDOs for the device it enumer ates, and my understanding is that Bus Drivers are standard).
Each PDO has a PnP enumeration ID, and the PnP manager uses that ID to select a single Driver as the target for an AddDevice operation.
If an IRP is passed from a PDO02 pdo to FDO-1 (and from there to PDO-1) that is a function of an internal design of Driver-2 and not part of the Wdm design.
