Time synchronization is critical to modern electrical power systems. Based on the lessons learned from the postdisturbance analysis of the August 14, 2003, northeast blackout, NERC (North American Electric Reliability Corporation) recommendations place a high priority on implementing time synchronization in data-recording devices. This eliminates or reduces the effort involved in comparing even...

Simultaneous genetic evaluations for bulls and cows obtained by mixed model procedures with an animal model incorporating all numerator relationships for artificially sired Holstein cows in northeastern United States were compared with separate (Northeast) mixed model evaluations of cows and sires for predicting genetic evaluations of progeny from dam, sire, and maternal grandsire evaluations. ...

Contrasting effects of temperature and winter mixing on the seasonal and inter-annual variability of the carbonate system in the Northeast Atlantic Ocean C. Dumousseaud, E. P. Achterberg, T.

Recently, it was reported that the relationship of the Indian southwest monsoon rainfall with El Niño– Southern Oscillation (ENSO) has weakened since around 1980. Here, it is reported that in contrast, the relationship between ENSO and the northeast monsoon (NEM) in south peninsular India and Sri Lanka from October to December has not weakened. The mean circulation associated with ENSO over thi...

Failures in national and international infrastructures have causes that stretch well beyond the specific events that trigger an accident or incident. The following pages argue that these latent causes can be traced back through the decisions of local management teams to higher-levels of public policy. For example, the 2003 blackout of areas in Canada and the USA was triggered by ‘flash overs’ t...

[1] Changes in the frequency and intensity of the prevailing northeast and east trade winds from 1973-2009 are analyzed from four land stations in the Hawaiian Islands. A nonparametric robust trend analysis indicates a downward trend in northeast trade wind frequency since 1973. At the Honolulu International Airport, northeast trade wind days usually occurred 291 days per year 37 years ago are ...

Evapotranspiration (ET) is a critical process for the climate system and water cycles. However, the spatiotemporal variations in terrestrial ET over Northeast China over the past three decades calculated from sparse meteorological point-based data remain large uncertain. In this paper, a recently proposed modified satellite-based Priestley–Taylor (MS–PT) algorithm was applied to estimate ET of ...

Northeast India, the only region which currently forms a land bridge between the Indian subcontinent and Southeast Asia, has been proposed as an important corridor for the initial peopling of East Asia. Given that the Austro-Asiatic linguistic family is considered to be the oldest and spoken by certain tribes in India, Northeast India and entire Southeast Asia, we expect that populations of thi...

Salinisation of freshwater has been identified as a serious environmental issue in Australia and around the world. Protective concentrations (trigger values) for salinity can be used to manage salinity impacts, though require locally relevant salinity tolerance information. 72-h acute salinity tolerance values were determined for 102 macroinvertebrates collected from 11 locations in four biolog...

Historically, birth registration in Northeast Brazil has presented serious quality problems, with major regional variations and gaps in knowledge. The current study proposes to evaluate the quality of birth records and identify patterns of relationships between variables that reflect maternal and infant factors in the birth certificates and allow summarizing the data on live births in the 188 m...
