Oscillation criteria for a class of partial difference equations
Oscillation Partial difference equation Continuous variables
2010/9/10
In this paper we consider the partial difference equation with continuous
variables, Some sufficient conditions for all solutions of this equation
to be oscillatory are obtained.

2010/9/13
In this paper, we give some results of the oscillations criteria of the solution for some higher - order equations with deviating arguments , and note of the impulsive hyperbolic equations.We get some...
Association Between Ice Conditions in the Baltic Sea along the Estonian Coast and the North Atlantic Oscillation
Ice Conditions Baltic Sea Estonian Coast North Atlantic Oscillation
2009/10/22
Variations in time series of sum of negative degree-days, number of days with
ice, date of ice break-up and maximum ice thickness on the Baltic Sea along the
Estonian coast have been examined within...
North Atlantic Oscillation;a Climatic Indicator to Predict Hydropower Availability in Scandinavia
Climatic Indicator Predict Hydropower Availability Scandinavia
2009/10/22
Climate variability and climate change are of great concern to economists and
energy producers as well as environmentalists as both affect the precipitation
and temperature in many regions of the wo...
Preliminary study of residual orbit oscillation in BEPCⅡ
local orbit bump residual orbit oscillation Librea Electron BPM processor turn-by-turn
2009/8/14
BEPCII has two rings each with an injection system. The injection system of each ring consists of two kicker magnets and a septum magnet. The injection layout of two rings is the same. Both two kicker...
The dielectric calibration of capacitance probes for soil hydrology using an oscillation frequency response model
soil hydrology oscillation frequency response model
2009/5/27
Capacitance probes are a fast, safe and relatively inexpensive means of measuring the relative permittivity of soils, which can then be used to estimate soil water content. Initial experiments with ca...
Defining the climatic signal in stream salinity trends using the Interdecadal Pacific Oscillation and its rate of change
Interdecadal Pacific Oscillation Interdecadal Pacific Oscillation
2009/5/8
The impact of landuse on stream salinity is currently difficult to separate from the effect of climate, as the decadal scale climatic cycles in groundwater and stream hydrology have similar wavelength...
Interannual variability of winter precipitation in the European Alps:relations with the North Atlantic Oscillation
winter precipitation North Atlantic Oscillation European Alps
2009/4/27
The European Alps rely on winter precipitation for various needs in terms of hydropower and other water uses. Major European rivers originate from the Alps and depend on winter precipitation and the c...

Steric Contribution to the Seasonal Oscillation of Sea Level off Oregon
Seasonal Oscillation Sea Level off Oregon
2009/3/26
Thermal, haline and total steric departures of sea level were calculated in a zone up to 165 n mi off Newport, Ore. The thermal and haline components were about equal in magnitudes and in phase, givin...

INTERACTION BETWEEN VARIABLE SOLAR UV RADIATION AND TROPOSPHERIC CIRCULATIONS AS A POSSIBLE CAUSE OF FIVE YEAR OSCILLATION IN EARTH ROTATION
VARIABLE SOLAR UV RADIATION TROPOSPHERIC CIRCULATIONS EARTH ROTATION
2009/3/16
It is shown that Five Year Oscillation in Earth rotation is possibly
caused by variable solar UV radiation and a corresponding perturbation mechanism
is suggested.
Long-term patterns in dissolved organic carbon in boreal lakes: the role of incident radiation, precipitation, air temperature, southern oscillation and acid deposition
dissolved-organic-carbon lakes climate solar-radiation
2009/3/12
Both lake-specific (e.g. pH) and regional (e.g. precipitation) factors affect DOC concentration and pattern. Using annual DOC concentration in nine boreal lakes in the ice-free season, the potential i...
