Topic: Dissipation


In the News (Wed 15 Oct 08)

  
  Dissipation - Wikipedia, the free encyclopedia
The precise nature of the effects depends on the nature of the wave: an atmospheric wave, for instance, may dissipate close to the surface due to friction with the land mass, and at higher levels due to radiative cooling.
In computational physics, a numerical dissipation is also known as "artificial dissipation" or "artificial diffusion" or "numerical diffusion".
Dissipation is the process of converting mechanical energy of downward flowing water into thermal and acoustical energy.

 The Gitlin Law Firm - Woodstock, Illinois -- Dissipation in Illinois Divorce Cases Q&A
Dissipation is limited to the time period at a time period where the marriage is undergoing (or has undergone) an irretrievable breakdown.
Dissipation generally reduces the amount of marital property which the court can divide between the parties because the dissipated property is essentially awarded to the property who was responsible for the use or expenditure of marital funds.
Dissipation can also take the form of buying things for yourself which are reasonable and necessary, such as expensive jewelry, expensive clothing, new cars, etc. Dissipation can also include mismanagement of a family business, excessive expenditures on hobbies, legal fees, expensive vacations, failing to pay mortgage payments, and gifts to relatives.

 DCBA Brief, May 2001 - What Constitutes Dissipation of Marital Assets?
Dissipation is generally defined as the use of marital property for the sole benefit of one spouse, for a purpose unrelated to the marriage at a time when the marriage is undergoing an irreconcilable breakdown.
The court reasoned that no provision in the IMDMA limits dissipation to a time period when the marriage is undergoing an irretrievable breakdown, and similarly no argument had ever been made that contributions should be limited to a specific period of time during a marriage.
The person accused of dissipation is under an obligation to establish by clear and specific evidence how marital funds were spent, and to prove that the funds were spent for legitimate marital expenses.

 Dissipation of Marital Assets in Illinois: A Review; September 2003
(1) the contribution or dissipation of each party in the acquisition, preservation, or depreciation or appreciation in value, of the marital and non-marital property, including the contribution of a spouse as a homemaker or to the family unit;....
The alleged dissipation took place during the six years between the entry of the judgment dissolving the marriage and the final hearing on the property division.
Dissipation cases sometimes involve gambling, paramours, extraordinary and undocumented expenses, and the disappearance of marital funds under the control of one party.

 The Relations between Replication and Dissipation regarding Life and Existence
There are different kinds and degrees of replication and dissipation, so the there can be a large amount of specific relations between the two depending on the specifics of what is dissipated and replicated within, through out, out of, the entity in question.
In particular, life is a functional response to a kind of complex material dissipation, and since replication is entangled with dissipation, life's replicative ability is a result of a kind of material dissipation.
The problems and solutions of the functions: existence and non-existence, replication and dissipation, stability and non-stability, control and non-control, inheritance and non-heritance, somatic life and death, knowledge and ignorance, learning and stupidity will in the future serve as a general backdrop in understanding the functions of various forms of life.

 NAFTA Guidance Document for Conducting Terrestrial Field Dissipation Studies | Pesticides: Environmental Effects | US ...
The basic TFD study focuses on pesticide dissipation from the soil surface layer in a bareground study; it can be used to estimate field degradation only when other major routes of dissipation (e.g., sorption and binding, leaching, volatilization, runoff and plant uptake) are quantified and shown to be negligible.
Such an application is misleading when reported dissipation half-lives (often DT time for 50% dissipation of the parent chemical values and not true half-lives) include the combined routes of dissipation (degradation/transformation and transport) from the surface.

 Sermon 79 - On Dissipation   (Site not responding. Last check: 2007-10-13)
So the sun dissipates, that is, scatters, the clouds; the wind dissipates, or scatters, the dust; and, by an easy metaphor, our thoughts are said to be dissipated, when they are irregularly scattered up and down.
Dissipation then, in general, may be defined, "the uncentring the soul from God." And whatever uncentres the mind from God does properly dissipate us.
For as dissipation or ungodliness is the parent of all sin; of all unrighteousness; of unmercifulness, injustice, fraud, perfidy; of every possible evil temper, evil word, or evil action; so it, in effect, comprises them all.

 Energy Weapon Dissipation
This energy dissipation is caused by a wide variety of factors, such as the energy bean hitting particles on its way to its target, energy wasted heating the air as the beam passes through, or even loosing intensity and focus, which is very important with laser weapons.
Laser weapons initially dissipate slowly, but this changes the further away the target is. Laser weapons cause 100% damage at point blank range, 100% damage at short range, 75% at medium range, 25% at long range, and 10% damage at extreme range.
Particle bean weapons dissipate slowly overall and are more effective at most range categories because of the nature of their energy beam.

 Damping and Energy Dissipation   (Site not responding. Last check: 2007-10-13)
Another form of damping, that is often used in the mathematical model for the simulation of the dynamic response of a structure, is proportional to the stiffness and mass of the structure.
The cause of the energy dissipation may be due to many different effects such as material damping, joint friction and radiation damping at the supports.
Since the basic nature of energy dissipation is not clearly defined in real structures and viscous damping is often used to approximate nonlinear behavior, this increase in computational effort is not justified since we are not solving the real problem.

 Power Dissipation   (Site not responding. Last check: 2007-10-13)
Integrating the power dissipation of the 5.00 V and ñ5.20 V power supplies over one 10 ns period we obtain an average power dissipation of about 340 mW.
Since the power dissipation of the CMOS is frequency dependent, the higher the frequency the greater the power dissipation.
The power dissipation of the translation buffer then is also relatively constant since the transistors are all on in either the ohmic or pinch-off region.

 "On the Dissipation of the Electrical Energy of the Hertz Resonator"
Bjerknes's experiments principally this dissipation in the resonator need be considered, though the sound-waves—if this term be permitted—which emanate from the surfaces at the oscillator may considerably affect the observations made at some distance from the latter.
At present it appears certain from experiments with, high-frequency currents, that this dissipation of energy from a wire, for instance, is not very far from being proportionate to the frequency of the alternations, and increases very rapidly when the diameter of the wire is made exceedingly small.
The dissipation of energy is more rapid when the resonator is immersed in air than it would be in a practically continuous medium, for instance, oil.

Dissipation is defined as irreversible growth of average energy.
65], or the surrounding gas in the case of classical Brownian motion) which has infinite degrees of freedom, dissipation is a result of ergodicity in closed system with a small number of degrees of freedom (as little as 2).
Dissipation can be thought of as a `friction force' felt by the agency responsible for changing the parameter, which arises from ergodic motion in the system.

 EDN -- 11.09.95 calculating power dissipation of high-performance ADCs: account for operating conditions
The accepted convention is that this source of power dissipation is a constant dictated by the laws of physics and is a fixed factor in the application of all CMOS and BiCMOS ADCs.
The first test measures power dissipation with the ADC operating in a best-case condition: a nominal bit-output load capacitance of 5 pF, a conversion clock of 5 MHz, and a static dc analog input.
The calculated value for the power dissipation in the CMOS output stage at the 5M-sample/sec clock rate (with dynamic input, per the given formula, where C=5 pF and V=5V) is 0.3 mW/bit, or 3 mW total for the 10-bit converter.

 Phase Angle Vs. Transistor Dissipation
At 45 degrees, the transistor peak dissipation is doubled, compared to the case with a resistive load.
This table is for peak dissipation at the onset of clipping, and the situation is very different at worst case output level (¼ the maximum power, or ½ total voltage swing).
Peak transistor dissipation is still 70W, but the average power increases to a little over 28W because of the way amplifiers work (this topic is covered in greater depth in the Amplifier Design article).

 Divorce Source: Cases of Interest: Dissipation of Assets
The husband's dissipation of his business and its inventory did not justify stripping him of a proportionate share of the parties' marital assets, where the trial court dealt with his misconduct by awarding alimony based on imputed income and could impose other sanctions.
Waste and misuse are the hallmarks of dissipation; in determining whether dissipation has occurred, the trial court should consider the accused spouse's intent, the purpose of and benefit from the expenditure, the timing of the transaction, and the non-dissipating spouse's consent or lack of consent.
Once a spouse shows by a preponderance of the evidence that marital funds were dissipated, the burden of going forward shifts to the other spouse to prove that the funds were not expended for an improper purpose.

 Generation and dissipation of mechanical energy
It is possible that a significant portion of the energy of the ocean currents is dispersed laterally towards the shelf regions by advection associated with eddies in the main streams.
Ekman's classical theory of wind drift currents, on the other hand, calls for downward dissipation of energy associated with vertical eddies with eventual dissipation by viscous stresses at the smallest scale of turbulent eddies within the upper 300 meters of the ocean.
This implies that on the average the dissipation of energy balances the supply of energy at the sea surface together with the generation within the ocean by tidal and thermal processes.

 Wave Dissipation in WAVEWATCH III   (Site not responding. Last check: 2007-10-13)
It is parameterized based on field observations of wave breaking and the resulting wave energy dissipation.
For wavelengths greater than half of the water depth, dissipation through interaction of waves with the ocean bottom through friction needs to be accounted for (i.e., the waves start to "feel" the ocean bottom).
This dissipation is somewhat analogous to the effect of the earth's surface on the near-surface wind in the atmosphere.

This spectral break marks the onset of dissipation mechanism(s) and the region above this is thus referred to as the dissipation range.
This result stands in stark contrast with expectations from the hydrodynamic case, and, combined with the fixed frequency at which dissipation sets in, suggests that a new dissipation-range theory is required.
It is hoped that by carefully studying the dissipation range characteristics and dependences further we may begin to gain a better understanding of the mechanism(s) that convert magnetic energy into heat.

 Fluctuation dissipation theorem - Wikipedia, the free encyclopedia
In statistical physics, the fluctuation dissipation theorem is derived from the assumption that the response of a system in thermodynamic equilibrium to a small external perturbation is the same as its response to a spontaneous fluctuation.
For example, Einstein in his 1905 paper on Brownian motion noted that the same random forces which cause the erratic motion of a particle in Brownian motion would also cause drag if the particle were pulled through the fluid.
The example above turns out to be just one example of a very general result in statistical thermodynamics, the fluctuation dissipation theorem, which can be used to give an explicit relationship between molecular dynamics at thermal equilibrium, and the macroscopic response that is observed in a dynamic measurement.

 Thermal Dissipation Constant - BetaTHERM Sensors Temperature Solutions
Because the measured resistance of a thermistor at a particular time depends on the power dissipated in the thermistor during measurement and on the thermal dynamics of the system being measured, it is useful to quantify the combined effect of these two factors.
The Thermal Dissipation Constant of a thermistor is defined as the power required to raise the thermistor’s body temperature by 1°C in a particular measurement medium.
The three factors, zero-power resistance (Ro), time constant (T.C.), and dissipation constant (D.C.) influence the measured value of the resistance of a thermistor which will affect temperature values that are calculated from the resistance measurements.

 Energy and momentum dissipation through wave breaking
Laboratory and field measurements suggest that the wave field dissipation can be significantly enhanced by wave breaking and acts as a source of energy for generating current and entraining air against the effect of buoyancy forces.
In the present study, a breaking wave model is formulated by taking the acceleration threshold value of −g/2 as breaking criterion, and the statistics of breaking waves, such as breaking wave coverage per unit time, and the volume of breaking water per unit area of wave surface per unit time are estimated.
It is also demonstrated that, compared with empirical formula results, our model of energy (or momentum) dissipation rate lies between those models that estimate by empirical formula the rate of energy (or momentum) loss from a breaker with proportional coefficients 0.0085 and 0.0007.

 Joule Dissipation / Ionosphere of Venus
For sufficiently high Joule dissipation the heating due to VLF waves would have to be included in the energy budget of the ionosphere.
Nevertheless, we should determine if collisional Joule dissipation is important for these waves, as that may provide an alternative means for transferring wave energy to the plasma, in addition to the dissipation associated with resonant wave-particle interactions.
The Joule dissipation as given by (3) is the same as the Joule dissipation rate using the Pedersen conductivity, except for the factor of two which arises from the averaging over a wave cycle of the sinusoidally varying electric field.
