Personality and the Two Ways of Regulating Emotion
… of personality in terms of human functioning in time and space, as a whole system of personality dynamics. The aim of the study was to explore this concept using psychophysiological methods to examine distinctions between personalities during emotion generation and regulation. Specifically, the …

ΑΝΑΛΥΣΗ ΤΙΜΩΝ ΞΥΛΟΥ ΜΕ ΤΗ ΧΡΗΣΗ ΜΟΝΟΜΕΤΑΒΛΗΤΩΝ ΜΕΘΟΔΩΝ (ΧΡΟΝΙΚΕΣ ΥΣΤΕΡΗΣΕΙΣ ΚΑΙΜΕΘΟΔΟΥΣ BOX-JENKINS)
… ANSWER TO THE QUESTION: CAN THE TWO METHODOGIES (TIME LAGS AND BOX-JENKINS METHODOLOGY) GIVE A SATISFACTORY APPROACH TO THE PROBLEM OF DEFINING THE STARTING PRICES OF THE TIMBER BEING SOLD IN THE PUBLIC AUCTIONS. IN TOTAL WE HAVE EXAMINED 31 MODELS (11 OF TIME LAGS AND 20 OF THE BOX- JENKINS …

Case Studies of IMF Driven Auroral Emissions
… to identify events of interest. The observed time lags from the power spectrums were then compared to the calculated time lags. There were 6 events on 4 days, May 6 2008, May 10 2007, August 14 2006, and August 15 2006. Location relative to the ecliptic plane appeared to be of importance. For …

Unsteady Skin-Friction Measurements on a Maneuvering Darpa2 Suboff Model
… region of the sail-on-side case show significant time lags between unsteady and steady crossflow separation locations. These effects produce the difference in separation topology between the unsteady and steady flowfields. A first-order time lag model approximates the unsteady separation locations …

Permeation studies of hydrogen, deuterium and helium in aluminium, gold molybdenum and silver: the influence of phase boundary processes
… silver has been studied by a modified response time method using periodically modulated discharge and ion beam injection at the input surface. Measurements consisted of the response time of pressure, across a metal membrane, in the detection chamber due to fluctuations at the input. The …

Time-scales of passive tracers in the ocean with paleoapplications
Quantifying time-responses of the ocean to passive and active tracers is critical when interpreting paleodata from sediment cores. Surface-injected tracers are not spreading instantaneously or uniformly throughout the ocean. To obtain insights into these time-scales, a transition matrix is used to …

Estimating Trophic Position of Lake Oahe Walleye Using Stable Isotope Analysis
… for determining changes in prey use, they can be time and labor intensive. Furthermore, they offer only a snapshot of recent feeding patterns when populations are sampled infrequently. I used stable isotope analysis to estimate walleye trophic position and then compared these values to trophic …

UN Peacekeeping Impacts on Human Rights
… abuses five years in the future. Differences in time lags also suggest that the larger multidimensional and enforcement missions are more effective for future rights, whereas smaller traditional missions can be sufficient in impacting current human rights performances. These inferences apply to …

Computerized feedback control of an environmental chamber
… a given concentration. Software response time is slow. This causes time lags in the modification of the controlled parameters to achieve desired values. The heating and cooling characteristics of the system can be improved by better insulation of the chamber walls. The system demonstrates …

Rent adjustment mechanism for the multifamily housing market
… ultimately determines rent levels. Various time lags on the vacancy rate are tested for each metropolitan area in order to better understand the timing of the effect of the vacancy rate on market rents and to find the best fitting model for each metropolitan area. Two kinds of rents are …

Investigating beef cattle prices for short time periods
… quarterly and monthly economic models. Various time lags and alternative algebraic variable forms were investigated. Consideration was given to both seasonally and non-seasonally adjusted data. A model using three seasonally adjusted variables was postulated to explain the variation in …

Spectral Solution Method for Distributed Delay Stochastic Differential Equations
… system, and obtain expressions for the system's time-dependent mean and autocovariance. These are in the form of series over the system's natural modes and completely define the solution. — An interpretation of the system as an amplitude process is explored. We show that for a wide range of …

The Structure-Function Relationships in Laminated Barrier Films
… single films were permeable to water; though no time-lags were evident. The permeability to BHT and e-caprolactam varied, polyethylene being most permeable, PETP impermeable with nylon lying between. Adhesives as used in laminates were studied as films and were permeable to water. Water uptake …
