Abstract. Benthic oxygen isotope records are commonly used as a proxy for global mean surface temperatures during the Late Cretaceous and Cenozoic, resulting estimates have been extensively in characterizing major trends transitions climate system analysing past sensitivity. However, some fundamental assumptions governing this rarely tested. Two key (a) benthic foraminiferal geographically well...

‎financial market modeling and prediction is a difficult problem and drastic changes of the price causes nonlinear dynamic that makes the price prediction one of the most challenging tasks for economists‎. ‎since markets always have been interesting for traders‎, ‎many traders with various beliefs are highly active in a market‎. ‎the competition among two agents of traders‎, ‎namely trend follo...

abstract: vacuum deep-fat frying is a new technology that can be used to improve the quality attributes of fried food because of the low temperatures employed and minimal exposure to oxygen. in this paper the effect of frying process parameters, namely frying time, frying temperature and pressure on the quality factors of fried kiwi slices was studied. a laboratory scale vacuum frying apparatus...

Fragmentation of nuclear system by tunneling is discussed in a molecular dynamics simulation coupled with imaginary time method. In this way we obtain informations on the fragmenting systems at low densities and temperatures. These conditions cannot be reached normally (i.e. above the barrier) in nucleus-nucleus or nucleon-nucleus collisions. The price to pay is the small probability of fragmen...

this paper examines regime shifts in tedpix return and volatility and the effects of positive and negative crude oil shocks and gold price fluctuations on stock market shifts behavior using markov switching egarch model with student’s t-distribution. we detect two episodes of series behavior, one relative to low mean/high variance regime namely bear state and the other to high mean/low variance...

This paper examines the implications of network externalities on equilibrium outcomes in a differentiated products duopoly under strategic managerial delegation through relative performance based incentive contracts. It shows that Miller and Pazgal (2001)'s equivalence result does not go through in the presence of network externalities. Instead, Singh and Vives (1984)'s rankings of equilibrium ...

Rice plays an especial role in Iranian households' nutrition basket. The volatilities of its price during recent years caused consumers' dissatisfaction. This paper investigates spillover effects of price volatilities (at the wholesale and retail levels) in the Guilan Province rice market. The Generalized Autoregressive Conditional Hetroscedasitic (GARCH) model was used for the monthly time per...

Price forecast is a task challenging and very important in competitive electricity market context. Both market players and regulators concern very much about the price evolution, on one hand, the prediction of the market price is a crucial information for the production arrangement and bidding strategies. On the other hand, the regulators need to analyze the market behavior and monitor the mark...

Modern information and communication technologies used by electric power grids are subject to cybersecurity threats. This paper studies the impact of integrity attacks on real-time pricing (RTP), an emerging feature of advanced power grids that can improve system efficiency. Recent studies have shown that RTP creates a closed loop formed by the mutually dependent real-time price signals and pri...

National health expenditures are projected to grow to $640 billion by 1990, 11.3 percent of the gross national product. Growth in health spending is expected to moderate to an 8.7 percent average annual rate from 1984 to 1990, compared with a 12.6 percent rate from 1978 to 1984. These projections assume lower estimates of overall economic price growth, lower use of hospital care, and increased ...
