This paper considers an application of the Markov switching vector error correction model to analysis long-run and short-run dependence Russian real GDP exchange on oil prices. An algorithm for estimation with a priori information state hidden chain in some periods time is provided. It shown that period 1999–2018 two different regimes are well defined: slow adjustment rate sharp reaction respon...

This paper investigates the induced stresses in circular single deck roofs floating on seismically excited storage tanks. Equations of motion are derived using variational principle. Response of deck floating roofs is evaluated for two different classes of ground motions; near-source and long-period far-field records. Besides time histories and frequency contents for a specific tank, peak value...

Floating-point computations are usually performed with fixed precision: the machine used may have “single” or “double” precision floating-point hardware, or on small machines fixed-precision floating-point operations may be implemented by software or firmware. Most high-level languages support only a small number of floating-point precisions, and those which support an arbitrary number usually ...

Due to technological advances, it has become possible to implement floating-point cores on FPGAs in an effort to provide hardware acceleration for the myriad applications that require high performance floating-point arithmetic. However, in order to achieve a high clock rate, these floating-point cores must be deeply pipelined. Due to this deep pipelining and the complexity of floating-point ari...

wide fluctuations of the prices of chicken and egg along with the containment of these fluctuations always matter to producers, consumers and government. these fluctuations are affected by various factors on the supply and demand sides of the product and its inputs. the results of this research are as follows: contributing 1.5 and 1 per cent to the world production of chicken (76.3 million tons...

Floating Point operations is widely used in many areas, especially in signal processing. The greater dynamic range and lack of need to scale the numbers makes development of algorithms much easier. However, implementing arithmetic operations for floating point numbers in hardware is very difficult. The IEEE floating point standard defines both single precision (32-bit) and double precision (64-...

A novel digitally programmable floating impedance converter circuit is realized using two CMOS digitally programmable differential voltage current conveyors and three grounded passive elements. The realized impedance converter can provide digitally programmable floating impedances like ideal floating resistor, capacitor, inductor and frequency dependent negative resistor through appropriate sel...

Abstract Using two basic assumptions of time series analysis, a test is proposed to assess the quality of seasonal adjustment of a series. The test is applied to several seasonally adjusted series of the Consumer Price Index (CPI) using three methods of seasonal adjustment: State Space Model Based Method (SSMB), TRAMO SEATS Method and X12ARIMA method. The empirical results are presented along w...

A shadow price is a process S̃ lying within the bid/ask prices S, S of a market with proportional transaction costs, such that maximizing expected utility from consumption in the frictionless market with price process S̃ leads to the same maximal utility as in the original market with transaction costs. For finite Ω, this note provides an elementary proof for the existence of such a shadow price.
