Abstract Regional water allocation is of great importance to regional coordinated development. Therefore, this paper constructs a data-driven model for analysis address the existing problems imbalance between supply and demand, irrational utilization resources scarcity. Firstly, classification case constructed through cluster obtain similar regions with same salient characteristics. Then, in ca...

Abstract After a tense process of renegotiating the terms NAFTA (North American Free Trade Agreement), governments United States, Mexico and Canada established new regional agreement, USMCA (United whose purpose is to overcome problems that emerged since came into force in 1994. The ratification this document by national congresses referred countries has generated tensions instabilities their p...

Regional economy is a human economic activity in geographical region, prominent and sustainable with distinctive regional characteristics. characterized by its integrity, relativity, relative independence, spatial difference. With the increasing development of science technology big data, it has become normal trend to use artificial intelligence solve current social problems. In this paper, pro...

the square map is one of the functions used in cryptography. for instance, the square map is used in rabin encryption scheme, block cipher rc6 and stream cipher rabbit, in different forms. in this paper, we study statistical properties of the output of the square map as a vectorial boolean function. we obtain the joint probability distribution of arbitrary number of the upper and the lower bits...

The inphase/quadrature (I/Q) amplitude and phase imbalance effects are studied in coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems. An analytical model for the I/Q imbalance is developed and supported by simulation results. The results indicate that the I/Q imbalance degrades the BER performance considerably. Keywords—Coherent detection, I/Q imbalance, OFDM, optical...

WiMAX systems are very popular in wireless communication now-a-days. The main reason behind its popularity is high data rates possible in WiMAX systems. But due to in-phase quadrature imbalance (i.e. IQ imbalance) at the transmitter (Tx) and receiver (Rx), the system performance may be degraded in WiMAX systems. Therefore, it is necessary to compensate for the in-phase quadrature imbalance. In ...

We construct a theoretical model to interpret the structural shock from COVID-19 pandemic and response of local labour market industry specialization. The empirical study takes large-scale online China analyse firms’ hiring demand for 20 industries across 380 cities with monthly recruitment data May 2017 September 2020. Post-event quantitative analysis on job postings employer highlighted that ...

Workload construction methodologies for multiprogram experiments are more complicated than those for single-program experiments. Fixed-workload methodologies pre-select samples from each program and use these in every experiment. They enable direct comparisons between experiments, but may also yield runs of which significant portions are spent executing only the slowest program(s). Variable-wor...
