Due to the turbulent external business environment, the complexity of internal relations of the organization and the emergence of subversive IT roles, the business-IT alignment(BITA)has become increasingly difficult. The unsuccessful realization of BITA will lead to the waste of organizational resources, the reduction of return on investment and eventually the loss of competitive advantage. In recent years, coevolution has received widespread attention due to its ability to describe the dynamic relationship between IT and business. Multiple principles such as quickening learning action loops and adopt suitable organizing principles for achieving business and IT coevolution(BITC) are obtained. However, the continuous BITC is still hard to be achieved because of the lack of complete BITC management. This paper focuses on the management process of the BITC and how to perform it gradually. A coevolution framework combines the enterprise architecture(EA) approach with the coevolution analysis is proposed, which contains the design of EA, the sensing and governance of the misalignment and the procedure of the EA misalignment *** steps for the governance and prevention of misalignment are discussed in particular. Through comparison with the principles,characteristics and methods of coevolution in the literature, the proposed framework is evaluated. The results show that the proposed framework is effective for BITC implementation.

New Stability Criteria for High-Order Neural Networks with Proportional Delays

引用

Communications in Theoretical Physics 2017年第3期67卷 235-240页

作者：徐昌进李培峦 Guizhou Key Laboratory of Economics System Simulation Guizhou University of Finance and Economics School of Mathematics and Statistics Henan University of Science and Technology

This paper is concerned with high-order neural networks with proportional delays. The proportional delay is a time-varying unbounded delay which is different from the constant delay, bounded time-varying delay and distributed delay. By the nonlinear transformation yi(t) = ui( et)(i = 1, 2,..., n), we transform a class of high-order neural networks with proportional delays into a class of high-order neural networks with constant delays and timevarying coefficients. With the aid of Brouwer fixed point theorem and constructing the delay differential inequality, we obtain some delay-independent and delay-dependent sufficient conditions to ensure the existence, uniqueness and global exponential stability of equilibrium of the network. Two examples with their simulations are given to illustrate the theoretical findings. Our results are new and complement previously known results.

Chaos Control and Bifurcation Behavior for a Sprott E system with Distributed Delay Feedback

引用

International Journal of Automation and computing 2015年第2期12卷 182-191页

In this paper, the problem of controlling chaos in a Sprott E system with distributed delay feedback is considered. By analyzing the associated characteristic transcendental equation, we focus on the local stability and Hopf bifurcation nature of the Sprott E system with distributed delay feedback. Some explicit formulae for determining the stability and the direction of the Hopf bifurcation periodic solutions are derived by using the normal form theory and center manifold theory. Numerical simulations for justifying the theoretical analysis are provided.

As the processor has entered the multi-core/many-core era, the parallel processing capability of a single processor can be improved in scale with increasing cores. However, for the high performance computation (HPC) clusters, the improvement of inter-node communication latency is far behind of the performance improvement of processors. As a result, communication latency often becomes the performance bottleneck of most HPC applications. This paper focuses on solving the communication latency problem of adjacent inter-action simulation on multi-core/many-core clusters, and pro-poses an optimized algorithm for adjacent interaction simula-tion on modern general purpose graphic many-core architec-tures and an O(B+2R) algorithm for inter-node latency- hiding. The theoretical analysis and experimental result show that the techniques proposed in this paper can effectively improve the performance of adjacent interaction simulation on multi-core/many-core clusters. © Springer-Verlag Berlin Heidelberg 2013.

The number of channels for radio frequency simulation system is very limited, and the traditional simulation method of one channel simulating one target is difficult to meet the demand of complex scene simulation. This paper proposes a simulation method based on the triadic vector control algorithm of "both amplitude and phase control" to simulate the angular position of multiple radar targets by one channel, and further researches the simulation method based on digital radio frequency memory technology to simulate the multidimensional characteristics of multiple radar targets such as delay, doppler frequency, amplitude and angle by one channel. Mathematical simulation experiments are designed to verify the feasibility of the method. © 2023 SPIE.

How to effectively control the cost of software development and improve the cost efficiency has always been the focus of party A. Software cost estimation process is discussed in this paper, we studied the purchasing behavior of both sides, based on the game theory to build the party A and party B the purchase price game model of the enterprise, won the party A and party B to take different strategies of Nash equilibrium, the two sides are discussed under different parameters of the strategy, the analysis result was combing inductive. It is pointed out that demonstration + price review is the best choice of party A's price control method, which can reduce the cost of audit and have a deterrent effect on party B's enterprises, so as to standardize the quotation behavior of enterprises. The analysis also points out that the control of software development cost should be balanced comprehensively, and economic benefit should not be emphasized blindly. © 2022 Copyright for this paper by its authors.
