Optimal design study of high order FIR digital filters based on neural network algorithm

An optimal design approach of high order FIR digital filter is developed based on the algorithm of neural networks with cosine basis function . The main idea is to minimize the sum of the square errors between the amplitude response of the desired FIR filter and that of the designed by training the weights of neural networks, then obtains the impulse response of FIR digital filter . The convergence theorem of the neural networks algorithm is presented and proved, and the optimal design method is introduced by designing four kinds of FIR digital filters , i.e., low-pass, high-pass, bandpass , and band-stop FIR digital filter. The results of the amplitude responses show that attenuation in stop-bands is more than 60 dB with no ripple and pulse existing in pass-bands, and cutoff frequency of passband and stop-band is easily controlled precisely .The presented optimal design approach of high order FIR digital filter is significantly effective.     

A STACKELBERG DIFFERENTIAL GAMES SOLUTION TO A PROBLEM OF OPTIMAL INTERTEMPORAL INVESTMENT AND TAX RATE DESIGN

Using the Stackelberg differential games(SDG) theory, we quantitatively study a problem of optimal intertemporal investment and tax rate design. Under some appropriate assumptions, the open-loop Stackelberg equilibrium solutions are obtained. Equilibrium solutions show that: 1. The optimal strategies derived from differential game and unilateral optimal control approaches are different; 2. It is not always the best strategy for the government to use a constant tax rate over the whole time period; 3. The admissible size of tax rate adjustment may have great effect on the government's optimal strategy; 4. SDG approach has no significant effect on the firm's optimal investment strategy.     

Repositing Thinking for Future Social Systems Design: In Tribute to Bela H. Banathy and His Inspiration of the Fuschl Conversations

Contemporary systems activity can be divided into that stressing feasible and practical short-term measures, and that which is more ideal-aware, focussed on mid-longer term futures, and typically involving on-going community or social systems design. The paper highlights the key differences in approach, but then invites closer collaboration in the cause of the possible contribution that systems thinking could make for a longer term future, with Y3K (Year 3000) as a metaphor for this. This analysis, which derives from work undertaken at Asilomar 1995 and Fuschl conversations in 2000 and 2002, finds that contemporary social system design, which is driven by western culture and is action-oriented, needs adaptation before it could contribute to greater future global harmony. A truly comprehensive systems design process must accommodate a wide range of possible parameters in terms of culture, and appreciation of time and progress. An emerging paradigm as basis for thinking and engaging in social systems design work of the future is offered, which also has relevance to general systems practice.
