发展创新民族风格的包装设计

首先揭示出民族风格是与时代风格对立统一、相互依存的一个概念。因而特定的时代需要具有时代精神的民族风格──创新民族风格。在探索此风格的过程中．我们首先要学习日本的战略，然后在学习的基础上实现超越。     

Research information: Regional architecture as a model towards sustainability

Yoshio Kato discusses the idea of village life as a model for sustainability based on better management of energy and entropy including reduced consumption, recycling and self-sufficiency. A recent house design in Japan by Kato incorporating these ideas is presented, along with questions of lifestyle and consumption that architects, their clients and others will have to consider in the transition toward sustainable design.

Evolutionary design of dynamic neural networks for evaporator control

This paper presents a novel neural network (NN) to control an ammonia refrigerant evaporator. Inspired by the latest findings on the biological neuron, a dynamic synaptic unit (DSU) is proposed to enhance the information processing capacity of artificial neurons. Treating the dynamic synaptic activity after the nonlinear somatic activity helps to capture the dynamics demarcated by the Gaussian activation pertaining to the input space. This practice leads to a remarkable reduction in curse of dimensionality. The proposed NN architecture has been compared with two other conventional architectures; one with dynamic neural units (DNUs) and the other with nonlinear static functions as perceptrons. The objective is to control evaporator heat flow rate and secondary fluid outlet temperature while keeping the degree of refrigerant superheat in the range 4–7 K at the evaporator outlet by manipulating refrigerant and evaporator secondary fluid flow rates. The drawbacks of conventional approaches to this problem are discussed, and how the novel method can overcome them are presented. An evolutionary approach is adopted to optimize the parameters of the NN controllers. Then evaporator process model is accomplished as a combination of governing equations and a sub NN resulting in a simple and sufficiently accurate model. The effectiveness of the proposed dynamic NN controller for the evaporator system model is validated using experimental data from the ammonia refrigeration plant.
