EIA-0130812 Andreas G. Andreou Johns Hopkins University A Comparative Study of Information Processing in Biological and Bio-inspired systems: Performance Criteria, Resources Tradeoffs and Fundamental LimitsWe propose a research program towards a fundamental and quantitative understanding of the tradeoffs between system performance and resources such as size, reliability and energy requirements for biological and bio-inspired microsystems. We employ the mathematical tools of communication theory and model natural or synthetic physical structures as micro-scale communication networks, studying them under physical constraints at two different levels of abstraction. At the functional level we examine the operational and task specification, while at the implementation level we examine the physical specification and realization. Both levels of abstraction are characterized by Shannon's channel capacity, as determined by the channel bandwidth, the signal power; and the noise power. The link between the functional level and the physical level of abstraction is established through first principles and phenomenological otherwise, models for transformations on the signal, physical constraints on the system, and noise that degrades the signal.

EIA-0130812 Andreas G. Andreou Johns Hopkins大学对生物学和生物启发系统中信息处理的比较研究：绩效标准，资源折衷和基本限制，我们建议一项研究计划，以对系统绩效和资源之间的基本和定量理解，诸如对生物的尺寸和资源之间的折衷和资源，诸如生物和能源需求和Biosic和Biocio-Insspiredspiirdspiire-Inspiir-Inspiirdspiired。 我们将通信理论的数学工具和模型自然或合成物理结构作为微型通信网络，在两个不同级别的抽象级别的物理约束下研究它们。 在功能层面，我们检查了操作和任务规范，而在实现级别，我们检查了物理规范和实现。 两种抽象水平的特征在于香农的通道容量，由信号频道（信号功率）确定。和噪声功率。 功能水平与抽象的物理水平之间的联系是通过第一原理和现象学建立的，否则，信号转换的模型，系统上的物理约束以及降解信号的噪声。
