    Abstract: A characterized cell library for EDA tools includes one or more mathematical models for each cell, and one or more preconditioning functions (and/or inverse preconditioning functions) for each mathematical model. Each mathematical model represents a performance parameter (e.g., delay, power consumption, noise) or a preconditioned performance parameter of the cell. The preconditioning functions convert an operating parameter (e.g., input slew, output capacitance) associated with the performance parameter into a preconditioned input variable for the mathematical models. In doing so, the preconditioning functions allow for more accurate modeling of complex data relationships without increasing the complexity (e.g., order and number of coefficients) of the mathematical models. Also, because the cell library can be substantially similar to conventional polynomial-based cell libraries except for the inclusion of preconditioning functions, preconditioning does not significantly increase storage requirements and conventional EDA tools can be readily adapted to use the preconditioned cell library.

    Abstract translation: 用于EDA工具的特征化单元库包括用于每个单元的一个或多个数学模型，以及用于每个数学模型的一个或多个预处理函数（和/或反向预处理函数）。 每个数学模型表示单元的性能参数（例如，延迟，功耗，噪声）或预处理的性能参数。 预处理功能将与性能参数相关联的操作参数（例如，输入转换，输出电容）转换为用于数学模型的预条件输入变量。 在这样做时，预处理功能允许复杂数据关系的更准确的建模，而不增加数学模型的复杂性（例如，系数的顺序和数量）。 另外，由于除了包含预处理功能之外，细胞库可以基本上类似于常规的基于多项式的细胞库，所以预处理不会显着增加存储要求，并且常规EDA工具可以容易地适应于使用预处理细胞库。

    Abstract: Novel proton exchange membrane fuel cells and direct methanol fuel cells with nanostructured components are configured with higher precious metal utilization rate at the electrodes, higher power density, and lower cost. To form a catalyst, platinum or platinum-ruthenium nanoparticles are deposited onto carbon-based materials, for example, single-walled, dual-walled, multi-walled and cup-stacked carbon nanotubes. The deposition process includes an ethylene glycol reduction method. Aligned arrays of these carbon nanomaterials are prepared by filtering the nanomaterials with ethanol. A membrane electrode assembly is formed by sandwiching the catalyst between a proton exchange membrane and a diffusion layer that form a first electrode. The second electrode may be formed using a conventional catalyst. The several layers of the MEA are hot pressed to form an integrated unit. Proton exchange membrane fuel cells and direct methanol fuel cells are developed by stacking the membrane electrode assemblies in a conventional manner.

    Abstract: An enhanced library accessible by an EDA tool can include a base curve database and a plurality of curve data sets. Each curve data set refers to a standard cell having certain timing characteristics. To determine those timing characteristics, each curve data set identifies at least one base curve (in the base curve database) as well as a starting current, a peak current, a peak voltage, and a peak time. In one embodiment, each base curve can be normalized. The base curve(s), the starting current, peak current, peak voltage, and peak time can accurately model the functioning of the IC device, e.g. represented by an I(V) curve.

    Abstract: The inventive system includes a host, a network including a security gateway, and a public application. Established are an access session between the network and the host and an application session between the public application and the network. An application session record is created for the application session, and includes the user's public user identity used to access the public application, the user's private user identity used to access the network, a host identity, and an application session time. To determine the private user identity for the application session, the security gateway sends a query with the host identity and the application session time. These are compared with the host identity and access session time in an access session record. If they match, then the private user identity in the access session record is returned, and it is stored as the private user identity in the application session record.
