Accurate driver and package models are necessary to analyze the signal integrity (SI) and electromagnetic compatibility (EMC) issues on digital circuits. 2-pole models that assume an ideal power distribution system (PDS) are commonly used in modeling the SI of signal lines. This assumption makes real SI and EMC analysis worthless or at least only useful under certain restrictions. In order to a...

Legislators, journalists, and researchers alike have recently directed a great deal of attention to the effects of cellular telephone (‘cell phone’) use on driver behavior and performance. This paper demonstrates how cognitive modeling can aid in understanding these effects by predicting the impact of cell-phone dialing in a naturalistic driving task. We developed models of four methods of cell...

Driver heterogeneity in travel behavior has repeatedly been cited in the literature as a limitation that needs to be addressed. In this work, driver heterogeneity is addressed from four different perspectives. First, driver heterogeneity is addressed by models of driver perceptions of travel conditions: travel distance, time, and speed. Second, it is addressed from the perspective of driver lea...

With submicron technologies, gate delays are dominated by gate load delays rather than intrinsic gate delays. While the common approach for computing gate load delay (or total gate delay) is through delay tables (or k-factor equations), there are important methodology problems associated with the delay table approach. In this paper, we propose a gate driver model with a Thevenin equivalent circ...

The future trend of controller integrated circuit (IC) for micro hard disk driver (HDD) is to be lighter, thinner, shorter and smaller. The storage capacity and unit cost of micro HDD is lower than of flash memory card. The optimal packaging manufacturing process for driver IC for micro HDD is Chip Scale Package (CSP). However, the production and assemble process for CSP is much more difficult....

A new approach to driver seat-position modeling is presented. The equations of the Seating Accommodation Model (SAM) separately predict parameters of the distributions of male and female fore/aft seat position in a given vehicle. These distributions are used together to predict specific percentiles of the combined male-andfemale seat-position distribution. The effects of vehicle parameters—seat...

Accurate classification of eye state is a prerequisite for preventing automobile accidents due to driver drowsiness. Previous methods of classification, based on features extracted for a single eye, are vulnerable to eye localization errors and visual obstructions, and most use a fixed threshold for classification, irrespective of variations in the driver’s eye shape and texture. To address the...

This paper proposes Multi-stream Minimum Acceptable Space (MMAS) Cellular Automata (CA) models to simulate driver behavior and its effects on traffic flow at three-lane roundabouts. Using cellular automata, the models are developed by modeling the detailed space considerations for drivers entering un-signalized threelane roundabouts. Heterogeneity and inconsistency of driver behavior and intera...

This paper shows how two different theoretical approaches to model innovation adoption, network threshold modeling and random utility modeling, both result in discrete-time hazard models, a popular statistical modeling approach to study innovation adoption and diffusion. The paper emphasizes the need for careful situational analysis prior to model building and illustrates the point with the dif...
