This study compared Hispanic children (ages 7 to 11) with combined type (CT, n=33) and inattentive type (IT, n=21) attention deficit hyperactivity disorder (ADHD) and a control group (n=25) on time-estimation and time-reproduction tasks. The ADHD groups showed larger errors in time reproduction but not in time estimation than the control group, and the(More)
As designers become more aggressive in introducing optical components to micro-systems, rigorous optical models are required for system-level simulation tools. Common optical modeling techniques and approximations are not valid for most optical micro-systems, and those techniques that provide accurate simulation are computationally slow. In this paper, we(More)
—We present a component-based multi-level mixed-signal design and simulation environment for microsystems spanning the domains of electronics, mechanics, and optics. The environment provides a solution to the problem of accurate modeling and simulation of multi-domain devices at the system level. This is achieved by partitioning the system into components(More)
Chatoyant models free-space opto-electronic components and systems and performs simulations and analyses that allow designers to make informed system level trade-offs. Recently, the use of MEM bulk and surface micro-machining technology has enabled the fabrication of micro-optical-mechanical systems. This paper presents our models for diffractive optics and(More)
Design exploration is most often accomplished in a design, analysis, evaluate loop which is limited by the speed and quality of the simulation tools used for analysis and evaluation. For new technologies these simulations are often ad-hoc and incompatible with traditional simulation environments. Therefore, it is challenging to model systems composed of(More)
We present our system-level co-simulation environment for mixed domain microsystems. Theenvironment provides synchronization and cosimulation between the Chatoyant MOEMS (Micro-Electro Mechanical Systems) simulator and ModelTech ModelSim. By using shared memory IPC (Inter-Process Communication) and PDES (Parallel Discrete Event Simulation) techniques, we(More)
