Development of a Thermal Management Methodology for a Front-End DPS Power Supply
Thermal management is a rapidly growing field in power electronics today. As power supply systems are designed with higher power density levels, keeping component temperatures within suitable ranges of their maximum operating limits becomes an increasingly challenging task. This project focuses on …

An Examination Of Urban School Governance Reform In Detroit Public Schools, 1999-2014
… </p> <p>In 1999, the Detroit Public Schools (DPS) was taken over by the state of Michigan in an effort to reform the district. In 1998 prior to the state takeover, DPS had 261 schools, 167,000 students enrolled in the district, and a $93 million budget surplus. In 2014 after several years of …

Prolate Spheroidal Sequence Based Transceivers for Time-Frequency Dispersive Channels
… this subspace, the Discrete Prolate Spheroidal (DPS) basis matched to the channel parameters is known to be optimally compact in representing the channel using a basis expansion decomposition. Unlike the Discrete Fourier Transform (DFT) basis which lacks compactness due to the leakage effect. …

System interactions and design considerations for distributed power systems
… considerations for distributed power systems (DPS) are addressed. A generalized analysis of subsystem interaction is presented. Emphasis is placed on absolute stability and eigenvalue location of the integrated system. Terminal properties of the decoupled subsystems are used in determining the …

An examination of the underlying trait structure of psychopathy: applications for screening and measurement
… Informant-report Deviant Personality Screen (DPS) is introduced and a series of empirical studies are conducted to examine the psychometric properties and construct validity of these measures in general and offender populations. Findings from these studies provide strong support for the …

Varieties of clausal complementation
… First, it is constrained by syntactic category: DPs, but crucially not CPs, are eligible for promotion, and I argue that clauses in subject position are in fact DPs. Second, it constrained by locality: even among DPs, only the highest DP is eligible for promotion. I explore a range of cases where …

The Effects of Stable and Unstable Training Surfaces on Dynamic Postural Stability
Context: Dynamic postural stability (DPS) is essential for skilled athletic performance, injury prevention, and rehabilitation. However, there is limited research on whether DPS training on unstable or stable surfaces elicit greater DPS improvements. Objective: To determine whether training on …

Use of axiomatic design principles to develop vehicle suspension controls for variable stiffness and ride height
… Requirements (FRs) and the Design Parameters (DPs). The ultimate goal is the design of a fully independent suspension system in which the FRs stiffness, ride height, and damping can be varied as needed. To achieve the three FRs, three DPs are chosen - the volume of an air spring for stiffness, …

Accelerating dynamic programming
… repeats requires a new DP, and often different DPs for different compression schemes. We present the first provable speedup of the celebrated Viterbi algorithm (1967) that is used for the decoding and training of Hidden Markov Models (HMMs). Our speedup relies on the compression of the HMM's …

A roadmap for decomposition : activities, theories, and tools for system design
… In decomposition, FRs satisfied by conceptual DPs are reduced into sets of sub-FRs. This activity is repeated until the design is completely embodied as a physical system of hardware and/ or software. A question asked about decomposition concerns consistency: How can decisions about sub-FRs, …
