Time-Based Coordinated Checkpointing
A large number of checkpoint-based recovery protocols have been proposed in the literature, however, most of them were never evaluated. The thesis describes the design and implementation of a run-time system for clusters of workstations that allows the rapid testing of checkpoint protocols with …

Time-based low dropout regulator
… have worse performance metrics. Therefore, a time-based LDO is proposed to combine the merits of both analog and digital together. In the end, the LDO achieves 0.6-1 V supply voltage range and 0.5-0.9 V output voltage range. The maximum output current is 50 mA and the worst case transient time …

TIME-BASED CONSIDERATION IN CUSTOMER-VENDOR MODELLING
Time-based consideration in customer-vendor relationship is studied. We derived the business proportions that a customer would allocate to vendors in explicit recognition of their delivery frequencies and prices charged. We also studied the quotation of both delivery rates and prices of goods from …

Reinforcement? Time-based contingencies control local choice
… food ratio changed systematically according to time since the last food delivery from any key. In the experiment reported in Chapter 3, the relative frequency of food deliveries for responding on the two alternatives reversed at a fixed time after the most recent food delivery from any key. …

Time-Based Work-Family Conflict: Myth or Reality?
<p>The present study examined a time-based model of work-family conflict for a sample of 176 working women with childcare responsibilities. Building on the work of Edwards and Rothbard (2000) and role theory, a model was proposed to test the specific variables that define time-based work-family …

Phase-locked loop using time-based integral control
This thesis explores the time-based techniques in the context of phase-locked loop (PLL) implementation. Many studies of the topic have been performed in the past. Functioning as an effective replacement of passive capacitors, time-based integrators using oscillators prove to be more area efficient …

Time-based strategies for semiconductor manufacture and test
… is a more competitive place than before, and time is a key component in any winning competitive strategy. This thesis provides methods by which companies can become more efficient time-based competitors in the semiconductor and computer businesses. Methods are presented in two very important …

A wide-dynamic-range time-based CMOS imager
This thesis describes a novel dual-threshold time-based current sensing algorithm suitable for use in wide-dynamic-range CMOS imagers. A prototype 150 x 256 pixel imager employing this algorithm experimentally achieves 95.5 dB dynamic range, 37 dB peak signal-to-noise ratio (SNR), and a …

A time-based computer controlled dry kiln system
… using two variations of a drying schedule based upon a standard 4/4 red oak drying schedule (T4D2). Time was the controlling variable for the system. In run A, the lumber samples were dried using eight large step changes in temperature and relative humidity. In run B, a similar charge was …

Implementing time based manufacturing practices in pharmaceutical preparation manufacturers. Improving time-based manufacturing practices and enhancing manufacturing performance through action research.
… their manufacturing systems by implementing time-based manufacturing (TBM) practices. Following the diagnosis phase, the situation of each Company was analysed and suitable improvement interventions were selected for implementation in the Case Companies. At the end of the action research …

Archival time-based media : topologies of preservation and access
The analog time-based media of film, videotape, grooved sound recordings and audiotape have emerged as a growing area of concern for cultural institutions. Collectively, these media constitute a rich body of historical evidence and intangible cultural heritage whose varied physical and …

Eastern European Time-Based Art During and After Communism
… as a common platform from which to discuss time-based art practices in Eastern Europe while, on the other, it proposes that such a general view is worthless since it does not pay sufficient attention to the particular conditions within each bloc country. While the former serves as a …

Time-Based Collision Risk Modeling for Air Traffic Management
… the currency of collision risk management is time.</p> <p>Future Air Traffic Management Systems are being designed around the foundational principle of four dimensional trajectory based operations, a method that replaces legacy first-come, first-served sequencing priorities with time-based …

Time-based control techniques for integrated DC-DC conversion
Time-based control techniques for the design of high switching frequency buck converters are presented. Using time as the processing variable, the proposed controller operates with CMOS-level digital-like signals but without adding any quantization error. A ring oscillator is used as an integrator …

Flash analog-to-digital converters with time-based techniques
… high power consumption. This thesis investigates time-based techniques that enhance the performance of a flash ADC at giga-sample-per-second (GS/s) sampling rate. Two major design challenges are addressed in this thesis. The first challenge is the ever-growing comparator offset with the scaling of …

A time-based energy-efficient analog-to-digital converter
Dual-slope converters use time to perform analog-to-digital conversion but require 2N+1 clock cycles to achieve N bits of precision. We describe a novel algorithm that also uses time to perform analog-to-digital conversion but requires 5N clock cycles to achieve N bits of precision via a successive …

Time-Based Manufacturing System Design for Softwood Lumber Production
… competition. Through decreasing product lead time, U.S. manufacturers can achieve a sustainable competitive advantage. Southern yellow pine manufacturing is an example of an industry that can benefit from product lead time reduction. This project involved a case study of a southern yellow pine …

Time-based circuits for communication systems in advanced CMOS technology
… consumption of digital circuits. As a result, time-based signal processing has been attracting attention because time-based circuits take advantage of high speed and low power devices to deal with analog information in the time domain. In this thesis, we focus on a ring oscillator as a core …

Pedagogy of the fourth wall : toward a time-based architecture
… architects that can operate effectively within time-based global crises. In their attempts to address issues of sustainability and resiliency, architects have trapped themselves in a false binary, understanding structures to be either temporary or permanent. However, this considers only …
