Hazard detection with VHDL in combinational logic circuits with fixed delays
Timing hazards are common problems found in logic circuits. A new integrated hazard detection system (HDS), which is implemented in VHDL, is proposed to detect the static, the dynamic, and the function hazards in any logic circuit that is described structurally in VHDL. This system adopts the IEEE …

Automatic back annotation of timing into VHDL behavioral models
… of VHDL behavioral models with back annotated timing. The behavioral model is developed using the CAD tool called Modeler's Assistant by inputting the model in the form of a Process Model Graph. Then using the built-in primitive process library and user responses the Modeler's Assistant …

A search for slow, lightly ionizing particles in cosmic rays
… operated without a trigger and used interplanar timing information to identify potential events, and operated above a threshold of 1/400 of that of a minimum ionizing muon.

MECHANISMS OF GAZE STABILITY DURING WALKING: BEHAVIORAL AND PHYSIOLOGICAL MEASURES RELATING GAZE STABILITY TO OSCILLOPSIA
… which may allow for more accurate use of visual information. This dissertation reports the findings of five experiments which explore how the nervous system uses vision to control upright posture during walking and also whether the act of walking contributes to gaze stability for individuals with …

Analysis of return oriented programming and countermeasures
… 1. Show how code reuse attacks can leverage timing information in order to break many existing defenses. 2. Investigate how control flow integrity can be improved upon as a countermeasure to code reuse attacks ...

Predicting execution behavior for codesign synthesis using static analysis
… dependence of the input program and predicts its timing behavior using two different approaches. The tool can be integrated into a compiler for a custom computing machine for codesign synthesis. The timing information can be used effectively by the code optimizer to identify portions of the code …

A Pointillism Approach for Natural Language Processing of Social Media
… aspect of the Pointillism approach. Detailed timing information, such as timestamps of when posts were posted, contain correlations based on human patterns and current events. This timing information provides the necessary context to build words and phrases out of trigrams and then group those …

A combined clustering and placement algorithm for FPGAs
… thesis presents a novel algorithm to improve timing performance at the possible expense of area and runtime. The algorithm presented leverages node duplication and a depth-optimal initial clustering to provide a starting point for a non-greedy, iterative optimization technique using detailed …

Economical sampling of parametric signals
… white Gaussian noise. We focus on estimating the timing information in signals that are linear combinations of scales and shifts of a known pulse. This signal model is well-known in a variety of disciplines such as ultra-wideband signaling, neurobiology, etc. The signal is completely determined by …

CMOS circuits for VCSEL-based optical IO
… dynamics of the VCSEL. The driver derives timing information directly from the full-rate input data and generates pre-emphasis pulses with width resolution less than one bit period in a manner that is compatible with full-rate IO architectures.

Defending against side-channel attacks : DynamoREA
Modern computer architectures are prone to leak information about their applications through side-channels caused by micro-architectural side-effects. Through these side-channels, attackers can launch timing attacks by observing how long an application takes to execute and using this timing …

Performance-driven chip floorplanning and global routing
… incorporated into the problem formulations. A timing analysis provides timing information consisting of a set of potentially critical paths and the delay slacks of the signal nets. This information is used to maintain path delays within bounds and to minimize the delay of the most critical …

Amplitude sampling for signal representation
… sampling with either assuming infinite-precision timing information or time restricted to a uniform grid. If time is allowed to lie on the continuum, the approach is based on a structure that is equivalent to reversibly transforming the input signal into a monotonic function which is then …

Flash analog-to-digital converters with time-based techniques
… we propose an offset calibration method based on timing skew. The proposed method does not add any extra load to the comparator, avoiding the penalties of conventional methods. The second challenge is the exponentially growing number of comparators with resolution. This thesis proposes a …

Robust decision-support tools for airport surface traffic
… Airport. The Lufthansa dataset includes detailed timing information on all of the turn processes, including deboarding, catering, cleaning, fueling and boarding. The dataset is carefully filtered to obtain a sample of 3820 minimum-uncertainty ground events. The forecast models and techniques are …

PLL-based active optical clock distribution
Reducing the timing uncertainty associated with clock edges has become an exceedingly difficult problem as clock frequencies in high-performance processors increase past several gigahertz. Absolute quantities of skew and jitter that were insignificant at lower frequencies now consume an …

A personal, mobile system for understanding stress and interruptions
… applications are designed to monitor sensed information about a person's physiological signals over time. Such applications include systems for tracking heart conditions that have been in use by cardiologists for decades to recent prototypes for monitoring elders in cognitive decline. This …
