Transportation Research Record: Journal of the Transportation Research Board, 2011
Hazard models are used only moderately in the transportation field compared with their levels of application in other areas, such as medicine, political science, and economics. Many specifications of the hazard models are not well known, whereas the primary application of hazard models is limited to a basic proportional continuous hazard formulation ...

Tutorial on Discrete Hazard Functions
Quality Management in Health Care, 2007Risk analysis requires estimation of hazard functions. A hazard rate is the conditional probability of adverse sentinel event occurring in the next time period, given that it has not yet occurred. This tutorial shows how hazard functions are estimated from survival functions, the probability of going through a time period without the sentinel event ...

Hazardous workspace modeling for manipulators using spatial hazard functions
2012 IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR), 2012This paper describes an approach to motion planning that includes hazards individually characterized as continuous functions of space. These functions contribute to a complex and discontinuous yet practical representation of the hazards found in a manipulator's workspace.

Hazard function estimators: a simulation study
Statistics in Medicine, 1999Kernel-based methods for the smooth, non-parametric estimation of the hazard function have received considerable attention in the statistical literature. Although the mathematical properties of the kernel-based hazard estimators have been carefully studied, their statistical properties have not.

Epidemiologia e prevenzione, 2008
In cohort studies the event occurrence is usually described by the incidence rate and the survivor function. In comparison with these estimators the plot of the hazard function has the advantage to show the variations of the occurrence of the event along the period of observation, which often are important to be highlighted. Furthermore, when comparing

March Myoglobinemia: A Hazard to Renal Function
Journal of Urology, 1983Serum muscle enzyme levels, myoglobin levels, and renal function were measured in a group of 20 army recruits who had volunteered for a prolonged period of primary, specially designed, gradual training. Blood samples were taken before training and before and after each hike. Levels of serum myoglobin, creatinine phosphokinase, lactic dehydrogenase, and

Potential Hazard of Two Functioning Pacemakers
Chest, 1972A patient with the bradycardia-tachycardia syndrome received a permanent ventricular inhibited demand pacemaker as well as a standby temporary transvenous pacemaker. When ventricular premature beats were seen, the temporary pacemaker was activated at 135 beats/min.

Hazard rate function in dynamic environment
Reliability Engineering & System Safety, 2014Abstract The hazard rate function is always applied to make maintenance policy, and the usual hazard rate function is computed by the data of failure times of systems working in constant environment, thus for systems working in dynamic environment it cannot be directly applied.
