The Everstart Is a Battery with an Intended Design Life

question 52

Essay

The Everstart is a battery with an intended design life of 72 months. Stephanie Bradley recently put five of these batteries through accelerated testing (the company couldn't wait six years) to simulate failure patterns. The test results had one failure at 26 months, one failure at 32 months, one failure at 50 months, and one failure at 62 months. Calculate FR(%), FR(N), and MTBF.

Pruning Process

Neural pruning is the process by which extra neurons and synaptic connections are eliminated to increase the efficiency of neuronal transmissions.

Epigenetic Marks

Chemical modifications to DNA and histones that affect gene expression without altering the DNA sequence, often as a response to environmental factors.

Neural Maturation

The process of growth and development of the nervous system, especially in terms of complexity and efficiency of neural pathways.

Nurture

The influence of environmental factors like education, culture, and personal experiences on the growth and development of an individual.
