It is a widely accepted premise of industrial management that an
interruption in the performance of a task will be accompanied by a
decrease in operator skill level upon resuming performance of the
task. Moreover, it has been generally assumed that this loss of
skill is related to several factors...
The objective of this research was to investigate
the physiological effects of body posture on cycling.
The familiar positions of bicycle riding have been the
touring posture (hands stretched on top handlebar) and
the racing posture (hands bent at the elbow, with the
back horizontal). However, a relatively new stance...
This dissertation describes the development of a mechanistic
overlay design procedure. The mechanistic analysis represents a new
trend in both new pavement and overlay design. The greatest advantage
of the mechanistic pavement analysis is that it considers the
fundamental characteristics of materials to be used, is capable of
considering changes...
Job aids are instruments used on the job to improve
human performance by enhancing the knowledge and/or skills
of performers. Conventional job aids are usually printed
on paper; examples include checklists, recipes, and decision
tables.
Expert systems are computerized job aids which interact
with novices to help solve problems normally...
A prototype real-time process monitoring emergency
classification expert system, RT/EM-CLASS, has been developed
for use at the Trojan Nuclear Power Plant. This knowledge-based
system features the integration of electronically sensed plant
data with the menu selection data representation of its
predecessor, EM-CLASS. This prototype demonstrates the
techniques required to acquire...
With the passage of the American with Disabilities Act (ADA) it has become a civil
rights violation to deny access to persons with disabilities to public transportation. The
ADA requires transit agencies to provide accessible buses or equivalent services to
persons with mobility, sensory or cognitive impairments. This study examines...
Flexible Manufacturing Systems (FMSs) have evolved rapidly over the last decade. One important factor that influences the performance of FMS is scheduling. Scheduling in an FMS differs from that in a conventional job-shop because each operation of a job may be performed by any one of several machines. Most studies...
Cellular Manufacturing Systems (CMS) have claimed many advantages over traditional job shop processes. Some of the advantages reported by several users of CMS are reduction in throughput time, reduction in WIP inventory, improvement in product quality, faster response time to customer orders, shorter move distances, increase in manufacturing flexibility, and...
Juvenile chinook salmon (Oncorhynchus tshawytscha) were experimentally infected with Renibacterium salmoninarum (Rs), the causative agent of bacterial kidney disease (BKD), to investigate the effects of BKD on three aspects of juvenile salmonid performance: (1) predator avoidance ability; (2) smoltification; and (3) physiological responses to stress. For these experiments, fish with...
The use of mobile bar code scanners is expanding to markets beyond popular manufacturing uses, such as healthcare, environmental testing and professional services. The successful interaction of users with mobile bar code scanners is of great importance from a business and technology perspective as well as from the user standpoint....
