In recent years there has been considerable development in the area of system reliability assess-ments of offshore structures except for jack-up platform. However, since the reliability of jack-up platform is acrucial aspect with regard to the safety of the structure during its service time and possibly beyond the predictedlifetime, there is significant demand from the offshore indu...

Background. The injured anterior cruciate ligament (ACL) has a limited healing capacity leading to persisting instability. Hypothesis/Purpose. To study if the application of a brace, producing a dynamic posterior drawer force, after acute ACL injury reduces initial instability. Study Design. Cohort study. Methods. Patients treated with the ACL-Jack brace were compared to controls treated with p...

Koike, K., On a conjecture of Stanley on Jack symmetric functions, Discrete Mathematics 115 (1993) 211-216. The Jack symmetric function J,(x; G() is a symmetric function with interesting properties that J,(x; 2) is a spherical function of the symmetric pair (GL(n, FQ O(n, [w)) and that J,(x; 1) is the Schur function S,(x). Many interesting conjectures about the combinatorial properties of J,(x;...

Since the inception of jack-up rig operations in early 1950s, series hazardous accidents has been witnessed, and losses recorded. These events are approximated to occur at least twice a year. With this statistics, harsh offshore environment demands jack-ups premium quality. Designing self-elevating (jack-up) structure is one that must be founded on well-proven principles, industry-accepted reli...

We propose to provide a prototype of an agent-based network management system in which, unreliable agents can be detected by the other agents. The detection method is based on having the agents testing each other by comparing their respective beliefs. The agents are speciied using an abstract agent functional model. This model is based on a BDI (Belief Desire Intention)-like mental cycle and us...

Mature trees of eastern white, jack, Scotch, and shortleaf pines were inoculated with 25,000-34,000 pinewood nematodes, Bursaphelenchus xylophilus, isolated from infected Scotch pines in Missouri. Equal numbers of trees of each species inoculated with distilled water served as controls. Nine of fifteen Scotch pines died within 4 months of nematode infection or during the winter and early spring...

Agent-based models of human operators rarely include explicit representations of the timing and accuracy of perception and action, although their accuracy is sometimes implicitly modelled by including random noise for observations and actions. In many situations though, the timing and accuracy of the person’s perception and action significantly influence their overall performance on a task. Rec...

John T. (Jack) Reeves' science is reviewed across the 37 years of his research career at the University of Colorado Health Sciences Center, a period which occupied approximately half his remarkable life. His contributions centered on understanding the inter-relatedness as well as the underlying mechanisms controlling the various components of the O(2) transport system. We review here his studie...

This paper presents a simulation system which integrates a realtime hand sensing and force-feedback interface (the Rutgers Master II) with a full body modeling software (JACK ). The RM– II system and the Polhemus Fastrak 3D magnetic tracker were initially integrated with “JACK" full-body simulation software. The system performance (graphics update rates, sensor reading updates) is evaluated on ...
