Robotic Fish Mimics Escape Mechanism at Breakneck Speed

When a pike is attacked, the fish escapes by performing a lightning-fast jackknife, which generates a remarkable 25 Gs of acceleration for a tenth of a second – more than three times the acceleration of an Apollo launch. In order to study this amazing reflex action, Dr. Yahya Modarres-Sadeghi of the University of Massachusetts Amherst Mechanical and Industrial Engineering Department has spent the past two years working on two generations of robotic fish, which mimic the escape mechanism of a pike.

VISTAGY Donates 10 Software Licenses

VISTAGY, Inc., a leading global provider of industry-specific engineering software and services, has partnered with the UMass College of Engineering through the donation of 10 software licenses for the company’s FiberSIM® software. The licenses represent very sophisticated and specific software for computer aided design used to model carbon-fiber analysis. VISTAGY also donated one license of its FiberSIM® software to the college last year.

Arbella Ribbon Cutting Draws Flock of Reporters

Among the media that covered the ribbon-cutting ceremony for the newly named Arbella Insurance Group Human Performance Laboratory on December 10 were the Springfield Republican, TV stations WSHM-TV 3 and WWLP-TV 22, and radio stations WFCR and WAMC. The laboratory’s new name celebrates a recent $150,000 gift from the Arbella Insurance Foundation, the philanthropic branch of the Arbella Insurance Group (CEO John Donohue pictured).

Engineers Study Drug Dosage Protocol for Dialysis Patients

Anyone on dialysis knows the ravages of uncontrolled anemia: severe fatigue, hospitalization, and, in extreme cases, death. Now a team from the University of Massachusetts Amherst is collaborating with a leading kidney specialist at Baystate Medical Center in Springfield, Mass., to design more effective protocols for dosing a key drug used for controlling anemia in dialysis patients. In dialysis patients the amount of the hormone erythropoietin, or EPO, produced by kidneys to manage the production of red blood cells and control anemia is significantly lower than in healthy persons, resulting in the diminished red blood cell production that characterizes anemia.
