Can Alzheimer’s Disease Be Prevented?

A recent study in The Lancet Neurology Journal suggests that one third of worldwide Alzheimer’s cases could be prevented.

Alzheimer’s disease is the most prevalent form of dementia, a general term for conditions that affect mental ability. “Dementia” means that two or more core mental functions are impaired:

Communication and language
Agility to focus and pay attention
Reasoning and judgment
Visual perception

Alzheimer’s accounts for 60 to 80 percent of dementia cases. (The second most frequent dementia is vascular dementia, which occurs following a stroke).

Cambridge researchers found that one third of Alzheimer’s cases result from risk factors that can be modified. These …read more

This comes after previous medical studies linked the diarrheal disease to infected United Nations peacekeepers not only in its Haitian mission, but at least others in Africa and the Middle East.

In the report that was withheld for nearly a year, United Nations auditors found that peacekeepers and their supervisor were either unaware or careless about enforcing protocols for wastewater, …read more

At times, cleaners must work in the aftermath of bloody homicides. Other times, they may be digging through the unsteady towers of possessions in …read more

Untethered from San Francisco to Boston: Intel’s Project Alloy and MBTA Mechanics Get New Eyes

IDF 2016 – San Francisco
This city is probably best known for gold-mining, Joe Montana, earthquakes, Robin Williams, hippies, Steph Curry and tech-induced rapid-fire gentrification. Cultural fluctuations and pop culture icons aside, last week saw the late Andy Grove’s legendary processor company Intel put on Intel Developer Forum (IDF) 2016, where it made some big announcements in the “mixed reality” space. Mixed reality is a term that encompasses both virtual reality (VR) and augme… …read more

Tracy-Widom Approach to F16 Aircraft Sensor-Actuator Fault Detection


The post Tracy-Widom Approach to F16 Aircraft Sensor-Actuator Fault Detection first appeared on the ISA Interchange blog site.

This post is an excerpt from the journal ISA Transactions. All ISA Transactions articles are free to ISA members, or can be purchased from Elsevier Press.

Abstract: The fault detection approach based on the Tracy-Widom distribution is presented and applied to the aircraft flight control system. An operative method of testing the innovation covariance of the Kalman filter is proposed. The maximal eigenvalue of the random Wishart matrix is used as the monitoring …read more
