Hands Off Yet All In

Hands-Off Spreadsheets

The wealth of functionality in the Excel software package means it can go beyond use as a static evaluator of predefined cell formulae, to be used actively in manipulating and transforming data. Due to human error it’s impossible to ensure a process like this is always error free, and frequently the sequence of actions is recorded only in the operator’s head. If done regularly by highly paid st...

All hands on deck!

Adaptive, Hands-Off Stream Mining

Sensor devices and embedded processors are becoming ubiquitous, especially in measurement and monitoring applications. Automatic discovery of patterns and trends in the large volumes of such data is of paramount importance. The combination of relatively limited resources (CPU, memory and/or communication bandwidth and power) poses some interesting challenges. We need both powerful and concise “...

Value Function in Maximum Hands-off Control

In this brief paper, we study the value function in maximum hands-off control. Maximum hands-off control, also known as sparse control, is the L-optimal control among the admissible controls. Although the L measure is discontinuous and nonconvex, we prove that the value function, or the minimum L norm of the control, is a continuous and strictly convex function of the initial state in the reach...

The management of keloids: hands-on versus hands-off.

Keloids are benign fibrous growths that appear in scar tissue. The lesions can be severely disfiguring and early recognition of genetic lesions is crucial. This case report outlines and reviews the important management strategies for these lesions and the requirement for extensive counseling for the patient and their family. Many potential medical and surgical interventions exist. Unfortunately...
