PURPOSE OF THE STUDY Older adults often have problems finding their way in novel environments such as senior living residences and hospitals. The purpose of this study was to examine the types of self-reported search strategies and cues that older adults use to find their way in a virtual maze. DESIGN AND METHODS Healthy, independently living older adults (n = 129) aged 55-96 were tested in a...

he future of healthcare delivery systems will depend on heir ability to provide the best care at the least cost. In he clinical laboratory, this translates to ensuring that lecreased test use means appropriate use. The latter is nhikely to occur unless clinical laboratories provide practicing physicians with advice on test strategy and iterpretation of results. Effective clinical laboratory con...

Testing is the process of stimulating a system with inputs in order to reveal hidden parts of the system state. We consider a variant of the testing problem that was put forward in the model-based diagnosis literature, and consists of finding input patterns that definitely discriminate between different constraint-based system models. We show that this problem can be framed as a game played bet...

in this paper a comprehensive approach is presented to improve power swings damping based on direct lyapunov method. the approach combines superconducting magnetic energy storage (smes) system with static synchronous compensator (statcom). considering the energy absorption/injection ability of smes, in transient states the combination exchanges both active and reactive powers with power system....

The purpose of this paper is to show that for a dense G set of three smooth convex bodies with nowhere vanishing curvature in the C topology k the open billiard obtained from these convex bod ies determines a potential the one that de nes the natural escape measure of this billiard which is non lattice This result generalizes one of the results obtained in a previous work of A Lopes and R Marka...

Scholars have been investigating the quick emergence of digital platforms, essentially through the lens of digital native firms. If there is limited occurrence of platforms launched by incumbent firms such as Daimler (Car2Go, Moovel) or Johnson Controls (Panopix), the economics of their strategic responses through platforms by incumbents merit attention. This paper provides the first largescale...

aces in the audience on the 25th of January! "How to win a house job" is not a subject to which there is a short answer, but rather one in which the importance lies ln the summation of a lot of minor points plus a few more major and more definite ?nes, so I shall give a general factual background and then some more detailed advice. The factual background I decided to obtain from a questionnaire...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...
