Here we update and expand our previous work to find commonality in a variety of systems, situations, and organisms with regard to a generic concept of complexity (1). Such attempts have drawn significant attention from outstanding researchers of diverse backgrounds (2). Despite years of research with many papers written, there is yet to appear a convergence toward a unified methodology in the m...

Designers of automatic target recognizers (ATR) need measures of image complexity to compare the performance of different ATRs. An image complexity metric should provide an a priori estimate of the difficulty of locating a true target in an image. An ideal image metric is a mapping from the set of all images to a finite real interval. The extrema of the interval indicate extrema in difficulty. ...

We examine the use of read-time feature conditionals, with particular emphasis on writing portable Common Lisp code which aspires to both forwardsand backwards-compatibility. We examine cases from real libraries which demonstrate the various pitfalls, and propose a scheme for robust treatment of implementation-specific functionality by performing programmatic tests at the appropriate time. We d...

Educational research on emerging technologies, particularly virtual reality and augmented reality, is expanding at the moment. The purpose of this contribution to conduct a systematic review understand impact technologies in educational social-health fields. PRISMA 2020 methodology was used respond objective questions, ensuring fulfillment quality criteria elaboration review. This analyses poss...

Asking which sets are fixed-parameter tractable for a given parameterization constitutes much of the current research in parameterized complexity theory. This approach faces some of the core difficulties in complexity theory. By focussing instead on the parameterizations that make a given set fixed-parameter tractable, we circumvent these difficulties. We isolate parameterizations as independen...
