A Similarity Measure for Large Color Differencesnmoroney
Hundreds of large color differences, of magnitude 20 DeltaE00, were generated and used in a visual sorting experiment. The process of generating these color differences and two specific experiments are described in detail. The results show that small color difference metrics, such as DeltaE00, do not consistently model the visually sorted differences for large differences. A new similarity measure, based on a cosine similarity between categorical vectors of colors, is described and used to more consistently model large color differences. This similarity metric can be used to better characterize large color errors during reproduction, for image processing operations such as segmentation or as a feature for content retrieval. The new measure can also be applied to visual phenomena, such as categorical perception, in which within category color differences are perceived as smaller than across category differences.
Efficient Memory-Reference Checks for Real-time JavaAngelo Corsaro
The scoped-memory feature is central to the Real-Time Specifica- tion for Java. It allows greater control over memory management, in particular the deallocation of objects without the use of a garbage collector. To preserve the safety of storage references associated with Java since its inception, the use of scoped memory is con- strained by a set of rules in the specification. While a program’s adherence to the rules can be partially checked at compile-time, un- decidability issues imply that some—perhaps, many—checks may be required at run-time. Poor implementations of those run-time checks could adversely affect overall performance and predictabil- ity, the latter being a founding principle of the specification.
In this paper we present efficient algorithms for managing scoped memories and the checks they impose on programs. Implementa- tions and results published to date require time linear in the depth of scope nesting; our algorithms operate in constant time. We de- scribe our approach and present experiments quantifying the gains in efficiency.
This presentation provides an overview of the Innovation Model adopted for OpenSplice DDS and then goes on presenting the standardization and development Roadmap as well as the set of Technology Incubators that we are trying to sparkle around OpenSplice DDS.
This presentation introduces dscript, a framework that brings DDS-like publish/subscribe to the Web Browser. Beyond providing an inter-browser Pub/Sub abstraction, dscript provides with a semaless integratio with native DDS applications. Meaning that data can flow effortlessly from native DDS applications to the browser and viceversa.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
