Global Optimization Of Some Difficult Benchmark Functions By Cuckoo-Host Co-Evolution Meta-Heuristics, Sudhanshu K. Mishra
Global Optimization Of Some Difficult Benchmark Functions By Cuckoo-Host Co-Evolution Meta-Heuristics, Sudhanshu K. Mishra
Sudhanshu K Mishra
This paper proposes a novel method of global optimization based on cuckoo-host co-evaluation. It also develops a Fortran-77 code for the algorithm. The algorithm has been tested on 96 benchmark functions (of which the results of 32 relatively harder problems have been reported). The proposed method is comparable to the Differential Evolution method of global optimization.

Multi-Tier Exploration Concept Demonstration Mission, Jeremy Straub
Multi-Tier Exploration Concept Demonstration Mission, Jeremy Straub
Jeremy Straub
A multi-tier, multi-craft mission architecture has been proposed but, despite its apparent promise, limited use and testing of the architecture has been conducted. This paper proposes and details a mission concept and its implementation for testing this architecture in the terrestrial environment. It is expected that this testing will allow significant refinement of the proposed architecture as well as providing data on its suitability for use in both terrestrial and extra-terrestrial applications. Logistical and technical challenges with this testing are discussed.
Imagining Emergent Metadata, Realizing The Emergent Web, Jason A. Bengtson
Imagining Emergent Metadata, Realizing The Emergent Web, Jason A. Bengtson
Jason A Bengtson
Current metadata schemas are largely analog technology grafted onto the digital format. They have three inherent limitations that need to be transcended: they generate a static product which must be changed manually, they revolve around the needs of human, rather than mechanistic agents, and they are limited by the imagination and organizational capabilities of human agency. The author argues that to meet future challenges metadata will have to take a more flexible, adaptive form that centers on the needs of the machine in searching, interpretation and organization until the information it proxies enters into the human sphere. The author further …

The Art Of Redirection: Putting Mobile Devices Where You Want Them, Jason A. Bengtson
Jason A Bengtson
Mobile technology has exploded, with many libraries experiencing a surge in access to their resources through mobile devices. In response, many institutions have created or are creating mobile sites designed to accommodate themselves to the unique strictures of these devices. One hurdle faced by these organizations, however, is getting mobile users to those sites. One solution is mobile redirect scripts, which automatically redirect mobile users from a regular page to a mobile page. These scripts come in various forms and present unique challenges to libraries. How are these scripts created? What triggers can or should be used to activate them? …

Improving The Relevancy Of Document Search Using The Multi-Term Adjacency Keyword-Order Model, Ram Gopal Raj
Improving The Relevancy Of Document Search Using The Multi-Term Adjacency Keyword-Order Model, Ram Gopal Raj
Ram Gopal Raj
This paper presents an enhanced vector space model, Multi-Term Adjacency Keyword-Order Model, to improve the relevancy of search results, specifically document search. Our model is based on the concept of keyword grouping. The keyword-order relationship in the adjacency terms is taken into consideration in measuring a term’s weight. Assigning more weights to adjacency terms in a query order results in the document vector being moved closer to the query vector, and hence increases the relevancy between the two vectors and thus eventually results in documents with better relevancy being retrieved. The performance of our model is measured based on precision …
Automated Web Based System For Bone Age Assessment Using Historam Technique, Ram Gopal Raj
Automated Web Based System For Bone Age Assessment Using Historam Technique, Ram Gopal Raj
Ram Gopal Raj
Bone age assessment (BAA) is often used to evaluate the growth status of children as part of the detection of hormonal problems and genetic disorders. The determination of skeletal maturity is done based on a radiological examination of the hand-wrist skeletal area.This paper introduces a novel approach for BAA that utilizes a histogram based comparison technique. This approach is executed as a web based system that uses an image repository and similarity measures based on content-based image retrieval. This study aims to overcome to the limitations of traditional methods utilized to estimate human age which were often imprecise.The system provides …

Nowadays discourse parsing is a very prominent research topic. However, there is not a discourse parser for Spanish texts. The first stage in order to develop this tool is discourse segmentation. In this work, we present DiSeg, the first discourse segmenter for Spanish, which uses the framework of Rhetorical Struc- ture Theory and is based on lexical and syntactic rules. We describe the system and we evaluate its per- formance against a gold standard corpus, divided in a medical and a terminological subcorpus. We obtain promising results, which means that discourse segmentation is possible using shallow parsing.
