Given a set of weighted objects in a data space, the MaxRS problem in spatial databases studied in a VLDB 2012 paper is to find a location for a rectangular region of a given size such that the weighted sum of all the objects covered by the rectangular region centered at the optimal location is maximized. This problem is useful in lots of location-based service applications, such as finding the...

This paper describes an approach to the feature location problem for distributed systems, that is, to the problem of locating which code components are important in providing a particular feature for an end user. A feature is located by observing system execution and noting time intervals in which it is active. Traces of execution in intervals with and without the feature are compared. Earlier ...

MATRAS is a newly proposed traffic monitoring and controlling model based on the Multi-Agent System. Indian Railways has a huge, robust and extremely complex network which is the largest in the World. But we are still practicing very traditional approaches in the Indian Railways, which requires frequent human interventions. As a result, any sort of mistake or deliberation could lead us to a fat...

The design of a CBR system involves the use of similarity metrics. For many applications, various functions can be adopted to compare case features and to aggregate them into a global similarity measure. Given the availability of multiple similarity metrics, the designer is hence left with two options in order to come up with a working system: Either select one similarity metric or try to combi...

In most ranking systems for information retrieval, there are multiple signals that need to be combined to generate a single score for ranking a result. In this work we consider how the output score of various ranking systems can be combined to rank the TREC 2003 and 2004 benchmark datasets. Not surprisingly, we find that the performance of a combined system is able to achieve significantly bett...

abstract. a practical common weight scalarizing function methodology with an improved discriminating power for technology selection is introduced. the proposed scalarizing function methodology enables the evaluation of the relative efficiency of decision-making units (dmus) with respect to multiple outputs and a single exact input with common weights. its robustness and discriminating power are...

based on the randic suggestion of the resolution of a structure into shape, size, and function an index representing structure-catabolic fate relationships of amino acids is constructed. the index obtained by multiplying three factors; (nb2 + nr), nc and m; representing shape, size and function respectively, where nb2 = number of double bonds, nr = number of rings, nc = number of carbon atoms, ...

the logistic, gompertz, richards and asymmetric logistic growth curve models were fitted to body weight data of local ghanaian chickens and french sasso t44 chickens. all four growth models provided good fit for each sex by genotype growth data with r2 values ranging from 86.7% to 96.7%. the rate constant parameter, k, ranged between 0.137 and 0.271 and were significantly different from zero fo...
