In this paper, a set of heuristics for evaluating the usability of mobile map applications is introduced. We developed the heuristics by exploring the present generic heuristics and then forming new theory-based heuristics. Usability specialists tested the heuristics by evaluating the usability of a mobile map application with both generic and domain-specific heuristics. As a result, more usabi...

We investigate the feasibility of applying the principles of domain-specific modeling to the problem of capturing and preservation architectural modeling knowledge. The proposed solution is based on the existing architecture assessment methods, rather than architecture modeling ones, and it uses sequences of design decisions, rather than simple, unordered sets. We highlight how architecture-bas...

The ability to identify novel patterns in observations is an essential aspect of intelligence. In a computational framework, the notion of a pattern can be formalized as a program that uses regularities in observations to store them in a compact form, called a compressor. The search for interesting patterns can then be stated as a search to better compress the history of observations. This pape...

In this paper the problem of learning appropriate domain-specific bias is addressed. It is shown that this can be achieved by learning many related tasks from the same domain, and a theorem is given bounding the number tasks that must be learnt. A corollary of the theorem is that if the tasks are known to possess a common internal representation or preprocessing then the number of examples requ...

We examine phylogenetic relationships among salamanders of the family Salamandridae using approximately 2700 bases of new mtDNA sequence data (the tRNALeu, ND1, tRNAIle, tRNAGln, tRNAMet, ND2, tRNATrp, tRNAAla, tRNAAsn, tRNACys, tRNATyr, and COI genes and the origin for light-strand replication) collected from 96 individuals representing 61 of the 66 recognized salamandrid species and outgroups...

A 13.4 kb rat genomic DNA fragment containing two related tRNA gene clusters was isolated from a rat lambda recombinant and analyzed for gene arrangement and nucleotide sequence. One cluster was found to contain a tRNALeuCUG gene while the second contained a tRNALeuCUA pseudogene with multiple base substitutions. The tRNALeu gene was found to possess an intact coding region and a functional tra...

Cloned tRNA genes from Drosophila and from yeast have been transcribed faithfully in extracts prepared from Xenopus germinal vesicles. The newly formed RNA is composed of precursor tRNAs (of 5S RNA size) and of tRNAs. The plasmid pCIT12 carries genes for Drosophila tRNALys, tRNAArg, and tRNAAsn, Nucleotide analysis of one RNA species transcribed from pCIT12 DNA showed it to be identical to Dros...
