Abstract We describe in dialogue form a possible way of discovering and investigating 10-adic numbers starting from the naive question about “largest natural number”. Among topics we pursue are possibilities extensions to transfinite numbers, representations rational zero divisors, square roots higher degree applications number representation computer arithmetic. The participants idealized embo...

Current approaches to social search are generally based on the friends’ opinion and collaborative filtering paradigms, which have limited effectiveness in terms of both accuracy and coverage of the information that may be relevant to a user. We propose a new kind of social search signal, based on the idea of prediction extraction, which is aimed at improving the quality of information available...

Background: Work-related musculoskeletal disorders are major causes of absenteeism, increased costs, and human injuries among computer users. This study aimed to examine the effects of ergonomics training and corrective exercises on musculoskeletal disorders among a gas company computer users. Material and Methods: This experimental study was conducted on 19 office computer users who participa...

Although the current computer-aided design (CAD) and computer network technologies have laid the foundation for the emerging fields of computer supported cooperative work (CSCW) in multidisciplinary design, the heterogeneity of multidisciplinary design knowledge representation is still a major obstacle to sharing and exchanging multidisciplinary design knowledge for multidisciplinary collaborat...

In the early 1990s, after more than three decades of studying algorithms within the frame work of theoretical computer science, I shifted my focus to alogrithmic problems arising in genomics. There is a fundamental difference between the views of algorithms in the two fields: in theoretical computer science the input-output behavior of an algorithm is rigorously specified in advance, whereas in...

Chaitin [G. 1975] introduced Ω number as a concrete example of random real. The real Ω is defined as the probability that an optimal computer halts, where the optimal computer is a universal decoding algorithm used to define the notion of program-size complexity. Chaitin showed Ω to be random by discovering the property that the first n bits of the base-two expansion of Ω solve the halting prob...

The ultimate purpose of many medical data mining systems is to create formalized knowledge for a computer-aided diagnostic system, which can in turn, provide a second diagnostic opinion. Such systems should be consistent and complete as much as possible. The system is consistent if it is free of contradictions (between rules in a computer-aided diagnostic system, rules used by an experienced me...

Chaitin [G. J. Chaitin, J. Assoc. Comput. Mach., vol. 22, pp. 329–340, 1975] introduced Ω number as a concrete example of random real. The real Ω is defined as the probability that an optimal computer halts, where the optimal computer is a universal decoding algorithm used to define the notion of program-size complexity. Chaitin showed Ω to be random by discovering the property that the first n...
