Can CLI be trusted?

Calling Line Identification (CLI) tells the recipient of a telephone call the number at the other end of the line. However, various insecurities mean that even on traditional telephone systems, CLI cannot be entirely relied upon to be accurate. Once Voice-over-IP (VoIP) enters the picture, CLI validity effectively depends upon the integrity of Internet traceability, and must therefore be treated with considerable suspicion.     

A provable secure pairing-free certificateless identification scheme

Certificateless identification (CLI) schemes offer an alternative solution to the certificate management problem of traditional identification schemes, as well as remove the key escrow from key generation, an inherent property of identity-based identification. In this paper, we provide a pairing-free CLI scheme, provable secure against passive and active/concurrent attacks for both Type-1 and Type-2 adversaries. This shows that our scheme is computationally efficient because no bilinear pairings are involved.     

A visual shell interface to a database

This paper describes a visual command language for a workstation with a bit-mapped display and a mouse that can be used to create different user interfaces. Primitive interface components can be combined into more complex user interfaces. The user specifies interconnections between these components over which data and commands can be sent by pointing with a mouse. Primitive interface components are described for creating several different database user interfaces. The design and implementation of the software architecture is described, including the primitives for database interfaces and the communication protocols used by the system.

Collective intelligence applied to legal e-discovery: A ten-year case study of Australia franchise and trademark litigation

The purpose of this research is to develop a formal knowledge e-discovery methodology, using advanced information technology and decision support analysis, to define legal case evolution based on Collective Litigation Intelligence (CLI). In this research, a decade of Australia’s retail franchise and trademark litigation cases are used as the corpus to analyze and synthesize the evolution of modern retail franchise law in Australia. The formal processes used in the legal e-discovery research include a LexisNexis search strategy to collect legal documents, text mining to find key concepts and their representing key phrases in the documents, clustering algorithms to associate the legal cases into groups, and concept lattice analysis to trace the evolutionary trends of the main groups. The case analysis discovers the fundamental issues for retail modernization, advantages and disadvantages of retail franchising systems, and the potential litigation hazards to be avoided in the Australian market. Given the growing number of legal documents in global court systems, this research provides a systematic and generalized CLI methodology to improve the efficiency and efficacy of research across international legal systems. In the context of the case study, the results demonstrate the critical importance of quickly processing and interpreting existing legal knowledge using the CLI approach. For example, a brand management company, which purchases a successful franchise in one market is under limited time constraints to evaluate the legal environment across global markets of interest. The proposed CLI methodology can be applied to derive market entry strategies to secure growth and brand expansion of a global franchise.

Command-induced vibration analysis using input shaping principles

Input shaping is a well-established technique used for reducing the vibratory response of dynamic systems. Analytical tools are available for systems utilizing input shaping. These tools aid in performance analysis by providing intuitive and computationally simple methods for determining key system attributes, such as the residual vibration in response to a command. This paper describes methods whereby arbitrary reference commands may be interpreted as input-shaped commands. This capability allows input shaping analysis tools to be used on systems without input shapers. Experimental results obtained from an industrial 10-ton bridge crane validate the theoretical developments.
