Traitor tracing is needed because some users in broadcast encryption system may give out their decryption keys to construct pirate decoders. Recently, Liu and Yuan described a trace and revoke systems with short ciphertexts. In this paper, we show that their scheme cannot achieve traitor tracing, since any receiver can decide whether the given ciphertext is well-formed or not so as to decide wh...

Requirements tracing is inevitable. We do tracing when we search information and it is difficult to imagine a software development environment without some tracing aids. For medium to complex systems we should have a traceability model and traceability aids should be in place. In these systems we have a quite complex web of relationships. It is common to have several requirements coming from th...

Automatic interpretation of Transmission Electron Micrograph (TEM) volumes is central to advancing current understanding of neural circuitry. In the context of TEM image analysis, tracing 3D neuronal structures is a significant problem. This work proposes a new model using the conditional random field (CRF) framework with higher order potentials for tracing multiple neuronal structures in 3D. T...

Ray-tracing techniques for image rendering have produced some of the most realistic images to date. They are also slow because the process of tracing a ray is computationally intensive and because there are many rays to be traced. However. since computations for each pixel are independent, ray tracing is amenable t o parallel processing uslng image space subdivision. The processor per subdivisi...

This paper presents a workflow validation method for data-intensive graphical workflow models using real-time workflow tracing mode on data-intensiveworkflow designer. In order to model and validate workflows, we try to divide as modes have editable mode and tracingmode on data-intensiveworkflow designer. We could design data-intensive workflow using drag and drop in editable-mode, otherwise we...

Unlike device-centric monitoring, task-centric tracing enables an operator to causally trace the complete execution of a networked system across the boundaries of applications, protocols, and administrative domains. In this paper, we argue that causal, end-to-end tracing should be an integral part of network services. Moreover, it is not fundamentally difficult to achieve, given a primitive tha...

BACKGROUND Universal HIV testing/treatment program has currently been suggested and debated as a useful strategy for elimination of HIV epidemic in Africa, although not without practical issues regarding the costs and feasibility of a fully implemented program. METHODS A mathematical model is proposed which considers two levels of detection of HIV-infectives through contact tracing of known i...

Carbocyanines (DiI, DiA, DiO) are able to travel along membranes by diffusion and therefore have been used as postmortem neuronal tracers in aldehyde-fixed tissues. Surprisingly, detailed data on the influence of different parameters on tracing distances are still missing. This study was carried out to optimize tracing procedures and to reveal the validity of the combination of postmortem traci...

A scheme for building a decision model of short-term liquidity analysis from domain experts is presented, which combines the features of both process tracing approach and output analysis approach. The scheme consists of process tracing, output analysis, and model review component. The process tracing component applies the Concurrent Verbal Protocol Analysis to build an initial decision model by...
