Résumé :

Purpose: To investigate the use of software-generated corrections in neutralizing perceived distortions in age-related macular degeneration. Methods: A tablet-based application was utilized to elicit distortions. Five subjects (seven eyes: neovascular age-related macular degeneration and three eyes: non-neovascular age-related macular degeneration) traced the reference lines, and their distortion traces were recorded. To counter distortion, a software-generated trace was re-traced by subjects to produce a corrected trace. Final traces were superimposed on optical coherence tomography images an

Résumé :

1. The work is a study in the methodological foundations of the criminalistic doctrine of traces. Before arriving by logical means to the knowledge of general classification criteria and to the classification of the trace itself, the author had to resolve the meaning of the term trace. He reached it not only by comparing the existing knowledge of the criminalistic theory, but above all by making thorough use of the Marxist theory of methodology, in particular of the Leninist reflection theory. In examining the problems under review, the author pursued the knowledge and elaboration of one of th

Résumé :

AbstractTracers provide users with useful information about program executions. In this article, we propose a “tracer driver”. From a single tracer, it provides a powerful front-end enabling multiple dynamic analysis tools to be easily implemented, while limiting the overhead of the trace generation. The relevant execution events are specified by flexible event patterns and a large variety of trace data can be given either systematically or “on demand”. The proposed tracer driver has been designed in the context of constraint logic programming (CLP); experiments have been made within GNU-Prolo

Résumé :

Java Path nder (JPF) is a very versatile program analysis tool, but understanding the error traces it generates is challenging. Visualizing traces can facilitate their understanding. Earlier attempts to visualize traces have resulted in specialized tools that do not interoperate with other frameworks. We present TC4JPF, which builds on Eclipse Trace Compass and enables Trace Compass to visualize JPF traces. With TC4JPF, we leverage the scalability and capabilities of Trace Compass and provide the rst solution that visualizes JPF traces in a general-purpose trace visualization tool.

During the study of fingerprint examination objects, the forensic expert selects methods and means with which he identifies and examines traces. Since most of the known forensics have an influence on the tracer substance, which in turn is multicomponent, the expert should clearly represent the mechanism of the ongoing processes in the tracer zone. In forensic work, methods and methods are widely described that allow you to work with the most common objects. Most of this information is organized in the form of practical recommendations.

We describe traces of macroorganisms in association with the body imprints of trace-producers from Ediacaran (Vendian) deposits of the southeastern White Sea region.

The traces have the form of narrow ridges or wide bands (grooves and linear depressions on natural imprints). In elongated Kimberella and Dickinsonia, the traces are stretche

This paper introduces continental trace fossils, and suggests ways in which modern and ancient traces can be used in museum exhibits. Burrows, tracks, trails, nests, borings, excrement and root patterns represent organism-substratum interactions of terrestrial and aquatic plants, invertebrates and vertebrates, and are preserved in the geologic record as continental trace fossils. Trace fossils are important because they are analogous to behaviour frozen in time and preserve information about organisms not recorded by body fossils.

ABSTRACT Bioturbating activities have played a vital role in shaping the marine ecosystem throughout metazoan history, influencing the abundance and preservation potential of body fossil-producing taxa and driving major environmental and geochemical changes. The earliest trace making behaviors arose during the late Ediacaran Period (∼ 560–541 Ma), disrupting the substrate previously occupied by dominantly sessile organisms. Simple dwelling and grazing behaviors exploited the organic-rich matgrounds, expanding into the underutilized microbial mat ecosystem. In the western United States, trace a

On the other hand, a symmetric Hopf monad is a symmetric bimonad whose fusion operators are invertible. For compact closed categories, symmetric Hopf monads are precisely the kind of monads that lift the compact closed structure to their Eilenberg-Moore categories.

According to the sedimentary substrate in which animals live, trace fossils can be divided into tracks, traceways, trails, crawling traces, resting traces, burrows on the soft ground, and erosion traces made by animals on the h

Résumé :

Track and trace in halal are globally used all over the world, and consumer still doubted about the halal status of the product in the market. The study focused on the halal critical points (HCP) in producing halal chicken meat to consumers. The objective of the study is to evaluate the existing track and trace system for halal fresh meat, to identify and adapt HCPs into the track and trace system and to measure the performance of the proposed system. There are four main stages considered in the study which are farm, slaughterhouse, producing plants and transportation. The data has been collec

Résumé :

AbstractA co-occurrence of the ichnogenus Phymatoderma and a star-shaped horizontal trace fossil was discovered from Neogene deep-marine deposits (Misaki Formation, central Japan), and is described herein for the first time. Phymatoderma consists of a straight to slightly curved tunnel that shows first- or second-order branches. The tunnels are 5.30–27.25 mm in diameter and are filled with ellipsoidal pellets. The relatively well-preserved star-shaped trace fossil is a large horizontal structure (~18 cm×19 cm) that consists of at least 10 spokes with diameters ranging from 11.49–20.96 mm. As c

Mobility trace techniques makes possible drawing the behaviors of real-life movement which shape wireless networks mobility whereabouts. In our investigation, several trace mobility models have been collected after the devices’ deployment. The main issue of this classical procedure is that it produces uncompleted records due to several unpredictable problems occurring during the deployment phase. In this paper, we propose a new procedure aimed at collecting traces while deployment phase failures are avoided, which improves the reliability of data. The introduced procedure makes possible the co

Résumé :

The author points out the key problem of the forensic doctrine of the mechanisms of trace formation – the object of cognition is limited to material traces only, which is still reflected in the unjustified situation when the clauses of traceology are identical to the clauses of forensic trace study in the “Criminalistic technique” section. The author also highlights active research in the sphere of analyzing ideal and digital traces, which is combined with the ambivalent place that they occupy in the system of criminalistics. In this connection, it is stated that criminalistics lacks a unified

Résumé :

Distributed tracing serves as a fundamental building block in the monitoring and testing of cloud service systems. To reduce computational and storage overheads, the de facto practice is to capture fewer traces via sampling. However, existing work faces a trade-off between the completeness of tracing and system overhead. On one hand, head-based sampling indiscriminately selects requests to trace when they enter the system, which may miss critical events. On the other hand, tail-based sampling first captures all requests and then selectively persists the edge-case traces, which entails the over

Résumé :

We have proposed a two-stage model-based interferometric interpolation method for filling in gaps in marine seismic data. The first stage is creating virtual traces and the second stage is utilizing modified virtual traces for interpolation. There are three steps for creating a virtual trace. First, set the virtual trace’s source and receiver coordinates and retrieve two common-receiver gathers (CRG) from existing data. At least one CRG should be obtained, otherwise, our method cannot be performed. Second, if only one CRG is obtained, then a synthetic CRG should be generated using known veloci

Résumé :

The Carboniferous Joggins Fossil Cliffs UNESCO World Heritage Site in Nova Scotia, Canada, has long been known for its extensive paleobiodiversity. The ichnofossil record at Joggins is less known than the body fossil record. Amongst the extensive ichnological collections of the late citizen-scientist Donald Reid is a morphologically unique shrimp-shaped cubichnium (resting trace). The trace fossil is associated with a faint invertebrate trackway that leads up to the resting trace and establishes its identification as an invertebrate resting trace. The trace fossil was recovered from the upper

Texte intégral

Résumé :

Compiler correctness, in its simplest form, is defined as the inclusion of the set of traces of the compiled program in the set of traces of the original program. This is equivalent to the preservation of all trace properties. Here, traces collect, for instance, the externally observable events of each execution. However, this definition requires the set of traces of the source and target languages to be the same, which is not the case when the languages are far apart or when observations are fine-grained. To overcome this issue, we study a generalized compiler correctness definition, which us

Résumé :

AbstractTurbidites and tempestites exhibit characteristic distributions of trace fossils. To gain maximum advantage of the sedimentological and palaeoecological significance of these traces, an attempt should be made to relate each trace to the associated colonization surface. This approach allows traces initiated at the normal top of an event bed to be distinguished from traces that subsequently passed into the bed from a higher colonization level or were initiated on the eroded surface of the bed.

Résumé :

We provide an axiomatisation for =<sub>pTr</sub> , a variant of probabilistic trace equivalence as formulated by Bernardo et al., 2014, in the setting of the alternating model of Hansson. The equivalence considers traces individually instead of trace distributions. We show that our axiomatisation is sound and also complete for recursion-free sequential processes. Due to the nature of the trace equivalence, the axiomatisation is particularly complex.
