INTRODUCTION Contact tracing is a critical strategy required for timely prevention and control of Ebola virus disease (EVD) outbreaks. Available evidence suggests that poor contact tracing was a driver of the EVD outbreak in West Africa, including Sierra Leone. In this article, we answered the question as to whether EVD contact tracing, as practiced in Western Area (WA) districts of Sierra Leon...

We give cryptographic schemes that help trace the source of leaks when sensitive or proprietary data is made available to a large set of parties. A very relevant application is in the context of pay television, where only paying customers should be able to view certain programs. In this application, the programs are normally encrypted, and then the sensitive data is the decryption keys that are...

Requirements are at the core of all project deliverables. Ensuring that all project requirements are achieved by the project can be difficult to validate if no further means of tracing requirements is employed. Requirements traceability hence is a critical component of any project, as it provides the ability for a project to articulate how any given requirement has been met by the project deliv...

We present the overall design of an object oriented library for use when developing tracing capable applications The library is im plemented as java classes and consists of de nitions of the basic classes for registration of objects and relations as well as methods for di erent types of tracing procedures and components for manipulating tracing results and viewing them graphically

The goal of this master thesis is to study, compare, and improve existing approaches for direct ray tracing trimmed NURBS surfaces. In order to be able to study the topic efficiently, a library for NURBS evaluation has been implemented. The library is supposed to be easily integrated in any ray tracing application to make it support direct ray tracing trimmed NURBS surfaces.

We propose a GA ray-tracing method which applies a genetic algorithm to ray tracing in order to complete the large-scale computation of estimating radio propagation in a practical amount of time. We describe the GA ray-tracing method as well as a demonstration of its effectiveness through numerical simulation .

we reported here tasks we accomplished to improve the 2D curve tracing algorithm: 1) Optimized individual steps in the tracing program with tools from the field of digital image processing; 2) Implemented training sets and evaluation conditions that teach the program to look for parameters that fit a wide variety of data quality.
