A novel methodology for accelerating bitstream relocation in partially reconfigurable systems

2012

International audience; Xilinx Virtex FPGAs offer the possibility of Partial Reconfiguration (PR). Arbitrary tasks can be allocated and de-allocated onto FPGA without system interruption. However, mapping a task to any available PR region requires a unique partial bitstream for each partition, hence reducing memory storage requirements. In recent years, an interest on overcoming this problem has lead to the concept of Partial Bitstream Relocation (PBR). The principle is to perform bitstream modification to map it to different regions. However, PBR consumes scarce resources in hardware implementations, and introduces a prohibitive time overhead when done in software. In order to find the bes…

Wearable photoplethysmography device prototype for wireless cardiovascular monitoring

2014

The aim of the study was to develop a prototype system of the smart garment for real time telemetric monitoring of human cardiovascular activity. Two types of photoplethysmography (PPG) sensors for low noise and artefact free signal recording from various sites of the human body that were suitable for integration into smart textile were investigated. The reflectance sensors with single and multiple photodiodes based on "pulse-duration-based signal conversion" signal acquisition principle were designed and evaluated. The technical parameters of the system were measured both on bench and in vivo. Overall, both types of PPG sensors showed acceptable signal quality SNR 86.56±3.00 dB, dynamic ra…

Embedded Model Control and dynamic simulation

2006

Embedded model control (EMC) is and end-to-end control technology addressed to industrial engineers and centered on the embedded model, a stylized discrete-time state equation of the whole plant, including environment, communication and computing resources. The embedded model, which is the core of the control unit, is derived and validated from a fine model of the plant which is implemented as a simulator code. The latter acts as a faithful and friendly test-bench where assessing control units before they are loaded into target processor. The paper illustrates the requirements and architecture of the EMC simulator under continuous improvement. A case study closes the paper.

Vector representation of non-standard spellings using dynamic time warping and a denoising autoencoder

2017

The presence of non-standard spellings in Twitter causes challenges for many natural language processing tasks. Traditional approaches mainly regard the problem as a translation, spell checking, or speech recognition problem. This paper proposes a method that represents the stochastic relationship between words and their non-standard versions in real vectors. The method uses dynamic time warping to preprocess the non-standard spellings and autoencoder to derive the vector representation. The derived vectors encode word patterns and the Euclidean distance between the vectors represents a distance in the word space that challenges the prevailing edit distance. After training the autoencoder o…

Influence of the Madden-Julian Oscillation on Southern African summer rainfall

2007

Rain-causing mechanisms over Southern Africa (south of 15˚S) involve both tropical and temperate dynamics. Most studies focused on the synoptical timescale, while the intraseasonal (20-120 days) variability has more been neglected to date. This study aims at determining whether the dominant mode of intraseasonal variability in the Tropics, namely the Madden-Julian Oscillation (MJO), has a significant impact on Southern African rainfall and associated atmospheric dynamics. The examination of outgoing longwave radiation (OLR) over Southern Africa shows indeed significant intraseasonal fluctuations at the 30-60 day timescale, i.e. in the pe- riods that are typically reminiscent of the MJO. In ord…

Economic Value Added – A General Review of the Concept

2017

Business organizations of the 21st century, a century driven by globalization,internationalization and speed, must compete on changing and evolving markets. One of the maingoals of every business is to create value for its shareholders, value that is generated by the properusage of existing resources. The notion that can be utilized to successfully illustrate the increase ineconomic value is the economic value added concept.. The Economic Value Added concept knownalso as EVA is an add on to value, value based management and economic value.. EVA is a methodand a tool for quantification and measurement of the value created by a business organization.

Dynamic scheduling of periodic skippable tasks in an overloaded real-time system

2008

International audience; The need for supporting dynamic real-time environments where changes in workloads may occur requires a scheduling framework that explicitly addresses overload conditions, allows the system to achieve graceful degradation and supports a mechanism capable of determining the load to be shed from the system to handle the overload. In applications ranging from video reception to air-craft control, tasks enter periodically and have response time constraints, but missing a deadline is acceptable, provided most deadlines are met. Such tasks are said to be occasionally skippable and have an assigned skip parameter. We look at the problem of uniprocessor scheduling of skippabl…
