A Practical Approach to Rapid Prototyping of SCA Waveforms
… and the Software Communication Architecture (SCA) comes the need for a rapid prototyping approach to radio design. In the past, radios have traditionally been designed to have a static implementation with the express goal of implementing a specific type of communication, such as 802.11b, CDMA …

Reconfigurable SCA System Development Using Encapsulated Waveform Applications and Components
The Software Communications Architecture (SCA) is a standard for software defined radios (SDR) designed in part to promote code reuse for long-term development. With the emergence of adaptive/cognitive radios, new SDRs that are capable of reconfiguration during runtime must be developed. One …

Logical Representation of FPGAs and FPGA Circuits within the SCA
… The Software Communications Architecture (SCA) is a specification for a software radio architecture produced by the Joint Program Executive Office (JPEO) Joint Tactical Radio System (JTRS). The 2.2 revision of the SCA only implies support for GPPs, with no specified support for additional …

At-risk individual's perspectives of Spinocerebellar Ataxia (SCA) Presymptomatic Testing (PT)
Since the introduction of presymptomatic testing for Spinocerebellar Ataxia in South Africa, no research has looked at the impact, perceptions or acceptance of such testing within this diverse population. Despite the relatively high frequencies of late onset autosomal dominant conditions in South …

Design and Implementation of an Efficient SCA Framework for Software-Defined Radios
… The Software Communications Architecture (SCA), developed by the Joint Tactical Radio System program of the US Department of Defense, is an open architecture for implementing SDR, relying on commercial technology, standard interfaces, and well-known design patterns. Although the SCA is …

Implementation of SCA-Resistant CPU and an ECDLP Engine on FPGA Platform
… countermeasure to prevent side-channel analysis (SCA) attacks on an embedded system. We present an SCA-resistant processor design in the context of an embedded design flow for FPGA. It integrates an SCA-resistant custom instruction set on a soft-core CPU and derives an SCA resistance from …

SCA-Resistant and High-Performance Embedded Cryptography Using Instruction Set Extensions and Multi-Core Processors
… cryptography enable Side-Channel Attacks (SCAs), which can break cryptographic implementations in a very short time with a quite low cost. In this dissertation, we propose solutions to efficient implementation of SCA-resistant and high-performance cryptographic software on embedded systems. …

Introgression of the Genes for Sesquiterpene Carboxylic Acid Synthesis From a Wild Tomato, Lycopersicon Hirsutum, Into the Cultivated Tomato for Increased Host -Plant Resistance to Insect Pests
… were separated into high and low classes for SCA levels and the DNA combined of individual plants within the phenotypic classes. Bulk segregant analysis was used to identify polymorphic AFLP markers present in LA 1777 and absent in 'Chico III' and LA 1033. Comparisons of these polymorphic AFLP …

Social Conflict Avoidance: Is It a Unique Construct
… the uniqueness of Social Conflict Avoidance (SCA), it was compared with nonassertiveness, shyness, low masculinity, and Self-defeating Personality Disorder. These four variables correlated highly with SCA in Brock (1994). Participants were 222 undergraduate students (110 male, 112 female) at a …

MONITORING OF NORTH AMERICAN SNOW COVER AND ENSO EFFECTS
… was conducted to monitor the Snow Cover Area (SCA) and to evaluate the effects of El Nino and La Nina on SCA in North America (Excluding Greenland) since 2000/2001 to 2010. The NASA ((National Aeronautics and Space Administration) Earth Observing System Moderate Resolution Imaging …

Factors Related to Self-Care Agency and Self-Care Practices of Obese Adolescents
… and life events (LE)--and the self-care agency (SCA) and self-care practices (SCP) among obese adolescents. The relative predictive strength of each BCF in relation to the outcome variables was also explored. Orem's self-care theory provided the conceptual framework for this study. The …

Estimation de la superficie du couvert nival à partir d'une combinaison des données de télédétection MODIS et AMSR-E dans un contexte de prévision des crues printanières au Québec
… remote sensing can improve snow cover area (SCA) estimation due to high spatial resolution but is limited by cloud cover and incoming solar radiation. Passive microwave remote sensing is complementary by its near-transparence to cloud cover and independence to incoming solar radiation, but is …

Creation of crosslinkable interphases in polymer blends by means of novel coupling agents
… For this purpose novel coupling agents (named SCA) containing 2-oxazoline, 2-oxazinone, and hydrosilane reactive sites have been prepared. In blends of amino- functional and carboxylic acid terminated polymers the oxazoline and oxazinone units of the SCA react selectively with one of the …

Sickle cell anaemia in Cameroon : co-inheritance of α-thalassemia, HBB gene haplotypes, clinical & haematological characterisations
Background: Although sickle cell anaemia (SCA) is genetically characterised by a single point mutation, patients can manifest varying degrees of clinical severity due to various genetic modulators that affect the phenotype of this disease. The co-inheritance of alpha-thalassemia (α-thalassemia) has …

Advances in the Side-Channel Analysis of Symmetric Cryptography
Side-Channel Analysis (SCA) is an implementation attack where an adversary exploits unintentional outputs of a cryptographic module to reveal secret information. Unintentional outputs, also called side-channel outputs, include power consumption, electromagnetic radiation, execution time, photonic …
