Wireless Sensor Networks (WSNs) typically include thousands of resource-constrained sensors to monitor their surroundings, collect data, and transfer it remote servers for further processing. Although WSNs are considered highly flexible ad-hoc networks, network management has been a fundamental challenge in these types networks given the deployment size associated quality concerns such as resource management, scalability, reliability. Topology is viable technique address concerns. Clustering...

We show how a common language of variability can be used to enhance the expressiveness Domain Specific Language (DSL). DSLs have been proposed as mechanism for expressing variability. Variability between models in given domain or family systems is captured by constructs, implying that all possible this are allowed variations. explore possibility independently base modeling language. works small well general purpose languages like UML. Implications approach standardized, and do not include mechanisms.

A scalable approach for software product line testing is required due to the size and complexity of industrial lines. In this paper, we present a specialized algorithm (called ICPL) generating covering arrays from feature models. ICPL makes it possible apply combinatorial interaction lines found in industry. For example, allows pair-wise be readily applied projects about 7,000 features 200,000 constraints, Linux Kernel, one largest where model available. compared three leading algorithms...

Many Internet of Things (IoT) networks are created as an overlay over traditional ad-hoc such Zigbee. Moreover, IoT can resemble that support device-to-device (D2D) communication, e.g., D2D-enabled cellular and WiFi-Direct. In these <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ad-hoc</i> types networks, efficient xmlns:xlink="http://www.w3.org/1999/xlink">topology management</i> is a crucial requirement, in particular massive scale...

The tutorial will present the outcome of work done by Joint Submission Team against Request For Proposals for a Common Variability Language issued OMG (Object Management Group). language and experiments some consortium members on tools supporting preliminary CVL.

Current model-driven software product line development is mostly based on feature/variability modeling techniques, however, we see the potential for automatic assistance in identifying commonality and variability of a set models within domain synthesizing model those. This paper presents generic approach using comparison. For difference detection, applies EMF Compare, comparison tool. specifying variability, Common Variability Language (CVL), language expressing variability. The SPL...

The Common Variability Language (CVL) is a domain-independent language for specifying and resolving variability. It facilitates the specification resolution of variability over any instance defined using MOF-based meta-model.

The application of search-based software engineering techniques to new problems is increasing. Feature location one the most important and common activities performed by developers during maintenance evolution. Features must be located across families products artifacts that realize each feature identified. However, when dealing with industrial artifacts, search space can huge. We propose compare five algorithms locate features over product models guided latent semantic analysis (LSA), a...

In this work we propose a feature location approach that targets models as the realization artifacts. The combines Genetic Algorithms and Information Retrieval techniques. Given model description, fragments extracted from are evolved using genetic operations. Then, Formal Concept Analysis is used to cluster based on their common attributes into candidates. Finally, Latent Semantic rank candidates similarity with description. As result, algorithm evolves population of find set most suitable...

Immunofluorescence labelling of myrosinase in paraffin sections was used to study the fate, appearance, and distribution myrosin cells Brassica napus after seeding. Labelling achieved using monoclonal antibodies (MAbs) produced against myrosinase. Myrosinase extracted purified from seeds rape (Brassica napus) homogeneity. Mice were immunized with highly fusion cloning hybridoma cells, specificity tested characterized. One antibody inhibited activity. Precipitation activity coupled monosized...

Abstract The success of the ongoing fourth industrial revolution largely depends on our ways to cope with novel design challenges arising from a combination an enormous increase in process and product complexity, as well expected autonomy self-organization complex diverse hardware–software installments, often called systems-of-systems. In this paper, we employ service-oriented architectural paradigm, materialized Eclipse Arrowhead framework, represent modern systems engineering principles...

AIMS: To compare oestrogen receptor measurements on fresh tissue done by an enzyme immunoassay (ER-EIA, Abbott) and immunohistochemical technique (ER-ICA, using formalin fixed, paraffin was embedded material. METHODS: The ER-EIA is based a sandwich frozen tissue, the absorbance values were read Quantum Analyzer. Sections cut from corresponding wax blocks, after pretreatment with pronase DNase, slides incubated monoclonal antibody. immunoperoxidase staining scored semiquantitatively,...
