INES – National Institute of Science and Technology for Software Engineering

INES at ENIA 2012

The paper titled “A Hybrid Neuron with Gradient-based Learning for Binary Classification Problems” has been accepted as full paper in the National Meeting of Artificial Inteligence (ENIA 2012).The congress will be held in Curitiba, PR, Brasil. In this work an artificial hybrid neuron with gradient-based learning was proposed to solve binary classification problems. This work is part of the project “Software Project Effort Estimation with Computational Intelligence and Statistics“.

INES at CBSoft 2012

INES at Seventh International Conference on Software Engineering Advances (ICSEA 2012) – Part II

INES researchers had two papers accepted for publication in the 7th International Conference on Software Engineering Advances (ICSEA) 2012:

1) “Evaluating performance of distributed systems with MapReduce and application traffic analysis” authored by Thiago Vieira, Paulo Fernando Soares, Marco Machado, Rodrigo Assad and Vinicius Garcia; and,

2) “A Systematic Mapping Study on Domain-Specific Languages” authored by Leandro Nascimento, Daniel Viana, Paulo Silveira Neto, Dhiego Martins, Vinicius Garcia and Silvio Meira.

Both papers are part of the research activities being performed in the project “Social Machines and Research Team – SMaRT”. We are gathering other members in this research group and creating a new one with a more general proposal, called Advanced Software Systems Engineering and Research Technologies (ASSERT): www.assertlab.com

The conference will be held in November 18-23, 2012 – Lisbon, Portugal.

A brief overview of both papers is given next:

1) Abstract. Test, monitoring and evaluation of distributed systems at runtime is a difficult effort, due the dynamicity of the environment, the large amount of data exchanged between the nodes and the difficulty of reproduce an error for debugging. Application traffic analysis is a method to evaluate distributed systems, but the capacity of analyze large amount of data is a challenge. This paper proposes and evaluates the use of MapReduce programming model to deep packet inspection the application traffic of distributed systems, evaluating the effectiveness and the processing capacity of the MapReduce programming model for deep packet inspection of a JXTA distributed storage application, in order to measure performance indicators.

2) Abstract. Domain-Specific Languages (DSLs) offer substantial gains in expressiveness and ease of use compared with general purpose languages. This way, DSLs have gained significant attention in industry and academy, as can be seen by the increased number of related publications in key conferences and journals. This paper aims to provide a broad view of the DSL research field by performing a Systematic Mapping Study. Adopting a detailed search strategy, 4450 studies were initially identified, and, after filtering, 1440 primary studies were selected and categorized using a particular classification scheme. So, this work presents the most popular application domains where DSLs have been applied, identifies different tools for handling DSLs, including language workbenches, and enumerates several techniques, methods and/or processes for dealing with DSLs.

INES is acquiring Access controls

INES at ICPADS’2012

The paper “Measuring performance of distributed applications through MapReduce and network traffic analysis” authored by Thiago Pereira de Brito Vieira, Paulo Fernando Almeida Soares, Marco Andre Santos Machado, Rodrigo Elia Assad and Vinicius Cardoso Garcia has been accepted for publication in the 18th IEEE International Conference on Parallel and Distributed Systems (ICPADS) 2012 in Singapore.

The conference will be held in december 17 – 19, 2012 at Nanyang Executive Centre, Nanyang Technological University, 60 Nanyang View, Singapore.

This activity is part of the project “Social Machines and Research Team – SMaRT” and is one of the results of the MSc research being done by Thiago Vieira.

This paper proposes the use of MapReduce programming model to deep packet inspection of distributed systems network traffic, performing a initial evaluation of effectiveness and processing capacity of MapReduce for deep packet inspection, and also evaluating the performance indicators that can be extracted to evaluate a distributed application.
