In this paper, the recognition information in aircraft images of Head-Up Display (HUD) was made using artificial neural network (ANN) and a correlation algorithm. During the flight tests, the images displayed on the HUD could be stored for later analysis. HUD images presents many aircraft data provided by its avionics system (e.g. Altitude, feet, time). Therefore, HUD images are a primary source of information for most aircraft and pilots, especially in military missions. At IPEV (Flight Test" a Research Institute), the extraction of information from HUD images is performed manually, frame by frame, for later analysis. The big issue is that in one hour of flight test about 36,000 frames are generated. Therefore, data extraction becomes complex, time consuming and prone to failures. To reduce these problems, the IPEV developed an algorithm that load HUD images and then partitions the images in regions that were classified, recognized and converted into text by using ANN and a correlation algorithm. The development of the algorithm is presented in this paper.

The scalability of systems is essential in scenarios where there is a lot of concurrent users. Some systems have peak access during certain times, others have a lot of concurrent users regularly. Thus, these systems must be able to perform equally as a growing number of requests. The study of system scalability that manipulate database considers read operations in database systems. However, in this paper we present an approach for horizontal scalability on systems that perform write database operations. The proposed approach uses queuing theory and differs from commonly developed solutions like clustering databases and elasticity in the cloud. A case study was conducted with an application of persistent logs, and two versions of the application have been implemented in order to compare the efficiency of the use of queues. Results show the efficiency of the use of queuing theory implemented to allow scalability for applications with a large amount of writing database operations.

This paper presents an exploratory study on agile techniques for software testing Test-Driven Development and Behaviour-Driven Development for integration with the agile software development technique known as Domain-Driven Design. It also comprises a comparison between both test approaches, enhancing the strengths and weaknesses of each one. To make it feasible the integration proposal, an example of domain using Apache Isis framework was developed. According to the study performed, the possibility of creating an automatic test generator to make it agile the validation of entities attributes of the domain model was noted.

This paper tackles the use of the Scrum agile method within a Brazilian small business enterprise. It provides monitoring activities for software project management. It involves the use of human, financial, and temporal resources during a project development, increasing the rate of its successful deliveries. In order to enable the Scrum adoption, the following four distinct steps were defined: infrastructure set up, team training, Scrum agile deployment, and deployment refinement. An analysis of its main results was obtained from the application of a survey to all project stakeholders. The major improvements were identified since the first sprints, mainly involving communication, team motivation, and adaptation agility, during the chosen case study within a small enterprise.

A structured environment of IT risk management can influence an improving the flexibility and adaptability of business processes and information technology, including information systems in a secure manner. As with all other technologies, the adoption of SOA involves risk. These risks often manifest themselves during an implementation of the SOA solution and arise mainly due to insufficient detail in the SOA project. In this paper, we present the main ideas about the impact of IT risks on the life cycle of the implementation of service-oriented architecture and how we could minimize these impacts by using a model of managing IT risks.

Communication devices like cell phones, refrigerators, TVs, and others have been considered lately as some Internet of Things (IoT) components, mainly due to the embedded systems evolution and web connectivity. During the first semester of 2014, at the Brazilian Aeronautics Institute of Technology (Instituto Tecnologico de Aeronautica -- ITA), a successful Interdisciplinary Problem Based Learning (IPBL) experience took place. At that time, almost 60 graduate students from three different courses (CE-229 Software Testing, CE-240 Database System Project, and CE-245 Information Technologies), within just 17 academic weeks, had the opportunity to conceptualize, model, and develop a system prototype to capture, store, and analyze credit card transactions. This system, named BDIT-C2 (Big Data, Internet of Things, and Credit Cards), has used an Application Programing Interface to enable communication devices to make purchases, allowing e-commerce through a web portal where fraud analysts could monitor all suspicious transactions.

In this article, it is presented a mathematical model for the additional financial value generated in software projects, as a function of the number of incremental deliveries during the project. Based on this model, it was presented the theoretical asymptotic limit, for infinite deliveries during the project. This practice is called Continuous Deployment (CD), already used by many companies such as Google and Facebook. As financial evaluation measuring, it was used the Net Present Value (NPV). It was also measured how the use of incremental deliveries can create additional NPV for software projects which have short duration (maximum of six months), median duration (one year) and long duration (two years). At the end, it is argued that this additional value can be strategic for maintaining a sustainable portfolio of innovation projects.

Web services represent a way to share data and shall be treated as a solution for interoperability between heterogeneous systems. However, by having a public infrastructure, subject to attacks, security issues have become indispensable and challenging. To ensure the security of these applications, some safety specifications are generally used, such as the XML signature, XML encryption and WS-Security specifications. However, the application of these specifications may degrade the performance of these systems, especially the specification responsible for encryption, the XML encryption. This study besides investigating the causes of this problem, propose a solution designed to reduce the impact of this degradation, through the combined use of different cryptographic algorithms to encrypt SOAP messages.

The process of software testing in agile environments presents complexity due to the need to be performed at short time intervals. Currently, there is no consensus in literature of the best approach to deploy agile testing. The testing management is often one of the hardest steps to be adapted to these methods, due to the short time for deliveries, which reduces the time available for testing, as a result, it is usually relegated to the background. In order to assess the viability and possible benefits in the implementation of an agile testing process, an exploratory research was made on the deployment approaches of agile testing, successfully used in different contexts and some of these approaches have been implemented in a software development company, which uses principles of agile methods.
