Legacy systems are large applications which are significant in performing daily organizational operations and cannot be upgraded easily especially in the absence of architectural and design documentation. Software modernization is an emerging field of software engineering, which transforms the legacy systems into new one according to the specified requirements of stakeholders. It mainly deals with improving the architecture, features, rules and data sources of existing system. It always remained a challenging task to achieve high-level representation of legacy systems. In order to achieve this high-level representation, Reverse Engineering (RE) plays an integral role. The issues of traditional RE are overcome with the help of Model Driven Reverse Engineering (MDRE) such as it generates model-based view of the legacy systems, which is comprehensible and easy to understand for practitioners. MDRE is an active research area but it provides limited tool support to extract and model both structural and behavioral aspects of legacy systems. In this paper, a novel MDRE framework named as Source to Model Framework (Src2MoF)is proposed to generate Unified Modeling Language (UML) structural (class) and behavioral (activity) diagrams from the java source code. Src2MoF is based on the principles of Model Driven Engineering (MDE), which use models as first-class citizens alleviating the complexity of software systems. The contributions of this paper are as follows;first, an Intermediate Model Discoverer (IMD) is developed using source code parser to get the intermediate representation of the system from the existing java code. Second, an open source transformation engine named UML model generator is implemented using java, which takes these intermediate models as input, and produce high-level UML models of the subject legacy system. Finally, the two benchmark case studies are presented to depict the relevance and usability of Src2MoF.

COMPUTER PHYSICS COMMUNICATIONS 2017年 218卷 43-47页

作者： Varier, K. Muraleedhara Sankar, V. Gangadathan, M. P. Univ Coll Dept Phys Thiruvananthapuram 695034 Kerala India

A java code incorporating a user friendly GUI has been developed to calculate the parameters of chemically etched track profiles of ion-irradiated solid state nuclear track detectors. Huygen's construction of wavefronts based on secondary wavelets has been used to numerically calculate the etched track profile as a function of the etching time. Provision for normal incidence and oblique incidence on the detector surface has been incorporated. Results in typical cases are presented and compared with experimental data. Different expressions for the variation of track etch rate as a function of the ion energy have been utilized. The best set of values of the parameters in the expressions can be obtained by comparing with available experimental data. Critical angle for track development can also be calculated using the present code. (C) 2017 Elsevier B.V. All rights reserved.

This paper presents a performance analysis of a PI controller implemented on the Android (TM) platform in embedded ARM. To perform the analysis are presented two execution strategies. The first strategy is the execution of PI controller from its implementation in java. The second strategy is the execution of the PI controller from its implementation in native code. In the analysis of the experiment with two suggested strategies, it was found that the controller obtained better performance and stability while running in native code.

IET SOFTWARE 2016年第6期10卷 164-172页

A fully automatic translation of unified modeling language (UML) models to complete source code is not reported so far because some implementation details will not be there in the model, or a single UML model is not enough for complete code generation, or some model elements may not be directly convertible to source code. These issues are addressed in this study. The authors take workflow modelling and automation as the focus of their research. Hence, UML activity diagram is considered. Activity diagram alone cannot give the implementation details like object interactions. A formal association is found between activity and sequence diagrams to add object interaction details to the work flow. Moreover, the authors formulate an algorithm, Am_To_Prototype, which is composed of two subroutines named Method_Body & Excecution_Logic, to generate code from the combined model of activity and sequence diagrams consisting of concurrent activities. The authors compare the proposed method with other research outcomes with respect to workflow automation, support for concurrency, etc. The proposed algorithms are able to generate class definition, method definition and control flow. A case study is presented that demonstrates the algorithm, to generate java code for the ATM operation.

ADLs are used to describe system architectures at a very high level of abstraction. The concrete ADLs are interested in generating code from an architectural description. AADL is a concrete language designed for embedded applications. It integrates a software and hardware specifications in its description. Several studies around AADL are devoted to the development of executable systems from their architectural descriptions, like Ocarina project. On the other hand, java language is widely used and supported by the majority of platforms. In this paper, we present a tool called: AADL2java, allowing java code generation from an AADL specification. For this purpose, first we take advantage of the EMF framework to specify two metamodels depicting respectively the concepts of AADL and java. Then, these two meta-models will be used to generate a java structure of an AADL specification. AADL2java tool forms an Eclipse plug-in, aiming to facilitate the automatic translation of AADL systems in java program skeletons, which may be easily completed by the developer. This will reduce the gap between software architect and developer in the system design.

Background: A molecule editor, i.e. a program facilitating graphical input and interactive editing of molecules, is an indispensable part of every cheminformatics or molecular processing system. Today, when a web browser has become the universal scientific user interface, a tool to edit molecules directly within the web browser is essential. One of the most popular tools for molecular structure input on the web is the JME applet. Since its release nearly 15 years ago, however the web environment has changed and java applets are facing increasing implementation hurdles due to their maintenance and support requirements, as well as security issues. This prompted us to update the JME editor and port it to a modern Internet programming language - javaScript. Summary: The actual molecule editing java code of the JME editor was translated into javaScript with help of the Google Web Toolkit compiler and a custom library that emulates a subset of the GUI features of the java runtime environment. In this process, the editor was enhanced by additional functionalities including a substituent menu, copy/paste, drag and drop and undo/redo capabilities and an integrated help. In addition to desktop computers, the editor supports molecule editing on touch devices, including iPhone, iPad and Android phones and tablets. In analogy to JME the new editor is named JSME. This new molecule editor is compact, easy to use and easy to incorporate into web pages. Conclusions: A free molecule editor written in javaScript was developed and is released under the terms of permissive BSD license. The editor is compatible with JME, has practically the same user interface as well as the web application programming interface. The JSME editor is available for download from the project web page http://***/jsme/

Smartphones are sensor-rich and Internet-enabled. With their on-board sensors, web services, social media, and external biosensors, smartphones can provide contextual information about the device, user, and environment, thereby enabling the creation of rich, biologically driven applications. We introduce ContextProvider, a framework that offers a unified, query-able interface to contextual data on the device. Unlike other context-based frameworks, ContextProvider offers interactive user feedback, self-adaptive sensor polling, and minimal reliance on third-party infrastructure. ContextProvider also allows for rapid development of new context and bio-aware applications. Evaluation of ContextProvider shows the incorporation of an additional monitoring sensor into the framework with fewer than 100 lines of java code. With adaptive sensor monitoring, power consumption per sensor can be reduced down to 1% overhead. Finally, through the use of context, accuracy of data interpretation can be improved by up to 80%.

Program Transformations for Asynchronous Query Submission

Program Transformations for Asynchronous Query Submission

Synchronous execution of queries or Web service requests forces the calling application to block until the query/request is satisfied. The performance of applications can be significantly improved by asynchronous submission of queries, which allows the application to perform other processing instead of blocking while the query is executed, and to concurrently issue multiple queries. Concurrent submission of multiple queries can allow the query execution engine to better utilize multiple processors and disks, and to reorder disk IO requests to minimize seeks. Concurrent submission also reduces the impact of network round-trip latency and delays at the database, when processing multiple queries. However, manually writing applications to exploit asynchronous query submission is tedious. In this paper we address the issue of automatically transforming a program written assuming synchronous query submission, to one that exploits asynchronous query submission. Our program transformation method is based on dataflow analysis and is framed as a set of transformation rules. Our rules can handle query executions within loops, unlike some of the earlier work in this area. We have built a tool that implements our transformation techniques on java code that uses JDBC calls;our tool can be extended to handle Web service calls. We have carried out a detailed experimental study on several real-life applications rewritten using our transformation techniques. The experimental study shows the effectiveness of the proposed rewrite techniques, both in terms of their applicability and performance gains achieved.
