Programmers frequently make use of APIs. However, these usages can result in unintended, negative behavior, when developers are not aware of the correct usage or side effects of that API. Detecting those API misuses by means of automatic testing is challenging, as many test suites do not cover this unintended behavior. Instead, API usage patterns are used as specifications to verify the correctness of applications. However, to find meaningful patterns, i.e., those capable of fixing the misuse, the context of the misuse must be considered. Since the developer usually does not know which API is misused, a much larger code section has to be verified against many potential patterns. In this paper, we present a new idea to enhance API misuse detection by means of commits. We discuss the potential of using commits (1) to decrease the size of the code to be considered, (2) to identify suspicious commits, and (3) to contain API usages which can be used to shepherd API specification mining. This paper shows first results on the usability of commits for API misuse detection and some insights into what makes a commit suspicious in terms of exhibiting potential API misuses.

Android malwares are proliferating in the public spaces like never before. The urge of the adversaries to collect user data through various means to establish a pattern or behaviour is ever growing. The malwares have become sophisticated to label them as good or bad. In this paper, we try to establish a good set of features from Android applications to label them as benign or malware. We have developed a framework to automatically extract features via stationary, static and dynamic analysis of the Android applications. Pre-static analysis include application meta-data from playstore and Android manifest from application. Static analysis of the application comprises flow-droid's source-sink identification, api to permission mapping and n-gram statistical analysis. Dynamic analysis of the application is performed using Google's droidbox and monitoring the system calls. The features are exported in a general format and can act a input to a learning based model for application classification.

Background: application programming interfaces (APIs) are key to software reuse. Software developers can link functionality and behavior found in other software with their own software by taking an API into use. However, figuring out how an API works is usually demanding, and may require that the developers spend a notable amount of time familiarizing themselves with the API. Good API documentation is of key importance for simplifying this task. Objective: To present a comprehensive, unbiased overview of the state-of-the-art on tools and approaches for API documentation generation. Method: A systematic mapping study on published tools and approaches that can be used for generating API documentation, or for assisting in the API documentation process. Results: 36 studies on API documentation generation tools and approaches analyzed and categorized in a variety of ways. Among other things, the paper presents an overview of what kind of tools have been developed, what kind of documentation they generate, and what sources the documentation approaches require. Conclusion: Out of the identified approaches, many contribute to API documentation in the areas of natural language documentation and code examples. Many of the approaches contribute to the accuracy and correctness of API documentation , but also to ease developers understanding of the documentation. Most of the approaches are automatic, simplifying the API documentation generation notably, under the assumption that relevant sources for the generation are available. Most of the API documentation approaches are evaluated either by execution of the approach followed by analysis of the results, or by empirical evaluation methods.

In order to improve the precision of the sprayer field operation and reduce the overlapping rate as well as the missing rate during the spray process, an auxiliary navigation system based on Baidu map JavaScript API (application programming interface) was designed to prevent overlapping spray and missing spray. Technologies such as serial communication, GPS (Global Positioning System) positioning, Baidu map API, path planning and geographic information system were integrated in this system. Accordingly, the functions of vehicle positioning, path planning, job navigation, doodle in operated areas, real-time data collection and automatic processing in spray process could be achieved. In order to verify the reliability and stability of the designed navigation system, an experimental platform was developed for auxiliary navigation system based on the self-developed 3WPG-3000 high clearance self-propelled sprayer. In addition, an RTK GPS and a computer were also integrated in this system. Moreover, experiments of AB line navigation and free line navigation were carried out. The results indicated that the overlapping rate of the AB line navigation and the free line navigation as well as the missing rate of them were 2.54%, 0.26% and 4.43%, 0.88% respectively, which meet the needs of sprayer field operation.

Multi-access Edge Computing (MEC) converges telecommunications and cloud technology at the Radio Access Network (RAN). Taking the advantages of telecom cloud MEC allows rapid content processing at the very edge of the mobile network, delivering real-time services. The research is aimed to further develop the MEC potential for improving RAN performance parameters. The idea is to monitor UE connectivity parameters and to trigger a change of used radio technology as earlier as possible. With moving the connectivity management logic in MEC, data flows do not reach the core network. The paper proposes an extension of Radio Network Information application programming Interface (API) for connectivity management. The proposed APIs are described by information flows, data and behavioral models.

The description of an innovative framework built on top of Web based visual programming environment is the primary aim of this contribution. In the last decade, many frameworks oriented to visual languages have been introduced in literature to improve the skill on programming languages, but at the best of our knowledge, no framework has been specially designed to support collaborative work on heterogeneous distributed environments. Therefore, SIRENE introduces a new framework in which beginners and experts can cooperate to develop algorithms by using a visual and iconic paradigm. Students, in the classroom or connected from everywhere, can he involved into the definition of the algorithm, can asynchronously modify the common working space, show a visual function to expert, thus the server hosts a shared space in which the algorithms can be visualised and modified by all of the SIRENE clients. SIRENE is primarily a visual framework oriented to collaborative approaches in which each user can visualise the evolution or implementation of some algorithms and modify it during its development by other users.

We describe the design and implementation of the new, little-endian Linux on Power operating environment, with a particular emphasis on its application interfaces. The new environment was designed to simplify porting of applications from other processor architectures to Power. It uses little-endian data formats to reduce the need for code adaptation and debugging during porting, and to simplify the use of commodity off-the-shelf system components, such as I/O adapters and accelerators. We took advantage of introducing a new operating environment to optimize the platform application binary interface (ABI) for new programming patterns and paradigms, resulting in enhanced out-of-the-box performance. The new ABI responds to increasing componentization of applications by reducing the overhead involved in function calls with an emphasis on accelerating calls to short functions as well as calls to runtime-resolved functions, i.e., functions in shared libraries, function pointers, virtual methods, and interface functions.

Cognitive applications are complex and are composed of multiple components exhibiting diverse workload behavior. Efficient execution of these applications requires systems that can effectively of handle this diversity. In this paper, we show that IBM POWER9 (TM) shared memory systems have the compute capacity and memory throughput to efficiently handle the broad spectrum of computing requirements for cognitive workloads. We first review the GraphBLAS interface defined for supporting cognitive applications, particularly whole-graph analytics. We show that this application-programming interface effectively separates the concerns between the analytics application developer and the system developer and simultaneously enables good performance by permitting system developers to make platform-specific optimizations. A linear algebra formulation and execution of betweenness centrality kernel in the High-Performance Computing Scalable Graph Analysis Benchmark, for 256 million vertices and 2 billion edges graphs, delivers a sixfold reduction in execution time over a reference implementation. Following that, we present the results of benchmarking the forward propagation step of deep neural networks (DNNs) written in GraphBLAS and executed on POWER9. We present the rationale and evidence for weight matrices of large DNNs being sparse and show that for sparse weight matrices, GraphBLAS/POWER (R) has a two orders-of-magnitude performance advantage over dense implementations. applications requiring analysis of graphs larger than several tens of billion vertices require distributed computing environments such as Apache Spark to provide resilience and parallelism. We show that when linear algebra techniques are implemented in an Apache Spark environment, we are able to leverage the parallelism available in POWER9 Servers.

MULTIMEDIA TOOLS AND applicationS 2017年第12期76卷 14247-14304页

In the last few years, multimedia technologies in general, and Real-Time multimedia Communications (RTC) in particular, are becoming mainstream among WWW and smartphone developers, who have an increasing interest in richer media capabilities for creating their applications. The engineering literature proposing novel algorithms, protocols and architectures for managing and processing multimedia information is currently overwhelming. However, most of these results do not arrive to applications due to the lack of simple and usable APIs. Interestingly, in this context in which APIs are the critical ingredient for reaching wide developer audiences, the scientific literature about multimedia APIs and their usability is scarce. In this paper we try to contribute to fill this gap by proposing the RTC Media API: a novel type of API designed with the aim of making simple for developers the use of latest trends in RTC multimedia including WebRTC, Video Content Analysis or Augmented Reality. We provide a specification of such API and discuss how it satisfies a set of design requirements including programming-language agnosticism, adaptation to cloud environments, support to multisensory multimedia, etc. After that, we describe an implementation of such an API that has been created in the context of the Kurento open source software project, and present a study evaluating the API usability performed in a group of more than 40 professional developers distributed worldwide. In the light of the obtained results, we conclude that the usability of the API is adequate across the main development activities (i.e. API learning, code creation and code maintenance), with an average usability score of 3.39 over 5 in a Likert scale, and that this result is robust with respect to developers' profiles, cultures, professional experiences and preferred programming languages.
