A total of 269 Holstein cows were selected to test estrus using the independent "Jing M" detection system. For estrus cows detected by the system an experienced veterinarian checked them again by using rectum checks; after this the positive and accuracy rates of the system were evaluated. Finally the consistency of the detection system with rectum checking was analyzed using the Kappa value...
In present power system structure, large capacity thermal power plants have been installed at remote locations from load centers. The power from generation to load centers is transmitted through long EHV transmission lines & number of EHV substations of various voltage levels are required for step down the power. This extended EHV corridor have acquired large chunk of land & raised the issues...
This paper presents an observational study conducted at the public environment investigating children's engagement with a social robot within a pretend play scenario. A pretend play system was designed in order to address the challenges of evaluating child-robot interaction by exploiting the advantages of ubiquitous robotics and ambient intelligence of multimodal, multi-sensory perception. The system...
The Paper presents in-depth analysis of Feeder Reconfiguration (FR) of 139 bus, 33 kV distribution system (Jaipur city, Rajasthan, India), by means of Minimum Power Flow based Reduction (MPFR) technique. The earliest model of Jaipur city as Test system is designed and simulated in Mi-Power software. FR of the considered system has been performed for three network configurations namely Existing System...
Multigap Resistive Plate Chambers (MRPCs) are gas detectors operating in avalanche saturated mode at a standard voltage ranges around 18 ÷ 20 kV, applied by means of DC Low Voltage to DC High Voltage converters (DC/DC converters). This device is used in the Extreme Energy Events Project (EEE Project), an innovative experiment to study high energy cosmic rays by using a network of tracking detectors,...
The synthesis and mapping of applications to configurable embedded systems is a notoriously hard process. Tools have a wide range of parameters, which interact in very unpredictable ways, thus creating a large and complex design space. When exploring this space, designers must understand the interfaces to the various tools and apply, often manually, a sequence of tool-specific transformations making...
This paper presents a software platform for the integration of discrete event systems tools that is being developed within the FP7 European project DISC “Distributed supervisory control of complex plants”. The objective of this software platform is to integrate several tools dealing with Petri nets and automata. The purpose is twofold: first allow for a rigorous comparison of the methods and algorithms...
A new methodology has been developed for automated fatigue crack growth (FCG) life analysis of components based on finite element (FE) stress models, weight function stress intensity factor (SIF) solutions, and algorithms to define idealized fracture geometry models. The idealized fracture geometry models are rectangular cross-sections with dimensions and orientation appropriate to an irregularly...
In this research we present a simulation-based approach to study alternative dynamic assignment policies in an information technology (IT) service delivery environment. Our overarching goal is to find the most cost-effective assignment of service requests to cross-trained agents in a large-scale network. We present a novel heuristic algorithm that assigns an analytically described allocation index...
Planning a complex software modification task imposes a high cognitive burden on developers, who must juggle navigating the software, understanding what they see with respect to their task, and deciding how their task should be performed given what they have discovered. Pragmatic reuse tasks, where source code is reused in a white-box fashion, is an example of a complex and error-prone modification...
Research has provided evidence that type usage in source files is correlated with the risk of failure of software components. Previous studies that investigated the correlation between type usage and component failure assigned equal blame to all the types imported by a component with a failure history, regardless of whether a type is used in the component, or associated to its failures. A failure-prone...
This paper will cover the background, current spiral developments, roll out, and sustainment of the US Army's newest At-Platform Automatic Test Systems (APATS) equipment for TWVs (Tactical Wheeled Vehicles). The equipment, called the SWICE (Smart Wireless Internal Combustion Engine) system, was developed for vehicle diagnostics systems in at-platform and embedded applications, including prognostics...
This paper describes a model-based method for the automatic generation of test cases in software product lines. The approach is completely based on well-known standards, such as UML 2.0, the UML Testing Profile and the QVT Language. To reach the goal, it is essential to maintain the traceability between different abstraction levels, as well as between domain and product engineering levels. The method...
Many of todaypsilas service analysis and design techniques rely on ad-hoc and experience-based identification of value-creating business services and implicitly assume a ldquogreen-fieldrdquo situation focusing on the development of completely new services while offering very limited support for discovering candidate services from pre-existing software assets. In this article, we introduce a novel...
This paper proposes an extension to the UML testing profile to manage variability in testing artifacts for software product lines. The proposed extension has two main points: (i) Defining an extended architecture for the UML testing profile to deal with variability in the test models, and (ii) Defining the behavior to include variation points in the SPL. To this aim, this work focuses on the test...
Large software projects often rely on third-party libraries, made accessible through application programming interfaces (APIs). We have observed many cases where APIs are used in ways that are not efficient. We developed a technique to automatically detect inefficient API usage in software projects. The main hypothesis underlying the technique is that client code that imitates the behavior of a library...
When developers join a project, they find themselves in a new project landscape and must orient themselves quickly. To investigate the nature of this project landscape, and how we could help newcomers orient themselves, we have started an exploratory study using grounded theory. We primarily collect our data by interviewing experienced developers who recently joined ongoing projects. We are already...
As a framework evolves, changes in its application programming interface (API) can break client programs that extend the framework. Repairing a client program can be a challenging task because developers need to understand the context surrounding the API change. This paper describes SemDiff, a tool that recommends replacements for framework methods that were accessed by a client program and deleted...
Most CSCW and groupware systems focus the activities of distributed teams involved in large projects by means of tools for communication and awareness. The activities of small collocated teams are often neglected. Analyzing preliminary requirements of small teams, it is possible to observe the need of tools to help the elaboration of project documentation. This paper presents a multi-agent system...
Workflow technologies automate, totally or partially, the business processes. Such technologies use standard languages, like BPMN, to model business processes, BPMN. On the other hand, from the software engineering, OMG has defined a metamodel for the software process engineering (SPEM). This metamodel is used for describing a concrete software development process. The objective of this research work...
