Automotive electronic control units (ECUs) have been the focus of many security researchers who have demonstrated the ability to affect the deterministic operation of safety critical vehicle cyber physical systems. Flaws in software design that have direct impacts to the functional safety of a target vehicle have been discovered. The rapid increase in data connectivity within a modern automobile has...
Due to the growing size of compute clusters, large scale parallel applications increasingly have to deal with hardware malfunctions and other failure scenarios during execution. The overall goal of this research is to get good performance of MapReduce applications despite failures. The paper focuses on evaluation of the performance of two representative Hadoop MapReduce applications, 'WordCount' and...
The P4 language provides a way to describe a custom network packet processing behavior that involves header parsing, matching and assembling modified packets. Such abstraction represents a significant step towards removing the limitation of fixed-function networking devices. Our live demonstration shows a straightforward usage of an algorithm and tool that maps a P4 program to a general architecture...
This paper presents differential pressure based flow configuration software implemented using FDT2 technology. FDT2 is a latest version of FDT standard (IEC62453) which is useful for configuration, monitoring, diagnosis and asset management of field device. Using FDT2 technology, client server system for flow configuration will be achieved keeping the interoperability of host system. The original...
Household energy consumption is largely inefficient. In recent years, development in residential energy-use optimisation has attracted a great deal of attention. Given that consumers comprise a significant part of total demand, there is an incentive to assist users to manage household demand. This paper provides an introduction to Home Energy Management (HEM). An overview of available Home Energy...
A problem-oriented processor on the basis FPGA for high-precision calculations in floating-point formats (64-, 80-, 128-bit) for solving poorly conditioned systems of linear algebraic equations by the Gauss method was developed.
A typical medical ultrasound-imaging system consists of a passive probe and a backend system containing the analog frontend and the digital processing unit, to which the probe connects over a coaxial cable harness. Digital processing is increasingly performed in software on powerful GPUs or multicore CPUs. These new system architectures have not only enabled new imaging modalities (Ultrafast Imaging,...
It is important to allow the test engineer great flexibility when developing a test program. Highly skilled test engineers desire flexibility and different hardware platforms to test a Unit Under Test (UUT). In the past, the engineer was told to use specific test equipment and not provided with the option to program an instrument to their specific test and diagnostic plans. Being stuck in a rut on...
This paper describes an innovative software interface design in support of signal-oriented test programming. The design makes use of modern Domain Specific Language (DSL) concepts and advanced C# language features to create an interface with excellent usability features and low implementation overhead. The interface is proposed as a more usable alternative to the Test Procedure Language (TPL) specified...
Much like the proliferation of different Automatic Test Equipment (ATE) within the DoD Services, there has been a similar proliferation of various programming languages for developing Test Program Sets (TPS) to be used on those same ATE. The use of multiple languages leads to a variety of unfavorable situations, including, among others: • Complexity of re-hosting software to new ATE • Difficulty transitioning...
To utilize the proper test techniques that expand our test and diagnosis process we should regularly evaluate and integrate new devices and new techniques. Willingness to embrace change is the major requirement for successful technology integration. Test technology is continuously and rapidly evolving. It is an ongoing process and demands continual research and understanding. Effective integration...
DOD Automatic Test Systems (ATS) guidance addresses the DOD-wide problem of Automatic Test Equipment (ATE) proliferation by establishing a requirement for a standard family of ATE in each Service that is based on non-proprietary open-architecture hardware and software. Policy requirements for ATS management are described in Navy Instructions and Army Regulations and DA PAMs. These guidance publications...
This article describes the methods and tools to verify the location of nodes in wireless sensor networks. Software product that allows to analyze the positioning based on the distance with different algorithms is proposed. As a result of simulation the next statistical output variables are defined: percentage of nodes, which have position determined; minimum, maximum and average error in assessing...
This paper introduces xDCI, a Data Science Cyber-infrastructure to support research in a number of scientific domains including genomics, environmental science, biomedical and health science, and social science. xDCI leverages open-source software packages such as the integrated Rule Oriented Data System and the CyVerse Discovery Environment to address significant challenges in data storage, sharing,...
In the next future, IoT systems will be “ubiquitous” and “pervasive”, bringing several benefits to mankind and also many issues about interoperability, security and privacy. The intrinsic vulnerabilities of IoT devices, with limited resources and heterogeneous technologies, together with the lack of specifically designed IoT standards, represent a fertile ground for the expansion of specific cyber...
A new turn in information revolution contributed to the formation of a new universal identity of the uniform postindustrial society. We refer to this phenomenon as the concept of a “New axial period”. The system of education, like all cultural institutions, turned out to be not ready for such a breakthrough in creating a new reality that entails certain problems. Among the problems are: pedagogical...
Process of detailed testing and verification of all automotive embedded software components generates detailed reports about each segment of tested electronic control units (ECU). The very first group of tests in this process is Acceptance tests, and one of the most important tests in this stage of testing and verification is interface check of the software component. The interface check must ensure...
In a service computing environment, Web service is maintained by various stakeholders including content providers, users and integration vendors of the service computing environment. These stakeholders make decisions about software/product license structure and billing system of services they are involved in. Service computing environment can be regarded as being provided and maintained as a synthesis...
The work is focused on intellectualization of the development process of integrated expert systems basing on the the problem-oriented methodology and AT-TECHNOLOGY workbench. Basic intelligent software environment components like intelligent planner, reusable components, standard design procedures are described. Development process with use of intelligent technology is reviewed. An example development...
Certification compliance check for airborne software is very critical as it aids in the certification of the software. Since this compliance check is performed manually which is time-consuming and erroneous, an in-house developed Certification Compliance Tool (CCT) helps in checking the compliance as per RTCA DO-178B/C and generate artifacts depicting the magnitude of compliance. In order to generate...
