This instalment of the Impact department questions the impact of software growth and asks whether it's possible to innovate constructively without seriously disrupting the balance of our society.
Multiprocessor SoCs (MPSoCs) are deployed in intelligent Rear View Camera Systems (iRVCS) for capture, analytics and display. iRVCS, mounted near the car's exterior surface, are subject to direct sunlight for prolonged time. At high junction temperatures (Tj) iRVCS completely shuts down for thermal protection resulting in complete loss of visibility. The paper focuses on techniques to detect such...
This paper describes smart converters and presents results from real industrial application. The auxiliary converters in public transport vehicles are very important part of vehicles. The auxiliary converters consist from three-phase, inverters, single-phase inverters, chargers, power supplies of several different voltages. Nowadays converters contain powerful digital signal processors (DSP) with...
Continuous Deployment is an important enabler of rapid delivery of business value and early end user feedback. While frequent code deployment is well understood, the impact of frequent change on persistent data is less understood and supported. SQL schema evolutions in particular can make it expensive to deploy a new version, and may even lead to downtime if schema changes can only be applied by blocking...
This paper provides an overview on the software architecture used for the realization of cooperative behavior of heterogeneous marine robots. The work was performed within the European Research Project MORPH (FP7-ICT-288704) which strived for the solution to ocean mapping missions over harsh environments like vertical and overhanging cliff walls by employing a team of different unmanned marine crafts...
This paper presents a novel idea for reducing the data storage problems in the self-driving cars. Self-driving cars is a technology that is observed by the modern word with most curiosity. However the vulnerability with the car is the growing data and the approach for handling such huge amount of data growth. This paper proposes a cloud based self-driving car which can optimize the data storage problems...
This paper deals with the design of a safety-critical embedded system for railroad vehicles usually referred to as "dead-man's vigilance device" (DMVD). A DMVD monitors the activity of the operator driving a train to detect his/her possible incapacitation while the vehicle is traveling. The system relies on a redundant and diverse FPGA-based architecture (without using micro-controllers,...
Cyber-physical systems typically involve a large number of mobile autonomous devices that closely interact with each other and their environment. Standard design and development techniques from the embedded domain fail to accurately model the dynamics of such systems and, hence, there is an increasing need for new programming models and abstractions. Component-based design approaches are a promising...
The growing complexity of embedded systems software entails new development techniques. Component-Based Software Engineering is undoubtedly suitable for the development of complex systems thanks to its inherent component reuse. Another approach to reduce software complexity is by partitioning the system behavior into different operational modes. Each mode is associated with a unique behavior and the...
Service recovery technology is an important constituent part of the emergency response technologies. The service recovery goal is to build a technology system of service recovery focusing on the survival of information system services. By analyzing the relationship between service and data, we present a service recovery mechanism by recovering service's data. We introduce a third party service monitor...
Automotive Electronic Control Units (ECUs) are usually the most complicated and powerful embedded systems in an automobile. Verification and validation of these ECUs poses challenges due to exponential growth in the size and complexity of ECUs's software. This paper provides a new functional complexity metric that can be derived from the specification and can be used to estimate the total number of...
This paper presents a heterogeneous network interconnection model based on a kind of translucent routing gateway and Linux virtual device to tackle with the communication issue about heterogeneous communication between various devices and Internet in the vehicular networks. In this model, an in-vehicle CAN node is regarded as a usual node in the Internet and will be assigned an IPv6 address and a...
GSM based security system are much more stout then an ordinary security system. The ordinary systems are simply based on the concept of sensors. They sound an alarm on detecting movement. This system of technology has now lost its appeal as it has become a common sighting in metros where these alarms go off unnecessarily. We proposed with GSM techniques and a better decision making process is built...
The AUVSI Autonomous Surface vehicle event is a student-based competition where teams design, build and compete with fully autonomous surface vessel. These vehicles are required to preform many different tasks that vary from competition to competition but the ability to navigate channels marked by red and green markers and perform GPS based navigation is always a constant. Embry-Riddle Aeronautical...
Cyber-physical systems bridge the gap between cyber components, typically written in software, and the physical world. Software written with traditional development practices, however, likely contains bugs or unintended interactions among components, which can result in uncontrolled and possibly disastrous physical-world interactions. Complete verification of cyber-physical systems, however, is often...
The information from bus sensors is not able to perform on the in-vehicle meter directly because original information is not compatible with transmitting. To overcome this challenge, the authors designed a meter information module (MIM), whose fundamentals were collecting, processing and sending signals. The MIM chose Freescale's HCS12 Microcontroller Unit (MCU) as its core component and Controller...
In accordance with the calibration requirements of special vehicle, an automatic calibration system is developed based on PXI bus and GPIB bus. Based on bus technologies, this common calibration platform realizes the result that one platform with a variety of calibration function. The hardware of calibration system is designed based on the measurement requirements. The corresponding software system...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
This paper describes how we can use existing mobile technology to track the vehicle. Here the embedded system along with the mobile is used to prevent the vehicle from being stolen and also if the vehicle is stolen then its location can be tracked. Mobile technology is the fastest growing communication mode. In todaypsilas mobile technology we all are acquainted with short message service (SMS). In...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
