Complex systems design requires a time-consuming verification process in support of the safety and maintenance requirements. In this paper, we describe an integrated verification flow of system requirements as well as system fault behaviors and fault-tolerant properties. The process converts XML-based architectural descriptions into SystemC simulation modules tied to predefined libraries. Flexible...
This study looks at the need for a device that monitors upper extremity movements. The device needs to be able to predict gestures on-board to provide immediate feedback. Linear Discriminate Analysis and Support Vector Machine Light and Support Vector Machine Multiclass libraries were implemented on an Atmel embedded system to investigate the limitations. For the Support Vector Machine Light implementation...
The high performance computing landscape is filled with diverse hardware components. A large part of understanding how these components compare to others is by looking at the various environmental aspects of these devices such as power consumption, temperature, etc. Thankfully, vendors of these various pieces of hardware have supported this by providing mechanisms to obtain this data. However, differences...
The software architecture of smart learning environment can be perceived as an environment that is equipped with various audio-visual objects to capture human motion, utterance and gesture, allowing the teacher to deliver lectures to both local and remote audience through the Internet. The interactive objects in such architectural environment are interfaced with simple navigation, depending on operation...
As the number of smart device users has increased, PC-based smart work environments of businesses and public institutions have opted to adopt mobile offices to support their employees. However, with the trend of BYOD (Bring Your Own Device), security problems such as the leaking of confidential information of businesses and important contents have also developed. Thus, the paper proposes utilization...
Smartphones provide applications that are increasingly similar to those of interactive desktop programs, providing rich graphics and animations. To simplify the creation of these interactive applications, mobile operating systems employ highlevel object-oriented programming languages and shared libraries to manipulate the device's peripherals and provide common userinterface frameworks. The presence...
Smart environments represent a relatively uncharted ICT territory where plenty of sensor and actuator devices can be enrolled on-demand in order to realize high value-added services. A few application scenarios, such as Smart Cities, have already been explored. However, in order to finally enable such a paradigm, several issues have to be dealt with. In particular, from a developer perspective the...
Most Wireless Sensor Network platforms — such as the Mica, Iris, and Telos B families of motes — use low-power 8-bit microprocessors which have limited memory and processing capabilities, thus requiring researchers to implement communication protocols and data processing routines using low-level programming practices that are tedious and cumbersome. Rich features available in modern desktop operating...
We present ELIOT, an Erlang-based development framework expressly conceived for heterogeneous and massively decentralized sensing/actuation systems: a vision commonly regarded as the “Internet of Things”. We choose Erlang due to the functional high-level programming model and the native support for concurrency and distributed programming. Both are assets when developing applications as well as system-level...
We present a library of reusable, abstract, low granularity components for the development of novel interaction techniques. Based on the InTml language and through an iterative process, we have designed 7 selection and 5 travel techniques from [5] as dataflows of reusable components. The result is a compact set of 30 components that represent interactive content and useful behavior for interaction...
Due to the increasing advance on wireless communication and sensors, Wireless Sensor Networks (WSN) have been widely used in several fields, such as medicine, science, industrial automation and security. A possible solution is to use CMOS System on Chip (SoC) sensor nodes as hardware platforms due to its extremely low power, sensing, computation and communication capabilities. This work presents the...
Many laboratories and companies are developing a mobile robot with various sensors and actuators. They implement navigation techniques usually tailored to their own robot. In this paper, we introduce a novel robot navigation library, Universal Robot Navigation (uRON). uRON is designed to be portable and independent from robot hardware and operating systems. Users can apply uRON to their robots with...
Cognitive radios are slowly becoming a reality. Besides the need for hardware reconfigurability and the capability to sense spectrum opportunities, adaptability in the MAC designs are required so that the wireless communication systems can support cognitive radio functionalities. In this demo paper, we propose a MAC design framework which enables fast composition of MAC protocols which are best fitted...
Adaptability is a key strategy in the design of effective wireless sensor networks. Communication schemes need to adapt to dynamic topologies and fluctuating traffic rates. Applications have to alter their behavior to respond to mutated necessities or to cope with environmental changes. The network, as a whole, has to tolerate the disappearance of faulting nodes or the appearance of additional ones...
RCA has developed an implementation independent architecture to integrate electrical/electronic subsystems. The architecture described in this paper is easily upgradable and features deep integration, a high degree of modularity and common modules structured around standard interfaces. These features give the architecture a degree of flexibility and technology robustness seldom found in military applications...
