We propose a column-based split cell-VSS (CS-CVSS) data-aware write-assisted (DAW A) 9T ultra-low voltage SRAM with enhanced read sensing margin in 28nm FDSOI technology. The proposed write-assist technique (CS-CVSS and DAWA) improve both half-select SNM and write margin. The proposed 3T low leakage read port enhances read sensing margin by minimizing bitline leakage through negative gate to source...
Compared to conventional processors, stochastic computing architectures have strong potential to speed up computation time and to reduce power consumption. We present such an architecture, called Bayesian Machine (BM), dedicated to solving Bayesian inference problems. Given a set of noisy signals provided by low-level sensors, a BM estimates the posterior probability distribution of an unknown target...
Current solutions for sensor-cloud integration do not offer tools or platforms providing both efficient data management and standardized interfaces for the development of WSN-based applications on a shared infrastructure. This paper proposes a new architecture based on the paradigm of Service-Oriented Computing and virtualization of sensors for efficient management of heterogeneous WSNs data. The...
Hardware-in-the-Loop Simulation is being increasingly used in verification and validation of embedded computer systems; as well as for rapid prototyping and validation of models. The numerous benefits of this technique and the possibility of widespread use is hindered by the high cost of the necessary infrastructure. The proposed solution is based on a PC executing the plant simulation and connected,...
In this paper, we propose and evaluate the application of unsupervised machine learning to anomaly detection for a Cyber-Physical System (CPS). We compare two methods: Deep Neural Networks (DNN) adapted to time series data generated by a CPS, and one-class Support Vector Machines (SVM). These methods are evaluated against data from the Secure Water Treatment (SWaT) testbed, a scaled-down but fully...
In the age of Internet of Things (IoT), sensors form a foundational component of IoT services, yet they are rigid with little capability for programmable configuration or reusability as they are application-specific, manufacturer-specific. Emerging IoT applications often deploy a vast number of sensors which may serve multiple applications. Programmability is thus essential but not found in legacy...
Smart city has been advanced much from the conceptual model to the actual construction stage. This paper takes Nanhai as an example to demonstrate how to manage the resources of IoT as a whole and plan the top-level design of IoT development and smart city. After analysis of Nanhai IoT status, a general framework of Nanhai IoT development is proposed as the top-level design using five architectures...
Smart grid software integrates various software components in Generation, Transmission, Distribution, Smart Metering and Cloud systems. The smart grid architecture is evolving with new features and to accommodate legacy software elements. Smart grid integrated software is an evolving approach in line with modern Information and Communication technology. In this paper, the authors propose a software...
The challenge of failure management emerges in decentralized architectures due to the distributed nature of the layered control process. Failures in microgrid system may occur at the microgrid level or any of the control layers. A failure detection and response mechanism is required to attain a reliable, fault-tolerant microgrid operation. This paper introduces a Failure Management Unit as an essential...
The increasing complexity of automotive software systems and the desire for more frequent software and even feature updates require new approaches to the design, integration and testing of these systems. Ideally, those approaches enable an in-field updatability of automotive software systems that provides the same degree of safety guarantees as the traditionally lab-based deployment. In this paper,...
E-health is one of the domains which will need more and more IoT solutions in the future, as it requires short delays for life-dependency situations and safe local storage spaces for privacy matters. The emergency context demands efficient communication and computing capacities, and the cloud vision as well as traditional TCP/IP way of communication cannot really suit these requirements. New approaches...
eHealth is a technology that is growing in importance over time, varying from remote access to Medical Records, such as Electronic Health Records (EHR), or Electronic Medical Records (EMR), to real-time data exchange from different on-body sensors coming from different patients. With this huge amount of critical data being exchanged, problems and challenges arise. Privacy and confidentiality of this...
During recent years, we have witnessed an explosion in the Internet of Thing (IoT) in terms of the number and types of physical devices. However, there are many limitations of these devices regarding their computing power, storage, and connection capabilities. They affect on-device processing of sensed data significantly. Centralized treatment of IoT data has proven challenging for many use cases...
Poor air quality in urban areas is becoming an important problem that needs to be addressed. This paper presents the system architecture of project Urb@nEcoLife for compilation of environmental data using low-cost data sensors. Although there are several proposals dealing with sensor networks, most of them focus on solving partial problems. Urb@nEcoLife is a comprehensive proposal that develops a...
Software Defined Networks (SDN) has been attracting various researchers from both academia and industry to enhance the current ICT stakes and networking paradigm. The beauty of SDN is the division of Control and Data planes and make it easy for the engineers to modify the networking protocols without visiting onsite devices. Similarly, Smart Cities concept has been coined recently, where a plethora...
During the development and expansion of Internet of Things (IoT), main challenges needing to be addressed are the heterogeneity, interoperability, scalability, flexibility and security of IoT applications. In this paper, we view IoT as a large-scale distributed cyber-physical-social complex network. From that perspective, the above challenges are analyzed. Then, we propose a distributed multi-agent...
Edge computing is an increasingly popular paradigm, wherein computation comes closer to the sources of data. A key challenge for edge computing is discovering and utilizing the heterogeneous resources of the vast number of mobile devices at the network edge. Mobile edge devices hide behind private networks, they are mobile and their owners hesitate to share them due to privacy considerations. We propose...
In the mobile internet era, location-based services have been widely used in mobile applications for delivering novel services to end-users.

This paper proposes and analyzes the use of the Arduino Zero board as the lab platform for the Computer Structure course that constitutes an essential part of Computer Science studies. The understanding of the main functional blocks of a computer, addressing the main concepts included in the course syllabus, is reinforced by mean of the hands-on experience acquired in the lab sessions and the completion...
Shorter innovation cycles along with the demand for individualized, high-quality products pose high challenges on today's automated material flow systems. These systems, suitable for producing bulk goods, but inflexible in case of product changes, need to react flexibly to unplanned configurations. Especially in the software domain retroactive adaptations are tedious work and prone to errors. By deploying...
