Clutch-to-clutch shift technology is a key enabler for fast and smooth gearshift for multi gear transmissions. However, conventional hydraulic actuation systems for clutches have drawbacks of oil leakage and low efficiency. Electromechanical devices including wedge mechanism offer potential alternative actuators. The previous studies on the wedge emphasize on self-reinforcement, but neglect self-weakened...
Recent advances in technologies have allowed the design of small-size low-power and low-cost devices that can be connected to the Internet, enabling the emerging paradigm of Internet-of-things (IoT). IoT covers an ever-increasing range of applications, e.g., health-care monitoring, smart homes and buildings, etc. In this invited paper, we discuss and summarize the IoT paradigm with a special focus...
With the proliferation of portable and mobile IoT devices and their increasing processing capability, we witness that the edge of network is moving to the IoT gateways and smart devices. To avoid Big Data issues (e.g. high latency of cloud based IoT), the processing of the captured data is starting from the IoT edge node. However, the available processing capabilities and energy resources are still...
Emergence of Internet-of-Things brings a whole new class of applications and higher efficiency for existing services. Application-specific requirements, as well as connectivity and communication ability of devices have introduced new challenges for IoT applications. This paper provides an overview of IoT technologies required from an embedded design perspective and specific properties associated with...
Internet-of-Things (IoT) envisions an infrastructure of ubiquitous networked smart devices offering advanced monitoring and control services. Current art in IoT architectures utilizes gateways to enable application-specific connectivity to IoT devices. In typical configurations, an IoT gateway is shared among several IoT devices. However, given the limited available bandwidth and processing capabilities...
Technology advancements as well as the Internet-of-Things paradigm enable the design of wearable personal healthcare monitoring systems. Ultra-low-power design is a challenging area for these battery-operated wearable devices, where the energy supply is limited and hardware resources are scarce. Some biomedical applications tolerate small errors in the values of the biosignal or small degradation...
Modern FPGA-based platforms provide multiple clock domains and their frequencies can be changed at runtime by using PLLs and clock multiplexers. This is especially beneficial for platforms that run several applications simultaneously (e.g. modern wireless sensor nodes that are shared by multiple users), as different processing modules may be fed by different clock frequencies at different time windows...
Wireless sensor networks have become shared resources providing sensing services to monitor ambient environment. The tasks performed by the sensor nodes and the network structure are becoming more and more complex so that they cannot be handled efficiently by traditional sensor nodes any more. The traditional sensor node architecture, which has software implementation running on a fixed hardware design,...
The purpose of this study is to demonstrate, with experiments and with computer simulations based on a firm chromatographic theory, that the wide spread perception of that the United States Pharmacopeia tailing factor must be lower than 2 (T f <2) is questionable when using the latest generation of LC equipment. It is shown that highly efficient LC separations like those obtained with sub-2μm...
In this work we study control independence in embedded processors. We classify control independent instructions to data dependent and data independent and measure each group's frequency and behavior. Moreover, we study how control independent instructions impact power dissipation and resource utilization. We also investigate control independent instructions' behavior for different processors and branch...
