The RODIN-project, which seamlessly integrates experimental, industrial and theoretical work, is organized around the concept of suspended single-and few-layer graphene nanostructures and annealed diamond-like carbon films. These structures are ideal for accessing and engineering the intrinsic material properties of graphene. In particular we will focus on engineering and measuring the mechanical and electromechanical properties. This will be done through sculpting of the suspended structures to desired shapes as well as using thermal post-processing methods. Initially, the graphene will be obtained using standard prototype techniques such as exfoliation and plasma assisted chemical vapor deposition. The main goal of the project, one that requires going beyond the current state of the art in multiple areas and has rapid and substantial industrial impact, is the fabrication and demonstration of a tunable graphene resonator with electronic readout. The performance of a mechanical resonator depends sensitively on materials quality, which makes it an ideal test application for a materials-oriented project.

The problem of optimal scheduling of multicast traffic in time-varying wireless networks is studied in the framework of utility maximization. Since the wireless channel cannot be known exactly, only scheduling policies that take decisions based on a possibly inaccurate estimate of the wireless channel state are considered. A stationary, on-line, gradient-based scheduling and rate control policy is introduced which identifies at every decision instant the sources that should access the wireless medium along with their respective transmission rates. Furthermore, in the case that more than one optimal rate allocation is possible, the one that requires the minimum sum-power expenditure is selected by the policy. The optimality of the proposed policy among all policies that have access to the same estimate of the current wireless channel state is established through stochastic approximation arguments. © 2011 IEEE.

The interface for a capacitive 2-axis micro-gyroscope is implemented in a 0.35-μm HVCMOS technology with a total area of 4.3 mm;2. The ASIC comprises the complete analog interface electronics for the gyroscope, while the focus of the design is in maintaining low supply current and in reducing the chip area. The paper reports the design of reference circuits, high-voltage generation, drive-loop and the capacitive open-loop readout circuits. The prototype sensor that is measured is assembled by directly wire-bonding the stacked dies comprising the interface electronics and the sensor element. The noise floors of the two sensors are 0.028°/s/√Hz for z-axis and 0.032°/s/√Hz for y-axis. The supply current of the chip is 2.2 mA from a 3 V-supply. © 2011 IEEE.

Expert Systems with Applications | Year: 2012

This paper considers an embedded fuzzy expert system for non-feedback uplink power control of wireless local area networks (WLANs). The main idea is to minimize the transmission power of the nodes while keeping the transmission errors at an acceptable level. In the developed method, receivers collect signal strength values which are used by the control systems to define an acceptable transmission power level. The functionality of the proposed solution is demonstrated with simulations, which prove that the use of the expert system to open-loop systems can significantly decrease transmission power, increase energy efficiency and decrease interference to adjacent access points and associated nodes. © 2012 Elsevier Ltd.

The paper explores delay-based congestion and flow control and the offloading of real-time traffic from wireless local area networks (WLANs) to mobile cellular networks (MCNs) in multihomed devices. The control system developed is based on an embedded hierarchical expert system. It adjusts transceivers' traffic flow(s) for prevailing network conditions to achieve application-dependent delay and throughput limits. In wireless networks, delay and throughput depend on the packet size, packet transmission interval, and node connection density. Therefore, the controller on the destination node monitors average one-way delay and the change of one-way delay of the incoming traffic. On this basis, it adjusts the packet size and transmission interval of the source node by transmitting a control command to the source. If the prevailing level of traffic in the network exceeds its capacity despite of the control actions taken, devices prepare for developed asynchronous offloading of traffic to another access network. The control model was validated via simulation of Voice over Internet Protocol (VoIP) traffic in the OMNeT++ network simulator. The results demonstrate that the expert system developed is able to regulate packet sizes to match the prevailing application-dependent optimum and transfer traffic to another network if the network exceed its capacity no matter the control actions taken. Although this work is motivated mainly by issues of congestion and flow control of WLAN systems and the simulations and results were prepared for the IEEE 802.11b system, the approach and techniques are not limited to these systems, but they are applicable for other packet switched access networks (PSANs), too. © 2014 Elsevier Ltd.

The Internet of Things (IoT) is assumed to be an integrated part of Future Internet. IoT can be regarded as an extension of the existing interaction between humans and applications through the new dimension of 'Things' communication and integration. IoT networks in the scale of million nodes are possible even today but managing the nodes and information provided by large networks beyond that scale requires architecture scalability that is still an area to explore. The aim of this paper is to present usage scenarios and analyse requirements of a Mobile Cellular Network (MCN) based router for a secure, energy efficient, and scalable wireless network architecture. The network is composed of the MCN based edge routers and large amount of Central Processing Units (CPU), memory, and energy restricted sensor/actuator devices. Mobile routers communicate with application servers in the Internet and surrounding sensor network(s). The analysis of the scenarios highlighted common aspects and led to requirements that were used to define the MCN based router/proxy device and guide the network and system architecture design as well as the development of a prototype. © 2013 IEEE.

Editor’s note: Mitch Lazar is CEO of Taptu. He Founded CNN and Cartoon Network Mobile. He was a former journalist at CNN and one of the co-founders of CNN.com. Prior to joining Taptu, Mitch headed Yahoo! Mobile Europe. Staying on top of your game and understanding the competitive landscape is essential to winning in the modern business world. A huge component to staying ahead of the curve is keeping a close eye on competitors in your market, which entails maintaining a watchful eye on industry news. Some companies turn to expensive news monitoring services to keep track of their respective industry, but in reality there are more viable options. Emerging tablet news and information services like Flipboard, Pulse and others are proving an incredible companion to business and consulting executives in staying current with industry changes occurring around them. Jeff Cavins, CEO of Fuzebox, recently wrote in Business Insider that the explosive uptake of tablet computers is fueling the growth of what he called the new “iPad economy.” Cavins said: “The iPad is shifting the way businesses function, changing how executives interact and transforming the economics of today’s business operations.” The iPad economy is a growing reality across the globe, and businesses are turning to enterprise apps to help them succeed. Simple RSS readers are used to condense multiple streams of content from a variety of sources into single channels, granting users access to diverse content all in one place. Some applications have further simplified news aggregation by using innovative search technology that goes beyond the function of RSS readers to deliver richer streams of highly targeted information to business users – a critical asset to businesses large and small. Improved search and filtering techniques make it simple and easy for a business to set up a Web-monitoring service. Google News and Google Alerts were an early step in the right direction, but anyone who monitors news on a daily basis knows that these services don’t always give you the news you want when you need it. As users continue to adopt tablets as a primary reading outlet, there is a huge opportunity to create real-time, targeted news experiences. Apps like Zite, which was bought by CNN in 2011, aim to learn about users’ interests through the stories they read, and provide related content based on those preferences. News-reader apps give users the power to create their own streams of content based on keywords to offer analysis of the topic across any genre of content, keeping them constantly updated in the ever-changing world of business. Recently we have seen innovative companies like Wavii launch to further personalize the way users get their news, and as this vertical continues to mature, we should see more sophisticated technologies making their way onto tablets. By utilizing apps that filter and search, tablets are changing the way news is channeled and consumed. Best of all, once streams are set up, they can be shared business-wide or between colleagues so the wheel never has to be re-invented. Touting efficiency, news-readers give users the opportunity to scan hundreds of articles in a few moments and immediately delve deeper into the most interesting content. News-reading services do all the heavy lifting by aggregating the stories that match your interests, giving you more time to spend reading the news you care about rather than searching for it. The same way Evernote helps you save your daily thoughts and ideas all in one spot, news-readers concisely track what’s going on in every field that interests you. Beyond increasing efficiency, news-readers also allow for easy sharing of any stories of interest with your community of colleagues or friends. Every blog and news site has its own way to share stories you enjoy with friends, but they are not always convenient for users. Tablet apps make sharing simple, while still driving traffic back to the original source. When browsing a vast number of stories every day, it’s often hard to keep track of the important ones, or to flag them down once you’ve flipped past. Easy in-app bookmarking tools such as Pocket or Instapaper make for a better overall experience because returning to a piece of interesting news is simple. Creating your own playlist through bookmarks is intuitive, as is sharing that list with colleagues, which is an asset for group collaboration. Apps are abundant, but the ones with the potential to make a difference to the business world are those that improve productivity, efficiency and knowledge sharing. Discovering and utilizing these gems in a marketplace that has become a sea of apps is a difficult task. Apps like news readers set themselves apart by providing essential tools for businesses and adding value to help them win in their respective vertical.
