Abstract
The IT industry is investing in technologies to support the transition form distributed dedicated IT infrastructure to a centralized hosted cloud computing service. The promises of cloud computing includes the reduction for IT capital costs, access to dynamically scalable server resources and infinite storage capacity. For many businesses this transition has not been successful, as connectivity to the cloud has dramatically limited the capabilities of a cloud service offering. Utilizing best effort Internet for cloud connectivity has had a negative impact on application responses and bring into question the security of corporate information. To address these challenges investment are being made into a new class of connectivity services, namely Carrier Ethernet. This technical talk will review some of the key communication technologies that have been developed to enable a reliable and secure transition to cloud computing services.

ICT is becoming one of the main culprits for CO2 emissions, already on a par with air travel since 2007. Energy consumption by ICT is estimated to increase by 4% a year, despite the increasing energy efficiency of electronic and computer equipment, due to the ever increasing usage of computers and telecommunications. On the positive side, ICT offers the potential to manage energy more efficiently, help better match energy supply and demand, and dynamically substitute renewable energy sources in the place of fossil fuels. At the same time, one would like to think that ICT is saving energy and CO2 emissions in other areas (such as transport), by substituting on-line activities for physical activities, such as working at home rather than commuting to an office. But such trends are difficult to identify, while the recent economic crisis in Europe and the USA has definitely had an impact on energy consumption in industry and other fields of activity. Within ICT itself, communications represent close to 25% of energy consumption, with data centres accounting for another 20% or so, the rest being attributed to PCs, terminal devices and office equipment including local networks. This lecture will focus on the ICT aspects of energy consumption from a performance engineering perspective, and show how some of our established methods, with measurements, can be used to understand the trade-offs between QoS and energy consumption, and help reduce the energy consumption in servers and networks.

This is a presentation that introduces the NASA Debris Radar (NDR) system developed to characterize debris liberated by the space shuttle (and any follow-on rocket system) during its ascent into space. Radar technology is well suited for characterizing shuttle ascent debris, and is especially valuable during night launches when optical sensors are severely degraded. The shuttle debris mission presents challenging radar requirements in terms of target detection and tracking, minimum detectable radar cross-section (RCS), calibration accuracy, power profile management, and operational readiness. After setting the stage with background of the Columbia accident, I initially describe the NDR system consists of stationary C-band radar located at Kennedy Space Center (KSC) and two X-band radars deployed to sea during shuttle missions. Various sizes, shapes, and types of shuttle debris materials were characterized using static and dynamic radar measurements and ballistic coefficient calculations. My second Part discusses the NASA Debris Radar (NDR) successes, which led to a new challenge of processing and analyzing the large amount of radar data collected by the NDR systems and extracting information useful to the NASA debris community. Analysis tools and software codes were developed to visualize the shuttle metric data in real-time, visualize metric and signature data during post-mission analysis, automatically detect and characterize debris tracks in signature data, determine ballistic numbers for detected debris objects, and assess material type, size, release location and threat to the orbiter based on radar scattering and ballistic properties of the debris. Future applications for space situational awareness and space-lift applications will also be discussed.

Terahertz (THz) technologies aim to address the largely underdeveloped and almost unexploited electromagnetic spectral range between 1 and 10 THz (1012 – 1013 Hz), which lies between visible/infrared optical bands and radio-frequency (RF)/microwave frequencies. With a much higher carrier frequency than RF/microwave, the unlicensed terahertz band holds great potential for next generation high-speed wireless communications, such as secured short-link communications, local access network connections, and high-speed wireless communications. Terahertz radiation could also be used for other important applications, such as THz spectroscopy, atmospheric pollution monitoring, global warming, medical and biological research, THz imaging for detecting concealed weapons or currency forgeries at airports or security check points as well as THz Radar for spotting roadside bombs over a short distance. Despite these identified and wide-ranging applications, deployment of THz technologies has largely fallen behind that of electromagnetic technologies at optical (visible/infrared) and RF/microwave frequencies. Progress towards viable THz applications has been hampered by the lack of suitable and enabling components, such as emitters and detectors. In this talk, I will present novel THz devices – THz quantum cascade lasers (QCLs) [1] and THz quantum-well photodetectors (QWP) – which are based on intersubband transition in semiconductor quantum structures for wave generation and detection, respectively. In collaboration with the National Research Council (NRC), we employed a combined theoretical and experimental approach, including numerical simulations based on a simple density matrix model and state-of-the-art molecular beam epitaxy growth and device fabrication, and demonstrated a new world record of the maximum lasing temperature of 199.5 K for THz QCLs in 2012 [2]. I will also report our other recent research progress, including the oscillator strength effects on THz QCL device performance, the many-body effects in THz QWP, and new active region design based on phonon-photon-phonon relaxation for THz.

ABSTARCT:
Wireless communications signals have evolved greatly over the past century, from the use of Morse Code to very complicated digital modulation schemes used in wideband CDMA (WCDMA) and 3GPP Long-term evolution (LTE). This progression challenges the design of transmitters to be simultaneously energy efficient, low distortion, and spectrally clean. The increasing peak-to-average power ratio (PAPR) characteristic of these signals is a particular problem. Because it is important to understand why this is happening this presentation begins with a discussion of the physical implications of Shannon’s Capacity Limit combined with the Fourier Transform.
A ‘backwards’ design perspective is then presented, where we begin design from a maximally energy efficient circuit (a switch) and then make it generate the required signals, instead of the conventional approach of beginning with linear circuitry and then finding ways to improve its energy efficiency. This directly leads to the design and implementation of polar-modulation to improve both the energy efficiency of the power amplifier and effective linearity of the transmitter. Design of intentionally compressed circuitry is very different from conventional linear amplifier techniques, and these new design techniques will be discussed..
