This paper presents a supply system design methodology for high-speed interface systems used in the design of a 1600 Mbps DDR3 interface in wirebond package. The high data rate and challenging system environment requires a system-level approach of supply noise mitigation that demonstrates the full spectrum of Power Integrity considerations typical in the design of high-speed interfaces. We will...

Due to the wind speed variation, wind shear and tower shadow effects, grid connected wind turbines are the sources of power fluctuations which may produce flicker during continuous operation. This paper presents a model of an MW-level variable speed wind turbine with a doubly fed induction generatorto investigate the flicker emission and mitigation issues. An individual pitch control (IPC) stra...

Femtocell networks, consisting of a conventional macro cellular deployment and overlaying femtocells, forming a hierarchical cell structure, constitute an attractive solution to improving the macrocell capacity and coverage. This paper treats the uplink interference problem in orthogonal frequency-division multiple-access (OFDMA)-based femtocell networks with partial cochannel deployment. First...

Air pollutants such as tropospheric ozone and black carbon (soot) also contribute to the greenhouse effect. Black carbon is thought to be the second or third most important anthropogenic contributor to global warming, while troposheric ozone is the fourth most important. Both are also major components of indoor and outdoor air pollution. This paper reviews the existing literature of the health,...

Human-elephant conflict (HEC) threatens the survival of endangered Asian elephants (Elephas maximus). Translocating "problem-elephants" is an important HEC mitigation and elephant conservation strategy across elephant range, with hundreds translocated annually. In the first comprehensive assessment of elephant translocation, we monitored 16 translocations in Sri Lanka with GPS collars. All tran...

Rainfall-triggered landslides are part of a natural process of hillslope erosion that can result in catastrophic loss of life and extensive property damage in mountainous, densely populated areas. As global population expansion on or near steep hillslopes continues, the human and economic costs associated with landslides will increase. Landslide hazard mitigation strategies generally involve ha...

This paper considers coordinated user scheduling in a multi-user two-hop multiinput multi-output relay system with limited feedback. The proposed scheme utilizes a quantized transmit correlation and channel quality information, enabling to achieve both interference mitigation and multi-user diversity (MUD) gain. To this end, we first investigate the effect of quantization error on the statistic...

A case study comparing extensive, low-yielding smallholder maize production with an intensified, high-yielding production system (‘sustainable intensification’) is used to illustrate potential trade-offs between agricultural product carbon footprints (PCFs) and land use (LU). In the comparative analysis the extensive systems had lower PCFs so the conclusion may be that these systems should be e...

The provision of alternative water sources is the principal arsenic mitigation strategy in Bangladesh, but can lead to risk substitution. A study of arsenic mitigation options was undertaken to assess water quality and sanitary condition and to estimate the burden of disease associated with each technology in disability-adjusted life years (DALYs). Dugwells and pond-sand filters showed heavy mi...

Introduction The use of microalgae-based bio-mitigation (AEN-116) suffers from a range of challenges primarily related to system complexity and scale-up issues that are driven more by economic constraints than technical limitations. It should be noted that only biological carbon capture and recycling has the potential to generate a revenue stream to offset, at least in part, the overall cost of...
