In this paper we present a process model for developing usable cross-cultural websites. Compatible with ISO 13407, the process model documents an abstraction of the design process focusing on cultural issues in development. It provides a framework in which a variety of user-based and expert-based techniques for analysis and design are placed within the(More)
We first provide an overview of some of the latest developments in wireless communications using multiple transmitters and multiple receivers. We point out the importance of SNR control in fast random fading environment. For applications where large antenna arrays are not suitable, we introduce the concept of wireless antennas or wireless relays that are(More)
The behavior of several landscape pattern metrics were tested against various pattern scenarios generated by neutral landscape models, including number of classes, scale-map extent, scale-resolution, class proportion, aggregation level—RULE, and aggregation level—SimMap. The results demonstrate that most of the metrics are sensitive to certain pattern(More)
Aim Predictions of ecosystem responses to climate warming are often made using gap models, which are among the most effective tools for assessing the effects of climate change on forest composition and structure. Gap models do not generally account for broad-scale effects such as the spatial configuration of the simulated forest ecosystems, disturbance, and(More)
For mobile ad hoc networking, relaying is one of the most fundamental functions. The traditional relaying strategy is serial, where data packets hop from a single node to another, and the nodes neighboring a transmitting node or a receiving node are suppressed from transmission to avoid radio interference. We consider a parallel relaying strategy where(More)
For ad hoc mobile networks, parallel wireless relays with space-time modulation have recently been discovered, and their potential to increase network capacity has been found to be significant. In this paper, we provide an analytical study of the diversity factor achievable by two relays with orthogonal space-time modulation. Unlike two transmitters or two(More)
Changbai Natural Reserve in northeastern China provides an excellent opportunity to explore how temperate and boreal forest ecosystems in northeastern China will evolve and recover over large spatial and temporal scales. Such studies are increasingly needed to design scientifically sound forest management and restoration plans in this region. Long-term (300(More)
This work is the first demonstration of electrical modulation of surface energy to reversibly switch dynamic high-speed gas-liquid two-phase microfluidic flow patterns. Manipulation of dynamic two-phase systems with continuous high-speed flows is complex and interesting due to the multiple types of forces that need to be considered. Here, distinct stable(More)
