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)
Hereditary spastic paraplegia (HSP) is a very heterogeneous disease, both genetically and clinically. To date, approximately 52 loci and 31 genes have been reported to be involved in the causality of HSP. The pattern of inheritance of the disease can be autosomal dominant, autosomal recessive, or X-linked recessive. Autosomal recessive HSP with thin corpus(More)
Grifola frondosa (Dicks.) Gray is a widely consumed edible and medicinal fungus, Ancient books record that it can boost qi and fortify the spleen, moisten the lung and protect the liver. Modern people mainly use it to assist in the treatment of diabetes mellitus and various cancers. Over the past three decades, G. frondosa polysaccharides were shown to(More)
Based on remote sensing images and geographic information system, and by using landscape metrics and Kappa coefficient, this paper studied the farmland landscape change in Wenchuan County of Minjiang River upper reach. A logistic regression model was used to analyze the driving forces of this change, with elevation, gradient, aspect, and the distances to(More)
In various conditions of blood demand of circulatory system, the autonomic regulations system of body regulates the heart rate (HR) to maintain the arterial pressure (AP) constant, where the HR is considered as the controlled variable indicating the blood demands of the circulatory system. Therefore, model-free adaptive controller is used to regulate the(More)
Because of the special structures of intraaorta pump, the pressure and blood flow sensors cannot be implanted in the blood pump. Moreover, the cardiovascular pump is a very complex system that has no accurate model but much uncertainty and disturbance. Hence, the conventional control algorithm cannot achieve good performance. To overcome this problem, on(More)
