Trust is an essential ingredient for commercial success on the Web. “Shopping aggregator” websites such as eBay provide a mechanism for measuring trust in the vendor in the form of online shoppers' positive feedback ratings. This real-world experiment conducted on eBay demonstrates that although coupled with a very high trust rating, the inclusion of an explicitly sexual illustration in shoppin...

Energy consumption and security has become a primary concern in a Wireless Sensor Network. In multi-hop communications, nodes that are near a sink tend to become congested as they are responsible for forwarding data from nodes that are farther away. Thus, the closer a sensor node is to a sink, the faster its battery runs out, whereas those farther away may maintain more energy. This leads to no...

In RSS aggregator, the important issue is how to make the feeds information more manageable for RSS subscriber. In this paper, we propose a suffix tree based RSS feeds document clustering in Chinese RSS aggregator. We construct a suffix tree with meaningful Chinese words, and choose the phrases with high score given by a formula as document features. We cluster document using group-average algo...

To respond to volatility and congestion in the power grid, demand response (DR) mechanisms allow for shaping the load compared to a base load profile. When tapping on a large population of heterogeneous appliances as a DR resource, the challenge is in modeling the dimensions available for control. Such models need to strike the right balance between accuracy of the model and tractability. The g...

Plug-in Electric Vehicles (PEVs) are a rapidly developing technology that can help to reduce greenhouse gas emissions and our dependence on foreign oil. PEVs will also be an integral part of the future smart grid, due to two main features: First, PEV charging stations will most likely be available at home and at work, offering flexible charging options. Second, these vehicles will have the capa...

Data aggregation is commonly used method to reduce communication overhead in wireless sensor networks by combining data received from different sensors and by removing redundancies. The intermediate nodes perform data aggregation task called aggregator nodes. In open and hostile environment aggregator nodes are target for attackers to falsify the aggregation result, and base station accepting i...

In wireless sensor network, in-network data aggregation can eliminate redundancy, improve data accuracy and thus prolong the lifetime of network. However, most of data aggregation technologies assumed that the aggregator node has been receiving all the data when it performers the aggregation operation, these methods give larger latency to the transmission of network's data and affect the accura...

We characterize three classes of demand systems, all of which are defined non-parametrically: homothetic demand systems with a single aggregator (HSA), those with direct implicit additivity (HDIA), and those with indirect implicit additivity (HIIA). In HSA, all the cross-price effects are captured by one price aggregator, while in HDIA and in HIIA, they are captured by two price aggregators. Ea...

We propose a multidimensional approach to regional inequality as an alternative allocation mechanism for EU Structural Funds remittances based on per capita GDP, particularly after EU enlargement. The indicators of regional inequality are combined to a composite index by means of Maasoumi’s aggregator function. We propose Partial Common Principal Component Aanalysis as the estimator of the weig...
