Stacks of dielectric optical films are tailored to generate the third harmonic of femtosecond laser pulses. The improvement of efficiency compared to bulk samples of the same material is a combination of periodic reset of the phase mismatch and field enhancements due to resonant substructures.
Prefix coding of hierarchical categories for publish-subscribe in mobile wireless environments
This paper proposes an algorithm called MACH for coding a hierarchical category structure to enable prefix matching between a publication and a subscription. Compared to fixed-length coding, the MACH algorithm…
Prediction technique for resource allocation in Micro Data Center
Cloud Computing (CC) represents an attractive and cost-efficient of server-based computing and application service provider models. Virtualization technology enables dynamically allocate resources based on workload fluctuations from users' needs. The…
Application of improved core vector machine in the prediction of algal blooms in Tolo Harbour
Support vector machine (SVM) and its derivative algorithms have been increasingly used to predict algal blooms recently. However, its computation complexity remains an annoying problem. To improve the time cost…
Climate condition that mostly affects the change of tweet content
Climate condition affects users' action and tweet content. We discover that temperature and humidity affects users' action more than the general weather category such as sunny or rainy. In detail,…
Ultimate control and security over data localization in the cloud
Cloud Computing has attracted much attention recently with all its benefits in providing data availability anytime, anywhere, on any device. The end of this decade is marked by a paradigm…
Word Sense Disambiguation Based on Feature Ranking Graph
Research in the field of WSD has been conducted in computational linguistics as a specific task for many years. Language and context features have been shown to be very helpful…
OPF: Open Preference and Feature recommender system
This paper presents an open recommender system to ease the entering barriers due to lack of sufficient background knowledge for small or new service providers. The proposed Open Preference and…
BlueFall: Testing swarming protocols through mobile phones
In recent years, the number of appliances connected to the Interned has steadily increased thanks to the wide popularity of WiFi/3G enabled mobile devices. This has led to an increase…
Encrypted Gradient Descent Protocol for Outsourced Data Mining
With the push of cloud computing which has both resource and compute scalability, data, which has been exploding in the past years, are often outsourced to a server. To this…
