Title: Bricolage: Example-Based Retargeting for Web Design
Authors: Ranjitha Kumar Jerry O Talton Salman Ahmad Scott R Klemmer
Abstract: The Web provides a corpus of design examples unparalleled in human history. However, leveraging existing designs to produce new pages is often difficult. This paper introduces the Bricolage algorithm for transferring design and content between Web pages. Bricolage employs a novel, structured-prediction technique that learns to create coherent mappings between pages by training on human-generated exemplars. The produced mappings are then used to automatically transfer the content from one page into the style and layout of an-other. We show that Bricolage can learn to accurately repro-duce human page mappings, and that it provides a general, efficient, and automatic technique for retargeting content between a variety of real Web pages.

Title: Fractal behind coin-reducing payment
Authors: Ken Yamamoto , Yoshihiro Yamazaki
Abstract: The minimal payment a payment method which minimizes the number of coins in a purse is presented. We focus on a time series of change given back to a shopper repeating the minimal payment. By using the delay plot, the set of successive change possesses a fine structure similar to the Sierpinski gasket. We also estimate affectivity of the minimal- payment method by means of the average number of coins in a purse, and conclude that the minimal-payment strategy is the best to reduce the number of coins in a purse. More- over, we compare our results to the rule-60 cellular automaton and the Pascal Sierpinski gaskets, which are known as generators of the discrete Sierpinski gasket.

Title: Thermal phenomena associated with water transport across a fuel cell membrane: Soret and Dufour effects
Authors: K Glavatskiy a,n , JG Pharoah b , S Kjelstrup
Abstract: We present calculations of the coupling effects that take place when heat and water are transported across a membrane relevant to fuel cells, using the theory of non-equilibrium thermodynamics. Numerical results are given for the Nafeon membrane bounded by surfaces of molecular thickness in contact with water vapor of varying relative humidity. Analytical expressions for thermal effects of water transport are given. We show how reversible heat transport (Dufour effects) can be understood in terms of coupling coefficients (heats of transfers). The sign of the enthalpy of adsorption of water in the membrane determines the sign of the coupling coefficient, the Dufour and Soret effect as well as thermal osmosis effects meaning that the effect can be large at interfaces. Weshow how data presented in the literature can be understood in terms of the presented theory. Using common estimates for transport properties in the membrane and its surface, we ?nd that the more detailed equations predict a 10 30% variation in the heat and mass fluxes as the membrane thickness drops below 1 mm. Analysis of experiments on thermal osmosis suggests that more accurate measurements on the water content as a function of activity are required.

Title: A Secure Authentication Protocol among Mobile Phone and Wireless Sensor Networks
Authors: Ndibanje Bruce, Hoon Jae Lee
Abstract: The interaction between mobile phone and wireless sensor networks has increased these days due to the WSN emergence and its ubiquitous nature. Through cellular network, a user can access gateway of wireless sensor networks and gets the data. This paper proposes a secure authentication protocol where a user is strongly verified before accessing the data. The secure authentication proposed protocol provides many security principles to the users for instance user, mutual authentication, and secure session key establishment. Furthermore, security analysis shows .that the proposed protocol possesses many advantages against popular attacks, and achieves better efficiency at low computation cost.

Title: Accelerating E-Commerce Sites in the Cloud
Authors: Wei Hao, James Walden, Chris Trenkamp
Abstract: E-commerce web sites typically have large fluctuations in their IT resource usage, while rapid elasticity is an essential characteristic of cloud computing. These characteristics make the cloud a good fit for hosting e-commerce web sites. Cloud providers deploy their cloud in their data centers. However, cloud providers usually have a limited number of data center locations around the world. Thus, e-commerce web sites in the cloud may be far away from their customers. Long client-perceived response latency may cause e-commerce web sites to lose business. To solve this problem, we propose a virtual proxy solution to reduce the response latency of the e-commerce site in the cloud. In our approach, a virtual proxy platform is designed to cache applications and data of e-commerce sites. A k-means based table partitioning algorithm is designed to select frequently used data from the database in the cloud. We have used an industrial e-commerce benchmark TPC-W to evaluate the performance of our approach. The experimental results show that our approach can significantly reduce the client-perceived response time.
