Leading education company Manhattan Prep has made it through the penultimate stage of judging to be shortlisted for the Reimagine Education Awards 2016 Digital Content Award. In response to the evolving needs of higher education, the Reimagine Education Conference & Awards has recognized Interact™, Manhattan Prep’s interactive, proprietary e-learning platform that uses intuitive technology to guide the student on a customized study path tailored to their learning needs. The Reimagine Education Conference & Awards 2016, organized by career and education network QS in collaboration with the esteemed Wharton School of the University of Pennsylvania’s SEI Center for Advanced Studies in Management, will take place in Philadelphia from December 5-6 at the Inn at Penn, a Hilton Hotel. The concept behind the Awards is that traditional education is both insufficient and overly expensive for the needs of modern students, and therefore must be “reimagined.” An international panel of 40 distinguished judges has been selected to honor “innovative education pedagogies enhancing learning and employability.” By shortlisting Interact™, the panel has deemed the product to be one of the 120 most innovative educational projects among over 500 submissions. Created to immerse students in an engaging, on-demand, self-paced learning experience, Interact™ offers full GMAT and LSAT prep courses in which students can determine their own paths to success. Guided entirely by 99th percentile Manhattan Prep instructors, the program aims to connect students to comprehensive, interactive instruction that will benefit them before, during, and after the test. “It’s our deep belief at Manhattan Prep that exceptional teachers are the centerpiece of a transformational learning experience, but featuring teachers in self-study products is a challenge.” said Noah Teitelbaum, the company’s VP of Instruction & Customer Experience. “Interact™ is our answer to the challenge of creating a self-study product that harnesses the power of great teaching. Being shortlisted for this award is proof that what we’re doing is stretching ed tech’s boundaries.” Rey Fernández, the company’s VP & General Manager, added that “the product is authentic in aiming to create a student-teacher connection in a usually sterile and staid delivery mode. What makes Interact™ great is what makes our classrooms great too.” If Interact™ is selected as the 2016 Digital Content Award winner, it will have been deemed “the project that...creates the most compelling, detailed, informative digital content, with an interface or medium designed to support learners everywhere.”

Transport in Porous Media | Year: 2011
In this article, we derive a simple expression for the tortuosity of porous media as a function of porosity and of a single parameter characterizing the shape of the porous medium components. Following its value, a very large range of porous materials is described, from non-tortuous to high tortuosity ones with percolation limits. The proposed relation is compared with a widely used expression derived from percolation theory, and its predictive power is demonstrated through comparison with numerical simulations of diffusion phenomena. Application to the tortuosity of hydrated polymeric membranes is shown. © 2011 Springer Science+Business Media B.V.

The analysis of the solar power collected at the receiver in solar tower systems requires the use of efficient and accurate numerical codes. This paper presents a new Fortran computer program, CRS4-2 (an acronym for Crs4 Research Software for Central Receiver Solar System SimulationS), for the simulation of the optical performance of a central receiver solar plant. The implemented mathematical algorithm allows for the calculation of cosine, shading and blocking effects for heliostats arbitrarily arranged in the solar field. Special attention has been given to ensure the maximum flexibility concerning the number, dimension, shape, and position of the heliostats. In the present implementation, the solar field can be composed of both square and circular heliostats possibly mixed together, each one of them characterized by the size and height from the ground. The modular design of CRS4-2 allows the extension to heliostats of arbitrary shape with only minor modifications of the code. Shading and blocking effects are computed by a tessellation of the heliostats: therefore, the numerical accuracy depends only on the refinement of the tessellation. The application to actual systems has shown that the approach is stable and general. © 2011 Elsevier Ltd.

Background: Reverse-engineering gene networks from expression profiles is a difficult problem for which a multitude of techniques have been developed over the last decade. The yearly organized DREAM challenges allow for a fair evaluation and unbiased comparison of these methods. Results: We propose an inference algorithm that combines confidence matrices, computed as the standard scores from single-gene knockout data, with the down-ranking of feed-forward edges. Substantial improvements on the predictions can be obtained after the execution of this second step. Conclusions: Our algorithm was awarded the best overall performance at the DREAM4 In Silico 100-gene network sub-challenge, proving to be effective in inferring medium-size gene regulatory networks. This success demonstrates once again the decisive importance of gene expression data obtained after systematic gene perturbations and highlights the usefulness of graph analysis to increase the reliability of inference. © 2010 Pinna et al.

Transport in Porous Media | Year: 2016
In this article, the dependence of tortuosity on the geometrical structure of a porous medium is studied. In particular, the considered porous media have anisotropic structures, being composed by a collection of object of similar shape, with a well-defined orientation. Geometrical expressions for the tortuosity as a function of the porosity, of shape factors characterizing the geometry of the solid objects and of the orientation of the flow with respect to the object axes are derived. Besides the general case, two simpler expressions are derived for 2D porous media and for media composed by axisymmetric objects. The expressions for the two particular cases are validated through a series of numerical simulations of diffusion phenomena, finding a good agreement. The model is also compared with experimental data from literature, showing its possible use in the prediction of the transport properties of a porous medium made by assembling similar solid particles, by a simple geometrical characterization of its components. Finally, a parametric analysis is performed, showing a strong dependence of the tortuosity on the objects shape and on their orientation with respect to the flow. The capability of the presented model to predict such effects can be used to design materials with particular non-isotropic transport characteristics. © 2016 Springer Science+Business Media Dordrecht

WWW'12 - Proceedings of the 21st Annual Conference on World Wide Web Companion | Year: 2012
The Web of Things is a scenario where potentially billions of connected smart objects communicate using the Web protocols, HTTP in primis. A Web of Things envisioning and design has raised several research issues, from protocols adoption and communication models to architectural styles and social aspects facing. In this demo we present the prototype of a scalable architecture for a large scale social Web of Things for smart objects and services, named Paraimpu. It is a Web-based platform which allows to add, use, share and inter-connect real HTTP-enabled smart objects and "virtual" things like services on the Web and social networks. Paraimpu defines and uses few strong abstractions, in order to allow mash-ups of heterogeneous things introducing powerful rules for data adaptation. Adding and inter-connecting objects is supported through user friendly models and features. Copyright is held by the International World Wide Web Conference Committee (IW3C2).

Solar Energy | Year: 2012
The design of a beam-down solar power plant represents a very complex problem, being its performance dependent on many interrelated parameters. A systematic analysis of these parameters is proposed in the present study. The effect of the hyperboloid eccentricity on both the sunshape and the size of the heliostats is analyzed. Optimal values of the characteristic parameters of the compound parabolic concentrator are also proposed and on the basis of these considerations, extensive calculations are presented to evaluate yearly solar power collection. © 2011 Elsevier Ltd.
