A Prototype Toolkit For Evaluating Indoor Environmental Quality In Commercial Buildings
Measurement of building environmental parameters is often complex, expensive, and not easily proceduralized in a manner that covers all commercial buildings. Evaluating building indoor environmental quality performance is therefore not standard practice. This project developed a prototype toolkit that addressed existing barriers to widespread indoor environmental quality performance evaluation. A toolkit with both hardware and software elements was designed for practitioners around the indoor environmental quality requirements of the American Society of Heating, Refrigeration and Air Conditioning Engineers / Chartered Institution of Building Services / United States Green Building Council Performance Measurement Protocols. This unique toolkit was built on a wireless mesh network with a web-based data collection, analysis, and reporting application. The toolkit provided a fast, robust deployment of sensors, real-time data analysis, Performance Measurement Protocol-based analysis methods and a scorecard and report generation tools. A web-enabled Geographic Information System-based metadata collection system also reduced field-study deployment time. The toolkit was evaluated through three case studies, which were discussed in this report
Mixed Variational Formulation for the Wellposedness and Numerical Approximation of a PDE Model Arising in a 3-D Fluid-Structure Interaction
We present qualitative and numerical results on a partial differential equation (PDE) system which models a certain fluid-structure dynamics. Wellposedness is established by constructing for it a nonstandard semigroup generator representation; this representation is accomplished by an appropriate elimination of the pressure. This coupled PDE model involves the Stokes system which evolves on a three dimensional domain O coupled to a fourth order plate equation, possibly with rotational inertia parameter ρ\u3e0. This plate PDE evolves on a flat portion Ω of the boundary of O. The coupling on Ω is implemented via the Dirichlet trace of the Stokes system fluid variable - and so the no-slip condition is necessarily not in play - and via the Dirichlet boundary trace of the pressure, which essentially acts as a forcing term on Ω. We note that as the Stokes fluid velocity does not vanish on Ω, the pressure variable cannot be eliminated by the classic Leray projector; instead, it is identified as the solution of an elliptic boundary value problem. Eventually, wellposedness of the system is attained through a nonstandard variational (``inf-sup ) formulation. Subsequently we show how our constructive proof of wellposedness naturally gives rise to a mixed finite element method for numerically approximating solutions of this fluid-structure dynamics

A 2D Parallel Triangle Counting Algorithm for Distributed-Memory Architectures
Triangle counting is a fundamental graph analytic operation that is used
extensively in network science and graph mining. As the size of the graphs that
needs to be analyzed continues to grow, there is a requirement in developing
scalable algorithms for distributed-memory parallel systems. To this end, we
present a distributed-memory triangle counting algorithm, which uses a 2D
cyclic decomposition to balance the computations and reduce the communication
overheads. The algorithm structures its communication and computational steps
such that it reduces its memory overhead and includes key optimizations that
leverage the sparsity of the graph and the way the computations are structured.
Experiments on synthetic and real-world graphs show that our algorithm obtains
an average relative speedup that range between 3.24 and 7.22 out of 10.56
across the datasets using 169 MPI ranks over the performance achieved by 16 MPI
ranks. Moreover, we obtain an average speedup of 10.2 times on comparison with
previously developed distributed-memory parallel algorithms.Comment: 10 pages, 3 figures, 48th International Conference on Parallel

What Is Important In Reading In Middle Level Classrooms: A Survey of Classroom Teachers\u27 Perceptions
Should reading instruction in middle level schools be aimed at helping youngsters to acquire more specific, isolated skills of how to read? Or should the focus of reading in middle level schools be on assisting learners to become readers? An answer to both of these critical questions might be — yes. Middle level learners (10 to 14 years old) should grow both in their skillfulness as readers and in the process of becoming readers. Research data and current instructional practices can be found to support both of these positions
