Due to the climate change debate, a lot of research and maps of external climate parameters are available. However, maps of indoor climate performance parameters are still lacking. This paper presents a methodology for obtaining maps of performances of similar buildings that are virtually spread over whole Europe. The produced maps are useful for analyzing regional climate influence on building...

We propose an efficient parallel bundle adjustment (BA) algorithm to refine 3D reconstruction of the large-scale structure from motion (SfM) problem, which uses image collections from Internet. Different from the latest BA techniques that improve efficiency by optimizing the reprojection error function with Conjugate Gradient (CG) methods, we employ the parameter vector partition strategy. More...

In this paper, we will describe an idea and its implementation for an ngram search engine for very large sets of ngrams. The engine supports queries with an arbitrary number of wildcards. It takes a fraction of a second for a search, and can provide the fillers of the wildcards. We implemented the system using two datasets. One is the 1 billion 5-grams provided by Google (Web 1T data), the othe...

This paper describes the implementation of error detection and correction logic in the optoelectronic cache memory prototype at the University of Pittsburgh. In this project, our goal is to integrate a 3D optical memory directly into the memory hierarchy of a personal computer. As with any optical storage system, error correction is essential to maintaining acceptable system performance. We hav...

of the Thesis An Area Efficient 4Gb/s 3-Tap Decision Feedback Equalizer with Current-Integrating Summer by Chen Zhang Master of Science in Electrical and Computer Engineering Northeastern University, April 2016 Prof. Yong-Bin Kim, Adviser As the requirement of wire line applications increases, the demand for higher data transmission bandwidth is continuously exploding. While the on-chip speed h...

The DS40MB200 is a dual 2:1 multiplexer and 1:2 fan-out repeater designed to support redundancy and extending copper backplane to data rates up to 4 Gb/s. With input equalization and output pre-emphasis, the DS40MB200 is capable of compensating attenuation distortion and reducing deterministic jitter caused by bandwidth-limited transmission lines. This application note outlines the methods to s...

Low voltage power distribution system problems such as planning, energy loss minimization and restoration usually involve proper load balancing or network reconfiguration procedures. To achieve an appreciable level of phase balance, feeder using appropriate switching control strategy as: Simulated Annealing, Tabu Search, Particle Swarm Optimization, heuristic algorithms are viable preferences. ...

The popularity of the cloud storage systems has brought a number of challenges. Two of them are data integrity and energy efficiency. There are many proposed static solutions to prove the integrity of a file. For the dynamic case, Rank-Based Authenticated Skip list (RBASL) has been presented. It provides the update operations with logarithmic complexity. However, an RBASL expects the block size...
