14th Brazilian Symposium on GeoInformatics, GEOINFO 2013

作者： Costa, George Henrique Rangel Baldo, Fabiano Graduate Program in Applied Computing Computer Science Department UDESC Santa Catarina State University Joinville Brazil

Digital road maps have gained fundamental role in population's daily life, so they need to be accurate and up-to-date. A viable solution is to generate maps by processing GPS data. However, one of the most challenging tasks regarding this approach is how to extract road centerlines from the cloud of georeferenced GPS points. The literature presents various methods that do it, but none have been found that is prepared for the continuous update of the map and refinement of its roads' accuracy. In this context, the objective of this work is to propose a method to identify road centerlines using an evolutive algorithm in order to generate and update road maps. This work uses as source of data GPS traces collected by smartphones. Although suitable to obtain a large amount of georeferenced data, these devices bring the additional problem of identifying the transport vehicle used along each trace. Preliminary results indicate that the method's performance is satisfactory, with an average variation of 2.95 meters in relation to satellite images.

Nanostructure investigations of nonlinear differential conductance in NdNiO3 thin films

Physical Review B 2014年第20期90卷 205117-205117页

作者： Will J. Hardy Heng Ji Evgeny Mikheev Susanne Stemmer Douglas Natelson Applied Physics Program Rice Quantum Institute Rice University Houston Texas 77005 USA Department of Physics and Astronomy Rice University Houston Texas 77005 USA Materials Department University of California Santa Barbara California USA Department of Electrical and Computer Engineering and Department of Materials Science and Nanoengineering Rice University Houston Texas 77005 USA

Transport measurements on thin films of NdNiO3 reveal a crossover to a regime of pronounced nonlinear conduction below the well-known metal-insulator transition temperature. The evolution of the transport properties at temperatures well below this transition appears consistent with a gradual formation of a gap in the holelike Fermi surface of this strongly correlated system. As T is decreased below the nominal transition temperature, transport becomes increasingly non-Ohmic, with a model of Landau-Zener breakdown becoming most suited for describing I(V) characteristics as the temperature approaches 2 K.

Banana peel and biodiesel derived glycerol are one of the most abundant agricultural waste in Southeast Asian countries. This current research demonstrated potential biomethane production from co-digestion of agricultural wastes under mesophilic fermentation. The wastes used include (1) banana peel (varying total solids in the range 2.5-10% w/v) and (2) Banana peel mixed with pure or waste glycerol. All treatments were setup in duplicate in 0.5 L batch reacotr. Gas and liquid samples were collected every 12 and 24 hr, respectively. Maximum methane production potential and yield were 181 mL and 188 mL g -1 TS at 7.5% banana peel. The maximum methane production potential and yield of 7.5% banana peel mixed with 7.5 g L -1 pure glycerol (in the presence of buffer) were 467 mL and 151 mL g -1 COD, respectively, while those of 7.5% banana peel mixed with 7.5 g L -1 waste glycerol (in the presence of buffer) were 652 mL and 281 mL g -1 COD, respectively. Small amount of VFAs and ethanol was accumulated in the reactor content. The current findings indicate the potential use of glycerol waste as a co-substrate in biomethane production.

Biological hydrogen production from glycerol waste with glucose as co-substrate was tested in batch reactor at the varying mass ratios of glycerol and glucose. All ratios have equivalent extent of total chemical oxygen demand of 9.13 g L -1 .COD. Fermentation was setup in 0.5 L glass bottle, 37 o C, and pH 6. Liquid and gas samples were collected to analyze concentrations of volatile fatty acids and glycerol; and gas compositions. The results showed that glycerol/glucose ratio plays an important role on the H 2 yield. Maximum H 2 yield was obtained at the glycerol/glucose ratio of 75:1. Acetate and butyrate were the main fermentative end products. This work demonstrated glucose can be used as a co-substrate to promote the H 2 yield in the fermentation of waste glycerol.

This paper reports an effective method of packaging a fiber Bragg grating (FBG) for the simultaneous measurement of temperature and strain. The technique consists of embedding two fiber Bragg grating sensors inside a polymeric material with different geometrical characteristics. The mechanical and thermal characterizations of the optical transducer were performed. Then a matrix equation used measurements of the wavelength shifts from the two sensors and yielded information about the temperature and strain coefficients. The preliminary results demonstrate the feasibility of the encapsulation technique allowing measurements of temperature and strain in smart structures and harsh environments. The experimental procedure provides robustness to the sensor and the matrix equation approach has the potential to determine simultaneously the strain and temperature coefficients. © 2013 SBMO/SBMag.

Inter-organizational Global Software Development (GSD) has become a common reality for many projects. It is well established that distance makes difficult to interact and to cooperate effectively. Scrum, a consolidated Agile methodology, emphasizes communication, reduces coordination and control overhead and has been increasingly used in a distributed fashion. Successfully planning and managing the combined use of GSD and Scrum is a complex task and requires carefully planning. Despite the importance and complexity of this type of problem, there seems to be a lack of reports, in the literature, of models that could support managers dealing with these decision contexts. This paper presents a multi-criteria decision model for planning and fine-tuning such project plans. This model was developed using cognitive mapping and MACBETH [1]. The application of the model is demonstrated, followed by conclusion and future work. © Springer-Verlag Berlin Heidelberg 2013.

We demonstrate fast universal electrical spin manipulation with inhomogeneous magnetic fields. With fast Rabi frequency up to 127 MHz, we leave the conventional regime of strong nuclear-spin influence and observe a spin-flip fidelity >96%, a distinct chevron Rabi pattern in the spectral-time domain, and a spin resonance linewidth limited by the Rabi frequency, not by the dephasing rate. In addition, we establish fast z rotations up to 54 MHz by directly controlling the spin phase. Our findings will significantly facilitate tomography and error correction with electron spins in quantum dots.
