On finding common neighborhoods in massive graphs

2003

AbstractWe consider the problem of finding pairs of vertices that share large common neighborhoods in massive graphs. We prove lower bounds on the resources needed to solve this problem on resource-bounded models of computation. In streaming models, in which algorithms can access the input only a constant number of times and only sequentially, we show that, even with randomization, any algorithm that determines if there exists any pair of vertices with a large common neighborhood must essentially store and process the input graph off line. In sampling models, in which algorithms can only query an oracle for the common neighborhoods of specified vertex pairs, we show that any algorithm must …

Three-dimensional imaging of cardiac mass lesions by transesophageal echocardiographic computed tomography.

1994

Three-dimensional echocardiography is a new imaging technique that allows more realistic visualization of cardiac morphology. This study presents data about the diagnostic potentials of this technique concerning cardiac mass lesions, as well as its feasibility in clinical application. After the conventional investigation, multiple cross-sectional images were obtained during automatic forward advancement of a monoplane transducer mounted on a transesophageal probe. Three-dimensional reconstruction and volume determination were performed off line. Twenty-four patients were studied. In 14 cases results of echocardiographic computed tomography (echo-CT) were compared with those of monoplane/bip…

ODIn — A setup for Off-line Deposit Irradiations of thin layers for nuclear physics applications

2020

Abstract A table top setup was developed for the irradiation of thin layers with low-energy electrons and ions of gaseous species. This serves to gain a better understanding of the chemical microprocesses involved during irradiations. The gained insights will complement the understanding of heavy-ion beam induced transformations at on-line facilities and will be used to develop an accelerator-independent method to transform freshly produced targets into a long-term stable form. The pilot experiment for these Off-line Deposit Irradiations (ODIn) is installed at the Helmholtz Institute Mainz. The setup, beam characterization and first commissioning are described.

A new off-line ion source facility at IGISOL

2019

An off-line ion source station has been commissioned at the IGISOL (Ion Guide Isotope Separator On-Line) facility. It offers the infrastructure needed to produce stable ion beams from three off-line ion sources in parallel with the radioactive ion beams produced from the IGISOL target chamber. This has resulted in improved feasibility for new experiments by offering reference ions for Penning-trap mass measurements, laser spectroscopy and atom trap experiments.

Influence of Social Networks from Cellphones to Choose Restaurants, Salinas – 2016

2018

Inclusion of technology as part of business strategies has made consumers have other tools that help them to find information and making consumer decisions. It is here the importance of knowing influence of comments have in social networks in taking decisions of visits to restaurants. For this work, a qualitative method (focal group) was used in the first part and then a quantitative method was used (off line and online survey). The sample for focal group was made up by Equinoctial Technological University’s students in Santa Elena, the same ones belonged to the careers of Finance and Audit (7 students), Business and Business (1 student) and 2 graduates of the Finance and Audit. An experime…
