The concept of sustainable development (SD) has become widely accepted among nations, organisations, and individuals. Recent quantitative conceptual models have indicated relations between stakeholder perspectives SD, brand image, customer satisfaction. purpose this study is to estimate a Sustainable Development Index (SDI) as an easy applicable survey item which used perceptions. By applying P...
BACKGROUND Many patients with electrical dyssynchrony who undergo cardiac resynchronization therapy (CRT) do not obtain substantial benefit. Assessing mechanical dyssynchrony may improve patient selection. Results from studies using echocardiographic imaging to measure dyssynchrony have ultimately proved disappointing. We sought to evaluate cardiac motion in patients with heart failure and elec...
Therapy (MUSIC study). Abstract Aims: Strain delay index (SDI) allows quantification of the wasted contraction or gain of myocardial contractility expected after cardiac resynchronization therapy (CRT). The present multicenter prospective study aimed to assess the accuracy of the SDI in predicting responses to CRT in real life patients that include wide and narrow (<130ms) QRS complexes. Method...
We analyzed the relationship between Landsat ETM+ reflectance values and commercially managed loblolly pine (Pinus taeda L.) stand characteristics in east Texas. Multivariate regression techniques were used to predict age and tree density for all stands. A linear combination of NDVI, ETM4/ETM3 and the tasseled cap wetness index was a better predictor of stand age (R = 78%) than other combinatio...
AIMS Strain delay index (SDI) allows quantification of the wasted contraction or gain of myocardial contractility expected after cardiac resynchronization therapy (CRT). The present multicentre prospective study aimed to assess the accuracy of the SDI in predicting responses to CRT in real-life patients with wide and narrow (<130 ms) QRS complexes. METHODS AND RESULTS Implantation of a CRT de...
In a selective information dissemination (SDI) system, users submit profiles consisting of a number of long-standing queries to represent their information needs. The system then continuously collects new documents from underlying information sources, filters them against the user profiles, and delivers relevant information to corresponding users. SDI systems are very important nowadays due to ...
Similarity search is a powerful paradigm for image and multimedia databases, time series databases, and DNA and protein sequence databases. Objects are represented by high-dimensional feature vectors based on color, texture, and shape, in the case of images, for example object similarity is usually implemented via k-nearest neighbor (k-NN) queries, determined by the distance of the endpoints of...
