In this paper, we propose a new approach for offline signature verification based on score level fusion of distance and orientation features of centroids. The proposed method employs symbolic representation of offline signatures using bi-interval valued feature vector. Distance and orientation features of centroids of offline signatures are used to form bi-interval valued symbolic feature vecto...

Multi-thread polling (MTP) with offline scheduling and offline excess bandwidth distribution has recently been proposed to overcome the long propagation delay of long-reach passive optical networks (LR-PONs). In this paper, we propose a complementary MTP approach with online scheduling and online excess bandwidth distribution. We evaluate the throughput-delay performance of offline and online M...

Im Zuge der notwendigen Integration weiterer Geodaten in die forstfachlichen Geschäftsprozesse hat sich der Landesbetrieb Wald und Holz NRW Ende 2012 dazu entschlossen, einen gleichfalls innovativen und zukunftssicheren Weg einzuschlagen. Basierend auf einem aktuellen JavaScript und HTML5 Framework zum Aufbau moderner Web-GIS Anwendungen (map.apps der con terra GmbH), erfolgte die Umsetzung ein...

The notion of online/offline encryption was put forth by Guo, Mu and Chen (FC 2008), where they proposed an identity-based scheme called identity-based online/offline encryption (IBOOE). An online/ offline encryption separates an encryption into two stages: offline and online. The offline phase carries much more computational load than the online phase, where the offline phase does not require ...

This work derives a residual-based posteriori error estimator for reduced models learned with non-intrusive model reduction from data of high-dimensional systems governed by linear parabolic partial differential equations control inputs. It is shown that quantities are necessary the can be either obtained exactly as solutions least-squares problems in way such initial conditions, inputs, and so...

As permanent magnet synchronous motors (PMSM) have high power density, efficiency, good dynamic performance, and small size they are becoming popular in electric vehicle (EV) applications. Control performance the efficiency of system get affected due to electrical, mechanical parameters. Parameters value gets by voltage source inverter (VSI) non-linearities, temperature magnetic saturation effe...

This paper addresses the robust output feedback model predictive control (MPC) schemes for networked systems (NCSs) with input quantization. The logarithmic quantizer is considered in this paper, and sector bound approach applied, which appropriately treats quantization error as a sector-bounded uncertainty. presented method involves an offline designed state observer using linear matrix inequa...

BACKGROUND Online hearing tests conducted in home settings on a personal computer (PC) require prior calibration. Biological calibration consists of approximating the reference sound level via the hearing threshold of a person with normal hearing. OBJECTIVE The objective of this study was to identify the error of the proposed methods of biological calibration, their duration, and the subjecti...
