On the effect of endpoints on dynamic time warping
(Association for Computing Machinery - ACMSan Francisco, 2016-08)
While there exist a plethora of classification algorithms for most data types, there is an increasing acceptance that the unique properties of time series mean that the combination of nearest neighbor classifiers and Dynamic ...
Multi-layer perceptrons to reduce ground reflection effect in real-time locating systems
(01/26/2012)
Nowadays, indoor Real-Time Locating Systems represent one of the most exciting applications based on Wireless Sensor Networks using wireless technologies such as Wi-Fi or ZigBee. Indoor Real-Time Locating Systems based on ...
Assessment of the hypnotic/sedative effects and toxicity of Passiflora edulis aqueous extract in rodents and humans
(Wiley-Blackwell, 1991-12-01)
Passiflora species are used in folk medicine as hypnotic and sedative treatments. in this study the hypnotic-sedative effects and toxicity of Passiflora edulis were assessed in rats and mice and in healthy volunteers. It ...
Discrete-time sliding mode control of input-delay systems applied on a power generation system
(2006-12-01)
This paper presents two discrete sliding mode control (SMC) design. The first one is a discrete-time SMC design that doesn't take into account the time-delay. The second one is a discrete-time SMC design, which takes in ...
On the possibility of experimental observation of diffraction in the time effects
(Revista Mexicana de Física, 2009)
Sliding mode for detection and accommodation of computation time delay fault
(Elsevier B.V., 2009-10-01)
Computation time delay in digital control systems reduces its robustness as well as degrades its performance. In this paper, the computation time delay is assumed to be constant and smaller than the sampling time and is ...
Mitigation of the ground reflection effect in real-time locating systems based on wireless sensor networks by using artificial neural networks
(01/01/2013)
Wireless sensor networks (WSNs) have become much more relevant in recent years, mainly because they can be used in a wide diversity of applications. Real-time locating systems (RTLSs) are one of the most promising applications ...
Space-time waves from a collapse with a time dependent cosmological parameter
(Springer, 2020-02)
We study the emission of space-time waves produced by back-reaction effects during a collapse of a spherically symmetric universe with a time-dependent cosmological parameter, which is driven by a scalar field. As in a ...
Importance of Effective Instructional Time in Academic Achievement: Results of a Mixed Approach in Colombia
Instrumental variables were implemented to estimate the consequences of effective instructional time on the performance of Colombian students in the Saber 11 examination. When increasing in a standard deviation, the effective ...
