Some Topological Aspects of Sampling Theorem and Reconstruction Formula [PDF]
International Journal of Electronics and Telecommunications, 2020 We present here a few thoughts regarding topological aspects of transferring a signal of a continuous time into its discrete counterpart and recovering an analog signal from its discrete-time equivalent.

Efficient Path Planing for Articulated Vehicles in Cluttered Environments
Sensors, 2020 Motion planning and control for articulated logistic vehicles such as tugger trains is a challenging problem in service robotics. The case of tugger trains presents particular difficulties due to the kinematic complexity of these multiarticulated ...

Empirical Casestudy on Approaches to Sampled Control
Mendel, 2017 Two main approaches on sampled control are compared, the descrete equivalent design and the direct discrete design. Both design methods are used to implement a control system for a real plant, DC-motor.

Multirate cascaded discrete-time low-pass ΔΣ modulator for GSM/Bluetooth/UMTS [PDF]
, 2010 This paper shows that multirate processing in a cascaded discrete-time ΔΣ modulator allows to reduce the power consumption by up to 35%. Multirate processing is possible in a discrete-time ΔΣ modulator by its adaptibility with the sampling frequency. The

On the Calculation of Sample Entropy Using Continuous and Discrete Human Gait Data
Entropy, 2018 Sample entropy (SE) has relative consistency using biologically-derived, discrete data >500 data points. For certain populations, collecting this quantity is not feasible and continuous data has been used.

Discrete water quality sampling at open-water aquaculture sites: limitations and strategies
Aquaculture Environment Interactions, 2016 While environmental performance of cage-based aquaculture is most often monitored through benthic conditions, there may also be requirements that necessitate discrete, pelagic sampling.
