Brain-computer interfaces (BCI) based on Steady State Visual Evoked Potential (SSVEP) can provide higher information transfer rate than other BCI modalities. For the sake of safety and comfort, the frequency of the repetitive visual stimulus (RVS) necessary to elicit an SSVEP, should be higher than 30 Hz. However, in the frequency range above 30 Hz, only a limited number of frequencies can elic...

The research aims to identify the impact of an educational curriculum inverted vertical learning transfer for front and back straight kick skills in table tennis, reveal preference two groups. third is Department Physical Education College Basic at Karmian University, their average age was (24-22) years, they were regular school year (2021-2022) AD, tested kicks as sample divided into equal gro...

A study on the dynamic behaviour of a rotary table transfer machine is discussed in this paper. Part modelling is performed through the application of finite element techniques. Experimental modal analysis is exploited for substructure updating. The assembled model is obtained using constraint equations and boundary conditions. Design modifications are proposed to enhance the dynamic behaviour ...

IEEE 802.11 MAC protocol has been the standard for Wireless LANs, and also adopted in many network simulation packages for wireless multi-hop ad hoc networks. However, it is well known that, as the traffic goes up, the performance of IEEE 802.11 MAC drops dramatically in terms of delay and throughput, especially when the station approaches its saturation state. To explore the inherent problems ...

Abstract: point of view. In this study, a shaking-table was used for concentrating a manganese ore sample from the Ghasem Abadarea in Kerman, Iran. Experiments were designed by using LThe influence of each variable and their interactions on the operation of the device was studied. The variables underinvestigation were: table slope, table frequency, water flowrate, feed rate, and particle size. ...

Data warehouse related technologies, allows to extract, group and analyze historical data in order to identify information valuable to decision making processes. In this paper the implementation of a weather data warehouse (WDW) to store Mexico’s weather variables is presented. The weather variables data were provided by the Mexican Institute for Water Technologies (IMTA), the IMTA does researc...
