abstracttask-based language teaching is considered an effective way to achieve a harmony between grammar and communication. the present study investigates two different ways of teaching modal verbs: task-based versus traditional approaches. to this purpose, an oxford placement test was administered to select 40 homogeneous participants out of a larger population who took this test. the selected...

wireless sensor networks(wsn) have unique properties that distinguished them from other wireless networks and have special challenges. not-chargeable, not-changeable and limited power supplies of sensor nodes is the most important challenge of this networks, and if the power supply of node expired, a part of data maybe lost. because of the importance of covers in wireless sensors, in this work ...

We employ so-called quantum kernel estimation to exploit complex dynamics of solid-state nuclear magnetic resonance for machine learning. propose map an input a feature space by input-dependent Hamiltonian evolution, and the is estimated interference evolution. Simple learning tasks, namely one-dimensional regression tasks two-dimensional classification are performed using proton spins which ex...

The distribution of workflow-like dependent tasks over a set of heterogeneous resources is an NP-Complete problem. Thus, many solutions are heuristic-based, leading to simulations for the validation and comparison of dependent task scheduling algorithms. However, simulations concerning the algorithms’ performance when executed in non-dedicated resources with a wide range of bandwidth capacities...
