In a multi-packet reception (MPR) system, a wireless node can successfully receive multiple packets from simultaneous transmitters. The increase in the number of simultaneous transmissions leads to higher throughput as long as the transmissions can be successfully decoded by the receiver. The maximum number of simultaneous transmissions that the receiver can successfully decode should be determ...

This study aimed to explore non-verbal executive processes in simultaneous interpreters. Simultaneous interpreters, bilinguals without any training in simultaneous interpreting, and control monolinguals performed the Wisconsin card sorting task (WCST; Experiment 1) and the Simon task (Experiment 2). Performance on WCST was thought to index cognitive flexibility while Simon task performance was ...

In this paper, we deduce general observability condition of all types of SLAM solutions regardless what states they consider directly in estimation, i.e. whether SLAM is feature based or pose (graph) based. This result comes from doing nonlinear observability analysis of the pose-based SLAM. We consider general vehicle motion model whose control inputs are translational and rotational velocity ...

This work presents an artificial intelligence approach to solve the problem of finding a path and creating a map in unknown environments using Reinforcement Learning (RL) and Simultaneous Localization and Mapping (SLAM) for a differential mobile robot along with an optimal control system. We propose the integration of these approaches (two of the most widely used ones) for the implementation of...

In this paper, we introduce a novel medium access control (MAC) protocol for Radio Frequency Identification (RFID) systems. This protocol exploits the Markov Chain Model of Slotted Aloha and there by tries to come up with a more efficient model so as to significantly improve the total read time performance along with the lesser tag collision. The protocol design has been extended so as to addre...

In this paper we present a run-time mechanism to simultaneously execute multiple threads from a sequential program on a simultaneous multithreaded (SMT) processor. The threads are speculative in the sense that they are created by predicting the future control flow of the program. Moreover, threads are not necessarily independent. Data dependences among simultaneously executed threads may exist....

Processors execute the full dynamic instruction stream to arrive at the final output of a program, yet there exist shorter instruction streams that produce the same overall effect. We propose creating a shorter but otherwise equivalent version of the original program by removing ineffectual computation and computation related to highly-predictable control flow. The shortened program is run in p...

We present a visual servoing approach for controlling a micro aerial vehicle which is based on monocular camera input and a fuzzy logic controller. Visual pose estimates are obtained using a state-of-theart visual SLAM approach combined with marker-based metrical initialization. In comparison to related work, we demonstrate that our system tolerates quickly changing velocity measurements which ...
