  Title Measuring the Reduction of the Confinement along the Evolution of a Burn Cut Type
  Year 2019 Publication Applied Sciences-Basel Abbreviated Journal Appl. Sci.-Basel  
  Volume 9 Issue 23 Pages 17 pp  
  Keywords blasting; vibrations; burn cut  
  Abstract We provide an analysis of a tunnel opening cut in a tunnel face. In particular, we focus on the effect of a “burn cut,” which is a typical parallel hole cut. As the evolution of the opening consists of an increase in the volume of the cut prism and the consequent reduction of confinement of the holes along the initiation sequence, we analyze such an evolution using photographic documentation, as well as evaluating the reduction of confinement by measuring the energy transferred from the explosive charge to the rock mass. The energy was estimated by monitoring and analyzing the vibrations induced by the blasting at three different points. We adopted low-cost shock sensors for monitoring the effect of the detonation times at short distance from the blast (about 10 m). The results show an evident reduction of the shock transfer to the rock mass (i.e., a reduction of confinement) with the increase of the cavity opening. Nevertheless, when only the response of the piezometric sensors was considered, a disparity in behavior among the sensors was noted. On the other hand, when the sensor response was integrated over time, the behavior of all sensors normalized, showing the need to focus both on the oscillation and the duration to properly address the shock effect.

  Title Novel Reversible Comparator Design in Quantum Dot-Cellular Automata with Power Dissipation Analysis Type
  Year 2022 Publication Applied Sciences-Basel Abbreviated Journal Appl. Sci.-Basel  
  Volume 12 Issue 15 Pages 7846  
  Keywords QCA; reversible logic; comparator; Feynman gate; TR gate; coplanar; quantum cost; energy dissipation  
  Abstract In very large-scale integration (VLSI) circuits, a partial of energy lost leads to information loss in irreversible computing because, in conventional combinatorial circuits, each bit of information generates heat and power consumption, thus resulting in energy dissipation. When information is lost in conventional circuits, it will not be recoverable, as a result, the circuits are provided based on the reversible logic and according to reversible gates for data retrieval. Since comparators are one of the basic building blocks in digital logic design, in which they compare two numbers, the aim of this research is to design a 1-bit comparator building block based on reversible logic and implement it in the QCA with the minimum cell consumption, less occupied area, and lower latency, as well as to design it in a single layer. The proposed 1-bit reversible comparator is denser, cost-effective, and more efficient in quantum cost, power dissipation, and the main QCA parameters than that of previous works.

  Title An Outdoor Navigation System for Blind Pedestrians Using GPS and Tactile-Foot Feedback Type
  Year 2018 Publication Applied Sciences-Basel Abbreviated Journal Appl. Sci.-Basel  
  Volume 8 Issue 4 Pages 15 pp  
  Keywords assistive technology; blind pedestrian; GPS localization; mobile computing; navigational system; tactile display; tactile-foot stimulation; wearable system  
  Abstract This paper presents a novel, wearable navigation system for visually impaired and blind pedestrians that combines a global positioning system (GPS) for user outdoor localization and tactile-foot stimulation for information presentation. Real-time GPS data provided by a smartphone are processed by dedicated navigation software to determine the directions to a destination. Navigational directions are then encoded as vibrations and conveyed to the user via a tactile display that inserts into the shoe. The experimental results showed that users were capable of recognizing with high accuracy the tactile feedback provided to their feet. The preliminary tests conducted in outdoor locations involved two blind users who were guided along 380-420 m predetermined pathways, while sharing the space with other pedestrians and facing typical urban obstacles. The subjects successfully reached the target destinations. The results suggest that the proposed system enhances independent, safe navigation of blind pedestrians and show the potential of tactile-foot stimulation in assistive devices.
