Emerging Physical Unclonable Functions With Nanotechnology

March 17, 2017


Physical unclonable functions (PUFs) are increasingly used for authentication and identification applications as well as the cryptographic key generation. An important feature of a PUF is the reliance on minute random variations in the fabricated hardware to derive a trusted random key. Currently, most PUF designs focus on exploiting process variations intrinsic to the CMOS technology. In recent years, progress in emerging nanoelectronic devices has demonstrated an increase in variation as a consequence of scaling down to the nanoregion. Read more

Smart Cities, Big Data, and Communities: Reasoning From the Viewpoint of Attractors

March 10, 2017


In what sense is a city smart? There are established entities defining this rich area of cross-disciplinary studies, and they refer to social, technical, economic, and political factors that keep evolving, thus offering opportunities for constant refinement of the concept of smart city. The emerging properties are mostly contextual, and affect urban data types and their capacity to form complex information systems. A well-known problem in computational analysis is the integration of lot of generated data. Read more

Case Study: NHTSA’s Denial of Dr Raghavan’s Petition to Investigate Sudden Acceleration in Toyota Vehicles Fitted With Electronic Throttles

March 3, 2017


The Raghavan petition to National Highway Traffic Safety Administration (NHTSA) concerns a sudden acceleration (SA) incident experienced by the petitioner’s wife in a 2009 Lexus ES350 automobile. As she drove slowly into a parking space, the engine roared. When she braked, there was no response and the vehicle accelerated onto to a sidewalk into some bushes, hit a fence, and then stopped. The petitioner cites two other similar SA crashes where the electronic data recorder (EDR) results showed no pedal sensor voltage signals during most of the 4-5 s before impact. Read more

Gait Balance and Acceleration of a Biped Robot Based on Q-Learning

February 17, 2017


This paper presents a method for the biped dynamic walking and balance control using reinforcement learning, which learns dynamic walking without a priori knowledge about the dynamic model. The learning architecture developed is aimed to solve complex control problems in robotic actuation control by mapping the action space from a discretized domain to a continuous one. It employs the discrete actions to construct a policy for continuous action. The architecture allows for the scaling of the dimensionality of the state space and cardinality of the action set that represents new knowledge, Read more

Design of Smart Sensors for Real-Time Water Quality Monitoring

February 10, 2017


This paper describes work that has been done on design and development of a water quality monitoring system, with the objective of notifying the user of the real-time water quality parameters. The system is able to measure the physiochemical parameters of water quality, such as flow, temperature, pH, conductivity, and the oxidation reduction potential. These physiochemical parameters are used to detect water contaminants. The sensors, which are designed from first principles and implemented with signal conditioning circuits, Read more

ERDT: Energy-efficient Reliable Decision Transmission for Intelligent Cooperative Spectrum Sensing in Industrial IoT

Correct decision probability Pe of ERDT and DT with N=10
February 3, 2017


Due to harsh environment, large number of sensors, limited energy, and spectrum scarcity, intelligent sensing becomes a key issue to enable many practical applications in industrial Internet of Things (IoT). In such an industrial environment with noise and interference, an efficient cooperative spectrum sensing (CSS) scheme can achieve spectrum sharing between primary users (PUs) and secondary users (SUs), and effectively solve the spectrum scarcity and reduce energy consumption to make the IoT smarter.

Design of Autonomous and Manual Driving System for 4WIS4WID Vehicle

January 27, 2017


In this paper, we propose a driving system consisting of an autonomous and manual system for a four-wheel independent steering and four-wheel independent driving (4WIS4WID) vehicle. The autonomous driving system consists of three applications, lane following, reverse parking, and parallel parking, and is based on machine vision and fuzzy control theory. The vehicle implements these functions by using four webcams to detect lines on the ground and by using related control technologies to command all the server motors. Read more

A Cloud-Based Smart-Parking System Based on Internet-of-Things Technologies

January 20, 2017


This paper introduces a novel algorithm that increases the efficiency of the current cloud-based smart-parking system and develops a network architecture based on the Internet-of-Things technology. This paper proposed a system that helps users automatically find a free parking space at the least cost based on new performance metrics to calculate the user parking cost by considering the distance and the total number of free places in each car park. This cost will be used to offer a solution of finding an available parking space upon a request by the user and a solution of suggesting a new car park if the current car park is full. Read more

Managing Big City Information Based on WebVRGIS

Left: Above-ground city; Right: Underground data (i.e. underground pipelines).
January 13, 2017


A 3-D Shenzhen City Web platform based on the Web virtual reality geographical information system is presented. A 3-D global browser is employed to load multiple types of demand data from the city, such as 3-D building model data, residents’ information, and real-time and historical traffic data. Using these data, a 3-D analysis and visualization of the city’s information are conducted on a platform. The amount of information that can be visualized with this platform is very large, Read more
