Published: November 2017

Abstract
A tree topology is used to construct to construct a Zigbee networks practices by wireless sensor network for data delivery applications. There are 3 types of nodes in zigbee networks; coordinator, router and mobile end devices. Coordinator performs the initialization and maintenance functions in the network. A router is responsible for routing data between the coordinator and mobile end device. In-order to avoid the delivery failures occurs due to node movements and network topology changes, the existing system collect and analyze data about device movement and gives Zigbee node deployment and tree construction framework, which uses three algorithms ZND(zigbee node deployment), ZCD(zigbee coordinator decision) and ZTC(zigbee tree construction). In the proposed system we improve the data delivery by introducing the capacity calculation. If any two nodes have same number of indegree or out-degree, we select the node with maximum capacity.

Published: November 2017

Abstract
Mobile ad hoc networks (MANETs) are collections of wireless mobile devices with restricted broadcast range and resources and no fixed infrastructure. Communication is achieved by communicating data along suitable routes that are dynamically discovered and maintained through association between the nodes. Discovery of such routes is a major task both from good organization and security points of view. Recently a security model tailored to the specific requirements of MANETs. A novel route discovery algorithm called endairA is also proposed together with a claimed security proof within the same model. In this paper we show the security proof for the route discovery algorithm endairA is malfunctioning and moreover this algorithm is vulnerable to a hidden channel attack. We also analyze the security framework that is used for route discovery and argue the compos ability is an essential feature for ubiquitous applications. We conclude by discussing some of the major security challenges for route discovery in MANETs.

Published: November 2017

Abstract
This project is concerned to analyze and increase the efficiency of patrol inspection and thus reduces time consumption for inspection. Inspection is the process of checking whether the specification of the product meet the standard specification provided by the customer. Inspector takes more time for checking the parameter that meet the specification at all time than Checking the parameters that does not satisfy the customer specification which leads to rejection .Thus the inspector should inspect the parameter that increase the rejection or rework with more attention .on the whole this concept helps the inspector to improve the quality of the product by inspecting more components according to the frequency of the component.

Published: November 2017

Abstract
Quadcopters are unmanned Ariel Vehicle (UAV), generally small helicopter that is lifted and propelled by four rotors. Initially they were used as toys, later they gained importance and recent research on multi-copters have received growing attention for military, agriculture, photography, surveillance, news, sports, search/rescue missions and much more. The widespread use of unmanned vehicles and its growing applications in various domains can be attributed to their ability to operate in inaccessible areas, thus decreasing the human loss in major accidents, and making access easy to dangerous conditions. We have proposed an idea about how quadcopter can be used for the application of fire detecting and extinguishing. The target of this paper is to explain briefly to prepare a quadcopter so that it could be used for firefighting and can help our society.
Cloud Security and Compliance - A Semantic Approach in End to End Security
Authors: Kalaiprasath R. , Elankavi R. , Udayakumar R. 
Published: November 2017

Abstract
The Cloud services are becoming an essential part of many organizations. Cloud providers have to adhere to security and privacy policies to ensure their users’ data remains confidential and secure. Though there are some ongoing efforts on developing cloud security standards, most cloud providers are implementing a mishmash of security and privacy controls. This has led to confusion among cloud consumers as to what security measures they should expect from the cloud services, and whether these measures would comply with their security and compliance requirements. We have conducted a comprehensive study to review the potential threats faced by cloud consumers and have determined the compliance models and security controls that should be in place to manage the risk. Based on this study, we have developed an ontology describing the cloud security controls, threats and compliances. We have also developed an application that classifies the security threats faced by cloud users and automatically determines the high level security and compliance policy controls that have to be activated for each threat. The application also displays existing cloud providers that support these security policies. Cloud consumers can use our system to formulate their security policies and find compliant providers even if they are not familiar with the underlying technology.
A New Approach for Cloud Data Security: From Single to Cloud-of-Clouds
Authors: Kalaiprasath R. , Elankavi R. , Udayakumar R. 
Published: November 2017

Abstract
In the corporate world, a large number of people store their data on clouds. For doing this they need to give their confidential data in the hands of the third party, commonly known as service providers. These cloud service providers cannot be trusted since the complete data is stored in one single cloud. This increases security risks to the user’s sensitive data. Due to this issue of data integrity risk and service availability failure, the concept of “Cloud-of-Clouds” comes into picture. Cloud-of-clouds are also known as “inter-clouds” or “multi-clouds”. Use of cloud-of-clouds provides a higher level of security to the user’s confidential data. The aim of this paper is to secure the user’s data by using cloud-of clouds.

It also provides a forum for researchers, practitioners and educators to present and discuss the most recent innovations, trends, and concerns, practical challenges encountered and the solutions adopted in these fields.
Sensor Technology at Submillimeter Wavelengths for Space Applications
Authors: Chattopadhyay Goutam 
Published: November 2017

Abstract
Our universe is most luminous at far-infrared and submillimeter wavelengths (100 GHz – 10 THz) after the Cosmic Microwave Background (CMB) radiation. This region of the electromagnetic spectrum provides critical tracers for the study of a wide range of astrophysical and planetary phenomena. This spectral range contains information on the origin of the planets, stars, galaxies, and clusters; the geometry and matter/energy content of the Universe, atmospheric constituents and dynamics of the planets and comets and tracers for global monitoring and the ultimate health of the Earth. Sensors at far-infrared and submillimeter wavelengths provide unprecedented sensitivity for astrophysical, planetary, and earth observing instruments. Very often, for a spaced based platform where the instruments are not limited by atmospheric losses and absorption, the overall instrument sensitivity is dictated by the sensitivity of the sensors themselves. Moreover, some of the cryogenic sensors at submillimeter wavelengths provide almost quantum-limited sensitivity. This paper provides an overview of the submillimeter-wave sensors and their performance and capabilities for space applications.
Human-Based Sensing – Sensor Systems to Complement Human Perception
Authors: Wide Peter 
Published: November 2017

Abstract
The approach of human-based sensing is based on the assumption that sensor systems for individual use have optimal performance if coherent with the human perception system. The benefits of complementing the human sensing with sensor systems that strengthen the information and make the human able to perform more adequate and optimized decisions based on the sensor information, will improve the human capability. The arguments for designing sensor systems that increase the human ability in order to enhance the information from its surroundings are obvious. In this paper, an example of this approach, related to human-based sensing, will be demonstrated. The ability to strengthen the human capability, and complementing human perception with additional sensing, by the use of artificial sensor systems, will increase the human performance.

Published: November 2017

Abstract
An optical fibre sensor for detection of volatile organic compounds (VOCs) has been implemented. This device is based on a vapochromic material presented in the form of bright red powders, which suffers reversible changes in its optical properties when exposed to some organic vapours. The sensor head consists of a nano interferometer doped with the vapochromic material, built onto a cleaved ended multimode optical fibre by using the Layer by Layer Electrostatic Self Assembly Method (LbL). A reflection scheme was used, so the intensity modulated reflected signal is registered in order to study its response. Changes up to 3 dB in the reflected optical power were measured.

A compensating torque, computed from the force sensor reading, is injected into the ankle-joint of the foot of the robot to improve stability. The effectiveness of the method is demonstrated on a humanoid robot, MaNUS-I, to reject disturbances of various form.
An Embedded Wireless System For Estimating The Exposition Risk In First Emergency Management
Authors: Alippi Cesare , Galperti Cristian 
Published: November 2017

Abstract
In this paper we propose the design of a wearable embedded system1 for wirelessly delimiting an hazardous area during emergency, alerting the rescue operators when entering in it and measuring the consequent exposition time. (The dangerous area is previously identified, e.g., through suitable instrumentation). The suggested approach, which is identically effective in indoor and outdoor environments, significantly extends existing solutions by not requiring any absolute position information for delimiting the hazardous area or fixed infrastructure as requested instead by GPS and UWB solutions. The proposed low-power system can be easily retrieved after use and ready to be deployed in a new environment.

Authors: Lay-Ekuakille A. , Vendramin G. , Fedele A. , Vasanelli L. , Trotta A. 
Published: November 2017

Abstract
Solar trackers represent apparatuses that may significantly improve electric power production of photovoltaic panels. For detecting solar position, the trackers use different sensors (e.g. photoresistor, photodiode receiver, phototransistor, etc..). This research proposes an alternative way, the use of the sensor par excellence for retrieving solar radiation; the pyranometer. A design and tests have been performed in order to show the improvements. A comparison has been made between this alternative mounted on a solar follower plant and another tracking system called S.A.I.S. which does not use any solar position sensor but tracks the panel by solar position calculations, from the ad hoc knowledge of longitude, latitude, date and hour. A second comparison has been also made between the above pyranometer architecture and a specifically designed solarimeter

Published: November 2017

Abstract
Mechanical systems or robots to assist landmine detection are expected to greatly improve quality of humanitarian demining tasks. These new systems could provide: i) safer operation; ii) advanced methods for automatic target recognition and discrimination; iii) consistent performance with less influence of “human-factors”; iv) better detection performance, i.e., higher probability of detection (POD) and lower false alarm rate (FAR); among others. However, despite many research/development efforts around the world, no practical landmine detection robot has yet achieved maturity for practical use. Nonetheless, the humanitarian demining robot Gryphon, which current status of development is described in detail, is close to meet the requirements for practical use. This paper analyses the results from latest on-site tests underwent by Gryphon in Croatia (2006, 2007) and Cambodia (2006), to make a critical and objective evaluation of its validity, and clarify the points that still require further development in order to realize a practical humanitarian demining robot

Abstract
This paper presents design concepts in developing an Autonomous Golf Playing Micro Robot. The robot moves autonomously using 2 DC motors controlled by a remote PC using fuzzy logic system. A servomotor is used for the motion of the putter in hitting the golf ball. A microcontroller is used to process the information sent by the computer through RF communication and drive the robot motors for appropriate motions. The robot plays golf in a defined environment and avoids obstacles. A real golf ball with orange color is use during the game. The system utilizes global camera vision that serves as the eyes of the robot to know its dynamic environment for navigation. The vision system developed detects the position of the robot, golf hole, golf boundaries, and the golf ball within the playing field on real time using color object recognition algorithm. A modified golf tournament between autonomous robot golf player and man operated robot golf player was conducted. Results shows the accuracy and robustness of the autonomous robot developed in performing its tasks.
Multi-Target, Multi-Sensor Tracking Based on Quality-Of-Information and Formal Bayesian Frameworks
Authors: Lee Juo-Yu , Yao Kung 
Published: November 2017

Abstract
We consider a multi-target tracking problem that aims to simultaneously determine the number and state of mobile targets in the field. Conventional paradigms tend to report only the existence and state of targets according to centralized detection and data fusion. On the contrary, we investigate a multi-target, multi-sensor scenario in which (a) both the number and the state of the targets are unknown a priori; and (b) the detection with respect to targets is employed in a distributed manner. Toward this end, we exploit random set theory, a statistical tool based on Bayesian framework, for establishing generalized likelihood and Markov density functions to yield an iterative filtering procedure. We conduct a study regarding how the design of distributed detection has impact on the result of system level information fusion. The sources of analyzed data include (a) simulation-based sensor readings through bi-directional sensing/communication; and (b) practical images taken by multiple cameras through uni-directional sensing/communication. The formulation of Bayesian filtering suggests that a design of a tracking system be adaptive to change of detection performance.
Advanced Predictive Guidance Navigation for Mobile Robots: A Novel Strategy for Rendezvous in Dynamic Settings
Authors: Kunwar Faraz , Benhabib Beno 
Published: November 2017

Abstract
This paper presents a novel on-line trajectory planning method for the autonomous robotic interception of moving targets in the presence of dynamic obstacles, i.e., position and velocity matching (also referred to as rendezvous). The novelty of the proposed time-optimal interception method is that it directly considers the dynamics of the obstacles as well as the target in its interception maneuver: the velocities and accelerations of the obstacles and the target are predicted in real-time for potential collisions. The method is designed to deal with highly- maneuvering obstacles and targets. The interception maneuver is computed using an Advanced Predictive Guidance Law.
Extensive simulation and experimental analyses, some of which are reported in this paper, have clearly demonstrated the time efficiency of the proposed rendezvous method.
Impedance Behaviour of a Microporous PMMA-Film ‘Coated Constant Phase Element’ based Chemical Sensor
Authors: Biswas Karabi , Thomas Litty , Chowdhury Sourabh , Adhikari Basudam , Sen Siddhartha 
Published: November 2017

Abstract
In this work, it has been attempted to characterize a new type of impedance sensor called constant phase element (CPE) sensor; which has microporous PMMA-film coating on the electrode surface. It has been shown that the ‘constant phase angle (CPA)’ behaviour is primarily due to the porous structure of the electrode surface. And the phase angle at the output of the sensor changes with thickness variation of the PMMA coating and ionic property of the medium in which the sensor is dipped in. The sensor has been used for chemical sensing. A phase angle detector circuit gives the output in voltage with the change in the phase angle. The complex impedance plots of the probes has also been discussed. The important fact is that the constructed CPE gives rise to a fractional order system.

Published: November 2017

Abstract
The paper describes the development of an FPGA based fuzzy processing system for pulmonary spirometry applications predicting the approaching obstructive or restrictive pulmonary disorder of the patient before criticality actually occurs. The system employs a smart agent that accepts the Peak Expiratory Flow Rate (PEFR), Forced Expiratory Volume in 1 second (FEV1) and Forced Vital Capacity (FVC) data of patients. In order to speed up the computation process, hybrid parallel data processing architectures with dynamic scheduling mechanism have been employed leading to a speed up of approximately 12 times. The processor implemented on the FPGA can perform fuzzy inferencing at a speed of approximately 5.0 MFLIPS. The whole system is realized on Altera Cyclone EP1K6Q240C8 FPGA chip requiring 5,865 logic blocks. The system has been designed to be inexpensive, portable and user friendly for occupational health care applications in developing countries. Using the system, approaching pulmonary disorder of patients has been predicted with an accuracy of 95.83%.
