A Survey Paper on Privacy Preserving and Content Protecting Location Based Queries Using Two Phase Protocol

Location Based Service LBS is the service accessed on mobiles or devices with GPS. In order to use these services there are certain issues to the data being shared and the information of the user who is using this service may be exposed publicly, even though the user doesnot want to share his information in public domain. A lot of research has been done over this, to protect the users data to be accessed by unauthorised users and those who are not the intended users of that information. We propose a solution to one of the location-based query problems. A user wants to query a database of location data, known as Points of Interest (POIs), and does not want to reveal his/her location to the server due to privacy concerns; And the owner of the location data, that is, the location server, does not want to simply distribute its data to all users

Implementation of Decoy Deception based Detection System for Ransomware Attack

Ransomware poses a dangerous threat to  cybersecurity. Data as well as rights owned by the user are  adversely impacted. The situation has become considerably  more critical as a result of the emergence of new ransomware  varieties and Ransomware-as-a-Service. In this paper, we  presented a novel deception-based and behaviour-based  method for real-time ransomware detection. In order to avoid  any loss before ransomware is discovered, we build pretend  files and directories for nefarious behaviours. We conducted a  pilot study using Locky, and the results demonstrate the  effectiveness of our strategy with little system resource usage  and geographical cost.&nbsp

Role Based Secure Data Access Control for Cost Optimized Cloud Storage Using Data Fragmentation While Maintaining Data Confidentiality

The paper proposes a role-based secure data access control framework for cost-optimized cloud storage, addressing the challenge of maintaining data security, privacy, integrity, and availability at lower cost. The proposed framework incorporates a secure authenticity scheme to protect data during storage or transfer over the cloud. The framework leverages storage cost optimization by compressing high-resolution images and fragmenting them into multiple encrypted chunks using the owner's private key. The proposed approach offers two layers of security, ensuring that only authorized users can decrypt and reconstruct data into its original format. The implementation results depicts that the proposed scheme outperforms existing systems in various aspects, making it a reliable solution for cloud service providers to enhance data security while reducing storage costs

Impact of an International Nosocomial Infection Control Consortium multidimensional approach on central line-associated bloodstream infection rates in adult intensive care units in eight cities in India

SummaryObjectiveTo evaluate the impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control approach on central line-associated bloodstream infection (CLABSI) rates in eight cities of India.MethodsThis was a prospective, before-and-after cohort study of 35650 patients hospitalized in 16 adult intensive care units of 11 hospitals. During the baseline period, outcome surveillance of CLABSI was performed, applying the definitions of the CDC/NHSN (US Centers for Disease Control and Prevention/National Healthcare Safety Network). During the intervention, the INICC approach was implemented, which included a bundle of interventions, education, outcome surveillance, process surveillance, feedback on CLABSI rates and consequences, and performance feedback. Random effects Poisson regression was used for clustering of CLABSI rates across time periods.ResultsDuring the baseline period, 9472 central line (CL)-days and 61 CLABSIs were recorded; during the intervention period, 80898 CL-days and 404 CLABSIs were recorded. The baseline rate was 6.4 CLABSIs per 1000 CL-days, which was reduced to 3.9 CLABSIs per 1000 CL-days in the second year and maintained for 36 months of follow-up, accounting for a 53% CLABSI rate reduction (incidence rate ratio 0.47, 95% confidence interval 0.31–0.70; p=0.0001).ConclusionsImplementing the six components of the INICC approach simultaneously was associated with a significant reduction in the CLABSI rate in India, which remained stable during 36 months of follow-up

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.

Fluidically Driven Systems for Tangible and Interactive Media

The possibility of augmenting existing 3D-interaction devices for virtual reality with haptic feedback has generated wide interest in the field of human-computer Interaction. Designing interaction devices for haptic feedback is challenging due to the densely packed mechanoreceptors on the skin distributed over a large surface area. The widely used solution for the design of haptic interfaces rely on solid-state electronic components such as piezoelectric actuators, voice coils, vibrotactile actuators, or electromagnets that are built with rigid materials. Integrating these electronic components with textiles to match the spatial density of the mechanoreceptors on the skin can cause discomfort. Additionally, the rigid nature of these devices can limit them from conforming to the complex topological surfaces of the human body. The emerging field of soft robotics has the potential to address these challenges by replacing traditional actuators with unconventional materials that have mechanical properties close to those of human tissue. Various actuation strategies in soft robotics (including pneumatic, hydraulic, thermal, and electromechanical actuation) have been previously presented for applications in haptic devices. Fluidic systems have been widely explored in haptics due to their ability to enable actuators with ease of use. However, most fluidic systems control these actuators with individually addressable electromechanical valves, which make the system difficult to scale in number, to achieve the spatial density desired for haptic interfaces. Additionally, the nonlinear nature of elastomeric devices makes the stable, closed-loop control of such systems very complex. In this dissertation, I describe strategies to simplify the design and control of fluidically actuated systems to enable their application to wearable haptic interfaces and interactive media. First, I present the concept of "Fiber Jamming'', a mechanism to achieve variable stiffness by controlling the input pressure in an actuator. I demonstrate the application of fiber jamming using open-loop control in a variable-stiffness haptic glove and a reconfigurable truss structure. Next, I present a dot-matrix-inspired fluidic circuit to individually address actuators in a large array. I demonstrate the application of the fluidic circuit using 10 electromechanical valves to individually address a 2D-Shape Display with 25 actuators. Additionally, I also demonstrate the application of the fluidic circuit to actuate a haptic vest with an array of inflatable pouches. Finally, I present strategies for the design and evaluation of 3D designs to overcome the limitations of the existing 3D-input devices to facilitate tasks requiring precision. I present a tool for three interactions in three dimensions for the design and prototyping of structures in engineering applications. The first two techniques demonstrate how the design and control of fluidic systems can be simplified without compromising their rapid rates of actuation and ease of use. The 3D-interface design and evaluation strategies present techniques to design and evaluate VR applications to enable precision tasks. Overall, the results demonstrate strategies for realizing ubiquitous tangible interfaces for applications in wearable haptic interfaces and exoskeletons

Virtual Reality based User Interface for Conceptual Design and Rapid Prototyping

Computer Aided Design and Engineering (CAD/ CAE) tools currently available in the market have dramatically improved since their inception. In product development, CAD/ CAE has enabled the user to design, test, analyze and optimize the product virtually even before the first prototype is built. Use of direct modeling for product conceptualization allows the designer to create concept design iterations freely, quickly, flexibly and fast optimization. While modeling geometric databases have been 3D since long time, the interaction technology still uses 2D input devices like mouse, with Virtual Reality (VR) as a standalone visualization tool. Over the years, it has been recognized that the conventional 2D input devices for entering 3D shape information makes the interaction cumbersome and negatively affect creativity. This research focuses on design of virtual reality based user interface for automotive chassis design Virtual reality based user interface is developed to iteratively design and prototype various automotive chassis concepts. The tools for ergonomic analysis and center of mass visualization enable the user to rapidly optimize the design in VR. The VR environment is interfaced with commercial finite element software to test the design concepts for structural integrity. Virtual constrains aid modeling tasks and minimize the processing effort required on the conceptual model to a parametric model. The thesis is concluded with a preliminary cognitive walkthrough study. The VR based user interface can allow the user to rapidly test various design concepts quickly, and flexibly. The user interface can reduce the concept to market time, enhance creativity, and reduce the total cost of product development. This interface can be a stepping stone for the future VR based CAD interfaces
