In this paper, We have implemented an efficient technique for the inactivation of pathogens in the air and on the surfaces of the hospital rooms. These rooms are the main source of the bacterial diseases spreading in the locality and thereby contaminating the environment. So, a new method is taken into account which uses the wavelength light centered at 405 nm for the disinfection process. The inactivation process of bacteria’s is caused by the 405 nm light which targets the intra-cellular porphyrin of the pathogens which absorbs the light and bacteria’s are eliminated due to the generation of reactive oxygen species in their body. This process has been successfully achieved by the proposed model system. This system uses the light source assembly as a primary source that emits the white light in the broad spectrum which ranges from 450-475 nm that lies in the visible spectrum region. Then this broad spectrum white light is passed through the high-intensity narrow band pass optical filter which reduces the wavelength in the range of 400-410 nm having wavelength centered at 405 nm. Along with this, a multi-sensor adaptive feedback network is also applied to the system which changes the intensity level of the disinfecting light depending on the density of the bacteria’s present in the room. This adaptive nature of the system helps in reducing the power consumption by the system which is necessary in case of continuous disinfection process. This method holds an upper hand over the ultraviolet light devices (UV-C) technique which uses the wavelength in the range of 254-360 nm for the disinfection process. Since the 405 nm light lies in the visible spectrum, hence it is safe to use in presence of a person in the room, thus making the system a continuous process for the disinfection.

An antiferromagnetic semimetal has been recently identified as a new member of topological semimetals that may host three-dimensional symmetry-protected Dirac fermions. A reorientation of the Néel vector may break the underlying symmetry and open a gap in the quasiparticle spectrum, inducing the (semi)metal-insulator transition. Here, we predict that such a transition may be controlled by manipulating the chemical potential location of the material. We perform both analytical and numerical analysis on the thermodynamic potential of the model Hamiltonian and find that the gapped spectrum is preferred when the chemical potential is located at the Dirac point. As the chemical potential deviates from the Dirac point, the system shows a possible transition from the gapped to the gapless phase and switches the corresponding Néel vector configuration. We perform density functional theory calculations to verify our analysis using a realistic material and discuss a two terminal transport measurement as a possible route to identify the voltage-induced switching of the Néel vector.

The smart health paradigms employ Internet-connected wearables for tele-monitoring, diagnosis providing inexpensive healthcare solutions. Mist computing reduces latency and increases throughput by processing data near the edge of the network. In the present paper, we proposed a secure mist Computing architecture that is validated on recently released public geospatial health dataset. Results and discussion support the efficacy of proposed architecture for smart geospatial health applications. The present research paper proposed SoA-Mist i.e. a three-tier secure framework for efficient management of geospatial health data with the use of mist devices. It proposed the security aspects in client layer, mist layer, fog layer and cloud layer. It has defined the prototype development by using win-win spiral model with use case and sequence diagram. Overlay analysis has been performed with the developed framework on malaria vector borne disease positive maps of Maharastra state in India from 2011 to 2014 in mobile clients as test case. Finally, It concludes with the comparison analysis of cloud based framework and proposed SoA-Mist framework.

A novel unsupervised method for new word extraction

引用

science China(Information sciences) 2016年第9期59卷 11-21页

作者： Lili MEI Heyan HUANG Xiaochi WEI Xianling MAO Beijing Engineering Research Center of High Volume Language Information Processing and Cloud Computing Applications Department of Computer Science and TechnologyBeijing Institute of Technology

New words could benefit many NLP tasks such as sentence chunking and sentiment analysis. However, automatic new word extraction is a challenging task because new words usually have no fixed language pattern, and even appear with the new meanings of existing words. To tackle these problems, this paper proposes a novel method to extract new words. It not only considers domain specificity, but also combines with multiple statistical language knowledge. First, we perform a filtering algorithm to obtain a candidate list of new words. Then, we employ the statistical language knowledge to extract the top ranked new words. Experimental results show that our proposed method is able to extract a large number of new words both in Chinese and English corpus, and notably outperforms the state-of-the-art methods. Moreover, we also demonstrate our method increases the accuracy of Chinese word segmentation by 10% on corpus containing new words.

We present new practical local differentially private heavy hitters algorithms achieving optimal or near-optimal worst-case error and running time - TreeHist and Bitstogram. In both algorithms, server running time is O(n) and user running time is O(1), hence improving on the prior state-of-the-art result of Bassily and Smith [STOC 2015] requiring O(n5/2) server time and O(n3/2) user time. With a typically large number of participants in local algorithms (n in the millions), this reduction in time complexity, in particular at the user side, is crucial for making locally private heavy hitters algorithms usable in practice. We implemented Algorithm TreeHist to verify our theoretical analysis and compared its performance with the performance of Google's RAPPOR code. Copyright © 2017, The Authors. All rights reserved.

Service composition refers to the process of developing the complex services from existing services. In order to add or remove functionalities of the composite services and to reduce the human intervention, the service composition process should be dynamic, scalable, and reusable. For the purpose, this paper proposes a Colored PetriNet based approach for service composition. In the proposed mechanism, firstly, a conceptual model of service interface has been devised. Based on the conceptual model a Colored PetriNet (CPN) based model, called Colored PetriNet for Service Composition (CPSC) has been proposed to represent the behavioral aspects of the conceptual constructs of service interfaces and different composition aspects of the constituent services. It also implements a service composition algorithm to execute the composition sequence of services. Moreover, the proposed CPSC along with the algorithm are illustrated with a suitable case study and simulated using CPN tool. The result shows that the proposed algorithm can successfully compose services based on the user requirements. Beside these, the state space report of the proposed CPSC validates the standard behavioral properties of the concerned system.

Searchable encryption is a cryptographic primitive used to search an encrypted data in cloud storage. Recently, Cui et al. and Lu et al. proposed two variants of secure searchable encryption schemes, respectively. However, based on our best knowledge we demonstrate that the both schemes are insecure against different types of off-line keyword guessing attacks in this paper. Finally, we make discussions about searchable encryption schemes whether resisting off-line keyword guessing attacks. © 2018, Ubiquitous International. All rights reserved.

The harvesting of ambient radio-frequency (RF) energy is an attractive and clean way to realize the idea of self-powered electronics. Here we present a design for a microwave energy harvester based on a nanoscale spintronic diode (NSD). This diode contains a magnetic tunnel junction with a canted magnetization of the free layer, and can convert RF energy over the frequency range from 100 MHz to 1.2 GHz into DC electric voltage. An attractive property of the developed NSD is the generation of an almost constant DC voltage in a wide range of frequencies of the external RF signals. We further show that the developed NSD provides sufficient DC voltage to power a low-power nanodevice - a black phosphorus photo-sensor. Our results demonstrate that the developed NSD could pave the way for using spintronic detectors as building blocks for self-powered nano-systems, such as implantable biomedical devices, wireless sensors, and portable electronics.
