Real world Automatic Speech Recognition (ASR) system development requires rigorous performance review under varying real world conditions. This paper reports our effort on ASR resource creation, transcription, system building and performance assessment for connected and continuous word applications in Bengali language (ranked seventh worldwide) using GMM-HMM and DNN framework on available open source toolkits. Baseline models are built from merging Bengali dataset hosted on government sites with application specific 100 hours indigenous audio collected under target deployment scenario. After feedback analysis of live systems by real users, novel Error Handling Techniques like Signal Analysis and Decision, Confidence based ASR output Polling and Runtime LM are implemented which results around 2%-11% overall gain in WER with encouraging task success rates in final field trials. Results suggest that recent approaches along with application, environment, target user and runtime resource specific appropriate strategies will yield better acceptability of live ASR systems in India. © SLTU 2018.

Climate change directly affects public health as it significantly influences the emergence and spread of epidemics. Factors such as temperature, precipitation majorly impact and promote the growth of prevalent diseases transmitted by vectors and water-borne diseases as seen from historical and contemporary evidence. We will see in this research work the correlation of various diseases like dengue, cholera, acute diarrheal disease and malaria with temperature for example dengue and malaria have a good correlation with temperature and cholera on the other hand usually outbreaks with anomalies with precipitation showing a good correlation with the precipitation factor. Collection of high quality data has become a must to be able to foster the growth of climate health models in understanding and predicting disease outbreaks due to climate variability. Innovative developments in weather and climate science, especially through AI-enabled numerical weather prediction, AI-NWP, boost confidence in forecasting key variables such as temperature and precipitation. However, a major obstacle to the integration of climate models with health prediction systems lies in the inaccessibility of comprehensive, publicly accessible health datasets for various diseases. Such data sets, especially on granular spatial and temporal scales, are crucial to advance climate health research and model development. In this paper we present the first weekly district-wise dataset for major epidemics spanning across India from 2009 to 2022. The data utilized in this study has been sourced from the Integrated Disease Surveillance Programme(IDSP),a publically available database maintained by the Government of India. This dataset, named "EpiClim: India’s Epidemic-Climate Dataset", bridges the gap by providing detailed insights into health data tailored for climate-health modeling. The data set offers insight into the temporal and spatial dynamics of diseases such as dengue, malaria, and acute-diarrheal di

Indian Sign Language (ISL) is used as the mode of communication among deaf people in India. Currently videos, audio files, and any other synchronized or time-based media are not accessible to deaf or hard of hearing. The proposed Generative adversarial network (GAN) based system will automatically convert text or transcriptions from audio/video file to sign language in avatar form will aid them to understand the content in the media files. It is achieved by breaking down the conversion into two sub-processes. Text is converted to gloss sequences using Neural Machine Translation (NMT), and then it is converted to ISL pose sequences using GAN followed by generating corresponding avatar. Experimental results showed that the proposed sign language interpretation provides richer and more equivalent access to synchronized media © 2022 IEEE.

Due to the onset of the Covid-19 pandemic, people are compelled to maintain social distance in all spheres of life, forcing people to adopt virtual mode of activity. Usage of social media and other internet activity has shot up in this period, and consequently, cybercrimes have also increased. If cybercrimes are reported, computer forensics analysts will examine the concerned website, online forum, or social media to find meticulous details about the cybercrime. But webpage content seen on the day may not be available on the next day. The contents of the webpage, which is the subject of crime, will be deleted or withdrawn, or deactivated to destroy evidence to escape from legal proceedings. The victims usually produce a screenshot of the webpage or image or video as a piece of evidence. But there is a distinct possibility of manipulating the offensive materials and it may not be considered a valid piece of evidence before the court of law. Such a scenario requires a forensic technique that should acquire the content of the webpage before it is removed from web site to maintain the authenticity of captured data. So, we are proposing an automated system for the forensic acquisition of a website that will effectively capture all content from the live website and make it useful for forensic investigation and may be produced before the court as valid evidence of cybercrime. © 2022 IEEE.

Testing is an integral part of software development. The goal of software testing is to find faults from developed software and to make sure they get fixed. It is important to find the faults as early as possible because fixing them is more expensive in the later phases of development. The purpose of testing is also to provide information about the current state of the developed software from the quality perspective. © 2012 IEEE.

Peptide Nucleic Acids (PNA) that bind sequence specifically to DNA/RNA are of major interest in the field of molecular biology and could form the basis for gene-targeted drugs. Molecular dynamics simulations are aimed to characterize the structural and dynamical features to understand the effect of backbone modification on the structure and dynamics along with the stability of the resulting 10mer complexes of PNA with DNA/RNA. Twelve Molecular Dynamics (MD) simulations of duplexes and triplexes with and without cyclohexyl modification were carried out for 10ns each. The simulations indicate that the cyclohexyl modification with different stereoisomers has influenced all the PNA-DNA/RNA complexes. Modification has added rigidity to backbone by restricting β to in case of (1R,2S) cyclohexyl PNA and to ?60 in case of (1S,2R) cyclohexyl PNA. The results of MD simulations were able to show the backbone rigidification and preference for RNA complexes over DNA due to presence of cyclohexyl ring in the PNA backbone.

The realization of certain computational problems using quantum mechanics opened up interesting new possibilities which may be better and beyond the scope of classical supercomputers. Simulation of quantum circuits on classical computers is necessary to analyze the properties of superposition and entanglement. Here, we used the SDKs of optimized libraries and tools of cuQuantum for accelerating quantum computing workflows on FP64 and TF32 based accelerated system for performance analysis. In this paper, the performance of quantum algorithms (Shor's algorithm, Quantum Fourier Transformation, and Sycamore circuit), implemented by the CIRQ simulator, is analyzed on the PARAM HPC-AI system. Execution time and relative speed up for CPU only and accelerators having multiple precision capability enabled run is discussed in detail on PARAM Siddhi-AI system. The graphs are plotted to give a real-Time analysis of the quantum circuit algorithms with the increase in the number of qubits. For Shor's algorithm, Quantum Fourier Transformation, and Sycamore circuit, the maximum speed up, between CPU only and GPU enabled run, is observed as 143x, 115x, and 104x for 30, 32, and 32 qubits respectively. © 2022 IEEE.

The superior performance:power ratio of accelerators is motivating new cluster architectures with varied accelerator combinations. Monitoring ensures normal functioning of the cluster by detecting service degradations and prompt rectification. This paper describes a modular and extendable monitoring framework for heterogeneous multi-accelerator clusters which will be useful for future HPC systems. The framework can support third party software plugins to provide different functional features. A monitoring tool has been developed on the basis of this framework to monitor CPU, GPGPU and FPGA accelerators, network, storage, user jobs and other relevant services of a heterogeneous cluster;the tool is also capable of auto rectification to a certain extent. © 2014 IEEE.

Electromyography signals are used for biomedical applications and clinical diagnosis. This paper presents a system to acquire high quality EMG (electromyography) signal and compress it for high data transfer rate. For acquiring EMG signals we are using off-the-shelf integrated circuit AFE which generates 24 bit data stream output. After acquiring the signal from front end amplifier, the signal is processed (filtration, compression). This is achieved by making use of MSP430 MCU (micro controller). We are using AFE and MSP430 because it is less power consuming, reliable, and both are compatible with each other. The detail of the hardware and software is explained in the further section of the paper. This paper also describes the compression algorithm. Compression is done so that whenever the data is send wirelessly using Bluetooth, Zigbee etc, it requires less bandwidth. © 2013 IEEE.

MULTILOCATION PLANT SIZING AND TIMING PROBLEM - ANALYSIS OF SPATIAL DECOMPOSITION PROCEDURE

引用

INTERNATIONAL JOURNAL OF PRODUCTION ECONOMICS 1993年第3期29卷 249-257页

The multilocation plant sizing and timing problem (MLPSTP) is an important strategic management problem which involves determination of size, location, time-phasing and utilization of projects to meet the demands of spatially distributed customers. The objective for the analysis of such a problem has been to minimize the net present worth of the capital costs as well as the streams of operating and transportation costs. MLPSTP is a mixed integer programming problem involving both binary and continuous variables. The continuous variables relate to the transportation of commodities from site to market. The binary variables problem relates to the size, location and time-phasing of the projects. In this paper, an attempt has been made to analyse the problem by using hierarchical decomposition procedures. The approach has been to construct a two-level hierarchy;the first level identifying the distinct geographical areas as independent subproblems, and the second level being the coordination level which aims at synthesizing the solutions of the area subproblems.
