The deployment of biosensors is increasing with advancement of bio-electronics. Owing to challenging state of working of biosensors, the present applications of biosensors are capable of capturing only certain types of signals till date. This detection also depends on the type of the bio transducers used for signal generation and therefore, the signals generated from biosensors cannot be considered to be error free. This paper has reviewed some of the existing research contributions towards biosensor validation to find that there are no computational framework that efficiently performs validation as majority of the technique uses either clinical approach or experimental approach, which limits the validation of bio signal performance. Therefore, this paper presents a novel computational framework that uses enhanced version of auto-associative neural network and significantly optimizes the validation performance of biosensors as compared to other conventional optimization techniques.
随着生物电子学的发展,生物传感器的应用越来越广泛。由于生物传感器的工作状态具有挑战性,目前应用的生物传感器只能捕获某些类型的信号。这种检测还取决于用于信号产生的生物传感器的类型,因此,从生物传感器产生的信号不能被认为是没有误差的。本文回顾了对生物传感器验证的一些现有研究贡献,发现没有有效执行验证的计算框架,因为大多数技术使用临床方法或实验方法,这限制了生物信号性能的验证。因此,本文提出了一种新的计算框架,该框架使用增强版的自关联神经网络,与其他传统优化技术相比,显著优化了生物传感器的验证性能。

Heterogeneity and complexity of distributed computing increases rapidly as high speed processors are widely available. In modern computing environment, resources are dynamic, heterogeneous, geographically spread over different computational domains and connected through different capacity of high speed communication links. In a large distributed environment a modular program can be considered as a set of loosely coupled interacting modules/tasks (since all the modules/tasks are considered as simultaneously and independently executable) and represented by task interaction graph (TIG) model. Parallel execution of these interacting modules/tasks is highly preferred to reduce the overall completion time of a program. During parallel execution of tasks, the communication overhead due to message passing may increase the cost of parallel execution. Parallel execution of tasks is chosen if and only if parallel execution cost together with communication overhead is less than serial execution cost. So, resources are to be allocated such that advantage of parallel execution is maintained. In this paper, for any task and resource graph, we propose a heuristics based approach to find out an optimal number of tasks that can be executed in parallel on a set of resources where they can be executed.
随着高速处理器的广泛应用,分布式计算的异构性和复杂性迅速增加。在现代计算环境中,资源是动态的、异构的,地理上分布在不同的计算域中,并通过不同容量的高速通信链路连接起来。在大型分布式环境中,模块化程序可以被认为是一组松散耦合的交互模块/任务(因为所有模块/任务都被认为是同时独立执行的),并由任务交互图(TIG)模型表示。这些相互作用的模块/任务的并行执行是非常可取的,以减少程序的总体完成时间。在并行执行任务期间,由于消息传递而产生的通信开销可能会增加并行执行的成本。当且仅当并行执行成本和通信开销小于串行执行成本时,选择并行执行任务。因此,要分配资源,以保持并行执行的优势。在本文中,对于任何任务和资源图,我们提出了一种基于启发式的方法来找出可以在一组可以执行的资源上并行执行的任务的最佳数量。

Satellite Data concisely convey information about positions, sizes and interrelationships between objects. The satellite image losses information due to lack of Acquisition capability of sensor and atmosphere's effect. It is very difficult to extract useful information at intensity level with low SNR, non wavelet segmented schemes losing high frequency contact with results texture is blurred several preprocesses are applied to make textual image clear and segmentation. Unsatisfied results due with lack of directionality with DWT, Here we can implement advance image processing technique for improving texture based features to multispectral satellite image, find discrepancy distribution of observed and normal region using Higher order statistical methods(HOS) like skewness, Kurtosis. The shape of the distribution of intensity levels are examined by HOG. For improving the visualization quality we examine features based on edges, lines and their gradients using Curvelet and Histogram of oriented Gradient (HOG), intensity distribution using Higher order Statistics (HOS).
卫星数据简洁地传达了物体之间的位置、大小和相互关系的信息。由于传感器的获取能力不足和大气的影响,卫星图像信息丢失。在低信噪比的情况下,在强度级提取有用信息非常困难,非小波分割方案失去了与结果的高频接触,纹理模糊,采用了多种预处理方法使文本图像清晰和分割。本文采用基于纹理特征的高级图像处理技术对多光谱卫星图像进行改进,利用偏度、峰度等高阶统计方法(HOS)找出观测区与正态区的差异分布。强度水平分布的形状由HOG检验。为了提高可视化质量,我们使用曲线和定向梯度直方图(HOG)检查基于边缘、线条及其梯度的特征,使用高阶统计量(HOS)检查强度分布。

This paper presents a new optimized DWT-SVD based watermarking technique using Genetic Algorithm. The singular value component of the original Image is modified by adding the singular component of the watermark image along with a suitable scaling factor. This scaling factor is optimized by GA using the PSNR values as the fitness criteria in order to achieve high values or robustness without compromising the transparency of the watermark. Further application based analysis is done by using the Noise Correlation as a fitness function to test for better results in robustness.
提出了一种基于遗传算法的优化DWT-SVD水印技术。通过加入水印图像的奇异分量和适当的比例因子,对原始图像的奇异值分量进行修正。该比例因子通过遗传算法以PSNR值作为适应度标准进行优化,从而在不影响水印透明度的情况下实现高值或鲁棒性。进一步的基于应用的分析是通过使用噪声相关作为适应度函数来测试鲁棒性的更好结果。

Adjacent Evaluation of Completed Local Ternary Count for Texture Classification 纹理分类中局部已完成三元计数的邻域评价
Pub Date : 1900-01-01 DOI: 10.1109/IACC.2017.0144

Local Binary Pattern (LBP) is one of the successful texture analysis methods. However, LBP suffers from noise robustness and rotation invariance. This paper proposes a novel noise insensitive texture descriptor, Adjacent Evaluation Local Ternary Count (AELTC) for rotation invariant texture classification. Unlike LBP, AELTC uses an adjacent evaluation window to change the threshold scheme. It is enhanced to Adjacent Evaluation Completed Local Ternary Count (AECLTC) with three operators to improve the performance of texture classification. During the performance evaluation, various experiments are conducted on Outex and CUReT databases using seven existing LBP variants and with proposed AECLTC. The results demonstrated the superiority of AECLTC when compared to other LBP variants.
局部二值模式(LBP)是一种成功的纹理分析方法。然而,LBP具有噪声鲁棒性和旋转不变性。提出了一种新的对噪声不敏感的纹理描述子——邻值局部三元计数(AELTC),用于旋转不变纹理分类。与LBP不同,AELTC使用相邻的评估窗口来改变阈值方案。为了提高纹理分类的性能,将其改进为使用三个算子的邻域评估完成局部三元计数(AECLTC)。在性能评估过程中,使用七个现有的LBP变体和提出的AECLTC在Outex和CUReT数据库上进行了各种实验。结果表明,与其他LBP变体相比,AECLTC具有优势。

Pub Date : 1900-01-01 DOI: 10.1109/IACC.2017.0031
M. Vikram, N. Reddy, K. Madhavi
Now-a-days, Speech Recognition had become a prominent and challenging research domain because of its vast usage. The factors affecting Speech Recognition are Vocalization, Pitch, Tone, Noise, Pronunciation, Frequency, finding where the phoneme starts and stops, Loudness, Speed, Accent and so on. Research is going on to enhance the efficacy of Speech Recognition. Speech Recognition requires efficient models, algorithms and programming frameworks to analyze large amount of real-time data. These algorithms and programming paradigms have to learn knowledge on their own to fit in to the model for massively evolving data in real-time. The developments in parallel computing platforms opens four major possibilities for Speech Recognition systems: improving recognition accuracy, increasing recognition throughput, reducing recognition latency and reducing the recognition training period.
如今,语音识别因其广泛的应用而成为一个突出而具有挑战性的研究领域。影响语音识别的因素有发声、音高、音调、噪音、发音、频率、寻找音素开始和停止的位置、响度、速度、口音等等。提高语音识别效能的研究正在进行中。语音识别需要高效的模型、算法和编程框架来分析大量的实时数据。这些算法和编程范例必须自己学习知识,以适应实时大规模发展数据的模型。并行计算平台的发展为语音识别系统提供了四个主要的可能性:提高识别精度、增加识别吞吐量、减少识别延迟和缩短识别训练周期。

Stack Solution for Finding Optimal One 寻找最优解的堆栈解
Pub Date : 1900-01-01 DOI: 10.1109/IACC.2017.0159
P. Kumar, G. Sahoo
In comparative genomics, genome rearrangement evolution is an important effort. Genome conversion is the major problem in this field using different sorting process. Transforming one sequence into another and finding an optimal solution is a useful tool for analyzing real evolutionary scenario but it will be much better if we find all possible solution for that. In order to obtain more accurate result, some solution should be taken into consideration as there is large number of different optimal sorting sequence. Reversal and translocation are the two common genome sorting process used in development of mammalian species. The problem of genome sorting using reversal and translocation is to find the shortest sequence that transforms any source genome A into some target genome B. Currently the question is resolved by lessening of sorting by reversal and sorting by translocation problem separately, but here we are applying both the sorting process together at the same time. By this paper we present an algorithm for the two sorting process that explicitly treats them as two distinct operations, along with that finding the various solutions which is a better hypothetical and real-world solution than just finding a solo one. If we have single solution for any problem then we cannot decide whether this solution is the perfect one or not but if we have more solution indeed we can find the best one among them and say this is the perfect solution. We also present an example which proves that this solution is more prominent than previous one.
在比较基因组学中,基因组重排进化是一个重要的研究方向。基因组转换是该领域的主要问题,采用不同的分选工艺。将一个序列转换为另一个序列并找到最优解是分析真实进化场景的有用工具,但如果我们能找到所有可能的解决方案,那就更好了。由于存在大量不同的最优排序顺序,为了获得更准确的结果,需要考虑一定的解。逆转和易位是哺乳动物物种发育中常见的两种基因组分选过程。利用反转和易位进行基因组排序的问题是找到将任意源基因组A转化为目标基因组b的最短序列,目前这个问题是分别通过减少反转排序和易位排序来解决的,但这里我们同时应用了这两种排序过程。通过本文,我们提出了一种算法,用于两个排序过程,明确地将它们视为两个不同的操作,以及寻找各种解决方案,这是一个更好的假设和现实世界的解决方案,而不仅仅是寻找一个单独的解决方案。如果我们对任何问题都有单一的解决方案,那么我们无法决定这个解决方案是否是完美的解决方案,但如果我们有更多的解决方案,我们可以找到其中最好的一个,并说这是完美的解决方案。最后给出了一个算例,证明了该解比之前的解更加突出。

Emerging sensor based electronic gadgets desire to seek high levels of energy conservation by adopting extreme low power techniques in combination with traditional techniques. In this study the authors examine memory units with data retention capability in the Energy-Delay space for an emerging application namely Transiently Powered System for three levels of power and performance optimization. The study presents a novel Dual Edge Triggered Flip-Flop (DETRFF) with retention latch that is suitable for ultra low power application with dynamic voltage switch between super and sub threshold levels. The DETRFF designs are simulated in 45nm NCSU CMOS technology using Cadence. The proposed design excels in the EDP and Leakage Energy metrics as compared to the existing DETFF designs.

ISRO Satellite Centre of the Indian Space Research Organization develops satellites for variety of scientific applications like communication, navigation, earth observation and many more. These satellites consist of very complex intensive systems which carry out advanced mission functions. Hence software plays a critical constituent for mission success. Some of the geostationary missions onboard software is finalized, changes are minimal for the new spacecraft. This model based system for software change analysis for embedded systems deals with managing changes to existing software items and re configuring in any part of development life cycle. This model helps in handing change management, such as maintenance of a component library, predicting the impacts of changes in reused modules, analyzing the behavior of the combination of reused modules. The use of reusable software modules has augmented the development of embedded software for GSAT series of satellites. This model mainly reduces the time during each phase of software life cycle when the changes are to be implemented within short span of time. This paper describes how complete traceability can be established between specifications and design requirements, model elements and their realization.

This paper describes how complete traceability can be established between specifications and design requirements, model elements and their realization.","PeriodicalId":248433,"journal":{"name":"2017 IEEE 7th International Advance Computing Conference (IACC)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116323627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Video quality assessment aims to compute the formalmeasure of perceived video degradation when video is passedthrough a video transmission/processing system. Most of theexisting video quality measures extend Image Quality Measuresby applying them on each frame and later combining the qualityvalues of each frame to get the quality of the entire video. Whencombining the quality values of frames, a simple average or invery few metrics, weighted average has been traditionally used. In this work, saliency of a frame has been used to compute theweight required for each frame to obtain the quality value ofvideo. The goal of every objective quality metric is to correlateas closely as possible to the perceived quality, and the objectiveof saliency is parallel to this as the saliency values should matchthe human perception. Hence we have experimented by usingsaliency to get the final video quality. The idea is demonstratedby using a number of state of art quality metrics on some of thebenchmark datasets.
视频质量评估旨在计算视频通过视频传输/处理系统时感知到的视频退化的正式度量。大多数现有的视频质量度量扩展了图像质量度量,将它们应用于每帧,然后结合每帧的质量值来获得整个视频的质量。当组合帧的质量值时,传统上使用简单平均或很少的度量,加权平均。在这项工作中,一帧的显著性被用来计算每帧所需的权重,以获得视频的质量值。每个客观质量度量的目标都是尽可能与感知质量紧密相关,显著性的目标与此平行,因为显著性值应该与人类感知相匹配。因此,我们尝试使用显著性来获得最终的视频质量。这个想法通过在一些基准数据集上使用一些最先进的质量指标来证明。
