Sandip Desai, C. Gode, P. Fulzele
In the field of pharmaceutical industry, botany and agricultural there is a need of algorithm which will classify the flowers by processing its image. In this context, we propose a flower classification approach based on convolutional neural network. We have applied transfer learning approach for classification of flowers. We have used VGG19 convolution neural network architecture for extraction of features. As we wanted to classify flowers in 17 different classes so we have used 17 neurons in final dense layer of VGG19 convolution neural network architecture with the use of softmax activation function. Results show that we have classified flowers with the validation accuracy of 91.1 % and training accuracy of 100%.

Capacitive Analysis of Superjunction Vertical IGBT with Gate Engineering 基于栅极工程的超结垂直IGBT电容性分析
Namrata Gupta, Alok Naugarhiya
This paper proposed a 1.4kV-class superjunction vertical IGBT (DMG-SJIGBT) with gate workfunction variation along with stepped oxide thickness. Two distinct workfunction materials, P+ and N+ polysilicon are used as gate poly and oxide thickness is varied in x-direction. All the stepped oxide is connected via metal on the top. The proposed structure's gate oxide is narrow at the emitter and wide at the collector to improve the device performance. It has been discovered that the ON-resistance (Ron.A) of the DMG-SJIGBT has been diminished by 23% as a result of this structural modification. Gate engineering improves the transconductivity by increasing the gate-emitter capacitance (CGE) and reducing the gate-collector capacitance (CGC), which lowers switching delay. To improve performance metrics, the gate length has been optimized. A mixed mode module of SILVACO has used to perform capacitance-voltage analysis. Further the gate charge and FOM has also been measured and indicating 36% and 34% respectively reduction for proposed device signifying enhanced performance.
提出了一种栅极功函数随台阶氧化层厚度变化的1.4 kv级超结垂直IGBT (DMG-SJIGBT)。两种不同的工作功能材料,P+和N+多晶硅被用作栅极多晶硅,氧化物的厚度在x方向上变化。所有的阶梯式氧化物通过顶部的金属连接。该结构的栅极氧化物在发射极处较窄,在集电极处较宽,以提高器件性能。结果发现,DMG-SJIGBT的导通电阻(ron - a)由于这种结构修饰而降低了23%。栅极工程通过增大栅极-发射极电容(CGE)和减小栅极-集电极电容(CGC)来提高导通率,从而降低开关延迟。为了提高性能指标,对栅极长度进行了优化。使用SILVACO的混合模式模块进行电容电压分析。此外,还测量了栅极电荷和FOM,表明所提出的器件分别降低了36%和34%,表明性能增强。

Entity Recognition in Indian Sculpture using CLAHE and machine learning 基于CLAHE和机器学习的印度雕塑实体识别
Ayush Dalara, Dr. Sindhu C, R. Vasanth
Sculpture recognition is one of the most challenging problems in the image classification field due to the high variations in the design of various sculptures. In order to classify the Indian entity's sculpture, we require images from multiple perspectives with different orientations of the structure. This research conducts a comparative study by combining various algorithms for the purpose of sculpture recognition based on their features. The SIFT (Scale Invariant Feature Transform) algorithm was used to find descriptors for the key points detected and it was paired with various classifiers (K-Nearest Neighbors, Support Vector Machine, Artificial Neural Network) by using the “Min key”, “Max key padding”, “Mean key padding”, “Median key padding” and “Mode key padding” approach for efficiency testing purposes. CNNs (Convolutional Neural Networks) were also tested for the same. The models were trained on various representations of different Indian sculptures, gathered from various sources, signifying our cultural diversity. Experiments were carried out on the manually acquired data set that consists of 15 different sculpture classes, where each sculpture class consists of 150 images for training and 20 for testing. An attempt was also made to increase the efficiency of these models by the application of CLAHE (Contrast Limited Adaptive Histogram Equalization). The experiments showed the performance of these models when they were trained on various representations of sculpture images. For 15 different sculpture classes, the maximum accuracy achieved was a respectable 70.66% utilizing the CLAHE along with the CNN model. However, the accuracy values of non-CNN-based approaches were substandard.
雕塑的识别是图像分类领域中最具挑战性的问题之一,因为各种雕塑的设计差异很大。为了对印度实体的雕塑进行分类,我们需要从不同结构方向的多个角度拍摄图像。本研究结合各种算法,根据其特征进行雕塑识别的比较研究。使用SIFT (Scale Invariant Feature Transform)算法寻找检测到的关键点的描述符,并使用“最小键”、“最大键填充”、“平均键填充”、“中位数键填充”和“模式键填充”方法与各种分类器(K-Nearest Neighbors,支持向量机,人工神经网络)配对,以进行效率测试。cnn(卷积神经网络)也进行了相同的测试。模特们接受了不同印度雕塑的训练,这些雕塑来自不同的来源,象征着我们的文化多样性。在人工获取的数据集上进行实验,该数据集由15个不同的雕塑类组成,其中每个雕塑类由150张用于训练的图像和20张用于测试的图像组成。并尝试应用CLAHE(对比度有限自适应直方图均衡化)来提高这些模型的效率。实验显示了这些模型在接受各种雕塑图像表征训练时的表现。对于15个不同的雕塑类,利用CLAHE和CNN模型实现的最大精度是可观的70.66%。而非基于cnn的方法的准确率值不达标。

Comparative Performance Analysis of Spatial Domain Filters for Removing Speckle Noise in SAR images 空域滤波器去除SAR图像散斑噪声的性能比较分析
Ranjith Kumar Painam, M. Suchetha
In synthetic aperture radar (SAR) images, speckle noise is common, and SAR data is handled coherently. Multiplicative noise is another name for speckle. The purpose of this paper is to compare several approaches for reducing speckle noise. These techniques will be used to demonstrate trends and numerous different approaches that have evolved over the years. The technical aspects of the various adaptive spatial domain filters were discussed in this paper, and they were summarised for use in removing speckle noise from SAR images. ENL, SSI, and SSIM are the performance parameters that have been quantitatively and qualitatively analysed. It indicates that the adaptive filters with varied window sizes can be used to eliminate speckle and that noise suppression is more effective in SAR images. It may be enhanced to incorporate several machine learning techniques to optimise the result in order to improve various performance parameters. The experimental results show that the structural details are better preserved while speckle noise is suppressed.

Modeling and Analysis of Hybrid Quadratic Boost Converter in MATLAB/Simulink Environment 混合二次升压变换器在MATLAB/Simulink环境下的建模与分析
Ramprasath Selvaraj, K. Chittibabu, Muthumariyammal Anandharaj, Rameshbabu Perumal
This work presents a systematic and analytical investigation of non-isolated Hybrid Quadratic Boost Converter (HQBC) topology from the Reduced Redundant Power Processing (R2P2) converter family. The voltage conversion is performed by a single switch with a pair of inductor and capacitor. Due to the suggested HQBC quadratic behavior, significant voltage gain may be attained with a modest variation in duty cycle. The theoretical study of the converter's effective step-up voltage ratio and current stresses under continuous conduction mode, are emphasized. Steady state and dynamic modeling were used to examine the behavior of proposed converter. Steady state average equation was derived and a model was designed for 500 w and simulated in MATLAB/ Simulink. The Design and performance analysis of the suggested converter typologies is validated by simulation results.

Shushma Gb, I. Jacob
The speech emotion is a critical human communication, which unquestionably involves a high level of happiness or sadness communication between people contacts. The sentimental feeling varies in significant proportions among different languages across the other regions over the world. The recognition of emotional states is a reasonably new method in the field of machine learning and AI. The paper presents the study and the performance results of a system for emotion taxonomy. The emotion can be expressed in ways that can be seen, such as makeover terminologies. The analyses on the Autism spectrum disorder(ASD) recorded voice data set are converted into text data. However, in this research paper, we are interested in detecting emotions from the various textual dataset as well as using semantic data augmentation process to fill a few of the words, sentences, or half-broken words, as the Autism spectrum disorder (ASD) patients lack the social communication skills, as the patient does not very well articulate their communication.
言语情感是人类交流的一种关键,它无疑涉及到人与人之间高水平的快乐或悲伤交流接触。在世界其他地区的不同语言中,感伤的感觉差异很大。在机器学习和人工智能领域,情绪状态的识别是一种相当新的方法。本文介绍了一个情感分类系统的研究和性能结果。这种情绪可以用看得见的方式来表达,比如改头换面的术语。将自闭症谱系障碍(ASD)的录音语音数据集转化为文本数据进行分析。然而,在本研究中,我们感兴趣的是从各种文本数据集中检测情绪,以及使用语义数据增强过程来填充一些单词,句子或半破碎的单词,因为自闭症谱系障碍(ASD)患者缺乏社交沟通技能,因为患者不能很好地表达他们的沟通。

A Pragmatic Glaucoma Detection Based On Deep Neural Network Strategy 基于深度神经网络策略的实用青光眼检测
M. S. Eswari, S. Balamurali
Glaucoma is a group of diseases in which the nerve linking the eyes to the brain becomes destroyed, typically as a result of excessive intraocular pressure. The much more prevalent type of glaucoma diseases frequently manifests itself through gradual eyesight impairment. This kind of visual loss due to glaucoma is called open angle glaucoma and although this kind of angular glaucoma is uncommon, it is a clinical crisis with some indications such as eye pain and anxiety as well as acute vision disruption. In this paper, a new deep learning mechanism is used to identify the glaucoma disease in an intense manner, which is called Deep Neural Classification Network (DNCN). This proposed approach identifies the glaucoma disease efficiently by analyzing the retinal images with respect to two form factors such as Optical Coherence Tomography (OCT) and Retinal Fundus Images. The proposed DNCN model processes the retinal image based on the different processing procedures such as pre-processing, feature extraction, filtration and classification, in which it assures the accuracy ratio of 97.3% in outcome with the error rate of 0.27%.
青光眼是一组疾病,其中连接眼睛和大脑的神经被破坏,通常是由于眼压过高。更为普遍的青光眼疾病通常表现为逐渐的视力损害。这种由青光眼引起的视力丧失被称为开角型青光眼,虽然这种角型青光眼并不常见,但它是一种临床危象,有一些症状,如眼睛疼痛和焦虑,以及急性视力障碍。本文提出了一种新的深度学习机制,即深度神经分类网络(deep Neural Classification Network, DNCN),用于青光眼疾病的深度识别。该方法通过对光学相干断层扫描(OCT)和视网膜眼底图像两种形式因素的分析,有效地识别青光眼疾病。提出的DNCN模型基于预处理、特征提取、滤波和分类等不同的处理过程对视网膜图像进行处理,保证了结果的正确率为97.3%,错误率为0.27%。
