Intelligent Gesture Recognition to Design more Efficient & Intelligent Multimodal System 智能手势识别提高设计效率智能多式联运系统
S. Chhabria, R. Dharaskar, V. Thakare
Technologies used in multimodal interfaces include conventional direct-manipulation devices like the keyboard, mouse, and pen and touch screen, as well as progressively more advanced recognition technologies such as speech recognition, 2D and 3D gesture recognition, and lip movement and gaze tracking. Usability studies, exploring and evaluating the human factors involved in multimodal input, provide useful insight and guidance toward the design and implementation of multimodal interfaces. The primary goal in the design of any user interface is to facilitate the interaction between user and machine. This user-centered goal is the guiding force behind choices made in the design process. There are, of course, many system engineering issues that influence interface design decisions such as schedules, proper functionality, reliability, etc. However, addressing these issues ideally serves the purpose of creating a better user experience with the system. One purpose of researching multimodal interfaces from an HCI perspective is to evaluate how to take advantage of the benefits they provide over unimodal recognition-based interfaces and conventional keyboard and mouse interfaces. Such advantages include flexibility, availability, adaptability, efficiency, lower error rate, and a more intuitive and natural interaction [1, 2]. Technology is one way to remove the hindrances and benefit the people. It is found that all the recent techniques for Multimodal System are based on computer tools, techniques and technologies like: Artificial Intelligence; Expert System; Graph Matching; Soft Computing; Natural Language Processing (NLP); Multi-Modal and HCI. Several researchers have explored their possibilities and have achieved results to certain extent, but progress in Speech Recognition & Language Understanding using gestures, & optimization as a whole has been limited which gives us future scope to go ahead in this domain.
多模态界面中使用的技术包括传统的直接操作设备,如键盘、鼠标、笔和触摸屏,以及越来越先进的识别技术,如语音识别、2D和3D手势识别、嘴唇运动和凝视跟踪。可用性研究,探索和评估涉及多模态输入的人为因素,为多模态界面的设计和实现提供有用的见解和指导。任何用户界面设计的主要目标都是促进用户和机器之间的交互。这种以用户为中心的目标是设计过程中做出选择的指导力量。当然,有许多系统工程问题会影响接口设计决策,如进度、适当的功能、可靠性等。然而,理想地解决这些问题有助于为系统创建更好的用户体验。从人机交互的角度研究多模态接口的一个目的是评估如何利用它们提供的优于基于单模态识别的接口和传统的键盘和鼠标接口的优势。这些优势包括灵活性、可用性、适应性、效率、更低的错误率以及更直观和自然的交互[1,2]。技术是消除障碍、造福人民的一种方式。研究发现,最近的多式联运系统技术都是基于计算机工具、技术和技术,如:人工智能;专家系统;图像匹配;软计算;自然语言处理;多模式和HCI。一些研究人员已经探索了它们的可能性,并在一定程度上取得了成果,但在使用手势的语音识别和语言理解以及整体优化方面的进展有限,这给了我们未来在这一领域继续前进的空间。

Intelligent Classroom System for Qualitative Analysis of Students' Conceptual Understanding 学生概念理解定性分析的智能课堂系统
Jannat Talwar, Shree Ranjani, Anwaya Aras, Dr Mangesh Bedekar
With the increase of ubiquitous data all over the internet, intelligent classroom systems that integrate traditional learning techniques with modern e-learning tools have become quite popular and necessary today. Although a substantial amount of work has been done in the field of e-learning, specifically in automation of objective question and answer evaluation, personalized learning, adaptive evaluation systems, the field of qualitative analysis of a student's subjective paragraph answers remains unexplored to a large extent. The traditional board, chalk, talk based classroom scenario involves a teacher setting question papers based on the concepts taught, checks the answers written by students manually and thus evaluates the students' performance. However, setting question papers remains a time consuming process with the teacher having to bother about question quality, level of difficulty and redundancy. In addition the process of manually correcting students' answers is a cumbersome and tedious task. In this paper, we put forth the design, analysis and implementation details along with some preliminary results to build a system that integrates all the above mentioned tasks with minimal teacher involvement that not only automates the traditional classroom scenario but also overcomes its inherent shortcomings and fallacies.
随着互联网上无处不在的数据的增加,将传统学习技术与现代电子学习工具相结合的智能课堂系统在今天变得非常流行和必要。尽管在电子学习领域已经做了大量的工作,特别是在客观问答评估的自动化、个性化学习、自适应评估系统方面,但在很大程度上,学生主观段落答案的定性分析领域仍未得到探索。传统的黑板、粉笔、谈话式的课堂场景是,教师根据所教授的概念设置试卷,检查学生手工写的答案,从而评估学生的表现。然而,出题仍然是一个耗时的过程,老师不得不为问题的质量、难度和冗余程度而烦恼。此外,手动批改学生答案的过程是一项繁琐而乏味的任务。在本文中,我们提出了设计、分析和实现细节以及一些初步结果,以构建一个系统,该系统集成了上述所有任务,教师参与最少,不仅实现了传统课堂场景的自动化,而且克服了其固有的缺点和谬误。

Shamla Mantri, Pankaj Agrawal, S. Dorle, Dipti D. Patil, V. Wadhai
Depression is a most common severe mental disturbance health disorder causing high societal costs. In clinical practice rating for depression depends almost on self questionnaires and clinical patient history report opinion. In recent years, the awareness has generated for automatic detection of depression from the speech signal. Some queries are raised that which features are more responsible for depression from speech and which classifiers gives good results. By identifying proper features from speech signal system even one can save the life of a patient. In this paper, a survey of speech signal features which relates for depression analysis is presented. Specially focused on adolescence speech. After surveying it is hypothesized that many speech features are there which are responsible for depression like linear features Prosodic, cepstral, spectral and glottal features and non-linear feature Teager energy operator (TEO). Some classification methods for depression analysis from previous studies are summarized.
抑郁症是一种最常见的严重精神障碍,造成了高昂的社会成本。在临床实践中,抑郁症的评定主要依赖于自我调查问卷和临床病史报告意见。近年来,从语音信号中自动检测抑郁症的意识已经产生。提出了一些问题,哪些特征更应该对语音的抑制负责,哪些分类器给出了良好的结果。通过从语音信号系统中识别出正确的特征,甚至可以挽救病人的生命。本文对语音信号的特征进行了综述,这些特征与抑制性分析有关。特别关注青少年的语言。经过调查,假设有许多语音特征是导致抑郁的原因,如线性特征、韵律特征、倒谱特征、频谱特征和声门特征以及非线性特征Teager能量算子(TEO)。综述了以往研究中抑郁症的分类方法。

Network Performance Evaluation of Jumbo Frames on a Network 网络中巨帧的网络性能评估
S. Narayan, Paula Raymond Lutui
Enhancing network performance has been studied by a number of researchers. The need to provide greater throughput on network infrastructure has been the key driver for these studies. The use of jumbo frames is considered one of the methodologies that can be employed to increase data throughput on networks. It can carry data payloads ranging from 1500Bytes to 9000Bytes which can be supported by Gigabit network hardware. In this research undertaking, a test-bed network is implemented on which jumbo frames are configured on two commonly used operating systems. Performance related metrics like throughput, jitter, delay and drop rates are empirically measured for both IPv4 and IPv6 implementations. The results obtained in this empirical study show that performance metrics values are different in various scenarios.

Dr.Sonali Nimbhorkar(Ridhorkar), L. Malik
Wireless technology has become more persistent with wide demand of mobile devices such as personal digital assistance, smart phones and laptops. The elliptic curve cryptography(ECC) techniques provide greater security using fewer bits resulting in a protocol which requires low computational and communication overhead, therefore suitable for wireless communication system as well as wireless communication devices smart cards, PDAs and other handheld devices. These systems are prone to eavesdropping due to easy access to free space medium. In such cases, appropriate authenticity and cryptographic procedures need to be adopted for reliable and secure communication. Key agreement protocol based on elliptic curve cryptography suited for wireless network. This paper describes various schemes used for implementation of authenticated key agreement protocol in wireless network.

A Novel Genetic Algorithm Approach to Achieve Steady State Power Flow Solution 一种新的遗传算法求解稳态潮流
Shilpa S. Shrawane Kapse, M. Diagavane, N. Bawane
Power flow is nothing but the flow of active and reactive power. To achieve the steady state operating condition of a power system, power flow analysis (PFA) is used. In short, it is to find the approximate values of P, Q, V and δ at various buses, lines flows, generators and loads under steady state condition. Heuristic methods are generally referred as experience based techniques for solving problem, learning and discovery. Heuristics are simple and efficient rules coded by evolutionary processes. In this paper, GA, genetic algorithm, one of such heuristic algorithms have been used to do the power flow analysis in a simple three bus system.
潮流就是有功功率和无功功率的流动。为了实现电力系统的稳态运行状态,需要使用潮流分析(PFA)。简而言之,就是求出各种母线、线路流、发电机和负载在稳态条件下的P、Q、V和δ的近似值。启发式方法通常指的是基于经验的解决问题、学习和发现的技术。启发式是由进化过程编码的简单而有效的规则。本文采用启发式算法中的遗传算法对一个简单的三母线系统进行潮流分析。

Computer Independent USB to USB Data Transfer Bridge 计算机独立的USB到USB数据传输桥
T. Sawant, Bhagya Parekh, Naineel Shah
In this modern era data is omnipresent, be it for business, medicine, entertainment or even education. Thus even the need for data sharing is at its pinnacle. It is even more vital to make sure that data is transferred at high speeds. If the data transfer is faster and safer it will revolutionize the way we live and work. The USB to USB Bridge concept will make it viable to carry out mass data transfer anywhere, anytime which will be secure and will be at high speeds. It consists of just four connecting wires between the device and the Host (Computer), regulated by a set of protocols. The aim of this project is to achieve computer independent data transfer, from one USB flash drive to another. Being portable and battery operated is an added advantage of this system. It is an embedded solution to a practical problem. Also, we can send the data over the internet by connecting our USB Bridge to the internet.
在这个现代时代,数据无处不在,无论是商业、医疗、娱乐,甚至是教育。因此,即使是对数据共享的需求也达到了顶峰。更重要的是确保数据以高速传输。如果数据传输更快、更安全,它将彻底改变我们的生活和工作方式。USB到USB桥的概念将使它能够随时随地进行大量数据传输,这将是安全的,并且将以高速进行。它由设备和主机(计算机)之间的四根连接线组成,由一组协议控制。这个项目的目的是实现计算机独立的数据传输,从一个USB闪存驱动器到另一个。便携和电池供电是该系统的另一个优点。它是一个实际问题的嵌入式解决方案。此外,我们可以通过连接我们的USB桥到互联网上发送数据。

Thus even the need for data sharing is at its pinnacle. It is even more vital to make sure that data is transferred at high speeds. If the data transfer is faster and safer it will revolutionize the way we live and work. The USB to USB Bridge concept will make it viable to carry out mass data transfer anywhere, anytime which will be secure and will be at high speeds. It consists of just four connecting wires between the device and the Host (Computer), regulated by a set of protocols. The aim of this project is to achieve computer independent data transfer, from one USB flash drive to another. Being portable and battery operated is an added advantage of this system.
