The availability of web and search engines has made the search easier nowadays. Information overload is one of the major problems which require algorithms and tools for faster access. Electronic documents are one of the major sources of information for business and academic information. In order to fully utilizing these on-line documents effectively, it is crucial to be able to extract the summary of these documents. Summarization system will be one of the solutions to the above problem. This project proposes a summarizer system which will be able to perform summarization of multiple documents. The input text documents are analyzed through a parser which parses the input documents and generates parse tree for each sentence. RDF triples are extracted from each sentence by analyzing the typed dependencies generated from the parser in the form of subject, verb and object. Semantic distance is computed between each pair of sentences and a matrix containing the semantic distance for sentences are computed. The measure adopted to compute semantic distance is Wu and Palmer distance. A clustering algorithm is applied to the extracted subject, verb and object space and the extracted RDF triples are grouped into clusters. The important sentences are selected for final summary are extracted using sentence selection algorithm.

Improving the quality of life for the elderly and disabled people and giving them the proper care at the right time is one the most important roles that are to be performed by us being a responsible member of the society. It's not easy for the disabled and elderly people to maneuver a mechanical wheelchair, which many of them normally use for locomotion. Hence there is a need for designing a wheelchair that is intelligent and provides easy maneuverability. In this context, an attempt has been made to propose a thought controlled wheelchair, which uses the captured signals from the brain and eyes and processes it to control the wheelchair. Electroencephalography (EEG) technique deploys an electrode cap that is placed on the user's scalp for the acquisition of the EEG signals which are captured and translated into movement commands by the arduino microcontroller which in turn move the wheelchair.
提高老年人和残疾人的生活质量,在适当的时候给予他们适当的照顾,是我们作为一个负责任的社会成员应该履行的最重要的角色之一。对于残疾人和老年人来说,操纵机械轮椅并不容易,他们中的许多人通常使用它来移动。因此,需要设计一种智能且易于操作的轮椅。在这种情况下,有人尝试提出一种思想控制轮椅,它使用从大脑和眼睛捕获的信号并对其进行处理来控制轮椅。脑电图(EEG)技术部署了一个电极帽,放置在用户的头皮上,用于采集脑电图信号,这些信号被arduino微控制器捕获并转换成运动命令,从而移动轮椅。

Super resolution techniques for medical image processing 医学图像处理的超分辨率技术
Pub Date : 2015-02-01 DOI: 10.1109/ICTSD.2015.7095900

Images with high resolution are desirable in many applications such as medical imaging, video surveillance, astronomy etc. In medical imaging, images are obtained for medical investigative purposes and for providing information about the anatomy, the physiologic and metabolic activities of the volume below the skin. Medical imaging is an important diagnosis instrument to determine the presence of certain diseases. Therefore increasing the image resolution should significantly improve the diagnosis ability for corrective treatment. Furthermore, a better resolution may substantially improve automatic detection and image segmentation results. The arrival of digital medical imaging technologies such as Computerized Tomography (CT), Positron Emission Tomography (PET), Magnetic Resonance Imaging (MRI) etc. has revolutionized modern medicine. Despite the advances in acquisition technology and the performance of optimized reconstruction algorithms over the two last decades, it is not easy to obtain an image at a desired resolution due to imaging environments, the limitations of physical imaging systems as well as quality-limiting factors such as Noise and Blur. A solution to this problem is the use of Super Resolution (SR) techniques which can be used for processing of such images. Various methods have been described over the years to generate and form algorithms which can be used for building on this concept of Super resolution. This paper details few of the types of medical imaginary, various techniques used to perform super resolution and the current trends which are being followed for the implementation of this concept.
高分辨率的图像在医学成像、视频监控、天文学等许多应用中都是需要的。在医学成像中,获得图像是为了医学调查目的,并提供有关皮肤以下体积的解剖、生理和代谢活动的信息。医学影像是确定某些疾病是否存在的重要诊断手段。因此,提高图像分辨率应能显著提高对矫正治疗的诊断能力。此外,更好的分辨率可以大大改善自动检测和图像分割结果。计算机断层扫描(CT)、正电子发射断层扫描(PET)、磁共振成像(MRI)等数字医学成像技术的到来使现代医学发生了革命性的变化。尽管在过去的二十年中,采集技术和优化重建算法的性能取得了进步,但由于成像环境,物理成像系统的局限性以及噪声和模糊等质量限制因素,获得所需分辨率的图像并不容易。这个问题的解决方案是使用超分辨率(SR)技术,可以用来处理这样的图像。多年来,已经描述了各种方法来生成和形成可用于构建超分辨率概念的算法。本文详细介绍了几种医学想象的类型,用于执行超分辨率的各种技术以及为实现这一概念而遵循的当前趋势。

With the advent of smart phones, mobile phones underwent metamorphosis and became the mother of all inventions. Transforming into devices capable of handling high end applications, mobile phones have introduced the features of mobility and portability in almost all applications and software that were designed for a personal computer. They also serve as dynamic gateways to the internet through which real time exchange of information and resources can take place. Technology that allows applications to share local resources through a remote service is one of the latest breakthroughs in the world of communication. We aim to develop an environment through which mobile phone users can experience the use of such technology. All smart phones with Android OS incorporate touch screens. Such phones utilize their screens to display and manipulate information conveniently. By making the screen of one mobile user available to other mobile users, the interaction between two mobile users can be taken to a whole new level. This is what we want to achieve through our application.

Energy in various forms has played an increasingly important role in world-wide economic progress and industrialization. Sunlight available freely as a direct and perennial source of energy provides a non-polluting reservoir of fuel. The simplest and the most efficient ways to utilize solar energy are to convert it into thermal energy for heating applications by using solar collectors. The thermal efficiency of solar air heaters in comparison of solar water heaters has been found to be generally poor because of their inherently low heat transfer capability between the absorber plate and air. Various methods to improve heat transfer in thermal system have been developed extensively. The majority of commercially available enhancement techniques are passive ones. The use of artificial roughness on a surface is an effective technique to enhance heat transfer to fluid flowing in ducts. In this research work, a new technique of heat transfer enhancement is proposed, which contains an artificial roughness in the form of multi arc shape ribs with gap on the inner side surface of the absorber plate. The artificial roughness on the absorber plates having three different pitch ratios (15, 20 and 25). The heat transfer enhancement with newly designed artificial roughness is compared with smooth absorber plate. The maximum heat transfer enhancement is observed for the Relative Roughness Pitch (P/e) of 15 and 51% increase in heat transfer with respect to smooth plate on account of increase in friction factor of 40%. It has been observed that the new passive enhancement technique proposed in this work shows substantial increase in heat transfer rate over smooth plate.
各种形式的能源在世界经济发展和工业化进程中发挥着越来越重要的作用。阳光作为一种直接的、永久的能源,是一种无污染的燃料储存库。利用太阳能的最简单和最有效的方法是利用太阳能集热器将其转化为热能用于加热应用。与太阳能热水器相比,太阳能空气加热器的热效率普遍较差,因为它们在吸收板和空气之间的固有传热能力较低。各种改善热系统传热的方法得到了广泛的发展。大多数商业上可用的增强技术都是被动的。在表面上使用人工粗糙度是一种有效的技术,以增强热传递到管道中流动的流体。在本研究中,提出了一种新的强化传热技术,该技术在吸收板的内表面以带间隙的多圆弧肋的形式存在人工粗糙度。三种不同螺距比(15,20和25)的吸收板上的人工粗糙度。将新设计的人工粗糙度与光滑吸收板的强化传热效果进行了比较。当相对粗糙节距(P/e)为15时,由于摩擦系数增加了40%,传热效果比光滑板提高了51%。研究发现,本文提出的新型被动强化技术在光滑板上的换热率有明显提高。

Phishing is an activity that is carried out online inorder to steal the identity of the users online such as their user IDs, passwords and credit card details. Unaware online users easily fall for these phishing web pages because of their high similarities to the real ones. Detecting & Identifying fake websites is a very cumbersome task. Several attributes are needed to be taken into consideration. The existing phishing detection systems are time consuming & heavily rely on the backend database available. In this proposed system, main focus is on retrieving the necessary attributes in real time using Hadoop-MapReduce, which will help us increase both speed & throughput of the system. This new system aims at providing secure browsing experience to the user.

Helical tubes are universally used in chemical reactors, ocean engineering, heat exchangers, piping system and many other engineering applications. It has been long recognized that heat transfer characteristic of helical tubes are much better than that of straight ones because of the occurrence of secondary fluid flow in planes normal to the main flow inside the helical structure. In the present study an experimental investigation of heat transfer in cone shaped helical coil heat exchanger is reported for various Reynolds number. The purpose of this study is to design and fabricate a non-previously implemented shell and cone shaped helical coil and fitted with a twin cylinder diesel engine to recover waste heat from the exhaust gas to heat water. A “C” program was developed for the easiness of the design and an AutoCAD model of the design was made. For the fabrication of the coil, copper tubes were used. To evaluate the designed value various temperatures have taken for various mass flow rate of the water. The results show that the design value are having a good agreement with the experimentally obtained value. It was found that the heat transfer rates are 1.18 to 1.38 times more for the cone shaped helical coil than that of simple helical coil.
螺旋管广泛应用于化学反应器、海洋工程、热交换器、管道系统和许多其他工程应用中。人们早就认识到螺旋管的传热特性比直管好得多,这是由于螺旋结构内部在与主流垂直的平面上存在二次流体流动。本文对锥形螺旋盘管换热器在不同雷诺数下的换热特性进行了实验研究。本研究的目的是设计和制造一个以前没有实现的壳锥形螺旋线圈,并安装一个双缸柴油机,以回收废气中的余热来加热水。为方便设计,开发了C语言程序,并制作了AutoCAD模型。为了制造线圈,使用了铜管。为了计算设计值,对不同的水质量流量取了不同的温度。结果表明,设计值与实验值吻合较好。结果表明,锥形螺旋盘管的换热率是普通螺旋盘管的1.18 ~ 1.38倍。

It has been long recognized that heat transfer characteristic of helical tubes are much better than that of straight ones because of the occurrence of secondary fluid flow in planes normal to the main flow inside the helical structure. In the present study an experimental investigation of heat transfer in cone shaped helical coil heat exchanger is reported for various Reynolds number. The purpose of this study is to design and fabricate a non-previously implemented shell and cone shaped helical coil and fitted with a twin cylinder diesel engine to recover waste heat from the exhaust gas to heat water. A “C” program was developed for the easiness of the design and an AutoCAD model of the design was made. For the fabrication of the coil, copper tubes were used. To evaluate the designed value various temperatures have taken for various mass flow rate of the water.

India is a country dominated by villages. Agriculture is the main occupation in India. Development of any country is dependent on the healthy status of farmers. Farmer is suffering from various problems mainly due to the lack of unity among farmers and no union to support farmers. Technology is not reaching the farmers directly. This paper discusses an innovative solution which proposes the joint effort of Non Government social Organization and Engineers, to help farmers and ease the task of Government and avoid losses occurring due to mismanagement. This idea suggests that, initially a data network has to be created to link each farmer's data of each village to all Talukas, Each Taluk to Districts and to state. This is carried out by software projects using DBMS and VB.Net. Projects are the part of engineering curriculum and societal need based projects help in enhancement of learning. A Non-Government Organization manages to collect the information about each farmer's requirement such as seeds, fertilizers and manures. This information is passed to manufacturers and with the assistance and co-operation of Government and concerned banks, materials will be supplied to NGO who in-turn manages to supply to each village farmers. Similarly, at the harvest time, crop yield estimation of each village is done through the network. This information is provided to large buyers and exporters, through NGO and money transaction is again through NGO to each farmer. It is estimated that by this supply chain management farmer will get his market at his door steps. Precision agriculture information is stored in the database. Farmer can get the timely suggestions and assistance at village level NGO only through the software. Thus we can expect that farmer's life style can be improved by this supply chain management designed through collaborative work of NGO and engineers.
印度是一个以村庄为主的国家。农业是印度的主要职业。任何国家的发展都依赖于农民的健康状况。农民遭受各种问题的主要原因是农民之间缺乏团结,没有工会来支持农民。技术并没有直接惠及农民。本文提出了一个由民间社会组织和工程师共同努力的创新解决方案,以帮助农民,减轻政府的任务,避免因管理不善而造成的损失。这个想法表明,首先必须建立一个数据网络,将每个村庄的每个农民的数据连接到所有的taluka,每个taluka连接到地区和州。这是通过使用DBMS和VB.Net的软件项目来实现的。项目是工程课程的一部分,基于社会需求的项目有助于提高学习。一个非政府组织设法收集每个农民的需求信息,如种子、肥料和粪肥。这些信息将传递给制造商,在政府和有关银行的协助和合作下,将向非政府组织提供材料,由非政府组织负责向每个村庄的农民提供材料。同样,在收获季节,通过网络对每个村庄的作物产量进行估算。这些信息通过非政府组织提供给大买家和出口商,资金交易也通过非政府组织提供给每个农民。据估计,通过这种供应链管理,农民将在家门口获得市场。精准农业信息存储在数据库中。农民只有通过软件才能得到村级非政府组织及时的建议和帮助。因此,我们可以期待通过非政府组织和工程师合作设计的供应链管理可以改善农民的生活方式。
