In this current smart era, electricity is considered a necessity for development as almost all of machinery and circuitry runs on electrical power. Therefore, the production of electricity is a must for attaining progress. But nowadays, there is a constant struggle for access to large fossil reservoirs and the development for renewable resources is slow. There have been innovative inventions such as the wind turbines, water turbines, solar cells and many other renewable sources. These resources have slowed down the depletion of fossil fuels to a certain extent, but these inventions do have their shortcomings and most areas where energy harnessing is possible, are left unanswered. One such area where energy conversion is possible is in the water transportation system. To harness electrical energy from this system, a small turbine generator can be installed onto the pipelines to harness the kinetic energy of the flowing water in them. Hence forth by applying this research, another renewable energy resource is developed.
在当前的智能时代,电力被认为是发展的必需品,因为几乎所有的机械和电路都依靠电力运行。因此,电力生产是实现进步的必要条件。但如今,人们一直在为获得大型化石水库而斗争,可再生资源的开发也很缓慢。有一些创新发明,如风力涡轮机、水轮机、太阳能电池和许多其他可再生能源。这些资源在一定程度上减缓了化石燃料的消耗,但这些发明确实有其缺点,而且大多数可以利用能源的领域都没有得到解决。其中一个可能进行能量转换的领域是在水运系统中。为了利用该系统的电能,可以在管道上安装一台小型涡轮发电机,以利用管道中流动水的动能。因此,通过应用这一研究,开发了另一种可再生能源。

This paper facilitates radiologists in diagnosis of lung tumor and provides with a probability to differentiate between the types of tumor through automated analysis and increase in accuracy. The system is aggregated model for tumor identification and 3D reconstruction of lung using (computed Tomography) CT-scan images in Digital Imaging and Communications in Medicine (DICOM) format to identify the lung tumor (Benign or Malignant) using learning algorithm. The proposed system is capable to reconstruct the 3D model of lung tumor using CT-scan medical images and identify tumor (Benign or Malignant) including location of tumor (Attached to wall or parenchyma) with significant accuracy. The proposed diagnostic software provides significant results with bright CT scans to identify lungs tissue with different orientations by rotating it and reduces the enormous false positive rate by increasing the efficiency and accuracy of the diagnostic procedure. Whereas, CT-scan image is below required brightness or if CT-scan is done in a dark room than the module does not shows considerable results of segmentation. The proposed computer aided diagnosis can help the radiologists to detect tumor at early stage, decrease the enormous false positive rate, and the overall cost of the diagnostic procedure; thus, bringing windfall benefits in the field of medical imaging.
本论文为放射科医师对肺肿瘤的诊断提供了便利,并通过自动化分析提供了区分肿瘤类型的可能性,提高了准确性。该系统是用于肿瘤识别和肺部三维重建的聚合模型,使用数字成像和医学通信(DICOM)格式的ct扫描图像,使用学习算法识别肺肿瘤(良性或恶性)。该系统能够利用ct扫描医学图像重建肺肿瘤的三维模型,并以显著的准确性识别肿瘤(良性或恶性),包括肿瘤的位置(附着于壁或实质)。该诊断软件通过旋转明亮的CT扫描来识别不同方向的肺组织,提供了显著的结果,并通过提高诊断程序的效率和准确性来减少巨大的假阳性率。然而,ct扫描图像低于要求的亮度,或者如果ct扫描在暗室中进行,则该模块没有显示出相当大的分割结果。提出的计算机辅助诊断可以帮助放射科医生在早期发现肿瘤,减少巨大的假阳性率,降低诊断过程的总体成本;从而为医学影像领域带来意外的收益。

eGovernance is a vital component of any nations’ modern governmental structure and suitable for mass-scale adaptation. Pakistan has also established an eGovernance council for mitigation of the problems of the common man. One big step in this direction is the establishment of Pakistan Citizens’ Portal (PCP) that facilitates eGovernance. Through the PCP app, citizens can directly lodge complaints and report their issues for immediate resolution. This study looks at the important aspect of mobile usability through field tests to determine the viability of the PCP app in Pakistan. This study is vital towards determining the main factors for large scale adaptation of the PCP app and underlines the weaknesses of the present system. Hence, the PCP app was evaluated in terms of efficiency and effectiveness according to ISO 92421-11. And the user satisfaction was measured through system usability satisfaction (SUS) on five-point Likert scale. The evaluation method included more than a dozen citizens of Sindh and findings showed that overall application enriched the user experience. However, the few areas of PCP were identified as needing improvements. The main areas that the PCP application needs to improve are the areas of registration and ‘findability’ which would further improve user satisfaction and experience.
电子政务是任何国家现代政府结构的重要组成部分,适合大规模适应。巴基斯坦还成立了一个电子政务委员会,以缓解普通人的问题。朝着这个方向迈出的一大步是建立了巴基斯坦公民门户网站(PCP),为电子政务提供便利。通过PCP应用程序,公民可以直接提出投诉并报告他们的问题,以便立即解决。这项研究通过实地测试来确定PCP应用程序在巴基斯坦的可行性,着眼于移动可用性的重要方面。这项研究对于确定PCP应用程序大规模适应的主要因素至关重要,并强调了当前系统的弱点。因此,根据ISO 92421-11对PCP应用程序的效率和有效性进行了评估。用户满意度采用系统可用性满意度(SUS)五点Likert量表进行测量。该评估方法包括十几名信德省公民,结果显示,整体应用丰富了用户体验。然而,PCP的少数几个领域被确定为需要改进。PCP应用程序需要改进的主要领域是注册和“可查找性”,这将进一步提高用户满意度和体验。

Robust and accurate adhesion level identification is crucial for proper operation of railway vehicle. It is necessary for braking and traction forces characterization, development of maintenance strategies, wheel-rail wear predictions and development of robust onboard health monitoring systems. Adhesion being the function of many uncertain parameters is difficult to model, whereas data driven algorithms such as Deep Neural networks (DNNs) are very good at mapping a nonlinear function from cause to effect. In this research a solid axle Wheel-set was modeled along with different adhesion conditions and a dataset was prepared for the training of DNNs in Python. Furthermore, it explored the potential of DNNs and various data driven algorithms on our noisy sequential dataset for classification task and achieved 91% accuracy in identification of adhesion condition with our final model.
可靠准确的粘着水平识别对于铁路车辆的正常运行至关重要。这对于制动和牵引力的表征、维护策略的制定、轮轨磨损预测以及稳健的车载健康监测系统的开发都是必要的。粘附是许多不确定参数的函数,很难建模,而深度神经网络(DNN)等数据驱动算法非常善于将非线性函数从原因映射到结果。在这项研究中,对具有不同附着力条件的实心轴轮对进行了建模,并为Python中DNN的训练准备了数据集。此外,它在我们的噪声序列数据集上探索了DNN和各种数据驱动算法用于分类任务的潜力,并用我们的最终模型在识别粘附条件方面实现了91%的准确率。

Driving is one of the most important job for almost all people. Person use their vehicle to travel from one place to other. The count of automobiles is increasing every day. It increases the risk to accident. Currently, percentage numbers of accident are increasing drastically. One of the main reason for accident is the failure in concentration of the driver due to which he/she may fall asleep or sometimes due to the delay for applying the brake. A new system is developed that can solve these problems where an alert is given to the people present inside the vehicle to indicate that the driver is falling asleep and a cosystem which can automatically stop the vehicle even if the driver may not brake manually due to obstacles. Our aim is to make a smart driving system with automatic waking alert and automatic braking system to ensure the safety of driving.
驾驶几乎是所有人最重要的工作之一。人们用他们的车辆从一个地方旅行到另一个地方。汽车的数量每天都在增加。这增加了发生事故的风险。目前,事故数量的百分比正在急剧增加。事故的主要原因之一是司机注意力不集中,可能会睡着,有时也可能是因为刹车延迟。一种新的系统可以解决这些问题,它会向车内的人发出警报,表明驾驶员正在入睡,并且一个生态系统可以自动停止车辆,即使驾驶员可能由于障碍物而无法手动刹车。我们的目标是做一个具有自动唤醒警报和自动制动系统的智能驾驶系统,以确保驾驶安全。

Magnetic Resonance Imaging (MRI) is a modern, robust method that uses in the detection of various medical problems. In this research work, a trial is used to attempt for the detection of tumour in pancreas MR images. An automated classifier is used for detection of tumour in MR images and avoids the drawbacks of MRI. This automated classifiers can detect automatically, either the MR image is affected or not affected. Features are extracted from MR images using second order statistics approach and are classified by two techniques Support Vector Machine (SVM) and Extreme Learning Machine (ELM). SVM approach has high classification accuracy (96%) which is higher than ELM, while ELM performs faster compared to SVM.

At present, Frequent Biometrics Scientific Research deals with other biometric application like Face, Iris, Voice, Hand-Based Biometrics traits for classification and spotting out the persons. These Specific Biometric traits have their own improvement and weakness for opting the terms like Accuracy & cost of all applications. However, in addition to other Face-based Biometric techniques, Ear Recognition has been appealed to Boom the attention among other Biometric researchers. This Image Template Pattern Formation of Ear cuddles the report which is relevant for maculating the Uniqueness of their individuality. This Ear Biometric trait observes the person’s identity based on its stable Anatomical behavior. This biometric trait does not involve any emotional feelings with facial expressions in the same way as a unique pair of Fingerprint. In this work, a Contemporary approach for Personal identification is imported with Ear along with the data stores in a secured way has been proposed. This authentication Process includes the revolution of features with Gabor Filter and Dimension Reduction based on Multi-Manifold Discriminant Analysis (MMDA). This work is adequately analyzed in Matlab with the Evaluation metrics such as FMR, GAR, FNMR, by modifying the key value each time. The results of this suggested work promote better values in recognition of individuals as for Ear modalities. Conclusively the Features are grouped using K-Means for both identification and Verification Process. This Proposed system is initialized with Ear Recognition Template based on Fuzzy Vault. The Key stored in the Fuzzy Vault is utilized in safeguarding the existence of Chaff Points.
目前,频繁生物识别科学研究涉及其他生物识别应用,如人脸、虹膜、语音、基于手的生物识别特征,用于分类和识别人员。这些特定的生物特征在选择所有应用程序的准确性和成本等术语时有其自身的改进和弱点。然而,除了其他基于人脸的生物识别技术外,耳朵识别也受到了其他生物识别研究人员的关注。这种图像模板模式形成的耳朵拥抱报告,这是有关斑点的独特性,他们的个性。这种耳朵生物识别特征基于其稳定的解剖行为来观察人的身份。这种生物特征不会像一对独特的指纹那样,通过面部表情产生任何情感。在这项工作中,提出了一种现代的个人身份识别方法,该方法与Ear一起以安全的方式导入数据存储。该认证过程包括基于Gabor滤波器的特征革命和基于多流形判别分析的降维。通过每次修改关键值,在Matlab中使用FMR、GAR、FNMR等评估指标对这项工作进行了充分的分析。这项工作的结果表明,在识别个体方面,耳朵模式有更好的价值。最后,使用K-Means对特征进行分组,用于识别和验证过程。该系统采用基于模糊库的耳朵识别模板进行初始化。存储在模糊库中的密钥用于保护Chaff点的存在。

Automated mechanization for curing a disease is a reliable and protuberant method. A disease in brain can be detected by Magnetic Resonance Imaging (MRI). In this context, image fusion is a method for creating an image by merging pertinent data from 2 or more images. The resultant image will be highly useful than the individual input images to retentive the vital characteristics of every image. Multiple image fusion is a significant method employed in image processing techniques.

自动化机械化治疗疾病是一种可靠且突出的方法。大脑中的疾病可以通过核磁共振成像(MRI)来检测。在这种情况下,图像融合是一种通过合并来自2个或多个图像的相关数据来创建图像的方法。所得到的图像将比单独的输入图像更有用,以保持每个图像的重要特征。多图像融合是图像处理技术中的一种重要方法。在本研究中,对MRI和计算机断层扫描(CT)图像进行了基于差分进化(DE)算法的图像融合。已经进行了仿真工作来评估DE在图像融合上的不同质量测量。
