Energy wastage is a serious issue in industries and office buildings. Around 40% of energy is consumed for HVAC systems and 15% of energy is consumed for lighting systems. Lighting is one area where energy can be conserved. But before that there arises a necessity to know the measures and policies and the need for the energy conservation. The main aim of the paper is to give an overall view of the process involved from setting the status, measures and policies to implementing the policies through audits and come out with new methods to achieve energy conservation for lighting systems.

In this paper, a 3D human body meshed model with low resolution is obtained by parametric digital human modeling, but the meshed surface is not smooth enough to meet the requirements of practical application. To achieve the smoothing effect of the geometric model of digital human body, this paper proposes a mesh-smoothing method of 3D human model based on Sqrt3 subdivision algorithm. Experiment shows that this method applies to the multicurvature mesh body model based on parametric modeling method and achieves good results. The method is simple, efficient and of well-reserved feature.

Vehicle detection is to detect vehicles that are being developed to provide traffic counting, vehicle classification. In existing method, vehicles are identified by using channel scale space of Red, Green, Blue (RGB) images, taking license plate as a feature. The union of edge image is taken by combining red region, green region, blue region and grey region. The shape of License Plate (LP) is referred as candidate shape. Based on the edge points there are few issues in the candidate shapes. They are outliers, open shape and fragmentation. The outliers are removed by the removal of outer outlier method which is to remove the unwanted projections in the candidate shapes. In proposed method, color based detection is used along with channel scale space technique. In this color based detection method, CIE-XYZ color model is used. By calculating the aspect ratio, the license plate is detected to identify the vehicles. The accuracy of this method is 94.23%.
车辆检测是对正在开发的车辆进行检测,提供流量统计、车辆分类。现有方法以车牌为特征,利用红、绿、蓝(RGB)图像的通道尺度空间进行车辆识别。利用红色区域、绿色区域、蓝色区域和灰色区域进行边缘图像的合并。车牌(LP)的形状称为候选形状。基于边缘点的候选形状几乎没有问题。它们是异常值,形状开放,碎片化。通过去除外部离群点方法去除离群点,即去除候选形状中不需要的投影。在该方法中,基于颜色的检测与通道尺度空间技术相结合。在这种基于颜色的检测方法中,使用了CIE-XYZ颜色模型。通过计算宽高比,检测车牌以识别车辆。该方法的准确率为94.23%。

The ease of availability of digital data in this digital world has increased their unfair and unjust use which should be tackled with reliable and robust techniques. Digital images can be protected to a large extend with the application of watermarks. A large number of watermarking techniques have been developed during the past few decades and are found to be useful in one or the other way. This paper presents a comparative study between two different digital image watermarking algorithms — one based on Haar DWT and bit-plane slicing and the other is a histogram shape based method where the watermarking is done using an embedded security key. Moreover, the simulation results for the watermarking algorithm based on Haar DWT and bit-plane slicing using Xilinx ISE Design Suite are also used for comparison. Comparison is done mainly on the basis of Peak Signal to Noise Ratio and Mean Signal Error values for the images.
在这个数字世界中,数字数据的容易获得增加了对数字数据的不公平和不公正使用,应该用可靠和有力的技术来解决。应用水印技术可以在很大程度上保护数字图像。在过去的几十年里,大量的水印技术被开发出来,并被发现以一种或另一种方式有用。本文对两种不同的数字图像水印算法进行了比较研究,一种是基于Haar DWT和位平面切片的数字图像水印算法,另一种是基于直方图形状的数字图像水印算法,该算法使用嵌入式安全密钥进行水印。此外,利用Xilinx ISE Design Suite对基于Haar DWT和位平面切片的水印算法进行了仿真比较。主要根据图像的峰值信噪比和平均信号误差值进行比较。

Financial Transmission Right is a financial instrument awarded to bidders in the FTR auctions that entitle the holder to a stream of revenues (or charges) based on hourly day-ahead congestion price differences across the path. The purpose of FTRs is to protect Firm Transmission Service Customers from increased cost due to transmission congestion when their energy deliveries are consistent with their firm reservations. Essentially, FTRs are financial instruments that entitle the holder to rebates of congestion charges (rentals) paid by the Firm Transmission Service Customers. AC-DC OPF based electricity nodal pricing methodology to evaluate FTR in more simple way for a real network of 400/765 kV MSETCL system. Study evaluated FTRs methodology for real power system with reference to several conditions. This study concluded that option and obligation FTR charges are more in peak load conditions compared to off-peak load conditions. It is useful to system operator to study transmission congestion management and market operations. Market participants may also get information about behavior of FTRs at different conditions for better economic decision.
金融传输权是在FTR拍卖中授予竞标者的一种金融工具,它使持有者有权根据每小时穿越路径的拥堵价格差异获得一系列收入(或收费)。ftr的目的是保护公司输电服务客户,使其在能源交付与公司预定量一致的情况下,免受因输电拥塞而增加的成本。从本质上讲,ftr是一种金融工具,持有者有权从公司传输服务客户支付的拥堵费(租金)中获得回扣。400/765 kV MSETCL系统实际电网中基于交直流OPF的电力节点定价方法更简单地评估FTR。本文结合实际电力系统的几种情况,对ftr方法进行了评价。本研究的结论是,在高峰负荷条件下,选择性和义务性FTR费用比非高峰负荷条件下更多。研究输电拥塞管理和市场操作对系统运营商有一定的参考价值。市场参与者还可以获得关于ftr在不同条件下的行为信息,以便做出更好的经济决策。

The aim of automated streetlight management system using IOT is the conservation of energy by reducing electricity wastage as well as to reduce the manpower. Streetlights are the elemental part of any city since it facilitates better night visions, secure roads, and exposure to public areas but it consumes a quite large proportion of electricity. In the manual streetlight system lights its powered from sunset to sunrise with maximum intensity even when there is sufficient light available. This energy wastage can be avoided by switching off lights automatically. The saved energy can be efficiently utilized for other purposes like residential, commercial, transportation etc. This can be achieved using an IOT enabled streetlight management system. The project uses Light Emitting Diodes (LED) that do not consume an enormous amount of electricity to replace the power consuming traditional HID lamps. LED lights along with LDR enables the intensity variation which is infeasible with the HID lamps. As LEDs are directional light sources it can emit light in specific direction thereby optimizing the efficiency of the streetlights. This system includes an additional DHT11 Temperature-Humidity sensor. This provides the exact temperature and humidity of a particular region. DHT11 is a composite sensor that contains a calibrated digital signal output of the temperature and humidity. It ensures high reliability and excellent long-term stability. This work is implemented using a programmed Arduino board for providing the required intensity of light at various times. The proposed work has achieved a better performance compared to the existing system.
使用物联网的自动化路灯管理系统的目的是通过减少电力浪费来节约能源,并减少人力。路灯是任何城市的基本组成部分,因为它促进了更好的夜景,安全的道路,并暴露在公共区域,但它消耗了相当大比例的电力。在手动路灯系统中,即使有足够的光线,它也可以从日落到日出以最大强度供电。这种能源浪费可以通过自动关灯来避免。节约的能源可以有效地用于住宅、商业、交通等其他用途。这可以通过启用物联网的路灯管理系统来实现。该项目使用不消耗大量电力的发光二极管(LED)来取代耗电的传统HID灯。LED灯和LDR灯可以实现强度变化,这是HID灯无法实现的。由于led是定向光源,它可以在特定方向发光,从而优化路灯的效率。该系统包括一个额外的DHT11温湿度传感器。这提供了特定地区的确切温度和湿度。DHT11是一种复合传感器,包含一个校准的温度和湿度的数字信号输出。它保证了高可靠性和优异的长期稳定性。这项工作是使用一个编程的Arduino板来实现的,它可以在不同的时间提供所需的光强度。与现有系统相比,所提出的工作取得了更好的性能。

An operational transconductance-amplifier (OTA) is mainly designed for low voltage and low frequency applications such as for the medical applications. The Operational Transconductance Amplifier (OTA) is the part in an analog integrated circuits for many wireless applications such as binural hearing aids. High gain is becoming more important in miniature devices because this parametric form provide the significant outcomes, so it becomes a challenge to design a low power OTA. The proposed design helps to generates the design parameters such as the Width/Length ratio are given to design specifications, such as, gain, unity gain-bandwidth, phase margin. This paper is mainly proposed for the low frequency application using transconductance amplifier.

Topological Derivative's application in the field of image processing usually involves restoration and segmentation. This paper focussing on techniques of Topological derivative for solving domain related issues and condition for boundary in the domain, besides solving for shape sensitivity. This helps in detecting the changes caused in the diseased organs. Lagrange Multiplier helps us to solve for the maxima problem related to curvature/boundary as founded with the Topological method. This is a step forward because it addresses boundary problems directly by taking into account constraints involved in the problem. Level Set Method further solves the problem as it helps in implicit representation. Besides, it handles changes in topology easily during evolution of the surface. Many dimension problem is also solved with the help of velocity field and normal vector. Updating over a narrow region instead of the whole image is another advantage.

With last two decades, Radio Frequency (RF) Microelectromechanical system (MEMS) switches are becoming more popular in the electronics domain. Since power consumption has become the highest concern in many electronics devices. The main concern in using RF MEMS switches is its high actuation voltage. Thus this paper generally focuses on the analysis and simulation of RF MEMS metal contact switch having an arc-shaped cantilever beam to obtain the low actuation voltage. Simulations are done using the finite element modeling (FEM). Intellisuite 8.7v software has been used to get the results of the switch. The design has been modified according to thickness of the beam and air gap to carry out electrostatic actuation. The pull-in voltage is obtained to be 1.4 V.
近二十年来,射频(RF)微机电系统(MEMS)开关在电子领域越来越受欢迎。由于功耗已成为许多电子设备中最受关注的问题。使用射频MEMS开关的主要问题是其高驱动电压。因此本文主要对采用弧形悬臂梁的射频MEMS金属触点开关进行分析和仿真,以获得较低的驱动电压。采用有限元模型进行了仿真。使用intellisite 8.7v软件对开关结果进行分析。根据梁的厚度和气隙对设计进行了修改,实现了静电驱动。拉入电压为1.4 V。
