M. Namdari, Seung-Hoe Choi
In this paper we introduce an interval regression model, having interval coefficients and crisp input data, and propose a L(p,q)-estimator for the interval coefficients. The L(p,q)-estimator uses one Lp-norm to estimate the left end point of the interval coefficients and independently another Lq-norm for the width of the intervals. An example is presented showing how the results of the regression model vary as we change p and q which implies we need to find the “best" p and q. An error measure is defined and we use response surface methodology to search for the optimal values for p and q to minimize this error.
本文引入了一种具有区间系数和清晰输入数据的区间回归模型,并给出了区间系数的L(p,q)估计量。L(p,q)-估计量使用一个lq -范数来估计区间系数的左端点,并独立地使用另一个lq -范数来估计区间的宽度。给出了一个例子,显示了随着p和q的变化,回归模型的结果是如何变化的,这意味着我们需要找到“最佳”p和q。定义了一个误差测量,我们使用响应面方法来搜索p和q的最优值,以最小化该误差。

Modern CAD technique to design Gyrocompass for UAVs and robot, ships, Aircrafts navigation systems 现代CAD技术设计的陀螺罗盘为无人机和机器人,船舶,飞机导航系统
Q4 Computer Science Pub Date : 2014-02-01 DOI: 10.14355/IJCSA.2014.0301.13

This paper concerns the practical design and implementation of gyrocompass required for operation of all installed navigation equipments on robot, aircrafts, ships, also for UAVs. Most navigation systems today use some type of compass to determine heading direction. Using the Earth Os magnetic field, electronic compasses based on magneto-resistive (MR) sensors can electrically resolve better than 0.1 degree rotation and accuracy from 1 to 2 degree. Most of installed equipment on aircrafts, ships, and spaceship are form of computer-based navigation information system that complies with International regulations. These equipments can be Global position System (GPS), Radar, speed, direction, electronic chart display, height finder for aircrafts and spaceship, echo sounder for ships etc. In our design, Compass Module was utilized with Honeywell's HMC5883L 3-Axis Magnetometer, I2C, 2.7-6.5V, TTL-USB and microcontroller 16F877. For programming of the microcontroller, software PIC Basic pro was used, a window based Software. We are trying to use a cheap and good resolution within a small size Using Anisotropic Magneto resistive (AMR) technology that provides advantages over other magnetic sensor technologies. These anisotropic, directional sensors feature precision in-axis sensitivity and linearity. These sensors’ solid-state construction with very low cross-axis sensitivity is designed to measure both the direction and the magnitude of Earth’s magnetic fields, from milli-gauss to 8 gauss. The complete designed system has three outputs, the first one is USB port friendly user interface, the other two outputs are control logic state outputs. We used the designed gyro output to interface with Radar display so the targets direction can be measured in true mode instead of relative mode; as well, our designed module was employed in car protection in driver safety.
本文研究了机器人、飞机、船舶以及无人机上安装的所有导航设备所需的陀螺罗盘的实际设计与实现。今天大多数导航系统使用某种类型的指南针来确定航向。利用地球磁场,基于磁阻(MR)传感器的电子罗盘可以电分辨优于0.1度的旋转,精度在1到2度之间。飞机、船舶和宇宙飞船上安装的大部分设备都是符合国际规则的计算机导航信息系统。这些设备可以是全球定位系统(GPS),雷达,速度,方向,电子海图显示,飞机和宇宙飞船的测高仪,船舶的回声测深仪等。Compass Module采用Honeywell的HMC5883L三轴磁强计,I2C, 2.7-6.5V, TTL-USB,单片机16F877。单片机的编程采用基于窗口的软件PIC Basic pro。我们正在尝试使用各向异性磁阻(AMR)技术在小尺寸内使用廉价和良好的分辨率,该技术比其他磁传感器技术具有优势。这些各向异性定向传感器具有高精度的轴内灵敏度和线性度。这些传感器的固态结构具有非常低的交叉轴灵敏度,旨在测量地球磁场的方向和大小,从毫高斯到8高斯。完整设计的系统有三个输出,一个是USB接口友好的用户界面,另外两个是控制逻辑状态输出。利用设计好的陀螺输出与雷达显示器接口,实现了以真实模式代替相对模式测量目标方向;并将所设计的模块应用于驾驶员安全的汽车保护中。

Yibin Song, Z. Du
As an efficient method on the fitting or approximating for complex signals, the Radial Base Function Neural Network (RBF‐NN) is widely used in signal modeling. During the training process, the spread coefficient (Sc) is one of important parameters in the RBF‐NN learning algorithm. A suitable Sc can speed up the signal fitting process. This paper presents an improved RBF‐NN learning method based on the adaptive spread coefficient for the signal approximation of complex systems. The improved algorithm is applied to the learning and approximating process of the nonlinear signal. The simulations showed that the presented RBF‐NN has good effects on speeding up the training and approaching process. Meanwhile, the learning convergence of the improved algorithm is more excellent than that of normal algorithm.

Route planning services provide directional functionalities allowing people to make transport plan in which such services are now closely interrelated to people’s daily life. Existing route planners such as digital maps only offer the path search services originated from one place which cannot fulfil the increasing needs of people. In this paper, we first describe a new service for digital map that provides route plans for people from different origins towards the same destination for the purpose of group travelling. Since the performance of route planner highly depends on shortest path search algorithms, in this paper, we also introduce our newly proposed path search algorithm, namely, Multi-origins Common Destination algorithm. The initial evaluation results show it outperforms the counterparts.

It is a specific form of computer-based information system that complies with International safety regulations and can be used in any types of cars, ships, trains, and airplanes. Nationwide in the US in 2005, there were an estimated 1.2 million motor vehicle thefts, or approximately 416.7 motor vehicles stolen for every 100,000 inhabitants.[1] It can be added to navigation, control system for the protected vehicles. Not all protection systems are used for safety and protection but in our design we comply with both requirements. The system can control and displays information of controlled parameters like power for the fuel pump, electricity for the ignition system, audio and visual alarms or others. The designed system can prevent the operation of the engine unless the right store cod is entered also it can let the engine operate only for certain specific previously determined time, or reduce the speed of the engine at certain conditions or it can stop the engine completely in case of danger for example if the driver fell into sleep depend on PIR (Passive Infrared Piezoelectric) or IR motion sensors. It may also display additional navigation-related information, such as Sailing Directions, speed, or remains fuel. The system are power by 12 V dc supply which is available in types of vehicles, to start operation we need to enter the password for the key board, We will demonstrate the program which will is used in actual work for the system it is written in basic to the microcontroller type16F84A .We preferred to design the software using software PIC Basic for microcontroller. This Program is a window based Software and friendly user. Our design covers various methods of prevention to reduce the likelihood of a vehicle getting stolen. These include physical barriers, which make the effort of stealing the vehicle more difficult. Some of these include: Immobilizers, allowing the vehicle to start only if the right password containing the correct code is present in the stored microcontroller to give start signal for ignition. Adding to those Chances of theft can also be reduced with various deterrents, which give the impression to the thief that s/he is more likely to get caught if the vehicle is stolen. These include: Car alarm systems that are triggered if a breaking and entry into the vehicle occurs and trying to start the engine, Killswitch circuits we designed to frustrate or slow down the efforts of a determined car thief. Kill switches are often located between crucial parts of the starting system, between the battery source and the coil, or the fuel pump. A car cannot start without first flipping these killswitches to closed position. Car owners hide these killswitches in obscured areas, under the dashboard, beneath the seat, behind a chair, etc.
本文是一种汽车防盗电子防护系统的实际设计与实现。它是一种特殊形式的基于计算机的信息系统,符合国际安全规定,可用于任何类型的汽车、船舶、火车和飞机。2005年,在美国全国范围内,估计有120万起机动车盗窃案,即每10万居民中约有416.7辆机动车被盗。[1]它可以添加到被保护车辆的导航、控制系统中。并非所有的保护系统都用于安全和保护,但在我们的设计中,我们符合这两个要求。该系统可以控制和显示被控参数的信息,如燃油泵的功率、点火系统的电力、声光报警等。设计的系统可以防止发动机的操作,除非正确的存储cod进入,它可以让发动机只运行特定的事先确定的时间,或降低发动机的速度在某些条件下,或者它可以完全停止发动机在危险的情况下,例如,如果司机陷入睡眠依赖于PIR(被动红外压电)或红外运动传感器。它还可能显示其他与导航相关的信息,如航行方向、速度或剩余燃料。该系统由12v直流电源供电,该电源可在各种类型的车辆中使用,要开始操作,我们需要输入键盘密码,我们将演示将在实际工作中使用的程序,它是用basic编写到单片机类型16f84a上的,我们倾向于使用单片机软件PIC basic来设计软件。这个程序是一个基于窗口的软件和友好的用户。我们的设计涵盖了各种预防方法,以减少车辆被盗的可能性。其中包括物理障碍,这使得窃取车辆的努力更加困难。其中包括:锁止装置,允许车辆只有在存储的微控制器中存在包含正确代码的正确密码时才能启动,以发出点火启动信号。此外,偷窃的机会也可以通过各种威慑措施来减少,这些威慑措施给小偷留下的印象是,如果车辆被盗,他/她更有可能被抓住。其中包括:汽车报警系统,当有人闯入汽车并试图启动发动机时,会触发报警系统;Killswitch电路,我们设计的目的是挫败或减缓一个顽固的偷车贼的行动。关闭开关通常位于启动系统的关键部分之间,在电池源和线圈之间,或燃油泵之间。如果不先把刹车开关扳到闭合位置,汽车是无法启动的。车主把这些开关藏在不显眼的地方,比如仪表盘下面、座位下面、椅子后面等等。
