WinCC Flexible is used to create screens. The control system control several types of self-running process as voyage data recorder, GPS, hull opening, hull stress, Radar, ship speed, tank fuel level, fuel and machinery temperature, wind speed and direction. Communication, fire doors control station, each type is dictated to specific task. The alarm system is connected to sensors everywhere in the ship and continuously monitors them, if any sensor reading is outside the preset limits we get an alarm. The monitoring system can record any alarm status and save it in hard disk or printer with time stamp. The alarm system depends mainly on data coming from different sensors connected to corresponding measuring points, also an inhibit control can be applied to certain alarm group for disable at certain conditions for the system.","PeriodicalId":39465,"journal":{"name":"International Journal of Computer Science and Applications","volume":"11 1","pages":"6"},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88688845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":39465,"journal":{"name":"International Journal of Computer Science and Applications","volume":"2 1","pages":"55"},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81263316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.

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.","PeriodicalId":39465,"journal":{"name":"International Journal of Computer Science and Applications","volume":"34 1","pages":"1"},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84125038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
