Order Sensitive Scoring for Objective Evaluation of Remote Sensing - Image Retrieval System
Get PDFIn order to make the evaluation result become fair and consistent without relying on user judgement, we proposed a new mechanism of objective evaluation for remote sensing image retrieval system. This mechanism is performed by dividing the image database into some subjects and select one subject as a ground truth. Subsequently, we take an image of the ground truth as a query Q. Retrieval accurate ratio (pAR) for query Q will be computed as a comparison between utility value and maximum possible utility. This pAR value can provide the non-degeneracy score. We repeat the retrieval process for all the images in the ground truth as the query and take averaged accurate ratio (pAAR) for a subject as the average value of all the accurate ratio for all queries in a subject. These process is performed for all subjects in the database, thus we can obtain the mean averaged accurate ratio (pmAAR) as mean value of all averaged accurate ratio for all subjects
Dasar Pemodelan dan Navigasi Flocking Mobile Robot dengan Aplikasi Sensor Jarak
Get PDFAbstract—The main concept of flocking mobile robot is one robot leader followed by other robots, this concept was inspired by nature, flocking of birds, swarms of bees etc. This research objective is to investigate the possibility of applying distance sensors modeled as virtual spring-damper in navigating flocking robot within leader-follower robot system. Distance sensors installed at follower robots in order to maintain certain distance to leader robot and by the time leader robot stop so will the follower robots. This research started by modeling the system in virtual spring-damper system, simulating the effectiveness of proposed method in MATLAB/Simulink and finally applying the method in to real mobile robot system. Simulation results shows that follower robots follow leader robot in certain fixed distance and the velocities output of leader robot and follower robots are also the same, meaning that the robots within the system maintain their initial formation; train formation or wedge formation. The simulation results also shows that modeling distance sensor as virtual spring damper is an effective method for navigating the flocking robot system, moreover stable spring-damper system will ensure the system stability. Simulation results successfully applied to real system consist of one leader robot and one follower robot. Index Term—flocking robot, robot leader, robot follower, sensor jarak dan virtual spring-dampe

Analisa serangan password cracking dengan menggunakan tools pwdump v7.1 dan cain and abel
No full textIstilah serangan password cracking atau juga disebut sebagai serangan brute- force merupakan masing-masing proses untuk menebak password. Dalam proses ini perangkat lunak atau tool menciptakan sejumlah besar kombinasi password. Pada dasarnya ini adalah teknik footprinting yang digunakan oleh perangkat lunak untuk memperoleh informasi sandi dari sistem. Pwdump v7.1 merupakan tool untuk mengambil file Security Account Manager (SAM) dari Windows yang kemudian akan dideskripsikan via command prompt. Sedangkan Cain & Abel merupakan tool untuk memecah beberapa kombinasi password yang didapat dari Pwdump. Kombinasi password tersebut selanjutnya akan dicocokan dengan password windows yang kita cracking dengan menggunaka serangan brute-force
