In this paper, the importance of odor localization is explained. The researchers that investigated the experiments and applications of odor localization using static sensors, mobile sensors (that were integrated in single robot, multi robot, and swarm robot) are described. However, there are some difficulties faced by the researchers in applying the mobile robots in the real situation, such as: the speed of mobile robots are not as fast as the odor patches transporting and the use of more than one sensor in mobile robot can make noises or errors. In the future, the plume finding in the uncertain environment and the challenges mentioned above will be the authorsâ consideration.

Abstrak : ADVENTURE (ADVanced ENgineering analysis Tools for Ulra large Real world) adalah proyekambisius Jepang yang menggunakan "komputer tercepat di dunia 30-100 TFLOPS pada tahun2002", tapi juga digunakan untuk analisis GeoFEM yang dirancang untuk beroperasi dalamlingkungan komputasi virtual yang sama (Earth Simulator). Beberapa teknologi yang digunakandalam system ini meliputi arsitektur berbasis modul, standarisasi format dan library, pemodelanyang efisien, visualisasi 3-d untuk model 10-100.000.000 derajat kebebasan (DOF) dan dapatdiapaki dalam berbagai lingkungan computer parallel. Salah satu permasalahan yang dapatdiselesaikan dengan ADVENTURE System adalah analasis retakan seperti analsis J-Integralyang memiliki derajat kebebasan besar. Kami telah mengembangkan Post Program untukmenganalisis sembarang retakan yang memiliki derajat kebebasan besar, dalam program ini,perhitungan nilai J-Integral untuk program 3-D telah menunjukkan efektivitas denganmenghitung contoh retakan. Program ini menunjukkan distribusi tegangan pada bidang tegaklurus ke arah retak yang sulit untuk mendapatkan nilai J-Integralnya. Setelah itu kita dapatmenghitung J-integral Path pada permukaan. Hal penting dalam program post-processingadalah bagaimana cara mengevaluasi J-integral dan dapat menunjukkan distribusi teganganpada bidang yang tegak lurus terhadap retak. Kami telah membuat beberapa fungsi untukmengevaluasi nilai tersebut, seperti distribusi tegangan, untuk mendapatkan J-Integral Pathdengan menggunakan metode pemotongan, dimana hal ini tidak tergantung pada bentuk danletak mesh tersebut. Dengan menggunakan fungsi ini, evaluasi J-Integral dapat dengan mudahdilakukan dan didapat hasil dibandingkan dengan metode yang lain, dan hasil yang baikdiperoleh.Kata kunci: Adventure System, J-Integral, derajat kebebsan, retakanAbstract : ADVENTURE (Advanced Engineering Analysis Tools for large Ulra Real World) is Japanambitious project that uses the "fastest computer in the world 30-100 TFLOPS in 2002", but isalso used for the analysis GeoFEM designed to operate in the same virtual computingenvironment (Earth Simulator). Some of the technology used in this system includes a modulebasedarchitecture, the standardization of formats and libraries, efficient modeling, 3-Dvisualization for models 10-100000000 degrees of freedom (DOF) and can be used as parallelcomputer in a variety of environments. One of the problems that can be solved with theADVENTURE System is an analysis of cracks as the analysis J-Integral which has a largedegree of freedom. We have developed Post Program to analyze any cracks that have a largedegree of freedom, in this program, the calculation of the value of the J-Integral for 3-D programhas demonstrated effectiveness by counting the cracks examples. This program shows thestress distribution in the plane perpendicular to the direction of the crack is difficult to obtain Jintegralvalue. After that we can calculate the J-integral Path on the surface. It is important inthe post-processing program is how to evaluate the J-integral and can indicate stressdistribution in the plane perpendicular to the crack. We have made some functions to evaluatethese values, such as stress distribution, to obtain J-Integral Path using the cutting method,where it is not dependent on the shape and location of the mesh. By using this function, Jintegralevaluation can be easily performed and the obtained results are compared with othermethods, and good results are obtained.Keywords: Adventure System, J-Integral, degrees of freedom, cracks

This paper discusses the odor localization using Fuzzy logic algorithm. The concentrations of the source that is sensed by the gas sensors are used as the inputs of the fuzzy. The output of the Fuzzy logic is used to determine the PWM (Pulse Width Modulation) of driver motors of the robot. The path that the robot should track depends on the PWM of the right and left motors of the robot.Â When the concentration in the right side of the robot is higher than the middle and the left side, the fuzzy logic will give decision to the robot to move to the right. In that condition, the left motor is in the high speed condition and the right motor is in slow speed condition. Therefore, the robot will move to the right.Â Â The experiment was done in a conditioned room using a robot that is equipped with 3 gas sensors. Although the robot is still needed some improvements in accomplishing its task, the result shows that fuzzy algorithms are effective enough in performing odor localization task in mobile robot.

Masyarakat modern bepergian menggunakan kendaraan pribadi. Semakin banyaknya penggunaan kendaraan harus diimbangi dengan ketersediaan lahan parkir. Masalah ini dapat diatasi dengan membuat suatu system yang dapat mengetahui lokasi lahan parkir yang kosong untuk dapat di isi kendaraan. Identifikasi plat nomor menggunakan jaringan syaraf tiruan kohonen ini mempunyai beberapa tahapan, yaitu mobil yang memasuki lahan parkir akan melewati portal yang telah dipasangi webcam untuk mengambil citra dari mobil, lalu citra akan di resize dan melalui proses seperti grayscaling, vertical edge detection, dilasi, horizontal rank filter, lalu diperoleh lokasi plat nomor yang akan di identifikasi oleh program yang telah dibuat. Dilanjutkan dengan proses pemerataan latar belakang untuk memfokuskan program agar mendeteksi karakter dari plat nomor saja, tahap yang di lakukan pada proses ini antara lain adalah proses grayscaling, contrasting, binary, proses filter, dan membersihkan border dari plat. Selanjutnya proses mengekstraksi karakter satu per satu. Hasil di labelisasi itulah akan menjadi data inputan atau database untuk proses training, training menggunakan 3 sampel berbeda untuk setiap karakter nya. semakin banyak sampel semakin tinggi tingkat akurasi dari pembacaan program. Hasil dari uji coba program ini menghasilkan 65% keberhasilan mengenali pola huruf, 60% pola angka, dan 20% keberhasilan mengenali plat nomor dengan benar dari total percobaan 10 plat nomor.

Publisher : Institute of Advanced Engineering and Science

Classifying odor in real experiment presents some challenges, especially the uncertainty of the odor concentration and dispersion that can lead to a difficulty in obtaining an accurate datasets. In this study, to enhance the accuracy, datasets arrangement based on MOS sensors parameters using SVM approach for odor classification is proposed. The sensors are tested to determine the sensors' time response, sensors' peak duration, sensors' sensitivity, and sensors' stability when applied to the various sources at different range. Three sources were used in experimental test, namely: ethanol, methanol, and acetone. The gas sensors characteristics are analyzed in open sampling method to see the sensors' performance in real situation. These performances are considered as the base of choosing the position in collecting the datasets. The sensors in dynamic experiment have average of precision of 93.8-97.0%, the accuracy 93.3-96.7%, and the recall 93.3-96.7%. This values indicates that the collected datasets can support the SVM in improving the intelligent sensing when conducting odor classification work.
