Metode yang digunakan dalam penelitian ini menggunakan rancang bangun pemodelan dalam perangkat lunak FreeFem++ yang disesuaikan atau mendekati semirip mungkin dengan kondisi pembuluh darah carotid. Pada tahap awal terlebih dahulu dibuat mesh untuk pola percabangan sesuai dengan pola dan diameter pembuluh carotid, kemudian dibuat mesh pembuluh carotid normal, selanjutnya dibuat mesh carotid stenosis dengan penyumbatan pembuluh 40% dan pembuatan mesh pembuluh darah carotid stenosis dengan penyumbatan pembuluh 60%. Buildmesh yang telah dibuat kemudian dibuat program simulasinya dengan iterasi sebesar 15 kali. Hasil aktivasi pada simulasi pola aliran dengan iterasi 15 kali daidapat hasil bahwa pada pembuluh carotid normal pola aliran yang didapat ...

Agar interaksi ini dapat dilakukan, robot perlu memiliki kemampuan mengenali lingkungannya. Kemampuan ini dapat diperoleh dengan menggunakan sensor untuk menangkap informasi dari dunia luar. Salah satu sensor yang dapat dipakai adalah kamera. Sensor kamera memiliki fungsi untuk menangkap informasi dari dunia luar dalam bentuk gambar. Dengan sensor kamera, robot mobile dapat dikembangkan untuk mengikuti objek, misalnya manusia. Fungsi ini dapat meningkatkan peran robot sebagai asisten manusia. Dengan mengikuti manusia kemanapun dia berjalan, robot akan selalu berada di dekat manusia. Peran ini memerlukan kemampuan pengenalan objek yang baik, apalagi jika manusia yang diikuti berada di tengah keramaian. Pada tugas akhir ini dirancang sistem pelacakan warna dan sistem penanganan halangan menggunakan Kalman filter pada robot beroda. Robot mengikuti manusia dengan melacak warna target dan mengikuti perpindahan target. Kalman filte...

The problems that will be the focus of the author's thesis is fire problems that often occur in the housing. At first fire only occurred in one house, but if the fire not treated immediately will spread to other houses. Rapid handling on fire can prevent more serious risk. Because home owners often did not realize if there is a fire in one part of the house. In addition, the accuracy of firefighters in determining the point of the event will be one of the concerns in the manufacture of fire warning system. Based on the above problems, this thesis proposed a control system at home that will work automatically when the fire is indicated at the house. When the room in the house indicated there is a fire, the buzzer in the room will give a warning sound. Then, to reduce the risk of fire , the system will cut electricity lines in the house and sprayed water in the room. In a...

Implementasi Sistem Siaran FM Stereo Plus Data-Text Sca (Subsidiary Communication Authorization)

TEKTRIKA - Jurnal Penelitian dan Pengembangan Telekomunikasi, Kendali, Komputer, Elektrik, dan Elektronika

Penyisipan informasi lain pada ruang sisa spasi kanal tersebut biasa disebut SCA (Subsidiary Communication Authorization), yang bertujuan untuk meningkatkan efisiensi penggunaan alokasi spektral FM. Penelitian ini mengusulkan penyisipan informasi berupa sinyal Data Text digital termodulasi FSK (Frequency Shift Keying) sebagai fasilitas siaran tambahan. Informasi Data-Text diperoleh dari deretan kode biner serial berkecepatan 1200 bps yang dibangkitkan dari port RS-232 komputer. Sinyal FSK Data-Text tersebut dimodulasikan ke subcarrier 67 KHz untuk selanjutnya digabungkan dengan sinyalsinyal multipleks audio stereo. Seluruh sinyal komposit dipancark...

Packet loss analysis in finite buffer with ATDMA single channel output scheme for broadband PLC network

However, data traffic characteristic is largely affected by either electric power system dynamics or electric power load variation. Therefore, the statistical data information of network condition is an important issue

The Performance of Saturated Packet Queue System On Broadband PLC Network

Random data traffic passing through the slave-station of synchrophasor-sensor network can be viewed as packet entering of a queue. Since the length of queue is limited the packet loss may occur. This negatively affects the queuing system performance. Our numerical evaluation shows that for 1,000 random packet arrival, with 14-150 Mbps arrival rate, 100 Mbps service rate, and 64 Mbit buffer capacities, there is average packet loss of 6.75 %. If the buffer capacity is increased to 128 Mbit, then average of packet loss is reduced to 6.69 %. Our numerical test shows that the option to increase queue service rate may reduce packet loss probability more significantly than to increase the buffer capacity of the queue system.

Performance and Fairness Analysis (using Jain's Index) of AODV and DSDV based on ACO in MANETs

One of the challenges of research in MANETs is constant topology changes which make initially efficient network become inefficient. AODV routing protocol and DSDV have a flaw in their mobility network such as an increase in routing overhead. It causes frequent drop-link which makes the source node routing need to be built again from scratch. In the case of simultaneous data transmission, there will be an increase in the drop packet value and a decrease in throughput value. The contribution of this study includes 1) modifying the DSDV and AODV routing protocol to solve some weaknesses using the advantages of the characteristics of the Ant Colony Optimization, 2) making comparisons of performance and fairness on AODV and DSDV using Ant Colony Optimization. The results showed the modifications done to the conventional AODV routing protocol and DSDV by adding Antnet algorithm could produce better performance. The throughput value increased approximately 6.367%-13.02% for AODV and 0.68%-5.47% for DSDV. However, the modifications worsen the value of delay time by approximately 5.23%-6.02% for AODV and 60.88-65.82% for DSDV. AODV routing protocol performance is still better than DSDV routing protocol despite of having Antnet algorithm added on both protocols. Similarly, the value of Fairness Index AODV is better than DSDV.
