Pendeteksian Tepi Objek Menggunakan Metode Gradien

Pada tahap melakukan ekstraksi ciri (feature extraction) faktor yang sangat penting adalah kemampuan untuk mendeteksi keberadaan tepi di dalam citra. Tujuan penelitian ini adalah menggunakan konsep matematis untuk melakukan fungsi pendeteksian tepi. Uji coba yang dilakukan menggunakan matlab versi R2009a dengan menggunakan citra masukan berupa citra abu-abu (grayscale). Setiap citra diuji dengan menggunakan 3 cara yaitu menggunakan metode gradien citra, gradien Prewitt dan gradien Sobel. Cara kerja dari metode gradien terdiri dari gradien horizontal arah x menghasilkan tepi objek berupa garis vertikal dan diagonal dari citra input, gradien arah vertikal y menghasilkan tepi objek berupa garis horizontal dan diagonal dari citra input sedangkan total gradien merupakan gabungan dari gradien arah x dan gradien arah y sedangkan cara kerja dari untuk metode gradien Prewitt dan Sobel, pemilteran dilakukan secara parsial dengan arah yang berlawanan dengan arah fungsi turunan pertama, bila pemilteran dilakukan dalam arah y maka turunan pertama dari hasil pemilteran dilakukan dalam arah x. Pendeteksian tepi menggunakan gradien Prewitt dan Sobel merupakan hasil gabungan dari konvolusi gradien Prewitt/Sobel arah x dengan gradien Prewitt/Sobel arah y. Hasil uji coba dari penelitian ini memperlihatkan bahwa pendeteksian tepi menggunakan gradien Sobel lebih tajam dibandingkan dengan gradien Prewitt dan gradien citra

Multi-document Summarization Based on Sentence Clustering Improved Using Topic Words

Informasi dalam bentuk teks berita telah menjadi salah satu komoditas yang paling penting dalam era informasi ini. Ada banyak berita yang dihasilkan sehari-hari, tetapi berita-berita ini sering memberikan konten kontekstual yang sama dengan narasi berbeda. Oleh karena itu, diperlukan metode untuk mengumpulkan informasi ini ke dalam ringkasan sederhana. Di antara sejumlah subtugas yang terlibat dalam peringkasan multi-dokumen termasuk ekstraksi kalimat, deteksi topik, ekstraksi kalimat representatif, dan kalimat rep-resentatif. Dalam tulisan ini, kami mengusulkan metode baru untuk merepresentasikan kalimat ber-dasarkan kata kunci dari topic teks menggunakan Latent Dirichlet Allocation (LDA). Metode ini terdiri dari tiga langkah dasar. Pertama, kami mengelompokkan kalimat di set dokumen menggunakan kesamaan histogram pengelompokan (SHC). Selanjutnya, peringkat cluster menggunakan klaster penting. Terakhir, kalimat perwakilan yang dipilih oleh topik diidentifikasi pada LDA. Metode yang diusulkan diuji pada dataset DUC2004. Hasil penelitian menunjukkan rata-rata 0,3419 dan 0,0766 untuk ROUGE-1 dan ROUGE-2, masing-masing. Selain itu, dari pembaca prespective, metode kami diusulkan menyajikan pengaturan yang koheren dan baik dalam memesan kalimat representatif, sehingga dapat mempermudah pemahaman bacaan dan mengurangi waktu yang dibutuhkan untuk membaca ringkasan

Factors controlling micropropagation of Myrica esculenta buch. – Ham. ex D. Don: a high value wild edible of Kumaun Himalaya

Various factors such as browning, season, media type and plant growth regulators influence the micropropagation of female trees of Myrica esculenta. These factors have successfully been addressed after addition of some media additives, collection of the explant at right season, standardizing the media type and use of plant growth regulators at varying concentrations. Polyvinylpyrollidone (PVP - 0.5%) was found effective for successful partial removal of phenolic compounds and obtaining maximum percent survival of explants. The explant collection season played an important role in reducing phenol induced browning and winter season was found best for explant establishment. The maximum number of shoots (4-5/explant) was obtained in Woody Plant Medium (WPM) supplemented with 10µM kinetin and 0.1µM naphthalene acetic acid (NAA). Of all the media types tried, Woody Plant Medium was found to be the best. Kinetin was found superior to benzyl amino purine and N6(γ,γ-dimethylallyamino)purine (2iP) for explant establishment and multiplication. NAA induced rooting to 45.8% of explants in 1/2 strength Woody Plant Medium. However, ex vitro survival percentage was low. Key Words: Browning, in vitro, plant regeneration, tissue culture, woody plant medium. African Journal of Biotechnology Vo l.3(10) 2004: 534-54

Geotechnical Assessment and Evaluation of the Impact of Kachchh (Bhuj) India 2001 Earthquake

Intraplate earthquakes are ongoing activity in the Kachchh region. The area is seismically active and falls in Zone V of the seismic Zoning Map of India. The devastating Bhuj (Kachchh) Earthquake of MS 7.6 occurred in this zone on 26th January, 2001 causing severe damage to civil engineering structures and loss of human life. The surface manifestations of deformation of this earthquake include fractures/ fissures, lateral spread, slump, subsidence, upheaval, sand blows and craters. Bhuj Earthquake has caused considerable damage to earth dams lying in isoseist VIII and above in Kachchh. Damages to dams are in the form of longitudinal and transverse cracks, differential settlement, slumps/ slide, displacements and in some cases leakage. A review of the available geological, seismological and geotechnical data have been done to asses the impact of Bhuj Earthquake and subsequent seismic events in the area on ground deformation and engineering structures. Main cause of the ground deformation and damage is liquefaction of the soil under seismic shaking. Tectonic influence on the development of fissures/ cracks on the ground as well as on the earth dams has been observed

Penggunaan Metode New Information Economics Untuk Meningkatkan Kinerja USAha Melalui Sistem Informasi

PFI is a financing institution (multifinance) that since 2004, focusing on consumer finance who want to own a motorcycle. PFI has been utilizing the information system and technology (IS/IT) in the overall business processes both on the system application is currently running (lights on), infrastructure, services, management and application projects planning. The research objective was to give a clear picture to the management about benefits and impacts that can be obtained from the IS/ IT investment both lights on and appplication projects. Researchers propose to analyze the lights on and the application projects is using the New Information Economics (NIE) and uses four of the NIE five practices that are Demand/Supply Planning, Innovation, Prioritization, and Alignment. The research result is an IS/IT strategy investment in the lights on, fulfilling the needs of the IS/IT, the creation of new innovations, as well as priority application projects based on the company\u27s strategic direction. Conclusions obtained are the company can find out where the lights on should be developed, improved, or even ignored. And to knowing which application projects should take precedence, so the company can allocate future resources to the lights on and the right application projects that supports corporate strategic direction
