Abstract-Simulation methodology has become popular among network researchers due to the availability of various sophisticated and the flexibility of simulation packages in model construction and the result's validation. The objective of our research is to introduce a discrete simulator tools known as SimEvents toolbox that runs on MATLAB-Simulink with the advantages of graphical user interface (GUI) system and a total customized simulator design. In this paper, we design a model-based network simulator named as "CDNlink". CDNlink is designed based on a queuing model and functioned to study the content delivery networks (CDN). As a result, we have designed the simulator for Client, Router, DNS, and Server. Moreover, we simulate the CDN system for packet round trip time (RTT) and server's queue length.
Abstrak. The existence of Micro, Small and Medium Enterprises (MSME) has an important function in the growth of the economics of Indonesia. The purpose of this research is to find out how to increase awareness and mastery of ecommerce technology so that MSMEs in the city of Bandung. The method used in this research is the quantitative-qualitative mixed approaches from Cresswell (2003). Qualitative approach is done from doing training programs to increase knowledge and awareness, while the qualitative approach will be done by accompanying the MSMEs during implementation. The result of this research shows that the training programs are very effective at increasing the knowledge and awareness of MSMEs in taking advantage of e-commerce technologies as a online marketing media. After being given training, MSMEs knowledge and mastery of e-commerce technologies increase with an average rate of 76,4%. Through accompaniment, 70% of the subjects had succeeded at implementing e-commerce, by creating and managing online stores in shopee, although had not been completely successful in managing it. Abstrak. Keberadaan Usaha Mikro, Kecil, dan Menengah (UMKM) mempunyai peranan yang sangat penting dalam pertumbuhan ekonomi di Indonesia. Tujuan dari penulisan ini adalah bagaimana upaya peningkatan pengetahuan dan penguasaan teknologi e-commerce para pelaku UMKM di Kota Bandung. Metode yang digunakan dalam penelitian ini adalah pendekatan mixed approaches kuantitatif-kualitatif dari Cresswell (2003). Pendekatan kuantitatif dilakukan melalui kegiatan pelatihan untuk meningkatkan pengetahuan, sedangkan pendekatan kualitatif dilakukan melalui kegiatan pendampingan untuk implementasinya. Hasil dari penelitian ini menunjukkan bahwa kegiatan pelatihan sangat efektif dalam upaya meningkatkan pengetahuan peserta dalam pemanfaatan teknologo e-commerce sebagai media pemasaran online. Setelah diberikan pelatihan, pengetahuan dan penguasaan teknologi ecommerce para pelaku UMKM semakin meningkat, dengan rata-rata peningkatan mencapai 76,4%. Melalui kegiatan pendampingan, 70% peserta telah berhasil mengimplementasikan ecommerce, yaitu dengan membangun dan mengelola toko online di marketplace shopee, akan tetapi dalam pengelolaannya masih belum optimal.
Prinsip Duhamel menyiratkan adanya suatu metoda matematika tertentu untuk menyelesaikan sebuah persamaan diferensial linier orde dua tak homogen dengan koefisien konstan. Penelusuran teori terhadap pengertian transformasi integral menunjukan adanya suatu cara yang dapat digunakan dalam menentukan penyelesaian khusus persamaan diferensial tersebut. Dalam artikel ini ditunjukan bahwa operasi konvolusi sebagai transformasi integral yang melibatkan dua buah fungsi merupakan penyelesaian khusus dari suatu persamaan diferensial yang memenuhi prinsip Duhamel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
