Many labs today wish to transfer data between their EDS systems and their existing PCs and minicomputers. Our lab has implemented SpectraPlot, a low- cost PC-based system to allow offline examination and plotting of spectra. We adopted this system in order to make more efficient use of our microscopes and EDS consoles, to provide hardcopy output for an older EDS system, and to allow students to access their data after leaving the university.As shown in Fig. 1, we have three EDS systems (one of which is located in another building) which can store data on 8 inch RT-11 floppy disks. We transfer data from these systems to a DEC MINC computer using “SneakerNet”, which consists of putting on a pair of sneakers and running down the hall. We then use the Hermit file transfer program to download the data files with error checking from the MINC to the PC.

VoIP (Voice over Internet) dikenal juga dengan sebutan IP (Internet Protocol) Telephony saat ini semakin banyak digunakan karena memiliki beberapa keunggulan, salah satu diantaranya yaitu tarif yang jauh lebih murah daripada tarif telepon tradisional sehinggapengguna telepon dapat memilih layanan tersebut sesuai dengan kebutuhannya. VoIP dapat mereduksi biaya percakapan sampai 70%. Selain memiliki beberapa keunggulan di atas,VoIP juga memiliki kelemahan yang sangat vital yaitu dari segi keamanan transfer suarakarena berbasis IP, sehingga siapapun bisa melakukan penyadapan dan perekaman terhadap data VoIP. Ganguan yang terjadi pada sistem VoIP ada berbagai macam diantaranya, transferdata yang lewat pada suatu jaringan seperti misalnya dapat disalahgunakan (abuse), dapatdibajak isi data tersebut (sniffing), dan tidak dapat mengakses server dikarenakan server yang kelebihan muatan (Denial of Services).Ada beberapa cara untuk mengamankan komunikasi data VoIP, antara lain, dengan mengamankan jalur yang digunakan pengguna untuk melakukan komunikasi VoIP denganmenggunakan metode VPN (Virtual Private Network) dan juga dapat dilakukan suatu metode kriptografi pada aplikasi VoIP tersebut sehingga data yang dikirimkan dapat dilindungidengan baik. VPN adalah teknik pengaman jaringan yang bekerja dengan cara membuat suatu tunnel sehingga jaringan yang dipercaya dapat menghubungkan jaringan yang ada diluar melalui internet. Titik akhir dari VPN adalah tersambungnya Virtual Channels (VCs)dengan cara pemisahan. Kenyataannya koneksi sebuah end-to-end VPN tergantung dari sebuah nilai dari hubungan daripada titik-titiknya. VPN mempunyai dua metode dalampengamanan yakni IPSec dan Crypto IP Encapsulation (CIPE). Selain itu dapat dipergunakan teknik Kriptografi (cryptography) yang merupakan ilmu dan seni penyimpanan pesan, data,atau informasi secara aman.Sistem VoIP menggunakan VPN ini diharapkan dapat memberikan keamanan transfer data pada jaringan internet maupun intranet.

In this project, we demonstrated how to improve transfer rate when transfering data from a notebook installed FreeBSD operating system to another notebook installed Windows 8 operating system. The method which we used was with customizing the kernel on FreeBSD. Before we customized the kernel, we calculated the average time of the transfer speed with its default kernel. After we got the average time, then we customized its kernel and calculated the average time after we installed the custom kernel. At the end we got faster average time with the customized kernel and the performance better. Index Terms - FreeBSD, Server, Transfer rate, Improving

Method Of Calculation

The results are presented from a numerical finite-difference method of calculation for the transient behavior of porous media when subjected to a step change in fluid temperature considering the case where the longitudinal thermal heat conduction cannot be neglected. These results, given in tabular and graphical form, provide a useful means for evaluating the heat-transfer data obtained from the transient testing of compact heat-exchanger surfaces.

Incompressible Boundary

The van Driest damped mixing length has been extended to account for the effects of mass transfer through a porous plate into a turbulent, two-dimensional incompressible boundary layer. The present mixing length is continuous from the wall through to the inner-law region of the flow, and although empirical, has been shown to predict wall shear stress and heat transfer data for a wide range of blowing rates.
