Di zaman yang sudah sangat berkembang saat ini, komunikasi menjadi suatu hal yang sangat diperlukan baik dalam pernyerangan dan pertahanan didalam suatu negara, juga informasi di kehidupan sehari-hari. Namun dengan tidak adanya pengaturan yang efektif dalam suatu hubungan informasi yang dilakukan maka perlu adanya suatu pengaturan server yang akan mempermudah dalam berkomunikasi, sehingga dengan jarak yang jauh bisa dilakukan komunikasi dengan efektif tanpa ada kendala yang signifikan. Penelitian ini menjelaskan bagaimana penerapan management server yang digunakan pada jaringan Radio Hybrid yang bisa menghubungkan radio analog berupa HT (Handy Talkie) dan radio militer lainnya maupun radio digital dengan perangkat handphone yang berbasis android yang digabungkan dengan internet. Untuk penerapan suatu server diperlukan beberapa perangkat pendukung berupa PC (Personal Computer) yang akan menjadi pengontrol, pengatur serta memonitor jalur komunikasi yang dilakukan setiap client. Dalam PC tersebut harus disertai dengan spesifikasi yang memadai dan software yang sudah dirancang khusus agar komunikasi dapat berjalan sesuai dengan keinginan. Software yang digunakan adalah software open source dengan penambahan script program sebagai pendukung dalam pembuatan server yang dihubungan dengan banyak client.

Router very important for computer network. To get the router can buy a router products but can also design your own using personal computers. Mikrotik is one of the router manufacturer that provides products in the form of hardware or software. If you want to pay less to design a router can use operating system Ubuntu. This operating system is open source and provided free of charge by the manufacturer. If you want to design a router with this OS can make use of personal computers are often used in homes or offices. Merging the performance of both types of routers can also be usedto cover the lack of one another. With the proxy on a local network then the use of bandwidth can be saved. Becausethere are several websites cached and stored therein if the same website is accessed by other users, the router transmits only from the proxy to the computerwhich make the request.

Spectrum Imaging

As interest for parallel EELS spectrum imaging grows in laboratories equipped with commercial spectrometers, different approaches were used in recent years by a few research groups in the development of the technique of spectrum imaging as reported in the literature. Either by controlling, with a personal computer both the microsope and the spectrometer or using more powerful workstations interfaced to conventional multichannel analysers with commercially available programs to control the microscope and the spectrometer, spectrum images can now be obtained. Work on the limits of the technique, in terms of the quantitative performance was reported, however, by the present author where a systematic study of artifacts detection limits, statistical errors as a function of desired spatial resolution and range of chemical elements to be studied in a map was carried out The aim of the present paper is to show an application of quantitative parallel EELS spectrum imaging where statistical analysis is performed at each pixel and interpretation is carried out using criteria established from the statistical analysis and variations in composition are analyzed with the help of information retreived from t/γ maps so that artifacts are avoided.

For many years the concept of quantitative diffraction contrast experiments might have consisted of the determination of dislocation Burgers vectors using a g.b = 0 criterion from several different 2-beam images. Since the advent of the personal computer revolution, the available computing power for performing image-processing and image-simulation calculations is enormous and ubiquitous. Several programs now exist to perform simulations of diffraction contrast images using various approximations. The most common approximations are the use of only 2-beams or a single systematic row to calculate the image contrast, or calculating the image using a column approximation. The increasing amount of literature showing comparisons of experimental and simulated images shows that it is possible to obtain very close agreement between the two images; although the choice of parameters used, and the assumptions made, in performing the calculation must be properly dealt with. The simulation of the images of defects in materials has, in many cases, therefore become a tractable problem.

High-resolution transmission electron microscopy must attain utmost accuracy in the alignment of incident beam direction and in astigmatism correction, and that, in the shortest possible time. As a method to eliminate this troublesome work, an automatic alignment system using the Slow-Scan CCD camera has been introduced recently. In this method, diffractograms of amorphous images are calculated and analyzed to detect misalignment and astigmatism automatically. In the present study, we also examined diffractogram analysis using a personal computer and digitized TV images, and found that TV images provided enough quality for the on-line alignment procedure of high-resolution work in TEM. Fig. 1 shows a block diagram of our system. The averaged image is digitized by a TV board and is transported to a computer memory, then a diffractogram is calculated using an FFT board, and the feedback parameters which are determined by diffractogram analysis are sent to the microscope(JEM- 2010) through the RS232C interface. The on-line correction system has the following three modes.
