"We impose the Higgs mechanism to break the Grand Unified Theory based on SU(6) symmetry, SU(6) GUT. We investigate and search for the Higgs multiplets which are approriate to generate masses for both fermions and gauge bosons. We have found that the most minimal Higgs multiplets are < 15 >,< 20 > and < 21 > to realize three steps of symmetry breaking in SU(6) GUT down to the standar SU(2) × U(1) model. However within this minimal SU(6) GUT, we can reproduce only some fermions spectra as N4e, νe,N6e, Ne and d quarks, although we have deployed the most general forms of Higgs multiplets. On the other hand, the present approach have succeeded in generating the reguler gauge bosons, W±, Z0 and Aµ."

"Telah dibangun Lagrangian baru serta dilakukan perhitungan analitik tensor energi-momentum untuk fluida QCD yang mengandung suku viskositas. Suku viskositas ini dibuat dengan asumsi bahwa persamaan gerak yang diperoleh mereproduksi persamaan gerak hidrodinamika relativistik. Suku viskositas mengakibatkan perusakan simetri fluida QCD. Memakai Lagrangian yang telah dibangun, dihitung distribusi jumlah partikel memakai teori kinetik dan resolusi Cooper- Frye. Ditunjukkan bahwa distribusi jumlah partikel memiliki kontur yang samamdengan hasil perhitungan sebelumnya memakai persamaan gerak hidrodinamika relativistik.

A new Lagrangian and energy momentum tensor for fluid QCD with viscous term have been developed and calculated analytically. The viscous term has been constructed assuming that the generated equation of motion should reproduce the known relativistic hydrodynamics. The viscous term induces symmetry breaking of fluid QCD. Using the Lagrangian, the particle number distribution has been calculated using kinetic theory and Cooper-Frye prescription. It is shown that the distribution has the same contour as previous results calculated using the equation of motion of relativistic hydrodynamics."

"Reed Solomon (RS) codes is a mechanism to detect and correct burst of errors in data transmission and storage systems.It provides a solid introduction to foundation mathematical concept of Galois Field algebra and its application. With thedevelopment of digital hardware technology, the RS concepts were brought into reality, i.e. the implementation of RScodec chips. This paper presents the development steps of a generic RS encoder using VHDL. The encoder is able tohandle generic width of data, variable length of information, number of error as well as variable form of primitivepolynomial and generator polynomial used in the system. The design has been implemented for FPGA chip XilinxXC3S200-5FT256 and has a better performance than commercially available equivalent encoder."
