Optimal spline spaces for L2L^2 nn-width problems with boundary conditions

In this paper we show that, with respect to the $L^2$ norm, three classes of functions in $H^r(0,1)$, defined by certain boundary conditions, admit optimal spline spaces of all degrees $\geq r-1$, and all these spline spaces have uniform knots.Comment: 17 pages, 4 figures.

Pembagian Peran dalam Pengambilan Keputusan Pembelian Keluarga

Keluarga memiliki struktur sendiri dan kompleks, tiap anggota atau beberapa anggota dalam keluarga memainkan peran masing-masing dalam pengambilan keputusan pembelian. Karenanya bagaimana masing-masing anggota keluarga mengambil peran dalam pengambilan keputusan pembelian produk menjadi perhatian dalam pemasaran. Kajian ini bersifat deskriptif untuk memperoleh gambaran tentang peran anggota keluarga dalam pengambilan keputusan pembelian TV. Dapat disimpulkan bila peran initiator dominan dipegang oleh istri, peran influencer cenderung oleh anak. Sedangkan suami lebih memegang peran sebagai decider sekaligus buyer. Selanjutnya peran sebagai user sebagai penikmat TV baru adalah anak. Kata kunci: Pengambilan Keputusan Pembelian, Keluarga, Pera

Transverse Lattice QCD in 2+1 Dimensions

Following a suggestion due to Bardeen and Pearson, we formulate an effective light-front Hamiltonian for large-N gauge theory in (2+1)-dimensions. Two space-time dimensions are continuous and the remaining space dimension is discretised on a lattice. Eguchi-Kawai reduction to a (1+1)-dimensional theory takes place. We investigate the string tension and glueball spectrum, comparing with Euclidean Lattice Monte Carlo data.Comment: 4 pages LaTeX with 2 Postscript figures, uses boxedeps.tex and e spcrc2.sty.

A phase-space approach to directional switching in semiconductor ring lasers

We show that a topological investigation of the phase space of a Semiconductor Ring Laser can be used to devise switching schemes which are alternative to optical pulse injection of counter-propagating light. To provide physical insight in these switching mechanisms, a full bifurcation analysis and an investigation of the topology is performed on a two-dimensional asymptotic model. Numerical simulations confirm the topological predictions.Comment: 9 pages, 7 figure
