We test the spectral–energy correlation including the new bursts detected (mostly) by Swift with firm measurements of their redshifts and peak energy. The problem of identifying the jet breaks is discussed in the complex and multibreak/flaring X–ray light curves observed by Swift. We use the optical data as the most reliable source for the identification of the jet break, since the X–ray flux m...

The cuttings-sticks problem is the following. We are given a bundle of sticks all having integer lengths. The total sum of their lengths is n(n+1)/2. Can we break the sticks so that the resulting sticks have lengths 1, 2, . . . , n? The problem is known to be NP-hard. We consider an optimization version of the problem which involves cutting the sticks and placing them into boxes. The problem ha...

We investigate a scheduling problem in which packets, or datagrams, may be fragmented. While there are a few applications to scheduling with datagram fragmentation, our model of the problem is derived from a scheduling problem present in data over CATV networks. In the scheduling problem datagrams of variable lengths must be assigned (packed) into fixed length time slots. One of the capabilitie...

Braid cryptosystem was proposed in CRYPTO 2000 as an alternate public-key cryptosystem. The security of this system is based upon the conjugacy problem in braid groups. Since then, there have been several attempts to break the braid cryptosystem by solving the conjugacy problem in braid groups. In this paper, we first survey all the major attacks on the braid cryptosystem and conclude that the ...
