We investigate a class of homeomorphisms of a cylinder, with all trajectories convergent to the cylinder base and one fixed point in the base. Let A be a nonempty finite or countable family of sets, each of which can be a priori an ω-limit set. Then there is a homeomorphism from our class, for which A is the family of all ω-limit sets.

This paper ditcusses the functions preseni in a sophisticated relation browser with support for icons, maps, text and normal fixed format relations. A discussion of some of the required data base extensions to support, such a browser is also presented. I INTRODUCTIOX This paper suggests the design of TIMBER (Text, icon and Map Browser for Extended Relations), a user friendly, graphics-oriented ...

We propose online prediction algorithms for data streams whose characteristics might change over time. Our algorithms are applications of online learning with experts. In particular, our algorithms combine base predictors over sliding windows with different length as experts. As a result, our algorithms are guaranteed to be competitive with the base predictor with the best fixed-length sliding ...

DNA duplexes fixed in anti-parallel and parallel orientations by introducing covalent linkages have been synthesized and metal ions, Hg(II) and Ag(I), were incorporated into pyrimidine-pyrimidine base pairs.

The introduction of smart capabilities in broadband fixed and mobile wireless access networks employing optically beamformed base station antennas is proposed and evaluated through simulation. Novel strategies and algorithms to address dynamically changes in the network conditions, in order to optimise the network performance, are presented. The impact on the network performance is analysed dem...

Certain high speed industrial assembly robots share a peculiar three legged parallel architecture wherein three “hips”, attached to a fixed upper base or “pelvis”, actuate “thighs” connected by “knees” to “shins”. Each shin is a parallelogramic four-bar linkage. “Ankles” are connected to a common end effector “foot” which executes spatial translatory motion. Inverse and direct kinematic analyse...

We show that the family of tree languages recognized by weak alternating automata is closed by three set theoretic operations that correspond to sum, multiplication by ordinals < ω, and pseudoexponentiation with the base ω1 of the Wadge degrees. In consequence, the Wadge hierarchy of weakly recognizable tree languages has the height of at least ε0, that is the least fixed point of the exponenti...

IEEE 802.16 standard supports two different topologies: point to multipoint (PMP) and Mesh. In this paper, a QoS mechanism for point to multipoint of IEEE 802.16 and BS scheduler for PMP Mode is proposed. This paper also describes quality of service over WiMAX networks. Average WiMAX delay, Average WiMAX load and Average WiMAX throughput at base station is analyzed and compared by applying diff...

We consider a two-stage production-inventory system with demand at the downstream stage and returns at each stage. We characterize the structure of the optimal policy which is a complex state-dependent Base-stock policy. We also investigate four classes of policies : Fixed buffer, Base-stock echelon, Kanban and Half-optimal. We compare the performances of these policies and exhibit that the max...
