We describe gauge-fixing at the level of virtual paths in the path integral as a nonsymplectic BRST-type of flow on the path phase space. As a consequence a gauge-fixed, non-local symplectic structure arises. Restoring of locality is discussed. A pertinent anti-Lie-bracket and an infinite dimensional group of gauge fermions are introduced. Generalizations to Sp(2)-symmetric BLT-theories are mad...

we give an algorithm, called t*, for finding the k shortest simplepaths connecting a certain pair of nodes, s and t, in a acyclic digraph.first the nodes of the graph are labeled according to the topologicalordering. then for node i an ordered list of simple s − i paths iscreated. the length of the list is at most k and it is created by usingtournament trees. we prove the correctness of t* and ...

This paper provides closed-form equations parameterizing the 2 smooth path that globally minimizes the Euclidean norm of a robot’s peak base reaction force while avoiding obstacles during three-dimensional maneuvers in a gravity-free environment. In addition, the paper describes a computationally efficient technique that leads to a path typically having a peak force within 5% of the optimal pat...

In this paper, two basic approaches for kinematics modelling of multiple manipulator Space Free-Flying Robots (SFFRs) are developed. In the barycentric vector approach, the center of mass of the whole system is taken as a representative point for the system’s translational motion, and a set of body-fixed vectors which reflect both geometric configuration and mass distribution of the system are ...

The new concepts of repelling inequalities, repelling paths, and prime analytic centers are introduced. A repelling path is a generalization of the analytic central path for linear programming, and we show that this path has a unique limit. Furthermore, this limit is the prime analytic center if the set of repelling inequalities contains only those constraints that ‘‘shape’’ the polytope. Becau...

Combining edge processing (at data capture site) with analysis carried out while data is enroute from the capture site to a data center offers a variety of different processing models. Such in-transit nodes include network data centers that have generally been used to support content distribution (providing support for data multicast and caching), but have recently started to offer user-defined...

A widely tunable 4th order BPF based on the subtraction of two 2nd order 4-path passive-mixer filters with slightly different center frequencies is proposed. The center frequency of each 4-path filter is slightly shifted relative to its clock frequency (one upward and the other one downward) by a gm-C technique. Capacitive splitting of the input signal is used to reduce the mutual loading of th...

<em>The goal of this study was to analyze and determine the positive significant influence competence on employee performance through motivation as an intervening variable. The subject research is all employees Bekasi productivity improvement center by using a quantitative approach method. Meanwhile, pattern relationships between variables in study, path analysis with aim direct or indire...

This paper characterizes polygons that are small-time locally controllableby stable pushing as a function of the polygon shape, the location of the center of friction, and the friction coefficient at the pushing contact. Such polygons can be pushed to follow any path arbitrarily closely, a useful property for planar manipulation. Because the pushes are stable, pushing plans can be executed with...
