In this paper, the redundancy resolution methods for elastic joint redundant robots are researched. First, a redundancy resolution method called MD method is proposed by using joint elastic deflection as a performance index. And then, the influence of robots’ initial configuration on this method is discussed. Finally, simulations for a planar 3R redundant robot with elastic joints are conducted...

Adding and removing redundant clauses is at the core of state-of-the-art SAT solving. Crucial is the ability to add short clauses whose redundancy can be determined in polynomial time. We present a characterization of the strongest notion of clause redundancy (i.e., addition of the clause preserves satisfiability) in terms of an implication relationship. By using a polynomial-time decidable imp...

Rigidity theory enables us to specify the conditions of unique localizability in the cooperative localization problem of wireless sensor networks. This paper presents a combinatorial rigidity approach to measure (i) generic rigidity and (ii) generalized redundant rigidity properties of graph structures through graph invariants for the localization problem in wireless sensor networks. We define ...

The Poisson-sampling technique eliminates dependencies among symbol appearances in a random sequence. It has been used to simplify the analysis and strengthen the performance guarantees of randomized algorithms. Applying this method to universal compression, we relate the redundancies of fixed-length and Poisson-sampled sequences, use the relation to derive a simple single-letter formula that a...

With rapid population growth over the past 30 years and no significance seismic activity during this period, the unchecked development of the built environment in Bangladesh has been resulted in little resilience to earthquake. Identifying buildings due to this unchecked development that has high vulnerability is of critical importance both for reliable loss estimation as a result of an expecte...

Wireless Sensor Networks (WSNs) incorporate smart antennas for information propagation to offer connected coverage with reduced interference. This paper presents an omni directional antenna assisted scheme for WSNs to reduce network redundancy besides offering connected coverage. The directivity of an omni directional antenna outfitted on a sink node is exploited to reduce network redundancy an...

Association rule mining is known to be computationally intensive, yet real-time decisionmaking applications are increasingly intolerant to delays. The state-of-the-art PARAS 1 solution, a parameter space framework for online association mining, enables efficient rule mining by compactly indexing the final ruleset and providing efficient query-time redundancy resolution. Unfortunately, as many a...

One of the primary concerns in any system design problem is to prepare a highly reliable system with minimum cost. One way to increase the reliability of systems is to use redundancy in different forms such as active or standby. In this paper, a new nonlinear multi- objective integer programming model with the choice of redundancy strategy and component type is developed where standby strategy ...

The uniaxial compressive strength (UCS) is classified as one of the basic mechanical properties rocks, which widely used in mining and construction practice. For example, it allows geomechanics to classify individual rocks soils into groups with same or similar properties. An example (RMR) Rock Mass Rating, Barton’s Q system. [1,2]. As a rule, only an indicative determination sufficient for thi...
