In recent times, there has been significant interest in collaborative robots where the tasks performed by a robot are non-repetitive and complex, and humans and robots share an overlapping workspace. In such a case, the robot controller must necessarily be safety-aware. In this paper, we propose a mechanism to evaluate a robot program and compute a safety score for each action that the robot is about to perform. To this end, we have implemented a code analyzer that examines the robot's Move instructions and assigns a safety score. A subjective logic based approach is used to compute the safety score for each instruction. We have evaluated the approach through ABB's RobotStudio (R) simulator. We simulate two scenarios: First, where two robots share a workspace and second, where a robot moves along a path with an obstacle. the simulations show that using our code analyzer and safety score formalism;it is possible to evaluate the application code for safety and enable avoidance of potentially unsafe behavior.

Girard's Linear logic is a formalism which can be used to manage a lot of problems with consumable resources. Its expressiveness is quite good for an easily understandable encoding of many problems. We concentrated on expressing planning problems by linear logic in this paper. We observed a rich usage of a construct of consumable resources in planning problem formulations. this fact motivates us to provide a possible encoding of planning problems in linear logic. this paper shows how planning problems can be encoded in Linear logic and how some optimizations of planning problems can be encoded. these optimizations can help planners to improve the efficiency of finding solutions (plans).

this paper includes the main notions associated withthe syntax and semantics of two interesting paradigms in fuzzy logicprogramming with default negation: multi-adjoint normal logicprogramming introduced in [5] and the fuzzy answer set logicprogramming approach presented in [16]. We will show that fuzzy answer set logic programs can be translated into multi-adjoint normal logic programs, as long as the implication operator used in the former is a residuated implication. Moreover, we will relate the notions of fuzzy y-model and model by means of a characterization theorem which allow us to guarantee the existence of fuzzy y-models of fuzzy answer set logic programs.

We give a calculus of proof-nets for classical propositional logic. these nets improve on a proposal due to Robinson by validating the associativity and commutativity of contraction, and provide canonical representants for classical sequent proofs modulo natural equivalences. We present the relationship between sequent proofs and proof-nets as an annotated sequent calculus, deriving formulae decorated with expansion/deletion trees. We then show a subcalculus, expansion nets, which in addition to these good properties has a polynomial-time correctness criterion.

this paper considers real-time cluster-based wireless sensor networks where the nodes harvest energy from the environment. We target performance sensitive applications that have to collectively send their information to cluster head by a predefined deadline, such as in distributed real-time monitoring and detection. the nodes are equipped with Dynamic Modulation Scaling (DMS) capable wireless radios. the problem is to determine the time slots and modulation levels that will be used by each node while communicating withthe cluster-head in order to achieve energy-neutral (perpetual) operation and maximize energy reserves. We propose a solution that adjusts underlying TDMA slots to enable high-energy nodes to transmit faster and thus produce larger slack for low-energy nodes, while meeting the performance constraint. We present an optimal mixed integer programming based solution. We also develop fast heuristics that are shown to provide approximate solutions through comprehensive experiments with actual solar energy harvesting profiles.

We present FCUBE, a theorem prover for Intuitionistic propositional logic based on a tableau calculus. the main novelty of FCUBE is that it implements several optimization techniques that allow to prune the search space acting on different aspects of proof-search. We tested the efficiency of our techniques by comparing FCUBE with other theorem provers. We found that our prover outperforms the other provers on several interesting families of formulas.

Probabilistic logicprogramming (PLP) combines logic and probability for representing and reasoning over domains with uncertainty. Hierarchical probability logicprogramming (HPLP) is a recent language of PLP whose clauses are hierarchically organized forming a deep neural network or arithmetic circuit. Inference in HPLP is done by circuit evaluation and learning is therefore cheaper than any generic PLP language. We present in this paper an Expectation Maximization algorithm, called Expectation Maximization Parameter learning for HIerarchical Probabilistic logic programs (EMPHIL), for learning HPLP parameters. the algorithm converts an arithmetic circuit into a Bayesian network and performs the belief propagation algorithm over the corresponding factor graph.

Conversion method of netlists consisting of conventional logic gates to RSFQ circuits is proposed. It treats netlists for CMOS circuits as the design entry, and converts them considering reduction of the number of clocked gates. It utilizes two characteristics of pulse logic for the reduction. One is utilizing confluence of pulses to realize logic-OR. the other is utilizing a small resettable DFF as an NIMPLY gate by tuning the order of pulse arrival. To minimize the number of clocked gates with minimum replacements of gates, the selection problem of gates for replacements utilizing those characteristics and assignment of logic level to each gate are formulated as an instance of integer linear programming.
