We present a certified declarative first-order prover with equality based on John Harrison’s Handbook of Practical Logic and Automated Reasoning, Cambridge University Press, 2009. ML code reflection is used such that the entire prover can be executed within Isabelle as a very simple interactive proof assistant. As examples we consider Pelletier’s problems 1-46.

In today’s dynamic information society, organizations critically depend on the underlying computing infrastructure. Tracking computing devices as assets and their usage helps in the provision and maintenance of an efficient, optimized service. A precise understanding of the operational infrastructure and its users also plays a key role during the negotiation of outsourcing contracts and for pla...

This paper presents an approach for categorizing documents according to their implicit locational relevance. We report a thorough evaluation of several classifiers designed for this task, built by using support vector machines with multiple alternatives for feature vectors. Experimental results show that using feature vectors that combine document terms and URL n-grams, with simple features rel...

In [5] the authors refine the well-known permutation statistic “descent” by fixing parity of (exactly) one of the descent’s numbers. In this paper, we generalize the results of [5] by studying descents according to whether the first or the second element in a descent pair is equivalent to k mod k ≥ 2. We provide either an explicit or an inclusion-exclusion type formula for the distribution of t...

This formulation of the Roy-Floyd-Warshall algorithm for the transitive closure bypasses matrices and arrays, but uses a more direct mathematical model with adjacency functions for immediate predecessors and successors. This can be implemented efficiently in functional programming languages and is particularly adequate for sparse relations.

Computations are developed for the synthesis of an FSM embedded in a known larger system such that the overall behavior satisfies a co-Büchi specification. The procedures for this are very similar to those used for regular (non-omega) automata, except for a special final step in which a set of FSM solutions is represented as a SAT instance. Each satisfying assignment corresponds to an FSM solut...

BACKGROUND To evaluate the location of tumor relapse and imaging modality for detection according to the breast cancer subtype: luminal A, luminal B, HER2 positive luminal B, nonluminal HER2 positive, and triple negative. MATERIALS AND METHODS A total of 1244 patients with breast cancer with known estrogen receptor (ER), progesterone receptor (PR), Ki-67 and human epidermal growth factor rece...

Incineration has been employed since about 1874 [6] as a method of solid waste treatment and disposal. The first incinerators were constructed in England to burn "mixed refuse" and the combustion process was initially called either "destruction" or "cremation". A prime consideration in the early development of refuse incinerators was that the heat released could be recovered for steam productio...

At first glance, pain seems relatively straightforward – hitting one’s thumb with a hammer hurts one’s thumb. Such experiences are easily understood with a structural-pathology model, which supposes pain provides an accurate indication of the state of the tissues. However, on closer inspection, pain is less straightforward. Much of the pain we see clinically fits into this less straightforward ...
