(arXiv:0901.0339v1 [cs.LO]) - We address the problem of semantic access to relational databases in the form of answering queries modulo knowledge bases using very expressive knowledge representation formalisms, such as full first-order logic or its various fragments. We propose to use a first-order logic (FOL) reasoner for computing generic answers to deductive queries, with the subsequent instantiation of these generic answers using a conventional relational DBMS. In this re...

Thoughts on an Unified Framework for Artificial Chemistries. (arXiv:0901.0318v1 [cs.AI]) - Artificial Chemistries (ACs) are symbolic chemical metaphors for the exploration of Artificial Life, with specific focus on the problem of biogenesis or the origin of life. This paper presents authors thoughts towards defining a unified framework to characterize and classify symbolic artificial chemistries by devising appropriate formalism to capture semantic and organizational information. We identify three basic high level abstractions in initi...

Experience versus Talent Shapes the Structure of the Web. (arXiv:0901.0296v1 [cs.CY]) - We use sequential large-scale crawl data to empirically investigate and validate the dynamics that underlie the evolution of the structure of the web. We find that the overall structure of the web is defined by an intricate interplay between experience or entitlement of the pages (as measured by the number of inbound hyperlinks a page already has), inherent talent or fitness of the pages (as measured by the likelihood that someone visiting the pa...

An Algorithm for File Transfer Scheduling in Grid Environments. (arXiv:0901.0291v1 [cs.NI]) - This paper addresses the data transfer scheduling problem for Grid environments, presenting a centralized scheduler developed with dynamic and adaptive features. The algorithm offers a reservation system for user transfer requests that allocates them transfer times and bandwidth, according to the network topology and the constraints the user specified for the requests. This paper presents the projects related to the data transfer field, the desig...

Offline Algorithmic Techniques for Several Content Delivery Problems in Some Restricted Types of Distributed Systems. (arXiv:0901.0290v1 [cs.DS]) - In this paper we consider several content delivery problems (broadcast and multicast, in particular) in some restricted types of distributed systems (e.g. optical Grids and wireless sensor networks with tree-like topologies). For each problem we provide efficient algorithmic techniques for computing optimal content delivery strategies. The techniques we present are offline, which means that they can be used only when full information is available...

Protecting infrastructure networks from cost-based attacks. (arXiv:0901.0349v1 [cs.NI]) - It has been known that heterogeneous networks are vulnerable to the intentional removal of a small fraction of highly connected or loaded nodes, which implies that, to protect a network effectively, a few important nodes should be allocated with more defense resources than the others. However, if too many resources are allocated to the few important nodes, the numerous less-important nodes will be less protected, which, when attacked all together...

Polarization Codes: Characterization of Exponent, Bounds, and Constructions. (arXiv:0901.0536v1 [cs.IT]) - Polarization codes were recently introduced by Ar\i kan. They achieve the capacity of arbitrary symmetric binary-input discrete memoryless channels (and even extensions thereof) under a low complexity successive decoding strategy. The original polar code construction is closely related to the recursive construction of Reed-Muller codes and is based on the $2 \times 2$ matrix $\bigl[ 1 &0 1& 1 \bigr]$. It was shown by Ar\i kan and Telatar ...

On Multipath Fading Channels at High SNR. (arXiv:0901.0521v1 [cs.IT]) - This work studies the capacity of multipath fading channels. A noncoherent channel model is considered, where neither the transmitter nor the receiver is cognizant of the realization of the path gains, but both are cognizant of their statistics. It is shown that if the delay spread is large in the sense that the variances of the path gains decay exponentially or slower, then capacity is bounded in the signal-to-noise ratio (SNR). For such channel...

Interprocedural Dataflow Analysis over Weight Domains with Infinite Descending Chains. (arXiv:0901.0501v1 [cs.DS]) - We study generalized fixed-point equations over idempotent semirings and provide an efficient algorithm for the detection whether a sequence of Kleene's iterations stabilizes after a finite number of steps. Previously known approaches considered only bounded semirings where there are no infinite descending chains. The main novelty of our work is that we deal with semirings without the boundedness restriction. Our study is motivated by several app...

The return probability as a function of time as well as the distribution of time intervals between consecutive visits are measured and found to be independent of the level of activity of single users. The results indicate a rich variety of individual behaviors and seem to preclude the possibility of d...

Transmission Capacities for Overlaid Wireless Ad Hoc Networks with Outage Constraints. (arXiv:0901.0492v1 [cs.IT]) - We study the transmission capacities of two coexisting wireless networks (a primary network vs. a secondary network) that operate in the same geographic region and share the same spectrum. We define transmission capacity as the product among the density of transmissions, the transmission rate, and the successful transmission probability (1 minus the outage probability). The primary (PR) network has a higher priority to access the spectrum without...

Highly Undecidable Problems For Infinite Computations.

In particular, the universality problem, the inclusion problem, the equivalence problem, the determinizability problem, the complementability problem, and the unambiguity problem are all $\Pi_2^...

Forbidden Information. (arXiv:cs/0203029v11 [cs.CC] UPDATED) - There appears to be a loophole in Goedel Incompleteness Theorem, vaguely perceived for a long time but not clearly identified.

Similar problems and answers apply to other unsolvability results for tasks allowing non-unique solutions, e.g. non-recursive tilings. The tec...

Convergence and Monotonicity Problems in an Information-Theoretic Law of Small Numbers. (arXiv:0810.5203v2 [cs.IT] UPDATED) - A version of the law of small numbers is analyzed in information-theoretic terms. Specifically, let $f=\{f_i, i=0, 1, \}$ be a probability mass function (pmf) on nonnegative integers with mean $\lambda<\infty$. Denote the $n$th convolution of $f$ by $f^{*n}$ and denote the $\alpha$-thinning of $f$ by $T_\alpha(f)$. Then, as $n\to\infty$, the entropy $H(T_{1/n}(f^{*n}))$ tends to $H(po(\lambda))$, where $po(\lambda)$ denotes the pmf of the Pois...

Camera distortion self-calibration using the plumb-line constraint and minimal Hough entropy. (arXiv:0810.4426v2 [cs.CV] UPDATED) - In this paper we present a simple and robust method for self-correction of camera distortion using single images of scenes which contain straight lines. Since the most common distortion can be modelled as radial distortion, we illustrate the method using the Harris radial distortion model, but the method is applicable to any distortion model. The method is based on transforming the edgels of the distorted image to a 1-D angular Hough space, and o...

How to Fully Exploit the Degrees of Freedom in the Downlink of MISO Systems With Opportunistic Beamforming. (arXiv:0809.0536v2 [cs.IT] UPDATED) - The opportunistic beamforming in the downlink of multiple-input single-output (MISO) systems forms $N$ transmit beams, usually, no more than the number of transmit antennas $N_t$. However, the degrees of freedom in this downlink is as large as $N_t^2$. That is, at most $N_t^2$ rather than only $N_t$ users can be simultaneously transmitted and thus the scheduling latency can be significantly reduced. In this paper, we focus on the opportunistic be...

The channel state information (CSI) on the link of the SU is assumed to be perfectly known at the SU transmitter (SU-Tx). However, due to loose cooperation between the SU and the PU, only partial CSI o...

In a typical communications system a cryptographic application is run at a layer above the physical layer and assumes the channel is error free. However, in any real application the channels for friendly users and passive eavesdroppers are not error free and Wyner's wiretap model addresses this scenario. Using this model, we ...
