Methods and Approaches for Real-Time Hierarchical Motion Detection

Publisher: name: Columbia University
Year: 1988
Subjects: Computer science

description: The recent work on perception and measurement of visual motion has consistently advocated the use of a hierarchical representation and analysis. In most of the practical applications of motion perception it is absolutely necessary to be able to construct and process these hierarchical image representations in real-time. First, we discuss a simple scheme for coarse motion detection that highlights the capabilities of the PIPE image processor, showing its ability to work in both the spatial and temporal dimensions in real-time. Secondly, we show how this architecture can be used to build pyramid structures useful for motion detection, again emphasizing the real-time nature of the computations. Using the PIPE architecture, we have constructed a Pyramid of Oriented Edges (POE) which is a logical extension of Burt's pyramid and also a version of Mallat's pyramid. The results of these algorithms are available on a video tape to highlight their real-time performance on moving images. Third, we propose a new method using PIPE that will allow dense optic flow computation and which relates the intensity-correlation and spatio-temporal frequency based methods of determining optic flow.

description: The measurement of electron temperatures and metallicities in H ii regions and Planetary Nebulae (PNe) has-for several decades-presented a problem: results obtained using different techniques disagree. What it worse, they disagree consistently. There have been numerous attempts to explain these discrepancies, but none has provided a satisfactory solution to the problem. In this paper, we explore the possibility that electrons in H ii regions and PNe depart from a Maxwell-Boltzmann equilibrium energy distribution. We adopt a "kappa-distribution" for the electron energies. Such distributions are widely found in Solar System plasmas, where they can be directly measured. This simple assumption is able to explain the temperature and metallicity discrepancies in H ii regions and PNe arising from the different measurement techniques. We find that the energy distribution does not need to depart dramatically from an equilibrium distribution. From an examination of data from Hii regions and PNe it appears that kappa ~ 10 is sufficient to encompass nearly all objects. We argue that the kappa-distribution offers an important new insight into the physics of gaseous nebulae, both in the Milky Way and elsewhere, and one that promises significantly more accurate estimates of temperature and metallicity in these regions.

Fast Fourier Transforms: A Review
Creators: name: Wolberg, George
Publisher: name: Columbia University
Year: 1988
Subjects: Computer science

description: The purpose of this paper is to provide a detailed review of the Fast Fourier Transform. Some familiarity with the basic concepts of the Fourier Transform is assumed. The review begins with a definition of the discrete Fourier Transform (DFT) in section 1. Directly evaluating the DFT is demonstrated there to be an 0 (N2) process. The efficient approach for evaluating the OFT is through the use of FFT algorithms. Their existence became generally known in the mid-1960s, stemming from the work of J. W. Cooley and J. W. Tukey. Although they pioneered new FFT algorithms, the original work was actually discovered over 20 years earlier by Danielson and Lanczos. Their formulation, known as the Danielson-Lanczos Lemma, is derived in section 2. Their recursive solution is shown to reduce the computational complexity to 0 (N log2 N). A modification of that method, the Cooley-Tukey algorithm, is given in section 3. Yet another variation, the Cooley-Sande algorithm, is described in section 4. These last two techniques are also known in the literature as the decimation-in-time and decimation-in-frequency algorithms. respectively. Finally, source code, written in C, is provided in the appendix.

description: Text documents often contain valuable structured data that is hidden in regular English sentences. This data is best exploited if available as a relational table that we could use for answering precise queries or for running data mining tasks. Our Snowball system extracts these relations from document collections starting with only a handful of user-provided example tuples. Based on these tuples, Snowball generates patterns that are used, in turn, to find more tuples. In this paper we introduce a new pattern and tuple generation scheme for Snowball, with different strengths and weaknesses than those of our original system. We also show preliminary results on how we can combine the two versions of Snowball to extract tuples more accurately.
A Lower Bound for the Sturm-Liouville Eigenvalue Problem on a Quantum Computer
Creators: name: Bessen, Arvid J.
Publisher: name: Columbia University
Year: 2005
Subjects: Computer science

description: We study the complexity of approximating the smallest eigenvalue of a univariate Sturm-Liouville problem on a quantum computer. This general problem includes the special case of solving a one-dimensional Schroedinger equation with a given potential for the ground state energy. The Sturm-Liouville problem depends on a function q, which, in the case of the Schroedinger equation, can be identified with the potential function V. Recently Papageorgiou and Wozniakowski proved that quantum computers achieve an exponential reduction in the number of queries over the number needed in the classical worst-case and randomized settings for smooth functions q. Their method uses the (discretized) unitary propagator and arbitrary powers of it as a query ('power queries'). They showed that the Sturm-Liouville equation can be solved with O(log(1/e)) power queries, while the number of queries in the worst-case and randomized settings on a classical computer is polynomial in 1/e. This proves that a quantum computer with power queries achieves an exponential reduction in the number of queries compared to a classical computer. In this paper we show that the number of queries in Papageorgiou's and Wozniakowski's algorithm is asymptotically optimal. In particular we prove a matching lower bound of log(1/e) power queries, therefore showing that log(1/e) power queries are sufficient and necessary. Our proof is based on a frequency analysis technique, which examines the probability distribution of the final state of a quantum algorithm and the dependence of its Fourier transform on the input.
The Semi-Automatic Generation of Processing Element Control Paths for Highly Parallel Machines

description: This paper describes a recently implemented program that very rapidly generates control paths for different variants of the constituent processing elements of a particular massively parallel machine, the NON-VON Supercomputer. The program, called PLATO, accepts as input a set of instruction opcodes, together with associated control information, and produces as output a functionally correct, highly area-efficient set of PLA's for the processing elements. One novel aspect of the program is its use of a channel routing algorithm to generate a Weinberger Array layout for the OR-plane of the PLA. By supporting extremely rapid generation of processing elements with different instruction sets, PLATO facilitates "rapid turnaround" architectural experimentation of a sort that would otherwise be impractical. Use of the program has already yielded major area and performance improvements in the NON-VON processing element. Many of the techniques employed in the PLATO system should prove applicable to the semi-automatic layout of processing elements for other multiprocessor machines.

Incremental Evaluation of Ordered Attribute Grammars for Asynchronous Subtree Replacements
Creators: name: Micallef, Josephine
Publisher: name: Columbia University
Year: 1988
Subjects: Computer science

description: Incremental algorithms for evaluating attribute grammars (AGs) have been extensively studied in recent years, primarily because of their application in language-based environments. Ordered attribute grammars are a subclass of AGs for which efficient evaluators can be constructed. Previous incremental algorithms for ordered attribute grammars only allowed one modification to the program at a time, requiring attribute evaluation due to one change to quiesce before another one due to a second change can start. This article presents new incremental evaluation algorithms for ordered attribute grammars that can handle asynchronous program modifications in an optimal manner. Support for asynchronous changes is necessary in environments for multiple users, where different programmers may be making changes to different parts of the program simultaneously. The key to the optimality of the algorithm is an ordering of the attribute evaluations so that an attribute affected by more than one change will only be evaluated once if the changes happen concurrently.
Session-Aware Popularity-based Resource Allocation Across Several Differentiated Service Domains

description: The Differentiated Services model (DS) maps traffic into network services that have different quality levels. However, inside each service flows can be treated unfairly, since the DS model has no policy to distribute the service bandwidth between all sessions that compose the service aggregate traffic. Our goal is to study a signaling protocol that fairly distributes the resources reserved for each DS service between scalable multimedia sessions in a multicast network environment, where scalable sources divide session traffic in hierarchical layers, sending each layer to different multicast groups. We present a signaling protocol called Session-Aware Popularity Resource Allocation (SAPRA) that allows the distribution of DS services resources along sessions path, based upon the receiver population of each session. Simulations show that SAPRA protocol has small bandwidth overhead, is efficient updating the resources allocated to each session and also supplying receivers with reports about the quality level of their session.
Proteomic analysis of Salmonella-host interactions reveals novel host targets of SopB
Creators: name: Rogers, Lindsay Deborah
Publisher: name: University of British Columbia
Year: 2011

description: Salmonella enterica is an intracellular bacterium causing gastroenteritis and typhoid fever. Virulence is achieved by two type III secretion systems (T3SS) encoded on Salmonella pathogenicity islands 1 and 2 (SPI-1 and SPI-2) that translocate effector proteins into host cells where they mimic or block host protein function. Effectors translocated by T3SS-1 facilitate internalization of the bacteria into the Salmonella-containing vacuole (SCV), actively stimulate intracellular signaling cascades, and regulate trafficking of the SCV to avoid degradation. A T3SS-1 effector, SopB has been shown to regulate a vast array of host processes important for pathogenesis, but only a few host proteins have been identified as targets of this effector. Here quantitative mass spectrometry-based proteomics and bioinformatics techniques have been employed to identify novel host targets of SopB. Quantitative immunoprecipitation experiments identified Cell division control protein 42 (Cdc42) as a direct SopB binding partner, and the binding site within SopB was localized to residues 117-168. SopB and active Cdc42 were shown to colocalize at membrane ruffles on the host cell surface, and two SopB monoubiquitylation sites were identified. To globally analyze host protein phosphorylation events regulated by SopB, a phosphoproteomics method employing heat and chaotropic denaturation for phosphatase inactivation, peptide fractionation by in-solution isoelectric focusing, and phosphopeptide enrichment by metal oxide chromatography was developed. Quantitative analysis of host protein phosphorylation during the initial 20 minutes post Salmonella infection identified >9000 phosphorylation sites, >2000 of which were dynamic. Signaling cascades downstream of T3SS-1 were compared to those induced by growth factor simulation, revealing stark differences between these signaling mechanisms. Kinase prediction upstream of dynamic phosphosites revealed protein kinases B and C as master host regulators during Salmonella infection, and phosphorylation dynamics following wild type versus ΔsopB infection were compared to identify novel host targets of SopB. This work has greatly improved our understanding of SopB’s activity within host cells. It has also provided the first global view of host protein phosphorylation dynamics during bacterial infection, and developed several techniques that can be widely applied within the field of pathogen-host interactions.
Tool Extension in an ALOE Editor

description: Many approaches to tool integration can be seen as variations on two models, the "sequential: and "concurrent." "Sequential" models are characterized by a high degree of modularity. In this model, tools execute in sequence and work on separate data structures. "Concurrent" models are characterized by the ability to interleave the execution of various tools. Here, tools work on a common data structure. This thesis describes AMPE (A Manufacturing Programming Environment) which consists of two tools integrated in a way that has advantages from both models. The execution of both tools can be interleaved, but they use separate data structures and maintain a degree of modularity. AMPE consists of an ALOE structure editor, which has been extended to work with an interpreter for the programming language, AML/X. The two tools run as separate processes and communicate through message passing.

description: The structural parameters with stability upon Si incorporation and elastic, electronic, thermodynamic and optical properties of Ti3Al1-xSixC2 (0 \leq x \leq 1) are investigated systematically by the plane wave psedudopotential method based on the density functional theory (DFT). The increase of some elastic parameters with increasing Si-content renders the alloys to possess higher compressive and tensile strength. The Vickers hardness value obtained with the help of Mulliken population analysis increases as x is increased from 0 to 1. The solid solutions considered are all metallic with valence and conduction bands, which have a mainly Ti 3d character, crossing the Fermi level. The temperature and pressure dependences of bulk modulus, normalized volume, specific heats, thermal expansion coefficient, and Debye temperature are all obtained through the quasi-harmonic Debye model with phononic effects for T = 0-1000K and P = 0-50GPa. The obtained results are compared with other results where available. Further an analysis of optical functions for two polarization vectors reveals that the reflectivity is high in the visible-ultraviolet region up to ~ 10.5 eV region showing promise as good coating material.

description: Intrusion detection systems need to maximize security while minimizing costs. In this paper, we study the problem of building cost-sensitive intrusion detection models. We examine the major cost factors: development costs, operational costs, damage costs incurred due to intrusions, and the costs involved in responding to intrusions. We propose cost-sensitive machine learning techniques to produce models that are optimized for user-defined cost metrics. We describe an automated approach for generating efficient run-time versions of these models. Empirical experiments in off-line analysis and real-time detection show that our cost-sensitive modeling and deployment techniques are effective in reducing the overall cost of intrusion detection.

description: The proplem of sound propagation in an oceanic waveguide is considered. Scattering on random inhomogeneity of the waveguide leads to wave chaos. Chaos reveals itself in spectral properties of the finite-range evolution operator (FREO). FREO describes transformation of a wavefield in course of propagation along a finite segment of a waveguide. We study transition to chaos by tracking variations in spectral statistics with increasing length of the segment. Analysis of the FREO is accompanied with ray calculations using the one-step Poincaré map which is the classical counterpart of the FREO. Underwater sound channel in the Sea of Japan is taken for an example. Several methods of spectral analysis are utilized. In particular, we approximate level spacing statistics by means of the Berry-Robnik and Brody distributions, explore the spectrum using the procedure elaborated by A. Relano with coworkers (Relano et al, Phys. Rev. Lett., 2002; Relano, Phys. Rev. Lett., 2008), and analyze modal expansions of the eigenfunctions. We show that the analysis of FREO eigenfunctions is more informative than the analysis of eigenvalue statistics. It is found that near-axial sound propagation in the Sea of Japan preserves stability even over distances of hundreds kilometers. This phenomenon is associated with the presence of a shearless torus in the classical phase space. Increasing of acoustic wavelength degrades scattering, resulting in recovery of localization near periodic orbits of the one-step Poincaré map. Relying upon the formal analogy between wave and quantum chaos, we suggest that the concept of FREO, supported by classical calculations via the one-step Poincaré map, can be efficiently applied for studying chaos-induced decoherence in quantum systems.

description: The Programming Systems Lab at Columbia University has investigated software process modeling and enactment since its inception in the mid-1980s, initially in the Marvel project. In the early to mid-90s, we extended to cross-organizational processes operating over the Internet, in Oz and OzWeb. The successive prototype frameworks we developed and demonstrated were used on a daily basis in-house to maintain, deploy and monitor their own components, APIs and user interfaces. The new process technology first presented here is broadly based on our decade of research on and experimentation with architecting and using such prototype services and software development processes targeted to Internet/Web middleware and applications, but reflects a major departure from our own (and others') previous directions. In particular, current process and workflow systems, including our own, are often too rigid for open-ended creative intellectual work, unable to rapidly adapt either the models or the enactment to situational context and/or user role. On the other hand, the process/workflow ideal implies a flexible mechanism for composition and coordination of information system components. We now present our in-progress development of rehostable lightweight mobile agents for on-the-fly process construction, adaptation and evolution, system reconfiguration, and knowledge propagation.

description: Medical students are a vulnerable group for harmful health behaviours due to academic stress. Increased screen time is associated with adverse health behaviour, particularly delayed bedtime, shorter sleep duration and poorer sleep quality. This possible relationship has not yet been examined among medical students in Europe. Medical students at the Technical University of Dresden were invited to participate in an online questionnaire based cross-sectional study. To analyse correlations between screen time and sleep parameters, correlation coefficients, linear regression and mixed-model analysis were calculated. 415 students (average age 24 years, 70% female) were included in the analysis. The students reported an average of 7 h screen time per day and 7.25 h sleep duration per night. Approximately 23% (n = 97) reported sleeping less than 7 h per night and 25% (n = 105) reported fairly to very poor sleep quality. Students who reported more screen time for leisure went to bed significantly later (r = 0.213, p < 0.001). Students who spent more screen time for study/work tended to sleep shorter (r = − 0.108, p < 0.015). There was no significant association between screen time and sleep quality (p = 0.103). The results show a need for educational interventions to promote healthy sleep behaviour and to limit screen time.

description: We study the problem of appropriately generating connectives (e.g., 'but', 'because', 'since', 'however') in a discourse. We claim that connectives operate at the discourse level rather than the semantic level, and that they indicate pragmatic features of the units they connect. Therefore, in order to choose the appropriate connective, a surface generator must find in its input a set of pragmatic features that affect or are affected by the choice of a connective. We present such a set of features and show their role in a variety of examples of the connective 'but'.

description: Crep is a UNIX2 tool which searches either a tagged or free textual corpus file and outputs each sentence that matches the specified regular expression provided by the user as a parameter. The expression consists of user-defined regular expressions of words and/or part-of-speech tags. The purpose of crep is to make the searches faster and easier than by either a) searching through corpora by hand; or b) constructing a lexical scanner for each specific search. crep achieves this facilitation by offering the user a simple expression syntax, from which it automatically constructs an appropriate scanner. The user therefore has the ability to execute a whole search in one command, invoking implicitly and explicitly several tools, including a sentence delimiter, a part of speech tagger (developed by Ken Church at AT&T Bell Laboratories), and various output filters.

description: A quantitative model of abstraction in problem solving is presented which explains how and to what extent it reduces the amount of search necessary to solve a problem. It is shown that a single level of abstraction can reduce search time by a factor of the square root of the size of the original space. Multiple hierarchical levels of abstraction can reduce the search complexity of a problem from linear in the size of the original problem space to logarithmic.

description: The attractiveness of the Italian economy for inward foreign direct investment (IFDI) has been traditionally limited, despite the country's locational advantages such as a large domestic market and a skilled labor force. The recent global crisis worsened the country's IFDI position, with flows falling from US$ 40 billion in 2007 to US$ 11 billion in 2008 before recovering to US$ 20 billion in 2009 but down again to US$ 9 billion in 2010. Although the country's IFDI stock had grown since 2000 at a rate similar to that of the European Union as a whole, in 2010 IFDI stock contracted vis-à -vis 2009, reflecting how Italy, compared to other key European countries and to its own potential, continues to underperform. The main obstacles to exploiting the country's potential for IFDI lie both in the largely insufficient actions undertaken to attract and promote IFDI, and especially in the lack of coordination with other relevant policy measures (e.g. infrastructure development) within a broader framework aimed at regional and national development.

description: LPS is a Logic Programming System currently under development and specifically targeted for implementation on massively parallel architectures. We present a detailed explanation of algorithms under development for parallel execution of LPS programs. The explanation is significantly more detailed than those published previously. An abstract proof procedure is developed which encompasses these algorithms and several variants, as well as the standard sequential Prolog algorithm. This abstract procedure provides a conceptual basis for our discussion and. in a companion paper, for a critical analysis of various execution strategies. The algorithms have been successfully implemented and demonstrated in simulation on a number of small programs. Work is currently underway to transfer this implementation to a working prototype machine based on the DADO parallel architecture. Due to the depth of our treatment we assume that the reader has read previously published literature in the area.

description: Decaying active region 10942 is investigated from 4:00-16:00 UT on February 24, 2007 using a suite of EUV observing instruments. Results from Hinode/EIS, STEREO and TRACE show that although the active region has decayed and no sunspot is present, the physical mechanisms that produce distinguishable loop structures, spectral line broadening, and plasma flows still occur. A coronal loop that appears as a blue-shifted structure in Doppler maps is apparent in intensity images of log(T) = 6.0-6.3 ions. The loop structure is found to be anti-correlated with spectral line broadening generally attributed to nonthermal velocities. This coronal loop structure is investigated physically (temperature, density, geometry) and temporally. Lightcurves created from imaging instruments show brightening and dimming of the loop structure on two different time scales; short pulses of 10-20 min and long duration dimming of 2-4 hours until its disappearance. The coronal loop structure, formed from relatively blue-shifted material that is anti-correlated with spectral line broadening, shows a density of 10^10 to 10^9.3 cm-3 and is visible for longer than characteristic cooling times. The maximum nonthermal spectral line broadenings are found to be adjacent to the footpoint of the coronal loop structure.

Implementing Activity Structures Process Modeling On Top Of The MARVEL Environment Kernel

Year: 1991

description: Our goal was to implement the activity structures model defined by Software Design & Analysis on top of the MARVEL environment kernel. This involved further design of the activity structures process definition language and enaction model as well as translation and run-time support in terms of facilities provided by MARVEL. The result is an elegant declarative control language for multi-user software processes, with data and activities defined as classes and rules in the previously existing MARVEL Strategy Language. Semantics-based concurrency control is provided by a combination of the MARVEL kernel‘s lock and transaction managers and the send/receive synchronization primitives of the activity structures model.

A Survey of Process Migration Mechanisms
Creators: name: Smith, Jonathan M.
Publisher: name: Columbia University
Year: 1988
Subjects: Computer science

description: We define process migration as the transfer of a sufficient amount of a process's state from one machine to another for the process to execute on the target machine. This paper surveys proposed and implemented mechanisms for process migration. We pay particular attention to the designer's goals, such as performance, load-balancing, and reliability. The effect of operating system design upon the ease of implementation is discussed in some detail; we conclude that message-passing systems simplify designs for migration.

Solving the Depth Interpolation Problem on a Parallel Architecture with Efficient Numerica1 Methods
Creators: name: Choi, Dong Jae
Publisher: name: Columbia University
Year: 1988
Subjects: Computer science

description: Many constraint propagation problems in early vision, including depth interpolation, can be cast as solving a large system of linear equations where the resulting matrix is symmetric and positive definite (SPD). Usually ï¼Œthe resulting SPD matrix is sparse. We solve the depth interpolation problem on a parallel architecture, a fine grained SIMD machine with local and global communication networks. We show how the Chebyshev acceleration and the conjugate gradient methods can be run on this parallel architecture for sparse SPD matrices. Using an abstract SIMD model, for several synthetic and real images we show that the adaptive Chebyshev acceleration method executes faster than the conjugate gradient method, when given near optimal initial estimates of the smallest and largest eigenvalues of the iteration matrix. We extend these iterative methods through a multigrid approach, with a fixed multilevel coordination strategy. We show again that the adaptive Chebyshev acceleration method executes faster than the conjugate gradient method, when accelerated further with the multigrid approach. Furthermore, we show that the optimal Chebyshev acceleration method performs best since this method requires local computations only, whereas the adaptive Chebyshev acceleration and the conjugate gradient methods require both local and global computations.
Regularization: Problems and Promises
Creators: name: Boult, Terrance E.
Publisher: name: Columbia University
Year: 1988
Subjects: Computer science

description: Regularization is becoming a popular framework for describing and solving many ill-posed problems of computer vision. Of course, a generalized framework is only useful if it provides additional insights or benefits unavailable without it. This paper discusses some of the benefits promised by the regularization framework. Additionally, as a mathematical paradigm for vision, regularization presents many difficulties for the vision researcher, and some of these difficulties are discussed in this paper. The paper then discusses the lack of development of most of the "promises of regularization" theory, and gives a. brief look as some of the promises which have been realized. In the context of smooth surface reconstruction, the paper addresses one of the most difficult problems with the use of regularization: the problem of determining an appropriate functional class, norm, and regularization stabilizing functional. In particular, results are discussed from an experiment which subjectively orders various functional classes and stabilizing functionals for a regularization-based formulation of the surface reconstruction problem. The conclusions drawn include the fact that there exist non-traditional formulations of this regularization problem which provide better results. The paper concludes with a brief mention of two more general frameworks and their relationship to regularization.

description: Multiple economic, ecological, institutional and societal challenges raise concern about the future functionality of agriculture and more specifically of farms in Europe, which leads to an increased need to understand and improve its resilience. We aim to provide a comprehensive overview of farmers’ perception and self-assessment of resilience that would serve as a solid basis for further research on farm resilience. In order to achieve the aim, a farmer survey was designed based on theories of risk communication, decision theory and psychometric models. We conducted the survey in 11 case study regions across the European Union. No previous empirical research on farm resilience included so many diverse case studies.
