Real-Time Straight-Line Detection for XGA-Size Videos by Hough Transform with Parallelized Voting Procedures

The Hough Transform (HT) is a method for extracting straight lines from an edge image. The main limitations of the HT for usage in actual applications are computation time and storage requirements. This paper reports a hardware architecture for HT implementation on a Field Programmable Gate Array (FPGA) with parallelized voting procedure. The 2-dimensional accumulator array, namely the Hough space in parametric form (ρ, θ), for computing the strength of each line by a voting mechanism is mapped on a 1-dimensional array with regular increments of θ. Then, this Hough space is divided into a number of parallel parts. The computation of (ρ, θ) for the edge pixels and the voting procedure for straight-line determination are therefore executable in parallel. In addition, a synchronized initialization for the Hough space further increases the speed of straight-line detection, so that XGA video processing becomes possible. The designed prototype system has been synthesized on a DE4 platform with a Stratix-IV FPGA device. In the application of road-lane detection, the average processing speed of this HT implementation is 5.4 ms per XGA-frame at 200 MHz working frequency.
Human Treponema pallidum 11q/j isolate belongs to subsp. endemicum but contains two loci with a sequence in TP0548 and TP0488 similar to subsp. pertenue and subsp. pallidum, respectively

Background Treponema pallidum subsp. endemicum (TEN) is the causative agent of endemic syphilis (bejel). An unusual human TEN 11q/j isolate was obtained from a syphilis-like primary genital lesion from a patient that returned to France from Pakistan. Methodology/Principal findings The TEN 11q/j isolate was characterized using nested PCR followed by Sanger sequencing and/or direct Illumina sequencing. Altogether, 44 chromosomal regions were analyzed. Overall, the 11q/j isolate clustered with TEN strains Bosnia A and Iraq B as expected from previous TEN classification of the 11q/j isolate. However, the 11q/j sequence in a 505 bp-long region at the TP0488 locus was similar to Treponema pallidum subsp. pallidum (TPA) strains, but not to TEN Bosnia A and Iraq B sequences, suggesting a recombination event at this locus. Similarly, the 11q/j sequence in a 613 bp-long region at the TP0548 locus was similar to Treponema pallidum subsp. pertenue (TPE) strains, but not to TEN sequences. Conclusions/Significance A detailed analysis of two recombinant loci found in the 11q/j clinical isolate revealed that the recombination event occurred just once, in the TP0488, with the donor sequence originating from a TPA strain. Since TEN Bosnia A and Iraq B were found to contain TPA-like sequences at the TP0548 locus, the recombination at TP0548 took place in a treponeme that was an ancestor to both TEN Bosnia A and Iraq B. The sequence of 11q/j isolate in TP0548 represents an ancestral TEN sequence that is similar to yaws-causing treponemes. In addition to the importance of the 11q/j isolate for reconstruction of the TEN phylogeny, this case emphasizes the possible role of TEN strains in development of syphilis-like lesions.
Globalisation and Labour Demand Elasticities in Britain

Do multinational firms exhibit different patterns of labor demand from purely domestic firms? Many standard models of trade and multinational companies suggest such differences. We examine this question using a plant-level panel covering U.K. manufacturing from 1973 through 1992, where we can distinguish U.K.-headquartered multinationals, foreign-owned multinationals, and domestic U.K. firms. Across these three ownership groups we look for differences both on the intensive margin, in terms of labor-demand elasticities, and on the extensive margin, in terms of plant shutdowns. For our sample period we estimate that both groups of multinational plants had larger increases than did domestic plants in the elasticity of demand for production labor. These increases were driven largely by greater substitutability between production labor and materials. We also estimate that both types of multinational plants are more likely to shut down than domestic plants are, conditional on a set of operational advantages enjoyed by multinationals that make them less likely to shut down.
Gamma‐aminobutyric acid in ganglia and in single neurons from Aplysia and lobster

SOME OF the most compelling evidence that GABA is an inhibitory neurotransmitter has been obtained with invertebrate preparations (among the more recent reviews are: OTSUKA, 1972; GERSCHENFELD, 1973; DAVIDSON, 1976; ROBERTS et al., 1976; KEHOE & MARDER, 1976). In crustaceans GABA mimics the action of inhibitory nerve stimulation at the neuromuscular junction and at other synapses. It is much more highly concentrated in inhibitory axons than in excitatory axons and is released from inhibitory axons upon stimulation (KRAVITZ et al., 1963; KRAVITZ & POTTER, 1965; OTSUKA et al., 1966). In the lobster biochemical data supplements physiological evidence that GABA is the transmitter of inhibitory neurons. Isolated, inhibitory neurons in the abdominal ganglia, 11, I , and I,, were shown to contain large amounts of GABA (more than 20 pmol/nebron) while the amount in excitatory neurons was below the detection limits of the assay (OTSUKA et al., 1967). In molluscs, the evidence for GABA as a neurotransmitter is less direct and less complete. GABA applied directly to individual neurons of Aplysia produced specific hyperpolarizing or depolarizing responses, indicating the presence of different kinds of receptors on various soma (YAROWSKY & CARPENTER, 1977). A Naf-dependent uptake system has also been studied; however, the labelled GABA taken up during the incubation appeared predominantly in extra-neuronal rather than in neuronal sites (ZEMAN et al., 1975). Direct chemical measurements of GABA in individual neurons have not provided support for its role as a neurotransmitter since it was found in all neurons tested. COTTRELL (1974) used a dansyl procedure to detect GABA, while ZEMAN & CARPENTER (1975) used an enzymatic (GABase) procedure and reported that even those neurons identified physiologically either as cholinergic (e.g. L I 1 ) or as serotoninergic (e.g. C,) contained large amounts (1&500 pmol/neuron). Separate studies of GABA levels in Aplysia ganglia using the GABase procedure have given different results. ZEMAN & CARPENTER (1975) found GABA distributed uniformly among the various ganglia. KURODA & OKADA (1977), on the other hand, reported significantly lower values for all ganglia and marked differences between ganglia. In this assay NADPH generated from GABA in the presence of
Research on Vibration Grinding Deburring and Finishing Process

In mechanical manufacturing, the traditional methods adopted for deburring and finishing is not only high labor intensity, but also difficult to reach the surface roughness and requirements. The vibration grinding deburring and finishing process method is put forward, and the removal of micro hole drilling burr and surface finishing experiments are carried. It can be seen from the experimental results that the vibration grinding process method can thoroughly remove burr and get the finishing effect. The vibration grinding system has the features of low cost and brief operation. The vibration grinding new process method has high practical value.
Ultrafast laser inscribed integrated photonics: material science to device development

Detailed studies of intense light – material interactions has led to new insights into fs laser induced refractive index change in a range of glass types. This body of knowledge enables the development of advanced processing methodologies, resulting in novel planar and 3D guided wave devices. We will review the chemistry and morphology associated with fs laser induced refractive index change in multi-component glasses such as ZBLAN, phosphates and silicates, and discuss how these material changes inform our research programs developing a range of active and passive lightwave systems.
Iterative Multi-document Neural Attention for Multiple Answer Prediction

People have information needs of varying complexity, which can be solved by an intelligent agent able to answer questions formulated in a proper way, eventually considering user context and preferences. In a scenario in which the user profile can be considered as a question, intelligent agents able to answer questions can be used to find the most relevant answers for a given user. In this work we propose a novel model based on Artificial Neural Networks to answer questions with multiple answers by exploiting multiple facts retrieved from a knowledge base. The model is evaluated on the factoid Question Answering and top-n recommendation tasks of the bAbI Movie Dialog dataset. After assessing the performance of the model on both tasks, we try to define the long-term goal of a conversational recommender system able to interact using natural language and to support users in their information seeking processes in a personalized way.
imultaneous high-Q confinement and selective direct piezoelectric xcitation of flexural and extensional lateral vibrations in a silicon phononic rystal slab resonator

The complete phononic band gap (PnBG) of a phononic crystal (PnC) slab is used to efficiently and simultaneously confine both flexural and extensional (longitudinal) elastic vibrations in a resonator. The PnC structure is fabricated by etching a hexagonal (honeycomb) array of air holes in a silicon (Si) slab. Flexural and extensional acoustic modes in the structure are directly excited by a piezoelectric transducer stack fabricated directly on top of the resonant structure to excite the desired modes. Using a frequency sweep analysis, it is shown that the modes of the structure can be selectively excited by modification of the trans-
Speed-Sensorless AC Drives With the Rotor Time Constant Parameter Update

This paper presents a new technique for online identification of an induction motor rotor time constant. The technique is designed for a shaft-sensorless indirect field-oriented control induction motor drive with a model reference adaptive system (MRAS)-based speed estimator. The MRAS estimator is sensitive to the changes in the rotor time constant, and online identification of that parameter is essential. If rotor parameter error exists, it does not only change the achieved rotor speed, but it also changes the dynamic behavior of the whole field control and speed estimation structure. The proposed rotor parameter update is exactly based on the newly introduced dynamic model of the potentially detuned MRAS-based speed estimator. The technique avoids the use of test signals and rather extracts the needed information from the ever-present signal jitter, which is inherent to the current and speed servo loops. This paper demonstrates that the phase angle difference between some spectral components of selected small signals within the speed estimator can be used for rotor parameter update. Computer simulations and experiments are performed under a variety of conditions to validate the effectiveness of the proposed rotor parameter update technique.
A case for economy grid architecture for service oriented grid computing

Computational Grids are a promising platform for executinglarge-scale resource intensive applications. However, resource management and scheduling in the Grid environment is a complex undertaking as resources are (geographically) distributed, heterogeneous in nature, owned by different individuals or organizations with their own policies, have different access and cost models, and have dynamically varying loads and availability. This introduces a number of challenging issues such as site autonomy, heterogeneous interaction, policy extensibility, resource allocation or co-allocation, online control, scalability, transparency, resource brokering, and "computational economy". A number of Grid systems (such as Globus and Legion)have addressed many of these issues with exception of acomputational economy. We argue that a computationaleconomy is required in order to create a real world scalableGrid because it provides a mechanism for regulating the Gridresources demand and supply. It offers incentive for resourceowners to be part of the Grid and encourages consumers tooptimally utilize resources and balance timeframe and accesscosts. We propose a 'computational economy framework' thatbuilds on the existing Grid middleware systems and offers aninfrastructure for resource management and trading in theGrid environment. We discuss the usage economic models forresource trading in the Nimrod/G resource broker and presentdeadline and cost-based scheduling experimental results onthe Grid.
Recovering a Hidden Community Beyond the Spectral Limit in O(|E|log*|V|) Time

The stochastic block model for one community with parameters $n, K, p,$ and $q$ is considered: $K$ out of $n$ vertices are in the community; two vertices are connected by an edge with probability $p$ if they are both in the community and with probability $q$ otherwise, where $p > q > 0$ and $p/q$ is assumed to be bounded. An estimator based on observation of the graph $G=(V,E)$ is said to achieve weak recovery if the mean number of misclassified vertices is $o(K)$ as $n \to \infty$. A critical role is played by the effective signal-to-noise ratio $\lambda=K^2(p-q)^2/((n-K)q). $ In the regime $K=\Theta(n)$, a na\"{i}ve degree-thresholding algorithm achieves weak recovery in $O(|E|)$ time if $\lambda \to \infty$, which coincides with the information theoretic possibility of weak recovery. The main focus of the paper is on weak recovery in the sublinear regime $K=o(n)$ and $np = n^{o(1)}. $ It is shown that weak recovery is provided by a belief propagation algorithm running for $\log^\ast(n)+O(1) $ iterations, if $\lambda > 1/e,$ with the total time complexity $O(|E| \log^*n)$. Conversely, no local algorithm with radius $t$ of interaction satisfying $t = o(\frac{\log n}{\log(2+np)})$ can asymptotically outperform trivial random guessing if $\lambda \leq 1/e. $ By analyzing a linear message-passing algorithm that corresponds to applying power iteration to the non-backtracking matrix of the graph, we provide evidence to suggest that spectral methods fail to provide weak recovery if $\lambda \leq 1. $
The yellowing of thymol in the display of prints

AbstractFramed and glazed prints have been found to yellow rapidly when on exhibition. It was found that the frames all contained the fungicide thymol. Experimental work has shown that the discoloration is caused by photoxidation. The discoloration was present in the paper and in the polymethyl methacrylate glazing. Mass spectroscopy has revealed the presence of a polymer of thymol; there was no evidence for the expected oxidation products.

Analyzing Stemming Approaches for Turkish Multi-Document Summarization

In this study, we analyzed the effects of applying different levels of stemming approaches such as fixed-length word truncation and morphological analysis for multi-document summarization (MDS) on Turkish, which is an agglutinative and morphologically rich language. We constructed a manually annotated MDS data set, and to our best knowledge, reported the first results on Turkish MDS. Our results show that a simple fixed-length word truncation approach performs slightly better than no stemming, whereas applying complex morphological analysis does not improve Turkish MDS.
Novel nonsense mutation in exon 15 of the APC gene in one Jewish family

FAP patients and their families were recruited from the gastroenterology clinic of the Chaim Sheba Medical Center. The APC gene was divided into five segments. The primers sequences containing T7 promotor and conditions of PTT have been previously described by Powell et al. (1993). PCR products were used directly as templates in T n T T7-coupled reticulocyte lysate system (Promega). Incorporation of [35-S] dmethionine (Amersham) was used to detect the translation products after electrophoretic separation on a SDS-polyacrylamide gel with a gradient of 10-20%.
Cardiovascular risk factors in adult patients with multisystem Langerhans-cell histiocytosis: evidence of glucose metabolism abnormalities.

BACKGROUND Langerhans-cell histiocytosis (LCH) is a rare disease with features of chronic inflammation and it may also induce hypopituitarism, conditions associated with an increased risk of cardiovascular diseases. AIM Cardiovascular and metabolic risk profile investigation in multisystem LCH patients with and without anterior pituitary deficiency. DESIGN Prospective, observational study. METHODS Fourteen adult patients with LCH, 7 with and 7 without anterior pituitary deficiency, and 42 controls matched for age, body mass index (BMI) and smoking. Cardiovascular risk factors were estimated in all subjects: glucose and lipid profile, mathematical indices of insulin resistance (IR), blood pressure, structural arterial and functional endothelial properties (intima-media thickness, brachial artery flow-mediated dilatation). Cardiovascular risk factors were estimated in the three groups studied; the effect of disease activity and/or treatment was also determined in patients with LCH. RESULTS Ten patients had diabetes insipidus, and 7 anterior pituitary hormone deficiencies: 8 patients had active disease and 11 had received systemic treatment. No difference was observed between the study groups in vascular parameters, in lipid profile or in blood pressure. However, the insulin resistance index GIR was decreased in patients with LCH without anterior pituitary deficiency compared to controls (P = 0.033). Three patients had impaired glucose tolerance and one diabetes mellitus type 2. These patients were older and had active disease; there was no association with hypopituitarism and/or previous treatment. CONCLUSION Adults patients with LCH have abnormalities of glucose metabolism that tend to occur in patients with active disease, and may be a consequence of the pro-inflammatory state.
Individual Learning in Normal Form Games: Some Laboratory Results☆☆☆

We propose and test a simple belief learning model. We find considerable heterogeneity across individual players; some players are well described by fictitious play (long memory) learning, other players by Cournot (short memory) learning, and some players are in between. Representative agent versions of the model fit significantly less well and sometimes point to incorrect inferences. The model tracks players' behavior well across a variety of payoff matrices and information conditions.Journal of Economic LiteratureClassification Numbers: C72, C73, C92, D83.
The Optimum Control of Inverter Based on Multi-objective Genetic Algorithm

There is many control strategies used in the inverter. However, which is the most efficient control law in the same condition? So in this paper a novel multi-objective optimal SPWM (MOSPWM) control strategy of the inverter based on Genetic Algorithm (GA) is presented, which can find the effective one. In this control strategy a multi-objective function was created, which enables a voltage-source type inverter to produce a near standard sine waveform with a minimum switching loss. Through computer simulation different parameters of GA have been selected in order to reach fitness function optimization, and conducted to evaluate the effectiveness of the new control technology. Comparative analysis proving superiority of the MOSPWM technique over the existing conventional PWM methods is presented.
Oxygen and self-regulation Energy in the Air and Psychological Work : Examining the Relationship Between Oxygen and Self-Regulation

Evidence indicates that self-regulation relies on glucose as a limited energy source, such that self-regulation is impaired when glucose is lower and is improved when glucose is higher. Two studies examined whether levels of oxygen, the other primary energy for the brain, also influences self-regulation. While completing the Stroop task, participants breathed through a paper bag that either did or did not reduce oxygen levels (Study 1) or, while completing a measure of prejudice, participants breathed through a paper bag that either did or did not reduce oxygen levels and that either did or did not have increased oxygen flowing through it (Study 2). Results indicated that these manipulations of oxygen levels did not influence Stroop performance or prejudice. Minor fluctuations in oxygen levels thus do not appear to influence self-regulation.

Braided Block Codes

A new class of binary iteratively decodable codes with good decoding performance is presented. These codes, called braided block codes (BBCs), operate on continuous data streams and are constructed by interconnection of two component block codes. BBCs can be considered as convolutional (or sliding) version of either Elias' product codes or expander codes. In this paper, we define BBCs, describe methods of their construction, analyze code properties, and study asymptotic iterative decoding performance.
Improvising linguistic style: social and affective bases for agent personality

This paper introduces Linguistic Style Improvisation, a theory and set of algorithms for improvisation of spoken utterances by articial agents, with applications to interactive story and dialogue systems. We argue that linguistic style is a key aspect of character, and show how speech act representations common in AI can provide abstract representations from which computer characters can improvise. We show that the mechanisms proposed introduce the possibility of socially oriented agents, meet the requirements that lifelike characters be believable, and satisfy particular criteria for improvisation proposed by Hayes-Roth.
PLM and architectural rehabilitation: a framework to improve the early stages collaboration

Recent evolutions in French law regarding accessibility of public buildings have prompted a rise in the need for methods and tools to rehabilitate such structures in order to make them accessible to disabled users. Architectural rehabilitation is an exceedingly complex design process, in particular because of a legal framework which strongly impacts on the structure of collaboration, and of the need to take into account characteristics of existing buildings. In this paper, we describe a participatory design methodology applied in the rehabilitation of a School of Engineering in France, in order to improve its accessibility, and describe the basic functionalities of a software tool to assist Collaborative Engineering in architectural redesign projects.
