Performance Analysis of OpenFlow Hardware

OpenFlow is a protocol that defines an open control channel towards the data plane of multiple switches from different vendors. This allows for a scalable implementation when running a large network. There has been growing interest in OpenFlow within the networking industry, with the promise of new versions and features added by the Open Networking Foundation (ONF). However, there is a lack of research in the performance of the switches that support it and if their performance will actually allow for the promised scalability. This report aims to fill this void by benchmarking three different hardware implementations provided by SARA with respect to their performance and OpenFlow features. Tested platforms include a NetFPGA card, Pica8 OpenFlow on a Pronto switch and the Open vSwitch implementation on the same switch platform. Tests include looking into the lookup procedure by the switches, Quality of Service features and impact of failover flows. In the end it appears that although the most basic forwarding features are available in the implementations tested, scalability is a characteristic, which cannot yet be added to the OpenFlow feature set. While the performance scalability could be improved by optimizing the hardware design, one of the more significant bottlenecks seems to be the interoperability between OpenFlow firmware of switches, their hardware and the software used to control them.
Simulation Study for Performance Comparison of Routing Protocols in Mobile Adhoc Network

--- Due to insufficient frequency band and tremendous growth of the mobile users, complex computation is needed for the use of resources. Long distance communication began with the introduction of telegraphs and simple coded pulses, which were used to transmit short messages. Since then numerous advances have rendered reliable transfer of information both easier and quicker. Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes is implemented without the use of wires. Wireless network can be broadly categorized in infrastructure network and infrastructure less network. Infrastructure network is one in which we have a base station to serve the mobile users and in the infrastructure less network is one in which no infrastructure is available to serve the mobile users this kind of networks are also known as mobile Adhoc networks. In this paper we have simulated the result for different scenarios with protocols like AODV and DSR; we simulated the result for throughput, delay and receiving traffic in the given scenario.
A homotopy exact sequence for overconvergent isocrystals

Abstract In this article we prove exactness of the homotopy sequence of overconvergent fundamental groups for a smooth and projective morphism in characteristic p. We do so by first proving a corresponding result for rigid analytic varieties in characteristic $0$, following dos Santos [dS15] in the algebraic case. In characteristic p, we then proceed by a series of reductions to the case of a liftable family of curves, where we can apply the rigid analytic result. We then use this to deduce a Lefschetz hyperplane theorem for convergent fundamental groups, as well as a comparison theorem with the étale fundamental group.
LIVER X RECEPTORS (LXRS): TRANSCRIPTIONAL REGULATORS OF MACROPHAGE CHOLESTEROL METABOLISM

Liver X receptors (LXRα and LXRβ) are oxysterol-activated nuclear receptors. These sterolresponsive transcription factors regulate the expression of genes involved in intestinal cholesterol absorption and conversion of cholesterol to bile acids [1]. Since the macrophage plays an important role in host defense and immuno-inflammatory responses, particular interest has been paid to the role of LXRs in the control of macrophage gene expression and function. Altered macrophage functions contribute to the pathogenesis of many infectious, immunological and inflammatory disease processes, including atherosclerosis. Research reported over the last few years revealed important roles for LXRs in macrophage inflammation and cholesterol homeostasis with consequences in atherosclerosis development.
New Horizons in Entrepreneurship: From Teacher-Led to Student-Centered Learning.

Purpose – The purpose of this paper is to contribute to the discussion about the complexity and heterogeneity of entrepreneurship education. In order to achieve this objective, this paper combines educational psychology with perspectives from entrepreneurship education research to make explicit educators tacit assumptions in order to understand how these assumptions guide teaching. Design/methodology/approach – Using ethnographic analysis, the paper reports data from the continuous development and implementation of a single course over a period of ten years bringing in the educator’s and the students perspectives on their achievements and course content. Findings – The authors find that it is sometimes advantageous to invoke and combine different learning theories and approaches in order to promote entrepreneurial awareness and mindset. It is also necessary to move away from entrepreneurship education as being teacher led to being more student-centred and focused on experiential and existential lifelong l.
The Determinants of e-WOM for Infomediaries in Social Commerce

The explosive growth of social commerce engenders a new business model, that is, infomediary. In a social commerce environment, infomediary works as a personal agent who provides information about various web merchants to help consumers select appropriate merchants for their needs. The purpose of this study is to identify the factors influencing consumer attitudes towards infomediaries in social commerce and examine the relationship between intention to provide word of mouth and consumer attitudes. In total, 170 responses were collected from social commerce infomediary users. The results show that competence and integrity significantly influence user attitudes as trust dimensions. Infomediary reputation and two functional factors (information variety and navigation functionality) turn out to be significant antecedents for user attitudes toward infomediary in social commerce. User attitudes in turn significantly influence the intention to provide word of mouth. Future research and practical implications are also discussed.
Cardiac Remodeling and Recovery: Lessons from Mechanical Ventricular Assist Devices

Cardiac injury, regardless of etiology, typically leads to an increase in wall stress, decreased compliance, reduced systolic function, and progressive chamber dilation. This process is termed “remodeling” and is associated with a worse prognosis in patients with heart failure. Several drugs have been shown to have an effect on inducing reverse remodeling or reducing ventricular dilatation, including angiotensin-converting enzyme (ACE)-inhibitors, angiotensin receptor blockers (ARBs), beta-blockers and, most recently, aldosterone inhibitors. Two mechanical interventions have also been associated with reverse remodeling: biventricular pacing (so-called cardiac resynchronization therapy) and mechanical ventricular assist devices (VADs). Left VADs (LVADs) induce the most complete reverse remodeling by far, returning the ventricle to nearly normal chamber size within days to weeks. The use of VADs has evolved over the last 25 years and, currently, a significant number and type of devices with improved sophistication, durability, and reliability are available. The device most commonly used today is a pulsatile pump that is placed internally, either preor intraperitoneally, such as the HeartMate (Figure 1) or Novacor devices. These devices are able to fully support the circulation by draining nearly all the blood normally entering the left ventricle and pumping it back into the circulation by pusher plate compression of a blood reservoir in the pump. This support or output is pulsatile and synchronous with the intrinsic cardiac rate and rhythm. More recently, VAD technology has evolved to include axial or continuous flow pumps such as the Micromed-DeBakey (Figure 2) or Jarvic pumps. These pumps are able to almost totally decompress the cardiac ventricle, but use axial (continuous) rather than pulsatile flow. There is significant evidence to suggest that the total reduction in wall stress that is achieved via mechanical unloading with VADs is able to induce significant structural, cellular, molecular, and functional reverse remodeling of the myocardium. This issue of Cardiology Rounds reviews the data regarding reverse remodeling and the potential for meaningful recovery of ventricular function associated with these devices.
The Secondary Vocational Agriculture Curriculum From 1890 to 1980

In the novel Moon Val ley, wr i t ten by John F. Case in 1932, the tr ials and tr ibulat ions of a young col lege graduate named Tom Woodson returning to his home community to teach vocat ional agriculture are chronicled. One of the f irst tasks faced by young Woodson was to organize the curr iculum. C a s e (p. 49) w r i t e s , “Contrary to the frequent pract ice of taking up animal husbandry work in the beginning of the vocat ional agr icul ture instruct ion, Tom Woodson had decided upon crop projects.

RENÉ THOM’S WORK ON GEOMETRIC HOMOLOGY AND BORDISM

By the early 1950’s algebraic topology had reached great heights with Serre’s thesis and the calculations in the seminar of Henri Cartan of the cohomology of spaces with one nonzero homotopy group in terms of Steenrod operations. There was also the appearance of the new characteristic classes of vector bundles, Pontryagin classes (Z coefficients) and Chern-Weil classes (coefficients in R) joining those of Stiefel Whitney (Z mod 2 coefficients). René Thom absorbed all this structure, made vigorous use of it, and added a geometric perspective that combined to revolutionize topology, manifold theory, and algebraic geometry. For the unexpected and fertile results in bordism (closed manifolds mod boundaries of manifolds) of the 1954 paper [1], Thom received the Fields Medal at Edinburgh in 1958. Many more applications of Thom’s ideas came even later.
Personality and career success

The relationship between personality and career success has provoked a great deal of speculation. It has often been asserted that achievement (especially in capitalist economies) can be explained largely by factors such as individual initiative, effort, and merit. This is the classic “Horatio Alger” story of how one gets ahead in life—through grit, determination, and effort. In this sense, personality is probably a significant determinant of how people will do in their careers. At the same time, luck and institutional factors—such as privilege or inheritance—may influence career success in a way that would attenuate the relationship with personality significantly. Tharenou’s (1997) review of the empirical research identified several categories of explanations for career success and found that research has generally favored institutional explanations over individual explanations. Whereas the most commonly investigated influences were demographic (age, sex, marital status, number of children) and human capital (training, work experience, education), researchers have increasingly investigated the possible role of personality in explaining career success. Below, we discuss the dispositional factors that have been related to career success in past research. Before doing so, however, it is important to discuss what we mean by career success and to discuss an organizing framework for our discussion of trait influences on career success (in particular, the five-factor model, FFM).
ANOMALOUS LOW STATES AND LONG-TERM VARIABILITY IN THE BLACK HOLE BINARY LMC X-3

Rossi X-ray Timing Explorer observations of the black hole binary LMC X-3 reveal an extended very low X-ray state lasting from 2003 December 13 until 2004 March 18, unprecedented both in terms of its low luminosity (>15 times fainter than ever before seen in this source) and long duration (∼3 times longer than a typical low/hard state excursion). During this event little to no source variability is observed on timescales of ∼hours–weeks, and the X-ray spectrum implies an upper limit of 1.2 × 1035 erg s−1. Five years later another extended low state occurs, lasting from 2008 December 11 until 2009 June 17. This event lasts nearly twice as long as the first, and while significant variability is observed, the source remains reliably in the low/hard spectral state for the ∼188 day duration. These episodes share some characteristics with the “anomalous low states” in the neutron star binary Her X-1. The average period and amplitude of the variability of LMC X-3 have different values between these episodes. We characterize the long-term variability of LMC X-3 before and after the two events using conventional and nonlinear time series analysis methods, and show that, as is the case in Her X-1, the characteristic amplitude of the variability is related to its characteristic timescale. Furthermore, the relation is in the same direction in both systems. This suggests that a similar mechanism gives rise to the long-term variability, which in the case of Her X-1 is reliably modeled with a tilted, warped precessing accretion disk.
What should be done to decrease the incidence of human salmonellosis in Canada

The thesis i s concerned with what should be done to decrease the incidence of human salmonellosis i n Canada. The present high incidence of Salmonella contaminated poultry i s reviewed and evidence i s given that links Salmonella contaminated poultry carcasses at the r e t a i l level to human salmonellosis. The question i s raised as to whether control or eradication should be the goal i n Canada, and present regulations involving various levels of Governments are examined. The incidence of Salmonella contaminated poultry i n some other countries i s reviewed, together with some of the Salmonella control programmes that have been instituted by these countries. Finally, certain recommendations are made, as to what could be done i n Canada to decrease the incidence of human salmonellosis. These recommendations stress the need for further research to develop ways of decreasing the incidence of Salmonella contaminated poultry at the r e t a i l l e v e l . The colonization of the gut of day-old chickens with the intestinal f l o r a of adult chickens i s a method that shows promise. The use of radiation and chlorination of the poultry carcasses would also help to reduce the incidence of carcass contamination. If Canada i s determined to reduce human salmonellosis, then steps must be taken to coordinate the many different branches of both
Quantum computing and the entanglement frontier

Quantum information science explores the frontier of highly complex quantum states, the "entanglement frontier. " This study is motivated by the observation (widely believed but unproven) that classical systems cannot simulate highly entangled quantum systems efficiently, and we hope to hasten the day when well controlled quantum systems can perform tasks surpassing what can be done in the classical world. One way to achieve such "quantum supremacy" would be to run an algorithm on a quantum computer which solves a problem with a super-polynomial speedup relative to classical computers, but there may be other ways that can be achieved sooner, such as simulating exotic quantum states of strongly correlated matter. To operate a large scale quantum computer reliably we will need to overcome the debilitating effects of decoherence, which might be done using "standard" quantum hardware protected by quantum error-correcting codes, or by exploiting the nonabelian quantum statistics of anyons realized in solid state systems, or by combining both methods. Only by challenging the entanglement frontier will we learn whether Nature provides extravagant resources far beyond what the classical world would allow.
ANTAGONISTES DE L'ENDOTHELINE

L’endothéline est un peptide de 21 acides aminés, qui est considéré comme étant le vasoconstricteur endogène le plus puissant connu à ce jour. La caractérisation des effets biologiques de l’endothéline (proches de ceux de l’angiotensine II), en particulier de ses effets hypertenseurs et stimulants de l’hypertrophie, mais aussi l’observation que de nombreuses pathologies sont associées à une activation du système de l’endothéline, suggèrent que l’inhibition de ce système peptidique pourrait exercer des effets bénéfiques dans différentes pathologies, en particulier dans le domaine cardiovasculaire.
A New Stemmer to Improve Information Retrieval

A stemming is a technique used to reduce words to their root form, by removing derivational and inflectional affixes. The stemming is widely used in information retrieval tasks. Many researchers demonstrate that stemming improves the performance of information retrieval systems. Porter stemmer is the most common algorithm for English stemming. However, this stemming algorithm has several drawbacks, since its simple rules cannot fully describe English morphology. Errors made by this stemmer may affect the information retrieval performance. The present paper proposes an improved version of the original Porter stemming algorithm for the English language. The proposed stemmer is evaluated using the error counting method. With this method, the performance of a stemmer is computed by calculating the number of understemming and overstemming errors. The obtained results show an improvement in stemming accuracy, compared with the original stemmer, but also compared to other stemmers such as Paice and Lovins stemmers. We prove, in addition, that the new version of porter stemmer affects the information retrieval performance.
ANEVRYSME DU SEPTUM INTERAURICULAIRE

anévrysme du septum interauriculaire (ASIA) correspond à une protrusion du septum dans l’une ou l’autre des oreillettes. Sa fréquence dans la population générale est estimée à 1 % d’après les séries autopsiques (1) ou les études échocardiographiques par voie œsophagienne (2, 3). Actuellement, son diagnostic est facilement porté par l’échographie cardiaque transthoracique (ETT), ou mieux par l’échographie par voie œsophagienne (ETO), dont la sensibilité est supérieure (4). L’ASIA est défini échographiquement par une excursion d’au moins 15 mm par rapport au plan du septum interauriculaire, avec une base d’implantation supérieure ou égale à 15 mm. Une classification a été réalisée par l’équipe de la Mayo Clinic, qui différencie trois sous-types d’ASIA en fonction de leurs mouvements au cours des cycles respiratoire ou cardiaque (figures 1, 2 et 3) (5).

AData ow-basedMassivelyParallelProgrammingLanguage "V" and Its Implementation on A Stock Parallel Machine

We propose a data BLOCKINow-based massively parallel programming language, called \V," which would minimize the diculties in writing massively parallel programs. The language V has both merits of functional programming and object-based programming. Our starting point is a data BLOCKINow-based functional programming language, called \Valid," which we have developed so far, because functional programming paradigm is able to abstract away the timing problem, that is the problem of execution sequence and synchronization control, in writing massively parallel programs. The language V provides an object-based (or multi-agent) abstraction, called \agent," to write parallel entities which have their own states in them and communicate with each other. In addition, we can connect agents explicitly and abstract an ensemble of agents on a predened topology description, called \eld," in order to write a massively parallel program which naturally re BLOCKINects the structure of the problem. As the language V has its basis on a data BLOCKINow-based functional programming language originally designed for data BLOCKINow architecture, it is easy to extract parallelism of various level. In our implementation, the compiler extracts ne-grain parallel threads in the rst stage, and then schedules the ne grain parallel threads and constructs coarser grain threads to exploit as much eective paral-lelism as target machines can provide. In this paper, implementation issues for a distributed-memory parallel machine, Fujitsu AP1000, are discussed. We also show and discuss a preliminary evaluation of our compiler and runtime system developed for AP1000.
Developmental Implications of Sleep

This review attests to the fact that the connections between sleep and developmental issues including cognitive, developmental and emotional domains in early-to-late childhood are more complex than as reflected in early writings. In the face of broad and multifaceted nature of the fact, this work is relatively concise in coverage. Research has indicated significant changes from birth to early-childhood in sleep characteristics in terms of sleep patterns and sleep duration. Children show significant variation in their sleep characteristics as a function of environmental conditions and internal factors such emotional states or physical conditions. The qualitative and quantitative changes in sleep patterns during the early-childhood appear to be occurring in consonant with developmental features and implicated in cognitive, behavioral and emotional development of child. Even though the number of studies in children and adolescents is scarce, the associations between trouble sleep and emotional dysregulation have consistently reported that persist from childhood into early- to mid-adolescence. This review addresses three topics with regards to the importance of sleep in the childhood: i) characteristics of sleep and alteration in these characteristics from infancy to early childhood including development of more complex structures resemble adult sleep and consolidation of sleep wake cycle accompanied by quantitative changes in daytime naps and nighttime sleep; ii) associations between sleep and developmental domains, particularly cognitive and emotional development; and iii) importance of healthy sleep habits and sleep hygiene. The empirical evidence and theoretical considerations within the literature are refined and discussed herein.
Affording Cultural and Social Presence in E-Marketing

This chapter discusses the relationships among several concepts important to Web design, marketing communications and consumer behavior. Originally from psychology literature, the concept of affordances, the result of interaction between a human and an object, has emerged in product design literature. This chapter extends the concept to design of mediated environments, stressing detailed social and cultural contextual elements and potential behaviors. Vividness and interactivity in mediated environments are requisite qualities for inducing a sense of presence, consumers’ perception on some level that a mediated environment is non-mediated. Well-designed mediated environments afford consumers online opportunities to modify relationships with their environments.
