POLYHEDRAL SCHEDULING CACHE

Compiler Design Lab Department of Computer Science Bachelor of Science by Hendrik Leidinger In the more recent past, polyhedral optimizations have become very popular due to the increasing number of parallel architectures [1]. These optimizations improve data locality, expose parallelism and are performed in a mathematical framework, called the polyhedral model. Polly [2] provides an infrastructure for polyhedral optimizations in LLVM [3]. LLVM is a compiler infrastructure offering frontends for many programming languages. Polly detects optimizable code regions, translates them into the polyhedral model, performs mathematical optimizations and translates the result back into the LLVM intermediate representation. Although Polly is a very powerful tool, there remains a major problem: With polyhedral optimizations enabled, the compile-time increases unproportional, making it unpractical for every day use. Recent measurements [4] show, that Polly increases compile-time by about 13.15% even though timeouts are used to limit analysis and optimization time for each benchmark. Some test codes, like the ASC Sequoia Crystalmk benchmark [5], produce an overhead of more than 100%. In this work a caching mechanism for Polly is proposed in order to minimize this overhead in continuous compilations. To achieve this, computed results are stored and reused for similar inputs. The term "similar" is used, since among others, generalization techniques prior to caching are introduced. This allows the results to be reused for equivalent but different inputs.
Evaluating the stage of change model to a cervical cancer screening intervention among Ohio Appalachian women

ABSTRACT Cervical cancer incidence and mortality rates are disproportionally high among women living in Appalachia Ohio. This study used the Transtheoretical Model to examine screening barriers before and after a lay health advisor (LHA) intervention (2005–2009) to increase cervical cancer screening rates. Ohio Appalachian women (n = 90) who were in need of a Pap test, based on risk-appropriate guidelines, were randomized to a 10-month LHA intervention and received two in-person visits, two phone calls, and four mailed postcards targeted to the participant’s stage of change. Findings revealed that 63% had forward stage movement 10 months after the intervention. The most frequently reported screening barriers were time constraints, forgetting to make an appointment, and cost. Women who reported the following barriers—doctor not recommending the test; being unable to afford the test; and being embarrassed, nervous, or afraid of getting a Pap test—were less likely to be in the action stage. Understanding the stages of change related to Pap testing and reported barriers among this underserved population may help inform researchers and clinicians of this population’s readiness for change and how to set realistic intervention goals.
Long‐term evaluation of retinal function in Prph2Rd2/Rd2 mice following AAV‐mediated gene replacement therapy

Prph2Rd2/Rd2 mice have a retinal degeneration due to a null mutation for the Prph2 gene which encodes a photoreceptor‐specific glycoprotein, peripherin2, essential for outer‐segment formation. We have previously shown improvement of photoreceptor function at a single time point following AAV‐mediated gene replacement therapy. Here we quantify the functional rescue over a 15‐week time course and present a detailed analysis of the improvement in retinal function.

Critical analysis of Comparison of the compensation ability of different control strategies based on THD and speed will be done and suggestions will be given for the selection of technique to be used. The simulated results using MATLAB model are presented and they will clearly prove the value of the proposed control method of aircraft shunt APF.
ON AUDIO-TUTORIAL INSTRUCTION : A Meta-Analysis of Comparative Studies

The present article describes a statistical synthesis of results from 48 comparative studies of an innovative method of college teaching, Postlethwalt's Audio-Tutorial or A-T approach. The analysis showed that in general A-T instruction has a significant but small overall effect on student achievement in college courses, and it has no significant effect on student course evaluations or on course completions. Findings were similar for welldesigned and less-well-designed studies included in this analysis, and they were also similar for studies carried out at different types of schools and in different subject areas. Results reported in journals, however, were more favorable to A-T than results found in dissertations and other unpublished reports.
Spatial and seasonal characterization of net primary productivity and climate variables in southeastern China using MODIS data

We developed a sophisticated method to depict the spatial and seasonal characterization of net primary productivity (NPP) and climate variables. The role of climate variability in the seasonal variation of NPP exerts delayed and continuous effects. This study expands on this by mapping the seasonal characterization of NPP and climate variables from space using geographic information system (GIS) technology at the pixel level. Our approach was developed in southeastern China using moderate-resolution imaging spectroradiometer (MODIS) data. The results showed that air temperature, precipitation and sunshine percentage contributed significantly to seasonal variation of NPP. In the northern portion of the study area, a significant positive 32-d lagged correlation was observed between seasonal variation of NPP and climate (P<0.01), and the influences of changing climate on NPP lasted for 48 d or 64 d. In central southeastern China, NPP showed 16-d, 48-d, and 96-d lagged correlation with air temperature, precipitation, and sunshine percentage, respectively (P<0.01); the influences of air temperature and precipitation on NPP lasted for 48 d or 64 d, while sunshine influence on NPP only persisted for 16 d. Due to complex topography and vegetation distribution in the southern part of the study region, the spatial patterns of vegetation-climate relationship became complicated and diversiform, especially for precipitation influences on NPP. In the northern part of the study area, all vegetation NPP had an almost similar response to seasonal variation of air temperature except for broad crops. The impacts of seasonal variation of precipitation and sunshine on broad and cereal crop NPP were slightly different from other vegetation NPP.
Existentialism Is a Humanism

Methodological study of the world-famous French philosopher, playwright, writer J.-P. Sartre (1905-1980) is devoted to the reasoned coverage of the cultural-philosophical achievements of existentialism as a teaching that enables human life and accepts as an axiom the statement that every truth and every action presupposes an environment and subjectivity, which is organized either as a behavior or as a deed. The fundamental principle of this doctrine is formulated in the form of the maxim: “existence precedes essence”, in other words, “it is necessary to proceed from the subject”, which became the indisputable ideologeme of the existential movement for decades. And this means that a person firstly exists, meets, appears in the world and only then is defined and acquires authenticity; therefore, he is primarily a p r o j e c t that is experienced and realized subjectively, thus creating a person out of himself. This is where the humanistic meaning of the worldview doctrine of existentialism emerges: it gives each person ownership of their real being and places full responsibility on them. Moreover, naturalistic determinism is denied in this doctrine, because it supports the opinion that there is no human nature, just as there is no God who would have conceived it. Therefore, the essence of a person is in an irrational plane, associated with complete freedom of actions, feelings of sadness and suffering, spontaneous waves of existential fear, insurmountable absurdity of social everyday life, ultimately with randomness and the experience of abandonment-loneliness. In these dramatic circumstances of a world full of vanity and senselessness, a person is doomed to be free, with the potential of his own consciousness to create personal values and determine the meaning of life, to exist for the constant fulfillment of himself, to establish himself in relations with others through the totality of his actions, expanding the inner horizons of both his own authenticity and specific intersubjectivity. He is always face to face with a changing situation, therefore the choice is always a choice in a clearly defined situational context of being. Therefore, existentialism is a philosophical doctrine of action, a person’s presence in the world, and therefore an optimistic, liberating, humanistic teaching.
An international survey of classification and treatment choices for group D retinoblastoma.

AIM To determine which IIRC scheme was used by retinoblastoma centers worldwide and the percentage of D eyes treated primarily with enucleation versus globe salvaging therapies as well as to correlate trends in treatment choice to IIRC version used and geographic region. METHODS An anonymized electronic survey was offered to 115 physicians at 39 retinoblastoma centers worldwide asking about IIRC classification schemes and treatment patterns used between 2008 and 2012. Participants were asked to record which version of the IIRC was used for classification, how many group D eyes were diagnosed, and how many eyes were treated with enucleation versus globe salvaging therapies. Averages of eyes per treatment modality were calculated and stratified by both IIRC version and geographic region. Statistical significance was determined by Chi-square, ANOVA and Kruskal-Wallis tests using Prism. RESULTS The survey was completed by 29% of physicians invited to participate. Totally 1807 D eyes were diagnosed. Regarding IIRC system, 27% of centers used the Children's Hospital of Los Angeles (CHLA) version, 33% used the Children's Oncology Group (COG) version, 23% used the Philadelphia version, and 17% were unsure. The rate for primary enucleation varied between 0 and 100% and the mean was 29%. By IIRC version, primary enucleation rates were: Philadelphia, 8%; COG, 34%; and CHLA, 37%. By geographic region, primary enucleation rates were: Latin America, 57%; Asia, 40%; Europe, 36%; Africa, 10%, US, 8%; and Middle East, 8%. However, systemic chemoreduction was used more often than enucleation in all regions except Latin America with a mean of 57% per center (P<0.0001). CONCLUSION Worldwide there is no consensus on which IIRC version is used, systemic chemoreduction was the most frequently used initial treatment during the study period followed by enucleation and primary treatment modality, especially enucleation, varied greatly with regards to IIRC version used and geographic region.
An Approach to Discovery and Re-ranking of Educational content from the World Wide Web using Latent Dirichlet Allocation

With tremendous increase in the amount of digital data available educators are forced to author content for learning and teaching for use in their classes. With that there has emerged a need to facilitate automatic discovery of learning resources from the World Wide Web. In this work, we present a novel approach for discovering content from the web for e-learning. We argue that for an e-learning scenario, retrieval of the redundant content from the web is a serious problem to be addressed as it does not satisfy the requirements of a typical learner. Furthermore, the content retrieved should cover all topics as in his syllabus. Sense-disambiguation should be performed during information retrieval from the web so that it corresponds to the learner‟s actual domain of interest. This work presents a domain ontology based re-querying approach for query expansion to discover content from open corpus sources. We use the Latent Dirichlet Allocation Model for unsupervised classification of document segments to aid students and educators. Having identified the topics at the granularity of document segments in an unsupervised fashion, we state that internal topic transitions in a resource retrieved from the web can be exploited for providing relevant and personalized content. In addition to this, we propose a re-ranking scheme for ordering results from search engines to maximize topic coverage and minimize redundancy among retrieved results. We also evaluate the effectiveness of our proposed method for information retrieval and show that our work results in greater coverage of topics from the web without redundancy.

Factors Influencing Slovak Consumer´s Actual Buying Behavior towards Fresh Vegetable

The main objective of the submitted paper was to identify factors influencing the behaviour of Slovak consumers on the market with fresh vegetable. Primary data were obtained through a questionnaire survey, which was carried out on a randomly selected sample of 390 respondents in Slovakia. The questionnaire survey was conducted online in November and December 2017. The obtained data were analysed by using Excel program as well as the statistical programming language R. For a deeper analysis of the collected data, we formulated several scientific assumptions. We verified their accuracy with the Chi-Square Test of Independence, Cramer ́s V Coefficient, Fisher ́s Test and Kruskal-Wallis Test. Based on our research we the conclusion is that consumers while buying fresh vegetable are most influenced by the freshness of vegetable, taste, maturity, quality as well as the general appearance of vegetable. Moreover, we found out that there existsdependence between attributes, which are the most important to respond to the purchase of vegetable (price, colour, taste, shape, size, smell, maturity, general appearance) and what is most attracted to the vegetable counter. Based on our research, we also proved dependence between the purchase of vegetable and respondent ́s place of residence as well as dependence between consumers ́ attitude towards organic products and preferences of origin. Finally, following the significance of selected factors, we examined the dependence of their perceptions on the socio-demographic characteristics of the respondents.

The quality of citations in major international obstetrics and gynecology journals.

OBJECTIVE Our goal was to determine the error rate in references in articles published in three major international journals in obstetrics and gynecology. STUDY DESIGN All issues (excluding supplements) for the year 1995 of the American Journal of Obstetrics and Gynecology, the Australian and New Zealand Journal of Obstetrics and Gynaecology, and the British Journal of Obstetrics and Gynaecology were examined. References were numbered sequentially, and 50 randomly selected references from each journal were checked against the original for accuracy. RESULTS Errors were found in the majority of references. The lowest error rate was 55.6% from the Australian and New Zealand Journal of Obstetrics and Gynaecology, and the highest was 66.7% from the British Journal of Obstetrics and Gynaecology. The difference between journals was not statistically significant. The most frequent types of error were in the title of the article or in the authors' names. CONCLUSIONS Error rates in major international journals in obstetrics and gynecology are high, and care must be taken by authors and journal staff to improve the quality of published articles.
Approche expérimentale et numérique de l'usinage à sec de l'alliage aéronautique TA6V

Pour optimiser l’usinage, il faut d’abord comprendre les mecanismes d’endommagement des outils de coupe. Pour cela, il est necessaire de connaitre l’evolution des parametres de contact outil/copeau avec les conditions d’usinage. Dans ce sens, des essais de coupe orthogonale en rabotage et tournage ont ete mis en place. Leur instrumentation nous permet d’acceder a la morphologie des copeaux, au frottement a l’interface outil/copeau, a la longueur de contact outil/copeau. Le mecanisme de formation des festons de copeau en TA6V et la mesure de l’angle de cisaillement sont egalement accessibles par l’utilisation d’une camera video rapide CCD. Les champs de temperature et de contraintes developpes au voisinage de l’interface outil/copeau influent de facon importante sur la duree de vie des outils. Ils sont difficilement accessibles par l’experimentation, mais peuvent etre determines a l’aide de simulations numeriques du processus de coupe. Leur justesse est conditionnee par la capacite de la modelisation a predire des efforts de coupe et une morphologie du copeau en accord avec l’experimentation. La principale difficulte des approches numeriques concerne la prediction de la morphologie particuliere du copeau de TA6V. Le nouveau modele de comportement developpe dans ce projet tient compte de transformations microscopiques comme la restauration et/ou la recristallisation dynamique. Il a ete introduit dans les simulations numeriques de l’usinage et a conduit a l’obtention d’une bonne correlation entre les predictions et les resultats experimentaux pour une large gamme de vitesses de coupe.
Social Media As A Market Communication Tool In Healthcare

Healthcare performance is strongly dependent on the health system and its efficiency. This paper discusses social media as a tool for higher effectiveness of communication among the key healthcare stakeholders ? patients and physicians ? in the period of digital society. Based on the findings of previous research and case study analysis on Slovenian healthcare context, the paper provides a framework of key motives, advantages, risks, personal attributes and contextual factors that influence the use of health-related social media. Together with the proposed key supportive mechanisms the framework is developed into a holistic conceptual model of market communication in healthcare via social media.
Modélisation Markovienne – Modèles de régression de copules et valeurs extrêmes – Application aux systèmes d’aide à la conduite

Cette these s'organise en deux grandes parties. La premiere partie porte sur le systeme d'aide a la conduite ACC. Nous etudions les strategies de conduite et confirmons une hypothese de F. Saad dans le premier chapitre. Le second chapitre aborde les automates cellulaires. Le troisieme chapitre propose la validation d'une hypothese dans le domaine de la psychologie de la conduite par l'utilisation de la modelisation markovienne. Le dernier chapitre porte sur la modelisation markovienne avec exogenes. Nous comparons avec une modelisation classique. Un cadre theorique est presente. L'etude d'outils pour l'evaluation d'un systeme d'aide a la conduite par le biais d'une comparaison avec/sans et cela sur des donnees reelles non controlees est central. Ceci nous a amene a considerer la notion de scene pouvant se definir comme la modification de la dependance entre plusieurs indicateurs. L’objet central dans la dependance est la copule, cœur de la seconde partie. Le premier chapitre est un etat de l'art, evoque les mesures de dependance et la fonction de linkage. Le second chapitre aborde une mesure de dependance multivariee. Nous demontrons une formule de decomposition de l'information mutuelle. Le troisieme expose une extension du modele de cox au cas bivarie s'appuyant sur les copules de valeurs extremes. Des resultats d'approximation et de convergence sont prouves. Pour conclure, une application est presentee sur les donnees du systeme lavia (limiteur de vitesse s'adaptant a la vitesse autorisee). Le quatrieme chapitre porte l'estimation de la fonction de dependance d'une copule bivariee. On demontre la convergence uniforme ainsi que la loi asymptotique de notre estimateur
Méthode asymptotique numérique pour l'étude multi échelle des instabilités dans les matériaux hétérogènes

La modelisation multi-echelle des materiaux heterogenes est un challenge en mecanique numerique. Dans le contexte non lineaire, les proprietes effectives des materiaux heterogenes ne peuvent pas etre obtenues par les techniques utilisees pour les milieux lineaires car le principe de superposition n'est plus valable. Ainsi, dans le contexte des elements finis, une alternative au maillage de l'ensemble de la structure avec la prise en compte de toutes les heterogeneites, est l'utilisation de la methode d'elements finis multi-echelles (EF2). Les techniques de ce type offrent de nombreux avantages, tels que la prise en compte : des grandes deformations au niveau micro et macro sont souvent resolus par les procedures classiques de Newton-Raphson, qui sont generalement adaptees a la resolution des problemes non lineaires mais qui presentent des difficultes en presence d'instabilites. Dans cette these, la combinaison de la methode des elements finis multi-echelles (EF2) et la methode asymptotique numerique (MAN), surnommee MAN multi-echelle, permet de mettre en ? uvre une technique numerique efficace pour traiter les problemes d'instabilites dans le cadre des materiaux heterogenes. Ces instabilites peuvent survenir a la fois au niveau micro et au niveau macro. Differentes classes de comportement des materiaux ont ete implantees dans notre procedure. Pour ameliorer le conditionnement du probleme multi-echelle a resoudre, une technique d'homogeneisation du second ordre a ete egalement adaptee dans le cadre de la technique MAN multi-echelle. Par ailleurs, afin de reduire le temps de calcul, quelques techniques ont ete proposees dans ce travail
Voluntary Disclosures by Activist Shareholders ∗

Using hand-collected data, we find that activist shareholders often publicly disclose open letters that demand various changes in corporate operating decisions at their target firms. These letters are associated with significant stock price movements, decreased bid-ask spreads, and key activism outcomes such as directorship wins, corporate strategy shifts, and proxy advisor recommendations. Managers commonly respond to activists’ open letters with their own voluntary disclosures. We conclude that activists use voluntary disclosure to mitigate investor information asymmetry and that managers’ voluntary disclosures can be induced by activists.
