Full Text Available The state of water ecosystem is constantly affected by natural processes. Moving substances and energy in this system form a new dynamic balance which changes the parameters of the system itself. In the system, substances rotate from one link to another, while energy moves to one or the other direction, therefore thermodynamic parameters: mass, energy, entropy, enthalpy and their transfers of a metabolism process are to be estimated.
Oxygen concentration in the system influences the processes of organic substances production and destruction i.e. their intensity, thermodynamic stability, spontaneous purification and ecosystem state. By oxidizing nutrients a cell gathers energy for biosynthesis reactions, movement, and substances transfer. The energy released during oxidation-reduction reactions is consumed to maintain the building of a cell. On the basis of the variation of oxygen concentration, organic chemical impurities in water ecosystem are qualitatively and quantitatively analyzed. Concentration of nutrients in the system is indirectly evaluated by BOD and COD parameters which are susceptible to time and may be unreliable.
For this reason, to monitor the parameters, to prevent the discharge of badly treated wastewater, to control the technological process of wastewater treatment equipment, the efficient, fast and low-cost methods are to be developed.
The existing methods of determining the qualitative parameters of water ecosystems have been studied, compared among each other with the experimental results obtained by the comparative analysis method. When comparative parameters are determined by technological, legal, consumer and scientific approach and their evaluation scale is set up, the methods are evaluated as to the rate of the system state estimation. After the analysis of the methods of water system condition evaluation, all methods based on estimation of chemical, physical and biological parameters have been found to

provide information on the basic principles of meta-analysis, be guidance on the application process and promote the use of the method in the nursing field. Özet Son yıllarda sağlık alanında bilimsel gelişmelerin var olması ve iyi bakım uygulamalarına olan ilginin artması gibi nedenlerle kanıta dayalı uygulamaya olan ilgi artmıştır. Kanıta dayalı uygulamalar bakımın kalitesini iyileştirir iken hemşireliğin profesyonelleşmesine de katkı sağlayacaktır. Ancak, bilimselleşme yolunda yapılmış çalışma sonuçlarına bakıldığında; sonuçlar arasında çelişkilerin olduğu, her bir çalışmanın farklı kalitelerde olduğu görülmektedir. Çalışmalar arasındaki çelişkilerin eleştirel değerlendirilmesi ve farklılıkların nedenlerinin istatistiksel olarak analiz edilmesi için meta-analiz yöntemi geliştirilmiştir. Aynı konu ile ilgili birbirinden bağımsız farklı yer ve zamanda yapılan çalışma sonuçlarının istatistiksel analizine meta-analiz denilmektedir. Meta-analiz; bir etkinin varlığını ve büyüklüğünü ortaya koyan, çalışmalar arasında var olan tutarsızlıkları ve nedenlerini inceleyen, araştırma sonuçlarını daha önce incelenmemiş olan yeni parametreler ile inceleyebilen, böylece olası yeni ilişkilileri ortaya çıkartabilen ve daha sonraki yapılacak çalışmalara yeni yaklaşımlar getirebilen bir analiz yöntemidir. Meta-analiz uygulama süreci ise zaman alıcı ve sabır isteyen bir süreçtir. Meta-analiz uygulama basamakları; araştırma konusunun ve sorularının belirlenmesi, literatür araştırmasının yapılması, ölçütlerin belirlenmesi, bulunan makalelerin sınıflanması ve elenmesi, verilerin kodlanması, çalışmaların kalitesinin değerlendirilmesi, istatistiksel analizlerin yapılması ve çalışma sonuçlarının raporlanmasını içermektedir.

Full Text Available Victims of prison-overcrowding in Italy are part of a structural and systemic problem which is still struggling to find plausible solutions. When natives and foreigners are separately considered, the overcrowding phenomenon assumes a perspective that goes beyond the mere Italian attribute and, therefore, better focalises on the ones who, having the status of foreigner, are somehow in a weaker position in comparison with the native ones. As a matter of fact, the combination foreign prisoner-overcrowding has allowed to address the prison issue in accordance with a more specific approach that compares the Italian native component and the foreign one. This highlights that the overcrowding phenomenon in Italy is not an aspect suffered mainly by foreign prisoners, but it is equally endured by most of the native ones. Additionally, this analysis takes into account, on the one hand, the most outstanding foreign nationalities housed in Italian prisons and, on the other hand, the Regions having the highest rates of overcrowding, foreign inmates, and prison capacities. The outcomes reveal that Moroccans, Romanians, Tunisians and Albanians are the ones at increased risk of prison overcrowding since, in fact, they represent 60.0% of the total foreign presence in the Italian jails. However, there is a sort of “equal overcrowding distress” that comes out of this context: actually, the four major foreign presences are housed at the same percentage by the six selected Regions (the most overcrowded by foreigners, circumstance that generates a kind of homogeneity of the unlivable conditions in prisons.

Full Text Available This article analyses the statistical procedures used in the proceedings of the one of the psychology conferences regularly organized in Romania. 111 papers in six branches of applied psychology were scrutinized. The analysis was structured on descriptive statistics (numerical and graphical, and inferential statistics (parametric and nonparametric. Was also pursued the extent to which papers complied with APA recommendations on the reporting of confidence limits and size effect. Results: 64.9% of the papers reported statistical results. The sections with more statistical based papers are military psychology (85.7% and industrial-organizational psychology (84%. On the other hand, only 52.4% papers on educational psychology reported statistics procedures. The average of the reported samples was 190 subjects (minimum 10, maximum 1519. A percentage of 26.4% of works includes at least one statistical descriptive indicator, while 31.9% of works containing statistics, have no descriptive indicators. The graphics used are mostly bar and pie. Regarding inferential statistics, 47.2% of work contains at least one statistical test, and 36.1% have none statistical test. The most frequent utilized tests are Pearson r and t tests. It was recorded no single case of reporting effect sizes and confidence limits. Conclusions: The results allow us to appreciate that the papers presented at scientific events, most of them by young psychologists, contain a relative insufficiently matured statistical analysis, and often insufficient connected to the problem studied. We must appreciate, however, as positive the interest in empirical research and statistical analysis of results.

Full Text Available Lucrarea pe care o propunem vizează istoria traducerilor românești ale poemelor homerice, din perspectiva evoluției limbii române literare. Pornim de la premisa că orice asemenea traducere reprezintă o probă de virtuozitate nu numai pentru traducătorul în cauză, ci și pentru limba și cultura modernă respectivă, așa încît este interesant de studiat modul în care dezvoltarea exegezei homerice și a teoriilor traductologice se manifestă în paralel cu etapele evoluției limbilor moderne. Grila de analiză va include, așadar, principii, metode și instrumente de lucru ale domeniilor amintite aici (istoria limbii, traductologie, dar și elemente împrumutate din gramatica constrastiv-tipologică, din filologie, în sensul restrîns al conceptului, din teoria mentalităților, istoria culturală ș.a. Demersul nostru evidențiază faptul că evoluția istorică a actului traducerii este marcată, în mod firesc, de personalitatea traducătorului (opțiuni teoretice, ideologice, pe lîngă competențe lingvistice, har poetic etc., dar și de contextul cultural al epocii și al spațiului respectiv. Pentru cultura română, cel puțin, putem constata că, în ansamblu, versiunea cea mai recentă este și cea mai reușită.

Full Text Available It is proved fact through scientific studies that the pay has adirect influence on productivity and job satisfaction at the same time.The pay gained as a result of the performance is considered asinterrelated both with the increase in the productivity and improvementin the quality of the service. It is vital for the organizational justice thatpeople who have similar statues and who are performing similar tasksshould receive balanced payments. However, the diversity of the publicservices, redundancy of people and formal institutions providing publicservices make it hard to guarantee a fair payment policy. It is observedas a result of comparative studies that academicians are one of theseoccupational groups who are profoundly affected by the injustice in thepayments. In order to remove the injustice in the formal officers’incomes and attain the defined goals for the 100th anniversary of thefoundation of the Republic within the scope of 2023 vision, talentedindividuals must be encouraged to become academicians. When acomparison made between public officials on the national basis, it isrealized that academic staff working at public universities are not ableto benefit from yearly increases as much as the other public officers andit leads for the fresh academicians to move away from academicprofession. As for the international point of view, it is stated that thepayments that the Turkish academicians get are below the average incomparison to their colleagues. In this study, current situation ofmonthly income of the academicians working at public universities inTurkey and it’s the yearly increases in the payment in time arementioned, national comparisons are made between differentprofessions together with international comparisons betweenacademicians from different countries. Ücretin verimlilik ve iş doyumuna etkisi yapılan akademik çalışmalarda ortaya konulmuş bir gerçektir. Çalışanın verimliliğinin artırılması ve üretilen hizmetin kalitesinin geliştirilmesi ile emeğin karşılığında elde edilen kazanç doğrudan ilişkili olarak görülmektedir. Benzer statülere sahip ve birbirine eşit sayılabilecek görevlerde çalışan bireylere orantılı ücretler verilmesi örgütsel adaletin bir gereğidir. Ancak kamuda; hizmetlerin çeşitliliği, çalışan sayısının fazlalığı, kurum sayısının çok olması gibi nedenler ücret dengesinin sağlanmasını güçleştirmektedir. Karşılaştırmalı çalışmalarda ücret adaletsizliğinden en çok etkilenen gruplardan birinin akademisyenler olduğu görülmektedir. Gelir adaletsizliğini ortadan kaldırmak ve cumhuriyetin kuruluşunun 100 yılında, 2023 vizyonuna ilişkin belirlenen iddialı hedeflere ulaşabilmek için yetenekli bireyleri akademisyenliğe özendirmek gerekmektedir. Ancak ulusal bazda kamu çalışanları arasında bir karşılaştırma yapıldığında üniversitede görev yapmakta olan öğretim elemanlarının özellikle son yıllarda diğer çalışanlara oranla yıllık ücret artışlarından yeterince yararlanamadığı, bu durumun akademisyenlik mesleğinden uzaklaşmalara neden olduğu öne sürülmektedir. Uluslararası bazda yapılan karşılaştırma yapıldığında ise, Türkiye’deki kamu üniversitelerinde görev yapmakta olan akademisyenlerin aldıkları ücretin ortalamaların altında olduğuna işaret edilmektedir. Bu çalışmada Türkiye’de kamu üniversitelerinde görev yapmakta olan akademisyenlerin aylık ücretlerinin mevcut durumuna ve yıllar içindeki değişimine yer verilecek, üniversite öğretim elemanlarının aylık ücretleri ve diğer kamu çalışanları arasında bu açıdan yapılan karşılaştırmalarla birlikte, Türkiye ile diğer ülkelerdeki üniversitelerde görev yapan akademisyenlerin aylık ücretleri mevcut durumu tartışılmaktadır.

Full Text Available Illegal immigration could be defined as a pathology of migration (which is a much broader, positive and needed phenomenon. It is a phenomenon of relevant historical importance; in particular, European history has been marked by many waves of migration, sometimes of whole populations. Unfortunately, the problem of illegal immigration is still very much present in today’s society, touching certain countries in particular, such as Italy, which suffers immigration from sub-Saharan Africa and the Balkan area.

Full Text Available In 1980s, there were significant thought shifts in cultural, economical, social and political areas. These changes have raised the question if different applications can be used in education system. In addition to this, by transferring the state's commercial activities to the private sector, people started to discuss if it is possible to transfer educational activities to private sector. The purpose of this study is to handle the concept of privatization which has been widely used in various countries, to examine the relationship between privatization and financing education, to look through the examples of privatization of education in different countries. Education, whose input and output is human, is an important branch of service. Training well-equipped individuals will raise the welfare of society. Better training of individuals depends on effective performance of the schools within the education system. This study includes a general framework about the application of privatization in education in different countires, the place of state and private sector in financing education. Also it has opinions from supporters and opponents of privatization. Increasing the participation of private sector in education, which is one of the key issues in the society, may ease the burden on the state. The important point here is that operation of the private sector should not harm the social justice in the society and quality in the education sysytem. A great number of universities from America, United Kingdom, Japan, where private sector is very active in education, took place in the top 100 universities in the world. In the same top 100 universities list there is no university from Turkey. This fact shows the necessity of new reforms in Turkish education system. Privatization in education can be considered as an alternative way to solve the quality problems of our schools. 1980’li yıllar pek çok ülkede kültürel, ekonomik, sosyal yaşam ile politika alanında önemli düşünce değişimlerin meydana geldiği bir dönem olmuştur. Bu değişimler toplumun hayatında önemli bir yere sahip olan eğitim sisteminde de değişik uygulamaların uygulanıp uygulanamayacağı sorusunu gündeme getirmiştir. Bu çalışma ile ekonomi alanında pek çok ülkede yaygın bir şekilde kullanılan özelleştirme kavramını ele almak, eğitimde özelleştirme ve finansman ilişkisini incelemek, eğitimde özelleştirmenin dünyadaki örneklerine göz atmak amaçlanmıştır. Eğitim insana yatırım yapan ve çıktısı yine insan olan önemli bir hizmet koludur. Devletin iyi eğitimli bireyler yetiştirmesi toplumun kalkınmasını sağlayacaktır. Bireylerin iyi yetiştirilmesi işi eğitim sistemi içinde faaliyet gösteren okulların etkili performanslarına bağlıdır. Bu çalışmada eğitimde özelleştirme uygulamalarının değişik ülkelerde gerçekleşme biçimine, eğitimin finansmanında devletin ve özel sektörün konumuna, eğitimde özelleştirmeyi destekleyenlerin ve karşı çıkanların görüşlerine yer verilmiştir. Eğitim gibi önemli bir konuda özel sektörün etkinliğini artırması devletin yükünü hafifletebilir. Burada dikkat edilecek husus özel kesimin daha fazla eğitim alanında faaliyet göstermesini sağlarken, eğitim kalitesinden ödün vermeden, toplumdaki sosyal adalet duygusunu incitmeden adımlar atabilmektir. Dünyadaki en iyi yüz üniversite sıralamasında özelleştirme uygulamalarının büyük ölçüde uygulandığı Amerika, İngiltere, Japonya gibi ülkelerden pek çok üniversitenin bulunması dikkat çekici bir durumdur. Aynı listeye Türkiye’den hiçbir üniversitenin girememiş olması da eğitim sisteminin yapısında yeniden yapılanmanın ne kadar büyük bir ihtiyaç olduğunu göstermektedir. Bu bağlamda özelleştirme eğitimde ülkemiz okullarının yaşadığı nitelik sorununa alternatif bir çözüm yolu geliştirmeye yardımcı olabilir.

Full Text Available Lucrarea de față se concentrează asupra unei opere de maturitate a filozofului german Arthur Schopenhauer, Aforisme asupra înțelepciunii în viață, și asupra singurei versiuni românești a acesteia, realizate de Titu Maiorescu la sfîrșitul secolului al XIX-lea. Existența a cinci variante ale versiunii românești, publicate de traducătorul însuși de-a lungul a patru decenii, reprezintă o dovadă clară a faptului că transpunerea în românește a acestui text de filozofie practică a incumbat o serie întreagă de dificultăți de traducere. Urmărind modul în care Titu Maiorescu a încercat să rezolve aceste dificultăți, prin adoptarea anumitor soluții traductologice, am realizat o analiză a acestora, din perspectivă lingvistică, cercetarea urmînd concomitent două direcții: contrastivă (rezultată din supra- punerea textului-sursă și a textului-țintă și diacronică (urmărind intervențiile realizate de același traducător asupra propriului text, la intervale de timp diferite. Demersul de analiză lingvistică a traducerii unui text filozofic ni s-a părut util nu doar studiului nostru, ci și viitorilor eventuali traducători ai Aforismelor, a căror intenție ar putea fi aceea de a adapta discursul versiunii românești a lui Titu Maiorescu la limba română contemporană, ținînd seama de evoluția evidentă a acesteia și, mai ales, a componentei sale de limbaj filozofic.

Full Text Available This article is based on a comparative analysis of Russia and US’s experience of participation in international cooperation in the field of trans-boundary water management. The author showcases the work of Russian-Estonian Commission for Protection and Rational Use of Trans-Boundary Waters and the US-Canadian International Joint Commission. The Russian-Estonian Commission works in accordance with the principle of intergovernmentalism, whereas transnationalism is the founding principle of the International Joint Commission in North America. Though the Russian-Estonian Commission is more efficient in water quality improvement in its area of responsibility, it is early still to claim that intergovernmental cooperation is more effective than transnational cooperation. However, it gives a reason to question the conclusions of the proponents of transnationalism in the international relations theory, who claim that the latter is more efficient. Practical significance of this paper is in the proposed recommendations for further modernization of international cooperation in the field of trans-boundary water management.

Full Text Available Considering that NATO, EU and other organizations tend to include public diplomacy elements in their official documents and strategies, we can say that states are no longer the exclusive actors in this field. Through this paper, I seek to identify some similarities and differences between NATO and EU’s public diplomacy. In this research I will also study how much of their soft power capabilities these organizations use, if they are used in order to influence rather internal than external audiences and if we can talk about elements of public diplomacy with involvements for development. Beyond these aspects, I will take into account the fact that Philip Seib claims that NATO should focus on using soft power in order to justify its hard power and try to see if there are differences in the goals that NATO and the EU target to reach through the implementation of some public diplomacy strategies.

Full Text Available The theoretical and pragmatic potential of the constitutional regulations and the comparative analysis of the peculiarities related to the normative fixing and the ways of implementing the local public power in the CIS countries, which have a common historical past and similar trends on building national sovereign states, can serve as a confirmation of the institutionalization and the need for a specific form of public power called local power in a democratic society. The rationale for recognizing the local autonomy in the constitutions of the states is determined by the following circumstance, namely, the recognition of the local autonomy principle in the fundamental law of the states constitutes a guarantee that it will be developed and deepened into the national law. Without such a constitutional basis, the local autonomy cannot be successful. From this perspective, it is important to conduct a comparative study of the constitutional texts of the states because the national legislative systems governing this phenomenon are designed under the constitutional provisions. The modalities of placing the local power in the supreme laws differ from state to state. The comparative study of the constitutional texts was carried out based on the following criteria: a the inclusion and ensuring the local autonomy in the constitutional text; b the interpretation of the concept of local autonomy in the constitutional text; and c the approach and recognition of local autonomy.

Rapid development of terrestrial laser scanning (TLS) in recent years resulted in its recognition and implementation in many industries, including forestry and nature conservation. The use of the 3D TLS point clouds in the process of inventory of trees and stands, as well as in the determination of their biometric features (trunk diameter, tree height, crown base, number of trunk shapes), trees and lumber size (volume of trees) is slowly becoming a practice. In addition to the measurement precision, the primary added value of TLS is the ability to automate the processing of the clouds of points 3D in the direction of the extraction of selected features of trees and stands. The paper presents the original software (GNOM) for the automatic measurement of selected features of trees, based on the cloud of points obtained by the ground laser scanner FARO. With the developed algorithms (GNOM), the location of tree trunks on the circular research surface was specified and the measurement was performed; the measurement covered the DBH (l: 1.3m), further diameters of tree trunks at different heights of the tree trunk, base of the tree crown and volume of the tree trunk (the selection measurement method), as well as the tree crown. Research works were performed in the territory of the Niepolomice Forest in an unmixed pine stand (Pinussylvestris L.) on the circular surface with a radius of 18 m, within which there were 16 pine trees (14 of them were cut down). It was characterized by a two-storey and even-aged construction (147 years old) and was devoid of undergrowth. Ground scanning was performed just before harvesting. The DBH of 16 pine trees was specified in a fully automatic way, using the algorithm GNOM with an accuracy of +2.1%, as compared to the reference measurement by the DBH measurement device. The medium, absolute measurement error in the cloud of points - using semi-automatic methods "PIXEL" (between points) and PIPE (fitting the cylinder) in the FARO Scene 5.x., showed the error, 3.5% and 5.0%,.respectively The reference height was assumed as the measurement performed by the tape on the cut tree. The average error of automatic determination of the tree height by the algorithm GNOM based on the TLS point clouds amounted to 6.3% and was slightly higher than when using the manual method of measurements on profiles in the TerraScan (Terrasolid; the error of 5.6%). The relatively high value of the error may be mainly related to the small number of points TLS in the upper parts of crowns. The crown height measurement showed the error of +9.5%. The reference in this case was the tape measurement performed already on the trunks of cut pine trees. Processing the clouds of points by the algorithms GNOM for 16 analyzed trees took no longer than 10 min. (37 sec. /tree). The paper mainly showed the TLS measurement innovation and its high precision in acquiring biometric data in forestry, and at the same time also the further need to increase the degree of automation of processing the clouds of points 3D from terrestrial laser scanning.

Full Text Available There have been lots of debates about differences and similarities between 1929 depression that had deep impacts on the world economy; and 2008 global crisis known as the deepest crisis since 1929; in terms of their occurrence reasons and progress trends. One of those similarities is about the crises global dimension. For instance, both of the crises formed in the United States (US economy first and spread fast and afterwards affected the European and other economies. Other similarity is, both of the crisis started at finance sector firstly and expanded to real sector because of interdependence among countries. Normally effects of both crisis caused huge shrinkages in growth rates and huge increases in unemployment rates. Some of the differences are; nowadays there is much more knowledge and experience compared to past years to overcome economic crises, differences among external trade policies following the crisis and common behaviors of countries etc. This study aims to present the effects of 1929 Depression and 2008 Global Crisis on real and financial sector comparatively.

Full Text Available The article uses the ecoprotective function effectiveness index (GEF to identify how far the changes in the management practices in the last 20 years had an impact on the capacity of forest ecosystem to provide optimal functions. The study was carried out in Forest District Vama (Production Unit I Deia, Suceava County and employs an integrated methodology based on forest management plans, remote sensing tools and field inventory. The structural patterns of state and private forests have been compared in two periods (1990, 2014. The private forests integrated in the analysis have been restituted according to the law 18/1991 and have been for more than 20 years managed by the new forest owners. For the state forests, GEF was computed using structural characteristics of the stands obtained from the management plans. In the restituted forests, due to the lack of management plans, all the characteristics were obtained from field inventory. The study successfully identifies how the components of the index have changed and how this influenced the overall effectiveness of the ecoprotective functions. The changes in GEF index values in the state forests were influenced by natural evolution of the stands while in private forests by the anthropic and natural disturbances. For the state forests, the GEF index values showed a slight increase in 2014 comparatively to 1990. In the private forests the GEF index value for 2014 decreased with more than 5 points for more than one half of the area compared to 1990 (prior to forest restitution. The study argues the possibility to adapt the index as an efficient tool to assess such changes at a broader scale, as a decisional support in forest policy processes.

Full Text Available IC analysis is a method of sentence analysis first explicitly introduced by American linguist Leonard Bloomfield in his book, Language, in 1933, though the underlying principle is common both to the traditional practice of parsing and to many modern systems of grammatical analysis. In IC analysis, a sentence is divided up into major divisions or immediate constituents, and these constituents are in turn divided into further immediate constituents. This process continues until irreducible constituents are reached, i.e., until each constituent consists of only a word or meaningful part of a word. The important tests used to analyze the sentences are deletion, permutation, transformation, and substitution tests.The end result of an IC analysis is often presented in a visual diagrammatic form that reveals the hierarchical immediate constituent structure of a sentence Direkt bileşenler analiz metodu Amerikalı dil bilimci Leonard Bloomfield tarafından 1933 yılında sentaks alanında başlatılmış, daha sonraki yıllarda fonetik ve morfoloji alanlarında da uygulanmıştır. Bu analiz metodunun amacı tümce veya kelime gruplarının parçalanması ve tasnif edilmesi işleminden ibarettir. Tümcelerin parçalanması en küçük dil birimine kadar kademe kademe yapılmalı ve bileşenlerin sınıflandırılmasında ise ana öbeğe veya ana gövdeye daha yakın olan unsurlar ile ikincil öğeler analizin amacına uygun olarak belirtilmelidir. Bu işlemler yapılırken Yok Etme Testi, Yer Değiştirme Testi, Dönüştürme Testi, Yerine Koyma Testi gibi metotlardan faydalanılır. Bu prensipler çerçevesinde yapılan analizin sonuçları hiyerarşik yapıları göstermek için bir grafikle özetlenir

The extraordinarily rapid advances made in mathematics since World War II have resulted in analysis becoming an enormous organism spread ing in all directions. Gone for good surely are the days of the great French "courses of analysis" which embodied the whole of the "ana lytical" knowledge of the times in three volumes-as the classical work of Camille Jordan. Perhaps that is why present-day textbooks of anal ysis are disproportionately modest relative to the present state of the art. More: they have "retreated" to the state before Jordan and Goursat. In recent years the scene has been changing rapidly: Jean Dieudon ne is offering us his monumentel Elements d'Analyse (10 volumes) written in the spirit of the great French Course d'Analyse. To the best of my knowledge, the present book is the only one of its size: starting from scratch-from rational numbers, to be precise-it goes on to the theory of distributions, direct integrals, analysis on com plex manifolds, Kahler manifolds, the theory of sheave...

Ar Rika fault zone constitutes one of the two major parts of the NW-SE Najd fault system (NFS), which is one of the most prominent structural features located in the east of the center of the Arabian Shield, Saudi Arabia. By using Enhancement Thematic Mapper data (ETM+) and Principle Component Analysis (PCA), surface geological characteristics, distribution of rock types, and the different trends of linear features and faults are determined in the study area. First and second order magnetic gradients of the geomagnetic field at the North East of Wadi Ar Rika have been calculated in the frequency domain to map both surface and subsurface lineaments and faults. Lineaments as deduced from previous studies, suggest an extension of the NFS beneath the cover rocks in the study area. In the present study, integration of magnetic gradients and remote sensing analysis that resulted in different valuable derivative maps confirm the subsurface extension of some of the surface features. The 3D Euler deconvolution, the total gradient, and the tilt angle maps have been utilized to determine accurately the distribution of shear zones, the tectonic implications, and the internal structures of the terranes in the Ar Rika quadrangle in three dimensions.

Full Text Available Needs assessment in local public institutions was not very present so far in a sistematic manner in Romanian specialised literature on administrative reform. Current study uses interviews with candidates for a public administration master program to investigate civil servants motivation of pursuing graduate-level studies and their perception on current needs of the work in local public institutions. Motivation for pursuing graduate studies is located mainly on the need to update and diversify their professional knowledge, and not as much on promotion-related reasons. The perceived needs are related to management of public institutions, structure of information system, legislation and European integration, human resource management and public relations.

Lo anterior se hizo asumiendo tanto el cumplimiento de los supuestos subyacentes de los mecanismos de estimación como el incumplimiento de los mismos. Igualmente se analizó el comportamiento de los estimadores bajo diferentes escenarios de tamaño muestral. Se encontró que bajo un modelo correctamente especificado y tamaños muestrales superiores a 200 observaciones se cumplen las propiedades de insesgadez y consistencia, mientras que la incorrecta especificación de la distribución del proceso lleva a estimaciones sesgadas e inconsistentes; de igual forma se encontró que en tamaños muestrales pequeños y bajo modelos condicionales se pierden las propiedades que una buena especificación del proceso suele generar, y se halla aún más inestabilidad cuando la estimación es llevada a cabo con la metodología Probit.This paper develops an analysis of Multinomial models through simulation; this was done under correct and incorrect assumptions on the data generating process. Also, it was analyzed the performance of the models under different sample sizes. It was found that a correct specified model with samples of 200 or more observations achieves estimators which are unbiased and consistent, while incorrect assumptions about the data generating process causes biased and inconsistent estimators. On the other hand, conditional models with small sample sizes imply bad statistical properties, especially when Probit models are estimated.

Se administró la escala a 506 entrenadores y se realizó un análisis factorial confirmatorio. La validez nomológica se analizó a través de las relaciones de las variables con la satisfacción de necesidades básicas y la motivación autodeterminada. El modelo mostró un ajuste adecuado a los datos. El castigo percibido no correlacionó con el resto de variables de la escala, que sí mostraron correlaciones positivas entre ellas, hasta el punto de que el apoyo a la competencia y autonomía fueron escasamente diferenciadas, mostrando una correlación muy alta. Se verificaron relaciones positivas de todas las variables, excepto el castigo, con la satisfacción de necesidades y la motivación autodeterminada, siendo negativa solo en el caso del castigo. El castigo solo se relacionó negativamente con la motivación autodeterminada. Estas relaciones apoyaron los postulados de la Teoría de la Autodeterminación y los estudios realizados en atletas.

The article presents a preliminary database analysis regarding the technical condition of 94 portal frame buildings located in the mining area of Legnica-Głogów Copper District (LGOM), using the methodology of decision trees. The scope of the analysis was divided into two stages. The first one included creating a decision tree by a standard CART method, and determining the importance of individual damage indices in the values of the technical wear of buildings. The second one was based on verification of the created decision tree and the importance of these indices in the technical wear of buildings by means of a simulation of individual dendritic models using the method of random forest. The obtained results confirmed the usefulness of decision trees in the early stage of data analysis. This methodology allows to build the initial model to describe the interaction between variables and to infer about the importance of individual input variables. Celem prezentowanych w artykule badań było sprawdzenie możliwości pozyskiwania informacji na temat udziału uszkodzeń w zużyciu technicznym zabudowy terenu górniczego z wykorzystaniem metody drzew decyzyjnych. Badania przeprowadzono na podstawie utworzonej przez autorów bazy danych o stanie technicznym i uszkodzeniach 94 budynków typu halowego, usytuowanych na terenie górniczym Legnicko-Głogowskiego Okręgu Miedziowego (LGOM).

Grey logic is not another name for fuzzy logic. Grey logic--also called grey analysis or grey system theory--is a new technology, a group of techniques for system analysis and modeling. Like fuzzy logic, grey logic is useful in situations with incomplete and uncertain information. Grey analysis is particularly applicable in instances with very limited data and in cases with little system knowledge or understanding. In this paper, a summary of the basic concepts of grey analysis is provided, with descriptions of its application to several classes of problems. Calculations methods are provided for grey relation analysis, and for modeling and prediction using grey methods.

The article deals with interaction of segregated business ethics elements with service enterprises activity. To discover the interaction, business ethics has been differentiated to segregated elements and the influence of the segregated elements for main indexes of enterprises competitiveness discovered by correlation coefficients. Effective mana-gement is inseparable from ethics. The organization of ethical training in the company cannot just “wake” ethical awareness, and also of targeted individuals to shape their activities on matter-of-fact ethical justification, as modern ethics code object principles can be implemented not only for ethical training for staff, but also involving them in the company’s code of ethics for development. The study showed that in Lithuania, so far, very few companies have their own ethic codes and employees not only do not participate in the production, but also little wise twig about their purpose. Calculations showed, that business ethics have direct impact on the corporate profits, it is clear that ethics is only an aid in order to achieve its goal. Although the overall company’s revenue per year has increased substantially, ethical behavior may in itself be evocative. The strongest influence discovered was: commitment compliance with sales results, profit growth, and installation rates of innovations; guarantee of the reliable service information about earnings; infor-mation security assurance and leadership style for company’s image. Also, some problems of implementation of business ethics at service enterprises were discovered.

Full Text Available This study examines the concepts of speaking, writing, reading and listening called as basic language skills in mother tongue education in regard to the relationship of deep structure and surface structure. The first chapter provides information on the concepts of deep structure and surface structure originally developed by Port Royal Grammar School and brought to the agenda by the theory of Transformational Generative Grammar put forward by Noam Chomsky in 1960s. The second chapter analysed the skills of speaking, writing, reading and listening in the context of the relationship of deep structure and surface structure. The purpose of the study is to determine the decisive elements in the process of the training of basic language skills within the context of meaning and form relationships, which are two fundamental dimensions of the language, and to develop proposals for scheduling the process. In the analyses of the study, it has been revealed that the concepts of articulation, prosody phenomena, body language, productive vocabulary, receptive vocabulary, fluency, text type, spelling and punctuation, coherence, consistency, prior knowledge, word recognition, word discrimination ability, acquired knowledge, presupposition, implication are the elements that have an impact on the development of basic language skills within the context of deep structure and surface structure relationships. The concepts of articulation, prosody phenomena, body language, fluency, coherence, text type, word recognition, word discrimination ability, spelling and punctuation are directly linked to surface structure. On the other hand, the concepts of productive vocabulary, receptive vocabulary, consistency, prior knowledge, acquired knowledge, presupposition and implication are related to deep structure. It has been determined that the concept of fluency is related to all language skills

This book is primarily intended for undergraduates in mathematics, the physical sciences and engineering. It introduces students to most of the techniques forming the core component of courses in numerical analysis. The text is divided into eight chapters which are largely self-contained. However, with a subject as intricately woven as mathematics, there is inevitably some interdependence between them. The level of difficulty varies and, although emphasis is firmly placed on the methods themselves rather than their analysis, we have not hesitated to include theoretical material when we consider it to be sufficiently interesting. However, it should be possible to omit those parts that do seem daunting while still being able to follow the worked examples and to tackle the exercises accompanying each section. Familiarity with the basic results of analysis and linear algebra is assumed since these are normally taught in first courses on mathematical methods. For reference purposes a list of theorems used in the t...

This textbook is designed for a year-long course in real analysis taken by beginning graduate and advanced undergraduate students in mathematics and other areas such as statistics, engineering, and economics. Written by one of the leading scholars in the field, it elegantly explores the core concepts in real analysis and introduces new, accessible methods for both students and instructors. The first half of the book develops both Lebesgue measure and, with essentially no additional work for the student, general Borel measures for the real line. Notation indicates when a result holds only for Lebesgue measure. Differentiation and absolute continuity are presented using a local maximal function, resulting in an exposition that is both simpler and more general than the traditional approach. The second half deals with general measures and functional analysis, including Hilbert spaces, Fourier series, and the Riesz representation theorem for positive linear functionals on continuous functions with compact support....

Mineralogical and morphological characteristics of the mineral are presented. The kaolin sample was formed mainly by kaolinite, but other minor phases were also detected such as quartz, cristobalite, tridymite, and dolomite. The high content of volcanic glass detected, by optical microscopy, revealed an incomplete kaolinization process of the raw material. The reddish color of the kaolin was associated with the free iron content in the form of limonite [FeO(OH], which was determined by XANES. The influence of the particle size on the whiteness of kaolin was evaluated. Dilatometric analysis revealed a strong thermal expansion between 110 y 240 °C, which would difficult the use of this material in traditional ceramic applications. On the other hand the presence of glass and high temperature phases of SiO2, such as cristobalite and tridymite will favor its use in the cement industry.El caolín obtenido de Villa de Reyes, una región cercana a San Luis Potosí, México, fue caracterizado por las siguientes técnicas: difracción de rayos-X en polvos (DRX, microscopía óptica (MO, microscopía electrónica de barrido (MEB, fluorescencia de rayos-X (FRX, espectroscopía de absorción de rayos-X (XANES, análisis térmico (DTA/TGA, dilatometría (DIL y análisis químico.

The guiding principle of this presentation of ``Classical Complex Analysis'' is to proceed as quickly as possible to the central results while using a small number of notions and concepts from other fields. Thus the prerequisites for understanding this book are minimal; only elementary facts of calculus and algebra are required. The first four chapters cover the essential core of complex analysis: - differentiation in C (including elementary facts about conformal mappings) - integration in C (including complex line integrals, Cauchy's Integral Theorem, and the Integral Formulas) - sequences and series of analytic functions, (isolated) singularities, Laurent series, calculus of residues - construction of analytic functions: the gamma function, Weierstrass' Factorization Theorem, Mittag-Leffler Partial Fraction Decomposition, and -as a particular highlight- the Riemann Mapping Theorem, which characterizes the simply connected domains in C. Further topics included are: - the theory of elliptic functions based on...

We describe the subject of Cosmic Microwave Background (CMB) analysis - its past, present and future. The theory of Gaussian primary anisotropies, those arising from linear physics operating in the early Universe, is in reasonably good shape so the focus has shifted to the statistical pipeline which confronts the data with the theory: mapping, filtering, comparing, cleaning, compressing, forecasting, estimating. There have been many algorithmic advances in the analysis pipeline in recent years, but still more are needed for the forecasts of high precision cosmic parameter estimation to be realized. For secondary anisotropies, those arising once nonlinearity develops, the computational state of the art currently needs effort in all the areas: the Sunyaev-Zeldovich effect, inhomogeneous reionization, gravitational lensing, the Rees-Sciama effect, dusty galaxies. We use the Sunyaev-Zeldovich example to illustrate the issues. The direct interface with observations for these non-Gaussian signals is much more compl...

The Energy Policy and Conservation Act (EPCA) mandated that minimum energy efficiency standards be established for classes of refrigerators and refrigerator-freezers, freezers, clothes dryers, water heaters, room air conditioners, home heating equipment, kitchen ranges and ovens, central air conditioners, and furnaces. EPCA requires that standards be designed to achieve the maximum improvement in energy efficiency that is technologically feasible and economically justified. Following the introductory chapter, Chapter Two describes the methodology used in the economic analysis and its relationship to legislative criteria for consumer product efficiency assessment; details how the CPES Value Model systematically compared and evaluated the economic impacts of regulation on the consumer, manufacturer and Nation. Chapter Three briefly displays the results of the analysis and lists the proposed performance standards by product class. Chapter Four describes the reasons for developing a baseline forecast, characterizes the baseline scenario from which regulatory impacts were calculated and summarizes the primary models, data sources and assumptions used in the baseline formulations. Chapter Five summarizes the methodology used to calculate regulatory impacts; describes the impacts of energy performance standards relative to the baseline discussed in Chapter Four. Also discussed are regional standards and other program alternatives to performance standards. Chapter Six describes the procedure for balancing consumer, manufacturer, and national impacts to select standard levels. Details of models and data bases used in the analysis are included in Appendices A through K.

In 1943, while in charge of Columbia University's Statistical Research Group, Abraham Wald devised Sequential Design, an innovative statistical inference system. Because the decision to terminate an experiment is not predetermined, sequential analysis can arrive at a decision much sooner and with substantially fewer observations than equally reliable test procedures based on a predetermined number of observations. The system's immense value was immediately recognized, and its use was restricted to wartime research and procedures. In 1945, it was released to the public and has since revolutio

This lively introductory text exposes the student to the rewards of a rigorous study of functions of a real variable. In each chapter, informal discussions of questions that give analysis its inherent fascination are followed by precise, but not overly formal, developments of the techniques needed to make sense of them. By focusing on the unifying themes of approximation and the resolution of paradoxes that arise in the transition from the finite to the infinite, the text turns what could be a daunting cascade of definitions and theorems into a coherent and engaging progression of ideas. Acutely aware of the need for rigor, the student is much better prepared to understand what constitutes a proper mathematical proof and how to write one. Fifteen years of classroom experience with the first edition of Understanding Analysis have solidified and refined the central narrative of the second edition. Roughly 150 new exercises join a selection of the best exercises from the first edition, and three more project-sty...

Full Text Available This paper presents an analysis of the damage propagation features of the pore structure of natural pumice lightweight aggregate concrete (LWC under freeze-thaw cyclic action. After freeze-thaw cycling, we conducted nuclear magnetic resonance (NMR tests on the concrete and acquired the porosity, distribution of transverse relaxation time T2, and magnetic resonance imaging (MRI results. The results showed the following. The T2 distribution of the LWC prior to freeze-thaw cycling presented four peaks representative of a preponderance of small pores. After 50, 100, 150, and 200 freeze-thaw cycles, the total area of the T2 spectrum and the porosity increased significantly. The MRI presented the changing spatial distribution of pores within the LWC during freeze-thaw cycling. Ultrasonic testing technology was applied simultaneously to analyze the NMR results, which verified that the new NMR technology demonstrated high accuracy and practicability for research regarding freeze-thaw concrete damage.En este trabajo se analiza la propagación de los daños que se producen en la estructura porosa de hormigón aligerado a base de piedra pómez natural sometido a la acción cíclica de hielo-deshielo. Después de realizarse los ensayos de hielo-deshielo, el hormigón se analizó mediante resonancia magnética nuclear (RMN, determinándose la porosidad y la distribución del tiempo de relajación transversal, T2, y registrándose las imágenes captadas por resonancia magnética. De acuerdo con los resultados obtenidos, antes de los ciclos de hielo-deshielo la distribución de T2 del hormigón aligerado presentaba cuatro picos, indicativos de un predominio de poros pequeños. Después de que se sometiera a 50, 100, 150, y 200 ciclos, se observó un aumento importante tanto de la porosidad como de la superficie total del espectro de T2.

An evaluation is made of the suitability of analytical and statistical sampling methods for making uncertainty analyses. The adjoint method is found to be well-suited for obtaining sensitivity coefficients for computer programs involving large numbers of equations and input parameters. For this purpose the Latin Hypercube Sampling method is found to be inferior to conventional experimental designs. The Latin hypercube method can be used to estimate output probability density functions, but requires supplementary rank transformations followed by stepwise regression to obtain uncertainty information on individual input parameters. A simple Cork and Bottle problem is used to illustrate the efficiency of the adjoint method relative to certain statistical sampling methods. For linear models of the form Ax=b it is shown that a complete adjoint sensitivity analysis can be made without formulating and solving the adjoint problem. This can be done either by using a special type of statistical sampling or by reformulating the primal problem and using suitable linear programming software.

A good part of matrix theory is functional analytic in spirit. This statement can be turned around. There are many problems in operator theory, where most of the complexities and subtleties are present in the finite-dimensional case. My purpose in writing this book is to present a systematic treatment of methods that are useful in the study of such problems. This book is intended for use as a text for upper division and gradu ate courses. Courses based on parts of the material have been given by me at the Indian Statistical Institute and at the University of Toronto (in collaboration with Chandler Davis). The book should also be useful as a reference for research workers in linear algebra, operator theory, mathe matical physics and numerical analysis. A possible subtitle of this book could be Matrix Inequalities. A reader who works through the book should expect to become proficient in the art of deriving such inequalities. Other authors have compared this art to that of cutting diamonds. One first has to...

Full Text Available Se analizó la relevancia de considerar la interfase aire-pintura en el proceso de igualación del color de una muestra y la importancia de tener una mejor caracterización de las pinturas que conforman la base de datos que se utiliza para reproducir el color de dicha muestra. El procedimiento de igualación del color en pinturas se basa en la teoría de Kubelka-Munk, en la cual, se presupone que el medio incidente es el mismo que el polímero de la pintura. El análisis se realizó igualando el color de una muestra mezclando pinturas coloreadas con un solo pigmento a una pintura blanca, y mezclando pinturas coloreadas con un solo pigmento a una pintura blanca formulada con pigmentos Ti02, de la cual se conocen los valores de K y S. Los cálculos fueron realizados con ayuda del software Mathemática 5.0. Se encontró que las coordenadas de color son sensibles a la interfase aire-pintura y que posiblemente un conocimiento más detallado de la formulación de pinturas permita obtener mejores resultados en la igualación del color.The relevance of considering the air-paint interface in the color matching process of a sample and the importance of having a better characterization of the paintings that make up the datábase that is used to reproduce the color of the sample is analyzed. The procedure for color matching paints, whose formulation is unknown, is based on the Kubelka-Munk theory, which assumes that the incident médium is the same as the polymer of the paint. The analysis was performed by matching the sample's color by mixing colored paints with a single pigment to a white paint, mixing paint and colored with a single pigment to a white paint made with pigments Ti02, for which the valúes of K and S are known. Calculations were performed using the software Mathemática 5.0.

Introducción: actualmente, el uso de Internet como fuente de información sobre temas de salud, y más concretamente sobre trastornos alimentarios, está aumentando enormemente. Sin embargo, al no existir una regulación precisa, la información disponible puede variar en calidad y fiabilidad. Objectivo: el objetivo del presente trabajo fue determinar tanto la calidad general como la información contenida en las páginas web sobre obesidad y trastornos de la alimentación más visitadas en España. Métodos: se introdujeron consecutivamente los términos ‘obesidad’, ‘anorexia’ y ‘bulimia’ en el buscador Google®. La calidad general de las páginas web se analizó mediante dos test, la certificación internacional HonCode ® y el test de Bermúdez-Tamayo et al.; la calidad de la información se analizó específicamente con el test DISCERN. Resultados: no observamos diferencias significativas en la calidad general entre las diferentes patologías estudiadas (p = 0,197), aunque las páginas web sobre anorexia obtuvieron las menores puntuaciones. Además, todas las páginas web mostraron deficiencias significativas respecto a la calidad de la información (p = 0,032). No obstante, las páginas sobre obesidad mostraron mayor calidad que las de anorexia. Discusión: la calidad general de las páginas sobre trastornos nutricionales es moderada, pero la calidad de la información que contienen es bastante deficiente. Hay que destacar que las páginas web sobre anorexia mostraron tanto la peor calidad como la peor información.

Full Text Available Tourism climatology is a popular field of study that deals with the relationship between tourism and climate through approaches such as applied climatology and human biometeorology. One of the subjects studied most in this field is the evaluation of bioclimatic comfort conditions. In recent years, inferences of this sort have been able to be made easily by use of certain indices. This study aims at evaluating and analyzing the bioclimatic comfort conditions of Artvin province by use of GIS. Within the scope of the research aim, monthly values belonging to SET*, PET, PMV, TCI, THI and SSI indices were calculated by use of meteorological data. SET*, PET, and PMV indices were determined via RayMan 1.2 while TCI, THI, and SSI indices were ascertained through Microsoft Excel 2013 supported analyses of various formulas. The obtained values were analyzed through GIS techniques. Also, statistical methods were utilized to make the research findings more meaningful. All in all, the province was seen to have comfortable conditions. This is because; the comfortable (1 class (68.9% covers a wider area than uncomfortable (0 class (31.1% in the province. Bioclimatic comfort classes are shaped by geographical position, elevation, and topography in Artvin province. Valleys with an elevation of less than 2000 m and coastal area are comfortable while mountainous areas (Rize, Kaçkar, Karçal, and Yalnızçam mounts with a higher elevation are uncomfortable. The results of one-way analysis of variance (one-sample t-test show that bioclimatic conditions have not been taken into consideration much during the planning of tourism accommodation facilities set up in Artvin province. This study evidences that GIS techniques are efficient in research on tourism climatology or bioclimatology and thus they may be used widely.

NASA s Constellation Program employs a strategic analysis methodology in providing an integrated analysis capability of Lunar exploration scenarios and to support strategic decision-making regarding those scenarios. The strategic analysis methodology integrates the assessment of the major contributors to strategic objective satisfaction performance, affordability, and risk and captures the linkages and feedbacks between all three components. Strategic analysis supports strategic decision making by senior management through comparable analysis of alternative strategies, provision of a consistent set of high level value metrics, and the enabling of cost-benefit analysis. The tools developed to implement the strategic analysis methodology are not element design and sizing tools. Rather, these models evaluate strategic performance using predefined elements, imported into a library from expert-driven design/sizing tools or expert analysis. Specific components of the strategic analysis tool set include scenario definition, requirements generation, mission manifesting, scenario lifecycle costing, crew time analysis, objective satisfaction benefit, risk analysis, and probabilistic evaluation. Results from all components of strategic analysis are evaluated a set of pre-defined figures of merit (FOMs). These FOMs capture the high-level strategic characteristics of all scenarios and facilitate direct comparison of options. The strategic analysis methodology that is described in this paper has previously been applied to the Space Shuttle and International Space Station Programs and is now being used to support the development of the baseline Constellation Program lunar architecture. This paper will present an overview of the strategic analysis methodology and will present sample results from the application of the strategic analysis methodology to the Constellation Program lunar architecture.

While the planning and implementation of usability evaluations are well described in the literature, the analysis of the evaluation data is not. We present interviews with 11 usability professionals on how they conduct analysis, describing the resources, collaboration, creation of recommendations......, and prioritization involved. The interviews indicate a lack of structure in the analysis process and suggest activities, such as generating recommendations, that are unsupported by existing methods. We discuss how to better support analysis, and propose four themes for future research on analysis in usability...

VISPA is a development environment for high energy physics analyses which enables physicists to combine graphical and textual work. A physics analysis cycle consists of prototyping, performing, and verifying the analysis. The main feature of VISPA is a multipurpose window for visual steering of analysis steps, creation of analysis templates, and browsing physics event data at different steps of an analysis. VISPA follows an experiment-independent approach and incorporates various tools for steering and controlling required in a typical analysis. Connection to different frameworks of high energy physics experiments is achieved by using different types of interfaces. We present the look-and-feel for an example physics analysis at the LHC and explain the underlying software concepts of VISPA.

The ATLAS Analysis Model is a continually developing vision of how to reconcile physics analysis requirements with the ATLAS offline software and computing model constraints. In the past year this vision has influenced the evolution of the ATLAS Event Data Model, the Athena software framework, and physics analysis tools. These developments, along with the October Analysis Model Workshop and the planning for CSC analyses have led to a rapid refinement of the ATLAS Analysis Model in the past few months. This article introduces some of the relevant issues and presents the current vision of the future ATLAS Analysis Model. Event Data Model The ATLAS Event Data Model (EDM) consists of several levels of details, each targeted for a specific set of tasks. For example the Event Summary Data (ESD) stores calorimeter cells and tracking system hits thereby permitting many calibration and alignment tasks, but will be only accessible at particular computing sites with potentially large latency. In contrast, the Analysis...
Multivariate analysis with LISREL
Jöreskog, Karl G; Y Wallentin, Fan
2016-01-01
This book traces the theory and methodology of multivariate statistical analysis and shows how it can be conducted in practice using the LISREL computer program. It presents not only the typical uses of LISREL, such as confirmatory factor analysis and structural equation models, but also several other multivariate analysis topics, including regression (univariate, multivariate, censored, logistic, and probit), generalized linear models, multilevel analysis, and principal component analysis. It provides numerous examples from several disciplines and discusses and interprets the results, illustrated with sections of output from the LISREL program, in the context of the example. The book is intended for masters and PhD students and researchers in the social, behavioral, economic and many other sciences who require a basic understanding of multivariate statistical theory and methods for their analysis of multivariate data. It can also be used as a textbook on various topics of multivariate statistical analysis.

This article documents how log analysis can inform qualitative studies concerning the usage of web-based information systems (WIS). No prior research has used http log files as data to study collaboration between multiple users in organisational settings. We investigate how to perform http log...... analysis; what http log analysis says about the nature of collaborative WIS use; and how results from http log analysis may support other data collection methods such as surveys, interviews, and observation. The analysis of log files initially lends itself to research designs, which serve to test...... hypotheses using a quantitative methodology. We show that http log analysis can also be valuable in qualitative research such as case studies. The results from http log analysis can be triangulated with other data sources and for example serve as a means of supporting the interpretation of interview data...

Su prevalencia es del 3-5% en personas mayores de 65 años y su incidencia de 1-2% al año en la población general; se caracteriza por alteraciones progresivas en la memoria, el lenguaje, la atención, el comportamiento y la presencia de déficit visoespaciales. Objetivo: hacer un análisis descriptivo-comparativo de una muestra poblacional con demencia tipo Alzheimer, en especial una descripción fenomenológica de las alteraciones del lenguaje presentes en esa población. Métodos: como criterios de inclusión se usaron: diagnóstico de demencia tipo Alzheimer, dominancia manual derecha, escolaridad superior a quinto de primaria y capacidad para rendir las pruebas propuestas. Se comparó el rendimiento en las subpruebas de lenguaje del examen mínimo del estado mental (MMSE; en denominación y fluidez semántica y fonológica y se analizó el deterioro lingüístico en dos estadios de la demencia tipo Alzheimer. Resultados: en el estadio leve se evidencian déficit ligeros en todas las pruebas. Sin embargo los dominios con rendimiento más bajo fueron la fluidez fonológica y semántica. En el estadio moderado se evidenciaron diferencias en el rendimiento;las tareas de denominación, fluidez semántica y fluidez fonológica tuvieron rendimiento más bajo. Conclusiones: el lenguaje es un dominio que suele comprometerse en la demencia tipo Alzheimer. Los resultados reflejan el deterioro progresivo de la habilidad lingüística, manifiesto en un amplio rango de frecuencia entre el estadio leve y el moderado de la demencia. Existe un perfil similar de deterioro para los estadios leve y moderado con patrones independientes en las pruebas específicas.Background: Alzheimer disease explains near 70% of all instances of dementia and its prevalence in 65 years old population is 3-5% while incidence is near 1-2 % per year in general population.

NASA trend analysis procedures
1993-01-01
This publication is primarily intended for use by NASA personnel engaged in managing or implementing trend analysis programs. 'Trend analysis' refers to the observation of current activity in the context of the past in order to infer the expected level of future activity. NASA trend analysis was divided into 5 categories: problem, performance, supportability, programmatic, and reliability. Problem trend analysis uncovers multiple occurrences of historical hardware or software problems or failures in order to focus future corrective action. Performance trend analysis observes changing levels of real-time or historical flight vehicle performance parameters such as temperatures, pressures, and flow rates as compared to specification or 'safe' limits. Supportability trend analysis assesses the adequacy of the spaceflight logistics system; example indicators are repair-turn-around time and parts stockage levels. Programmatic trend analysis uses quantitative indicators to evaluate the 'health' of NASA programs of all types. Finally, reliability trend analysis attempts to evaluate the growth of system reliability based on a decreasing rate of occurrence of hardware problems over time. Procedures for conducting all five types of trend analysis are provided in this publication, prepared through the joint efforts of the NASA Trend Analysis Working Group.

Fundamentals of functional analysis
Farenick, Douglas
2016-01-01
This book provides a unique path for graduate or advanced undergraduate students to begin studying the rich subject of functional analysis with fewer prerequisites than is normally required. The text begins with a self-contained and highly efficient introduction to topology and measure theory, which focuses on the essential notions required for the study of functional analysis, and which are often buried within full-length overviews of the subjects. This is particularly useful for those in applied mathematics, engineering, or physics who need to have a firm grasp of functional analysis, but not necessarily some of the more abstruse aspects of topology and measure theory normally encountered. The reader is assumed to only have knowledge of basic real analysis, complex analysis, and algebra. The latter part of the text provides an outstanding treatment of Banach space theory and operator theory, covering topics not usually found together in other books on functional analysis. Written in a clear, concise manner,...

Our analysis program LULU has proven very useful in all stages of experiment analysis, from prerun detector debugging through final data reduction. It has solved our problem of having arbitrary word length events and is easy enough to use that many separate experimenters are now analyzing with LULU. The ability to use the same software for all stages of experiment analysis greatly eases the programming burden. We may even get around to making the graphics elegant someday.

Robust Sparse Analysis Regularization
Vaiter, Samuel; Dossal, Charles; Fadili, Jalal
2011-01-01
This paper studies the properties of L1-analysis regularization for the resolution of linear inverse problems. Most previous works consider sparse synthesis priors where the sparsity is measured as the L1 norm of the coefficients that synthesize the signal in a given dictionary. In contrast, the more general analysis regularization minimizes the L1 norm of the correlations between the signal and the atoms in the dictionary. The corresponding variational problem includes several well-known regularizations such as the discrete total variation and the fused lasso. We first prove that a solution of analysis regularization is a piecewise affine function of the observations. Similarly, it is a piecewise affine function of the regularization parameter. This allows us to compute the degrees of freedom associated to sparse analysis estimators. Another contribution gives a sufficient condition to ensure that a signal is the unique solution of the analysis regularization when there is no noise in the observations. The s...

The Norwegian Mapping Authority (NMA) has during the last few years had a close cooperation with Norwegian Defence Research Establishment (FFI) in the analysis of space geodetic data using the GEOSAT software. In 2012 NMA has taken over the full responsibility for the GEOSAT software. This implies that FFI stopped being an IVS Associate Analysis Center in 2012. NMA has been an IVS Associate Analysis Center since 28 October 2010. NMA's contributions to the IVS as an Analysis Centers focus primarily on routine production of session-by-session unconstrained and consistent normal equations by GEOSAT as input to the IVS combined solution. After the recent improvements, we expect that VLBI results produced with GEOSAT will be consistent with results from the other VLBI Analysis Centers to a satisfactory level.
IAC - INTEGRATED ANALYSIS CAPABILITY
Frisch, H. P.
1994-01-01
The objective of the Integrated Analysis Capability (IAC) system is to provide a highly effective, interactive analysis tool for the integrated design of large structures. With the goal of supporting the unique needs of engineering analysis groups concerned with interdisciplinary problems, IAC was developed to interface programs from the fields of structures, thermodynamics, controls, and system dynamics with an executive system and database to yield a highly efficient multi-disciplinary system. Special attention is given to user requirements such as data handling and on-line assistance with operational features, and the ability to add new modules of the user's choice at a future date. IAC contains an executive system, a data base, general utilities, interfaces to various engineering programs, and a framework for building interfaces to other programs. IAC has shown itself to be effective in automatic data transfer among analysis programs. IAC 2.5, designed to be compatible as far as possible with Level 1.5, contains a major upgrade in executive and database management system capabilities, and includes interfaces to enable thermal, structures, optics, and control interaction dynamics analysis. The IAC system architecture is modular in design. 1) The executive module contains an input command processor, an extensive data management system, and driver code to execute the application modules. 2) Technical modules provide standalone computational capability as well as support for various solution paths or coupled analyses. 3) Graphics and model generation interfaces are supplied for building and viewing models. Advanced graphics capabilities are provided within particular analysis modules such as INCA and NASTRAN. 4) Interface modules provide for the required data flow between IAC and other modules. 5) User modules can be arbitrary executable programs or JCL procedures with no pre-defined relationship to IAC. 6) Special purpose modules are included, such as MIMIC (Model

There is a large volume of literature on the research use of gait analysis, but evidence on its clinical routine use supports a favorable cost-benefit ratio in a limited number of conditions. Initially gait analysis was introduced to clinical practice to improve the management of children with cerebral palsy. However, there is good evidence to extend its use to patients with various upper motor neuron diseases, and to lower limb amputation. Thereby, the methodology for properly conducting and interpreting the exam is of paramount relevance. Appropriateness of gait analysis prescription and reliability of data obtained are required in the clinical environment. This paper provides an overview on guidelines for managing a clinical gait analysis service and on the principal clinical domains of its application: cerebral palsy, stroke, traumatic brain injury and lower limb amputation.
Systems engineering and analysis
Blanchard, Benjamin S
2010-01-01
For senior-level undergraduate and first and second year graduate systems engineering and related courses. A total life-cycle approach to systems and their analysis. This practical introduction to systems engineering and analysis provides the concepts, methodologies, models, and tools needed to understand and implement a total life-cycle approach to systems and their analysis. The authors focus first on the process of bringing systems into being--beginning with the identification of a need and extending that need through requirements determination, functional analysis and allocation, design synthesis, evaluation, and validation, operation and support, phase-out, and disposal. Next, the authors discuss the improvement of systems currently in being, showing that by employing the iterative process of analysis, evaluation, feedback, and modification, most systems in existence can be improved in their affordability, effectiveness, and stakeholder satisfaction.

Full Text Available A Semantic-Cognitive Analysis of the Concept of Ukraine in the Speeches of B. Obama (2014 This article presents a semantic-cognitive analysis of the concept of Ukraine, verbally represented in the speeches of the American President, Barack Obama. The peculiarities of the President’s worldview are highlighted. The objective of the article is as follows. Firstly, it aims to demonstrate that the concept of Ukraine is verbally represented in the speeches of Obama. This means that Ukraine as a country, moving towards democracy despite the war with Russia, is an object of focus for American leaders. Secondly, the article suggests that there is a connection between the concept described, its pragmatic orientation and its cognitive processes. Thirdly, it describes the semantic peculiarities of the concept of Ukraine in the political speeches of the American leader, which are due to the role Ukraine plays in the local and regional context. Our research is based on the content-analysis of political speeches delivered by American President. The functional, communicative and pragmatic orientation of the speeches is highlighted. In line with the approaches of cognitive scholars, the article concludes that the concept of Ukraine is a complex semantic-cognitive structure that consists of core, transition zone and periphery. During the research for this article, fifteen speeches made by Obama in 2014 were analysed. This research presupposes the application of content analysis. It is relevant in the analysis of international relations with respect to the notions used by President Obama in his speeches delivered during 2014 in the relations between: the USA - Ukraine, Ukraine - Russia, the USA - Russia, and Europe - Ukraine.

Full Text Available La cuenca Cuyana forma parte del conjunto de cuencas triásicas desarrolladas en el antepaís andino de Argentina. El origen de esta estructura ha sido postulado como el resultado de esfuerzos extensionales. La atenuación cortical es un rasgo estructural característico de los paleo-rifts, aunque su identificación es a veces complicada por la cubierta sedimentaria y los eventos tectónicos posteriores. Con el objeto de contribuir a la interpretación geológica, se analizó el campo de gravedad medido sobre la misma. Para este estudio, los efectos de gravedad del relleno sedimentario de la depresión y de la raíz andina al oeste fueron calculados y luego removidos de las anomalías de gravedad observadas. Información sísmica de velocidades y espesores fueron incorporados para el cómputo del efecto de gravedad del relleno sedimentario. Un modelo isostático balanceado en la hipótesis de Airy sirvió para modelar el efecto de gravedad de la raíz andina. El filtrado de superficies de tendencia nos permitió establecer la existencia de máximos de gravedad sobre la cuenca propiamente dicha. Además, el análisis isostático en el concepto de Airy, postulando anti-raíces a nivel de Moho bajo la depresión, indicó un estado actual de leve sobrecompensación. En este sentido la cuenca debería, en lo futuro, subsidir para alcanzar el equilibrio. El modelado gravimétrico sobre dos secciones transversales en 33° 30' y 35° de latitud sur, en términos de la topografía de Moho, señalan que el Moho sería más somero bajo la cuenca. Estos resultados indican que un modelo que admite leve atenuación cortical actual para justificar los excesos de gravedad, es factible de ser postulado para la estructura cortical de la cuenca Cuyana.The Cuyo Basin is a part of the Triassic basin set developed in the Andean foreland of Argentina. The origin of this structure has been postulated as being the result of extensional stresses. Crustal thinning is a
Dynamics in Epistasis Analysis.

Finding regulatory relationships between genes, including the direction and nature of influence between them, is a fundamental challenge in the field of molecular genetics. One classical approach to this problem is epistasis analysis. Broadly speaking, epistasis analysis infers the regulatory relationships between a pair of genes in a genetic pathway by considering the patterns of change in an observable trait resulting from single and double deletion of genes. While classical epistasis analysis has yielded deep insights on numerous genetic pathways, it is not without limitations. Here, we explore the possibility of dynamic epistasis analysis, in which, in addition to performing genetic perturbations of a pathway, we drive the pathway by a time-varying upstream signal. We explore the theoretical power of dynamical epistasis analysis by conducting an identifiability analysis of Boolean models of genetic pathways, comparing static and dynamic approaches. We find that even relatively simple input dynamics greatly increases the power of epistasis analysis to discriminate alternative network structures. Further, we explore the question of experiment design, and show that a subset of short time-varying signals, which we call dynamic primitives, allow maximum discriminative power with a reduced number of experiments.
Meaning from curriculum analysis
Finegold, Menahem; Mackeracher, Dorothy
This paper reports on the analysis of science curricula carried out across Canada within the framework of the Second International Science Study (SISS). The organization of Canadian education in twelve autonomous educational jurisdictions is briefly described and problems are noted in relation to the analysis of curricula on a national scale. The international design for curriculum analysis is discussed and an alternative design, more suited to the diversity of science education in Canada, is introduced. The analysis of curriculum documents is described and three patterns which emerge from this analysis are identified. These derive from the concepts of commonality, specificity and prescriptiveness. Commonality relates to topics listed in curriculum guideline documents by a number of jurisdictions. Specificity refers to the richness of curriculum documents. Prescriptiveness is a measure of the extent to which jurisdictions do or do not make provision for local options in curriculum design. The Canadian analysis, using the concepts of the common curriculum, specificity and prescriptiveness, is described and research procedures are exemplified. Outcomes of curriculum analysis are presented in graphical form.

This paper briefly describes WASH 1400 and the Lewis report. It attempts to define basic concepts such as risk and risk analysis, common mode failure, and rare event. Several probabilistic models which go beyond the WASH 1400 methodology are introduced; the common characteristic of these models is that they recognize explicitly that risk analysis is time dependent whereas WASH 1400 takes a per demand failure rate approach which obscures the important fact that accidents are time related. Further, the presentation of a realistic risk analysis should recognize that there are various risks which compete with one another for the lives of the individuals at risk. A way of doing this is suggested.

Bayesian nonparametric data analysis
Müller, Peter; Jara, Alejandro; Hanson, Tim
2015-01-01
This book reviews nonparametric Bayesian methods and models that have proven useful in the context of data analysis. Rather than providing an encyclopedic review of probability models, the book’s structure follows a data analysis perspective. As such, the chapters are organized by traditional data analysis problems. In selecting specific nonparametric models, simpler and more traditional models are favored over specialized ones. The discussed methods are illustrated with a wealth of examples, including applications ranging from stylized examples to case studies from recent literature. The book also includes an extensive discussion of computational methods and details on their implementation. R code for many examples is included in on-line software pages.

Structural Reliability Consultants' computer program creates graphic plots showing the statistical parameters of glue laminated timbers, or 'glulam.' The company president, Dr. Joseph Murphy, read in NASA Tech Briefs about work related to analysis of Space Shuttle surface tile strength performed for Johnson Space Center by Rockwell International Corporation. Analysis led to a theory of 'consistent tolerance bounds' for statistical distributions, applicable in industrial testing where statistical analysis can influence product development and use. Dr. Murphy then obtained the Tech Support Package that covers the subject in greater detail. The TSP became the basis for Dr. Murphy's computer program PC-DATA, which he is marketing commercially.

Principles of Fourier analysis
Howell, Kenneth B
2001-01-01
Fourier analysis is one of the most useful and widely employed sets of tools for the engineer, the scientist, and the applied mathematician. As such, students and practitioners in these disciplines need a practical and mathematically solid introduction to its principles. They need straightforward verifications of its results and formulas, and they need clear indications of the limitations of those results and formulas.Principles of Fourier Analysis furnishes all this and more. It provides a comprehensive overview of the mathematical theory of Fourier analysis, including the development of Fourier series, "classical" Fourier transforms, generalized Fourier transforms and analysis, and the discrete theory. Much of the author''s development is strikingly different from typical presentations. His approach to defining the classical Fourier transform results in a much cleaner, more coherent theory that leads naturally to a starting point for the generalized theory. He also introduces a new generalized theory based ...

The present volume develops the theory of integration in Banach spaces, martingales and UMD spaces, and culminates in a treatment of the Hilbert transform, Littlewood-Paley theory and the vector-valued Mihlin multiplier theorem. Over the past fifteen years, motivated by regularity problems in evolution equations, there has been tremendous progress in the analysis of Banach space-valued functions and processes. The contents of this extensive and powerful toolbox have been mostly scattered around in research papers and lecture notes. Collecting this diverse body of material into a unified and accessible presentation fills a gap in the existing literature. The principal audience that we have in mind consists of researchers who need and use Analysis in Banach Spaces as a tool for studying problems in partial differential equations, harmonic analysis, and stochastic analysis. Self-contained and offering complete proofs, this work is accessible to graduate students and researchers with a background in functional an...

Quantification of categorical, or non-numerical, data is a problem that scientists face across a wide range of disciplines. Exploring data analysis in various areas of research, such as the social sciences and biology, Multidimensional Nonlinear Descriptive Analysis presents methods for analyzing categorical data that are not necessarily sampled randomly from a normal population and often involve nonlinear relations. This reference not only provides an overview of multidimensional nonlinear descriptive analysis (MUNDA) of discrete data, it also offers new results in a variety of fields. The first part of the book covers conceptual and technical preliminaries needed to understand the data analysis in subsequent chapters. The next two parts contain applications of MUNDA to diverse data types, with each chapter devoted to one type of categorical data, a brief historical comment, and basic skills peculiar to the data types. The final part examines several problems and then concludes with suggestions for futu...

Perspectives in shape analysis
Bruckstein, Alfred; Maragos, Petros; Wuhrer, Stefanie
2016-01-01
This book presents recent advances in the field of shape analysis. Written by experts in the fields of continuous-scale shape analysis, discrete shape analysis and sparsity, and numerical computing who hail from different communities, it provides a unique view of the topic from a broad range of perspectives. Over the last decade, it has become increasingly affordable to digitize shape information at high resolution. Yet analyzing and processing this data remains challenging because of the large amount of data involved, and because modern applications such as human-computer interaction require real-time processing. Meeting these challenges requires interdisciplinary approaches that combine concepts from a variety of research areas, including numerical computing, differential geometry, deformable shape modeling, sparse data representation, and machine learning. On the algorithmic side, many shape analysis tasks are modeled using partial differential equations, which can be solved using tools from the field of n...

This book provides the reader with the knowledge necessary for comprehension of the field of Intelligent Audio Analysis. It firstly introduces standard methods and discusses the typical Intelligent Audio Analysis chain going from audio data to audio features to audio recognition. Further, an introduction to audio source separation, and enhancement and robustness are given. After the introductory parts, the book shows several applications for the three types of audio: speech, music, and general sound. Each task is shortly introduced, followed by a description of the specific data and methods applied, experiments and results, and a conclusion for this specific task. The books provides benchmark results and standardized test-beds for a broader range of audio analysis tasks. The main focus thereby lies on the parallel advancement of realism in audio analysis, as too often today’s results are overly optimistic owing to idealized testing conditions, and it serves to stimulate synergies arising from transfer of ...
Longitudinal categorical data analysis
Sutradhar, Brajendra C
2014-01-01
This is the first book in longitudinal categorical data analysis with parametric correlation models developed based on dynamic relationships among repeated categorical responses. This book is a natural generalization of the longitudinal binary data analysis to the multinomial data setup with more than two categories. Thus, unlike the existing books on cross-sectional categorical data analysis using log linear models, this book uses multinomial probability models both in cross-sectional and longitudinal setups. A theoretical foundation is provided for the analysis of univariate multinomial responses, by developing models systematically for the cases with no covariates as well as categorical covariates, both in cross-sectional and longitudinal setups. In the longitudinal setup, both stationary and non-stationary covariates are considered. These models have also been extended to the bivariate multinomial setup along with suitable covariates. For the inferences, the book uses the generalized quasi-likelihood as w...

Materials analysis with ion beams exploits the interaction of ions with the electrons and nuclei in the sample. Among the vast variety of possible analytical techniques available with ion beams we will restrain to ion beam analysis with ion beams in the energy range from one to several MeV per mass unit. It is possible to use either the back-scattered projectiles (RBS – Rutherford Back Scattering) or the recoiled atoms itself (ERDA – Elastic Recoil Detection Analysis) from the elastic scattering processes. These techniques allow the simultaneous and absolute determination of stoichiometry and depth profiles of the detected elements. The interaction of the ions with the electrons in the sample produces holes in the inner electronic shells of the sample atoms, which recombine and emit X-rays characteristic for the element in question. Particle Induced X-ray Emission (PIXE) has shown to be a fast technique for the analysis of elements with an atomic number above 11.

The DOE Hydrogen Program is supporting research, development, and demonstration activities to overcome the barriers to the integration of hydrogen into the Nation`s energy infrastructure. Much work is required to gain acceptance of hydrogen energy system concepts and to develop them for implementation. A systems analysis database has been created that includes a formal documentation of technology characterization profiles and cost and performance information. Through a systematic and quantitative approach, system developers can understand and address important issues and thereby assure effective and timely commercial implementation. This project builds upon and expands the previously developed and tested pathway model and provides the basis for a consistent and objective analysis of all hydrogen energy concepts considered by the DOE Hydrogen Program Manager. This project can greatly accelerate the development of a system by minimizing the risk of costly design evolutions, and by stimulating discussions, feedback, and coordination of key players and allows them to assess the analysis, evaluate the trade-offs, and to address any emerging problem areas. Specific analytical studies will result in the validation of the competitive feasibility of the proposed system and identify system development needs. Systems that are investigated include hydrogen bromine electrolysis, municipal solid waste gasification, electro-farming (biomass gasifier and PEM fuel cell), wind/hydrogen hybrid system for remote sites, home electrolysis and alternate infrastructure options, renewable-based electrolysis to fuel PEM fuel cell vehicle fleet, and geothermal energy used to produce hydrogen. These systems are compared to conventional and benchmark technologies. Interim results and findings are presented. Independent analyses emphasize quality, integrity, objectivity, a long-term perspective, corporate memory, and the merging of technical, economic, operational, and programmatic expertise.

A stimulating introductory text, this volume examines many important applications of functional analysis to mechanics, fluid mechanics, diffusive growth, and approximation. Detailed enough to impart a thorough understanding, the text is also sufficiently straightforward for those unfamiliar with abstract analysis. Its four-part treatment begins with distribution theory and discussions of Green's functions. Essentially independent of the preceding material, the second and third parts deal with Banach spaces, Hilbert space, spectral theory, and variational techniques. The final part outlines the

The Design-through-Analysis Realization Team (DART) is chartered with reducing the time Sandia analysts require to complete the engineering analysis process. The DART system analysis team studied the engineering analysis processes employed by analysts in Centers 9100 and 8700 at Sandia to identify opportunities for reducing overall design-through-analysis process time. The team created and implemented a rigorous analysis methodology based on a generic process flow model parameterized by information obtained from analysts. They also collected data from analysis department managers to quantify the problem type and complexity distribution throughout Sandia's analyst community. They then used this information to develop a community model, which enables a simple characterization of processes that span the analyst community. The results indicate that equal opportunity for reducing analysis process time is available both by reducing the ''once-through'' time required to complete a process step and by reducing the probability of backward iteration. In addition, reducing the rework fraction (i.e., improving the engineering efficiency of subsequent iterations) offers approximately 40% to 80% of the benefit of reducing the ''once-through'' time or iteration probability, depending upon the process step being considered. Further, the results indicate that geometry manipulation and meshing is the largest portion of an analyst's effort, especially for structural problems, and offers significant opportunity for overall time reduction. Iteration loops initiated late in the process are more costly than others because they increase ''inner loop'' iterations. Identifying and correcting problems as early as possible in the process offers significant opportunity for time savings.

In this article an attempt to enhance the awareness of hedging use in discourse analysis and academic writing is made by analyzing hedges employed in two comparable texts. The discourse analysis is conducted from“content-oriented”hedges and“reader-oriented”hedges. The article suggests that hedging can dampen utterances and statements, weaken the force of what one says and show politeness to the listeners or readers, which varies from different discourse styles of various genres.

NASA/NESSUS 6.2c is a general-purpose, probabilistic analysis program that computes probability of failure and probabilistic sensitivity measures of engineered systems. Because NASA/NESSUS uses highly computationally efficient and accurate analysis techniques, probabilistic solutions can be obtained even for extremely large and complex models. Once the probabilistic response is quantified, the results can be used to support risk-informed decisions regarding reliability for safety-critical and one-of-a-kind systems, as well as for maintaining a level of quality while reducing manufacturing costs for larger-quantity products. NASA/NESSUS has been successfully applied to a diverse range of problems in aerospace, gas turbine engines, biomechanics, pipelines, defense, weaponry, and infrastructure. This program combines state-of-the-art probabilistic algorithms with general-purpose structural analysis and lifting methods to compute the probabilistic response and reliability of engineered structures. Uncertainties in load, material properties, geometry, boundary conditions, and initial conditions can be simulated. The structural analysis methods include non-linear finite-element methods, heat-transfer analysis, polymer/ceramic matrix composite analysis, monolithic (conventional metallic) materials life-prediction methodologies, boundary element methods, and user-written subroutines. Several probabilistic algorithms are available such as the advanced mean value method and the adaptive importance sampling method. NASA/NESSUS 6.2c is structured in a modular format with 15 elements.

The ATLAS experiment accumulated more than 140 PB of data during the first run of the Large Hadron Collider (LHC) at CERN. The analysis of such an amount of data for the distributed physics community is a challenging task. The Distributed Analysis (DA) system of the ATLAS experiment is an established and stable component of the ATLAS distributed computing operations. About half a million user jobs are daily running on DA resources, submitted by more than 1500 ATLAS physicists. The reliability of the DA system during the first run of the LHC and the following shutdown period has been high thanks to the continuous automatic validation of the distributed analysis sites and the user support provided by a dedicated team of expert shifters. During the LHC shutdown, the ATLAS computing model has undergone several changes to improve the analysis workflows, including the re-design of the production system, a new analysis data format and event model, and the development of common reduction and analysis frameworks. We r...

The analysis of the complex LHC data usually follows a standard path that aims at minimizing not only the amount of data but also the number of observables used. After a number of steps of slimming and skimming the data, the remaining few terabytes of ROOT files hold a selection of the events and a flat structure for the variables needed that can be more easily inspected and traversed in the final stages of the analysis. PROOF arises at this point as an efficient mechanism to distribute the analysis load by taking advantage of all the cores in modern CPUs through PROOF Lite, or by using PROOF Cluster or PROOF on Demand tools to build dynamic PROOF cluster on computing facilities with spare CPUs. However using PROOF at the level required for a serious analysis introduces some difficulties that may scare new adopters. We have developed the PROOF Analysis Framework (PAF) to facilitate the development of new analysis by uniformly exposing the PROOF related configurations across technologies and by taking care of ...

Full Text Available Theme The situation analysis, as a separate component of the strategic planning, involves collecting and analysing relevant types of information on the components of the marketing environment and their evolution on the one hand and also on the organization’s resources and capabilities on the other. Objectives of the Research The main purpose of the study of the analysis techniques of the internal environment is to provide insight on those aspects that are of strategic importance to the organization. Literature Review The marketing environment consists of two distinct components, the internal environment that is made from specific variables within the organization and the external environment that is made from variables external to the organization. Although analysing the external environment is essential for corporate success, it is not enough unless it is backed by a detailed analysis of the internal environment of the organization. The internal environment includes all elements that are endogenous to the organization, which are influenced to a great extent and totally controlled by it. The study of the internal environment must answer all resource related questions, solve all resource management issues and represents the first step in drawing up the marketing strategy. Research Methodology The present paper accomplished a documentary study of the main techniques used for the analysis of the internal environment. Results The special literature emphasizes that the differences in performance from one organization to another is primarily dependant not on the differences between the fields of activity, but especially on the differences between the resources and capabilities and the ways these are capitalized on. The main methods of analysing the internal environment addressed in this paper are: the analysis of the organizational resources, the performance analysis, the value chain analysis and the functional analysis.

Biosensors first appeared several decades ago to address the need for monitoring physiological parameters such as oxygen or glucose in biological fluids such as blood. More recently, a new wave of biosensors has emerged in order to provide more nuanced and granular information about the composition and function of living cells. Such biosensors exist at the confluence of technology and medicine and often strive to connect cell phenotype or function to physiological or pathophysiological processes. Our review aims to describe some of the key technological aspects of biosensors being developed for cell analysis. The technological aspects covered in our review include biorecognition elements used for biosensor construction, methods for integrating cells with biosensors, approaches to single-cell analysis, and the use of nanostructured biosensors for cell analysis. Our hope is that the spectrum of possibilities for cell analysis described in this review may pique the interest of biomedical scientists and engineers and may spur new collaborations in the area of using biosensors for cell analysis.

It is a member of the guitar family of instruments which employs four nylon or gut strings or four courses of strings. However, a statistical analysis of the pitch of this instrument has not been conducted. To analysis pitch or fundamental frequency of its main cords should be performed in an appropriate way. This study brings about its effective sound synthesis which is an important issue in the future. Approach: An efficient technique for the analysis of the fundamental frequency (F0 of the human speech had been applied to the analysis of main cords of the ukulele. The autocorrelation-based technique was used with the signal waveform to extract the optimal period or pitch for the corresponding analyzed frame in time domain. Then the corresponding fundamental frequency was calculated in the frequency domain. Results: The 21 main cords were chosen in the study. It had been seen that the existing fundamental frequency values were varied from one to three values. The value was ranging from 65.42 Hz-329.93 Hz. Conclusion: By using the analysis technique of fundamental frequency of the human speech, the output frequencies of all main cords can be extracted. It can be empirically seen that they have their unique values from each others."

The bedside measurement of continuous arterial pressure values from waveform analysis has been routinely available via indwelling arterial catheterization for >50 years. Invasive blood pressure monitoring has been utilized in critically ill patients, in both the operating room and critical care units, to facilitate rapid diagnoses of cardiovascular insufficiency and monitor response to treatments aimed at correcting abnormalities before the consequences of either hypo- or hypertension are seen. Minimally invasive techniques to estimate cardiac output (CO) have gained increased appeal. This has led to the increased interest in arterial waveform analysis to provide this important information, as it is measured continuously in many operating rooms and intensive care units. Arterial waveform analysis also allows for the calculation of many so-called derived parameters intrinsically created by this pulse pressure profile. These include estimates of left ventricular stroke volume (SV), CO, vascular resistance, and during positive-pressure breathing, SV variation, and pulse pressure variation. This article focuses on the principles of arterial waveform analysis and their determinants, components of the arterial system, and arterial pulse contour. It will also address the advantage of measuring real-time CO by the arterial waveform and the benefits to measuring SV variation. Arterial waveform analysis has gained a large interest in the overall assessment and management of the critically ill and those at a risk of hemodynamic deterioration.
Harmonic and geometric analysis
Citti, Giovanna; Pérez, Carlos; Sarti, Alessandro; Zhong, Xiao
2015-01-01
This book presents an expanded version of four series of lectures delivered by the authors at the CRM. Harmonic analysis, understood in a broad sense, has a very wide interplay with partial differential equations and in particular with the theory of quasiconformal mappings and its applications. Some areas in which real analysis has been extremely influential are PDE's and geometric analysis. Their foundations and subsequent developments made extensive use of the Calderón–Zygmund theory, especially the Lp inequalities for Calderón–Zygmund operators (Beurling transform and Riesz transform, among others) and the theory of Muckenhoupt weights. The first chapter is an application of harmonic analysis and the Heisenberg group to understanding human vision, while the second and third chapters cover some of the main topics on linear and multilinear harmonic analysis. The last serves as a comprehensive introduction to a deep result from De Giorgi, Moser and Nash on the regularity of elliptic partial differen...
Professionalizing Intelligence Analysis

Full Text Available This article examines the current state of professionalism in national security intelligence analysis in the U.S. Government. Since the introduction of major intelligence reforms directed by the Intelligence Reform and Terrorism Prevention Act (IRTPA in December, 2004, we have seen notable strides in many aspects of intelligence professionalization, including in analysis. But progress is halting, uneven, and by no means permanent. To consolidate its gains, and if it is to continue improving, the U.S. intelligence community (IC should commit itself to accomplishing a new program of further professionalization of analysis to ensure that it will develop an analytic cadre that is fully prepared to deal with the complexities of an emerging multipolar and highly dynamic world that the IC itself is forecasting. Some recent reforms in intelligence analysis can be assessed against established standards of more fully developed professions; these may well fall short of moving the IC closer to the more fully professionalized analytical capability required for producing the kind of analysis needed now by the United States.

Since the early 20th century, medical imaging has been dominated by monochrome imaging modalities such as x-ray, computed tomography, ultrasound, and magnetic resonance imaging. As a result, color information has been overlooked in medical image analysis applications. Recently, various medical imaging modalities that involve color information have been introduced. These include cervicography, dermoscopy, fundus photography, gastrointestinal endoscopy, microscopy, and wound photography. However, in comparison to monochrome images, the analysis of color images is a relatively unexplored area. The multivariate nature of color image data presents new challenges for researchers and practitioners as the numerous methods developed for monochrome images are often not directly applicable to multichannel images. The goal of this volume is to summarize the state-of-the-art in the utilization of color information in medical image analysis.

Software safety hazard analysis
Energy Technology Data Exchange (ETDEWEB)
Lawrence, J.D. [Lawrence Livermore National Lab., CA (United States)
1996-02-01
Techniques for analyzing the safety and reliability of analog-based electronic protection systems that serve to mitigate hazards in process control systems have been developed over many years, and are reasonably well understood. An example is the protection system in a nuclear power plant. The extension of these techniques to systems which include digital computers is not well developed, and there is little consensus among software engineering experts and safety experts on how to analyze such systems. One possible technique is to extend hazard analysis to include digital computer-based systems. Software is frequently overlooked during system hazard analyses, but this is unacceptable when the software is in control of a potentially hazardous operation. In such cases, hazard analysis should be extended to fully cover the software. A method for performing software hazard analysis is proposed in this paper.

This lab experiment illustrates the use of thermogravimetric analysis (TGA) to perform proximate analysis on a series of coal samples of different rank. Peat and coke are also examined. A total of four exercises are described. These are dry exercises as students interpret previously recorded scans. The weight percent moisture, volatile matter, fixed carbon, and ash content are determined for each sample and comparisons are made. Proximate analysis is performed on a coal sample from a local electric utility. From the weight percent sulfur found in the coal (determined by a separate procedure the Eschka method) and the ash content, students calculate the quantity of sulfur dioxide emissions and ash produced annually by a large coal-fired electric power plant.

This book offers a complete and streamlined treatment of the central principles of abelian harmonic analysis: Pontryagin duality, the Plancherel theorem and the Poisson summation formula, as well as their respective generalizations to non-abelian groups, including the Selberg trace formula. The principles are then applied to spectral analysis of Heisenberg manifolds and Riemann surfaces. This new edition contains a new chapter on p-adic and adelic groups, as well as a complementary section on direct and projective limits. Many of the supporting proofs have been revised and refined. The book is an excellent resource for graduate students who wish to learn and understand harmonic analysis and for researchers seeking to apply it.

Based on an honors course taught by the author at UC Berkeley, this introduction to undergraduate real analysis gives a different emphasis by stressing the importance of pictures and hard problems. Topics include: a natural construction of the real numbers, four-dimensional visualization, basic point-set topology, function spaces, multivariable calculus via differential forms (leading to a simple proof of the Brouwer Fixed Point Theorem), and a pictorial treatment of Lebesgue theory. Over 150 detailed illustrations elucidate abstract concepts and salient points in proofs. The exposition is informal and relaxed, with many helpful asides, examples, some jokes, and occasional comments from mathematicians, such as Littlewood, Dieudonné, and Osserman. This book thus succeeds in being more comprehensive, more comprehensible, and more enjoyable, than standard introductions to analysis. New to the second edition of Real Mathematical Analysis is a presentation of Lebesgue integration done almost entirely using the un...
Power electronics reliability analysis.

Smith, Mark A.; Atcitty, Stanley
2009-12-01
This report provides the DOE and industry with a general process for analyzing power electronics reliability. The analysis can help with understanding the main causes of failures, downtime, and cost and how to reduce them. One approach is to collect field maintenance data and use it directly to calculate reliability metrics related to each cause. Another approach is to model the functional structure of the equipment using a fault tree to derive system reliability from component reliability. Analysis of a fictitious device demonstrates the latter process. Optimization can use the resulting baseline model to decide how to improve reliability and/or lower costs. It is recommended that both electric utilities and equipment manufacturers make provisions to collect and share data in order to lay the groundwork for improving reliability into the future. Reliability analysis helps guide reliability improvements in hardware and software technology including condition monitoring and prognostics and health management.

The well-known Gouy-Stodola theorem states that a device produces maximum useful power when working reversibly, that is with no entropy production inside the device. This statement then leads to a method of thermodynamic optimization based on entropy production minimization. Exergy destruction (difference between exergy of fuel and exhausts) is also given by entropy production inside the device. Therefore, assessing efficiency of a device by exergy analysis is also based on the Gouy-Stodola theorem. However, assumptions that had led to the Gouy-Stodola theorem are not satisfied in several optimization scenarios, e.g. non-isothermal steady-state fuel cells, where both entropy production minimization and exergy analysis should be used with caution. We demonstrate, using non-equilibrium thermodynamics, a few cases where entropy production minimization and exergy analysis should not be applied.

The Velocity Interferometer System for Any Reflector (VISAR) is a widely used diagnostic at Sandia National Laboratories. Although the operating principles of the VISAR are well established, recently deployed systems (such as the fast push-pull and air delay VISAR) require more careful consideration, and many common assumptions about VISAR are coming into question. This report presents a comprehensive review of VISAR analysis to address these issues. Detailed treatment of several interferometer configurations is given to identify important aspects of the operation and characterization of VISAR systems. The calculation of velocity from interferometer measurements is also described. The goal is to derive the standard VISAR analysis relationships, indicate when these relationships are valid, and provide alternative methods when the standard analysis fails.

Analyzing observed or measured data is an important step in applied sciences. The recent increase in computer capacity has resulted in a revolution both in data collection and data analysis. An increasing number of scientists, researchers and students are venturing into statistical data analysis; hence the need for more guidance in this field, which was previously dominated mainly by statisticians. This handbook fills the gap in the range of textbooks on data analysis. Written in a dictionary format, it will serve as a comprehensive reference book in a rapidly growing field. However, this book is more structured than an ordinary dictionary, where each entry is a separate, self-contained entity.

The purpose of this process analysis was to analyze the Badge Offices’ current processes from a systems perspective and consider ways of pursuing objectives set forth by SEC-PS, namely increased customer flow (throughput) and reduced customer wait times. Information for the analysis was gathered for the project primarily through Badge Office Subject Matter Experts (SMEs), and in-person observation of prevailing processes. Using the information gathered, a process simulation model was constructed to represent current operations and allow assessment of potential process changes relative to factors mentioned previously. The overall purpose of the analysis was to provide SEC-PS management with information and recommendations to serve as a basis for additional focused study and areas for potential process improvements in the future.
Applied multivariate statistical analysis
Härdle, Wolfgang Karl
2015-01-01
Focusing on high-dimensional applications, this 4th edition presents the tools and concepts used in multivariate data analysis in a style that is also accessible for non-mathematicians and practitioners. It surveys the basic principles and emphasizes both exploratory and inferential statistics; a new chapter on Variable Selection (Lasso, SCAD and Elastic Net) has also been added. All chapters include practical exercises that highlight applications in different multivariate data analysis fields: in quantitative financial studies, where the joint dynamics of assets are observed; in medicine, where recorded observations of subjects in different locations form the basis for reliable diagnoses and medication; and in quantitative marketing, where consumers’ preferences are collected in order to construct models of consumer behavior. All of these examples involve high to ultra-high dimensions and represent a number of major fields in big data analysis. The fourth edition of this book on Applied Multivariate ...

Fuzzy data such as marks, scores, verbal evaluations, imprecise observations, experts' opinions and grey tone pictures, are quite common. In Fuzzy Data Analysis the authors collect their recent results providing the reader with ideas, approaches and methods for processing such data when looking for sub-structures in knowledge bases for an evaluation of functional relationship, e.g. in order to specify diagnostic or control systems. The modelling presented uses ideas from fuzzy set theory and the suggested methods solve problems usually tackled by data analysis if the data are real numbers. Fuzzy Data Analysis is self-contained and is addressed to mathematicians oriented towards applications and to practitioners in any field of application who have some background in mathematics and statistics.
Neutron signal transfer analysis
Pleinert, H; Lehmann, E
1999-01-01
A new method called neutron signal transfer analysis has been developed for quantitative determination of hydrogenous distributions from neutron radiographic measurements. The technique is based on a model which describes the detector signal obtained in the measurement as a result of the action of three different mechanisms expressed by signal transfer functions. The explicit forms of the signal transfer functions are determined by Monte Carlo computer simulations and contain only the distribution as a variable. Therefore an unknown distribution can be determined from the detector signal by recursive iteration. This technique provides a simple and efficient tool for analysis of this type while also taking into account complex effects due to the energy dependency of neutron interaction and single and multiple scattering. Therefore this method provides an efficient tool for precise quantitative analysis using neutron radiography, as for example quantitative determination of moisture distributions in porous buil...
Analysis of Autopilot Behavior
Sherry, Lance; Polson, Peter; Feay, Mike; Palmer, Everett; Null, Cynthia H. (Technical Monitor)
1998-01-01
Aviation and cognitive science researchers have identified situations in which the pilot's expectations for behavior of autopilot avionics are not matched by the actual behavior of the avionics. These "automation surprises" have been attributed to differences between the pilot's model of the behavior of the avionics and the actual behavior encoded in the avionics software. A formal technique is described for the analysis and measurement of the behavior of the cruise pitch modes of a modern Autopilot. The analysis characterizes the behavior of the Autopilot as situation-action rules. The behavior of the cruise pitch mode logic for a contemporary modern Autopilot was found to include 177 rules, including Level Change (23), Vertical Speed (16), Altitude Capture (50), and Altitude Hold (88). These rules are determined based on the values of 62 inputs. Analysis of the rule-based model also shed light on the factors cited in the literature as contributors to "automation surprises."

Full Text Available The history of behavior analysis in Brazil began with the visit of Fred S. Keller as a FulbrightScholar to the University of São Paulo in 1961. Keller introduced Skinner works to the Brazilianpsychologists. His first assistant was Carolina Martuscelli Bori, then a social psychologistinfluenced by the work of Kurt Lewin. Initially guided by Keller, Carolina Bori was the majorforce in the diffusion of Behavior Analysis in Brazil, beginning with the psychology course ofthe University of Brasília, where the first course on Experimental Analysis of Behavior beganin August of 1964. Most of behavior analysts in Brazil today were students, directly or indirectly,of Carolina Bori. Several graduate programs throughout the country offer courses in behavioranalysis.

The Solar Energy Research Institute has conducted a limited sensitivity analysis on a System for Projecting the Utilization of Renewable Resources (SPURR). The study utilized the Domestic Policy Review scenario for SPURR agricultural and industrial process heat and utility market sectors. This sensitivity analysis determines whether variations in solar system capital cost, operation and maintenance cost, and fuel cost (biomass only) correlate with intuitive expectations. The results of this effort contribute to a much larger issue: validation of SPURR. Such a study has practical applications for engineering improvements in solar technologies and is useful as a planning tool in the R and D allocation process.

Small space flight project design at NASA Langley Research Center goes through a multi-phase process from preliminary analysis to flight operations. The process insures that each system achieves its technical objectives with demonstrated quality and within planned budgets and schedules. A key technical component of early phases is decision analysis, which is a structure procedure for determining the best of a number of feasible concepts based upon project objectives. Feasible system concepts are generated by the designers and analyzed for schedule, cost, risk, and technical measures. Each performance measure value is normalized between the best and worst values and a weighted average score of all measures is calculated for each concept. The concept(s) with the highest scores are retained, while others are eliminated from further analysis. This project automated and enhanced the decision analysis process. Automation of the decision analysis process was done by creating a user-friendly, menu-driven, spreadsheet macro based decision analysis software program. The program contains data entry dialog boxes, automated data and output report generation, and automated output chart generation. The enhancements to the decision analysis process permit stochastic data entry and analysis. Rather than enter single measure values, the designers enter the range and most likely value for each measure and concept. The data can be entered at the system or subsystem level. System level data can be calculated as either sum, maximum, or product functions of the subsystem data. For each concept, the probability distributions are approximated for each measure and the total score for each concept as either constant, triangular, normal, or log-normal distributions. Based on these distributions, formulas are derived for the probability that the concept meets any given constraint, the probability that the concept meets all constraints, and the probability that the concept is within a given

In the late 1950s, many of the more refined aspects of Fourier analysis were transferred from their original settings (the unit circle, the integers, the real line) to arbitrary locally compact abelian (LCA) groups. Rudin's book, published in 1962, was the first to give a systematic account of these developments and has come to be regarded as a classic in the field. The basic facts concerning Fourier analysis and the structure of LCA groups are proved in the opening chapters, in order to make the treatment relatively self-contained.

A new unsupervised feature extraction method called similar component analysis (SCA) is proposed in this paper. SCA method has a self-aggregation property that the data objects will move towards each other to form clusters through SCA theoretically,which can reveal the inherent pattern of similarity hidden in the dataset. The inputs of SCA are just the pairwise similarities of the dataset,which makes it easier for time series analysis due to the variable length of the time series. Our experimental results on many problems have verified the effectiveness of SCA on some engineering application.

Monotowns: A Quantitative Analysis

Shastitko Andrei
2016-06-01
Full Text Available The authors propose an empirical analysis of the current situation in monotowns. The study questions the perceived seriousness of the ‘monotown problem’ as well as the actual challenges it presents. The authors use a cluster analysis to divide monotowns into groups for further structural comparison. The structural differences in the available databases limit the possibilities of empirical analysis. Hence, alternative approaches are required. The authors consider possible reasons for the limitations identified. Special attention is paid to the monotowns that were granted the status of advanced development territories. A comparative analysis makes it possible to study their general characteristics and socioeconomic indicators. The authors apply the theory of opportunistic behaviour to describe potential problems caused by the lack of unified criteria for granting monotowns the status of advanced development territories. The article identifies the main stakeholders and the character of their interaction; it desc ribes a conceptual model built on the principal/agent interactions, and identifies the parametric space of mutually beneficial cooperation. The solution to the principal/agent problem suggested in the article contributes to the development of an alternative approach to the current situation and a rational approach to overcoming the ‘monotown problem’.

This is a textbook on proof writing in the area of analysis, balancing a survey of the core concepts of mathematical proof with a tight, rigorous examination of the specific tools needed for an understanding of analysis. Instead of the standard "transition" approach to teaching proofs, wherein students are taught fundamentals of logic, given some common proof strategies such as mathematical induction, and presented with a series of well-written proofs to mimic, this textbook teaches what a student needs to be thinking about when trying to construct a proof. Covering the fundamentals of analysis sufficient for a typical beginning Real Analysis course, it never loses sight of the fact that its primary focus is about proof writing skills. This book aims to give the student precise training in the writing of proofs by explaining exactly what elements make up a correct proof, how one goes about constructing an acceptable proof, and, by learning to recognize a correct proof, how to avoid writing incorrect proofs.

To impart hands-on training in physics analysis, CMS experiment initiated the concept of CMS Data Analysis School (CMSDAS). It was born over three years ago at the LPC (LHC Physics Centre), Fermilab and is based on earlier workshops held at the LPC and CLEO Experiment. As CMS transitioned from construction to the data taking mode, the nature of earlier training also evolved to include more of analysis tools, software tutorials and physics analysis. This effort epitomized as CMSDAS has proven to be a key for the new and young physicists to jump start and contribute to the physics goals of CMS by looking for new physics with the collision data. With over 400 physicists trained in six CMSDAS around the globe, CMS is trying to engage the collaboration in its discovery potential and maximize physics output. As a bigger goal, CMS is striving to nurture and increase engagement of the myriad talents, in the development of physics, service, upgrade, education of those new to CMS and the career development of younger members. An extension of the concept to the dedicated software and hardware schools is also planned, keeping in mind the ensuing upgrade phase.

With increasing accessibility to geographic information systems (GIS) software, statisticians and data analysts routinely encounter scientific data sets with geocoded locations. This has generated considerable interest in statistical modeling for location-referenced spatial data. In public health, spatial data routinely arise as aggregates over regions, such as counts or rates over counties, census tracts, or some other administrative delineation. Such data are often referred to as areal data. This review article provides a brief overview of statistical models that account for spatial dependence in areal data. It does so in the context of two applications: disease mapping and spatial survival analysis. Disease maps are used to highlight geographic areas with high and low prevalence, incidence, or mortality rates of a specific disease and the variability of such rates over a spatial domain. They can also be used to detect hot spots or spatial clusters that may arise owing to common environmental, demographic, or cultural effects shared by neighboring regions. Spatial survival analysis refers to the modeling and analysis for geographically referenced time-to-event data, where a subject is followed up to an event (e.g., death or onset of a disease) or is censored, whichever comes first. Spatial survival analysis is used to analyze clustered survival data when the clustering arises from geographical regions or strata. Illustrations are provided in these application domains.
ATLAS Distributed Analysis Tools
Gonzalez de la Hoz, Santiago; Liko, Dietrich
2008-01-01
The ATLAS production system has been successfully used to run production of simulation data at an unprecedented scale. Up to 10000 jobs were processed in one day. The experiences obtained operating the system on several grid flavours was essential to perform a user analysis using grid resources. First tests of the distributed analysis system were then performed. In the preparation phase data was registered in the LHC File Catalog (LFC) and replicated in external sites. For the main test, few resources were used. All these tests are only a first step towards the validation of the computing model. The ATLAS management computing board decided to integrate the collaboration efforts in distributed analysis in only one project, GANGA. The goal is to test the reconstruction and analysis software in a large scale Data production using Grid flavors in several sites. GANGA allows trivial switching between running test jobs on a local batch system and running large-scale analyses on the Grid; it provides job splitting a...

As the launch of LISA Pathfinder (LPF) draws near, more and more effort is being put in to the preparation of the data analysis activities that will be carried out during the mission operations. The operations phase of the mission will be composed of a series of experiments that will be carried out on the satellite. These experiments will be directed and analysed by the data analysis team, which is part of the operations team. The operations phase will last about 90 days, during which time the data analysis team aims to fully characterize the LPF, and in particular, its core instrument the LISA Technology Package. By analysing the various couplings present in the system, the different noise sources that will disturb the system, and through the identification of the key physical parameters of the system, a detailed noise budget of the instrument will be constructed that will allow the performance of the different subsystems to be assessed and projected towards LISA. This paper describes the various aspects of the full data analysis chain that are needed to successfully characterize the LPF and build up the noise budget during mission operations.

The improvement of safety in nuclear power stations is an important proposition. Therefore also as to the safety evaluation, it is important to comprehensively and systematically execute it by referring to the operational experience and the new knowledge which is important for the safety throughout the period of use as well as before the construction and the start of operation of nuclear power stations. In this report, the results when the safety analysis for ``Fugen`` was carried out by referring to the newest technical knowledge are described. As the result, it was able to be confirmed that the safety of ``Fugen`` has been secured by the inherent safety and the facilities which were designed for securing the safety. The basic way of thinking on the safety analysis including the guidelines to be conformed to is mentioned. As to the abnormal transient change in operation and accidents, their definition, the events to be evaluated and the standards for judgement are reported. The matters which were taken in consideration at the time of the analysis are shown. The computation programs used for the analysis were REACT, HEATUP, LAYMON, FATRAC, SENHOR, LOTRAC, FLOOD and CONPOL. The analyses of the abnormal transient change in operation and accidents are reported on the causes, countermeasures, protective functions and results. (K.I.)

Investigations in food science and technology, whether by the food industry, governmental agencies, or universities, often require determination of food composition and characteristics. Trends and demands of consumers, the food industry, and national and international regulations challenge food scientists as they work to monitor food composition and to ensure the quality and safety of the food supply. All food products require analysis as part of a quality management program throughout the development process (including raw ingredients), through production, and after a product is in the market. In addition, analysis is done of problem samples and competitor products. The characteristics of foods (i.e., chemical composition, physical properties, sensory properties) are used to answer specific questions for regulatory purposes and typical quality control. The nature of the sample and the specific reason for the analysis commonly dictate the choice of analytical methods. Speed, precision, accuracy, and ruggedness often are key factors in this choice. Validation of the method for the specific food matrix being analyzed is necessary to ensure usefulness of the method. Making an appropriate choice of the analytical technique for a specific application requires a good knowledge of the various techniques (Fig. 1.1). For example, your choice of method to determine the salt content of potato chips would be different if it is for nutrition labeling than for quality control. The success of any analytical method relies on the proper selection and preparation of the food sample, carefully performing the analysis, and doing the appropriate calculations and interpretation of the data. Methods of analysis developed and endorsed by several nonprofit scientific organizations allow for standardized comparisons of results between different laboratories and for evaluation of less standard procedures. Such official methods are critical in the analysis of foods, to ensure that they meet

The Hydrogen Program of the U.S. Department of Energy (DOE) funds a portfolio of activities ranging from conceptual research to pilot plant testing. The long-term research projects support DOE`s goal of a sustainable, domestically based energy system, and the development activities are focused on hydrogen-based energy systems that can be commercially viable in the near-term. Energetics develops analytic products that enable the Hydrogen Program Manager to assess the potential for near- and long-term R&D activities to satisfy DOE and energy market criteria. This work is based on a pathway analysis methodology. The authors consider an energy component (e.g., hydrogen production from biomass gasification, hybrid hydrogen internal combustion engine (ICE) vehicle) within a complete energy system. The work involves close interaction with the principal investigators to ensure accurate representation of the component technology. Comparisons are made with the current cost and performance of fossil-based and alternative renewable energy systems, and sensitivity analyses are conducted to determine the effect of changes in cost and performance parameters on the projects` viability.
Extended Testability Analysis Tool
Melcher, Kevin; Maul, William A.; Fulton, Christopher
2012-01-01
The Extended Testability Analysis (ETA) Tool is a software application that supports fault management (FM) by performing testability analyses on the fault propagation model of a given system. Fault management includes the prevention of faults through robust design margins and quality assurance methods, or the mitigation of system failures. Fault management requires an understanding of the system design and operation, potential failure mechanisms within the system, and the propagation of those potential failures through the system. The purpose of the ETA Tool software is to process the testability analysis results from a commercial software program called TEAMS Designer in order to provide a detailed set of diagnostic assessment reports. The ETA Tool is a command-line process with several user-selectable report output options. The ETA Tool also extends the COTS testability analysis and enables variation studies with sensor sensitivity impacts on system diagnostics and component isolation using a single testability output. The ETA Tool can also provide extended analyses from a single set of testability output files. The following analysis reports are available to the user: (1) the Detectability Report provides a breakdown of how each tested failure mode was detected, (2) the Test Utilization Report identifies all the failure modes that each test detects, (3) the Failure Mode Isolation Report demonstrates the system s ability to discriminate between failure modes, (4) the Component Isolation Report demonstrates the system s ability to discriminate between failure modes relative to the components containing the failure modes, (5) the Sensor Sensor Sensitivity Analysis Report shows the diagnostic impact due to loss of sensor information, and (6) the Effect Mapping Report identifies failure modes that result in specified system-level effects.
Ceramic tubesheet design analysis

Mallett, R.H.; Swindeman, R.W.
1996-06-01
A transport combustor is being commissioned at the Southern Services facility in Wilsonville, Alabama to provide a gaseous product for the assessment of hot-gas filtering systems. One of the barrier filters incorporates a ceramic tubesheet to support candle filters. The ceramic tubesheet, designed and manufactured by Industrial Filter and Pump Manufacturing Company (EF&PM), is unique and offers distinct advantages over metallic systems in terms of density, resistance to corrosion, and resistance to creep at operating temperatures above 815{degrees}C (1500{degrees}F). Nevertheless, the operational requirements of the ceramic tubesheet are severe. The tubesheet is almost 1.5 m in (55 in.) in diameter, has many penetrations, and must support the weight of the ceramic filters, coal ash accumulation, and a pressure drop (one atmosphere). Further, thermal stresses related to steady state and transient conditions will occur. To gain a better understanding of the structural performance limitations, a contract was placed with Mallett Technology, Inc. to perform a thermal and structural analysis of the tubesheet design. The design analysis specification and a preliminary design analysis were completed in the early part of 1995. The analyses indicated that modifications to the design were necessary to reduce thermal stress, and it was necessary to complete the redesign before the final thermal/mechanical analysis could be undertaken. The preliminary analysis identified the need to confirm that the physical and mechanical properties data used in the design were representative of the material in the tubesheet. Subsequently, few exploratory tests were performed at ORNL to evaluate the ceramic structural material.

We introduce a new methodology for inferring the accuracy of computational simulations through the practice of solution verification. We demonstrate this methodology on examples from computational heat transfer, fluid dynamics and radiation transport. Our methodology is suited to both well- and ill-behaved sequences of simulations. Our approach to the analysis of these sequences of simulations incorporates expert judgment into the process directly via a flexible optimization framework, and the application of robust statistics. The expert judgment is systematically applied as constraints to the analysis, and together with the robust statistics guards against over-emphasis on anomalous analysis results. We have named our methodology Robust Verification. Our methodology is based on utilizing multiple constrained optimization problems to solve the verification model in a manner that varies the analysis' underlying assumptions. Constraints applied in the analysis can include expert judgment regarding convergence rates (bounds and expectations) as well as bounding values for physical quantities (e.g., positivity of energy or density). This approach then produces a number of error models, which are then analyzed through robust statistical techniques (median instead of mean statistics). This provides self-contained, data and expert informed error estimation including uncertainties for both the solution itself and order of convergence. Our method produces high quality results for the well-behaved cases relatively consistent with existing practice. The methodology can also produce reliable results for ill-behaved circumstances predicated on appropriate expert judgment. We demonstrate the method and compare the results with standard approaches used for both code and solution verification on well-behaved and ill-behaved simulations.

We provide analysis of Oracle StorageTek T10000 Generation B (T10KB) Media Information Record (MIR) Performance Data gathered over the course of a year from our production High Performance Storage System (HPSS). The analysis shows information in the MIR may be used to improve tape subsystem operations. Most notably, we found the MIR information to be helpful in determining whether the drive or tape was most suspect given a read or write error, and for helping identify which tapes should not be reused given their history of read or write errors. We also explored using the MIR Assisted Search to order file retrieval requests. We found that MIR Assisted Search may be used to reduce the time needed to retrieve collections of files from a tape volume.
Communication Analysis modelling techniques
España, Sergio; Pastor, Óscar; Ruiz, Marcela
2012-01-01
This report describes and illustrates several modelling techniques proposed by Communication Analysis; namely Communicative Event Diagram, Message Structures and Event Specification Templates. The Communicative Event Diagram is a business process modelling technique that adopts a communicational perspective by focusing on communicative interactions when describing the organizational work practice, instead of focusing on physical activities1; at this abstraction level, we refer to business activities as communicative events. Message Structures is a technique based on structured text that allows specifying the messages associated to communicative events. Event Specification Templates are a means to organise the requirements concerning a communicative event. This report can be useful to analysts and business process modellers in general, since, according to our industrial experience, it is possible to apply many Communication Analysis concepts, guidelines and criteria to other business process modelling notation...

Traditionaly, the primary role of supercomputers was to create data, primarily for simulation applications. Due to usage and technology trends, supercomputers are increasingly also used for data analysis. Some of this data is from simulations, but there is also a rapidly increasingly amount of real-world science and business data to be analyzed. We briefly overview Blue Gene and other current supercomputer architectures. We outline future architectures, up to the Exascale supercomputers expected in the 2020 time frame. We focus on the data analysis challenges and opportunites, especially those concerning Flash and other up-and-coming storage class memory. About the speakers Blake G. Fitch has been with IBM Research, Yorktown Heights, NY since 1987, mainly pursuing interests in parallel systems.

In Silico Expression Analysis.
Bolívar, Julio; Hehl, Reinhard; Bülow, Lorenz

Information on the specificity of cis-sequences enables the design of functional synthetic plant promoters that are responsive to specific stresses. Potential cis-sequences may be experimentally tested, however, correlation of genomic sequence with gene expression data enables an in silico expression analysis approach to bioinformatically assess the stress specificity of candidate cis-sequences prior to experimental verification. The present chapter demonstrates an example for the in silico validation of a potential cis-regulatory sequence responsive to cold stress. The described online tool can be applied for the bioinformatic assessment of cis-sequences responsive to most abiotic and biotic stresses of plants. Furthermore, a method is presented based on a reverted in silico expression analysis approach that predicts highly specific potentially functional cis-regulatory elements for a given stress.

Many common management techniques have little use in managing a medical group practice. Ratio analysis, however, can easily be adapted to the group practice setting. Acting as broad-gauge indicators, financial ratios provide an early warning of potential problems and can be very useful in planning for future operations. The author has gathered a collection of financial ratios which were developed by participants at an education seminar presented for the Virginia Medical Group Management Association. Classified according to the human element, system component, and financial factor, the ratios provide a good sampling of measurements relevant to medical group practices and can serve as an example for custom-tailoring a ratio analysis system for your medical group.

Jumper connectors are used for remotely connecting pipe lines containing transfer fluids ranging from hazardous chemicals to other nonhazardous liquids. The jumper connector assembly comprises hooks, hookpins, a block, a nozzle, an operating screw, and a nut. The hooks are tightened against the nozzle flanges by the operating screw that is tightened with a remotely connected torque wrench. Stress analysis for the jumper connector assembly (used extensively on the US Department of Energy's Hanford Site, near Richland, Washington) is performed by using hand calculation and finite-element techniques to determine the stress levels resulting from operating and seismic loads on components of the assembly. The analysis addresses loading conditions such as prestress, seismic, operating, thermal, and leakage. The preload torque-generated forces at which each component reaches its stress limits are presented in a tabulated format. Allowable operating loads for the jumper assembly are provided to prevent leakage of the assembly during operating cycles.

2015-02-01
This article focuses on analytical strategies integrating atomic spectroscopy in biotechnology. The rationale behind developing such methods is inherently linked to unique features of the key technique in elemental analysis, which is inductively coupled plasma mass spectrometry: (1) the high sensitivity and selectivity of state of the art instrumentation, (2) the possibility of accurate absolute quantification even in complex matrices, (3) the capability of combining elemental detectors with chromatographic separation methods and the versatility of the latter approach, (4) the complementarity of inorganic and organic mass spectrometry, (5) the multi-element capability and finally (6) the capability of isotopic analysis. The article highlights the most recent bio-analytical developments exploiting these methodological advantages and shows the potential in biotechnological applications.
Exploration Laboratory Analysis - ARC
Krihak, Michael K.; Fung, Paul P.
2012-01-01
The Exploration Laboratory Analysis (ELA) project supports the Exploration Medical Capability (ExMC) risk, Risk of Inability to Adequately Treat an Ill or Injured Crew Member, and ExMC Gap 4.05: Lack of minimally invasive in-flight laboratory capabilities with limited consumables required for diagnosing identified Exploration Medical Conditions. To mitigate this risk, the availability of inflight laboratory analysis instrumentation has been identified as an essential capability in future exploration missions. Mission architecture poses constraints on equipment and procedures that will be available to treat evidence-based medical conditions according to the Space Medicine Exploration Medical Conditions List (SMEMCL). The SMEMCL provided diagnosis and treatment for the evidence-based medical conditions and hence, a basis for developing ELA functional requirements.
Invitation to complex analysis
Boas, Ralph P
2010-01-01
Ideal for a first course in complex analysis, this book can be used either as a classroom text or for independent study. Written at a level accessible to advanced undergraduates and beginning graduate students, the book is suitable for readers acquainted with advanced calculus or introductory real analysis. The treatment goes beyond the standard material of power series, Cauchy's theorem, residues, conformal mapping, and harmonic functions by including accessible discussions of intriguing topics that are uncommon in a book at this level. The flexibility afforded by the supplementary topics and applications makes the book adaptable either to a short, one-term course or to a comprehensive, full-year course. Detailed solutions of the exercises both serve as models for students and facilitate independent study. Supplementary exercises, not solved in the book, provide an additional teaching tool. This second edition has been painstakingly revised by the author's son, himself an award-winning mathematical expositor...

There are children who are assumed to have normal hearing and normal intelligence, but who do not speak at all. The phoniatric diagnosis for these children used to be audimutitas. Nowadays these children are not specified any more. They are called language-disturbed and are diagnosed and treated like all other language-disturbed children. An analysis is made of 46 nonspeaking children, aged 1.5-3, who are assumed to understand language in a proper way. The analysis deals with their language (language comprehension, language production and pragmatics) as well as with medical and psychological factors influencing the language disorder. We found no correlations between language comprehension, language production and pragmatics. So, when we know one language aspect, we cannot be sure of the others. We also found various factors contributing to the language problem.
Nonstandard asymptotic analysis
Berg, Imme
1987-01-01
This research monograph considers the subject of asymptotics from a nonstandard view point. It is intended both for classical asymptoticists - they will discover a new approach to problems very familiar to them - and for nonstandard analysts but includes topics of general interest, like the remarkable behaviour of Taylor polynomials of elementary functions. Noting that within nonstandard analysis, "small", "large", and "domain of validity of asymptotic behaviour" have a precise meaning, a nonstandard alternative to classical asymptotics is developed. Special emphasis is given to applications in numerical approximation by convergent and divergent expansions: in the latter case a clear asymptotic answer is given to the problem of optimal approximation, which is valid for a large class of functions including many special functions. The author's approach is didactical. The book opens with a large introductory chapter which can be read without much knowledge of nonstandard analysis. Here the main features of the t...

What is this sound? What does that sound indicate? These are two questions frequently heard in daily conversation. Sound results from the vibrations of elastic media and in daily life provides informative signals of events happening in the surrounding environment. In interpreting auditory sensations, the human ear seems particularly good at extracting the signal signatures from sound waves. Although exploring auditory processing schemes may be beyond our capabilities, source signature analysis is a very attractive area in which signal-processing schemes can be developed using mathematical expressions. This book is inspired by such processing schemes and is oriented to signature analysis of waveforms. Most of the examples in the book are taken from data of sound and vibrations; however, the methods and theories are mostly formulated using mathematical expressions rather than by acoustical interpretation. This book might therefore be attractive and informative for scientists, engineers, researchers, and graduat...

Reconstructability analysis of epistasis.
Zwick, Martin
2011-01-01
The literature on epistasis describes various methods to detect epistatic interactions and to classify different types of epistasis. Reconstructability analysis (RA) has recently been used to detect epistasis in genomic data. This paper shows that RA offers a classification of types of epistasis at three levels of resolution (variable-based models without loops, variable-based models with loops, state-based models). These types can be defined by the simplest RA structures that model the data without information loss; a more detailed classification can be defined by the information content of multiple candidate structures. The RA classification can be augmented with structures from related graphical modeling approaches. RA can analyze epistatic interactions involving an arbitrary number of genes or SNPs and constitutes a flexible and effective methodology for genomic analysis.

Continual improvements in data collection and processing have had a huge impact on brain research, producing data sets that are often large and complicated. By emphasizing a few fundamental principles, and a handful of ubiquitous techniques, Analysis of Neural Data provides a unified treatment of analytical methods that have become essential for contemporary researchers. Throughout the book ideas are illustrated with more than 100 examples drawn from the literature, ranging from electrophysiology, to neuroimaging, to behavior. By demonstrating the commonality among various statistical approaches the authors provide the crucial tools for gaining knowledge from diverse types of data. Aimed at experimentalists with only high-school level mathematics, as well as computationally-oriented neuroscientists who have limited familiarity with statistics, Analysis of Neural Data serves as both a self-contained introduction and a reference work.

Dental Forensics: Bitemark Analysis
Directory of Open Access Journals (Sweden)
Elza Ibrahim Auerkari
2013-06-01
Full Text Available Forensic odontology (dental forensics can provide useful evidence in both criminal and civil cases, and therefore remains a part of the wider discipline of forensic science. As an example from the toolbox of forensic odontology, the practice and experience on bitemark analysis is reviewed here in brief. The principle of using visible bitemarks in crime victims or in other objects as evidence is fundamentally based on the observation that the detailed pattern of dental imprints tend to be practically unique for each individual. Therefore, finding such an imprint as a bitemark can bear a strong testimony that it was produced by the individual that has the matching dental pattern. However, the comparison of the observed bitemark and the suspected set of teeth will necessarily require human interpretation, and this is not infallible. Both technical challenges in the bitemarks and human errors in the interpretation are possible. To minimise such errors and to maximise the value of bitemark analysis, dedicated procedures and protocols have been developed, and the personnel taking care of the analysis need to be properly trained. In principle the action within the discipline should be conducted as in evidence-based dentristy, i.e. accepted procedures should have known error rates. Because of the involvement of human interpretation, even personal performance statistics may be required from legal expert statements. The requirements have been introduced largely due to cases where false convictions based on bitemark analysishave been overturned after DNA analysis.DOI: 10.14693/jdi.v15i2.76

CLEAN: CLustering Enrichment ANalysis
Directory of Open Access Journals (Sweden)
Medvedovic Mario
2009-07-01
Full Text Available Abstract Background Integration of biological knowledge encoded in various lists of functionally related genes has become one of the most important aspects of analyzing genome-wide functional genomics data. In the context of cluster analysis, functional coherence of clusters established through such analyses have been used to identify biologically meaningful clusters, compare clustering algorithms and identify biological pathways associated with the biological process under investigation. Results We developed a computational framework for analytically and visually integrating knowledge-based functional categories with the cluster analysis of genomics data. The framework is based on the simple, conceptually appealing, and biologically interpretable gene-specific functional coherence score (CLEAN score. The score is derived by correlating the clustering structure as a whole with functional categories of interest. We directly demonstrate that integrating biological knowledge in this way improves the reproducibility of conclusions derived from cluster analysis. The CLEAN score differentiates between the levels of functional coherence for genes within the same cluster based on their membership in enriched functional categories. We show that this aspect results in higher reproducibility across independent datasets and produces more informative genes for distinguishing different sample types than the scores based on the traditional cluster-wide analysis. We also demonstrate the utility of the CLEAN framework in comparing clusterings produced by different algorithms. CLEAN was implemented as an add-on R package and can be downloaded at http://Clusteranalysis.org. The package integrates routines for calculating gene specific functional coherence scores and the open source interactive Java-based viewer Functional TreeView (FTreeView. Conclusion Our results indicate that using the gene-specific functional coherence score improves the reproducibility of the

Paternity analysis using microsatellite information is a well-studied subject. These markers are ideal for parentage studies and fingerprinting, due to their high-discrimination power. This type of data is used to assign paternity, to compute the average selfing and outcrossing rates and to estimate the biparental inbreeding. There are several public domain programs that compute all this information from data. Most of the time, it is necessary to export data to some sort of format, feed it to the program and import the output to an Excel book for further processing. In this article we briefly describe a program referred from now on as Paternity Analysis in Excel (PAE), developed at IST and IBET (see the acknowledgments) that computes paternity candidates from data, and other information, from within Excel. In practice this means that the end user provides the data in an Excel sheet and, by pressing an appropriate button, obtains the results in another Excel sheet. For convenience PAE is divided into two modules. The first one is a filtering module that selects data from the sequencer and reorganizes it in a format appropriate to process paternity analysis, assuming certain conventions for the names of parents and offspring from the sequencer. The second module carries out the paternity analysis assuming that one parent is known. Both modules are written in Excel-VBA and can be obtained at the address (www.math.ist.utl.pt/~fmd/pa/pa.zip). They are free for non-commercial purposes and have been tested with different data and against different software (Cervus, FaMoz, and MLTR).

Scholars currently use various definitions for mindfulness. While some of these definitions overlap, significant differences remain and a general scholarly consensus has yet to be reached. Several domestic and international studies have explored mindfulness-related interventions and their effectiveness. However, the majority of these studies have focused on the fields of clinical medicine, consultation, and education. Mindfulness has rarely been applied in clinical nursing practice and no related systematic concept analysis has been conducted. This paper conducts a concept analysis of mindfulness using the concept analysis method proposed by Walker and Avant (2011). We describe the defining characteristics of mindfulness, clarify the concept, and confirm the predisposing factors and effects of mindfulness using examples of typical cases, borderline cases, related cases, and contrary case. Findings may provide nursing staff with an understanding of the concept of mindfulness for use in clinical practice in order to help patients achieve a comfortable state of body and mind healing.

The fallout from a nuclear explosion has the potential to injure or kill 100,000 or more people through exposure to external gamma (fallout) radiation. Existing buildings can reduce radiation exposure by placing material between fallout particles and exposed people. Lawrence Livermore National Laboratory was tasked with developing an operationally feasible methodology that could improve fallout casualty estimates. The methodology, called a Regional Shelter Analysis, combines the fallout protection that existing buildings provide civilian populations with the distribution of people in various locations. The Regional Shelter Analysis method allows the consideration of (a) multiple building types and locations within buildings, (b) country specific estimates, (c) population posture (e.g., unwarned vs. minimally warned), and (d) the time of day (e.g., night vs. day). The protection estimates can be combined with fallout predictions (or measurements) to (a) provide a more accurate assessment of exposure and injury and (b) evaluate the effectiveness of various casualty mitigation strategies. This report describes the Regional Shelter Analysis methodology, highlights key operational aspects (including demonstrating that the methodology is compatible with current tools), illustrates how to implement the methodology, and provides suggestions for future work.

Medical Image Analysis Facility
1978-01-01
To improve the quality of photos sent to Earth by unmanned spacecraft. NASA's Jet Propulsion Laboratory (JPL) developed a computerized image enhancement process that brings out detail not visible in the basic photo. JPL is now applying this technology to biomedical research in its Medical lrnage Analysis Facility, which employs computer enhancement techniques to analyze x-ray films of internal organs, such as the heart and lung. A major objective is study of the effects of I stress on persons with heart disease. In animal tests, computerized image processing is being used to study coronary artery lesions and the degree to which they reduce arterial blood flow when stress is applied. The photos illustrate the enhancement process. The upper picture is an x-ray photo in which the artery (dotted line) is barely discernible; in the post-enhancement photo at right, the whole artery and the lesions along its wall are clearly visible. The Medical lrnage Analysis Facility offers a faster means of studying the effects of complex coronary lesions in humans, and the research now being conducted on animals is expected to have important application to diagnosis and treatment of human coronary disease. Other uses of the facility's image processing capability include analysis of muscle biopsy and pap smear specimens, and study of the microscopic structure of fibroprotein in the human lung. Working with JPL on experiments are NASA's Ames Research Center, the University of Southern California School of Medicine, and Rancho Los Amigos Hospital, Downey, California.

The major thrust of this book is to present a technique of analysis that aids the formulation, understanding, and solution of problems of viscous flow. The intent is to avoid providing a "canned" program to solve a problem, offering instead a way to recognize the underlying physical, mathematical, and modeling concepts inherent in the solutions. The reader must first choose a mathematical model and derive governing equations based on realistic assumptions, or become aware of the limitations and assumptions associated with existing models. An appropriate solution technique is then selected. The solution technique may be either analytical or numerical. Computer-aided analysis algorithms supplement the classical analyses. The book begins by deriving the Navier-Stokes equation for a viscous compressible variable property fluid. The second chapter considers exact solutions of the incompressible hydrodynamic boundary layer equations solved with and without mass transfer at the wall. Forced convection, free convection, and the compressible laminar boundary layer are discussed in the remaining chapters. The text unifies the various topics by tracing a logical progression from simple to complex governing differential equations and boundary conditions. Numerical, parametric, and directed analysis problems are included at the end of each chapter.
Interstage Flammability Analysis Approach
Little, Jeffrey K.; Eppard, William M.
2011-01-01
The Interstage of the Ares I launch platform houses several key components which are on standby during First Stage operation: the Reaction Control System (ReCS), the Upper Stage (US) Thrust Vector Control (TVC) and the J-2X with the Main Propulsion System (MPS) propellant feed system. Therefore potentially dangerous leaks of propellants could develop. The Interstage leaks analysis addresses the concerns of localized mixing of hydrogen and oxygen gases to produce deflagration zones in the Interstage of the Ares I launch vehicle during First Stage operation. This report details the approach taken to accomplish the analysis. Specified leakage profiles and actual flammability results are not presented due to proprietary and security restrictions. The interior volume formed by the Interstage walls, bounding interfaces with the Upper and First Stages, and surrounding the J2-X engine was modeled using Loci-CHEM to assess the potential for flammable gas mixtures to develop during First Stage operations. The transient analysis included a derived flammability indicator based on mixture ratios to maintain achievable simulation times. Validation of results was based on a comparison to Interstage pressure profiles outlined in prior NASA studies. The approach proved useful in the bounding of flammability risk in supporting program hazard reviews.

This guide applies to the estimation of uncertainty in quantities calculated by scientific, analysis and design computer programs that fall within the scope of AECL's software quality assurance (SQA) manual. The guide weaves together rational approaches from the SQA manual and three other diverse sources: (a) the CSAU (Code Scaling, Applicability, and Uncertainty) evaluation methodology; (b) the ISO Guide,for the Expression of Uncertainty in Measurement; and (c) the SVA (Systems Variability Analysis) method of risk analysis. This report describes the manner by which random and systematic uncertainties in calculated quantities can be estimated and expressed. Random uncertainty in model output can be attributed to uncertainties of inputs. The propagation of these uncertainties through a computer model can be represented in a variety of ways, including exact calculations, series approximations and Monte Carlo methods. Systematic uncertainties emerge from the development of the computer model itself, through simplifications and conservatisms, for example. These must be estimated and combined with random uncertainties to determine the combined uncertainty in a model output. This report also addresses the method by which uncertainties should be employed in code validation, in order to determine whether experiments and simulations agree, and whether or not a code satisfies the required tolerance for its application.

This Analysis/Model Report (AMR) documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain (YM), Nevada (Figure l), the site of a potential repository for high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this AMR provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the infiltration model (USGS 2000) and for the total system performance assessment for the Site Recommendation (TSPA-SR) at YM. Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one method, among many, of establishing upper and lower bounds for future climate estimates. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. Other studies might develop a different rationale or select other past climates resulting in a different future climate analog.
Nominal analysis of "variance".
Weiss, David J
2009-08-01
Nominal responses are the natural way for people to report actions or opinions. Because nominal responses do not generate numerical data, they have been underutilized in behavioral research. On those occasions in which nominal responses are elicited, the responses are customarily aggregated over people or trials so that large-sample statistics can be employed. A new analysis is proposed that directly associates differences among responses with particular sources in factorial designs. A pair of nominal responses either matches or does not; when responses do not match, they vary. That analogue to variance is incorporated in the nominal analysis of "variance" (NANOVA) procedure, wherein the proportions of matches associated with sources play the same role as do sums of squares in an ANOVA. The NANOVA table is structured like an ANOVA table. The significance levels of the N ratios formed by comparing proportions are determined by resampling. Fictitious behavioral examples featuring independent groups and repeated measures designs are presented. A Windows program for the analysis is available.

Simplified seismic risk analysis

Within the context of probabilistic safety analysis (PSA) for nuclear power plants (NPP's), seismic risk assessment has the purpose to demonstrate that the contribution of seismic events to overall risk is not excessive. The most suitable vehicle for seismic risk assessment is a full scope seismic PSA (SPSA), in which the frequency of core damage due to seismic events is estimated. An alternative method is represented by seismic margin assessment (SMA), which aims at showing sufficient margin between the site-specific safe shutdown earthquake (SSE) and the actual capacity of the plant. Both methods are based on system analysis (fault-trees and event-trees) and hence require fragility estimates for safety relevant systems, structures and components (SSC's). If the seismic conditions at a specific site of a plant are not very demanding, then it is reasonable to expect that the risk due to seismic events is low. In such cases, the cost-benefit ratio for performing a full scale, site-specific SPSA or SMA will be excessive, considering the ultimate objective of seismic risk analysis. Rather, it will be more rational to rely on a less comprehensive analysis, used as a basis for demonstrating that the risk due to seismic events is not excessive. The present paper addresses such a simplified approach to seismic risk assessment which is used in AREVA to: - estimate seismic risk in early design stages, - identify needs to extend the design basis, - define a reasonable level of seismic risk analysis Starting from a conservative estimate of the overall plant capacity, in terms of the HCLPF (High Confidence of Low Probability of Failure), and utilizing a generic value for the variability, the seismic risk is estimated by convolution of the hazard and the fragility curve. Critical importance is attached to the selection of the plant capacity in terms of the HCLPF, without performing extensive fragility calculations of seismically relevant SSC's. A suitable basis

Embedded systems often have real-time constraints. Traditional timing analysis statically determines the maximum execution time of a task or a program in a real-time system. These systems typically depend on the worst-case execution time of tasks in order to make static scheduling decisions so that tasks can meet their deadlines. Static determination of worst-case execution times imposes numerous restrictions on real-time programs, which include that the maximum number of iterations of each loop must be known statically. These restrictions can significantly limit the class of programs that would be suitable for a real-time embedded system. This paper describes work-in-progress that uses static timing analysis to aid in making dynamic scheduling decisions. For instance, different algorithms with varying levels of accuracy may be selected based on the algorithm's predicted worst-case execution time and the time allotted for the task. We represent the worst-case execution time of a function or a loop as a formula, where the unknown values affecting the execution time are parameterized. This parametric timing analysis produces formulas that can then be quickly evaluated at run-time so dynamic scheduling decisions can be made with little overhead. Benefits of this work include expanding the class of applications that can be used in a real-time system, improving the accuracy of dynamic scheduling decisions, and more effective utilization of system resources. This paper describes how static timing analysis can be used to aid in making dynamic scheduling decisions. The WCET of a function or a loop is represented as a formula, where the values affecting the execution time are parameterized. Such formulas can then be quickly evaluated at run-time so dynamic scheduling decisions can be made when scheduling a task or choosing algorithms within a task. Benefits of this parametric timing analysis include expanding the class of applications that can be used in a real

This report documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain, Nevada, the site of a repository for spent nuclear fuel and high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this report provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the following reports: ''Simulation of Net Infiltration for Present-Day and Potential Future Climates'' (BSC 2004 [DIRS 170007]), ''Total System Performance Assessment (TSPA) Model/Analysis for the License Application'' (BSC 2004 [DIRS 168504]), ''Features, Events, and Processes in UZ Flow and Transport'' (BSC 2004 [DIRS 170012]), and ''Features, Events, and Processes in SZ Flow and Transport'' (BSC 2004 [DIRS 170013]).

The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. While alternative analyses are possible for the case presented for Yucca Mountain, the evidence (data) used would be the same and the conclusions would not be expected to drastically change.

Full Text Available Initial stability at the placement and development of osseointegration are two major issues for implant survival. Implant stability is a mechanical phenomenon which is related to the local bone quality and quantity, type of implant, and placement technique used. The application of a simple, clinically applicable, non-invasive test to assess implant stability and osseointegration is considered highly desirable. Resonance frequency analysis (RFA is one of such techniques which is most frequently used now days. The aim of this paper was to review and analyze critically the current available literature in the field of RFA, and to also discuss based on scientific evidence, the prognostic value of RFA to detect implants at risk of failure. A search was made using the PubMed database to find all the literature published on "Resonance frequency analysis for implant stability" till date. Articles discussed in vivo or in vitro studies comparing RFA with other methods of implant stability measurement and articles discussing its reliability were thoroughly reviewed and discussed. A limited number of clinical reports were found. Various studies have demonstrated the feasibility and predictability of the technique. However, most of these articles are based on retrospective data or uncontrolled cases. Randomized, prospective, parallel-armed longitudinal human trials are based on short-term results and long-term follow up are still scarce in this field. Nonetheless, from available literature, it may be concluded that RFA technique evaluates implant stability as a function of stiffness of the implant bone interface and is influenced by factors such as bone type, exposed implant height above the alveolar crest. Resonance frequency analysis could serve as a non-invasive diagnostic tool for detecting the implant stability of dental implants during the healing stages and in subsequent routine follow up care after treatment.

In this strategy, Buckingham's theorem is seen as a consequence and not as the starting point. In order to concentrate on the basics, the mathematics is kept as elementary as possible. Simple examples are suggested for classroom demonstrations of the power of the technique and others are put forward for homework or experimentation, but instructors are encouraged to produce examples of their own.

Elementary Heat Transfer Analysis provides information pertinent to the fundamental aspects of the nature of transient heat conduction. This book presents a thorough understanding of the thermal energy equation and its application to boundary layer flows and confined and unconfined turbulent flows. Organized into nine chapters, this book begins with an overview of the use of heat transfer coefficients in formulating the flux condition at phase interface. This text then explains the specification as well as application of flux boundary conditions. Other chapters consider a derivation of the tra
