Chuang, Chi Ming. "Extraction of programs for exact number computation using Agda." Thesis, Swansea University, 2011. https://cronfa.swan.ac.uk/Record/cronfa42274.
Full textAbstract:
This thesis contains the to our knowledge first research project to ex-tract in the theorem prover Agda programs from proofs involving pos-tulated axioms. Our method doesn't require to write a Meta program for extracting programs from proofs. It shows as well the correctness of the machinery. This method has been applied to the extraction of programs about real number computation. The method has been used for showing that the signed digit approximable real numbers are closed under addition, multiplication, and contain the rational numbers. Therefore we obtain in Agda a provably correct program which executes the corresponding operations on signed digit streams. The first part of the thesis introduces axioms about real numbers using postulated data types and functions in Agda without giving any computational rules. Then we investigate some properties of real numbers constructed by Cauchy sequences: we introduce the set of real numbers which are limits of Cauchy sequences of rational numbers (Cauchy Reals) and show that they are closed under addition and multiplication. We also prove that Cauchy Reals are Cauchy complete. Furthermore, we introduce the real numbers in the interval [-1,1], which have a binary signed digit representation, i.e. r = 0.d0d1d2..., where di ∈ {-1, 0, 1}. This set of real numbers is given as a codata type (SDR). We determine for rational numbers in the interval [-1, 1] their SDR and show that SDRs are closed under the average function and the multiplication function. Besides, a finding digit function is defined which determines the first n digits of a stream of signed digits. In the second part of the thesis, a theorem is given which shows the correctness of our method. It shows that under certain conditions our method always normalises and doesn't make use of the axioms. The conditions mainly guarantee that a postulated function or axiom has as result type only a postulated type, so the reduction of elements of algebraic data types to head normal form will not refer to these postulates. Because of our theorem the finding digit function applied to a real number r s.t. SDR r holds normalises to [do, d1,..., dn-1] for the first n digit d0d1...dn-1 of r. Therefore, we can compute the SDR of rational numbers and from SDRs of real numbers the SDR of their average and product.

Oladimeji, Patrick. "Designing number entry user interfaces : a focus on interactive medical devices." Thesis, Swansea University, 2014. https://cronfa.swan.ac.uk/Record/cronfa42894.
Full textAbstract:
Number entry is a crucial aspect of using many interactive systems. Tasks such as withdrawing money from an ATM, selecting a TV channel, manually tuning into a radio station, or setting up an infusion pump for drug delivery, all involve entering or selecting numbers. The number entry aspects of these tasks are usually secondary to the user's goal. Users typically have higher level goals which might involve a sub-task related to entering numbers. As a result, number entry is assumed to be simple, straight forward and uninteresting. The design of number entry interfaces dates back as early as the use of tally sticks and counting boards although modern interfaces did not emerge until the design of the first mechanical calculator in the 17th century. The nature of numbers allows interfaces to be designed that exploit the specification of individual digits of the number as well as making incremental changes to the entire number. The diversity in interface design is not evident in current research which is dominated by various forms of evaluations of the numeric keypad interface. This thesis undertakes a historical review of the design of number entry interfaces and then explores the design space within which they lie while proposing a classification for the different styles of interfaces. It then evaluates several example alternatives to the numeric keypad, specifically those in use on infusion pumps in hospitals using both exhaustive simulations and usability studies. These evaluations explore the effects of interface styles on error detection, speed, error severity and error type. This research concludes by identifying properties for performing relative comparisons of interfaces and uncovers design trade-offs th at will help inform decisions about the safety and dependability of number entry interfaces.

Full textAbstract:
User interfaces that employ the same display and buttons may look the same but can work very differently depending on how they are implemented. In healthcare, it is critical that interfaces that look the same are the same. Hospitals typically have many types of visually similar infusion pumps, but with different software versions and variation between pump behaviour, and this may lead to unexpected adverse events. For example, when entering drug doses into two similar infusion pumps, different results may arise when pushing identical sequences of buttons. These differences arise as a result of subtle implementation differences and may lead to large errors that users do not notice. 'Differential formal analysis' is a new user interface analytic evaluation method based on stochastic user simulation. The method is particularly valuable for helping evaluate safety critical user interfaces, which often have subtle programming issues. This new approach starts with the identification of operational design features that define the design space to be explored. All combinations of design features are analysed by simulating keystroke sequences containing keying slip errors. Finally, each simulation produces numerical values that rank the design combinations on the basis of their sensitivity to key slip errors. Differential formal analysis is demonstrated through case studies of number entry systems, many of which represent a common safety-critical user interface styles found in medical infusion pumps and elsewhere. The results uncover critical design issues, and are an important contribution of this thesis since the results provide device manufacturers guidelines to improve their device firmware. The analysis is complemented with models of usage based on 1,362 days of use of number entry systems from 19 infusion pumps over a 3 year period in a UK hospital. This thesis also suggests some improvements to medical device logging, which will help further evidence-based improvement to medical device safety. Previously, empirical methods and analytic methods have been used independently to analyse and improve number entry system designs. This thesis identifies key contrasts in exploring number entry errors using laboratory studies and analytic methods. The implications of combining methods to more thoroughly analyse safety critical design are discussed.

Tyacke, James C. "Low Reynolds number heat transfer prediction employing large eddy simulation for electronics geometrics." Thesis, Swansea University, 2009. https://cronfa.swan.ac.uk/Record/cronfa42811.
Full textAbstract:
The accurate prediction of convective heat transfer within electronics systems has always been of great importance for the reliability of such systems. Current computational methods based on the Reynolds-Averaged Navier-Stokes equations do not provide reliable predictions due to the inability of current methods to capture complex time dependent flow features. This study investigates the use of time dependent Large Eddy Simulation and hybrid methods to make more reliable thermal predictions. These methods are tested on a heated ribbed channel, a heated cube in an array of cubes and a complex CPU case. A variety of models and methodologies are applied and analysed. It is apparent that the most important scales are the large vortices generated by geometrical features. Due to the low Reynolds number flows found in electronics systems, there is a relatively small range of scales to capture. This gives rise to some unpredictability in model choice and grid resolution, though consistency is much improved over traditional methods. Important sources of error are considered to be problem definition and boundary conditions for which unsteady data is not available. Use of nonlinear models and higher order discretisation did not provide adequate improvements in accuracy for the increase in computational expense. Combining Reynolds-Averaged Navier-Stokes and Implicit Large Eddy Simulation into a hybrid model seems to provide fair reliability when compared to other modelling methods on a range of grid resolutions.

Full textAbstract:
Abstract. Today the digital means of communication are evolving rapidly, resulting in more improved and reliable ways of communication. Now the information can be shared or collected instantly, which means the impact through information collection and processing can be faster too. The digital means of research dissemination are enabling people to share their work instantly and gather the attention a lot quicker than the past. The faster means of communication also enabled the researchers to share their scholarly work instantly to extensive and broader addressees. The faster and instant means also empowered to quantify the impact of research works shared or disseminated digitally. Thus, to determining the impact generated by the disseminated academic work over the internet a contemporary or well suited and up to date or alternative approach was required to measure exact or nearly related impact of research outputs disseminated over the web.
The requirements for measurement of the research impact over the web enabled platforms the initiate for the introduction and implementation alternative metrics was started in the last decade. Since its advent, the altmetrics has achieved various milestones regarding the measurement of research impact. The altmetrics is an alternative metric to complement the traditional citation-based approach provided another perspective for the researchers to see the visibility and the impression of research work mentioned or disseminated on web platforms. The altmetrics opened an impressive opportunity for the researchers to determine the impact of their work instantly, alongside the opportunities provided by the altmetrics there are limitations too, which hindered its progress to completely replace the traditional approaches to measure the research impact both qualitatively and quantitatively.
In this thesis study the aim was established to evaluate the altmetrics as a substitutive platform for the quantification and measurement of research influence gathered over the internet. By utilizing literature review approach this study collected most relevant research articles and analysed the collected literature to answer the proposed questions in this thesis study.
The results are collected to evaluate the altmetrics as an alternative research impact measuring platform and what does the altmetrics attention score tells us about a disseminated research work. The study found the major opportunities offered by the altmetrics and the limitations for the adaptability of altmetrics as a complete alternative approach. Conclusively, study found that the adoption of altmetrics will take time and the due to existing limitations. The alternative metrics approach or the altmetrics can balance the existing citation-based approaches but can’t completely replace them. The altmetric attention score and other indicators provided by altmetrics could be a good early indicator of the research outputs to determine the future impact of disseminated scholarly work.

Full textAbstract:
Abstract. The consequences of tourist activities on host communities have recently gained more and more attention. In many cities the local population has started to complain about tourism negatively impacting their quality of life [Qol]. Therefore, it is important to collect information about which parts of the Qol are endangered since the local population plays a major role in the tourism sector of a country.
In the present study the local population of the Irish capital Dublin serves as the case of research. This is appropriate since the friendliness and the hospitality of the local population in Ireland is one of the most important reasons for visiting the country. Moreover, Dublin has recorded strong increases in tourist numbers over the last years.
The concept of the Qol and the social impact research in tourism serve as the theoretical framework for this study. It is investigated how tourism impacts on different areas of the Qol and how these are subjectively perceived. For that reason, the following research question is derived:
How are the increasing tourist numbers in Dublin influencing the quality of life of the local population?
A quantitative approach was chosen to answer this question and to verify the derived hypotheses. The data was collected via an online survey, which was directed to people currently living in Dublin.
It was found out that tourism impacts on the Qol in Dublin are not dependent on the district where the participants live and for how long the participants have been living there. However, it was identified that people who are working in tourism perceive stronger impacts of tourism and that the perception of economic factors plays an important role in the overall satisfaction with the Qol. Concluding, it can be said that the subjective perception of the Qol was rated as good by a large share of the participants.
The study has practical implications since it contributes to an understanding of the locals’ present perception of the Qol in Dublin. This information can be used to take countermeasures early in case the residents’ attitude towards tourists seems to shift.

Philosophiae Doctor - PhDThe advantage of a well-developed health information system is the significant role played by records produced by such a system beyond recording medical history of individuals. They are the foundation for birth registrations which when fully complete is an important tool for acquiring data necessary for planning and monitoring child and maternal health in a country. This study aimed to investigate the potential of hospital birth records to estimate the number of births in the country and supplement birth registrations data. Data was abstracted from public facilities where births occur in two municipalities; Germiston in Gauteng and Nkomazi in Mpumalanga for the period 2014 to 2016. Modified version of the BORN Data Quality Framework (BORN-DQF) of the Ontario Agency for Health Protection and Promotion (2016) was used to assess the contents and quality of hospital birth records.

Stochastic fluctuations in mRNA and protein copy number between cells are inevitable during the process gene expression, even when cells carry identical chromosomes. Such fluctuations are able to impact the phenotypic fate of the cell, and are known to have greater impact when the copy number of the molecule involved is low. Additionally, up to 50% of proteins in Escherichia coli are present in the cell at a level of 10 molecules per cell or fewer (Taniguchi et al. 2010). As such, quantification of low copy number gene expression products and their distribution in cellular populations is key in understanding the process of gene expression. Currently, there are few techniques that allow investigation with the single cell and single molecule resolution required to study low copy number gene expression products. This work presents a novel method for protein quantification at the single molecule level, Quantitative HaloTag-TMR labelling, and uses the technique to quantify the absolute numbers of the low copy number RecB, RecC and RecD subunits of the bacterial DNA repair enzyme RecBCD, finding each subunit is present at between two and eight molecules per cell with mean numbers per cell of 4.9, 4.7 and 4.5 respectively. Additionally single molecule mRNA FISH was used to quantify the mRNA levels of recB and recD within cells, with means of 0.21 and 0.31 mRNA per cell being observed respectively. Finally this work presents a new method for use detecting both mRNA and protein simultaneously in individual cells by combining the HaloTag and FISH protocols to give HaloFISH. This work introduces two novel techniques that allow for single cell examination of gene expression, and investigates RecBCD expression at the single molecule level.

Dat je predlog nove metode generisanja šuma uniformne raspodele amplituda. Umesto uobičajenog načina generisanja korišćenjem generatora pseudoslučajnih brojeva i D/A konvertora, ovde se predlaže generisanje zasnovano na neuniformnom odabiranju testerastog ili trougaonog napona. Osim uštede zbog nekorišćenja D/A konvertora, dobit je i mogućnost generisanja napona iz kontinualnog, umesto diskretnog skupa amplituda. Većina današnjih hardverskih generatora pseudoslučajnog napona, se bazira na upotrebi mikrokontrolera i D/A konvertora, pa je na taj način rezolucija generisanja pseudoslučajnog napona ograničena rezolucijom D/A konvertora. Odabiranjem testerastog ili trougaonog napona predloženom metodom se ostvaruje gotovo neograničena rezolucija.

The dissertation investigates the impact of the application of the dithering signal (discrete analogue uniform noise) generated by the new method for increasing the effective resolution of measurement instruments based on the stochastic digital measurement method. The dissertation provides an overview of the existing solutions based on the stochastic digital measurement method in order to understand the need and justification of the research. The proposed solution represents a combination of a pseudorandom and truly random generator and as such holds the best features in both areas. А suggestion of a new way of generating the noise of the uniform distribution of amplitudes is presented. Instead of the usual way of generating using a pseudorandom number generator and a D/A converter, the generation based on the nonuniform sampling of sawtooth or triangle voltage is proposed. In addition to the savings due to the non-use of a D/A converter, the possibility of generating voltages from a continual instead of a discrete amplitude set is also obtained. Most of today's hardware pseudorandom voltage generators are based on the use of a microcontroller and D/A converter, so in this way the resolution of the pseudorandom voltage generation is limited by the resolution of the D/A converter. By sampling the sawtooth or triangle voltage using the proposed method, almost unlimited resolution is achieved. The use of this generated dither signal leads to an increase in effective resolution in stochastic measuring instruments. The simulation determined the optimal structure of the generator based on the proposed method. Experimental measurements were made using developed hardware.

Саобраћајно-географски и стратешки положај Книнске Крајине, условљавају сталну присутност овог подручја у балканским и европским збивањима, мада значај природних потенцијала није томе адекватан. Овим простором су пролазиле многе војске и владале бројне империје. Кроз бурне догађаје неки природни елементи су деградирани (вегетација, земљиште, укупан пејсаж), а дешавале су се и потпуне смене становништва, те рушења и паљења, што се веома негативно одражавало на привредну активност. Виталност становништва дуго је успешно надокнађивала стална исељавања. Међутим, стално погоршавање укупних природно-друштвених елемената, као и савремени привредни токови, поспешили су процес исељавања, па је крајем двадесетог века број становника у многим насељима пао на ниво из средине деветнаестог века. Сточарство је вековима било доминантна активност, али су деградација природне средине, слаба улагања и стално исељавање утицали на знатно опадање значаја ове гране. Ипак за равномеран развој, осим индустријализације, мора бити добро организована и пољопривредна производња. Пољопривредна делатност, на овом простору, мора тражити своју будућност и у производњи здраве хране, како у ратарству тако и у сточарству. Концентрација индустрије у Книну није добра за равномеран развој, а пошто изградња малих погона у неколико мањих наеља показује позитивне ефекте, мора се наставити у том правцу. Територијалне и политичке промене на простору бивше СФРЈ, утичу на појачање централних функција Книна, те он постаје значајан међурегионални и републички центар. Побољшању укупног развоја треба да допринесе и туристичка привреда, али и правилно валоризовање саобраћајног положаја и неких природних богатстава. Да би што боље оживела сеоска насеља, мора се побољшати функционално-комунална опремљеност локалних центара.Saobraćajno-geografski i strateški položaj Kninske Krajine, uslovljavaju stalnu prisutnost ovog područja u balkanskim i evropskim zbivanjima, mada značaj prirodnih potencijala nije tome adekvatan. Ovim prostorom su prolazile mnoge vojske i vladale brojne imperije. Kroz burne događaje neki prirodni elementi su degradirani (vegetacija, zemljište, ukupan pejsaž), a dešavale su se i potpune smene stanovništva, te rušenja i paljenja, što se veoma negativno odražavalo na privrednu aktivnost. Vitalnost stanovništva dugo je uspešno nadoknađivala stalna iseljavanja. Međutim, stalno pogoršavanje ukupnih prirodno-društvenih elemenata, kao i savremeni privredni tokovi, pospešili su proces iseljavanja, pa je krajem dvadesetog veka broj stanovnika u mnogim naseljima pao na nivo iz sredine devetnaestog veka. Stočarstvo je vekovima bilo dominantna aktivnost, ali su degradacija prirodne sredine, slaba ulaganja i stalno iseljavanje uticali na znatno opadanje značaja ove grane. Ipak za ravnomeran razvoj, osim industrijalizacije, mora biti dobro organizovana i poljoprivredna proizvodnja. Poljoprivredna delatnost, na ovom prostoru, mora tražiti svoju budućnost i u proizvodnji zdrave hrane, kako u ratarstvu tako i u stočarstvu. Koncentracija industrije u Kninu nije dobra za ravnomeran razvoj, a pošto izgradnja malih pogona u nekoliko manjih naelja pokazuje pozitivne efekte, mora se nastaviti u tom pravcu. Teritorijalne i političke promene na prostoru bivše SFRJ, utiču na pojačanje centralnih funkcija Knina, te on postaje značajan međuregionalni i republički centar. Poboljšanju ukupnog razvoja treba da doprinese i turistička privreda, ali i pravilno valorizovanje saobraćajnog položaja i nekih prirodnih bogatstava. Da bi što bolje oživela seoska naselja, mora se poboljšati funkcionalno-komunalna opremljenost lokalnih centara.
The regional trafffic, geographic and strategic position of Knin Krajina was the main cause for its constant presence in Balcan and European events, though the inportantce its natural resources had not been adequate. Many armies passed through this region and a number of empires ruled it. Thruogh the turmoils of these events some natural elements were degraded (vegetation, soil, the whole scenery), total changes in its population emerged, destructions and arsons which had an-extremely negative effect on public economy. Vitality of the population had for a long time been successful in substituting for the constant migrations. However, constant deteriorating of natural and social elements, as well as modem natural movements, had influenced the speed of depopulation process, so that at the end of the XX centry a number of people in many settlements had decreased to the level equal to the middle XIX century period. Forming used to be dominant for centuries but the degradation of the nature and its qualities, poor investments and constant depopulation had affested it and made it inferior. Still, in order to have a balanced growth, apart from industralisation and agricultural production also needed to be very well organised. Agriculture, in this area, had to search for its future prospects in production of healthy food, both in cattle-breeding and in farming. The concentrated industry in Knin is not sufficiently good for a balanced growth and since building of new little factories in a few of small communities has showed positive effects, this direction should be followed. Changes in territory and in politics in the area of exYugoslavia, affects the increasing growth of central functions in Knin and therefore it has become an important internacional and republic center. Tourism should also contribute to the total development, and a proper evaluation of its traffic position and some natural resources as well. To make village communities more active some functional and communal facilities in local centres have to be improved.

Il lavoro è stato suddiviso in tre macro-aree.
Una prima riguardante un'analisi teorica di come funzionano le intrusioni, di quali software vengono utilizzati per compierle, e di come proteggersi (usando i dispositivi che in termine generico si possono riconoscere come i firewall).
Una seconda macro-area che analizza un'intrusione avvenuta dall'esterno verso dei server sensibili di una rete LAN.
Questa analisi viene condotta sui file catturati dalle due interfacce di rete configurate in modalità promiscua su una sonda presente nella LAN.
Le interfacce sono due per potersi interfacciare a due segmenti di LAN aventi due maschere
di sotto-rete differenti. L'attacco viene analizzato mediante vari software.
Si può infatti definire una terza parte del lavoro, la parte dove vengono analizzati i file
catturati dalle due interfacce con i software che prima si occupano di analizzare i dati di
contenuto completo, come Wireshark, poi dei software che si occupano di analizzare i dati di
sessione che sono stati trattati con Argus, e infine i dati di tipo statistico che sono stati trattati
con Ntop.
Il penultimo capitolo, quello prima delle conclusioni, invece tratta l'installazione di Nagios, e
la sua configurazione per il monitoraggio attraverso plugin dello spazio di disco rimanente su
una macchina agent remota, e sui servizi MySql e DNS. Ovviamente Nagios può essere
configurato per monitorare ogni tipo di servizio offerto sulla rete.

Full textAbstract:
La tesis se encarga de analizar, por un lado, la integración y el desarrollo de las nuevas tecnologías en la Administración de Justicia; y, por otro, los parámetros que constituyen la validez y eficacia del documento electrónico. La primera cuestión se centra en la configuración de los Sistemas de Información de la Oficina Judicial y del Ministerio Fiscal, así como de la informatización de los Registros Civiles, donde el art. 230 LOPJ es la pieza clave. Se estudian sus programas, aplicaciones, la videoconferencia, los ficheros judiciales y las redes de telecomunicaciones que poseen la cobertura de la firma electrónica reconocida, donde cobran gran relevancia los convenios de colaboración tecnológica. La digitalización de las vistas quizá sea una de las cuestiones con más trascendencia, teniendo en cuenta que el juicio es el acto que culmina el proceso. Aunque no todos los proyectos adoptados en el ámbito de la e.justicia se han desarrollado de forma integral, ni han llegado a la totalidad de los órganos judiciales. El objetivo final es lograr una Justicia más ágil y de calidad, a lo cual aspira el Plan Estratégico de Modernización de la Justicia 2009-2012 aprobado recientemente.
En referencia a la segunda perspectiva, no cabe duda que el Ordenamiento jurídico y los tribunales, en el ámbito de la justicia material, otorgan plena validez y eficacia al documento electrónico. Nuestra línea de investigación se justifica porque cada vez son más los procesos que incorporan soportes electrónicos de todo tipo, ya sea al plantearse la acción o posteriormente como medio de prueba (art. 299.2 LEC). Entre otros temas examinamos el documento informático, la problemática que rodea al fax, los sistemas de videograbación y el contrato electrónico.
La tesi s'encarrega d'analitzar, per una part, la integració i el desenvolupament de les noves tecnologies dins l´Administració de Justícia; i, per l'altra, els paràmetres que constitueixen la validesa i l'eficàcia del document electrònic.
La primera qüestió es centra en la configuració dels Sistemes d´Informació de l´Oficina Judicial i del Ministeri Fiscal, així com de la informatització dels Registres Civils, on l'art. 230 LOPJ es la peça clau. S'estudien els seus programes, aplicacions, la videoconferència, el fitxers judicials i les xarxes de telecomunicacions que tenen la cobertura de la firma electrònica reconeguda, on cobren gran rellevància els convenis de col·laboració tecnològica. La digitalització de les vistes tal vegada sigui una de les qüestions amb més transcendència, tenint amb compte que el judici es l'acte que culmina el procés. Però no tots el projectes adoptats en l'àmbit de la e.justicia s'han desenvolupat d'una manera integral ni han arribat a la totalitat dels òrgans judicials. L'objectiu final es assolir una Justícia més àgil i de qualitat, al que aspira el Pla Estratègic de Modernització de la Justícia 2009-2012 aprovat recentment.
En referència a la segona perspectiva, no hi ha dubte que l´Ordenament jurídic i els tribunals, en l'àmbit de la justícia material, donen plena validesa i eficàcia al document electrònic. La nostra línia d'investigació es justifica perquè cada vegada son més el processos que incorporen suports electrònics de tot tipus, ja sigui quant es planteja l'acció o posteriorment como a medi de prova (art. 299.2 LEC). Entre altres temes examinem el document informàtic, la problemàtica que envolta al fax, els sistemes de videogravació i el contracte electrònic.
The thesis seeks to analyse, on the one hand, the integration and development of the new technologies in the Administration of Justice; and, on the other, the parameters which constitute the validity and efficiency of the electronic document.
The first question centres on the configuration of the Information Systems of the Judicial Office and the Public Prosecutor, as well as the computerisation of the Civil Registers, where the art. 230 LOPJ it's the part key. Their programmes, applications, the Video Conferencing, the judicial registers and the telecommunication networks which are covered by the recognised electronic signatures, are studied, where the agreements on technological collaboration gain great relevance. The digitalisation of evidence might perhaps be one of the questions with most consequence, bearing in mind that the judgment is the act by which the process is culminated. Although not all the projects adopted within the compass of e.justice have developed completely nor have reached all the judicial organs. The final objective is to achieve an agile, quality Justice, to which the recently approved Strategic Plan for the Modernisation of Justice aspires.
With reference to the second perspective, there is no doubt that the juridical Ordinance and the tribunals within the compass of material justice grant full validity and efficacy to the electronic document. Our line of investigation is justified because there are more and more processes which are sustained by electronic supports of all kinds, whether it be at the establishment of the action or later, as a proof of it (art. 299.2 LEC). Amongst other things, we examine the computerised document, the problems which surround the fax, the systems for video recording and the electronic contract.

"The number-location association and its marketing implication." Thesis, 2010. http://library.cuhk.edu.hk/record=b6075297.
Full textAbstract:
At last, this dissertation considers another marketing implication of this number-location association, namely the compatibility effect. In experiment 7, we find that people perceive a discount as more attractive when the two prices are actually posited in compatible locations (original price-right side; discounted price-left side) than in incompatible locations. Similarly, experiment 8 demonstrates that people are more likely to patronage a supermarket when the supermarket's slogan about low price is shown on the left side of a display than on the right side, and this effect is mediated by the subjective fluency feeling people felt at the time they process the advertisement.Given a display, people usually think that large numbers should be located on the top or on the right hand side of the display, whereas small numbers should be posited at the bottom or on the left (Wood and Fischer 2008).
Given this number-location association, this dissertation secondly intends to apply it to the field of marketing, and to use three experiments to explore how and why location of product image can influence people's price judgment. The results of experiment 4 show that consumers think that the market price of a product is higher if the product's image is shown on the right side of a display than on the left side; experiment 5 and experiment 6 further indicate that the location of product image can only influence consumers' price judgment, but cannot influence quality judgment.
Key Words: Number-location association, Simulation, Perceptual Symbol Systems (PSS), Price perception.
This dissertation firstly aims to provide new evidence for this number-location association. Experiment 1 demonstrates that people incorrectly remember that large numbers appear to the right of the locations they actually were shown while small numbers appear to the left ofthe locations than they actually were presented; experiment 2 and experiment 3 show that people estimate there are more pieces in a pile of object when the pile of object is presented on the right side of a display than on the left side.

Full textAbstract:
In this thesis, we consider the non-uniqueness of weak solutions to the compressible isentropic Euler equations on a bounded domain. We establish a criterion for the existence of infinitely many solutions with the same initial data. Using this criterion, we prove that for general smooth initial density and velocity, there exists infinitely many weak solutions. Furthermore, given smooth initial density bounded away from zero, we can construct a initial velocity field such taht there exists infinitely many weak solutions with this initial data, and these solutions satisfy the entropy inequality for a positive finite time. The results also generalizes to the free boundary value problems.本論文考慮可壓等熵歐拉方程在有界區域上其弱解的非唯一性。我們建立了關於存在無窮多個有同一初始狀態的弱解的判別準則。利用此準則，我們證明了對於一般的光滑的初始密度和速度場，存在無窮多個弱解:進一步的，對於光滑有正下界的初始密度場，我們構造了一小初始速度場，證明存在滿足這樣初始資料的無窮多個弱解，並且，在一個有限時間內，這些弱解滿足熵不等式。這些結果可以推廣到自由邊界情形。

"Dynamics of the large-scale circulation in high prandtl number turbulent Rayleigh-Bénard convection." 2012. http://library.cuhk.edu.hk/record=b5549085.
Full textAbstract:
自然界中存在很多的湍流熱對流現象。他們對於工業，科學與技術有著非常重要的影響。在本論文中我們利用多温度探头的技术研究了湍流熱對流的理想模型-湍流瑞利-伯納德對流中的大尺度環流在高普朗特數下的動力學特性。實驗中，我们利用水和電子液體FC77 作為工作物質，獲得了普朗特數Pr 從5.3 到19.4. 瑞利數Ra 範圍8.3 × 10⁸ 2.94 × 10¹¹.我們用了一個寬高比Γ 為1 的圓柱形對流槽來研究大尺度環流的動力學特性。我們發現，在高普朗特數的時候，大尺度環流仍然是一個single roll. 這個與我們期望的是一樣的。大尺度環流的強度δ 的概率密度函數是一個高斯分佈。但是左邊的尾巴可以用一個指數函數來描述。我們也觀察到了大尺度環流傾向於呆在一個特定的角向位置。我們還發現，大尺度流動的角向運動具有擴散運動的特性。但是，用FC77 作為工作物質時，這個角向運動的擴散係數比用水作為工作物質時小兩個量級。實驗中測量到的雷諾數Re 和瑞利數Ra 之間的標度率與之前的實驗結果相符合。同時這個標度率也和Grossman-Lohse 模型的預測相符合。
大尺度流動豐富的動力學特性，比如說流動停止，流向反轉，扭轉還有平移振盪以及流動模式轉換，都可以在高普朗特數的時候觀察到。比較有趣的是我們發現流動停止在一個三維系統中既不依賴於Ra, 又不依賴於Pr. 這個結果和二維的瑞利-伯納德對流完全不同。
Turbulent thermal convection is of tremendous importance to many areas of science, technology as well as the environment. In this thesis, the dynamics of the large-scale circulation (LSC) in turbulent Rayleigh-B´enard convection, which is an idealised model to study turbulent thermal convection problem, is investigated using the multi-thermal probe technique in the high Prandtl number Pr regime.
Using two kinds of working fluids, namely water and Fluorinert FC77, we achieved Pr from 5.3 to 19.4 and Rayleigh number Ra from 8.3×10⁸ to 2.94×10¹¹. The dynamics of the LSC is measured in an aspect ratio unity convection cell. It is found that the LSC in the high Pr regime is a single roll structure as expected. The probability distribution of the flow strength δ is a Gaussian distribution function with exponential tail to the left. The preferred orientation is also observed, which is revealed by the PDF of azimuthal orientation θ of the LSC. The azimuthal motion of the LSC is a diffusive process, which is the same as previous studies. However, we found that the diffusivity of the angular speed using FC77 as the working fluid is two orders smaller than using water as working fluid. The scaling of the measured Reynolds number Re number based on the oscillation frequency of the LSC with respect to Ra is in good agreement with previous experimental results and also Grossman-Lohse model prediction.
The abundant dynamical features of the LSC, such as cessations, flow reversals, torsional and sloshing oscillations and flow mode transitions are also observed in the high Pr regime. One surprising finding is that the cessation frequency of the LSC ,based on the statistics of the mid-height level of thermistors, is independent of both Ra and Pr, which is quite different from the (quasi) two-dimensional turbulent Rayleigh-B´enard convection.
