The work deals with main aspects of computer efficiency increase. Object of investigation is a system consisting of processor, memory, other components and connecting links called buses. Rather different systems are used in modern world of information, so an interest arises to compare architectures of several producers. Comparison of systems is quite possible as the same architectural features bind them together: processor‘s clock speed, cache, memory, dual channel technology and others. To perform a comparative analysis, software has been used enabling to reveal increase of efficiency of separate computer components. Systems chosen for study are rather new from the point of view of technology: Intel Pentium 4, AMD Athlon XP and AMD Sempron. Experiments having been fulfilled, it came out that efficiency of a system for the most part depends on processor capacity: increase of its clock speed results in 9 – 13%, L1 cache has an effect even up to 1350% (theoretically), L2 cache – 30 – 38%. HyperThreading has been observed to mostly result in operations with floating point numbers (even up to 68%), and branch prediction would have theoretically to increase efficiency up to 47%. Estimating indicator of efficiency of the whole system, the results show that the main role belongs to processor. Influence of other components of the system is less noticeable. Working peculiarities of memory type determine rate of data selection and transmission from memory. The study has shown that... [to full text]

Arkinės perdangos dėl savo veiksmingumo yra dažnos šiuolaikiniuose pėsčiųjų tiltuose. Racionali apybrėžos forma (dažniausiai kvadratinė parabolė) lemia šių konstrukcijų racionalų įrąžų pasiskirstymą. Arkų eksploatacinio funkcionavimo pagrindinis bruožas yra tas, kad vertikaliosios apkrovos, be vertikalių reakcijų paduose, sukelia ir horizontalias reakcijas (skėtimo jėgas). Be tradicinių arkinių perdangų iš istorijos šaltinių yra žinoma ir unikalios sandaros arkinių lęšio formos tiltų. Jie reikšmingi ne tik dėl savo unikalios formos, bet ir dėl istorinės vertės, nes buvo statomi du paskutinius XIX a. dešimtmečius, kaip dinozaurai mėgavosi savo istorine epocha prieš daug, daug metų ir tada staiga išnyko. Darbe atliekama tradicinio arkinio tilto, bei arkinių plieninių lęšio formos tiltų elgsenos analizė, keičiant pagrindinius geometrinius arkų – juostų parametrus, arkų tinklelio formą ir tinkleliui taikant išankstinį įtempimą. Pirmame skyriuje aptariama arkinių ir arkinių kombinuotųjų tiltų konstrukcinės schemos, jų skaičiavimo metodai. Formuluojami darbo tikslas ir uždaviniai. Antrame skyriuje atliekama tradicinio arkinio tilto ir arkinių abipusiai iškilos formos tiltų elgsenos analizė, veikiant simetrinėms ir asimetrinėms apkrovoms. Trečiame skyriuje atliekama gautų rezultatų lyginamoji analizė, lyginant tiltų konstrukcijas pagal įrąžų pasiskirstymą jų elementuose ir pagal tiltų masės kriterijų. / Due to their effectiveness, arched entablatures are common in modern footbridges. Well-balanced form of contour (most commonly quadratic parable) determines a well-balanced stress distribution of these constructions. The main feature of the running behaviour of arcs is that vertical loads without vertical reactions in the hearths create horizontal reactions as well (forces of thrust). Not only traditional bridges with arched entablatures but also unique structured arched lenticular bridges. They are significant not only for its unique shape and few examples but also for the historic value that they were only built during the last two dacedes of 19th century, like dinasors had enjoyed a historic age long long ago and then suddenly vanished at all. In this work carries out the analysis of behaviour of traditional arched bridge and arched lenticular bridges made of stell by changing the main geometric parameters of arcs-strips, form of the system of arcs and applying pre-stress of the system. The first chapter discusses the schemes of construction of arched and arched combined bridges, methods of their calculation. The goal and tasks of the work are formulated. The analysis of the behaviour of traditional arched bridge and arched lenticular bridges (when it is affected by symmetric and asymmetric loads) is carried out in the second chapter. Comparative analysis of the results is performed in the third chapter by comparing constructions of the bridges according to stress... [to full text]

Uppsatsen utforskar legenden om den helige Antonius frestelse och det intryck helgonberättelsen lämnat på konsten. En ikonografisk metod används för att beskriva den litteratur som skapat och utvecklat berättelsen och ur detta systematiseras de motiv som sedan översatts till bildkonsten. Genom att analysera nio olika avbildningar av Antonius skapas en kronologisk följd över hur skildringarna genomgått en transformation sedan 1500-talet. / This thesis explores the legend of Saint Anthony and his temptations, and the impression his hagiography has left on the visual arts. An iconographic method is employed to investigate literature connected to the origin and later evolution of the story, which is used to classify motifs and concepts subsequently translated into painting. Via analysis of nine different depictions of Anthony, a chronological sequence is formed which lists the transformation these portrayals have undergone since the 16th century.

Population projection matrix (PPM) models are a central tool in ecology and evolution. They are widely used for devising population management practises for conservation, pest control, and harvesting. They are frequently employed in comparative analyses that seek to explain demographic patterns in natural populations. They are also a key tool in calculating measures of fitness for evolutionary studies. Yet, demographic analyses using projection matrices have, in some ways, failed to keep up with prevailing ecological paradigms. A common focus on long-term and equilibrium dynamics when analysing projection matrix models fits better with the outmoded view of ecosystems as stable and immutable. The more current view of ecosystems as dynamic and subject to constant extrinsic disturbances has bred new theoretical advances in the study of short-term "transient" dynamics. Transient dynamics can be very different to long-term trends, and given that ecological studies are often conducted over short timescales, they may be more relevant to research. This thesis focuses on the study of transient dynamics using population projection matrix models. The first section presents theoretical, methodological and computational advances in the study of transient dynamics. These are designed to enhance the predictive power of models, whilst keeping data requirements to a minimum, and borrow from the fields of engineering and systems control. Case studies in this section provide support for consideration of transient dynamics in population management. The second section applies some of these new methods to answer pertinent questions surrounding the ecology and evolution of transient dynamics in plants. Results show that transient dynamics exhibit patterns according to life form and phylogenetic history. Evidence suggests that this can be linked to the stage-structuring of life cycles, which opens up the possibility for new avenues of research considering the evolution of transient dynamics in nature.

Studiens syfte var att undersöka vilken betydelse införandet av grannsamverkan har på antalet bostadsinbrott. Den försökte även besvara vilka typer av åtgärder inom grannsamverkan som används samt likheter och skillnader mellan dessa, kopplat till områden i Södermalms stadsdelsområde. Ett matchat urval skapades varpå data insamlades genom strukturerade intervjuer med ombudsmän för grannsamverkan. I resultatet framställdes hur nivåerna över bostadsinbrott såg ut fem år innan-, samt ett till fem år efter, grannsamverkan implementerats. Materialet analyserades genom komparativ analys, varpå slutsatserna drogs att åtgärder som främst används var skyltning, säkerhetsdörrar, god belysning, god kontakt med boende i området, koll när granne reser bort samt uppmärksamhet på misstänkta i området. Skillnader och likheter mellan använda åtgärder fanns, vilket gör att generella slutsatser kring skillnader och likheter inte går att dra då inga områden är identiska. Gällande införande av grannsamverkan och dess betydelse för bostadsinbrott är resultaten tvetydiga då det skiljer sig hos områdena. / The aim of this study was to examine if the introduction of neighborhood watch affects the number of burglary. The questions asked were; which types of methods of neighborhood watch were used, and what kind of differences there were between selected areas in Södermalm, Stockholm. We created a matched sample of areas and contacted mediators of neighborhood watch in these areas. We conducted a quantitative study using structured interviews and presented data per burglary rates in the areas five years before and one to five years after neighborhood watch was implemented. The results were analyzed by comparative analysis and concluded that common methods of neighborhood watch were e.g. signage, security doors, good contacts between neighbors and attention to suspects in the area. The differences between the methods used means that general conclusions about differences and similarities cannot be concluded. The impact of neighborhood watch differed, and the results were ambiguous.
