Multi Sub-Pass & Multi Render-Target Shading In Vulkan : Performance Based Comparison In Real-time

Danliden, Alexander, Cederrand, Steven January 2020 (has links)
Background. Games today are becoming more complex in computational andgraphical areas. Companies today want to develop games with state of the artgraphics while also having complicated and complex game logic. The vast majorityof users rarely meet the computer requirements. This creates an issue which lim-its the target demographic that a company wants to meet. This thesis will focuson two different methods that achieves deferred shading in Vulkan and how the en-vironment is affecting both methods as-well as the number of lights and attachments. Objectives. In Vulkan there are two ways of implementing deferred shading, one isthe traditional way of doing it which is by conducting multiple render-targets. Thesecond way is by utilizing a feature unique to Vulkan known as sub-passes. Our aimis to conduct experiments with these two ways of implementing deferred shading todetermine which one is the most optimal for a given situation. These situations willvary depending on the number of visible objects and number of lights in the scene. Methods. The experiments are conducted by a rendering system that have beenimplemented by us. By implementing both suggested deviations of the renderingtechnique ’deferred shading’ the data collected will suffer less from unexpected andunknown variables than it would if the implementations were taken from a separatesource. The experiments that will be conducted intend to measure performance met-rics in the form of average frames per second as well as average render frame time(inseconds). To measure the time performance metric, the system shall utilize Vulkan’ssupport for gpu-timestamping[7]. To provide reliable measurements without any un-warranted errors each rendering deviation will utilize pre-recorded command buffers. Conclusions. This thesis has shown that using multiple sub-passes within a singlerender-target performs faster write operations to the attached render attachments.This result in less memory bandwidth which leads to a faster geometry pass. Theperformance gain from a faster geometry pass can be used somewhere else to en-hance different aspects of the game or graphical application. Having less memorybandwidth would result in a longer battery life on mobile phones and laptops.

Vliv modifikovaných her na kvantitu herních kombinací u florbalistů mladšího školního věku / Influence of modified games on the quantity of game combinations of primary school age floorball players

Míka, Ondřej January 2021 (has links)
Title: Influence of modified games on the quantity of game combinations of primary school age floorball players Objectives: The aim of this work was to find out the effect of prepared training programme on quantity of passing, team cooperation and quantity of shots. The research was aimed on passing accuracy (passing quality) after ball carrying, quantity of passes in training match on smaller pitch. The number of the players was 3 on 3 there. It was also aimed on quantity of passes in league match on standard pitch. There were 5 players against 5. At the end of the training programme, we made revisory tests to assess a positive effect of the programme. Methods: We used a method of an experiment. At first, there were preliminary tests before an adjusted training program so that we got input data. Then we applied adjusted training programme and then there were another control tests to get output data. The programme included both modified games and game-like drills. During the tests, we used participant observation. Results: The results showed an increase of quantity in all tests. But only in passing accuracy after ball carrying test and in quantity of passes in league match the results were statistically significant. The other test showed no statistical significance. Keywords: game, modification,...

Throughput of UWC students who did at least one semester of third-year Statistics

Latief, Abduraghiem January 2005 (has links)
>Magister Scientiae - MSc / The study explores the completion rates (the number of years a student takes to complete a degree) of graduates at the University of the Western Cape (UWC) in South Africa. The graduates in the study all did at least one semester of statistics in their final year of study. The students' completion will be described with respect to school results and socio-demographics. Differences between students who finished their studies in the prescribed time of three years and those who took longer than the prescribed time will be highlighted. Factors that aid or hinder students from successfully completing their studies in the prescribed time will be analyzed. An entry selection model will be developed to screen the students. This will assist with an enrolment strategy. The most significant result found was that the political environment played the most significant role in throughput. The next significant result from the study showed that the grade 12 aggregate played a significant role in throughput. It is suggested that UWC be proactive in developing alternative methods of selecting students, since the new Further Education Training (FET) school system, which will be implemented in 2006, will omit the grade 12 aggregate.

Intestinal Transport as a Potential Determinant of Drug Bioavailability

Nauli, Andromeda M., Nauli, Surya M. 01 January 2013 (has links)
Orally administered drugs are generally absorbed by the small intestine and transported either to the lymphatic system or to the hepatic portal system. In general, lipid soluble drugs and vitamins are transported by the small intestine to the lymphatics, and water-soluble drugs are transported to the hepatic portal system. By avoiding the early hepatic first pass effect, the lymphatic transport system may increase drug bioavailability. In addition to its transport systems, the small intestine may affect drug bioavailability through drug uptake, intestinal first pass effect, recruitment of drugs by chylomicrons, formation and secretion of chylomicrons, and enterohepatic circulation. All of these factors should be considered when formulating orally administered lipophilic drugs. Our data also suggest that Caco-2 cells may serve as a valuable in vitro model to study the intestinal transport of orally administered drugs.

Non-Nursing Courses' Impact on NCLEX-RN Pass-Rates in Associate Degree Nursing Programs

Garner, Nicole A. 01 January 2018 (has links)
Nurse educators make decisions regarding the inclusion or exclusion of non-nursing courses in a curriculum. The current literature lacks research regarding which courses have the most impact on first-time nursing licensing examination pass-rates. The purpose of this quasi-experimental study was to investigate if there is a specific combination of courses that enhance first-time licensing examination pass-rates, using 161 randomly selected accredited associate degree nursing programs. General systems theory applied to nursing education was the framework for the study. ANOVA and independent t-tests were used to address the questions of non-nursing courses or discipline-specific set of non-nursing courses' impact on first-time licensure pass-rates. The ANOVA and independent t-tests analyses did not yield any significant non-nursing courses or discipline-specific sets of non-nursing courses. The findings indicate that non-nursing courses are not a significant subsystem in nursing education when the sole outcome used is NCLEX-RN pass-rates. Nursing faculty can use the results of this study as evidence that the inclusion or exclusion of one non-nursing course over another will likely not be detrimental to their program. This study can lead to positive social change through increasing the evidence-based knowledge from which faculty can base their curriculum.

Examination of Deformation in Crystalline Rock From Strike-Slip Faults in Two Locations, Southern California

Forand, David H. 01 May 2010 (has links)
Damage zones adjacent to or associated with faults are important to the geologic community because of their implications to hazards and their ability to preserve evidence for, and show history of, slip, fluid flow, and deformation associated with large strike-slip faults. We examine two fault zones in southern California where fault zone damage is expressed. We revisit the drilled crystalline core from the Cajon Pass California drill hole, 4 km northeast of the San Andreas fault (SAF), and 1 km north of the Cleghorn fault, to perform a systematic structural analysis of deformation and alteration associated with strike-slip faulting at the site. The core preserved 19 fault zones, 11 of which were not previously identified. The most significant fault is a fully intact steep-dipping fault zone at 3,402 m depth with potassium feldspar and epidote alteration. This fault correlates well with the nearby left-lateral Cleghorn fault. The extent of deformation varies within the core, and is controlled by the size of the fault zones intersected by the core. The extent of deformation varies and is controlled by the size of the faults the core intersected. We also examined the nature of right separation across the Clark fault damage zone along the Santa Rosa segment using a marker assemblage of biotite, hornblende-bearing tonalite - marble - bearing metasedimentary rocks - migmatite located in Coyote Mountain and the southeast Santa Rosa Mountains. Separation measured from this study is 16.8 km + 3.67 km / -6.03 km. Our measurement uses the updated location of the Clark fault in Clark Lake Valley and matches a distinctive lithologic contact across the fault instead of matching the diffuse western boundary of the Eastern Peninsular mylonite zone as previously used. We calculate the errors associated with projecting the contacts across Quaternary cover to the trace of the Clark fault, and consider a range of projections. Additional strain may have been accommodated in folds and small faults within the damage zone of the San Jacinto fault zone. Two large map-scale folds deform the marker assemblage near the San Jacinto fault zone and we tested whether Cretaceous ductile deformation or brittle late Quaternary right slip produced the folds.

Evaluation of Nature-like and Technical Fish Passes for the Passage of Alewife (Alosa pseudoharengus) at Two Coastal Streams in New England

Franklin, Abigail 01 January 2009 (has links) (PDF)
Nature-like fish passes have been designed with the intent to re-connect river corridors and provide passage for all species occurring in a system. Nature-like fish pass designs have been constructed in Europe and elsewhere with some success, but performance of these designs has not been evaluated for North American species. Re-establishing passage for adult anadromous clupeids to their spawning areas is critical considering their recent dramatic population declines. Two nature-like fish pass designs in New England were evaluated for passage of anadromous adult alewives (Alosa pseudoharengus) using passive integrated transponder (PIT) telemetry and showed differing results. At Town Brook in Plymouth, Massachusetts the 32 m long perturbation boulder rock ramp with a 1:24 slope passed 94% of attempting fish with most ascending in under 22 minutes. At East River in Guilford, Connecticut the 48 m long steppool bypass design with a 1:14 slope passed only 40% of attempting fish with a median transit time of 75 minutes. Two technical fishway designs at the field sites were also evaluated and showed contrasting performance. At Town Brook a 14 m long 1:7 slope pool and weir fishway exhibited attraction and passage deficiencies. At East River two 3.05 m long steeppass fishways both passed the majority of attempting fish but one steeppass fishway may have had poor attraction efficiency. At both sites tagged fish passed rapidly downstream through the fish passes after spawning. Nature like fish pass designs are suitable for the passage of alewife but further evaluations are required to more precisely identify the influence of vertical drop per pool and specific local hydraulics on behaviors and passage performance for this species.
