This thesis contains analysis of currently available Objective-C run-time libraries (GCC, Apple and Étoilé run-times), their prerequisites and dependencies on the particular platform and operating system. The result of the analysis is a design of a modular run-time library that allows dynamic configuration of each component for the particular need (e.g. disabling run-time locks in a single-threaded environment). The resulting design can also be easily ported to other atypical platforms (e.g. kernel, or an experimental OS) and extended feature-wise (e.g. adding support for Objective-C categories, or associated objects). A prototype implementation of such a modular run-time for Objective-C also is included.

Current parallelizing compilers cannot identify a significant fraction of parallelizable loops because they have complex or statically insufficiently defined access patterns. In our previous work, we have speculatively executed a loop as a doall, and applied a fully parallel data dependence test to determine if it had any cross–processor depen- dences. If the test failed, then the loop was re–executed serially. While this method exploits doall parallelism well, it can cause slowdowns for loops with even one cross- processor flow dependence because we have to re-execute sequentially. Moreover, the existing, partial parallelism of loops is not exploited. We demonstrate a generalization of the speculative doall parallelization tech- nique, called the Recursive LRPD test, that can extract and exploit the maximum available parallelism of any loop and that limits potential slowdowns to the over- head of the run-time dependence test itself. In this thesis, we have presented the base algorithm and an analysis of the different heuristics for its practical applica- tion. To reduce the run-time overhead of the Recursive LRPD test, we have im- plemented on-demand checkpointing and commit, more efficient data dependence analysis and shadow structures, and feedback-guided load balancing. We obtained scalable speedups for loops from Track, Spice, and FMA3D that were not paralleliz- able by previous speculative parallelization methods.

It is important to estimate the quantity of wave run-up and overtopping in seawall design. Previous study on the investigations of run-up is carried out mostly in the laboratories, it seldom perform in field measurements. About previous wave run-up equation can¡¦t accurately estimate run-up elevation. According to run-up data, this study hope that it can make the formula to meet the actual local situation. It can have a better reference by designing coastal structures. This paper study wave run-up during five typhoons by Kalmaegi ,Fung-Wong,Nuri, Hagupit,and Jangmi. It measuring wave height , water level,and topography. These data show that the run-up elevation in bay higher than in breakwater. It shows that wave pass through a submerged breakwater can decay wave height. Analysis of measured data and found that when the wave height is about 1~4 meter with 1/(H0/L0)0.5 has a good correlation. It similar to some past researchers. Experience equations close to measured value when wave height smaller than 4 meter. When wave height more than 4 meter, the empirical prediction value is larger than measured value. Wave run-up doesn¡¦t have good theory, and experience equations different about every field. The empirical equations depends on the scene to investigate the effects of various parameter.

This study examined the acute and chronic effects of changes in training volume and intensity on the blood lymphocyte percentages and immunoglobulin levels in runners. Twelve runners participated in four 10-day phases over a 40 day training period. Phase 1 and phase 3 were "baseline" phases of low volume/low intensity running (LV/LI). Phase 2 and phase 4 consisted of either high volume/low intensity (HV/LI) or high volume/high intensity (HV/HI) training. Subjects were randomly assigned to one of 2 different crossover training group orders: 1) LV/LI, HV/LI, LV/LI, HV/HI or 2) LV/LI, HV/HI, LV/LI, HV/LI. HV/LI training involved doubling the LV distance run at the same LI of 60-70% V02 max. The HV/HI phase consisted of the same volume as the HV/LI phase, but alternate days were replaced with a series of high intensity 1000 m intervals (95-100% V02 max). Venous blood samples were drawn at rest on days 1, 4 and 7 and 5 minutes post-exercise on days 1 and 7 of each 10-day phase. Lymphocyte subsets were determined by flow cytometry using monoclonal antibodies for total T (CD3+), T-helper (CD4+), T-suppressor (CDS+) lymphocytes and HLA-DR+ (a B cell and "activated" T-lymphoid cell marker). IgA, IgG and IgM levels were obtained by ELISA analysis. This study revealed remarkable stability of humoral (antibody) immune components during and after runs of various intensities and volumes. Immunoglobulin levels were not significantly affected by alterations in volume or intensity over the 4 training phases. A transient decrease was observed in the T-lymphocyte percentages of CD3+, CD4+ and the CD4/CD8 ratio 5 minutes post-exercise which was significant (p <.05) during the HV/LI and HV/HI phases. Adaptation of lymphocyte subpopulations occurred with repeated exposure to increases in volume and intensity. A training order effect was suggested whereby an initial HI phase, was more immunosuppressive and possibly negated the effects of subsequent HV phases. Results indicate that the exercise-induced lymphocyte subset reduction is transient and suggest that the extent of the reduction is more dependent upon training intensity than volume, and the order of exposure to the high-intensity stimulus may determine the magnitude of subsequent responses. / Thesis / Master of Science (MSc)

5 pp. / Urban run-off is created by rain, snowmelt, or irrigation water flowing across sidewalks, drive ways, roadways, and other surfaces into storm drains. All storm drains empty into rivers or river beds, lakes, streams, washes, and other storage areas often without treatment. The Urban Run-off (Non-point Source Pollution) Tip Sheet will educate the reader on urban run-off and associated water pollution. The tip sheet explains the causes, effects, and sources of non-point source pollution. It also provides information on what can be done to prevent urban run-off and water pollution. It includes both general information as well as information specific to Maricopa County.
