Software Design of A Task-level High Level Synthesis Method

Jian, Jia-Dau 07 September 2004 (has links)
Along with the development of VLSI technology and the trend of system-on-chip design, traditional high-level synthesis can not deal with relatively complexity of system-on-chip design. In order to achieve optimal resource allocation, meet its performance and power requirements, and reduce its design time, we need a high-level synthesis software dealing system-level behavior. In consideration of system complexity, we have proposed a high-level synthesis method that synthesis for the task-level grains in a system behavior. This method performs efficient task-level resource allocation, task binding and task scheduling to reach a system design that meets the low performance and power requirements with low implementation cost. We utilize simulated annealing technique to achieve its overall system optimization. We designed and implemented the software design of the task-level high-level synthesis method. In this research, the design consists of three modules: the initial synthesis module, the heuristic movement module and the performance evaluation module. We will use the software to carry out the experiments of the task-level high-level synthesis method on application systems to verify its capability in designing systematic chips.

Seasonal and secular variations of sea level with special reference to the Canadian Pacific Coast

Siebenhuener, Hajo Fritz Wilhelm January 1970 (has links)
In the first part of this thesis definitions of sea level are given and causes and effects of its seasonal and secular variations are briefly discussed. The second part deals with the numerical determination of these changes on the coast of British Columbia. Using raw tidal data in the form of monthly means of sea level, seasonal variations are determined as annual oscillations with mean amplitudes between 5 and 12 cm for seven stations on the B.C. coast. The investigation of secular variations is based on (raw) annual means of sea level. These variations are essentially represented by linear trends which are statistically significant at the stations VICTORIA, VANCOUVER, POINT ATKINSON and PRINCE RUPERT, where they indicate submergence. Assuming an eustatic rise of sea level at the rate of 1.0 mm/yr, the influence of land movement on submergence is estimated. For VICTORIA, a probable land uplift since 1909 and for VANCOUVER, POINT ATKINSON and PRINCE RUPERT a definite land subsidence since about 1943 is found. The rates of land subsidence range between 1 and 2 mm/yr. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate

Mzdové rozdíly dle vzdělání a velikosti měst na příkladu Číny / Wage Differentials by Education and City Size: Evidence from Chinese Cities

Guo, Se January 2022 (has links)
This thesis uses CFPS's 2014 and 2016 data, from the perspective of differences in education levels and city size, using the two-way fixed-effect model and quantile regression to explore how the different educational workers' nominal monthly income gap changes with the expansion of the urban population. As for city size, on average, for every 1% increase in city size, the nominal monthly income of workers will increase by 0.4%. For every 1% increase in the size of the city, the nominal monthly wage of the college education group will increase by 0.9%, and the wage of the postgraduate workers will increase almost by 1.2%. The results show that only workers with a college and postgraduate education level can expand the monthly income gap with the lowest educational level group as the urban population grows. However, the nominal monthly income gap between the high-school educated group and junior high school and below educated workers is insignificantly affected by the city's expansion.

From Moral Psychology to Methods Morale: How Studying Moral Obligation Turned into a Duty to Study Methods

McManus, Ryan M. January 2023 (has links)
Thesis advisor: Liane Young / Thesis advisor: Hiram Brownell / When (moral) psychologists make a claim (e.g., “Participants judged X as morally worse than Y”), how many participants are represented? Such claims are often based exclusively on group-level analyses; here, psychologists often fail to report, or perhaps even investigate, how many participants judged X as morally worse than Y. More troubling, group-level analyses do not necessarily generalize to the person-level. This dissertation first investigates a moral cognition hypothesis about the relation between perceptions of relationship obligations and moral evaluations of helping behavior. It is found that people, on average, judge agents who help strangers as more morally good than agents who help family members, but people also judge agents who help strangers instead of family members as less morally good than agents who help family members instead of strangers. Second, methodological issues with these studies are assessed, fixed, and thus the original psychological effect is retested with better experimental designs, measures, and analyses. Third, it is discovered that the moral cognition hypothesis consistently describes the psychology of only a minority of participants. Moreover, it is discovered that most psychologists misinterpret typical group-level analyses as revealing how prevalent a psychological phenomenon is. Finally, a set of simple and flexible methodological and statistical options are offered to better align typical psychological hypotheses with appropriate analyses, enabling researchers to confront this “group-to-person generalizability” problem in their own work. / Thesis (PhD) — Boston College, 2023. / Submitted to: Boston College.

Evolutionary palaeobiology of deep-water conodonts

Smith, Caroline J. January 1999 (has links)
This study describes the conodont palaeontology of Upper Ordovician sections in Avalonia and Baltica. 24 species from 17 genera are systematically described and are attributed to the North Atlantic Realm. Sections can be correlated using graptolites and conodonts. The taxa are typical of the accepted Aphelognathus to Periodon shallow to deep-water biofacies. From the late Caradoc in Avalonia and Baltica, the Amorphognathus and deeper-water biofacies persisted in shelf settings. The stability of this distribution through the Ashgill, a period when Avalonia and Baltica drifted towards sub-tropical latitudes, suggests ocean cooling associated with glaciation was the dominant control on biofacies.Microfacies analysis of the phosphatic Amorphognathus superbus Biozone limestones from the Nod Glas Formation of the Welsh Borders indicates the presence of the oxygen minimum zone. Biofacies distribution in this section reflects the subtle variations in temperature within this unique habitat. A hypothesis is presented for the evolution of Amorphognathus ordovicicus in which range expansion into slope settings enabled parapatric speciation. Amorphognathus ordovicicus evolved gradually from a deeper water ancestor by the loss of the lateral process and cusp adjacent denticles on the M element. The initial and subsequent transgressions of the Ashgill brought Amorphognathus ordovicicus, and its cool water niche, into shelf areas. Gradual evolution in deep-water is predicted by the Plus ça Change model. The crown enamel of Periodon, Protopanderodus and Drepanodus records seasonally entrained growth with periods of refractional growth followed by longer functional episodes. Periodon exhibits reduced growth and comparatively short growth duration. Drepanodus and Protopanderodus show continued growth. It is hypothesised that Periodon was nektobenthic and adapted to harsh but stable conditions in the deep-sea, an r-strategist. Drepanodus and Protopanderodus were nektonic and grew to a large size indicating that they were AT-strategists. Upper Ordovician North Atlantic Realm nektobenthic conodonts were characterised by a high diversity and abundance of small sized individuals compared with coeval shelf faunas, a situation analogous to the modem oceans.
