Non-metric skeletal variation in Neolithic Hunter-Gatherers of the Cis-Baikal, Siberia

Macintosh, Alison 12 April 2011
Postcranial non-metric skeletal traits are documented in two Cis-Baikal populations: the Kitoi, dating to the Early Neolithic (8000-7000/6800 BP), and the Isakovo/Serovo/Glazkovo (ISG) cultural complex, dating to the Late Neolithic (Isakavo/Serovo: 6000/5800-5200 BP) and Early Bronze Age (Glazkovo: 5200/5000-4000 BP). A major cultural discontinuity is thought to have occurred in the Middle Neolithic (7000/6800-6000/5800 BP). Current and previous research suggests that the Early Neolithic Kitoi were bioculturally distinct from the Late Neolithic-Bronze Age ISG cultural complex. Population, side, sex, and age differences in the expression of non-metric traits were explored as indicators of differing activity patterns and divisions of labour between and within the Kitoi and ISG samples, as well as two Kitoi cemeteries: Shamanka II and Lokomotiv. Results of analyses indicate that the Kitoi, particularly males, were taking part in locomotion over steep terrain while carrying heavy loads, probably related to hunting trips. The ISG do not show evidence of these types of activities, suggesting a population difference in the frequency and degree of physically strenuous activity. Kitoi and Shamanka II males and young adult individuals show evidence of having performed the majority of the strenuous lifting and carrying, as well as evidence of increased mobility relative to females. These results indicative of strong divisions of labour in the Kitoi population. Patterns in trait frequencies were also examined for indications of how multiple underlying factors may be interacting. Trait distribution throughout the body provides evidence of the dominance of biomechanical stress as a causative factor in the expression of postcranial non-metric traits. Other factors that become visible when the influence of biomechanical stress is lower include genotype, trauma, and cartilage degeneration. The results of this project are consistent with current theories on the adaptive regimes of the Kitoi and ISG populations and strongly support previous work by BAP researchers in the areas of skeletal robusticity, osteoarthritis, and musculoskeletal stress markers. The research also helps to broaden the knowledge base about the etiologies of the non-metric traits involved.

Evaluation of Service Composition Methods: Using Government Lands Integrated System as an example

Yu, Tao-Kang 05 February 2012 (has links)
As time and technology evolves, the applications of cloud computing increase in our daily life. SaaS enterprise applications also increase in business context. The success of the information systems in the cloud era relies on the proper selection and combination of Web Services. This is especially true for complex business processes, which often require effective and efficient way to reuse existing functions. Following the study in (Li Jianxiang, 2011), which proposes the model of General Service Pattern, we aim to evaluate the General Service Pattern model using real processes in land administration. The evaluation metrics include time and correctness. The study shows that the use of General Service Pattern significantly shorten the time required to construct land administration processes, when compared to the design from scratch and the design by providing similar processes. . The correctness of the yielded processes is also higher than the other two methods. We therefore conclude that General Process Pattern is a promising model.

Research on Robust Control of Micromachined Accelerometers

Wu, Wei-ming 22 August 2000 (has links)
This paper presents the research on the robust control of micromachined accelerometers. First, we present different micromaching techniques and compare, analyze the accelerometers with different methods of signal pick-off. Besides the different methods of signal pick-off(the position detection of the seismic mass) and structure designs, we can enhance the performance such as stability, bandwidth, sensitivity, resolution and dynamic range etc. by suitable feedback controllers. So inside the front part of the paper are the analyses for the controllers of different types of accelerometers so far. Moreover, we design the controllers by robust control in different methods with the model of one specific type of micromachined tunneling accelerometer. Because of the robust controllers, the accelerometers can be stable and have good performance under different environments and uncertainties. At last we analyze and compare the controllers designed by -synthesis and gap metric.

The Influence of Growth and Development in the Expression of Human Morphological Variation

Wood, Carolan 16 December 2013 (has links)
This analysis examined cranial epigenetic and morphological nonmetric traits in 756 subadults (fetal to <20 years), in European, African, and Asian samples. The goals of this research were to assess: the age and manner in which nonmetric traits develop and if variation between geographic groupings is present in subadults; the role of the adolescent growth spurt in trait expression; the feasibility of utilizing subadult crania in biological distance studies and ancestry assessment. A number of epigenetic and morphological traits show a primarily genetic versus developmental basis, suggested by the fact that there was no difference in trait frequencies between the fetal/0-3 and 15-20 year age categories. Eighty-five percent of epigenetic traits appear before 3 years; 54% were age stable by 3 years, and 75% were stable before age ten. Geographic cranial variation is present at an early age as demonstrated by the appearance of 58% of morphological traits before age 3, and 90% by age 10. Ten and a half percent of morphological traits are age stable before 3 years of age, 48% by age 10. Traits statistically significant between pre-pubertal and pubertal and/or pubertal and post pubertal individuals are hyperostotic, functional, and in some cases, sex dependent. Few epigenetic (1.3%) and morphological traits (7.9%) were found to be sex dependent, possibly because sexually dimorphism may not be fully expressed in individuals in the 15-20 year age category. Features that indicate ancestry develop before puberty, and do not require the onset of puberty and sexual dimorphism to be fully formed. Three-quarters of epigenetic traits were age stable and showed trait frequencies similar to adults before 10 years of age, suggesting subadults could be included in biodistance studies using these traits. Twenty-four morphological traits were statistically significant between geographic groups and show promise for future use in the forensic analysis of ancestry assessment in children.
