浅论服装廓形的设计

服装外轮廓原意是影像、剪影、侧影、轮廓，在服装设计上引申为外形、外廓线、大形、廓型等意思。服装外轮廓是一种单一的色彩形态，人眼在没有看清款式细节以前首先感觉到服装的外轮廓。服装廓型是服装整体外形。形状广泛，种类丰富。不同的服装廓型。预示着服装的流行趋势。在掌握其廓型设计元素的同时，对不同的廓型进行合理搭配组合，可提高服装的品质和竞争力。     

Model-based testing with UML applied to a roaming algorithm for Bluetooth devices

In late 2001,the Object Management Group issued a Request for Proposal to develop a testing profile for UML2.0. In June 2003,the work on the UML 2.0 Testing Profile was finally adopted by the OMG. Since March 2004,it has become an official standard of the OMG. The UML 2.0 Testing Profile provides support for UML based model-driven testing. This paper introduces a methodology on how to use the testing profile in order to modify and extend an existing UML design model for test issues. The application of the methodology will be explained by applying it to an existing UML Model for a Bluetooth device.     

A fast block-matching algorithm based on variable shape search

INTRODUCTION Block-matching motion estimation is a key video coding technology that reduces the temporal redundancy between adjacent frames. The 3GPP/ 3GPP2 mandatory video codecs (MPEG-4 Simple Profile or H.263 Baseline) have adopted this tech- nology extensively. However, block-matching motion estimation is quite computationally intensive if the Full Search (FS) algorithm is used which exhaus- tively checks all possible candidate motion vectors within the search window. Therefore…     

Session - 5 December 18, 2007 AACC Symposium

The prevalence of abnormal thyroid hormone levels in diabetes mellitus in Nigeria is not well described. To determine the incidence of abnormal thyroid hormone levels in diabetics in Calabar, Nigeria, fasting blood samples from 161 diabetic subjects and 105 non-diabetic controls were analysed. Free thyroxine (FT), thyroid stimulating hormone (TSH), total triiodothyronine (T₃) and total thyroxine (T₄) kits obtained from Biomerica Inc. of USA were used for the analysis. TSH levels (1.80±1.62) in diabetics were significantly lower (p=0.016) than the level in non-diabetic controls (2.34±1.24). Male diabetics had lower (p<0.05) levels of TSH (1.192±0.68 miu/ml) than diabetic females (1.90±1.70 mlu/mt). The level of T₃ in diabetic males (125±97ng/ml) was higher than the level in females (98±75ng/dl). TSH (F=2.74, p=0.049), T₄(F=56.87, p=0.001), T₃(F=56.44, P=0.001) in diabetics and FT₄ (F=5.74, p=0.002) in controls showed significant variation with the ages of the subjects. Out of 161 diabetics subjects studies 26.6% had low plasma thyroid hormone levels (FT₄>2.01 ng/dl). This study has shown a high incidence (46.5%) of abnormal thyroid hormone levels among the diabetics in Nigeria (hypothyroidism 26.6%, hyperthyroidism, 19.9%). The prevalence of hypothyroidism was higher in women (16.8%) than in men (9.9%), while hyperthyroidism was higher in males (11%) than in females (8%). This study has defined thyroid function status of diabetics in Calabar, Nigeria probably the first of such work in Africa.     

混合学习环境下学习者的在线自我调节学习潜在剖面分析及行为过程挖掘

混合学习强调线下课堂教学和线上自主学习的混合以实现优势互补,其中学习者的在线自我调节学习能力显得异常重要。文章旨在揭示学习者的在线自我调节学习能力存在哪些潜在类别,不同类别学习者是否具有不同的在线自我调节学习行为过程模型,以及这对于在线自我调节学习环境的设计有何启示。研究首先对239名学习者的在线自我调节学习能力进行测评,然后使用潜在剖面分析方法对测评数据进行分析,发现样本学习者可以分为高、中、低三种不同水平的自我调节学习剖面类别。然后分别对三种类别学习者的在线自我调节学习行为数据进行过程挖掘,研究发现:(1)学习者的自我调节学习能力更多体现在执行阶段的行为上;(2)中高水平自我调节学习者的在线学习行为表现出更强的认知和元认知策略;(3)高水平自我调节学习者体现出更有效的时间管理策略与更强的整体规划能力。因此,在线自我调节学习环境需要引入自适应支持机制,为学习者提供适应性的过程和策略支持。     

Thyroid hormone profile in peritransplant period in live donor kidney transplantation

Chronic renal failure, characterised by two factors acting in opposite directions with respect to the serum thyroid homone levels was chosen for the study. Healthy controls, donors undergoing nephrectomy and renal transplant recipients were studied. In transplant recipients, presurgical levels of total thyroxine(TT4), free triiodothyronine(FT3) and free thyroxine(FT4) were lower than controls, and immediately after the release of arterial clamps, there was an upsurge of total triiodothyronine (TT3), TT4, FT3 and FT4 due to administered and/or endogeneously secreted catecholamines. The levels of the 7th day were comparable to the presurgical levels. The changes observed in donors and recipients were similar indicating that the hormonal changes observed are mostly due to surgical stress. Recovery in the hormonal status did not start in the first week of posttransplant period.     

利用Surfer提取剖面的物理场值技术研究

针对Surfer软件中剖面的物理场值提取时产生的数据冗余,提出利用高级程序设计语言来编制程序剔除这些冗余数据,从而实现剖面的物理场值的精确提取,并通过试验验证了这种技术的效果。     

Altered maternal thyroid function: Effect of L-carnitine supplementation on fetal and neonatal myocardial free fatty acid oxidation,in vitro

Effect of L-carnitine supplementation on myocardial free fatty acid oxidation,in vitro, in offsprings born of hypothyroid and hyperthyroid mothers was studied in rats. L-carnitine supplementation stimulated myocardial fatty acid oxidation during gestational period in offspring born of control and hyperthyroid mothers. In contrast L-carnitine supplementation induced stimulation in myocardial fatty acid oxidation was very less in fetuses born of hypothyroid mothers. However, in neonates born of hypothyroid mothers L-carnitine stimulated myocardial fatty acid oxidation to a great extent. The results suggested that during maternal hypothyroidism low availability of thyroid hormones to fetuses through maternal circulation and availability of less carnitine to neonates due to hypolactation might be responsible for decreased myocardial free fatty acid utilization. In neonates born of hypothyroid mothers and with cardiac energy insufficiency parenteral carnitine supplementation might be of great help to prevent mortality and morbidity of such offsprings.
