Development of a Weight Control System for Ship ConstructionTsao, Jui-lin 24 June 2005 (has links)
It is a vitally important task to achieve control of the weight and center of gravity of lightship during building a new ship. If the lightship weight is slightly out of control, the deadweight inadequacy and a deviation from the initial design target will be caused. The basic performance and function of a ship at sea are also resulted. Furthermore, if the lightship weight is incompletely under control, it will bring about an unsafe vessel, ship-delivery difficulty and a severe loss for shipbuilder.
Docking arrangement is optimized to allocate by using the state-of-the-art finite element method to analyze the lightweight distribution as the load and the ship girder as a beam; in addition, the dock is recognized as a spring-liked elastic foundation subjected to compression only. It is verified by comparison between measurement of the lightship weight by means of the weight control system on land and the traditional inclining experiment. Based on the results, it can be shown that the whole system is reliable, available and efficient.
The load cell is utilized as a component of the weight control system to measure the compressive force (i.e., ship weight) at a specified dock. The main function of the system is to determine the lightweight and its C.G. on-land construction instead of the time-consuming and labor-wasting traditional way. The presented methodology will be beneficial for weight control of a new-ship building in the future.

A-最適試驗處理與對照處理比較之Diallel Crosses實驗 / Families of A-Optimal Diallel Crosses for Test versus Control Comparisons徐永豐, Hsu, Yung-Feng Unknown Date (has links)
Diallel cross experiments for comparing p test lines with a control in the set up of block designs and completely randomized designs are investigated. Complete diallel crosses including all p(p+1)/2 distinct crosses are considered. Families of A-optimal and efficient type S0 block designs for p=2,3, and for p>=4, k=2 are obtained, and the construction methods are given. For p>=k>=3, and p>=4, a sufficient condition for type S0 block designs with the control line appearing tb times, where t>=1 is an integer, to be A-optimal is obtained, and families of A-optimal type S0 block designs are provided. The A-optimality of type S designs under the model of completely randomized designs when 2<=p<=6 is also tudied, and some examples are given.

Minimal Sufficient Statistics for Incomplete Block Designs With Interaction Under an Eisenhart Model IIIKapadia, C. H., Kvanli, Alan H., Lee, Kwan R. 01 January 1988 (has links)
The purpose of this paper is to derive minimal sufficient statistics for the balanced incomplete block design and the group divisible partially balanced incomplete block design when the Eisenhart Model III (mixed model) is assumed. The results are identical to Hultquist and Graybill's (1965) and Hirotsu's (1965) for the same model without interaction, except for the addition of a statistic, ∑ijY2ij•.

Neuromuscular fatigue in people with chronic strokeSignal, Nada E. J. Unknown Date (has links)
The aim of this study was to examine and compare the contribution of central neuromuscular fatigue and peripheral neuromuscular fatigue to total neuromuscular fatigue in the hemiplegic leg of people with stroke, with that of a matched control group.Study Design: This experimental study utilised a repeated measures block design.Participants: Fifteen people with chronic stroke who had mild to moderate physical disability and fifteen age, height and weight matched controls were compared.Main outcome measures: Participants physical function was evaluated using the 30s Chair Stand Test, Comfortable Paced Walking Speed and Fast Paced Walking Speed. Neuromuscular function was measured using maximal voluntary isometric contraction force and voluntary activation. Total neuromuscular fatigue, central neuromuscular fatigue and peripheral neuromuscular fatigue was measured during a 90 second sustained maximal voluntary isometric contraction of the quadriceps muscle.Results: The fatigue profile of stroke participants differed from that of control participants. Stroke participants demonstrated less total neuromuscular fatigue (U=41.00, p=.026) and less peripheral neuromuscular fatigue (U=14.00, p=.000) than the control participants. While stroke participants did demonstrate greater central neuromuscular fatigue than control participants, this finding was not statistically significant (U=80.00, p=.817).Conclusions: Statistically significant differences were found in the performance of people with mild to moderate physical disability following stroke on measures of neuromuscular fatigue when compared to age, weight and height matched healthy adults.

Automorphic Decompositions of GraphsBeeler, Robert A., Jamison, Robert E. 01 March 2011 (has links)
A decomposition D of a graph H by a graph G is a partition of the edge set of H such that the subgraph induced by the edges in each part of the partition is isomorphic to G. The intersection graph I (D)of the decomposition D has a vertex for each part of the partition and two parts A and B are adjacent iff they share a common node in H. If I (D) ≅ H, then D is an automorphic decomposition of H. In this paper we show how automorphic decompositions serve as a common generalization of configurations from geometry and graceful labelings on graphs. We will give several examples of automorphic decompositions as well as necessary conditions for their existence.

Robust designs for field experiments with blocksMann, Rena Kaur 28 July 2011 (has links)
This thesis focuses on the design of field experiments with blocks to study treatment effects for a number of treatments. Small field plots are available but located in several blocks and each plot is assigned to a treatment in the experiment. Due to spatial correlation among the plots, the allocation of the treatments to plots has influence on the analysis of the treatment effects. When the spatial correlation is known, optimal allocations (designs) of the treatments to plots have been studied in the literature. However, the spatial correlation is usually unknown in practice, so we propose a robust criterion to study optimal designs of the treatments to plots. Neighbourhoods of correlation structures are introduced and a modified generalized least squares estimator is discussed. A simulated annealing algorithm is implemented to compute optimal/robust designs. Various results are obtained for different experimental settings. Some theoretical results are also proved in the thesis. / Graduate

Evaluating the Efficacy of Relational Training Procedures to Increase IQ On The Block Design SubtestRohail, Mina 01 May 2018 (has links)
The purpose of the current investigation is to two-fold: 1) to determine whether relational training increases block design and IQ score 2) to determine if relational training results in increased performance on block design programs. The Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) for Children intelligence assessment was assessed to the participant prior to baseline and after training, and programs adapted from the PEAK-Relational Training System were used for relational training procedures. A multiple-baseline design across skills (relational frames) design was used in the present study. Test relations (Y-Z) were probed during training after 3 training trial blocks and novel stimuli were used. The results indicate that the relational procedures were effective in increasing IQ on the block design subtest. The implications of the current study are discussed.
