Arvin Meritor Factory Brno
Vysoké učení technické v Brně. Fakulta stavební, 2018Co-Authors: Sergeeva AnnaAbstract:This bachelor's thesis discusses a solution of the new-build factory Arvin Meritor in Brno, where the neglected area of the former junkyard (registered as a brownfield number 1904) in Maloměřicí between Borky and Slaměníková streets is used. Determinating the area the transverse substance has been formed perpendicular to the surrounding embankments for minimum usage of the land and the maximum variability of the completion in the future. The basic shape of the building comes from the Reciprocal Displacement of the production lines and their connection to the glass corridors shaping the main production part. This principle gives an interesting altitude difference, also allowing the possibility of adding further units such as auxiliary factory operations and the input unit. These features are layered in a way to make the solution as flexible and universal as possible. The "input unit" is the dominant feature of the whole building, for that, a glass facade is used to create sufficient lighting for the administration. There is a construction with red facade lamellae mounted in front of the glass facade, which is used for highlighting and shading. Copilit and sandwich panels are used on the longitudinal facade of the production part, while strip windows are pulled through the entire length and create a contact of workers with the environment. Other parts of the building used tin sandwich grey shade panels, while the roof used sawtooth skylights turned to the northeast with 45 degrees angle corresponds to the building. Finally, a suggestion of backbone traffic is also discussed in this thesis in details

Arvin Meritor Factory Brno
Vysoké učení technické v Brně. Fakulta stavební, 2018Co-Authors: Sergeeva AnnaAbstract:Předmětem zadání bakalářské práce je řešení novostavby závodu Arvin Meritor v Brně kde byla využita zanedbaná plocha bývalého autovrakoviště v Maloměřicích mezi ulicemi Borky a Slaměníkovou, která je vedena jako brownfield č.1904. Vymezením pozemku byla vytvořena příčná hmota kolmo k okolným násypům pro minimální užití plochy pozemku a pro maximální variabilitu dostavby v budoucnu. Základní tvar budovy vychází z posunutí mezi sebou výrobních linek a jejich propojením skleněnými chodbami co vytváří hlavní výrobní část. Takový princip dává zajímavý výškový přepad a taky umožňuje přidání dalších celků: pomocných provozů a „vstupního celku“. Tyto funkce jsou vrstveny tak, aby řešení bylo co nejvíce flexibilní a univerzální. „Vstupní celek“ je dominantou celé budovy. Pro ně byla použita skleněná fasáda, což vytváří dostatečné osvětlení pro administrativu. Před ní je namontovaná konstrukce s červenými fasádními lamelami, která slouží jak pro zvýraznění, ta i pro stínění. Na podélné fasádě výrobní části použit copilit a sendvičové panely. Pásová okna jsou protáhnuté o celé délce a vytvářejí kontakt pracovníků s prostředím. Pro ostatní části budovy taky použité plechové sendvičové panely šedého odstínu. Na střeše jsou použité pilový světlíky, které jsou natočený do severovýchodní strany, a to je 45o vůči budově. Taky byla navřena páteřní objízdná komunikace.This bachelor's thesis discusses a solution of the new-build factory Arvin Meritor in Brno, where the neglected area of the former junkyard (registered as a brownfield number 1904) in Maloměřicí between Borky and Slaměníková streets is used.

Analysis on Arithmetic and Application of Rigidity Distribution for Simply Supported Structure
2013Co-Authors: Ling–bo Wang, Xin KangAbstract:Bridges under life–long service often suffered from invisible diseases which could cause the bridge stiffness decay (rigidity) and pose great threatening to human lives. This paper focused on studying the real stiffness distribution in a simple beam. The relationship between stiffness and deflection in a bridge segment has been established which is based on the material mechanics, numerical modeling, and Reciprocal Displacement theorem. The conversion of the deflection curve at mid span resulted from three axle vehicle and single unit load has been developed so that by measuring the deflection caused by low speed vehicle passing over the bridge, the real stiffness distribution of the bridge could then be obtained and the assessment of the bridge damage could be carried out. Compatible software was developed in accordance with the proposed stiffness calculation method. The software was found worked well in predicting the stiffness distribution and the test results supported that the proposed prediction method is applicable. The test results showed that the stiffness distribution in longitudinal direction varied significantly, which is due to the different degrees of damage. The analysis showed that it is not good to use the overall stiffness to evaluate the damage of the whole beam.

Stiffness Distribution Prediction in Simply Supported Structure and Its Application
Journal of Wuhan University of Technology, 2014Co-Authors: Wang Ling-bAbstract:Long service life highway bridges usually suffer from significant damages,such as concrete crack,rebar corrosion and pre-stressed rebar relaxation,which will in turn cause serious stiffness decay of bridge.This paper focused on figuring out the real stiffness distribution in simply supported beams.The material mechanics,numerical analysis,and Reciprocal-Displacement theorem were employed to deduced the stiffness distribution in each section of the beam.A conversion relationship of the deflection curve at mid-span between 3axles vehicle and the unit load was established so that by collecting the deflection time schedule curves at the mid span while vehicles move across the bridge at a lower speed,the real stiffness of the beam can be calculated and the assessment of the overall performance of the bridge was also obtained. A compatible software was developed to calculate the stiffness distribution automatically.A case study was conducted to verify the efficiency of the presented method.The experimental results show that the damage degree were different at different longitudinal sections.It is inappropriate to use the overall stiffness to evaluate the damage of the whole bridge.The analysis results match pretty well with the calculated stiffness distribution.Thus the proposed method can applicate in engineering practices,such as to predict the stiffness decay,detect the damage area and estimate the degree of damage.

Measurement of pulsatile flow using MRI and a Bayesian technique of probability analysis.
Magnetic resonance imaging, 1996Co-Authors: Richard G. Wise, Benedict Newling, A. R. C. Gates, Da Xing, T. A. Carpenter, Laurance D. HallAbstract:This work shows that complete spatial information of periodic pulsatile fluid flows can be rapidly obtained by Bayesian probability analysis of flow encoded magnetic resonance imaging data. These data were acquired as a set of two-dimensional images (complete two-dimensional sampling of k-space or Reciprocal position space) but with a sparse (six point) and nonuniform sampling of q-space or Reciprocal Displacement space. This approach enables more precise calculation of fluid velocity to be achieved than by conventional two q-sample phase encoding of velocities, without the significant time disadvantage associated with the complete flow measurement required for Fourier velocity imaging. For experimental comparison with the Bayesian analysis applied to nonuniformly sampled q-space data, a Fourier velocity imaging technique was used with one-dimensional spatial encoding within a selected slice and a uniform sampling of q-space using 64 values of the pulsed gradients to encode fluid flow. Because the pulsatile flows were axially symmetric within the resolution of the experiment, the radial variation of fluid velocity, in the direction of the pulsed gradients, was reconstructed from one-dimensional spatial projections of the velocity by exploiting the central slice theorem. Data were analysed for internal consistency using linearised flow theories. The results show that nonuniform q-space sampling followed by Bayesian probability analysis is at least as accurate as the combined uniform q-space sampling with Fourier velocity imaging and projection reconstruction method. Both techniques give smaller errors than a two-point sampling of q-space (the conventional flow encoding experiment).
