Повний текст джерелаThe crescent utilization of concrete which in terms of volume, is the most produced product in the world, added to the pressure of the market to reduce the costs and maintenance of the safety minimum requirements of a project, make a direct impact on the material quality control’s importance and necessity. For ready-mixed concrete, mostly seen in large urban centers, the initial and final 15% usage of its total volume is not recommended by the country standards for test purposes. However, due to the ease, it is a common practice in construction sites of the region to collect samples once the first portion of the concrete is unloaded. Taking into account such procedure, which does not meet the standards recommended, added to the lack of standardization to assess the quality of the concrete mixer, the uniformity of the concrete mixture and the importance of the quality control tests of concrete under the safety of structures, the purpose of this research is to analyze the variations of the concrete strength when compressed and its physical properties along the discharge of the mixture made in a mixer truck. In order to achieve the proposed goal, there were sampling carried out at five different points along the discharge from the concrete mixer truck, for each of the 65 lots (batches) analyzed, considering three different types of concrete. Each sampling collected was analyzed by going through a slump test, compression strength and granulometry analysis. Statistically, it was proven that the sample point collection variation of some of the batches influences the compression strength, on the other hand the same cannot be found considering the ABECE criteria, used as analysis parameter in the absence of specific regulations for the subject. No representative profile of resistance variations based on the sample collection point was formed, in contrast to the coarse aggregate content, in which profile can be clearly seen a concentration of gravels at the extreme points, at the commencement and the end of the sample collection. Regarding its consistency, on the whole, there was a reduction from the initial and to the end point, respecting the regulations standards.

Повний текст джерелаIn this study, the main emphasis is placed on the development and characterization of alkali-activated binders completely produced by the use of mixed construction and demolition waste (CDW)-based masonry units as aluminosilicate precursors. Combined usage of precursors was aimed to better simulate the real-life cases since in the incident of construction and demolition, these wastes are anticipated to be generated collectively. As different masonry units, red clay brick (RCB), hollow brick (HB) and roof tile (RT) were used in binary combinations by 75-25%, 50-50% and 25-75% of the total weight of the binder. Mixtures were produced with different curing temperature/periods and molarities of NaOH solution as the alkaline activator. Characterization was made by the compressive strength measurements supported by microstructural investigations which included the analyses of X-ray diffraction (XRD) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDX). Results clearly showed that completely CDW-based masonry units can be effectively used collectively in producing alkali-activated binders having up to 80 MPa compressive strength provided that the mixture design parameters are optimized. Among different precursors utilized, HB seems to contribute more to the compressive strength. Irrespective of their composition, main reaction products of alkali-activated binders from CDW-based masonry units are sodium aluminosilicate hydrate (N-A-S-H) gels containing different zeolitic polytypes with structure ranging from amorphous to polycrystalline.

Huge data processing contributes many factors in wireless sensor network (WSN) such as network traffic and energy constraint. Wearable devices have become widely used to monitor body signals for long-term health care and home care applications. They detect vital signals through physiological sensors and then transmit them to a cloud database for evaluation and monitoring purposes through wireless communication systems. These wearable devices also need to pay attention their power consumption. This dissertation is divided into parts, applying two different data compression techniques for reducing the power consumption of WSN and wearable device. Using compressive sensing a new technique in data acquisition which reduced the required sampling rate to reconstruct the original signal will therefore lessen the power consumption of the WSN. The primary objective of the design is to reduce the power consumption on wireless system network by maximizing the data packet payloads while minimizing the transmission activity of the Wireless Sensor Network. The sensor and receiver node consume more power when transmission of data is taking place. Fast Fourier Transform (FFT) will determine the sparsity of the signal; the measurement matrix contains the large coefficients and orthogonal matching pursuit was used for the recovery of the original signals. Matlab was used to simulate the results of the compressive sensing algorithm. On the other hand, a smart analog-to-digital converter (ADC) was realized by a mixed-signal application-specific integrated circuit (ASIC) based on adaptive resolution and lossless compression techniques for electrocardiogram (ECG) signal monitoring. The sampling clock for the ADC can be adaptively selected according to the characteristic of the signals. The lossless encoder consists of trend forecasting and entropy coding modules. The transmission data rate was decreased efficiently by adaptive resolution and lossless compression techniques. The chip aims to meet the low power consumption for the design because it reduced the signal transmission rate and maintained high-quality ECG signal detection. The mixed-signal ASIC design was realized using a 0.18 μm CMOS process with a total power consumption of 78.8 µW when operating at 1 kHz and a total chip area of 850 × 850 μm2.

In this thesis, we propose an adaptive block truncation coding method (ABTC) for image compression. For achieving a better image quality, we propose a novel algorithm by a mixture of a upwind finite difference for solving a time dependent convection diffusion equation and the ABTC algorithm to remove the image noise. The numerical results show that our proposed methods are effectively remove the noise, and preserves the edge information well during the image compression process.

Three-dimensional visual communications, made through the use of stereoscopiimages, are able to achieve total display realism. In order to create a 3-D system with two images ( left and right) that must be transmitted simultaneously, the large amount of information contained in the images must be reduced, and an efficient coding appropriate for stereoscopic images developed. Stereoscopic image sequence compression involves the exploitation of the spatial redundancy between the left and right image fames to achieve the compression ratio higher than that are by the independencompression of the two frames. In order to further achieve the higher compression ratio, in this paper, we empoly the mixed-resolution psychophysical experiments to the stereo image compression. The experiments have shown that a stereo image pair with one high resolution image and one lower resolution image is sufficient to provide good stereoscopic depth perception. Thus, one image sequence is compressed independent of the other sequence using the motion compensation, while the other sequence is estimated at a lower resolution from this stream using the low resolution disparity compensation. To implement the mixed-resolution coding, a wavelet multiresolution framework has been adopted to facilitate such an estimation of motion and disparity vectors at different resolutions. Experimental results indicate that the compression ratio for a typical stereoscopic image sequence is about 90, without any significant loss in the perceived 3D stereoscopic image quality.

In this study, soil at the different coefficient of uniformity (CU) were added at different proportion (5%, 10%, 15%, 20%) and the Ground Improvement Admixture (HSC301) conditioner and Type I of the soil cement mixture by mixing. Firstly, the experimental value of the soil PH test to gain a better understanding of soil and examine if the pH is greater than 5.3. According to ACI study, if cement solidified soil PH value exceeds 5.3, it will help to enhance the cement hydration, then investigate the relationship between compressive strength with different curing periods of 3 days, 7 days, 14 days, 28 days separately. Additionally, it is required to examine inter-relationship of the pH value, best water maximum and dry density of soil versus HSC301 and soil versus cement modifier The results showed that soil at the different coefficient of uniformity (CU) mixes with the Ground Improvement Admixture at the different proportion mixtures and type I cement, its compressive strength increases with the ages; and also increases along with the geological of modifier and type I cement increases. The compressive strength of the soil- Ground Improvement Admixture mixture is higher than that of the soil-cement mixture. PH value of the soil mixture increases along with the Ground Improvement Admixture and Type I cement increases; and the compressive strength of soil mixture also increases with the PH value. Moreover, the optimum moisture content for the soil - geology modifier mixture and for the soil - cement mixture increases with reducing of the Ground Improvement Admixture and Type I cement, otherwise the maximum dry density had reverse results.

The paper of the proposed project is to design P60S mixed-flow compressor and applied the current quasi and fully 3-D turbomachinery flow analysis to assist the P60S compressor design. The proposed research aims to integrate the advanced mixed-flow compressor flow analysis system for the use of small gas turbine power and propulsion systems. To assist the P60S compressor design, the analysis system has incorporated the current available turbomachinery flow analysis tools used in gas turbine industry. The IDEAS will generate the finite element mesh for structure analysis in ANSYS while the solid modeling of compressor component is CAD in IDEAS. The unified database developed has been able to generate the input of the analysis tools both from NREC compressor design system and BPAD blade design system. This interaction will reduce the iteration time between compressor design and analysis. The presented results include the P60S mixed-flow compressor design parameters, lay-out and CAD modeling, quasi 3-D and fully 3-D flow analysis for the impeller, 1st and 2nd diffuser and deswirl vane, and structural analysis on ANSYS.

The bottom residue and fly ash are produced from municipal solid waste incinerator. Bottom residues can be disposed in landfill and as material for permeable brick. But fly ash was not easy to recycle, because it contains much heavy metal. Although significant achievements in applying fly ash to cement mortar and concrete have been obtained, but the weaker compressive strength at the early curing age is still a problem, and needs to be improved. This study is aimed to improve the weaker compressive strength of the MSWI fly ash slag blended cement mortar at the early curing age. First, we try to add the nano CaCO3 slurry to the cement mortar. Second, we molded the same cement mortar but added nano SiO2 slurry. As aforementioned, the two compressive strength tests had good results in strength improvement. Then we try to use the chemical mechanical polishing (CMP) sludge of the semiconductor industry waste water to replace 0~20 wt.% cement, and to mold the cement mortar specimens for testing. Because the waste sludge contained large amount of SiO2 nano-particles, and the compressive strength test of these specimens had good result. Therefore, for obtaining the highest strength, the experiment design of three levels and four factors (cement, slag, CMP quantity, and water to binder ratio) was selected to have the nine kinds of specimens for testing. The test results revealed the strengths of some kind of specimens were stronger than the ordinary Porterland cement mortar after three days of curing. Thus the early stage compressive strength of MSWI fly ash slag blended cement mortar was improved. Finally, the experimental design for compressive strength was successful and confirmed. The test results showed that the best mixture proportion was w / b = 0.485, cement amount = 80 wt.%, MSWI fly ash slag amount = 17 wt.%, and CMP sludge amount = 13 wt.%, which had the highest compressive strength. The test results revealed that both the MSWI fly ash and CMP sludge cauld be recycled as admixtures to cement mortar, and was good for sustainable environment.
