Published: September 2013

There was an indication that high rise buildings in Jakarta was not designed based on energy conservation principles. The most important aspects of the high-rise buildings is energy saving technology located in the building envelope design. Building envelope with a full glass design functions for widening view and enhancing natural lights, even though but it is also increasing energy consumption and thermal discomfort due to the intensity of solar radiation in hot humid climates. During the current decade, the development of double building envelope type (Double Skin Façade: DSF) seemed more just to improve the aesthetics and the use of natural light, while the wind and thermal performance aspects were still lack of serious consideration. Those aspects will be chosen as the subject matter in this research. The research was aimed to investigate and compare the value of heat transfer in the building envelope of high-rise office buildings. Samples were taken from five DSF buildings, with closed and open cavity. CFD software is used for simulation of the five different models of DSF. The research proves that the high-rise office buildings as the research object in Jakarta do not apply energy conservation principle. The utilization of wind in the DSF cavity can reduce temperature and relieve the burden of air conditioning systems that is energy save. An important finding of the research is the need for ventilation in the design of a double skin at high-rise office buildings in the humid tropics.

Authors: Zhang Sheng , Yang Xiang Hao , Li Xin Wen
Published: September 2013

t is one of precondition of determining rock material dynamic parameters for one-dimension assumption of the elastic pressure bar. In order to analyze its effect by loading wave type, the dynamic stress was simulated with Ls-dynamic finite element software, when SHPB(Split Hopkinson Pressure Bar) pressure bar with diameter of 50 mm, 75 mm and 100 mm were impacted respectively by a cycle rectangular loading wave and half sine loading wave. The stress waves of cross section in different diameter pressure bar and the different distance with pressure bar end were compared and analyzed. The results indicated that the dispersion of stress waves was very serious and the matching ability of stress wave at different distances in pressure bar was poor when the rectangular wave was loaded. However, the dispersion of stress wave was not obvious with the increase of the diameter of pressure bar and the change of pressure bar when the half sine wave was loaded. The half sine loading wave which can strictly meet the one-dimension assumption is one of the ideal loading waveforms of the rocky heterogeneous materials.

In this work, numerical coupled fluid-structure interaction (fsi) is simulated by the finite element method to extract understand the effects of air damping on the cantilever. Both static beam and vibrating beam are considered for the fsi calculation.

Authors: Zhang Xin Gong
Published: September 2013

This paper studies the issue of rescheduling to allow for the unexpected arrival of new jobs, taking into account the effect of the disruptions on a previously planned optimal schedule. We consider the single-machine rescheduling problems with deteriorating jobs. Rescheduling means that a set of original jobs has already been scheduled to minimize some classical objective, then a new set of jobs arrives and creates a disruption. The objective is to minimize the total tardiness costs under a limit of the disruptions from the original scheduling. We propose polynomial time algorithms or some dynamic programming algorithms for each problem.

Poly (styrene-co-acrylonitrile) supported TiCl4 was prepared and characterized. IR analysis shows that the absorption of the acronitrile group shifted from 2233cm-1 to 2277cm-1 after its coordination to TiCl4. It is found that this catalyst shows a much higher catalytic activity than that of TiCl4 in the preparation of sydiopolystyrene, especially, it can be used to prepare a styrene rich poly (styrene-co-ethylene), the resulted poly (styrene-co-ethylene) is a crystalline polymer shown a Tm much lower than that of a homo sydiopolystyrene. The molecular simulation result shows that the coordinated metal in the polymer catalyst is more cationic, probably due to an electron withdraw group coordinated to the central metal. This result can help us to understand that the polymer catalyst is more active and there is less cocatalyst MAO was used in the polymerisation process. Based on the results both of the experiment and the molecular simulation, we can give a conclusion that the polymer backbone stabilized the central metal Ti and make it difficulty to be reduced to a TiII complex, and the later shows no activity in the polymerisation. The stabilization is from the coordination of the polymer backbone and not due to an electron donor ligand which is in a normal metallocene.

Published: September 2013

Steel slag which is a byproduct of the steelmaking process was found to be a low cost and promising adsorbent for the removal of Copper from acidic wastewater. Batch experiments were conducted to study the main parameters such as dosage of adsorbent, particle size initial adsorbate concentration, contact time, kinetic, and pH solution on the sorption of Copper (II) by steel slag. By using linear Freundlich and Langmuir isotherms, the equilibrium adsorption capacity of steel slag for Copper was determined. The adsorption kinetics studies indicated that the data followed the second-order reaction with R2of 0.99. The study is aimed at research the potential of a novel use of steel slag for the treatment of wastewaters contaminated with heavy metals.

In this paper, a coupled numerical model of three-dimensional transient temperature field and degree of cure field for resin matrix composite curing process was developed. Using this model the hot-press curing process of the plate-shaped composite parts were simulated with considering the impact of tools and auxiliary materials. Thus, the temperature and degree of cure fields distribution in the entire process cycle were obtained. Numerical results show that the curing of the composite has a certain sequence. At the beginning, the composite is first curing at the boundary and gradually to the center. At the end stage, because of the higher curing rate, the center released a large amount of heat which makes the boundary curing simultaneously with center. In addition, there is a significant exothermic peak during the curing process. And the peak temperature is higher when it was closer to the center. This research effectively provides reference for optimizing the heating process parameters to improve product quality.

Once the pollution was found in a preliminary survey, the related information about the pollution site should be collected to confirm polluted range and quantity. Appropriate remediation technology is implemented until the pollution is completely remove. The more precise survey could lower the risk of uncertainty and improve the site remediation process. However, numerous of sampling and analysis should be done during whole process, including pollution survey, evaluation of remediation effectiveness, and verification after remediation. Time and budget needed for the remediation will be huge loads because of the widely range of site, and characteristics of the complicated pollutants, which may affect the remediation process. This study utilities Enzyme-Linked ImmunoSorbant Assay (ELISA) as the screening tool for dioxin pollutants by means of immuno-biological assay, which can complete the detailed investigation quickly and effectively, and also the pollution reclamation in a short time with the independent quality control. An appropriate screening method plays an important role for a successful and effective remediation.

The single-factorial design of experiments and response surface methodology was applied to optimize ultrasonic-assisted regeneration of coconut shell activated carbon. With the pH values of the solution, solid-liquid ratio, irradiation time chosen as the independent variable and the activated carbon release of antimony as response values, the central composite design method was used to study each of the variables and their interactions on coconut shell activated carbon regeneration. The results of this study showed that: the optimum pH value was 13; solid-liquid ratio was 372 mL·g-1; irradiation time was 6.7 h. The average content of the release of Sb from the activated carbon was 6233.95 μg·g-1 under the optimum condition. Regeneration rate of the activated carbon was 84.45%. This demonstrated that the adsorption efficiency of Sb was close in regenerative carbon and the original carbon. The results proved that the ultrasonic-associated coconut shell activated carbon regeneration process was accurate and reliable, and can provide a reference for the regeneration of coconut shell activated carbon which had adsorbed Sb.

20 kinds of wetland plant samples and their rhizosphere sediment samples were collected from Caohai in Guizhou Province to investigate the accumulation characteristics of heavy metals including Cu, Zn, Mn, As and Hg by these plants with different root systems in a Karst mountain area. The results showed that the accumulation coefficients of Cu, Mn, Zn, As and Hg by the wetland plants with taproot systems is 1.66, 1.50, 1.52, 1.64, and 1.56 times of those by the wetland plants with fibrous root systems respectively.Potamogeton lucensshowed the highest accumulation capacity to Cu, Zn and Mn among the collected wetland plants with the average accumulation coefficients of 6.42, 2.93 and 1.34, respectively.Hydrilla verticillatapresented a high accumulation capacity to Hg with an average accumulation coefficient of 3.27. None of the collected wetland plants met the criterion for super-accumulation plants. The results also indicated that the accumulation capacity of the heavy metals by the wetland plants was associated with the depth of their root penetrating into the sediment.

Published: September 2013

The affecting factors and kinetic characteristics of antimony (Sb) adsoption onto a type of the coconut shell activated carbon were investigated in this study. The results showed that: the Sb adsorption obeyed the pseudo-second-order kinetics equation, and the coefficients of determination (R2) were higher than 0.97, inferring that this process was mainly the monolayer chemical adsorption. With the reduction of the particle size, the adsorption capacity of activated carbon gradually increased. With the increase of temperature, activated carbon adsorption of antimony content increased gradually, but on the whole the temperature had a limited effect on the adsorption of activated carbon. Effect of the solution pH on antimony adsorption onto the activated carbon was mainly divided into the following two stages: with a pH value of 1 to 3, antimony removal rate was about 60%, and with a pH value of 5 to 11, the removal rate was about 20%.

With the demand for precision management of orchards, 3-D reconstruction of fruit tree canopy is receiving more attention. Using depth image data from Kinect sensor, this article attempts to find the 3-D coordinates of the sensed point on the canopy to get the reconstructed fruit tree canopy quickly. By slicing the point clouds to find its surface-line features and the outer envelope within the same slices is used to reconstruct the fruit tree canopy and calculate the canopy’s volume. Tests show that the measuring error for regular cuboid’s volume is about 4.2% and the repeated measuring error for citrus tree’s volume about 6.9%, indicating that applying Kinect for measuring volume of fruit tree canopy has reasonably high accuracy and reliability. The Kinect, as well as this technique, may well be used in landscape measurement on monitering.
