In order to prevent the thick labels from misalignment or out of position, via analyzing the working principle of label supplying system and the factors influencing the stability of label conveying and adopting toothed suction belt transmission technology, accelerated label conveying device in GDX1 soft packer was improved as following: 1) A pair of gears were installed on the shafts of accelerating wheel and driven wheel separately to make them synchronously rotating in opposite directions, and the driven wheel was driven by gears instead of by friction. 2) Labels were conveyed via the engagement of driven wheel and accelerating wheel, for ensuring a steady conveying process, the clearance between the two wheels was set at 0.05 mm less than label's thickness. The results showed that after improvement, the running speed of GDX1 packer increased from 320 to 360 packets per minute, the machine efficiency raised by about 6.3 percentage points, and the labels were conveyed more steadily. The working surface of driven wheel was away from the bearing and sliding seat, cleaning and maintenance became more convenient. Meanwhile the maintenance period was prolonged from 2 to 4 hours above. The improved accelerated label conveying device was adaptive for labels of various thickness. © 2016, Editorial Office of Tobacco Science and Technology. All right reserved.

Aiming at the problems, such as broken packet, packet missing or not properly filled, might happen in the process of cigarette production, a VPFE (Visual Perception Feature Extraction) algorithm based on the X-ray images of cigarette cartons was put forward. VPFE algorithm extracted the features of objects from the angles of visual perception including boundary, density, distribution, direction and regularity. Different classifiers were used to detect the abnormalities in cigarette cartoning. The results showed that: 1) VPFE algorithm offered pretty good detection effects under different classifiers, it could be applied to classification learning by mainstream classifiers and advantaged over other feature extraction algorithms in detection precision, which reached 100% for the detection of cigarette missing and packet missing. 2) VPFE algorithm could also detect the packets with a broken area over 20% or cigarette misalignment with detection rates of 95.8% and 96.6%, respectively. Cigarette or packet missing in cartons is eliminated, and the quality of cigarette packaging is promoted. © 2016, Editorial Office of Tobacco Science and Technology. All right reserved.

Dangling pointer error is a notorious memory error in C/C++ programs. It is hard to debug and is often leveraged to compromise the security of systems. This pa- per introduces an efficient runtime system to detect all dangling pointer error in C/C++ programs. Our work is based on a key finding: objects allocated in the same execution context are likely to be freed together. Based on this insight, we propose a new heap design and a new kernel page fault handler to detect accesses to already-freed objects. Compared with previous state-of-the-art work (introduces up to 21X overhead), our detector introduces acceptable runtime overhead (with 34%) and consumes less physical memory on allocation intensive benchmarks. © 2017 ICIC International.

A magnesium–aluminum layered double hydroxides coated on magnetic nanoparticles (Fe3O4@MgAl-LDHs NPs) combined with the supramolecular solvents (SUPRASs) as the magnetic supramolecular fluids were successfully applied to the extraction and determination of four phenolic compounds (Bisphenol-A (BPA), bisphenol-AF (BPAF), tetrabromobisphenol-A (TBBPA) and 4-tert-octylphenol (4-TOP)). Magnetic supramolecular fluids (ferrofluids) composites were prepared through adding the mixture of n-octanol and tetrahydrofuran in distilled water as the supramolecular solvents into the solution containing magnetic Fe3O4@MgAl-LDHs NPs. Under the optimized conditions, the calibration curve was obtained in range of 5–1000 μg L−1. The limits of detection (S/N = 3) for BPA, BPAF, TBBPA and 4-TOP, were obtained for 0.54, 0.48, 0.37 and 0.63 μg L−1, respectively. The intra-day and inter-day precision (RSDs %) for bisphenols (BPs) and 4-TOP at 100 and 300 μg L−1 were in the range of 4.0–7.8. The enrichment factors were between 16 and 24. © 2017

A sensitive and effective extraction technique based on magnetic solid phase extraction (MSPE) was developed for separating and detecting trace amounts of ultraviolet (UV) absorbers and light stabilizers in plastic packaging prior to high-performance liquid chromatography (HPLC). The magnetic Fe3O4/Au composites were synthesized by chemical co-precipitation, and a HAuCl4 solution was added to the Fe3O4 NPs, followed by the addition of hydroxylamine hydrochloride as a reducing agent for Au shell formation. The main factors affecting the adsorbability of UV absorbers, such as the effects of pH of the sample solution, the amount of adsorbent, extraction time, and desorption conditions on the magnetic nanoparticles (MNPs), were investigated and optimized. The proposed method showed good linearity in the range from 0.75 to 100 μg/mL with good presenting regression coefficients (R2) ≥0.9999. Low limits of detection (LODs) were achieved at 0.05, 0.14, and 0.04 μg mL−1 for 2-hydroxy-4-n-octoxy-benzophenone (UV-531), 2-tert-butyl-6-(5-chloro-2H-benzotriazol-2-yl)-4-methylphenol (UV-326), and 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV-328), respectively. The mean recoveries were in the range from 88.06 to 100.29% at 2.5, 5, and 10 μg mL−1 spiked levels, and the relative standard deviations (RSDs) were in the range from 0.98 to 3.56%. © 2017 Springer Science+Business Media New York

Tobacco Warehousing is chiefly applied to preserve the tobacco that is separated into leaf and stem so that the tobacco moisture is controlled at the range of technology demand.The present control method of tobacco save is that the references of every PID control link are set up and adjusted by human experience. So, the control effect varies with the individual and the output tobacco moisture can't maintain stable.The fuzzy-PID temperature system is based on CC2430 single chip. It includes the power source, the manipulative algorithm, the temperature examination, the correspondence of up PC and the output-control of the switch value and so on. Computer takes the parameter deviation and the deviation change as input, and the PID controller's parameters of ΔKp, Δki, ΔKd as output. The sub program realized the corresponding events by completing zone bit and zone bit judgment. The main program realized temperature control function by calling the wireless micro-controller sends a signal to the charged unit. © (2013) Trans Tech Publications, Switzerland.
