Wi-Pest:a method for detecting stored grain pests based on CSI
Published 2020-12-01“…The environmental and biological factors that affect the food security during the food storage,such as the food temperature,environment humidity,moisture,gas,mildew,pests and others pose a threat to the food storage security,among which the pest is an important factor threatening food storage security.Therefore,a fast and effective detection method is needed to detect stored grain pests.Some of the existing methods are time consuming,using expensive equipment,potentially harmful to health and inefficient.A non-contact,fast and low-cost detection method for stored grain pests based on the amplitude of the channel state information (CSI) was proposed,namely,wireless-pest (Wi-Pest).The feasibility of the pest detection in the stored grain was verified by using CSI amplitude data.On this basis,a Wi-Pest detection method was designed.Firstly,the amplitude data of CSI was preprocessed by outliers removal,data normalization and noise elimination.Then the principal component analysis (PCA) was used to compress the data and extract the main feature components.Finally,random forest (RF) classification method was used to detect stored grain pests.Experiments show that the abnormal density of live pests in grain heaps can be detected under the line of sight (LOS) scenario,and the detection accuracy of the proposed method can reach 97% on average.…”

Research on Freeze-thaw Resistance of High-strength Porous Concrete
Published 2021-01-01“…Because porous concrete is feature with a large pore structure and porosity,the freezing of water enriched in the pores in winter will have a greater impact on the performance of porous concrete.This paper puts forward the test method and evaluation index of the freeze-thaw resistance of porous concrete with reference to those of ordinary concrete,and systematically studies the effect of fly ash,slag,silica fume,fine sand and crack-resistant fiber on the freeze-thaw resistance of porous concrete.The results show that:The compressive strength of the prepared porous concrete is about 30.2~35.6 MPa for 28 days.The addition of fly ash,fine sand and fiber alone has no effect on the freeze-thaw resistance of porous concrete.Silica fume is beneficial to improve the freeze-thaw resistance.After adding 10% silica fume,when the number of cycles reaches 60,the dynamic elastic modulus can reach 66.8%,the mass loss rate is only 0.35%,and the freeze-thaw resistance index is 12.58.The porous concrete contains more connected pores,but it may still be damaged by volume expansion after water freezes.However,after adding silica fume,the freeze-thaw resistance of slurry is improved by increasing the amount of C-S-H gel,enhancing the adhesion between the interface and strengthening the interface.…”
