Public surveillance monitoring is rapidly finding its way into Intelligent Surveillance System. Street crime is increasing in recent years, which has demanded more reliable and intelligent public surveillance system. In this paper, the ability and the accuracy of an Adaptive Neuro-Fuzzy Inference System (ANFIS) was investigated for the classification of moving objects for street scene applications. The goal of this paper is to classify the moving objects prior to its communal attributes that emphasize on three major processes which are object detection, discriminative feature extraction, and classification of the target. The intended surveillance application would focus on street scene, therefore the target classes of interest are pedestrian, motorcyclist, and car. The adaptive network based on Neuro-fuzzy was independently developed for three output parameters, each of which constitute of three inputs and 27 Sugeno-rules. Extensive experimentation on significant features has been performed and the evaluation performance analysis has been quantitatively conducted on three street scene dataset, which differ in terms of background complexity. Experimental results over a public dataset and our own dataset demonstrate that the proposed technique achieves the performance of 93.1% correct classification for street scene with moving objects, with compared to the solely approaches of neural network or fuzzy.

Hybrid organic-inorganic materials are promising candidates and if their properties are tailored, several diffrent submicron planar optical passive and active devices, such as waveguides, ampli- fiers, splitters and couplers can be produced. In this present study, we report on sol-gel-derived organic-inorganic materials made from vinyltriethoxysilane (VTES). The lms were deposited on glass substrates by using a spin-coating technique. The lm densification was done at 300℃ and a patterned waveguide structure was fabricated by using UV-irradiation through a negative photomask. The SEM micrograph shows that channel patterns with a width of about 8 m were formed by etching of the unirradiated regions of the films.

In this research, an innovative Z-scheme vanadium pentoxide (V 2 O 5 )/graphitic carbon nitride (g-C 3 N 4 ) photocatalyst was synthesised using a facile thermal treatment method, and its photodegradation performance and physicochemical properties were evaluated. The heterostructure provided high Brunauer–Emmett–Teller surface area and pore volume, which encouraged charge carrier separation and transfer, as well as supplied abundant micro-mesoporous structures and active sites for photocatalytic redox reactions. The successful incorporation of V 2 O 5 between g-C 3 N 4 layers can be proven by proposing the synthesis mechanism, as well as conducting morphology, crystal structure, elemental, and chemical analysis through scanning electron microscopy, X-ray diff raction, energy dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy, respectively. Using these combined photocatalysts, ciprofl oxacin (CIP) was successfully degraded up to 90.17% removal effi ciency in the visible-light spectrum. The superior photocatalytic activity of g-C 3 N 4 composite over V 2 O 5 is primarily due to its increased light absorption capacity, as well as increased surface area, pore size, and volume, eff ective charge transfer, and optimal band alignment between g-C 3 N 4 and V 2 O 5 . This research provides a signifi cant future perspective for the utilisation of Z-scheme V 2 O 5 /g-C 3 N 4 heterojunction photocatalyst for water treatment, especially those involving endocrine-disrupting compounds and antibiotics like CIP.

Assisted reproductive technologies (ART) merely depend on improving the oocyte maturation and their developmental competence to produce good quality embryos. Oocyte maturation passes through long and complex molecular steps starts from the early embryonic life and ends with sperm fertilization. Oocyte developmental competence can be attained by improving the nuclear and cytoplasmic mechanisms together with some epigenetic maturation. In this review, we highlight the cornerstones of oocyte maturation on both nuclear and cytoplasmic levels. Interfering or supporting these molecular mechanisms would help in the development of novel regulating agents for reproductive performance of humans and livestock species.

Activated Carbon (AC) is an adsorbent having high surface area which makes the process of removing heavy metals fromwastewater (such as landfill leachate) very effective. This study explored the utilization of three methods of modification of ACproduced from coconut shell by treating it with nitric acid (HNO3), potassium permanganate (KMnO4) and heating at 600oC toimprove the adsorption capacity. The AC can remove multi-pollutants in the filtration process which was used to treat landfillleachate. The water quality parameters such as pH, TSS, Ammonia-Nitrogen and a few heavy metals were considered in the presentstudy. Results showed that the removal of these parameters was proportional with the increase of contact time and the bed depth ofAC. The isotherm analysis of the adsorption of modified AC showed the best Removal Efficiency (RE) can be achieved when ACtreated with KMnO4 for NH3-N, zinc, TSS and sulphide. The morphology of the AC was studied through Scanning ElectronMicroscopy (SEM), Energy Dispersive X-ray spectroscopy (EDX) pattern analysis and Fourier Transform Infrared (FTIR) analysis. It was found that various types of oxygen functional groups were introduced onto the surface of coconut shell derived AC throughoxidation using HNO3. FTIR was used to characterize the surface oxygen functional groups. The surface functional groups such asN-H and C-H stretching played a significant role in heavy metals adsorption. Hence, it can be concluded that the hybrid technique byusing electrolysis process with AC adsorption be an effective way to remove the suspended solids and heavy metals from landfillleachate and thus able to reduce environmental pollution.

Tailoring the properties of polyamide thin film membrane with layered double hydroxide nanoclay for enhancement in water separation

Tajuddin M.H.,Yusof N.,Fajrina N.,Salleh W.N.W.,Ismail A.F.,Jaafar J.,Aziz F. 한국물리학회 2022 Current Applied Physics Vol.34 No.-

This current paper presented a new candidate and potentially to improve the current membrane materials in water filtration process. With that, the primary materials used in this research study is layered double hydroxides (LDH) nanoclay which can be obtained from earth minerals and self-synthesized from inorganic salts were discussed thoroughly to help a better understanding of these materials. However, the current technologies of water separation were still lagging behind and ineffective especially in removal of divalent metal ions and multivalent salts. Infeasibility of reverse osmosis membrane make it not a viable option for divalent salts filtration. With that, nanofiltration (NF) membrane offered as an alternative to substitute available method. In this study, thin film nanocomposite (TFN) membranes were fabricated by incorporating layered double hydroxides (LDH) nanoclay. The LDH nanoclay with different loading ratio of 0, 0.05, 0.1, 0.15 and 0.2 were impregnated into polyamide layer on top of polysulfone substrates. The fabricated TFN were characterized in terms of physicochemical properties (SEM and FTIR) and membrane hydrophilicity (contact angle). After the addition of LDH, the morphological structures of TFN membranes were changed and the surface hydrophilicity was enhanced significantly. FESEM images displayed a typical ridge and valley morphology with nodule-like structures. As the LDH loading was increased, the contact angle decreased from 34.56◦ to 15.76◦ showing the surface hydrophilicity of membrane is improved. The separation performance of membrane was evaluated in terms of salt rejection ability by cross flow filtration system. The best performance NF membrane was found to be TFN 0.05 with high water flux and MgCl2 rejection with values of 24.18 L/m2.h and 91% respectively. This study has experimentally validated the potential of LDH materials in membrane process for improvement in water separation process.

Parametric study on earthquake induced pounding between adjacent buildings

Sadegh Naserkhaki,Farah N.A. Abdul Aziz,Hassan Pourmohammad 국제구조공학회 2012 Structural Engineering and Mechanics, An Int'l Jou Vol.43 No.4

Pounding between closely located adjacent buildings is a serious issue of dense cities in the earthquake prone areas. Seismic responses of adjacent buildings subjected to earthquake induced pounding are numerically studied in this paper. The adjacent buildings are modeled as the lumped mass shear buildings subjected to earthquake acceleration and the pounding forces are modeled as the Kelvin contact force model. The Kelvin model is activated when the separation gap is closed and the buildings pound together. Characteristics of the Kelvin model are extensively explored and a new procedure is proposed to determine its stiffness. The developed model is solved numerically and a SDOF pounding case as well as a MDOF pounding case of multistory adjacent buildings are elaborated and discussed. Effects of different separation gaps, building heights and earthquake excitations on the seismic responses of adjacent buildings are obtained. Results show that the seismic responses of adjacent buildings are affected negatively by the pounding. More stories pound together and pounding is more intense if the separation gap is smaller. When the height of buildings differs significantly, the taller building is almost unaffected while the shorter building is affected detrimentally. Finally, the buildings should be analyzed case by case considering the potential earthquake excitation in the area.

Zeinhom, Mohamed M.A.,Abdel Aziz, Rabie L.,Mohammed, Asmaa N.,Bernabucci, Umberto Asian Australasian Association of Animal Productio 2016 Animal Bioscience Vol.29 No.8

Heat stress negatively affects milk quality altering its nutritive value and cheese making properties. This study aimed at assessing the impact of seasonal microclimatic conditions on milk quality of Friesian cows. The study was carried out in a dairy farm from June 2013 to May 2014 at Beni-Suef province, Egypt. Inside the barn daily ambient temperature and relative humidity were recorded and used to calculate the daily maximum temperature-humidity index (mxTHI), which was used as indicator of the degree of heat stress. The study was carried out in three periods according to the temperature-humidity index (THI) recorded: from June 2013 to September 2013 (mxTHI>78), from October 2013 to November 2013 (mxTHI 72-78) and from December 2013 to April 2014 (mxTHI<72). Eighty Friesian lactating dairy cows were monitored in each period. The three groups of cows were balanced for days in milk and parity. Milk quality data referred to somatic cell count, total coliform count (TCC), faecal coliform count (FCC), Escherichia coli count, percentage of E. coli, and Staphylococcus aureus, percentage of fat, protein, lactose, total solid and solid non-fat. Increasing THI was associated with a significant decrease in all milk main components. An increase of TCC, FCC, and E. coli count from mxTHI<72 to mxTHI>78 was observed. In addition, the isolation rate of both S. aureus and E. coli increased when the mxTHI increased. The results of this study show the seriousness of the negative effects of hot conditions on milk composition and mammary gland pathogens. These facts warrant the importance of adopting mitigation strategies to alleviate negative consequences of heat stress in dairy cows and for limiting related economic losses.
