For retrieving the relevant images from the internet, CBIRs (content based image retrievals) techniques are most globally utilized. However, the traditional image retrieval techniques are unable to represent the image features semantically. The CNNs (convolutional neural networks) and DL has made the retrieval task simpler. But, it is not adequate to consider only the finalized aspect vectors from the completely linked layers to fill the semantic gap. In order to alleviate this problem, a novel Hash Based Feature Descriptors (HBFD) method is proposed. In this method, the most significant feature vectors from each block are considered. To reduce the number of descriptors, pyramid pooling is used. To improve the performance in huge databases, the hash code like function is introduced in each block to represent the descriptors. The proposed method has been evaluated in Oxford 5k, Paris 6k, and UKBench datasets with the accuracy level of 80.6%, 83.9% and 92.14% respectively and demonstrated better recall value than the existing methods.

AbstractAmmonia is one of the most widely used chemicals in the processing industry. It is used as a refrigerant and substrate in various process fields. Almost every unit operation uses ammonia, and the storage and handling of ammonia require special attention in terms of inherent system safety. Controlling the catastrophic release of ammonia from the installed facility is a challenging process. In this paper, the resilient nature of the ammonia storage area in a fertilizer manufacturing plant in the southern part of the Indian subcontinent was considered. The resilience of the ammonia storage area is analyzed using the Resilience‐based Integrated Process System Hazard Analysis and statistically validated using one‐way analysis of variance (ANOVA). With the ANOVA validation method, the f‐values of subsystems are endorsed at a significance level of 0.05 both before and after recommendations were made. After implementing the statistically validated recommendations, the risk of each subsystem is significantly reduced. It has been determined that subsystems, namely process safety systems, operator/human hazards, and operational discipline require, immediate attention.

This paper investigates the effect of adding carbon based nano additives viz., graphene oxide (GO), multi-walled carbon nanotubes (MWCNT) and activated carbon (AC) to capric-lauric acid (CA-LA) eutectic phase change material (PCM) in order to prepare nanoenhanced PCMs (NEPCMs). Field emission scanning electron microscopy images showed that GO has a sheet, MWCNT has a tube, and AC has a sheet with porous like structures, which influence the shape stability of eutectic PCM. The CA-LA has melting and solidification temperature at 18.92 °C and 18.30 °C, corresponding latent heat values were 107.9 J g−1 and 106.8 J g−1 analyzed by differential scanning calorimetry. The addition of carbonaceous materials shows a slight decrease in the latent heat values for NEPCMs which is quashed by its improved heat transfer rate. Thermal stability of NEPCMs were studied by thermogravimetric analysis. As-prepared carbonaceous materials had excellent thermo-physical properties in that MWCNT has higher thermal conductivity compared to GO and AC due to it light weight. Therefore, NEPCMs has acceptable thermal properties which are suitable for cold thermal energy storage.

To improve the utilization of natural fibre reinforced polymer composites, this study experimentally investigated the properties and reinforcing effect of SiO2 nanospheres as fillers on mechanical, thermal and water absorption behaviour of luffa-coir hybrid nanocomposites. Structural studies were carried out by x-ray diffraction, and fourier transform infrared spectroscopy. Fracture surface morphology was analyzed by field emission scanning electron microscopy, which confirms the homogeneous dispersion of SiO2 nanospheres into luffa-coir/epoxy hybrid composite. The mechanical test results direct to the inference that hybrid nanocomposite containing 3 vol% of SiO2 nanospheres acquired 49.6%, 78.26%, 13%, 80% and 43.16% of improved tensile strength, tensile modulus, flexural strength, flexural modulus, and impact strength respectively, compared with epoxy composite. Hybrid nanocomposites exhibited better thermal behaviour than epoxy composite such as decomposition temperature and residual char were increased by about 10%, 136% respectively with reduced thermal conductivity. Also, they showed lesser water absorption behaviour as 0.14%. Based on the results, the developed hybrid nanocomposites could be an effective replacement of non-biodegradable plastic fibre products for automobile interiors.

Surgical instruments and other bioimplant devices, owing to their importance in the biomedical industry require high biocompatibility to be used in the human body. Nevertheless, issues of compatibility, bacterial infections are quite common in such devices. Hence development of surface coatings on various substrates for implant applications is a promising technique to combat the issues arising in these implant materials. The present investigation aims at coating copper on stainless steel substrate using DC Magnetron sputtering which is used to achieve film of required thickness (0.5–8[Formula: see text][Formula: see text]m). The deposition pressure, substrate temperature, power supply, distance between the specimen and target are optimized and maintained constant, while the sputtering time (30–110[Formula: see text]min) is varied. The sputtered copper thin film’s morphology, composition are characterized by SEM and EDAX. X-ray diffraction analysis shows copper oriented on (111) and (002) and copper oxide on (111) planes. The contact angle of copper thin film is 92[Formula: see text] while AISI 316L shows 73[Formula: see text]. The antimicrobial studies carried in Staphylococcus aureus, Escherichia Coli, Klebsiella pneumonia and Candida albicans show that the maximum reduction was seen upto 35, 26, 54, 39[Formula: see text]CFU/mL, respectively after 24[Formula: see text]h. The cell viability is studied by MTT assay test on Vero cell line for 24[Formula: see text]h, 48[Formula: see text]h and 72[Formula: see text]h and average cell viability is 43.85%. The copper release from the thin film to the culture medium is 6691[Formula: see text][Formula: see text]g/L (maximum) is estimated from AAS studies. The copper coated substrate does not show much reaction with living Vero cells whereas the bacteria and fungi are found to be destroyed.

An experimental study has been conducted in order to investigate the thermophysical properties of water-glycerol mixture-based nanofluids containing CuO nanoparticles, as phase change material (PCM) for cool thermal energy storage (TES) systems. The proportion of the water-glycerol in the mixture has been estimated as 80:20 (by weight) and the different mass fractions of CuO nanoparticles dispersed in the mixture are 0.1, 0.3, 0.5, 0.8, and 1.0 wt%, individually. The dispersion stability of the nanofluids employed as PCMs has been clearly ascertained by means of the sedimentation photograph and particle size analyzer. The thermophysical properties of the nanofluids, like phase change temperature and latent heat have been measured by differential scanning calorimetry. The thermal stability and reliability analyses were studied to evaluate the performance of the nanofluids for long-term operation. The effects of the concentration of nanoparticles and operating temperature of the PCMs on the viscosity of the nanofluids have been investigated. The laser flash analyzer has been used to ascertain the thermal conductivity enhancement of the nanofluids for all mass fractions of nanoparticles. The obtained results have shown that the prepared composite PCMs have achieved the desired properties, and they can be recommended as an efficient potential candidate for cool TES systems.

AbstractThis article presents a bandwidth improvement of a compact dual‐band slot antenna for 1.54/1.83 GHz cellular applications using a spiral‐like electromagnetic band gap (SEBG) structures. The rectangular slotted radiating element is surrounded by a SEBG. The antenna size is very compact (60 mm × 60 mm × 2.47 mm) and can be integrated easily with other radio frequency (RF) front‐end circuits. The working frequency of the patch antenna falls inside the electromagnetic band gap band gap which will lead to the suppression of the surface waves. The simulation is carried out using the finite difference time domain analysis technique. The bandwidth of SEBG antenna is 93.2% and 11.75% increased at lower and higher resonant frequency respectively than the patch. The EM simulated return loss, gain, directivity, radiation pattern, antenna efficiency, and voltage standing wave ratio (VSWR) are presented for proposed antenna array. Good agreement is achieved between the simulated and measured results. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:477–482, 2012; View this article online at wileyonlinelibrary.com.

This study describes the improvement of gain and bandwidth of a microstrip patch antenna achieved using a spiral-like electromagnetic bandgap (EBG) structure for high-speed wireless local area networks. The size of the antenna is only 45 × 45 × 2.47 mm and resonates at a frequency of 2.4 GHz. The gain and bandwidth of this antenna is 3 dBi and 67.4% greater than a conventional patch antenna. The working frequency of the patch antenna falls inside the EBG bandgap, which leads to the suppression of surface waves. Simulations of the antenna are conducted using the finite-difference time-domain analysis technique. The electromagnetic (EM) simulated and measured return loss, gain, directivity, radiation pattern, antenna efficiency and voltage standing wave ratio are presented for the proposed antenna array. These results allow one to determine the structures giving the best focusing performance and to obtain the frequency band for directive radiation.
