Adsorption is used for removal of pollutants and waste gases from liquid and gases effluent. Use of waste material for adsorption preparation makes this method more attractive. Regeneration of this adsorbent is very important aspect of the application of adsorption for various applications. Intensification of the adsorption bed includes reducing cycle time for pressure swing (PSA) and temperature swing (TSA) adsorption increasing thermal conductivity of the bed, optimizing various operating parameters. Regeneration of bed is an important aspect in adsorption desorption cycle as the low thermal conductivity of adsorbent is responsible for extended cycle time. To increase the conductivity, conducting materials in the form of composite fins can be uses. This review aims to study of different intensification technique for adsorption desorption process.

Face detection is a necessary first-step in face recognition systems, with the reason of localize and extract the face region from the background. It also has a number of applications in areas such as content-based image recovery, video coding, video conferencing, crowd observation, and intelligent human–computer interfaces. We have taken skin color as a tool for detection. This technique works well for all types’ faces which have a specific complexion varying under definite range. We have taken real life examples and simulated the algorithms in MATLAB successfully. This paper concentrates on the input images are converted to the YCbCr model to collect the value Y,Cb,Cr. and check whether these values are satisfied with the threshold values. If the pixels are in the range of threshold then that pixels will be considered as skin region otherwise it is a non skin region. This paper defined algorithm has been tested on various real time frontal images and gets better results for the YCbCr color model.

In the present work, an experimental investigation has been conducted to optimize the cutting parameters during turning of AA6061-T6 on Lathe in dry conditions. CVD made coated carbide inserts (WEDIA CNMG 120404, CNMG 120408) are used as cutting tools. Cutting speed (1000, 2000, 3000, 4000 RPM), feed (0.05, 0.1, 0.15, 0.2 mm/rev), depth of cut (0.5, 1, 1.5, 2 mm) and Nose radius (0.4, 0.8 mm) were considered as fixed parameters. A mixed level orthogonal array (L16) from taguchi has been adopted for the experiments. The multiple performances of Material Removal rate (MRR) and Roughness characteristics (Ra and Rz) were optimized by a hybrid Entropy-TOPSIS approach. The results revealed that the nose radius has the most predominant effect on the multiple responses.

The Economic dispatch is an important optimization task in power system. Thermal power plants are the major electrical energy producers. Need for renewable energy occurs due to the extinction of fossil fuels. Hence, it is necessary to operate these renewable plants with the thermal plants. In India, especially in Tamilnadu, Wind is the renewable plant which is widely available. The problem with the wind plant is its unpredictability.Hence, better wind thermal coordination economic dispatch method is necessary to integrate wind power reliably and efficiently. In this paper, Particle swarm optimization (PSO) technique is utilized to coordinate the wind and thermal generation dispatch and to minimize the total production cost. Ten units of thermal system incorporating wind power plant is utilized for numerical simulation. Different simulations with and without wind power production are simulated. Simulation result shows the effectiveness of wind power generation in reducing total fuel cost when compared with the genetic algorithm.

This paper deals with the structure of unified power quality conditioner (UPQC), which is used to eliminate power quality problems such as supply voltage and current harmonics, compensate reactive power, voltage sag/swell compensation on distribution system. The performance of the inverters depends on the control strategy used to generate reference signals for its operation. The mathematical analysis of UPQC is done to see its characteristic performance in the distribution system. This analysis is very useful for the selection of device rating and placement based on its particular application area in the power system.

Watermarking is an effective technology that solves many problems within a digitization project. A high capacity data entrenching scheme based on precise and fast framework for the computation of Zernike moments (ZMs) is proposed in this paper. The high capacity is achieved by maximizing data entrenching size and improving the hiding ratio after dipping the inaccuracies in the computation of ZMs. Furthermore, a concept of conditional quantization technique which enables to reduce the total number of ZMs needed to be modified during watermark embedding. Conditional quantization technique concept enhances the visual imperceptibility of the watermarked image and its robustness against various at tacks.

Maxillary defects are created by surgical treatment of benign or malignant neoplasms, congenital malformation, trauma and recently because of post covid mucormycosis. The size and location of the defects influence the degree of impairment and difficulty in prosthetic rehabilitation. Lack of support, retention, and stability are common prosthodontic treatment problems for patients who have had a maxillectomy. A prosthesis used to close a palatal defect in a dentate or edentulous mouth is referred to as an obturator. The obturator prosthesis is used to restore masticatory function and improve speech, deglutition and cosmetics for maxillary defect patients. The weight of the maxillary obturator is a dislocating factor because the prosthesis often acts as a cantilever. The laboratory procedure generally used in the construction of a hollow obturator is rather complicated. A more simple and accurate method which facilitates the processing of an obturator will be described. this article discusses about a modified technique to fabricate a two unit oral characterized and hollow detachable definitive obturator for rehabilitation of patient undergone bilateral maxillectomy after post covid mucormycosis.

This paper discuss and experimentally analyse the mechanical properties of TIG welded joints of similar and dissimilar grades of stainless steel and to find out the best joint. In this study. Different combinations from samples of AISI 304 and AISI 316 are welded under standard conditions by using Tungsten Inert Gas welding (TIG Welding) technique,.. The welded joints were tested for Tensile strength, Hardness and toughness and best combination is pointed out. The three combinations analysed were AISI 304-304, AISI 316-316 and AISI 304-316. It was found that the tensile strength and toughness of AISI 304-304 combination was highest and maximum hardness is observed in AISI 304-316 combination. The results indicate that there is not a single combination which excels in all tests.
