Abstract: Heart disease is one of the deadly diseases. Timely detection of the disease can prevent mortality. In this paper, an intelligent system is proposed for the diagnosis of heart disease using clinical parameters at early stages. The system is developed using the regularized deep neural network model (Reg-DNN). Cleveland heart disease dataset has been used for training the model. Regularization has been achieved by using dropout and L2 regularization. Efficiency of Reg-DNN was evaluated by using hold-out validation method.70% data was used for training the model and 30% data was used for testing the model. Results indicate that Reg-DNN provided better performance than conventional DNN. Regularization has helped to overcome overfitting. Reg-DNN has achieved an accuracy of 94.79%. Results achieved are quite promising as compared to existing systems in the literature. Authors developed a system containing a graphical user interface. Hence, the system can be easily used by anyone to diagnose heart disease using clinical parameters.

Abstract: Telecommunication devices such as ADSL modems or Wi-Fi routers are being widely used around the globe. Thermal management of such equipments are of critical importance as the increased power consumptions caused by technological upgrades results in increased heat generation within these systems. The heat transfer process inside such sealed and passively cooled equipments can be simplified as natural convection inside enclosures. Studying actual conditions inside electronic enclosure are necessary for their effective thermal management. This study aims at investigating the effect of non-isothermal heating inside such enclosures with linearly varying temperature distribution on free convection inside square enclosure. The issue of free convection of air interior of a square chamber with linearly varying temperature distributions on the left partition is studied numerically. The effect of change of Rayleigh number, temperature distributions, on flow and temperature field and rate of transfer of heat are analyzed. Rayleigh number is chosen to vary in between 103 and 106. Four different cases of linearly varying temperature distributions are considered. The outcomes are presented as stream line plot, isotherm contour and average Nusselt number. The outcomes depicted that case of linearly increasing temperature along the height gives higher Nusselt number than other cases.

Abstract Present technology used for soft material cutting robot are laser, water-jet, ultrasonic, plasma and oxy-gas cutting. The scope for designing and fabrication of soft material cutting robots are increasing due to its cost effectiveness and quality of cutting. Cartesian robots are mainly used in assembly and manufacturing applications. They also have a high degree of mechanical rigidity, accuracy, and repeatability. A previous work of more elementary kind was used as a skeleton model to start this work The purpose of the work is the maintenance and implementation of a 4 Degree of freedom robot and also to provide intelligence to the robot using fuzzy logic and neuro-fuzzy for soft material cutting. The kinematic modeling of robot manipulator is done using Denavit-Hartenberg (D-H) parameterization method and Euler-Lagrange method is used for dynamic analysis to determine actuator torque for each joint. The image is acquired with the help of the digital camera which is fixed in a suitable position so that it can scan the entire workspace. Prewitt edge detection algorithm was used for image processing and analysis. The signal for the cutting is interfaced through the Arduino Uno r3 controller.

Abstract The rare raninid crab Umalia trirufomaculata (Davie and Short, 1989) is recorded from India for the first time. It is redescribed and compared at length with the related but poorly known U. misakiensis (Sakai, 1937) on the basis of a good series of specimens from the Philippines. Some of the supposed differences which have been documented between the two taxa (e.g., carapace proportions and features of the cheliped) are not valid; while new distinguishing characters associated with the male pleon and gonopods are observed.

Abstract In this work, an integrated grey fuzzy logic technique is employed for solving the multi objective function of friction stud welding machine process parameters. This technique converts the multi-objectives into a grey fuzzy reasoning grade. According to the grey fuzzy reasoning grade, an optimal combination of process parameters is concluded. Here, Taguchi L9 orthogonal array is used to design the experiments. The objective of this work is to maximize impact strength and minimize metal loss during the joining of AA 6063 and AISI 1030 steel. Rotational speed, friction time, and friction pressure are considered as the input process parameters. The outcomes of the confirmation test show that good joining strength is accomplished by the optimal level of process parameters.

The gingiva is often the site of localized growths that are considered to be reactive rather than neoplastic in nature. One of these gingival lesions, seen rather infrequently, is peripheral ossifying fibroma (POF) a condition that predominantly affects women and is usually located in the anterior maxilla. The lesions are pink to red in colour, and firm to hard in consistency depending on their bone content. As enlargement occurs, they may become ulcerated. Concurrent poor oral hygiene and early periodontal disease are commonly seen. In most cases there is no underlying bone involvement evident on the radiograph. The definitive diagnosis is established by histological examination, which reveals the presence of cellular connective tissue with focal calcifications. Surgical excision is the treatment of choice, though the recurrence rate can reach 20%. This article presents a case of POF in a 14yearold female, from whom the tumour was excised using electrosurgery.

The beneficiation of iron ore slimes by selective flocculation was studied. Polyacrylamide (PAM) and guar gum were used as flocculant, along with sodium hexametaphosphate (SHMP) as a dispersant. The samples collected were initially subjected for chemical and mineralogical studies. The mineralogical studies indicated the presence of haematite and goethite as the principal iron-bearing minerals, with quartz and kaolinite as gangue minerals. The selective flocculation tests showed that the Fe grade can be enhanced from 58.24% to 64.60% Fe at a recovery of 66.33% using polyacrylamide as the flocculant. A Fe grade of 63.20% at a recovery of 68.04% was obtained using guar gum as flocculant. The efficacy of the studies was analysed using a separation index, which indicated that the higher separation index was obtained with the tests employing polyacrylamide as the flocculant.

INTRODUCTION: Primary leiomyosarcoma of bone is a rare entity which has never been reported in the foot. We report a case of primary leiomyosarcoma of metatarsal bone. CASE REPORT: A 60-year-old male presented with a history of pain, progressively increasing swelling and a non-healing ulcer over the dorsomedial aspect of his right foot. Plain radiograph showed an osteolytic, destructive lesion of the first metatarsal with involvement of surrounding soft tissue and bones. Magnetic resonance imaging showed a lesion that was hypointense on T1- and heterogeneous on T2-weighted images. Histology of the tumour with immunohistochemistry features aid in making the diagnosis of primary leiomyosarcoma of the first metatarsal bone, which was rare for this location. DISCUSSION: A brief review of the literature is done to determine the epidemiology, radiological and histological features and management of this tumour. CONCLUSION: Primary leiomyosarcoma of bone is a rare tumour and should be kept in the differential diagnosis of primary malignant osteolytic, destructive neoplasms especially in the older age group LEVEL OF EVIDENCE: therapeutic, IV

A large swelling in the facial region of long duration generally suggests benign etiology. We report a case of large asymptomatic swelling in the left facial region which was clinically diagnosed to be a benign salivary gland tumour. The radiological investigations also suggested parotid gland tumour of benign etiology along with a fortuitous discovery of a Stafne bone defect in the right angle of mandible. The histopathological report however confirmed the tumour to be a case of acinic cell carcinoma of the left parotid gland. The patient underwent total parotidectomy and postoperative radiotherapy and has been disease- free for the past three years without any evidence of residual or recurrent lesion. The clinical, radiological, histopathological, and therapeutic aspects of acinic cell carcinoma and the radiological evaluation of the Stafne bone defect are analyzed along with literature review.

This paper presents a comparison between some well-known control schemes such as feedback, feedback plus feed-forward, cascade and cascade plus feed-forward for controlling a third-order process. The controller applied in various control schemes is a PID controller that has been tuned using Ziegler Nichols (ZN) and relay auto-tuning (RA) methods. The comparative analysis is based upon various performance measures such as rise time (t r), settling time (t s), maximum overshoot (Mp), steady-state error (e ss), integral of absolute error (IAE), integral of square error (ISE), integral of time square error (ITSE), and integral of time absolute error (ITAE). Simulation results show that the RA method provides superior performance in case of feedback plus feed-forward and cascade control schemes. On the other hand, the ZN method proves to be better in case of cascade plus feed-forward control scheme.

This study intends to evaluate thermal ratchetting deformation due to cyclic thermal loading along the axis of a smooth cylindrical shell. Two cases of progressive deformation behaviour are discussed for different loading methods. The aim of the first case is to recognize the shakedown behaviour of the cylinder under applied loading cycles. Alternatively, second case is highlighting the ratchetting behaviour of the cylinder. Based on the loading method in second case, a smooth thin hollow cylinder is considered to simulate the progressive deformation. This condition simulates the 1/25th scale down model of the Prototype Fast Breeder Reactor (PFBR) main vessel.

The diagnosis of incomplete Kawasaki disease (KD) - i.e. cases that do not fulfil all the diagnostic criteria - requires a high index of suspicion. We report a case of incomplete KD that was refractory to treatment with intravenous immunoglobulin and subsequently responded to treatment with intravenous methylprednisolone.

Bilateral testicular tumours are rare, and 80% of bilateral tumours are metachronous. The incidence of testicular tumours is high in cryptorchidism. Synchronous bilateral testicular tumours are rare, and bilateral synchronous testicular tumours in bilateral cryptorchidism extremely rare, probably not reported previously.

The standard MRS components were optimized using response surface methodology for increasing yield of Streptococcus phocae PI80 viable cells and its bacteriocin. The highest amounts of bacteriocin activity and viable cells were recorded from prediction point of optimized MRS medium and achieved two fold higher (33049.8 AU.mL-1 and 14.05 LogCFU.mL-1) than un-optimized counterpart.

Phycoremediation is the use of algae for the removal or biotransformation of pollutants from wastewater. Employing this technology in the treatment of industrial effluents presents an alternative to the current practice of using conventional methods, including physical and chemical methods. In the present study, the effluent from a leather-processing chemical manufacturing facility, situated at Ranipet, Tamil Nadu, India, was treated using the microalga, Chlorella vulgaris, which was isolated from the effluent itself. The objective of this study was to treat the effluent as well as ETP (effluent treatment plant) solid waste by phycoremediation (pilot-scale field study as well as laboratory study) and to analyse the physico-chemical parameters before and after treatment. The results obtained showed that Chlorella vulgaris exhibited appreciable nutrient scavenging properties under both laboratory and field conditions, although phycoremediation carried out in sunlight (field study) gave better results. Moreover, the growth of Chlorella vulgaris was faster under field conditions.
