Investigation of Sound Absorption Coefficient Using Delany Bazley Method

Current methods of measuring sound absorption coefficient and sound transmission loss of acoustic materials and treatments are time-consuming and expensive. To overcome this limitation, normal incidence sound absorption and transmission loss measurement technique using a flow resistivity tube were developed. Unfortunately, this equipment is equally expensive. This project is an effort made to develop a cost-effective flow resistivity tube for wider use especially for educational use in developing countries. A flow resistivity tube capable of measuring absorption coefficient and flow resistivity is designed and built under a budget suitable for educational institutions in developing countries. The design, development, and fabrication of the low-cost flow resistivity tube along with measurement results demonstrating its accuracy is presented. Using a calibrated acoustic sample, data obtained from the low-cost flow resistivity tube were compared with those from a standard commercial tube with encouraging results. A parametric study was conducted showing the effects of various parameters on the accuracy of the measured results. These include tube material, tube dimensions. Based on these, design options were generated to meet the cost and functionality targets pre-assigned. A list of suggested parts and price is also included for anyone interested to custom-build the tube.

Seebeck Effect to Generate an Electricity from Exhaust Gases of Automobile

In recent years the scientific and public awareness on environmental and energy issues has brought in major interests to the research of advanced technologies particularly in highly efficient internal combustion engines. Substantial thermal energy is available from the exhaust gas in modern automotive engines. The latest developments and technologies on waste heat recovery of exhaust gas from internal combustion engines includes thermoelectric generators, Organic Rankine cycle, six-stroke cycle IC engine and new developments on turbocharger technology. Thermo Electric Power Generator directly converts this Thermal energy into Electrical energy. So number of moving and rotating part has been eliminated. Thermoelectric power generation offer a potential application in the direct exchange of waste-heat energy into electrical power. By this it eliminated emission so we can believe this green technology. In this paper, a background on the basic concepts of thermoelectric power generation and its use in automobile engine is reviewed and discussed.

Wireless Rash Driving Detection System with SMS sending Facility and obstacle detection system

The rate of accidents occurring due to rash driving is increasing abruptly. The present system is able to detect the over speeding but it fails for further execution as it is time consuming. So, this system will be effective to replace the existing system. As the vehicle, will cross the permitted speed, SMS will be send to RTO as well as the system will help to avoid the unusual vehicle mishaps.

To Study Aetiology of Prostatomegaly and Corelations between Symptoms and Degree of Prostatomegaly

Dr. Noopur Priya (senior resident,general surgery), Dr.Gaurav Sali(neurosurgery resident),Dr.Kiran Kher (professor, surgery department); department of surgery,avbrh Prostatomegaly is one of the most common conditions affecting the ageing male. The effects of prostatomegaly on voiding function, however, vary greatly from patient to patient and thus make measuring its impact a challenging task.Three most common causes of prostate enlargement are benign prostatic hyperplasia (BPH), prostate cancer and prostatitis. Prostatomegaly affects the function of the urethra, urinary bladder, kidney leading to symptoms like Frequency of micturition, Nocturia, Dysuria, Hesitancy, Urgency, Lack of force and dribbling at the end, Haematuria, Retention, and symptoms of chronic renal insufficiency. Out of 166 patients enrolled in our study maximum patients were having grade III prostatomegaly.Benign Prostatic Hyperplasia was the commonest amongst all patients. The commonest symptom was increased frequency of micturition in our patients.AUA score was moderate to severe in grade I prostatomegaly patients while mild to moderate in grade III prostatomegaly patients, indicating that the symptom severity does not vary with respect to grades of the prostatomegaly.DRE showed all signs of malignancy in cases of carcinoma of the prostate.The age-adjusted Sr.PSA level was normal for benign disease of prostate and higher in carcinoma of the prostate.Carcinoma of the prostate was present mainly in grade III prostatomegaly patients.

Automatic Mammogram Tumor Detection Using Supervised Learning Method

Breast cancer is the most occupied type of cancer in women that caused the most deaths among women. The early detection of breast cancer is more important for the chances of survival of the patient. This work has mainly four modules: Pre-processing, Segmentation is carried out by Active Contour algorithm and Advanced K-means algorithm, Feature extraction is done by Gray Level Co-occurrence Matrix (GLCM), Expectation Maximization (EM) and Principle Component Analysis (PCA), finally classification is done by Random Forest Classification. To achieve the objective of this work, MIAS (Mammographic Image Analysis Society) and IN breast databases are used as input images. The Accuracy achieved in this system is 95.83%.

Feature and Processing Of Recognition of Characters, Words & Connecting Motions

Recognition & Modeling of characters, words & connecting motions is accomplished based on six-degree-of-freedom hand motion data. We address air-writing on two levels: motion characters and motion words. Isolated air-writing characters can be recognized similar to motion gestures although with increased sophistication and variability. For motion word recognition in which letters are connected and superimposed in the same virtual box in space, we build statistical models for words by concatenating clustered ligature models and individual letter models. A hidden Markov model is used for air-writing modeling and recognition. We show that motion data along dimensions beyond a 2-D trajectory can be beneficially discriminating for air-writing recognition
