Classification of Mammograms Using Decision Trees

L. Vibha, G Harshavardhan, K Pranaw, P Shenoy, K Venugopal, L Patnaik
2006 Proceedings - International Database Engineering and Applications Symposium  
Mammography is a medical imaging technique that combines, low-dose radiation and high-contrast, highresolution film for examination of the breast and screening for breast cancer. This paper proposes a Random Forest Decision Classifier (RFDC) for classifying mammograms. Results of screening the mammograms are organised by classification and finally grouped into three categories i.e., Normal, Cancerous and Benign. Experimental results show that this method performs well with the classification

Development of Wireless Technique to Regulate Seed Dropping in a Seeder for Intercropping

Korla Harshavardhan, S. S. Sivakumar, J. John Gunasekar, K. Balaji, P. K. Padmanathan, V. Alex Albert
2021 Current Journal of Applied Science and Technology  
Although intercropping gives additional yield per unit area than sole cropping, yield may also decrease as the crops differ in their competitive abilities. To avoid competition and to accompany complimentary action between the base crop and inter crop in intercropping practise, proper crop ratio of two crops should be maintained. When sowing with available seeders crop ratio was not maintained because of non-availability of a seed hopper, handling two different varieties of seeds and the un

To look after this problem an experiment was conducted at DFMPE, AEC & RI, Tamil Nadu Agricultural University, Kumulur by fabricating a seed hopper consisting of two compartments and circular shaped outlet for two variety of seeds and developing an RF (radio frequency) wireless technology to control servo motor in order to restrict the seed drop from seed hopper to the seed tube even though ground wheel is in running condition. In this paper considering a seven-row seeder, the performance of a micro controller coded with appropriate programme in embedded C language which can regulate seven servo motors each at seven seed hoppers, functioning of RF transmitter sketch, functioning of RF receiver sketch, header issue & its solution, angle conversion of servo shaft and power consumption was observed and discussed. Total power required for operating RF electronic setup containing seven servomotors was recorded as 5 V 12 A. The angle of rotation of servo motor shaft was from 0º to 165º when pulse width range in micro controller was set from 0 and 2400 micro seconds. The servo did not respond in the hardware interfacing because both the libraries use timer 1 interrupt which created an error issue. In order to overcome that "Servo timer 2.h" header was issued instead of servo.h. Then sketch was compiled and was executed successfully.

DORSAL COMPRESSIVE MYELOPATHY DUE TO OSSIFIED YELLOW LIGAMENT - A COMPARATIVE STUDY
English

Hayagriva Rao B, Satyavara Prasad K, Harshavardhan B, Sandeep B, Vijay Kumar P
2015 Journal of Evidence Based Medicine and Healthcare  
INTRODUCTION The well-known causes of Dorsal myelopathy are Koch's Spine and Metastasis. Ossified Yellow Ligament is a rare cause, endemic in some parts of the world. With advances in imaging techniques, preoperative evaluation and diagnosis has become easier. MATERIALS AND METHODS Twenty-one cases of Dorsal ligamentum flavum thickening causing compressive myelopathy have been studied and evaluated with Nurick grading preoperative and post-operatively. The age distribution, presenting

Parasthesias are present in all most all cases. Lower dorsal segment is solely involved in females whereas multiple level involvement is common among male patients. Male patients usually develop sudden onset of symptoms with trivial fall.

UNUSUAL VISION IMPROVEMENT IN A CASE OF SLIT VENTRICLE SYNDROME AFTER ENDOSCOPIC THIRD VENTRICULOSTOMY
English

Ravi Dasari, Satyavara Prasad K, Vijay Pallikonda Kumar P, Harshavardhan B
2015 Journal of Evidence Based Medicine and Healthcare  
Slit ventricle syndrome is a rare condition where brain compliance is reduced. It is associated with intermittent intracranial hypertension. It has been typically observed in older hydrocephalic children operated in early infancy, even though it has been observed occasionally in young children and adults. Endoscopic third ventriculostomy (ETV) is difficult in slit ventricule syndrome because of collapsed and fibrosed ventricles. In our case, patient had symptomatic improvement after endoscopic third ventriculostomy.
