A spatial parallel mechanism namely 3-RRS mechanism has been assigned to be attached to the seat of a standard electric wheelchair to prevent the turning over of the handicapped sitting on the wheelchair. The system of the wheelchair and the mechanism is a self-balancing robotic wheelchair and has coped with several road conditions. A stability control system calculates the proper moments on th...

We have built a vertical seismometer that works based on the moiré technique. One grating is attached to the suspended mass and one to the frame of the instrument. The two gratings are in relative motion, and the resulting moiré pattern magnifies this motion. The intensity of a light beam passing through the moving moiré fringes changes with time, and a light detecting syst...

Cardiac papillary fibroelastoma (CPF) is a rare and benign primary cardiac neoplasm of unknown prevalence. The incidence of CPF in the left ventricle is lower than that in other parts of the heart. A 65-year-old female was referred to our cardiology department for evaluation of a cardiac mass of the left ventricle. Transthoracic echocardiography revealed a 1.8 × 1.7 cm highly mobile round mass ...

Vaginal leiomyomas are uncommon benign tumour with variable clinical presentation. These tumours arise most commonly from anterior vaginal wall. We report a case of 50-year old postmenopausal woman who presented with urinary retention, profuse vaginal bleeding and mass protruding into vagina.

A calcified amorphous tumor (CAT) of the right atrium (RA) is an exceedingly rare non-neoplastic cardiac mass. It was initially described in 1997 and only a handful of cases has been published so far. We present a case of tumor in 77-year-old male, in the RA that attached to the rim of the fossa ovalis, with classic pathological and clinical findings. Under cardiopulmonary bypass (CPB) and bica...

A 63-year-old female was presented to emergency room with an abdominal pain. The patient had moderate mitral valve stenosis and atrial fibrillation. Abdominal computed tomography revealed right renal infarction. Transthoracic echocardiography showed a large mobile mass in the left atrium. Transesophageal two-and three-dimensional echocardiography showed a large mobile ovoid mass with a narrow s...
