Abstract: Computerized Image Registration approaches can offer automatic and accurate image alignments without extensive user involvement and provide tools for visualizing combined images. The aim of this survey is to present a review of publications related to Medical Image Registration. This paper paints a comprehensive picture of image registration methods and their applications. This paper is an introduction for those new to the field, an overview for those working in the field and a reference for those searching for literature on a specific application. Methods are classified according to the different aspects of Medical Image Registration.

Abstract: Lot of research has gone into understanding the composition and nature of proteins, still many things remain to be understood satisfactorily. It is now generally believed that amino acid sequences of proteins are not random, and thus the patterns of amino acids that we observe in the protein sequences are also non-random. In this study, we have attempted to decipher the nature of associations between different amino acids that are present in a HIV protein. This very basic analysis provides insights into the co-occurrence of certain amino acids in a HIV protein. Such association rules are desirable for enhancing our understanding of protein composition and hold the potential to give clues regarding the global interactions amongst some particular sets of amino acids occurring in proteins. The aim of association rules mining is to reveal underlying interactions in large sets of data items. Knowledge of these rules or constraints is highly desirable for the in-vitro synthesis of artificial proteins. This will also give new insights to understand protein-protein interactions in HIV.

Abstract: The aim of this study was to develop a prototype generator with electro-acoustical connection, verify the parameters of the new apparatus, perform clinical trials in patients with normal hearing. A digital oscilloscope and artificial ear were used to check electrical and sound parameters. Sound intensity in the 0.5-20 kHz frequency range was 86.8 ± 9 dB SPL. This was followed by clinical trials involving 44 volunteers (17 men and 27 women) with an average age of 20. Before the experiment, each volunteer was examined by audiological tests to rule out damage to the auditory pathway. The upper frequency limit of hearing procedure consisted of binaural administration of constant-intensity signal with a frequency smoothly varying within the 20 kHz - 0.5 kHz range. The volunteer was told to release a signaling button when he heard the acoustic signal. At that moment, the generator stopped at a given frequency that was displayed on a digital scale unit. The test procedure was repeated three times in each subject and the arithmetic mean of three measurements was used in further analysis. The entire procedure, both technical and clinical, was conducted in an audiometric silent chamber, in which it was possible to control the acoustic conditions. Comparison of results of a prototype apparatus to the results obtained in previously research showed that the developed apparatus specifications meet their objectives. In clinical studies, the upper frequency limit of hearing results were as follows: in the group of 17 people only one person was below 75 percentile, two were at 75 percentile, ten at 50 percentile, and four were at 25 percentile. The results show that the modification of the apparatus involving the use of less expensive components has allowed to obtain the technical parameters and results comparable to the others authors and, therefore, the apparatus built by the author of this paper may be used as a screening apparatus.

Abstract: Falling is the crucial concern in elder adults which can result into serious injury or rupture of bones especially hip bone injury or other joint fractures. Hence fall detection is necessary to minimize risk of injury. Accelerometer is the most widely used device to detect falls as it provides information about the sudden downward tilt. Tri-axial accelerometer provides measure of acceleration in three dimensions. Paper describes the review on fall detectors in which tri-axial accelerometer is used as the main component along with different sensors and systems.

Abstract: Cancers are the most serious problems of the medicine. Adequate treatment of early diagnosed patient gives the patient possibility of healing, to improve the quality of life and to return to normal life. Most of the tumors are characterized by the presence of one or several more or less specific markers. By processing the presence of multiple markers - although with a lower sensitivity and specificity - we get an overall picture of the body organs. The aim of this project is to monitor, evaluate and process results of magnetic resonance imaging. The results are provided to doctors in the form of graphs, 2D and 3D models and tables. This application also brings the possibility of processing error values of the measurements of markers.
