In this paper, a method for assessment of the ovarian follicle growth is presented. 3D ultrasound volumes of ovaries are processed. Ovarian follicles are shown as hypoechogenic areas in the cross-section images. In first phase, global translations and rotations of two observed follicle constellations from two consecutive ovary examinations are detected. In second phase, detailed local deformations are estimated using elastic registration. The proposed method has been tested using artificial simulated models of ultrasound images of ovaries. Preliminary results shows the proposed method is efficient and reliably detects deformations ovarian follicles cause by their growth.

This paper reports on the outcomes of evaluation recently conducted on Small Medium Enterprises (SME) in Malaysia with respect to a newly developed Software Process Improvement model called iSPA. It is conducted based on identified critical success factors for a software project to be successful. Initially, the evaluation investigates on the core process and best practices for a software project management and implementation. It also looks at the feasibility and acceptability of software companies to achieve this model and ended up with a tool development. The evaluation findings indicate the acceptance towards a new SPI methodology and relevance of the prototype tool to mitigate and assist in SPI implementation in an organization.

Reconfigurability in an antenna system is a desired characteristic that has been the focus of much interest in recent years. This paper describes the concept of reconfigurable antenna and how advances in switch technology have made these designs realizable. Complete design of the radiating patches, diode switches and biasing circuitry are also discussed. The structure of modified corporate-feed network is used to realize the array antenna consisting of 16 elements of rectangular patches at 2.3 GHz. The antenna patches through deployment of 4 PIN diodes switches at the feeding lines enabled the radiation pattern to be altered with respect to the beam shaping characteristics. While the planar arrays design making it more feasible for other antenna performances to be enhanced. The resistance for OFF and ON states of PIN diodes could strongly affect the performance of antenna. Hence, in order to improve the performance of the antenna, aperture coupled configuration is used to boost the antenna gain and directivity. The slot's geometry of aperture coupled antenna is stressed out as it determines the amount of coupling to the patches from feeding lines of the antenna. It is shown through simulations and measurements that 4 types of radiation pattern of the antenna can be well reconfigured by turning the diode switches on and off. The gain, directivity, beamwidth, efficiency and return loss are also changed. The proposed antenna, aperture coupled microstrip antenna array with quadratic slots, Q-ACMAA strengthen the level of coupling to the patches from feeding line with almost 50% of efficiency. Good agreement between the simulations and measurements were obtained. These results extend the validity of the analysis and will be useful for applications involving this type of reconfigurable antenna.
