Morphometric Analysis of Larval Instar Stages of Reared Red Palm Weevil, Rhynchophorus Ferrugineus (Oliver, 1790), (Coleoptera:Curcolionidae)

This study was conducted to explore alternative morphometric characters that could be used to estimate the larval age of red palm weevil (RPW), Rhynchophorus ferrugineus. A total of 14 characters explored in the study. Morphological characters were measured using Image J software and data were analyzed using One-way analysis of variance (ANOVA), principal components analysis (PCA), and discriminant function analysis (DFA). One-way ANOVA excluded characters that are not different among instars, which were distal head band (DB), basal head band (BB), distal tail width (DT), tail ratio (TR), and head band ratio (HBR). All other characters were found to be significant at p < 0.05. For PCA, cumulative variations of 88.7% from the first two principal components, evidenced by sharp decrease in slope of the scree plot, has resulted from high loadings in dorsal surface area (DSA), total surface area (TSA), ventral surface area (VSA), head capsule width (HW), body length (BL) ranging from 0.955 to 0.984. For DFA, only one function explained a canonical correlation of 0.986 with 94.9% variation, and Wilk’s Lambda statistics of (0.007). The highest character loadings were BL, DSA, and HW, and could be useful characters in distinguishing instar ages of RPW larvae.

AUTOMATIC HEAD-MOVEMENT CONTROLLED WHEELCHAIR

This project is regarding the Motion controlled wheelchair for disabled. We are going to control motorized wheelchair using a head band having motion sensor and Arduino as controller. Problem: “often disabled who cannot walk find themselves being burden for their families or caretakers just for moving around the house. Disabled who are paralysed below head, who may not have functioning arms cannot control joystick controlled electric wheelchair.” This project is to solve their problem using a motion sensor to control their wheelchair. We are aiming towards building a more affordable, unique, low maintenance and available for all kind of head-controlled wheel chair.

Robo Control by Brain Signal

This research paper presents to develop a bio-signal acquisition system and rehabilitation technique based on “Cognitive Science application of robot controlled by brain signal”. We are trying to Developing a data acquisition system for acquiring EEG signals from Brain sense head band and also designing new algorithm for detecting attention and meditation wave and implementing on Robotics platform By using Embedded core.

Stereotactic Radiosurgery Head Phantom Bite Tray Fit Reproducibility

This research examines the accuracy of The Phantom Laboratory RSVP Phantom™ II with a jaw system that replicates patient biting. The research study examines the positional reproducibility as applicable for radiation oncology patients receiving stereotactic treatment. A bite tray was seated and locked into the phantom jaw system. Infrared passive fiducial array markers were attached to the bite tray. A head band containing a fiducial array was fit around the phantom skull. Ceiling mounted infrared cameras monitoring fiducial locations were used to calculate the spatial position of the bite tray relative to the stationary head band, as the bite tray was repeatedly removed, reinserted, and locked. For 100 sample mounts, the RSVP Phantom™ II jaw system proved to replicate the desired position with an average accuracy of 0.012 ± 0.001 mm and with a maximum difference of only 0.303 ± 0.001 mm. The innovation of the RSVP Phantom II jaw system is ideally suited for stereotactic radiosurgery and radiotherapy for commissioning and quality assurance.

A Simple Gaze Tracker for Computer Operation by the Disabled in Education

A compact gaze tracker was developed which consists of a head band and electrodes which process the Electro-Oculo-Gram (EOG) reflecting the patient´s eye movements. We have confirmed that the processed EOG signal correlates well with gaze angle, and we show that the instrument we designed enables a child to move a target on a screen up to 40 degrees left-right from central sight. To achieve this, a signal processing circuit was designed and placed on a head band to minimize noise. Further processing is based on the identification of saccadic eye movements and on the educated calculation of the estimated gaze angle as a result of angle change in both directions. A 75% success rate was achieved to detect transitions of eye positions in 5° steps from +40° to -40°. First tests by normal children suggest that the device may prove useful for communication by the disabled (e.g. patients with no control on hand movements). In such cases, extensive personal training will tap on neurological plasticity to achieve the required performance level for computer mouse command of educational games and for interactive applications in general.
