ARM Controller and EEG based Drowsiness Tracking and Controlling during Driving
No full textThis paper discussed about EEG-Based Drowsiness Tracking during Distracted Driving based on Brain computer interfaces (BCI). BCIs are systems that can bypass conventional channels of communication (i.e., muscles and thoughts) to provide direct communication and control between the human brain and physical devices by translating different patterns of brain activity commands through controller device in real time. With these signals from brain in mat lab signals spectrum analyzed and estimates driver concentration and meditation conditions. If there is any nearest vehicles to this vehicle a voice alert given to driver for alert. And driver going to sleep gives voice alert for driver using voice chip. And give the information about traffic signal indication using RFID. The patterns of interaction between these neurons are represented as thoughts and emotional states. According to the human feelings, this pattern will be changing which in turn produce different electrical waves. A muscle contraction will also generate a unique electrical signal. All these electrical waves will be sensed by the brain wave sensor and it will convert the data into packets and transmit through Bluetooth medium. Level analyzer unit (LAU) is used to receive the raw data from brain wave sensor and it is used to extract and process the signal using Mat lab platform. The nearest vehicles information is information is taken through ultrasonic sensors and gives voice alert. And traffic signals condition is detected through RF technology
Universal Automobile Headlight Control Module for High Beam Adaptation during Night Vision Travel an Embedded Design Approach
No full textRoad accidents during night travel increases day by day and vision impairment due to high beam contributes to the majority of the total fatalities. Headlights of vehicles pose a great danger during night driving. [1] The drivers of most vehicles use high/bright beam while driving at night. This causes a discomfort to the person travelling from the opposite direction. The driver experiences a sudden glare caused due to the high intense headlight beam from the other vehicle coming towards him from the opposite direction. We are expected to dim the headlight to avoid this glare. This glare causes a temporary blindness to a person resulting in road accidents during the night. To avoid such incidents, an embedded prototype of Automatic Headlight adaptor module is proposed. This embedded module automatically switches the high beam to low beam and returns backs to high beam, thus reducing the sudden glare effect. It also eliminates the requirement of manual switching by the driver to switch back to low beam Universal Headlight adaptor module is a unique solution to achieve the above objective, the headlight intensity of the incoming vehicles causing the glare is automatically attenuated to low beam wirelessly by the nearby vehicles affected by high beam. The interconnected modules at every vehicle independently takes the decision on the head light control of the source vehicle causing the glare by evaluating various parameters like vehicle speed, current GPS location, direction of vehicle etc
Localized Transient Stability (LTS) Method for Real-time Localized Control
No full textVery recently, a new methodology was introduced solely for the purpose of real-time localized control of transient stability. The proposed new method is based on the localized transient stability of a power system. This is completely a new idea in transient stability. In this method, the post-fault power system is represented by a two-generator localized power system at the site of each individual generator. If each of these localized power systems reaches its respective stable equilibrium, then the full power system also reaches its stable equilibrium. Therefore, in terms of real-time localized control of transient stability, if each of the localized power systems is driven to its respective stable equilibrium by local control actions with local computations using the locally measured data, then the full power system is driven to its stable equilibrium. Thus the method can be easily implemented for real-time localized control of transient stability. In this paper, the details of the mathematical formulations are presented. Some interesting test results on the well-known New England 39-bus 10-generator system are also presented in this paper to demonstrate the potential of the proposed method for use in real-time localized control of transient stability.

No full textGood patient safety culture of healthcare professionals brings about fine consequences for patients. This study, therefore, aimed in evaluating the current status and predictors of safety culture among healthcare workers in Mekelle Zone hospitals, Tigray, Northern Ethiopia. A cross-sectional survey was conducted among 325 healthcare workers in three hospitals of Mekelle city from February to May, 2017. Simple random sampling technique was employed to select study subjects. Data was analyzed using SPSS. Logistic regression was used to determine the predictors of patient safety culture among healthcare workers at 95% confidence level and 5% level of significance. Statistical significance was set at p <0.05. Of the 325 Healthcare workers, 21.6% rated the culture of patient safety as satisfactory and 78.4% rated as unsatisfactory. Old aged healthcare workers (AOR=21.9, 95% of CI: 2.51-61.69) and ‘hospital management support for patient safety’ (AOR=2.68, 95% CI=1.06-6.79) were strong predictor of satisfactory patient safety culture. Satisfactory patient safety culture grade obtained was only 21.6%, indicating that health care professionals are not delivering patient centered service and there is a lot of work to be done in the hospitals to improve culture of patient safety among healthcare workers.
