Etat : Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | Imaging is a significant diagnostic aid to the clinical evaluation of a patient with dental disease. Imaging has proven to be absolutely essential for accurate diagnostic in dentistry since ages; which makes even greater sense in recent times with rapidly revolutionising and evolving variety of radiographic modalities.After the discovery of X rays by Sir Wilhelm Conrad Roentgen in November 1895; the use of intraoral radiography commenced as early as within first months of 1896.Since then, dental radiography consisted pretty much of original twodimensional intraoral radiography which was used in making the first intraoral radiograph.The dental radiography was dominated primarily by intraoral periapical radiographs, bitewing and occlusal radiographs until the 1960s, when the introduction of panoramic radiography made it a valuable two-dimensional imaging option for the dental practitioners. The widened view of all teeth and supporting structures provided by the panoramic radiograph rendered a lot of information to the practising dentists from a single radiograph.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This suggested device is equipped with the aid of ultrasonic sensors to detect the target (missile, aircraft, drones etc.) approaching and automatically kill it. The ultrasonic transducer is rotated at 360 degrees and consists of a transmitter and a receiver. The sound waves are emitted from the transducer and the transducer receives them again from the target. The ultrasonic transducer is linked to the microcontroller of the PIC. When the target is recognized within the detection range, the signal is received by the microcontroller. On the microcontroller, the software assigned will move the launching application to the degree detected and aim towards the target. This proposed device uses an ultrasonic module connected to the 8051 family of microcontrollers. An ultrasonic transducer consisting of a receiver and a transmitter is used. The waves transmitted are reflected back from the object and are again received by the transducer. The cumulative time taken from sending to receiving the waves is determined by taking the sound velocity into account. The distance is then determined by a program running on the microcontroller and displayed via wireless communication on a liquid crystal display screen interconnected to the microcontroller.The circuit is used to receive 40 KHz reflected signals from the missile object, to feed them to the microcontroller program and to turn on the required load while the microcontroller is running the program. When the microcontroller receives the signal from the ultrasonic receiver, the door gun is triggered through a transistor or relay by triggering the MOSFET gate. The sensor is mounted on the antenna and is rotated and operated by a 360-degree stepper motor. The program will move the launcher to the nearest detected target and fire if there is any target inside the detection range.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - It is a well-known fact that economy of a nation highly depends on agricultural productivity.Occurrence of diseases in plants is quite natural. Thus, detection of diseases in plants forms a vitalaspect of enhancing agricultural productivity. Lack of proper care can cause serious effects onplants which in turn affects quality, quantity or productivity of the plant product. For exampleThe Great Famine (1845-1849) was a period of crop failure which led to diseases, massstarvation, emigration and death. Biologists later arrived at a conclusion that the famine wascaused by a potato blight, a natural event. Death was widespread and the toll rose to a 100,000.Automatic disease detection techniques can be used on crops in big farms, which will help reducethe manual monitoring of crops and detect disease or their symptoms at very early stages. Thisgives time for proper remedy. This paper presents an application with machine learning algorithmsto detect and classify diseases in tomato plants by processing images of the leaves.…
