Quantum Cryptography has demonstrated the potential for ultra-secure communications. However, with quantumchannel transmission rates in the MHz range, typical link losses and signal-to-noise ratios have resulted in keyproduction rates that are impractical for continuous one-time-pad encryption of high-bandwidth communications. We have developed high-speed data handling electronics that support ...

Pseudo-random single photon counting (PRSPC) is a new time-resolved optical measurement method which combines the spread spectrum time-resolved method with single photon counting. A pseudo-random bit sequence is used to modulate a continuous wave laser diode, while single photon counting is used to build up the optical signal in response to the modulated excitation. Periodic cross-correlation i...

Counting the number of flows present in network traffic is not trivial, given that the naive approach of using a hash table to track the active flows is too slow for the current backbone network speeds. Several algorithms have been proposed in the recent literature that can calculate an approximate count using small amount of memory and few memory accesses per packet. Fewer works have addressed...

Understanding the number of people and the flow of the persons is useful for efficient promotion of the institution managements and company’s sales improvements. This paper introduces an automated method for counting passerby using virtualvertical measurement lines. The process of recognizing a passerby is carried out using an image sequence obtained from the USB camera. Space-time image is rep...

Vehicle tracking system is used for the observing vehicles on the move and supplying a timely ordered sequence of respective location data to model. Tracking vehicles on highways is a complex task since the count of vehicles increase day by day. The process of counting traffic along a particular road, either done electronically or by people counting by the side of the road is called vehicle cou...

Real-time image processing at high frame rates could play an important role in various visual measurements. Such image processing can be realized by using a high-speed vision system imaging at high frame rates and having appropriate algorithms processed at high speed. In this paper, we describe two visual measurements using highspeed vision, target counting and rotation measurement. For those m...

Lifted inference algorithms exploit repeated structure in probabilistic models to answer queries efficiently. Previous work such as de Salvo Braz et al.’s first-order variable elimination (FOVE) has focused on the sharing of potentials across interchangeable random variables. In this paper, we also exploit interchangeability within individual potentials by introducing counting formulas, which i...

A significant number of object detection models have been researched for use in plant detection. However, deployment and evaluation the real-time as well crop counting under varying real field conditions is lacking. In this work, two versions a state-of-the-art model—YOLOv5n YOLOv5s—were deployed evaluated cassava We compared performance when trained with different input image resolutions, imag...

background: amiodarone is a drug that is used for treatment of cardiac arrhythmia after cardiac ischemia. this drug as b blocker decreases arrhythmia rate but it has many side effects on different tissues. since there are rare reports about changes of lacrimal glands, this research has been carried out to study the morphological and ultrastructural changes of lacrimal gland cells after amiodaro...
