Random numbers have a wide range of usage area such as simulation, games chance, sampling and computer science (cryptography, game programming, data transmission). In order to use random in science, they must three basic requirements. First, the generated be unpredictable. Second, should good statistical properties. Finally, number streams not reproduced. generators (RNGs) been developed obtain with these These are classified into true (TRNG) pseudo (PRNG). One PRNGs used for generate is...

It is critical in terms of security that numbers used cryptographic systems are generated by hardware such as Field Programmable Gate Array (FPGA). The most common method to develop high-quality and fast True Random Number Generators (TRNGs) use Ring Oscillator (RO). Jitter mostly an approach provide randomness source clock signals RO so random can be generated. Numbers based TRNGs because jitter random. However, it a disadvantage these do not have good statistical properties....

For many of the applications in which wireless sensor networks are used, it is important to know from nodes or what location useful information acquired.The Global Positioning System (GPS) conventionally used determine location.However, GPS systems not ideal for due their excessive power consumption and high cost.As an alternative GPS, distance can be estimated through usage at least 3 with known locations.Received Signal Strength Indication (RSSI) simplest most inexpensive technique...

This article considers methodological approaches to determine and prevent social media manipulation specific Twitter. Behavioral analyses of Twitter users were performed by using their profile structures interaction types, classified according effect size values determining asset values. User profiles into three different categories, namely popular-active, observer-passive, spam-bot-malicious k-nearest neighbor (K-NN), support vector machine (SVM), artificial neural network (ANN) algorithms....

Abstract Urine sediment examination (USE) is an important issue in the detection of urinary system diseases and a prerequisite, especially diagnosis kidney diseases. The low‐contrast urine images contain many particles, these particles are superimposed or adherent, making it difficult to detect interpret particles. In this paper, YOLOv5‐based analysis system, which one fastest most successful architectures used for object detection, presented identify urine. artificial intelligence‐based can...

Obstructive sleep apnea (OSAS), which is one of the leading disorders and can result in death if not diagnosed treated early, most often confused with snoring. OSAS disease, prevalence varies between 0.9% 1.9% Turkey, a serious health problem that occurs as complete or partial obstruction respiratory tract during sleep, resulting disruption, poor quality paralysis even sleep. Polysomnography signal recordings (PSG) obtained from laboratories are used for diagnosis OSAS, related to factors...

The quality of randomness in numbers generated by true random number generators (TRNGs) depends on the source entropy. However, TRNGs, sources entropy are affected environmental changes and this creates a correlation between bit sequences. Postprocessing is required to remove problem created TRNGs. In study, an S-box-based postprocessing structure proposed as alternative structures seen published literature. A ring oscillator (RO)-based TRNG used demonstrate use S-box for removal...
