Automatic road sign recognition is one of the most important steps to help a driver prevent accidents. In this paper, the deep convolutional neural network (Deep CNN) was used for the autonomous traffic and road signs detection and recognition system. The proposed system works in real-time recognition of the image of road signs. The contribution of this article is that it consists of a newly developed datasets for 42 different road signs using combination of existing datasets and collected local road signs. The images were taken from different angles and included other parameters and conditions. More than 30K images were collected to create the dataset, which is named Uzbekistan traffic and road signs (UZ-TRS-2021). The CNN architecture was used with various parameters to achieve the best recognition speed. Experimental results show that the proposed CNN architecture achieved 98% accuracy. © 2021 IEEE.

A growing number of human-centric tasks like learning, planning, and creative writing require the integration of Artificial Intelligence (AI) in the current era of exponential advancements. Such systems collect and analyze data on their own making the best use of available resources and providing creative solutions for challenging issues. The impact of AI on productivity, data analysis, flexibility, and real-time decision- making in a variety of fields is examined in this paper. Focusing on academic settings, the paper considers ethical concerns surrounding AI-generated content. According to a survey, even though many students use ChatGPT for writing and research, worries about academic integrity and plagiarism still exist.

No-Pose (NP) tracking systems rely on a single sensor located at the user's head to determine the position of the head. They estimate the head orientation with inertial sensors and analyze the body motion to compensate their drift. However with orientation drift, VR users implicitly lean their heads and bodies sidewards. Hence, to determine the sensor drift and to explicitly adjust the orientation of the VR display there is a need to understand and consider both the user's head and body orientations. This paper studies the effects of head orientation drift around the yaw axis on the user's absolute head and body orientations when walking naturally in the VR. We study how much drift accumulates over time, how a user experiences and tolerates it, and how a user applies strategies to compensate for larger drifts.

Sharing writing responsibilities for a set of manuals between two distinct company sites poses unique challenges. In the authors' experience, the situation requires clear communication using electronic technology; mutually understood, accepted, and followed agreements; and dedication to teamwork. These result in timely completed manuals, as well as in camaraderie and synergy among members of the team.

In modern circuit design, the Shannon decomposition of switching functions is widely used. On the other hand, in information theory of telecommunication, the Shannon entropy used as a measure to represent the information in numerical values, is a key notion. In this paper, we relate these two concepts, belonging to different areas, into an approach to the minimisation of exclusive-or sum-of-products (AND/EXOR) expressions for switching functions. The Shannon decomposition, and the closely related Davio decomposition for AND/EXOR expressions are interpreted in terms of basic concepts in the information theory. Thanks to that, we have proposed an entropy based strategy for minimization of AND/EXOR expressions. We have provided a comparison and an experimental verification of this strategy with some known heuristic minimization strategies using benchmarks. In some cases, our program Info-EXOR produces extremely better results. Moreover, the information theory interpretation of classical decomposition of switching functions offers a new point of view to the existing design styles. © 1999 IEEE.

Many satellite systems require knowledge about inter-satellite distances. Inter-satellite links provide direct connectivity between satellites and may be used for ranging, while they remove the need of dedicated hardware. This paper addresses inter-satellite ranging at the Low Earth Orbit (LEO) using S-Band signals. We take the requirements from recent missions and future applications into account and analyze the factors that limit ranging. We show how these factors affect the quality of distance estimation in terms of the Cramér-Rao Lower Bound for ranging. Two-way-ranging (TWR) provides the best accuracy and sustains the low-cost objective of small satellites. We further propose an enhanced TWR message exchange that enables on-the-fly delay calibration and sub-sample corrections. We implemented the transceiver modules on a Software-Defined Radio (SDR) platform and evaluated them with real-world data. The results show that the proposed ranging algorithm achieves an accuracy of few centimeters.

This work presents the performance of WLAN and MANET networks using the auto-configuration of Mobile IP Agents Protocol (DRMIPA). This scheme would allow groups of MIP nodes in WLANs or MANETs to enjoy IP mobility at any foreign or local network that doesn't implement MIP. To maintain a failure free MIP network, a passive agent is elected from an active agent if this active agent leaves or ceases its participation from current network. The DRMIPA protocol is implemented in WLAN and MANET. A performance analysis is done using a real world testbed scenario.

The system FT/sub /spl les// of ordering constraints over feature trees has been introduced as an extension of the system FT of equality constraints over feature trees. We investigate the first-order theory of FT/sub /spl les// and its fragments, both over finite trees and over possibly infinite trees. We prove that the first-order theory of FT/sub /spl les// is undecidable, in contrast to the first-order theory of FT which is well-known to be decidable. We determine the complexity of the entailment problem of FT/sub /spl les// with existential quantification to be PSPACE-complete, by proving its equivalence to the inclusion problem of non-deterministic finite automata. Our reduction from the entailment problem to the inclusion problem is based on a new algorithm that, given an existential formula of FT/sub /spl les//, computes a finite automaton which accepts all its logic consequences.
