Real-time kinematic (RTK) technique is widely used in modern society because of its high accuracy and real-time positioning. The appearance Android P the application BCM47755 chipset make it possible to use single-frequency RTK dual-frequency on smartphones. Xiaomi Mi 8 first Global Navigation Satellite System (GNSS) smartphone equipped with chipset. However, performance urban areas much poorer compared under open sky satellite signals can be blocked by buildings trees. can't provide...
The integration of the BeiDou Navigation Satellite System(BDS) and Inertial System(INS) can provide a more reliable accurate navigation service than either system alone. deeply coupled architecture for BDS INS has superior performance loosely or tightly coupled. Owing to complicated dynamic scenario nonlinear system's noise uncertainty, adaptive Kalman filter(AKF) algorithm is often adopted in deep integration(DI) system. Sage window methods including innovation-based estimation(IAE)...
This paper describes a hybrid AOA/TODA mobile station (MS) location estimation method based on the CDMA wireless communications signals. The utilized estimates angle of arrival (AOA) and time difference (TDOA) downlink pilot channel. In this paper, signal parameter estimations including AOA TDOA, position challenges in real systems are denoted. For estimation, mathematical model its linearized for TDOA/AOA Taylor series expansion derived. performance analysis high-resolution MUSIC double...
This paper discusses the fusion schemes of multiple sensors including accelerometer, gyro, magnetometer and pressure sensor for improved indoor positioning accuracy. The main focus is to make fully use complementary features in (such as gyro magnetometer) navigation structure PDR strapdown INS). A centralized Kalman filter designed implemented this integration. Tests are conducted at without using external wireless signal aiding. Positioning performance evaluated among different integration...
In urban environments, Global Navigation Satellite Systems (GNSS) signals are frequently attenuated, blocked or reflected, which degrades the positioning accuracy of GNSS receivers significantly. To improve performance receiver for vehicle navigation, a GNSS/INS deeply-coupled software defined (GIDCSR) with low cost micro-electro-mechanical system (MEMS) inertial measurement unit (IMU) ICM-20602 is presented, in both GPS and BDS constellations supported. Two key technologies, that is,...
The emergence of large multimodal models has unlocked remarkable potential in AI, particularly pathology. However, the lack specialized, high-quality benchmark impeded their development and precise evaluation. To address this, we introduce PathMMU, largest highest-quality expert-validated pathology for LMMs. It comprises 33,573 multi-choice questions 21,599 images from various sources, an explanation correct answer accompanies each question. construction PathMMU capitalizes on robust...
The navigation technology has developed rapidly and immensely over the past few decades. Among multiple technologies, representative promising techniques are Real-time Kinematic (RTK) technique Simultaneous Localization Mapping (SLAM). RTK can provide real-time positioning results with high accuracy, while SLAM not only locate user but also construct a map of new ambient. first smartphone, Xiaomi MI 8, equipped dual-frequency Global Navigation Satellite System (GNSS), hit market in May 2018,...
This paper introduces a novel double-differential vector phase-locked loop (DD-VPLL) for Global Navigation Satellite Systems (GNSS) that leverages carrier phase position solutions as well base station measurements in the estimation of rover tracking parameters. The use double differencing alleviates need estimating receiver clock dynamics and atmospheric delays; therefore, navigation filter consists baseline dynamic states only. It is shown using processing leads to significant enhancement...
Understanding the convergence properties of learning dynamics in repeated auctions is a timely and important question area auctions, with numerous applications in, e.g., online advertising markets. This work focuses on first price where bidders fixed values for item learn to bid using mean-based algorithms – large class that include popular no-regret such as Multiplicative Weights Update Follow Perturbed Leader. We completely characterize algorithms, terms Nash equilibrium auction, two...
Osteoarthritis (OA) is one of the most common chronic and progressive joint diseases characterized by cartilage degeneration chondrocyte death. In this study, we aimed to identify modulation effect miR-145 on chondrocytes' autophagy during development OA.
In this paper, We revisit the sponsored search auction as a repeated auction. view it learning and exploiting task of seller against private data distribution buyers. model such game between buyers by Private Data Manipulation (PDM) game: first announces an for which allocation payment rules are based on value distributions submitted The seller’s expected revenue depends design protocol played among in their choice (fake) distributions.
Decoding using tree search can greatly enhance the inference quality for transformer-based Large Language Models (LLMs). Depending on guidance signal, it searches best path from root to leaf in by forming LLM outputs improve controllability, reasoning ability, alignment, et cetera. However, current decoding strategies and their systems do not suit each other well due redundancy computation, memory footprints, access, resulting inefficient inference. To address this issue, we propose DeFT, an...
