Two-point contact is one of the fundamental problems wheel-rail in switch area. The state and distribution forces are complex essential points relationship. Given problem that current dynamic challenging to detect, a theory detect two-point area using discrete gauge column was presented proved finite element model.

Floating-point exceptions occurring during numerical computations can be a serious threat to the validity of computed results if they are not caught and diagnosed Unfortunately, on NVIDIA GPUs-today's most widely used types which do have hardware exception traps-this task must carried out in software. Given prevalence closed-source kernels, efficient binary-level tracking is essential. It also important know how flow through code, whether alter code behavior additionally these detected at...
Wheel polygonal wear is one of the most serious problems in railway industry nowadays. To study mechanism wheel wear, prediction model was established. The three-dimensional profile and improved USFD algorithm were used to research state wheel. vehicle system dynamic characteristics under different running speeds are studied. results show that vibration will be affected by vertical lateral coupling when considering wear. Due influence coupled vibration, appear larger wheel-rail force...

Target material identification plays an important role in many real-life applications. This paper introduces a system that can identify the type with cheap commercial off-the-shelf (COTS) RFID devices. The key intuition is different materials cause amounts of phase and RSS (Received Signal Strength) changes when radio frequency (RF) signal penetrates through target. However, without knowing either type, trying to obtain information challenging. We propose method address this challenge...
RFID-based positioning is emerging as a promising solution for inventory management in places like warehouses and libraries. However, existing solutions either are too sensitive to the environmental noise, or require deploying large number of reference tags which incur expensive deployment cost increase chance data collisions. This paper presents CSRP, novel RFID based system, highly accurate robust but relies on much less compared with state-of-the-art. CSRP achieves this by employing an...

Two-point contact is one of the fundamental problems in switch area. The state and forces are complex essential points wheel-rail relationship. Based on dynamic challenging to detect, a method detect two-point area using discrete gauge column was presented. From perspective column, decoupling strain bridge realized elastic deformation range. finite element calibrates bridge, test data results compared. show that can identify distribute characteristics force. And point position be deduced...
In the modern logistics environment, small and medium-sized transport enterprises are easily constrained by capital because of their short, frequent fast cash flow demand occupation funds resulting from purchase vehicles. However, can not provide enough fixed assets for pledge, in banks or other financial institutions reluctant to lend, prudent even lend. Multi-level principal-agent relationship is formed middle-level subcontracting business model supply chain. At same time, uneven...
