In this paper, we propose a new architecture for analog-to-digital converters (ADCs) using multistate spatial wavefunction-switched field-effect transistors (SWSFETs). SWSFETs are multiple quantum coupled well devices, where the wells are stacked vertically and the electron wavefunction switches from one well to another with the change in gate voltage. Quantum mechanical simulations of 3-well InGaAs-AlInAs SWSFET structures are presented. The designs and simulations of 2-bit and 3-bit ADCs using SWSFETs result in low power consumption and reduced device count which improves the speed of the data conversion.

A modality to boost up the abilities of simple sensors for providing extended configurability options and plug-and-play capability along with great scalability, integrability, rapid customization and modularity is reported in this paper. An embedded architecture that requires both electronic and software designs is employed for expanding sensor capability. Self-integration, configuration, data computation from the sensor, analog-to-digital data conversion and data processing relative to configuration options are investigated. Based on the approach proposed, an embedded sensor-system, consisting of a network of microcontrollers and sensors capable to respond to configurability and fast integrability requirements, is built and tested within this research. Tests have shown the smart sensor-system is functional, feasible, cost-effective, easy-to-use and highly reconfigurable. Integration of such sensors within reconfigurable, autonomous and distributed manufacturing systems is thus possible.

Study Designs

By using image processing and automatic control technologies, this study designs an unmanned ground vehicle (UGV) that can be operated by various control devices, such as laptops and joysticks. A camera is set up on the UGV to capture the sight around it, and then can send the video to the back end system in a wireless manner. Besides, we design an attacking system that allows users to do the zeroing correction for shooting the target precisely. Moreover, a shooting training system is designed to improve the convenience for target practice. It not only can send the result to the back end system immediately but also can simulate the enemy movement to make the training more reality.

The paper analyzes variations in the temperature of axle-box heating of railroad rolling stock considering two modes of the train - driving and parking position. Additionally, the article describes the influence of the axle load and season on the heat of the axle-box, forecasts intolerable residual resources and explains a possibility of detecting likely breakage at the very beginning of defects. The paper also deals with scientific literature related to axle-box heating and focuses on the conducted practical and theoretical experiments. The carried out research has established the rates of operating heating and critical heating. The application of numerical values for the algorithm of automatic control devices could help with detecting the breakdowns of the axle-box before they reach a critical state and assist in forecasting residual operating resources. Santrauka Nagrinėjama geležinkelio riedmenų ašidėžių kaitimo kitimas traukinio važiavimo ir stovėjimo metu, riedmenų krovumo ir metų laiko įtaka ašidėžei kaisti, neleistinai kaistančios ašidėžės liekamojo resurso prognozė, ašidėžės gedimo nustatymo galimybė pačioje gedimo atsiradimo pradžioje. Išanalizuota mokslinė literatūra, susijusi su riedmenų ašidėžių kaitimu, taip pat išanalizuoti atlikti eksperimentiniai ir teoriniai darbai. Tyrimo metu nustatytos ašidėžių darbinės ir kritinės riedmenų ašidėžių kaitimo temperatūros. Šių temperatūrų skaitines reikšmes pritaikius riedmenų automatinės kontrolės prietaisų algoritmui būtų galima aptikti ašidėžių gedimus, kol jie nepasiekė kritinės būklės, ir prognozuoti liekamąjį darbo resursą.
