Intelligent vehicle control based on identification of road signs by solar po...eSAT Journals
This document proposes using solar-powered RFID technology to automatically control vehicle speeds based on road signs. An RFID reader in the vehicle detects the speed limit from an active RFID tag attached to a sign. This reference speed and the vehicle's actual speed, measured by a sensor, are inputs to an electronic control unit. The ECU then controls the vehicle's speed through two proposed methods - adjusting the fuel pump to reduce fuel intake, or activating an electro-hydraulic braking system. This system aims to reduce traffic violations by automatically enforcing speed limits without needing infrastructure in rural areas, as the signs are solar powered.
Scheduling for interference mitigation using enhanced intercell interference ...eSAT Journals
Abstract Deployment of low power base station (pico) in macro cell is a key for providing high data rates. Cell range expansion is one of the features of LTE-advanced where low power base station in a heterogeneous network can increase their coverage area and neighboring cells can offload users to low power base station to reduce overload in macro cell. This presents a very challenging multi-user communication problem. Co-channel deployed Het-Net will experience interference between pico and macro. The main challenge of pico cells embedded into a macro cell is to let more users profit from the additional bandwidth introduced into the network. Enhanced Inter-cell Interference Coordination (eICIC) has been introduced to solve interference problem. Scheduling for eICIC is used to provide best solution for interference mitigation, overload in macro cell, fairness in resource usage by users. In this paper we have analyzed Round Robin scheduling for eICIC, results prove that fairness is maintained between users and throughput has been improved. Key Words: LTE - Long term Evolution, UE - User Equipment, eNB – eNodeB.

The document proposes a new "bound and decomposition method" to find an optimal fuzzy solution for fully fuzzy linear programming problems. The method decomposes the given fully fuzzy linear programming problem into three crisp linear programming problems: a middle level problem, upper level problem, and lower level problem. The three crisp linear programming problems are then solved separately. Using the optimal solutions from these problems, an optimal fuzzy solution for the original fully fuzzy linear programming problem is obtained. The proposed method does not require fuzzy ranking functions or restrictions on the coefficients matrix elements.
This document summarizes a study that analyzed the physicochemical properties of clay mineral from Nteje, Nigeria after activation with sulfuric acid. The clay was treated with sulfuric acid at concentrations ranging from 2-7 mol/L. Characterization showed acid activation modified the chemical composition by exchanging octahedral cations for hydrogen ions, altering the crystalline structure and increasing surface area over three times that of the raw sample. Bleaching tests using the activated clays showed adsorption capacity and color removal from palm oil increased, with the 6 mol/L activated clay achieving 92.5% removal compared to 43.4% for the raw clay. The results indicate acid activation enhanced the adsorptive properties of the Nte
