This paper presents a modified numerical model for Elastohydrodynamic lubrication (EHL) calculations of involute spur gears. This model considers the fluid as a Newtonian fluid. The main study performs on gear EHL properties along path of contact (POC). Using this study, the minimum film thickness and maximum pressure value as well complete film geometry and pressure distribution could be obtained for various applicable purposes. This study also uses a full numerical model for both gear load calculations and EHL calculations instead of experimental, approximation or analytical-experimental equations. Numerical method lets the model to calculate all required data without any limitations about the validity rang of experimental and analytical-experimental equations. In order to explain the process completely, paper firstly reviews a mathematical model to calculate the load distribution, single contact stiffness and meshing stiffness, transmission error and path of contact under load without using finite element method and in shortest time. Then a numerical method presented to solve the mathematical model using a double iteration flowchart to close the problem. This model is flexible to adapt for any modification in spur gear profile geometry. In addition to the gear load model, a modified and accelerated EHL numerical method reviewed to be utilized in this paper. The model for load distribution presents a realistic calculation for current study and modified EHL model helps to do calculations more exactly in shortest time. Finally the results of full model (that utilizes the two old models) will discuss and compared with previous methods.

Modern home telehealth care systems should support personalized data processing and environment monitoring for context awareness. Semantic rule based approach has been proposed by many authors to overcome problems coming from large amounts of location and patient-specific, typically inconsistent monitoring data. However, existing solutions just present proof of concept and do not address implementation feasibility and practical issues of eHealth system compatibility. We describe a telehealth care solution employing Prolog programs based on defeasible rule-based reasoning and SNOMED medical terminology system deployed in home digital TV receivers.

The object of this study was to understand precisely the acoustic vibration characteristics of the paulownia for musical instrument. Two paulownia chosen were Paulownia australis and Paulownia elongata, and compared with the picea (Far East Picea koraiensis and Picea jezoensis). The acoustic vibration parameters of four trees were respectively measured and comparative analyzed based on the vibration method of FFT by tapping, and then the acoustic vibration characteristics of paulownia were comprehensive evaluated. The results demonstrated that the density had nearly no effect on the loss angle tangents of the paulownia and the picea, and the loss angle tangents of four trees were similar. At the same time, the values of the specific Young's modulus and acoustic impedance of the paulownia were smaller than that of the picea, but the paulownia's acoustic radiation constants and the loudness were larger and higher than the picea's. It indicated that, according to all acoustic vibration parameters evaluated, the paulownia had the same good acoustic vibration characteristics with the picea, and the paulownia was suitable for wood for musical instrument.

In this paper, first a theoretical analysis for wind turbine and Double-Fed Induction Generator (DFIG) is processed, given the mathematical models of them. Aiming at the problems of the conventional PI controller, a Fuzzy-PI control strategy is presented. A comparison between the developed vector controller with the proposed Fuzzy-PI strategy and the same vector controller with a conventional PI strategy employing fixed gains has been done. The simulation results also show that using the proposed controller, the dynamic response of the system can be improved and more precise control is achieved.

Studies on temperature distribution during welding are very important because this may pave the way for application of microstructure modeling, thermal stress analysis, residual stress/distribution1 and welding process simulation. An attempt has been made in this paper to predict of temperature variation of entire plates during welding and after welding through an analytical solution is derived from the transient multi dimensional heat conduction of infinite plate to finite thickness. The heat input that is applied on the plate is exactly same amount of heat lost for electric arc is assumed to be a moving double central conicoidal heat source with Gaussian distribution for Submerged Arc Welding process. The prediction was compared with experimental results with generally good agreement.

Improvement in braking performance and vehicle stability can be achieved through the use of braking systems whose brake force distribution is variable. Electronic braking force distribution has an important and serious role in the vehicle stopping distance and stability. In this paper a new approach will be presented to achieve the braking force distribution strategy for articulated vehicles. For this purpose, the mathematical optimization process has been implemented. This strategy, defined as an innovative braking force distribution strategy, is based on the wheel slips. The simulation results illustrate proposed strategy can significantly improve the vehicle stability in curved braking for different levels of vehicle deceleration

Real-time monitoring of temperature has become crucial in cases like server room, incubators of infants in hospitals, coal mines, green houses etc. In all these cases we prefer a temperature sensor which ensures user's safety, proper alarming conditions, be simple to use (user friendly), easy calibrations, small and light weight, inexpensive and effective. The aim of this system is to provide an effective alert mechanism when the temperature of the scenario goes beyond a critical value. The temperature change in each instant of the surrounding is fed into the database and here it is processed by the pc, which monitors it. Then if the parameter goes beyond a critical value, which can be calibrated initially, an alarm is turned on in the room to give a primary warning to the person in-charge of the locality. If there is no adequate response and the temperature is allowed to rise, an SMS (Short Message Service) notification is given via wireless modem to the responsible person. An emergency call is also made to the responsible person via the wireless modem and a recorded voice is played. This way the alert mechanism reaches effectively to the concerned
