The main objective of this project is to develop a Home automation system using an Arduino board with Bluetooth being remotely controlled by any android OS smart phone. As technology is advancing so houses are also getting smarter. Modern houses are gradually shifting from conventional switches to centralized control system, Involving remote control switches. Presently, conventional wall switches located in different parts of the houses makes it difficult for the user to go near them to operate. Even more it becomes more difficult for the elderly or physically handicapped people to do so. Remote controlled home automation system provides a most modern solution with smart phone. In order to achieve this, Bluetooth module is interfaced to Arduino board at the receiver end while on the transmitter end, a GUI application on the cell phone sends ON/OFF, commands receiver where loads are connected. By touching the specified location on the GUI a prompt will appear which will seek a command. Thus switching ON/OFF the connected loads.

Purpose This paper aims to propose a spreadsheet method for modeling and simulation of a retraction system mechanism for the retractable self-launching system for a high-performance glider. Design/methodology/approach More precisely, the method is based on parametric link design using Excel spreadsheets. Findings This method can be used for kinematic and dynamic analysis, graphical plotting and allows simulation of control kinematics with the ability to make quick and easy parametric changes to a design. It also has the ability to calculate the loads imposed on each component in the control system as a function of input loads and position. Practical implications This paper shows that it is possible to model complex control systems quickly and easily using spreadsheet programs already owned by most small companies. The spreadsheet model is a parametric model, and it gives a simple visual presentation of the control system with interactive movement and control by the user. Originality/value This spreadsheet model in conjunction with a simple CAD program enables the rapid and cost-effective development of control system components.

Installed Capacity

New locations for onshore technology, which have not been considered so far, must be developed to increase the total installed capacity of renewable energies, especially wind energy. For this purpose, cost-effective wind turbines, even in difficult-to-access locations, such as mountainous and high-mountainous areas, must be designed. This paper presents a novel wind turbine with a related control system that meets these requirements. The proposed turbine uses a multi-rotor configuration with five rotors arranged in a star shape configuration. Each rotor drive train combines up to 12 generators in a maintenance-friendly multi-generator concept. A suitable observer-based control for load mitigation in the full-load region is proposed for the multi-rotor and multi-generator design. Simulations are used to demonstrate the applicability and practical benefits of this concept.

Abstract There are a number of systems on an aircraft working together, in harmony, to produce safe and trouble free flight. The environmental control system (ECS) is one of these systems, and its failure is a major contributor to unscheduled maintenance, particularly in older aircraft. The ECS is composed of several complex sub-systems and components, but at its heart is the passenger air conditioner (PACK). The PACK is prone to degradation, which can lead to the functional failure of the ECS. Often its degradation is masked by the overall ECS control system and this can, ultimately, result in the ECS shutting down and extensive maintenance being required. There are a number of critical fault modes associated with the PACK, and in this paper, those modes associated with the primary and secondary heat exchangers (SHX) are explored. A robust ECS simulation framework called Simscape ECS simulation under all conditions (SESAC) has previously been implemented, calibrated, and tested against data from healthy systems. Here the simulations are extended to cover degraded components in a representative Boeing 737-800 aircraft PACK model. Fault modes such as blockage and fouling are assessed for the primary and secondary heat exchangers of the PACK. Simulation results, in terms of temperature, pressure, and mass flow at various degradation severities, are presented and discussed. The results highlight the interdependency between the PACK components and the strong association between the primary and secondary heat exchangers performance. The reported simulation methodology and findings serve as a further step towards the goal of formulating a cost-effective ECS fault isolation and diagnostic solution.

A small general-purpose teleoperated hydraulic mobile machine is studied at the Institute of Hydraulics and Automation at the Tampere University of Technology. Thanks to teleoperation, the operator of the machine is able to be in safe place during the driving when necessary. However, the actions of the machine can be dangerous for the people or the objects in the environment if problems appear for instance in the control system. On that account, safety issues must be considered carefully. Special attention has to be paid to stop the machine and start the engine again once the machine has recovered from an error situation. The goal of this paper is to describe the design and implementation of different kind of solutions to start and stop the machine wirelessly. The emergency stop can be activated through the wireless connection by the operator or by the automatic diagnostic system of the hydraulic mobile machine. The control system monitors the state of several hydraulic components such as hydraulic valves and motors by means of sensors during the operations of machine. The machine is teleoperated by using WLAN (Wireless Local Area Network) connection. The developed wireless starting system and emergency stop is totally independent of the WLAN link. In the first prototype of the wireless starting system and emergency stop, the wireless connection is carried out by using commercial, cost effective RF (Radio Frequency) modules. The data transfer protocol which is used by the modules is designed for this application. Protocol implementation is carried out with microcontrollers. Another version of the wireless starting system and emergency stop is carried out by using radio modems. The modems have better properties than the cost effective RF modules used in the first prototype due to their higher RF output power. Programmatically carried out automatic emergency stop, which stops the machine, if the WLAN connection between the control station and the machine breaks, is discussed. In that case, the independent wireless emergency stop connection is not needed. Implementations of the system are introduced in this paper. Also, some testing results and user experiences are described. Properties of these different implementations are compared: cost of the system, range, reliability and complexity of the implementation. By means of the studied results the most suitable solution to start the engine and stop the actions of the machine is chosen.
