...Hydrogen Concentration Sensor Selection for the Renewable Energy Vehicle Travis Hydzik School of Mechanical Engineering, The University of Western Australia Associate Professor James Trevelyan School of Mechanical Engineering, The University of Western Australia ABSTRACT: This paper discusses the selection of a hydrogen concentration sensor for the use in the University of Western Australia’s Renewable Energy Vehicle (REV). Prior to selecting a sensor, it is important to consider the available sensing methods and the specific properties of the measurand, hydrogen. The selection process leading up to the purchase of two different hydrogen sensors from Neodym Technologies, is documented and finally the method of sensor calibration is outlined. 1 INTRODUCTION The University of Western Australia’s Renewable Energy Vehicle (REV) project aims to show the viability of using renewable energy as a means of transport. The vehicle will resemble the cars of today, but will be solely powered by a hybrid of hydrogen fuel and solar energy. The proposed car’s completion date is late 2005, allowing it to be driven around Australia in 2006. The REV requires numerous amounts of measured physical quantities for both data logging and controlling the car’s systems. For each measured physical quantity, a sensor is required to convert this quantity into an electrical signal. Safety is always first priority, and for this reason hydrogen leak safety sensors were given the highest priority on...

De los tipos de sensores que más llaman la atención, se destacan los sensores de luz, y entre ellos los conocidos Infrarrojos, y a ellos le dedicaremos este artículo... Para hacer una breve descripción de lo que es una radiación infrarroja, imagínate la luz del sol, pues esta contiene todas las bandas de colores con las cuales se compone la luz blanca (conocido como espectro de emisión de luz), ahora, en los extremos del espectro se encuentra la radiación infrarroja (IR) y la ultravioleta (UV), ambas son imposibles de ver, es decir son invisibles, pero estan presentes y nosotros las vamos a poner en evidencia... En microbótica tanto como en robótica, se hace uso de este tipo de emisión de luz (en especial la infrarroja) con la intensión de detectar obstáculos sin que uno de nuestros modelos tome contacto físico con el mismo. En algunos casos una vez establecida la comunicación entre emisor y receptor, es posible realizar una transmisión de datos, sino imagínate... como hago para aumentar el volúmen de mi TV, cambiar de canal, aumentar el brillo, quitarle el color..., etc., etc., y todo con un sólo emisor de IR...??? Pero bueno, sólo les mostraré lo básico, y cuando aprenda más les comentaré al respecto. Existen encapsulados que traen incorporado en su interior tanto al emisor como receptor, de todos ellos, el más conocido...

... 3. Current UTC Systems in South Africa 3.1 Remote Monitoring Systems Remote Monitoring Systems (RMS) are traffic control systems that connect a roadside controller to a central computer to provide a remote monitoring facility at the traffic signal equipment. RMS offers functionality that allows it to monitor digital inputs and outputs, phase outputs and phase lamp monitoring. In the occurrence of any faults, the system connects to the in-station, alerts the operator and lodges the fault simultaneously (Imtech Traffic and Infrastructure UIC Ltd). In addition, these systems offer a range of other features such as traffic data collection, remote clock setting and loading of signal plan configurations. Communication between the roadside controller and the central operator is via Public Telephone Network (PTN). 3.2 UTC Systems These systems provide direct control of the traffic signal at an intersection from a central computer. The central computer manages stage timings, plan changes and auxiliary monitoring functions while safety functions such as minimum stage lengths are controlled by the roadside controller. Compared to the RMS, central computers of UTC systems provide immediate and direct control of signal timings, as well as generate and initiate new signal timing plans. This offers significant speed advantage in any unplanned event. UTC systems also offer full monitoring facilities along with traffic flow enhancing facilities such as Traffic Responsive Plan Selection (TRPS)...

...F.A.Q for smcFanControl 2.4 How do install and uninstall smcFanControl? smcFanControl is just an application. So after downloading, and unzipping it, drag it to wherever you want (e.g. the Application Folder). To uninstall it, just drag it into the trash. smcFanControl installs no permanent background processes or daemons. All changes smcFanControl does to the fan controlling get lost after you shutdown your computer (power off, not restart) or enter standby mode (as far as you don't have smcFanControl running) . Minimum fan speed then falls back to the system defaults values. When I run smcFanControl and set a new minimum speed, will my fan speed still increase if the CPU load gets higher? Yes, fan speed will increase as defined by Apple. smcFanControl lets the fans stay in automatic mode and just sets the minimum fan speed. However, the higher you set the minimum fan speed, the longer it will take for the fan speed to increase. Why does smcFanControl asks for a login and password and which login/password do I have to enter? smcFanControl needs the credentials of an admin-user to set the appropriate rights to be able to change fanspeed. You only have to enter it one time. The entered login and password are not saved by smcFanControl. They are just used for setting the appropriate rights. I get a "smcFanControl has not been tested on this machine" warning. What does that mean? Technically smcFanControl supports every intel mac, but it does not come with defaults...

...Advances In Medical Technology: What Does The Future Hold? ScienceDaily (June 16, 2009) — Major challenges and opportunities will arise in the health sector in the future. Research in technology that can be applied to this sector is being carried out by several UPC teams. [pic] Although sophisticated medical technology is already available in health systems in developed countries, further advances are constantly being made. As a result of the addition of medical nanotechnology to existing knowledge of molecular and cellular biology, it seems likely that new, more personalised, more accurate and more rapid diagnostic techniques will be devised in the future, as well as new treatments that are also more personalised and promote regeneration of the organism. Clearly, as areas of research such as biomaterials or tissue engineering are developed for use in regenerative medicine, the range of opportunities will increase dramatically. Josep Anton Planell, the director of the Institute for Bioengineering of Catalonia (IBEC), which was formed by the UB, the UPC and the Generalitat (Government of Catalonia) and has its headquarters in Barcelona Science Park, considers that “in the future, it will be possible to design intelligent biomaterials that, when placed where damaged tissue needs to be regenerated, will be able to stimulate the stem cells to do what we want them to do”. However, more knowledge is needed to perfect the process. He states, “We are beginning to understand which...

...Introduction The evolution of autonomous robots has inspired competitions worldwide, including the most notorious Micromouse Competition. This competition has existed for over 30 years in the United States and hasn’t changed much since the beginning. The goal is simple: the robot must navigate from one corner to the center as fast as possible. The actual final score is comprised of the total time in the maze and the time of the fastest run. The various components include techniques to streamline the methodology and make a proficient automated robot. Maze Solving Strategy The maze solving strategy is comprised of an algorithm. An algorithm is a step-by-step problem-solving procedure, especially an established, recursive computational procedure for solving a problem in a finite number of steps. The implementation The Group chose was a revised version of the bellman flooding algorithm. The algorithm requires around 256 X 3 bytes of memory. The selected microcontroller for implementation had only 256 KB of memory. We need to use software that has exceptional amounts of RAM and ROM memories. To solve the whole maze you will need to set the starting cell to the first cell in the maze. If you want to reverse the path traveled by the robot then you would set the target to the first cell, and the starting cell would then be the center or your current location. The problem statement has been simplified to three rules which we will follow to direct our robot to the center of the maze...

...IoT (Hiremath, 2015) IoT stands for Internet of things which in itself explains that it is things that are connected to internet which include sensors, devices, actuators, transducers any equipment or material thing (further referred as THINGS ) which in some way are able to communicate via internet. There has been some kind of automation in industry, home, and office through various THINGS but IoT is a concept where in all these THINGS are connected to internet and communicate via internet and can be intervened or controlled through internet. They also intern generate data and can be stored on cloud for further processing or the data required for control mechanism of these THINGS may exist on cloud itself. The crux of such exercise is to achieve improved efficiency, effectiveness, accuracy and economic benefit. I chose not to tell you the whole story but few specific examples of IoT which will bring us on same page of thoughts and make us easily understand in future anything we come across which is related to IoT. Smart Home: Smart home widely working on ZigBee protocol (considered as most secured and safe till now) is basically automation of lights, AC, door lock, Curtains etc.. In home and also able to communicate via internet through a gateway to any smart device connected to internet like smart phone and be accessible to any authorised user so as to monitor or control home appliances sitting globally anywhere using a smart home specific application.
