Hum and whistle not infrequently occur how can detect noise and remove it. Poor boxes are not always the cause, often it is simply a disorder that you can eliminate. You hear a faint beep or even annoying whistling sometimes that comes from your PC speakers? Starts the pipes as soon as you turn on your speakers? It occurs only if you turn up the volume? These are typical scenarios, but not always the loudspeakers are responsible. To remove noise, the cause must be found first. Install the latest sound driver noise are often caused by the wrong software. Before you search for mechanical causes, you should first ensure that you have installed the latest sound driver speakers and of course your soundcard for your PC. Only if the problem still occurs after updating, defect to a hardware or be considered a disorder. Unfortunately relatively common noises cause bad speaker.

Among other things, it’s not adequately shielded. What is boxing for the PC with the purchase of sound, you know. If you have but high-quality speakers connected to your PC, there must be an error. First, check whether the speakers are connected correctly and whether you use intact Plug and cable. A beep is sometimes caused when inferior cables in use are check leads and connections.

Also a not well insulated jack plug may cause noise. When you hear the whistle, touch the cables and connectors. Changed the tone or volume, is already found the cause here. In this case, it helps to replace cable or plug. If that doesn’t help, check the connections of your sound chip or sound card. Is the chip in the motherboard correctly screwed? If you the cause of the annoying sound still not find have, you should disable the onboard sound in the BIOS and test a separate sound card. It is simple but, to connect headphones, because when the computer hardware is causing the problem, the error even over headphones must be heard. Noise can be but also to additional devices are operated at the same time with the boxes or hang just on the computer. Often, a sound could be eliminated simply by pulling out from microphone or headset. In this case, there is a feedback of the culprit. Last but not least, you should check the PSU also, because power supplies can also cause noise from PC boxes. Humming speakers the so-called ground loop is a typical problem that can occur with speakers to the PC. Often speakers begin to hum, if if you connect a TV USB stick or a TV card. Devices with different ground connections are used, may cause a disturbance in the signal line. This disorder is at Listen to speakers as a buzzing sound. A sheath current filter as intermediate connector for the antenna cable, you can buy ten euro in the trade already for about a remedy here. If you can exclude all these factors, may be but a defect on the PC is speakers, so these should must be returned or exchanged within the warranty period. Eva Otter

Plant construction software for renewable energy on the NextGen 2013 Moers, Germany 21 November 2013: the promotion of renewable energy with affordable engineering software projects is at CAD Schroer atop the agenda. The CAD-software provider presented its latest developments in March at Biogaz Europe, in April on the sustainability live and in October on the NextGen 2013. For eco-friendly plants and factories, the worldwide environmental awareness drives local politics and the use of new environmentally friendly technologies for a more efficient utilization of renewable energy sources. Combined with combined heat and power biomass, anaerobic digestion and bio waste electricity generation (EFW) were the focus of many energy conferences this year,”says Anke Adams by CAD Schroer UK. We took part in the conferences, to help the profitability in the planning and execution of engineering projects in the field of renewable energies more efficiently to make.” CAD schroer group presented its 3D-Anlagenbau-Software, the it project engineers enables systems to plan whatever size, with engaging full supply techniques and to create cost estimates for brownfield – or greenfield projects quickly.

Companies that use MPDS4 for projects in the field of alternative and renewable energies, receive a 70% discount on the software of CAD Schroer. Also the maintenance and support are offered similarly beneficial. MPDS4 demo videos: produkte/mpds4/anlagenbau.html MPDS4 for renewable energy: produkte/mpds4/mpds4-aktion-fuer-alternative-und-erneuerbare-energien.html comprehensively informed about renewable energy visitors of the NextGen 2013 could with a challenging and diverse Conference programme in detail about energy efficiency, reduction of carbon dioxide emissions and financing, planning, preparation and operation of supply systems for energy generation from renewable energy sources inform themselves. Speakers on four different stages concentrated on small systems such as biomass or Power heat cogeneration plants in urban areas in the immediate vicinity of the consumer. The sections of the Conference brought visitors with topics such as current legislation and industry analysis on the cutting edge. We are pleased that we can contribute to the sustainability debate with our software and our expertise, as well as the technology that makes the system planning as productive and profitable as possible,”so Anke Adams.

FLS: Trends of production planning for 2014 Eschweiler, 3rd December 2013 FLS offers views on trends and challenges developments in the area of production planning and control (PPC) for the year 2014: the variety of products is rising due to the change in consumer behavior. Companies are challenged to improve processes in order to secure the pool position prior to the competition. Because anyone who can deliver more reliable and cheaper, especially with shortages. According to FLS, systems (MES) in the manufacturing industry, a provider of software for manufacturing execution manufacturing companies with following developments and challenges faced: manufacturing companies are under increasing pressure to meet the demand and the needs of their customers. They expect constant readiness in an increasingly changing assortment and decreasing quantities per article. This can be measured particularly at times of high demand, such as E.g. a heat wave in the summer, an early onset of winter, or even seasonal events in the year.

The production can’t then with conventional planning, on short-term contracts, changes, fast enough to respond to bottlenecks or outages. Companies must be flexible in your production and yet continue to cost effectively produce, to remain competitive. A production planning optimization must be at the top on the priority list. Following trends for production planning are: 1. increasing of productive hours setup time optimization.

The high times and set-up costs offer savings in production planning. These are caused through the conversion of the machines and thus connected standstill of production facilities and high personnel costs. The focus of the production planning is the calculation and reduction of set-up time and cost. It aims to avoid the costly setup, waiting and waiting times through a meaningful sequence planning. Use a matrix of set-up time is unsuitable because the first level and the subsequent care with a high effort, are connected. After a relatively short time can be traced barely, as the individual values are reached.

Stuttgart the database connection HSDBASE by HS automation software can production data from Siemens S7 control systems now also in QDAS ASCII transfer format drop. HSDBASE must be configured simply now all production data without any additional programming effort can capture and recovery, for example, in qs-STAT. The configuration can be done independently by the PLC technician responsible for the system. In addition to QDAS, HSDBASE continues to support the database formats MySQL, CSV, access, MSSQL and Oracle. HSDBASE is the solution when it comes to data acquisition from S7 controllers.
