The most common PID design methods in industry are based on formulas. This article will present some major advantages of instead using the power of computer based softwares for PID controller design. The Matlab based software used in this work was developed in 2007 and derives robust, IAE minimizing, PID controllers. The experiences of using this software are collected in this article and include
Internet of things technologies makes it possible to trace when and where the excellent food or wine is spoiled or loses perfect taste in logistics and retail. This paper describes a system using a two-layered wireless sensor network to monitor the supply chain from manufacturer to consumer, including the network topology, application software on server, and sensor node hardware. It employs GSM/GP
Reliable analytical methods are increasingly needed in the food and beverage industry for the determination of specific components (e.g. sugars, proteins, vitamins, fats) and for detecting and quantifying chemical contaminants such as pesticides, heavy metals, antibiotics, and pathogenic microorganisms. The need arises from numerous regulatory actions and increased consumer concern about food comp
Stochastic processes are indispensable tools for development and research in signal and image processing, automatic control, oceanography, structural reliability, environmetrics, climatology, econometrics, and many other areas of science and engineering. Suitable for a one-semester course, Stationary Stochastic Processes for Scientists and Engineers teaches students how to use these processes effi
The influence of supranational regimes has dramatically increased in the last decades. How this influence is manifested and which consequences it has had and continues to have on education is discussed in this paper. More specifically, the paper highlights lifelong learning and the Bologna process seen as projects, the explicit aims of which starkly contrast to their effects on such vital issues a
Popular Abstract in Swedish Denna avhandling beskriver tillverkning av partiklar av metaller och halvledare samt dessas användning i nya typer av elektroniska komponenter och nanostrukturer. Partiklarna tillverkas med aerosolteknik, dels med kända metoder och dels med nyutvecklade. Partiklarna är mellan 5 och 80 nanometer (miljarddels meter) i diameter, och deras bildning, struktur och sammansättnAerosol technology was used to develop new methods for fabrication of size-selected, nanometer-sized particles of metals and semiconductors. Such particles were used to realize different types of quantum devices and nanometer-sized structures. The thesis contains an introduction, five papers on particle fabrication, and five papers on particle-based quantum devices. Size-selected gallium and indi
With a new surgical instrument, a haemostatic dissecting tool driven by ultrasonic energy, different surgical procedures is described within the neck, the chest, and abdomen both for open and laparo- and thoracoscopic procedures. Also orthopedic procedures are described. I also wrote the chapter 5: Esophageal resection with the Ultracision blade and shears.
In recent years, there has been growing interest in stabilized index reduction techniques for differential-algebraic equations (DAE) of multibody dynamics. A number of the proposals which incorporate the idea of a projection onto the constraint manifold are discussed. The methods are divided into classes based on whether the projection is performed on the residuals of the discretized DAE or on the
Fuel cells are promising for future energy systems, since they are energy efficient and, when hydrogen is used as fuel, there are no emissions of greenhouse gases. Fuel cells have during recent years various improvements, however the technology is still in the early phases of development, this can be noted by the lack of dominant design both for singe fuel cells, stacks and for entire fuel cell sy
We consider construction and realization aspects of encoders and decoders for braided block codes (BBCs), which are a powerful class of iteratively decodable codes. An efficient encoder is proposed as well as a pipeline decoder realization. Also, upper and lower bounds on the free distance of BBCs are derived.
