The existing literature on eco-labeling and green consumerism has been framed within a classical market context where price and quality are the drivers of consumer choice. However, it seems possible that consumers are also concerned about the choices made by other consumers. In fact, it is unclear that people's consumption decisions are made independently of social context. For instance, under the
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
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
We present a stochastic path integral method to calculate the full-counting statistics of conductors with energy conserving dephasing probes and dissipative voltage probes. The approach is explained for the experimentally important case of a Mach-Zehnder interferometer, but is easily generalized to more complicated setups. For all geometries where dephasing may be modeled by a single one-channel d
A way to use adiabatic radiofrequency pulses and modulated magnetic-field gradient pulses, together constituting a "shim pulse," for NMR spectroscopy and imaging is demonstrated. These pulses capitalize on phase shifts derived from probe gradient coils to compensate for nonlinear intrinsic main magnetic field homogeneity for spectroscopy, as well as for deviations from linear gradients for imaging
A Surprisingly high degree of structural and compositional dynamics is observed in the system LiBH4-LiCl as a function of temperature and time. Rietveld refinement of synchrotron radiation powder X-ray diffraction (SR-PXD) data reveals that Cl- readily substitutes for BH4- in the Structure of LiBH4. Prolonged heating a sample of LiBH4-LiCl (1:1 molar ratio) above the phase transition temperature a
Nanovials, microarrays, and microfluidics are brought together for the exploration of complex biological problems.
We propose that the mechanical property of the interface between an implant and its surrounding tissues is critical for the host response and the performance of the device. The interfacial mechanics depends on several different factors related to the physical shape of the device and its surface as well as properties of the host tissue and the loading conditions of the device and surrounding tissue
The problem of recovering scene structure and camera motion from images has a number of inherent ambiguities. In this paper, configurations of points and cameras are analyzed for which the image points alone are insufficient to recover the scene geometry uniquely. Such configurations are said to be critical. For two views, it is well-known that a configuration is critical only if the two camera ce
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
