The meaning of the word cavitation is not known or understandable for many people. The definition which is commonly known about such phenomena is that the formation of cavities or bubbles is encouraged by a pressure change in the surroundings. However, cavitation is much more complex. A large amount of research work and studies on the dynamics of the cavitation phenomenon via numerical investigati

Introduction Many kinds of footwear are used for various purposes in the workplace in Japan. Careful selection of footwear is needed to protect workers from coldness and to keep the performance of workers in cold workplace where employees have to work under -20℃. On the other hand, safety boots with high heat conductivity from foot to outside are needed for the workers in hot environments. But the

This study offers a method for empirically testing theories operationalized in the form of multivariate statistical models. An innovation of the method is that it distinguishes testing into three separate forms, “effect testing,” “prediction testing,” and “theory testing,”where statistical significance plays a separate role in each one. In another innovation, the researcher specifies not only his

Since the 1980’s, additive manufacturing (AM) has gradually advanced from rapid prototyping applications towards fabricating end consumer products. Many small companies may prefer accessing AM technologies through service providers offering production services as result-oriented Industrial Product-Service System (IPSS) rather than investing in their own production line. This study investigated pot

A thoracic phantom, with embedded fragments of uranium (U) and iron (Fe) of different sizes, was imaged with digital radiography, standard-dose CT and low-dose CT and the detectable size of the fragments was recorded. U and Fe fragments were detected in diameters down to 100 mu m and 300 mu m, respectively with the standard-dose CT and digital radiography. The size limit using the low-dose CT was

This paper is intended to give an overview of the current work of the International Commission on Radiological Protection (ICRP) within the field of medicine and healthcare. The paper focuses on the work carried out in Committee 3. Some views expressed at the ICRP Seminar in Bethesda, USA in October 2011 will also be discussed. Similar and complementary work by other organisatons will also be brie

Radiochromic film, polymer gel and radiochromic plastic are three different kinds of dosimeters developed for radiation therapy and suitable for optical readout. In this study, different optical CT scanners are used to scan the dosimeters to find out if they could be used as multi-purpose scanners, i.e. for readout of the different kinds of dosimeters. Promising results are found but further devel

The extent to which in-situ global mechanical tensioning (GMT) can be used to modify the residual stress state in friction stir (FS) welds is investigated in this article. Residual stress distributions have been determined by synchrotron X-ray and neutron diffraction for four sets of FS welds in high-strength AA7449-W51 and lithium containing AA2199-T8 aerospace aluminum alloys subjected to a syst

Most works published on iterative CDMA receivers assume perfect channel knowledge or very simple channel models like the flat-fading channel. We want to extend the scope to multipath propagation scenarios and suggest an iterative scheme with channel estimation in the uplink of a chip-synchronous CDMA system. Channel estimates rely on pilot symbols and a posteriori probabilities on code bits of a S

A major concern for contemporary organizations is how to gain support of business processes from standardized software package such as enterprise resource planning (ERP) systems. To gain support adoption of such standardized information and communication technologies (ICTs) demands that either the system is adjusted to existing business processes or that business processes are adjusted to the syst

Laktos – astmamedicinens bästa vän? Att leverera medicin till lungan är en krånglig process då en stor del av den verksamma substansen riskerar att fastna i svalget. Ny forskning har dock gett bredare förståelse för hur små partiklar av laktos kan användas till att öka effektiviteten hos inhalerbara läkemedel. Vid behandling av sjukdomar som drabbar luftvägarna, så som astma, finns det olika sätA common approach to treat respiratory diseases is with adhesive powder mixtures. These are dispersed into an aerosol upon inhalation. It has been found that the performance of such mixtures can be improved by adding fine particle lactose, but exactly why is yet to be established. Several theories have been proposed by previous studies, but the fundamental mechanism is still unknown. This study w

This study investigates the integration of Large Language Models with the TRIZ to improve problem solving and innovation in industrial product development. By combining the structured problem-solving framework of TRIZ with LLMs to process large amounts of data and generate ideas, this hybrid approach seeks to overcome the limitations of traditional TRIZ and optimize solution generation. In a case

LIDAR techniques have been extensively used for studies of aerosol particles. Fluorescence LIDAR was employed for studying natural bio aerosols, such as pollen, but also possible warfare agents. Insects, being "large aerosol" particles clearly give rise to LIDAR returns. Recently, honey bees were studied by polarization reflectance LIDAR and their superior olfactory abilities were used in attempts

Jorunn Joiner and Mari Komnæs also employ digital tools, albeit other ones, to shed light on the interaction between narratives of exceptionalism, travel, and place. In ‘Mapping Nordic Exceptionalism with GIS: The Odin Migration Theory and the Search for a Northern Heritage’, they use digital mapping tools to visualise the journeys of two travellers from different centuries in their search for a N
