This paper presents a detailed description of a propagation channel measurement campaign performed in a warehouse environment and provide a comprehensive channel model for this environment. Using a vector network analyzer (VNA), we explored both Line-of-sight(LOS) and Non-Line-of-sight (NLOS) scenarios over a 2-8 GHz frequency range. We extracted both small-scale and large-scale channel parameters

Biomechanical models which require information on, e.g., joint torque and muscle force are useful in the estimation of when and how mechanical overload of the musculoskeletal system may lead to disorders. The aim was to study the reliability and validity of magnetic resonance imaging (MRI) to quantify muscle sizes and moment arms by MRI and to test selected anthropometric measures as predictors of

Among the science challenges of the Extremely Large Telescopes (ELTs),four object types are studied for performance with a 50 m ELT withadaptive optics (AO), Euro50. Emphasis is on planetary systems and verydistant objects. For planetary systems and their evolution, we examinehigh resolution imaging of the nuclei of comets and high-resolutionimaging, photometry and low and intermediate resolution

Packaging has a significant impact on the efficiency of logistical systems and therefore, improvements in the retail supply chain can be achieved through the integration and development of the systems of packaging and logistics. In order to enable these improvements, models are needed that facilitate evaluations along the supply chain in order to grasp the whole picture and avoid sub-optimisations

By the autumn of 1966, the PRC government had enjoyed seventeen years of uninterrupted and complete domestic information dominance. Independent collection of information was hampered by way of a CCP culture of secrecy and successfully enforced regimen of information curtailment. Of the changes in the political landscape triggered by Mao Zedong’s August 1966 decision to label part of government off

Kan man göra sig en bild av Gud? För de första kristna som levde i en värld fylld av gudabilder var frågan mycket konkret. Trycket från omvärlden på att namnge och synligt presentera den kristne guden var starkt. Men hur skulle man kunna avbilda den som intet öga sett, den som inte låter sig avbildas? Hur tala om den som inget öra hört, den som är ofattbar? De här samlade artiklarna från det sjätt

It has been predicted theoretically that for some environments, the capacity of wireless MIMO systems can become very low, even for uncorrelated signals; this effect has been termed "keyhole" or "pinhole". We present the first unique measurements of this effect. The measurements were performed in a controlled indoor environment that was designed to obtain a keyhole. We analyze the limitations for
