Structural investigations of compounds in the CsI-(Cd/Hg)I2 system have been performed by means of X-ray diffraction, thermogravimetric and calorimetric techniques. Crystals of the compounds studied were synthesized from aqueous solutions of CsI and CdI2/HgI2 by the slow evaporation of water. In total, the structure of ten compounds were determined by means of X-ray diffraction on single crystals,
It is essential to find suitable modes (combinations of alphabet sizes and code rates) for transmission in cellular systems. Bad choices result in low spectrum efficiency. An analytical method is proposed to find the modes which give the highest spectrum efficiency when using adaptive modulation. It is demonstrated that data rates considerably higher than 271 and 384 kbps are feasible in GSM and E
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
Popular Abstract in Swedish Varför är vissa individer bättre på att identifiera och exploatera nya affärsmöjligheter än andra? Ett antagande som ofta lyfts fram är att framgångsrika entreprenörer förväntas ha utvecklat specifika kunskaper genom tidigare karriärerfarenhet, vilket i sin tur främjar deras entreprenörskap. Om detta antagande stämmer, hur kan vi förstå denna erfarenhetsbaserade lärprocWhy are some individuals more successful in recognizing and exploiting new venture opportunities than others? The common view is that successful entrepreneurs have acquired and developed specific types of knowledge through their previous career experiences, which in turn facilitate their involvement in the entrepreneurial process from opportunity recognition to opportunity exploitation. If this is
The purpose of this work is the enhancement of performance by a new design of monolithic heat exchangers under steady-state operating conditions. Heat transfer phenomena and hydrodynamics have been studied and visualized by computational fluid dynamics (CFD). Further, a simple gas distribution system has been analyzed in purpose to find the best performance of the exchanger. To achieve this, 3D si

Stem Cell travel refers to patients with a variety of diseases and debilitating disorders who travel abroad to receive unproven stem cell treatments. Current academic research investigating how to combat stem cell travel has yet to offer a complete understanding of the link between patient hope and autonomy, and building or losing trust in medical authorities. To combat stem cell travel, understan

Electronic commerce (E-commerce) is one of the issues that are expected to influence the various logistics and supply chain processes/operations including: production, packaging, warehousing, transportation, etc. Consequently, the environmental implications of E-commerce are of concern and interest. In this regard, there are some pilot studies, but they are unable to deliver conclusions or general
