Close-to-Fourier heat conduction equation for solids: motivation and symbolic-numerical analysis

Heat conduction close-to-Fourier means, that we look for a minimal extension of heat conduction theory using the usual Fourier expression of the heat flux density and modifying that of the internal energy as minimal as possible by choosing the minimal state space. Applying Liu's procedure results in the class of materials and a differential equation both belonging to the close-to-Fourier case of heat conduction. A symbolic-numerical computing method is applied to approximate the numerical solutions of 2 special heat conduction equations belonging to the close-to-Fourier class

Risk perception and differences in self-reported cycling behavior between electric- and conventional-bike riders in Denmark

Electric bikes can contribute to the decrease of emissions and present a carbon-positive alternative to gaspowered forms of motorized transport. Hence, the fact that both conventional and e-bike use have increased considerably during the Covid-19 pandemic can be considered as a positive development. At the same time, studies find that e-bike riders are traveling with higher speeds, and report new types of safety incidents, that they did not experience during conventional cycling. Risk related behavior of e-bike and c-bike riders has frequently been linked to crash-risk and injury severity [6][7]. But little research has been conducted on the comparison of self-reported risk related behavior between e-bike and conventional bike (c-bike) riders. Hence, in this study, the self-reported risk-related behavior of c-bik.e and e-bike riders was investigated

Four New BL Lac Surveys: Sampling New Populations

The advent of large area deep radio and X-ray surveys is leading to the creation of many new BL Lac samples. In particular, the ROSAT All-Sky, Green Bank and FIRST surveys are proving to be rich sources of new BL Lacs. We will discuss the methods used in four independent BL Lac searches based on these surveys. Comparison of the broadband spectral energy distributions of these BL Lacs with those of previously known objects clearly points to the existence of a large previously unrecognized population of objects with characteristics intermediate between those exhibited by Low and High energy peaked BL Lacs.Comment: 4 pages, 3 postscript figures, To be published in the Proceedings of the conference "BL Lac Phenomenon" held in Turku, Finland, June 22-26, 199
