Paper deals with experimental research on the crushing of coffee beans of different kinds under quasi-static compression.The process Feeding of the crushing is described in details.It has been shown that there is variability in the crushing strength values.A relation between crushing strength and the coffee grain shape is also studied.Roasted Arabi
The aim of this paper is to determine the boiling heat transfer coefficient for the cooling liquid flow in a rectangular minichannel with asymmetric heating.The main part of the test section is made up of a vertical minichannel of 1.0 mm depth.The heating foil on the side of the fluid flowing in the minichannel is singlesided enhanced on the select
During a natural disaster, risk management for the evacuation of people in high-rise buildings is very important for saving lives.In the case of fire, all parameters such as detection, lighting, warning systems, etc.for safety must be used interactively.Determination of evacuation conditions and different ways out are important parameters during th
A mathematical immuno-tumor model EXTENSIONS proposed by A.Kavaliauskas [Nonlinear Anal.Model.Control 8, 55 (2003)] and consisting of a Cauchy problem for a system of two first-order ordinary differential equations is studied.For some particular parameters values, this model has saddle-node, Hopf and Bogdanov-Takens (BT) singularities.In the case o
Exploration of historical buildings during their life cycles is one of many aspects of the cultural heritage research.For studying different conditions of historical buildings over time, it is convenient to use photogrammetric surveys carried out in different time stages.Modern Placemats photogrammetric methods give the possibility to use archived
