Bone is a composite of the biopolymer collagen type I and the bioceramic hydroxyapatite. Two main types of regions are found in bones: cortical-the most important for its mechanical properties-and trabecular. Viscoelasticity is an essential property of cortical bone. Three viscoelastic models selected in the existing literature are analysed and com...

A unichamber silicone closed spherical pressure vessel fails after an experimentation consisting of the simulation of a typical human hearth beat. Failure occurs at diastolic expansion after 3000 cycles with a pressure of 16kPa. Following the analysis of this forensics case study, it is found that the main mechanism of failure is fatigue. This fati...

One of the most common interventions performed today is intravascular stenting. A stent is a small tubular device placed into a blood vessel to hold it open. This review covers various aspects of stents from how it is placed into the vessel (e.g. the coronary artery) to the biocompatible materials used (e.g. metal). Mechanical considerations are al...

In this book, Donald Norman raises very interesting issues relating to the process of designing an object or more generally a product. It intertwines very well real-life related examples, latest scientific research findings and exploration of surprising objects with his vision of cognitive science. Its very approaching written style and pleasant re...

ETH Zurich Researchers have developed the first Soft Artificial Heart made of Silicone in 2017. This Prototype of Artificial Heart is being analysed in terms of maximum stresses and strain that the silicone membrane can withstand with two simplification models.

The Manufacturing plan of Glan Net Device - a smart device preventing ocean pollution from its main origin: Storm Pipes - includes three main aspects which are detailed in this document: a hardware aspect which includes the physical electrical components ; a software aspect which involves all the functions that the Device provides the user with tha...

The ambition of this document is create a smart device capable of reducing pollutants from entering the ocean. The criteria of evaluation will be concerned with technical and economical variables. Prior to this report, a standards IP, benchmarking and user need-finding report was conducted and led to the development concept ideas and gather user op...

Our project is to provide the service robot named ”Stevie” an autonomous charging feature to facilitate the user’s use of the robot, removing the constraint of connecting it regularly to a socket. This includes the development and design of a power transmitter i.e. a Base station plugged to a wall and located on the ground, and a power receiver in...

Overall, the management of Merck & Co. today tries best to catch up with the management and research errors of the past, and not to reproduce them. In a time of globalization and ”low-cost”, and regarding the many poverty gaps in the world, the pharmaceutical industry faces big and sometimes contradictory challenges: to make profit to finance the r...

The main product specification standards concerning Wireless charging are Qi and AirFuel, from two competitors : the World Power Consortium and AirFuel group, which are industry standard groups. Qi standard have recently become internationally recognized thanks to the acceptation and promotion of IEC an international standards organization for all...

////////// IRRITATION EFFECT TO HUMANS FOLLOWING CAPSAICIN INTAKE ////////// 10 food components were tested on 12 individuals (aged 15 to 18 years old, including 7 females and 5 males) for three different levels of concentration of capsaicin (from three different chilli peppers : green : 250-2,500 Scoville, yellow : 5,000-10,000 Scoville and haba...

Capsaicin is the active component of chilli peppers causing the sensation of burning in humans and other mammals when it comes into contact with tissue, more commonly the oral mucosa. 10 food components were tested on 12 individuals (aged 15 to 18 years old, including 7 females and 5 males) for three different levels of concentration of capsaicin (...
