Exploring the Potentials of Sidoarjo Volcanic Mud as Construction Materials
D. Hardjito, Civil Engineering Department, Petra Christian University, Surabaya, Indonesia

This year of 2014 is marked as the eight anniversary of Sidoarjo or LUSI volcanic mud eruption. More than 640 hectares of productive land has been submerged, and yet the eruption is still continue. This presentation reviews the search to uncover the Sidoarjo volcanic mud potential as construction materials. The mud is in semi-crystalline state in its original form, and it is rich in silicon and aluminium oxides, with the total amount of SiO2, Al2O3 and Fe2O3 is more than 85%. Calcination at gigh temperature in between 600-8000C for a certain period of time, followed with grinding to reduce the particle size to less than 63µm, convert the mud to be an amorphous and reactive material. The treated mud is an excellent pozzolanic material, suitable for making high volume pozzolanic mortar or concrete. At the same time, it is a strong candidate for precursor of geopolymer material.

Keywords: Construction material, geopolymer, pozzolanic material, Sidoarjo mud, volcanic mud

Advanced methods for the synthesis and design of articular prostheses
Vincenzo Parenti-Castelli, Department of Mechanical Engineering-DIN University of Bologna

This talks presents a novel approach to for the synthesis of mathematical models of diarthrodial human joints. The models rely upon three-dimensional equivalent mechanisms whose links have a strict correspondence with the main joint anatomical structures. The focus of the talk is on the lower leg joints, with particular attention to the knee and the ankle joints. The approach features three basic steps by which the kinematic, the kinetostatic and the dynamic models of the studied joint can be respectively synthesized.

Special attention is devoted to the kinematic and kinetostatic models. The former can reproduce the joint passive motion, that is the motion of the joint under virtually unloaded conditions, while the latter can reproduce the joint motion under any external loads.

The kinematic model proves to be of great relevance for a deeper understanding of the role played by the joint anatomical structures that constrain the bone relative motion, and is the basic step from which the kinetostatic and dynamic models can be consistently developed. The kinetostatic model allows the analysis of the joint stability, enlightening the role played by all the passive structures of the joint and by some of the main active structures (muscles) of the joint.

The kinematic and kinetostatic models prove to be efficient and powerful tools for the design of articular prostheses. Examples of knee prosthesis designs are finally reported.

Human Illbeing Sensing by Smartphones and Wearable Sensors
Esko Alasaarela, Department of Electrical Engineering University of Oulu

One of the major problems in the world is illbeing, which is not only lack of wellbeing. There are many different view angles to define illbeing and wellbeing, such as quality of life, living standard, wealth and health. In the present study six main dimensions on the illbeing–wellbeing axis are defined as: 1) Physical (painful–healthy), 2) Mental (depressed–vital), 3) Social (isolated–accepted), 4) Secure (worried–confident), 5) Dominance (forced–free) and 6) Material (poor–wealthy) ill-/wellbeing. The question is: How can one or more of the dimensions of the illbeing–wellbeing axis of people be sensed and measured?

Sensor, information and telecommunication technologies have taken enormous development steps during the last few decades. Smartphones and even cheap phones include sensors and other facilities to detect, measure and collect user data. The data can be processed to indicate several parameters of the user’s status, such as changes in activity, mood, emotions, friends’ network and even his/her environmental conditions. In addition, tiny wearable sensors, which can be wirelessly connected to phones, broaden the opportunity to detect and measure changes of their users’ physiological, mental or social status. The idea of the present paper is to open the potential of smartphones and wearable sensors in sensing and measuring illbeing of people.

The main goal of this study was to map the needs of sensing illbeing of people and to collect a review of potential solutions for this use. In addition, an objective was to create new ideas to solve the problem of illbeing by applying smart future technologies. The present paper is based on a wide study of literature and a survey among experts and potential users of the found solutions. School bullying was studied as a practical example of illbeing.

Illbeing is a severe and worsening problem in the world. An interesting feature is that most of the human wellness solutions are addressed to the wellbeing people and not to the illbeing. Mobile applications are developed and marketed for health, dietary, fitness, sport and game uses. One reason to this is that their customer groups are wealthier to buy the products and services. Anyway, the same sensor and service technologies could also be applied to illbeing sensing. The easiest solutions will be those detecting and measuring physical, mental and social illbeing. The most promising way to entrance into this market is to use the development cooperation funding instruments, such as African and Asian Development Funds, European Regional Development Fund and World Bank.

In the near future the mobile technology industry will enter to the underdeveloped world market with their cheap smart devices, phones, tablets and sensors. Nevertheless, the main target of the industry is to deliver speaking and chatting services as well as Internet and games. However, from an ethical point of view it would be most important to ensure that those devices can also serve as a help in illbeing problems of poor and suffering population.

Waste Paphia Undulata Shell as a Potential Heterogeneous Catalyst for Fatty Acid Methyl Esters Production
Suryadi Ismadji, Department of Chemical Engineering, Widya Mandala Surabaya Catholic University, Surabaya, Indonesia

The production of biodiesel from palm oil using a solid catalyst waste Phapia undulate has been studied. The catalyst was prepared by calcination of the Phapia undulate shell at 900oC for 2 hours. The catalyst was characterized by FTIR, XRD and XRF methods. Different reaction parameters were employed in order to obtain maximum yield of biodiesel. The Characterization of biodiesel includes the analysis of viscosity, density, flash point, cetane number, and the content of FAME using GC. The optimum parameter for maximum yield of biodiesel are palm oil /methanol mole ratio 1:8, catalyst content 4% wt, reaction time 5 hour, with constant temperature of 60ºC and rate of mixing 700 rpm.
