The preservation of historical documents is a task that requires a multidisciplinary team. Mechanical engineering can make valuable contributions. Historical documents made of paper have unique characteristics that must be considered for their preservation and exhibition. Specially designed encasements have emerged as a solution to meet these requirements. In the present research, a comparative design study was carried out. The study comprises identifying the main functions of the encasements. Subsequently, it is analyzed how the capsules that appear in the literature have solved these functions. With the information obtained, three new encasements were designed for historical documents in Mexico. From the results and design experiences, some insights and design principles were obtained; these can be universally applied.

Podczas odbywających się w dniach 14-16 marca Międzynarodowych Targów Aparatury i Wyposażenia Medycznego SALMED 2012 w Poznaniu zaprezentowano ofertę edukacyjną Międzywydziałowej Szkoły Inżynierii Biomedycznej AGH w zakresie kształcenia kadr. Oferta ta, zgodnie z nazwą szkoły dotyczy technicznego wsparcia medycyny i kierunku studiów "inżynieria biomedyczna'. Zasadniczym celem wystąpienia w roli wystawcy było dotarcie do licznie reprezentowanych tam przedstawicieli producentów wyrobów medycznych oraz lekarzy i menedżerów służby zdrowia z informacją o wiedzy, umiejętnościach i kompetencjach naszych absolwentów. Podobnie, jak w przypadku produktów oferowanych na targach, nasi absolwenci prezentowali swoje atuty praktycznie poprzez wykonane projekty inżynierskie. Chociaż prezentowane były dwa przykładowe projekty, wrażenie profesjonalnego podejścia i wysokiego poziomu merytorycznego dotyczyło także pozostałych projektów zrealizowanych w MSIB. W oczach odwiedzających targi, prezentacja szkoły budziła skojarzenie z kształceniem wysokiej jakości, dostosowanym do bieżących potrzeb rynku pracy.

During the International Trade Fair of Medical Equipment and Instruments SALMED 2012 held in Poznań from 14th to 16th March 2012 we presented the educational offer of Multidisciplinary School of Engineering in Biomedicine (MSIB) AGH-University of Science and Technology concerning the education of professionals for technical support of medicine in the faculty of biomedical engineering. Our main goal of participation as an exhibitor was to reach to widely represented manufacturers of medical instrumentation, doctors and officers of healthcare management and recommend the knowledge, skills and competences of our graduates. Similarly to the products presented in their intended actions, our graduates were presenting their attitudes in a practical way by means of completed Engineer Diploma Projects. Although, only two examplary projects were presented, the opinion of professional approach and high merit was equally attributed to other projects completed at MSIB. In result of the presentation, the MSIB acquired in visitors’ eyes a connotation of quality education continuously adapted to the demands of job market.

Purpose: The aim of this work consists in developing a design methodology for preventive ergonomics and comfort analyses of Human-Machine-Interface (HMI). Design/methodology/approach: Our method is based on the simulation of the main posture that a digital human model (a manikin representing, for example, a car’s driver) takes while using a machine (in this work, driving a car), in order to judge human safety and comfort during interaction with dashboard, instruments’ panel, levers and other commands. The ergonomic analyses are made using an appropriately modified OCRA (Occupational Repetitive Actions Index) protocol, in order to evaluate different involvement degrees of upper limb segments in comfort action range. Findings: The three-F principle -Human fit, form and function- is becoming the most addressed guideline for improvement and appeal-increasing of product in the current demanding global marketplace. Our work uses modern technologies and new design methods, developed by our research team, and allows to manage and optimize Human Machine Interface under “comfort” point of view. Research limitations/implications: Today, designers attempt to elaborate product development methodologies that conform itself towards best comfort performance; our work helps them to override several problems that a product development plan shows. Future developments can be made using biomechanical parameters and studies in order to better quantify and evaluate the comfort parameters. Practical implications: Using our approach and methods, comfort analysis can be made in the earliest part of the design development of a product so that designers can appreciably reduce time to market and improve and innovate comfort performances. Originality/value: First paper on this matter has been presented by one of the authors in 2008 in a World Automotive Congress; it has been the first paper on this specific matter. All over the world, new research frontier, on these topics, is going towards HMI evaluation under physical comfort and cognitive ergonomics point of view. Our paper represents, today, the newest and more specific development method, especially in automotive field of research.

Purpose: A method for identifying parameters of a full-car model for active suspension design Design/methodology/approach: The method is based on ERA/OKID identification procedure developed by Juang [1]. Findings: Numerical results show a good agreement with real system parameters. Research limitations/implications: Results show that this method works well only with a high signal-to-noise ratio. Practical implications: This method can be used as an aid to active suspension design. Originality/value: This procedure has been tested on the full-car model of suspension system in two cases: a) full-state measurements; b) not full-state measurements.

Purpose: Investigation of dry friction parameters on the control system of a cart pendulum. Design/methodology/approach: A geometrical approach has been used to analyze the influence of bearing friction on the cart-pendulum dynamics. This approach was developed by one of authors in the paper “ Influence of the Variation between Static and Kinetic Friction on Stick-Slip Instability” pubblished by WEAR 1993. Findings: Relations that allow us to evaluate how the friction parameters of bearings influence the performances of the control system of a cart-pendulum. Research limitations/implications: The “a priori knowing” of friction parameters is the intrinsic limitation of this method. Originality/value: A novel methodology for designing of more effective control systems.

Purpose: of this paper: The aim of this paper is to present a simple hybrid simulation system, which is composed of virtual reality software and a mathematically oriented application. From the engineer’s point of view, an important possibility is to link together the mathematical software programs with these for creating presentation graphics or virtual reality, in order to create a simulation system with the large customisability. Design/methodology/approach: The coupling of mathematical and virtual reality system can be done in several different ways, using mechanisms for the Interprocess Communication. Findings: It has been assumed that EonX control will be used in a program conceptually similar to the EON Viewer, but equipped with support of basic interprocess communication interfaces in order to maximize flexibility and possibility of data exchange with different applications. Research limitations/implications: The one of specific requirements is to create an appropriate virtual world in EON Studio with use of external events nodes. Practical implications: The simple application named SockED has been created for testing purposes. The SockED application, which is hosting EonX control, acts as DDE server. As an external application any mathematical program that supports the DDE communication can be used (eg. Microsoft Excel, Matlab). There is also theoretical possibility of use the Programmable Logic Controller in similar manner like in case of SCADA application, but this case was not tested yet. Originality/value: There is no program on the market that allows complicated mathematical computation along with high resolution, 3D presentation graphics. The creation of SockED application allowed combining a mathematical program with the powerful graphics engine from EON Reality.
