Abstract: Innovation ecosystems are widely known as dynamic, self-adapting and co-

evolving structures whose main objective is to create innovation. However, there still

remains unexplored formation methodology and boundary settings. From this point of

view, the morphological analysis aims to fill the gap in terms of identification and

exploration of all forming possibilities in order to create an extensive framework,

which will identify the main innovation ecosystems’ attributes required.

Keywords: innovation ecosystems, triad actor-relation-role, morphological analysis,

Abstract: MP3, formally MPEG-1 Audio Layer III or MPEG-2 Audio Layer III, is an

audio coding format for digital audio and has shown an exponential growth since

1995, making ".mp3" the most searched term in early 1999 and a standard today for

audio encoding. Different encryption algorithms, such as AES, Partial Encryption,

DES, RC2 or RC6 are applied to MP3 files to secure the audio data, either

before/during MP3 compression or after compression, especially to protect the files

against copyright infringement. This article evaluates the security solutions proposed

so far in the literature with the main scope of identifying new creative themes for

audio data encryption by applying the method of diagramming ideas.

Keywords: Audio; Creativity; Method of diagramming ideas; Security.

Abstract: End milling is a machining method applied to obtain flat surfaces. In the

efficient use of the end milling process, the proper selection and use of the cutting tool

are important aspects. In order to develop experimental research in terms of increasing

the productivity of the machining process and improving the surface quality, the

axiomatic design could be used. A first step in applying the axiomatic design is to

develop the functional requirements corresponding to the product to be obtained. In this

way, the functional requirements for the end milling tool were taken into account to

define its main components.

Keywords:A End Milling; Rotating tool milling; Axiomatic Design.

Abstract: Hydrogels are promising materials for tissue engineering purposes as a

result of their high resemblance with native extracellular matrix. Among all the

polymers that can be used to create hydrogels, natural polymers offer several

advantages. Cellulose, the most abundant, renewable natural polymer, is a very

promising material with properties such as mechanical robustness, biodegradability,

hydrophilicity and biocompatibility. These properties are responsible for the extensive

use of cellulose in a wide spectrum of applications that include pharmacy, agriculture,

medical science, industries and so many other related branches. Highly porous

materials with a three-dimensional hydrophilic polymer network can be prepared from

cellulose. Usually, the polymeric networks exhibit a poor mechanical behaviour,

hindering their use in several applications. Therefore, the strategy described in this

study is to create cellulose-based hydrogels with controlled structural and mechanical

properties and with applicability in the biomedical field.

Keywords: cellulose; hydrogels; porosity; biomaterials; tissue engineering.

Abstract: The current paper addresses the problem of selecting the most suitable abandoned narrow

gauge railway for rehabilitation by considering and comparing the architectural heritage values and

state of conservation of its annex buildings. Four semi-abandoned heritage railways are used as case

studies in order to determine which is the most fitting for reuse from these perspectives. By employing

the decision matrix method, we have demonstrated that the best possible outcome for architectural

heritage preservation is the railway which contains a large number of buildings which are in a

relatively good state of conservation, despite the fact that only a small percentage of these buildings

have specific primary architectural features (ornamentations, details).

Keywords: decision matrix; comparison; narrow gauge railway; heritage;

architecture; conservation.

Abstract. Cellulose is a versatile natural polymerwhich provides a good platform for

construction of different hydrogel systems with distinctive properties. Several tri-

dimensional formulations based on cellulose were designed and preliminary tested to

be used in biomedical applications, with focus on drug delivery systems. The main

objective of this paper was to study the influence of the preparation formula and

method on the morphology, density, swelling degree and sorption capacity of these tri-

dimensional networks. The resulting porous microarchitectures are strongly

influenced by the composition of hydrogel formulations and freezingtemperature.

Scanning electron microscopy (SEM) analysis revealed a uniform, highly porous

surface, with homogeneously distributed well-defined pores, which are influenced by

the cross-linking degree and also by the freezing temperature prior lyophilization, as

have been confirmed by density and swelling measurements. The dynamic vapor

sorption (DVS) isotherms showed that the preparation method directly influences the

sorption capacity of the gel formulations, data which are in good correlation with the

swelling information. The variations of the freezing process rate and of the cross-

linking agent concentration generate different structures with controlled porosity, a

key feature in drug delivery applications.

Keywords:cellulose-based hydrogels,cross-linking degree, morphological features

Abstract: The paper proposes an approach related with the precision of a 3D printer

revealed in 2D circular trajectories displacement, generated by a simultaneously

controlled displacement on two orthogonal axles (abscissa and ordinate). The

displacement on each axis is experimentally controlled using two non-contact optical

sensors (optoNCDT 2000) which convert a displacement into a electrical signal. This

signal is numerical acquired by a computer via a numerical oscilloscope PicoScope

4824. The real trajectory is generated and analyzed (related by shape, mathematical

description and precision) using computer calculus features.

Abstract: Cellulose is the most abundant biopolymer, and it has been used in different

areas because of its unique properties such as hydrophilicity, low-cost,

biodegradability, biocompatibility, and non-toxicity, which makes it a good feedstock

for the synthesis of biocompatible hydrogels. Cellulose-based hydrogels are of great

interest in biomedical applications including tissue engineering, drug delivery, wound

dressing, etc. The present work reports the preparation of novel cellulose-dextran

hydrogels, developed for heart valve tissue engineering. The hydrogels were

characterized by swelling measurements, scanning electron microscopy (SEM) and

cytotoxicity assays. Various degrees of swelling were obtained as a function of

hydrogels composition. SEM demonstrated microporous structure of the hydrogel. In

vitro studies, such as assessment of cell cytotoxicity, showed their excellent

biocompatibility.

Abstract. The paper aims to determine methods to optimize the matrix geometry in order

to thermoform the open-box parts made of composite materials based on vegetable

fibers, especially in the corners area for improving the surface quality, obtaining the

desired curves and increasing the resistance to avoid the formation of folds, excessive

thinning or rupture of the material. For this purpose were conducted numerical

simulations using Dynaform software for the thermoforming process of two different

parts, and Solid Simulation was used to track the deformation and strength of the parts,

varying the wall thickness of the side plates.
