Opis:
Argumentation skills play a vital role in students’ ability to master the learning process because, by employing these skills, they can explain real-world phenomena scientifically. This research focused on developing an argumentation tool based on the engineering design process (EDP) to improve students’ argumentation skills in science classrooms. This study utilised the research methods outlined by Plomp & Nieveen, which include problem identification, design, and implementation stages. This study, which involved 150 junior high school student participants, was conducted to implement the argumentation tool as a learning material to help students to understand heat transfer information in science learning. The indicators of argumentation skills included claims, evidence, and reasoning. The study results showed that five experts validated the argumentation tool in science learning development as appropriate for implementation as a practical tool in the science learning classroom. Furthermore, students’ argumentation skills improved significantly, mainly related to developing claims and collecting evidence based on the N-gain evaluation.

Opis:
A paradox of our time is identified: on the one hand – the development of one global system (ecological, technological and social), on the other hand – the still increasing “balkanization” of science. The dynamics of this systems is a source of well-known numerous global problems. Its possibly effective solution needs adequate knowledge about the system. For this reason, counteraction to “balkanization” of science is of great practical importance. And this counteraction should comprise not only development of “transboundary” sciences (such as biochemistry or social psychology) but also establishing and developing links between very distant disciplines. This text is intended as a contribution to linking social and engineering sciences. The notion of design plays the central role in this text. Its meaning in the engineering sciences. The notion of utopia has been chosen as a partial counterpart to the term of engineering design. This notion was defined using a concept of possible world – taken from modal logic. It encompasses two ideas: this of design and that of prediction, It is claimed that we need many utopias and that their plurality is of fundamental importance for protecting us against the threats of utopianism. The paper suggests that social utopias can play a heuristic role in engineering design (particularly in the initial phase of defining technological problems), and – on the other hand – that the theory of engineering design can be supportive for, badly needed, development of methodology of utopias creation.

Opis:
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.

Opis:
This study looks into aspects of the new EU design legislation that relate to the subject-matter of digital designs and the extent to which Polish law should adapt for full harmonization. The first part examines the new open-ended definitions of a ‘design’ and ‘product’ with a focus on dematerialized items that exist solely through appearance. The second part touches upon several legal parameters serving the identification of the object of design protection. It discusses the visibility requirement embedded by the filing requirements, the eye-perception of design features, and the disconnection of the scope of protection from the designated product category. The last part takes an interdisciplinary approach based on the rules of psychology and design engineering in order to explain the issues that underline human vision, with a focus on the appearance of user interfaces. The understanding of sensory and cognitive determinants of human perception is a useful guide for a judge or examiner in the assessment of the overall impression of two designs. Because of the challenges resulting from the specificity of digital designs, this article argues that Polish law should comprehensively implement the new EU design provisions in order to prevent further difficulties in enforcement.

Opis:
This article is aimed at the engineering design of a manipulator, which is pneumatically controlled. It will serve for mounting the compressor of an air suspension system to the chassis of a sport utility vehicle (SUV) produced in the Slovak Republic. The manipulator will be used on an assembly line, on which SUVs are assembled. The designed device belongs to a group of dedicated devices, which are not produced within a serial production, however, it is the only functional prototype. Together with the manipulator structure, a pneumatic part of the assembly line including individual components, schemes and the pneumatic system will be proposed. Within the project process, all necessary customer demands, technical and safety standards have to be met. Moreover, ergonomic requirements for handling the device and other acts on the workplace have to be considered.

Opis:
Artykuł, w świetle standardu ISO/IEC 15408 Common Criteria, przedstawia przegląd zagadnień związanych z konstruowaniem i oceną zabezpieczeń wbudowywanych w dowolne produkty lub systemy informatyczne. Ocena ta dotyczy uzasadnionego zaufania do zabezpieczeń, utożsamianego potocznie z ich wiarygodnością. Po krótkim wprowadzeniu w tematykę związaną ze standardem, skrótowo opisano kilkuetapowy i dość sformalizowany proces konstruowania zabezpieczeń. W jego wyniku powstaje dokument zwany zadaniem zabezpieczeń, który specyfikuje zbiór funkcji zabezpieczających wbudowywanych w produkt lub system informatyczny. Ponadto precyzowany jest poziom uzasadnionego zaufania, utożsamiany z rygoryzmem, z jakim implementowane są te funkcje. Ciężar opracowania materiału dowodowego potwierdzającego zadeklarowany poziom uzasadnionego zaufania spoczywa głównie na konstruktorach i osobach odpowiedzialnych za procesy wytwarzania i utrzymania. Materiał wraz z produktem lub systemem informatycznym poddawany jest niezależnej ocenie według metodyki związanej ze standardem. Pozytywny i dodatkowo zweryfikowany wynik tej oceny pozwala na uzyskanie certyfikatu na spełnienie wymagań deklarowanego poziomu uzasadnionego zaufania. Produkty certyfikowane, dzięki tej niezależnej i wnikliwej ocenie, są uznawane za bardziej wiarygodne, więc mogą być używane do odpowiedzialnych zastosowań.
The paper presents a review of the issues relating to design engineering and assessment of the protections to be built into any products or informatics systems, regarding the standard: ISO/IEC 15408 Common Criteria. The assessment has been applied to the reasonable confidence in the protections, which is usually identified with the reliability of the protections. After a short introduction has been made to the subject matter related to the standard, there has been described in brief a few-stage and quite formalized process of design of the protections resulted in a document called a task of protections, which specifies a set of protective functions to be built into a product or an informatics system. Furthermore there has become specified a level of a reasonable confidence, which has been identified with a rigorism with which the functions have been implemented. The elaboration of an evidentiary material to confirm the declared level of the reasonable confidence is to be made exclusively by designers and the persons responsible for manufacturing and maintenance processes. That material including a product or an informatics system is to be evaluated by the methodology process related to the standard. The positive and additionally verified result of that evaluation allows a certificate of meeting the requirements of the declared level of the reasonable confidence to be issued. Thanks that independent and penetrating evaluation, the certified products are recognized as more reliable and may be used for responsible applications.

Opis:
W artykule przeprowadzono ocenę oprogramowania wykorzystywanego do nauki projektowania złożonych i wielkogabarytowych konstrukcji cienkościennych. Większość oferowanych środowisk graficznych umożliwia zamodelowanie struktury przestrzennej obiektu i przeprowadzenie badań symulacyjnych obejmujących np.: analizę wytrzymałościową i statyczną, obliczenia drgań własnych i wymuszonych. Moduł obliczeniowy w tego typu programach bazuje na metodzie elementów skończonych. W pracy zamieszczono przykładową ścieżkę projektową i analizę pokładu okrętu typu RO-RO, na którym zaparkował samochód ciężarowy. W przedstawionym przykładzie wykorzystano oprogramowanie firmy MSC z preprocesorem Patran i modułem obliczeniowym Nastran.
In the paper the software to the teaching of designing of complex and large-scale thin-walled structures was evaluated by the authors. The bundle of MSC software, named Patran-Nastran, was presented. The software is based on Finite Element Method. The authors, during the teaching process, focus on basic analyses: linear static strength analysis, normal mode (eigenvectors) analysis and frequency response analysis (forced vibrations calculations). An example of RO-RO ship's deck analysis was presented. The deck was loaded with the wheels of truck. A short description of the modeling process as well as the results of the analyses are presented in the paper. Discussion about objectives of the teaching process was carried out. In the authors' opinion, knowledge of that very specialized software is important not only for a calculating engineer. All mechanical engineers should have basic knowledge about the calculations process because they will be recipients of the calculations performed during structure designing. Thin-walled structures are very useful for teaching because during the structure modeling we have to choose types of FEM elements. Stiffeners may be modeled by 1-D elements (with offset) and the plates should be modeled by 2D elements. Differences between beam and rod 1D elements as well as shell, plate and membrane 2D elements should be stressed during the teaching process.

Opis:
There are many design problems need to be optimized in various fields of engineering, and most of them belong to the NP-hard problem. The meta-heuristic algorithm is one kind of optimization method and provides an effective way to solve the NP-hard problem. Salp swarm algorithm (SSA) is a nature-inspired algorithm that mimics and mathematically models the behavior of slap swarm in nature. However, similar to most of the meta-heuristic algorithms, the traditional SSA has some shortcomings, such as entrapment in local optima. In this paper, the three main strategies are adopted to strengthen the basic SSA, including chaos theory, sine-cosine mechanism and the principle of quantum computation. Therefore, the SSA variant is proposed in this research, namely SCQ-SSA. The representative benchmark functions are employed to test the performances of the algorithms. The SCQ-SSA are compared with the seven algorithms in high-dimensional functions (1000 dimensions), seven SSA variants and six advanced variants on benchmark functions, the experiment reveals that the SCQ-SSA enhances resulting precision and alleviates local optimal problems. Besides, the SCQ-SSA is applied to resolve three classical engineering problems: tubular column design problem, tension/compression spring design problem and pressure vessel design problem. The design results indicate that these engineering problems are optimized with high accuracy and superiority by the improved SSA.
