Mangrove Conservation and Biodiversity Protection Strategies in Universitas Diponegoro to Achieve Net Zero Emission

Indonesia is set the net zero emission target to be achieved by 2060. As part of that, Universitas Diponegoro (UNDIP) is committed to support the achievement of the goal by implementing several strategies. First is to reduce the amount of emission generated by the university daily activities, and second is boosting the activities of mangrove conservation and biodiversity protection. As UNDIP located in the northern part of Central Java, part of 108.000 kilometers coastline region of Indonesia, UNDIP prioritizes its academic activity and research focus on coastal region environmental and ecological development which enthuse the implementation of mangrove conservation and biodiversity protection. The strategy includes the structured mangrove and biodiversity conservation action directed by the University leaders, encouraging research and community service activities focusing on coastal region development and developing environmental-related curriculum for the students. In addition, UNDIP also supports research centers and students’ communities who focus on mangrove conservation, biodiversity protection, and coastal region development. By that, there are more than 50 types of flora in UNDIP land forest with carbon stock calculation up to 6,480.20 metric tons CO2 eq. Acc

Cell teardown and characterization of an automotive prismatic LFP battery

A key challenge in lithium-ion battery research is the need for more transparency regarding the cell design and production processes of battery as well as vehicle manufacturers. This study comprehensively benchmarks a prismatic hardcase LFP cell that was dismounted from a state-of-the-art Tesla Model 3 (Standard Range). The process steps and manufacturing peculiarities were traced by disassembling the cell and analyzing the characteristics on the material level. A butterfly-design with two jelly rolls was found for the cell design in order to minimize the void volume (6.4%). Cross-sections and microscopy analyses from the cell cap revealed the application of multiple laser-welding processes that are needed to provide a high stability and tightness. The coatings of the approximately 22m long electrodes showed a high homogeneity with thickness fluctuations less than 2µm. Scanning electron microscopy images revealed a pure graphite anode and a bimodal particle distribution within the lithium iron phosphate cathode, whereby the edges of the cathode were covered in a 27µm thick aluminum oxide (Al2O3) insulation layer. Electrochemical analyses were performed showing the improved performance of the inherent electrolyte over a common LP572 electrolyte. A gravimetric energy density of 163Wh/kg and a volumetric energy density of 366Wh/l was determined based on a nominal cell capacity of 161.5Ah. Overall, the purpose of this work is to demonstrate which design decisions and manufacturing challenges are addressed in industrial cell production, so that the focus of academic research can align with the state-of-the-art.

Проблема феномена визуальности в современном англо-американском научном дискурсе

В статье исследовано отражение феномена визуальности в современном англо-американском академическом пространстве. Особое внимание уделено освещению явления визуального поворота в исследованиях, а именно, почему внимание ученых ХХ в. привлекла визуальная культура, и как визуальность завоевывала различные социокультурные пространства. Проанализированы взаимосвязи между визуальным поворотом и привилегией зрения над другими органами чувств (окулоцентризм) и появлением новых технологий. Проникновение визуального в теорию культуры и распространение образов в самой культуре называют «визуальным поворотом» (иногда его также называют «пикториальным поворотом» или «иконическим поворотом») («pictural turn», «iconic turn»). Он был представлен в исследованиях одного из самых выдающихся теоретиков медиа и визуальной культуры У. Дж. Т. Митчелла. Со временем понятие «визуальность» успешно утвердилось не только в самой культуре, но и в других направлениях, таких как культурология, философия, социология и история, которые всебольше переплетаются через изображение. Неудивительно, что в текстах известных исследователей и теоретиков культуры, таких как Стюарт Холл, Гордон Файф, Джон Ло, Джон Питер Бёрджер, Мартин Джей, Элла Шохат, Роберт Стэм, Донна Харауэй и многих других, уделяется большое внимание изучению различных аспектов проблемы визуальности, а фокус академических исследований часто смещается на междисциплинарный уровень. В исследованиях большое внимание уделено определению визуальности и других явлений феномена видимости, онтологии зрения и видения, выявлению границ между видимым и невидимым, освещена проблема образа, теоретических свойств образа в фотографии, кинематографе, искусстве, образовании и т.д. Проблема визуального была возведена в центр новых исследований, заложен фундамент для появления новых направлений исследований, в частности визуальных. Это знаменует начало нового этапа в развитии гуманитарных исследований, когда отпростого наблюдения за тем, что мы живем в эпоху доминирования образов, мы переходим к теоретической концептуализации этого явления.

The rise and stagnation of Google Earth VR: dashing the hopes of immersive geography classrooms?

ABSTRACT Given the sensational development of virtual reality (VR) technologies in recent years, how can hopes of fully-immersive experiential learning in geography classrooms be achieved? One solution may be through Google Earth VR, which is a truly immersive app for ‘visiting’ places across the globe via a wired VR headset. The app has been an increasing focus of academic research and classroom VR sets, but many challenges exist, such as technical issues and developer neglect by Google. As the educational benefits of VR for student learning continue to be seen, can a somewhat stagnant Google Earth VR app become a mainstay in academic geography, thus realising the dream of immersive classrooms?

Combining intangible cultural heritage with clothing design can not only protect intangible cultural heritage productively, but also generate income. The article takes Shuijia Mawei embroidery as an example, takes the feasibility of combining Shuijia Mawei embroidery with clothing design as a breakthrough, and focuses on analysing the specific use of intangible cultural heritage in clothing design, so as to provide new ideas for the inheritance and protection of intangible cultural heritage, and at the same time, to provide practical experience for the development and design of the derivatives of intangible cultural heritage.

(Invited) novel Functional π-Conjugated Materials for Photonics, Electronics, and Sensing

Next generation active electronic materials used in devices are undergoing continual improvements to generate devices that are high performance, lighter, flexible, stretchable, and more energy efficient with lower cost. Carbon based novel solution processable π-functional conjugated materials are the focus of intense academic and industrial research since they are important class of soft materials for large area electronics including transistors, displays, sensors and light harvesting devices. The active organic semiconducting materials are emerging due to their tunable light absorption/emission, interesting charge transport properties, relatively adequate HOMO-LUMO energies and ink formulation capability.In my talk, I will explain the various classes of conjugated carbon-based materials either as polymers, small molecules or quantum dots prepared via chemically and electrochemically using various novel aromatic conjugated building blocks. In this presentation, the design, synthesis, optoelectronic properties, and device performance of novel advanced materials for field effect/electrochemical transistors, perovskite solar cells, light emitting diodes, optical sensors and various sensing devices will be discussed. Such materials and devices have great potential in future electronics, energy, health, and environmental monitoring. Figure 1

Environmentally Responsible Lightweight Passenger Vehicle Design and Manufacturing

AbstractThe mass reduction of passenger vehicles has been a great focus of academic research and federal policy initiatives of the United States with coordinated funding efforts and even a focus of a Manufacturing USA Institute. The potential benefit of these programs can be described as modest from a societal point of view, for example reducing vehicle mass by up to 25% with modest cost implications (under $5 per pound saved) and the ability to implement with existing manufacturing methods. Much more aggressive reductions in greenhouse gas production are necessary and possible, while delivering the same service. This is demonstrated with a higher-level design thinking exercise on an environmentally responsible lightweight vehicle, leading to the following criteria: lightweight, low aerodynamic drag, long-lived (over 30 years and 2 million miles), adaptable, electric, and used in a shared manner on average over 8 h per day. With these specifications, passenger-mile demand may be met with around 1/10 of the current fleet. Such vehicles would likely have significantly different designs and construction than incumbent automobiles. It is likely future automotive production will be more analogous to current aircraft production with higher costs per pound and lower volumes, but with dramatically reduced financial and environmental cost per passenger mile, with less material per vehicle, and far less material required in the national or worldwide fleets. Subsidiary benefits of this vision include far fewer parking lots, greater accessibility to personal transportation, and improved pedestrian safety, while maintaining a vibrant and engaging economy. The systemic changes to the business models and research and development directions (including lightweight design and manufacturing) are discussed, which could bring forth far more sustainable personal transportation.

Development of Air Defence in the United States between 1917 and 1945

The article presents the results of academic research focusing on the origins and development of anti-aircraft artillery in the United States which was to guarantee the safety of American soldiers fighting in the First and Second World Wars. The findings of this study confirm that, in the early days, knowledge of the phenomena occurring in the air dimension of armed struggle was primarily empirical. As early as 1916, Alexander Graham Bell warned of the possibility of air raids on the United States. Over the next 25 years, experts conducted research into air defence, which became crucial in its subsequent development. The basis for the development of air defence was the emergence of a new weapon at the end of the First World War, i.e., anti-aircraft artillery. Basing on the experience of the United States from the First World War in the interwar period, air defence began to be seen in terms of a system whose main task was to detect and destroy enemy aviation, attacking troops, civilians and facilities at the rear of the front.
 Considering the outlined problem scenario and the subject of the research, it was assumed that the aim of the article will be to discuss the stages of the development of air defence in the United States in the years 1917–1945 and the experience of US anti-aircraft artillery gained on the fronts of the First and Second World Wars.

Current Status of Technological Innovation Cluster Research

The research on innovation clusters has become the focus of academic research and scientific and technological decision-making of governments around the world. The construction of innovation clusters is of great significance to cultivate strategic emerging industries, enhance regional innovation capacity and promote the transformation of economic development mode. However, at present, the theoretical research on technological innovation clusters is not deep enough, and the theoretical framework is still not clear. On the basis of literature research, this paper starts with the concept of innovation cluster, associates it with technology cluster, and jointly introduces the origin and concept of technology innovation cluster. Based on the analysis of various literature, the shortcomings of the current research on technology innovation cluster and the direction of the next research are pointed out.

A research agenda for the sustainability of the tourism industry: A childism perspective on overtourism

Academic research focusing on overtourism, and related negative impacts have overlooked the role children could have played in the sustainability of the tourism industry. This lack of interest is surprising knowing that: first, they are the future of the industry; second, when empowered they can be agents of change. Subsequently, the objective of the study is to show that research on overtourism is totally compatible with childism. Using a bibliometric and lexicometric analysis, the study suggests how the literature on overtourism has evolved over time and demonstrates the absence of children in this evolution. As a result, this study proposes a strategy for children to be involved in initiatives to mitigate the negative impacts of overtourism. Equally important, this study is providing a research method to develop a research agenda, alongside three key main area for research.

Searching Information through Technology and Human Interaction

The Computer Age, also known as Digital Age, and Information Age, and New Media Age, has been the most impactable historical period of human civilization. If well the truth that its precursor, the Industrial Revolution, drastically changed the way societies lived and worked and plaid, the magnitude of its impact in terms of communication cannot be compared with the one the Computer Age has brought into today’s society. Consequently, technology and human interaction have become a modern society norm. Indeed, a well-considered focus for academic and scientific research. The study takes on the Communication philosophy and Communication Theory to present an outlook on searching for information through technology and human interaction. It focuses on the Shamon Weaver Model to transcribe this model communication concept into a Search Engine Communication Model (SECM). The study has used a qualitative method approach for the collection and analysis of correlated materials such as books and publications and Internet-accredited websites.

Continuous transfer of neural network representational similarity for incremental learning

The incremental learning paradigm in machine learning has consistently been a focus of academic research. It is similar to the way in which biological systems learn, and reduces energy consumption by avoiding excessive retraining. Existing studies utilize the powerful feature extraction capabilities of pre-trained models to address incremental learning, but there remains a problem of insufficient utilization of neural network feature knowledge. To address this issue, this paper proposes a novel method called Pre-trained Model Knowledge Distillation (PMKD) which combines knowledge distillation of neural network representations and replay. This paper designs a loss function based on centered kernel alignment to transfer neural network representations knowledge from the pre-trained model to the incremental model layer-by-layer. Additionally, the use of memory buffer for Dark Experience Replay helps the model retain past knowledge better. Experiments show that PMKD achieved superior performance on various datasets and different buffer sizes. Compared to other methods, our class incremental learning accuracy reached the best performance. The open-source code is published athttps://github.com/TianSongS/PMKD-IL.

Study on Anti-Icing Performance of Biogas-Residue Nano-Carbon Coating for Wind-Turbine Blade

Icing is a common phenomenon in nature and has a serious impact on wind turbines. Anti-icing coatings have become a major focus of industrial applications and academic research. In this study, a hydrophobic nano-carbon coating was prepared from corn-straw-biogas residue. The characterization results of the SEM, BET, FTIR, and XRD analyses showed that the hydrophobic nano-carbon has good pore structure and crystal structure. The hydrophobic and anti-icing effects of the carbon were confirmed by contact-angle measurements and anti-icing experiments. The ice thicknesses of the hydrophobic nano-carbon-coated aluminum-alloy blade (AAB) and bakelite blade (BB) were found to decrease by 1.20 mm and 1.10 mm, respectively, compared with those without coating; their weights decreased by 2.00 g and 1.31 g, respectively. The ratios of the icing areas before and after the hydrophobic nano-carbon coating of the AAB and BB were 8.15% and 9.65%, respectively. In brief, this method is a more effective technique for creating anti-icing coatings on wind-turbine blades and other outdoor apparatus.

Secure and Efficient Federated Gradient Boosting Decision Trees

In recent years, federated GBDTs have gradually replaced traditional GBDTs, and become the focus of academic research. They are used to solve the task of structured data mining. Aiming at the problems of information leakage, insufficient model accuracy and high communication cost in the existing schemes of horizontal federated GBDTs, this paper proposes an algorithm of gradient boosting decision trees based on horizontal federated learning, that is, secure and efficient FL for GBDTs (SeFB). The algorithm uses locality sensitive hashing (LSH) to build a tree by collecting similar information of instances without exposing the original data of participants. In the stage of updating the tree, the algorithm aggregates the local gradients of all data participants and calculates the global leaf weights, so as to improve the accuracy of the model and reduce the communication cost. Finally, the experimental analysis shows that the algorithm can protect the privacy of the original data, and the communication cost is low. At the same time, the performance of the unbalanced binary data set is evaluated. The results show that SeFB algorithm compared with the existing schemes of horizontal federated GBDTs, the accuracy is improved by 2.53% on average.

A patent-based analysis of the evolution of basic, mission-oriented, and applied research in European universities.

The dynamics of basic and applied research at university and industry have steadily changed since the Eighties, with the private sector reducing its investments in science and universities experiencing significant remodelling in the governance of their funding. While studies have focussed on documenting these changes in industry, less attention has been paid to observe the trajectories of basic and applied research in universities. This work contributes to fill this gap by looking at the evolution of publicly funded research that has been patented by universities between 1978 and 2015. First, we adopt a critical perspective of the basic versus applied dichotomy and identify patents according to three typologies of research: basic, mission-oriented, and applied research. Second, we describe the evolution of these three typologies in universities compared to industry. Our results show that over the years,patents from academic research that was publicly funded have become more oriented towards purebasic research, with mission-oriented basic researchand pureapplied research decreasing from thelate 1990s. These results complement and extend the literature on basic and applied research dynamics in the private sector. By introducing mission-oriented research as a type of basic research with consideration of use, the work problematises the basic and applied research dichotomy and provides insights into the evolution of academic research focus, offering a more complex picture of how university research contributes to industry and broader social value creation.

Mechanical Analysis and Optimal Design of Wave Energy Device

At present, the global energy problem is serious. Wave energy is the kinetic energy and potential energy of waves on the ocean surface. Because of its high energy density, wide distribution, and long continuous operation of the device, it has become the focus of academic research. The key problem to be solved urgently for the large-scale application of wave energy is how to optimize the energy conversion efficiency of wave energy devices. This paper starts from the Newtonian dynamic equation, analyzes the motion state of the wave energy device in different wave environments, and studies the optimization and control of its power output. This paper first adopts the analysis method of first whole and then isolation, and establishes a one-dimensional coordinate system with the zero point of sea level. Then, the force analysis of the system is carried out, the dynamic differential equation is established, and the initial draft of the system is solved through the initial balance equation. Since the dynamic equation is a second-order linear ordinary differential inhomogeneous linear equation, the fourth-order Runge is used. The Kutta method is used to solve the problem, and the numerical solution for the position and velocity of the float is obtained. Secondly, the movable coordinate system is established with the float as the reference system, and the force analysis of the oscillator is carried out to obtain its relative dynamic equation. Then, the initial relative position of the oscillator is solved through the initial balance equation, and the relative dynamic differential equation is obtained by using the fourth-order Runge-Kutta method to obtain the numerical solution of the relative position and relative velocity of the oscillator with respect to time. Finally, the numerical solution of the absolute position and absolute velocity of the oscillator with respect to time is obtained through coordinate transformation.

Mess or match? How do academic perspectives meet the practitioner perspectives in terms of digital transformation?

We present research comparing theoretical and practical knowledge on digital transformation. By determining the gap and synchronization of academic research and practitioners' focus in the digital age, the paper aims to solve the puzzle of “transformative strategy,” “knowledge management,” and “innovation” that underlines the organisational design. Contributing to the method, text mining and TFIDF tests are run to find the most centric view on digital transformation, thus visualising the future path for digital transformation. Text mining is suitable for detecting the common and differences between the two perspectives. As a result, the research suggests that the field of interest for cross-professional collaboration is data and technology, organisational oriented, whereas the practitioners focus on health, services and insurers, and banking.

Inuit-defined determinants of food security in academic research focusing on Inuit Nunangat and Alaska: A scoping review protocol.

Academic research on food security in Inuit Nunangat and Alaska frequently adopts the Food and Agriculture Organization of the United Nations' working definition of food security and Western conceptualisations of what it means to be 'food secure'. However, in 2014, the Alaskan branch of the Inuit Circumpolar Council (ICC) stated that academic and intergovernmental definitions and understandings 'are important, but not what we are talking about when we say food security'. The organisation subsequently developed its own conceptualisation and definition: the Alaskan Inuit Food Security Conceptual Framework (AIFSCF), which in 2020 received informal assent by ICC-Canada. This protocol establishes a review strategy to examine how well academic research reflects Inuit conceptualisations and understandings of food security, as outlined in the AIFSCF. Review structure and reporting will be completed according to adapted RepOrting standards for Systematic Evidence Syntheses (ROSES) guidelines. A comprehensive search strategy will be used to locate peer-reviewed research from Medline, Scopus, Web of Science and the Arctic and Antarctic Regions (EBSCO) databases. Dual reviewer screening will take place at the abstract, title, and full-text stages. Different study methodologies (qualitative, quantitative, and mixed methods) will be included for review, on the proviso that articles identify drivers of food security. An a priori coding framework will be applied by a single reviewer to extract data on publication characteristics, methods and article aims. Deductive thematic content analysis will then identify the frequency and precedence afforded within literature to the drivers and dimensions of food security identified by the AIFSCF.

Review and Prospect of Research on Enterprise Resource Based Theory and Enterprise Core Competence Theory

The concept of enterprise capability and the origin of the theory of enterprise capability both began before and after the first industrial revolution and gradually improved with the continuous development of economy and enterprises. The theory of enterprise capability covers a wide range of contents, among which the theory of enterprise resource base and the theory of enterprise core capability have always been the focus of academic research. Based on the brief introduction of the connotation of enterprise capability theory and the four major capability theories, the text will conduct in-depth research on enterprise resource-based theory and enterprise core capability theory. This paper mainly expounds the enterprise resource-based theory from two aspects: theoretical review and theoretical evolution.
