Qingdao, as a city with a colonial history, has numerous architectures that combine traditional Chinese architectural style and Western architectural style. One of the most distinctive types of architecture is the church. Churches have significant mental support functions as well as their function as shelters. They are symbols of the city, and valuable for the city to present its architectural scene. This article wishes to state the backgrounds and history of Catholicism and Protestantism; compare the differences in external spaces, internal spaces, decorations, and volume of Qingdao catholic church and Qingdao Christian church to analyze the architectural differences based on different religious backgrounds; emphasize the characteristics and connotations for churches. Studying church architecture can reveal the creativity and technical proficiency of ancient architects and craftsmen. Church architecture encompasses knowledge and skills from various fields, including structural engineering, sculpture, painting, and decoration. Such research contributes to the advancement of architectural design and engineering technology. Church architecture is a reflection of human creativity and cultural traditions, and it holds significant importance for the study and preservation of cultural heritage.

Real-time image processing and pattern recognition applications have found a new paradigm in neuromorphic computing systems. In this paper, we quantitatively compare neuromorphic architecture performance to that of conventional computing techniques. We study processing speed, accuracy, and energy usage for diverse image processing jobs using a controlled experimental methodology. The outcomes highlight the advantages of the Neuromorphic architecture, which is distinguished by quicker processing times and greater precision. These results demonstrate the effectiveness of event-driven spiking neural networks and are consistent with earlier studies. Comparisons with hybrid architectures highlight the Neuromorphic architecture's strength as a stand-alone system and point to simpler implementations. However, issues with accuracy fluctuation and the requirement for scalability continue, emphasizing areas for more study. The energy economy of neuromorphic architectures makes them essential parts of real-time image processing and pattern recognition as the field develops.

Deep learning is a branch of machine learning with many highly successful applications. One application of deep learning is image classification using the Convolutional Neural Network (CNN) algorithm. Large image data is required to classify images with CNN to obtain satisfactory training results. However, this can be overcome with transfer learning architectural models, even with small image data. With transfer learning, the success rate of a model is likely to be higher. Since there are many transfer learning architecture models, it is necessary to compare each model's performance results to find the best-performing architecture. In this study, we conducted three experiments on different datasets to train models with various transfer learning architectures. We then performed a comprehensive comparative analysis for each experiment. The result is that the DenseNet-121 architecture is the best transfer learning architecture model for various datasets.

Power consumption is very critical for portable video applications. During compression, the motion estimation unit consumes the largest portion of power since it performs a huge amount of computation. Different low power architectures for implementing the full-search block-matching (FSBM) motion estimation are discussed. Also, architectural enhancements to further reduce the power consumed during FSBM motion estimation without sacrificing throughput or optimality are presented. The proposed approach achieves these power savings by disabling portions of the architecture that perform unnecessary computations. A comparison between the different architectures including our enhancements and others is presented using simulation and analytical analysis. Different benchmarks are used to test and compare the discussed architectures. Analytical and simulation results show the effectiveness of the enhancements.

In this paper, we present and compare efficient low-power hardware architectures for accelerating the Packet Data Convergence Protocol (PDCP) in LTE and LTE-Advanced mobile terminals. Specifically, our work proposes the design of two cores: a crypto engine for the Evolved Packet System Encryption Algorithm (128-EEA2) that is based on the AES cipher and a coprocessor for the Least Significant Bit (LSB) encoding mechanism of the Robust Header Compression (ROHC) algorithm. With respect to the former, first we propose a reference architecture, which reflects a basic implementation of the algorithm, then we identify area and power bottle-necks in the design and finally we introduce and compare several architectures targeting the most power-consuming operations. With respect to the LSB coprocessor, we propose a novel implementation based on a one-hot encoding, thereby reducing hardware’s logic switching rate. Architectural hardware analysis is performed using Faraday’s 90 nm standard-cell library. The obtained results, when compared against the reference architecture, show that these novel architectures achieve significant improvements, namely, 25% in area and 35% in power consumption for the 128-EEA2 crypto-core, and even more important reductions are seen for the LSB coprocessor, that is, 36% in area and 50% in power consumption.

Ces dernières années, une intuition remarquable a eu un retentissement important : le droit serait capable d’accueillir des visions du monde, des cosmologies autres que naturalistes, c’est-à-dire autres que celles qui voient le monde fait de discontinuités entre humains et non humains, entre humains et entités de la nature. La plasticité de la personnalité juridique, les fictions et opérations que le droit promeut permettraient non seulement d’accueillir des entités non humaines en tant que sujets de droit, mais aussi de proposer de nouvelles régulations face à la crise écologique. Cet «animisme juridique » revêt pourtant diverses formes qu’il faut savoir mettre en tension pour bien comprendre la portée des reconfigurations ontologiques en jeu. Cet article opère cette mise en tension en comparant, grâce à une analyse anthropologique, les cas de l’Équateur et de la Bolivie afin de montrer qu’il y a au moins deux manières de penser ces types d’excursions juridiques. La première – celle de l’Équateur – montre un animisme juridique fonctionnant comme une jonction entre des conceptions traditionnelles/ autochtones de la nature et des opérations techniques/ modernes du droit, débouchant alors sur un droit de la nature technique, opérationnel et atomisé. La deuxième – celle de la Bolivie – bien qu’elle soit moins techniquement opérationnelle, instaure un hyper-sujet, la Pachamama, qui fonctionne comme architecture de diplomatie cosmologique, instaurant un tiers garant sacré et dessinant de nouveaux territoires d’inaliénabilité.

The Former German Governor’s Residence in Qingdao was by far the most spectacular building in residential architectures on the German Colonial period. This article studied architectural art of the Former German Governor’s Residence from architectural plan layout, building facades decorating, building structures and materials, and made these three respects compare with the Chinese traditional residential architecture. The architectural plan layout was in common about separate house on the German Colonial period, it inherited the German romantic style of the traditional residential buildings since the 16th century; its facades kept different and changeful; but primary and secondary clear, gorgeous, lively and dignified. The architectural structure was brick stone and wood hybrid construction. In this eclectic style of the building could be seen Germany was one of the birthplaces of the Modern Movement, and it had begun to explore using modern materials and new technologies, but its architectural forms was still the old form.

Transformer architectures are highly expressive because they use self-attention mechanisms to encode long-range dependencies in the input sequences. In this paper, we present a literature review on Transformer-based (TB) models, providing a detailed overview of each model in comparison to the Transformer’s standard architecture. This survey focuses on TB models used in the field of Natural Language Processing (NLP) for textual-based tasks. We begin with an overview of the fundamental concepts at the heart of the success of these models. Then, we classify them based on their architecture and training mode. We compare the advantages and disadvantages of popular techniques in terms of architectural design and experimental value. Finally, we discuss open research, directions, and potential future work to help solve current TB application challenges in NLP.

Software architects cannot avoid the consideration of quality attributes when designing software architecture. Architectural styles such as Layers and Client-Server are often used by architects to describe the overall structure and behavior of software. Although an architectural style affects the achievement of quality attributes, these quality attributes are directly performed by design decisions called architectural tactics. While the implementation of an architectural tactic supports a specific quality attribute, it often enhances or hurts other quality attributes in the software. In this paper, a framework for selecting the most appropriate architectural tactics according to their best achievement of the required levels of quality attributes when developing transaction processing systems is proposed. The proposed framework is based on fuzzy measures using Choquet Integral approach and takes into account the impact of architectural tactics on quality attributes, the preferences of quality attributes and the interactions between them. It can also be used to compare different potential architectures in terms of their supporting of quality attributes. The abilities and the advantages of the proposed framework are clarified via practical experiments using a case study.

This work uses a coarse-grained FPGA architecture exploration environment to compare a column-based FPGA architecture with a non-column based architecture. Different groups of netlists are collected and a single floor-planning is optimized for all the netlists in a group. It has been found that the coarse-grained architectures that do not limit their hard-blocks to columns give much better placement costs and routing channel usage than the architectures that limit their hard-blocks to columns. Though a column based architecture can give a more compact layout as compared to a noncolumn based architecture; but the latter gives higher gains in the channel width requirements and can result in overall area gain.

With the remarkable development of grid technologies, many grid architectures have been proposed which have evolved greatly in recent years. One of the major challenges for grid technologies is to build the scientific and technological base for share, collaboration, large-scale distributed systems. Theories and models of grid architectures are crucial to this attempt as well as to underpinning the foundations for constructing grid systems working effectively. On the basis of a coarse-grain classification of grid applications, we present a novel taxonomy of grid architectures: interaction-intensive architecture and computation-intensive architecture. In this paper, two new grid performance metrics are proposed to measure performance of grid systems. Then, we model grid architectures mathematically via queueing system M/M/1 and M/M/1/K; mean waiting time and total spending time are given. Furthermore, we investigate the performance of two grid architectures and compare them with each other; meanwhile a series of simulations are carried out to demonstrate the analysis results. Finally, we obtain some scientific principles guiding the grid architecture design and optimization.

Since the beginning of the 21st century, a wave of innovative graphic architecture has emerged. However, these architectural works seem to have failed to inherit the profound aesthetics and sense of beauty associated with classical graphic architecture from history. Instead, they often exhibit superficial and exaggerated qualities, sparking widespread debate and criticism. This paper aims to integrate Immanuel Kant's aesthetic critique perspective, as presented in his work "Critique of Judgment," into the discourse on contemporary graphic architecture. By incorporating Kant's analyses and arguments regarding "agreeable," "beauty," and the "sublime" into discussions of contemporary architectural aesthetics, we seek to analyze and compare the similarities and differences between these new graphic architectural works and their classical predecessors. Ultimately, we arrive at the conclusion that these contemporary graphic architectural works, which often appear superficial and clichéd, are not deserving of admiration. At the same time, we propose recommendations for the design of future graphic architecture based on these insights.

The present work aims to analyze the relationship between sacred architecture and its relationship with place and time, demonstrating that even though the works are from different periods and authors, both have similar characteristics, which allows creating an opinion about the importance of religious architecture. As the sacred architecture had existed since the colonial period, it is intended to highlight its articulation with the national conjuncture, to then trace the history of the architects as well as the architectural styles. It is intended, after a bibliographical review, to compare the architecture between the styles as well as to identify religious architectural elements of a transitory or permanent character, the messages consolidated and perpetuated in time. As a solution, it is possible to diagnose that, despite different periods and authors, sacred architecture maintains its importance even in the face of the different architectural particularities located in time and space and that the essences of its message are sacred in people's lives.

Deep convolutional neural networks have been successfully applied to many image-processing problems in recent works. Popular network architectures often add additional operations and connections to the standard architecture to enable training deeper networks. To achieve accurate results in practice, a large number of trainable parameters are often required. Here, we introduce a network architecture based on using dilated convolutions to capture features at different image scales and densely connecting all feature maps with each other. The resulting architecture is able to achieve accurate results with relatively few parameters and consists of a single set of operations, making it easier to implement, train, and apply in practice, and automatically adapts to different problems. We compare results of the proposed network architecture with popular existing architectures for several segmentation problems, showing that the proposed architecture is able to achieve accurate results with fewer parameters, with a reduced risk of overfitting the training data.

the Convolution Neural Network (CNN) is the most widely used deep learning architecture as it has broken most world records for recognition tasks. Facial Expression Recognition (FER) systems that use classical feature- based techniques, especially CNN’s, is best for classifying images. This paper used three CNN-based methods, which are VGG-16, Inception-v3, and Resnet50-V2 network architectures, to classify facial expressions into seven classes of emotions: happy, angry, neutral, sad, disgust, fear, and surprise. The face expression dataset from Kaggle and JAFFE dataset were used to compare the accuracy between the three architectures to find the pretrained network that best classifies models. The results showed that VGG-16 network architecture produced a higher accuracy (93% in JAFFE and 54% in Kaggle) than the other architectures.

Phosphorelays are signal transduction circuits that sense environmental changes and adjust cellular metabolism. Five different circuit architectures account for 99% of all phosphorelay operons annotated in over 9,000 fully sequenced genomes. Here we asked what biological design principles, if any, could explain selection among those architectures in nature. We began by studying kinetically well characterized phosphorelays (Spo0 of Bacillus subtilis and Sln1 of Saccharomyces cerevisiae). We find that natural circuit architecture maximizes information transmission in both cases. We use mathematical models to compare information transmission among the architectures for a realistic range of concentration and parameter values. Mapping experimentally determined phosphorelay protein concentrations onto that range reveals that the native architecture maximizes information transmission in sixteen out of seventeen analyzed phosphorelays. These results suggest that maximization of information transmission is important in the selection of native phosphorelay architectures, parameter values and protein concentrations.

In the Distributed Management Task Force, DMTF, the management software in the Internet of things (IoT) should have five abilities including Fault Tolerance, Configuration, Accounting, Performance, and Security. Given the importance of IoT management and Fault Tolerance Capacity, this paper has introduced a new architecture of Fault Tolerance. The proposed hybrid architecture has used all of the reactive and proactive policies simultaneously in its structure. Another objective of the current paper was to develop a measurement indicator to measure the fault tolerance capacity in different architectures. The CloudSim simulator has been used to evaluate and compare the proposed architecture. In addition to CloudSim, another simulator was implemented that was based on the Pegasus-Workflow Management System (WMS) in order to validate the architecture that is proposed in this article. Finally, fuzzy inference systems were designed in a third step to model and evaluate the fault tolerance in various architectures. Based on the results, the positive effect of using various combined Reactive and Proactive policies in increasing the fault tolerance in the proposed architecture has been prominently evident and confirmed.

State-of-the-art video coding tools are submitted to severe performance and energy consumption requirements resulting from high complexity of video standards and from limited energy budgets of portable mobile devices. While providing most of the compression gains, inter frame and intra frame prediction techniques are the most demanding steps, since they compare a huge number of blocks. In such a process, the similarity metric employed affects both the quality of compression and the calculation effort. In this paper we propose the use of Hadamardbased Sum of Absolute Transformed Differences (SATD), in replacement of the traditionally used Sum of Absolute Differences (SAD), as a means of improving the efficiency of video coding. To allow that we explore two Hadamard Transform methods to design efficient SATD architectures, one using the Fast Hadamard Transform (FHT) butterfly and another one using the so-called Transform-Exempted (TE) SATD algorithm. Those methods were combined with architectural decisions (full parallelism, full parallelism with pipelining or multi-cycling) to build a total of six Hadamard-based SATD architectures that were synthesized for a commercial 45nm standard cell library for two operating frequencies. The architectures were simulated with pixel block data to obtain realistic dynamic power and energy estimates. The TE-SATD architectures achieved the lowest energy results: down to 13.13 pJ/SATD in the case of parallel architecture with pipeline. However, considering also the area results when evaluating energy, the best results are given by both methods using multi-cycling (transpose buffer): nearly 20.75 pJ/SATD with up to 63.54% smaller area compared with fully parallel architectures.

The Information Centric Networking ICN architectures are proposed to overcome the problems of the actual internet architecture. One of the main straight points of the ICN architectures is the in-network caching. The ICN performance is influenced by efficiency of the adopted caching strategy which manages the contents in the network and decides where caching them. However, the major issue which faces the caching strategies in the ICN architectures is the strategic election of the cache routers to store the data through its delivery path. This will reduce congestion, optimize the distance between the consumers and the required data furthermore improve latency and alleviate the viral load on the servers. In this paper, we propose a new efficient caching strategy for the Named Data Networking architecture NDN named NECS which is the most promising architecture between all the ICN architectures. The proposed strategy reduces the traffic redundancy, eliminates the useless replication of contents and improves the replay time for users due to the strategic position of cache routers. Besides, we evaluate the performance of this proposed strategy and we compare it with three other NDN caching strategies, using the simulator network environment NdnSIM. On the basis of the simulations carried out, we obtained interesting and convincing results.

The science of artificial intelligence and computer vision is beneficial in facilitating the detection of diseases in the medical field. Computer-based disease detection can save time. However, identifying and detecting tumors on MRI images require seriousness and is time-consuming. Due to the diversity of structures in size, shape, and intensity of the image, accuracy is needed in identifying the original organ structure and the diseased one. Previous studies have proposed a method for identifying brain tumors to produce the correct precision. In previous studies, neural network-based methods have good accuracy. We present five Convolutional Neural Network (CNN) architectures for identifying brain tumors (glioma, meningioma, no tumor, and pituitary) on MRI images. This study aims to develop an optimal CNN architecture for identifying tumors. We use the dataset from Kaggle with a total training data of 5712 and testing of 1311. Of the five proposed CNN architectures, architecture c has the highest accuracy of 82.2% with an unlimited number of parameters of 29605060. A good CNN architecture has many convolution layers. We also compare the proposed architecture with CNN transfer learning (Inception, ResNet-50, and VGG16), and with CNN transfer learning architecture, the accuracy is higher than our proposed architecture.

The typical architectural concepts of popular processor families, their features, advantages and disadvantages are considered. Examples of structures of known processors are given. Technical limitations for the further development of popular RISC (CISC) architectures in accordance with the von Neumann machine paradigm are outlined. Attention is drawn to the increase in the size of the hardware scheduler and the resulting shortage of space on the chip with an increase in the number of functional modules on cores with a “sequential” structure. The advantages of the VLIW concept and the compiler working with this architecture are described. To assess the effectiveness of the functioning of automated systems with various architectures, a number of synthetic tests were carried out and test programs were used. Performance measurements were carried out to compare electronic computers based on VLIW and x86-64 cores. A number of algorithms have been proposed to accelerate computational tasks of an automated system with a parallel structure. The need to apply the concept of parallel programming when refining existing and developing new software for modern automated systems is emphasized. An example of converting program code into a parallel structure is given to describe an algorithm for a sequential task, illustrating complex information connections.

In building software architectures, the relations between elements in different diagrams are often overlooked. The first stage of building IT systems is the use of ontology terminology, not software terminology, in the requirements engineering process. Then, when constructing software architecture, IT architects more or less consciously however introduce elements that represent the same classifier on different diagrams with similar names. These connections are called consistency rules and are usually not attached in any way in a modeling tool, and only a significant number of them in the models increase the quality of the software architecture. It is mathematically proved that the application of consistency rules increases the information content of software architecture. Authors show that increasing readability and ordering of software architecture by means of consistency rules have their mathematical rationale. In this article, we found proof of decreasing Shannon entropy while applying consistency rules in the construction of software architecture of IT systems. Therefore, it has been shown that marking selected elements in different diagrams with these same names is, therefore, an implicit way to increase the information content of software architecture while simultaneously improving its orderliness and readability. Moreover, this increase in the quality of the software architecture can be measured by entropy, which allows for checking whether the number of consistency rules is sufficient to compare different architectures, even of different sizes, thanks to entropy normalization, and checking during the development of the software architecture, what is the improvement in its orderliness and readability.

The Palace of Versailles was constructed in the enchanting city of Paris, while the majestic Yuanmingyuan was erected in the imperial capital of Beijing. Built during the same era, they serve as splendid exemplars of Western and Eastern royal gardens and architectural marvels respectively. The purpose of this paper is to compare the Palace of Versailles and the Imperial Garden Yuanmingyuan, two historic royal palaces, and discuss the differences in their construction background, planning layout, architectural style and garden features. Because of the disparity in the personalities of the two emperors, the palace possesses its own distinctive attributes. The Palace of Versailles is famous for its magnificent architecture and French gardens, which demonstrated the power and luxury of Louis XIV; the Yuanmingyuan, on the other hand, is famous for its unique Chinese garden style and exquisite architectural complex, which reflects Emperor Kangxis love and pursuit of traditional Chinese culture. By comparing the two palaces, we can better understand the differences in architecture and garden design across diverse cultural backgrounds, as well as their profound impact on architecture styles, landscaping techniques and cultural heritage.

Distributed quantum applications impose requirements on the quality of the quantum states that they consume. When analyzing architecture implementations of quantum hardware, characterizing this quality forms an important factor in understanding their performance. Fundamental characteristics of quantum hardware lead to inherent tradeoffs between the quality of states and traditional performance metrics such as throughput. Furthermore, any real-world implementation of quantum hardware exhibits time-dependent noise that degrades the quality of quantum states over time. Here, we study the performance of two possible architectures for interfacing a quantum processor with a quantum network. The first corresponds to the current experimental state of the art in which the same device functions both as a processor and a network device. The second corresponds to a future architecture that separates these two functions over two distinct devices. We model these architectures as continuous-time Markov chains and compare their quality of executing quantum operations and producing entangled quantum states as functions of their memory lifetimes, as well as the time that it takes to perform various operations within each architecture. As an illustrative example, we apply our analysis to architectures based on Nitrogen- Vacancy centers in diamond, where we find that for presentday device parameters one architecture is more suited to computation-heavy applications, and the other for networkheavy ones. We validate our analysis with the quantum network simulator NetSquid. Besides the detailed study of these architectures, a novel contribution of our work are several formulas that connect an understanding of waiting time distributions to the decay of quantum quality over time for the most common noise models employed in quantum technologies. This provides a valuable new tool for performance evaluation experts, and its applications extend beyond the two architectures studied in this work.

Abstract. Several studies have demonstrated the ability of long short-term memory (LSTM) machine-learning-based modeling to outperform traditional spatially lumped process-based modeling approaches for streamflow prediction. However, due mainly to the structural complexity of the LSTM network (which includes gating operations and sequential processing of the data), difficulties can arise when interpreting the internal processes and weights in the model. Here, we propose and test a modification of LSTM architecture that is calibrated in a manner that is analogous to a hydrological system. Our architecture, called “HydroLSTM”, simulates the sequential updating of the Markovian storage while the gating operation has access to historical information. Specifically, we modify how data are fed to the new representation to facilitate simultaneous access to past lagged inputs and consolidated information, which explicitly acknowledges the importance of trends and patterns in the data. We compare the performance of the HydroLSTM and LSTM architectures using data from 10 hydro-climatically varied catchments. We further examine how the new architecture exploits the information in lagged inputs, for 588 catchments across the USA. The HydroLSTM-based models require fewer cell states to obtain similar performance to their LSTM-based counterparts. Further, the weight patterns associated with lagged input variables are interpretable and consistent with regional hydroclimatic characteristics (snowmelt-dominated, recent rainfall-dominated, and historical rainfall-dominated). These findings illustrate how the hydrological interpretability of LSTM-based models can be enhanced by appropriate architectural modifications that are physically and conceptually consistent with our understanding of the system.

Learning by imitation is a natural and intuitive way to teach social robots new behaviors. While these learning systems can use different sensory inputs, vision is often their main or even their only source of input data. However, while many vision-based robot learning by imitation (RLbI) architectures have been proposed in the last decade, they may be difficult to compare due to the absence of a common, structured description. The first contribution of this survey is the definition of a set of standard components that can be used to describe any RLbI architecture. Once these components have been defined, the second contribution of the survey is an analysis of how different vision-based architectures implement and connect them. This bottom–up, structural analysis of architectures allows to compare different solutions, highlighting their main advantages and drawbacks, from a more flexible perspective than the comparison of monolithic systems.

Abstract The problem under consideration consists in choosing the number of k individuals, so that the time for processing k individuals by the genetic algorithm (GA) on the CPU architecture is close to the time for processing l individuals on the GPU architecture by the genetic algorithm. The initial information is data arrays containing information about the processing time of a given number of individuals by the genetic algorithm on the available hardware architectures. Fuzzy numbers are determined based on these arrays?~? and?~?, describing the processing time of a given number of individuals, respectively, on the CPU and GPU architectures. The peculiarities of the subject area do not allow considering the well-known methods of comparison based on the equalities of the membership functions and the nearest clear sets as adequate. Based on the known formula “close to Y (around Y)” the way to compare fuzzy numbers?~? and?~? was developed in order to determine the degree of closeness of the processing time of k and l individuals, respectively, on the hardware architectures of the CPU and GPU.

Abstract- Classical Indian architectural principles and traditions has been collected and preserved in a vast body of literature collectively known as the Vāstuśāstra. This branch of classical Indian knowledge is a realization of Hindu ideals in terms of architectural edifice, which significantly influence the religious architecture of the Indian cultural sphere which extends to the medieval Island of Java. Indian influence can be seen in Hindu temples of Java during the Śailendra’s dynasty even though some of it’s architectural elements can’t be found in vāstuśāstra. However, in contrast of Hindu’s vāstuśāstra, Buddhism has no architecture guideline and free standing structure as of sources that are used as it’s guide are questioned, especially Buddhist Temples in Central Java during ancient Mataram’s Dynasty of Śailendra. Although Buddha’s teachings and some parts of vāstuśāstra are known to play a role in the construction of Buddhist Temples in Indonesia, how far they are applied is difficult to observe, giving the absence of special studies and free standing temple references to build Buddhist Temple, and it’s interviewees are gone. By finding information about architecture’s theory of Buddha’s teachings that entered Indonesia and identify as well as compare the relevant parts of vāstuśāstra, then the architectural elements that are part of the concept of Buddha’s teachings and vāstuśāstra can be seen.In this research, descriptive method and qualitative approach are used by the author. The author focused in terms of figure and ornament as well as mass and spatial order. This research collects and compares parts of vāstuśāstra that are relevant as well as Buddha’s teachings concept to compare them with datas from the twelve samples of Buddhist Temples in Central Java during ancient Mataram’s Dynasty of Śailendra. Comparison by the author shows a number of results. Firstly, the concept of mahāyāna, vajrayāna, and mānasāra book applied in terms of figure, ornament, mass, and spatial order are seen in Central Java’s Buddhist Temples. However, various architectural details of these elements have marked differences from what is instructed in the Vāstuśāstra. The distinctive Javanese Kala-Makara for example, does not conform the mānasāra book. Secondly, the application of mānasāra book concepts in Central Java’s Buddhist Temples prove the influence of Hinduism which was affected by the harmonious relationship between Buddhism and Hinduism during that time. Lastly, the first free-standing Buddhist Temples is 5th Batujaya Temple/Blandongan Temple (2-3 CE and 7-10 CE) because the Mahabodhi Temple in India was built as we see today during the 6th restoration phase (8 CE).

Tree architecture models and the composition of vegetation types affected surface runoff and erosion rates due to vegetation density and various other morphological and ecological characteristic components. This research purpose was to measure and compare the level of erosion in 3 tree architectural models. The research used the path plots method. The sample pathway was made by cut off contour lines. To measure the erosion rate that occured at the tree architecture model, erosion measuring plots were used in three tree architecture models, namely Attims (Eucalyptus deglupta), Corner (Arenga pinnata), and Rauh (Arthocarpus teysmanii). The results showed that the dominant tree architecture model was the Rauh, Attims, and Corner models. The erosion level which occurred in the three tree architectural models showed that the Attims Eucalyptus deglupta model and Corner Arenga pinnata models were more effective in controlling erosion by 233.55 g/ha/year and 293.10 g/ha/year with rainfall of 493.55 mm compared to Rauh Arthocarpus teysmanii type. The correlation analysis between rainfall and the erosion rate at the three tree architecture models were 80% (very strong) for Attims model, 89% (very strong) for Corner model and 90% (very strong) for Rauh model. To control the erosion the Attims and Corner models are highly recommended as alternatives for rehabilitating the critical land.

Architecture has been considered one of the most expressive means for humans since the beginning of settlement. It carries two aspects, one of which is physical, which is the visible and tangible form. The other is non- physical, which is the intellectual content that the form reveals. Yemeni architecture in general and the architecture of temple gates in particular were shaped by the local environment and social culture. The Yemeni person tried to express his visions, beliefs, and perceptions in a unique architectural form that is distinct from others in an embodied and abstract form. The current research attempts to investigate the content that the architectural form of the Yemeni temple gates carried in form and details. The research focuses on tracing the relationship between the idea and the symbol of portal architecture from the stage of embodiment to the stage of abstraction. The research relies on descriptive and analytical approaches and comparative approaches to compare the gates with their counterparts in the kingdoms of ancient Yemen to determine the similarities and differences the extent of influence between the kingdoms. It aims to analyze the architectural form of the gate in a comprehensive and detailed manner to identify intellectual sources. The study reached an understanding of the architectural form of the temple gates and their contents. Yemeni thought was characterized by integration in embodiment and abstraction. The Yemeni architect turned to signs and symbols in order to give the form the character of embodiment through abstraction, while preserving the main features of the inspired form.

In contrast to other art groups, architecture not only shows the manifestation of one’s feelings and thoughts, but more importantly architecture serves to complement the needs of society. This is in line with the view of Ibn Khaldun who said that architecture is one of the characteristics of civilization that is a symbol of the glory of a nation or country. More and more buildings are developed and meet the needs of society show the progress of a civilization in this field. This article aims to sccrutinize the history of Islamic architectural writing in Malaysia in particular and compare the tendencies of the writers. Qualitative data were collected by using documentation methods and analysed by inductive, deductive and comparative methods. Findings exhibit those authors focused on the aesthetical values, designs and local genius in their works. It seems that uniformity in writing evolved unnoticed and writers inherited aspects of the discussion that had been initiated by previous scholars. In conclusion, similarities enhance uniformity in Islamic architectural writing in Malaysia

IoT is an enormous network of interconnected devices that gather data and share it over the internet. Today, IoT suffers from malevolent behaviours and actions that aim to damage and compromise privacy and security. Moreover, these issues and the new IoT requirements are not effectively covered by current architectures. Thus, this paper is an extended work of the authors' previous paper, which suggested a new architecture adhering to the IoT needs that have evolved. It suggests a hybrid architecture that integrates our previous one with a Blockchain-based architecture, to combine their significant features. The hybrid architecture fulfils the emerged requirements of IoT and exploits the Blockchain to increase trust, security and privacy. Further, the hybrid architecture delivers a novel structure to build the policy header, which is an access control list used to regulate the local network and was inherited from the Blockchain-based architecture. The Cooja simulator is used to compare the two structures, revealing that the new structure can use 87% less storage and 83% less computing.

This paper describes a comparison of two Montgomery modular multiplication architectures: a systolic and a multiplexed. Both implementations target FPGA devices. The modular multiplication is employed in modular exponentiation processes, which are the most important operations of some public-key cryptographic algorithms, including the most popular of them, the RSA. The proposed systolic architecture presents a high-radix implementation with a one-dimensional array of Processing Elements. The multiplexed implementation is a new alternative and is composed of multiplier blocks in parallel with the new simplified Processing Elements, and it provides a pipelined operation mode. We compare thetime×areaefficiency for both architectures as well as an RSA application. The systolic implementation can run the 1024 bits RSA decryption process in just 3.23 ms, and the multiplexed architecture executes the same operation in 4.36 ms, but the second approach saves up to 28% of logical resources. These results are competitive with the state-of-the-art performance.

The basis for the analysis is the developer's productivity. In a 3 year-long research and development project, a real-world telemedicine application was efficiently implemented four times with various software architectures and architectural patterns. More than 5,000 person-hours were spent on carrying out them. At present, a unique dataset is available, which provides the opportunity to compare the cost of spent person-hours in different approaches. The goal of this research is to describe the measurement approach, the dataset and the applied architectures considering the software developer's productivity.

_ This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper OTC 32317, “Fixed Wind Architecture Comparison for Offshore Green Hydrogen Production,” by Dominic Pliszka, Catherine Gourlay, and Nihad Abdullazada, Subsea7, et al. The paper has not been peer reviewed. Copyright 2023 Offshore Technology Conference. Reproduced by permission. _ The complete paper is a summary of a study that covers through-life economics for producing green hydrogen from offshore fixed wind turbines. The options compare production of hydrogen on the turbine itself (decentralized) with production on a dedicated production platform (centralized) and production from an onshore facility. The results of the economic analysis show that decentralized hydrogen production can be competitive against onshore production at longer offshore distances. Introduction The paper contains a summary of an offshore green-hydrogen-production study performed by a group of companies. The field architectures for each of the evaluated cases are described and the results of the economic analysis are presented in the complete text. Field Architecture Layouts The hydrogen production cases in the study are divided into three architectural layouts. Case 1: Onshore Hydrogen Production. The electricity produced at the offshore wind farm is gathered by interarray cables and directed to an offshore substation. From this location, the combined power is transported to an onshore hydrogen production facility through offshore export cables. Case 1 (the base case) is used to benchmark and compare the results against Cases 2 and 3. Case 2: Offshore Hydrogen Production (Decentralized). The electricity generated by each offshore wind turbine is directed to a hydrogen production unit specific to each of the turbines, and green hydrogen is produced. Hydrogen is collected and exported through a dedicated hydrogen transport line to onshore facilities. Case 2 also is referred to as a wind farm with a decentralized hydrogen production system. In this scenario, a gas compressor located on each wind turbine is considered. Case 3: Offshore Hydrogen Production (Centralized). The electricity produced at the offshore wind farm is directed to a hydrogen-production facility at a centralized offshore substation. The hydrogen from the substation is exported through a dedicated hydrogen transportation line to onshore facilities. This scenario is also referred to as a wind farm with centralized hydrogen production system. Wind-Farm Overview A single wind turbine with a maximum power output of 15 MW is assumed as the basis of this study. The wind farm has 67 turbines on fixed monopile foundations, giving a power rating of 1 GW. The wind turbines will be connected in a daisy-chain manner, each chain containing eight or nine turbines.
