Abstract:

LED building means that the LED screen covers building surface mostly, which could real-time reflect information, while forgetting the concept of “wall”. The information materialized itself. At the same time, information approaches the relationship between the architects and the popularity, so that confuses the difference. The space will not “be pushed” by the architects, while “being fetched” by the popularity. This visual space not only “analogs”, “translates”, or “amplifies” the real images, but also the other kind of existence. Virtual building expands the controlling mode in the physical world. It is a new way of travel, communication, control, and express. With the development of popular consuming culture and visual culture, and the exploring of LED expression and development of virtual technology by architects and artists, the LED buildings and virtual buildings will the indispensable existence with us. As a new kind of architectural design innovation, will they reveal the future the architecture development?

Abstract:

Anticipating pedestrian crossing behavior in urban scenarios is a challenging task for autonomous vehicles. Early this year, a benchmark comprising JAAD and PIE datasets have been released. In the benchmark, several state-of-the-art methods have been ranked. However, most of the ranked temporal models rely on recurrent architectures. In our case, we propose, as far as we are concerned, the first self-attention alternative, based on transformer architecture, which has had enormous success in natural language processing (NLP) and recently in computer vision. Our architecture is composed of various branches which fuse video and kinematic data. The video branch is based on two possible architectures: RubiksNet and TimeSformer. The kinematic branch is based on different configurations of transformer encoder. Several experiments have been performed mainly focusing on pre-processing input data, highlighting problems with two kinematic data sources: pose keypoints and ego-vehicle speed. Our proposed model results are comparable to PCPA, the best performing model in the benchmark reaching an F1 Score of nearly 0.78 against 0.77. Furthermore, by using only bounding box coordinates and image data, our model surpasses PCPA by a larger margin (F1=0.75 vs. F1=0.72). Our model has proven to be a valid alternative to recurrent architectures, providing advantages such as parallelization and whole sequence processing, learning relationships between samples not possible with recurrent architectures.

Abstract:

Building a large-scale Mach-Zehnder-based silicon photonic switch circuit (LS-MZS) requires an appropriate choice of architecture. In this work, we propose, for the first time to our knowledge, a single metric that can be used to compare different topologies. We propose an accurate analytical model of the signal-to-crosstalk ratio (SCR) that highlights the performance limitations of the main building blocks: Mach-Zehnder interferometers (MZI) and waveguide crossings. It is based on the cumulative crosstalk and total insertion loss of the LS-MZS. Four different architectures: Beneš, dilated Beneš, switch and select, double-layer network were studied for the reason that they are mainly referenced in the literature. We compared them using our developed SCR indicator. With reference to the state-of-the-art technology, the analysis of the four architectures using SCR showed that, on a large scale, a high number of waveguide crossings significantly affects the performance of the switch matrix. Moreover, better performance was reached using the double-layer-network architecture. Then, we presented a 2 × 2 MZI using two electro-optic phase shifters and a waveguide crossing realized in LETI’s silicon photonics technology. Measured performances were quite good: the switch circuit had a crosstalk of −31.3 dB and an insertion loss estimated to be less than 1.31 dB.

Full text

Abstract:

Based on non-crossing relations, vertical constraint relations and net-geometry relations in one T-type junction region, two kinds of routability crossing distributions are proposed to improve routing performance in one T-type junction region. For routability crossing distribution in one T-type junction region, a routability-ordering graph is built to decide a net ordering in O(n2) time. For routability quota crossing distribution in one T-type junction region, if the number of net crossings in base channel is more than a given quota, this net ordering in routability crossing distribution will be further adjusted to satisfy the quota requirement by using a net interchange operation in O(n) time. For floating pin assignment in one T-type junction region, global nets are assigned on the boundary between top channel and base channel by interleaving vacant pins in O(n) time according to a net ordering in routability crossing distribution.

Abstract:

This paper uses the case of the exquisite design Yaring palace as a framework and springboard to discuss the particularities of the design language of the Pattani palace and architecture. The region of Pattani represents a unique crossing between a Thai identity and a Malay identity in terms of architecture. Because of its geographic position, both Asian identities merge into a language of regionalism syncretism that creates a rich blend of architectural expression representative of a South East Asian language. The paper discusses its facade expression, ornamentation, layout and interior design elements.

Abstract:

For mobile robots navigating on sidewalks, the ability to safely cross street intersections is essential. Most existing approaches rely on the recognition of the traffic light signal to make an informed crossing decision. Although these approaches have been crucial enablers for urban navigation, the capabilities of robots employing such approaches are still limited to navigating only on streets that contain signalized intersections. In this article, we address this challenge and propose a multimodal convolutional neural network framework to predict the safety of a street intersection for crossing. Our architecture consists of two subnetworks: an interaction-aware trajectory estimation stream ( interaction-aware temporal convolutional neural network (IA-TCNN)), that predicts the future states of all observed traffic participants in the scene; and a traffic light recognition stream AtteNet. Our IA-TCNN utilizes dilated causal convolutions to model the behavior of all the observable dynamic agents in the scene without explicitly assigning priorities to the interactions among them, whereas AtteNet utilizes squeeze-excitation blocks to learn a content-aware mechanism for selecting the relevant features from the data, thereby improving the noise robustness. Learned representations from the traffic light recognition stream are fused with the estimated trajectories from the motion prediction stream to learn the crossing decision. Incorporating the uncertainty information from both modules enables our architecture to learn a likelihood function that is robust to noise and mispredictions from either subnetworks. Simultaneously, by learning to estimate motion trajectories of the surrounding traffic participants and incorporating knowledge of the traffic light signal, our network learns a robust crossing procedure that is invariant to the type of street intersection. Furthermore, we extend our previously introduced Freiburg Street Crossing dataset with sequences captured at multiple intersections of varying types, demonstrating complex interactions among the traffic participants as well as various lighting and weather conditions. We perform comprehensive experimental evaluations on public datasets as well as our Freiburg Street Crossing dataset, which demonstrate that our network achieves state-of-the-art performance for each of the subtasks, as well as for the crossing safety prediction. Moreover, we deploy the proposed architectural framework on a robotic platform and conduct real-world experiments that demonstrate the suitability of the approach for real-time deployment and robustness to various environments.

Abstract:

The Cathedral of Noyon houses the most unusual—and largely unknown—installation of acoustic vases in Western Europe, the caveau phonocamptique, a chamber installed beneath the pavement of the crossing. Acoustic vases are simple earthenware pots placed in the walls and vaults of postclassical churches, their installation inspired by Marcus Vitruvius Pollio's De architectura libri decem. In Acoustics at the Intersection of Architecture and Music: The Caveau Phonocamptique of Noyon Cathedral, Andrew Tallon investigates the intended operation of the caveau as a monumental amplifier. According to the principle of conservation of energy, the effect of an acoustic vase can only be one of absorption, but when sung directly into, a vase appears to “sing back.” Tallon asserts that this effect, along with the importance of Vitruvius as the foremost authority on ancient architecture known to European builders and patrons, must ultimately account for this unique array at Noyon.

Full text

Abstract:

In architecture, atmosphere and its many implications have, in recent years, received increased attention. This paper considers atmosphere in architectural representation, and begins with an exploration of different definitions of these atmospheric representations. This paper then identifies and summarises representations of atmosphere in architecture and their key aspects, and proposes, in the form of a timeline, a preliminary systematisation of these aspects. This paper considers both traditional and digital representations of atmosphere in architecture, and focuses on aesthetic and emotional qualities of atmosphere. Thus, this paper is not limited to realistic and scientific approaches of atmosphere as meteorological conditions, but extends to atmosphere as emotions and mood. This paper also suggests cross-fertilisation, in the representation of atmosphere, between architecture and other fields. Therefore, while this paper explores atmospheric representations in architecture, it establishes its discussions by crossing disciplinary boundaries. It is anticipated that this paper will encourage further research, including recommendations for negotiating the apparent incompatibility of traditional and digital representations, to maintain qualities characterising well-known examples from the past.

Full text

Abstract:

A common approach used for planning blind intersection crossings is to assume that hypothetical vehicles are approaching the intersection at a constant speed from the occluded areas. Such an assumption can result in a deadlock problem, causing the ego vehicle to remain stopped at an intersection indefinitely due to insufficient visibility. To solve this problem and facilitate safe, deadlock-free intersection crossing, we propose a blind intersection planner that utilizes both the ego vehicle and the approaching vehicle’s visibility. The planner uses a particle filter and our proposed visibility-dependent behavior model of approaching vehicles for predicting hidden vehicles. The behavior model is designed based on an analysis of actual driving data from multiple drivers crossing blind intersections. The proposed planner was tested in a simulation and found to be effective for allowing deadlock-free crossings at intersections where a baseline planner became stuck in a deadlock. The effects of perception accuracy and sensor position on output motion were also investigated. It was found that the proposed planner delayed crossing motion when the perception was imperfect. Furthermore, our results showed that the planner decelerated less while crossing the intersection with the front-mounted sensor configuration compared to the roof-mounted configuration due to the improved visibility. The minimum speed difference between the two sensor configurations was 1.82 m/s at an intersection with relatively poor visibility and 1.50 m/s at an intersection with good visibility.

The experience of the exhibition On the Surface – a retrospective of the work of Metis, the Edinburgh-based atelier of Mark Dorrian and Adrian Hawker, presented in the exhibition space of The Aarhus School of Architecture – is choreographed as a walk over superimposed fragments of architectural representations. This action of walking, of following the drawing on the ground, enables the erasure of the specific time/place chronotopes of the seven exhibited projects, allowing new itineraries to be drawn through the crossing of this complex context.

Abstract:

Views on architecture that hold a significant position in architectural theory are the ones by Marc-Antoine Laugier, a French theoretician from the 18th century. The research on his architectural theory that have been carried out so far are quite stereotypical and concern Laugier?s concept of primitive hut as his only significant contribution to architectural theory. It is well-known that the concept of primitive hut plays an important role in Laugier?s theory and it is what actually maintained his reputation up to now. However, by singling out this concept as an independent one, one actually neglects all the other aspects of Laugier?s theory. The aim of this paper is to present multidimensionality of Laugier?s architectural aesthetics by crossing the borders of architecture and viewing Laugier?s ideas in cultural, philosophical, religious and historical context, as well as applying the integrative process and considering the spiritual paths of the enlightenment movement in the mid-18th century. A special attention is paid to considering the aesthetic aspect which represents the gist and an inevitable part of Laugier?s architectural theory. His aesthetic theory is important in forming the classicist style, and despite its radical character, it influenced many architects in France and the rest of Europe. We may see Laugier as one of the first modernists considering his structuralist logic of the constructive circuit of architecture and aesthetic modesty of decoration. Laugier?s functionalist attitude that the constructive circuit should at the same time represent a decorative element of architecture confirms the thesis that modernist approach has its roots in the 18th century.

Abstract:

Modularization is a strategy used for handling the demand for external complexity with less internal complexity, which leads to higher profits and more efficient product development processes. However, modularity is often driven in silos, not crossing into the engineering fields of mechanics, electronics, and software. Therefore, we present the MESA (Mechanics, Electronics, and Software Architecture) tool—a tool that can be used to visualize modular product architectures across mechanics, electronics, and software. The tool demonstrates how a change in one domain affects the rest and how well aligned the modularity in the different domains is. The tool has been tested in two case companies that were used for case application and has helped provide information for making key design decisions in the development of new product families.

Abstract:

The article provides a comprehensive architectural and historical-geographical analysis of a unique monument of medieval religious-defensive architecture – the Church of the Assumption of the Virgin in Vasilcau village, located on the banks of the Dniester River, near the state border of the Republic of Moldova and the Ukraine. Vasilcau was the border point between the Principality of Moldavia and the Grand Duchy of Lithuania in the Middle Ages. Its geographical position led to the formation of a fortified border point here, which served as an eastern outpost of the Soroca tsinut (county). The elevated cape with steep slopes, on which a temple with a bell tower, a courtyard, a trading square, as well as an ancient trade road and a river crossing was built, is a vivid example of a natural, historical-cultural complex, the basis of which is a medieval fortified point with a unique cult-defensive monument of architecture. The church represents a widespread type of place of worship, whose architecture combines the planimetric features of wooden architecture with those used in medieval buildings built of stone, highlighted in the found proportions. The solution of the historical-geographical enigmas that envelop the history of the heritage monument in the absence of written sources is carried out on the basis of a complex poly-scale historical and cartographic analysis and the use of modern geoinformation methods.

Abstract:

High Victorian Gothic in England was an exotic style, and the importance of Italian Gothic precedents in its development has long been recognized, as has the interest in thirteenth-century French Gothic in the 1850s. What has received much less attention is the influence of the medieval buildings of Normandy. In this article, I examine the historical and cultural connections between England and Normandy, which were stimulated by the Napoleonic Wars and the threat of invasion, and were further encouraged by the ease of crossing the English Channel. Seeking the origins of English Gothic and Romanesque architecture, antiquaries and artists explored Normandy in the decades after Waterloo, anticipating the interest of architects. Whether the results of travel or study of a growing number of publications on the medieval architecture of Normandy, numerous midcentury buildings show intimate acquaintance with thirteenth-century churches in Normandy-old village churches with saddleback towers or distinctive spires, which, paradoxically, resemble High Victorian designs in their rugged austerity.

Full text

Abstract:

This paper shows that autonomous implicit ODEs (based on planar lemniscates) are interesting models, yielding pinched self-crossing hystereses that are intrinsic features of all memristive elements in nanoscale electronics. Each model has a folded saddle that allows for an oscillating trajectory to traverse different sides of singularity. The models considered in this paper are autonomous and therefore different from typical input–state–output models considered thus far. The models preserve the usual properties of memristive elements. For example, the area enclosed by the pinched hystereses decreases with the increased frequency of oscillations. The same-time instant zero-crossing property is also satisfied provided that certain conditions are met. Another novel aspect of this paper is the fact that the autonomous models are based on various planar lemniscates (of Gerono, Devil and Bernoulli) which can be nonlinearly transformed to model pinched hystereses of various shapes. The proposed models are differentiable and the use of the sign and absolute value terms, typical in modeling of memristive elements, is avoided. Several simulation results are included and two simple analog circuits having the pinched hysteretic characteristics of mem-inductors and mem-capacitors are proposed.

Abstract:

One of the main problems for CSG models manipulators is the fast visualization of the results. The high computational cost on single-processor architectures makes the CSG scheme useless for the interactive creation of the model. This article deals with a parallel algorithm based on general purpose SIMD architecture, such as the Connection Machine 2, for the visualization of high quality shaded images of CSG models in nearly real time. The technique is based on a pixels parallelization of the Ray Casting algorithm. The Frame Buffer is divided into severals regions and for each of them we determine the CSG reduced model projected on it. Then a processor is assigned to each pixel in the sub-area; it determines the equation of the ray crossing the pixel and, using the Ray Casting technique, the nearest intersection point to the pixel on which it calculates the illumination model.

Abstract:

This paper studies the planning of conflict-free and efficient crossings of antagonistic vehicles’ movements at lightless intersections. A fully automated infrastructure environment is considered, where all vehicles that enter the intersection area are connected and automated (CAVs), i.e., they are equipped with advanced communication and automation technologies. In such a futuristic environment, traffic lights that regulate the right-of-way of different traffic streams are obsolete because of vehicle communication capabilities. The connectivity is utilized to derive vehicle trajectories such that a safe and efficient crossing of lightless intersections is possible. So far, published studies lack the application to complex intersection layouts. To fill this gap, we introduce a control method for CAV pairing allowing for the safe, collision-free crossing of the intersecting area and optimize traffic conditions, i.e., total delays of the system. Simulation results demonstrate the feasibility and applicability of the presented approach, given that all the technical specifications (e.g., communications, velocity actuators) are present. Finally, we conduct a sensitivity analysis for the algorithm’s main parameters, which provides practical insights for the studied experimental scenarios and other existing algorithms in the literature that tackle this problem.

Abstract:

The switch and crossing (S&C) is one of the most important parts of the railway infrastructure network due to its significant influence on traffic delays and maintenance costs. Two central questions were investigated in this paper: (I) the first question is related to the feasibility of exploring the vibration data for wear size estimation of railway S&C and (II) the second one is how to take advantage of the Artificial Intelligence (AI)-based framework to design an effective early-warning system at early stage of S&C wear development. The aim of the study was to predict the amount of wear in the entire S&C, using medium-range accelerometer sensors. Vibration data were collected, processed, and used for developing accurate data-driven models. Within this study, AI-based methods and signal-processing techniques were applied and tested in a full-scale S&C test rig at Lulea University of Technology to investigate the effectiveness of the proposed method. A real-scale railway wagon bogie was used to study different relevant types of wear on the switchblades, support rail, middle rail, and crossing part. All the sensors were housed inside the point machine as an optimal location for protection of the data acquisition system from harsh weather conditions such as ice and snow and from the ballast. The vibration data resulting from the measurements were used to feed two different deep-learning architectures, to make it possible to achieve an acceptable correlation between the measured vibration data and the actual amount of wear. The first model is based on the ResNet architecture where the input data are converted to spectrograms. The second model was based on a long short-term memory (LSTM) architecture. The proposed model was tested in terms of its accuracy in wear severity classification. The results show that this machine learning method accurately estimates the amount of wear in different locations in the S&C.

Abstract:

Abstract The Sivas basin (Turkey) shows pronounced salt tectonics activity involving the Oligocene evaporites. Despite the complete exposure of the structures, the tectonic evolution of the basin has been so far misunderstood because it has only been envisioned in a context of thrust tectonics. The core of the basin, a 35×25 km area, displays rounded minibasins separated by evaporitic walls, and partially covered by remobilized gypsum (either sedimentary or flowage). The minibasins are filled by Mid-Oligocene to Early Miocene clastics (fluvial silts and sandstones), marls, and lacustrine to marine limestones, the thickness of which may reach 4 kilometres. The stratal architecture along evaporite walls records the progressive subsidence of the minibasins, with strong rotation of beds, unconformities and local reworking of evaporites. Within the basin, the sediments show lateral thickness variations and spectacular angular unconformities. The observed geometries show striking similarities with the seismic data from petroleum basins suffering strong salt tectonism (gulf of Mexico, Precaspian basin, Angolan margin).

Abstract:

Privacy protection has recently been in the spotlight of attention to both academia and industry. Society protects individual data privacy through complex legal frameworks. The increasing number of applications of data science and artificial intelligence has resulted in a higher demand for the ubiquitous application of the data. The privacy protection of the broad Data-Information-Knowledge-Wisdom (DIKW) landscape, the next generation of information organization, has taken a secondary role. In this paper, we will explore DIKW architecture through the applications of the popular swarm intelligence and differential privacy. As differential privacy proved to be an effective data privacy approach, we will look at it from a DIKW domain perspective. Swarm intelligence can effectively optimize and reduce the number of items in DIKW used in differential privacy, thus accelerating both the effectiveness and the efficiency of differential privacy for crossing multiple modals of conceptual DIKW. The proposed approach is demonstrated through the application of personalized data that is based on the open-source IRIS dataset. This experiment demonstrates the efficiency of swarm intelligence in reducing computing complexity.

Abstract:

Abstract. This study focuses on detecting vehicle crossings (events) with ground-based interferometric radar (GBR) time series data recorded at bridges in the course of critical infrastructure monitoring. To address the challenging event detection and time series classification task, we rely on a deep learning (DL) architecture. The GBR-displacement data originates from real-world measurements at two German bridges under normal traffic conditions. As preprocessing, we only apply a low-pass filter. We develop and evaluate a one-dimensional convolutional neural network (CNN) to achieve a solely data-driven event detection. As a baseline machine learning approach, we use a Random Forest (RF) with a selected feature-based input. Both models’ performance is evaluated on two datasets by focusing on identifying events and pure bridge oscillations. Generally, the event classification results are promising, and the CNN outperforms the RF with an overall accuracy of 94.7% on the test subset. By relying on an entirely unknown second dataset, we focus on the models’ performances regarding the distinction between events and decays. On this dataset, the CNN meets this challenge successfully, while the feature-based RF classifies the majority of non-event decays as events. To sum up, the presented results reveal the potential of a data-driven DL approach concerning the detection of bridge crossing events in GBR-based displacement time series data. Based on such an event detection, a prospective assessment of bridge conditions seems feasible as an extension to previous structural health monitoring approaches.

A smart antenna using 4x4 Butler matrix for 5.8 GHz band is designed. The antenna array has four inputs and is excited by the Butler matrix feeding network to electronically steer the beams in desired directions. The architecture of the Butler matrix beamforming network is designed without using cross couplers, in fact the array antenna will be surrounded by the hybrid couplers, and it leads to decrease losses due to the crossing lines. The designed prototype is simulated on Rogers RT /duroid 5880 substrate with a relative permittivity of 2.2 using ADS momentum software.

Abstract:

A linear analog network model is proposed to characterize the function of the outer retinal circuit in terms of the standard regularization theory. Inspired by the function and the architecture of the model, a vision chip has been designed using analog CMOS Very Large Scale Integrated circuit technology. In the chip, sample/hold amplifier circuits are incorporated to compensate for statistic transistor mismatches. Accordingly, extremely low noise outputs were obtained from the chip. Using the chip and a zero-crossing detector, edges of given images were effectively extracted in indoor illumination.
