This contribution sheds light on recent research efforts that pertain to the built environment in Indonesia. Within the rich diversity of cultures in the Nusantara archipelago interesting examples can be found that illustrate the adaptation to the challenging environmental conditions. Through this research the possibilities for sophisticated solutions for future are investigated, focusing on the building performance. Architecture and planning tasks in Indonesia have to consider the following preconditions: (i) The prevailing hot and humid climate, which will be strongly influenced by the climate change in the future; (ii) the country’s geography, which consists of a number of wide-spread islands; (iii) the rich and diverse historical development, including a very diverse architectural heritage; (iv) the location within the “Pacific Ring of Fire”, causing recurring natural disasters (e.g. volcano eruptions, earthquakes); (v) a currently ongoing rapid change in socioeconomic key data (economic growth rate, population growth, digitalization); (vi) a strong tendency to urbanization. Whereas these facts are known, as well as the need for energy efficient buildings, the level of knowledge about the performance of buildings in different regions of Indonesia is rather limited. Specifically, regional building traditions are often treated only in historical discourse. Thus, an interdisciplinary research effort that aims to examine Indonesian architecture in a comprehensive and holistic way has been undertaken in the past years, based on works dating back to 2005. In this paper we present parts of these efforts, namely (i) the assessment of a contemporary art museum in the city of Yogyakarta using monitored indoor conditions, and conception of potential future improvement; (ii) Further data collection efforts currently performed on a number of traditional residential buildings, (iii) a review of current, exemplary re-development efforts including the utilization and adaptation of traditional architectural concepts in Indonesia, and (iv) the details of the recently started incentive on interdisciplinary research on Indonesian architecture.

A highly reliable reverse-trapezoid-structured polydimethylsiloxane (PDMS) is demonstrated to achieve mechanically enhanced amorphous indium-gallium-zinc oxide (a-IGZO) thin-film-transistors (TFTs) for skin-compatible electronics. Finite element analysis (FEA) simulation reveals that the stress within a-IGZO TFTs can be efficiently reduced compared to conventional substrates. Based on the results, a conventional photolithography process was employed to implement the reverse-trapezoid homogeneous structures using a negative photoresist (NPR). Simply accessible photolithography using NPR enabled high-resolution patterning and thus large-area scalable device architectures could be obtained. The a-IGZO TFTs on the reverse-trapezoid-structured PDMS exhibited a maximum saturation mobility of 6.06 cm2V−1s−1 under a drain bias voltage of 10 V with minimal strain stress. As a result, the proposed a-IGZO TFTs, including stress-released architecture, exhibited highly enhanced mechanical properties, showing saturation mobility variation within 12% under a strain of 15%, whereas conventional planar a-IGZO TFTs on PDMS showed mobility variation over 10% even under a 1% strain and failed to operate beyond a 2% strain.

Northern highbush (NH) blueberry (Vaccinium corymbosum) and southern highbush (SH) blueberry (V. corymbosum hybrids) have fruit that vary in firmness. The SH fruit is mostly hand harvested for the fresh market. Hand harvesting is labor-intensive requiring more than 500 hours/acre. Rabbiteye blueberry (V. virgatum) tends to have firmer fruit skin than that of NH blueberry and has been mostly machine harvested for the processing industry. Sparkleberry (V. arboreum) has very firm fruit. With the challenges of labor availability, efforts are under way to produce more marketable fruit using machine harvesting. This could require changing the design of harvesting machine and plant architecture, and the development of cultivars with fruit that will bruise less after impact with hard surfaces of machines. The objectives of this study were to determine the fruit quality of machine-harvested SH blueberry, analyze the effect of drop height and padding the contact surface on fruit quality, investigate the effect of crown restriction on ground loss, and determine the effect of plant size on machine harvestability. The fruit of ‘Farthing’, ‘Scintilla’, ‘Sweetcrisp’, and several selections were either hand harvested or machine harvested and assessed during postharvest storage for bruise damage and softening. Machine harvesting contributed to bruise damage in the fruit and softening in storage. The fruit of firm-textured SH blueberry (‘Farthing’, ‘Sweetcrisp’, and selection FL 05-528) was firmer than that of ‘Scintilla’ after 1 week in cold storage. Fruit drop tests from a height of 20 and 40 inches on a plastic surface showed that ‘Scintilla’ was more susceptible to bruising than that of firm-textured ‘Farthing’ and ‘Sweetcrisp’. When the contact surface was cushioned with a foam sheet, bruise incidence was significantly reduced in all SH blueberry used in the study. Also, the fruit dropped 40 inches developed more bruise damage than those dropped 20 inches. Ground loss during machine harvesting was reduced from 24% to 17% by modifying the rabbiteye blueberry plant architecture. Further modifications to harvesting machines and plant architecture are necessary to improve the quality of machine-harvested SH and rabbiteye blueberry fruit and the overall efficiency of blueberry (Vaccinium species and hybrids) harvesting machines.

ABSTRACTA 6,13-Bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) based high-voltage organic thin film transistor (HVOTFT) has been demonstrated via a low temperature (< 100°C) solution-processed fabrication method on borosilicate glass. High-voltage is an area not well developed in the organic transistor field and can be of benefit to various applications requiring such an operating range beyond that of conventional thin film transistors. Here, our HVOTFT exhibited a mobility μ of 0.005 cm2 V-1 s-1 and a breakdown voltage of VDS > 120 V, the latter being due a space-charge limiting device architecture in which the channel is partially gated. Non-saturating I-V characteristic behavior was observed. This is in contrast with our vacuum-deposited pentacene HVOTFTs which exhibited breakdown voltages of VDS > 400 V. TIPS-pentacene was grown via a drop-casting deposition, with its crystallinity and grain size deduced under XRD and SEM analysis. The HVOTFT was fabricated with a dielectric stack of a high-k Bi1.5Zn1Nb1.5O7 (BZN) and parylene-C.

Research Highlights In this systematic review, we attempt to defend a view that the full potential of building information modelling (BIM) in enabling sustainable design and construction could transpire only through an in-depth understanding of every required component of BIM requirements across a construction project lifecycle. The findings from the study add to the body of literature by expanding the required components of BIM requirements through the amalgamation of variables that reside within the General Practitioners Information System (including IT infrastructure, process, people and environment) (Saleh and Alshawi, 2005) and the protocols for a BIM-collaborative design framework (including policy, process, and technology) (Kassem et al., 2014). The most striking result to emerge from the study is the process requirements of BIM. The fact that the accuracy and reliability of the information produced, shared, and reused across the construction project lifecycle may be affected without having a BIM process map and procedure for each of the BIM core activities being in place. Research Objectives Much of the discussion on BIM implementation centres on the required set of BIM requirements and specifications that should be delivered throughout a whole lifecycle of a project (Farzaneh, Monfet, & Forgues, 2019; Gao & Pishdad-Bozorgi, 2019; Ibrahim & Kingdom, 2013; Kamel & Memari, 2019; Parllaku & Underwood, 2017; Sacks, Gurevich, & Shrestha, 2016). Yet, very few studies have attempted to systematically review every aspect of BIM requirements from the perspective of policy, process, technology, environment and people-related interlocking pillars. The review by Farzaneh, Monfet, and Forgues (2019) and Kamel and Memari (2019) disregarded the legal and process aspects of BIM requirements and included only the technical requirements of BIM technology. In another review study, Sacks, Gurevich, and Shrestha (2016) drew conclusions from the review of BIM protocols, guides and standards and not from the existing emprical studies in supporting the emerging findings of BIM requirements obtained through the BIM-based documents. This gap necessitates the present study to holistically define the required components of BIM requirements by extending the base knowledge of BIM requirements as defined by Saleh and Alshawi (2005) and Kassem et al. (2014). Methodology The study employed PRISMA-P (Preferred Reporting Items for Systematic reviews and Meta-Analyses) (Moher et al., 2009) by first identifying related literature in the Web of Science, Scopus, and specific top-ranked journals covering BIM area of research. The following sets of keywords were used: (1) body of knowledge (including requirements, specifications and deliverables); (2) field area (including BIM, “building information modelling,” “building information model,” “building information modelling and management,” “collaborative BIM,” “integrated BIM,” “level 2 BIM,” and “level 3 BIM”) and (3) context (including organisation, firm, SMEs, industry, “construction industry,” AEC, macro, micro, and project). The initial search produced a list of 423 records, but 24 records were removed because of duplication. The remaining 399 articles were screened based on the following criteria, among others: publication types (research articles), language (English publications), and year (publication from 2005 to 2019). Finally, an eligibility screening was conducted to finalise the relevant literature for the qualitative thematic analysis. The total number articles finalised for analysis in ATLAS.ti 8 was 39. Results The review of the study uncovered five main pillars and 41 subpillars of BIM requirements throughout a whole lifecycle of a project. The six main pillars are process (P1) (16 subpillars), policy (P2) (7 subpillars), technology (P3) (6 subpillars), environment (P4) (6 subpillars), and people (P5) (6 subpillars). Process requirements of BIM have been the primary focus of previous studies (n=29), from which the following 16 subpillars emerged under the “process” pillar (P1): (i) benchmarking practices; (ii) BIM implementation plan; (iii) BIM model deliverables; (iv) BIM lifecycle process map; (v) BIM uses process map; (vi) BIM-information delivery manuals (IDM); (vii) COBIE; (viii) cost implementation plan; (viv) digital data management; (x) identification of project team’s capability; (xi) mobilisation; (xii) pilot project; (xiii) process flow redesign; (xiv) quality assurance; (xv) scoping activities and purpose and (xvi) risk management. Furthermore, majority of of the reviewed articles (n=25) discuss the policy pillar (P2) of BIM requirements, which further consist of the following seven subpillars: (i) BIM based documents; (ii) BIM execution plan; (iii) collaboration requirements; (iv) contractual documents; (v) employer information requirements; (vi) intellectual property and (vii) obligation of stakeholders. Meanwhile, sub-pillars including (i) BIM object library; (ii) collaboration server; (iii) ICT infrastructure; (iv) interoperability; (v) technical support and (vi) vendor evaluation have emerged across 23 studies under the technological requirements of BIM (P3). Also, in regard to the environment pillar (P4), the following six subpillars are discussed across 13 studies: (i) BIM research and development; (ii) incentives and reward; (iii) IT vison and mission; (iv) knowledge management; (v) organisational culture and (vi) senior leadership. Finally, the following six sub-pillars emerged within the people pillar (P5) of BIM requirements: (i) BIM competence; (ii) organisation experience; (iii) qualification; (iv) roles and responsibilities; (v) staff experience and (vi) training and education. Findings In can be concluded from the study that striking a balance between fulfilling the required components that reside within the process, policy, technology, environment, and people pillars of BIM requirements is crucial in achieving the full benefits of BIM adoption throughout a construction project lifecycle. Despite the policy and process requirements of BIM being the focus of discussion in previous studies, very few have attended to the investigation of people-related requirements of BIM, hence providing an avenue for further study. BIM adoption can no longer be viewed as a technological challenge but rather a strategy that requires organisational, managerial, and operational changes within the traditional practices. This shift would require the existing architectural, engineering and construction (AEC) industry players to equip themselves with different skill sets in order to remain competitive in the AEC industry sector.

In recent years, world blueberry (Vaccinium sp.) production has been split evenly between processing and fresh fruit markets. Machine harvest of highbush blueberry {northern highbush blueberry [NHB (V. corymbosum)], southern highbush blueberry [SHB (V. corymbosum interspecific hybrids)], and rabbiteye blueberry [RE (V. virgatum)]} typically has been used to obtain large volumes of fruit destined for processing. Because of financial and labor concerns, growers are interested in using machine harvesting for fruit destined to be fresh marketed. Bush architecture, harvest timing, loose fruit clusters, easy detachment of mature berries compared with immature berries, no stem retention, small stem scar, a persistent wax layer, and firm fruit are breeding goals to develop cultivars amenable to machine harvest. Progress in selecting for these traits has been made in existing highbush blueberry breeding programs, but will likely intensify as the need for cultivars suitable for machine harvest for the fresh market increases.

ABSTRACTLight-emitting diodes (LEDs) based on p-GaN/ZnO heterojunction were fabricated. GaN was deposited on sapphire using metal-organic chemical vapor deposition (MOCVD), and two kinds of ZnO i.e. ZnO thin film deposited by sputtering and ZnO nanorods (NRs) grown by hydrothermal method were used as n-type layer respectively. MgO film with the thickness around 10 nm was deposited by electron-beam deposition to act as an interlayer between GaN and ZnO. Photoluminescence, electroluminescence and I-V curves were measured to compare the properties of GaN based heterojunction LEDs with different architectures. The existence of MgO interlayer as well as the morphology of ZnO obviously influenced the electrical and optical properties of GaN based LEDs. The effect of MgO interlayer on ZnO growth, properties and I-V curves and emission spectra of LEDs is discussed in detail.

Form-finding has to be carried out for tensioned fabric structure in order to determine the initial equilibrium shape under prescribed support condition and pre-stress pattern. Tensioned fabric structures are normally designed to be in the form of equal tensioned surface. Tensioned fabric structure is highly suited to be used for realizing the surfaces of complex or new forms. However, the research study on a new form as a tensioned fabric structure has not attracted much attention. Alternative source of inspiration of minimal surface which could be adopted as form for tensioned fabric structure is very crucial. The aim of this study is to investigate initial equilibrium shape of tensioned fabric structures in the form of Handkerchief surface, u=v=0.2 and u=v=1.2. Experimental form-finding using soap film model is frequently used to develop the possible form of uniformly stressed surfaces. Apart from that, soap film model also provides a means for checking the accuracy of computational form-finding results. In this study, soap film model is used to investigate surface form corresponding to boundary shape defined by mathematical equation for minimal surface. Computational form-finding using nonlinear analysis method has been used in this study. The study proposes an alternative architectural surface for architect and structural engineer to consider Handkerchief surface, u=v=0.2 and u=v=1.2 applied in tensioned fabric structure. The results on factors affecting initial equilibrium shape can serve as a reference for proper selection of surface parameter for achieving a structurally viable surface. Such in-sight will lead the improvement of rural basic infrastructure, economic gains, sustainability of built environment and green technology initiative.

This project focuses on an ideal solution for restoring the roof of Notre-Dame in Paris, which burned down together with its spire on April 15, 2019. The main motive behind the design was to create a quiet space that will serve as a memorial of the fire and reflect the unity of the society that contributed to the rebuilding found. The primary step of the whole reconstruction is to find an adequate way of renewal and its ethical boundaries. Main attention is focused on the roof and on the spire of the cathedral. As a tribute to medieval builders who consecrated their lives into this magnificent piece of work. The exterior of the new design has the same silhouettes and proportions that it has got eight centuries ago, but with a touch of a modern day aesthetics. When designing the interior of the roof, it was really important to maintain a clear representation of Gothic architecture – the balance between darkness and light. The space is divided into two parts. The first part represents darkness, as an obstacle, which each of us has to overcome. The second part is full of natural light that seems to tear the roof of the cathedral and illuminates the entire space inside. At the heart of the design is a gem that matters the most, life. The spire of the cathedral is designed with four pillars that symbolize the connection of mind-spirit-body with physical world The idea of the spire reflects these seemingly different things, but together they unite into one piece.

The content of the work is ideas solution for the roof of the Notre-Dame in Paris, after the destroying fire in 2019. Main idea is to create garret space for spiritual people, which used to meet, study and pray without the contact with the tourists and fill in the gap after the old tower above the crossing. Concept based on the original garret, which was only for service. The idea is coming especially from the simplicity and effectivity of the old garret and pointing on some of his elements. Space under the roof should be simple according to the first floor of the cathedral. The function is reflecting simplicity of the spaces with the respect to historical cathedral. Garret is designed for spiritual people, who are working in Notre-Dame and makes a space for them, which will be calm place for meditation. For this purpose are there cells for individual studying, library, common space and chapel. Connecting and meeting point in the same time between the ground, garett and higher power is sanctuary. This part is getting light to the ground floor.

The topic of this thesis is architecture and settings of gothic horrors, particularly in films. The work explores the relationship between the genre of gothic horror and gothic architecture, mainly within examples of haunted castles. The aim of the work is to study in what way the haunted castles are depicted in films and how the gothic architecture is applied in their appearance. The thesis is divided in two parts. The first one is an analysis of some of the gothic horror tendencies which have an influence on the image of haunted castles. These can be observed in films as well as in literature and theatre since the beginnings of gothic horror in the second half of the 18th century until today. The second part uses these tendencies to analyse images of haunted castles in films Dracula (John Badham, 1979), Bram Stoker's Dracula (Francis Ford Coppola, 1992) and Van Helsing (Stephen Sommers, 2004).

The Agile/Virtual Enterprise (A/V E) model is considered a highly dynamic version of the Virtual Enterprise (VE) model, and its implementation presents several requirements in order to keep the VE partnership aligned with the market, i.e., with business. Such requirements include (1) the reduction of reconfiguration costs and effort, and (2) the capability to preserve the firms’ private knowledge on products or processes. These must be assured by a specific environment, or, in other words, by organizational infrastructures as a meta-organizational structure for VE design (or integration) and operation, such as the Market of Resources – an environment developed by the authors to cope with the highlighted requirements, and assuring a better performance than the traditional environments such as the Internet search engines or the electronic marketplaces. The Chapter describes the functionalities of the Market of Resources and explains how does it supports A/V E integration, and addresses some technologies that could support A/V E integration within the Market of Resources, namely XML/ebXML and Webservices. The Chapter proposes an architecture to support the operation of the Market of Resources, representing a fusion of the peer-to-peer (P2P) architecture with the client-server architecture, as a variant of P2P architecture. Also, a laboratory implementation of the web services for manufacturing is presented too.

The present topic is focused on the synthesis of bismuth oxide thin films on different substrates using the electrodeposition technique. Prepared samples were annealed at 573 K and further used for physical and electrochemical characterizations. The structural investigations of the prepared samples show polycrystalline nature with a tetragonal crystal structure. Morphological analysis shows spruce leaves with nano-rod-type architecture morphology. All samples show hydrophilic nature. Specimens for electrochemical analysis were scanned by CV in 1 M KOH on numerous scan rates, starting from 1 to 100 mV/s. The obtained maximum value of specific capacitance (SC) is 1742.79 F/gm. at a scan rate of 2 mV/s in 1 M KOH with a potential window (– 1.0 V to 0.8 V) vs. Ag/AgCl and acquired maximum value of specific energy and specific power was 56.68 Wh/Kg and 2.94 kW/kg at 10 mA/cm2 . The Nyquist plot shows the internal resistance of the optimized electrode. The final optimized sample will be used for the energy storage supercapacitor application.

Efficient navigation is a challenge for visually impaired people. Several technologies combine sensors, cameras, or feedback chan-nels to increase the autonomy and mobility of visually impaired people. Still, many existing systems are expensive and complexto a blind person’s needs. This work presents a dataset for indoornavigation purposes with annotated ground-truth representingreal-world situations. We also performed a study on the efficiencyof deep-learning-based approaches on such dataset. These resultsrepresent initial efforts to develop a real-time navigation systemfor visually impaired people in uncontrolled indoor environments.We analyzed the use of video-based object recognition algorithms for the automatic detection of five groups of objects: i) fire extin-guisher; ii) emergency sign; iii) attention sign; iv) internal sign, and v) other. We produced an experimental database with 20 minutesand 6 seconds of videos recorded by a person walking throughthe corridors of the largest building on campus. In addition to thetesting database, other contributions of this work are the study onthe efficiency of five state-of-the-art deep-learning-based models(YOLO-v3, YOLO-v3 tiny, YOLO-v4, YOLO-v4 tiny, and YOLO-v4scaled), achieving results above 82% performance in uncontrolledenvironments, reaching up to 93% with YOLO-v4. It was possible toprocess between 62 and 371 Frames Per Second (FPS) concerning thespeed, being the YOLO-v4 tiny architecture, the fastest one.
