The future of wheat production depends on our ability to adapt to changing growing conditions. It is expected that intercropping will be more emphasized where natural source of nitrogen may increase the resilience of cereals. Our investigation was made in two growing seasons (2020–2021, 2021–2022) with three winter wheat varieties (GK Szilárd, Cellule, GK Csillag) and a winter pea variety (Aviron) in Szeged-Öthalom. Each plot was 10 square meters in four repeats in randomized block design. We used a seed mixture of both species with three sowing densities. In this study, we represent a development process of two winter-sown species, then yield components evaluated by cumulative yield production analysis and multivariate regression. Mixtures were only beneficial for wheat in the case of GK Szilárd 50% and Aviron 75%, Cellule 75% and Aviron 100% (in 2021), Cellule 100% and Aviron 50% (in 2022), GK Csillag 75% and Aviron 50%. The yield was determined by the number and weight of grains in both species (and also number of pea pods). Knowledge of the development process of the companion plants is a key issue in creating an effective intercrop. This self-sustaining, low input and energy efficient cropping practice has a great potential in temperate areas.

Diseñar formas y espacios de aprendizaje es un proceso que requiere creatividad pedagógica, arquitectónica, social, cultural y política.La literatura científica nacional e internacional (OCDE, 2017) sobre innovación educativa destaca la estrecha relación que conecta la didáctica con el entorno de aprendizaje. Por ello, los procesos de renovación educativa no pueden prescindir de una nueva visión de los espacios escolares y de los entornos educativos.Surgen nuevas pautas de planificación escolar, se enfatiza el aprendizaje como un proceso activo y constructivo en el que cada niño tiene un papel «protagonista».De hecho, en el escenario contemporáneo, los estudiantes se convierten en participantes activos en la creación de información y nuevas ideas en el entorno educativo. En consecuencia, la educación del siglo XXI se basa en tres principios pedagógicos (McLoughlin & Lee, 2008): personalización, participación y productividad (Luna Scott, 2015).El estudio de estos aspectos, acompañado del análisis evaluativo y comparativo de experiencias de diseño en el ámbito escolar, nos ha permitido configurar el nuevo concepto SINAPSI 0-14, un sistema de mobiliario que adapta y adopta tecnologías avanzadas para satisfacer las necesidades de los niños y profesores, actuales y futuras, según una perspectiva holística.El objetivo era diseñar un sistema de celdas «orgánicas» modulares, flexibles y adaptables que pudieran ser utilizadas de forma transversal por usuarios de diferentes edades, desde jardines de infancia hasta centros de enseñanza primaria y secundaria. SINAPSI 0-14 se configura en formas que pertenecen a un universo de geometrías que se remontan a una única matriz de elementos orgánicos. El conjunto de símbolos que pueden agregarse definen diferentes formas del sistema de mobiliario, haciendo que el espacio educativo sea «cronotópico» y capaz de cambiar según el tiempo y el lugar que se cree y según el uso y las necesidades.Estos estudios en profundidad han permitido reconstruir un repertorio analítico crítico sobre el tema de los espacios educativos y la arquitectura escolar, entrelazando sus cambios en función de los modelos pedagógicos y los instrumentos normativos, para definir la escuela del futuro. Progettare forme e spazi di apprendimento è un processo che richiede creatività pedagogica, architettonica, sociale, culturale e politica.La letteratura scientifica nazionale e internazionale (OECD, 2017) sull’innovazione educativa evidenzia la stretta relazione che connette la didattica all’ambiente di apprendimento. Per tale ragione, i processi di rinnovamento della didattica non posso prescindere da una nuova visione degli spazi scolastici e dei setting educativi.Emergono nuove linee guida per la progettazione scolastica, si enfatizza l’apprendimento come un processo attivo e costruttivo nel quale ogni bambino ha un ruolo di “protagonista”.Difatti, nello scenario contemporaneo, gli studenti divengono partecipanti attivi alla creazione di informazioni e di nuove idee nell’ambiente educativo. Di conseguenza, l'istruzione del ventunesimo secolo si basa su tre principi pedagogici (McLoughlin & Lee, 2008): personalizzazione, partecipazione e produttività (Luna Scott, 2015).Lo studio di tali aspetti, accompagnato dall’analisi valutativa e comparativa di esperienze progettuali in campo scolastico, ha consentito di configurare il nuovo concept allestitivo SINAPSI 0-14, un sistema d’arredo che adatti e adotti le avanzate tecnologie per rispondere ai bisogni di bambini e insegnanti, attuali e futuri, secondo una prospettiva olistica.L’obiettivo è stato progettare un sistema di cellule “organiche” modulari, flessibili e adattabili che possano essere utilizzate in maniera trasversale da utenti di diverse età, dalle scuole d’infanzia alle scuole primarie e secondarie di primo grado. SINAPSI 0-14 si configura in forme appartenenti a un universo di geometrie riconducibili a un’unica matrice di elementi organici. L’insieme dei simboli aggregabili definiscono differenti forme del sistema di arredo rendendo lo spazio didattico “cronotopico” atto a modificarsi in funzione del tempo e del luogo che si crea e in funzione dell’uso e delle esigenze.Tali approfondimenti hanno consentito di ricostruire un repertorio critico analitico sul tema degli spazi educativi e delle architetture scolastiche intrecciandone i cambiamenti in linea con i modelli pedagogici e gli strumenti normativi, al fine di definire la scuola del futuro.

Quantum-dot cellular automata (QCA) is an emerging nanotechnology that promises faster speed, smaller size, and lower power consumption compared to the transistor-based technology. Moreover, XOR is a useful component for the design of many logical and functional circuits. This paper proposes a novel and efficient QCA XOR design. The proposed XOR design has been compared to a few recent designs in terms of area, speed and complexity. Comparison of results illustrates significant improvements in our design as compared to traditional approaches. Also simulation proves that the proposed XOR design is completely robust and more sustainable to high input frequency as compared to other designs. This robustness is highly significant when this component is applied for realizing larger designs.

This article shows how a good understanding of the design principles that underlie life is crucial in understanding its evolution. It gives concrete examples on how designs can be applied to evolution in the same way an engineer uses designs in creating building or bridges, or a software engineer that designs programs that can evolve. If we apply the notion of a design for evolution and realize that it is in its basis an evolving system of molecular machines, we can start to reverse engineer evolution and understand life. This article shows scenario’s for the origin of life and cel- lular life and how eukaryotic cells evolved to multicellular organisms. The driving force for evolution would be the intrinsic capability of the molecular machines to evolve and this basic tendency to evolve its ultimate goal. The scenarios that can be deduced following a design framework are drastically different from the theories that have been proposed so far. Based on the premise that that evolution can be modeled on a design framework, we can deduce that life evolved inside-out and that ontology reflects phylogeny on a molecular basis

Purpose – This paper aims to demonstrate the design and verification of a 3D reticulate octahedral cellular structure using both analytical modeling and additive manufacturing. Traditionally, it has been difficult to develop and verify designs for 3D cellular structures due to their design complexity. Design/methodology/approach – Unit cell modeling approach was used to model the octahedral cellular structure. By applying structural symmetry simplification, the cellular structure was simplified into a representative geometry that could be further designed with a standard beam theory. The verification samples were fabricated with EBM process using Ti6Al4V as materials, and compressive testing were performed to evaluate their properties. In addition, designs with different number of unit cells were investigated to evaluate their size effect. Findings – Explicit mechanical property design (including modulus and compressive strength) of the octahedral cellular structure was realized via parametric equations driven by geometrical designs and material types. In addition, it was verified both numerically and experimentally that the octahedral cellular structure exhibit unusual size effect, which is highly predictable. Unlike some of the other cellular structures, the octahedral cellular structure exhibits softening behavior when the number of unit cell increases between the sandwich skins, which could be explained by the upsetting effect commonly observed in bulk deformation processes. Originality/value – This paper established a more comprehensive understanding in the design of octahedral cellular structures, which could enable this type of structure to be designed for sandwich structures with higher fidelity. Therefore, this study not only demonstrated an efficient methodology to design 3D cellular structures using additive manufacturing, but also facilitated the development of design for an additive manufacturing theory.

This paper describes a method for layout design of a Cellular Manufacturing System (CMS) that would allow simultaneously, the grouping of machines unique to a part family into cells and those shared by several cells to be located together in functional sections. Using an illustrative example, this integration of the flexibility of a functional layout, the reduced handling gained from cell formation and allowance of limited intercell flows among adjacent cells is described. Thereby, the traditional strategy of simultaneous formation of part families and distribution of machines into independent cells which creates machine distribution and unbalanced utilization problems is avoided. This is justified by an analysis of the complex interactions between the critical subproblems in cell formation—machine grouping, part family formation, distribution and utilization of shared machines, intracell layout, intercell (or shop) layout and material handling. This approach represents a new direction in cell formation where, by allowing the handling function to limit the extent of machine duplication between adjacent cells, a new graph theoretic structure for simultaneous machine grouping and layout design was developed and validated.

The quest for sustainable poultry production using alternative feed ingredients is imperative. This study was conducted to assess the growth performance and blood profile of broiler chickens fed neem leaf meal (NLM) based diets with or without enzyme supplementation. Two hundred and eighty-eight, one-week old chicks (with an average weight of 98.44g) arranged in a completely randomized design with twelve birds/ replicate and three replicates/ treatment were fed NLM at 0, 1.5, 3 and 5% with or without Polyzme® to form eight experimental treatments. Data on initial body weights, weekly body weights and feed intake were taken during the trial which lasted for eight weeks and feed conversion ratio calculated. Blood was also collected for haematological studies at the 4 and 8 week by humanely severing the jugular vein. Results indicated that total weight gain at starter phase decreased progressively with increase in NLM inclusion and addition of Polyzme did not significantly (P>0.05) affect performance. At the finisher phase, growth performance was not significantly (P>0.05) influenced by NLM or enzyme addition. Furthermore, NLM with/without Polyzyme did not elicit any significant influence on the packed cell volume and haemoglobin concentration of the chickens. In conclusion, broiler chicks could tolerate up to 3% NLM and finishers up to 5% based on growth performance. The use of polyzyme at 400g/tonne in this study did not improve the utilization of NLM by the chickens. La recherche de la production de volaille durable utilisant des ingrédients d'alimentation alternatifs est impérative. Cette étude a été réalisée pour évaluer la performance de la croissance et le profil sanguin des régimes à base de feuilles neem (NLM) avec ou sans supplémentation en enzyme. Deux cent quatre-vingt-huit poussins âgés d'une semaine (avec un poids moyen de 98,44 g) disposés dans un design complètement randomisé avec douze oiseaux / répliqués et trois répliqués / traitement ont été nourris à 0, 1,5, 3 et 5% avec ou sans Polyzme pour former huit traitements expérimentaux. Les données sur les poids corporels initiaux, les poids corporels hebdomadaires et l'apport alimentaire ont été pris au cours de l'essai qui a duré huit semaines et le ratio de conversion alimentaire calculé. Le sang a également été collecté pour des études hématologiques à la 4ème et 8ème semaine en coupant humainement la veine jugulaire. Les résultats ont indiqué que le gain de poids total à la phase de démarrage a diminué progressivement avec l'augmentation de l'inclusion de NLM et l'addition de polyzme n'a pas significativement (p> 0,05) affecter les performances. À la phase de finition, la performance de la croissance n'était pas significativement (p> 0,05) influencée par l'addition NLM ou enzyme. De plus, la NLM avec / sans polyzyme n'a suscité aucune influence significative sur le volume de la cellule emballé et la concentration en hémoglobine des poulets. En conclusion, les poussins de chair pourraient tolérer jusqu'à 3% de NLM et des finisseurs jusqu'à 5% sur la base de la performance de la croissance. L'utilisation de polyzyme à 400 g / tonne dans cette étude n'a pas amélioré l'utilisation de NLM par les poulets.

Purpose The purpose of the paper is to propose a homogenization-based topology optimization method to optimize the design of variable-density cellular structure, in order to achieve lightweight design and overcome some of the manufacturability issues in additive manufacturing. Design/methodology/approach First, homogenization is performed to capture the effective mechanical properties of cellular structures through the scaling law as a function their relative density. Second, the scaling law is used directly in the topology optimization algorithm to compute the optimal density distribution for the part being optimized. Third, a new technique is presented to reconstruct the computer-aided design (CAD) model of the optimal variable-density cellular structure. The proposed method is validated by comparing the results obtained through homogenized model, full-scale simulation and experimentally testing the optimized parts after being additive manufactured. Findings The test examples demonstrate that the homogenization-based method is efficient, accurate and is able to produce manufacturable designs. Originality/value The optimized designs in our examples also show significant increase in stiffness and strength when compared to the original designs with identical overall weight.

The design of cellular materials has recently undergone a paradigm shift, enabled by developments in Additive Manufacturing and design software. No longer do cellular materials have to be limited to traditional shapes such as honeycomb panels or stochastic foams. With this increase in design freedom comes a significant increase in optionality, which can be overwhelming to the designer. This paper aims to provide a framework for thinking about the four key questions in cellular material design: how to select a unit cell, how to vary cell size spatially, what the optimal parameters are, and finally, how best to integrate a cellular material within the structure at large. These questions are posed with the intent of stimulating further research that can address them individually, as well as integrate them in a systematic methodology for cellular material design. Different state-of-the-art solution approaches are also presented in order to provoke further investigation by the reader.

Resumo:

Most research done on the design of cellular production systems also has examined one of the main areas of design including cell formation, cellular layout, and material handling. Some research studies also have been done by considering the lack of independence of these areas, two areas simultaneously, and three areas sequentially. The main goal of this research is to present a mathematical framework for designing and also providing the efficient methods for solving the desired problem.

Parity-preserving reversible circuits are gaining importance for the development of fault-tolerant systems in nanotechnology. On the other hand, Quantum-dot Cellular Automata (QCA), a potential alternative to CMOS, promises efficient digital design at nanoscale. This work targets design of reversible ALU (arithmetic logic unit) in QCA (Quantum-dot Cellular Automata) framework. The design is based on the fault tolerant reversible adders (FTRA) introduced in this paper. The proposed fault tolerant adder is a parity-preserving gate, and QCA implementation of FTRA achieved 47.38% fault-free output in the presence of all possible single missing/additional cell defects. The proposed designs are verified and evaluated over the existing ALU designs and found to be more efficient in terms of design complexity and quantum cost.

Quantum-dot cellular automata (QCA) is a highly attractive alternative to CMOS for future digital circuit design, relying on its high-performance and low-power-consumption features. This paper analyzes and compares previously published five-input majority gates. These designs do not perform well in terms of physical properties, especially concerting power consumption. Therefore, an ultra-low-power five-input majority gate in one layer is proposed, which uses a minimum number of cells and smaller area, and achieves the expected highly polarized output compared with previous designs. In order to evaluate its practicability, a new one-bit coplanar full-adder is proposed. The analysis results show that this full-adder performs well compared with existing multilayer and single-layer designs. The number of cells of the proposed design is reduced by 7.14% to get the same area and clock delay compared with the best coplanar full-adder. In addition, its power dissipation is also reduced by 9.28% at 0.5[Formula: see text], 11.09% at 1[Formula: see text] and 12.66% at 1.5[Formula: see text] in terms of average energy dissipation compared with the best single-layer design. QCADesigner tool is used to verify the simulation results of the proposed designs and QCAPro tool is used to evaluate the power dissipation of all considered designs.

Further downscaling of CMOS technology becomes challenging as it faces limitation of feature size reduction. Quantum-dot cellular automata (QCA), a potential alternative to CMOS, promises efficient digital design at nanoscale. Investigations on the reduction of QCA primitives (majority gates and inverters) for various adders are limited, and very few designs exist for reference. As a result, design of adders under QCA framework is gaining its importance in recent research. This work targets developing multi-layered full adder architecture in QCA framework based on five-input majority gate proposed here. A minimum clock zone (2 clock) with high compaction (0.01 μm2) for a full adder around QCA is achieved. Further, the usefulness of such design is established with the synthesis of high-level logic. Experimental results illustrate the significant improvements in design level in terms of circuit area, cell count, and clock compared to that of conventional design approaches.

This paper presents a virtual cellular manufacturing system building model based on axiomatic design theory. By now most discussions of virtual manufacturing cellular focus on how to format a virtual cell and how to optimize a virtual cell in the execution layer. The attention to “system cost” and “efficiency” mostly were given only after the system-generated. In this paper we build a complete virtual cellular manufacturing system, and pay attention to “system cost” and “efficiency” in the conceptual design phase to make sure the techniques and resource which we choose is low-cost and non-redundant. Meanwhile in Process Domain of the model, we blend the logistics balance idea of TOC theory, waste elimination philosophy of lean manufacturing and the existing conclusions of the virtual cell literature to make sure the tools which we choose are more effective. The model will clearly set out the concept, principle and technology hierarchy of virtual cellular manufacturing system, and can be an effective map for manufacturing enterprises with low-volume and high-variety to apply the virtual cellular production.

Purpose – The aim of this study is to perform a comparative study on sandwich structures with several types of three-dimensional (3D) reticulate cellular structural core designs for their low-energy impact absorption abilities using powder bed additive manufacturing methods. 3D reticulate cellular structures possess promising potentials in various applications with sandwich structure designs. One of the properties critical to the sandwich structures in applications, such as aerospace and automobile components, is the low-energy impact performance. Design/methodology/approach – Sandwich samples of various designs, including re-entrant auxetic, rhombic, hexagonal and octahedral, were designed and fabricated via selective laser sintering (SLS) process using nylon 12 as material. Low-energy drop weight test was performed to evaluate the energy absorption of various designs. Tensile coupons were also produced using the same process to provide baseline material properties. The manufacturing issues such as geometrical accuracy and anisotropy effect as well as their effects on the performance of the structures were discussed. Findings – In general, 3D reticulate cellular structures made by SLS process exhibit significantly different characteristics under low-energy drop weight impact compared to the regular extruded honeycomb sandwich panels. A hexagonal sandwich panel exhibits the largest compliance with the smallest energy absorption ability, and an octahedral sandwich panel exhibits high stiffness as well as good impact protection ability. Through a proper geometrical design, the re-entrant auxetic sandwich panels could achieve a combination of high energy absorption and low response force, making it especially attractive for low-impact protection applications. Originality/value – There has been little work on the comparative study of the energy absorption of various 3D reticulate cellular structures to date. This work demonstrates the potential of 3D reticulate cellular structures as sandwich cores for different purposes. This work also demonstrates the possibility of controlling the performance of this type of sandwich structures via geometrical and process design of the cellular cores with powder bed additive manufacturing systems.

Cell formation（CF）and cellular layout design are the two main steps in designing a cellular manufacturing system (CMS). Efficient grouping is the prerequisite of a successful Cellular Manufacturing, and it is too hard to obtain a perfect consequence of CF and layout simultaneously. In this paper, a two-stage strategy is used to solve CF problem and layout sequentially. At the first stage, the cells are formed based on the part-machine clustering results obtained through the genetic algorithm, to get the initial inter-cell layout. At the second stage, the genetic algorithm is used to improve the solution obtained, to minimize the handling cost and maximize the utility of the machines.
