This paper explores the genre of flexible architecture - buildings that are intended to respond to changing situations in their use, operation, or location. This is architecture that adapts rather than stagnates; responds to change rather than rejects it; is motive rather than static. It is a design form that is by its essence cross-disciplinary and multi-functional and consequently, is frequently innovative and expressive of contemporary design issues. By revealing its basis and the factors that are determining its development, the value and relevancy of flexible architecture to contemporary problems associated with technological, social and economic change can be revealed.

The characteristics of flexible architecture are explored by examining the design decisions that lead to culturally responsive buildings. It examines the underlying factors that generate a sense of place and why traditional and historic building patterns have been successful in creating genuinely adaptable architecture. It relates the characteristics of flexible architecture to Open Building principles and examines the effect that such design can have within the different levels in the built environment. The paper focuses special attention on contemporary architecture by examining the recent work of the Japanese architect Toyo Ito, in particular his recently completed Matsumoto Performing Arts Centre, Nagano Prefecture, Japan. Based on conversation with the designer and first-hand study of the building, the specific factors that make this new design a valuable resource in the search for flexible architecture strategies are explored.

This paper expands on the author's previous research into the foundation areas of this topic, in particular the genre of portable architecture, the impact of technology on the development of architectural form, and the development of experimental and innovative house design in the twentieth century. Its subject is expanded in his forthcoming book Flexible: Architecture That Responds to Change to be published by Laurence King, London, in 2006.

The aim in this paper is to describe and explain the flexibility offered by different business models adopted by different firms as they strive to achieve higher levels of business performance.

Cross‐sectional research is used to investigate a matched pair sample of 20 high‐performing and 20 low‐performing firms in the UK. The relationship between business model architectures and focus are examined and their implications for flexibility are illustrated and discussed.

The flexibility offered by different business models is explored through the way organisations select and integrate three inter‐related elements to devise flexible business models, i.e. network influence, transactional relationships, and corporate ownership. Affected by situated practices in each business network and the market position or business size, companies select and integrate various configurations of these elements to respond to the constantly evolving demands of end‐customers.

Although based upon a cross‐sectional analysis of a matched pair sample, the concept of “flexible business models” has far wider managerial implications. The efficiency of the proposed approach is achieved through the reduction into three inter‐related elements that allow flexible configuration and re‐adjustment.

Companies can use the flexible business model approach to examine their own selection and integration of network influence, transactional relationships and corporate ownership and scrutinise their flexibility and performance in the marketplace.

The contribution of this paper is the development of the flexible business models concept, based on an empirical investigation of firms in the UK.

The fabulous results of convolution neural networks in image-related tasks attracted attention of text mining, sentiment analysis and other text analysis researchers. It is, however, difficult to find enough data for feeding such networks, optimize their parameters, and make the right design choices when constructing network architectures. The purpose of this paper is to present the creation steps of two big data sets of song emotions. The authors also explore usage of convolution and max-pooling neural layers on song lyrics, product and movie review text data sets. Three variants of a simple and flexible neural network architecture are also compared.

The intention was to spot any important patterns that can serve as guidelines for parameter optimization of similar models. The authors also wanted to identify architecture design choices which lead to high performing sentiment analysis models. To this end, the authors conducted a series of experiments with neural architectures of various configurations.

The results indicate that parallel convolutions of filter lengths up to 3 are usually enough for capturing relevant text features. Also, max-pooling region size should be adapted to the length of text documents for producing the best feature maps.

Top results the authors got are obtained with feature maps of lengths 6–18. An improvement on future neural network models for sentiment analysis could be generating sentiment polarity prediction of documents using aggregation of predictions on smaller excerpt of the entire text.

The purpose of this paper is to propose an effective and economical management platform to realize real-time tracking and tracing for prepackaged food supply chain based on Internet of Things (IoT) technologies, and finally ensure a benign and safe food consumption environment.

Following service-oriented architecture, a flexible layered architecture of tracking and tracing platform for prepackaged food is developed. Besides, to reduce the implementation cost while realizing fine-grained tracking and tracing, an integrated solution of using both the QR code and radio-frequency identification (RFID) tag is proposed. Furthermore, Extensible Markup Language (XML) is adopted to facilitate the information sharing among applications and stakeholders.

The validity of the platform has been evaluated through a case study. First, the proposed platform is proved highly effective on realizing prepackaged food tracking and tracing throughout its supply chain, and can benefit all the stakeholders involved. Second, the integration of the QR code and RFID technologies is proved to be economical and could well ensure the real-time data collection. Third, the XML-based method is efficient to realize information sharing during the whole process.

The contributions of this paper lie in three aspects. First, the technical architecture of IoT-based tracking and tracing platform is developed. It could realize fine-grained tracking and tracing and could be flexible to adapt in many other areas. Second, the solution of integrating the QR code and RFID technologies is proposed, which could greatly decrease the cost of adopting the platform. Third, this platform enables the information sharing among all the involved stakeholders, which will further facilitate their cooperation on guaranteeing the quality and safety of prepackaged food.

The purpose of this paper is to investigate the principles supporting organizational change management.

The paper develops a qualitative study from a single case which focuses on how the military (NATO) transformed their functionally integrated organizational form to gain additional flexibility and responsiveness.

The findings indicate that the transformation of military organizations has led to reshaping and aligning communication artifacts and organizational structures. In addition, it also entailed significant adaptations of the way knowledge is divided, allocated and coordinated among units, with a particular emphasis on standardization processes.

The implications of this study for scholars and practitioners are twofold. First, it shows that the conditions for success in organizational transformation reside in the consistency of the design strategy adopted by the organization. In particular, the findings provide evidence that the alignment of the structural and cognitive designs is critical but hard to achieve. Second, organizations and managers should devote time and effort to support the codification and standardization of both component and architectural knowledge. This contribution is limited by looking at a single case. On the premise that model generalization depends upon extensive empirical data, the current paper should be considered as a preliminary/exploratory research that aims at identifying the principles supporting organizational change management.

The originality of this paper is to look at military organizations to elaborate on a theoretical model of organization design which links together the structural and cognitive views and discuss its main implications for organizational change management.

The increasing speed and volume of attacks against networked systems highlights the need to automate the intrusion response process. This paper proposes a means by which such automation may be achieved, and presents details of a practical implementation.

The paper outlines the architecture of a flexible and intelligent automated response system that is able to adapt response decisions according to the context in which a detected incident has occurred. The discussion presents details of a prototype implementation that has been used to evaluate the concept in practice, and demonstrates the feasibility of assessing contextual factors associated with detected incidents.

A series of worked examples are presented to show how the same incident occurring in different contexts will trigger different decisions from the response system.

The paper contributes towards the domain of intrusion response, and proposes an approach that would enable automation of the response process to be more acceptable to security administrators.

Streamlining automated processes is currently undertaken by developing optimization methods and algorithms for robotic manipulators. This paper aims to present a new approach to improve streamlining of automatic processes. This new approach allows for multiple robotic manipulators commonly found in the industrial environment to handle different scenarios, thus providing a high-flexibility solution to automated processes.

The developed system is based on a spatial discretization methodology capable of describing the surrounding environment of the robot, followed by a novel path-planning algorithm. Gazebo was the simulation engine chosen, and the robotic manipulator used was the Universal Robot 5 (UR5). The proposed system was tested using the premises of two robotic challenges: EuRoC and Amazon Picking Challenge.

The developed system was able to identify and describe the influence of each joint in the Cartesian space, and it was possible to control multiple robotic manipulators safely regardless of any obstacles in a given scene.

This new system was tested in both real and simulated environments, and data collected showed that this new system performed well in real-life scenarios, such as EuRoC and Amazon Picking Challenge.

The new proposed approach can be valuable in the robotics field with applications in various industrial scenarios, as it provides a flexible solution for multiple robotic manipulator path and motion planning.

The aim of this paper is to investigate the importance of information management in modular product architecture for customized product development.

The objective of this research is to analyze product architecture in terms of information exchange and show its influence in product customization. A case study is presented with a view to modelling the information tracking necessary for product architecture and customization.

In today's volatile business environment, appropriate ways of information management could be an added value for manufacturing firms. This paper deals with the importance of information flow in product architecture. The role of information exchange influences the basic architecture of the product development process, which also affects the general theme of product customization.

The importance of information flow highlights the design architecture and brings flexibilities to the product development process. This concept is illustrated through a single case example, which may not be translated as a generic output. Multiple case study approaches could be undertaken in future research to rigorously analyze the influence of information exchange on product architecture.

In order to comply with growing customization, firms are looking for flexible design architecture in their product development process. The presented approach will be beneficial for designers and organizational managers in developing flexible customized product or services.

This paper implements a unique approach to modular product architecture through information dependencies among components and sub‐assemblies. The basic principle of modular product architecture and how it affects product customization are also reported.

Internet has changed radically in the way people interact in the virtual world, in their careers or social relationships. IoT technology has added a new vision to this process by enabling connections between smart objects and humans, and also between smart objects themselves, which leads to anything, anytime, anywhere, and any media communications. IoT allows objects to physically see, hear, think, and perform tasks by making them talk to each other, share information and coordinate decisions. To enable the vision of IoT, it utilizes technologies such as ubiquitous computing, context awareness, RFID, WSN, embedded devices, CPS, communication technologies, and internet protocols. IoT is considered to be the future internet, which is significantly different from the Internet we use today. The purpose of this paper is to provide up-to-date literature on trends of IoT research which is driven by the need for convergence of several interdisciplinary technologies and new applications.

A comprehensive IoT literature review has been performed in this paper as a survey. The survey starts by providing an overview of IoT concepts, visions and evolutions. IoT architectures are also explored. Then, the most important components of IoT are discussed including a thorough discussion of IoT operating systems such as Tiny OS, Contiki OS, FreeRTOS, and RIOT. A review of IoT applications is also presented in this paper and finally, IoT challenges that can be recently encountered by researchers are introduced.

Studies of IoT literature and projects show the disproportionate importance of technology in IoT projects, which are often driven by technological interventions rather than innovation in the business model. There are a number of serious concerns about the dangers of IoT growth, particularly in the areas of privacy and security; hence, industry and government began addressing these concerns. At the end, what makes IoT exciting is that we do not yet know the exact use cases which would have the ability to significantly influence our lives.

This survey provides a comprehensive literature review on IoT techniques, operating systems and trends.
