Abstract: Aspects described herein allow multiple devices to function as a coherent whole, allowing each device to take on distinct functions that are complementary to one another. Aspects described herein also allow the devices function as a coherent whole when interconnected devices and their respective applications are configured to operate in various operation modes, when management policies are employed to control the operation of the interconnected devices and their respective applications, when transferring content between the interconnected devices and storing the content at those devices, when obtaining access credentials for the interconnected devices that enable the devices to access enterprise resources, when a policy agent applies management policies to control operation of and interaction between the interconnected devices, and when the interconnected devices are used to access an enterprise application store.

Abstract: The concept of a “service template” is used to specify the “topology” (or structure) and “orchestration” (or invocation of management behavior) of IT services. Typically, services are provisioned in an IT infrastructure and their management behavior must be orchestrated in accordance with constraints or policies from there on, for example in order to achieve service level objectives. This specification introduces the formal description of Service Templates, including their structure, properties, and behavior.

Abstract: Orchestration is an approach to Technology Enhanced Learning that emphasizes attention to the challenges of classroom use of technology, with a particular focus on supporting teachers' roles. The present collection of papers on orchestration highlights broad agreement that classrooms are variable and complex and that teachers have an important role in adapting materials for use in their own classrooms. The synthesis also shows a difference of opinions in how useful ''orchestration'' is as a metaphor, the proper scope of issues to include when studying orchestration, and how to approach design. Despite the lack of consensus, orchestration is a timely and important shift of focus and all of the approaches merit further exploration. The field shows healthy self-criticism and debate, which is the hallmark of fields with the potential for great progress.

Abstract: The present invention relates to field of application and more specifically to analysis of applications for determining security and quality issues. The present invention describes an application analysis system providing a platform for analyzing applications which is useful in finding security and quality issues in an application. In particular, the present invention is composed of an advanced fusion analyzer which gains an understanding of the application behavior by using a multi-way coordination and orchestration across components used in the present invention to build an continuously refine a model representing knowledge and behavior of the application as a large network of objects across different dimensions and using reasoning and learning logic on this model along with information and events received from the components to both refine and model further as well as drive the components further by sending information and events to them and again using the information and events received as a result to further trigger the entire process until the system stabilizes. The present invention is useful in analysis of internet/intranet based web applications, desktop applications, mobile applications and also embedded systems as well as for hardware, equipment and machines controlled by software.

Abstract: The case(s) demonstrates the importance of business process management (BPM) and business intelligence systems (BIS) in achieving better firm performance. It has been well documented in the literature that research on the effectively usage and combination of knowledge from BPM and BIS in turbulent service environments is limited. In response, we conduct an exploratory comparative case study of four firms in banking and telecommunication industries that have implemented BPM initiative and BIS solution. Our results firstly highlight that actual results of applying BPM and BIS differ greatly from the results that were originally planned. Secondly, we find that BIS initiatives are usually driven by improving marketing and sales, while BPM initiatives are driven by improving business processes. Thirdly, we identify that there is a lack of strong commitment to using both systems for supporting performance management.

Abstract: This article addresses the potential impact of emerging technologies and solutions, such as software defined networking and network function virtualization, on carriers' network evolution. It is argued that standard hardware advances and these emerging paradigms can bring the most impactful disruption at the network's edge, enabling the deployment of clouds of nodes using standard hardware: it will be possible to virtualize network and service functions, which are provided today by expensive middleboxes, and move them to the edge, as close as possible to users. Specifically, this article identifies some of key technical challenges behind this vision, such as dynamic allocation, migration, and orchestration of ensembles of virtual machines across wide areas of interconnected edge networks. This evolution of the network will profoundly affect the value chain: it will create new roles and business opportunities, reshaping the entire ICT world.

Abstract: Digital resources offer opportunities to improve mathematics teaching and learning, but meanwhile may question teachers’ practices. This process of changing teaching practices is challenging for teachers who are not familiar with digital resources. The issue, therefore, is what teaching practices such so-called ‘mid-adopting’ mathematics teachers develop in their teaching with digital resources, and what skills and knowledge they need for this. To address this question, a theoretical framework including notions of instrumental orchestration and the TPACK model for teachers’ technological pedagogical content knowledge underpins the setting-up of a project with twelve mathematics teachers, novice in the field of integrating technology in teaching. Technology-rich teaching resources are provided, as well as support through face-to-face group meetings and virtual communication. Data include lesson observations and questionnaires. The results include a taxonomy of orchestrations, an inventory of skills and knowledge needed, and an overview of the relationships between them. During the project, teachers do change their orchestrations and acquire skills. On a theoretical level, the articulation of the instrumental orchestration model and the TPACK model seems promising.

Abstract: In this paper we give a preview of our system for automatically evaluating attention in the classroom. We demonstrate our current behaviour metrics and preliminary observations on how they reflect the reactions of people to the given lecture. We also introduce foundations of our hypothesis on peripheral awareness of students during lectures.

Abstract: This paper presents our research of a pedagogical model known as Knowledge Community and Inquiry (KCI), focusing on our design of a technological infrastructure for the orchestration of the complex CSCL scripts that characterize KCI curricula. We first introduce the KCI model including some basic design principles, and describe its dependency on real time learning analytics. Next, we describe our technology, known as SAIL Smart Space (S3), which provides scaffolding and analytic support of sequenced interactions amongst people, materials, tools and environments. We outline the critical role of the teacher in our designs and describe how S3 supports their active role in orchestration. Finally we outline two implementations of KCI/S3 and the role of learning analytics, in supporting dynamic collective visualizations, real time orchestrational logic, and ambient displays.

Abstract: 'Simulating the Inter-Cloud' (SimIC) is a discrete event simulation toolkit based on the process oriented simulation package of SimJava. The SimIC aims of replicating an inter-cloud facility wherein multiple clouds collaborate with each other for distributing service requests with regards to the desired simulation setup. The package encompasses the fundamental entities of the inter-cloud meta-scheduling algorithm such as users, meta-brokers, local-brokers, datacenters, hosts, hyper visors and virtual machines (VMs). Additionally, resource discovery and scheduling policies together with VMs allocation, re-scheduling and VM migration strategies are included as well. Using the SimIC a modeler can design a fully dynamic inter-cloud setting wherein collaboration is founded on meta-scheduling inspired characteristics of distributed resource managers that exchange user requirements as driven events in real-time simulations. The SimIC aims of achieving interoperability, flexibility and service elasticity while at the same time introducing the notion of heterogeneity of multiple clouds' configurations. In addition it accepts an optimization of a variety of selected performance criteria for a diversity of entities. The crucial factor of dynamics consideration has implemented by allowing reactive orchestration based on current workload of already executed heterogeneous user specifications. These are in the form of text files that the modeler can load in the toolkit and occurs in real-time at different simulation intervals. Finally, a unique request is scheduled for execution to an internal cloud datacenter host VM that is capable of performing the service contract. This is formally designed in Service Level Agreements (SLAs) based upon user profiling.

Abstract: The paradigm of Cloud computing introduces new approaches to manage IT services going beyond concepts originating in traditional IT service management. The main goal is to automate the whole management of services to reduce costs and to make management tasks less error-prone. Two different service management paradigms are used in practice: configuration management and model-driven Cloud management. The latter one aims to be a holistic management approach for services in the Cloud. However, both management paradigms are originating in different backgrounds, thus model-driven Cloud management does not cover all aspects of configuration management that are key for Cloud services. This paper presents approaches for integrating configuration management with model-driven Cloud management and how they can be realized based on the OASIS Topology and Orchestration Specification for Cloud Applications and Chef, a popular configuration management tool. These approaches enable the creation of holistic and highly portable service models.

Abstract: In this paper we focus on mobile crowdsensing applications for community sensing where sensors and mobile devices jointly collect and share data of interest to observe and measure phenomena over a larger geographic area. Such applications, e.g., environmental monitoring or crowdsourced traffic monitoring, involve numerous individuals that on the one hand continuously contribute sensed data to application servers, and on the other hand consume the information of interest to observe a phenomenon typically in their close vicinity. Energy-efficient and context-aware orchestration of the sensing process with data transmission from sensors through mobile devices into the cloud, as well as from the cloud to mobile devices such that information of interest is served to users in real-time, is essential for such applications, primarily due to battery limitations of both mobile devices and wearable sensors. In addition, the latency of data propagation represents their key quality measure from the user's perspective. Publish/subscribe middleware offers the mechanisms to deal with those challenges: It enables selective real-time acquisition and filtering of sensor data on mobile devices, efficient continuous processing of large data volumes within the cloud, and near real-time delivery of notifications to mobile devices. This paper presents our implementation of a publish/subscribe middleware system which is tailored to the requirements of mobile and resource-constrained environments with a goal to reduce the overall energy consumption in such environments, and proposes a general architecture for mobile crowdsensing applications. We demonstrate the usability of both the architecture and middleware through our application for air quality monitoring, and discuss the energy footprint of the proposed solution.

Abstract: Organizations today are required to adhere to a number of compliance concerns from laws, regulations and policies. Compliance is achieved through defining and implementing so-called controls in the organizations' business processes. Organizations that build their systems based on the process-driven SOA paradigm realize business processes through orchestration of services to handle the process' business activities. These business activities or groups of business activities in some cases realize the compliance controls. We propose an approach for implementing event-based compliance monitoring infrastructure that observes such business processes to verify that compliance is indeed adhered to. Our approach is essentially a model-driven technique for realizing this infrastructure. We implement a domain-specific language for specification of compliance directives, and we include code generation templates to generate compliance monitoring code, which is leveraged by complex event processing components to monitor for compliance. We evaluate the impact of our approach on the effort and productivity of a developer who is specifying compliance directives.

Abstract: The Graphics Processing Unit (GPU) is gaining popularity as a co-processor to the Central Processing Unit (CPU). However, harnessing its capabilities is a non-trivial exercise that requires good knowledge of parallel programming, more so when the complexity of these applications is increasingly rising. Languages such as StreamIt [1] and Lime [2] have addressed the offloading of composed computations to GPUs. However, to the best of our knowledge, no support exists at library level. To this extent, we propose Marrow, an algorithmic skeleton framework for the orchestration of OpenCL computations. Marrow expands the set of skeletons currently available for GPU computing, and enables their combination, through nesting, into complex structures. Moreover, it introduces optimizations that overlap communication and computation, thus conjoining programming simplicity with performance gains in many application scenarios. We evaluated the framework from a performance perspective, comparing it against hand-tuned OpenCL programs. The results are favourable, indicating that Marrow's skeletons are both flexible and efficient in the context of GPU computing.

Abstract: This paper presents the results and experiences of a six-week deployment of multiple digital tabletops in a school. Dillenbourg's orchestration framework was used both to guide the design and analysis of the study. Four themes, which directly relate to the design of the technology for the classroom, out of the 15 orchestration factors are considered. For each theme, we present our design choices, the relevant observations, feedback from teachers and students, and we conclude with a number of lessons learned in the form of design recommendations. The distinguishing factors of our study are its scale (in terms of duration, number of classes, subjects, and teachers), and its 'in-the-wild' character, with the entire study being conducted in a school, led by the teachers, and using teacher-prepared, curriculum-based tasks. Our primary contributions are the analysis of our observations and design recommendations for future multi-tabletop applications designed for and deployed within the classroom. Our analyses and recommendations meaningfully extend HCI's current design understandings of such settings.

Abstract: This response to Dillenbourg's postulations on Orchestration analyses the relationship between classroom logistics and learning. It is necessary to detail the precise actions that the teacher must perform in order to apply the proposed strategies for the integration of digital and non-digital resources. It is not about teacher training; it is about giving teachers the tools to structure their classes and empower them beyond the training process. Every aspect of the class should be specified, leaving what finally will be performed to the teacher. We conclude that an adequate orchestration helps to guide the teacher through the work to be performed in the classroom, allowing a shift from an instructor-centered arrangement, in which the teacher radiates knowledge before a passive class of students, to one where the students actively participate, with the teacher acting as a mediator.

Abstract: This paper revisits the analysis of how the interactive whiteboard (IWB) can contribute to effective pedagogy. It builds on previous work concerning the relationship between the features of IWBs and associated technologies and some key components of pedagogy, including the stage of IWB use, the role of ICT, the type of interactivity, and the overarching aspect of orchestration for learning. Two example lessons are constructed to illustrate the relationships associated with a basic stage of IWB use as a blackboard substitute and the most sophisticated, synergistic stage of IWB use. The analysis of these lessons is used to show that in the synergistic lesson, the IWB functions as a hub for classroom activity. The key difference is that both the teacher and pupils use the affordances of IWB for orchestration of activity rather than merely using a set of unrelated tools predominantly used by the teacher. Implications are drawn concerning the need to develop skills in orchestration for learning alongside technical skills in IWB use through initial teacher education and subsequent professional learning.

Abstract: This paper presents the first relevant results of the project BRISEIDE ‐ BRIdging SErvices, 7 Information and Data for Europe. BRISEIDE aims at providing operators with a time-aware 8 extension of data models and value added services for spatio-temporal data management, 9 authoring, processing, analysis and interactive visualization in several emergency-related 10 scenarios including, most notably, landslides. Within this context a number of WPSs devoted 11 to spatial analysis have been developed and integrated within existing open source 12 frameworks. Spatio-temporal processing services are exposed via the web and are made 13 available through compatible WebGIS applications. Through BRISEIDE, operators can 14 access processing services through an interactive web-based 3D GeoBrowser capable to 15 allow management, authoring, interaction, filtering of existing data. The 3D GeoBrowser 16 allows interactive orchestration of spatio-temporal WPSs providing support to chaining of 17 required processing units. This ensures interactive access to datasets and asynchronous 18 processing at the server side. The project mobilizes a value-chain of stakeholders to validate 19 the pilots from a technical, organizational and legal standpoint.

Abstract: A system and method for providing a service management engine for use with a cloud computing environment. In accordance with an embodiment, enterprise software applications (e.g., Fusion Middleware applications) can be instantiated as services within a cloud platform, where they are then made accessible by other (e.g., customer) applications. In an embodiment, a service management engine (SME), in communication with an orchestration engine, can be used to provision services as one or more different service types, according to a service definition package (SDP). Service types can be instantiated according to the configuration of the cloud platform itself, and the contents of the SDP, including discovering, provisioning, and associating service types with system resources, to address different customer requirements.
