A THEORY OF INTERACTIONAL SYSTEMS: SEMANTIC CONNECTIONS AND RELATIONAL CONTEXTICS
by Albin Wagener
Abstract: The aim of this paper is to develop a theoretical proposition based on the study of intercultural miscommunication, which has shown that the creation, evolution and ending of interactional misunderstandings can be understood by using systemic theories (Wagener, 2009a; Wagener, 2010). In this perspective, human interactions obey basic principle that can be applied to biological life in its simplest expression, although said interactions draw on sophisticated devices used to trigger and maintain relationships and communication variations. We thus wish to combine the systemic, the pragmatic and the connectionist paradigms to represent both nuances and subtleties of human rapports. A systemic model of human interactions, namely the interactional system, would then draw on the flexibility and adaptability of its fundamental parameters. The main purpose of the present work is to elaborate on a theory of interactional systems by proposing a coherent and comprehensive approach of interactional dynamics, in order to present an accurate modelization of the complexity of human interactions especially when said interactions suffer situations of conflictual destabilization.

The Need for systemic snalysis and designmethodology of the medical equipments
by Mohamed Najeh LAKHOUA
Abstract: The diversity of the medical equipments in hospital systems requires a structured analysis and design methodology in order to get perceptions and correct understandings of the internal working of these equipments. Indeed, medical equipments are intended to help the diagnosis and the medical problem treatment. They are conceived in general according to rigorous rules of security. Then, we identify various the basis types of the medical equipments: diagnosis; therapeutic; vital; monitors and laboratory equipments. To answer to this problem, the proposed methodology is based on the use of a systemic modeling approach in order to analysis and design medical equipments. This is why it is necessary to identify the rigorous security rules of various medical equipments as well as all the technical aspects related to the conception and the development of systems based on electronics and data processing.
Keywords: analysis and modeling; medical equipment; system modeling; hospital system.
Viable System Dynamics Intelligent Framework for Assessing and Optimizing Systemic Reengineering for e-Governance environments: A Case Study in Corfu Sunspots Tourist Agency
by Nikitas Assimakopoulos, Alexandros Miaris, Anastassios Riggas
Abstract: Dealing with problems in complex environments that impede organizational cohesion, information dissemination and coordination is extremely difficult nowadays. Usage of technology without sophisticated information sharing planning and solid processes that serve with a bottom-up approach the needs of each individual within an organization, undermines time, cost and quality of deliverables. The eG4M (e-Government for Mediterranean Countries)  project basically concentrates on extending, completing and improving the e-Model through the achievement of new research results and its application by participating with the support of the Mediterranean Countries (MCs) – in establishing and consolidating their e-Government systems. This paper focuses on the development of a generic system dynamics model that illustrates the behavior of e-governance systems based on the VSM (Viable Systems Model) as well as the development of a web, collaborative intelligent framework that is built upon the system dynamics model. The framework is meant to have the form of a web-based simulation that is able to identify critical issues related to product, customer, information sharing and service quality using visualizations, automated analytics and impact analysis delivered with natural language format to support the systemic reengineering process, mitigate risk, predict issues during the planning phase and help the user understand complexity and inform his decisions with predictive insights. Modeling the behavior of an e-governance system and being able to automatically process complex relationships, data and issues upon this system mitigates uncertainty at all levels, increases awareness and understanding of the real world and delivers sustainability and viability, increases growth and sets the basis for process autonomy and better coordination, controls and quality of deliverables.

Performance Evaluation of Robust Attitude Control System using Control Moment Gyros for Rapid Multi-Target Observation
by Ting Hao, Saburo Matunaga
Abstract: Since observation tasks of Micro-satellite require rapid multi-target acquisition and high pointing accuracy, the single-gimbal control moment gyro (CMG) is considered as an ideal torque-generating actuator due to its practical performance for the satellite. A pyramid structure with four CMGs is considered for the attitude control system (ACS). This paper compares two useful robust attitude control algorithms (sliding mode control method and high order sliding mode control method). These control methods have improved the system's robustness and accuracy. Moreover, the control algorithms are also derived to compensate the internal disturbance that is produced from the guidance trajectory law. Furthermore, higher order sliding mode control method can remove the chattering effect if an appropriate relative degree was chosen. Although CMG can produce larger torque compared with reaction wheels or magnetic torques but the singularity problem inherent CMGs is inevitable during the design period. This challenge makes attitude control system become one of the key technologies. The pseudo-inverse steering logic based on mixed two-norm and least-squares minimization is chosen in this paper which can deal with both the internal singularity problem and momentum saturation singularities. This paper describes architecture of the ACS, its components, algorithms and verification methods. This attitude control system is verified through numerical simulation. The results demonstrate the validity and feasibility of the proposed approach.

Viability and Change in the Twenty-First Century Organization: A Cybernetic Perspective
by Dimitrios Varsos
Abstract: The twenty-first century organization works and networks in an interconnected world where ambiguity and uncertainty abound. This dynamic environment necessitates continuous vigilance over the forces that impact the organizations performance, and continual refinement of the sociotechnical infrastructure that supports its purpose. Relevant, accurate, and timely information is essential to decisions associated with managing change. However, without resilient structural arrangements that are able to effectively cope with change, the outcomes of decisions taken will be speculative, at best. In this article, we explore the (core) functions that have formed the traditional paradigm of management, and consider the cybernetic structure of the Viable System Model as an alternate means of maintaining organizational cohesion during times of relative normality and during times of change. Moreover, we describe a pragmatic conceptual framework that bridges the gap between the traditional and the cybernetic approach that can be used to manage change. Finally, we apply this framework to transform a traditional performance monitoring scheme into an integrated multidimensional performance measurement system.

A systems perspective on school improvement approaches
by Lieschen Venter, Maria M. Vosloo
Abstract: In this paper the impact of school leadership on the learners' academic performance is considered in the South African context. School leadership is a systemic concept that cannot be analysed out of its context and we develop a simulation model to understand the effect of various school leadership and management intervention programmes on the principals themselves, and on the schools which they lead. The model is initiated with a mix of narrative and qualitative data. Interventions form the basis of what-if scenarios and model results are used to illustrate the systemic nature of the education environment. We show that interventions have to be made early and consistently to improve and maintain the system and that there is no immediate silver bullet solution. Model results allow school leaders to visualize the non-linearity, time dependence and interdependence of the impact of their decisions.
Keywords: South Africa; basic education; systems simulation; interventions; scenario testing.
Lower and Upper Bound of the Laplacian Energy with Real and Complex Roots of an Intuitionistic Fuzzy Directed Graph
by B. PRABA, G. DEEPA, V.M. CHANDRASEKARAN
Abstract: In this paper, the concept of Laplacian energy of a fuzzy graph is extended to the Laplacian energy of an intuitionistic fuzzy directed graph. The degree matrix and the Laplacian energy of an intuitionistic fuzzy directed graph are defined. The upper and lower bound are derived for the Laplacian energy of an intuitionistic fuzzy directed graph. Existing work has been conjectured that the inequality holds for all graphs. But we are conjectured that the inequality does not hold for an intuitionistic fuzzy directed graph. Finally, numerical examples are illustrated for the defined work. Moreover, we analyzed the results for the energy of an intuitionistic fuzzy directed graph and Laplacian energy of an intuitionistic fuzzy directed graph.
Keywords: Energy of a graph; Energy of a fuzzy graph; Energy of an intuitionistic fuzzy graph; Laplacian energy of a graph; Laplacian energy of a fuzzy graph.
The inventory-routing problem in field supply logistics
by Yi Shu Ping, Li Yu Lin
Abstract: This paper considers the application units (AUs) operating within cropping fields as the "customers", and the farm depots as the "suppliers", while taking the fuel consumption rare (FCR) as a cost factor and adding it to the IRP. Then a dedicated classification of field supply logistics is devised based on a modified classification scheme and tailored to a conceptual application of the IRP. The research results show that delivery scheduling and planning problems in field supply logistics can be cast as IRP instances and solved by their corresponding methods. Overall, the adoption and modification of the IRP methodology provide a promising approach for the process improvement of field supply logistics.

A Novel Method Combining Fuzzy SVM and Sampling for Imbalanced Classification
by Tao Ma, Ying Hou, Jian-Jun Cheng, Xiao-Yun Chen
Abstract: The class imbalance problem has been reported to reduce performance of many existing learning algorithms in intrusion detection. However, the detection rates for minority classes still need to be improved. Thus, the novel hybrid method FSVMs is proposed to solve the problem in the paper, which integrates the prevailing sampling method SMOTE with Fuzzy semi-supervised SVM learning approach to class imbalanced intrusion detection data. The basic KDD Cup 1999 dataset, NSLKDD dataset and imbalanced dataset from UCI are used to evaluate the performance of proposed model. Experiment results show that the proposed method outperforms other state-of-the-art classifiers including Support Vector Machine (SVM), Back Propagation Neural Network (BPNN), Bayes, k-Nearest Neighbor (KNN), Decision Tree (DT), Random Forest (RF) and four sampling methods in the aspects of Detection rate and False alarm rate, and has better robustness for imbalanced classification.

Audio Encryption - A Chaos Based Data Byte Scrambling Technique
by Mohamed Parvees M Y, Abdul Samath J, Parameswaran Bose B
Abstract: This study proposes an efficient audio byte scrambling technique using multiple chaotic maps. The audio encryption scheme uses Henon map and chaotic economic map for creating sequences. The system uses an efficient algorithm which makes the sequences to interdependent with each other. This inter-dependency will add more sensitivity and complexity to the proposed algorithm. A repeated application of confusion and diffusion techniques on plain audio data bytes produces the cipher audio data bytes which can be stored or sent through the public channel. The detailed study of chaotic maps with respect to Lyapunov exponent and bifurcate nature, supports the proposed cryptosystem to behave chaotically, thereby produce highly secured cipher audio. The results of the various analyses including histogram, key space, key sensitivity, statistical, differential attack, entropy, mean-variance data bytes value and randomness analyses ensures the security of the audio encryption scheme against various kinds of attacks.
Keywords: Audio encryption; confusion; diffusion; chaotic map.
