Morphing Wing Concept for Small UAV

The biological flight involves the movement of a wing (lift surface) in viscous medium and it generates lift and resistance for going forward through friction compared to Reynolds number. The morphing concept is generally based on optimizing the aerodynamic form during the mission so it can execute a maneuver flight. This article desires a short passage through the mathematical aspect in 2D of the morphing profile concept.

Aspects Regarding the Performances of Small Swept Flying Wings Mini UAV-s in Aggressive Maneuvers

The UAS are largely used both in civilian and operational theatre missions. The current paper shows an examples for the turning and the spiral as simple maneuvers are also relevant to the development of new tactical capabilities of small UAS through improving the performance itself.

Emerging Applications of the New Paradigm of Intelligent Decision Making Process: Hybrid Decision Support Systems for Virtual Enterprise (DSS-VE)

In the aftermath of the recent global crisis, the modern firm should proactively respond to the disruptive changes in the dynamics of markets, new technologies and the new architec‐ ture of the competition. Shen, Norrie (1999) proposed the following set of capabilities for the next generation of production systems: the integration of the firm with all its management systems and their partners to better respond to the global competition and to the move‐ ments in the markets; distributed structure based on knowledge; heterogeneous environ‐ ments (software and hardware heterogeneous distributed in the production and operational environment); interoperability opened and capable to integrate new systems in an dynamic way; efficient cooperation with suppliers, partners and clients, integration human-machine; agility (the ability to adapt to a new environment in the case of rapid changing); scalability (additional resources could be easily incorporate) in every point location at every level with‐ out affection to the inter-organizational interdependencies; a good tolerance to different types of errors.

The Limits of Downsizing - A Critical Analysis of the Limits of the Agile Flying Wing MiniUAV

The missions of small flying wing UAVs require maneuver capabilities as well as optimal flight performance to balance the low operating and manufacturing costs. The basic principles in designing aviation structures must be readjusted due to the innovative concepts regarding the use of advanced materials as well as to the perspectives of using alternative energy aboard UAVs. The current paper is a synthesis of the 2D and 3D aerodynamic analysis of small swept flying wing UAVs that offers a global image of the possibilities of a multidimension optimization (miniaturization-scalability, payload-flexibility, minimum performances requirements).

A Hybrid Framework for SME Financing Based on the Mix between Governmental Support and the Use of a Specialized Investment Fund in the Actual Context of a Slow Recovery after Crises and Turbulences

Abstract The global crisis (2007-2009) and the European sovereign debt crises (2011-2013) have led to major changes in the SMEs financing. The recovery after the mentioned turbulences is slow and it requires the creation of new financial instruments that allow SMEs maintaining/ developing the existing business solution, but also the creation of new start-ups. In the emerging European countries the situation is even more critical because SMEs access to conventional financial solutions was seriously limited. Governments should respond more actively to solve the growing difficulties faced by SMEs in accessing finance (injections of capital in loan guaranteed programs, direct lending programs, micro-credit loans and other guaranties), but should be designed also other interesting innovative schemes (public-private partnership, special dedicated investment funds with flexible structure).

Applications of the Flexible Wing Concept at Small Unmanned Aerial Vehicles

Unmanned Aerial Vehicles have seen a rapid development due to increased miniaturisation of technology, and their multiple usages in both military and civilian fields, thus making this business very profitable. Although the small UAVs are high enabling capabilities, they are still single-role (one flight, one mission). The present paper will present a comparative analysis of the solutions on flexible wing concept and will analyze the possibilities to use the morphing concept at small UAVs.

Emerging Applications of Decision Support Systems (DSS) in Crisis Management

The recent financial crisis, the growth of the frequency of extreme risk events are motivations for a new analysis of the mechanisms and processes that implies high risk and high uncertainty. The new dynamics and the severe impact of the extreme events (natural hazards, terrorism, technological accidents, and economic/financial crises), but also the complexity of interventions have motivated the scientific community to find new efficient solutions for decision making process dedicated for crisis management, especially for solving the following aspects: time urgency, the complexity of event, the volatility/ rapidly changing of event/ decision conditions, the chaotic surrounding environment ingredient, the human behaviour in critical situations (emotional stress), the consequences for decision failure, poor data, frequent interruption during the decision making process. Extreme risk events are no longer only high impact low probability events. Indeed, the literature demonstrates that these types of events are more frequent and also their impact is also more critical. The governments are responsible not only for the post crisis management of extreme events. In this case, better knowledge could offer opportunities to reduce the impact. Emerging aspects regarding the integration of the concept of hybrid DSS in the treatment of extreme risk management will be presented. The efficiency of using intelligent ingredients in decision support systems (DSS) is linked to the human limits but also on the dynamics of huge data in the context of imprecision and uncertainty. Different applications for the use of hybrid DSS in flood and drought risk management, asymmetric risk and crisis management exercises will be also presented. Many extreme risk events are associated with modern human environment and in this case the spectrum of risks is changed with a difference between the perceived possibility and reality (Renn, 1992). Extreme risk is expressed by the potential for the realization of unwanted, adverse consequences to human life, health, property, or the environment. In Kaplan, Garrick (1981) is proposed the risk triplet (S-scenario, P-likelihood, D-possible consequence), a framework that responds to the nature of disaster events that can occur, how likely is a particular event, what are the consequences. Decision makers in extreme risk environments should respond in a new different manner because modern crisis management requires urgent developments toward better, more elaborated and appropriate means for extreme risks. Extreme risk management needs to

An analysis of the Innovative Financial Support of Space-Defense Investments

A key factor for the development of space-defense activities is the financial support, for which the government involvement continues to be the main funding stream. Depending on the development stage and application type, the overall funding stream may include industrial/ private equity and venture capital (VC) investors. Depending on the development stage and application type, some applications could be funded exclusively by and for government, but in other cases funding could be mixed. The private equity investors are rarely interested in the early stage technological development because of the risk-liquidity ratio or the uncertainty of future developments. The majority of space projects are selected for strategic, long term needs of their sponsors. Governments can stimulate alternative and innovative investment vehicles within space activities by leveling the risk that investors take, and supporting particular space activities through investment in actual portfolio products development and supporting this portfolio in the real market using innovative financing solutions. Governments can support actions that increase the risk to return ratio of innovative investments and these actions will always increase the efficiency of investments in space activities. Governments have the advantage of project portfolio management (PPM) under the authority of a specific directorate. Combining the advantages of PPM implementation alternative and innovative investments based on knowledge management could accelerate the evolution of technologies and value management could realize a robust implementation in the real market.

Using BDI Agents in Flexible Patterns for Cyber-Attacks over Electrical Power Infrastructures

This work aims to assess how the infrastructure of production & transport of the electric energy can be annihilated in a nation-state through a cyber attack, as a particular form of manifestation of cybernetic warfare. In this study we consider that the purpose of the cyber attack is only to remove servers from service, logically or physically. There are several standards that integrate the business side of a company with the level of supervision of industrial infrastructure and with the level of control engineering. These levels are integrated and are using different protocols. To simulate cyber-attacks between the countries with flexible potential escalation there are used BDI (Belief-Desire-Intention) agents which allow to separate treatment of different types of attacks. Inspired by the study of nuclear attacks implemented using the game theory, the flexibility of the BDI paradigm increases research potential of decision trees using this type of agent in other areas of human existence, like modeling human behavior at policy states makers or cyberspace executive users.

Innovative Instruments for SME Financing in Romania - a New Proposal with Interesting Implications on Markets and Institutions

Abstract The problem of SME manufacturing financing is already chronic in Romania. The banking system, on the one hand, still fails to sufficiently understanding on these projects, on the innovative character and the work model with intangible assets. On the other hand, the stock market is inaccessible for this type of investments. Investment funds are too focused on liability and indicial management. The government makes efforts to solve the problem of financing SME manufacturing, but there are no tools and no markets or appropriate institutional architecture. In this paper we propose not only new tools based on innovative mix of private management and governmental support of a new type of financial public -private partnership (PPP), but a way that creates a strong support of the markets and changing public perception about investments in capital markets. It first examines the possibility of creating a tool as closed end fund for SME manufacturing, the initial participation of the government will be 50%. It could be attracted foreign Venture Capital Fund (VCF) or Private Equity Fund (PEF) that already exist on the market and are interested in portfolio diversification. This fund can turn into semi-open in the background periodically be admitted new entries private. This fund can turn into semi-open fund in which periodically will be admitted new private entries. The fund may provide loans or, in a further development, may provide venture capital or private equity funding and at least we can start creating a framework for these new tools. Based on this proposal it is also possible to analyze another type of fund focused on co-financing mechanisms dedicated for national and European projects. In this case the main interest is to support liquidity management, consulting, to support warranties or windows settlement for different project phases.
