Nowadays, many organizations try to ensure the best result with the minimum necessary sources by following the practices of the propulsion of self-valuation throughout the European Foundation for Quality Management (EFQM) approach, within the frame of a Strategic Planning. The self-valuation criterions of the EFQM, can also be implemented in military units. The case of the EFQM self-valuation criterions’ implementation in a military Unit is examined in this study. It is tried a critical analysis of the case, by examining the following practice of its Commander within the context that his activities are emerged. Then, a particular proposal which concerns the implementation of the planning that follows the Johnson and Scholes (1993) model, is presented. The various manifestations and meanings of the self-valuation criterions and the useful tool of the Strategic Planning are revealed. Moreover, the characteristics of the leader-Commander are presented, so that the unit can meet the standards of the desired final state. The demand of active Commanders with vision, who can inspire the personnel by the proper guidance and the ability to convince them to follow the procedures, is the conclusion that comes out of the proposal. By carrying out a continuous self-valuation, within the frame of the EFQM criterions, and then, following the necessary actions, the improvement can be achieved. The personnel and the potential of its progress, the stuff maintenance, the facilities’ improvement, the exploration of the environment, in order recourses can be found, are the crucial factors so that actions can be taken over, which will targer to the exploitation of the unit’s potentials, the reduction of the threats and the weaknesses’ change into potentials. Commanding and leading skills are necessary with the simultaneous participation of all bodies in the various procedures. Yet, unpredictable situations, limitations and moral dilemmas may appear, making thus difficult Strategic Planning’s implementation.

Cemented Backfill

A novel and environmental-friendly backfill mining method known as upward slicing longwall-roadway cemented backfill (USLCB) technology has recently been proposed and successfully applied in mines extracting extra-thick coal seams located under sensitive areas. This paper studies the effects USLCB had on roof movement and failure behavior using the mechanical analysis approach. The application of USLCB in the Gonggeyingzi Mine is taken as a case study with roof movement behavior being monitored over a single mining cycle, as well as over multiple mining cycles of different coal slices. In addition, backfill performance requirements to prevent roof failures where USLCB is implemented are studied. The results show that the deflection curves of the roof at the end of each mining cycle during mining the first and the six slices are symmetrical, but they change from asymmetrical to symmetrical during the mining progresses of the second slice to the fifth slice. The final state of roof movement after the first slice, and through to the fifth slice, displays an obvious “flat bottom” pattern in the middle of the deflection curve. The roof movement during the removal of the top slice is noticeably different from other slices. The results also show that the requirements of the elastic modulus, as well as the strength of the backfill, increase as the number of mined slices increases from 1 to 5, but the requirements drop sharply for mining the top slice.

Quick Quantum Circuit Simulation (QQCS) is a software system for computing the result of a quantum circuit using a notation that derives directly from the circuit, expressed in a single input line. Quantum circuits begin with an initial quantum state of one or more qubits, which are the quantum analog to classical bits. The initial state is modified by a sequence of quantum gates, quantum machine language instructions, to get the final state. Measurements are made of the final state and displayed as a classical binary result. Measurements are postponed to the end of the circuit because a quantum state collapses when measured and produces probabilistic results, a consequence of quantum uncertainty. A circuit may be run many times on a quantum computer to refine the probabilistic result. Mathematically, quantum states are 2n -dimensional vectors over the complex number field, where n is the number of qubits. A gate is a 2n ×2n unitary matrix of complex values. Matrix multiplication models the application of a gate to a quantum state. QQCS is a mathematical rendering of each step of a quantum algorithm represented as a circuit, and as such, can present a trace of the quantum state of the circuit after each gate, compute gate equivalents for each circuit step, and perform measurements at any point in the circuit without state collapse. Output displays are in vector coefficients or Dirac bra-ket notation. It is an easy-to-use educational tool for students new to quantum computing.

Abstract Traditional MEMS (Micro-Electro-Mechanical Systems) devices have been with us for decades. A micromechanical motion sensor connected to the airbag electronics in your vehicle is always ready to send the instant message that can save your life. Sensing an abrupt change in motion indicating a crash, the MEMS accelerometer sends the command to fire the airbag. Today, multiple-axis motion-monitoring chips are on the market, so sensitive, that they can measure subtle hand motions. The ADI 202 will be demonstrated as part of this presentation. MEMS sensors are in wide use today but much more advanced activator type products are gaining market recognition as this technology advances. MOEMS (MicroOptoElectroMechanical Systems), or optical MEMS, adds “light” or optics to the technology cluster to provide the most advanced nano-devices yet. Texas Instruments is a pioneer in the MOEMS field with their highly successful Digital Micromirror Device (DMD™) now used in the best digital projectors and in cinemas. The DMD has more moving parts than a Boeing 777 and the Space Shuttle combined. We will do a case study of the DMD technology and review three products including “Redtooth” fiberless optics wireless. Optoelectronics, an “old-new” technology, is now the centerpiece of advanced communications especially for long-haul communications. A single optical fiber replaces over 4-million copper wires because of the unimaginable bandwidth resulting from the million-times higher frequency of light and the ability to multiplex hundreds of signals over a single fiber using Wave Division Multiplexing (WDM). But Internet links must be switched back and forth between electronic and photonic media. The reason is that routers and switches depend on electronics while transmission utilizes photonics. Many believe that MOEMS-based switches will solve the multiple conversion bottleneck allowing all-optical systems to smoothly handle traffic. So while MEMS, MOEMS and OE are separate, they all come together in fields like telecom. This paper will highlight these technologies and show how they will merge in an incredible future.
