    ABSTRACT: In spite of the importance of staying close to their buyers, many marketers feel it is impossible to identify needs for new products through marketing research. They feel that consumer respondents simply cannot describe their wants and needs for products which are not currently on the market. This paper describes two qualitative approaches for co-creating new product concepts with consumers. The two approaches involve (1) mini-concepts (verb-object combinations representing new product functions), and (2) casting ideas as "CADWOs" or, new products people feel they cannot do without

    ABSTRACT: Many vacuum electron devices are based on the interaction between an electron beam and the electromagnetic fields of resonators. Modeling and simulation of these devices became a key element in their development. The simulation code MAGY developed primarily to model gyrodevices, can treat structures which are axisymmetric and defined by a single-valued wall radius profile, rw(z). While this allows for the simulation of interaction structures consisting of simple pill box shaped cavities, it does not allow for the simulation of interaction structures with re-entrant cavities. We have developed and implemented a formulation in MAGY that can treat such cases. It consist of dividing space into a simulation region defined by a single-valued rw(z) and cavities external to this region. The fields in the cavities are expanded in modes and couple to the fields in the simulation region at the points on boundary, rw(z). The stability, convergence and accuracy issues of the new algorithm were studied. The results of MAGY simulations were compared with known analytical and numerical solutions for electron devices with external resonators. The advantages and limits of the new approach will be also discussed

    ABSTRACT: Numerical simulations have been carried out to investigate the performance of moderate-Z loads with higher current machines. In particular, the scaling of radiation emission with masses and velocities ranging from 0.5 mg/cm to 30 mg/cm, and from 30 cm/μs to 60 cm/μs respectively, have been considered. Such values are consistent with peak currents above 8 MA. The simulations which will be presented are focused on one-dimensional radiation hydrodynamic calculations where the risetime and peak power of the radiation pulse are considered to result primarily from the thermalization of kinetic energy at stagnation. To this end, the influence of electron-ion coupling and plasma opacity on radiative properties will be examined in detail. The importance of the two dimensional nature of the pinch and magnetic field effects will also be addressed for a small number of cases. The results of this study will be compared with recent experiments on the Z accelerator at Sandia National Laboratories where Titanium, Stainless Steel, and Copper arrays were used to look at scaling of K-shell emissions

    ABSTRACT: The aim of this paper is to explain how the research interests of a university group have been matched with the real needs of a distribution company team working in the field. It describes a case study of technology transfer, from research, through prototyping, to the market. This paper also addresses the formulation and the main evolutionary computation techniques used to deal with the problem of optimal distribution planning. The integration of all systems currently in operation is a priority of EDP distribution. The strategy is to arrive at a situation where those systems become modules of an integration platform. The infrastructure for this integration platform is a geographic information system. In the paper we describe the integration of DPlan in this platform

    ABSTRACT: Plasma Immersion Ion Implantation (PIII) applies a series of negative high-voltage pulses to a sample (target) immersed in plasma. PIII is a technology used to modify the material surface properties of a variety of products, e.g. for the manufacturing of semiconductor junctions and oxides, and for the production of high-strength, light-weight corrosion-resistant aerospace components. The pulse transformers become an essential part of the discharging circuit in a low impedance high-voltage pulser used with high impedance load such as PIII reactor. Summary form only given. The design and construction of high-voltage pulse transformer using metglas core are described and the analysis of a simplified lumped circuit model is used. It is found that a fast rise time requires low leakage inductance and low distributed capacitance and can be realized by reducing the number of secondary turns, but it produces larger pulse droop and requires a large core size. After careful choice of these parameters, a conventional pulse transformer with rise time less than 1 microsecond, and pulse droop of 1.5% has been built. The transmission characteristics and pulse time-response were measured. The agreement with the model was good when the measured values were used in the model simulation. The results of the high voltage test using PIII reactor as a load are also presented

    ABSTRACT: Summary form only given. The X pinch is an intense source of X-ray radiation in the 1.5-8 keV range. Individual x-ray sources produced within an X pinch exist for <1 ns and are emitted from a source <1 mum in diameter. In the past, spectroscopic investigations of the soft X-ray radiation emitted from X pinches have largely been limited to time-integrated measurements. These measurements indicated electron temperatures of 500-1300 eV, depending on wire material, and in some cases densities in excess of 10<sup>22</sup>/cm<sup>3</sup>. Additional measurements imply a volume power density> 10<sup>21</sup> W/cm<sup>3 </sup> and a surface flux > 10<sup>16</sup> W/cm<sup>2</sup> for the X-ray source. Time-resolved spectroscopic measurements of the radiation from X pinches will be presented that use a spherically bent mica crystal (R = 100-186 mm) and a Kentech X-ray streak camera with time resolution of <100 ps in a slitless scheme. The spectra of the soft X-ray radiation from. Al, Ti, NiCr, Nb and Mo X pinches obtained using Bragg angles near 45 degrees will be presented. The large angle allows us to place the crystal far from the X pinch, thereby preventing damage to the crystal and allowing a large spectral range. The previous time-integrated spectra and numerical spectral modeling were used to guide our choice of spectral lines that have been viewed with the streak camera. We will present time-resolved estimates for the electron temperature and density based on line ratios in H-, He-, and Ne-like ion spectra and/or the presence or absence of specific density-sensitive spectral lines

    ABSTRACT: The main purpose of this article is to inform about the studies being performed covering the 500 kV and 230 kV major substations of the North/Northeast (N/NE) Brazilian transmission system with respect to its intrinsic security, which includes the aspects of physical configuration of the buses, as well as the main and backup protection system philosophy used. Also, included as part of this article, are the solutions that are being proposed to improve the system general reliability, as well as the sectionalization of the main bus on substations with only one operating bus. The use of a PLC network to provide reconfiguration actions based on a multiple contingency criteria for situations, which may lead to system instability, or important loss of load is mentioned briefly. Finally, a few recommendations are presented for new substations, in order to improve their performance

    ABSTRACT: The hollow cathode plasma electron gun was designed especially for operation at forepump (up to 0.1 Torr) gas pressure. This work is devoted to investigation of maximum values of gas pressure and accelerating voltage It was established, that the maximum. operation gas pressure as well as the electron accelerating voltage increased with the smaller emission mesh size, shorter accelerating gap and lower plasma density. Physical model to explain experimental results has been created. This model takes into account plasma penetration from discharge unit into the acceleration gap as a main reason of high voltage breakdown. This penetration occurs if thickness of sheath, that separates plasma from the emission mesh, becomes smaller then the mesh hole. From the other hand the plasma density defines electron beam current. When it exceeds some value, electrical strength of accelerating gap increases. We suppose, it is due to gas heating and hence to neutral concentration drop, that in its turn leads to breakdown voltage growth. In our experiments we observed also increase of maximum values of gas pressure, accelerating voltage and beam current when axial magnetic field is applied. We refer these facts to account of prevention of penetrating plasma motion in radial direction and therefore limitation of plasma surface. Investigations and also modification of a construction allow us to improve parameters of electron gun. Now it provides I Amp electron beam with 10 keV energy. This progress allowed us to apply electron gun for beam-plasma discharge (BPD) initiation in hydrocarbon gas. At CH<sub>4</sub> pressure level 30-60 mtorr and electron beam current and energy 0.5 A and 2 kV we supervised DLC films deposition with high hardness and transparence. Deposition rates varied from 10 to 50 mcm/hour depending on experimental conditions

    ABSTRACT: Summary form only given. A semi-empirical model of helical magnetocumulative generators (MCGs) with a single adjustable parameter (called the characteristic time) has been developed and used to model several helical generators including the Mark IX, Flexy-I, EF-3 Ranchito, and Jemez generators. The model describes the time-dependent behavior of the output current of these generators. The calculated results are compared to those measured experimentally for all five generators. These comparisons will be presented in this paper along with initial thoughts on what physical factors influence the characteristic time

    ABSTRACT: A hybrid probabilistic/deterministic technique designated as the well-being approach is utilized in this paper to determine unit commitment in interconnected systems. Assessment of spinning reserve requirements in an interconnected generating system should include not only the generation and load models of the participating systems, but also the tie-line model and the agreement between the interconnected systems. A number of studies are illustrated to evaluate the impact on the interconnected system well-being indices of factors such as load forecast uncertainty, degree of generating unit postponability and derated states. The IEEE-RTS is used in this paper to illustrate these effects

    ABSTRACT: Summary form only given, as follows. A 9 cm Hall plasma source with a cusp type magnetic field distribution applied in a cylindrical ceramic channel exhibited discharge characteristics similar to conventional coaxial Hall thrusters. Probe measurements inside the plasma source indicated that localization of the acceleration and ionization regions depends strongly on the magnetic field distribution, but established mainly in the cylindrical part of the channel. In addition, ion flux measurements demonstrated high ionization efficiency of the cylindrical source in a broad range of gas flow rates and discharge voltages. The absence of the inner body in this novel plasma source enables miniaturization of the design and placement of segmented electrodes on the channel back wall to control the electric field distribution

    ABSTRACT: Summary form only given, as follows. A Z-pinch implosion is now commonly used as a K-shell plasma radiation source. The stability of the imploding shell is a key factor that limits the production of the K-shell radiation, especially, in the case of a long time implosion, or when the implosion starts from a large initial radius. Experiments carried out at HCEI and Maxwell-PI showed that the use of double shell gas puffs and solid fill loads could sufficiently improve implosion stability. As a next step in this direction, it was suggested to add hydrogen to a higher atomic number working gas in order to improve the implosion quality. Our 1D-RMHD modeling showed that the addition of hydrogen to the inner shell of double gas puffs leads to a decrease in K-shell radiation yield. However, if the gas mixture is used only in the outer shell, it can improve the stability of the outer shell implosion and the final pinch, so an increase in K-shell radiation production can be expected. We report the results of the double gas puff experiments carried out on the GIT-12 generator at the current level of 2.1-2.3 MA. In the experiments we used argon as a working gas in the inner shell and argon-hydrogen mixture in the outer shell

    ABSTRACT: In this paper, we propose the concept of "QOD (quality of driving)". We have developed a real-time system, which measures the stability of driving condition and evaluates the "QOD". There are several items to measure the stability of driving condition. So, we selected the following three parameters: "the degree of meandering", "the rightness of the velocity", and "the sufficiency of the distance between the driver's own vehicle and the other vehicle ahead". In our experiment, we installed a CCD camera on the dashboard of our vehicle, and we obtained three parameters form the sequence of the image taken by the camera, and evaluated the "QOD"

    ABSTRACT: This paper deals with the design and hardware implementation of two types of single-phase filter. The first type is the active shunt filter for compensating harmonic currents generated by nonlinear loads. The second type is the active series filter for eliminating harmonics inherent in the voltage source. The topology of the filter is based on a single-phase voltage source inverter (VSI) with four IGBT semiconductor switches. Simple time-domain extraction techniques are used to determine the harmonic components present in the load current or source voltage. The pulse-width-modulated (PWM) technique is then used to generate the required gate drive signals to the full-bridge VSI. A low-pass filter is also incorporated in the output of the inverter to provide a sufficient attenuation of the high switching ripples caused by the VSI

    ABSTRACT: In the paper the simulation results of ground-fault fast transients in stator windings of unit-connected generators are presented. The simulations were done for different elements connected between generator neutral and ground. Ungrounded neutral, neutral grounded through neutralisers or resistances were considered. The influence of the parameters of the particular grounding elements on the fast transient overvoltages during interrupted arcing ground-faults in the generator stator winding was determined. An additional capacitance to ground of the generator breakers, a real mechanism of ground-fault arc quenching, and real changes in its resistance during fast transients were also taken into account. Comparative simulations of the ground fault overvoltages for units with the biggest difference in parameters (in range 30-1600 MVA) were carried out. It has been found that for the grounding elements analysed the maximum overvoltages will not exceed double amplitude of the generator phase voltage

    ABSTRACT: Summary form only given. A low rep-rate and compact DPF neutron source, RDPF-2.2, was developed. The storing energy, maximum current and loop inductance are 2.2 kJ, 230 kA and 70 nH, respectively. At the repetitive rate of 1/66 Hz, the average and maximum neutron yield were measured as (4.9213.22)4107 and 2.24108 by a silver activation counter. In the condition of continuous operation for 100 shots without purging filling gas, before the fiftieth, the average neutron yield (ANY) in the sequence of the last six shots is almost the same as that of the first six shots. Then after the fiftieth, ANY decreases gradually, and the final ANY decreases to 40%. But the shots that the yield could be over 1.04108 occupy about 8% of the total shots. In addition, a CCD optical fibre spectrometer covering the wavelength range of 200-1100 nm was used to observe the spectra of the area (diameter of 12 mm) around the plasma focus. Basing on the continuous radiation spectrum of the observed spectra, the average electron temperature of the plasma was estimated as (25-766) eV. The intensity of deuterium spectral line decreases with increase of the neutron yield, whereas, the intensities of copper and iron spectral line increase with the neutron yield. It indicates that more electrode materials are spurted into plasma by stronger electron beams

    ABSTRACT: This paper explores the impact of six-phase transmission fine faults and their subsequent fault clearing and reclosing on the torsional torques induced in turbine-generator shafts. In this context, investigations have been conducted on a large turbine-generator unit connected to a sample power system. The paper also presents a comparison between the torsional stresses induced in the turbine-generator shafts during these events with their corresponding disturbances of a three-phase transmission system. The results of these investigations are presented in the form of typical time responses as well as parametric studies. The EMTP is used for the simulation studies. The studies conclude that six-phase transmission line faults generally induce torsional torques in the turbine-generator shaft whose magnitudes are relatively higher than those induced due to transmission line faults in a three-phase system. This conclusion is true for both sustained faults and faults followed by clearing and high-speed reclosing operations
