    Full Text Available The objective of this paper is to evaluate an innovative application of inductively coupled plasma atomic emission spectroscopy (ICP-AES on the fault diagnosis of automobile crane hydraulic power steering (HPS system. Contents of Fe, Cu and Al were examined by ICP-AES in the oil samples of HPS system for four different mileages of Puyuan QY50H. The mileages were 2000-9000 km, 11000-19000 km, 21000-28000 km and 32000-40000 km separately. Database of major mental contents in automobile crane HPS system of Puyuan QY50H with different mileage were calibrated. Results showed that, major mental contents were increased with the increasing of driving mileage and the normal contents laid between two trend lines. Through the determination of mental contents in HPS oil sample and further compared them with the values in their database, we could not only evaluate the wear condition of automobile crane HPS system, but also helped to diagnose the faults without dissembled the problematic vehicle. The results further indicated that, in time maintenance, high quality and low cost reparation could be realized by the application of ICP-AES technology on fault diagnosis of automobile crane power steering system.

  2. Study of automobile exhaust particles by spectromicroscopy

    International Nuclear Information System (INIS)

    In this paper,automobile exhaust particles of Gol and Santana 3000 were studied by spectro microscopy. The STXM results show that the single particulate is sized at 500 nm, with the mass distribution reducing towards the center. The N 1s NEXAFS spectra of automobile exhaust particles have similar structure with those of nitrates, which can be deduced as the main chemical species of nitrogen in automobile exhaust particles. There are minor amounts of ammonium and organic nitrogen compounds in automobile exhaust particles. A single Gol automobile exhaust particle was stack scanned in the energy range of 396-416 eV. By principal component analysis and cluster analysis, it can be deduced that there are main three chemical species of nitrogen. The particle surface consists of mainly nitrates, the inside consists of mainly ammonium and organic nitrogen compounds, and the middle layer is an inter gradation consisting of mainly nitrates and organic nitrogen compounds.

    2008-01-01

    We studied the information search behaviors of Chinese consumers of miniature automobiles. First, we identified the main sources where consumers acquire or seek information about miniature automobiles and discussed their extent of information search. Then, based on logistic regression and optimal scaling regression of statistics, we studied the influences of characteristics of consumers of miniature automobiles on the extent of information search and on Internet usage. The results indicate that consumers often utilize four sources to obtain information about miniature automobiles. The dominant information source for consumers is their friends/family, followed by dealers, newspapers, and TV. Age, occupation, education and income significantly affect the extent of information search, but gender and city of residence do not have significant impacts. Age, city of residence, occupation, education and income produce significant influences on Internet usage. Gender has an insignificant influence on whether a consumer uses the Internet to search for information.

    A study conducted to compare the technological status and the resultant potential vehicle characteristics for hydrogen- and battery-powered automobiles that could be produced from 1985 to 2000 is documented in 3 volumes. The primary objectives of the study were: the assessments of applicable energy storage and propulsion technology for the two basic vehicle types (applied to four-passenger cars); a rigorous comparison of vehicle weight, size, and usefulness versus design range; and an investigation of the relative efficiencies of expending energy from various primary sources to power the subject vehicle. Another important objective, unique to hydrogen powered vehicles, was the assessment of the technology, logistics, and cost implications of a hydrogen production and delivery capability. This volume, Volume III, contains three major sections: the assessment of battery electric vehicle technology for energy storage and the drivetrain system; the technical and economic comparison of hydrogen- and battery-powered vehicles derived primarily from data in the previous vehicle technology assessments, with consideration of alternative energy sources; and a series of appendices that support the vehicle definitions and comparisons.

  8. Nuclear power and carbon dioxide free automobiles

    International Nuclear Information System (INIS)

    Nuclear energy has been developed as a major source of electric power in Canada. Electricity from nuclear energy already avoids the emission of about 100 million tonnes of carbon dioxide to the atmosphere in Canada. This is a significant fraction of the 619 million tonnes of Canadian greenhouse gas emissions in 1995. However, the current scope of application of electricity to end use energy needs in Canada limits the contribution nuclear energy can make to carbon dioxide emission reduction. Nuclear energy can also contribute to carbon dioxide emissions reduction through expansion of the use of electricity to less traditional applications. Transportation, in particular contributed 165 million tonnes of carbon dioxide to the Canadian atmosphere in 1995. Canada's fleet of personal vehicles consisted of 16.9 million cars and light trucks. These vehicles were driven on average 21,000 km/year and generated 91 million tonnes of greenhouse gases expressed as a C02 equivalent. Technology to improve the efficiency of cars is under development which is expected to increase the energy efficiency from the 1995 level of about 10 litres/100 km of gasoline to under 3 litres/100km expressed as an equivalent referenced to the energy content of gasoline. The development of this technology, which may ultimately lead to the practical implementation of hydrogen as a portable source of energy for transportation is reviewed. Fuel supply life cycle greenhouse gas releases for several personal vehicle energy supply systems are then estimated. Very substantial reductions of greenhouse gas emissions are possible due to efficiency improvements and changing to less carbon intensive fuels such as natural gas. C02 emissions from on board natural gas fueled versions of hybrid electric cars would be decreased to approximately 25 million t/year from the current 91 million tonnes/year. The ultimate reduction identified is through the use of hydrogen fuel produced via electricity from CANDU power

    There is provided a climate control system for a parked vehicle that includes a solar panel, thermostatic switch, fans, and thermoelectric coolers. The solar panel can serve as the sole source of electricity for the system. The system affords convenient installation and removal by including solar panels that are removably attached to the exterior of a vehicle. A connecting wire electrically connects the solar panels to a housing that is removably mounted to a partially opened window on the vehicle. The thermostatic switch, fans, and thermoelectric coolers are included within the housing. The thermostatic switch alternates the direction of the current flow through the thermoelectric coolers to selectively heat or cool the interior of the vehicle. The interior surface of the thermoelectric coolers are in contact with interior heat sinks that have air circulated across them by an interior fan. Similarly, the exterior surface of the thermoelectric coolers are in contact with exterior heat sinks that have air circulated across them by an exterior fan.

    A thermal energy storage (TES) system developed for use with the Stirling engine as an automotive power system has gravimetric and volumetric storage densities which are competitive with electric battery storage systems, meets all operational requirements for a practical vehicle, and can be packaged in compact sized automobiles with minimum impact on passenger and freight volume. The TES/Stirling system is the only storage approach for direct use of combustion heat from fuel sources not suitable for direct transport and use on the vehicle. The particular concept described is also useful for a dual mode TES/liquid fuel system in which the TES (recharged from an external energy source) is used for short duration trips (approximately 10 miles or less) and liquid fuel carried on board the vehicle used for long duration trips. The dual mode approach offers the potential of 50 percent savings in the consumption of premium liquid fuels for automotive propulsion in the United States.

  11. Nonpolluting automobiles

    1994-11-01

    The advantages/disadvantages of energy storage devices, which can provide nonpolluting automobile systems are discussed. Four types of storage devices are identified: electrochemical (batteries); hydrogen; electromechanical (flywheels); and molten salt heat storage. A high-speed flywheel with a small permanent magnet motor/generator has more advantages than any of the other systems and might become a real competitor to the internal combustion engine. A flywheel/motor/generator system for automobiles now becomes practical, because of the technological advances in materials, bearings and solid state control circuits. The motor of choice is the squirrel cage induction motor, specially designed for automobile applications. The preferred controller for the induction motor is a forced commutated cycloconverter, which transforms a variable voltage/variable frequency source into a controlled variable-voltage/variable-frequency supply. A modulation strategy of the cycloconverter elements is selected to maintain a unity input displacement factor (power factor) under all conditions of loads voltages and frequencies. The system is similar to that of the existing automobile, if only one motor is used: master controller-controller-motor-gears (fixed)-differential-wheels. In the case of two motors, the mechanical differential is replaced by an electric one: master controller-controller-motor-gears (fixed)-wheel. A four-wheel drive vehicle is obtained when four motors with their own controllers are used. 24 refs.

    Fang, W.; Quan, S. H.; Xie, C. J.; Tang, X. F.; Wang, L. L.; Huang, L.

    2016-03-01

    In this study, a direct-current/direct-current (DC/DC) converter with maximum power point tracking (MPPT) is developed to down-convert the high voltage DC output from a thermoelectric generator to the lower voltage required to charge batteries. To improve the tracking accuracy and speed of the converter, a novel MPPT control scheme characterized by an aggregated dichotomy and gradient (ADG) method is proposed. In the first stage, the dichotomy algorithm is used as a fast search method to find the approximate region of the maximum power point. The gradient method is then applied for rapid and accurate tracking of the maximum power point. To validate the proposed MPPT method, a test bench composed of an automobile exhaust thermoelectric generator was constructed for harvesting the automotive exhaust heat energy. Steady-state and transient tracking experiments under five different load conditions were carried out using a DC/DC converter with the proposed ADG and with three traditional methods. The experimental results show that the ADG method can track the maximum power within 140 ms with a 1.1% error rate when the engine operates at 3300 rpm@71 NM, which is superior to the performance of the single dichotomy method, the single gradient method and the perturbation and observation method from the viewpoint of improved tracking accuracy and speed.

    Motivating employees begins with recognizing that to do their best work, people must be in an environment that meets their basic emotional drives to acquire, bond, comprehend, and defend. So say Nohria and Groysberg, of Harvard Business School, and Lee, of the Center for Research on Corporate Performance. Using the results of surveys they conducted with employees at a wide range of Fortune 500 and other companies, they developed a model for how to increase workplace motivation dramatically. The authors identify the organizational levers that companies and frontline managers have at their disposal as they try to meet workers' deep needs. Reward systems that truly value good performance fulfill the drive to acquire. The drive to bond is best met by a culture that promotes collaboration and openness. Jobs that are designed to be meaningful and challenging meet the need to comprehend. Processes for performance management and resource allocation that are fair, trustworthy, and transparent address the drive to defend. Equipped with real-world company examples, the authors articulate how to apply these levers in productive ways. That application should not be selective, they argue, because a holistic approach gets you more than a piecemeal one. By using all four levers simultaneously, and thereby tackling all four drives, organizations can improve motivation levels by leaps and bounds. For example, a company that falls in the 50th percentile on employee motivation improves only to the 56th by boosting performance on one drive, but way up to the 88th percentile by doing better on all four drives. That's a powerful gain in competitive advantage that any business would relish.

    2016-08-01

    To make full use of the maximum output power of automobile exhaust thermoelectric generator (AETEG) based on Bi2Te3 thermoelectric modules (TEMs), taking into account the advantages and disadvantages of existing maximum power point tracking methods, and according to the output characteristics of TEMs, a hybrid maximum power point tracking method combining perturb and observe (P&O) algorithm, quadratic interpolation and constant voltage tracking method was put forward in this paper. Firstly, it searched the maximum power point with P&O algorithms and a quadratic interpolation method, then, it forced the AETEG to work at its maximum power point with constant voltage tracking. A synchronous buck converter and controller were implemented in the electric bus of the AETEG applied in a military sports utility vehicle, and the whole system was modeled and simulated with a MATLAB/Simulink environment. Simulation results demonstrate that the maximum output power of the AETEG based on the proposed hybrid method is increased by about 3.0% and 3.7% compared with that using only the P&O algorithm and the quadratic interpolation method, respectively. The shorter tracking time is only 1.4 s, which is reduced by half compared with that of the P&O algorithm and quadratic interpolation method, respectively. The experimental results demonstrate that the tracked maximum power is approximately equal to the real value using the proposed hybrid method,and it can preferentially deal with the voltage fluctuation of the AETEG with only P&O algorithm, and resolve the issue that its working point can barely be adjusted only with constant voltage tracking when the operation conditions change.

    The apparatus would include a solar photovoltaic panel mounted on the roof and a panellike assembly mounted in a window opening. The window-mounted assembly would include a stack of thermoelectric devices sandwiched between two heat sinks. A fan would circulate interior air over one heat sink. Another fan would circulate exterior air over the other heat sink. The fans and the thermoelectric devices would be powered by the solar photovoltaic panel. By means of a double-pole, double-throw switch, the panel voltage fed to the thermoelectric stack would be set to the desired polarity: For cooling operation, the chosen polarity would be one in which the thermoelectric devices transport heat from the inside heat sink to the outside one; for heating operation, the opposite polarity would be chosen. Because thermoelectric devices are more efficient in heating than in cooling, this apparatus would be more effective as a heater than as a cooler. However, if the apparatus were to include means to circulate air between the outside and the inside without opening the windows, then its effectiveness as a cooler in a hot, sunny location would be increased.

    Technical and economic feasibility studies on a small windmill to provide overnight charging for an electrically driven car are reported. The auxiliary generator provides power for heating and cooling the vehicle which runs for 25 miles on battery power alone, and for 50 miles with the onboard charger operating. The blades for this windmill have a diameter of 12 feet and are coupled through to a conventional automobile alternator so that they are able to completely recharge car batteries in 8 hours. Optimization of a windmill/storage system requires detailed wind velocity information which permits rational sitting of wind power system stations.

    While a number of automotive fuel cell applications have been demonstrated, including a golf cart, buses, and a van, these systems and others that have been proposed have utilized differing configurations ranging from direct hydrogen fuel cell-only power plants to fuel cell/battery hybrids operating on reformed methanol. To date there is no clear consensus on which configuration, from among the possible combinations of fuel cell, peaking device, and fuel type, is the most likely to be successfully commercialized. System simplicity favors direct hydrogen fuel cell vehicles, but infrastructure is lacking. Infrastructure favors a system using a liquid fuel with a fuel processor, but system integration and performance issues remain. A number of studies have analyzed particular configurations on either a system or vehicle scale. The objective of this work is to estimate, within a consistent framework, fuel economies and ranges for a variety of configurations using flexible models with the goal of identifying the most promising configurations and the most important areas for further research and development.

    2000-02-01

    In this article, we introduce the Multi-Motive Grid (MMG), a new diagnostic tool to measure motives with respect to their hope and fear components. The MMG combines features of the Thematic Apperception Test (TAT) with features of self-report questionnaires. Similar to the TAT, a set of 14 pictures representing a balanced set of achievement-arousing, affiliation-arousing, and power-arousing situations is presented together with a set of statements representing important motivational states. Six motive scores can be calculated: hope of success (HS) and fear of failure (FF) for the achievement motive, hope of affiliation (HA) and fear of rejection (FR) for the affiliation motive, and hope of power (HP) and fear of power (FP) for the power motive. Results of factor analyses suggest a 3-factor solution, with a general fear factor (FF, FR, FP), a factor combining the hope components of achievement and power (HS and HP), and a third factor representing HA, but the 6 a priori factors also reflect a sound structural model. Reliability data show that the internal consistency and retest reliability of the MMG scales satisfy traditional standards. External validity of the MMG has been established in all 3 motive domains. Three separate studies document that (a) individuals high in resultant achievement motivation perform better and report more flow experience, (b) individuals high in resultant power motivation profit more from a leadership training program, and (c) individuals high in resultant affiliation motivation recollect more highly memorable affiliative themes.

    This study investigated the relationship between pneumatic nutrunner handle reactions, workstation characteristics, and prevalence of upper limb injuries in an automobile assembly plant. Tool properties (geometry, inertial properties, and motor characteristics), fastener properties, orientation relative to the fastener, and the position of the tool operator (horizontal and vertical distances) were measured for 69 workstations using 15 different pneumatic nutrunners. Handle reaction response was predicted using a deterministic mechanical model of the human operator and tool that was previously developed in our laboratory, specific to the measured tool, workstation, and job factors. Handle force was a function of target torque, tool geometry and inertial properties, motor speed, work orientation, and joint hardness. The study found that tool target torque was not well correlated with predicted handle reaction force (r=0.495) or displacement (r=0.285). The individual tool, tool shape, and threaded fastener joint hardness all affected predicted forces and displacements (paverage peak handle force and displacement for right-angle tools were twice as great as pistol grip tools. Soft-threaded fastener joints had the greatest average handle forces and displacements. Upper limb injury cases were identified using plant OSHA 200 log and personnel records. Predicted handle forces for jobs where injuries were reported were significantly greater than those jobs free of injuries (ppower hand tool operations and for controlling exposure to forces in manufacturing jobs involving power nutrunners.

    Motivation is short-term focused energy. The oldest theories of motivation explain motivated activity as effort to overcome primary deficiencies, such as hunger or boredom. Such theories are difficult to apply because individuals learn idiosyncratic secondary motives as alternative ways of responding to these needs. Three prominent needs theories are discussed: Herzberg's theory of hygiene and motivational factors; McClelland's needs for achievement, power, and affiliation; and Maslow's hierarchy and theory of self-actualization. A second approach to motivation holds that individuals may be thought of as engaging in rational processes to maximize their self-interests. The presented examples of this approach include Vroom's expectancy theory, Adam's theory of inequality, and the Porter-Lawler model that addresses the question of whether satisfaction leads to high performance or vice versa. Finally, several theories of motivation as life orientation are developed.

  13. Recruiting, training, and motivation of power plant personnel

    International Nuclear Information System (INIS)

    Incidents in nuclear power plants may be caused by human failure. The shift personnel plays a key role. Recruting of shift personal is usually difficult, a compromise must be made with regard to qualification. Training is tedious and costly. After basic training, knowledge must be maintained and deepened in refresher courses. However, especially experimence shift staff tend to fluctuate, so that motivation requires great consideration. For the supervising engineers, a picket service has been organized in order to assure that in case of emergencies, there will be an engineer immediately to control power plant operation. This organisation structure has shown good results in both power plants and will be taken over by other swiss nuclear power plants. (orig./GL)

    The microstructure, mechanical properties, and misorientation of automobile beam steels produced by EAF-CSP process were studied using optical microscopy (OM) and electron back-scattered diffraction (EBSD). It is shown that the microstructure of strips is mainly polygonal ferrite, and the average grain size is about 5-8 μm. The electron back-scattered diffraction results show that grain boundaries in ferrite are basically high-angle grain boundaries without remarkable preferred orientation. Hot strips of automobile beam steels possess a good combination of strength and plasticity because of their fine microstructures and low quantity of impurities.

    Diesel exhaust particles are known to contain mutagenic and carcinogenic chemicals. The aim of this study was to determine whether, and to what extent, catalytic particulate trap oxidizers on light-duty diesel engines may reduce the emission of particle-associated mutagenic chemicals into the environment. Exhaust particles were collected from Mercedes Benz and Volkswagen diesel automobiles, equipped with or without the manufacturer's exhaust traps, while running on a chassis dynamometer under specified load conditions. Exhaust particles were collected from a dilution tunnel onto 20" X 20" Teflon-coated fiberglass filters. Mutagenesis tests of dichloromethane (DCM) extracts of the particles were conducted using the Ames Salmonella bacterial test system. The mutation rate was calculated in terms of histidine revertants per mile of travel during a set of standard test cycles. With both vehicles the traps produced an 87-92% reduction in the total amount of particulate material collected by the filters. There was no significant change in the specific mutagenic activity (revertants per microgram of DCM particle extract) with or without the traps. These studies support the notion that installation of exhaust traps which reduce particulate emission on diesel-powered vehicles will also reduce the emission of particle-associated mutagenic and carcinogenic materials into the environment.

    With mandates and regulatory policies to meet both the California Air Resources Board (CARB) and the Partnership for a New Generation of Vehicles (PNGV), designing vehicles of the future will become a difficult task. As we look into the use of electric and hybrid vehicles, reduction of the required power demand by influential automobile components is necessary in order to obtain performance and range goals. Among those automobile components are accessories. Accessories have a profound impact on the range and mileage of future vehicles with limited amounts of energy or without power generating capabilities such as conventional vehicles. Careful assessment of major power consuming accessories helps us focus on those that need improvement and contributes to attainment of mileage and range goals for electric and hybrid vehicles.

    The dynamic continuous cooling transformation (CCT) diagram and phase transformation rules of 510 MPa automobile beam steel, which is produced by a continuous casting of thin slab of FTSR technology in Tangshan Iron and Steel Co. Ltd. , are researched by thermal simulation experiment. The mierostructure characteristics of the beam steel under different test conditions are studied by means of optical microscope and scanning electron microscope. The test results show that the critical temperatures of phase transformation Ar3 and Ar1 will all decrease with the increase of the cooling rate. When the cooling rate is lower than 20℃·s-1, the ferrite and pearlite phase transformations are the main parts; when the cooling rate is higher than 20℃· s-1, the bainite phase appears. Moreover, the microstructurea of 510 MPa automobile beam steel produced by FTSR technology are also studied, and the results are basically in accordance with the CCT diagram gained from the test.

    Similarities and differences in physico-chemical and optical properties of combustion generated particles from various sources were investigated. Coal-fired power plant, charcoal kiln, automobile and ship engine were major sources, representing combustions of coal, biomass and two different types of diesel, respectively. Scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray spectroscopy (EDX) equipped with both SEM and HRTEM were used for physico-chemical analysis. Light absorbing properties were assessed using a spectrometer equipped with an integrating sphere. Particles generated from different combustion sources and conditions demonstrate great variability in their morphology, structure and composition. From coal-fired power plant, both fly ash and flue gas were mostly composed of heterogeneously mixed mineral ash spheres, suggesting that the complete combustion was occurred releasing carbonaceous species out at high temperature (1200-1300 °C). Both automobile and ship exhausts from diesel combustions show typical features of soot: concentric circles comprised of closely-packed graphene layers. However, heavy fuel oil (HFO) combusted particles from ship exhaust demonstrate more complex compositions containing different morphology of particles other than soot, e.g., spherical shape of char particles composed of minerals and carbon. Even for the soot aggregates, particles from HFO burning have different chemical compositions; carbon is dominated but Ca (29.8%), S (28.7%), Na(1%), and Mg(1%) are contained, respectively which were not found from particles of automobile emission. This indicates that chemical compositions and burning conditions are significant to determine the fate of particles. Finally, from biomass burning, amorphous and droplet-like carbonaceous particles with no crystallite structure are observed and they are generally formed by the condensation of low volatile species at low

    Full Text Available The aim of three studies was to examine the differences between business majors and non-business majors, in their level of implicit (measured by an Implicit Association Test [IAT], Greenwald, McGhee, & Schwarz, 1998 and explicit power motivation (measured by Power Motivation and Helping Power Motivation scales, Frieze & Boneva, 2001.It was predicted that there are no differences between these two groups in the general (implicit level of power motivation, but that differences exist in the way it is explicitly expressed: through desire for leadership and prominence vs. desire for helping. Results of Study 1 indicated that business majors (management, N=79 declared a higher leadership motive and a lower helping motive than non-business majors (history, psychology, linguistics, N=62.Study 2 addressed question whether the above differences in power motivation stem from socialization at the university level or from pre-selection. The relationship between high school students’ (N=134 academic major preferences and their power motivation was tested. It was found that the more they were business-oriented, the higher their scores were on leadership, and lower on helping scales. In Study 3, business majors (economics, N=75 and non-business majors (psychology, N=82 completed the same questionnaire as participants in previous studies, as well as performed the IAT. Non-business majors declared stronger explicit helping motive, while business majors expressed stronger prominence and leadership motives. Furthermore, for non-business majors, IAT results could be predicted by their helping score. Implications and possible limitations of the presented results are discussed.

    Following up on earlier research suggesting a link between implicit affiliation motivation and progesterone (P) and implicit power motivation and testosterone [T; Schultheiss, O.C., Dargel, A., Rohde, W., 2003. Implicit motives and gonadal steroid hormones: Effects of menstrual cycle phase, oral contraceptive use, and relationship status. Horm. Behav. 43, 293-301.], we tested whether arousal of affiliation motivation increases P levels and whether arousal of power motivation increases T levels. Sixty subjects were randomly assigned to watch 30 min of either Bridges of Madison County (affiliation arousal) or The Godfather II (power arousal), or a documentary about the Amazon (control condition). Levels of P and T were assessed in saliva samples taken before (T1), immediately after (T2), and 45 min after the movie (T3). The efficacy of experimental conditions to differentially arouse motives was verified by assessment of changes in affiliation and power motive imagery expressed in imaginative stories written before and after the movie. After the movie, salivary P levels (T2 and T3) in the affiliation-arousal group were significantly higher than in the control group and marginally higher than in the power-arousal group. Subjects' postmovie T responses (T3) depended on premovie T levels: in men, higher premovie T levels predicted a greater likelihood of postmovie T increases in the Power Arousal condition but not in the other conditions, whereas in women, higher premovie T levels tended to be associated with postmovie T decreases in the Power Arousal condition but not in the other conditions. These findings suggest that aroused affiliation motivation has a specific stimulatory effect on P, whereas aroused power motivation has a specific stimulatory effect on T in men, but not in women, with high baseline T levels.

    Increasing motivation can positively impact cognitive performance. Here we employed a cognitive timing task that allows us to detect changes in cognitive performance that are not influenced by general activity or arousal factors such as the speed or persistence of responding. This approach allowed us to manipulate motivation using three different methods; molecular/genetic, behavioral and pharmacological. Increased striatal D2Rs resulted in deficits in temporal discrimination. Switching off the transgene improved motivation in earlier studies, and here partially rescued the temporal discrimination deficit. To manipulate motivation behaviorally, we altered reward magnitude and found that increasing reward magnitude improved timing in control mice and partially rescued timing in the transgenic mice. Lastly, we manipulated motivation pharmacologically using a functionally selective 5-HT2C receptor ligand, SB242084, which we previously found to increase incentive motivation. SB242084 improved temporal discrimination in both control and transgenic mice. Thus, while there is a general intuitive belief that motivation can affect cognition, we here provide a direct demonstration that enhancing motivation, in a variety of ways, can be an effective strategy for enhancing temporal cognition. Understanding the interaction of motivation and cognition is of clinical significance since many psychiatric disorders are characterized by deficits in both domains.

    2011-06-01

    Full Text Available Code Recognition Device is a security device for automobiles. It responds only to the right sequence of codes that are keyed from the key pad. This closes the electrical circuitry of the automobile and enables it to start. If a wrong key is touched, it resets the device which disengages the electrical circuit of the automobile from the power supply. The device works properly on closing all the doors of the automobile, otherwise it cannot start. Also, once the automobile is in operation, opening of any door will disengage the device and the engine will stop. To restart the engine, the doors must be closed and the codes rendered sequentially-in this case the codes are 1974.

    Ultraviolet radiation (UVR) has known adverse effects on the skin and eyes. Practitioners are becoming more aware of the importance of outdoor photoprotection. However, little attention is directed to the exposure of the skin and eyes to UVR through the window glass or sunglasses. The amount of ultraviolet transmission through glass depends mainly on the type of the glass. All types of commercial and automobile glass block the majority of ultraviolet-B; however, the degree of ultraviolet-A transmission depends on the type of glass. Laminated glass offers better UVA protection than tempered glass; new safety regulations for automobiles may result in increased use of laminated glass for side windows. Window films can be applied to glass to increase UVR protection. Sunglasses need to be compliant with one of the national standards; a wraparound style or side shields offer the best protection. Increased understanding by practitioners on the transmission of UVR through glass, window films, and sunglasses would allow them to better educate the public and to better manage photosensitive patients.

    Full Text Available The fundamental aims of sustainable urban development and the pro-automobile oriented economic development are on a collision course. It is obvious that automobile-dependent urban development is under heavy/powerful influence of the automobile lobby (automobile and oil industries, along with construction. In this domain famous land-use-transportation studies (or ‘grand transportation studies’ are, unfortunately, still prevailing - a vicious circle of self-fulfilling prophecy of congestion, road building, sprawl, congestion and more road building. Until recently, it was commonly thought that investment in public transport was not economically sustainable and that focusing on the development of the automobile industry and financing the construction of roadways stimulated economic growth. In this paper we clearly show that automobile industry is now overcapitalized, less profitable than many other industries (and may become even less profitable in the future, that transport market is characterized with huge distortions (more than a third of motor-vehicle use can be explained by underpriced driving, while new road investment does not have a major impact on economic growth (especially in a region with an already well-developed infrastructure, and that pro-automobile transport strategy inexorably incurs harmful global, regional and local ecological consequences.

    Full Text Available Implicit motives like the need for power (nPower scale affective responses to need-specific rewards or punishments and thereby influence activity in motivational-brain structures. In this paper, we review evidence specifically supporting a role of the striatum in nPower. Individual differences in nPower predict (a enhanced implicit learning accuracy, but not speed, on serial-response tasks that are reinforced by power-related incentives (e.g., winning or losing a contest; dominant or submissive emotional expressions in behavioral studies and (b activation of the anterior caudate in response to dominant emotional expressions in brain imaging research. We interpret these findings on the basis of Hikosaka, Nakamura, Sakai, and Nakahara's (2002; Current Opinion in Neurobiology, 12(2, 217-222 model of central mechanisms of motor skill learning. The model assigns a critical role to the dorsoanterior striatum in dopamine-driven learning of spatial stimulus sequences. Based on this model, we suggest that the dorsoanterior striatum is the locus of nPower-dependent reinforcement. However, given the centrality of this structure in a wide range of motivational pursuits, we also propose that activity in the dorsoanterior striatum may not only reflect individual differences in nPower, but also in other implicit motives, like the need for achievement or the need for affiliation, provided that the proper incentives for these motives are present during reinforcement learning. We discuss evidence in support of such a general role of the dorsoanterior striatum in implicit motivation.

    In this paper, a thermal elastic-plastic finite element method (FEM) is used to simulate the plasma welding process in order to predict the welding distortion of automobile stator iron core. Six spatial symmetrical welding torches are adopted in the welding process so as to make the iron core rings welded firmly and the distortion symmetric. The effect of rigid clamp on actual welding process is replaced by the contact function between rigid body and deformation element in the MSC software, MARC. The welding process restrained by clamp and deformation analysis after the removal of clamp was successfully simulated. The predictions show good agree-ment with the test results when the rigid clamps are taken into account in the welding simulation, which satisfies the design requirement for manufacture.

    Cross wedge rolling with multi-wedge (MCWR) is a new advanced technology of forming the slandering of automobile semi-axes. However, restriction relationship between main wedges and side wedges is complex, there is not almost theory forming automobile axes at inland or overseas. According to the characteristics of forming slandering of automobile semi-axes by MCWR, three-dimensional parameterized model of the MCWR and corresponding program of finite element simulation is worked out. Adopting FEM analysis technology, rules of stress distribution in work piece at main stages, such as knifing zone, stretching zone in main wedges was investigated. The results indicate that forming automobile semi-axes by MCWR is feasible.

    This study tested the hypothesis that implicit power motivation (nPower), in interaction with power incentives, influences activation of brain systems mediating motivation. Twelve individuals low (lowest quartile) and 12 individuals high (highest quartile) in nPower, as assessed per content coding of picture stories, were selected from a larger initial participant pool and participated in a functional magnetic resonance imaging study during which they viewed high-dominance (angry faces), low-dominance (surprised faces) and control stimuli (neutral faces, gray squares) under oddball-task conditions. Consistent with hypotheses, high-power participants showed stronger activation in response to emotional faces in brain structures involved in emotion and motivation (insula, dorsal striatum, orbitofrontal cortex) than low-power participants.

  6. Energizing porters by proton-motive force.

    1994-11-01

    It is generally accepted that the chemistry of water was the most crucial determinant in shaping life on earth. Among the more important chemical features of water is its dissociation into protons and hydroxyl ions. The presence of relatively high proton concentrations in the ambient solution resulted in the evolution of proton pumps during the dawn of life on earth. These proton pumps maintained neutral pH inside the cells and generated electrochemical gradients of protons (proton-motive force) across their membranes. The existence of proton-motive force enabled the evolution of porters driven by it that are most probably among the more primitive porters in the world. The directionality of the substrate transport by the porters could be to both sides of the membranes because they can serve as proton symporters or antiporters. One of the most important subjects of this meeting is the mechanism by which proton-motive and other ion-motive forces drive the transport processes through porters. Is there a common mechanism of action for all proton-driven porters? Is there some common partial reaction by which we can identify the way that porters are energized by proton-motive force? Is there a common coupling between proton movement and uptake or secretion of certain molecules? Even a partial answer to one of these questions would advance our knowledge... or confusion. As my mentor Efraim Racker used to say: 'If you are not totally confused you do not understand the issue'. PMID:7823046

    Full Text Available Unmodified montmorillonite clay was utilized as a low cost adsorbent for the removal of heavy metals from a contaminated automobile effluent. Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy were used to characterize the adsorbent. Batch sorption experiments were performed at an optimum effluent pH of 6.5, adsorbent dose of 0.1 g, particle size of 100 μm and equilibrium contact time of 180 min. Thermodynamic analysis was also conducted. Equilibrium data were analyzed by the Langmuir, Freundlich, Temkin and Dubinin–Radushkevich models. A heterogeneous surface of the adsorbent was indicated by the Freundlich model. The Langmuir maximum adsorption capacity of the montmorillonite for metals was found in the following order: Zn (5.7 mg/g > Cu (1.58 mg/g > Mn (0.59 mg/g > Cd (0.33 mg/g > Pb (0.10 mg/g ≡ Ni (0.10 mg/g. This was directly related to the concentration of the metal ions in solution. The pseudo-first order, pseudo-second order, intraparticle diffusion and liquid film diffusion models were applied for kinetic analysis. The mechanism of sorption was found to be dominated by the film diffusion mechanism. The results of this study revealed the potential of the montmorillonite for treatment of heavy metal contaminated effluents.

    The PIXE technique has been successfully applied to investigate the environmental problems caused by the studded tire of automobiles. The dust samples were collected on stacked filters in Sapporo and some other cities in Japan and Europe. PIXE measurements were performed using a 2 MeV proton beam. The results were compared with those of different cities. The main components of dust particulates were Al, Si, Ca, Fe and so on. The vertical distribution of dust concentration in the city of Sapporo was determined by PIXE in April and June. The concentration in April decreases exponentially with height from the ground. The effect of dust particulates due to studded tires is observed up to an altitude 60 m. On the other hand in June, the concentration on the ground is one-tenth of that in April, and it is almost unchanged with the distance in the vertical direction. The concentration of Ca in the dust particulates in the area where the studded tires are used increases by a factor of 2 to 4 in comparison with that in the ordinary soil.

  11. Rapid measurement of spatial gamma-ray by using automobile (ship)

    International Nuclear Information System (INIS)

    The methods of car-borne measurement of terrestrial radioactivity are described. The in-situ gamma-ray spectrometry was made by using a multichannel pulse height analyzer with a NaI(T1) scintillation detector loaded on an automobile. The continuous recording of car-borne measurement was performed. The result of measurement in a tunnel showed the geological features. A map of the radiation level in Mihama Town was made from the result of measurement. A portable multi-channel survey meter was designed and constructed to identify the component of radiation. By using this survey meter, the investigation of the environmental radiation level in Noto Peninsula in Ishikawa Prefecture was performed. The results showed the state of geological features and the decrease of cosmic ray component in a tunnel. It is possible to load the detector on a ship. The spatial distribution of radiation on the sea was measured. The effects of rocks, a bridge and banks were seen. (Kato, T.)

  12. Plant pollution from lead produced by automobile exhaust system near certain highways of Iran

    International Nuclear Information System (INIS)

    Plants polluted with Pb produced by automobiles along the roads and highways have extensively been reported all over the world. It is the most important source of pollution in the environment. This research was carried out to determine the polluting degree of plants along the highways such as: Rasht-Anzaly, Kelachay-Ramsar, Tehran-Karaj, and Isfahan-Tehran. At each arbitrary point, a transect 100 meters long perpendicular to the highway was selected for sampling. Along each transect, plants were sampled at 15 cm above the ground, in different distances from the highway. Samples were transported to the laboratory and analyzed by a standard method. The average concentration of total Pb determined in Anzali, Ramsar, Karaj and Delijan (east and west of the road) areas respectively were 114.5, 58.3, 260.2, 75.1 and microgram per gram dry plant weight. Total Pb content in plants along the roads were high and exponentially decreasing with distance from the roadside. Pb concentration in plants were higher than threshold of Standard, so the risk of entrain g of this poisonous element in nutrition system along the roads is very considerable. The plants were polluted from medium degree up to a very high degree. The rate of pollution in plant samples is very high in Karaj area, high in Anzali area, and medium in Ramsar and Delijan areas. Plant pollution was directly related to the traffic volume in road

  13. Concentration and distribution of platinum-group elements (PGE) in soils. Platinum emission by attrition of automobile exhaust catalysts

    International Nuclear Information System (INIS)

    In Germany automobile exhaust control by platinum-group element (PGE) loaded catalysts is now well established. By mechanical or chemical attrition, these catalysts could act as a potential source for a significant increase of PGE abundances in the environment. During a recent research program concentrations and distributions of PGE in different soils were measured along the highway A66 Frankfurt - Wiesbaden. 71 nearsurface soil samples were analysed by graphite furnace atomic absorption spectrometry (GFAAS). The results revealed average abundances of 10 ppb platinum and 3 ppb ruthenium. Palladium as well as rhodium were below the analytical detection limit of 2 ppb. With increasing distance from the highway edge PGE values gradually decreased. Only the upmost soil layer, down to 20 cm depth, contains measurable PGE concentrations. Results: There are irregular PGE concentrations of anthropogenic origin in different soils along the highway A66 Frankfurt -Wiesbaden possibly arising from automobile exhaust catalysts. Further monitoring could help to avoid potential environmental hazards. (orig.)

    This study investigated the effect of interpersonal power on co-operative performance. We used a paired electro-encephalogram paradigm: pairs of participants performed an attention task, followed by feedback indicating monetary loss or gain on every trial. Participants were randomly allocated to the power-holder, subordinate or neutral group by creating different levels of control over how a joint monetary reward would be allocated. We found that power was associated with reduced behavioural accuracy. Event-related potential analysis showed that power-holders devoted less motivational resources to their targets than did subordinates or neutrals, but did not differ at the level of early conflict detection. Their feedback potential results showed a greater expectation of rewards but reduced subjective magnitude attributed to losses. Subordinates, on the other hand, were asymmetrically sensitive to power-holders' targets. They expected fewer rewards, but attributed greater significance to losses. Our study shows that power corrupts balanced co-operation with subordinates.

    This paper investigates the characteristics of automobile accidents by taking into account two types of automobile insurance coverage: comprehensive vehicle physical damage insurance and voluntary third-party liability insurance. By using a unique data set in the Taiwanese automobile insurance market, we explore the bundled automobile insurance coverage and the occurrence of claims. It is shown that vehicle physical damage insurance is the major automobile coverage and affects the decision to purchase voluntary liability insurance coverage as a complement. Moreover, policyholders with high vehicle physical damage insurance coverage have a significantly higher probability of filing vehicle damage claims, and if they additionally purchase low voluntary liability insurance coverage, their accident claims probability is higher than those who purchase high voluntary liability insurance coverage. Our empirical results reveal that additional automobile insurance coverage information can capture more driver characteristics and driving behaviors to provide useful information for insurers' underwriting policies and to help analyze the occurrence of automobile accidents.

    Hot stamping 22MnB5 steel plate with ultra-high strength has been widely used for body structural members in consideration of automobile safety and lightweight. This paper presents a verification program of simulating and testing pole impact in order to verify if the front crossbeam reinforcement assembly can meet the design requirements, reduce the overall vehicle simulation and test cost and shorten the operation period. In the same condition, the simulation proved conforming to the design requirements; however, the bumper cracked at the impacting point in the course of pole impact test. The analysis of the crack by optical microscope, Vickers and scanning electron microscope indicates that mixture of ferrite, bainite and martensite was produced in the weld heat-affected zone of the 340/590DP tow hook holder and the 22MnB5 front crossbeam; therefore, their hardness and mechanical property were reduced obviously, so that they fractured when impacted. No welding process with continuous weld but spot welding or other bonding method may be employed for the reason that the capacity of the 22MnB5 steel plate in the weld heat-affected zone was reduced obvi- ously.

    Comfort on automobile seats is lived daily by thousands of drivers. Epistemologically, comfort can be understood under the theory of complexity, since it emerges from a chain of interrelationships between man and several elements of the system. This interaction process can engender extreme comfort associated to the feeling of pleasure and wellbeing or, on the other hand, lead to discomfort, normally followed by pain. This article has for purpose the development of a theoretical model that favours the comfort feature on automobile seats through the identification of its facets and indicators. For such, a theoretical study is resorted to, allowing the mapping of elements that constitute the model. The results present a comfort model on automobile seats that contemplates the (physical, psychological, object, context and environment) facets. This model is expected to contribute with the automobile industry for the development of improvements of the ergonomic project of seats to increase the comfort noticed by the users.

    A compilation of the physical properties of materials which might typically occur in automobile shredder residue and an analysis of their suitability for the separation of materials in fine (glass/stones) and organics (plastics). Results presented of laboratory scale tests demonstrate that fhf-ASR can in large part be separated into three principal components. Tests were conducted with 0.63-2.0mm and 2-10mm fractions. Recovery of plastics by density separations were conducted with water only jigs for the 2-10mm fraction and shaker tables for the 0.63-2mm fraction. Comparisons are presented of the separations of glass and stones from metals obtained by linear screening and vibratory screening of roller mill and impact mill crushing products of the high density 2-10mm fraction. Equipment used for these tests are of a laboratory or demonstrative scale. It is reasonable to anticipate that industrial scale processing would produce significantly better results. The 2-15mm fraction was found to constitute 91.6% of the fhf-ASR sampled. The metals content of the 2-10mm portion of this fraction was upgraded from 2.5% to 31% and 76.9% with recoveries varying inversely with grade from 91.9% to 40.1%. From 63.6% to 17.1% with a recovery of 93.5% of the organic materials. A residual product of fine sand of crushed glass/stones of 99.4% purity recovered 71.3% of these. PMID:26119010

  3. Is refinancing solely motivated by misappropriation?

    Chun Liu; Liang Sun

    2012-01-01

    Misappropriation has become the accepted explanation for the refinancing behavior of Chinese listed companies, although the evidence in support of such an explanation is worthy of further discussion. We argue that if a planned refinancing exercise does not become a reality, post-refinancing performance depends on the initial motivation for refinancing, i.e. misappropriation or the maximization of firm value. The success and failure samples provided by the approval system of the Chinese securities market provide us with a natural laboratory in which to distinguish between these two possible motivations for the refinancing behavior of Chinese listed firms. The results show the postrefinancing performance of firms in the success sample to be significantly better than the performance in the failure sample, with the difference even more significant when larger agency costs or more financial constraints exist. These findings indicate that Chinese listed companies do not engage in refinancing for misappropriation purposes alone. Rather, refinancing is more likely to be a rational choice made in full consideration of the costs and benefits. This paper provides new ideas for reexamining the motivations for the refinancing behavior of China’s listed firms. It also has one major policy implication. That is, relaxing and/or simplifying the country’s refinancing regulations could help to improve the efficiency of resource allocation in the Chinese securities market.

    We perform an experiment of achromatic imaging with wavefront coding (WFC) using a wide-angle automobile lens. Our original annular phase mask for WFC was inserted to the lens, for which the difference between the focal positions at 400 nm and at 950 nm is 0.10 mm. We acquired images of objects using a WFC camera with this lens under the conditions of visible and infrared light. As a result, the effect of the removal of the chromatic aberration of the WFC system was successfully determined. Moreover, we fabricated a demonstration set assuming the use of a night vision camera in an automobile and showed the effect of the WFC system.

    2002-07-01

    Platinum concentrations in topsoil samples collected in 1992 (48) and in 2001 (16) from the urban area of Rome have been determined by ICP-MS. Concentrations in 47 soil samples collected in 1992 from natural sites of Latium (an area around Rome) have been determined for a first assessment of natural background levels. The Pt concentrations in Rome urban soils collected in 1992 range from 0.8 to 6.3 ng/g (mean = 3.8 +/- 1.0) overlapping the concentration range of natural soils from Latium (mean = 3.1 +/- 2.1 ng/g). No significant correlation has generally been found between Pt contents in the 'natural' soils and related bedrock or major pedogenetic parameters. These results suggest that there is no evidence of Pt pollution in Rome urban soils at that time, because the massive use of the automobile catalytic converter has only just started. Higher (up to six times more) Pt concentrations, than those measured in the 1992 samples, have been measured, in some cases, in Rome urban soils collected in 2001, suggesting a possible start of Pt accumulation because of the large-scale use in the last decade of automobile catalytic converters. At the same time, a clear decrease of lead levels in Rome urban soils with respect to the levels measured in 1992 has been observed, paralleling the decreasing number of lead gasoline-fuelled cars. Here we present one of the first systematic studies for defining background levels of Pt in Italian natural soils, thus allowing for monitoring, in the future, should any possible Pt pollution caused by the use of automobile catalytic converter, especially in urban soils, occur.

    Mir, L.; Simard, C.; Grana, D.

    1973-01-01

    Ferrofluids are colloidal dispersions of subdomain magnetic solids in carrier liquids. In the presence of a non-homogeneous magnetic field, ferrofluids exert a pressure on immersed nonmagnetic objects in the opposite sense of the field gradient. This pressure force can, when opposite to gravity, levitate objects of higher density than the ferrofluid. This levitation technique can be used to separate solids according to density. Its application to the separation of nonferrous metals from shredded automobiles has been demonstrated on a prototype of a full-scale separator. Its use to recover nonferrous metals from municipal solid wastes also seems practical.

    Speed- and distance control by automobile-drivers is described best by linear models when the leading vehicles speed varies randomly and when the driver is motivated to keep a large distance. A car-following experiment required subjects to follow at 'safe' or at 'close' distance. Transfer-characteristics of the driver were extended by 1 octave when following 'closely'. Nonlinear properties of drivers control-movements are assumed to reflect different motivation-dependent control strategies.

    Sex hormones have been reported to dynamically modulate the expression of implicit motives, a concept that has previously been thought to be relatively stable over time. This study investigates to what extent the need for affiliation, power, and achievement, as well as the form of enactment of these needs as measured with the Operant Motive Test (OMT), is affected by cycle-phase dependent sex hormone fluctuations. In addition to measuring the strength of motive expression, the OMT also captures different forms of motive enactment. In an intra-subject design with repeated measures, no evidence for cycle-phase related variation in overall motive scores was found. However, when different forms of motive enactment were considered, an effect of menstrual cycle was observed. The incentive-based inhibition of the power motive was significantly reduced at the time of ovulation, compared to the menstrual and to the mid-luteal phase, in naturally cycling women. In women with relatively stable hormone concentrations (due to using hormonal contraceptives), no significant changes in the form of motive enactment were evident.

    Full Text Available Possessing social power has psychological and biological benefits. For example, during task interactions, people high in power are more likely to display a benign cardiovascular response pattern indicative of challenge whereas people low in power are more likely to display a maladaptive cardiovascular pattern indicative of threat (Scheepers, De Wit, Ellemers, & Sassenberg, 2012. Challenge is marked by high cardiac output (CO and low total peripheral resistance, while threat is marked by low CO and high TPR (Blascovich & Mendes, 2010. In the current work we addressed a possible moderator of the power-threat/challenge relationship, namely the stability of power. We examined the influence of the stability of power (roles could or could not change on cardiovascular responses during a dyadic task where one person was the chief designer (high power and one person was the assistant (low power. During the task, different cardiovascular-measures were taken (CO, TPR, Heart Rate [HR], Pre-Ejection Period [PEP]. Whereas participants in the unstable low power condition showed a stronger tendency towards challenge, participants in the unstable high power condition showed a stronger tendency towards threat. Moreover, participants in the stable low power condition showed cardiovascular signs of task disengagement. Results are discussed in terms of the importance of contextual variables in shaping the relationship between power and benign/maladaptive physiological responses.

  20. The automobile share

    International Nuclear Information System (INIS)

    Out of a conversion of 120 billions metric tons of fossil carbon per year 1 billion are traffic related. But this amount is growing steadily. The global automobile density is about 10 automobiles per capita. It grows with 1.7% per year, as fast as the population. The number of automobiles doubles in 25 years. In all groups of developed countries the automobile density increased from 5 to 50 automobiles per capita in less than 50 years so far. Where is the fuel for the 1 billion automobiles of the year 2030 or 2050? Can one reduce this number or what chances does one have to reduce the adverse consequences? Whatever the number of motor vehicles will be, man will have the chance to reduce fuel consumption and therefore CO2-emission together with other emissions considerably

    The car, and the range of social and political institutions which sustain its dominance, play an important role in many of the environmental problems faced by contemporary society. But in order to understand the possibilities for moving towards sustainability and 'greening cars', it is first necessary to understand the political forces that have made cars so dominant. This book identifies these forces as a combination of political economy and cultural politics. From the early twentieth century, the car became central to the organization of capitalism and deeply embedded in individual identities, providing people with a source of value and meaning but in a way which was broadly consistent with social imperatives for mobility. Projects for sustainability to reduce the environmental impacts of cars are therefore constrained by these forces but must deal with them in order to shape and achieve their goals. Addresses the increasingly controversial debate on the place of the car in contemporary society and its contribution to environmental problems Questions whether automobility is sustainable and what political, social and economic forces might prevent this Will appeal to scholars and advanced students from a wide range of disciplines including environmental politics, political economy, environmental studies, cultural studies and geography

    Passenger cars in the United States (U.S.) rely primarily on petroleum-derived fuels and contribute the majority of U.S. transportation-related greenhouse gas (GHG) emissions. Electricity and biofuels are two promising alternatives for reducing both the carbon intensity of automotive transportation and U.S. reliance on imported oil. However, as standalone solutions, the biofuels option is limited by land availability and the electricity option is limited by market adoption rates and technical challenges. This paper explores potential GHG emissions reductions attainable in the United States through 2050 with a county-level scenario analysis that combines ambitious plug-in hybrid electric vehicle (PHEV) adoption rates with scale-up of cellulosic ethanol production. With PHEVs achieving a 58% share of the passenger car fleet by 2050, phasing out most corn ethanol and limiting cellulosic ethanol feedstocks to sustainably produced crop residues and dedicated crops, we project that the United States could supply the liquid fuels needed for the automobile fleet with an average blend of 80% ethanol (by volume) and 20% gasoline. If electricity for PHEV charging could be supplied by a combination of renewables and natural-gas combined-cycle power plants, the carbon intensity of automotive transport would be 79 g CO2e per vehicle-kilometer traveled, a 71% reduction relative to 2013.

    The current study aimed to (a) evaluate the effectiveness of motivational interviewing, as applied by a community mental health team (CMHT) based in Singapore; (b) reduce hospital admissions and length of hospital stay; and (c) improve global functioning and satisfaction of individuals with mental illness. The current study used a quasi-experimental method. A convenience sample of 120 participants was selected from the caseload of the CMHT. Participants received motivational interviewing sessions at least once every month for 1 year. Data on the number of hospital admissions, length of hospitalization, Global Assessment of Functioning, and patient satisfaction were collected at baseline and 6 and 12 months. Participants who underwent the CMHT services with motivational interviewing were more compliant to treatment, resulting in significant reduction in hospitalization and improvement in functionality. Motivational interviewing is effective in facilitating better illness management for patients in the community. Adoption of the motivational interviewing approach may potentially provide significant benefits for psychiatric support services in the community.

    Shimada, Yuhki; Ohe, Jun-ichiro

    2015-05-01

    The spin motive force driven by the dynamics of the skyrmion structure formed in a nanomagnetic disk is numerically investigated. Due to the existence of the magnetic structure along the disk edge, the collective mode of the magnetization is modified from that of the bulk skyrmion lattice obtained by using the periodic boundary condition. For a single-skyrmion disk, the dynamics of the skyrmion core and the edge magnetization induce the spin motive force, and a measurable AC voltage is obtained by two probes on the disk. For a multi-skyrmions disk, the phase-locked collective mode of skyrmions is found in the lowest resonant frequency where the amplitude of the AC voltage is enhanced by the cascade effect of the spin motive force. We also investigate the effect of the Rashba spin-orbit coupling on the spin motive force.

    The lack of investment in the energy sector, allied to the seasoning of natural resources necessity for the generation of hydroelectric energy, makes the rationalization of the use of electric energy an indispensable tool for country growth in an harmonic manner. The animal feed can represent around 70 to 80% of the total cost for running an animal feed production facility. So, it is important to study the energy management in processes that mainly use motive power, such as the animal feed factories. In the animal feed factory studied, the electric motors are used mainly for milling and mixture granulated and transportation. The objective of this paper is to manage the use of electric energy, by matching motive power at the Pif Paf animal feed industry to the load needs. The average electric motors load index was 48.6%, indicating a likelihood of economy. The potential economy with electric energy using the best options of motive power was about R$ 24,426.50 per year (23.9%). To achieve this goal it is also necessary: to adjust relays and to choose fuses, to schedule operation and to build storage facilities. (author)

    1974-01-01

    The sensitivity of operating conditions upon performance of the modern steam automobile is discussed. The word modern has been used in the title to indicate that emphasis is upon miles per gallon rather than theoretical thermal efficiency. This has been accomplished by combining classical power analysis with the ideal Pressure-Volume diagram. Several parameters are derived which characterize performance capability of the modern steam car. The report illustrates that performance is dictated by the characteristics of the working medium, and the supply temperature. Performance is nearly independent of pressures above 800 psia. Analysis techniques were developed specifically for reciprocating steam engines suitable for automotive application. Specific performance charts have been constructed on the basis of water as a working medium. The conclusions and data interpretation are therefore limited within this scope.

    In the present study we examined the moderating effect of the power motive on salivary cortisol responses to acute psychosocial stress and exercise in adolescents. Fifty-seven high school students aged M = 14.8 years participated in the study. The Operant Motive Test was applied to measure the implicit power motive and the Personality Research Form was used to measure the explicit power motive. Salivary cortisol levels were assessed before and after the stress stimuli. Participants were randomly assigned to three experimental groups. An exercise group ran 15 minutes at a defined heart rate of 65-75% HRmax. A psychosocial stress group worked on a standard intelligence test for the same amount of time under the assumption, that their test scores will be made public in class after the test. The control group participated in a regular class session. The implicit power motive was significantly associated with increased cortisol levels in the psychosocial stress group. The explicit power motive was not associated with cortisol responses. Findings suggest that the implicit power motive moderates the cortisol responses to acute stress in an adolescent age group with higher responses to psychosocial stress in comparison to exercise or control conditions.

  9. The motivation behind serial sexual homicide: is it sex, power, and control, or anger?

    Myers, Wade C; Husted, David S; Safarik, Mark E; O'Toole, Mary Ellen

    2006-07-01

    Controversy exists in the literature and society regarding what motivates serial sexual killers to commit their crimes. Hypotheses range from the seeking of sexual gratification to the achievement of power and control to the expression of anger. The authors provide theoretical, empirical, evolutionary, and physiological support for the argument that serial sexual murderers above all commit their crimes in pursuit of sadistic pleasure. The seeking of power and control over victims is believed to serve the two secondary purposes of heightening sexual arousal and ensuring victim presence for the crime. Anger is not considered a key component of these offenders' motivation due to its inhibitory physiological effect on sexual functioning. On the contrary, criminal investigations into serial sexual killings consistently reveal erotically charged crimes, with sexual motivation expressed either overtly or symbolically. Although anger may be correlated with serial sexual homicide offenders, as it is with criminal offenders in general, it is not causative. The authors further believe serial sexual murderers should be considered sex offenders. A significant proportion of them appear to have paraphilic disorders within the spectrum of sexual sadism. "sexual sadism, homicidal type" is proposed as a diagnostic subtype of sexual sadism applicable to many of these offenders, and a suggested modification of DSM criteria is presented.

    The combination of plasma discharge and TiO2 photocatalysis exhibits high performances in the removal of nitrogen monoxide (NO). This article is aimed at elucidating the relationships between NO decomposition efficiency and various experimental parameters, including voltages, humidity and temperature. The experimental results indicate that the efficiency of NO removal by synergic plasma-catalyst coupling is significantly higher than plasma only or photocatalyst only systems. Moreover, the NO removal efficiency improves with the increase of applied voltage. Meanwhile, a higher humidity results in a reduced number of electron-hole pairs at the surface of TiO2 photocatalyst, leading to lower synergic purification efficiencies. Finally, the efficiency of NO removal is raised with the increase of temperature due to the fact that the adsorption of NO and water by nano-TiO2 is affected by environmental temperature.

  17. Réduction de la pollution atmosphérique due à l'automobile et économie d'énergie Reducing Air Pollution Caused by Automobiles and Energy Conservations

    Directory of Open Access Journals (Sweden)

    Salé B.

    2006-11-01

    Full Text Available L'action engagée dans les pays industriels pour réduire la pollution atmosphérique doit maintenant tenir compte, plus encore que par le passé, de la nécessité, imposée par la conjoncture, d'économiser l'énergie. L'article est consacré à l'étude de la compatibilité de ces deux objectifs en ce qui concerne l'automobile. L'ensemble des actions antigaspillage ou antipollution ne portant pas sur le générateur d'énergie constitue un domaine de compatibilité évident. En revanche la réduction des émissions de polluants nécessite des modifications plus ou moins profondes du moteur dont certaines peuvent poser des problèmes du point de vue de l'économie d'énergie. Dans le but de préciser la nature de ces problèmes, les techniques antipollution correspondant à différents niveaux de limitation des émissions sont examinées du point de vue de leur coût, de leur incidence sur la consommation de carburant et de leur interaction avec les procédés visant à l'économie d'énergie. Sont ainsi passés en revue les moyens de réduction des émissions basés sur une amélioration de la combustion, les procédés de post-combustion, le problème de la réduction de la teneur en plomb des essences. Cette analyse montre que dans une large mesure la réduction des émissions de polluants et la diminution de la consommation sont des objectifs compatibles, mais que la difficulté des problèmes à résoudre pour que les mesures antipollution n'aient pas d'effet négatif au plan de l'économie d'énergie croît très rapidement avec la sévérité de ces mesures au-delà d'un certain niveau. L'effort de recherche entrepris dans le monde sur ce thème devrait progressivement permettre à la fois de réduire encore de façon substantielle les émissions de polluants et d'améliorer le rendement des moteurs. Efforts made by industrialized countries ta reduce air pollution must now, more than ever, give consideration to the need for energy

    Full Text Available This paper presented a study on proposing a method for motivation with the use of QFD. It was reported by three students who majored in MOT at Graduate School of Science and Engineering, Yamagata University in 2009. QFD has been widely used in manufacture and service industries for making improvement with the existing products and programs. However, in this study, QFD was not used in the sense of “activation” to improve motivation. Rather, it took the viewpoint of “what is required by customers”, the central theme QFD, to approach the problem. With reference to the process of knowledge conversion suggested by the SECI Model, the study operated with the basic principles and steps of QFD. In the paper, the major steps of QFD leading to setting quality planning were outlined and the implication of the study was discussed.

    Due to the refrigerant gas R134a which is used in automobile air conditioning systems and has greater global warming impact will be phased out gradually, an alternative gas is being desired to be used without much change on existing air conditioning systems. It is aimed to obtain the easier solution for intermediate values on the performance by creating a Neural Network Model in case of using a fluid (R152a) in automobile air conditioning systems that has the thermodynamic properties close to each other and near-zero global warming impact. In this instance, a network structure giving the most accurate result has been established by identifying which model provides the best education with which network structure and makes the most accurate predictions in the light of the data obtained after five different ANN models was trained with three different network structures. During training of Artificial Neural Network, Quick Propagation, Quasi-Newton, Levenberg-Marquardt and Conjugate Gradient Descent Batch Back Propagation methodsincluding five inputs and one output were trained with various network structures. Over 1500 iterations have been evaluated and the most appropriate model was identified by determining minimum error rates. The accuracy of the determined ANN model was revealed by comparing with estimates made by the Multi-Regression method.

    2001-01-01

    Following the introduction of automobile catalysts in the middle of the 1980s in Germany there is an increasing emission of the platinum-group-metals platinum, palladium (Pd) and rhodium. Still, it remains unclear if these metals are bioavailable for aquatic animals and to which extent they become accumulated by the aquatic biosphere. Because of analytical problems in detecting Pd in small biological samples the present investigation concentrates on the bioavailability of this metal. To answer the question of a Pd uptake by aquatic organisms experimental studies were conducted with European eels maintained in water containing road dust at a concentration of 10 kg/100 l. Following an exposure period of four weeks, samples of liver and kidney were analysed by total-reflection X-ray fluorescence analysis after co-precipitation of Pd with mercury. These experiments revealed an uptake of traffic related Pd by European eels which showed a mean liver Pd concentration of 0.18 +/- 0.05 ng/g (wet wt.), whereas the Pd concentration in the kidney ranged below the detection limit. Thus, in this study we can demonstrate for the first time that automobile catalyst emitted Pd is bioavailable for aquatic animals. PMID:11428142

By contrast, an “EV society” is a concept whereby EVs are more fundamentally woven into the fabric of society with the aim of solving a range of social problems, while at the same time questioning the meaning of what an automobile “is” and “can be.” It is this “game-changing” principle of integration that drives our research.

    2016-01-01

    A well worked-out motivational system in laboratory animals produces estrogen-dependent female sex behavior. Here, we review (a) the logical definition of sexual motivation and (b) the basic neuronal and molecular mechanisms that allow the behavior to occur. Importantly, reproductive mechanisms in the female can be inhibited by stress. This is interesting because, in terms of the specificity of neuroendocrine dynamics in space and time, the two families of phenomena, sex and stress, are the opposite of each other. We cover papers that document stress effects on the underlying processes of reproductive endocrinology in the female. Not all of the mechanisms for such inhibition have been clearly laid out. Finally, as a current topic of investigation, this system offers several avenues for new investigation which we briefly characterize. PMID:26650839

  8. Wind power implementation: The nature of public attitudes: Equity and fairness instead of 'backyard motives'

    Energy Technology Data Exchange (ETDEWEB)

    Wolsink, Maarten

    2007-08-15

    Public attitudes anywhere in Europe show moderate to strong support for the implementation of renewable energy. Nevertheless, planning wind power developments appears to be a complicated matter in most countries. The problems that have to be dealt with during decision making processes on the siting of wind turbines are usually referred to as mere 'communication problems'. However, public attitudes towards wind power are fundamentally different from attitudes towards wind farms. This 'gap' causes misunderstandings about the nature of public support for renewables. In particular where planners easily assume support for renewables can be generated by information campaigns emphasising the environmental benefits, whereas opposition to renewable energy schemes can be explained by a selfish 'not in my backyard' attitude. Both explanations used by planners, authorities and, unfortunately, by many scholars, are falsified. Furthermore, policies that still take this 'common knowledge' for granted can have negative consequences for the implementation rates of renewables. Visual evaluation of the impact of wind power on landscape values is by far the dominant factor in explaining why some are opposed to wind power and others are supporting it. Moreover, feelings about equity and fairness appear the determinants of 'backyard' motives, instead of selfishness. (author)

    The uptake and bioaccumulation of the platinum group metals (PGM) platinum (Pt), palladium (Pd), and rhodium (Rh) by the zebra mussel (Dreissena polymorpha) were investigated in exposure studies using ground material from unused automobile catalytic converters as metal source. The mussels were exposed to the metals in tap water or humic water. In the soft tissue samples of exposed mussels mean Pt levels ranged in dependence on the type of tank water and the exposure period (6, 9, or 18 weeks) between 780 and 4300 ng/g, the Pd levels ranged between 720 and 6300 ng/g, and the Rh levels ranged between 270 and 1900 ng/g. In contrast, the control mussels had metal concentrations of <20 ng/g (Pt), <50 ng/g (Pd), and <40 ng/g (Rh). Considerably higher PGM levels were found in the exposed mussels of the humic water group than in those of the tap water group. Although there is a cumulative increase of the PGM concentrations in the environment since the introduction of the automobile catalyst more than 20 years ago, only little information about the PGM contamination in the biosphere, especially the fauna, is available. Due to the high capacity of D. polymorpha to accumulate PGM, this bivalve could be used as a potential sentinel for monitoring the noble metals in aquatic ecosystems. PMID:15820726

    This talk discusses the technical options available for automobiles within the next 5 to 10 years. With the objective to reduce consumption and pollution, several alternative approaches are presented and analyzed using simplified but realistic calculations. Main emphasis is laid on CO{sub 2} emission of the complete energy transformation path from the primary energy carrier to the energy dissipated in test cycles. It is shown that no single optimal solution exist but that a trade-off between consumption, pollution and cost must be made for each specific situation. (author) 17 figs., 2 tabs.

  13. Power spectrum oscillations from Planck-suppressed operators in effective field theory motivated monodromy inflation

    Science.gov (United States)

    Price, Layne C.

    2015-11-01

    We consider a phenomenological model of inflation where the inflaton is the phase of a complex scalar field Φ . Planck-suppressed operators of O (f5/Mpl) modify the geometry of the vev ⟨Φ ⟩ at first order in the decay constant f , which adds a first-order periodic term to the definition of the canonically normalized inflaton ϕ . This correction to the inflaton induces a fixed number of extra oscillatory terms in the potential V ˜θp. We derive the same result in a toy scenario where the vacuum ⟨Φ ⟩ is an ellipse with an arbitrarily large eccentricity. These extra oscillations change the form of the power spectrum as a function of scale k and provide a possible mechanism for differentiating effective field theory motivated inflation from models where the angular shift symmetry is a gauge symmetry.

    The laudable effort by Strayer and his colleagues to derive a systematic method to assess forms of cognitive distraction in the automobile is beset by the problem of nonstationary in driver response capacity. At the level of the overall goal of driving, this problem conflates actual on-road behavior; characterized by underspecified task satisficing, with our own understandable, scientifically inspired aspiration for measuring deterministic performance optimization. Measures of response conceived under this latter imperative are, at best, only shadowy reflections of the actual phenomenological experience involved in real-world vehicle control. Whether we, as a research community, can resolve this issue remains uncertain. However, we believe we can mount a positive attack on what is arguably another equally important dimension of the collision problem.

    Monitoring of PGEs content in the natural samples is a crucial point in the environment science since catalytic car converters have been introduced. In the presented paper application of a very sensitive voltammetric method for determination of traces of Pt and Rh in the environmental samples contaminated by automobile exhausts is discussed. Voltammetric measurements were carried out in the supporting electrolyte containing formaldehyde and semicarbazide. PGEs were separated from the digested solutions of soils or quartz samples, collected from monitoring plots-by applying an ion-exchange resin Cellex-T. Pt was very effectively separated from the matrix approaching nearly 100% recovery after its elution by hydrochloric acid. Moreover the conditions of soil and quartz samples digestion were discussed. To validate the obtained result an independent analytical method-ICP MS was applied and analysis of certified reference material road dust 723-was completed.

    Correlations between a job performance criterion and personality measures reflecting achievement motivation and an interpersonal orientation were examined at three points in time after completion of job training for a sample of airline reservations agents. Although correlations between the personality predictors and performance were small and nonsignificant for the 3-month period after beginning the job, by the end of six and eight months a number of significant relationships had emerged. Implications for the utility of personality measures in selection and performance prediction are discussed.

  3. Consumer preferences for automobile energy-efficiency grades

    International Nuclear Information System (INIS)

    Recently, increases in energy prices have made energy conservation and efficiency improvements even more essential than in the past. However, consumers experience difficulty in obtaining reliable information regarding energy efficiency, so that many countries have implemented regulations to enforce energy-efficiency grade labeling. In this study, consumer preferences regarding energy efficiency grades are analyzed by the mixed logit and MDCEV model based on the revealed preference data of past automobile purchases. Findings show that consumers rationally apply information on energy efficiency grades when purchasing automobiles. However, they tend to show inefficiency in automobile usage patterns. This study discusses political implications of energy efficiency policies as they might impact consumer behaviors of automobile purchase and usage. - Highlights: ► We model discrete choice model to evaluate energy-efficiency grade regulation. ► Consumers apply information on energy efficiency grades when purchasing automobiles. ► However, they tend to show inefficiency in automobile usage patterns. ► The policies for efficient automobile usage are discussed.

    Full Text Available Investment volume is considered as an important factor in regional development under current conditions. Logistical infrastructure which ensures a complex transport, distributive, information and other services exerts a significant influence on regional investment attractiveness. Lack of clear vision on development and execution of development strategy for logistics infrastructure from the side of regional authorities results in unwillingness of large federal and transnational companies to provide investments in infrastructure projects. Network of automotive transport terminals is one of the main elements in logistics infrastructure. The network allows to optimize a flow of material goods from the point of their origin to the point of their consumption with the lowest possible costs and the required level of service. Automobile transport is one of the main objects of transport infrastructure and it is characterized by rather high flexibility in comparison with other types of transport facilities that preconditions its widespread application. Network of automobile fleets (terminals has been formed for redistribution of goods traffic within the concerned regions. The purpose of the present research is to develop a mathematical model for formation of transport infrastructure on the territory of regions. The paper proposes an approach for formation of automobile fleet (terminal network on the territory of a large region with due account of the established network of distribution and sorting-out warehouse facilities. A model has been developed for solving the problem pertaining to minimization of aggregate costs related to maintenance of automobile fleets, delivery of goods to and from distribution and sorting-out warehouse facilities to consumers, ferry of empty trucks and goods handling.

  6. Ready for nuclear energy?: An assessment of capacities and motivations for launching new national nuclear power programs

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency reports that as of July 2009 there were 52 countries interested in building their first nuclear power plant. This paper characterizes and evaluates these 'Newcomer Countries' in terms of their capacity and motivations to develop nuclear power. It quantifies factors historically associated with the development of nuclear energy programs and then benchmarks the Newcomers against these data. Countries with established nuclear power programs, particularly where nuclear facilities are privately owned, are typically larger, wealthier and politically stable economies with high government effectiveness. Nuclear power was historically launched during periods of high electricity consumption growth. Other indicators for the potential of nuclear power include: the size of the national grid, the presence of international grid connections and security of fuel supply for electricity production. We identify 10 Newcomers which most closely resemble the Established Nuclear Power Countries and thus are most likely to deploy nuclear energy, 10 countries where the development of nuclear energy is uncertain due to high political instability, 14 countries with lower capacities where pursuing nuclear energy may require especially strong international cooperation and 18 countries where the development of nuclear power is less likely due to their significantly lower capacities and motivations. - Research Highlights: →Historically, nuclear power was used in larger, wealthier, politically stable economies. →Nuclear power was typically launched in periods of high electricity demand growth. →Only 10 out of 52 'Newcomer' countries share similar characteristics. →10 other 'Newcomers' with high motivations and capacities are politically unstable. →Nuclear power would need international help in 14 countries and is unlikely in the rest (18).

    Full Text Available States and international organizations have compiled lists of a great variety of terrorist groups. The current European Union list includes 44 entities. This study analyzes the underlying motives of the terrorist organizations named in this list. In order to understand the groups’ motivations and consequently be able to advise on methods of countering them with communication strategies, we employ a three-item typology provided by Waldmann (2001. The results show that only five of the 44 groups were religiously motivated to commit terrorism. Most of the groups (n=20 had nationalist-separatist motives, and 19 groups displayed social-revolutionary motives. Based on the respective motives, differing counter-terrorism strategies are proposed, e.g., developing rhetorical counter-narratives that address and reduce the groups’ motivational and identity-generating characteristics.

    Full Text Available A novel method which is a combination of wavelet packet transform (WPT, uninformative variable elimination by partial least squares (UVE-PLS and simulated annealing (SA to extract best variance information among different varieties of lubricants is presented. A total of 180 samples (60 for each variety were characterized on the basis of visible and short-wave infrared spectroscopy (VIS-SWNIR, and 90 samples (30 for each variety were randomly selected for the calibration set, whereas, the remaining 90 samples (30 for each variety were used for the validation set. The spectral data was split into different frequency bands by WPT, and different frequency bands were obtained. SA was employed to look for the best variance band (BVB among different varieties of lubricants. In order to improve prediction precision further, BVB was processed by UVE-PLS and the optimal cutoff threshold of UVE was found by SA. Finally, five variables were mined, and were set as inputs for a least square-support vector machine (LS-SVM to build the recognition model. An optimal model with a correlation coefficient (R of 0.9850 and root mean square error of prediction (RMSEP of 0.0827 was obtained. The overall results indicated that the method of combining WPT, UVE-PLS and SA was a powerful way to select diagnostic information for discrimination among different varieties of lubricating oil, furthermore, a more parsimonious and efficient LS-SVM model could be obtained.

  1. A mathematic model of thermoelectric module with applications on waste heat recovery from automobile engine

    International Nuclear Information System (INIS)

    Over two-thirds energy of fuel consumed by an automobile is discharged to the surroundings as waste heat. The fuel usage can be more efficient if thermoelectric generators (TEG) are used to convert heat energy into electricity. In this study, a thermoelectric module composed of thermoelectric generators and a cooling system is developed to improve the efficiency of an IC engine. Two potential positions on an automobile are chosen to apply this module, e.g. exhaust pipe and radiator to examine the feasibility. To predict the behaviors of this module, a one dimensional thermal resistance model is also build, and the results are verified with experiments. The maximum power produced from the module is 51.13 mWcm-2 at 290 oC temperature difference. The model results show that, TE module presents better performance on the exhaust pipe than on the radiator.

    2016-10-01

    Adaptive motivated behavior requires predictive internal representations of the environment, and surprising events are indications for encoding new representations of the environment. The medial temporal lobe memory system, including the hippocampus and surrounding cortex, encodes surprising events and is influenced by motivational state. Because behavior reflects the goals of an individual, we investigated whether motivational valence (i.e., pursuing rewards versus avoiding punishments) also impacts neural and mnemonic encoding of surprising events. During functional magnetic resonance imaging (fMRI), participants encountered perceptually unexpected events either during the pursuit of rewards or avoidance of punishments. Despite similar levels of motivation across groups, reward and punishment facilitated the processing of surprising events in different medial temporal lobe regions. Whereas during reward motivation, perceptual surprises enhanced activation in the hippocampus, during punishment motivation surprises instead enhanced activation in parahippocampal cortex. Further, we found that reward motivation facilitated hippocampal coupling with ventromedial PFC, whereas punishment motivation facilitated parahippocampal cortical coupling with orbitofrontal cortex. Behaviorally, post-scan testing revealed that reward, but not punishment, motivation resulted in greater memory selectivity for surprising events encountered during goal pursuit. Together these findings demonstrate that neuromodulatory systems engaged by anticipation of reward and punishment target separate components of the medial temporal lobe, modulating medial temporal lobe sensitivity and connectivity. Thus, reward and punishment motivation yield distinct neural contexts for learning, with distinct consequences for how surprises are incorporated into predictive mnemonic models of the environment.

    2007-01-01

    Aiming at developing exhaust gas driving automobile air conditioning systems, a hydride pair LaNi4.61Mn0.26A10.13/La0.6Y0.4Ni4.8Mn0.2 was developed working at 393~473 K/293~323 K/263~273 K. Property tests showed that both alloys have flat plateau slopes and small hystereses; system theoretical coefficient of performance (COP) is 0.711. Based on this work pair, a function proving automobile metal hydride refrigeration system was constructed. The equivalent thermal conductivities of the activated reaction beds were merely 1.1~1.6 W/(m·K), which had not met practical requirement. Intermittent refrigeration cycles were achieved and the average cooling power was 84.6 W at 423 K/303 K/273 K with COP being 0.26. By altering cycling parameters, experiment data showed that cooling power and system COP increase with the growth of heat source temperature as well as pre-heating and regeneration time while decrease with heat sink temperature increment. This study confirms the feasibility of automobile metal hydride refrigeration systems, while heat transfer properties of reaction beds still need to be improved for better performance.

    Full Text Available Abstract The aim of this study was to test the predictive power of dispositional orientations, general self-efficacy and self-determined motivation on fun and boredom in physical education classes, with a sample of 459 adolescents between 13 and 18 with a mean age of 15 years (SD = 0.88. The adolescents responded to four Likert scales: Perceptions of Success Questionnaire, General Self-Efficacy Scale, Sport Motivation Scale and Intrinsic Satisfaction Questionnaire in Sport. The results showed the structural regression model showed that task orientation and general self-efficacy positively predicted self-determined motivation and this in turn positively predicted more fun and less boredom in physical education classes. Consequently, the promotion of an educational task-oriented environment where learners perceive their progress and make them feel more competent, will allow them to overcome the intrinsically motivated tasks, and therefore they will have more fun. Pedagogical implications for less boredom and more fun in physical education classes are discussed.

    In situ deposition of silver particles onto alumina and palladium particles onto mixed CeZr oxides has been achieved upon chemical reduction of the corresponding metal species (AgNO 3 and PdCl 2) by ethylene glycol in the presence of polyvinylpyrrolidone. The support oxide powders were found to keep their crystalline structure and morphology after treatment with hot ethylene glycol while the BET surface area decreased after metal deposition. Microprobe maps obtained from energy dispersive X-ray analysis revealed a homogeneous distribution of metal nanoparticles on the surfaces of alumina and of the mixed CeZr oxides. Supported silver and palladium were tested as catalytic converters of simulated exhaust automobile gases. The catalytic activity of silver-loaded alumina powder catalyst for CO and hydrocarbon oxidation as well as NO and NO x reduction, was found to be higher than that of a reference silver catalyst. Palladium-loaded mixed CeZr oxides powder catalyst showed a similar performance to that of a reference palladium catalyst as a three-way catalyst converter.

    Production of driving force is the main factor effecting the energy consumption of an automobile and often also of the entire transportation, as well as the main cause of environmental impacts of transportation. The most significant environmental hazard of the transportation is the formation of emissions polluting the air. Recent development of catalysts and other flue gas purification technology has eased significantly the control of flue gas emissions. New solutions have been developed for NO{sub x} emissions of diesel engines, e.g. the zeolite catalysts, which reduce them also in oxygen-rich flue gases. Particulates form still a significant problem. Continuous tightening of emission restrictions has made the flue gas purification systems more complex and expensive than before. Reduction of energy consumption by developing the engine technology is difficult when the flue gas purity requirements are continuously tightened. More interest is paid to new alternatives, the energy balance of that is better, because the main concern in emission reduction is in control of CO{sub 2}, not in reduction of poisonous emissions. This leads to a reduction of the greenhouse effects of transportation. There are no practical chemical or physical recovery or purification methods for reduction of CO{sub 2} emissions. It is essential to study the means, by which the fuel consumption and the efficiency of engines could be improved. It is possible to reduce the greenhouse gas emissions by using alternative fuels, totally new power sources and more effective energy chains. Rolling and air resistances are the main factors consuming energy. When the driving speed doubles the air resistance quadruples, so the driving speed of road traffic effects strongly on the energy consumption of an automobile. The weight of a vehicle effects on fuel consumption especially in urban transport because of the repeated accelerations and decelerations. The efficiency of a Diesel engine is about 20% higher

    Holroyd, Clay B; Yeung, Nick

    2012-02-01

    Intense research interest over the past decade has yielded diverse and often discrepant theories about the function of anterior cingulate cortex (ACC). In particular, a dichotomy has emerged between neuropsychological theories suggesting a primary role for ACC in motivating or 'energizing' behavior, and neuroimaging-inspired theories emphasizing its contribution to cognitive control and reinforcement learning. To reconcile these views, we propose that ACC supports the selection and maintenance of 'options' - extended, context-specific sequences of behavior directed toward particular goals - that are learned through a process of hierarchical reinforcement learning. This theory accounts for ACC activity in relation to learning and control while simultaneously explaining the effects of ACC damage as disrupting the motivational context supporting the production of goal-directed action sequences.

  14. Corrosion protection and finishing of automobiles

    International Nuclear Information System (INIS)

    finishing of automobiles is an important aspect. There have been considerable reductions of weight in automobiles by the use of composites components replacing heavy metallic components. Fenders previously based on metal have been replaced with plastic and painted with the same colour shade as of the metallic body, this has eps for proper adhesion of the paints on the plastic fender to avoid chipping off the paint form it. This paper discusses the necessary processes required for finishing of an automobile along with the corrosion protection measures. Automobiles contains a variety of engineering materials, engine main body fuel tanks connecting rods heat radiators and other mechanical parts are made from different types of engineering alloys having varying chemical compositions. Other parts like dashboard, front panel and other are made from composites. The main body made from cold roll ed steel having various contours 'c' it due to the different designs is the potential site for corrosion attack, The main body is exposed to the hostile environment through out its life period. An automobile is given a particular finish with a view to counter the hostile environments as they are not limited for plying in a limiting conditions and are taken to different weather conditions in one day thus facing severe stresses and strain. Thus it is essential that an automobile before rolling 'out of the assembly line should properly corrosion resistant and aesthetically pleasant also. Finishing for automobiles being very specialized, the main requirement being maximum durability with minimum numbers of coats baked, at the fastest possible schedule. High gloss and range of good eye catching colours being important to increase sales appeal. In the near past the car finishes were based on alkyd-amino resins baking materials and force drying lacquers, which have excellent appearance originally and maintain it on aging. The finishing system for the synthetic baking type may consist of

    development for the combinations. Overall, none of the alternatives emerges as a clear winner, lowering the externalities and improving sustainability, while considering technology issues and vehicle attributes. The majority of the alternatives are not likely to displace the baseline automobile. However, the attractiveness of the alternatives depends on the focus of future regulations, government priorities, and technology development. If long-term global sustainability is the principal concern, then improvements in fuel economy alone will not provide the level of reduction in impact required. A switch to renewable fuels (e.g., alcohols or diesel produced from biomass) to power the vehicles will likely be necessary. (Abstract shortened by UMI.)

    For a typical spark ignition engine approximately 40% of available thermal energy is lost as hot exhaust gas. To improve fuel economy, researchers are currently evaluating technology which exploits exhaust stream thermal power by use of thermoelectric generators (TEGs) that operate on the basis of the Seebeck effect. A 5% improvement in fuel economy, achieved by use of TEG output power, is a stated objective for light-duty trucks and personal automobiles. System modeling of thermoelectric (TE) components requires solution of coupled thermal and electric fluxes through the n and p-type semiconductor legs, given appropriate thermal boundary conditions at the junctions. Such applications have large thermal gradients along the semiconductor legs, and material properties are highly dependent on spatially varying temperature profiles. In this work, one-dimensional heat flux and temperature variations across thermoelectric legs were solved by using an iterative numerical approach to optimize both TE module and TEG designs. Design traits were investigated by assuming use of skutterudite as a thermoelectric material with potential for automotive applications in which exhaust gas and heat exchanger temperatures typically vary from 100°C to over 600°C. Dependence of leg efficiency, thermal fluxes and electric power generation on leg geometry, fill fractions, electric current, thermal boundary conditions, etc., were studied in detail. Optimum leg geometries were computed for a variety of automotive exhaust conditions.

    Full Text Available Maslow's theory is by far the most known theory of motivation, and the most common in the business and management practice. Herzberg's theory fits the observations and explains some aspects of human motivation left unexplained by Maslow. However, these theories have never been formalized on a strictly mathematical basis. The present article gives an outline of a mathematical model of theories of motivation proposed by Abraham Maslow and Frederick Herzberg. This model is built on a basis of special non-continuous functions. This description may be a good basis for HR software and may be useful for business and management.

  8. Improvement of Machine Translation Evaluation by Simple Linguistically Motivated Features

    2011-01-01

    Adopting the regression SVM framework, this paper proposes a linguistically motivated feature engineering strategy to develop an MT evaluation metric with a better correlation with human assessments. In contrast to current practices of "greedy" combination of all available features, six features are suggested according to the human intuition for translation quality. Then the contribution of linguistic features is examined and analyzed via a hill-climbing strategy. Experiments indicate that, compared to either the SVM-ranking model or the previous attempts on exhaustive linguistic features, the regression SVM model with six linguistic information based features generalizes across different datasets better, and augmenting these linguistic features with proper non-linguistic metrics can achieve additional improvements.

    The long-term strategy of the automotive industry is to minimize its CO{sub 2} emissions and to progressively abandon petroleum. Today, the diesel technology is the most efficient in terms of CO{sub 2} emissions and the hybrid technology will be the medium-term challenge with the development of biofuels and synthetic fuels from biomass. According to the author, there is no certitude that the hydrogen fuel cell will be tomorrows' automobile engine and the nuclear option would be necessary to produce huge quantities of hydrogen without CO{sub 2} emissions. The alternate strategies with interesting potentialities remain the electric-powered vehicle supplied with batteries or supplied with methanol fuel cells, methanol being obtained by biomass transformation.

    Directory of Open Access Journals (Sweden)

    Sujit Kumar Jha

    2013-06-01

    Full Text Available The muffler is the main part of the Automobile Exhaust System, consisting of fibrous and porous materials to absorb noise and vibrations. The exhaust gas mass coming from the engine can produce resonance, which may be the source of fatigue failure in the exhaust pipe due to the presence of continuous resonance. The modes on the muffler should be located away from the engine’s operating frequencies in order to minimise the resonance. The objective of this paper is to determine the frequencies that appear at the modes, which have the more adverse effect during the operation of the automobile. An impact test has been conducted by applying the force using a hard head hammer, and data generated have been used for plotting a graph of the transfer functions using MATLAB. Six points have been selected, namely 1, 2, 3, 4, 7, and 11 on the muffler for the impact test. The collected data from theses six points have been analysed for the addition of damping. Results suggests that increasing the mass increases the damping and lowers the modes of the transfer function. Further research will identify higher strength materials that can withstand the higher gas temperatures as well as the corrosion and erosion by the gas emitted from the engine.

    1979-01-01

    Although pharmacists are developing interest in many types of pharmacy practice, they are still spending the bulk of their time in the prescription dispensing process. Any effort to provide motivation must consider the prescription dispensing process. The pharmacy literature includes only a few studies that dealt with pharmacists as people. The studies usually showed that pharmacists basically were unhappy with their jobs. In developing a motivational climate for pharmacists, pharmacy supervisors have several concepts to consider: the hierarchy of needs by Maslow; the expectancy theory by Hampton; the gygiene-motivator theory by Herzberg; and the Theory Y management approach by McGregor. Because pharmacists must be induced to enter and remain in an organization, supervisors should be aware of the need to use any technique available in developing a motivational climate.

In US, citizens spend nearly 100 minutes in cars per day. There are safety problems in cars except than seatbelt and airbag. Some of these are seats, furnishing, cushions for arm and head, floor covering, accessories and plastic parts. In a study conducted in Japan, more than 160 volatile organic compounds (VOC had been determined in new cars and a three years old car. Some of the pollutants are formaldehyde, toluen, xylene, ethylbenzene and styrene. Also Polybrominated diphenyl ethers (PBDEs, which may be degradated by sunshine in hot seasons are measured within the outomobiles. There is a big gap of studies about the pollutants in cars and researches have to be conducted. Manufacturers should use nonhazardous material or less toxic chemicals to reduce exposure of VOCs, PBDEs and phthalates. Drivers can reduce the these chemicals by using solar reflectors and avoiding to park under sunlight. [TAF Prev Med Bull 2010; 9(6.000: 665-672

  4. Preliminary Physics Motivation and Engineering Design Assessment of the National High Power Torus

    International Nuclear Information System (INIS)

    In April 2006, Dr. Ray Orbach, Director of the DOE Office of Science, challenged the fusion community to 'propose a new facility... which will put the U.S. at the lead in world fusion science'. Analysis of the gaps between expected ITER performance and the requirements of a demonstration power plant (Demo) pointed to the critical and urgent need to develop fusion-relevant plasma-material interface (PMI) solutions consistent with sustained high plasma performance. A survey of world fusion program indicated that present and planned experimental devices do not advance the PMI issue beyond ITER, and a major dedicated experimental facility is warranted. Such a facility should provide the flexibility and access needed to solve plasma boundary challenges related to divertor heat flux and particle exhaust while also developing methods to minimize hydrogenic isotope retention and remaining compatible with high plasma performance.

    2016-01-01

    Powerful flares from blazars with short ($\\sim$ min) variability timescales are challenging for current models of blazar emission. Here, we present a physically motivated ab initio model for blazar flares based on the results of recent particle-in-cell (PIC) simulations of relativistic magnetic reconnection. PIC simulations demonstrate that quasi-spherical plasmoids filled with high-energy particles and magnetic fields are a self-consistent by-product of the reconnection process. By coupling our PIC-based results (i.e., plasmoid growth, acceleration profile, particle and magnetic content) with a kinetic equation for the evolution of the electron distribution function we demonstrate that relativistic reconnection in blazar jets can produce powerful flares whose temporal and spectral properties are consistent with the observations. In particular, our model predicts correlated synchrotron and synchrotron self-Compton flares of duration of several hours--days powered by the largest and slowest moving plasmoids th...

  7. Perception of risk from automobile safety defects.

    Slovic, P; MacGregor, D; Kraus, N N

    1987-10-01

    Descriptions of safety engineering defects of the kind that compel automobile manufacturers to initiate a recall campaign were evaluated by individuals on a set of risk characteristic scales that included overall vehicle riskiness, manufacturer's ability to anticipate the defect, importance for vehicle operation, severity of consequences and likelihood of compliance with a recall notice. A factor analysis of the risk characteristics indicated that judgments could be summarized in terms of two composite scales, one representing the uncontrollability of the damage the safety defect might cause and the other representing the foreseeability of the defect by the manufacturer. Motor vehicle defects were found to be highly diverse in terms of the perceived qualities of their risks. Location of individual defects within the factor space was closely associated with perceived riskiness, perceived likelihood of purchasing another car from the same manufacturer, perceived likelihood of compliance with a recall notice, and actual compliance rates.

    Intelligent animals have a high degree of curiosity--the intrinsic desire to know--but the mechanisms of curiosity are poorly understood. A key open question pertains to the internal valuation systems that drive curiosity. What are the cognitive and emotional factors that motivate animals to seek information when this is not reinforced by instrumental rewards? Using a novel oculomotor paradigm, combined with reinforcement learning (RL) simulations, we show that monkeys are intrinsically motivated to search for and look at reward-predictive cues, and that their intrinsic motivation is shaped by a desire to reduce uncertainty, a desire to obtain conditioned reinforcement from positive cues, and individual variations in decision strategy and the cognitive costs of acquiring information. The results suggest that free-viewing oculomotor behavior reveals cognitive and emotional factors underlying the curiosity driven sampling of information. PMID:26838344

    Full Text Available Abstract: This study focuses on Japanese pupils’ motivation with other attitudinal attitudes about learning English. The writer surveyed the 5th and 6th grade pupils’ motivation and its effect factors at an elementary school in Japan at the end of the school year 2007 and 2008. The main focus of this study is to find the relationship between motivation and effect factors using both the 2007 and 2008 data and to examine differences of the pupils’ attitudes between 2007 and 2008. Since the 2008 school year, pupils have received lessons by not only an assistant language teacher (ALT but also their home room teachers (HRTs. The finding showed that the 2008 and 2007 results were similar in most valuables, but the value of “Motivation” increased in 2008 compared to the previous year. Furthermore, “people around the learner” influenced on motivation more positively. Finally, this study presented a model which could be suggested as one of the motivational models of Japanese pupils for English activities. The writer concluded that the involvement of HRTs brought about generally good effects on pupils’ attitudes in this elementary school at this point.

    2016-03-01

    While many therapies focus on the reduction of disturbing symptoms, others pursue behavior consistent with personally held values. Based on regulatory focus theory (Higgins, 1997), reducing symptoms is a type of prevention goal while pursuing values is a promotion goal. In the current study, 123 undergraduate students elicited a negative, self-focused emotion-laden cognition. They were then randomly assigned to construe their negative thought as either (a) an impediment to valued behaviors, (b) a cause of unpleasant symptoms, or to one of two control conditions: (c) distraction or (d) no intervention. Then, participants in all groups completed a series of repetitive therapeutic tasks that targeted their elicited negative cognitions. Results showed that participants who construed treatment in terms of valued behavior promotion spent more time on a therapeutic task than all other groups. The group in the unpleasant symptom promotion condition did not differ from either control group. The motivational advantage of value promotion was not accounted for by differences in mood. The present findings suggest that clients may be better motivated through value promotion goals, as opposed to symptom prevention goals. PMID:26956655

    Full Text Available This paper is a brief overview of the evolution of the global automotive industry during the 20th century, with reference to the main manufacturers, oil crises of 1970-1980, and also the global financial and economic crisis that began in 2008. The analyzed period covers the rise of the Asian Continent, beginning with Japan, then South Korea and more recently the emerging countries: China and India. What was predicted 20-25 years ago, became reality: Asia becomes the economic centre of the world, surpassing unexpectedly fast even the Euro-Atlantic area. Regarding Romania, the revival delay of the automobiles industry, led to the loss of the trucks and bus industry, and after a much awaited rehabilitation of car production, this has stuck now at an unsatisfactory level.

    Thermal cycling is the main cause of fatigue failure in automobile exhaust manifolds for which the use of stainless steel now rivals that of cast iron which has been traditionally used. An original fatigue test has been developed by Ugine and ALZ, a stainless steel producer, so as to be able to compare different grades of stainless steel alloys. This test is representative of the thermal conditions encountered in the critical zones of exhaust manifolds. However, it has revealed significant differences in damage processes in the ferritic and austenitic grades tested. The subject of this thesis is the damage processes induced by thermal fatigue in stainless steels used for automotive exhaust manifolds. Two stainless steels were studied: a ferritic grade, F17TNb (17%Cr and stabilized with Ti and Nb), and an austenitic grade, R20-12, containing 20% Cr and 12% Ni. The first objective was to understand the different damage processes induced by thermal fatigue in the ferritic and austenitic grades. The second was to develop a numerical design tool of the thermally tested structures. (author)

    2016-06-01

    We consider the immediate or near-term experimental opportunities offered by some scenarios that could explain the new diphoton excess at the LHC. If the excess is due to a new particle X s at 750 GeV, additional new particles are required, providing further signals. If connected with naturalness, the X s may be produced in top partner decays. Then a t^'overline{t}^' } signal, with t ' → tX s and X s → gg dominantly, might be discovered by reinterpreting 13 TeV SUSY searches in multijet events with low MET and/or a lepton. If X s is a bound state of quirks, the signal events may be accompanied by an unusual number of soft tracks or soft jets. Other resonances including dilepton and photon+jet as well as dijet may lie at or above this mass, and signatures of hidden glueballs might also be observable. If the "photons" in the excess are actually long-lived particles decaying to photon pairs or to electron pairs, there are opportunities for detecting overlapping photons and/or unusual patterns of apparent photon-conversions in either X s or 125 GeV Higgs decays. There is also the possibility of events with a hard "photon" recoiling against a narrow isolated HCAL-only "jet", which, after the jet's energy is corrected for its electromagnetic origin, would show a peak at 750 GeV.

    Full Text Available Background: Providing and maintaining proper oral hygiene is related with the control of initiation and progression of dental caries and periodontal diseases. Objective: To accentuate on the application and effectiveness of standardized motivational program for oral hygiene in children with assessment of OHI-S Green-Vermillion. Methods: The study includes 200 children from 3 to 6 years of age. Comparison and evaluation of effectiveness of toothpastes with different fluoride concentrations regarding proper hygiene status in children. Application of OHI-S by Green-Vermillion. Examined children are divided into two groups. The first group consists of 100 children divided into two subgroups. The subgroup of children aged from 3 to 5 years washed their teeth with toothpaste containing 500 ppm F. The subgroup of children at the age of 6 used toothpaste containing 1000 ppm F. Concerning the second, control group of 100 children no specific motivation activities were provided. Results: Among children being influenced by standardized motivation program combined with application of toothpaste with 500 ppm F, 45% show better oral hygiene level. Among children influenced by standardized motivation program and toothpaste of 1000 ppm F, 20% of them are with improved oral hygiene status. Reduction of the OHI-S values in children from 3 to 5 years is established from 1.92 to 1.16. In children at the age of 6 OHI-S is reduced from 1.67 to 1.14. Conclusion: 1. All children improve their oral hygiene status after a period of training and motivation. 2. In children at high decay risk standardized motivation program should be combined with additional prophylactic approaches.

  3. Female identity discourse in automobile advertisements

    2012-01-01

    Full Text Available The article analyzes the way in which the modern car-advertisement defines the identity of women as potential purchasers – to whom it is designed to get through. The research includes language and iconic instruments by which this type of advertisement aims to create a feminized market of products formerly recognized as traditionally masculine. The identification of the addressee of each publicity material might be subsumed under a set of stereotypes, thus enabling advertisers to get across their message using the code of addressee’s own values. The present paper concentrates on the linguistic specifity of the ads for high-tech goods (automobiles targeting the feminine public and eventually points out their high degree of markedness according to the sex of addressees. Discourse analysis and a closer look at linguistic means appearing in French, Spanish and Polish automotive commercials both reveals a stereotyped woman’s image and shows how they happen to perpetutate it.

  4. PRODUCT EFFICIENCY IN THE SPANISH AUTOMOBILE MARKET

    González, Eduardo

    2013-01-01

    Full Text Available This paper evaluates product efficiency in the Spanish automobile market. We use non parametric frontier techniques in order to estimate product efficiency scores for each model. These scores reflect the minimum price for which each car could be sold, given the bundle of tangible features it offers in comparison to the best-buy models. Unlike previous research, we use discounted prices which have been adjusted by car dealerships to meet sale targets. Therefore, we interpret the efficiency scores as indicators of the value of the intangible features of the brand. The results show that Audi, Volvo, Volkswagen and Mercedes offer the greatest intangible value, since they are heavily overpriced in terms of price/product ratios. Conversely, Seat, Kia, Renault and Dacia are the brands that can be taken as referent in terms of price/product ratios.

    2005-11-01

    The automobile manufacturing industry plays a very important role in a country's economy. The importance of automobile manufacturing industry lies in its sheer size and complexity in terms of the direct and indirect influence it commands across many other industries. While millions of people are employed in the automobile manufacturing industry, it is estimated that more than two and half times that number are employed in the auxiliary companies that supply parts to the automobile manufacturing companies. The auxiliary companies represent a group of businesses of various sizes, types, and geographical locations, producing a vast variety of products ranging from the very simple to the extremely intricate. In this study, the current environmental practices of management in the core Spanish auxiliary companies that do business with the automobile manufacturing industry (and thus form a large part of the automobile manufacturing industry's supply chain) are investigated. We show that while automobile manufacturing companies are under scrutiny to become more and more environmentally friendly, not only at their manufacturing stage but also at their products' useful and EOL stages, there appears to be no such burden on the auxiliary companies. Our conclusion is based on an elaborate survey conducted during the fall of 2004 of Spanish auxiliary companies with questions about the characteristics, environmental practices and reverse logistics related activities carried out by the companies.

  8. Divorce your car: ending the love affair with the automobile

    2000-07-01

    This book is a guide for people wishing to liberate themselves from their addiction to cars and the automobile culture. It is a repository of examples and actions that individuals and communities can take to reduce dependence on the automobile. The range of possibilities run from using cars less to not owning one at all. The book provides a humorous yet clear-headed approach to a greener world and maps out the road to how people can live happily ever after by breaking free of 'auto-cracy', without insisting on people in car-dependent countries quit their automotive addiction instantly. Nevertheless, it clearly articulates the connection between automobiles, their arteries (i.e. highways) and effluents (i.e. greenhouse gases and particulate emissions), and the increasing number and severity of natural disasters between the urban renewal and freeway construction that, in the author's view, helped ignite the riots in Watts, Newark and Detroit. The disastrous societal and geophysical effects of the automobile are demonstrated in great abundance, and the mountain of evidence of the systematic abuse of the planet that the book provides is a stunning refutation of the notion that technology is neutral. The automobile is accused of being not only the linchpin of Western and primarily American industrialism and resource extraction, it is also accused of being the chief suspect in a century-long theft of time, conviviality and beauty. How to bring about a change in people's love affair with their cars is difficult to comprehend but this author has a multitude of useful suggestions which seem to suggest that it is possible. There is a list of 104 'selected references' and an extensive list of 'other resources'.

  10. Goal hierarchy: Improving asset data quality by improving motivation

    International Nuclear Information System (INIS)

    Many have recognized the need for high quality data on assets and the problems in obtaining them, particularly when there is a need for human observation and manual recording. Yet very few have looked at the role of the data collectors themselves in the data quality process. This paper argues that there are benefits to more fully understanding the psychological factors that lay behind data collection and we use goal hierarchy theory to understand these factors. Given the myriad of potential reasons for poor-quality data it has previously proven difficult to identify and successfully deploy employee-driven interventions; however, the goal hierarchy approach looks at all of the goals that an individual has in their life and the connections between them. For instance, does collecting data relate to whether or not they get a promotion? Stay safe? Get a new job? and so on. By eliciting these goals and their connections we can identify commonalities across different groups, sites or organizations that can influence the quality of data collection. Thus, rather than assuming what the data collectors want, a goal hierarchy approach determines that empirically. Practically, this supports the development of customized interventions that will be much more effective and sustainable than previous efforts. - Highlights: → We need to consider psychological aspects of data collectors to improve data quality. → We show how goal hierarchy theory furthers understanding. → Looks at the multiple goals of each individual to determine their behavior.

  13. Weight Penalty Incurred in Thermoelectric Recovery of Automobile Exhaust Heat

    Science.gov (United States)

    Rowe, D. M.; Smith, J.; Thomas, G.; Min, G.

    2011-05-01

    Thermoelectric recovery of automobile waste exhaust heat has been identified as having potential for reducing fuel consumption and environmentally unfriendly emissions. Around 35% of combustion energy is discharged as heat through the exhaust system, at temperatures which depend upon the engine's operation and range from 800°C to 900°C at the outlet port to less than 50°C at the tail-pipe. Beneficial reduction in fuel consumption of 5% to 10% is widely quoted in the literature. However, comparison between claims is difficult due to nonuniformity of driving conditions. In this paper the available waste exhaust heat energy produced by a 1.5 L family car when undergoing the new European drive cycle was measured and the potential thermoelectric output estimated. The work required to power the vehicle through the drive cycle was also determined and used to evaluate key parameters. This enabled an estimate to be made of the engine efficiency and additional work required by the engine to meet the load of a thermoelectric generating system. It is concluded that incorporating a thermoelectric generator would attract a penalty of around 12 W/kg. Employing thermoelectric modules fabricated from low-density material such as magnesium silicide would considerably reduce the generator weight penalty.

    This paper, whose purpose is mainly historical and pedagogical, suggests that concepts introduced in the ancient Greece by Anaximander (isolated flat earth) and Democritus (corpuscles and empty-space) could have led, from some observations and plausible generalizations, to the maximum efficiency and output work of heat engines obtained in the modern time by Carnot (1824). A prolog presents a simple heat engine. After introducing the concept of thermal equilibrium, a model of thermal engine consisting of corpuscle reservoirs is studied in a classical manner. We establish the ideal gas law from the Daniel Bernoulli corpuscular concept (1738) using the corpuscle \\emph{action} concept. This leads to the energy of a gas at any temperature.

  2. The promise of fuel cell-based automobiles

    2003-02-01

    Fuel cell-based automobiles have gained attention in the last few years due to growing public concern about urban air pollution and consequent environmental problems. From an analysis of the power and energy requirements of a modern car, it is estimated that a base sustainable power of $ca$. 50 kW supplemented with short bursts up to 80 kW will suffice in most driving requirements. The energy demand depends greatly on driving characteristics but under normal usage is expected to be 200 Wh/km. The advantages and disadvantages of candidate fuel-cell systems and various fuels are considered together with the issue of whether the fuel should be converted directly in the fuel cell or should be reformed to hydrogen onboard the vehicle. For fuel cell vehicles to compete successfully with conventional internal-combustion engine vehicles, it appears that direct conversion fuel cells using probably hydrogen, but possibly methanol, are the only realistic contenders for road transportation applications. Among the available fuel cell technologies, polymer–electrolyte fuel cells directly fueled with hydrogen appear to be the best option for powering fuel cell vehicles as there is every prospect that these will exceed the performance of the internal-combustion engine vehicles but for their first cost. A target cost of $ 50/kW would be mandatory to make polymer–electrolyte fuel cells competitive with the internal combustion engines and can only be achieved with design changes that would substantially reduce the quantity of materials used. At present, prominent car manufacturers are deploying important research and development efforts to develop fuel cell vehicles and are projecting to start production by 2005.

  3. Phasic Mesolimbic Dopamine Signaling Encodes the Facilitation of Incentive Motivation Produced by Repeated Cocaine Exposure

    Drug addiction is marked by pathological drug seeking and intense drug craving, particularly in response to drug-related stimuli. Repeated psychostimulant administration is known to induce long-term alterations in mesolimbic dopamine (DA) signaling that are hypothesized to mediate this heightened sensitivity to environmental stimuli. However, there is little direct evidence that drug-induced alteration in mesolimbic DA function underlies this hypersensitivity to motivational cues. In the current study, we tested this hypothesis using fast-scan cyclic voltammetry to monitor phasic DA signaling in the nucleus accumbens core of cocaine-pretreated (6 once-daily injections of 15 mg/kg, i.p.) and drug-naive rats during a test of cue-evoked incentive motivation for food—the Pavlovian-to-instrumental transfer task. We found that prior cocaine exposure augmented both reward seeking and DA release triggered by the presentation of a reward-paired cue. Furthermore, cue-evoked DA signaling positively correlated with cue-evoked food seeking and was found to be a statistical mediator of this behavioral effect of cocaine. Taken together, these findings provide support for the hypothesis that repeated cocaine exposure enhances cue-evoked incentive motivation through augmented phasic mesolimbic DA signaling. This work sheds new light on a fundamental neurobiological mechanism underlying motivated behavior and its role in the expression of compulsive reward seeking. PMID:24804846

    Full Text Available The analysis of the motive structure’s features in the play “August: Osage County” by a modern American writer Tr. Letts has been reviewed in this article. His drama is based on a compound of mass and elite, a playing and a moral. It allows to avoid the text’s tendentiousness and to keep the content. In the play “August: Osage County” Tr. Letts examines the family theme, which is very important for the American culture. The author reviews the destruction of family relationships as a sign of the society’s moral crisis. The main topic has been realized via motives (escapism, freedom, death, and incest, they create the semantic frame of the play and unite separate episodes of the plot’s development. The motives become special tools of the characters’ psychological analysis and are an explanation of the feelings’ contradictory. The image of the house has a special meaning. It’s the symbol of the human disunity and a destruction of the family relations. As a result the synthesis of the motives, symbolism, intertextuality, multilayer has been viewed as a particular tool of the author’s opinion realization and the philosophical implication’s creation

    In the state-run health office in Ulm a survey of the frequency of anonymous HIV-antibody tests was taken between 1985 to 1991, of the age and gender representation from 1988 to 1991, of the test motives from 1.1.1990 to 1.3.1991. The result was a regressive trend following the test boom of 1987 and 1988, which is becoming more and more stable. The relation of men and women has been amounting to 6:4 in the last four years; the proportion of women receding slightly but constantly. The main motive of being tested was finding out about a high-risk or potentially high-risk sexual contact, mostly at the beginning of a new partnership. The motive ranking second in frequency was the investigation of the consequences of blood exposure, mostly relating to medical work. The third place was taken by irrational anxieties as a test motive. The article discusses the fact that test at the beginning of a new partnership frequently have the meaning of a sacrifice and a symbol of bondage in combination with a vow to be faithful. In case of irrational anxieties about AIDS the test-counsellor gets a chance to diagnose a possibly neurotic development at a very early stage, so that painful and expensive chronification and generalisation could be stopped or eased.

  7. Optimal Power Flow Control by Rotary Power Flow Controller

    Directory of Open Access Journals (Sweden)

    KAZEMI, A.

    2011-05-01

    Full Text Available This paper presents a new power flow model for rotary power flow controller (RPFC. RPFC injects a series voltage into the transmission line and provides series compensation and phase shifting simultaneously. Therefore, it is able to control the transmission line impedance and the active power flow through it. An RPFC is composed mainly of two rotary phase shifting transformers (RPST and two conventional (series and shunt transformers. Structurally, an RPST consists of two windings (stator and rotor windings. The rotor windings of the two RPSTs are connected in parallel and their stator windings are in series. The injected voltage is proportional to the vector sum of the stator voltages and so its amplitude and angle are affected by the rotor position of the two RPSTs. This paper, describes the steady state operation and single-phase equivalent circuit of the RPFC. Also in this paper, a new power flow model, based on power injection model of flexible ac transmission system (FACTS controllers, suitable for the power flow analysis is introduced. Proposed model is used to solve optimal power flow (OPF problem in IEEE standard test systems incorporating RPFC and the optimal settings and location of the RPFC is determined.

    Full Text Available The paper explores the motivation of human resources in the companies from counties of Satu Mare and Bihor. Data were collected by applying a questionnaire to 114 companies located in the counties of Satu Mare and Bihor, within the project HURO/0901/264/2.2.2 implemented in partnership by "Vasile Goldis" Western University and University of Debrecen and financed by European Union through ERDF under Hungary-Romania 2007- 2013 Programme. Data were processed and analyzed by using the SPSS soft. We found that employers perceived as most efficient the following motivation instruments: a good communication between employees, basic wage, partial delegation of managerial tasks and optimal working conditions. The efficiency of the motivation instruments in the view of employers differs significantly across activity sectors. Thus, using the ANOVA test, we found that the variation of variables related to basic wage, performance rewarding, bonuses, partial delegation of managerial tasks, work competencies, fear of job loss, need for affiliation to a workgroup, the prestige outside the organisation, working a good reputation organisation, social benefits, home distance can be explained in a proportion ranged from 23,5% to 42,9% by the variation of variable associated to the activity sector.

  13. Gender differences in the motivational processing of babies are determined by their facial attractiveness.

    Directory of Open Access Journals (Sweden)

    Rinah Yamamoto

    Full Text Available BACKGROUND: This study sought to determine how esthetic appearance of babies may affect their motivational processing by the adults. METHODOLOGY AND PRINCIPAL FINDINGS: Healthy men and women were administered two laboratory-based tasks: a key pressing to change the viewing time of normal-looking babies and of those with abnormal facial features (e.g., cleft palate, strabismus, skin disorders, Down's syndrome and fetal alcohol syndrome and b attractiveness ratings of these images. Exposure to the babies' images produced two different response patterns: for normal babies, there was a similar effort by the two groups to extend the visual processing with lower attractiveness ratings by men; for abnormal babies, women exerted greater effort to shorten the viewing time despite attractiveness ratings comparable to the men. CONCLUSIONS: These results indicate that gender differences in the motivational processing of babies include excessive (relative to the esthetic valuation motivation to extend the viewing time of normal babies by men vs. shortening the exposure to the abnormal babies by women. Such gender-specific incentive sensitization phenomenon may reflect an evolutionary-derived need for diversion of limited resources to the nurturance of healthy offspring.

    Design of an acceleration measurement system using a MEMS accelerometer to measure acceleration of automobiles in all the three axes is presented. Electronic stability control and anti-lock breaking systems in automobiles use the acceleration measurements to offer safety in driving. The system uses an ARM microcontroller to quantize the outputs of accelerometer and save the measurement data on a microSD card. A LabVIEW program has been developed to analyze the longitudinal acceleration measurement data and test the measurement system. Random noises generated and added with measurement data during measurement are filtered by a Kalman filter implemented in LabVIEW. Longitudinal velocity of the vehicle is computed from the measurement data and displayed on a graphical chart. Typical measurement of velocity of a vehicle at different accelerations and decelerations is presented.

    YAN Shuwang; ZHANG Xinqiang; LIU Run

    2004-01-01

    An FE analysis procedure was presented to predict the behavior of soil-geogrid interaction under automobile loading. The dynamic interactions between the transverse bars, the longitudinal ribs and the soil were simulated by a system consisting of nonlinear springs, dashpots and masses, to study the deformation properties of the reinforced soil. The equivalent stiffness and damping ratios could be determined with the shaking table. The dynamic responses of a reinforced subgrade were analyzed with the 3D finite element approach. This approach is programmed and applied to analyze the soil-geogrid interaction under dynamic loading. The comparative analysis of the response of the reinforced subgrade and that of the subgrade without reinforcement shows that the geogrid placed at the bottom of the base layer may effectively reduce the accumulative plastic deformation due to the cyclic automobile loading.

    Interventions aimed at influencing spending behavior and risk-taking have considerable practical importance. A number of studies motivated by the costly signaling theory within evolutionary psychology have reported that priming inductions (such as looking at pictures of attractive opposite sex members) designed to trigger mating motives increase males' stated willingness to purchase conspicuous consumption items and to engage in risk-taking behaviors, and reduce loss aversion. However, a meta-analysis of this literature reveals strong evidence of either publication bias or p-hacking (or both). We then report 8 studies with a total sample of over 1,600 participants which sought to reproduce these effects. None of the studies, including one that was fully preregistered, was successful. The results question the claim that romantic primes can influence risk-taking and other potentially harmful behaviors. PMID:26501730

    Territoriality has an extensive and thorough history of research, but has been difficult to impossible to test empirically in most species. We offer a method for testing for territoriality by measuring the motivation of territory intruders to win contests in controlled trials. We demonstrated this approach by staging paired trials of the Amblypygi Phrynus longipes (Chelicerata: Arachnida). Amblypygids engaged in agonistic interactions after the opportunity to establish a putative territory on one side of an arena. We found that intruders of putative territories had lower motivation to win contests, thus evidencing territoriality. Physical components of individuals (i.e. energy stores) increased the probability of winning the contest for holders but not intruders, thereby providing insight into the differing decision rules opponents use in territory contests. We discuss why alternative hypotheses, including loser-initiator covariation and home field bourgeois advantage, fail empirical tests. We demonstrated that analyzing animal motivation in territorial contests is tractable even for animals where territories are inconspicuous and cues are outside the normal perceptions of researchers.

Compare and analyze the structural style of semi-initiative and initiative control and merits and demerits of current structures of semi-initiative and initiative control of mechanic electrorheological, magnetorheological, electromagnetic actuator, piezoelectric ceramics, electrostriction material, pneumatic actuator etc. Models of power assembly mounting system was classified.Calculation example indicated that reasonable selection of engine mounting system parameters is useful to reduce engine vibration transmission and to increase ride comfort. Finally we brought forward semi-initiative and initiative suspension which might be applied for automobiles, and which has a promising future.

  10. Temporal dynamics of motivation-cognitive control interactions revealed by high-resolution pupillometry

    Directory of Open Access Journals (Sweden)

    Kimberly Sarah Chiew

    2013-01-01

    Full Text Available Motivational manipulations, such as the presence of performance-contingent reward incentives, can have substantial influences on cognitive control. Previous evidence suggests that reward incentives may enhance cognitive performance specifically through increased preparatory, or proactive, control processes. The present study examined reward influences on cognitive control dynamics in the AX-Continuous Performance Task (AX-CPT, using high-resolution pupillometry. In the AX-CPT, contextual cues must be actively maintained over a delay in order to appropriately respond to ambiguous target probes. A key feature of the task is that it permits dissociable characterization of preparatory, proactive control processes (i.e., utilization of context and reactive control processes (i.e., target-evoked interference resolution. Task performance profiles suggested that reward incentives enhanced proactive control (context utilization. Critically, pupil dilation was also increased on reward incentive trials during context maintenance periods, suggesting trial-specific shifts in proactive control, particularly when context cues indicated the need to overcome the dominant target response bias. Reward incentives had both transient (i.e., trial-by-trial and sustained (i.e., block-based effects on pupil dilation, which may reflect distinct underlying processes. The transient pupillary effects were present even when comparing against trials matched in task performance, suggesting a unique motivational influence of reward incentives. These results suggest that pupillometry may be a useful technique for investigating reward motivational signals and their dynamic influence on cognitive control.

    2015-01-01

    The coupled model of a four-cylinder internal combustion engine and a dash panel was constructed to analyze the relationship between the engine noise and interior noise of an automobile. Finite element analysis, flexible multi-body dynamics, and boundary element analysis were integrated to obtain the tetrahedron-element models, structural vibration response, and radiated noise, respectively. The accuracy of the finite-element model of the engine was validated by modal analysis via single-input multi-output technology, while the dash panel was validated by sound transmission loss experiment. The block was optimized to reduce the radiated acoustic power from the engine surface. The acoustic transfer path between the engine cabin and passenger compartment was then established. The coupled analysis results reveal that the interior noise is optimized due to the engine noise reduction.

  12. Improving electrofishing catch consistency by standardizing power

    Burkhardt, Randy W.; Gutreuter, Steve

    1995-01-01

    The electrical output of electrofishing equipment is commonly standardized by using either constant voltage or constant amperage, However, simplified circuit and wave theories of electricity suggest that standardization of power (wattage) available for transfer from water to fish may be critical for effective standardization of electrofishing. Electrofishing with standardized power ensures that constant power is transferable to fish regardless of water conditions. The in situ performance of standardized power output is poorly known. We used data collected by the interagency Long Term Resource Monitoring Program (LTRMP) in the upper Mississippi River system to assess the effectiveness of standardizing power output. The data consisted of 278 electrofishing collections, comprising 9,282 fishes in eight species groups, obtained during 1990 from main channel border, backwater, and tailwater aquatic areas in four reaches of the upper Mississippi River and one reach of the Illinois River. Variation in power output explained an average of 14.9% of catch variance for night electrofishing and 12.1 % for day electrofishing. Three patterns in catch per unit effort were observed for different species: increasing catch with increasing power, decreasing catch with increasing power, and no power-related pattern. Therefore, in addition to reducing catch variation, controlling power output may provide some capability to select particular species. The LTRMP adopted standardized power output beginning in 1991; standardized power output is adjusted for variation in water conductivity and water temperature by reference to a simple chart. Our data suggest that by standardizing electrofishing power output, the LTRMP has eliminated substantial amounts of catch variation at virtually no additional cost.

    The Navier Stokes equation is solved computationally by the Dispersion-Relation-Preserving (DRP) scheme for the flow and acoustic fields associated with a laminar boundary layer flow over an automobile door cavity. In this work, the flow Reynolds number is restricted to R(sub delta*) < 3400; the range of Reynolds number for which laminar flow may be maintained. This investigation focuses on two aspects of the problem, namely, the effect of boundary layer thickness on the cavity tone frequency and intensity and the effect of the size of the computation domain on the accuracy of the numerical simulation. It is found that the tone frequency decreases with an increase in boundary layer thickness. When the boundary layer is thicker than a certain critical value, depending on the flow speed, no tone is emitted by the cavity. Computationally, solutions of aeroacoustics problems are known to be sensitive to the size of the computation domain. Numerical experiments indicate that the use of a small domain could result in normal mode type acoustic oscillations in the entire computation domain leading to an increase in tone frequency and intensity. When the computation domain is expanded so that the boundaries are at least one wavelength away from the noise source, the computed tone frequency and intensity are found to be computation domain size independent.

    Concepts from theories of motivation are used to suggest methods for improving the motivational environment of hospital pharmacy departments. Motivation--the state of being stimulated to take action to achieve a goal or to satisfy a need--comes from within individuals, but hospital pharmacy managers can facilitate motivation by structuring the work environment so that it satisfies employees' needs. Concepts from several theories of motivation are discussed, including McGregor's theory X and theory Y assumptions, Maslow's hierarchy of needs theory, Herzberg's motivation hygiene theory, and Massey's value system theory. Concepts from the Japanese style of management that can be used to facilitate motivation, such as quality circles, also are described. The autocratic, participative, and laissez faire styles of leadership are discussed in the context of the motivation theories, and suggested applications of theoretical concepts to practice are presented.

  13. Improvements by employee motivation in the manufacture of nuclear fuel assemblies for LWRs

    International Nuclear Information System (INIS)

    Nuclear fuel assemblies are manufactured on a very high technical level and automation. However there is still a need for more improvement. One of the most important ways is employees motivation, because improvements lives of the ideas, impulses, initiatives and commitments of its employees. It can be realized by the employee himself or a group. Three ways of improvement by employees are mainly implemented at ANF: (i) ANF's 3i - program, based on the standard implementation within Siemens, is the first and an important strategy to improve processes, products and costs. It is to involve all employees and make use of the full potential for improvement The individual employee or a group make a suggestion and receive a commendation depending on the benefits. (ii) Work groups with a high level of responsibility are the second part. The groups mainly organize their work, working time and improvements by themselves. They help each other in job training, are very flexible and able to do also most of the maintenance work. (iii) CIP - groups (Continuous Improvement Process), based on the philosophy of KAMEN is the third strategy. These groups come together to improve all processes in the manufacturing area, also the administration or logistical processes at ANF. CIP - groups are implemented as so called long-term groups, the members are from different levels and departments. By comparing the different ways in order to achieve manufacturing improvements, employees motivation is one of the most important and cheapest part and will increase in significance in future.

    2016-02-01

    Affect and motivation influence the error-related negativity (ERN) elicited by full errors; however, it is unknown whether they also influence ERNs to correct responses accompanied by covert incorrect response activation (partial errors). Here we compared a neutral condition with conditions, where correct responses were rewarded or where incorrect responses were punished with gains and losses of small amounts of money, respectively. Data analysis distinguished ERNs elicited by full and partial errors. In the reward and punishment conditions, ERN amplitudes to both full and partial errors were larger than in the neutral condition, confirming participants' sensitivity to the significance of errors. We also investigated the relationships between ERN amplitudes and the behavioral inhibition and activation systems (BIS/BAS). Regardless of reward/punishment condition, participants scoring higher on BAS showed smaller ERN amplitudes in full error trials. These findings provide further evidence that the ERN is related to motivational valence and that similar relationships hold for both full and partial errors. PMID:26747414

    Monitoring parameters characterizing water quality, such as temperature, pH, and concentrations of heavy metals in natural waters, is often followed by transmitting the data to remote receivers using telemetry systems. Such systems are commonly powered by batteries, which can be inconvenient at times because batteries have a limited lifetime and must be recharged or replaced periodically to ensure that sufficient energy is available to power the electronics. To avoid these inconveniences, a microbial fuel cell was designed to power electrochemical sensors and small telemetry systems to transmit the data acquired by the sensors to remote receivers. The microbial fuel cell was combined with low-power, high-efficiency electronic circuitry providing a stable power source for wireless data transmission. To generate enough power for the telemetry system, energy produced by the microbial fuel cell was stored in a capacitor and used in short bursts when needed. Since commercial electronic circuits require a minimum 3.3 V input and our cell was able to deliver a maximum of 2.1 V, a DC-DC converter was used to boost the potential. The DC-DC converter powered a transmitter, which gathered the data from the sensor and transmitted it wirelessly to a remote receiver. To demonstrate the utility of the system, temporal variations in temperature were measured, and the data were wirelessly transmitted to a remote receiver. PMID:16053108

    Research has demonstrated that the motive triad of needs for achievement, power, and affiliation can predict variables such as occupational success and satisfaction, innovation, aggressiveness, susceptibility to illness, cooperation, conformity, and many others. The present study documents the motivational profiles of astronauts at three stages of their expedition. Thematic content analysis was employed for references to Winter's well-established motive markers in narratives (media interviews, journals, and oral histories) of 46 astronauts participating in International Space Station (ISS) expeditions. Significant pre-flight differences were found in relation to home agency and job status. NASA astronauts, compared with those from the Russian Space Agency, are motivated by higher need for power, as are commanders in comparison to flight engineers. The need for affiliation motive showed a significant change from pre-flight to in-flight stages. The implications of the relationship between the motivational profile of astronauts and the established behavioural correlates of such profiles are discussed.

    The radiologic career field has undergone radical changes in technology, regulatory compliance, and customer expectation.These changes often require dramatic alterations to processes,which can break down communication, create stress, and have a negative effect on department productivity. Motivation itself is a frequently analyzed and reported topic in professional publications. For this purpose, this literature review specifically researches motivation as identified by radiology administrators through Radiology Management. Three key elements surfaced as those with the most impact: (1) motivation is an intrinsic factor which can be influenced but not created, (2) clear attainable goals are an essential component of motivation,and (3) motivation begins with identification of employee needs.

  19. Electric peak power forecasting by year 2025

    International Nuclear Information System (INIS)

    Peak power demand in Kuwait up to the year 2025 was predicted using an artificial neural network (ANN) model. The aim of the study was to investigate the effect of air conditioning (A/C) units on long-term power demand. Five socio-economic factors were selected as inputs for the simulation: (1) gross national product, (2) population, (3) number of buildings, (4) imports of A/C units, and (5) index of industrial production. The study used socio-economic data from 1978 to 2000. Historical data of the first 10 years of the studied time period were used to train the ANN. The electrical network was then simulated to forecast peak power for the following 11 years. The calculated error was then used for years in which power consumption data were not available. The study demonstrated that average peak power rates increased by 4100 MW every 5 years. Various scenarios related to changes in population, the number of buildings, and the quantity of A/C units were then modelled to estimate long-term peak power demand. Results of the study demonstrated that population had the strongest impact on future power demand, while the number of buildings had the smallest impact. It was concluded that peak power growth can be controlled through the use of different immigration policies, increased A/C efficiency, and the use of vertical housing. 7 refs., 2 tabs., 6 figs

    The large penetration of wind farm into interconnected power systems may cause the severe problem of tie-line power oscillations. To suppress power oscillations, the superconducting magnetic energy storage (SMES) which is able to control active and reactive powers simultaneously, can be applied. On the other hand, several generating and loading conditions, variation of system parameters, etc., cause uncertainties in the system. The SMES controller designed without considering system uncertainties may fail to suppress power oscillations. To enhance the robustness of SMES controller against system uncertainties, this paper proposes a robust control design of SMES by taking system uncertainties into account. The inverse additive perturbation is applied to represent the unstructured system uncertainties and included in power system modeling. The configuration of active and reactive power controllers is the first-order lead-lag compensator with single input feedback. To tune the controller parameters, the optimization problem is formulated based on the enhancement of robust stability margin. The particle swarm optimization is used to solve the problem and achieve the controller parameters. Simulation studies in the six-area interconnected power system with wind farms confirm the robustness of the proposed SMES under various operating conditions.

    Environmental sustainability and green environmental issues have an increasing popularity among researchers and supply chain practitioners. An attempt has been made to identify and empirically analyze green supply chain management (GSCM) practices in Indian automobile industry. Six main GSCM practices (having 37 sub practices) and four expected performance outcomes (having 16 performances) have been identified by implementing GSCM practices from literature review. Questionnaire based survey has been made to validate these practices and performance outcomes. 123 complete questionnaires were collected from Indian automobile organizations and used for empirical analysis of GSCM practices in Indian automobile industry. Descriptive statistics have been used to know current implementation status of GSCM practices in Indian automobile industry and multiple regression analysis has been carried out to know the impact on expected organizational performance outcomes by current GSCM practices adopted by Indian automobile industry. The results of study suggested that environmental, economic, social and operational performances improve with the implementation of GSCM practices. This paper may play an important role to understand various GSCM implementation issues and help practicing managers to improve their performances in the supply chain.

  4. Top-down response suppression mitigates action tendencies triggered by a motivating stimulus.

    Science.gov (United States)

    Freeman, Scott M; Razhas, Ieva; Aron, Adam R

    2014-01-20

    Motivating stimuli provoke action tendencies that sometimes lead to unwanted behavior (e.g., eating chocolate when trying to diet). Implementing control over these provocations is essential to healthy functioning; however, few laboratory-based models of such control exist. Here we developed a novel task in which thirsty human subjects made instrumental responses to obtain a juice reward (Go trials) or were required to withhold responding (NoGo trials) in the presence of a rewarded (CS+) or unrewarded (CS-) conditioned stimulus. For Go trials, single-pulse transcranial magnetic stimulation revealed a rapid increase in motor activity for CS+ versus CS-, preceding more vigorous instrumental responding. Critically, successful NoGo trials resulted in suppression of motor activity for CS+, but not CS-. Moreover, while there was broad excitation in the hand muscles in Go trials, suppression in NoGo trials was selective to the effector that could obtain reward. These results show that response suppression can be triggered by a motivational stimulus, thus providing a richer model of self-control than classic cognitive psychology paradigms.

    2014-01-01

    Full Text Available An integrative teaching methodology was developed by qualified specialists and implemented in 17 Latvian schools during one study year. Students who participated in the learning of integrative teaching methodology were divided into 3 age groups: 3–4; 5–7 and 8–12 grade students. Students and teachers who participated in the teaching of integrative teaching methodology were questionnaire before and after using of this methodology. The questionnaires about self-organization problems, relations between students and behaviour of students were filled by teachers but the questionnaire about the learning motivation of students was filled by students themselves. The results of questionnaire showed that problems of self-organization, motivation, hyperactivity, attention deficiency, social anxiety, communication and depressive symptomatic of students who were taught according to the integrative teaching methodology of general schools have reduced in all age groups but in 5–7 and 8–12 grade groups of student's aggressive behaviour reduced as well. Self-organization and behaviour problems of students from special schools after realizing integrative teaching methodology have less reduced in comparison with students of general education schools. In general education schools as well as in special schools external learning motivation and internal learning motivation of all age students increased but am motivation or lack of motivation to learn decreased.

    Full Text Available The study of the motivation of construction workers is limited to a relatively small body of knowledge. Although there is considerable research available regarding motivation and productivity, few researchers have provided a comprehensive analysis on the motivation of construction workers. The research stated that productivity in construction has not improved compared to other industry sectors such as manufacturing. This trend has been echoed in publications throughout the past five decades, and suggested that motivation is one of the key factors impacting productivity. This paper offers a comprehensive review of the published work that directly links the key words—construction and motivation. The findings have been presented in five themes, that is, motivation models, environment and culture, incentives and empowerment, and worker management. This paper concludes with two methods suggested by previous researchers to improve motivation of construction workers: (1 relevant worker incentives (intrinsic or extrinsic and (2 improved management practices, specifically regarding communication with workers.

    Obesity is a constantly escalating problem in all age groups. In the face of ubiquitous images of food, colourful advertisements of high-calorie meals and beverages, it is necessary to examine the role of the memory and attention mechanism in the processing of these stimuli. Knowledge regarding this subject will surely significantly contribute to the improvement of prevention and management of obesity programs designed to prevent secondary psychological difficulties, including depression. This paper presents cognitive-motivational model of obesity, according to which the description of mechanisms of eating disorders occurrence should include not only motivational factors but also the cognitive ones. The paper shows theoretical perspectives on the problem of obesity irrespective of its origin, as well as the latest empirical reports in this field. The presented survey demonstrates the lack of explicit research findings related to the processing of high and low-calorie food images by persons with excess weight. It seems that the knowledge of the basic mechanisms involved in the processing of these stimuli and the exploration of this phenomenon will allow to improve programs whose objective is to prevent obesity.

    Despite the important role of motivation in rehabilitation and functional outcomes in schizophrenia, to date, there has been little emphasis on how motivation is assessed. This is important, since different measures may tap potentially discrete motivational constructs, which in turn may have very different associations to important outcomes. In the current study, we used baseline data from 71 schizophrenia spectrum outpatients enrolled in a rehabilitation program to examine the relationship between task-specific motivation, as measured by the Intrinsic Motivation Inventory (IMI), and a more general state of volition/initiation, as measured by the three item Quality of Life (QLS) motivation index. We also examined the relationship of these motivation measures to demographic, clinical and functional variables relevant to rehabilitation outcomes. The two motivation measures were not correlated, and participants with low general state motivation exhibited a full range of task-specific motivation. Only the QLS motivation index correlated with variables relevant to rehabilitation outcomes. The lack of associations between QLS motivation index and IMI subscales suggests that constructs tapped by these measures may be divergent in schizophrenia, and specifically that task-specific intrinsic motivation is not contingent on a general state of motivation. That is, even in individuals with a general low motivational state (i.e. amotivation), interventions aimed at increasing task-specific motivation may still be effective. Moreover, the pattern of interrelationships between the QLS motivation index and variables relevant to psychosocial rehabilitation supports its use in treatment outcome studies.

  18. Contribution of Road Grade to the Energy Use of Modern Automobiles Across Large Datasets of Real-World Drive Cycles: Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Wood, E.; Burton, E.; Duran, A.; Gonder, J.

    2014-01-01

    Understanding the real-world power demand of modern automobiles is of critical importance to engineers using modeling and simulation to inform the intelligent design of increasingly efficient powertrains. Increased use of global positioning system (GPS) devices has made large scale data collection of vehicle speed (and associated power demand) a reality. While the availability of real-world GPS data has improved the industry's understanding of in-use vehicle power demand, relatively little attention has been paid to the incremental power requirements imposed by road grade. This analysis quantifies the incremental efficiency impacts of real-world road grade by appending high fidelity elevation profiles to GPS speed traces and performing a large simulation study. Employing a large real-world dataset from the National Renewable Energy Laboratory's Transportation Secure Data Center, vehicle powertrain simulations are performed with and without road grade under five vehicle models. Aggregate results of this study suggest that road grade could be responsible for 1% to 3% of fuel use in light-duty automobiles.

  8. Individualized solutions to environmental problems: a case of automobile pollution

    Air pollution associated with motor vehicle use is one of the prime indicators of the tension between consumerism and the environment. The use of private automobiles seems so convenient, whereas the alternatives are off-putting enough to make significant changes in personal transportation behaviour well-nigh impossible. At the same time, combating the air pollution associated with extensive use of cars has become one of the major policy objectives for cities around the world. Available policy alternatives can be divided into two categories: (1) incentives, such as improved public transportation, and (2) disincentives, such as environmental tax on gasoline. This paper attempt to directly assess links between these two alternatives, associated attitudes towards them, the level of public support for command and control (i.e. regulatory) policy approaches as well as for economic incentive/disincentive policies. Answers are sought and findings discussed relative to the link between opinions about the environment and support for different types of environmental policies, the usefulness of a rational choice perspective in explaining support for environmental policy alternatives, the role that partisan political attachments play in support of environmental policy approaches, and the roles played by environmental activism, knowledge, and action in shaping support for environmental policy alternatives. Overall results indicate that while most people living in urban environments support the ideas of environmental protection and would be willing to incur costs to confront the problem, exposure to air pollution plays an inconsequential (actually nearly non-existent) role in support of automobile-related environmental problems. Automobile users act like 'free-riders' i.e. they tend to support policies that socialize the cost of solutions rather than policies that attempt to pass the cost of pollution directly on to individual car owners.

    This report gives the results of the Pyrolysis Collaborative Project organized by the International Energy Agency (IEA) under Biomass Agreement. The participating countries or organizations were Canada, European Community (EC), Finland, United States of America, and the United Kingdom. The overall objective of the project was to establish baseline assessments for the performance and economics of power production from biomass. Information concerning the performance of biomass-fuelled power plants based on gasification is rather limited, and even less data is available of on pyrolysis based power applications. In order to gain further insight into the potential for these technologies, this study undertook the following tasks: (1) Prepare process models to evaluate the cost and performance of new advanced biomass power production concepts, (2) Assess the technical and economic uncertainties of different biomass power concepts, (3) Compare the concepts in small scale and in medium scale production (5 - 50 MW{sub e}) to conventional alternatives. Processes considered for this assessment were biomass power production technologies based on gasification and pyrolysis. Direct combustion technologies were employed as a reference for comparison to the processes assessed in this study. Wood was used a feedstock, since the most data was available for wood conversion

    Full Text Available One of the greatest challenges of developing countries today is electric power generation. The demand for Electric power is far above generation and distribution capacities. For instance, only about 4000MW of electricity is available for nearly 170 million people in Nigeria today. On the other hand, the cities are littered with municipal solid wastes in open dumps which are dangerous to health and environment. Sustainable and successful waste management should be safe, effective, environmentally friendly and economically viable.Application of plasma Physics in waste to energy can be one of the novel ways of sustainable power generation. In plasma gasifying cupola, the organic waste materials are gasified to generate a syngas and steam which can be used to generate electricity by integrated gasification combine circle. The inorganic part of the waste is vitrified to a benign residue used for construction. This paper describes the physics and technology involved, reviews the power situation in Nigeria and the benefits of implementation of this technology in waste to electric power generation. This might be an environmentally Safe and sustainable economic solution for waste management and alternative clean power generation

    The recent economic crisis has forced many universities to cut down expenses by packing students into large lecture groups. The problem with large auditoria is that they discourage dialogue between students and faculty and they burden participation. Adding to this, students in computer science courses usually find the field to be full of theoretical and technical concepts. Lack of understanding leads them to lose interest and / or motivation. Classroom experience shows that the lecturer could employ alternative teaching methods, especially for early-year undergraduate students, in order to grasp their interest and introduce basic concepts. This paper describes some of the approaches that may be used to keep students interested and make them feel comfortable as they comprehend basic concepts in computer networks. The lecturing procedure was enriched with games, magic tricks and dramatic representations. This approach was used experimentally for two semesters and the results were more than encouraging.

    A regulation task which subjected the automobile to a random gust disturbance which is countered by driver control action is used to study the effects of various automobile steering characteristics on the driver/vehicle system. The experiments used a variable stability automobile specially configured to permit insertion of the simulated gust disturbance and the measurement of the driver/vehicle system characteristics. Driver/vehicle system dynamics were measured and interpreted as an effective open loop system describing function. Objective measures of system bandwidth, stability, and time delays were deduced and compared. These objective measures were supplemented by driver ratings. A tentative optimum range of vehicle dynamics for the directional regulation task was established.

    Adolescence is a particularly vulnerable period for the onset of substance use disorders and other psychopathology. Individual variability in motivational tendencies and temperament and significant changes in functional brain organization during adolescence are important factors to consider in the development of substance use and dependence. Recent conceptualizations suggest that sensitivity to reward is heightened in adolescence and that this motivation tendency may precipitate subsequent substance abuse. The present study examined the role of personality traits in mesolimbic neurobehavioral response on a monetary incentive delay (MID) task in young adolescents (11-14 years) and emerging adults (18-25 years) using functional magnetic resonance imaging. As a group, adolescents were not more sensitive to gains than losses compared to adults during either anticipatory and feedback phases; instead, compared to adults they showed less sensitivity to incentive magnitude in mesolimbic circuitry during anticipation and feedback stages. However, personality modulated this response such that adolescents high in impulsivity or low in avoidance tendencies showed greater gain sensitivity and adolescents high in avoidance showed greater loss sensitivity during cue anticipation. In adults, mesolimbic response was modulated by the impulsivity construct such that high-impulsive adults showed reduced magnitude sensitivity during both anticipation and feedback compared to low impulsive adults. The present findings suggest that impulsive personality significantly modulates mesolimbic reward response during both adolescence and adulthood but avoidance and approach tendencies also modulate this response in adolescents. Moreover, personality modulated incentive valence in adolescents but incentive magnitude in adults. Collectively, these findings suggest that mesolimbic reward circuitry function is modulated by somewhat different parameters in adolescence than in adulthood.

    The paper analyzes the relationship between motivation and volitional processes as described by current motivation theories. The root of the separation between both moments of behavioris traced back to Tetens and Kant’s threefold view of the mind. Sensory perception is reduced to feeling and the will to energy without a proper object. The history of this conception isoutlined. Nuttin’s motivation theory is presented as an alternative to the limitations of other contemporary theories. Some edu...

  5. Ionospheric modification by high-power radio waves

    International Nuclear Information System (INIS)

    Powerful, high-frequency radio waves have been used to temporarily modify the ionosphere. Thermal and parametric interactions have led to a diverse range of observed phenomena, including generation of density striations and artificial spread-F, enhancements of electron plasma waves, production of extrathermal electron fluxes and enhanced airglow, modification of the D-region temperature and densities, wideband signal attenuation, and self-focusing and scattering of the electromagnetic waves. The physics of ionospheric modification by high-power radio waves is reviewed in the context of our current theoretical understanding; disturbance generation mechanisms are qualitatively described. In addition, results of recent experiments are summarized in which ionospheric irregularities are generated and their evolution and decay processes investigated in detail. The effects and potential controlled applications of these HF ionospheric modifications for various RF systems studies are discussed. The C3I scientific community provides an important motivation for these ionospheric modification studies; their increased interaction and active participation in experimental design and interpretation are encouraged

    This report explores the visibility of an Electroluminescent (EL) display for automotive use. Displays for automobiles are exposed to the direct rays of the sun and forced to operate in wide temperature range. Therefore, luminous flux density by the lighting on EL display panel and operating environment temperature must be considered for the visibility evaluation. Sensory evaluation on the visibility and physical measurements such as contrast, chromaticity difference in accordance with the viewing angle change indicate that the visibility of the EL display for automobiles is advantageous over other displays. 6 refs., 11 figs., 1 tab.

    2013-02-01

    Since the automobile turbochargers are installed in an engine compartment with limited space, the ducts upstream of the turbocharger compressor may be curved in a complex manner. In the present paper, the effect of a curved duct upstream on performance of small centrifugal compressors for automobile turbochargers is discussed. The computational fluid dynamics (CFD) analysis of a turbocharger compressor validated for the compressor model with the straight pipe applied to the compressor with the curved pipe are executed, and the deterioration of the performance for the curved pipe is confirmed. It is also found that the deterioration of compressor performance is caused by the interaction of the secondary flow and the impeller.

    Full Text Available Motivation in sport performance has been an interesting topic for many investigators during the past decade. This area can be considered from different viewpoints: motivation for participation in sport activity, achievement motivation, competitiveness etc. Motivation plays an important role in all out tests, as well as in sport activities and at all levels of competition. Motivation climate, or positive social environment may influence and modulate motivation of individuals involved in sports. Experience has shown that conventional encouragement and feedback during the test may affect its outcome. According to Wingate research team recommendations, verbal encouragement, as a motivation factor, was given to all examined subjects during Wingate anaerobic test, which is considered the most reliable test for assessing anaerobic capacity. The investigated group consisted of 30 young men - medical students, who were not actively involved in any programmed sport activity. The investigated group included second-year students of the Faculty of Medicine in Novi Sad chosen by random sampling. The Wingate anaerobic test was performed in all subjects, and changes of parameters when test was performed with verbal encouragement, were recorded. The results show statistically significant increase of Wingate test parameters when conducted with verbal encouragement: anaerobic power (622/669 W; relative anaerobic power (7.70/8.27 W/kg; slope of the power (95.5/114 W/s; relative slope of the power (1.18/1.40 W/s/kg; anaerobic capacity (12.7/13.2 kJ and relative anaerobic capacity (158/164 J/kg.

    Full Text Available Asbestos has been used for so long as automobile brake lining material because of its good physical and chemical properties. However, due to the health hazard associated with its handling, it has lost favour and several alternative materials are being increasingly used. Asbestos-free brake lining was developed in this work using pulverized cow hooves along with epoxy resin, barium sulphate, graphite and aluminium oxide. This was with a view to exploiting the characteristics of cow hooves, which are largely discarded as waste materials to replace asbestos which has been found to be carcinogenic. Samples of brake linings were produced using compressive moulding in which the physical and mechanical properties of the samples were studied. The results obtained showed that proper bonding was achieved as the percentage by weight of epoxy resin increased and percentage by weight of pulverized cow hooves decreased. The hardness, compressive strength, coefficient of friction, water and oil absorption, relative density and wear rate of the brake linings were determined and compared with existing brake lining properties. The result indicates that pulverized cow hooves can be used as brake lining material for automobiles.

    2012-01-01

    Through harvesting energy by wireless charging and delivering data by wireless communication, this study proposes the concept of a wireless sensor enabled by wireless power (WPWS) and reports the fabrication of a prototype for functional tests. One WPWS node consists of wireless power module and sensor module with different chip-type sensors. Its main feature is the dual antenna structure. Following RFID system architecture, a power harvesting antenna was designed to gather power from a standard reader working in the 915 MHz band. Referring to the Modbus protocol, the other wireless communication antenna was integrated on a node to send sensor data in parallel. The dual antenna structure integrates both the advantages of an RFID system and a wireless sensor. Using a standard UHF RFID reader, WPWS can be enabled in a distributed area with a diameter up to 4 m. Working status is similar to that of a passive tag, except that a tag can only be queried statically, while the WPWS can send dynamic data from the sensors. The function is the same as a wireless sensor node. Different WPWSs equipped with temperature and humidity, optical and airflow velocity sensors are tested in this study. All sensors can send back detection data within 8 s. The accuracy is within 8% deviation compared with laboratory equipment. A wireless sensor network enabled by wireless power should be a totally wireless sensor network using WPWS. However, distributed WPWSs only can form a star topology, the simplest topology for constructing a sensor network. Because of shielding effects, it is difficult to apply other complex topologies. Despite this limitation, WPWS still can be used to extend sensor network applications in hazardous environments. Further research is needed to improve WPWS to realize a totally wireless sensor network. PMID:23443370

    Aiming at the fatigue and comfort issues of human-machine contact Interface in automobile driving and based on physiological and anatomical principle, the physiological and biochemical process of muscles and nerves in the formation and development of fatigue is analyzed systematically. The fatigue-causing physiological characteristic Indexes are mapped to biomechanical Indexes like muscle stress-strain, the compression deformation of Wood vessels and nerves etc.from the perspective of formation mechanism. The geometrical model of skeleton and parenchyma is established by applying CT-scanned body data and MRI images. The general rule of comfort body pressure distribution is acquired through the analysis of anatomical structure of buttocks and femoral region. The comprehensive lest platform for sitting comfort of 3D adjustable contact Interface is constructed. The lest of body pressure distribution of human-machine contact interface and its comparison with subjective evaluation indicates that the biomechanical Indexes of automobile driving human-machine contact interface and body pressure distribution rule studied can effectively evaluate the fatigue and comfort issues of human-machine contact interface and provide theoretical basis for the optimal design of human-machine contact interface.

    This study examined the effect of autonomous motivational priming on motivation, attitudes and intentions towards high-intensity interval training (HIT). Participants (N = 42) performed a graded exercise test to determine their peak aerobic power (WPEAK). At a subsequent testing session, participants were randomised to complete either an autonomous or neutral motivational priming task followed by a 10 × 1 HIT exercise protocol, alternating 1-min bouts of hard (70% WPEAK) and light (12.5% WPEAK) exercises for 20 min. Participants primed with autonomous motivation reported greater enjoyment, P = .009, ηp(2) = .16, and perceived competence, P = .005, ηp(2) = .18, post-exercise compared to those in the neutral priming condition. Participants in the autonomous motivational priming condition also reported more positive attitudes, P = .014, ηp(2) = .14, towards HIT; however, there was no difference between the conditions for task motivation during HIT or intentions, P = .53, ηp(2) = .01, to engage in HIT. These findings highlight autonomous motivational priming as a method of enhancing affective and motivational experiences regarding HIT. PMID:26634389

  12. Gnawing and retrieval of inedible objects by Norway rats: Motivational interactions and habituatory effects.

    Science.gov (United States)

    Wallace, R J

    1994-08-01

    The relation between gnawing and retrieval of inedible, partible objects (wooden blocks) by domestic Norway rats (Rattus norvegicus Berkenhout) was examined by manipulating the tendency to gnaw and testing subsequent retrieval. Experiments 1 and 2 established that rats gnaw wooden blocks but do not ingest them even during food deprivation, and that gnawing declines (habituates) over days for most rats. In Experiment 3, food deprivation produced a decrease in retrieval of blocks that was reversed under subsequent ad lib conditions. This result was confirmed in Experiment 4, which also demonstrated concommitant changes in gnawing and object retrieval as well as effects on component responses of the retrieval sequence. In Experiment 5, continuous exposure to blocks sufficient to reduce gnawing to a low level led to a decline in retrieval of these objects that was not reversed by discontinuing exposure. These results are consistent with the incentive-motivational account of retrieval preferences developed in earlier work, and some inferences are made about the kinds of processes that could mediate the effects of deprivation and habituation.

    2010-10-01

    Full Text Available In the runway model of intracranial self-stimulation (ICSS experimentation, the experimental animal is timed in running a fixed distance to depress a lever that releases electrical stimulation to an electrode implanted along its medial forebrain bundle. This ICSS has both a reward and a motivational component. Using the runway method and priming stimulation, we designed an experimental method for directly measuring motivation. An assessment of pharmacological agents that are known to influence motivational states was also undertaken. Using the experimental methods that we created, we observed prominent changes in running speed when animals were exposed to methamphetamine and nicotine. According to these data, the runway method employing intracranial self-stimulation behavior may be useful for the evaluation of substances that act on motivation. We review the underlying neuropharmacological and anatomical functions associated with our experimental methods. We hope that this technique will be used to scientifically evaluate the impact of drugs and/or therapeutic interventions on human motivation.

    The supply of potable water from polluted rivers, lakes, unsafe wells, etc. is a problem of high priority. One of the most effective methods to obtain low cost drinking water is desalination. Advanced water treatment system powered by Solar Energy and based on electrodialysis for water desalination and purification, is suggested. Technological and economic evaluations and the benefits of the suggested system are discussed. The Advanced Water Treatment System proposed clears water not only from different salts, but also from some infections, thus decreasing the count of diseases which are caused by the usage of non-clear water. Using Solar Energy makes the system stand alone which is convenient to use in places where power supply is problem.

    Dense active matter, from bacterial suspensions and microtubule bundles driven by motor proteins to cellular monolayers and synthetic Janus particles, is characterised by mesoscale turbulence, the emergence of chaotic flow structures. By immersing an ordered array of symmetric rotors in an active fluid, we introduce a microfluidic system that exploits spontaneous symmetry breaking in mesoscale turbulence to generate work. The lattice of rotors self-organises into a spin-state where neighbouring discs continuously rotate in permanent alternating directions due to combined hydrodynamic and elastic effects. Our virtual prototype demonstrates a new research direction for the design of micromachines powered by the nematohydrodynamic properties of active turbulence.

    Grant, Adam M; Hofmann, David A

    2011-12-01

    Diseases often spread in hospitals because health care professionals fail to wash their hands. Research suggests that to increase health and safety behaviors, it is important to highlight the personal consequences for the actor. However, because people (and health care professionals in particular) tend to be overconfident about personal immunity, the most effective messages about hand hygiene may be those that highlight its consequences for other people. In two field experiments in a hospital, we compared the effectiveness of signs about hand hygiene that emphasized personal safety ("Hand hygiene prevents you from catching diseases") or patient safety ("Hand hygiene prevents patients from catching diseases"). We assessed hand hygiene by measuring the amount of soap and hand-sanitizing gel used from dispensers (Experiment 1) and conducting covert, independent observations of health care professionals' hand-hygiene behaviors (Experiment 2). Results showed that changing a single word in messages motivated meaningful changes in behavior: The hand hygiene of health care professionals increased significantly when they were reminded of the implications for patients but not when they were reminded of the implications for themselves.

  7. The Role of Implicit Motives in Strategic Decision-Making: Computational Models of Motivated Learning and the Evolution of Motivated Agents

    Directory of Open Access Journals (Sweden)

    Kathryn Merrick

    2015-11-01

    Full Text Available Individual behavioral differences in humans have been linked to measurable differences in their mental activities, including differences in their implicit motives. In humans, individual differences in the strength of motives such as power, achievement and affiliation have been shown to have a significant impact on behavior in social dilemma games and during other kinds of strategic interactions. This paper presents agent-based computational models of power-, achievement- and affiliation-motivated individuals engaged in game-play. The first model captures learning by motivated agents during strategic interactions. The second model captures the evolution of a society of motivated agents. It is demonstrated that misperception, when it is a result of motivation, causes agents with different motives to play a given game differently. When motivated agents who misperceive a game are present in a population, higher explicit payoff can result for the population as a whole. The implications of these results are discussed, both for modeling human behavior and for designing artificial agents with certain salient behavioral characteristics.

  11. Environmental implications of alternative-fueled automobiles: Air quality and greenhouse gas tradeoffs

    International Nuclear Information System (INIS)

    The authors analyze alternative fuel-powerstrain options for internal combustion engine automobiles. Fuel/engine efficiency, energy use, pollutant discharges, and greenhouse gas emissions are estimated for spark and compression ignited, direct injected (DI), and indirect injected (II) engines fueled by conventional and reformulated gasoline, reformulated diesel, compressed natural gas (CNG), and alcohols. Since comparisons of fuels and technologies in dissimilar vehicles are misleading, the authors hold emissions level, range, vehicle size class, and style constant. At present, CNG vehicles have the best exhaust emissions performance while DI diesels have the worst. Compared to a conventional gasoline fueled II automobile, greenhouse gases could be reduced by 40% by a DI CNG automobile and by 25% by a DI diesel. Gasoline- and diesel-fueled automobiles are able to attain long ranges with little weight or fuel economy penalty. CNG vehicles have the highest penalty for increasing range, due to their heavy fuel storage systems, but are the most attractive for a 160-km range. DI engines, particularly diesels, may not be able to meet strict emissions standards, at least not without lowering efficiency

    2014-10-01

    Full Text Available Motivating people to change their mobility behaviour patterns towards more sustainable forms of mobility is one of the major challenges regarding climate change and quality of life. Recently, an increasing amount of attempts to use gamification for triggering such behavioural changes can be observed. However, little is known about the actual impact of using game elements. This contribution describes a concept for systematically analysing the group-specific effects of different game mechanics on mobility decision processes (e.g. mode and route choice. Based on theoretical findings concerning player types and mobility styles we developed a framework for identifying effective game mechanics motivating users to explore mobility alternatives and take more informed and more sustainable mode or route choice decisions. The results will form the basis for implementing game mechanics in mobility information services motivating users to explore unfamiliar but more sustainable mobility options.

    Buyer power and asset specificity are important factors of affecting technological innovation in vertical market.Taking Chinese automobile industry statistics from 2000 to 2008 as samples,this paper empirically tests the relationship between buyer power,asset specificity and technological innovation through the panel data model.The results show that technological innovation depends not only on supplier market conditions,but also on the competitive conditions of downstream industry.Buyer market power helps promote upstream technological innovation activities;buyer asset specificity has a significant negative effect on their own technological innovation,the higher the proportion of fixed assets is,the less RD inputs will be.In addition,buyer technological capabilities and the rapid growth of market demand have a positive impact on technological innovation,while equal market power between upstream and downstream industries is an obstacle to technological innovation.%在纵向关联市场中,买方势力和资产专用性是影响企业技术创新的重要因素。本文以我国汽车工业2000-2008年统计数据为样本,利用面板数据模型对买方市场势力、资产专用性与技术创新的关系进行了实证检验,研究结果表明:技术创新行为不仅取决于企业自身所处的市场条件,还与作为买方的下游行业市场竞争状况有关,买方市场势力的增强有利于上游企业技术创新活动的开展;下游企业的资产专用性对上游企业技术创新具有显著的负效应,固定资产比例越高,研发投入越少。此外,较快的市场需求增长率和买方技术能力对技术创新具有积极影响,上下游行业之间较为对等的市场势力会阻碍技术创新。

  17. Flasher Powered by Photovoltaic Cells and Ultracapacitors

    Science.gov (United States)

    Eichenberg, Dennis J.; Soltis, Richard F.

    2003-01-01

    A unique safety flasher powered by photovoltaic cells and ultracapacitors has been developed. Safety flashers are used wherever there are needs to mark actually or potentially hazardous locations. Examples of such locations include construction sites, highway work sites, and locations of hazardous operations. Heretofore, safety flashers have been powered by batteries, the use of which entails several disadvantages: Batteries must be kept adequately charged, and must not be allowed to become completely discharged. Batteries have rather short cycle lives, and their internal constituents that react chemically to generate electricity deteriorate (and hence power-generating capacities decrease) over time. The performances of batteries are very poor at low temperatures, which often occur in the circumstances in which safety flashers are most needed. The disposal of batteries poses a threat to the environment. The development of the present photovoltaic/ultracapacitor- powered safety flasher, in which the ultracapacitors are used to store energy, overcomes the aforementioned disadvantages of using batteries to store energy. The ultracapacitors in this flasher are electrochemical units that have extremely high volumetric capacitances because they contain large-surface-area electrodes separated by very small gaps. Ultracapacitors have extremely long cycle lives, as compared to batteries; consequently, it will never be necessary to replace the ultracapacitors in the safety flasher. The reliability of the flasher is correspondingly increased, and the life-of-system cost and the adverse environmental effects of the flasher are correspondingly reduced. Moreover, ultracapacitors have excellent low-temperature characteristics, are maintenance-free, and provide consistent performance over time.

    Concerning the above, it is discussed whether such a system is feasible in Japan. A zinc/air cell system requires some special plants for zinc regeneration, etc. It is necessary to build a zinc refining plant and to install dozens of electrode replacing facilities in an area dozens of kilometers in diameter with the plant at the center. For such a system to be functional, there have to be several tens of thousands of automobile users in a limited area. In Japan, so large a number will not be found anywhere even if the appeal is directed to those in the postal service and electric utilities. There will be no economic success in Japan, different from in Germany. As for the economic comparison between a zinc/air cell system and natural gas system, the two will be equivalent to each other as far as the use of the quick filling stations for the natural gas automobiles remains as it is. When the number in consideration is so large as several tens of thousands, however, the natural gas system will turn out to be economically superior to the zinc/air cell system. 19 figs., 29 tabs.

  2. Power transformer protection by using Fuzzy Logic

    Directory of Open Access Journals (Sweden)

    A. Aziz

    2009-01-01

    Full Text Available Power transformer protective relay should block the tripping during magnetizing inrush and rapidly operate the tripping during internal faults. Recently, the frequency environment of power system has been made more complicated and the quantity of 2nd frequency component in inrush state has been decreased because of the improvement of core steel. And then, traditional approaches will likely be maloperated in the case of magnetizing inrush with low second harmonic component and internal faults with high second harmonic component. This paper proposes a new relaying algorithm to enhance the fault detection sensitivities of conventional techniques by using a fuzzy logic approach. The proposed fuzzy-based relaying algorithm consists of flux-differential current derivative curve, harmonic restraint, and percentage differential characteristic curve. The proposed relaying was tested with MATLAB simulation software and showed a fast and accurate trip operation

  4. Projections of automobile ownership and use based on household lifestyle factors. [To year 2025

    Energy Technology Data Exchange (ETDEWEB)

    1979-03-01

    This report projects to the year 2025 the total number of automobiles that would be owned by American households, (total ownership) and the total number of miles that these vehicles would be driven per day (total use) given certain assumptions about the future of U.S. society. These assumptions relate to demographic, economic, and geographical attrributes of U.S. society that are relevant to the automobile. The impacts of these assumptions were analyzed via a set of projection models which explicitly recognize the relationship between these particular attributes of society and the automobile. Part I presents an overivew of the research and Part II the results. The methodology used to generate the projections is discussed in some detail in Part III. In a base case projection the number of automobiles and average daily travel of Americans double by 2025 due to increases in populaion, headship rates (households per population), and incomes. economic variables account for about half of this increase as indicated by a no economic growth projection in which ownership and daily travel increase just over 40% and 50%, respectively. Other projections explore the effects of differing assumptions regarding rates of household formations, population growth, and income growth. Model projections suggest that changed work schedules and the re-emergence of cities as growth areas will have only slight impacts on future travel and vehicle ownership.

    Previous studies independently showed that acute treatment with a selective serotonin reuptake inhibitor (SSRI) enhanced happy face recognition, and dominance behaviors which might reflect enhancement of reward sensitivity. The present study aimed to determine whether such a mechanism would be related to social resource acquisition induced by an SSRI. Forty healthy subjects were recruited for the experiment. A randomized, double-blind, placebo-controlled crossover nested within confederate type (happy, fearful, or sad) trial of a single-dose of 10mg escitalopram versus placebo was conducted with a two-week washout period. In each of the treatment groups, the subjects interacted socially with one of the three types of confederate in a waiting room for 3-minute. Then, they went to an individual laboratory and were led to believe that they played the Mixed-motive game with the confederate. The game measures punitive/cooperative behaviors by how participants allocate higher/lower game scores to the confederate and communicate cooperation/ingratiation/helplessness/sadness/blaming/extrapunitive, messages to the confederate. Significant treatment-by-confederate type interactions were observed through game score distributions and ingratiation messages to the confederate and attentive eye gaze. In the happy confederate condition, escitalopram increased ingratiation messages and lowered points awarded to the confederate. In the fearful confederate condition, escitalopram increased ingratiation messages and reduced time spent looking away from the confederate. No changes in these measures were found in the sad confederate condition. Therefore acute escitalopram treatment enhances reward sensitivity to the facial emotions of social partners which in turn increases social resource acquisition and social dominance towards happy but not fearful social partners.

    2015-01-01

    Controller area networks (CANs) have been designed for multiplexing communication between electronic control units (ECUs) in vehicles and many high-level industrial control applications. When a CAN bus is overloaded by a large number of ECUs connected to it, both the waiting time and the error probability of the data transmission are increased. Thus, it is desirable to reduce the CAN frame length, since the duration of data transmission is proportional to the frame length. In this paper, we present a CAN message compression method to reduce the CAN frame length. Experimental results indicate that CAN transmission data can be compressed by up to 81.06%with the proposed method. By using an embedded test board, we show that 64-bit engine management system (EMS) CAN data compression can be performed within 0.16 ms;consequently, the proposed algorithm can be successfully used in automobile applications.

    Full Text Available This paper endeavors to present a classification, review and analysis of the literature on Plant Maintenance Management Practices (PMMP employed in Automobile Industries. There is a considerable amount of published research available concerning plant maintenance during the last few decades. Similarly many research articles are available which focuses on various aspects of automobile industries. However, very few studies focus on critical examination of maintenance practices in Automobile Industries in particular. Hence considering the slump in automobile industries in the recent times, a wide-ranging and focused review is attempted here and only those researches have been examined which mainly concentrates on this core aspect. Thus one of the objectives of this literature review is to investigate the present state of Plant Maintenance Management Practices, based on studies conducted in different countries and published in a variety of journals over the past two decades. An examination of 55 pertinent research studies have shown that the publications can be grouped in two categories namely Conceptual and Empirical Research. An analysis of these research articles published between 1990 and 2008, revealed that current maintenance practices ranges from conventional to the latest techniques for optimizing maintenance function like TPM, RCM and Proactive Maintenance. These studies focused more on maintenance problem solving and the main difficulties are reported along with probable solutions. Another goal of the paper is to analyze the articles by year and type of journal they were published in, to determine the trends in maintenance management studies and recommend future direction for research.

    Full Text Available The aim of the paper is to present a three dimensional transient cooling analysis of an automobile cabin with a virtual manikin under solar radiation. In the numerical simulations the velocity and the temperature distributions in the automobile cabin as well as around the human body surfaces were computed during transient cooling period. The surface-to-surface radiation model was used for calculations of radiation heat transfer between the interior surfaces of the automobile cabin and a solar load model that can be used to calculate radiation effects from the sun's rays that enter from the glazing surfaces of the cabin was used for solar radiation effects. Inhomogeneous air flow and non-uniform temperature distributions were obtained in the automobile cabin and, especially in ten minutes of cooling period, high temperature gradients were computed and measured and high temperature values were obtained for the surfaces which were more affected from the sunlight. Validations of the numerical results were performed by comparing numerical data with the experimental data presented in this study. It is shown that the numerical results were good agreement with the experimental data.

    As point cloud of one whole vehicle body has the traits of large geometric dimension, huge data and rigorous reverse precision, one pretreatment algorithm on automobile body point cloud is put forward. The basic idea of the registration algorithm based on the skeleton points is to construct the skeleton points of the whole vehicle model and the mark points of the separate point cloud, to search the mapped relationship between skeleton points and mark points using congruence triangle method and to match the whole vehicle point cloud using the improved iterative closed point (ICP) algorithm. The data reduction algorithm, based on average square root of distance, condenses data by three steps, Computing datasets' average square root of distance in sampling cube grid, sorting order according to the value computed from the first step, choosing sampling percentage. The accuracy of the two algorithms above is proved by a registration and reduction example of whole vehicle point cloud of a certain light truck.

  4. Motive of the Predetermined Duel in Novels by Balzac, Lermontov and Dostoevsky

    Directory of Open Access Journals (Sweden)

    Nazirov R. G.

    2014-01-01

    Full Text Available The article introduces to the domestic reader an unknown French work of Romain Nazirov titled “Trois duels (Balzac, Lermontov, Dostoievski”. Nazirov compares the variations of the theme “barren omnipotence” in the novel “The magic skin”, “A Hero of Our Time” and “Demons”, considering the episode of “predetermined duel” as the climax of the of the theme development. Comparative analysis gives the author a reason to believe that Lermontov describing duel in the “Hero of Our Time” was under the influence of a similar episode of the novel “The magic skin” by Balzac. However, according Nazirov, in the novel by Lermontov duel becomes a philosophical experiment of the hero. This observation naturally leads the author to Dostoevsky’s novels in which such experiments directly determine the fate of tragic ideologists, the central figures of these texts. Stavrogin’s duel Nazirov interprets as a result of creative debate of Dostoevsky with Balzac and Lermontov. “The magic skin” and “A Hero of Our Time” emphasized the inability to find a goal worthy of omnipotence of hero. “Demons” accentuate the motive of personal guilt, which renders meaningless all further goals and actions of the hero. However Nazirov’s interpretation of “Demons” is determined not only by moral issues. For the soviet literary scholarship in 1970s social the context of moral conflict of “Demons” is also important. This context defined by process of breakdown of traditional Russian society structures during the second half of the XIX century. Thus, the article presents a historical and literary-historical comment of the topic “barren omnipotence” of Balzac to Dostoevsky. In this work, there are all the typical characteristics of a mature scientific style of Nazirov: attention to the social aspects of the history of literature, historical approach to the actual literary phenomena, moral sharpening of artistic perspective.

  5. How to motivate your problem people.

    Nicholson, Nigel

    2003-01-01

    Managers who motivate with incentives and the power of their vision and passion succeed only in energizing employees who want to be motivated. So how do you motivate intractable employees--the ones who never do what you want and also take up all your time? According to Nigel Nicholson, you can't: Individuals must motivated themselves. Nicholson advocates a method that turns conventional approaches to motivation upside down. Instead of pushing solutions on problem employees, the manager should pull solutions out of them by creating circumstances in which the employees can channel their motivation toward achievable goals. That means addressing any obstacles-possibly even the manager's own demotivating style--that might be hindering the employees. The author's method demands that a manager take charge of a difficult situation and resolve it. An investment of time is required, but it will bring the manager to a resolution sooner than other means would. Using detailed examples, Nicholson walks the reader through his method, pointing out potential pitfalls along the way. First, the manager creates a rich picture of the problem person. Second, the manager exercises flexibility and reframes goals so that the employee can meet them. Third, in a carefully staged, face-to-face conversation, the manager meets with the problem employee on neutral ground. Whether a problem is solved or simply resolved, the payoffs from using this method extend beyond the specific employees who have been difficult to motivate. Besides increasing a manager's chances of motivation problem people, the method can inspire an entire team by signaling that the organization deals with difficult people rather than discarding them.

    Full Text Available Online courses taught using a learning management system are common in higher education. Teaching online requires a new set of skills, knowledge, and professional growth. Faculty development programs often overlook factors that promote or inhibit the use of technologies among professors. This study identified the motivation factors that faculty consider relevant to their personal decision to adopt a learning management system. A needs assessment evaluation methodology was applied to investigate two research questions. The first question analyzed the demographics of the participants in this study including gender, age, tenure status, department, and years of experience using a technology and using an LMS. The second research question investigated the intrinsic and extrinsic factors that motivate faculty to adopt a learning management system in their instruction. Participants (N = 42 were tenured and tenure track faculty instructing at a four-year public university in California.

    Full Text Available I observed that students from Barranquillita public school had a great lack of motivation, low interest in learning English and they did not like to interact in English class. They presumed that they could not learn a second language and it was not useful for them because they only wanted to finish school in order to go to work. In view of this, I considered it necessary to know my students´needs, likes, learning styles, preferences and dislikes better in order to design activities that would motivate their interest to learn English. Taking into account this issue, I decided to give my students the possibility to have contact and experience in the English language in order to increase their communicative competence.

    Fontela, Pablo; Soria, Antonio; Mielgo, Javier; Sierra, José Francisco; de Blas, Juan; Gauchia, Lucia; Martínez, Juan M.

    Nowadays, new technologies and breakthroughs in the field of energy efficiency, alternative fuels and added-value electronics are leading to bigger, more sustainable and green thinking applications. Within the Automotive Industry, there is a clear declaration of commitment with the environment and natural resources. The presence of passenger vehicles of hybrid architecture, public transport powered by cleaner fuels, non-aggressive utility vehicles and an encouraging social awareness, are bringing to light a new scenario where conventional and advanced solutions will be in force. This paper presents the evolution of an airport cargo vehicle from battery-based propulsion to a hybrid power unit based on fuel cell, cutting edge batteries and hydrogen as a fuel. Some years back, IBERIA (Major Airline operating in Spain) decided to initiate the replacement of its diesel fleet for battery ones, aiming at a reduction in terms of contamination and noise in the surrounding environment. Unfortunately, due to extreme operating conditions in airports (ambient temperature, intensive use, dirtiness, …), batteries suffered a very severe degradation, which took its toll in terms of autonomy. This reduction in terms of autonomy together with the long battery recharge time made the intensive use of this fleet impractical in everyday demanding conditions.

The results show that as much as 18 kW power could be generated by the power cycle. This would be considerable amount of power especially if compared with the engine brake power.

  8. Why achievement motivation predicts success in business but failure in politics: the importance of personal control.

    Science.gov (United States)

    Winter, David G

    2010-12-01

    Several decades of research have established that implicit achievement motivation (n Achievement) is associated with success in business, particularly in entrepreneurial or sales roles. However, several political psychology studies have shown that achievement motivation is not associated with success in politics; rather, implicit power motivation often predicts political success. Having versus lacking control may be a key difference between business and politics. Case studies suggest that achievement-motivated U.S. presidents and other world leaders often become frustrated and thereby fail because of lack of control, whereas power-motivated presidents develop ways to work with this inherent feature of politics. A reevaluation of previous research suggests that, in fact, relationships between achievement motivation and business success only occur when control is high. The theme of control is also prominent in the development of achievement motivation. Cross-national data are also consistent with this analysis: In democratic industrialized countries, national levels of achievement motivation are associated with strong executive control. In countries with low opportunity for education (thus fewer opportunities to develop a sense of personal control), achievement motivation is associated with internal violence. Many of these manifestations of frustrated achievement motivation in politics resemble authoritarianism. This conclusion is tested by data from a longitudinal study of 113 male college students, showing that high initial achievement motivation combined with frustrated desires for control is related to increases in authoritarianism (F-scale scores) during the college years. Implications for the psychology of leadership and practical politics are discussed.

    2000-01-01

    This study was conducted to determine the level of automobile window tint that causes a significant reduction of vision for automobile drivers. Contrast sensitivity was measured on 20 participants, of whom 10 were age 20 to 29 years and 10 were age 60 to 69 years, through a stock automobile window (control) and two windows darkened with plastic film. For the younger drivers, a car window with 37% transmittance did not significantly reduce contrast sensitivity, but a darker tint of 18% transmittance reduced contrast sensitivity at higher spatial frequencies. For the older drivers, a tint of 37% transmittance significantly reduced mid-to- high spatial frequency contrast sensitivity. The typical state standard (no tint with less than 35% transmittance) would thus seem to be appropriate for younger drivers; however, further examination of the standard may be necessary in regard to older drivers. Actual or potential applications of this research include guidelines and regulations regarding tinting of automobile windows. PMID:11022888

The prerequisite for modern policy making is attention to the elements of modern library management. Librarians, library managers and directors of libraries should create a work environment providing long term satisfaction with work by means of certain knowledge and tools. The level of motivation of the staff is influenced by the so called higher factors deriving from the work process itself and related to work contents: achieve¬ment, recognition, trust and work itself. Extrinsic factors (income, interpersonal relations, technology of administration, company policy, working conditions, work con¬trol, personal security, job security and position... should exercise lesser impact on the level of motivation.

    Full Text Available This article aims to identi fy the motivations behind g lobal s ourcing (GS adoption , the associated risks and barriers , and the results that companies from emerging countries are achieving . The research explores the distinguishing features of these companies ' experience and examines established theories about GS that are based on companies from developed countries. In the article, a case - based study investigat ed four companies from the electrical and electronics industry in South Brazil. Data w ere collected through in - dep th interviews , documents , and direct observation. According to the research, t he main motivations for adopting GS are faster access to new technologies and establish ing a presence in global markets. It was also found that the opportunity to offer diversified products u sing the distribution channels already developed by companies motivate s GS adoption , a situation that prior literature has not identified . Despite the risks, t he absence of a broad local supply - base prompts companies to adopt GS. Further, the failure to fo rmalize barrier analysis processes creates difficulties f or companies . Th e main results associated with GS relate to innovation and reductions in the time taken to develop product s and reach market s . In this regard, c ompanies face a challenge to develop th e abilities required to compete for the advantages that t he global market can offer.

  17. To Survive and Thrive: A Self-Determination Perspective of Political Motivation

    Political scientists concentrate on the concept of political activity as social cooperation motivated to meet two goals: biological survival and accumulation of extrinsic rewards such as power, wealth, or territory. Self-determination research in the field of human motivation reveals a different motivator in the form of innate psychological needs. This literature review and theoretical analysis offers an alternative cause for political activity in light of recent empirical work completed by p...

    The role of motivation in language learning has been studied since the 1960s. It is indeed one of the most important areas of linguistics. This paper suggests strategies of motivating language learners and focuses on the role which motivation can play in language learning. The concept of motivation from different points of view is defined, a number of suggestions on how to motivate language learners are presented and the role of motivation based on various motivational theories are highlighted. With regard to the role of motivation in language learning, it is concluded that motivation plays an increasingly important role in many aspects, such as identifying with the target language society, achieving long-term and short-term goals, improving language learners' internal and external powers and exerting a group force. It also indicates that there should be more research areas to be examined and a long way is probably requlred to go in future theoretical and practical study.

    Action selection is extremely important, particularly when the accomplishment of competitive tasks may require access to limited motor resources. The spontaneous exploration of the world plays a fundamental role in the development of this capacity, providing subjects with an increasingly diverse set of opportunities to acquire, practice and refine the understanding of action-outcome connection. The computational modeling literature proposed a number of specific mechanisms for autonomous agents to discover and target interesting outcomes: intrinsic motivations hold a central importance among those mechanisms. Unfortunately, the study of the acquisition of action-outcome relation was mostly carried out with experiments involving extrinsic tasks, either based on rewards or on predefined task goals. This work presents a new experimental paradigm to study the effect of intrinsic motivation on action-outcome relation learning and action selection during free exploration of the world. Three- and four-year-old children were observed during the free exploration of a new toy: half of them were allowed to develop the knowledge concerning its functioning; the other half were not allowed to learn anything. The knowledge acquired during the free exploration of the toy was subsequently assessed and compared. PMID:24691755

    A method of power transmission using a laser beam for a very long distance has been proposed. A compact and high power TEA CO_2 laser has been developed and it has been applied to the plasma production for the power transmission. The characteristics of the direct energy conversion from laser energy to electricity with laser-produced plasma are reported here. It is found that the total conversion efficiency increases with laser output using a carbon target. The effect of surface magnetic confi...
