Post-punching resistance of connections between flat slabs and interior columns

The paper reports tests designed to study the improvement in the post-punching resistance of slab–column connections by the provision of bottom bars passing through the columns and anchored in the slab. A series of model tests on slabs was used to developan expression for the strength limit governed by the slab concrete, while large-scale tests on abbreviated specimens were used to formulate the criterion dependent on the failure of the reinforcement. It is demonstrated that bottom reinforcement can be of significant benefit and that the resistance given by it can be assessed with reasonable accuracy.
Fast and Precise Positioning Using LMI-Based Command Shaping Considering Stand Vibration Suppression

This paper proposes an LMI-based design approach for command shaping in the fast and precise positioning control of industrial table drive systems on machine stand. In the command shaping, the position response time and the vibration suppression of machine stand can be directly considered as the constraint conditions in LMI design frame work. Fig. 1 shows a block diagram of proposed 2degrees-of-freedom robust positioning system with the LMI-based position reference, where u∗: feedforward thrust reference designed by the proposed LMI approach, Pc: nominal plant model, r: position reference, y: table displacement, and DOB is a disturbance observer with its estimation ̂ d. In this command shaping, u∗ can be shaped considering the response step number N in reference, the saturation in control input u[k], and the vibration suppression in machine stand displacement ys[k], by using the following constraints in the LMI design approach:
Psikoanalisis Sigmund Freud dan Implikasinya dalam Pendidikan

Teori psikoanalisis merupakan teori yang berusaha untuk menjelaskan tentang hakikat dan perkembangan kepribadian manusia. Unsur-unsur yang diutamakan dalam teori ini adalah motivasi, emosi dan aspek-aspek internal lainnya. Teori ini mengasumsikan bahwa kepribadian berkembang ketika terjadi konflik-konflik dari aspek-aspek psikologis tersebut, yang pada umumnya terjadi pada anak-anak atau usia dini. Psikoanalisis memiliki banyak hal untuk ditawarkan kepada pendidikan. Hubungan di antara mereka seperti sebuah perkawinan di mana kedua pasangan sadar akan kebutuhan bersama mereka, tapi tidak terlalu mengerti satu sama lain dan karena juga tidak mengerti akan namanya menyatu. Jadi tujuan-tujuan pendidikan yang dinyatakan berdasarkan analisis psikoanalisis adalah memberi tuntunan bagi pendidik dan anak didik tentang apa yang hendak dicapai, kegiatan-kegiatan yang mereka lakukan, dan tentang kemajuan yang dicapai oleh anak didik.
Multiple Switching Patterns for SHEPWM Inverters Using Differential Evolution Algorithms

An investigation on multiple patterns for both odd and even number of switching angles in a three-phase selective harmonic elimination pulse width modulation (SHEPWM) inverter is presented. The switching patterns are eand classified on the basis of the harmonic performance of the waveforms output from the inverter. Differen tial evolution algorithms are employed to calculate the optimum switching angl es. Selected cases are verified experimentally by a digital signal processorbased hardware implementation. The experimental res ults show that all types of the patterns offer low ha rmonic distortions on the inverter output after filtering. However, one tgives better harmonic performance is identified .
Reactions to Nepotism in the Hiring Process: The Role of Family Member Qualifications

This study examined whether applicant qualifications influences the reactions of others to the practice of nepotism. Business students reviewed materials describing three job applicants and then completed a questionnaire assessing their reactions to the hiring process. Results showed that, regardless of how qualified the hired applicant was, those who observed nepotism expected to have lower job satisfaction, organizational commitment and motivation than those who did not, and that the nepotism applicant was perceived as being less competent and likeable than the non-nepotism applicant. Additionally, results showed that perceptions of fairness mediate the relationship between hiring method and reactions of non-beneficiaries.
Applying a Structured Dispersion Parameter to Multiclass Stochastic User Equilibrium Assignment Model

In recent practical transportation planning in Japan, the adoption of stochastic user equilibrium assignment models for traffic assessment has been discussed. Such models include a dispersion parameter that accounts for drivers' errors in perception of travel time at the time of route choice decision. In practice, setting a rational value for this parameter is an issue. Generally, the dispersion parameter is exogenously set to the same value for all origin–destination (O-D) pairs. However, it is not guaranteed that errors in drivers' perception of travel costs are equal for all O-D pairs. This study examines how the parameter is set and applies a multiclass stochastic user equilibrium assignment model to consider differences in drivers' errors in perception of travel costs in using an existing generalpurpose road network. Results show that changes in the dispersion parameter affect the user class flows that make up the link flows rather than the link flows themselves. Setting a dispersion parameter according to the travel cost of an O-D pair rather than setting a constant parameter improves the reproducibility of the user class flows on each link. These findings encourage practical transportation planners to evaluate qualitative measures of traffic flows in the road network, such as the utilization of road links.
Assessment of different representations of spatial variability on SWAT model performance.

River basin management requires a spatially distributed representation of basin hydrology and nutrient transport processes. To accomplish this, the Soil and Water Assessment Tool (SWAT) watershed model was enhanced to simulate water flow across discretized landscape units. The model structure more closely reflects the complex controls on infiltration, runoff generation, run-on, and subsurface flow without requiring large computational resources or detailed parameterization. Four landscape delineation methods were compared: lumped, hydrologic response units (HRUs) or hydrotope, catena, and grid. The lumped method using dominant soil and land use and the HRU delineation do not consider landscape position when computing runoff. The catena method routes flow across a representative catena with divide, hillslope, and valley units. The distributed method divides the watershed into cells (1 ha each) for routing. All methods were calibrated and validated for the USDA-ARS Brushy Creek watershed (17.3 km 2 ) near Riesel, Texas. The calibration results indicate that measured flow at the basin outlet is similar (daily N-S around 0.65) for all four models, or conversely, the new models (catena and grid) do as well as the existing models (lumped and HRU based) in predicting daily flow at the basin outlet. The advantage of the catena and grid models is that the impacts of spatial changes in land use and BMPs on the hillslope valley continuum can now be more realistically assessed.
Effectiveness of Desiccant Coated Regenerative Wheels from Transient Response Characteristics and Flow Channel Properties—Part I: Development of Effectiveness Equations from Transient Response Characteristics

During steady operation, regenerative wheels are subjected to cyclic step changes in inlet properties. The equation for the transient humidity step response of a desiccant coated rotary air-to-air wheel is developed from physical principles using a model similar to that used for the sensible energy or temperature response. This fully developed flow model is used to derive a characteristic moisture transfer time constant in terms of four dimensionless flow-channel desiccant-coating properties and the time duration of airflow through the wheel. Since the moisture diffusion time delays within the desiccant coating are significant for typical energy wheels and often desiccant dryer wheels, an empirical term is introduced with this time constant to account for the effects of the duration of exposure in the two types of wheels.
Low Emission LNG Fuelled Ships for Environmental Friendly Operations in Arctic Areas

Environmental restrictions now favor cleaner fuels, and Natural gas (LNG) is one of the most promising alternative fuels. Highly efficient natural gas fuelled engines have been developed since around 1990. These engines are now entering maritime applications, offering significant emission reductions, both in a local and global perspective. Using LNG as fuel reduce NOx emissions by up to 90%, SOx and particulate matter (soot) are reduced by 95–100% and CO2 emissions are reduced by up to 25%, when compared to traditional marine fuels. These emission reductions are significant contribution especially in local and regional environments. Using LNG as a clean fuel also offers a significant increase in total energy efficiency. Combining power and heat generation, natural gas fuelled engines for on-shore power generation offer a total thermal efficiency of 80–90%, depending on the waste heat recovery rate. For liquid fuels exhaust heat recovery is limited due to the sulfur content, which may cause acid corrosion. Onboard ships, LNG fuelled engines have potential to utilize waste heat to obtain significant higher thermal efficiency than their diesel engine counterpart.LNG is mainly available from fossil sources, but now also increasingly from renewable sources as bio-gas. For storing and transportation LNG is preferred as less challenging compared to high pressure CNG. On the coast of Norway a LNG distribution system is now being built, supplying a fleet of more than 40 ships. LNG is transported by special designed small LNG carriers from the production plants to a series of main terminals along the coastline. From these main terminals the LNG is distributed by trucks to the local fuelling stations, or for direct fuelling of the ships.This paper will present the basic technology and experiences from this full scale LNG fuel system. The paper will discuss local and global environmental benefits, technical solutions, safety issues, and costs issues related to the distribution system and the on-board fuel installations.Copyright © 2013 by ASME
Study on Flow Measurement of Large-Scale Low-Lift Pumping Stations with CFD Method

The measuring method of flow of large-scale low-lift pump, in which the differential pressure of two measuring points in inlet passage instead of the mean differential pressure of two specified section of inlet passage to calibrate the relationship between flow and differential pressure, is developed. The numerical simulation on differential pressure of two measuring points in inlet passage, which is took out earlier than the pump set test method, is carried out with the standard k- turbulence model and SIMPLEC algorithm. The comparison of the relationships fitted respectively with numerical simulation approach and pump set test shows that the calibration accuracy of two different ways is nearly same. The conclusion can be drawn that the calibration of the relationship between flow and differential pressure with CFD is feasible. The CFD-based flow measurement method, as a more simple and convenient way, can be applied in large-scale low-lift pumps.
Airflow modelling studies over the Isle of Arran, Scotland

A mesoscale meteorological model is applied to simulate turbulent airflow and eddy shedding over the Isle of Arran, SW Scotland, UK. Under conditions of NW flow, the mountain ridge of Kintyre, located upwind of Arran, induces gravity waves that also affect the airflow over the island. The possibility to nest domains allows description of the airflow over Arran with a very high resolution grid, while also including the effects of the surrounding mainland of Scotland, in particular of the mountain ridge of Kintyre. Initialised with a stably stratified NW flow, the mesoscale model simulates quasi-stationary gravity waves over the island induced by Kintyre. Embedded in the larger scale wave trains there is continuous development of small-scale transient eddies, created at the Arran hill tops, that move downstream through the stationary wave field. Although the transient eddies are more frequently simulated on the northern island where the terrain is more pronounced, they are also produced over Tighvein, a hill of 458 m on the southern island where measurements of surface pressure and 2 m meteorological variables have been recorded at intermittent intervals between 1996 and 2000. Comparison between early observations and simulations so far show qualitatively good agreement. Overall the computations demonstrate that turbulent flow can be modelled with a horizontal resolution of 70 m, and describe turbulent eddy structure on wavelength of only a few hundred metres.
Temperature estimation of cooking vessel content via EKF and sliding mode observers in induction cooking systems

Abstract The problem of estimating the thermal state of an induction cooking system is analyzed. The first step is to model the thermal system composed by the cooktop, the pot, and the pot content. Then, by relying on the formulated model, the aim is to design a suitable state observer, so that an estimation of the temperature of the cooking vessel content can be made online. Two kinds of observers are proposed. An Extended Kalman Filter (EKF) and a Sliding Mode Observer (SMO). A comparison of the performances which can be obtained with these two solutions is then made by relying on experimental results obtained on a real induction cooktop heating a pot containing a certain quantity of water.
Probability of Midair Collision During Ultra Closely Spaced Parallel Approaches

This research considers the technological components required in an aircraft to safely perform simultaneous, instrument approaches into an airport with parallel runways spaced less than 2500 ft apart. Monte Carlo simulations were used in order to assess the probability of collision during an unexpected aircraft blunder, but many of the input parameters such as e ight technical error, navigation sensor error, and pilot time delay were based on recently generated experimental data. This analysis shows that with the Federal Aviation Administration’ s global positioning system-based Local Area Augmentation System operational and a reliable data link transmitting full state information between aircraft, it is technically feasible to reduce runway spacing to 1500 ft or less using the same safety criteria as that used for the recently implemented Precision Runway Monitor program.
Design study of part-flow evaporative gas turbine cycles : Performance and equipment sizing - Part II: Industrial core

This is Part II of a two-part paper and presents calculation results of a part-flow EvGT cycle based on gas turbine data for the ABB GTX100 (modified for intercooling). The evaporative gas turbine cycle is a new high-efficiency cycle that has reached the pilot testing stage. This paper presents calculation results of a new humidification strategy based on part-flow humidification. This strategy involves using only a fraction of the compressed air for humidification. Thermodynamically, it can be shown that not all the air needs to be passed through the humidification system to attain the intrinsic good flue gas heat recovery of an EvGT cycle. The presented system also includes live steam production arid superheating, by heat from the hottest flue gas region, for injection. The humidifier then only uses the lower temperature levels, where it is best suited. The analyzed system is based on data for the ABB GTX100.gas turbine in intercooled mode. Part 1 of this two-part paper presents the results based on data for the aeroderovative Rolls Royce Trent. Simulation results include electric efficiency and other process data as function of degree of part flow. A detailed model of the humidifier is used, which produces sizing results both for column height and diameter Paper I includes detailed description of the modeling. For the GIX100 system, full-flow humidification generates an electric efficiency of 52.6% (simple cycle 36.2%). The efficiency is virtually unaffected if the air portion to humidification is cut to 60% of accessible compressor air (represents 48% of compressor intake). If 30% of air from the compressor after cooling bleed (24% of intake) is led to the humidifier, the efficiency is reduced to 52.2%. On the other hand is the total heat exchanger area reduced by 20% and column volume by 50%. This calls for a recommendation not to use all the compressed air for humidification. It is recommended to use 15-30% of compressor intake air. The exact economic optimum depends on local fuel prices, CO 2 taxes, interest rates, etc.
Technology Options for Distance-Based Road User Charging Schemes

Road user charging schemes have great potential to reduce congestion and negative environmental effects. Moreover, implemented schemes are viewed as successful. Nevertheless, only a few road user charging schemes have been implemented worldwide, and they are all limited in nature. Currently, several countries are planning to implement road user charging schemes that are more ambitious in terms of geographical scale (nationwide), scope (all vehicle types) and level of differentiation (to distance, time and place). However, implementation is a cumbersome process. The technology choice is moreover a key barrier in this process, owing to the complexity of the task: technology options for road use measurement, data communication, and enforcement and inspection. To facilitate technology choices and contribute to the literature on road user charging technologies, this paper 1) describes the functional architecture, including the road user charging scheme subsystems; 2) classifies the available technologies and updates a survey of the (rapidly developing) technologies; 3) gives a comprehensive overview of appraisal criteria for technology choices; and 4) discusses the main technology-related trade-offs and synergies in terms of the functional architecture. The optimal technology option is a package of technologies that should be selected from a systems perspective, including all functional requirements, objectives, trade-offs (e.g. accurateness versus cost components) and synergies (e.g. technologies using the same infrastructure), and be flexible enough to cope with future adaptations.
Learning by ostentation for robotic assembly

A machine-learning technique is used to enable a robot, consisting of a vision system and a manipulator arm, to learn by observation, and then perform, a variety of block-stacking assembly operations. The robot can perform these tasks in spite of variation of the initial locations of the blocks, imprecision in its movements, and initial uncertainty about its camera location and arm geometry. Important aspects of this work are how continuous phenomena are perceived and mapped into discrete representations, and how the arm and camera are coordinated with each other.
Translational Research: From Biological Discovery to Public Benefit (or Not)

Advances in biology are occurring at a breathtaking pace today, from genetic insights facilitated by the Human Genome Project and next generation DNA sequencing technologies, to global nucleic acid and proteomic expression measurement using new high-throughput methods. Less publicized in recent years, yet still the central driver of progress, are the steadily proceeding biological insights gained through tried and true hypothesis-driven investigation into the complex worlds of metabolism, growth, development, and regulation. Certainly, the basic science ecosystem is productive and this portends well for the myriad new applications that will benefit mankind; drugs, vaccines, devices, and related economic growth—or perhaps not—in stark contrast to the generation of fundamental biological knowledge are inefficiencies in applying this information to real-world problems, especially those of the clinic. While investigation hums along at light speed, translation often does not. The good news is that obstacles to progress are tractable. The bad news, however, is that these problems are difficult. The present paper examines translational research from multiple perspectives, beginning with a historical account and proceeding to the current state of the art. Included are descriptions of successes and challenges, along with conjecture on how the field may need to evolve in the future.
Initial operating experiences of a nutrient removal process (Modified Bardenpho) at Kelowna, British Columbia'

A new wastewater treatment plant that utilizes the “Modified Bardenpho” process for nutrient removal has recently been commissioned in Kelowna, B.C. The 260 L/s facility (130 L/s in each of two parallel modules) has been operating at full design flow through one module for over 6 months.Two months of operating time was required to establish the nitrification–denitrification capabilities and to build up the phosphorus release–uptake mechanism in the biomass. Subsequent to that start-up period, the process has been capable of producing an effluent containing less than 5 mg/L total nitrogen and less than 0.3 mg/L orthophosphate when the influent sewage has contained some 30 mg/L of nitrogen and 6 mg/L of phosphorus. Key words: phosphorus removal, nitrogen removal, biological waste treatment, advanced waste treatment.
A Clutter Suppression Algorithm for GPR Data Based on PCA Combining with Gradient Magnitude

Ground penetrating radar (GPR) is a powerful tool for detecting defects behind reinforced concrete (RC) structures. However, the received data from GPR includes a large number of clutters which are easy overwhelming the signal of target. In order to successfully extract the target signature, these clutters effects need to be eliminated. In this article, a clutter suppression algorithm based on Principal Component Analysis (PCA) combining with gradient magnitude is presented. PCA clutter suppression algorithm is applied to the data and removes most of the echoes from ground surface and portion of other clutters with weak energy. Then gradient magnitude clutter suppression is used to remove majority of the residue clutters. It is demonstrated from simulation that the proposed algorithm is able to significantly suppress the clutters and is superior to the PCA clutter suppression, magnitude clutter suppression and means subtraction method.
