Compaction of Soil Treated With Municipal Solid Waste Compost Using Low-Pressure and Traditional Tyres

Abstract Results from a 3-year experiment carried out to detect the consequences of using municipal solid waste compost (MSW) in agriculture are reported. To assess the persistence of its effects in time, the compost was spread only in the first year. In particular, the effect of the compost upon top soil compaction caused by a wheeled-tractor equipped with traditional and low pressure tyres was considered. It was found that soil treated with compost was less compactable than normal soil and that this effect lasted into the third year. However, the lower bulk density in undisturbed soil resulting from the compost diminishes with time. The lower compaction achieved using low-pressure tyres occurred only after the first pass of the tractor; after the second pass, compaction was practically the same as with conventional tyres. Crop yield was reduced by the application of compost and this decrease arose in the first year. No significant difference in yield resulted from the use of the low-pressure tyres, apart from some trend towards higher production in the second and third year in less compacted soil.
FOREIGN PARTICIPATION IN THE SHARE CAPITAL OF COMPANIES IN ROMANIA – A REGIONAL ANALYSIS

There is a broad consensus in the field literature regarding the positive effects of foreign investments in the economy at the national and regional level. Foreign investments are considered an engine of economic development, a sine qua non condition for the general wellbeeing, especially in countries involved in catching up process. When we refer to regions, we can not overlook the existing disparities. Interregional disparities exist also in terms of foreign investments attracted. In this paper, after presenting some economic indicators that outlined the level of development of the regions, it was conducted an analysis of the distribution and evolution of the the value of subscribed capital and of the number of companies with foreign participation in the share capital registered in Romania, by development regions. During the analyzed period, 2001-2019, there was an upward trend in all the development regions in terms of the value of subscribed capital in companies with foreign participation. However, the difference between the Bucharest-Ilfov region and the rest of the regions is striking. The results showed that Bucharest-Ilfov region attracted the most in what concerns foreign investment. More than half of the foreign participations in the share capital were made in this region. The second position, in terms of the value of subscribed capital, is occupied by the Center region and the third by South-Muntenia region. Regarding the number of registered companies with foreign participation in the share capital, Bucharest-Ilfov region also dominates, being the most desirable region of development for the foreign investors who want to invest in Romania. West and North-West regions are placed on the second, respectively third position. South-West Oltenia development region is placed on the last place, both in terms of the number of companies registered and of the value of subscribed capital. This analysis revealed the major disparity between the Bucharest-Ilfov region and all the other development regions regarding the foreign investments attracted in the form of the participations in the social capital. This gap has accentuated during the last decade, the rhythm of growth being much higher in Bucharest-Ilfov region compared to the other development regions.
The Myth of the Superhuman Professor

Your car has been making ominous clunking sounds lately and you've brought it in for a checkup. The mechanic says there are some minor transmission problems, which he'll fix while you wait. You position yourself in the grimy lounge with the stack of four-year-old issues of Road and Track and wait. And wait. After an hour you poke your head into the garage and ask what's going on, and the mechanic tells you he's right on top of the problem and is almost finished. After two more hours you storm out and find a maze of parts scattered all around and the mechanic thumbing through a repair manual and looking perplexed. You ask him what he's doing, and he says he thinks he needs to replace the torque converter but he's not sure where it is and the diagram in the book is no help. Seriously worried now, you ask him if he's really a trained mechanic, and he says that actually he's not he's a body repairman but the shop policy is that everybody is supposed to work on everything and if you'll just have patience he'll figure it out sooner or later.and while he's got your hood up he might just have a look at a couple of valves that seem like they're about to go. You start to whimper and plead with him to put your car together and let you go.
Human Error in Maritime Operations: Analyses of Accident Reports Using the Leximancer Tool

This paper focuses on the problem of lack of Situation Awareness (SA) by mariners. An analysis of a large number of accident reports was conducted in order to determine the extent to which SA is a relevant issue in merchant shipping operations. For the first time use was made of the Leximancer tool due to its ability to rapidly analyse large amounts of textual information. One major function of this research was to examine the accuracy and usefulness of such a data analysis tool by comparing the results of this computer analysis with that of a ‘manual’ analysis (performed by two raters). Our results underline the importance of SA in decision-making processes in the maritime domain: a large number of investigated maritime accidents were partly due to loss of SA. Also, the results of the Leximancer tool were found to be comparable to the manual analysis, thus suggesting further use of such a system for accident report analysis in other transportation domains.
Measurement of Probe Angle for Ultrasound Evaluation of Articular Cartilage Using “Rise-to-Peak Time”

Background. Ultrasound evaluation of articular cartilage is not accurate if the ultrasound probe is not perpendicular to the cartilage surface. However a probe angle adjustment is difficult because of the manual procedure and the lack of angle index for the measurer. The aim of this study is to propose “Rise-to-Peak time” as an index of probe angle and to evaluate its effectiveness in evaluating articular cartilage surfaces. Methods. The “Rise-to-Peak time” is defined as the time interval between the rise of the first peak (50% amplitude of the first peak) and the first positive peak following the minimum peak of the echo. The relationship between the Rise-to-Peak time and probe angle was evaluated using several reflection surfaces including that of articular cartilage. Findings. The “Rise-to-Peak time” increased monotonically with increases in the angle between the probe and the reflection surface, and showed good agreement with calculated values for small angle changes (<3 degrees). Interpretation. The “Rise-to-Peak time” provides an index of probe angle in the ultrasound measurement of articular cartilage. Availability of echo-amplitude correction using the “Rise-to-Peak time” is evaluated.
Reliability-Based Dynamic Load Allowance for Capacity Rating of Prestressed Concrete Girder Bridges

The current highway bridge design in the United States follows the AASHTO-LRFD specifications, which prescribe a dynamic load allowance, IM, of 0.33 for the dynamic effect of truck/tandem loading. Studies have shown that the IM value prescribed by the LRFD code may underestimate this dynamic effect under poor road surface conditions (RSCs). One reason for this underestimation is that the IM value employed in the AASHTO specifications was obtained from the statistical properties of the IM relative to average RSC, as defined by the ISO 1995 standards. In addition, the IM, which is a random variable with certain statistical properties, was modeled as a deterministic constant in the code calibration process. In this paper, the reliability indexes of a selected group of prestressed concrete girder bridges, designed following the AASHTO-LRFD code, are calculated by modeling the IM explicitly as a random variable for different RSCs. It is found that although the calculated bridge reliability indexes are usually above the target reliability index value of 3.5 under above-average RSCs, they can be significantly below the target value of 3.5 when the RSCs are below average. Following the load rating procedure proposed by the AASHTO load and resistance factor rating (LRFR) manual, it is also found that the code-employed IM value may overestimate the rating factors when RSCs are below average. Based on these results, appropriate IM values are suggested for different RSCs to achieve a consistent target reliability index and a reliable load rating. The results presented in this paper are particularly valuable for the rating of existing prestressed concrete girder bridges, for which the actual RSCs can be directly evaluated. The RSCs must be properly taken into account to accurately estimate the actual safety of the considered bridge.
Consumers’ intention to visit green hotels – a goal-framing theory perspective

Abstract The theory of planned behaviour (TPB) and value-belief-norm (VBN) theory are recognised as powerful predictive models to explain consumers’ green purchase behaviour (GPB). The models were frequently used for predicting consumers’ green hotel visitations in previous studies. However, an unresolved research gap exists in green hotel literature concerning consumer attitude and behaviour in determining whether TPB or VBN possess inherent disadvantages in predicting GPB. The latest studies identified the goal-framing theory as an appropriate integrative framework to understand consumer GPB compared to the TPB and VBN. Nevertheless, only limited studies applied and tested the goal-framing theory in determining green hotel selection. This study revealed that the goal-framing theoretical framework has a higher predictive capacity than TPB and VBN in predicting consumer green hotel visit intention. The findings indicated a positive correlation between gain goal-frame, normative goal-frame, hedonic goal-frame, and intention. Furthermore, the results showed a positive relationship between subjective norm, attitude and personal norm. The results also demonstrated how consumers’ intentions are derived from gain goal-frame, normative goal-frame (except altruism), and hedonic goal-frame dimensions and how subjective norms influence attitude and personal norm. Lastly, the theoretical and practical implications and limitations were discussed.

FORMULE SEMI-EMPIRIQUE POUR LA DÉTERMINATION DE LA PRESSION EXTÉRIEURE LIMITE D'INSTABILITÉ DES CONDUITES MÉTALLIQUES LISSES NOYÉES DANS DU BÉTON

Se basant sur des notions classiques de résistance des matériaux et utilisant les résultats des essais objet de l'article précédent ainsi que d'autres plus anciens, l'auteur établit une formule pour déterminer la pression limite d'instabilité des blindages non renforcés, compte tenu des défauts de forme et du jeu entre tôle et béton. Cette formule vérifie de façon acceptable les essais récents sur 0 4 100 mm, et ceux effectués antérieurement par M. Borot sur 0 955 mm; elle permet également de calculer des courbes de contrainte en fonction de la pression qui sont en bon accord avec celles relevées au cours des essais. Des essais supplémentaire sur modèle réduit 0 200 mm confirment ces résultats et permettent de fixer des limites de validité qu'il convient de respecter en raison de la nature semi-empirique de la formule proposée. Using classical strength of materials techniques together with the results of the tests described in the previous article and the results of earlier tests, the author derived a formula for the limiting collapse pressure for unreinforced linings, which allows for shape defects and for the clearance between the concrète and the plating. This formula satisfactorily checks the récent tests on h,100 mm diameter pipes as ivell as those performed b;j Borot on 955 mm diameter pipes. It also enables stress versus pressure curves to be drawn which check well with those obtained during the tests. Further tests on a 200 mm diameter model verified the results and enabled limits to be set within which the formula could be used, this being necessarij because of its semi-empirical nature.
Assessment of Wider Economic Impacts of High-Speed Rail for Great Britain

This paper considers the scope for wider economic impacts of agglomeration-based effects in the context of high-speed rail. The paper provides new evidence concerning the distance decay of long-distance travel and on the basis of such estimates assesses the potential order of magnitude of agglomeration benefits from improvements to high-speed rail transport in Great Britain. A new methodology assumed constancy of trip decay with respect to equal average travel times but variability with respect to distance. The expected outcome was that improvement in travel times would reduce the extent to which travelers perceived distance as an obstacle to interaction. Although urban economic theory did not preclude the existence of agglomeration benefits across interregional distances, the empirical evidence suggested that the order of magnitude of agglomeration benefits corresponding to 25% and 50% increases in travel speeds was small.
Gating and Class Relations: the case of a New Delhi “colony”

During the 1990s an increasing number of New Delhi's elite neighborhoods erected gates with guards at their entrances. A process, which elsewhere has been termed fortification or gating, is unfolding in the city. In the context of changing class relations in urban India this article explores the gating of one centrally located upscale neighbourhood, or “colony,” called Golf Links in New Delhi. In Golf Links, the elite explains the gating as a result of increased crime and untrustworthy servants. In this article it is argued rather that gating must be understood in terms of complex transformations unfolding in Indian cities. The case of Golf Links provides insight into how these changes affect urban Indian class relations.
Designing user interfaces with gestures and sound. Towards the performance and appeal of voice mail browsing

This paper explores the use of sound and gestures within a tangible user interface, towards influencing the performance and appeal of browsing through a voice mail collection. Three browsers were developed, in which speech and non-speech sounds were projected in a sound-scape above a tangible interface. For each of the browsers, users were given the task of locating voice mail messages. Search behaviour in terms of gestures, task time, and errors, were recorded and categorised. Users' experience was measured in terms of appeal, consisting of hedonic and ergonomic qualities. Results showed that users' explorative behaviour changed, depending on the specific type of browser. Subjects were observed to utilise non-speech sound cues effectively in searching for target voice mail messages. Subjective results showed that ergonomic and hedonic qualities of appeal were found to interact in an averaging way, such that overall appeal was similar across conditions. Implications towards designing multimodal interfaces are discussed.
Is automated conversion of video to text a reality?

A recent trend in law enforcement has been the use of Forensic lip-readers. Criminal activities are often recorded on CCTV or other video gathering systems. Knowledge of what suspects are saying enriches the evidence gathered but lip-readers, by their own admission, are fallible so, based on long term studies of automated lip-reading, we are investigating the possibilities and limitations of applying this technique under realistic conditions. We have adopted a step-by-step approach and are developing a capability when prior video information is available for the suspect of interest. We use the terminology video-to-text (V2T) for this technique by analogy with speech-to-text (S2T) which also has applications in security and law-enforcement.
Integrated Micro-Channel Cooling in Industrial Applications

Experiments and simulations have been performed in order to assess the feasibility of integrated single phase forced convection in silicon micro-channels for the cooling of electronics. A silicon micro-channel device has been fabricated with channel size of 100 by 300 μm. Cooling has been achieved with a heater dissipating up to 370 W (750 W/cm2 ) with a flow rate of 0.1 1/min. In this case the maximum junction temperature was 130°C. This paper presents characteristics of such a cooling device as well as its description and fabrication. Experimental results are shown and compared with simulations. A description of a rough optimization of the channels size is given followed by comments describing the main advantages and drawbacks regarding industrial feasibility. © 2004 ASME
R&D, Technology Transfer and Innovation Performance: Evidence from Chinese Industries

Based on the data of large and medium-sized industrial enterprises put forward by National Bureau of Statistics of China, over the period 1991-2007, this paper empirically investigates the dynamic econometrical relationship among R&D, technology transfer, including imports of technology and purchase of domestic technology and innovation performance which is denoted by new product sales, using ADF unit root test, co-integration analysis and granger causality test. The empirical research results indicate that innovation performance is granger causing R&D and technology transfer, while R&D and technology transfer are not granger causing innovation performance. Neither the feedback effect between R&D and innovation performance nor that between technology transfer and innovation performance is occurring.
Precise estimation of linewidth reduction in wavelength-detuned DFB semiconductor lasers

The linewidth reduction of DFB semiconductor lasers due to the wavelength detuning is estimated precisely. Firstly, the Schawlow-Townes linewidth, which excludes the enhancement due to the carrier effect, is determined from the AM noise spectrum. Secondly, the actual linewidth including the carrier effect is measured. Lastly, the contribution from the carrier effect is determined from both of the linewidths. The experimental result shows that the linewidth enhancement due to the carrier effect is four times larger in a 1. 3μm laser with a positive detuning (Δλ= + 15nm) than in a laser with a negative detuning (Δλ= − 15 nm).
Boundary shear distribution in open channel compound

The importance of the determination of boundary shear distribution and the applicability of measurement by surface pitot tube technique after Preston1in open channel flow are discussed. The results of the investigation made to explore boundary shear distribution in a smooth and an artificially roughened compound channel are presented. The distribution of shear is found to be non-uniform in character and the location of maximum bed and side shear stress to be some distance from the centreline and free surface. The sharing of total drag force by the different segments of the channel section is found to be related to the depth of flow and roughness concentration.
Compressive Strength and Splitting Tensile Strength of Steel Fiber Reinforced Ultra High Strength Concrete (SFRC)

This paper investigates the compressive strength and splitting tensile strength of ultra high strength concrete containing steel fiber. The steel fibers were added at the volume fractions of 0%, 0.5%, 0.75%, 1.0% and 1.5%. The compressive strength of the steel fiber reinforced ultra high strength concrete (SFRC) reached a maximum at 0.75% volume fraction, being a 15.5% improvement over the UHSC. The splitting tensile strength of the SFRC improved with increasing the volume fraction, achieving 91.9% improvements at 1.5% volume fraction. Strength models were established to predict the compressive and splitting tensile strengths of the SFRC. The models give predictions matching the measurements. Conclusions can be drawn that the marked brittleness with low tensile strength and strain capacities of ultra high strength concrete (UHSC) can be overcome by the addition of steel fibers.
Aerodynamic Predictions, Comparisons, and Validations Using MissileLab and Missile Datcom (97)

Abstract : Aerodynamic prediction software is often used in the early stages of missile systems designed to quickly and accurately estimate the aerodynamics of a wide variety of missile configuration designs operating over many different flight regimes. It is also possible to use these empirical packages to validate flight data collected from wind tunnel tests and other open sources. Analysis of such data provides users with insights to the performance of a particular missile system and if necessary, enables the development of an appropriate defense system. Wind tunnel test data on an SA-2 class missile modified by suitable modeling was provided by MSIC. For this Thesis, this data set became the bench-mark for validating the Missile Datcom (97) empirical code that was used to compute the performance of the missile. The missile geometry was modeled using the interface Missile Lab. A series of simulations for different flight operating conditions was carried out. The primary quantities compared were the axial force coefficient, CA and the skin friction coefficient, Cf. This Thesis describes the results obtained along with the geometry changes that became necessary to obtain reasonable agreement.
The Effects of Incentive Mechanism on Knowledge Management Performance in China: The Moderating Role of Knowledge Attributes

Knowledge management of a new product development project team is critical for a firm's competitive advantage, and incentive mechanism is one of the most effective knowledge management drives. In this paper, we examined the effects of non-financial incentive and team-based financial incentive on knowledge management performance in China and identified the moderating effects of knowledge attributes (codifiability and teachability). Our findings indicate that non-financial incentive and team-based financial incentive have positive effects on knowledge management performance. Codifiability and teachability enhance the team-based financial incentive–knowledge management performance relationship. Finally, implications for research and practice are discussed.
