Modeling Larval Transport and Settlement of Pink Shrimp in South Florida: Dynamics of Behavior and Tides
Authors: Criales Maria M. , Cherubin Laurent M. , Browder Joan A. 
Published: May 2015

Abstract
The pink shrimp Farfantepenaeus duorarum, one of the commercially important Penaeidae, reproduces offshore of the southwest Florida (SWF) shelf. Larvae migrate to nursery grounds in estuarine Florida Bay. Using a numerical approach, we investigated the role of spawning location, larval traits, and physical forces on the transport of pink shrimp larvae. First, the Regional Oceanic Modeling System that is based on tides, air–ocean fluxes, and freshwater flows was used to simulate the SWF shelf oceanography. The model replicates the tides, winds, salinity, currents, and seasonality of the shelf. Secondly, the Regional Oceanic Modeling System was coupled offline with the Connectivity Modeling System, in which virtual larvae were released near the surface from two spawning sites, Dry Tortugas and Marquesas, and tracked until the time for settlement (about 28–30 d). Virtual larvae moved vertically in the water column following ontogenetic behaviors previously observed in the field: diel vertical migration (DVM) and selective tidal stream transport (STST). Lagrangian trajectories indicated that migration paths changed radically between summer and winter during model years (1995–1997). Maximum settlements occurred in summer by larvae crossing the SWF shelf, while the lowest settlement occurred in winter by larvae moving through passes in the Florida Keys. Modeling results demonstrated an effective east-northeast transport across the SWF shelf during summer as a result of the tidal currents, the subtidal currents, and the combined DVM and STST behaviors. The current phase captured during the initial DVM period was critical to determine the direction in which larvae move, favorable (east and northward) or unfavorable (south and westward), before the STST behavior captures the eastward tidal current that brings larvae to the nursery grounds. Unfavorable currents were driven by the summer easterlies and low salinities at the coast. Results indicated that Marquesas is the more effective spawning ground, with 4.5 times more likely settlement of originating larvae compared with Dry Tortugas. Model-estimated seasonal settlement patterns concurred with postlarval influxes previously observed at Florida Bay boundaries.

It also appears from the analysis that the effect of internal control and its components on ROA and ROE is significant and positive, while the effect on EPS and PM is positive but statistically insignificant.Practical implications– Corporate managements should review the effectiveness of the implementation of internal control requirements, especially those related to control environment, information and communication and monitoring.Social implications– The findings of the study shed light on the relevance of internal control systems of the Saudi shareholding companies in improving the financial performance of the these companies, which is expected to help in safeguarding the interests of all interest groups and improve the society’s well-being.Originality/value– The paper provides new evidence about the relationship between internal control and profitability in the Saudi Arabian environment. The findings of the study add good contribution to the literature because they direct our attention to the expected effect of the environment on the relationship between internal control and performance. The results may suggest that there is a need to expand this study using other methodologies to delve into the depths and understand this phenomenon within its context.
HSE management standards indicator tool and positive work-related outcomes
Authors: Toderi Stefano , Balducci Cristian 
Published: May 2015

Purpose
– The purpose of this paper is to evaluate if the Management Standards (MS) Indicator Tool developed by the Health and Safety Executive (HSE) for the assessment of work-related stress is associated with positive work-related outcomes.

Design/methodology/approach
– In total, 326 employees of an Italian firm filled in a questionnaire including the HSE Indicator Tool (measuring MS) and validated scales investigating personal development, job performance and Organizational Citizenship Behaviour (OCB). Regression analyses were run to evaluate the explained variance of the outcomes and the demands/control interaction effect hypothesized by Karasek’s active learning hypothesis.

Findings
– The MS explained variance of all the outcomes analysed and the active learning hypothesis was confirmed for personal development. Contrary to previous studies on negative stress-related outcomes, “job content” MS were the most important predictors. However, higher job demands were unexpectedly positively associated with the outcomes.

Practical implications
– Taking into account positive work-related outcomes could provide organizations with additional information for the development of interventions with greater emphasis on preventive orientation (improvement of health, well-being and motivation, rather than only work stress reduction).

Originality/value
– The study provides new insight into the relationship between MS and positive work-related outcomes, thus expanding the nomological network of the Indicator Tool questionnaire and giving empirical evidence to the notion of the “business case” for work stress prevention. Firms performing well on MS could expect greater worker development and higher performance.

A modified welding image feature extraction algorithm for rotating arc narrow gap MAG welding
Authors: Li Wenhang , Ji Yunhong , Wu Jing , Wang Jiayou 
Published: May 2015

Purpose
The purpose of this paper is to provide a modified welding image feature extraction algorithm for rotating arc narrow gap metal active-gas welding (MAG) welding, which is significant for improving the accuracy and reliability of the welding process.

Design/methodology/approach
An infrared charge-coupled device (CCD) camera was utilized to obtain the welding image by passive vision. The left/right arc position was used as a triggering signal to capture the image when the arc is approaching left/right sidewall. Comparing with the conventional method, the authors’ sidewall detection method reduces the interference from arc; the median filter removes the welding spatter; and the size of the arc area was verified to reduce the reflection from welding pool. In addition, the frame loss was also considered in the authors’ method.

Findings
The modified welding image feature extraction method improves the accuracy and reliability of sidewall edge and arc position detection.

Practical implications
The algorithm can be applied to welding seam tracking and penetration control in rotating or swing arc narrow gap welding.

Originality/value
The modified welding image feature extraction method is robust to typical interference and, thus, can improve the accuracy and reliability of the detection of sidewall edge and arc position.
Power pylon detection and monocular depth estimation from inspection UAVs
Authors: Araar Oualid , Aouf Nabil , Vallejo Dietz Jose Luis 
Published: May 2015

Purpose
This paper aims to present a new vision-based approach for both the identification and the estimation of the relative distance between the unmanned aerial vehicle (UAV) and power pylon. Autonomous power line inspection using small UAVs, has been the focus of many research works over the past couple of decades. Automatic detection of power pylons is a primary requirement to achieve such autonomous systems. It is still a challenging task due to the complex geometry and cluttered background of these structures.

Design/methodology/approach
The identification solution proposed, avoids the complexity of classic object recognition techniques. Instead of searching the whole image for the pylon template, low-level geometric priors with robust colour attributes are combined to remove the pylon background. The depth estimation, on the other hand, is based on a new concept which exploits the ego-motion of the inspection UAV to estimate its distance from the pylon using just a monocular camera.

Findings
An algorithm is tested on a quadrotor UAV, using different kinds of metallic power pylons. Both simulation and real-world experiments, conducted in different backgrounds and illumination conditions, show very promising results.

Research limitations/implications
In the real tests carried out, the Inertial Navigation System (INS) of the vehicle was used to estimate its ego-motion. A more reliable solution should be considered for longer distances, by either fusing INS and global positioning system data or using visual navigation techniques such as visual odometry.

Originality/value
A simple yet efficient solution is proposed that allows the UAV to reliably identify the pylon, with still a low processing cost. Considering a monocular solution is a major advantage, given the limited payload and processing power of such small vehicles.
Energy efficient actuators with adjustable stiffness: a review on AwAS, AwAS-II and CompACT VSA changing stiffness based on lever mechanism
Authors: Jafari Amir , Tsagarakis Nikos , Caldwell Darwin 
Published: May 2015

Purpose
This paper aims to discuss, analyze and compare members of a group of actuators with adjustable stiffness, namely: AwAS, AwAS-II and CompACT variable stiffness actuator (VSA) developed at Italian Institute of Technology (IIT).

Design/methodology/approach
These actuators are among series type of VSAs where one main motor is dedicated for link positioning and a secondary motor, in series with the first one, regulates the output link stiffness. Regulating the stiffness in this group of actuators is based on the lever concept. Initially, springs were moved along the lever to tune the stiffness while in the later versions stiffness was regulated through relocating pivot point along the lever.

Findings
This paper discusses how different mechanisms have been employed in realization of the lever concept in these actuators and what are the advantages and disadvantages of each realization.

Practical implications
Today’s robots are not supposed to be solid, isolated and rigid anymore but rather adaptive, cooperative and compliant entities in our daily life. The new attitudes demand for novel technologies substantially different from those developed for industrial domains both at the hardware and the software levels. This work presents latest three state-of-the-art actuators, developed at IIT, which are great answers to the needs of tomorrow’s robot.

Originality/value
These novel actuators are really ready for commercial exploitation, as they are compact and reliable. The main novelty is based on employing concept of lever mechanism for stiffness regulation. They have been designed and manufactured in a very professional and optimized way.
Reusing industrial robots to achieve sustainability in small and medium-sized enterprises (SMEs)
Authors: Bi Z.M. , Liu Yanfei , Baumgartner Blane , Culver Eric , Sorokin J.N. , Peters Amanda , Cox Blaine , Hunnicutt Jessica , Yurek John , O’Shaughnessey Stephen 
Published: May 2015

Purpose
The purpose of this paper is to illustrate the importance of redesigning, reusing, remanufacturing, recovering, recycling and reducing (6R) to sustainable manufacturing and discuss the general procedure to reconfigure robots. Two critical challenges in adopting industrial robots in small and medium-sized enterprise (SMEs) are flexibility and cost, as the number of tasks of the same type can be limited because of the size of an SME. The challenges can be alleviated by 6R. The 6R processes allow a robot to adopt new tasks, increase its utilization rate and reduce unit costs of products.

Design/methodology/approach
There is no shortcut to implement sustainable manufacturing. All of the manufacturing resources in a system should be planned optimally to reduce waste and maximize the utilization rates of resources. In this paper, modularization and reconfiguration are emphasized to implement 6R processes in sustainable manufacturing; robots are especially taken into consideration as core functional modules in the system. Modular architecture makes it feasible to integrate robots with low-cost customized modules for various tasks for the high utilization rates. A case study is provided to show the feasibility.

Findings
Finding the ways to reuse manufacturing resources could bring significant competitiveness to an SME, in the sense that sophisticated machines and tools, such as robots, can be highly utilized even in a manufacturing environment with low or medium product volumes. The concepts of modularization and 6R processes can be synergized to achieve this goal.

Research limitations/implications
The authors propose the strategy to enhance the utilization rates of core manufacturing resources using modular architecture and 6R practice. The axiomatic design theory can be applied as the theoretical fundamental to guide the 6R processes; however, a universal solution in the implementation is not available. The solutions have to be tailored to specific SMEs, and the solutions should vary with respect to time.

Practical implications
To operate a sustainable manufacturing system, a continuous design effort is required to reconfigure existing resources and enhance their capabilities to fulfill new tasks in the dynamic environment.

Social implications
The authors focus on the importance of sustainable manufacturing to modern society, and they achieve this goal by reusing robots as system components in different applications.

Originality/value
Sustainable manufacturing has attracted a great deal of attention, although the operable guidance for system implementation is scarce. The presented work has thrown some light in this research area. The 6R concept has been introduced in a modular system to maximize the utilizations of critical manufacturing resources. It is particularly advantageous for SMEs to adopt sophisticated robots cost-effectively.
