A New Approach to Crop-Row Detection in Corn

This paper describes a new machine vision based method for detecting field crop-rows in corn. The method can be applied to guidance system in agricultural robots or autonomous vehicles. Instead of using the classical Hough transform, a method based on curve fitting and iteration was developed. This method was proved to be more robust with respect to noise caused by the large leaves and can provide better accuracy. In addition, it features reduced computational complexity of the image-processing algorithm. The algorithm operates on binary images, which were segmented from RGB images based on color information. The segmentation was adapted to various lighting conditions. The interference caused by weeds and crop residuals was decreased by using a spatial filter. It is also robust with respect to special conditions, for example, the occurrence of the end of the rows or weed presence. A fifth order low pass filter was used to increase the efficiency and accuracy of the detecting algorithm. The algorithm was tested on 100 images, among which 98 percent received acceptable results. A traditional Hough Transform based row detection method was chosen as a reference, the method of this paper was proven to have a better result in both accuracy and time costs. The processing time was 0.13 second per image on average.
Contribution to the special issue on clinical ethology: On the applicability of eye movement desensitization and reprocessing (EMDR) as an intervention in dogs with fear and anxiety disorders after a traumatic event

Fear and anxiety disorders are prevalent in dogs. These disorders are not adequately resolved by current interventions, which urges exploration of additional interventions. In humans, fear and anxiety disorders such as post-traumatic stress disorder (PTSD), are effectively treated by Eye Movement Desensitization and Reprocessing (EMDR). EMDR is a non-invasive and non-pharmacological intervention involving bilateral sensory stimulation while memorizing the traumatic event, resulting in decreased emotionality of the memory. We argue EMDR might be applied as an intervention for fear and anxiety disorders in dogs, adding to the currently available interventions for the field of Clinical Ethology. Particularly nonverbal EMDR protocols used in preverbal children can be applied and the setup can be adapted for dogs. Future research should focus on the development of nonverbal EMDR protocols including proper controls, and on clinical effectiveness of such EMDR protocols for dogs. Apart from behavioural measures, psychophysiological variables should be incorporated as well.
The metric tide: report of the independent review of the role of metrics in research assessment and management

This report presents the findings and recommendations of the Independent Review of the Role of Metrics in Research Assessment and Management. The review was chaired by Professor James Wilsdon, supported by an independent and multidisciplinary group of experts in scientometrics, research funding, research policy, publishing, university management and administration. This review has gone beyond earlier studies to take a deeper look at potential uses and limitations of research metrics and indicators. It has explored the use of metrics across different disciplines, and assessed their potential contribution to the development of research excellence and impact. It has analysed their role in processes of research assessment, including the next cycle of the Research Excellence Framework (REF). It has considered the changing ways in which universities are using quantitative indicators in their management systems, and the growing power of league tables and rankings. And it has considered the negative or unintended effects of metrics on various aspects of research culture. The report starts by tracing the history of metrics in research management and assessment, in the UK and internationally. It looks at the applicability of metrics within different research cultures, compares the peer review system with metric-based alternatives, and considers what balance might be struck between the two. It charts the development of research management systems within institutions, and examines the effects of the growing use of quantitative indicators on different aspects of research culture, including performance management, equality, diversity, interdisciplinarity, and the ‘gaming’ of assessment systems. The review looks at how different funders are using quantitative indicators, and considers their potential role in research and innovation policy. Finally, it examines the role that metrics played in REF2014, and outlines scenarios for their contribution to future exercises.
A Workshop on Analysis and Evaluation of Enterprise Architectures

Abstract : This report summarizes a workshop on analysis and evaluation of enterprise architectures that was held at the Carnegie Mellon Software Engineering Institute (SEI) in April of 2010. The SEI invited accomplished practitioners from government and industry to discuss key issues in analyzing and evaluating enterprise architectures. After several opening talks by individuals who presented the state of the practice of enterprise architecture within their own organizations, the group considered a series of questions, including (1) Is there a fundamental difference between analyzing and evaluating enterprise architectures and system of system architectures? (2) How are quality attribute concerns expressed and analyzed in practice for an enterprise architecture? (3) How are enterprise architectures evaluated in practice? For each question, discussion included consideration of the current state of the practice, identification of difficulties sufficient to motivate an organization to seek a solution or an alternative (? pain points? ), challenges in current practice, and differences between government and industry contexts. This report summarizes the workshop dialogue and findings, and presents a proposal for an Enterprise Architecture Analysis and Evaluation process.
60 GHz dual‐polarized magneto‐electric dipole antenna array with hybrid gap waveguide feeding network in low temperature co‐fired ceramic technology

A 60 GHz 8 × 8 dual‐polarized aperture‐coupled magneto‐electric (ME) dipole antenna array in low temperature co‐fired ceramic (LTCC) technology is proposed. Taking advantage of the LTCC technology of high integration, the antenna array is composed of three parts, including the wideband ME dipole elements, dual‐polarized strip‐line series feeding network and low‐loss gap waveguide (GWG) feeding network. The ME dipole antenna element is fed by aperture coupling with 45° rotation. Two separate orthogonal strip lines are located right below the aperture to realize dual polarization performance. The simulated −10 dB impedance bandwidth of the dual‐polarized antenna element is 50–66.5 GHz with an isolation lower than −20 dB for two input ports. By employing the proposed radiating element, a 4 × 4 wide‐band dual‐polarized antenna subarray is realized by using strip‐line series‐feed technology. A compact hybrid low‐loss feeding network is realized by combing the GWG technology with the strip‐line series feed technology. For demonstration, one prototype was fabricated. The measured impedance bandwidth is 14.2% and 16.7% respectively for dual polarizations with |S11| < −8 dB, and the port isolation is lower than −20 dB over the entire frequency band of interest.
A first record of a land-bird being trapped by 'Pisonia umbellifera'

The sticky fruits of the tree species Pisonia umbellifera and P. grandis (Nyctaginaceae) have been recognised as significant sources of mortality on some off-shore seabird colonies. Both adults and nestlings of seabirds such as Gould's Petrel Pterodroma leucoptera leucoptera (Priddel and Carlile, 1995, 1998) and Black Noddy Anous minutus (Ogden, 1993) can become ensnared in the numerous sticky fruits and die. Indeed, the mortality of Gould's Petrels due to P. umbellifera is a key threatening process for this vulnerable species (Garnett and Crowley, 2000; Priddel and Carlile, 1995), and even single fruits have been recorded as causing mortality (Priddel and Carlile, 1995).
SCHEDULING PROBLEMS FOR JOBS AND DIFFERENT MACHINES WITH MAKE SPAN CRITERION AND LEFT TIME ALIGNMENT

This paper focuses on operations scheduling, which involves assigning jobs to workstations or employees to jobs for specified time period. The scheduling techniques we discuss in this paper are similar with Gantt method type and serv various process types in manufacturing process. There are companies which have to deliver many types of different products in a specified time, as, for example, a slewing ring factory, which has to sell a large variety of products (taking into account dimensions and configurations), in the same time.
Direct load angle control of three phase induction motor drives

In this paper, a direct load angle (DLA) control method for three phase induction motor drives is proposed. It is based on control of incremental change in load angle. This method offers constant switching frequency at different operating conditions. The torque control is achieved without losing the benefits of direct torque control (DTC) by reference stator flux angle, which is sum of load angle and rotor flux angle. Proposed DLA control method is applied to two level and three level voltage source inverter fed induction motors and results are presented. From the simulation results it is found that the proposed DLA control scheme impressively reduced the torque and flux ripples when compared with conventional DTC.
A Study of Laser Aided Activating TIG Welding

Laser aided activating TIG welding was called LA-TIG. At first, the surface of weld was melted by the mini power laser protected by oxygen, and then the conventional TIG was used to cover the weld, which achieved the target of the weld with deeper penetration and narrower width. In this article, the weld bead morphology, arc images, microstructures and mechanical properties of laser aided activating TIG welding joint were analyzed. The results shows that the penetration increased significantly, excellent weld appearance and finger shape penetration were gained by laser aided activating TIG welding. It was found that the arc images of the LA-TIG was only the enlarged form compared with which observed in the conventional TIG and the arc constriction was also observed. LA-TIG weld exhibits better mechanical properties than the conventional TIG welding. Thus laser aided activating TIG welding was developed as a novel active welding method.
Academic Library in Nigeria: Yesterday, Today and Tomorrow

What is today seen as academic library in Nigeria is the effort of several metamorphorical advancements that begin many years ago outside of the country. Yesterday it was merely a house that houses books for the purpose of protecting them. While today it is a physical building that provides knowledge and information to researchers and students of it home institution, tomorrow it is expected to be an intellectual vitality for mankind across institutional and national boundaries. By implication, the academic library is changing with technological advancements. This paper therefore makes every effort to provide an overview of the history of academic library as well as highlight some recommendations to strengthen academic library relevance in the twenty-first century advancement of information technology.

A method for synthesising linear aperture distribution patterns with different side lobe levels (SLLs) on both sides of the main beam is proposed. This phase-only control method was applied to a Taylor distribution as well as to a uniform amplitude distribution and achieved differences in the SLL on both sides of the main beam as great as 23 dB, improving on a previous procedure that had achieved a gap of little more than 10 dB.
Overlay budget considerations for an all-scanner fab

According to the SIA roadmap an overlay of 65nm is necessary for state of the art 0.18micrometers processes. To meet such tight requirements it is necessary to know the magnitude of all contributions, to understand possible interactions and to try to drive every individual overlay component to its ultimate lower limit. In this experimental study we evaluate the impact of different contributions on the overall overlay performance in a fab equipped exclusively with ASML step and scan systems. First we discuss the overlay performance of advanced step and scan systems in a mix and match scenario, focusing on single machine overlay, long term stability and multiple machine matching. We show that both distortion and stage differences between different tools are typically less than 22nm, justifying a multiple machine scenario without significant loss of overlay performance. In the next step, we discuss the impact of layer deposition and CMP. We include shallow trench isolation, tungsten-CMP as well as conventional aluminum wiring and copper-dual-damascene technology into our examinations. In particular, we discuss the pro's and con's of using a zero-layer-mark-approach, compared to an alignment on marks formed in certain layers for direct layer to layer alignment. Furthermore, we examine the performance of ASMLs 'through-the-lens' (TTL)-alignment system becomes as small as 6nm using TTL-alignment. For marks directly affected by CMP-processes technology impact can be controlled within 13nm. We show that, even in a scenario with multiple tools matched to each other, where alignment marks are directly affected by a CMP process step, and where the standard TTL alignment marks are directly affected by a CMP process step, and where the standard TTL alignment system is used, the overall overlay can be controlled within 60nm. Using the ATHENA alignment system, a further improvement is possible.
Occupation dynamics and nesting behaviours of Xylocopa frontalis (Olivier) (Hymenoptera: Apidae) in artificial shelters

ABSTRACT We described herein the colonisation dynamics of trap-nests by females of the giant carpenter bee Xylocopa frontalis (Olivier). The behaviours performed by emerging females, such as philopatry and dispersal, were quantified in different environments and conditions of nest supply. Two artificial shelters containing high and low provision of trap-nests were installed in two areas to attract nesting females. It was detected a higher number of new foundations compared to nest reuse regardless the number of trap-nests provided. Full use of the available nests in shelters was not detected. Most of the emerging females dispersed from artificial shelter and the colonisation was made by both philopatric and vicinity females. No differences in the number of offspring produced by nesting females was observed among shelters but the number of brood cells in the newly founded nests was higher than that of the reused nests. The maximum span that a female remained in the shelter was 290 days. For dispersing females, the minimum permanence time in the shelter was 12 days ( = 45 days). We conclude that the differences on availability of artificial substrates between the shelters was not sufficient to affect the number of constructed nests and the behaviours performed by nesting females. Additionally, it can be suggested that the higher number of dispersing females associated with the attraction of vicinity females can contribute to maximise the genetic variability of X. frontalis populations maintained in artificial shelters, aiming the management of this important pollinator in agro-ecosystems.
Time Series-, Time-Frequency- and Spectral Analyses of Sensor Measurements in an Offshore Wave Energy Converter Based on Linear Generator Technology

Inside the second experimental wave energy converter (WEC) launched at the Lysekil research site on the Swedish west coast in March 2009 a number of sensor systems were installed for measuring the mechanical performance of the WEC and its mechanical subsystems. One of the measurement systems was a set-up of 7 laser triangulation sensors for measuring relative displacement of the piston rod mechanical lead-through transmission in the direct drive. Two measurement periods, separated by 2.5 month, are presented in this paper. One measurement is made two weeks after launch and another 3 months after launch. Comparisons and correlations are made between different sensors measuring simultaneously. Noise levels are investigated. Filtering is discussed for further refinement of the laser triangulation sensor signals in order to separate noise from actual physical displacement and vibration. Measurements are presented from the relative displacement of the piston rod mechanical lead-through, from magnetic flux in the air gap, mechanical strain in the WEC structure, translator position and piston rod axial displacement and active AC power. Investigation into the measurements in the time domain with close-ups, in the frequency domain with Fast Fourier transform (FFT) and with time-frequency analysis with short time Fourier transform (STFT) is carried out to map the spectral content in the measurements. End stop impact is clearly visible in the time-frequency analysis. The FFT magnitude spectra are investigated for identifying the cogging bandwidth among other vibrations. Generator cogging, fluctuations in the damping force and in the Lorenz forces in the stator are distinguished and varies depending on translator speed. Vibrations from cogging seem to be present in the early measurement period while not so prominent in the late measurement period. Vibration frequencies due to wear are recognized by comparing with the noise at generator standstill and the vibration sources in the generator. It is concluded that a moving average is a sufficient filter in the time domain for further analysis of the relative displacement of the piston rod mechanical lead-through transmission.
