Working postures of tea pluckers and its interrelationship with their plucking efficiency

The purpose of this study was to examine posture-comfort-performance interrelationships in plucking-based task in a tea garden. Results of coefficient of correlation between the stature bush height ratio (SBHr) and total yield (TY) (permanent: r =0 .80, temporary: r =0 .81), and SBHr and body part discomfort frequency and severity (BPDFS) (permanent: r = �0.78, temporary: r = �0.77) clearly indicated that performance (TY) was correlated both with the SBHr and BPDFS. Similar correlation studies between duration (TT) and BPDFS revealed that BPDFS increased with progression of time. Analysis of joint angle changes (trunk angle 92%, shoulder angle 63% and neck angle 87%) further suggests that both BPDFS and overall postural shifts (in terms of changes in joint angles) increased with the progression of time (time on task - TT). Body part discomfort (BPD) rank order of different body parts of pluckers (upper body part discomfort scores - permanent: 2.00-6.00, temporary: 1.88-5.88; lower body part discomfort scores - permanent: 2.13-2.88, temporary: 1.88-2.75) further revealed that upper body parts were mostly involved in discomfort development. These results suggest that an overall postural shift may be a good indicator of perceived musculoskeletal discomfort in a tea leaf plucking task where a constrained posture is required. Results of independent test series suggest that there was a good agreement between the predicted and observed values of the different variables (89.6-96.3%). The predictive value of the regression equations may be utilized for estimating values of different interacting variables, and thus, the importance of these regression equations in the supervision of workers engaged in tea plucking is evident. It is therefore proposed that to improve performance, these observations can conveniently be utilized while plucking sectors are allotted to pluckers in a tea garden.
A systematic review on autistic people's experiences of stigma and coping strategies

Autism can be understood as a concealable stigmatized identity. This is the first systematic review to synthesize the literature on autistic people's experiences of stigma and coping strategies. 2877 studies were screened and 27 were included in this review. The reviewed literature demonstrates that autistic individuals are acutely aware of being stereotyped, judged, and discriminated by others. Autistic people also show signs of internalizing stigma, rendering them more vulnerable to low self‐worth and poorer mental health. To manage the impact of stigma, the included studies suggest that autistic individuals may use these strategies: concealment and camouflaging, selective disclosure and self‐advocacy, as well as positive reframing and reconstructing identity. However, the evidence is limited and mixed in terms of how helpful and effective these strategies are. Future studies should include autistic populations with a wider range of intellectual abilities and explore interventions that can support autistic people in managing stigma to supplement interventions that seek to reduce stigma towards autistic people. The power of language in perpetuating and challenging stigma also has important implications for research and practice, underscoring the need for researchers and practitioners to reflect carefully on the messages they are communicating about autism.
Early Paleocene Paleoceanography and Export Productivity in the Chicxulub Crater

The Chicxulub impact caused a crash in productivity in the world's oceans which contributed to the extinction of ∼75% of marine species. In the immediate aftermath of the extinction, export productivity was locally highly variable, with some sites, including the Chicxulub crater, recording elevated export production. The long‐term transition back to more stable export productivity regimes has been poorly documented. Here, we present elemental abundances, foraminifer and calcareous nannoplankton assemblage counts, total organic carbon, and bulk carbonate carbon isotope data from the Chicxulub crater to reconstruct changes in export productivity during the first 3 Myr of the Paleocene. We show that export production was elevated for the first 320 kyr of the Paleocene, declined from 320 kyr to 1.2 Myr, and then remained low thereafter. A key interval in this long decline occurred 900 kyr to 1.2 Myr post impact, as calcareous nannoplankton assemblages began to diversify. This interval is associated with fluctuations in water column stratification and terrigenous flux, but these variables are uncorrelated to export productivity. Instead, we postulate that the turnover in the phytoplankton community from a post‐extinction assemblage dominated by picoplankton (which promoted nutrient recycling in the euphotic zone) to a Paleocene pelagic community dominated by relatively larger primary producers like calcareous nannoplankton (which more efficiently removed nutrients from surface waters, leading to oligotrophy) is responsible for the decline in export production in the southern Gulf of Mexico.
Deep Learning based Model for Prohibited Goods Detection

With the rapid development of Internet technology, massive images are used on e- commerce sites to show product details. Among those images there are some of contraband, which seriously harm the social harmony, thus it is important to automatically identify them. In this paper, we propose an effective method aims at solving this problem, in contrast with traditional methods, we do not use human designed visual features and classification models, but combine deep features and deep learning model. Experiment results show that our method outperform previous human designed features and visual models tremendously.
A Review of the Core Concept of the Cambridge Handbook of Situated Cognition

Since its inception some fifty years ago, cognitive science has undergone a number of sea changes. Perhaps the best known is the development of connectionist models of cognition as alternatives to classical, symbol-based approaches. A more recent and increasingly influential trend is that of dynamical-systems-based, ecologically oriented models of the mind. Researchers suggest that a full understanding of the mind will require systematic study of the dynamics of interaction among mind, body, and world.
High Performance in the Temping Industry

The temporary staffing industry functions as an economic thermometer: when the industry is suffering decreasing turnover this is a clear sign the economy is cooling down and vice versa. As a consequence the industry experiences erratic financial results and has traditionally suffered from a huge employee turnover. Managers of temping agencies are therefore looking for ways to stabilise and increase their performance. One of the concepts they are investigating is that of high performance organisations (HPOs). The study described in this article takes the recently developed HPO Framework and applies this to the temporary staffing industry in order to identify factors that create and sustain high performing temping agencies. The study results show there are ten factors that are decisive for achieving long-term high performance in this industry. The practical implication is that managers should focus on improving these characteristics and thus create more stable high performing organisations.
Aligning Learning and Assessment Through Adaptive Strategies in Tutorials in Physics at the University of Auckland

Continuous assessment in physics is important for students. It provides the development of mental models by revising and revisiting concepts. In Physics 120 “Physics of Energy” and Physics 150 “Physics of Technology” at the University of Auckland, we identified that during 2007 and 2008 there was a significant and increasing non-participation rate in assignments and tests. In 2009 strategies were implemented to improve participation by adapting tutorials to be more interactive and aligned to the online assignment assessments. There were four online OASIS assignment assessments spread through each course. One week prior to submitting the assignment assessment, six practice questions were given. These questions were similar to those questions in the interactive tutorials. Four OASIS questions were given with changed variables as the assignment assessment. After the third and fourth OASIS assignments there was a strong indication that alignment between tutorial questions and assignments encouraged more participation and completion of OASIS assignments.
Student-lead evaluation of a new workplace concept in an academic environment

This paper presents the outcome of an evaluation of a new workplace concept in the staff room of the Academy of Hotel and Facility Management at the NHTV – a medium-sized school for higher vocational education – in the city of Breda, the Netherlands. The workplace concept, known as “NHTV@Work”, was centrally developed by the Facilities Division of the said school, with assistance from professional workplace consultants. The objectives of the study was (i) to determine the level of user-satisfaction or dissatisfaction with the new workplace environment, (ii) assess the implementation process by way of self-reporting by staff members using the new workplace environment, and (iii) develop recommendations for improving the overall concept for implementation across all workplace environments of the NHTV. The evaluation of the new workplace concept was considered a suitable project assignment for 2 2nd-year FM student groups of the theme “Corporate Real Estate Management”. As part of the theoretical component of this theme, students were given instruction on diverse methodologies and approaches to workplace performance evaluation through questionnaires, observations and interviews. Through the application of a process-model for supporting decision-making on organisational accommodation as conceptual framework, the various methodologies were structured to provide students an optimal learning experience.Outcomes of the research identified (i) staff members using the workplace concept to be overall satisfied with the new concept, but less satisfied with the implementation and continued monitoring thereof, (ii) the use of the workplaces to be overall well-adopted, but a need for increased diversity in the functionality of specific types of workplaces provided, and (iii) a perceived misalignment of interest between the development and the new workplace concept by the Facilities Division and external consultants on the one hand, and the perceived work culture and functional requirements of staff members. The study provides a comprehensive framework for firstly, assessing all workplace environments where the NHTV@Work concept has been implemented, and secondly, for inter-organisational comparative research and continues monitoring of the effectiveness of the workplace concept. In addition to this, the approach as applied in the current research, provides a qualitative project-based learning experience for FM-students of the Academy.
Discriminative Triad Matching and Reconstruction for Weakly Referring Expression Grounding

In this paper, we are tackling the weakly-supervised referring expression grounding task, for the localization of a referent object in an image according to a query sentence, where the mapping between image regions and queries are not available during the training stage. In traditional methods, an object region that best matches the referring expression is picked out, and then the query sentence is reconstructed from the selected region, where the reconstruction difference serves as the loss for back-propagation. The existing methods, however, conduct both the matching and the reconstruction approximately as they ignore the fact that the matching correctness is unknown. To overcome this limitation, a discriminative triad is designed here as the basis to the solution, through which a query can be converted into one or multiple discriminative triads in a very scalable way. Based on the discriminative triad, we further propose the triad-level matching and reconstruction modules which are lightweight yet effective for the weakly-supervised training, making it three times lighter and faster than the previous state-of-the-art methods. One important merit of our work is its superior performance despite the simple and neat design. Specifically, the proposed method achieves a new state-of-the-art accuracy when evaluated on RefCOCO (39.21 percent), RefCOCO+ (39.18 percent) and RefCOCOg (43.24 percent) datasets, that is 4.17, 4.08 and 7.8 percent higher than the previous one, respectively.

Multimedia Video Streaming using Advanced Compression and Bandwidth Efficient Technique

Multimedia is a modern way of communication where lots of images and videos are been transmitted over the wireless sensor network, hence managing the transmission of these records plays an important role when it comes to speed in which the multimedia transferred. In this paper compression technique and bandwidth utilization method is used for the efficient data transmission. Using this one can minimize the bandwidth utilization by compressing the video to the best format where packet won’t be lost and complete packet will be transferred to the destination node. Remote sensor systems is a developing class of exceptionally powerful, complex system condition over which a wide scope of uses, for example, living space observing, object following, exactness farming, building checking and military frameworks are assembled. [1]The ongoing applications frequently produce earnest information and one-time occasion notices that should be conveyed dependably. The fruitful conveyance of such data directly affects the general execution of the framework. Solid correspondence is significant for sensor systems. In WSN’s for viable transmission of still pictures, sound, and video data implements thorough necessities on the vitality utilization and throughput. [2] It is given in this to examine the presentation of steering traffic for interactive media traffic in WSN for multi jump nodes from the sink.
Power System Modelling and Fault Analysis of NamPower＇s 330 kV HVAC Transmission Line

Electric power systems usually cover large geographical areas and transmission facilities are continuously increasing. These power systems are exposed to different environmental conditions which may cause faults to occur on the system. Different types of studies are usually done on electric power systems to determine how the system behaves before, during and after a fault condition. The behaviour of variables of interest such as currents, voltage, rotor angle and active and reactive power under fault conditions are studied and observed to help determine possible causes of faults in a power system. The objective of this paper is to investigate a fault that occurred on the 330 kV transmission line between Ruacana power station and Omburu sub-station, the fault caused all the generators at Ruacana power station to trip and consequently caused a blackout at the power station that lasted for 6 h. Preliminary findings showed that the observed fault was an earth fault but the exact type of earth fault was however not known at the time. This research investigation sets out to determine the exact fault that occurred; the most probable cause of the fault, and propose possible solutions to prevent reoccurrence of such a fault. The section of the power network in which the fault occurred was modelled using DigSilent Power Factory software tool, and transient fault analysis was carried out on the model for different fault conditions. Results obtained were then compared with data obtained from NamPower records to ascertain the type of fault.
Engineering Software Qualities in Telecommunications : Three Cases from Industry

Software has become an integral part of telecommunication systems over the last 30 years. The relative cost for software in the systems has increased continuously over these years. This increase has meant that there has been a need to also focus on evaluation and prediction of different software qualities of the systems. This paper presents three studies evaluating software qualities in different ways. The firsts study focuses on performance and touches upon reliability. The reliability aspect is discussed in more detail in the second case study. Finally, the third study presents methods to estimate the fault content from software inspections. These studies are presented as representative examples of the work that resulted in that the author of this paper received the Telenor Nordic Research Award in 2004. Some ongoing research on engineering software qualities is also briefly presented.
Low power technology mapping and performance driven placement for field programmable gate arrays

As technology geometries have shrunk to the deep sub-micron (DSM) region, the chip density and clock frequency of FPGAs have increased significantly. This makes computer-aided design (CAD) for FPGAs very important and challenging. Due to the increasing demands of portable devices and mobile computing, low power design is crucial in CAD nowadays. In this dissertation, we present a framework to optimize power consumption for technology mapping onto FPGAs. We propose a low-power technology mapping scheme which is able to predict the impact of choosing a subnetwork covering on the ultimate mapping solution. We dynamically update the power estimation for a sequence of options and choose the one that yields the least power consumption. This technique outperforms the best low-power mapping algorithms reported in the literature. We further extend this work to generate mapping solutions with optimal delay. We also propose placement algorithms to optimize the performance of the placed circuit. Net cluster based methodology is designed to ensure closely connected nets will be routed in the same region. Net cluster is obtained by clique partitioning on the net dependency graph. Net positions and consequent cell positions are computed with a force-directed approach which drags nets connected to closer positions. We further study the performance-driven placement problem for high level synthesis. We use the Automatic Design Instantiation (AUDI) high level synthesis system to generate an register-transistor level (RTL) netlist. This RTL netlist is fed into an CAD tool for physical synthesis. We do not necessarily go through the entire physical design process which is usually quite time-consuming. Instead, we have created an accurate wirelength/timing estimator working on the floorplan. If the estimated timing information does not meet the constraints, a guidance is generated and provided to AUDI system. The guidance consists of the estimated timing information and instructions to produce a new netlist in order to improve the performance. Finally the circuit is placed and routed on a satisfying design. This performance-driven placement framework yields better results as compared to a commercial CAD tool.
Performance of STBC-OFDM Systems over Spatial Correlated Fading Channels

A MIMO-OFDM system using space-time bloek coding can combat frequency selectivity fading and achieve diversity gains. The closed form solution to Symbol Error Rate (SER) of the system is derived over Rayleigh correlated fading environment, which . shows that the performance of the system is mainly determined by the eigenvalues and their multiplicities of the MIMO correlation matrix. Simulation results for 2 transmit and 2 receive imply that the impact of transmit correlated only or receive correlated only on the performance is lower than that of both transmit and receive correlated at the same correlation coefficient, whereas both transmit and receive correlated is a little better than transmit correlated only or receive correlated only when the correlation of the former is lower than that of the latter to some extent.
MACROSCOPIC PROPERTIES OF AN ORTHOTROPIC ELASTIC MEDIUM CONTAINING ARBITRARILY ORIENTED CRACKS: APPLICATION TO DAMAGE

An analytical method for the determination of the E shelby tensor S associated with an ar- bitrarily oriented crack in an orthotropic elastic medium is first presented. The crack is modelled as an infinite cylinder (with low aspect ratio) along one symmetry axis of the solid matrix. The proposed methodology yields explicit expressions of the Eshe lby tensor (or equivalently the Hill tensor P) which show the interaction between the structural a nisotropy and the cracks-induced anisotropy. These results are then introduced into a Mori-Tanak a homogenization scheme in order to determine the macroscopic quantities (stiffness tensor, energ y) of the cracked media. A last part of the study i s devoted to the formulation of an anisotropic damage model based on the micromechanical results. The ability of this model to describe the inelastic behaviour of brittle matrix composites is demon- strated. Moreover, quantitative comparisons with ex perimental data on a Ceramic Matrix Composite (unidirectional SiC-SiC) are provided.

A COMPUTER SIMULATION FOR LEG STIFFNESS IN MAXIMAL SPRINTING

When humans and other mammals run, the body's complex system of muscle, tendon and ligament behave like spring. A computer simulation for terrestrial running at maximal speed is presented in this study, based on a leg with the properties of non-linear spring. At maximal speed, the horizontal speed has 'been conSidered constant while the vertical component was considered zero at landing. Three non-linear springs have been considered for quadriceps, hamstring, and gastrocnemius muscles with different stiffness coefficients. The goal of present study was to determine the relative importance of changes to the leg spring stiffness and the angle swept by the leg spring when the sprinter alters the landing angles (from braking to take-off) at maximal speed. Results also showed that at maximal speed the stiffness coeffiCients presented non-linear behaviour.
