Quantitative assessment of beef quality with hyperspectral imaging using machine learning techniques

Nowadays, meat quality assessment attracts increasing attention in hyperspectral imaging as it provides non-intrusive measurement of various attributes of fresh meat such as beef and pork in terms of surface colour, tenderness and pH et al. Typical works can be found in Gowen et al (2007), Maltin et al (2003), Qiao et al (2007) and Eimasry et al (2012), where near-infrared (NIR) hyperspectral imaging systems are usually used. In Qiao et al (2007), selected bands are employed for prediction of drip loss, pH and surface colour of pork, using models determined by neural networks. The prediction correlation coefficients for the three parameters are 0.77, 0.55 and 0.86, respectively. In Eimasry et al (2012), principal component analysis (PCA) is utilised for data reduction, followed by partial least square regression for the prediction of surface colour (L*b*), pH and tenderness, and the prediction correlation values achieved are 0.88, 0.81, 0.73 and 0.83. However, using data captured under commercial conditions in Craigie et al (2010), the prediction correlation values for L*, b*, pH and tenderness are only about 0.2, 0.35, 0.2 and 0.1, respectively. On one hand, this has indicated that the predicted results are critically affected by the conditions when the spectral data are captured. On the other hand, such data is preferred as it reflects commercial conditions for practical applications. Using the challenging data in Craigie et al (2010), support vector machine is applied for prediction of L*, b*, pH and tenderness, followed by dimension reduction using PCA on the entire dataset. With optimised kernels and parameters, we have successfully improved the prediction correlation values to about 0.55, a significant improvement in comparison to the original results.
Economic Analysis of Wood- or Bark-Fired Systems.

Abstract : The Tennessee Valley Authority, in cooperation with the U.S. Department of Agriculture and the Forest Products Research Society, is preparing three slide-tape presentations to help people evaluate wood- and bark-fueled boiler systems as alternatives to ones using oil, gas, or coal. The first two presentations cover equipment selection and estimation of fuel values; the third describes procedures for evaluating financial aspects. This report is the basis for the third slide-tape presentation. It can be used as a complement to the audiovisual program, or by itself as a guide to analysis of boiler system investments. (Author)
An Efficient Centralized Planner for Multiple Automated Guided Vehicles at the Crossroad of Polynomial Curves

In this letter, we introduce acentralized planner with low computational cost to schedule the motions of multiple Automated Guided Vehicles (AGVs) at the intersection of pre-defined polynomial curves. In particular, we find that the collision conditions between two AGVs along polynomial paths can be formulated as a set of polynomial inequalities. Furthermore, by solving these inequalities, the continuous boundaries of potential collision areas for vehicles can be determined offline and stored in a table. During the online phase, by also taking into account the priority setup among AGVs, the planner will use efficient table lookup to determine a list of intermediate goals for each AGV to move toward based on their real-time position feedback. In this way, the multiple robots are able to navigate on polynomial guide paths safely and efficiently at the crossroad, and the performance of our approach is demonstrated in a number of simulated scenarios. Videos of the experiments are available at https://sites.google. com/view/zqzhang/agvsplanner.
SAMS Acceleration Measurements on MIR

During NASA Increment 3 (September 1996 to January 1997), about 5 gigabytes of acceleration data were collected by the Space Acceleration Measurement System (SAMS) onboard the Russian Space Station, Mir. The data were recorded on 11 optical disks and were returned to Earth on STS-81. During this time, SAMS data were collected in the Priroda module to support the following experiments: the Mir Structural Dynamics Experiment (MiSDE) and Binary Colloidal Alloy Tests (BCAT). This report points out some of the salient features of the microgravity environment to which these experiments were exposed. Also documented are mission events of interest such as the docked phase of STS-81 operations, a Progress engine burn, attitude control thruster operation, and crew exercise. Also included are a description of the Mir module orientations, and the panel notations within the modules. This report presents an overview of the SAMS acceleration measurements recorded by 10 Hz and 100 Hz sensor heads. Variations in the acceleration environment caused by unique activities such as crew exercise and life-support fans are presented. The analyses included herein complement those presented in previous mission summary reports published by the Principal Investigator Microgravity Services (PIMS) group.

Targeted regulation of episomal plasmid DNA expression in eukaryotic cells with a methylated-DNA-binding activator

Purpose Targeted regulation of transfected extra-chromosomal plasmid DNA typically requires the integration of 9 - 20 bp docking sites into the plasmid. Here, we report an elegant approach, The Dpn Adaptor Linked Effector (DAL-E) system, to target fusion proteins to 6-methyladenosine in GATC, which appears frequently in popular eukaryotic expression vectors and is absent from endogenous genomic DNA. Methods: The DNA-binding region from the DpnI endonuclease binds 6-methyladenosine within the GATC motif. We used a Dpn-transcriptional activator (DPN7-TA) fusion to induce gene expression from transiently transfected pDNAs. Results We validated methylation-dependent activity of DPN7-TA with a panel of target pDNAs. We observed stronger transactivation when GATC targets were located upstream of the transcriptional start site in the target pDNA. Conclusion: DAL-E, consisting of a 108 aa, 12 kD DNA-binding adaptor and a 4 bp recognition site, offers a genetically-tractable, tunable system that can potentially be redesigned to recruit a variety of regulators (e.g. activators, silencers, epigenome editors) to transfected plasmid DNA. LAY SUMMARY Transfection of plasmid DNA (pDNA) is a commonly used method for introducing exogenous genetic material into mammalian cells. Once introduced into cells not all pDNAs express this genetic material at sufficient levels. Current techniques to improve transgene expression are limited and are not always feasible for all plasmids. This report presents a new method to improve gene expression from pDNA. The Dpn Adaptor Linked Effector (DAL-E) binds to methylated adenines in the pDNA resulting in increased expression. This technique has exciting implications for improved genetic engineering of mammalian cells. GRAPHICAL ABSTRACT
The Development and Initial Validation of the Unmanned Aerial Vehicle (UAV) External Pilot Selection System.

Abstract : The purpose of this study was to develop physical and selection performance standards for the screening of candidates for entrance into the Unmanned Aerial Vehicle UAV) Pioneer Pilot training program. A minimum Pioneer crew consists of an external pilot, internal pilot, and a mission commander/payload specialist. The mission commander/payload specialist is responsible for the overall planning and execution of the specific mission and control of the visual/information gathering during the mission. The internal pilot is responsible for the control of the Pioneer when it is beyond visual range. The external pilot is responsible for takeoffs, landings, and any in- visual-range control of the vehicle. A task analysis was done in the training and fleet squadrons to identify critical tasks for safe flight and the relevant skills required to perform the piloting tasks. From this task analysis, specific computer-based tests batteries were chosen as potential predictor variables. The system was programmed and students and external pilots were administered the test battery. A composite training measure was created from objective training scores, verified with subjective instructor ratings, and used as the criterion for predictive validation of the system. The sample size was small for the preliminary model, but a significant relationship between a composite of multitask tracking scores and UAV performance was observed (adjusted R2 = 0.86). In addition, structured and unstructured interviews of the Pioneer crews, students, instructors and senior squadron personnel were used to identity important physical characteristics essential for safe operation of the Pioneer. These traits were then used to derive medical screening criteria for all crew positions.
The Impact of Transformational Leadership Factors on Project Progress and which Factor has Significant Influence and Great Contribution towards Project Success

Projects are essential drivers for business growth and success. The project’s aim is analyzing the effect of transformational leadership factors on succeeding the projects. The study will investigate transformational leadership factors (Idealized Influence, Inspirational Motivation, Intellectual Stimulation & Individualized Consideration) and their direct influence on project success. Examining the impact of each factor will support project leaders and project resources to influence project progress for delivering and achieving project success and eliminating potential project losses and unnecessary project failures. Data from 216 project members working in Saudi Arabia for managing and executing projects were gathered and screened before being analyzed and empirically tested using the Structural Equation Model. The findings are supported for hypotheses suggested and showed that transformational leadership as well as 3 factors (idealized influence, intellectual stimulation and individual based consideration) have a significant relationship influencing progress and ultimately impacting project success. The study concludes that inspirational motivation has insignificant effect on project success. The results are inviting project leaders to adopt transformational leadership and raise the awareness, which stimulates the employees to express their ideas, effective feedback, and concerns to create a situation for the employee to deliver best performance levels. The most significant contribution is recognizing the positive effect of at the transformational leadership on study progress and ultimately help project managers to secure the success.
Why is the proposal alone not sufficient for grant success? Building research fundability through collaborative research networking

ABSTRACT With current constraints of public funding of research the question of principal investigator (PI) success has gained prominence. Yet understanding grant success remains problematic. While often associated with peer acceptance of the proposal text, research fundability in large part is informed by PI participation in the social systems of research funding, knowledge making, and academic work. This article reports on part of an in-depth longitudinal exploration of how three expert science PIs in Canada navigate and negotiate these contexts to achieve sustained grant funding success. It focuses on how one of these scientists develops and draws on collaborative research networks in creating fundable front-line knowledge. The findings contribute towards an understanding of the role experiential learning and individual agency play in PI success. Practical implications for early-career researchers are outlined. Further questions about the interconnectedness of PI navigating and negotiating research funding and knowledge and academic work are raised.
Maintaining a bus schedule

The maintaining of a regular schedule is important for the satisfactory and efficient operation of a bus service. The way in which a deviation from the regular schedule tends to amplify and give off schedule running of buses is investigated by considering a simple mathematical model of a service between a city and suburbs. It is shown that as buses pick up passengers through the city there is a tendency for buses to pair together. The behaviour of the model suggests several important factors which should be considered in the practical operation of a bus service (A).

Radial conduction effects in transient heat transfer experiments

[Introduction]: Convective heat transfer data is frequently obtained from transient surface temperature measurements. Thin film resistance gauges, thermocouples, and thermochromic liquid crystals, are used in various situations to measure the surface temperature history. By assuming that uniform semi-infinite flat plate conditions apply, it is possible to express the instantaneous surface heat flux as an analytical function of the transient surface temperature[ll. Various approaches can be used to account for the presence of multi-layered substrates and finite thickness substrate effects (Schultz and Jones; Doorly and Oldfield; Guo et al), however, the effects of surface curvature are usually, neglected. - If the heat transfer data is obtained on the premise that flat plate conditions apply. then error will be introduced if the surface is actually curved. Intuitively, the magnitude of such errors will depend on how far the heat penetrates into the substrate relative to the radius of curvature of the surface. Maulardc4) derived expressions to evaluate the accuracy of the flat plate assumption in cases where the surface under consideration is curved. However, his theoretical results do not provide a convenient means of accurately accounting for surface curvature effects in the routine analysis of experimental data. The current work presents simple analytical curvature corrections for heat transfer results inferred on the assumption that flat plate conditions prevailed during the experiment. Conditions of arbitrary surface heat flux are easily accommodated with the present analysis. The accuracy of the first-order correction analysis is demonstrated by comparing results from the approximate curvature analysis with exact results for a variety of configurations under constant convective heat transfer coefficient conditions. The practical utility of the radial heat conduction modelling is evident from a number of studies in which it has already been employed (Buttsworth and Jones); Hoffs et a1; Fletcher). Nevertheless, data from a recent heat transfer probe experiment is also considered as a further practical demonstration of the present analysis.

The Use of Cardiac Autonomic Responses to Aerobic Exercise in Elderly Stroke Patients: Functional Rehabilitation as a Public Health Policy

Background and purpose: The development of public policies must be guided by full knowledge of the health–disease process of the population. Aerobic exercises are recommended for rehabilitation in stroke patients, and have been shown to improve heart rate variability (HRV). Our aim was to compare the cardiac autonomic modulation of elderly stroke patients with that of healthy elderly people during and after an acute bout of aerobic exercise. Methods: A total of 60 elderly people participated in the study (30 in the control group, mean age of 67 ± 4 years; 30 in the stroke group, mean age of 69 ± 3 years). HRV was analyzed in rest—10 min of rest in supine position; exercise—the 30 min of peak exercise; and recovery—30 min in supine position post-exercise. Results: Taking rest and exercises together, for SDNN, RMSSD, pNN50, RRTri, and TINN, there was no difference between the stroke and control groups (p = 0.062; p = 0.601; p = 0.166; p = 0.224, and p = 0.059, respectively). The HF (ms2) was higher and the LF/HF ratio was lower for the stroke group than the control group (p < 0.001 and p = 0.007, respectively). The SD2 was lower for the stroke group than for the control group (p = 0.041). Conclusion: Stroke patients present reduced variability at rest, sympathetic predominance during exercise, and do not return to baseline after the 30 min of recovery, with similar responses found in the healthy elderly group.
Sustainable UV-Crosslinkable Acrylic Pressure-Sensitive Adhesives for Medical Application

This study aimed to investigate the potential of photoreactive acrylate patches as systems for transdermal drug delivery, in particular, using more renewable alternatives and more environmentally friendly synthesis routes of transdermal patches. Therefore, the aim of this study was to develop a transdermal patch containing ibuprofen and investigate its performance in vitro through the pigskin. Transparent patches were prepared using four acrylate copolymers with an incorporated photoinitiator. Two types of transdermal patches based on the photocrosslinking acrylic prepolymers with isobornyl methacrylate as biocomponent and monomer increasing Tg (“hard”) were manufactured. The obtained patches were characterized for their adhesive properties and tested for permeability of the active substance. It turns out that patches whose adhesive matrix is photoreactive polyacrylate copolymers have a higher cohesion than patches from commercial adhesives, while the modification of the copolymers with isobornyl methacrylate resulted in an improvement in adhesion and tack. This study demonstrates the feasibility of developing photoreactive acrylic-based transdermal patches that contain biocomponents that can deliver a therapeutically relevant dose of ibuprofen.
Online Relative Positioning of Autonomous Vehicles Using Signals of Opportunity

To fully realize the potential of autonomous aerial vehicles, a reliable, robust, and accurate navigation system is required. Current technologies composing such a system include stand-alone and augmented global navigation satellite systems (GNSS), as well as visual, inertial, and signals-of-opportunity (SOPs) approaches. However, as it is well understood that no single alternative can meet the requirements for full autonomy, a combination of technologies is required to address alternative application scenarios. In this work, an online technique for relative positioning of autonomous unmanned aerial vehicles (UAVs) is proposed that capitalizes on SOPs in conjunction with inertial measurements for localization and navigation when GNSS signals are not readily available. The proposed system uses the signals’ characteristics over a large part of the frequency spectrum, in conjunction with an optimal learning (OL) technique, to adaptively choose a sequence of frequencies that provide location estimates in real-time. Subsequently, inertial measurements, which are provided by an onboard unit, are employed to improve on the tracking accuracy. Field experiments, using an autonomous unmanned aerial vehicle, demonstrate the effectiveness of the proposed solution under various parameter settings.
Work Environments and Work Conditions Associated with Stress Symptoms Among Korean Manufacturing Factory Workers

Stress is a primary health promotion issue in worksite research because psychological distress is closely related not only to workers health status but also to their job performance. This study identified the work environment and work condition factors affecting workers stress symptoms among the Korean manufacturing factory workers. A total of 7,818 factory workers employed in 1,562 manufacturing companies participated in the Korean nation-wide occupational health survey conducted by the Korean Occupational Safety and Health Agency in 2003. Participants were selected by the stratified proportional sampling process by standardized industry classification, company size, and locations. Trained interviewers visited the target companies and interviewed the factory workers randomly selected in each company. Work environments included physical work environments (temperature, noise, hazardous organic compounds, and so on) and psychological work environments (job demands, job control, and social support at work), and work conditions included daily working hour, rest time, and so on. Men were 71.5% and the mean age was 34.0 years old. The average working period in the present company was 6.9 years. The average stress score was 26.2 under the perfect score, 50, which means the moderate level of stress. Perceived stress had significant correlations with young age, poor physical work environment, high fatigue, bad perceived health status, and high job demands in Pearson's simple correlation analysis. Perceived health status and perceived fatigue explained 21% variance of stress symptoms and the work environment factor explained 4.8% of that; however, work condition did not have the sufficient effect. In particular, psychosocial work environment variables (job demand, job control, and social support at work) had a clear effect on stress symptoms rather than the physical work environments. Poor perceived health status, severe perceived fatigue, poor physical work environment, high job demands, low social support, heavy alcohol consumption and little exercise were significantly related to high stress symptoms in the Korean manufacturing workers.
