Consumer perceptions of meat quality and shelf-life in commercially raised broilers compared to organic free range broilers

Summary Consumers in the United States are increasingly interested in both free-range and organic chicken. Therefore, the objectives of this research were to compare eating quality and shelf-life of meat from organic free range broilers to meat from commercially raised broilers. No significant differences in breast fillet tenderness or proximate composition were noted between the two treatments. Free-range chicken breasts were significantly larger (153 g) than commercial chicken breasts (121 g). Breast fillets from the free range birds had higher pH values (5.96 vs. 5.72 respectively) and were darker (49.14 vs. 53.46, respectively) than fillets from the commercially raised birds. Initial TBARS (day 0) were significantly higher for the commercially raised broiler breast fillets (4.96 vs. 3.07 mg malonaldehyde/kg), but by day 3 of refrigerated storage the level of oxidation was similar. Free range fillets had significantly higher APC and coliform counts and exhibited signs of spoilage earlier than commercial fillets. Consumers evaluated breast fillets, using a ranking test (1-least intense to 5-most intense) and the resultant data was analyzed using Kruskal-Wallis. Consumers found no difference in fillet juiciness, tenderness or flavour (P>0.05). Commercial breast fillets, however, were preferred over the free-range fillets (P<0.05). Trained panellists evaluated drums finding no difference in tenderness or flavour, but meat from free range birds was juicier and had stronger attachment of the meat to the bone. Commercial and free-range chicken had many similarities in meat quality and sensory attributes, but meat from free-range poultry had a shorter shelf life than meat from commercially raised chickens.
The Development of a Kernel to Detect Ziphius cavirostris Vocalizations and a Performance Assessment of an Automated Passive Acoustic Detection Scheme

Abstract : An ensemble consisting of 150 Ziphius cavirostris vocalizations was compiled from acoustic data recorded at two High-frequency Acoustic Recording Package (HARP) locations: the Naval Postgraduate School (NPS)'s Point Sur HARP and Scripps Institution of Oceanography (SIO)'s site H HARP. The ensemble was analyzed via a principal component analysis (PCA). The results of the PCA verified the statistical robustness of the signal and yielded one dominant mode which accounted for 73% of the variance. The dominant mode was used to create a kernel for a matched filter detection scheme. The subsequent detector output was statistically evaluated against a ground truth. The ground truth identified 28,434 Ziphius clicks by visually inspecting over 170 minutes of data recorded by NPS s Data Acquisition System (DAS) at the Southern California Offshore Range (SCORE). The inability to visually discriminate a signal embedded in noise created a conservatively biased ground truth estimate which increased the detector s false alarm rate. At an acceptable 0.1% false alarm rate, the detector had an overall 44% probability of detection. A further assessment of the detector s performance divided the data into two categories: cluttered and uncluttered. At a false alarm rate of 0.1%, the probability of detection was 26% and 61%, respectively.
Nutritional Predictors of Mortality after Discharge in Older Patients with type 2 Diabetes

Background: Older patient with type 2 diabetes (T2D) and malnutrition have a greater chance of negative events during hospitalization and a higher risk of mortality. The aim of this study was to investigate nutritional markers as mortality predictors following discharge hospitalized older patients with T2D. Methods: This is a prospective cohort study with follow-up of four years. All patients were subjected to Mini Assessment Nutrition, Subjective Global Assessment, calf circumference, arm circumference and adductor pollicis muscle thickness, obtained all within 48 h of admission. Mortality data were verified by medical registry and analyzed using Cox-proportional hazard models and survival curves. Results: 311 patients were included; the mean age was 71.35 years. There were 113 (36.3 %) deaths in the follow-up period. Nutritional status evaluated according to BMI identified 54.5% (n = 168) were overweight, for other hand the MAN identified 45.7% of patients were at risk of malnutrition and 37.7% malnutrition and the SGA identify 61.7% (n = 192) presented normal nutrition in admission. Malnutrition patients (OR=2.02), with low calf circumference (OR=1.43) or with APMT less than 5th percentile (2.33) were associated with post-discharge mortality. Conclusion: Malnutrition, reduced calf circumference and reduced APMT were nutritional predictors of mortality after hospital discharge in older patients with diabetes
Joint Processing of Spatial Resolution Enhancement and Spectral Unmixing for Hyperspectral Image

Spatial resolution enhancement and its subsequent tasks are always separated in conventional hyperspectral image (HSI) processing model. The requirement of the following task, such as unmixing, cannot be referred by spatial resolution enhancement. Moreover, errors and artifacts will also be transmitted and accumulated. In this work, we propose a joint processing method of spatial resolution enhancement and spectral unmixing for HSI (J-SRE-Un), where these two tasks are treated as constraints for each other to simultaneously achieve better performance. Experiments on both simulated and real data demonstrate the effectiveness and superiority of our method.
Algorithms of Scheduling Aircraft Landing Problem

This thesis addresses the problem of scheduling aircraft landings at an airport. Given a set of planes and runways, the objective is to minimize the total (weighted) deviation from the target landing time for each plane. There are costs associated with landing either earlier or later than a target landing time for each plane. Each plane has to land on one of the runways within its predetermined time windows such that separation criteria between all pairs of planes are satisfied. This type of problem is a large-scale optimization problem, which occurs at busy airports where making optimal use of the bottleneck resource (the runways) is crucial to keep the airport operating smoothly. This thesis is the first attempt to develop a branch-and-price exact algorithm for the Aircraft Landing Problem (ALP), in which the column generation method is applied to solve the linear relaxation problem for each branch node throughout the branch-and-bound procedure. We formulate the ALP as a set partitioning problem with side constraints on the number of available runways. We also present a mixed integer formulation for the subproblem in column generation, which can be used to generate the columns with the minimum negative reduced cost. Then a branch-and-bound method is developed to find the optimal integer solution for the ALP. Finally, the branch-and-price exact algorithm is implemented and tested on the public data from OR Library involving up to 50 aircraft and 4 runways. The computational results show that the algorithm can solve the problem optimally in acceptable CPU time. Furthermore, the optimal solutions can be achieved with less than 500 columns generated and 12 branch nodes explored.
Stabilizing Control System of a Platform of a Buoy for Offshore Wind Assessment

The purpose of this project is to design a control system to stabilize a platform on a buoy. Stabilization of the platform on the buoy is needed for reliable measurements of wind speed and wind direction on sea using LiDAR (Light Detection And Ranging) modules. These modules use the reflection of particles in the air to measure the wind speed and wind direction. This report is a description of the design of a prototype for a buoy with a stabilized platform. The research contains a study on the behavior of a buoy on waves, a description of the choices made for the design, a description of the used test methods, the test results and some recommendations for improvements on the design, based on the test results. The platform is controlled by three linear actuators of adjustable length. The angle of tilt of the platformis measured with a gyroscope and is used for controlling the linear actuators. The platform is able to compensate an angle of tilt that is smaller than 38° . The reaction time on deviations that are smaller than 10° is less than 1.2 seconds. The reliability on the long term must be improved, through implementation of some recommendations. One of these recommendations is the use of a Kalman filter to prevent long term drift of sensor output by combining different kinds of sensors.
The Rationale for CAD-CAM Uncemented Custom Hips: An Interim Assessment

The purpose of this paper is to examine whether the rationale for CAD-CAM Custom Hips is realised in clinical practice. Previous studies demonstrated that custom uncemented stems, with a close fit proximally and a sliding fit distally, produced stresses closer to normal than for other stem types, which should result in the preservation of proximal bone. Custom stems showed less micromotion, especially in torsional loading, and hence should demonstrate interface osseointegration. The hips are designed and manufactured using specially written software. The standard design includes proximal macro-grooves with HA coating, an anterior flare, a lateral flare, a collar, and a smooth distal stem for a sliding fit. Elective features are added such as proximal stem twist and neck retroversion in CDH, increased stem length to bypass defects, curvatures in AP and ML views, and distal cutting flutes when extra torsional stability is required. From 1989 to 1994, 411 cases were carried out, approximately one-third in each of the categories of OA, JCA/CDH, and revision. Studies were made of the available radiographs at yearly intervals, while DEXA scans were taken of the RNOHT patients pre-operatively, at 6 months and then yearly. There were four failures requiring revision, three of the early primary design without HA coating, and one a revision design. The radiographs in primary hips showed complete proximal bone-implant apposition in 81% of all cases. The DEXA scans showed that the mean bone mass after two years for all seven Gruen zones was greater than 90%. It was concluded that the CAD-CAM HA-coated Custom Hips showed bone and interface stability up to this time. The hip has played a useful role in providing the ideal stem for each particular case, which may result in an improvement of long-term results, compared with the use of off-the-shelf implants.

A Fully Integrated Multi-Band Multi-Output Synthesizer with Wide-Locking-Range 1/3 Injection Locked Divider Utilizing Self-Injection Technique for Multi-Band Microwave Systems

This dissertation reports the development of a new multi-band multi-output synthesizer, 1/2 dual-injection locked divider, 1/3 injection-locked divider with phase-tuning, and 1/3 injection-locked divider with self-injection using 0.18-micrometer CMOS technology. The synthesizer is used for a multi-band multi-polarization radar system operating in the K- and Ka-band. The synthesizer is a fully integrated concurrent tri-band, tri-output phase-locked loop (PLL) with divide-by-3 injection locked frequency divider (ILFD). A new locking mechanism for the ILFD based on the gain control of the feedback amplifier is utilized to enable tunable and enhanced locking range which facilitates the attainment of stable locking states. The PLL has three concurrent multiband outputs: 3.47-4.313 GHz, 6.94-8.626 GHz and 19.44-21.42-GHz. High second-order harmonic suppression of 62.2 dBc is achieved without using a filter through optimization of the balance between the differential outputs. The proposed technique enables the use of an integer-N architecture for multi-band and microwave systems, while maintaining the benefit of the integer-N architecture; an optimal performance in area and power consumption. The 1/2 dual-ILFD with wide locking range and low-power consumption is analyzed and designed together with a divide-by-2 current mode logic (CML) divider. The 1/2 dual-ILFD enhances the locking range with low-power consumption through optimized load quality factor (QL) and output current amplitude (iOSC) simultaneously. The 1/2 dual-ILFD achieves a locking range of 692 MHz between 7.512 and 8.204 GHz. The new 1/2 dual-ILFD is especially attractive for microwave phase-locked loops and frequency synthesizers requiring low power and wide locking range. The 3.5-GHz divide-by-3 (1/3) ILFD consists of an internal 10.5-GHz Voltage Controlled Oscillator (VCO) functioning as an injection source, 1/3 ILFD core, and output inverter buffer. A phase tuner implemented on an asymmetric inductor is proposed to increase the locking range. The other divide-by-3 ILFD utilizes self-injection technique. The self-injection technique substantially enhances the locking range and phase noise, and reduces the minimum power of the injection signal needed for the 1/3 ILFD. The locking range is increased by 47.8 % and the phase noise is reduced by 14.77 dBc/Hz at 1-MHz offset.

The views and opinions of authors expressed herein do not necessarily state or reflect those of the United States government or any agency thereof. This report summarizes the offshore wind resource potential, based on map estimates, for the contiguous United States and Hawaii, as of May 2009. The development of this assessment has evolved over multiple stages as new regional meso-scale assessments became available, new validation data were obtained, and better modeling capabilities were implemented. It is expected that further updates to the current assessment will be made in future reports. Offshore wind energy development promises to be a significant domestic renewable energy source, especially for coastal energy loads with limited access to interstate grid transmission. The definition of the magnitude and distribution of this resource required the development of a standard and flexible database. Developed using Geographic Information System (GIS) techniques, the database includes offshore wind resource characteristics such as wind speed, water depth, and distance from shore. It combines the resource characteristics with state administrative areas and quantifies the resource for several scenarios. In the future, the database may be expanded to include other important characteristics such as wave power density, extreme wind and wave, ocean currents, and a number of other parameters important to the design of offshore wind turbines. The primary method used to present the offshore wind resource data are maps that categorize the resource by annual average wind speed at 90 meters (m) above the surface. The resource maps extend from the shoreline out to 50 nautical miles (nm) offshore. Exceptions to the 50 nm mapped distance are the Great Lakes that were mapped in their entirety for the offshore resource and Massachusetts, where the computed resource did not extend 50 nm from the edge of …
