Development of an online application form and database for Indiana businesses who apply for the AchieveWELL certificate through the Wellness Council of Indiana

The purpose of this creative project was to develop an electronic form to be used by businesses that apply for the AchieveWELL certification in Indiana through the Wellness Council of Indiana (WCI). To be eligible to receive an AchieveWELL certificate, each workplace must meet criteria for 11 specific components. At this time, however, there is no formal application process for wellness programs to utilize, making the determination of eligibility problematic for the WCI and the application process confusing for the worksites attempting to become certified. An electronic form will make the process more efficient for the applicant and reviewing committee and help WCI reach their certification goals while concomitantly providing up-to-date data on the health of Indiana businesses. The electronic form will abstract and store key components in a companion data source, allowing future data analysis and tracking of the AchieveWELL companies. To create the electronic form, this researcher: 1) completed training for the Adobe interactive form software; 2) engaged in conversation with WCI leaders and stakeholders to become fully entrenched in the nuances of the project, 3) and developed the online electronic template for the AchieveWELL certificate application form and database.Thesis (M.A.)Department of Family and Consumer Science

Novel extra-thoracic VATS minimally invasive technique for management of multiple rib fractures.

We report an elderly patient with chronic obstructive pulmonary disease (COPD), Alzheimer\u27s disease and early dementia who presented with multiple displaced rib fractures of left ribs 4 through 9 with flail segments of ribs 4 through 8 and an associated traumatic pneumatocele from rib puncture of the left upper lobe. The decision to treat this patient operatively was based on the presence of flail chest, the patient\u27s age, baseline co-morbidities and limited physiological reserve. Surgical rib fixation is traditionally performed with a thoracotomy incision and open exposure for extra-thoracic rib fixation, however, this patient underwent chest wall stabilization using an extra-thoracic video-assisted thoracic surgery (VATS) technique. We discuss our operative technique using universal rib plating system, optimal retraction for exposure and use of balloon dilation to create an accessible extra-thoracic working space. This surgical approach provided a faster recovery to this patient\u27s baseline with minimal use of narcotics thereby highlighting the impact and importance of this surgical technique for patients presenting with multiple fib fractures, especially the elderly. We show that VATS assisted minimally invasive technique for operative management of multiple rib fractures is a viable surgical option demonstrated by this patient\u27s recovery and return to function with minimal need for pain control despite her advanced age and baseline co-morbidities

Rate of photosynthetic induction in fluctuating light varies widely among genotypes of wheat.

Crop photosynthesis and yield are limited by slow photosynthetic induction in sunflecks. We quantified variation in induction kinetics across diverse genotypes of wheat for the first time. Following a preliminary study that hinted at wide variation in induction kinetics across 58 genotypes, we grew 10 genotypes with contrasting responses in a controlled environment and quantified induction kinetics of carboxylation capacity (Vcmax) from dynamic A versus ci curves after a shift from low to high light (from 50 µmol m-2 s-1 to 1500 µmol m-2 s-1), in five flag leaves per genotype. Within-genotype median time for 95% induction (t95) of Vcmax varied 1.8-fold, from 5.2 min to 9.5 min. Our simulations suggest that non-instantaneous induction reduces daily net carbon gain by up to 15%, and that breeding to speed up Vcmax induction in the slowest of our 10 genotypes to match that in the fastest genotype could increase daily net carbon gain by up to 3.4%, particularly for leaves in mid-canopy positions (cumulative leaf area index ≤1.5 m2 m-2), those that experience predominantly short-duration sunflecks, and those with high photosynthetic capacities

Determining lake surface water temperatures worldwide using a tuned one-dimensional lake model (FLake, v1)

A tuning method for FLake, a one-dimensional (1-D) freshwater lake model, is applied for the individual tuning of 244 globally distributed large lakes using observed lake surface water temperatures (LSWTs) derived from along-track scanning radiometers (ATSRs). The model, which was tuned using only three lake properties (lake depth, snow and ice albedo and light extinction coefficient), substantially improves the measured mean differences in various features of the LSWT annual cycle, including the LSWTs of saline and high altitude lakes, when compared to the observed LSWTs. Lakes whose lake-mean LSWT persists below 1 °C for part of the annual cycle are considered to be seasonally ice-covered. For trial seasonally ice-covered lakes (21 lakes), the daily mean and standard deviation (2σ) of absolute differences between the modelled and observed LSWTs are reduced from 3.07 °C ± 2.25 °C to 0.84 °C ± 0.51 °C by tuning the model. For all other trial lakes (14 non-ice-covered lakes), the improvement is from 3.55 °C ± 3.20 °C to 0.96 °C ± 0.63 °C. The post tuning results for the 35 trial lakes (21 seasonally ice-covered lakes and 14 non-ice-covered lakes) are highly representative of the post-tuning results of the 244 lakes. For the 21 seasonally ice-covered lakes, the modelled response of the summer LSWTs to changes in snow and ice albedo is found to be statistically related to lake depth and latitude, which together explain 0.50 (R2adj, p = 0.001) of the inter-lake variance in summer LSWTs. Lake depth alone explains 0.35 (p = 0.003) of the variance. Lake characteristic information (snow and ice albedo and light extinction coefficient) is not available for many lakes. The approach taken to tune the model, bypasses the need to acquire detailed lake characteristic values. Furthermore, the tuned values for lake depth, snow and ice albedo and light extinction coefficient for the 244 lakes provide some guidance on improving FLake LSWT modelling

An efficient adaptive fusion scheme for multifocus images in wavelet domain using statistical properties of neighborhood

In this paper we present a novel fusion rule which can efficiently fuse multifocus images in wavelet domain by taking weighted average of pixels. The weights are adaptively decided using the statistical properties of the neighborhood. The main idea is that the eigen value of unbiased estimate of the covariance matrix of an image block depends on the strength of edges in the block and thus makes a good choice for weight to be given to the pixel, giving more weightage to pixel with sharper neighborhood. The performance of the proposed method have been extensively tested on several pairs of multifocus images and also compared quantitatively with various existing methods with the help of well known parameters including Petrovic and Xydeas image fusion metric. Experimental results show that performance evaluation based on entropy, gradient, contrast or deviation, the criteria widely used for fusion analysis, may not be enough. This work demonstrates that in some cases, these evaluation criteria are not consistent with the ground truth. It also demonstrates that Petrovic and Xydeas image fusion metric is a more appropriate criterion, as it is in correlation with ground truth as well as visual quality in all the tested fused images. The proposed novel fusion rule significantly improves contrast information while preserving edge information. The major achievement of the work is that it significantly increases the quality of the fused image, both visually and in terms of quantitative parameters, especially sharpness with minimum fusion artifacts

Human-mobility-based sensor context-aware routing protocol for delay-tolerant data gathering in multi-sink cell-phone-based sensor networks

Ubiquitous use of cell phones encourages development of novel applications with sensors embedded in cell phones. The collection of information generated by these devices is a challenging task considering volatile topologies and energy-based scarce resources. Further, the data delivery to the sink is delay tolerant. Mobility of cell phones is opportunistically exploited for forwarding sensor generated data towards the sink. Human mobility model shows truncated power law distribution of flight length, pause time, and intercontact time. The power law behavior of inter-contact time often discourages routing of data using naive forwarding schemes. This work exploits the flight length and the pause time distributions of human mobility to design a better and efficient routing strategy. We propose a Human-Mobility-based Sensor Context-Aware Routing protocol (HMSCAR), which exploits human mobility patterns to smartly forward data towards the sink basically comprised of wi-fi hot spots or cellular base stations. The simulation results show that HMSCAR significantly outperforms the SCAR, SFR, and GRAD-MOB on the aspects of delivery ratio and time delay. A multi-sink scenario and single-copy replication scheme is assumed

Chip equalized adaptive rake receiver for DS-CDMA UWB systems

Conventional Rake receiver is a popular and effective method of utilizing the diversity offered by a DS-CDMA and multipath communication channel. The proposed Rake receiver is useful for suppression of multiple access interference in a multipath channel. The receiver works on chip level equalization on each Rake finger to cancel multi-access interference. Simulation results show that the convergence, diversity gain and bit error probability performance of the proposed receiver is much better than conventional adaptive Rake receiver in multipath channels
