Airline alliance revenue management : improving joint revenues through partner sharing of flight leg opportunity costs

Airlines participating in alliances offer code share itineraries (with flight segments operated by different partners) to expand the range of origin-destination combinations offered to passengers, thus increasing market share at little cost. The presence of code share flights presents a problem for airline revenue management (RM) systems, which aim to maximize revenues in an airline's network by determining which booking requests are accepted. Because partners do not jointly optimize revenues on code share flights, alliance revenue gains from implementing advanced RM methods may be lower than an individual airline's gains. This thesis examines seat availability control methods that alliance partners can adopt to improve the total revenues of the alliance without formally merging. Partners share information about the opportunity costs to their network, called "bid prices", of selling a seat on their own flight leg, a mechanism termed bid price sharing (BPS). Results show that BPS methods often improve revenues and work best for networks with certain characteristics and partners with similar RM systems that exchange recently calculated bid prices as often as possible. Gains are typically only achieved if both alliance partners participate in the code share availability decision (called dual control) rather than one partner only, but implementation of dual control is more difficult for airlines in practice. In the best case scenario, gains of up to . 40% where achieved, which can translate into $120 million per year for the largest airlines. In our simulations, BPS with dual control and frequent bid price calculation and exchange was the only method that produced consistently positive revenue gains in all the scenarios tested. Therefore, alliance airlines must consider the trade off between revenue gains and implementation difficulties of more frequent bid price exchange or dual control. Thesis Supervisor: Peter P.

Snow, buses, and mobile data services

Development and advancement of Information Society1 in on agenda of many nation states today. As scholars, we can contribute to the effort by attempting to reconcile the official rhetoric with the real life situations of “netizens2. This paper is inspired by the publication of Leonard Jessup and Daniel Robey [2002], in which the authors use anecdotes to demonstrate what advanced service possibilities are afforded by ubiquitous technology as contrasted to the residue of social behavior. This story illustrates that the success of establishing Information Society should not be measured by the number of available services to citizens over the wireline and mobile Internet. The ultimate measure for success must be the extent to which people are aware about the availability of relevant content and are using the services [Daniel and Wilson, 2003, p.285].
The safety benefit of continuous narrow painted median strips

Rural highways are typically undivided, have high operating speeds, carry high traffic volumes and are often designed to minimum geometric standards. Head-on and cross-over-the-centreline crashes are of the most severe crash types that occur on rural highways. They are disproportionally represented in crashes resulting in fatalities, yet undivided rural highways provide no separation between opposing traffic lanes. One possible countermeasure to these crash types is a continuous narrow painted median strip. Narrow painted median strips are a relatively new and innovative road safety treatment aimed at reducing the incidence and severity of head-on and crossover-the-centreline crashes on undivided roads. This is achieved by increasing the separation between vehicles travelling in opposite directions and warning drivers that have strayed from their lane with noise and vibration inside the vehicle. Previous research suggests audio-tactile centreline-marking to be an effective countermeasure to these crash types however, the added benefit of combining audio-tactile line-marking with a narrow painted median has notbeen thoroughly evaluated. This research quantifies the safety benefit following installation of a 1.0 m wide continuous painted median strip utilising audio-tactile line-marking on the Bruce Highway in Queensland, Australia. Data was analysed for a 56 km section of the highway before and after installation of the painted median. An Empirical Bayes statistical analysis procedure was used for evaluation due to the short period of before and after data available. This method accounts for the regression to the mean bias that is prevalent when short data collection periods are available or when sites with a higher than normal crash history are being analysed. Findings indicate significant reductions for all crash types that were analysed in this study. Head-on crashes were reduced by 75% (SD = 7.0%), Run-off-road-left crashes were reduced by 59% (SD = 14.5%) and Total crashes were reduced by 59% (SD = 8.8%). The results of this study add to the limited body of knowledge that is published on narrow painted median strips as a road safety treatment. The narrow painted median strip provides significant safety benefits, by means of crash reduction, and has relatively low installation costs. These preliminary yet encouraging results give justification to the future consideration or implementation of a continuous narrow painted median strip as a road safety countermeasure.
Table Grapes Transport Simulation Study by Bardas (Vitis vinifera L.)Cultivar Grown in Karaman Turkey

Table grapes is a second industry in viticulture in Turkey and have been grown in primarily Mediterranean region a popular fruit for local consumption and export to many European and Asian countries as a fresh dessert and for this reason this product has to be transport so long distances for marketing. This simulated export transit experiment with Bardas (Vitis vinifera L.) local table grape cultivar grown in Karaman province was conducted in lab condition Selcuk University Faculty of Agriculture. To produce main knowledge, and to improve the application of resources used to produce, pack, transport, and merchandise Turkish table grapes by increasing efficiency, controlling cost and managing risk throughout the supply chain. In order to develop optimized methods of reducing table grape damage transport stimulatory as vibration stimulator have been used to measure the shocks and vibrations in market bins during 30 min and 60 min transport stimulation. During road transport simulation at 25°C in wooden boxes damages of clusters and berries were measured by laboratory trials to stimulate the events in a controlled and repeatable manner. 3 bins full of fruits were placed onto a vibration table, and during the stimulation three-load profile sensor were placed inside each of bins. While the number of separated berry was determined as a 31.33 in 30 min, the number was 83.10 in vibration period of 60 min. Starting with the beginning the numbers separate resistance of berry, resistance to cracking of berry and elasticity modulus is continuously lowering in 30-60 min vibration periods. The berry separate resistance from cluster were changing between 4.46 N to 1.73 N, and berry cracking resistance were measured between 31.59 N to 26.01 N, and berry elasticity modulus were obtained as between 1423 kPa to 1076.7 kPa. Natural frequency of berry was calculated as on 109.332 Hz that was obtained in of 1.42 m box height.
High voltage LDMOS transistors in sub-micron SOI films

Silicon-on-insulator (SOI) LDMOS transistors with a linearly graded doping profile in the drift region have been found to exhibit both low on-resistance and high breakdown voltage. High-side operation is a problem for devices built in very thin SOI layers due to pinch-off of the drift region. This is less of a problem for devices built in thicker SOI layers. Devices built in thicker SOI films also are more tolerant of manufacturing variations and offer more predictable behaviour. Non-uniform self-heating within the drift region has been measured for the first time. A breakdown voltage of 1020 V is reported for a LDMOS transistor made in a 0.15 /spl mu/m SOI layer.
Analyzing Navy Officer Inventory Projection Using Data Farming

Abstract : The Navy's Strategic Planning and Analysis Directorate (OPNAV N14) uses a complex model to project officer status in the coming years. The Officer Strategic Analysis Model (OSAM) projects officer status using an initial inventory, historical loss rates, and dependent functions for accessions, losses, lateral transfers, and promotions that reflect Navy policy and U.S. law. OSAM is a tool for informing decision makers as they consider potential policy changes, or analyze the impact of policy changes already in place, by generating Navy Officer inventory projections for a specified time horizon. This research explores applications of data farming for potential improvement of OSAM. An analysis of OSAM inventory forecast variations over a large number of scenarios while changing multiple input parameters enables assessment of key inputs. This research explores OSAM through applying the principles of design of experiments, regression modeling, and nonlinear programming. The objectives of this portion of the work include identifying critical parameters, determining a suitable measure of effectiveness, assessing model sensitivities, evaluating performance across a spectrum of loss adjustment factors, and determining appropriate values of key model inputs for future use in forecasting Navy officer inventory.
Gelatinization, Retrogradation and Gel Properties of Wheat Starch–Wheat Bran Arabinoxylan Complexes

Gelatinization, retrogradation and gel properties of wheat starch–wheat bran arabinoxylan (WS–WBAX) complexes have been evaluated. The results of rapid viscosity analyzer (RVA), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) confirmed that WBAX samples with larger Mw and branching degree (HWBAX) significantly impeded gelatinization process of starch by effectively reducing the amount of water available for starch gelatinization. DSC analysis showed that both molecular characteristics and additive amount of WBAX samples have an effect on the long-term retrogradation behavior of starch. For the rheological studies of WS–WBAX mixed gels, the elastic moduli (G’) and shear viscosity of WS–WBAX mixed gels increased with the increase in additive amount of WBAX. WS–HWBAX mixed gels exhibited the lower G’ compared with starch gels containing WBAX with lower Mw and branching degree (LWBAX) at the same amount. The scanning electron micrographs (SEM) revealed that the microstructures of WS–WBAX mixed gels were mainly affected by the amount of WBAX, but hardly by the molecular characteristics of WBAX. Texture profile analysis (TPA) showed that the cohesiveness of fresh WS–WBAX mixed gels became larger with an increase in the WBAX addition amount. The hardness of WS–WBAX mixed gels tended to increase over the 14-day storage.
Clinical characteristics and prognosis of pediatric medulloblastoma: a case study of 40 patients at children’s hospital of Soochow university

Background: To explore the clinical, histological, and molecular characteristics of childhood medulloblastoma (MB) and its prognosis. Methods: The authors analyzed clinical and pathological data from MB patients at Children’s Hospital of Soochow University who were diagnosed by pathology after surgical resection between November 2011 and October 2020. Results: A total of 40 patients were considered (20 males and 20 females), where the median age at MB onset was 81 months (5–163 months). Of these, complete resection was performed for 26 cases (26/40, 65%) and subtotal resection performed for 14 cases (14/40, 35%). Pathology after resection indicated that in 8 cases the MB had already metastasized. All 40 children were histologically classified, identifying: 32 cases of classic type (32/40, 80%), 6 cases of desmoplastic/nodular type (6/40, 15%), and 2 cases of anaplastic type (2/40, 5%). Molecular typing tests were performed on 19 children, identifying: 1 case in the wingless-activated (WNT-activated) group (1/19, 5.3%), 6 cases in the sonic hedgehog-activated (SHH-activated) group (6/19, 31.6%), 7 cases in Group 3 (7/19, 36.8%), and 5 cases in Group 4 (5/19, 26.3%). Of the 40 patients, 29 received a combined treatment of surgery, radiotherapy, and chemotherapy, and the median follow-up time was 25 months (1–102 months). The 3-year overall survival rate (OS) and event-free survival rate (EFS) were (64.3±10.4)% and (61.8±10.3)%, respectively. Univariate analyses showed that age, clinical stage, pathological subtype, and radiotherapy were potentially relevant variables in patient prognosis (P<0.05). Cox regression analysis showed that age and tumor metastasis were independent risk factors for poor prognosis of children with MB (P<0.05). Conclusions: Metastasis and age at initial diagnosis are unfavorable factors in the prognosis of childhood MB patients; however, radiotherapy could improve the prognosis of MB patients. 8
Off-cycle, Real-World Emissions of Modern Light Duty Diesel Vehicles

This paper investigates the emissions performance of modern European light-duty passenger vehicles with turbodiesel engines during real-world driving, notably during two extreme but not uncommon operating regimes: congested urban traffic and high-speed and performance driving. Four cars and one van were tested on a chassis dynamometer and/or on the road with a portable, on-board emissions monitoring system capable of online measurements of particulate and gaseous emissions. On all cars, operation at speeds and acceleration rates in excess to those within the applicable certification NEDC cycle resulted in higher concentrations of nitrogen oxide (NO) and particulate matter (PM). High-speed driving in excess of 120 km/h resulted in a marked increase in NO and PM concentrations, with further increases past 130-140 km/h. In urban driving, highest PM concentrations occurred at the onset of and during accelerations from low rpm. Aggressive, performance driving resulted in substantial increase in NO and PM emissions per kg of fuel compared to normal driving. No marked increases outside of NEDC regimes were, however, observed on the van. The results support the arguments against increase in 130 km/h freeway speed limits and for augmenting the EU certification tests for light diesel vehicles with supplemental cycles or tests.
Informal diffusion of green infrastructure innovations in Indian megacities: perspectives from innovators and potential future adopters

ABSTRACT Five early-stage sustainable urban water management innovations in India are examined utilizing diffusion of Innovations theory. Cases are described using grey literature, surveys, and qualitative insights derived from interviews with innovators (N = 5). Potential future adopters (PFA’s) were also surveyed (N = 31), and their attitudes toward adoption is discussed. We identify alignments and misalignments between the goals, perceptions, adoption attitudes, and modes of communication between innovators and PFA’s. Innovators and PFA’s were largely aligned in their assessment of two innovation characteristics considered ‘most important’ (namely relative advantage and compatibility), but not aligned regarding simplicity (rated ‘most important’) or other ‘moderately important’ to ‘less important’ innovation characteristics (trialability, observability, and reinvention). We identify the role of communication channels between innovators and PFA’s, and suggest that innovators might work to better emphasize the simplicity of their approaches to maximize the likelihood of adoption. Finally, we identify opportunities for future research in this under-studied domain.
From Forensics to Clinical Research: Expanding the Variant Calling Pipeline for the Precision ID mtDNA Whole Genome Panel

Despite a multitude of methods for the sample preparation, sequencing, and data analysis of mitochondrial DNA (mtDNA), the demand for innovation remains, particularly in comparison with nuclear DNA (nDNA) research. The Applied Biosystems™ Precision ID mtDNA Whole Genome Panel (Thermo Fisher Scientific, USA) is an innovative library preparation kit suitable for degraded samples and low DNA input. However, its bioinformatic processing occurs in the enterprise Ion Torrent Suite™ Software (TSS), yielding BAM files aligned to an unorthodox version of the revised Cambridge Reference Sequence (rCRS), with a heteroplasmy threshold level of 10%. Here, we present an alternative customizable pipeline, the PrecisionCallerPipeline (PCP), for processing samples with the correct rCRS output after Ion Torrent sequencing with the Precision ID library kit. Using 18 samples (3 original samples and 15 mixtures) derived from the 1000 Genomes Project, we achieved overall improved performance metrics in comparison with the proprietary TSS, with optimal performance at a 2.5% heteroplasmy threshold. We further validated our findings with 50 samples from an ongoing independent cohort of stroke patients, with PCP finding 98.31% of TSS’s variants (TSS found 57.92% of PCP’s variants), with a significant correlation between the variant levels of variants found with both pipelines.
Absolute position measurement for automated guided vehicles using the Greedy DeBruijn Sequence

Abstract : Automated Guided Vehicles (AGVs) use different techniques to help locate their position with respect to a point of origin. This thesis compares two approaches that utilize a binary track laid on the floor for the AGV to follow. Both approaches use equally spaced n-tuples on the track that the AGV can use to compute its position. Both approaches also have the special feature that every n-tuple on the binary track is unique and can be used to designate the position of an AGV. The first approach, developed by E.M. Petriu, uses a Pseudo-Random Binary Sequence (PRBS) as a model for the binary track. In the second approach, we use a Greedy DeBruijn Sequence (GDBS) as a model for the binary track. Unlike the PRBS model, the GDBS model has a natural ordering which can be used to determine the position of the AGV more quickly and efficiently than the PRBS model.
Comparison of the effects of physical education and sports course for the handicapped on the attitudes of sports science students towards the handicapped

It is an important research topic to what extent the training received by the prospective teachers in order to have positive attitudes towards the handicapped is successful. This study aims to evaluate the effect of physical education and sports course for the handicapped on the attitudes of sports science students towards the handicapped. In the study, the "Attitude Toward Disabled Persons (ATDP) Scale", which was developed by Yuker and Block (1986) and adapted to Turkish by Özyürek (2006), was used as a data collection tool. The reliability coefficient of the scale was . 67-. 83, and the test-retest reliability coefficient was . 76. A total of 76 students from Bülent Ecevit University School of Physical Education and Sports (n = 40) and Düzce University Faculty of Sport Sciences (n = 36) formed the study group who taking physical education and sports courses for the handicapped in the 2017-2018 academic year. The Kolmogorov-Smirnov test and independent samples t-test were used to analyze the data. Descriptive analyzes were conducted to determine the level of attitudes of the participants towards people who were handicapped. As a result of the research, it was determined that the attitude scores of the study group towards the handicapped were higher for the participants whose school type is faculty than those of the college. A difference in other parameters could not be detected.
Predictors of language proficiency in school-age Spanish–English bilingual children with and without developmental language disorder

Abstract Children with developmental language disorder (DLD) have impairments in their language-learning abilities that may influence interactions with environmental opportunities to learn two languages. This study explores relationships between proficiency in L1 and L2 and a set of environmental and personal variables within a group of school-age Spanish–English bilingual children with DLD and a group of typically-developing peers. Within each group, current usage in the home, length of L2 exposure, gender, maternal education, analytical reasoning, and number of L1 conversational partners were used to predict proficiency in each language. Results showed that home language environment, particularly home L2 usage, strongly predicted L1 proficiency but had less influence on the L2. Female gender predicted L1 skills in both groups, whereas analytical reasoning predicted both L1 and L2 but only for children with DLD. This study expands the limited literature on how children with DLD interact with their environment to learn two languages.
COMPARING FACTORS CONDITIONING LANDSCAPE CHANGE DURING VOLCANIC ERUPTION AT VIRUNGA NATIONAL PARK, EAST AFRICA

The change on Virunga National Park (VNP) landscape due to climate change, anthropogenic activities and natural disasters calls for appropriate monitoring and management policies. This study aimed to assess and compare the factors conditioning landscape change during volcanic eruption at VNP located in the East Africa from 1990 to 2018. Land use and land cover Landsat 5 images of 1990 and 2004, and Landsat 8 images of 2018 were analyzed by the supervised maximum likelihood classification techniques. The calculation of Normalized Difference Vegetation Index (NDVI) and its relationship with precipitation and temperature referred to the same images. Remote Sensing (RS) and Geographic Information System (GIS) facilitated data analysis. The results highlighted human activities as key drivers to landscape changes recorded in the central and northern parts. The southern part recorded high extent of changes which transformed 8.36 Km of the park into new lava flow linked to 11.6 Km of grassland and almost 1 Km of shrubland changed into lava plains. The two volcanoes are associated with volcanic plume and gas emission, which mainly cause NDVI perturbation. This study can serve as a baseline in the conservation and management of protected areas and reduction of volcanic effects on national parks.
Experiments on Laser Beam Jitter Control with Applications to a Shipboard Free Electron Laser

Abstract : A Free Electron Laser (FEL) shows potential as an effective defensive weapon for a naval ship against today s modern weapons such as supersonic anti-ship missiles. A laser can destroy these fast and highly maneuverable missiles at the speed of light. Several obstacles must be overcome to employ this weapon on a naval ship. This thesis discusses several methods for passive and active jitter control of a guided optical beam which might be employed in a FEL weapon system. Vibration experiments were performed on the Laser Jitter Control Testbed at the Naval Postgraduate School to test several types of feedback and adaptive feedforward controllers. A Filtered-X Recursive Least Squares (FXRLS) adaptive feedforward controller was found to be most effective to correct a combination of both broadband and narrowband disturbances. The FXRLS controller results in a 33 dB decrease in jitter caused by a 50 Hz narrowband vibration and an 89% improvement in low frequency broadband jitter experienced by the optical beam. A proposed Free Electron Laser design employing both passive and active vibration control techniques is recommended that employs a co-linear optical reference beam for jitter control.
