3D-high efficiency video coding (3D-HEVC) is the next-generation compression standard for multiview system applications, which has recently been approved by MPEG and VCEG as an extension of HEVC. To improve the compression efficiency of depth map, several compression tools have been developed for a better representation depth edges. These supplementary coding tools together with existing prediction modes can achieve high compression efficiency, but require a very high complexity that restricts the encoders from ongoing application. In this paper, we introduce a fast scheme to reduce complexity of depth coding in inter and intramode prediction procedure. A simulation analysis is performed to study intra and intermode distribution correlations in the depth compression information. Based on that correlation, we exploit two complexity reduction strategies, including early SKIP and adaptive intra prediction selection. Experimental results demonstrate that our scheme can achieve a complexity reduction up to 63.0%, without any noticeable loss of compression efficiency.

Recent considerations of steam and air mixture dynamics in operating condensers has led to a more thorough understanding of how condenser performance is affected by air in-leakage. Results of this model-based theoretical description, which are in agreement with measurement data from operating condensers, are reviewed and used to propose beneficial design features for new and re-tubed condenser assemblies. It is anticipated from this work, that condensers can be designed which significantly reduce the amount of dissolved oxygen in condensate from locations of free air ingress above the hotwell level. This reduction also applies to other undesirable noncondensables that enter condensate driven by the same mechanism contributing to dissolved oxygen. When air in-leakage becomes sufficiently high, it contributes to excess back pressure on the turbine. In this region of high air in-leakage, the amount of dissolved oxygen can become very high. The design therefore, minimizes or eliminates the corrosive effects of air inleakage, both high and low, which is particularly important during periods of high demand when load must be maintained.

Abstract Rainwater harvesting is an ancient practice aiming to cover water needs for domestic, irrigation and livestock uses. In this study, the rainwater harvesting tank size was investigated to meet five water-need levels of a mixed goat–sheep farm using a daily water balance method. This method was applied using daily rainfall data for a period of 16 years from six meteorological stations in selected regions of Greece, characterized by different rainfall regimes and well-developed livestock activity, taking into account, among other parameters, the water needs of animals, the rainwater collection area and the runoff coefficient. There is a great variation in the rainwater harvesting tank size among the stations studied due to differences in the annual rainfall and the maximum dry period. Results showed that meeting full demands (100% reliability) requires tank sizes ranging from 20 m3 for short dry period stations–low demand scenario (320 L/day) to 115 m3 for long dry period stations–high demand scenario (576 L/day), assuming a maximum collection area of 450 m2. Correspondingly, reliability analysis showed that very high values of reliability (95%) can be obtained with tank sizes ranging from 10 to 85 m3, respectively.

Sleep disorders are very frequent in the elderly and it affects health and well-being of older people. Some authors estimate that the prevalence of insomnia in the elderly is very high, close to 60%. Sleep disorders in the elderly are frequent and it causes high demand for care. Some authors think that it will affect a lot in health of older people and those who take care of them. This could bring an increase of institutionalization. With this work we wanted to measure prevalence of insomnia in those chronic and psychogeriatric patients who are in nursing-homes, and which psychotropic drugs are prescribed for control it. In addition, we have studied if there is significant relationship between psychiatric diagnosis, neurologic diagnosis, age or sex, medical comorbidity, and the presence of insomnia.

Screw piles need to be upscaled for offshore use e.g. being an alternative foundation and anchor form for offshore floating wind turbines, although the high demand of vertical installation forces could prevent its application if conventional pitch-matched installation is used. Recent studies, using numerical and centrifuge physical tests, indicated that the vertical installation force can be reduced by adopting over-flighting which also improved axial uplift capacity of the screw pile. The current study extends the scope to axial cyclic performance with respect to the installation approach. Using quasi-static discrete element method (DEM) simulation it was found that the over-flighted screw pile showed a lower displacement accumulation rate, compared to a pitch-matched installed pile, in terms of load-controlled cyclic tests. Sensitivity analysis of the setup of the cyclic loading servo shows the maximum velocity during the tests should be limited to avoid significant exaggeration of the pile displacement accumulation but this may lead to very high run durations.

The market is always changing and increasing competition. In this condition, the hotel needs to improve responsiveness to the environment to service. Hotels should be able to establish a policy with the best results. Yield management offers a concept for each hotel is able to put himself in the best position in the changing environment. Revenues need to be managed well for a more popular method is called yield management or revenue management Currently, yield management, has become a very important innovation in the hospitality industry. The main objective of yield management is to maximize the occupancy room and at the same price achieved average room rate is high. The rooms are the same product, but have different market segments, both used by the guest or guest tours individual. Each market segment may be subject to different prices for the same period. Demand for each segment in the future, have a fairly high level of uncertainty in thiscase, management does not know how much and when the individual guest is coming. Individual guest room reservations typically do on arrival or a few days prior to say, while guest tour groups generally pay full price and keep the rooms are not already sold to the tourist gueist at cheap prices or discounts. Profit oriented hotel management and have broad freedom of action to increase revenue at the optimum level of demand for rooms is very high. This is to compensate low income or cover losses in the period of very Iow occupancy rates, where rooms are sold at discount in nearly all segments. Room sales management to achieve optimum opinions need to plan how many rooms are sold at a discount and how many rooms were sold at full price. In addition . to avoid loss of revenue due to cancellation of booking rooms during periode of high demand for rooms, management needs to accept room reservations exceeds the number of rooms available for sale

This paper presents an analysis of design team characteristics and design activities that are significantly associated with design outcomes (i.e., project performances) in sophomore-level project-based design courses. Besides efficient team work, a team needs to successfully perform three design activities: concept generation, concept selection, and prototyping. In the design course, teams are formed based on students’ choice of teammates as well as on instructor assigned teams which maximize cognitive mode diversity among members. A regression analysis is performed to find variables that are significantly associated with design outcomes. These variables include team size, teaming preference, diversity of cognitive modes among team members, the average number of power tools team members have used in the past, whether or not a team experienced a team-working difficulty, the number of concepts generated before and after using creativity techniques, whether or not a team had the most successful strategy (called “winning” concept in this study) in a set of concepts from which one concept is chosen for prototyping, and timing of selecting the winning concept (at concept selection, at proof-of-concept testing, or at final testing). Design strategies used by teams, the winning concepts, results of regression analysis (variables significantly associated with design outcomes) are discussed.

Abstract As part of the curriculum for a manufacturing program at Stanford, a Ph.D.-level course covering life-cycle design (also referred to as design for “X”) issues is required to be taken by students in the program. As a Ph.D. candidate doing research in this area, the first author (Martin) was asked to develop and teach this course. This paper discusses some of the issues in creating a new course and describes the use of structured methodologies (affinity diagrams, customer surveys, benchmarking, concept generation, and concept selection) in developing the course. Our goal in this paper is threefold: 1) to give an example of the use of structured methodologies in developing a course, 2) to show a sample curriculum for a dfX course, and 3) to present a framework describing course development.

Iron is an essential nutrient for the legume-rhizobia symbiosis and nitrogen-fixing bacteroids within root nodules of legumes have a very high demand for the metal. Within the infected cells of nodules, the bacteroids are surrounded by a plant membrane to form an organelle-like structure called the symbiosome. In this review, we focus on how iron is transported across the symbiosome membrane and accessed by the bacteroids.
