To tackle the issue in deep crowd sensing, a Time and Location Correlation Incentive (TLCI) scheme is proposed for deep data gathering in crowdsourcing networks. In TLCI scheme, a metric named “Quality of Information Satisfaction Degree” (QoISD) is to quantify how much collected sensing data can satisfy the application’s QoI requirements mainly in terms of data quantity and data coverage. Two incentive algorithms are proposed to satisfy QoISD with different view. The first algorithm is to ensure that the application gets the specified sensing data to maximize the QoISD. Thus, in the first incentive algorithm, the reward for data sensing is to maximize the QoISD. The second algorithm is to minimize the cost of the system while meeting the sensing data requirement and maximizing the QoISD. Thus, in the second incentive algorithm, the reward for data sensing is to maximize the QoISD per unit of reward. Finally, we compare our proposed scheme with existing schemes via extensive simulations. Extensive simulation results well justify the effectiveness of our scheme. The QoISD can be optimized by 81.92%, and the total cost can be reduced by 31.38%.

The vehicular communication networks, which can employ mobile, intelligent sensing devices with participatory sensing to gather data, could be an efficient and economical way to build various applications based on big data. However, high quality data gathering for vehicular communication networks which is urgently needed faces a lot of challenges. So, in this paper, a fine-grained data collection framework is proposed to cope with these new challenges. Different from classical data gathering which concentrates on how to collect enough data to satisfy the requirements of applications, a Quality Utilization Aware Data Gathering (QUADG) scheme is proposed for vehicular communication networks to collect the most appropriate data and to best satisfy the multidimensional requirements (mainly including data gathering quantity, quality, and cost) of application. In QUADG scheme, the data sensing is fine-grained in which the data gathering time and data gathering area are divided into very fine granularity. A metric named “Quality Utilization” (QU) is to quantify the ratio of quality of the collected sensing data to the cost of the system. Three data collection algorithms are proposed. The first algorithm is to ensure that the application which has obtained the specified quantity of sensing data can minimize the cost and maximize data quality by maximizing QU. The second algorithm is to ensure that the application which has obtained two requests of application (the quantity and quality of data collection, or the quantity and cost of data collection) could maximize the QU. The third algorithm is to ensure that the application which aims to satisfy the requirements of quantity, quality, and cost of collected data simultaneously could maximize the QU. Finally, we compare our proposed scheme with the existing schemes via extensive simulations which well justify the effectiveness of our scheme.

Seismic Images

Seismic acquisition has undergone a revolution over the last few decades. The volume of data acquired has increased exponentially, and the quality of seismic images obtained has improved tremendously. While the total cost of acquiring a seismic survey has increased, the cost per trace has dropped precipitously. Land surveys have evolved from sparse 2D lines acquired with a few dozen receivers to densely sampled 3D multiazimuth surveys. Marine surveys that once may have consisted of a small boat pulling a single cable have evolved to large streamer vessels pulling multiple cables and air-gun arrays and to ocean-bottom detectors that require significant fleets to place the detectors, shoot the sources, and provide support. These surveys collect data that are wide azimuth and typically fairly well sampled.

Quincunx Sampling

Subpixel technique of linear CCD is effective to enhance the spatial resolution without increasing the focal length of optics and reducing the pixel size. To compare image quality of two main subpixel imaging modes, quincunx sampling and four-point sampling, a method to quantitatively evaluate image quality of subpixel based on MTF was proposed. The MTF of quincunx and four-point sampling modes were derived. Analytical results shows that theoretical limiting resolution of quincunx sampling and four-point sampling is improved to 1.4 and 1.86 times respectively, and MTF values at Nyquist frequency of two modes are increased by 0.1106 and 0.1679, respectively. MTFA in (0, 0.5) of two subpixel imaging modes were calculated and results illustrates that four-point sampling offers much more improvement with image quality than quincunx sampling, at the cost of double amount of data. A model for simulating subpixel imaging using Matlab was established, and simulation results of spoke target verify the theoretical analysis.

This research aimed to study the cost potential of shallot in Rasi Salai District, Sisaket Province in order to lead to planning on pricing, marketing, improving the quality of shallot and analyzing data of farmers and shallot production. The research findings on the general information of shallot farmers revealed that they consisted of 75% of males and 25% of females with 40-49 years of age or 50%. Most of their educational levels were 55% of primary level or lower. They grew shallot together with other crops. The Bang Chang varieties (local shallot varieties of Sisaket Province) were grown most of 75% and the other 25% of local northern verities called Hom Bua. The 70% of planting shallots were harvested from the last season and the other 30% were purchased from other farmers in the market.  The shallot productivity per rai was uncertain depending on the caring, fertilizing and disturbing disease. Approximately 35% of the farmers harvested 1,200-1,500 kilograms per rai or 25%. Regarding the production cost of shallot, it was found that the average mount was 8,151.5 baht per rai with the highest amount of verities of 3,250 baht per rai or 15.2%. The cost of insecticide was 1,000 baht or 10.2% of the total cost. In addition, the least cost was transportation for 3.3% only because most merchants bought shallots at the farming sites.  According to sale data, 70% of the farmers sold local verieties of Sisaket Province with average price of 30 baht per kilogram, followed by 15% of Hom Bua with an average price of 45 baht per kilogram. The average income earned by farmers in each household was different at 20,001-25,000 baht per rai

Depreciation Methods

This paper proceeds as follows. Depreciation expense, which will directly relate to the size of the product costs, profits and taxes, is being widely concerned. A great number of people are particularly interested in the accurate depreciation of the costs of fixed assets. Different kinds of fixed assets bring economic benefits for the enterprise in completely different ways so that they should adopt different depreciation methods. The Enterprise Accounting Standards of China stipulated that if the companies increase fixed assets during the month, there will be no depreciation expense this month. But I disagree with this rule which violates the requirement of accounting the quality of information in reliability and authenticity. We should accurately calculate the depreciation expenses by the time, since then the depreciation expense can be accurate to a day. Strengthening the depreciation of fixed assets to precise management is imperative. Precise depreciation management not only helps to control the cost strictly, but also can strengthen management and promote the enterprise to develop sustainably.

Operative care is one of the major areas of healthcare services as over 310 million surgeries are conducted yearly. Surgery cancellations is a widely used indicator when evaluating the quality of preoperative care. Cancellations cause financial lost for organizations, however there is only limited research about the costs. The aim of this study was to evaluate the cost of elective day of surgery (DOS) cancellations in 13 operative specialties at a university hospital in Finland between September 1, 2015 and May 31, 2016 after a structured preoperative protocol was implemented to practice and a cancellation rate of 4.7% was recognized. Procedure prices conducted the data for the research and were collected from the hospital’s invoicing system. Financial loss and savings of cancellations were calculated from the total cost of procedures. As a result the total cost of DOS cancellations during the nine-month time period was 953,374.27 euros and mean loss of a single cancelled operation was 2,459.91 euros. The total of material savings for the hospital were 106,917.33 euros. As a conclusion, DOS cancellations cause unnecessary wastage, and financial aspects should be followed and evaluated systematically by setting goals and providing continuing developments.

e18524 Background: Pembrolizumab has been approved by the FDA for the treatment of recurrent and refractory squamous cell cancer of the Head and Neck. This approval was based on the favorable results noted in the pembrolizumab arm of the KEYNOTE-040 clinical trial which compared pembrolizumab with the standard of care (methotrexate/cetuximab/docetaxel). This study aims to compare the financial aspects of these treatment arms in the setting of their relative clinical advantages in terms of increased overall survival by applying current pricing of the drugs and treatment for side effects. Methods: Data published from the KEYNOTE-040 study was used to generate a model incorporating the cost of each drug in both arms. The incidence of side effects was also extracted from the published data. The cost of treatment of side effects was extracted from previously published data and used for cost estimation in the model. The number of years added in terms of overall survival was calculated for the entire experimental arm and the cost of each such year was calculated. This model assumes that all drugs were supplied at the cost indicated at the retail price advertised by their producers. The cost was adjusted for inflation to the current year. Results: Based on current pricing, 248 patients in the control arm which involved methotrexate /cetuximab /docetaxel incurred an estimated total cost of $2,918,185 over 24 months. The total cost for the pembrolizumab arm based on current pricing was $36,744,819 for 247 patients over 24 months. The cost of management of adverse effects was $383,910 vs. $18,728 (Std. of care vs. Pembrolizumab). The total cost averaged over all patients in both arms was $13,314 vs. $ 148,840. There is an inverse relationship between drug cost and management of adverse side effects in both arms. Conclusions: Treatment with pembrolizumab confers an increase in overall survival but the cost of the incremental gain appears to be high. The model makes several assumptions including the distribution of cost over the patient population in both arms and extrapolates it to the cost in US dollars. It is very likely that the quality of life was superior in the pembrolizumab arm but it was not incorporated into our model. Justification of the continued use of pembrolizumab must be weighed against the long term survival benefits accrued by its usage in the context of a different and possibly better quality of life.

On the basis of balancing rations of cows taking into account daily yields, additives, quality of volume feed, as well as the cost of rations, the economic efficiency of the complex of feed additives is deter-mined. The observations were carried out in farm in the Tver region, the Agrofirm Dmitrova Gora JSC. The branch, where the research was carried out, includes several sites for milk production and cultivation of young cattle. From lactating cows Holstein breed expect to receive the maximum amount of dairy products, both for lactation, and for the entire life of use. But the expectation should be active, the animal should be properly prepared for the physiologically stressful period of milk formation. Based on the re-sults, it can be stated that the volume feed in the farm, which breeds highly productive Holstein cattle, should be the 1 and 2 class. The additional cost of a complete balance of the diet while increasing the dai-ly yield from 17 kg to 39 kg using a set of feed additives pays off, reducing the total cost of feed in the calculation by 1 kg of milk received and increasing feed payment by 88.1%.
