Abstract:

N-queen problem represents a class of constraint problems. It belongs to set of NP-Hard problems. It is applicable in many areas of science and engineering. In this paper N-queen problem is solved using genetic algorithm. A new genetic algoerithm is proposed which uses greedy mutation operator. This new mutation operator solves the N-queen problem very quickly. The proposed algorithm is applied on some instances of N-queen problem and results outperforms the previous findings

Abstract:

This study investigated the reliability of measuring the median nerve cross-sectional area (CSA) at the carpal tunnel inlet using a handheld ultrasound device (HUD) compared to a standard ultrasound system, focusing on intra- and inter-operator reproducibility among novice and expert operators. Employing a prospective cross-sectional design, 37 asymptomatic adults were assessed using both devices, with measurements taken by an expert with over five years of experience and a novice with less than six months. The CSA was determined using manual tracing and ellipse methods, with reproducibility e

Abstract:

The representation of mathematical models via piecewise differential and integral operators for dynamic systems has this potential to capture cross-over behaviors such as a passage from deterministic to randomness which can be exhibited by different systems. A 3D mathematical model, similar to the prey-predator system, of tumor-immune interaction with piecewise differential and integral operators is developed and analyzed. Three different scenarios, namely, cross-overs from deterministic to randomness, the Mittag-Leffler law to randomness, and a cross-over behavior from fading memory to the po

Abstract:

Highlights Stress was measured in harvest operators who performed on-the-go unloading manually and with an automated system. Automated unloading reduced the average grain cart and combine operator stress rate by 18% and 12%, respectively, compared to manual operation. Harvest operators usually worked more than 9 hours and often worked more than 12 hours per workday during harvest. The use of automated unloading systems could positively affect the health of harvest operators. Abstract. On-the-go unloading improves harvest operational efficiency, but it requires skilled labor because it is chall

Abstract:

SUMMARY Structural joint inversion of several data sets on an irregular mesh requires appropriate coupling operators. To date, joint inversion algorithms are primarily designed for the use on regular rectilinear grids and impose structural similarity in the direct neighbourhood of a cell only. We introduce a novel scheme for calculating cross-gradient operators based on a correlation model that allows to define the operator size by imposing physical length scales. We demonstrate that the proposed cross-gradient operators are largely decoupled from the discretization of the modelling domain, wh

Abstract:

Entanglement is the key resource for quantum technologies and is at the root of exciting many-body phenomena. However, quantifying the entanglement between two parts of a real-world quantum system is challenging when it interacts with its environment, as the latter mixes cross-boundary classical with quantum correlations. Here, we efficiently quantify quantum correlations in such realistic open systems using the operator space entanglement spectrum of a mixed state. If the system possesses a fixed charge, we show that a subset of the spectral values encode coherence between different cross-bou

As in conventional error matrix-based accuracy assessments, collocated reference sample data are often used for characterizing per-pixel (local) accuracies in land-cover change maps so that local accuracy predictions can be made using direct methods. In that way, correctness in “from-to” change categorization at sample pixels is assessed and modeled directly. To circumvent the issue of reference sample data being non-collocated, as is often the case for sample data collected independently for mono-temporal reference land-cover labeling or those added necessarily to reflect landscape changes, t

OperationSteinbock, or as it became known, the ‘Baby Blitz’ was the Luftwaffe’s last sustained night bomber offensive against the United Kingdom. In this book, renowned Luftwaffe historian Chris Goss explains how and why the Luftwaffe's last cross-Channel campaign was such a contrast to the Battle of Britain and subsequent Blitz of 1940–41. In 1944, the Luftwaffe’s under-trained, hard-pressed, and inexperienced bomber crews were out-thought

The four basic operators cross over into the four classes of figures and engender the most basic list of possible and necessary figures. This analysis of figurative speech is the springboard into literary rhetoric. Four basic figures are sufficient to derive all others, superseding the impasse created by all past treatises

This chapter examines the hybrid origins of Hong Kong's Huangmei opera film.

Under colonial suppression of local nationalist objectives, the resulting hybridized genre carried a vital female imaginary in nostalgic Chinese wrappings. In contrast to Indi

Distributions of thermo-fluid information, including surface distributions, cross section distributions and projected distributions are common forms of data for internal cooling research. For over half a century since 2-D thermo-fluid data were obtainable, there were very few universal tools to regress images. While several mathematical methods worked well with regressing zero-dimensional data, they were hardly compatible with 2-D data. Recent progress in the deep learning domain provided capability f

Abstract A major Deepwater operator in the Gulf of Mexico needed to set a 330 ft cross sectional cement barrier in 13 5/8" × 20" casing. This well in over 6, 000 ft+ MD water depth required a cement barrier placed just above the 20" casing shoe in order to meet the qualifications to plug and abandon the well. The 13 5/8" Perf/Wash/Cement system was the best solution to circulate/place cement in a controlled and focused area. The 330 ft long section was planned to be washed and cemented in one run and verified by pressure testing and tagging top of cement. Careful study of Cement Bond Logs and

Abstract:

Finite element (FE) computational human body models (HBMs) have gained popularity over the past several decades as human surrogates for use in blunt injury research. FE HBMs are critical for the analysis of local injury mechanisms. These metrics are challenging to measure experimentally and demonstrate an important advantage of HBMs. The objective of this study is to evaluate the injury risk predictive power of localized metrics to predict the risk of pelvic fracture in a FE HBM. The Global Human Body Models Consortium (GHBMC) 50th percentile detailed male model (v4.3) was used for this study.

Abstract:

Evaluating deep multiagent reinforcement learning (MARL) algorithms is complicated by stochasticity in training and sensitivity of agent performance to the behavior of other agents. We propose a meta-game evaluation framework for deep MARL, by framing each MARL algorithm as a meta-strategy, and repeatedly sampling normal-form empirical games over combinations of meta-strategies resulting from different random seeds. Each empirical game captures both self-play and cross-play factors across seeds. These empirical games provide the basis for constructing a sampling distribution, using bootstrappi

Abstract:

The Indonesian government plans to sue PTTEP Australasia, PTTEP, and PTT for the 2009 Montara oil spill, seeking 27.4 trillion rupiahs (USD 1.85 billion) in damages. The explosion on an oil rig in the Montara field, operated by PTTEP AA, caused one of Australia's worst oil disasters, spilling 23.5 million liters of oil into the Timor Sea for 74 days and impacting the Indonesian coast. The government initially filed a lawsuit but withdrew it to strengthen their claim and correct the defendants' names. Despite a settlement with Indonesian farmers, the government seeks additional compensation for

Abstract:

The efficiency of separation operations is a critical point to determinate the yield and economic viability of a production process. Because of this, the selection of adequate operation parameters has become an important part in the design of a new bioprocess. [1, 2]. Due to its low cost and easily transformation to industrial scale, the cross-flow filtration had been highly studied in terms of process performances of microorganism biomass separation without being concerned about their viability. In this work, two parameters of cross-flow filtration were evaluated to separate yeast cells from

Abstract:

The rapid growth in population and related demand for travel during the past few decades has had a catalytic effect on traffic congestion, air quality, and safety in many urban areas. Transportation managers and planners have planned for new facilities to cater to the needs of users of alternative modes of transportation (e.g., public transportation, walking, and bicycling) over the next decade. However, there are no widely accepted methods, nor there is enough evidence to justify whether such plans are instrumental in improving mobility of the transportation system.

Abstract:

Over the past several years, improvements in clamp-on ultrasonic meter technology have caused increased interest in applying this technology within the natural gas industry. Clamp-on ultrasonic meters (CUSMs), which are mounted on the outside of a pipe, send and receive ultrasonic waveforms through the pipe wall. This configuration offers several potential advantages over in-line meters, including portability and the ability to be installed without shutdown and disassembly of the pipeline. CUSMs, like their in-line counterparts, use sophisticated electronics to control the meter operation and
