The resource potential, "fractured" reservoir, reservoir type and stimulation technology of Jurassic tight oil in central Sichuan basin were investigated. Based on the evaluation method resource, amount resources five layers estimated at 1.6 billion tons, showing that potential Basin is huge. Integrated analysis static dynamic data including core-description, thin section examination, well test exploration show reservoirs are fracture-pore with ultra-low porosity, super-low permeability,...
In this paper, a connectedness in stratified L-generalized convergence spaces, is defined and discussed. This different from Jäger's connectedness, particular, it for L-subsets however crisp subsets. Thus give partly answer to question 2016: define lattice-valued spaces. Then the basic properties of are
Taking the B bed of second submember member Triassic Jialingjiang Formation in Moxi gas field as an example, basic characteristics and controlling factors “Khali” powder dolomite reservoir is analyzed systematically, genesis forming mechanism crystal are examined. Logging core analysis show that has intercrystalline pores dissolved main storage space, mainly lamellar throats, good configuration between medium porosity low permeability, representing typical porous-type reservoir....
In this paper, we consider the parallel-machine scheduling with step-deteriorating jobs. The actual processing time of each job deteriorates as a step function if its starting is beyond given deteriorating date. We focus on case common For minimization problem total completion time, first show that NP-hard in strong sense. Then propose one property any optimal schedule. Furthermore, prove two special cases normal or penalty are polynomially solvable. weighted analyze NP-hardness and present...
We consider the problems of scheduling deteriorating jobs with release dates on a single machine (parallel machines) and can be rejected by paying penalties. The processing time job is simple linear increasing function its starting time. For model, objective to minimize maximum lateness accepted plus total penalty jobs. show that problem NP-hard in strong sense presents fully polynomial approximation scheme solve it when all have agreeable due dates. parallel-machine delivery completion When...
High-spin states of $^{94}\mathrm{Nb}$ have been studied by in-beam $\ensuremath{\gamma}$-ray spectroscopic methods using the $^{82}\mathrm{Se}(^{18}\mathrm{O},p5n)^{94}\mathrm{Nb}$ reaction at beam energies 82 and 88 MeV. Particle-$\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}$ coincidence measurements CsI high-purity germanium arrays are employed to gain selectivity Nb isotopic products. The level scheme has extended up excitation energy...
We consider the unbounded parallel batch scheduling with deterioration, release dates, and rejection. Each job is either accepted processed on a single batching machine, or rejected by paying penalties. The processing time of simple linear increasing function its starting time. objective to minimize sum makespan jobs total penalty jobs. First, we show that problem NP-hard in ordinary sense. Then, present two pseudopolynomial algorithms fully polynomial-time approximation scheme solve this...

We consider several single machine scheduling problems in which the processing time of a job is simple linear increasing function its starting and each has delivery time. The objectives are to minimize functions about completion times. For former three problems, we propose polynomial-time algorithms solve them. last problem, prove that it NP-hard when all jobs have release dates.
Many practical problems emphasize the importance of not only knowing whether an element is selected but also deciding to what extent it selected, which imposes a challenge on submodule optimization. In this study, we consider monotone, nondecreasing, and non-submodular maximization integer lattice with cardinality constraint. We first design two-pass streaming algorithm by refining estimation interval optimal value. For each element, decides save gives number reservations. Then, introduce...
Biochar application to soils is currently considered as a means of mitigating climate change by sequestering C, which withdraws CO2 from the atmosphere and consequently influences trend global change. However, only few studies have been done on surface albedo variations farmland, it might be true that biochar soil could induce radiative forcing changing albedo. Based this background, study aiming at characterization seasonal changes in farmland both with plants without plants, its effect...
We consider parallel identical machines scheduling problems with deteriorating maintenance activities and the option of job rejection. Each machine has at most one activity. The length each activity increases linearly its starting time. location on needs to be determined. goal is find sequence jobs minimize cost; we further model by allowing A either accepted processed machines, or rejected. determine cost plus total rejection penalty rejected jobs. When makespan, design a pseudo-polynomial...

This paper mainly discusses machine scheduling problems with job rejection and DeJong's learning effect. The goal is to determine the sequence of accepted jobs so as minimize cost plus total penalty rejected jobs. costs are makespan completion time. For single-machine setting, we show that both objectives can be optimally solved in polynomial parallel-machine minimizing time still polynomially solvable, whereas other problem $ NP $-hard, for which provide a fully polynomial-time...
