Advances in Mathematical Physics , 2013, DOI: 10.1155/2013/893254
Abstract: By using the Hille-Yosida theorem, Phillips theorem, and Fattorini theorem in functional analysis we prove that the /G/1 queueing model with vacation times has a unique nonnegative time-dependent solution. 1. Introduction The queueing system when the server become idle is not new. Miller [1] was the first to study such a model, where the server is unavailable during some random length of time for the M/G/1 queueing system. The M/G/1 queueing models of similar nature have also been reported by a number of authors, since Levy and Yechiali [2] included several types of generalizations of the classical M/G/1 queueing system. These generalizations are useful in model building in many real life situations such as digital communication, computer network, and production/inventory system [3–5]. At present, however, most studies are devoted to batch arrival queues with vacation because of its interdisciplinary character. Considerable efforts have been devoted to study these models by Baba [6], Lee and Srinivasan [7], Lee et al. [8, 9], Borthakur and Choudhury [10], and Choudhury [11, 12] among others. However, the recent progress of /G/1 type queueing models of this nature has been served by Chae and Lee [13] and Medhi [14]. In 2002, Choudhury [15] studied the /G/1 queueing model with vacation times. By using the supplementary variable technique [16] he established the corresponding queueing model and obtained the queue size distribution at a stationary (random) as well as a departure point of time under multiple vacation policy based on the following hypothesis. “The time-dependent solution of the model converges to a nonzero steady-state solution.” By reading the paper we find that the previous hypothesis, in fact, implies the following two hypothesis. Hypothesis 1. The model has a nonnegative time-dependent solution. Hypothesis 2. The time-dependent solution of the model converges to a nonzero steady-state solution. In this paper we investigate Hypothesis 1. By using the Hille-Yosida theorem, Phillips theorem, and Fattorini theorem we prove that the model has a unique nonnegative time-dependent solution, and therefore we obtain Hypothesis 1. According to Choudhury [15], the /G/1 queueing system with vacation times can be described by the following system of equations: where ; represents the probability that there is no customer in the system and the server is idle at time ; represents the probability that at time there are customers in the system and the server is on a vacation with elapsed vacation time of the server lying in . represents the probability that

Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.611185
Abstract: We investigate an N-unit series system with finite number of vacations. By analyzing the spectral distribution of the system operator and taking into account the irreducibility of the semigroup generated by the system operator we prove that the dynamic solution converges strongly to the steady state solution. Thus we obtain asymptotic stability of the dynamic solution of the system.

Abstract: A total of 62 green alga strains were isolated from the soils of Nanshan Mountain, Xinjiang. Used the blot method to characterize these metal resistance, the results indicated that XJU-3、XJU-28 and XJU-36 have resistance to 0. 1 mmol · L~(-1) Co~(2+) ;XJU-28 has resistance to 1 mmol·L~(-1) Zn~(2+) and Fe~(3+) , XJU-36 has resistance to 0. 05 mmol·L~(-1) Cu~(2+). Taxonomic evalua-tion of the three strains were investigated based on the morphology and the internal transcribed spacer (ITS) regions (including the 5. 8S). Based on morphological characteristics, the three strains were likely to Chlamydomonas. Phylogenetic reconstruction with the Neighbor-joining (NJ) method using sequences of ITS(including the 5. 8S) indicated that XJU-3 and XJU-28 are closed to Chlamydomonas zebra. XJU-36 is closed to Chlamydornonas petasua.
Formation of Binary Millisecond Pulsars by Accretion-Induced Collapse of White Dwarfs under Wind-Driven Evolution

Physics , 2014, DOI: 10.1088/0004-637X/800/2/98
Abstract: Accretion-induced collapse of massive white dwarfs (WDs) has been proposed to be an important channel to form binary millisecond pulsars (MSPs). Recent investigations on thermal timescale mass transfer in WD binaries demonstrate that the resultant MSPs are likely to have relatively wide orbit periods ($\gtrsim 10$ days). Here we calculate the evolution of WD binaries taking into account the excited wind from the companion star induced by X-ray irradiation of the accreting WD, which may drive rapid mass transfer even when the companion star is less massive than the WD. This scenario can naturally explain the formation of the strong-field neutron star in the low-mass X-ray binary 4U 1822$-$37. After AIC the mass transfer resumes when the companion star refills its Roche lobe, and the neutron star is recycled due to mass accretion. A large fraction of the binaries will evolve to become binary MSPs with a He WD companion, with the orbital periods distributed between $\gtrsim 0.1$ day and $\lesssim 30$ days, while some of them may follow the cataclysmic variable-like evolution towards very short orbits. If we instead assume that the newborn neutron star appears as an MSP and part of its rotational energy is used to ablate its companion star, the binaries may also evolve to be the redback-like systems.
The orbital period evolution of the supersoft X-ray source CAL 87

Physics , 2015, DOI: 10.1088/0004-637X/815/1/17
Abstract: CAL 87 is one of the best known supersoft X-ray sources. However, the measured masses, orbital period and orbital period evolution of CAL 87 cannot be addressed by the standard thermal-timescale mass-transfer model for supersoft X-ray sources. In this work we explore the orbital evolution of CAL 87 with both analytic and numerical methods. We demonstrate that the characteristics mentioned above can be naturally accounted for by the excited-wind-driven mass-transfer model.
Effective Spatial Data Partitioning for Scalable Query Processing

Computer Science , 2015,
Abstract: Recently, MapReduce based spatial query systems have emerged as a cost effective and scalable solution to large scale spatial data processing and analytics. MapReduce based systems achieve massive scalability by partitioning the data and running query tasks on those partitions in parallel. Therefore, effective data partitioning is critical for task parallelization, load balancing, and directly affects system performance. However, several pitfalls of spatial data partitioning make this task particularly challenging. First, data skew is very common in spatial applications. To achieve best query performance, data skew need to be reduced. Second, spatial partitioning approaches generate boundary objects that cross multiple partitions, and add extra query processing overhead. Consequently, boundary objects need to be minimized. Third, the high computational complexity of spatial partitioning algorithms combined with massive amounts of data require an efficient approach for partitioning to achieve overall fast query response. In this paper, we provide a systematic evaluation of multiple spatial partitioning methods with a set of different partitioning strategies, and study their implications on the performance of MapReduce based spatial queries. We also study sampling based partitioning methods and their impact on queries, and propose several MapReduce based high performance spatial partitioning methods. The main objective of our work is to provide a comprehensive guidance for optimal spatial data partitioning to support scalable and fast spatial data processing in massively parallel data processing frameworks such as MapReduce. The algorithms developed in this work are open source and can be easily integrated into different high performance spatial data processing systems.

Wind-Driven Evolution of White Dwarf Binaries to Type Ia Supernovae
Iminhaji Ablimit,Xiao-Jie Xu,Xiang-Dong Li
Physics , 2013, DOI: 10.1088/0004-637X/780/1/80
Abstract: In the single degenerate scenario for the progenitors of type Ia supernovae (SNe Ia), a white dwarf rapidly accretes hydrogen- or helium-rich material from its companion star, and appears as a supersoft X-ray source. This picture has been challenged by the properties of the supersoft X-ray sources with very low-mass companions and the observations of several nearby SNe Ia. It has been pointed out that, the X-ray radiation or the wind from the accreting white dwarf can excite wind or strip mass from the companion star, thus significantly influence the mass transfer processes. In this paper we perform detailed calculations of the wind-driven evolution of white dwarf binaries. We present the parameter space for the possible SN Ia progenitors, and for the surviving companions after the SNe. The results show that the ex-companion stars of SNe Ia have characteristics more compatible with the observations, compared to those in the traditional single degenerate scenario.
