Livestock is a critical socioeconomic asset in developing countries such as Ethiopia, where the economy is significantly based on agriculture and animal husbandry. However, there is an enormous loss of livestock population, which undermines efforts to achieve food security and poverty reduction in the country. The primary reason for this challenge is the lack of a reliable and prompt diagnosis system that identifies livestock diseases in a timely manner. To address some of these issues, the integration of an expert system with deep learning image processing was proposed in this study. Due to the economic significance of cattle in Ethiopia, this study was only focused on cattle disease diagnosis. The cattle disease symptoms that were visible to the naked eye were collected by a cell phone camera. Symptoms that were identified by palpation were collected by text dialogue. The identification of the symptoms category was performed by the image analysis component using a convolutional neural network (CNN) algorithm. The algorithm classified the input symptoms with 95% accuracy. The final diagnosis conclusion was drawn by the reasoner component of the expert system by integrating image classification results, location, and text information obtained from the users. We developed a prototype system that incorporates the image classification algorithms and the reasoner component. The evaluation result of the developed system showed that the new diagnosis system could provide a rapid and effective diagnosis of cattle diseases.

On the uncertainty of interwell connectivity estimations from the capacitance-resistance model

引用

Petroleum Science 2014年第2期11卷 265-271页

The capacitance-resistance model （CRM） is an alternative to conventional reservoir simulation. CRM, a simplification of complex numerical models, uses production and injection rates to infer a reservoir description. There is no prior geologic model. The principal output of CRM fitting is the fraction of injected fluid （usually water） that is produced at a producer at steady-state. These fractions are interwell connectivities. Interwell connectivities are fundamental information needed to manage waterfloods in oil reservoirs. The data-driven CRM is a fast tool to estimate these parameters in mature fields and allows one to make full use of the dynamic data available. This paper considers the problem of setting an upper bound on the uncertainty of interwell connectivities for linear-constrained models. Using analytical bounds and numerical simulations, we derive a consistent upper limit on the uncertainty of interwell connections that can be used to quantify the information content of a given dataset.

Input signal design to estimate interwell connectivities in mature fields from the capacitance-resistance model

Interwell connectivities are fundamental parameters required to manage waterfloods in oil reservoirs. Data-driven models, such as the capacitance-resistance model （CRM）, are fast tools to estimate these parameters from time-correlations of input （injection rates） and output （production rates） signals. Noise and structure of the input time-series impose limits on the information that can be extracted from a given data-set. This work uses the CRM to study general prescriptions for the design of input signals that enhance the information content of injection/production data in the estimation of well-to-well interactions. Numerical schemes and general features of the optimal input signal strategy are derived for this problem.

The Qinghai-Tibet plateau is one of major saline lake regions in China, where saline lakes are widespread and constitute an important object of researches on the palaeoclimatic change in the region. On the basis of comprehensive investigations of the evolution of the lake's surface and sediments on the plateau, the authors have further demonstrated the existence of a pan-lake stage (river and lake flooding stage) on the Qinghai-Tibet plateau during the period of about 40+-28 ka B.P. and analyzed the palaeoclimatic characteristics of the pan-lake period and relationships between the ancient monsoons and the uplift of the plateau since the beginning of the Quaternary.

Circumcision reduces prostate cancer risk

作者： Brian J Morris lake H Waskett School of Medical Sciences University of SydneySydney NSW 2006 Australia CircumcisionIndependent Reference and Commentary Service Manchester M26 1JR UK

There is a strong negative correlation between prostate cancer and circumcision rate across 181 countries （P〈0.0001）. Adding to the large protective effect of cir- cumcision seen in small studies over the past six decades, a recent large study in Seattle has shown a smaller protective effect. If verified by other large studies else- where, the finding would add to the wide array of benefits conferred by this safe, sim- ple procedure that is best performed in infancy.

Journal of Environmental & Earth Sciences 2020年第2期2卷 19-25页

作者： Mulu Fikeraddis lake Endeshaw Department of Physics Worabe UniversityWorabeEthiopia

In this paper we access the effects of two atmospheric variables (temperatureand relative humidity) on two important pollutants in the atmosphere(Nitrogen oxides (NOx) and carbon monoxide (CO)) by using one year(2016) data of Addis Ababa. Temperature has impact on atmosphericmixing and cause for the reduction of NOx as temperature *** are positive correlation between temperature and CO concentrationfrom January to April with (R^2 = 0.69), negative correlation from Mayto August with (R2 = 0.92) and no correlation for the remaining *** and CO have moderate positive and negative correlation with relativehumidity during the months January-April (R^2 = 0.294 for NOx and R^2 =0291 for CO) and in the months May-August are R2 = 0.97 and R2 = 0.15for NOx and CO respectively. But there are no clear correlation betweenthe NOx and CO with relative humidity from *** concentrations during wet season was almost about twice that of thedry season, but no such difference was observed in the case of CO. Theseasonal average air temperature in wet season is relatively lower than dryseason. NOx exhibited positive and CO negative seasonal correlations withrelative humidity.

Representations of coherent and squeezed states in an extended two-parameter Fock space

引用

Chinese Physics C 2012年第8期36卷 703-709页

Recently an f -deformed Fock space which is spanned by ｜ n λ was introduced. These bases are the eigenstates of a deformed non-Hermitian Hamiltonian. In this contribution, we will use rather new nonorthogonal basis vectors for the construction of coherent and squeezed states, which in special case lead to the earlier known states. For this purpose, we first generalize the previously introduced Fock space spanned by ｜ n λ bases, to a new one, spanned by extended two-parameters bases ｜ n λ 1 ,λ 2 . These bases are now the eigenstates of a non-Hermitian Hamiltonian H λ 1 ,λ 2 = a λ 1 ,λ 2 a ＋ 1 2 , where a λ 1 ,λ 2 = a ＋ λ 1 a ＋ λ 2 and a are, respectively, the deformed creation and ordinary bosonic annihilation operators. The bases ｜ n λ 1 ,λ 2 are nonorthogonal （squeezed states）, but normalizable. Then, we deduce the new representations of coherent and squeezed states in our two-parameter Fock space. Finally, we discuss the quantum statistical properties, as well as the non-classical properties of the obtained states numerically.
