Software development is getting a transition from centralized version control systems(CVCSs)like Subversion to decentralized version control systems(DVCDs)like git due to lesser efficiency of former in terms of branching,fusion,time,space,merging,offline commits&builds and repository,etc.git is having a share of 77%of total VCS,followed by Subversion with a share of 13.5%.The majority of software industries are getting a migration from Subversion to git.Only a few migration tools are available in the software industry.Still,these too lack in many features like lack of identifying the empty directories as premigration check,failover capabilities during migration due to network failure or disk space issue,and detailed report generation as post-migration steps.In this work,a holistic,proactive and novel approach has been presented for pre/during/post-migration validation from Subversion to git.Many scripts have been developed and executed run-time over various projects for overcoming the limitations of existing migration software tools for a Subversion to git migration.During premigration,none of the available migration tools has the capability to fetch empty directories of Subversion,which results in an incomplete migration from Subversion to git.Many Scripts have been developed and executed for pre-migration validation and migration preparation,which overcomes the problem of incomplete migration.Experimentation was conducted in SRLC Software Research Lab,Chicago,USA.During the migration process,in case of loss of network connection or due to any other reason,if migration stops or breaks,available migration tools do not have capabilities to start over from the same point where it left.Various Scripts have been developed and executed to keep the migration revision history in the cache(elastic cache)to start from the same point where it was left due to connection failure.During post-migration,none of the available version control migration tools generate a detailed report giving information about the total size of so

The Longmenshan fault is a thrust fault which runs along the base of the Longmen Mountains in Sichuan province,southwestern China.The southern segment of the fault had two distinct responses to the Ms 8 Wenchuan and Ms 7 Lushan earthquakes.This study determines characteristics of the structural geology of the Longmenshan fault to evaluate how it influenced the two aforementioned earthquakes.This research was done within a Geoinformation Technologies(Gi T) environment based on multi-source remote sensing and crustal movement data extracted from the Global Positioning System(GPS).The spatial distribution of the southern segment of the Longmenshan fault zone was comprehensively analyzed to study both earthquakes.The study revealed that the Wenchuanand Lushan earthquakes occurred on two relatively independent faults.In addition,there was a nearly constant-velocity crustal movement zone between the two epicenters that probably had a compressive stress with slow motion.Furthermore,the central fault and a mountain back fault gradually merged from north to south.The Lushan earthquake was not an aftershock of the Wenchuan earthquake.The research showed that fault zones within 30–50 km of State Highway 318 are intensive and complex.In addition,crustal movement velocity decreased rapidly,with a strong multi-directional shear zone.Thus,activity in that zone was likely stronger than in the northern part over the medium to long term.

Let S be a complete intersection of a smooth quadric 3-fold Q and a hypersurface of degree d in P4.We analyze git stability of S with respect to the natural G=SO(5,C)-action.We prove that if d 4 and S has at worst semi-log canonical singularities then S is G-stable.Also,we prove that if d 3 and S has at worst semi-log canonical singularities then S is G-semistable.

In this paper,the authors study the moduli space of quasi-polarized complex K3 surfaces of degree 6 and 8 via geometric invariant theory.The general members in such moduli spaces are complete intersections in projective spaces and they have natural git constructions for the corresponding moduli spaces and they show that the K3 surfaces with at worst ADE singularities are git stable.They give a concrete description of boundary of the compactification of the degree 6 case via the Hilbert-Mumford criterion.They compute the Picard group via Noether-Lefschetz theory and discuss the connection to the Looijenga’s compactifications from arithmetic perspective.One of the main ingredients is the study of the projective models of K3 surfaces in terms of Noether-Lefschetz divisors.

Microencapsulation is a technique which improves the survival and viability of probiotics. We demonstrate encapsulation of five potential probiotic yeasts with alginate and gum as encapsulation matrices to improve their gastrointestinal transit. Gum extracted from various cereals viz. rice, oats, barley, finger millet and pearl millet along with alginate have been used to encapsulate five potential probiotic yeasts. Screening was carried out by measuring swelling index, encapsulation efficiency and nutritional value of microcapsules encapsulated with alginate and gum. The concentration of OBG, sodium alginate and inoculum dosage of probiotic yeasts was optimized using response surface methodology (RSM). Efficiency of alginate OBG microcapsules with or without coating materials viz. whey protein and chitosan also tested. The mucoadhesion ability and storage stability of alginate OBG microcapsules with coating materials were tested. Highest encapsulation efficiency of probiotic yeasts was noted using oats bran gum (OBG) microcapsules along with alginate in all the five probiotic yeasts. Notably whey protein coated microcapsules showed maximum git tolerance (95%) and mucoadhesion (90%) for L. starkeyi VIT-MN03. The minimum loss of viability was observed in L. starkeyi VITMN03 microcapsules on 60th day of storage. This is the first report on optimization and survival of microencapsulated probiotic yeasts under simulated git conditions using natural gum and alginate as encapsulation matrices and whey protein as coating material.

企业在开发软件的过程中,都会使用版本控制工具来追踪文件的变更和协同团队进行并行开发。以前一般使用集中式版本控制工具,例如SVN和CVS等工具。分布式版本控制工具git出现后因为其具有分布式去中心化和分支管理、代码合并等强大功能,立即风靡全球。同样git也可以用于编程语言教学。在教学中,git可以减轻教师的负担,提高教师的工作效率;促进学生的学习,形成学习共同体。也为学生将来在工作中适应企业需求奠定基础。
