Measurement and Spatial Distribution of Urban Land Use Compactness in Chaoyang District of Beijing, China

China is in the process of rapid urbanization, and wise land use is critical to the long-term sustainbility of Chinese cities. Promotion of a compact city is typically believed to be a helpful for sustainable land use management. However, given the fact that Chinese cities are characterized by high population densities, the applicability of a more compact solution to expanding cities in China remains questionable; there is little evidence to suppot the many claims in its favor. In seeking to provide empirical data to explore the application of compact city theory in China, one of the key problems researchers face is the task of measuring the urban compactness, in order to objectively investigate the current characteristics of urban compactness. To meet this need, indices were developed for measuring the urban land use compactness, by which the partial distribution characteristics of urban land use compactness were identified and applied to the Chaoyang district of Beijing. The following conclusion can be made: (1) Comprehensive land use compactness in Chaoyang district has increased during the period 2001-2007, especially the population density; (2) the spatial distribution of land use compactness has the characteristics of a ring structure, which shows a decreasing trend with its distance to the city center; (3) there is a strong positive correlation between urban land use compactness and location. The better the location is, the higher the land use compactness is

The Parametric Generalized Fractional Nikiforov-Uvarov Method and Its Applications

By using generalized fractional derivative, the parametric generalized fractional Nikiforov-Uvarov (NU) method is introduced. The second-order parametric generalized differential equation is exactly solved in the fractional form. The obtained results are applied on the extended Cornell potential, the pesudoharmonic potential, the Mie potential, the Kratzer-Fues potential, the harmonic oscillator potential, the Morse potential, the Woods-Saxon potential, the Hulthen potential, the deformed Rosen-Morse potential and the Poschl-Teller potential which play an important role in the fields of molecular and hadron physics. The special classical cases are obtained from the fractional cases at ELFA = BETA =1 which are agreements with recent works.Comment: 15 page

Properties and Behaviors of Heavy Quarkonia: Insights Through Fractional Model and Topological Defects

In this study, we investigated the impact of a topological defect on the properties of heavy quarkonia using the extended Cornell potential. We solved the fractional radial Schrodinger equation (SE) using the extended Nikorov-Uvarov (ENU) method to obtain the eigen energy, which allowed us to calculate the masses of charmonium and bottomonium. One significant observation was the splitting between np and nd states, which we attributed to the presence of the topological defect. We discovered that the excited states were divided into components corresponding to 2l + 1, indicating that the gravity field induced by the topological defect interacts with energy levels in a manner similar to the Zeeman effect caused by a magnetic field. Additionally, we derived the wave function and calculated the root mean radii for charmonium and bottomonium. A comparison with classical models was performed, resulting in better results being obtained. Furthermore, we investigated the thermodynamic properties of charmonium and bottomonium, determining quantities such as energy, partition function, free energy, mean energy, and specific heat for p-states. The obtained results were found to be consistent with experimental data and previous works. In conclusion, the fractional model used in this work proved essential in understanding the various properties and behaviors of heavy quarkonia in the presence of topological defects.Comment: 29 pages, 13 figures, 6 Table

Perancangan Sistem Informasi Akademik pada TK Dalilussa'adah Berbasis Web

Utilization of informatics technology in business especially in education field can reduce the potential mistake of data processing compared to manual data processing. This study aims to build information system of academic at kindergarden Dalilussa'adah Karawang. The advantage is to provide convenience in processing the value of report cards and teaching scheduling. This application is implemented with, PHP programming language, MySQL database as data storage media. Test method using black box testing with structured approach. Approach to the development of systems equipped with flow map tools, context diagrams, DFD, data dictionary, ERD, table relationships and waterfall methods that create the initial form of the system to be created and continuously tested and developed. Information system of academic at kindergarden Dalilussa'adah Karawang are still done manually, so these can cause data errors caused by human error factor. This web-based application is designed online so teachers and homers can see the teaching schedule and input student grades. The results of scheduling teaching and processing of student report cards can be viewed and processed as reports in the form of useful information for homeroom teachers and students. The results of this study are expected to answer the difficulties that are often faced by the teaching, curriculum, teachers and homeroom so that it can be much more efficient and effective. This application is also expected to be a reference for other researchers and then can develop it for further research

ASEAN Non-Intervention Principles: An Alternative Settlement towards Human Rights Violation in Rohingya

The frame of international news is colored with a series of systemic and consistent human rights violation experienced by the Rohingya ethnic group in Burma. Toward this case, it is unlikely for Burma to be willing and to be able to resolve this case internally. Hence, as a regional security and stability guard in the Southeast Asia region, ASEAN should take part in settling human rights violations that occur in its member states. However, every settlement attempted by ASEAN is constantly distracted with Non-Intervention Principles. This research aims to examine the alternative ideas for Non-Intervention Principles of ASEAN as a settlement towards human rights violation on Rohingya ethnic. This research used normative research, based on the secondary data was employed as the research method. The obtained data were analyzed by using qualitative analysis. The research found that the Non-Intervention principle has been applied in ASEAN in the most rigid form. Meanwhile, Humanitarian Assistance and Humanitarian Intervention mechanism is an alternative settlement towards human rights violations on the Rohingya ethnic group in Myanma

Graphene zigzag ribbons, square lattice models and quantum spin chains

We present an extended study of finite-width zigzag graphene ribbons (ZGRs) based on a tight-binding model with hard-wall boundary conditions. We provide an exact analytic solution that clarifies the origin of the predicted width dependence on the conductance through junctions of ribbons with different widths. An analysis of the obtained solutions suggests a new description of ZGRs in terms of coupled chains. We pursue these ideas further by introducing a mapping between the ZGR model and the Hamiltonian for N-coupled quantum chains as described in terms of 2N Majorana fermions. The proposed mapping preserves the dependence of ribbon properties on its width thus rendering metallic ribbons for N odd and zero-gap semiconductor ribbons for N even. Furthermore, it reveals a close connection between the low-energy properties of the ZGR model and a continuous family of square lattice model Hamiltonians with similar width-dependent properties that includes the $\pi-$flux and the trivial square lattice models. As a further extension, we show that this new description makes it possible to identify various aspects of the physics of graphene ribbons with those predicted by models of quantum spin chains (QSCs)
