A Lightweight Size Estimation Approach for Embedded System using COSMIC Functional Size Measurement

Functional Size Measurement (FSM) is an important component of a software project that provides information for estimating the effort required to develop the measured software. Although the embedded software is time-consuming to develop, COSMIC FSM can be estimated to get more accurate function size. The traditional Function Point methods are designed to measure only business application domain and are problematic in the real-time domain. As a result, COSMIC Functional Size Measurement (FSM) method is designed to measure both application domains. The design diagrams such as UML, SysML and the well-defined FSM procedure must use to accurately measure the functional size of embedded system. We have already developed the generation model based on SysML metamodel with an example of elevator control system. In this paper, we applied the generation model that is the classification of the instance level of object based on UML metamodel. After that, this paper also showed the mapping rules which mapped between the generation model and COSMIC FSM to estimate the functional size of embedded software with the case study of cooker system. This paper also proposed the light weight generation method of COSMIC FSM by using the generation model

Uniformly Integrated Database Approach for Heterogenous Databases

The demands of more storage, scalability, commodity of heterogenous data for storing, analyzing and retrieving data are rapidly increasing in today data-centric area such as cloud computing, big data analytics, etc. These demands cannot be solely handled by relational database system (RDBMS) due to its strict relational model for scalability and adaptability. Therefore, NoSQL (Not only SQL) database called non-relational database is recently introduced to extend RDBMS, and now it is widely used in some software developments. As a result, it becomes challenges regarding how to transform relational to non-relational database or how to integrate them to achieve business purposes regarding storage and adaptability. This paper therefore proposes an approach for uniformly integrated database to integrate data separately extracted from individual database schema from relational and NoSQL database systems. We firstly try to map the data elements in terms of their semantic meaning and structures with the help of ontological semantic mapping and metamodeling from the extracted data. We then cover structural, semantical and syntactical diversity of each database schema and produce integrated database results. To prove efficiency and usefulness of our proposed system, we test our developed system with popular datasets in BSON and traditional sql format using MongoDB and MySQL database. According to the results compared with other proficient contemporary approaches, we have achieved significant results in mapping similarity results although running time and retrieval time are competitive with the others

A Study on the system of Paintings and the Jātakas at Tilokaguru Cave in Sagaing

Myanmar culture has its origin in Bagan Period when Buddhism was first embraced. Buddhism has influenced on literature, languages, culture, tradition, art and architecture. This can be seen as a fact in the wall paintings in Tilokaguru Cave in Sagaing Hills. This paper aims at highlighting the influence of Buddhism on Myanmar architecture in Nyaungyan Period through a study on the wall paintings in Tilokaguru Cave. The wall paintings in the cave suggest that the Myanmar of Nyaungyan Period used Jātaka, Buddhavaṃsa Pāļ¹i and the Aṭhakatha (commentaries) in the wall paintings. They might not have only intended to decorate the walls, but also to give the viewers chances to develop wholesome mind. The knowledge of ancient Myanmar on Buddhist literature can also be seen in the paintings. It is noticeable that those ancient people used Buddhism widely both for religious and social purposes. This paper compares the wall paintings and Jātaka available in Tilokaguru Cave that was built in Nyaungyan Period with Buddhist literature. The studies will be helpful in observing the art of painting in Nyaungyan Period. Besides, they will give some information on the lifestyle of those people in Nyaungyan Period. Moreover, the lessons on social communication and behavior that can be learnt from those paintings are guidelines for the people of today to live their lives wholesomely. Most usefully, those paintings also depict the love of parents to their children, the nature of the wise and kind behavior of people in society

The title of the Aggamahapandita

Since the time of Buddha age, in the Buddha’s Sāsana, monks who were acted very sharply at the well-fare of the doctrine of the Buddha were offered “Etadagga Title”. Every age the kings usually offered the religious titles to the monks who were served sharply at the well-fare of Sāsana. In this paper, the beginning of Aggamahāpaṇḍita title and the qualification of it were describe

Green Aware Datacenter Selection

Datacenters have been the key systeminfrastructure for cloud computing. The demand fordatacenter computing has increased significantly inrecent years resulting in huge energy consumption.Renewable energy resources, such as wind and solarpower are rapidly becoming generation technologiesof significance in the United States and around theworld. The integration of renewable energy resourcesis usually very challenging because of theirintermittency and inter-temporal variations. The highenergy footprint of datacenters leads to seriousenvironmental issues. Energy expenditure has becomea significant fraction of datacenter operating costs.The proposed system is explicitly modeled theintermittent generation of renewable energy (WindPower Model and Solar Power Model) with respect tovarying weather conditions in the geographicallocation of each datacenter. Renewable energyresources datacenter selection framework is proposedto reduce the environmental impact and the systemtakes into account the benefit from the locationdiversity of different types of available renewableenergy resources and an efficient datacenter selection algorithm is proposed major concern of broader researchcommunity participating both from academia andindustry in the recent years.Large Internet companies (e.g. Google andMicrosoft) have significantly improved the energyefficiency of their multi-megawatt datacenters.However, the majority of the energy consumed bydatacenters is actually due to countless small andmedium-sized datacenters, which are much lessefficient. These facilities range from a few dozenservers housed in a machine room to several hundredsof servers housed in a large enterprise installation.These cost, infrastructure, and environmentalconcerns have prompted some datacenter operator togenerate their own solar/wind energy of draw powerdirectly from a nearby solar/wind farm. Green energysources promise to mitigate the issues surroundingnon-renewable generation, but their output is verysusceptible to environmental changes

A Study of Teachers’ Knowledge and Practices on Science Process Skills in Teaching Science

The primary purpose of this study was to investigate teachers’ knowledge and practices on science process skills in teaching science at the middle school level. The design adopted was a descriptive research design. Four townships were randomly selected from four districts in Yangon Region. Two high schools and two middle schools were selected by using a stratified random sampling technique. The population in this study consists of (640) Grade 5 students and (77) teachers who are teaching science. Three instruments: knowledge and practices questionnaires for junior science teachers and science achievement test were employed. Teachers’ knowledge and practices questionnaires involved (33) items. Science achievement test for students involved (18) items. One-Way ANOVA, dependent samples t-test and a correlation technique were used in this study. As a result of the research, there was a significant difference between experienced teachers and inexperienced teachers of knowledge and practices on science process skills. And, there was also a significant difference between basic and integrated science process skills of those teachers. Moreover, teachers who were well- trained got higher mean for knowledge and practices than teachers who were partially trained. Also, it was found that science teachers are familiar with basic science process skills. The research findings proved that teachers’ knowledge and students’ achievement were moderately related and teachers’ practices and students’ achievement were not correlated in all the selected schools. This indicated that if teachers’ knowledge on science process skills is high, they can arrange their teaching learning situation more systematically to teach their students more effectively

Calculation of Form Factor for 116Sn and 118Sn by Using Three-Parameter Gaussian Model Density Distribution

The purpose of research work is to calculate the Form factors of 116Sn and 118Sn nuclei by using three-parameter Gaussian model density distribution. The structural parameters, namely radius parameter (a), skin thickness parameter (z), charge density distribution parameter of 116Sn and 118Sn nuclei, taken from the experimental data are used to get the charge density distribution. After getting the charge density distribution, root mean square radius and the form factor are calculated. At the inner region (<4fm), the density distributions of 116Sn and 118Sn nuclei are slightly different. In the tail part, they are nearly the same for these nuclei. The calculated results of charge density distributions and root mean square radii are in good agreement with the experimental results. Moreover, the form factors of them also agree with the experimental values except 0.5fm-1 region

Analysis of a Single-Λ Hypernuclear Event in KEK-PS E373 Nuclear Emulsion Experiment

The purpose of this research is to identify a single-Λ hypernucleus and its decay products which support to get more information about hyperon-nucleon interaction. Before performing the analysis of a single-Λ hypernucleus, first, we have deduced the density of emulsion by calibrating the range-energy relation using alpha decay events data from thorium series. It is very important for the mass reconstruction of hypernucleus events in nuclear emulsion. And we have reconstructed a single-Λ hypernucleus event by using the kinematical reconstruction for mesonic and non-mesonic decay modes. From the result of our analysis, we can uniquely identify that single-Λ hypernucleus is B Λ 9 ${}_\Lambda ^9 B$ and decay products are 4He,3He, proton and neutron
