Development of Web Services: A Practical Approach for Libraries

Integrated library system is a part of institutional digital repository in modern library environment. Some popular open source software has been used in this regard. Development of an integrated institutional digital repository system is possible on the basis of global recommendations and local requirements of all libraries. OAI-PMH in Koha can be displayed in two ways such as sets and metadata with multilingual documents. The benefits of this study is harvest the records from the other library and it can make the union catalogue for anybody can be accessed from this integrated OAI-PMH harvesting framework available in Koha OPAC. This is the web 2.0 concept to achieve the multiple tasks of different library resources such as books, journals, magazines, reference books etc. for the better management and retrieval of resources among the library users. Digital resources are increasing in this modern age due to exponential growth of technological impact and its peripherals. IDRs will additionally include digital materials that subsist outside the physical and administrative bounds of any one digital library. IDRs will include all the processes and accommodations that are the backbone and nervous system of libraries. The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a very high performance mechanism for client server architecture in repository interoperability. Broadly it can be classified in two ways such as data provider and service provider. Data Provider can access the structured standards global metadata by using OAI-PMH tool. Development of web services through Koha can be achieved in four ways such as OAI-PMH, ILS-DI, Z39.50, and OPAC tag cloud. On the other hand service providers then easily harvest the metadata through a set of six verbs of OAI-PMH based URL. Requests for data can be based on a timestamp range, and can be restricted to named sets defined by the provider. Data providers can only manage the XML based Dublin Core metadata format. It is possible to design and develop an integrated institutional digital repository in different ways. In this research paper highlights and displays the important interface such as OAI-PMH, ILS-DI, Z39.50, and tag cloud and all the interfaces have been displayed in Koha OPAC. The whole tasks have been developed and performed in Ubuntu operating system for easy installation, configuration, and retrieving of library resources among the users.

Butterfly Family Detection and Identification using Convolutional Neural Network for Lepidopterology

Lepidopterology is a branch of entomology concerning the scientific study of moths and the three superfamilies of butterflies. The project aims to help biology students in identifying butterfly without harming the insect. In the studies of lepidopterology, the students normally need to capture the butterflies with nets and dissect the insect to identify its family types. Computer vision is a study on how computers can be used to make high-level comprehension from the input of digital image and videos. By utilizing the latest Image Processing technique, it can identify the correct species of butterfly with high accuracy by using layers of node in a Convolutional Neural Network (CNN). The work process starts with data acquisition (mining the butterfly image automatically from google image search), pre-processing (converting image format and rotation), analyzing and understanding digital images (group images into folders), and to make assumptions of the high complication data from the real world in the process of producing numerical information that can be comprehend by machines in order to form conclusions. Benefits of using CNN is to reduce the need for human and physical intervention in identifying each of the butterfly characters. This makes it easier to expand the database in the future. The image is acquired using Fatkun Batch Downloader to download large number of images. The project is develop using Tensorflow in Ubuntu operating system and interface is in HTML connected to the Python script via Flask. The results of the experiment show that CNN can identify with 92.7 percent of final accuracy with learning saturation (overfitting) of 500 cycle. While testing results shows 62.5 percent of accuracy in predicting new datasets.

Symbolic consumption and representation of self: a study of interactions in a virtual community of Ubuntu-Br users

Abstract This study aims to explain how the symbolic consumption of the Ubuntu operating system is used for the representation of self in interactions in the Ubuntu virtual community from Brazil. We adopted the Goffmanian concept of self, the netnography of communication as the research method, and case study as a research strategy. The paralinguistic, the extralinguistic, and the definition of “I” are aspects used in virtual interactions. They have the linguistic function of corroborating and praising the statements of migration of Windows users to Ubuntu, emphasizing the distinctive features of the concept of Ubuntu, highlighting its expression of shared feelings of love and freedom, as ways of projecting the self of humanity to each other. In the case of the operating system, this characteristic is represented through the provision of support among users at the forum of the virtual community.

Efficient Office Assistant Robot System: Autonomous Navigation and Controlling Based on ROS

This paper proposes a movable robot that can be used to deliver documents or small parcels (>2.0kg) between employees of an unstructured indoor office environment. The study reviews literature on robot navigation, apply promising techniques and test their accuracy in an unstructured indoor laboratory environment. There are many technologies available in robot navigation. We have selected free and open source software and inexpensive sensors and materials to build a low cost but accurate robot. Our system comprised of three units: first one that process sensor data, second one which is the navigating robot having sensors and actuators, and third one controlling part of office assistant robot system. We have used Robotic Operating System (ROS) indigo as the ground operating system in the background of Ubuntu Operating System. The experiment was conducted to examine the capabilities of the setup and studied its behavior, mapping and localization specifically according to the user commands. An unstructured indoor environment was selected with five users located on the sides. We considered both dark (55 lux – 60 lux) and bright (15 lux – 20 lux) illumination conditions in the room. Then, we allowed the robot to navigate autonomously according to the user commands between five users and monitored its accuracy by looking at the completion of the route to a target user. Results show that the robot has about 98.4% of accuracy of achieving the goal location on average in both lighting conditions and 98% and 98.8% of accuracies for bright and dark conditions respectively. Finally, this office assistant robot system could be practically used in an office environment in both bright and dark lighting conditions.

Modeling the conveyor-modular transfer of multimedia data in a sensor network of transport system

The paper studies the issues of distributed sensor networks interaction based on the Internet of Things architecture in the context of automated control systems design for dynamic objects of transport infrastructure. The properties of multimedia streams like digital telemetry exchange and packet data delivery between the sensor controllers of urban transport network are analyzed. A method of modifying the standard Ethernet network interface at the logical link control (LLC) sublayer on Raw Socket technology for joint transmission of multi-channel telemetry and packet data is proposed. A software simulator has been developed for conveyor-modular transfer in Python codes for Linux Ubuntu operating system based on the dynamic data structuring by the markup tags. The relevance of this work is due to the need to further improve the open system interoperability when building heterogeneous Internet of Things. As a result of the studies conducted, the use of conveyor-modular transfer (CMT) for telemetry data exchange with limited latency in urban control systems of transport safety is substantiated. The tests of the conveyor-modular simulator confirmed the relevance and logical consistency of the basic principles of encoding, transmitting and decoding multimedia data in the communication channel of the Internet of Things. The obtained results create scientific and methodological prerequisites for replenishing the existing TCP/IP stack with a new internetworking protocol with limiting delays, which can be used in conjunction with the IP protocol in real-time applications of the Internet of Things, and above all, in urban transport safety management systems

New hardware and software platform for experiments on a HUBER-5042 X-ray diffractometer with a DISPLEX DE-202 helium cryostat in the temperature range of 20–300 K

Huber-5042 diffractometer with a closed-cycle Displex DE-202 helium cryostat is a unique scientific instrument for carrying out X-ray diffraction experiments when studying the single crystal structure in the temperature range of 20–300 K. To make the service life longer and develop new experimental techniques, the diffractometer control is transferred to a new hardware and software platform. To this end, a modern computer; a new detector reader unit; and new control interfaces for stepper motors, temperature controller, and cryostat vacuum pumping system are used. The system for cooling the X-ray tube, the high-voltage generator, and the helium compressor and pump for maintaining the desired vacuum in the cryostat are replaced. The system for controlling the primary beam shutter is upgraded. A biological shielding is installed. The new program tools, which use the Linux Ubuntu operating system and SPEC constructor, include a set of drivers for control units through the aforementioned interfaces. A program for searching reflections from a sample using fast continuous scanning and a priori information about crystal is written. Thus, the software package for carrying out the complete cycle of precise diffraction experiment (from determining the crystal unit cell to calculating the integral reflection intensities) is upgraded. High quality of the experimental data obtained on this equipment is confirmed in a number of studies in the temperature range from 20 to 300 K.

UbuntuWorld 1.0 LTS — A Platform for Automated Problem Solving and Troubleshooting in the Ubuntu OS

In this paper we present UbuntuWorld 1.0 LTS — a platform for developing automated technical support agents in the Ubuntu operating system. Specifically, we propose to use the Bash terminal as a simulator of the Ubuntu environment for a learning-based agent, and demonstrate the usefulness of adopting reinforcement learning (RL) techniques for basic problem solving and troubleshooting in this environment. We provide a plug-and-play interface to the simulator as a python package where different types of agents can be plugged in and evaluated, and provide pathways for integrating data from online support forums like Ask Ubuntu into an automated agent’s learning process. Finally, we show that the use of this data significantly improves the agent’s learning efficiency. We believe that this platform can be adopted as a real-world test bed for research on automated technical support.

Modeling the delivery of security advisories and CVEs

This empirical paper models three structural factors that are hypothesized to affect the turnaround times between the publication of security advisories and Common Vulnerabilities and Exposures (CVEs). The three structural factors are: (i) software product age at the time of advisory release; (ii) severity of vulnerabilities coordinated; and (iii) amounts of CVEs referenced in advisories. Although all three factors are observed to provide only limited information for statistically predicting the turnaround times in a dataset comprised of Microsoft, openSUSE, and Ubuntu operating system products, the paper outlines new research directions for better understanding the current problems related to vulnerability coordination.

FILE SHARING SERVER MENGGUNAKAN SAMBA SERVER DAN LINUX UBUNTU 12.04 SERVER

Data storage on server laboratory at the computer science when needed.It was because application that progressively and document required was handled by more than one person.Currently there are 6 class space the laboratory contained 30 units of computer in each room. All the time, Laboran (person who manage and work in a laboratory) have to bring harddrive external if you want to install application needed for each the lab, but during this laboran has only two external hard drive. This condition resulted in the process of installation application in the laboratory require a long time. In addition, every month laboran have to make recapitulation contract for 22 person laboratory’s assistant. Now, to make contract assistant in the lab, laboran have to open one of the workstations that is in the fasilkom’s laboratory. This can slow performance, because laboran have to coming into the fasilkom’s laboratory. By the presence of the problems mentioned above, then built a file sharing that is used to hold the application of which is required in the entire room of Fasilkom’s laboratory. In addition, a file sharing this can be used to speed up the emoluments of the preparation of reports on the whole lab assistant that until now had been stored luminance space laboratory so that laboran no need to use more external hard disk in installation perform the process of application by opening the Samba through Windows Server Explorer. It is also the case to compile the report honorarium of the lab’s assistant, laboran enough to use of a file sharing fastly. A file sharing development is using the Linux Ubuntu operating system Version 12.04 and the application of the Samba Servers the Samba to connect storage a file that is in linux so that it can be opened in a windows or linux operating system based. Keywords : File Sharing Server, Samba Server, Linux Ubuntu, Computer Lab.

A Decision Support System to Choose Optimal Release Cycle Length in Incremental Software Development Environments

In the last few years it has been seen that many software vendors have started delivering projects incrementally with very short release cycles. Best examples of success of this approach has been Ubuntu Operating system that has a 6 months release cycle and popular web browsers such as Google Chrome, Opera, Mozilla Firefox. However there is very little knowledge available to the project managers to validate the chosen release cycle length. We propose a decision support system that helps to validate and estimate release cycle length in the early development phase by assuming that release cycle length is directly affected by three factors, (i) choosing right requirements for current cycle, (ii) estimating proximal time for each requirement, (iii) requirement wise feedback from last iteration based on product reception, model accuracy and failed requirements. We have altered and used the EVOLVE technique proposed by G. Ruhe to select best requirements for current cycle and map it to time domain using UCP (Use Case Points) based estimation and feedback factors. The model has been evaluated on both in-house as well as industry projects.
