The Software System LingvoDoc and the Possibilities It Offers for Documentation and Analysis of Ob-Ugric Languages

—The LingvoDoc system (http://lingvodoc.ispras.ru) provides a service for collaborative language documentation and computations on the collected data. This software system provides GraphQL HTTP API for all the system components and allows its users to build their own extensions for data analysis or even to integrate it with their own software. Thanks to a special database and application design pattern, it is possible to construct offline applications integrated with the LingvoDoc system: these applications would need to have an internet connection only once to synchronize basic data types and for authentification purposes. The system itself allows users to construct multilayer dictionaries, attach them to the geographical map, fill documents with metadata, share access to dictionaries with other users or with everyone. The LingvoDoc system provides fine-grained access control lists for sharing, which allows to separate users into groups of dictionary editors, proofreaders and read-only users. The system also provides some computational algorithms on the stored data: phonology computations, automatic and guided deduplication inside the dictionaries etc. The system allows users to choose the dictionary structure. The system supports the following data types: text, images, sounds (wav, mp3, and flac), markups (ELAN and Praat formats), directed and undirected links between stored entities. A user can choose the most suitable format for their dictionary. Also, the system provides ELAN corpora storage, viewer and processing. In LingvoDoc there are 13 programs made for authors of the dictionary (only 4 of them are available for all users of the system). These programs analyze language data from phonetical, morphological and etymological point of view. This analysis previously was performed manually by linguists. Our programs allows do it tens and sometimes hundreds times faster. This paper presents the documentation and an analysis of Ob-Ugric languages using the LingvoDoc system.

Investigating Approaches of Integrating BIM, IoT, and Facility Management for Renovating Existing Buildings: A Review

The importance of building information is highly attached to the ability of conventional storing to provide professional analysis. The Internet of Things (IoT) and smart devices offer a vast amount of live data stored in heterogeneous repositories, and hence the need for smart methodologies to facilitate IoT–BIM integration is very crucial. The first step to better integrating IoT and Building Information Modeling (BIM) can be performed by implementing the Service-Oriented-Architecture (SOA) to combining software and other services by replacing the sematic information that was failed to display elements of indoor conditions. The other development is to create link that able to update static models towards real-time models using SOA approach. The existing approach relies on one-way interaction; however, developing two-way communication to mimic human cognitive has become very crucial. The high-tech approach requires highly involving Cloud computations to better connect IoT devices throughout Internet infrastructure. This approach is based on the integration of Building Information Modeling (BIM) with real-time data from IoT devices aiming at improving construction and operational efficiencies and to provide high-fidelity BIM models for numerous applications. The paper discusses challenges, limitations, and barriers that face BIM–IoT integration and simultaneously solves interoperability issues and Cloud computing. The paper provides a comprehensive review that explores and identifies common emerging areas of application and common design patterns of the traditional BIM-IoT integration followed by devising better methodologies to integrate IoT in BIM.

Determination of Data Mining Application Design Patterns Booking Raw Food In Restaurant Fountain With Apriori Algorithm

Booking is an activity carried out by certain parties to ensure availability, in carrying out certain activities the company has a supply of material in quantities that exceed the needs. As a result, in the warehouse there is a buildup of raw materials or it can happen otherwise. Inventories of materials that are too small can hinder the company's operations in the form of unavailability of materials when needed. The role of inventory will determine the operation of the company because the inventory will run well if supported by good management. Therefore, the concept of inventory management that affects ordering is very important to be applied by companies so that the goals of effectiveness and efficiency are achieved. So we need a Data Mining that can quickly to determine the Determination of Food Raw Material Ordering Patterns in Restaurant Fountain Using Apriori. Data Mining is the extraction of new information taken from large chunks of data that helps in making decisions. One of the applications of data mining for Determining the Pattern of Ordering Food Raw Materials in Restaurant Fountain Using Apriori. Apriori method is a method for determining frequent itemsets for boolean association rules. The research aims to build the application of Determining the Pattern of Ordering Food Raw Materials in Restaurant Fountain with a web-based application and as a tool for designing applications using the Mysql Database. This data mining is able to determine the ordering of food items in the Restaurant Fountain with the required amount.

Guiding assurance of architectural design patterns for critical applications

Abstract Development of critical systems nowadays is hardly achievable without reuse of previous knowledge. Design patterns have an important role in the design of such systems as they define and document common solutions to recurring design problems. However, critical systems such as those that are safety or security related, often require specific assurances that the system is adequate to operate in a given environment. Just as with any other reused knowledge in such systems, the reuse via application of design patterns needs to be assured every time. In this paper, we present a methodology for assuring the application of design patterns in critical domains. In particular, we enrich the design patterns template to support their further assurance. We define the aspects that should be tackled during the assurance of a design pattern application. We use the information specified in the design pattern template to guide the automated instantiation of the argumentation for each design pattern application in the system. We provide tool-support for our methodology in the context of the AMASS tool-platform and evaluate it in an automotive case study.

A review of building information modeling (BIM) and the internet of things (IoT) devices integration: Present status and future trends

Abstract The integration of Building Information Modeling (BIM) with real-time data from the Internet of Things (IoT) devices presents a powerful paradigm for applications to improve construction and operational efficiencies. Connecting real-time data streams from the rapidly expanding set of IoT sensor networks to the high-fidelity BIM models provides numerous applications. However, BIM and IoT integration research are still in nascent stages, there is a need to understand the current situation of BIM and IoT device integration. This paper conducts a comprehensive review with the intent to identify common emerging areas of application and common design patterns in the approach to tackling BIM-IoT device integration along with an examination of current limitations and predictions of future research directions. Altogether, 97 papers from 14 AEC related journals and databases in other industry over the last decade were reviewed. Several prevalent domains of application namely Construction Operation and Monitoring, Health & Safety Management, Construction Logistic & Management, and Facility Management were identified. The authors summarized 5 integration methods with description, examples, and discussion. These integration methods are utilizing BIM tools' APIs and relational database, transform BIM data into a relational database using new data schema, create new query language, using semantic web technologies and hybrid approach. Based on the observed limitations, prominent future research directions are suggested, focusing on service-oriented architecture (SOA) patterns and web services-based strategies for BIM and IoT integration, establishing information integration & management standards, solving interoperability issue, and cloud computing.

Time Complexity of an Distributed Algorithm for Load Balancing of Microservice-oriented Applications in the Cloud

Microservice architecture is a relatively new cloud application design pattern. Each microservice has a single responsibility in terms of functional requirement, and that can be managed independently from other microservices. This is done using automated cloud orchestration systems. In this paper we analyze the time complexity of an simple swarm-like decentralized load balancing algorithm for microservices running inside OpenVZ virtualization containers. We show that it can offer performance improvements with respect to the existing centralized container orchestration systems.

A Semantic Publish-Subscribe Architecture for the Internet of Things

This paper presents a publish-subscribe architecture designed to support information level interoperability in smart space applications in the Internet of Things (IoT). The architecture is built on top of a generic SPARQL endpoint where publishers and subscribers use standard SPARQL Updates and Queries. Notifications about events [i.e., changes in the resource description framework (RDF) knowledge base] are expressed in terms of added and removed SPARQL binding results since the previous notification, limiting the network overhead and facilitating notification processing at subscriber side. A novel event detection algorithm, tailored on the IoT specificities (i.e., heterogeneous events need to be detected and continuous updates of few RDF triples dominate with respect to more complex updates), is presented along with the envisioned application design pattern and performance evaluation model. Eventually, a reference implementation is evaluated against a benchmark inspired by a smart city lighting case. The performance evaluation results show the capability to process up to 68k subscriptions/s triggered by simple single-lamp updates and up to 3.8k subscriptions/s triggered by more complex updates (i.e., 10 to 100 lamps).

Use of Design Patterns According to Hand Dominance in a Mobile User Interface

User interface (UI) design patterns for mobile applications provide a solution to design problems and can improve the usage experience for users. However, there is a lack of research categorizing the uses of design patterns according to users’ hand dominance in a learning-based mobile UI. We classified the main design patterns for mobile applications and investigated their relationships with major learning tasks. Students’ use of different patterns was compared with respect to hand dominance. A questionnaire on 71 patterns was administered to 92 participants, and the number of patterns they used was analyzed. UI design patterns for mobile learning significantly differed between left- and right-hand-dominant participants. We also performed a cluster analysis to explore possible theme sets among participants with regard to hand dominance in learning. The results revealed three-cluster solutions for both the left- and right-hand-dominant groups. We profiled these solutions based on insights obtained from structured interviews. Our findings provide evidence that pattern use differs between right- and left-hand-dominant users with regard to reading, information retrieval, and information-browsing tasks. These findings will facilitate further development of suitable UIs for educational mobile applications.

Validating Design Patterns for Mobile Groupware Applications by Expert Users: a USAER Case

The objective of this research work was to analyze the pertinence of a set of design patterns for mobile groupware applications. The pertinence of said contribution was supported by 11 participant members of an educational support group (USAER). The perception of expert users is commonly used in Human- Computer Interaction to improve and validate design strategies such as the proposed one. In this case the feedback provided by the participants helped to ensure that the knowledge offered by the set of patterns is adequate and accurate. A distilled feedback would lead to well-designed user interfaces for mobile groupware applications.

A design proto‐pattern for continuously evaluated forecasting in IBM® InfoSphere® Streams

SummaryDesign patterns relieve much of the difficulty of developing software solutions. As sources and volumes of generated data have increased in recent times, stream computing has emerged as a new paradigm for acquiring and harnessing the data's rich potential to provide insight in near real time. One prominent platform for processing streaming data is IBM® InfoSphere® Streams, but design patterns for the platform are relatively scarce. This article proposes a prototypical application design pattern for continuously evaluated forecasting on the IBM InfoSphere Streams platform. Towards demonstrating the prototypical pattern, the application was implemented in three real‐world scenarios: wind power, sentiment analysis, and stock market data. The purpose of this article is to specify the design proto‐pattern and describe its variants in each different implementation. We believe that the proto‐pattern will be applicable in IBM InfoSphere Streams to any data stream where forecasts over multiple forecast horizons are required.

Substitute and Communication Pattern for an Internet Banking System

The design patterns are the reusable component used in the development of the software, which delivers enhanced quality software to the end users. The design patterns are available for user interface, mobile applications, text classification and so on. There are no design patterns for internet banking applications. This motivated to mine the design patterns for internet banking application from the document of Business Process Management (BPM) by using the qualitative research technique. The nonfunctional quality attribute of software architecture is enhanced by using the design patterns. In this paper the mined two patterns are presented namely substitute pattern and communication pattern for internet banking application.

Overview of UI Patterns on Mobile Platform for Educational Applications

Software development is currently experiencing significant growth, and the need to improve user interfaces is an important factor. Given this situation, interface design patterns have emerged as a new means of improving the user experience. However, their use has not been adequately studied for use in specific domains such as education. For this reason, it is necessary to analyze design patterns for mobile applications in order to determine the best design patterns for improving the quality and usefulness of applications, more specifically in educational environments. Having this into account, this paper presents an analysis and classification of mobile UI patterns in order to understand their applicability for the educational domain. We present a comparative table of mobile UI patterns implemented on several platforms.

Design patterns for user interface for mobile applications

The topic of this paper is a collection of user interface (UI) design patterns for mobile applications. In the paper we present the structure of the patterns collection – the patterns are suggested solutions to problems that are grouped into a set of problem areas that are further grouped into three main problem areas – a structure which is valuable both as an index to identifying patterns to use, and it gives a fairly comprehensive overview of issues when designing user interfaces for mobile applications. To show the breadth of the patterns collection we present six individual problems with connected design patterns in some detail – each coming from different problem areas. They represent important and relevant problems, and are on different levels of abstraction, thus showing how patterns may be used to present problems and solutions on different levels of detail. To show the relevance and usefulness of the patterns collection for usability professionals with a mixed background, we present some relevant findings from a validation of the patterns collection. In addition to verifying the relevance and usefulness of the patterns collection, it also shows both expected and surprising correlations between background and perceived relevance and usefulness. One important finding from the validation is an indication that the patterns collection is best suited for experienced UI developers wanting to start developing mobile UIs. Using a patterns collection for documenting design knowledge and experience has been a mixed experience, so we discuss pros and cons of this. Finally, we present related work and future research.

Design of Networked Embedded Systems: An Approach for Safety and Security

This paper presents a safety and security-based approach to networked embedded system design that offers reusable design patterns for applications dedicated to various domains. After introducing dependability requirements for embedded system applications, it deals with industrial, sensor-based applications development support aiming at distributed components interconnected by wired Internet compatible intranets and wireless sensor networks. The paper discusses a safety and security-driven approach to embedded system design for an industrial class of Internet-based applications. It focuses on an integrated networking that stems from the IEEE 1451.1 smart transducer interface standard, which is an object-based networking model supporting client-server and publish-subscribe communication patterns in group messaging, and from the IP multicast communication, all together mediating safe and secure access to smart sensors through Internet and ZigBee. The case study demonstrates how clients can access groups of wireless smart pressure and temperature sensors and valves through Internet effectively using developed system architecture while respecting prescribed requirements for application dependent safety and security.

Analysis and Modeling of Servo Motor Controls in Military Vehicle Control Systems Update

Abstract : This paper covers the analysis of various concepts that are used to implement Servo Motor Control in military vehicular control systems. A survey of existing hard real-time servo controls and applicable design patterns is presented. These design patterns along with their critical parameters are identified and described. Potential solutions are created from combinations of design patterns and parameter choices. The solutions are modeled with plausible parameters to identify parameter sensitivities. As the modeling progresses, the solutions' frequency responses, sensitivities and functional performance are also evaluated. This paper concludes with a summary of architectural guidelines.

Comparing the template method and strategy design patterns in a genetic algorithm application

We present a genetic algorithm software project that serves to give students direct experience with choosing among multiple potentially applicable design patterns. We carefully constructed this project to illustrate the power of design patterns in supporting encapsulation while at the same time providing a single context in which to compare and contrast similar design pattern alternatives.

Integrated design patterns for database applications

Design patterns describe solutions for design problems that occur repeatedly in the development of software systems. Software system builders increasingly recognize the importance of exploiting design knowledge and successful experiences in the engineering of new systems. As a result, design patterns have started to gain popularity in capturing software design knowledge and software designs themselves. Currently, design patterns have addressed some of the object-oriented design limitations such as the difficulty in specifying reusable designs. Database applications have both structural and dynamic properties. However, design patterns for structural and dynamic properties are usually discussed separately without much integration. In this paper, we propose design patterns to provide solutions for some important common requirements in database applications. Most of these patterns address the structural and dynamic properties of database applications on an integrated basis. These patterns can be used in the design process as well as the design verification process.
