This chapter describes Aneka-Federation, a decentralized and distributed system that combines enterprise Clouds, overlay networking, and structured peer-to-peer techniques to create scalable wide-area networking of compute nodes for high-throughput computing. The Aneka-Federation integrates numerous small scale Aneka Enterprise Cloud services and nodes that are distributed over multiple control and enterprise domains as parts of a single coordinated resource leasing abstraction. The system is designed with the aim of making distributed enterprise Cloud resource integration and application programming flexible, efficient, and scalable. The system is engineered such that it: enables seamless integration of existing Aneka Enterprise Clouds as part of single wide-area resource leasing federation; self-organizes the system components based on a structured peer-to-peer routing methodology; and presents end-users with a distributed application composition environment that can support variety of programming and execution models. This chapter describes the design and implementation of a novel, extensible and decentralized peer-to-peer technique that helps to discover, connect and provision the services of Aneka Enterprise Clouds among the users who can use different programming models to compose their applications. Evaluations of the system with applications that are programmed using the Task and Thread execution models on top of an overlay of Aneka Enterprise Clouds have been described here.

Energy generation, along with other sectors of Russia’s economy, is on the cusp of the era of digital transformation. Modern IT solutions ensure the transition of industrial enterprises from automation and computerization, which used to be the targets of the second half of the last century, to digital enterprise concept 4.0. The international record of technological and structural solutions in digitization may be used in Russia’s energy sector to the full extent. Specifics of implementation of such systems in different countries are only determined by the level of economic development of each particular state and the attitude of public authorities as related to the necessity of creating conditions for implementation of the same. It is shown that a strong legislative framework is created in Russia for transition to the digital economy, with research and applied developments available that are up to the international level. The following digital economy elements may be used today at enterprises for production of electrical and thermal energy: — dealing with large amounts of data (including operations exercised via cloud services and distributed data bases); — development of small scale distributed generation and its dispatching; — implementation of smart elements in both electric power and heat supply networks; — development of production process automation systems, remote monitoring and predictive analytics; 3D-modeling of parts and elements; real time mathematic simulation with feedback in the form of control actions; — creating centres for analytical processing of statistic data and accounting in financial and economic activities with business analytics functions, with expansion of communication networks and computing capacities. Examples are presented for implementation of smart systems in energy production and distribution. It is stated in the paper that state-of art information technologies are currently being implemented in Russia, new unique digital transformation projects are being launched in major energy companies. Yet, what is required is large-scale and thorough digitization and controllable energy production system as a multi-factor business process will provide the optimum combination of efficient economic activities, reliability and safety of power supply.

Purpose The purpose of this paper is to demonstrate the usefulness of the “audience exchange” approach for audience development and research, and to highlight the insights offered by peer-to-peer dialogue in understanding experiences of unfamiliar arts. Design/methodology/approach Using a case study with contemporary arts audiences, and setting this in the wider context of studies with other first-time attenders at a range of arts events, the paper explores the use of the “audience exchange” method, in which facilitated conversations after performance events allow newcomers to reflect upon and deepen their first-time encounters with live arts. Findings The study demonstrates the way in which conversations about arts events can enrich audience experience, and shows how participants use exploratory and emotional language to articulate their understanding of unfamiliar arts events. Peer-to-peer learning occurs through these conversations, in ways that could be further supported by arts organisations as a valuable tool for audience development. The audience exchange discussions also reveal the varieties of participation from “drifting” to full attention that are all part of audience engagement. Research limitations/implications This is a small-scale, qualitative study, and the method has potential to be tested in future studies with a greater variety of participants (e.g. younger or more ethnically diverse groups). Practical implications Use of the audience exchange for enriching experiences of first-time attendance could be adopted by arts organisations as a regular part of their audience engagement. Greater understanding of how new audience members draw on prior cultural experiences in finding the language to articulate their first impressions of an unfamiliar arts event could be valuable for targeted marketing and increasing accessibility. Originality/value The originality of this study lies in its elaboration of the audience exchange method, and its focus on the language and peer-to-peer learning evident in the facilitated post-performance discussions.

Atlas of the Baltic Languages: Plant Names of Slavonic OriginThe article investigates Slavonic-derived plant names in dialects of the two surviving Baltic languages – Latvian and Lithuanian. Historically, these Slavonisms were originally adopted by small-scale regional dialects, which are now disappearing. In 2009, a pilot study for the Atlas of the Baltic Languages was published. It comprised 12 geo-linguistic maps with Latvian, Lithuanian and English commentaries. 2012 saw the publication, in CD format, of the Atlas’s first volume: Lexis 1: Flora. The material analysed concerns names for: (1) wild plants, e.g., cornflower, nettle, waybread, milfoil, dandelion, plantain; (2) cultivated plants, e.g., onion, potatoe, garlic, cucumber, Swedish turnip, [winter] wheat; (3) trees (juniper, hazel-tree, pear-tree, plum-tree, cherry-tree, etc.) and words related to a tree (top of the tree, cone, etc.).Borrowed plant names can generally be grouped as follows: 1. Common borrowings located in a wide area in Lithuania and used all over Eastern part of Latvia – the region of Latgale. These usually denote fruits and vegetables, e.g. the potatoe (Solanum tuberosum) – Latv. buļve and its variants, buļba and variants, uļbiks / Lith. bulvė and variants, bulbė and variants; or garlic – casnags, casnāgs and variants / Lith. česnākas, šešnākas and variants. 2. Common borrowings located in wide area in Lithuania and used in some subdialects in Latgale, e.g. Lith. vosilka / Lat. Vasilka ‘cornflower (Centaurea cyanus)’; Lith. kriváunykas and variants / Lat. kravavņiks and variants ‘yarrow (Achillea millefolium L.)’. 3. Slavonisms whose origin differs in Latvian and in Lithuanian, e.g. Lat. klevers (< Russ. клевер, Bel. dialectal клéвер, клевiр / Lith. kaniušina < Bel. канюшына, Pol. koniczyna for ‘clover (Trifolium)’.The Atlas of the Baltic Languages, reflecting the language contacts, could be an important source for further investigation not only in Baltistics but also in Slavistics and Indo-European comparative linguistics.Атлас балтийских языков: названия растений славянского происхожденияВ статье рассматриваются названия растений славянского происхождения в диалектах единственнo живых балтийских языков – латышского и литовского. Исторически эти славянизмы были заимствованы региональными территориальными диалектами, которые в настоящее время исчезают. В 2009 г. был опубликован пилотный проект Атласа балтийских языков, включающий 12 геолингвистических карт с комментариями на латышском, литовском и английском языках. В 2012 г. первый том атласа: Атлас балтийских языков. Лексика I: Флора – был опубликован в формате CD. Связанную с растительним миром лексику представляют названия, обозначающие: 1) дикорастущие растения – например, василек, крапиву, подорожник, тысячелистник, одуванчик, 2) культурные растения – например, лук, картофель, репу, (зимнюю) пшеницу, и 3) деревья (можжевельник, орешник, грушу и др.), а также части деревьев (макушку дерева, шишку). В качестве основных групп заимствованных названий растений можно выделить: 1. Общие заимствования, которые встречаются в широком ареале в Литве и во всей восточной части Латвии – в Латгалии. Обычно это названия овощей и фруктов, например, картофеля (Solanum tuberosum) – лат. buļve и вар., buļba и вар., uļbiks / лит. bulve и вар., bulbe и вар., чеснока: лат. casnags, casnāgs и вар./ лит. česnākas, šešnākas и вар. 2. Общие заимствования, которые встречаются в широком ареале в Литве и в некоторых говорах Латгалии, например, лит. vosilka / лат. vasilka ‘вaсилёк (Centaurea cyanus)’, лит. kriváunykas и вар. / лат. kravavņiks и вар. ‘тысячелистник (Achillea millefolium L.)’. 3. Славянизмы несовпадающего проиcхождения в латышском и литовском языках, например, лат. klevers (< рус. kлевер, бел. диал. клéвер, клевiр) / лит. kaniušina < бел. kанюшына, поль. koniczyna ‘клевер (Trifolium)’. Атлас балтийских языков отражает языковые контакты и служит важным источником для дальнейших исследований не только в балтистике, но также в славистикe и индоевропейском сравнительном языкознании.

Transmission Failures

An emergency neurosurgical teleradiology system was initially installed in two referring hospitals in Ireland to transmit images to the neurosurgical department in Cork. It was subsequently expanded to six major referring hospitals transmitting to both neurosurgical departments in Ireland serving the entire population of 3.5 million people, effectively becoming a national teleradiology system. The system was based on PCs interconnected by leased data circuits and ISDN. The network was operational 24 hours a day. Over 750 emergency computerized tomography scans were transmitted and transmission failures occurred in only 6% of cases. We conclude that current PC technology can be used to form a peer-to-peer wide-area network upon which a robust emergency teleradiology system can be based.
