AbstractWe present a modification of the spring‐embedder model of Eades [Congressus Numerantium, 42, 149–160, (1984)] for drawing undirected graphs with straight edges. Our heuristic strives for uniform edge lengths, and we develop it in analogy to forces in natural systems, for a simple, elegant, conceptually‐intuitive, and efficient algorithm.

AbstractCloud computing is a recent advancement wherein IT infrastructure and applications are provided as ‘services’ to end‐users under a usage‐based payment model. It can leverage virtualized services even on the fly based on requirements (workload patterns and QoS) varying with time. The application services hosted under Cloud computing model have complex provis...... hiện toàn bộ

SummaryInternet of Things (IoT) aims to bring every object (eg, smart cameras, wearable, environmental sensors, home appliances, and vehicles) online, hence generating massive volume of data that can overwhelm storage systems and data analytics applications. Cloud computing offers services at the infrastructure level that can scale to IoT storage and processing req...... hiện toàn bộ
AbstractThis paper defines a language called Modula, which is intended primarily for programming dedicated computer systems, including process control systems on smaller machines. The language is largely based on Pascal, but in addition to conventional block structure it introduces a so‐called module structure. A module is a set of procedures, data types and variab...... hiện toàn bộ
AbstractBacktrack algorithms are applicable to a wide variety of problems. An efficient but readable version of such an algorithm is presented and its use in the problem of finding the maximal common subgraph of two graphs is described. Techniques available in this application area for ordering and pruning the backtrack search are discussed. This algorithm has been...... hiện toàn bộ

SummaryMicroservices architectures are becoming the defacto standard for building continuously deployed systems. At the same time, there is a substantial growth in the demand for migrating on‐premise legacy applications to the cloud. In this context, organizations tend to migrate their traditional architectures into cloud‐native architectures using microservices. T...... hiện toàn bộ

SummaryIn the competing era of online industries, understanding customer feedback and satisfaction is one of the important concern for any business organization. The well‐known social media platforms like Twitter are a place where customers share their feedbacks. Analyzing customer feedback is beneficial, as it provides an advantage way of unveiling customer intere...... hiện toàn bộ
AbstractC++ and Concurrent C are both upward‐compatible supersets of C that provide data abstraction and parallel programming facilities, respectively. Although data abstraction facilities are important for writing concurrent programs, we did not provide data abstraction facilities in Concurrent C because we did not want to duplicate the C++ research effort. Instea...... hiện toàn bộ
AbstractIt has become fashionable to criticize nested conditionals, which are supposed to tax the human mind, and to recommend that they should be ‘un‐nested’, turning if‐then‐if into if‐then‐else‐if. Experiment casts doubt on this, however, and suggests that indeed the unnested form is only slightly better in the best conditions and is much worse in unsuitable con...... hiện toàn bộ
AbstractMany mission‐critical, decision‐making situations happen in dynamic, rapidly changing, and often unpredictable environments. Military, governmental, and medical contexts are examples of such situations, which can be characterized by highly decentralized, up‐to‐date data sets coming from various sources. Unlike other decision‐making tools, decision support s...... hiện toàn bộ
