Response to UML 2 0 request for information

Response to UML 2 0 request for information

A language is defined by its syntax AND semantics. The semantics is given by a mapping from the syntax (domain) to a semantics domain. Both syntax and semantics domains may have concrete representations. There may be many concrete representations for any particular element from either domain. Some concrete representations may be used to represent elements from both domains. For example, in the UML, a sequence diagram may be used to specify general behaviour of operations (it is a concrete representation of some ‘sentence’ of the UML), or it may be used to represent a specific trace of that behaviour (it is a concrete representation an element in the semantics domain). A set of concrete representations of elements from the syntax domain (often referred to as expressions and sentences) has traditionally been called a concrete syntax. The term abstract syntax has then been used to distinguish the syntax domain from concrete syntax. We will continue to use these terms. It is also worth stressing that every component of the language definition has well-formedness (wf) rules. For example, the UML 1.3. meta-model has a number of these rules expressed as constraints in OCL.

Response Time Analysis of Mobile Application DNUN in New Relic Monitoring Platform

Response Time Analysis of Mobile Application DNUN in New Relic Monitoring Platform

We use the New Relic software as a monitoring platform to analyse the performance of DNUN. Response time in DNUN is a crucial factor in saving those individuals in danger. As a result, we work on studying and analyzing this factor to improve the DNUN design, if needed, through reducing the response time to its minimal. New Relic delivers real-time and crucial information about the performance of the web app from the minute that user starts browsing until the page completes its loading. After the user sign up for an account and install the New Relic program (known as agent) in the server, it begins to monitor and collect all network and database activities. Response time [7] is the metric that APM uses to measure the reliability of DNUN.

Crowdsourcing environmental sustainability : where 2 0 Australia? : Implications of GeoWeb 2 0 for broad based community participation in environmental information sharing

create” as opposed to previous modes of “planning and pushing” (Tapscott & Williams 2008). The former stance was adopted, with engagement with research participants to co-create the research from the outset. The methodology and methods were initially chosen as aligning with this approach, as well as based on my understanding of environmental sustainability, and ethical concerns. They then evolved throughout the research in response to what was found and where I was situated. For the sake of simplicity, I have divided this evolution into two distinct, yet interconnected and interrelated stages. In Stage 1, Participant Action Research (PAR) was used to engage with participants online and offline, while in Stage 2 there was less emphasis on others’ participation and more on observation. The research methodology moved from PAR to Action Research, in which participant co-direction lessened and participant observation increased. Overall the approach was qualitative and I describe how aspects of this tradition of research are appropriate. The thesis structure and a narrative writing style were also chosen as best matching the methodology, recursive evolution and emergent design of the research. The results of Stage 1 are presented in Chapters 4 and 5, and are structured following the six recursive PAR cycles that were conducted. Chapter 4 describes the results of PAR cycles 1-3, engaging participants predominantly online within free GeoWeb 2.0 services (FGW2S) adapted by myself. Chapter 5 describes PAR cycles 4-6, participation in wider contexts and how wider perspectives on GeoWeb 2.0 were developed. Throughout, I reflect upon how the activities and developments informed the research aims and objectives. These reflections included the use of methodology and methods, and how the experiences of the research influenced subsequent directions. This shows how both the research direction and methodology evolved in response to what was encountered.

Information quality in Web 2 0

Information quality in Web 2 0

information quality criteria might be affected by the implementation of a pattern. This does mean that the pattern in question should be duly implemented and the right format should be chosen. It is also that not each pattern is applicable in each context. The specific contexts in which an implementation is feasible are documented in the ‘Context’ section of each pattern. It appears in this matrix that the Declaration of Failure is the most powerful pattern, targeting the most possible problems. This is true, but the pattern is mostly applicable in Collaborative Content Creation contexts. The Splitter pattern has a lot of possible desirable side effects, but the side effects may be achieved by various implementations. A splitting on a repository level may have positive effects on Response Time and Availability, whereas a splitting information object level may have a positive effect on Response Time and Efficiency. However, the most noted effects are Conciseness and Completeness. It is also clear that the Process-pragmatic criteria are not often the target of the patterns. This is caused by the scope of the research, which focuses on Web 2.0, while problems with Process- pragmatic information quality criteria do occur in all websites. Therefore, patterns to solve these problems are outside of the scope.

Investigating the impact of the Request For Information process in construction

Investigating the impact of the Request For Information process in construction

The common element between all RFIs is the associated lost-time as a result of the process. Compounding this above cost impact, is the tracking the RFIs through the use of the register and chasing responses, this consumes resources and therefore time and cost. In today’s society when organisations are typically under resourced, as opposed to over resourced, it is common for RFI responses to be late, vague, possibly missing important pieces of information and sometimes late or forgotten if they are not chased properly. Section 3.6.6 refers to Appendix G which is a further case study into late RFI responses on a particular project that forms part of the sample, referring to Appendix G shows the common late RFIs are on projects. These problems lead to the need for contractors to re-issue of the same (or similar) query on a revised RFI which exaggerates the time and cost spent to a higher degree (Mohamed, Tilley & Tucker 1998).

Object Oriented Query Response Time for UML Models

Object Oriented Query Response Time for UML Models

A UML sequence diagram represents the dynamic be- havior of system which is shown in Figure 2. It shows the sequence of executions represented through object life line. In the current work a UML sequence diagram is designed which shows that the complete process of sending information about the premium due of the issued policy plan through executing a query whose premium is due. The four main objects are Main_Branch, Query, Mobile_System and Customer. Arrow along the commu- nication message shows the communication between two objects. The vertical line alongwith the pipe shows that the life line of an object. The Main_Branch executes a query to get the list of customers whose premium of the issued policy is due, the Main_Branch send information on the Customer’s Mobile_System; the Customer inter- acts with that information and deposit the due premium amount. The main purpose of this diagram is to check whether the designed model is functioning or not.

A pattern based approach to defining the dynamic infrastructure of UML 2 0

A pattern based approach to defining the dynamic infrastructure of UML 2 0

The power of designing software independent of an implementation has become well established in recent years with the development of modelling notations such as the Unified Modelling Language (UML) [1]. The UML enables the designer of a system to reify requirement-oriented descriptions of a system to an implementation through a number of models. Consequently there can be increased certainty that the implementation accurately reflects the requirements. Despite this, the lack of precision within the current version of the UML semantics can compromise this certainty and result in a flawed implementation. This need for precision has been recognised by the Object Management Group’s requests for proposals (RFPs) for the next major revision of UML (version 2.0). The RFPs require that a precise infrastructure be defined for UML 2.0. The intention is that all UML modelling notations will be built upon the infrastructure such that there can be no ambiguity concerning the meaning of the notations and their relationship to each other.

Integrating Performance Characterization with Software Development

Integrating Performance Characterization with Software Development

Considering that UML is gaining more consensus as the de facto modeling framework used by most software engineers, more emphasis has been given to transforming UML system models into their corresponding performance models. The Object Management Group (OMG) [10] leads the process of developing standard UML profiles for annotating UML models with performance information. The profile of Schedulability, Performance and Time (SPT) was the first OMG profile for real-time systems adopted in 2005 [15]. It uses tagged-values to annotate UML 1.4 models with the required performance attributes. The OMG profile for Modeling and Analysis of Real Time and Embedded systems (MARTE) then came to replace the SPT profile [11][14]. The MARTE profile supports UML 2.0 and provides more flexibility in defining performance values using the Value Specification Language (VSL).

Integrating Existing Safety Analyses into SysML

Integrating Existing Safety Analyses into SysML

In 2017 the OMG issued a Request for Proposals on how to represent fault trees in SysML as part of the Safety and Reliability Analysis Profile for UML, which will extend the SysML language with “the capability to model safety information, such as hazards and the harms they may cause, model reliability analyses, including Fault Tree Analysis (FTA) and Failure Mode and Effects Analysis (FMEA), and use structured argument notation to organise the model and specify assurance cases”[2]. As part of this, an early profile for Fault Tree Analysis (FTA) and Failure Mode and Effects Analysis (FMEA) has been devel- oped and published [2] and is likely to form part of SysML 2.0. However, while the new profile is moving in the right direction, it isn’t sufficiently defined to be adopted for use on the development of UltraFan within Rolls-Royce and neither is it likely to support the specific requirements for Rolls-Royce to model engine dispatch availability. Our work attempts to bridge this current gap in SysML capability by providing a bespoke SysML profile to support Rolls-Royce’s Fault Tree and Time Limited Dispatch (TLD) analyses.

REVERSE ENGINEERING: AN ESSENCE FOR SOFTWARE RE-ENGINEERING AND PROGRAM ANALYSIS.

REVERSE ENGINEERING: AN ESSENCE FOR SOFTWARE RE-ENGINEERING AND PROGRAM ANALYSIS.

Testing decompiler tools with the current java features revealed the areas where these tools failed to produce correct results as it is shown in chapters 4 and 5. It is evident that among these various tools, so far java decompiler – jd-gui has performed well with jad and jdec-2.0 left behind. UML reverse engineering outcome from the UML tools we have used in our study, ALTOVA U-Model and Enterprise Architect from Sparx Systems reveal same structural information about java code as the compiled bytecode with input once taken as source decompiled form the decompiler tools and original Test programs next, which further ascertains the sufficiency of static bytecode analysis for the original code structure recovery by using reverse engineering tools.

Mapping UML 2 0 Activities to Zero Safe Nets

Mapping UML 2 0 Activities to Zero Safe Nets

Example 4. In Figure 3, we give a naïve basic Petri net that formalizes the AD of Figure 1. The transcription follows mapping rules defined by Storrle in [3] (See Ta- ble 1). The author added a number of transitions, model- ing the interruption event, equal to the cancelled actions in the region. Each transition is connected to the input place of a cancelled action and to transition Cancel Or- der via an output common place. When the Cancel Order Request is made, places of the Interruptible Activity Re- gion, with dark gray, have to be emptied.

An enhanced UML consistency checker using logical approach

An enhanced UML consistency checker using logical approach

Spanoudakis & Zisman (2001) define consistency as a state in which two or more overlapping elements of different software models make assertion about the aspects of the system they describe which are jointly satisfiable. While, Shinkawa (2006) defines a set of UML model as consistent when there are no conflicts between two arbitrary UML diagrams. On the other hand, a UML model is inconsistent when it violates the constraints (Hubaux, et al., 2009, Sourrouille & Caplat, 2004, Spanoudakis & Zisman, 2001). It is important to ensure that a UML model is consistent as it is one of the attributes used in measuring the quality of a UML model (Nugroho & Chaudron, 2008). UML consistency is classified into horizontal or intra- model consistency, vertical or inter-model consistency, syntactic consistency, and semantic consistency (Elaasar & Briand, 2004, Huzar, et al., 2005, Lucas, et al., 2009, Mens, et al., 2005b, Usman, et al., 2008). In horizontal or intra-model consistency, consistency is validated at a same level of abstraction between different UML diagrams, while in vertical or inter-model consistency, consistency of different UML diagrams are validated at different level of abstraction (Huzar, et al., 2005). Meanwhile, syntactic consistency confirming a UML diagram towards its abstract syntax, while semantic consistency validating semantic compatibility of diagram’s behaviour (Huzar, et al., 2005). Syntactical consistency includes the well-formedness rules described as a constraint in UML Superstructure Specification (Object Management Group (OMG), 2011b). Table 2.1 below shows Lucas et al. (2009) giving concrete example of each consistency.

Intelligent Mobile Ad-Hoc Routing Methodology with Modified Routing Procedures  Sathish Kumar,  Dr.S.Purushothaman  Abstract PDF  IJIRMET1602010001

Intelligent Mobile Ad-Hoc Routing Methodology with Modified Routing Procedures Sathish Kumar, Dr.S.Purushothaman Abstract PDF IJIRMET1602010001

Findings:Mobile Ad-Hoc Networks (MANET) a fast growing network scheme and it provides various features for communication strategies and routing protocols. Theses routing protocols are introduced to avoid the attacker nodes and provides the efficient communication between source and destination. The attacks in the network scenarios are: DOS, Wormhole attack and Blackhole attacks. In this system, a new routing protocol strategy is defined by means of RREQ and RREP Strategies with the help of Optimized Link State Identification Routing (OLSIR). Source Node sends Route Request (RREQ) to the nearby node. The nearby node checks the request and sends the Route Response (RREP) to Source Node back within a proper interval. The proper and relevant response from the neighbor node indicates it as a proper node as well as the neighbor node sequence Number will get incremented by 1. The node is proper then only the count will be incremented otherwise it consists attack content. This kind of nodes are properly blocked from the present scenario and the source checks for the alternate or other neighbor nodes to proceed for further communications. As per the regular network strategies the node selection or path selection process is purely based on Shortest Path Routing methodology.

P6 acupoint stimulation for prevention of postoperative nausea and vomiting in patients undergoing craniotomy: study protocol for a randomized controlled trial

P6 acupoint stimulation for prevention of postoperative nausea and vomiting in patients undergoing craniotomy: study protocol for a randomized controlled trial

Background: The incidence of postoperative nausea and vomiting (PONV) is 50 to 79% after neurosurgery. Our study is designed to evaluate the efficacy of pericardium 6 (P6; also known as Neiguan) acupoint stimulation versus placebo, and versus routine antiemetic for the prevention of PONV after craniotomy, as well as to compare the efficacy of invasive acupuncture with non-invasive transcutaneous electrical nerve stimulation (TENS) on P6. Methods/design: This is a single-center, prospective, double-blind, five-arm, parallel-group, randomized controlled trial (RCT). All groups will be given routine intravenous ondansetron 8 mg administered before skin closure. Upon regaining consciousness from general anaesthesia, patients will receive one of five interventions: 1) P6 acupuncture bilaterally for 30 minutes, stimulated every 10 minutes to keep de qi sensation; 2) sham acupuncture bilaterally for 30 minutes with no stimulation; 3) P6 stimulation via active TENS electrodes bilaterally for 30 minutes, with stimulation frequency and intensity set to when de qi sensation is felt; 4) sham P6 stimulation via inactive TENS electrode bilaterally for 30 minutes; and 5) usual practice of pharmacological emesis prevention. The incidence of postoperative vomiting during the first 24 hours is the main outcome. Secondary outcomes include: complete response rate, severity of nausea, total rescue metoclopramide dose used and patient satisfaction with PONV management.

Analysis of crosscutting concerns in QVT-based model transformations

Analysis of crosscutting concerns in QVT-based model transformations

However, the place where the Persistence concern causes more problems is the transformation definition. The case study contains several transformation rules in which all classes marked with persistent custom property are transformed to Java classes with necessary methods for retrieving data from and saving data to storage media. Apparently, these rules become much more complex as they use not only information from source and target metamodels, but also information on how to realize the Persistence concern. The situation is worse when this information is represented in a textual form but not modeled in a graphical model as in MDA development framework. This consequently leads to the difficulty in reusing the rules in other applications involved with the Persistence concern. The changes in the Persistence concern also cause these rules modified instead of only re-executing them, and have an impact on other dependent rules.

Humanitarianism 2 0

Humanitarianism 2 0

The scale of the problem is hard to estimate with confidence. For example, observers put the proportion of ‘fake’ Twitter accounts (i.e. accounts that are not what they purport to be because they are controlled by users who disguise their true identities or are linked with ‘bots’ rather than people) between 5 and 10%. Similarly, the number of fake Facebook accounts has been estimated to be between 5 and 10%. The relationship between fake accounts and trustworthiness of social media content is not easily established, however. Many of these fake accounts seem to exist primarily for the purpose of boosting the follower counts of other users; indeed there is a healthy market in this. Such practices are not necessarily innocuous, however, since the number of followers is often used as a proxy or rule of thumb for the trustworthiness of a social media source. Estimates of untrustworthy content vary; a study of the Bombay terrorist attack of 2011 concluded that only 17% of the total tweets posted contained information that was credible (Gupta et al. 2012). A similar study of social media during the Boston bombing of 2013 concluded that 29% of the most viral content were rumours (Gupta et al. 2013a).

The Generator 2 0

The Generator 2 0

At this point in the project, although the generator was able to offer novel configurations for its users, the rules of the system were still ‘designed’ by Price. However, further design iterations explored the possibility of Generator being able to generate its own layout proposals if it became ‘bored’. The Generator would “continually try to stimulate proposals for change. If the buildings do not receive any response, the computer declares itself bored and produces unsolicited plans for the occupants to consider anyway” (Stansell 1981). John and Julia Frazer therefore assisted in developing the software to enable random re-configuration should the layout remain in stasis for a certain amount of time.

Towards business integration as a service 2 0 (BIaaS 2 0)

2.2 Linkage comparisons: BIaaS vs. Supply Chain Rungtusanatham et al. [18] introduced the concept of linkages for supply chain, and they define it as “explicit and/or implicit connections that a firm creates with critical entities of its supply chain in order to manage the flow and/or quality of inputs from suppliers into the firm and of outputs from the firm to customers.” There is another type of information-based linkage that can improve the visibility of customers’ and suppliers’ operational activities [12]. Barratt and Barratt [2] present their external and internal supply chain linkages and use a Coffee case study to demonstrate linkages in relationship and business activities between different roles and companies. Although they show a workflow diagram, data analysis and three propositions, their presentation is still a conceptual framework without any implementations or services in place.
