With the most recent releases of MD-JEEP, new relevant features have been included to our software tool. MD-JEEP solves instances of the class of Discretizable Distance Geometry Problems (DDGPs), which ask to find possible realizations, in a Euclidean space, of a simple weighted undirected graph for which distance constraints between vertices are given, and for which a discretization of the search space can be supplied. Since its version 0.3.0, MD-JEEP is able to deal with instances containing interval data. We focus in this short paper on the most recent release MD-JEEP 0.3.2: among the new implemented features, we will focus our attention on three features: (i) an improved procedure for the generation and update of the boxes used in the coarse-grained representation (necessary to deal with instances containing interval data); (ii) a new procedure for the selection of the so-called discretization vertices (necessary to perform the discretization of the search space); (iii) the implementation of a general parser which allows the user to easily load DDGP instances in a given specified format. The source code of MD-JEEP 0.3.2 is available on GitHub, where the reader can find all additional details about the implementation of such new features, as well as verify the effectiveness of such features by comparing MD- JEEP 0.3.2 with its previous releases.

One of the Agile principles is that the team should regularly reflect on"how to become more effective, then tunes and adjusts its behavior accordingly". While the setup of a retrospective session is intuitive, in praxis, conducting successful retrospectives is challenging. This paper is a continuation of our previous work on the use collaborative games in addressing common retrospective problems. In addition to the replication of our previous action research in a new context, we aim to investigate whether preliminary anonymous idea generation mitigates negative social influences that have been identified as causes of poor performance of brainstorming. The obtained results confirms the previous findings that game-based retrospectives produces better results than the standard retrospective as well as improves participants' creativity, involvement, and communication. Our findings also suggest benefits to the preliminary anonymous idea generation.

Popularne obecnie interfejsy dotykowe, pozwalające w prosty sposób sterować maszynami, powstały ponad dwadzieścia lat temu. Obraz wyświetlany był początkowo na ekranach CRT z dołożoną matrycą dotykową. Później pojawiły się ekrany LCD podświetlane awaryjnymi lampami katodowymi. Dzisiaj standardem jest już podświetlenie LED, które jest właściwie niezawodne. Ewolucja interfejsów sterowniczych rozpoczęła się od przeniesienia przycisków mechanicznych z szafy sterowniczej na ekran monitora w formie graficznego odwzorowania.

BACKGROUND: Distance protections are widely used in protection of energy transmission lines, but their time coordination is still an important and difficult problem. Inappropriate configuration leads to a hazard event: remote circuit breaker tripping provided the local circuit breaker can be opened, which severely impairs power system operation. OBJECTIVE: To describe a method and provide software tools to alleviate the hazard in power systems. METHODS: A domain specific language (DSL) for representation of a transmission line with its distance protection schema, and a translation algorithm from the DSL to probabilistic fault trees with time dependencies (PFTTDs) are employed. RESULTS: The paper presents software tools that can support power protection experts in time coordination of distance protections. The tools are based upon abstract and concrete syntax of the DSL designed specifically for the purpose of the distance protection time coordination problem. In order to render creation of power line and its protection schema models easier, a DSL-dedicated editor supporting syntax and semantic aspects of the DSL has been developed. Additionally, a translator from the DSL into PFTTD language has been implemented. CONCLUSIONS: Power system experts are enabled to perform hazard probability assessment and sensitivity analysis. LIMITATIONS: Translation supports two types of distance protections, which are: single-system relays with starting elements as well as multi-system relays without starting elements. For the single-system relay, there is one timer per relay. For multi-system relays, there is one timer for each of possibly many protection zones. Other types of protections, e.g. overcurrent are not considered.

There is presented the application of the integrated software tools to the reliability of the improved exemplary complex technical system prediction. There are considered three ways of the exemplary system reliability improvement, i.e. a hot single reservation of its components, a cold single reservation of its components and replacing its components by the improved components with reduced intensities of departure from the reliability state subsets. Automatically obtained, using the computer program CP 8.16, the evaluations of these ways improved exemplary system unconditional multistate reliability function, the expected values and the standard deviations of its unconditional lifetimes in the reliability state subsets and the mean values of its lifetimes in the particular reliability states are presented. Moreover, in the case when the improved system is repairable, its renewal and availability characteristics are estimated using the computer program CP 8.8 with appropriately given data.

This article identifies new ways to reduce the time between the product idea and its transformation into a functioning production system, taking the whole system one step further towards the ideal completely integrated, rapid product and production development. New methods and opportunities allow for a number of improvements. In order to uncover hidden potential, the required processes must be integrated and shortened. IPA makes use of this approach by involving the various research fields of its institute in a process chain to work on further improvements. This procedure includes a common development environment called the "centre for parallel product and production development" for the step-by-step integration of product and production development processes.
