The purpose of the article is to plan a project of an electric vehicle technicalassistance point. the methodology of the study is to use the critical path method.the scientific novelty of the obtained results is that the article describes the practicalaspects of project planning of the creation of an electric vehicle technical assistancepoint. In particular, the tasks of the project are described, labor, material and financialresources necessary for its realization are specified. conclusions. The implementationof the developed project will effectively manage the content, time and resources ofthe project of the creation of an electric vehicle technical assistance point.

AbstractDavid Chalmers argues that virtual objects exist in the form of data structures that have causal powers. I argue that there is a large class of virtual objects that are social objects and that do not depend upon data structures for their existence. I also argue that data structures are themselves fundamentally social objects. Thus, virtual objects are fundamentally social objects.

To reason with existential rules (a.k.a. tuple-generating dependencies), one often computes universal models. Among the many such models of different structure and cardinality, the core is arguably the “best”. Especially for finitely satisfiable theories, where the core is the unique smallest universal model, it has advantages in query answering, non-monotonic reasoning, and data exchange. Unfortunately, computing cores is difficult and not supported by most reasoners. We therefore propose ways of computing cores using practically implemented methods from rule reasoning and answer set programming. Our focus is on cases where the standard chase algorithm produces a core. We characterise this desirable situation in general terms that apply to a large class of cores, derive concrete approaches for decidable special cases, and generalise these approaches to non-monotonic extensions of existential rules.

Faculty of Medicine University of Riau has been implementing Competency Based Curriculum (KBK) with theProblem Based Learning (PBL) since 2007 with the implementation of teaching and learning activities of the systemconsists of a tutorial activities, skillab, expert lectures, independent and practical. However, there are still manyproblems in the implementation of the KBK on preclinic degree. One part of the block that is identified to be one ofthe causes of low graduation exam block is less efective coaching laboratory practice. Parasitology is one part of thetask is to provide laboratory practice in several blocks on the stage of preclinic especially digestive and hematoimunologyblock. This study aimed to compare the results of the evaluation of parasitology laboratory practice in hematoimunologyand digestive assistance and posttest in large classes with small class. Assistance and posttest in large class performedon the digestive block implementation and hematoimunologi in 2011 while assisting and posttest of small classes ona block implementation in 2012. Average value of small class digestive laboratory practice was not significantlylower than the large class but the proportion of the value of quality B and C more many in small classes. The meanvalue of the block hematoimunologi laboratory practice significantly higher on small class assistance and posttest aswell as the proportion of the value of quality A, B and C was higher in small classes than large classes.

Leap frog concept was created to address the loss of single joint rig agility and drive the cycle time average lower than ever. The idea is to move the preparation step into a background activity that includes moving the equipment, killing the well, dismantling the wellhead and installing the well control equipment/BOP before the rig came in. To realize the idea, a second set of equipment is provided along with the manpower. By moving the preparation step, the goal is to eliminate a 50% portion of the job from the critical path. The practice is currently performed in tubing pump wells on land operations. However, the work concept could be implemented for other type of wells, especially ESP wells. After implementation, the cycle time average went down from 18 hours to 11 hours per job, or down by ~40%. The toolpusher also reports more focused operations due to reduced scope and less crew to work with, making the leap frog operation safer and more reliable. Splitting the routine services into 2 parts not only shortened the process but it also reduces noise that usually appear in the preparation process. The team are rarely seen waiting on moving support problems that were usually seen in the conventional process. Having the new process implemented, the team had successfully not only lowered cycle time, but also eliminated several problems in one step. Other benefits from leap frog implementation is adding rig count virtually to the actual physical rig available on location, and also adding rig capacity and completing more jobs compared to the conventional rig. In other parts, leap frog faced some limitation and challenges, such as: limited equipment capability for leap frog remote team to work on stuck plunger, thus hindering its leap frog capability, and working in un-restricted/un-clustered area which disturb the moving process and operation safety.
