The cone of Betti tables over three non-collinear points in the plane
Iulia Gheorghita,Steven V Sam
Mathematics , 2014,
Abstract: We describe the cone of Betti tables of all finitely generated graded modules over the homogeneous coordinate ring of three non-collinear points in the projective plane. We also describe the cone of Betti tables of all finite length modules.
Shape memory actuators - potentials and specifics of their technical use and electrical activation
J. Strittmatter a,b,P. Gümpel,V. Gheorghita
Journal of Achievements in Materials and Manufacturing Engineering , 2012,
Abstract: Due to a martensitic phase change shape memory alloys can revert to their original shape by heating when they undergo an appropriate treatment. Actuator elements with this shape memory effect can show a significant design change combined with a considerable force. Therefore they can be used to solve many technical tasks in the field of actuating elements and mechatronics. These intelligent materials will play an increasing role in the next years, especially within the automotive technology, energy management, power and mechanical engineering as well as medical technology. In order to use the potential of these materials in an optimal way it is necessary to know and understand the extraordinary and unconventional properties of shape memory alloys.This paper will present the commonly used systems of shape memory alloys of today including their performance characteristics and will explain the basics of the shape memory effect in a vivid way. A multitude of application possibilities of shape memory actuators will be presented, in particular the research and development projects that have been carried out at the Konstanz University of Applied Sciences during the last years. In this way a solid state heat engine and an intramedullary nail for bone elongation will be presented as well as various adaptive systems for automotive safety and comfort systems, driven by shape memory elements. Regarding the applications in the automotive field a special focus will be given to different electrical activations to enable very fast contraction times of the shape memory components.

Towards Cloud to Device Push Messaging on Android: Technologies, Possibilities and Challenges  [PDF]
Jarle Hansen, Tor-Morten Gr?nli, Gheorghita Ghinea
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2012, DOI: 10.4236/ijcns.2012.512089
Abstract: In this paper we look at different push messaging alternatives available for Android. Push messaging provides an important aspect of server to device communication, and we specifically focus on the integration of cloud computing with mobile devices through the use of push-based technologies. By conducting a benchmarking test, we investigate the performance of four relevant push technologies for the Android platform, namely C2DM, XMPP, Xtify and Urban Airship. The comparison focuses on three aspects of the libraries: 1) The stability; 2) Response times; and 3) Energy consumption. The test is conducted on both WLAN and 3G, and includes several mobile device types. Additionally, we also integrate with the Google App Engine to provide the cloud integration server that is responsible for sending push messages to the mobile devices.
The preliminary cytogenetic investigations in Rana ridibunda Pall. and Rana esculenta L. from the north of Moldavia

Abstract: The cytogenetic investigations in Rana ridibunda (Pall.) and R. esculenta (L.) species pointed out that the two species have the karyotype formed of 13 pairs of chromosomes (2n = 26). The chromosomes of these species can be divided into two groups: the first group comprises the pairs of large chromosomes 1–5, and the second group is made of the pairs 6–13 of smaller chromosomes.

Abstract: The decentralization should transfer some attributions and services to the local level. In return, that implies that the local community should be awarded directly either a quota out of all the taxes that are collected from its fiscal territory or the entire amount of some taxes. One solution could be that the di-rect income taxes should be withhold at the local level whereas the indirect taxes should go to the general public Romanian budget for the overall needs of the country.

Abstract: In our paper we intend to explore the possibility of integrating the ABC method of cost calculation with cash based value measure, i.e. the Cash Value Added. Our purpose is to develop an instrument for the management of productive companies that will allow them to administrate the process of value creation at the level of individual products or services.The activity based costing (ABC) method of cost calculation can be extended to the way of allocating the capital costs to individual products and services. In the same time, the value based measures can register the shareholders’ value creation process only at the company level and not for the individual products or services as they lack the information regarding the assignment of capital costs to those products.By integrating the calculus of Cash Value Added in the ABC method we consider that the managers will get an important managerial tool for the efficient allocation of the investment capital for the various products or services, given their real profitability, which can be determined by including capital costs in the overall cost of the products or services.
Promoting Game Accessibility: Experiencing an Induction on Inclusive Design Practice at the Global Games Jam
Michael James Scott,Gheorghita Ghinea
Computer Science , 2013,
Abstract: The Global Games Jam (GGJ) attracts many people who are passionate about games development, coming from a range of educational backgrounds. Therefore, the event can be experienced by novices and student developers as an opportunity for learning. This provides an opening to promote themes and ideas that could help form future thinking about games design, emerging as a form of induction on key design issues for new practitioners. Such an approach aims to raise awareness about issues which learners could help develop and take with them into industry. However, the experience itself affords a deep experiential rhetoric and dialogue with experts that could be an effective pedagogical tool for issues seldom addressed deeply in formal educational settings. This paper describes an account by one such individual, being introduced to game accessibility through participation in the GGJ. As such, it is not intended as a rigorous empirical analysis, but rather a perspective on one way a game jam can be experienced, inviting further research on the topic.
Educating Programmers: A Reflection on Barriers to Deliberate Practice
Michael James Scott,Gheorghita Ghinea
Computer Science , 2013,
Abstract: Programming is a craft which often demands that learners engage in a significantly high level of individual practice and experimentation in order to acquire basic competencies. However, practice behaviours can be undermined during the early stages of instruction. This is often the result of seemingly trivial misconceptions that, when left unchecked, create cognitive-affective barriers. These interact with learners' self-beliefs, potentially inducing affective states that inhibit practice. This paper questions how to design a learning environment that can address this issue. It is proposed that analytical and adaptable approaches, which could include soft scaffolding, ongoing detailed informative feedback and a focus on self-enhancement alongside skill development, can help overcome such barriers.
