Initial Results

Home networks are becoming more and more popular. Today's state of the art is that several different technologies, like Wireless LAN (WLAN), Power Line Communication (PLC), or Ethernet, are being used concurrently to connect home devices. If any connection fault happens, the communication stops and new connectivity has to be established. Since the fault detection can last several seconds, it reduces the "Quality of Experience" dramatically, and ongoing transmissions can be disturbed. Therefore, reliability of transmission is a necessary precondition to fulfil customers' expectations. In our approach, we suggest an additional protocol layer, dubbed layer 2.5, which manages any available connectivity and automatically chooses a new connection with the correct properties, for instance HDTV stream. It balances load situations and can also be used to intelligently distribute traffic between nodes. The system has been proven to work in standard LINUX kernel implementation with a speed up to 1 Gb/s and with an extreme low latency. The topology control and signalling components have been implemented in LINUX user space and work on best effort bases. Within this paper, we outline the architectural considerations and show the initial results. The work has been used as the starting point for a new IEEE standardization, i.e., IEEE1905.1. This group started with the OMEGA I-MAC architecture, introduced here. The work described here has received funding from the European Commission's Seventh Framework Programme FP7/2007-2013 under grant agreement no. 213311, also referred to as OMEGA.

The Way

There must be a reason why an experience feels the way it does. A good place to begin addressing this question is spatial experience, because it may be more penetrable by introspection than other qualities of consciousness such as color or pain. Moreover, much of experience is spatial, from that of our body to the visual world, which appears as if painted on an extended canvas in front of our eyes. Because it is ‘right there’, we usually take space for granted and overlook its qualitative properties. However, we should realize that a great number of phenomenal distinctions and relations are required for the canvas of space to feel ‘extended’. Here we argue that, to be experienced as extended, the canvas of space must be composed of countless spots, here and there, small and large, and these spots must be related to each other in a characteristic manner through connection, fusion, and inclusion. Other aspects of the structure of spatial experience follow from extendedness: every spot can be experienced as enclosing a particular region, with its particular location, size, boundary, and distance from other spots. We then propose an account of the phenomenal properties of spatial experiences based on integrated information theory (IIT). The theory provides a principled approach for characterizing both the quantity and quality of experience by unfolding the cause-effect structure of a physical substrate. Specifically, we show that a simple simulated substrate of units connected in a grid-like manner yields a cause-effect structure whose properties can account for the main properties of spatial experience. These results uphold the hypothesis that our experience of space is supported by brain areas whose units are linked by a grid-like connectivity. They also predict that changes in connectivity, even in the absence of changes in activity, should lead to a warping of experienced space. To the extent that this approach provides an initial account of phenomenal space, it may also serve as a starting point for investigating other aspects of the quality of experience and their physical correspondents.

The purpose of this research is to know the influence between the Quality of Human Resources, Utilization of Information Technology and Internal Control System Against Timeliness of Village Government Financial Reporting at Gunungkidul Regency. This research is causative research. The population is the village government in Gunungkidul Regency, especially in Gedangsari subdistrict. Criteria of respondents in the study were to village and village apparatus. We use questionnaire to collect data. We use multiple regression with SPSS program version 16.0 to analyze data. We find that quality of human resources and internal control system have a positive influence on the timeliness of village government financial reporting. On the other hand, utilization of information technology does not influence the timeliness of village government financial reporting. These imply that the quality of human resources and internal control system can speed up the preparation of village government financial reporting.

A great number of cheese dairies and dairy industries in Greece are disposing their wastes, mainly cheese whey, either on land or in surface receivers, in large quantities creating a major environmental problem. A typical agricultural and pastoral provincial town of 70,000 inhabitants, Trikala, became the starting point of this research. A co-treatment of the urban sewage and the dairy wastes in the municipal treatment plant was recommended. The successful application of the above statement is based primarily on the pretreatment of the cheese dairies wastes. So far for cheese whey the recovery of the lactose serum in the contemporary central unit applying membrane technology has been suggested. As far as the wastewaters of the washing and refrigeration are concerned a pretreatment is required for the defatting in a grease trap, the grating, the adjustment of pH and the equalisation in an appropriate tank. Finally, this research has also focussed on the importance of membrane technology in improving the quality of milk and cheese production.

Abstractlearning process  good teaching  can create a situation that allows children to learn, so that is the starting point of the success of teaching. The low quality of education depends on the management of the teaching and learning process which can be interpreted as being less effective in the teaching and learning process, the causes: (1) Low learning activities, (2) Inadequate facilities and infrastructure. The case in Solok City Middle School, the low level of student learning activities allegedly influenced the low student learning outcomes. Based on observations on class VIII A which included the superior class had not yet achieved the desired completeness, the class with the least completeness was class VIII B which was 33.33% with KKM 65 criteria. Seeing this reality, teachers were required to motivate students and foster enthusiasm student learning. Therefore, to foster students' enthusiasm for learning, the author tries to apply student learning activities through discussion methods in small groups.Keywords: Learning, discussion AbstrakProses belajar mengajar yang baik dapat menciptakan situasi yang mmemungkinkan anak belajar, sehingga merupakan titik awal keberhasilan pengajaran. Rendahnya mutu pendidikan tergantung pada pengelolaan proses belajar mengajar yang dapat diartikan kurang efektifnya proses belajar mengajar, penyebabnya: (1) Rendahnya aktifitas belajar,  (2) Sarana dan prasarana yang belum memadai. Kasus pada SMP Negeri % Kota Solok rendahnya aktifitas belajar siswa diduga berpengaruh terhadap rendahnya hasil belajar siswa. Berdasarkan pengamatanpada  kelas VIII A yang termasuk kelas unggul belum mencapai ketuntasan yang di inginkan, sedangkan kelas yang paling sedikit ketuntasannya adalah kelas VIII B yaitu sebanyak 33,33 % dengan kriterian KKM 65. Melihat kenyataan tersebut, guru dituntut untuk dapat memotivasi siswa dan menumbuhkan semangat belajar siswa. Karena itu, untuk menumbuhkan semangat belajar siswa, penulis mencoba untuk menerapkan aktivitas belajar siswa melalui metode diskusi dalam kelompok kecil. Kata kunci: Pembelajaran, diskusi

Run Time

Smartphone users require high Battery Cycle Life (BCL) and high Quality of Experience (QoE) during their usage. These two objectives can be conflicting based on the user preference at run-time. Finding the best trade-off between QoE and BCL requires an intelligent resource management approach that considers and learns user preference at run-time. Current approaches focus on one of these two objectives and neglect the other, limiting their efficiency in meeting users’ needs. In this article, we present UBAR, User- and Battery-aware Resource management, which considers dynamic workload, user preference, and user plug-in/out pattern at run-time to provide a suitable trade-off between BCL and QoE. UBAR personalizes this trade-off by learning the user’s habits and using that to satisfy QoE, while considering battery temperature and State of Charge (SOC) pattern to maximize BCL. The evaluation results show that UBAR achieves 10% to 40% improvement compared to the existing state-of-the-art approaches.
