A design model applied to development of AmI systems

Also published online by CEUR Workshop Proceedings (CEUR-WS.org, ISSN 1613-0073)Proceedings of the I International Conference on Ubiquitous Computing: Applications, Technology and Social Issues Alcalá de Henares, Madrid, Spain, June 7-9, 2006.Ambient intelligence (AmI) represents a promising paradigm for group-centred collaborative interaction with the surrounding environment. The complexity for AmI designs is closely connected with the mechanism for describing their inherent features. What would be interesting is a method which is capable of describing these properties in a straightforward way. Task modelling techniques are a suitable method for AmI systems. This paper describes a new design and implementation proposal for developing AmI systems, starting from the conceptual and methodological frameworks proposed by AMENITIES, a methodology based on task and behaviour models for the study and development of cooperative systems, extending it with inherent AmI features. With respect to the implementation of AmI systems, an intermediate software layer supporting common functional requirements is supplied in order to simplify their development. The overall scheme therefore simplifies the analysis and development of such systems. These features are shown in a case study of a collaborative e-learning AmI systemThis research is partially supported by a Spanish R&D Project TIN2004-03140, Ubiquitous Collaborative Adaptive Training (U-CAT)

Pembangunan Aplikasi Perhitungan Honor Dan Pengukuran Kinerja Asisten Praktikum Berbasis SaaS

Bagi suatu perguruan tinggi, kegiatan praktikum sangat penting untuk mendukung pembelajaran di kelas. Beberapa masalah yang muncul dalam pengelolaan kegiatan praktikum seperti keterlambatan pengumpulan berita acara praktikum (BAP) sehingga memperlambat perhitungan, pembayaran dan pelaporan honor asprak. Dibutuhkan waktu sekitar dua minggu untuk rekapitulasi dan validasi ratusan lembar BAP yang telah terkumpul setiap bulannya. Dibutuhkan pengolahan data lebih lanjut untuk menilai kinerja asprak berdasarkan data BAP. Untuk mengatasi permasalahan di atas maka dibangun aplikasi perhitungan honor dan kinerja asprak. Aplikasi ini digunakan untuk mengelola data BAP, perhitungan dan pelaporan honor, perhitungan nilai transkrip aktivitas kemahasiswaan (TAK) dan pencetakan sertifikat asprak. Keterbatasan SDM atau biaya menyebabkan tidak semua perguruan tinggi dapat langsung membuat aplikasi yang dibutuhkan. Oleh karena itu aplikasi ini dibangun berbasis Software as A Service (SaaS). Aplikasi ini dikembangkan dengan metode analisis perancangan terstruktur dengan model waterfall. Pengumpulan data kebutuhan aplikasi dilakukan dengan survey ke fakultas-fakultas di Universitas Telkom. Hasilnya dianalisis dan dikembangkan menjadi rancangan aplikasi. Aplikasi diimplementasikan pada pemrograman PHP. Pengujian dilakukan dengan metode black box testing. Hasilnya berupa aplikasi SaaS untuk perhitungan honor dan pengukuran kinerja asisten praktikum. Perguruan tinggi pengguna aplikasi SaaS ini dapat melakukan kostumisasi terhadap fitur yang ada sesuai dengan kebutuhan

Hubungan Antara Konsep Diri Dengan Kesepian Pada Remaja (Studi Korelasi Pada Siswa Kelas IX SMP Negeri 2 Semarang)

Penelitian ini bertujuan untuk mengetahui hubungan antara konsep diri dengan kesepian pada remaja awal. Konsep diri adalah pandangan, evaluasi, dan penilaian mengenai diri sendiri oleh individu yang bersangkutan. Kesepian merupakan keadaan psikologis yang timbul akibat adanya ketidaksesuaian ideal dengan Kenyataan dalam membina hubungan dengan orang lain. Teknik sampling yang digunakan adalah teknik cluster random sampling. Populasi dalam penelitian ini adalah siswa kelas IX SMP Negeri 2 Semarang. Sampel penelitian berjumlah 150 siswa. Alat pengumpul data yang digunakan adalah skala konsep diri dan skala kesepian. Kedua skala disusun berdasarkan teori psikologi yang ada dan melalui proses uji coba. Proses tersebut menunjukkan koefisien reliabilitas skala konsep diri sebesar α=0,884 dan skala kesepian sebesar α=0,907. Analisis data menggunakan teknik analisis regresi sederhana. Hasil yang diperoleh adalah ada hubungan yang negatif signifikan antara konsep diri dengan kesepian yang ditunjukkan oleh koefisien korelasi (rxy) sebesar 0,765 dan p=0,000 (p<0,05). Semakin tinggi konsep diri maka semakin rendah kesepian, demikian pula sebaliknya semakin rendah konsep diri maka semakin tinggi kesepian pada siswa. Sumbangan efektif konsep diri terhadap kesepian sebesar 58,5% dan sisanya 41,5% dijelaskan oeh faktor-faktor lain

Development of ambient intelligence systems based on collaborative task models

So far, the Ambient Intelligence (AmI) paradigm has been applied to the development of a great variety of real systems. They use advanced technologies such as ubiquitous computing, natural interaction and active spaces, which become part of social environments. In the design of AmI systems, the inherent collaboration among users (with the purpose of achieving common goals) is usually represented and treated in an ad-hoc manner. However, the development of this kind of systems can take advantage of rich design models which embrace concepts in the domain of collaborative systems in order to provide the adequate support for explicit or implicit collaboration. Thereby, relevant requirements to be satisfied, such as an effective coordination of human activities by means of task scheduling, demand to dynamically manage and provide group- and context-awareness information. This paper addresses the integration of both proactive and collaborative aspects into a unique design model for the development of AmI systems; in particular, the proposal has been applied to a learning system. Furthermore, the implementation of this system is based on a blackboardbased architecture, which provides a well-defined high-level interface to the physical layer.This research is partially supported by a Spanish R&D Project TIN2004-03140, Ubiquitous Collaborative Adaptive Training (U-CAT)

The importance of international exchanges of plant genetic resources for national crop improvement in Costa Rica

One of the main considerations underlying the establishment of the International Treaty on Plant Genetic Resources for Food and Agriculture and its Multilateral System of Access and Benefit Sharing is the recognition of countries’ high interdependence on the genetic resources of the crops and forages which they depend upon for their food security. A continued appreciation of how countries have benefited from facilitated exchange of germplasm in the past and are likely to continue doing so in the future is needed, in order to move forward the implementation of the Multilateral System and creating a truly global pool of genetic resources for countries’ agricultural development and adaptation to climate change. Using Costa Rica as a case and rice and bean as key crops, the paper presents a picture of the dynamics of their genetic resources, both inside and outside of the country, over past years and into the future. It illustrates the extent to which Costa Rica is dependent upon germplasm from other countries for its food security, and how, in a complementary manner, other countries rely upon germplasm from Costa Rica. It is hoped that the information presented here may encourage and facilitate the implementation of the International Treaty and its Multilateral System in the country

Dynamical decoherence in a cavity with a large number of two-level atoms

We consider a large number of two-level atoms interacting with the mode of a cavity in the rotating-wave approximation (Tavis-Cummings model). We apply the Holstein-Primakoff transformation to study the model in the limit of the number of two-level atoms, all in their ground state, becoming very large. The unitary evolution that we obtain in this approximation is applied to a macroscopic superposition state showing that, when the coherent states forming the superposition are enough distant, then the state collapses on a single coherent state describing a classical radiation mode. This appear as a true dynamical effect that could be observed in experiments with cavities.Comment: 9 pages, no figures. This submission substitutes paper quant-ph/0212148 that was withdrawn.

Measurement models for time-resolved spectroscopy: a comment

We present an exactly solvable model for photon emission, which allows us to examine the evolution of the photon wavefunction in space and time. We apply this model to coherent phenomena in three-level systems with a special emphasis on the photon detection process.Comment: 14 pages RevTex, 4 figure

AMENITIES (a conceptual and methodological framework based on task-based models) has been specially devised for collaborative systems and is the starting point for a new design proposal for application to AmI systems. This paper proposes a task-based model for designing collaborative AmI systems, which attempts to gather the computational representation of the concepts involved (tasks, laws, etc.) and the relationships between them in order to develop a complete functional environment in relation with the features of AmI systems (collaborative, context-aware, dynamic, proactive, etc.). The research has been applied to an e-learning environment and is implemented using a blackboard model.This research is partially supported by a Spanish R&D Project TIN2004-03140, Ubiquitous Collaborative Adaptive Training (U-CAT)
