T-government for benefit realisation

This paper proposes a model for t-Government and highlights the research agenda needed to increase understanding of transformational government and the processes involved in furthering the agenda of the t-Government. In particular, both an operational and a conceptual model for the effective involvement of citizens and businesses in government functioning have been proposed. This will help to define an agenda for t-Government research that emerges from national UK strategy and policy for e-Government. The main threads of t- Government encompass: (1) A citizen-centric delivery of public services or e-inclusion, (2) A shared services culture to maximize value added to clients, (3) The effective delivery and management of resources and skills within government or professionalism. All three threads should be addressed principally from the perspectives of delivery, evaluation and participation in view of benefit realisation as envisioned by Government strategic planning and policy directives (CabinetOffice, 2005). The management of change dimension of these phenomena have been included in the research agenda. In particular, research is needed to reshape the discourse towards emphasising a citizen centric approach that defines, develops, and benefits from public service. Decision makers in Government will need models of Governance that fulfil transformational objectives. They will also need models of benefits realisation within a strategic Governance framework. It has been argued that t-Government research should be addressing these relative voids

Optical properties of ZnO nanocrystals embedded in PMMA

We report in this work the preparation of thin films of ZnO nanocrystals synthesized and dispersed in polymethylmethacrylate using a easy route and deposited in class substrate by spin coating technique. Their structural and optical properties were investigated by X-ray, absorption and photoluminescence spectroscopy. The XRD patterns exhibit sharp peaks at 2θ corresponding to the hexagonal (wurtzite) phase diffraction planes. The optically characterization, exhibit a wide absorption band in the range of the study and a large emission band with three peaks at 481.5, 531.09 and at 671.28 nm.The crystallites radius (R) was estimated by applying the effective mass approximation model and was about 1.8 nm. From measurements of second order susceptibilities using harmonic generation technique at λ=1,064 nm  in picoseconds regime we deduced λ2eff equal to 5.95×10−10  m/V. Obtained λ2eff was four order of magnitude larger compared with ZnO bulk material (2.5 pm/V)

On Non Commutative Calabi-Yau Hypersurfaces

Using the algebraic geometry method of Berenstein et al (hep-th/0005087), we reconsider the derivation of the non commutative quintic algebra ${\mathcal{A}}_{nc}(5)$ and derive new representations by choosing different sets of Calabi-Yau charges ${C_{i}^{a}}$. Next we extend these results to higher $d$ complex dimension non commutative Calabi-Yau hypersurface algebras ${\mathcal{A}}_{nc}(d+2)$. We derive and solve the set of constraint eqs carrying the non commutative structure in terms of Calabi-Yau charges and discrete torsion. Finally we construct the representations of ${\mathcal{A}}_{nc}(d+2)$ preserving manifestly the Calabi-Yau condition $\sum_{i}C_{i}^{a}=0$ and give comments on the non commutative subalgebras.Comment: 16 pages, Latex. One more subsection on fractional branes, one reference and minor changes are added. To appear in Phy. Let.

Integration of IT in building design and technology: a systems engineering framework

Most concepts of systems engineering (SE) offer a systematic approach to the adaptation of procedures, tools, and standards toward an information-oriented problem in order to analyze, to design, to develop, to manage and to finally implement an effective and a pragmatic integrated information technology solution. This paper proposes a systems engineering framework for integrating information technology (IT) in building design and development. The system view is based on SE good practice and corresponding SE standards. All lifecycle for systems development is covered ranging from the operational concept to operation and maintenance and disposal. The paper is focused mainly at the requirement engineering levels and validation verification issues. In addition, this paper involves a case-study with an important setup where the simulated results are obtained within the use of distributed control and building performance simulation software by run-time coupling. The case-study is also developed in an effective way to illustrate the integration of IT in building design

Épandage des margines sur les sols agricoles : impacts environnementaux microbiologiques

L’épandage agricole des margines (effluents des moulins à huile d’olive) constitue une alternative parmi les solutions permettant de les valoriser, mais à condition que cette opération soit contrôlée et maîtrisée enrespectant les doses à appliquer. Cependant, une réticence envers l’épandage demeure jusqu’à nos jours, pour des craintes d’éventuelles incidences microbiologiques négatives sur le sol. Ainsi, pour contribuer à soulever l’ambiguïté qui a dû résulter des avis souvent controversés envers la valorisation agricole des margines, ce travail a été mené au niveau d’une exploitation agricole. En comparaison avec un sol non traité aux margines (témoin), les impacts environnementaux microbiologiquesde l’épandage de 25 et 50 m3/ha ont été étudiés, pendant quatre mois, au niveau de deux horizons (0-20 cm et 20-40 cm) d’un sol homogène de texture sable limoneux. Les résultats obtenus ont révélé que les phénols provenant des margines ont été dégradés ou réorganisés au cours du deuxième mois après l’épandage. Ni activation, ni inhibition de l’activité de la microflore du sol n’ont été constatées suite à l’épandage des doses étudiées.Mots-clés : margines, épandage, environnement, impacts  microbiologiques

Synthesis, photophysical and photochemical properties of oxazolone derivatives

Acyloxyphenyl derivatives of oxazolone, which have tree photo active centers, were synthesized and their physicochemical properties are determined by NMR, absorption, fluorescence excitation and emission spectroscopies. The semi-empirical calculations carried out according with the theory of the PM3/Cl level has shown, that at an irradiating of their solutions by UV-light give no possibilities of the photo-Fries reaction. The calculated values are in a good accordance with the experimental ones

Optimization of liquid crystal structures for real time holography applications

In this paper we present results of experiments designed to increase our understanding of the photorefractive effect occurring during processes of dynamic hologram generation in Hybrid Photorefractive Liquid Crystal Structures (HPLCS). We also propose equivalent mathematical model which can be used to optimize those structures in order to obtain the highest diffraction efficiency in possibly shortest time.
