We examine statistical and directional properties of the ambient noise in the 10-100 Hz frequency band from the NPAL array. Marginal probability densities are estimated as well as mean square levels, skewness and kurtoses in third octave bands. The kurotoses are markedly different from Gaussian except when only distant shipping is present. Extremal levels reached approximately 150 dB re 1 micro...

This paper aims to interpret Demand-Side Management (DSM) activity and to point out its problems, adopting micro economics as an analytical tool. Two major findings follow. First, the cost-benefit analysis currently in use has the following problems: (i) inconsistency in cost comparison between utility costs on the supply-side and utility costs plus customer costs on the demand-side, (ii) incon...

This paper reports on the state-of-the-art of technologies for the design and fabrication of MEMS micro-mirrors. We discuss the major design issues, considerations, calculations and restrictions of micro mirrors. The materials employed for the reflective surfaces are described along with their properties. The materials used for the static and dynamic MEMS micro structures as well as the differe...

purpose: the aim of this study was to evaluate the effect of two gingival finishing lines (90° shoulder and deep chamfer) on the marginal fitness of two types of full anatomic all-ceramic crowns; zirconia crowns (zikonzhan) and glass ceramic crowns (ips e-max cad) milled with cad/cam system. materials and methods: two dentoform teeth of left maxillary first molar were prepared with chamfer fini...

Objectives: The aim of this study was to evaluate the structural microporosity (MP) and marginal gap (MG) different flowable composite resins placed with instruments using micro-computed tomography (μCT). 
 Materials Methods: Standard Class II MOD cavities were prepared on 108 lower third molar teeth. Three resins; Filtek Bulk-fill, SDR Bulk-fill I-Flow conventional resin applied a sharp e...

introduction: marginal seal integrity is important for a successful adhesive dental restoration. alterations caused by laser irradiation in the enamel and dentin surface can affect the marginal integrity of adhesive restorations. the aim of this study was to evaluate the microleakage of a composite resin restoration in primary teeth following laser irradiation of enamel and dentin. methods: for...

Several Phillips curves based on sticky information and prices are estimated compared using Bayesian VAR-GMM. This method derives expectations in each curve from a VAR estimates the parameters coefficients simultaneously. Quasi-marginal likelihood-based model comparison selects dual stickiness which, period, some remain unchanged, consistent with micro evidence. Moreover, is more plausible sour...

Acknowledgement: I appreciate the constructive comments of Andrew Austin and three anonymous referees for the Journal of Economic Education. Abstract I present a brief classroom demonstration illustrating Bertrand price undercutting. The classroom demonstration is appropriate for Micro Principles, and both intermediate and upper level undergraduate, as well as graduate classes in micro, Industr...
