On Topological Chaos in the Robinson-Solow-Srinivasan Model
Full text linkIn this paper, we offer an instance of (topologically) chaotic optimal behavior in a twosector model with irreversible investment, originally formulated by Robinson, Solow and Srinivasan. Our result follows from the theory of turbulence in non-linear dynamical systems, and relies only on the existence of a continuous optimal policy function. The fact that there is a unique optimal program from each initial stock when future utilities are discounted by a factor smaller than the labor-capital ratio may be of independent interest.
Shashank Srinivasan: Conservation Technologies in India
No full text<p>In this episode, we speak to Shashank Srinivasan, founder of <a href="https://atlas.smartforests.net/en/logbooks/technology-for-wildlife-foundation/">Technology for Wildlife Foundation</a> based in Goa, India. Shashank discusses the use of drones, satellites, and geospatial mapping to amplify conservation work, while also remaining critical of the potential negative social and environmental impacts of these technologies.</p>

Optimal materials selection for bimaterial piezoelectric microactuators
Full text linkPiezoelectric actuation is one of the commonly employed actuation schemes in microsystems. This paper focuses on identifying and ranking promising active material/substrate combinations for bimaterial piezoelectric (BPE) microactuators based on their performance. The mechanics of BPE structures following simple beam theory assumptions available in the literature are applied to evolve critical performance metrics which govern the materials selection process. Contours of equal performance are plotted in the domain of the governing piezoelectric material properties ( coefficients, elastic modulus, coupling factors and dielectric constants) for commonly employed substrates to identify optimal material combinations for various functional requirements. The influence of materials selection on the actuation efficiency, quality factor and the electromechanical impedance is also discussed. Selection of a suitable actuation mechanism for a boundary layer flow control application is illustrated by comparing the performance limits of BPE and bimaterial electrothermal actuators considering the constraints on the functional requirements imposed by the associated microfabrication routes

Bringing Semantics to Web Services: The OWL-S Approach
No full textService interface description languages such as WSDL, and related standards, are evolving rapidly to provide a foundation for interoperation between Web services. At the same time, Semantic Web service technologies, such as the Ontology Web Language for Services (OWL-S), are developing the means by which services can be given richer semantic specifications. Richer semantics can enable fuller, more flexible automation of service provision and use, and support the construction of more powerful tools and methodologies. Both sets of technologies can benefit from complementary uses and cross-fertilization of ideas. This paper shows how to use OWL-S in conjunction with Web service standards, and explains and illustrates the value added by the semantics expressed in OWL-S
