This work concerns the stress-state identification, produced by loads or dislocations, of statically indeterminate structures. In particular, this paper deals with the case of pin-jointed trusses, since they are a combination of simplicity of the structural model with very interesting technical applications. We present an approach that follows the main guidelines of the flexibility method to re...

The new training literature suggests that in a monopsonistic market employers will not only pay for fi rm-specifi c training but also for general training if the risk of poaching is limited. This implies that training participation should decrease when competition for employees is higher among fi rms. Using worker level data for Germany we fi nd that the hypothesis is supported empirically. Spe...

β-lactamases are bacterial enzymes that confer resistance to β-lactam antibiotics, such as penicillins and cephalosporins. There are four classes of β-lactamase enzymes, each with characteristic sequence and structure properties. Enzymes from class A are the most common and have been well characterized across the family; however, less is known about how physicochemical properties vary across th...

This chapter describes marketing strategies in concept for wireless broadband services in the Sri Lankan market. It also emphasizes different technologies offering fixed and mobile broadband services. Wi-Fi services which are mentioned here has been on offer for few years but actual marketing of such services are not actively done in Sri Lanka. Various marketing strategies that could be used to...

This paper studies the statistical errors for the fingerprint-based RADAR neighbor matching localization with the linearly calibrated reference points (RPs) in logarithmic received signal strength (RSS) varying Wi-Fi environment. To the best of our knowledge, little comprehensive analysis work has appeared on the error performance of neighbor matching localization with respect to the deployment...

To think quantitatively about comovement, we specify the model of Section I. We use a CES production function for one final good. 42 Thus, we can solve the structure of this economy in closed form, and quantify its comovement. Our model differs in a series of small ways from 43 Its main virtue is that it is solvable in closed form, so that the mechanisms are fairly transparent.

This thesis deals with the solving of multiple friction contact problems between deformable bodies in the specific area of interactive simulation with force feedback. The general context of this work is the training of medical-surgical gestures via an haptic device. In this type of context, it is often necessary to take into account the global deformations of the organs and the local contact fo...

I describe two studies that were designed to illustrate the potential applicability of laboratory-derived ESP effects in trying to predict events of practical consequence in the “real world.” Both studies attempt to predict the behavior of sets of fi nancial indices over a designated week in the future. The studies followed up on earlier work on the prediction of scoring direction and scoring e...
