Design of Global Positioning System (GPS) receiver with a low noise amplifier (LNA) in the front end remains a major design requirement for the success of modern day navigation and communication system. Any LNA is expected to meet the requirements like its ability to add the least amount of noise while providing sufficient gain, perfect input and output matching, and high linearity. However, mo...

abstract o ur basic aim in this paper concerns the question that if overusing the information technology by service and manufacturing firms can increase the total productivity resulting from this kind of technology regarding the iran's economic structure and conditions. for this purpose, we primarily evaluate the productivity resulting from the rate of firms' use of it for the differe...

We show how to obtain high level descriptions of human behavior in terms of physical activity, speech activity, face-to-face interaction (f2f), physical proximity, and social network attributes from sensor data. We present experimental results that show that it is possible to identify individual personality traits as well as subjective and objective group performance metrics from low level data...

structural and environmental complexity and also competitive challenges make priotrizing of technology development so critical for policy makers, managers and industries planner. although the necessity of this subject has been mentioned in literature, but there is not any specific process for technology planning at industry level. because of  this theoretical gap, researches uses the technology...

This paper describes the addition of an extra piece of software, a rollback manager, to implement state saving and rollback management for optimistic federates in the High Level Architecture (HLA). This mechanism uses computational reflection techniques to create a rollback manager metaobject that extends the low-level time management services provided by HLA. The main propose of the rollback m...

In many control applications, a speciic set of output tracking controllers of satisfactory performance have already been designed and must be used. When such a collection of control modes is available, an important problem is to be able to accomplish a variety of high level tasks by appropriately switching between the low-level control modes. In this paper, we deene a concept of control modes, ...

The recent studies in the distributed simulation area are focused in the High Level Architecture, defined by the DoD/USA, which proposes a standard environment to develop and run distributed simulations. The HLA components are designed to ensure a high level of interoperability among simulations and, also, to allow maximum component reusability. This paper proposes a new mechanism to help optim...

V is medicatrix naturae. Latin, from Greek, originally attributed to Hippocrates, translated as “the healing power of nature.” One of the core principles of the integrative medicine philosophy. We value nature and natural healing. We strive for homeostasis, for balance. We laud the healing powers of our planet and lament the erosion of her natural resources. Ecologically sustainable medicine—bu...
