A new technique for iterative decoding of parallel concatenated convolutional (turbo) codes (PCCC’s) for the correlated fast Rayleigh fading channel is proposed and evaluated. This technique is based upon the use of a multiple differential detector (MDD) receiver structure which exploits the statistical characteristics of the fading process to overcome the effects of the rapid phase and amplitu...

This paper studies the spread of losses and defaults in financial networks with two interrelated features: collateral requirements alternative contract termination rules. When is committed to a firm’s counterparties, solvent firm may default if it lacks sufficient liquid assets meet its payment obligations. Collateral can, thus, increase shortfalls. Moreover, one benefit from failure another fr...

Over the last few years a new type of global climate model (GCM) has emerged in which a cloud-resolving model (CRM) is embedded into each grid cell of a GCM. This new approach is frequently called a Multiscale Modeling Framework (MMF) or superparameterization. In this article we present a comparison of MMF output with radar observations from the NASA CloudSat mission, which uses a near nadir-po...

This paper presents a procedure for the design of a fuzzy logic controller for the garaging of a wheeled mobile robot, with non-holonomic constraints and discrete control signal levels. The design procedure is based on the virtual fuzzy magnet principle, which implies the definition of fictive points in the garage surroundings, and which, in an appropriate manner, by robot attraction, provides ...

Shortfall of electrical energy in Pakistan is a challenge adversely affecting its industrial output and social growth. As elsewhere, Pakistan derives its electrical energy from a number of conventional sources. The exhaustion of petroleum and conventional resources, the rising costs coupled with extremely adverse climatic effects are taking its toll especially on the under-developed countries l...

Predoctrinal deliberations about the employment of US armed forces, captured in Joint Doctrine Notes, remain critically understudied. Using comparative text analysis, this article identifies changes recent Note depictions military strategy. These risk distorting logic strategy, sacrificing means-ends integration to organizational impulse, and raising prospect future shortfalls strategic effecti...

This research measured the creative skills of 1000 Minnesota schoolchildren, compared it to performance on standardized achievement tests and examined the relationship between measured creativity and intelligence in our current school systems. Measured creativity has declined in school children since 1991 and this decline will have a greater impact on economic vitality than shortfalls in math o...

Developing Software Engineers at the C-130J Software Factory by Richard Conn, pp. 25–29. The education and training needs of avionics software engineers are diverse. Several shortfalls in conventional computer science and engineering education can result in mismatched expectations between new hires and their companies. Students must be prepared to work on teams, communicate, and understand the ...
