On decision making in tandem networks
… study the convergence of Bayesian learning in a tandem social network. Each agent receives a noisy signal about the underlying state of the world, and observes her predecessor's action before choosing her own. We characterize the conditions under which, as the network grows larger, agents' …

Tandem reaction sequences on a zirconocene template
… nuclear receptors: LRH-1 and SF-1. Equivalent tandem insertion of 1,1-dihalo-1-lithio species and lithium acetylides into saturated zirconacycles resulted in the synthesis of novel bicyclo[3.3.0]octanes, though in many cases limited by a ?-H elimination process.<br/>In the second area is …

Three terminal Si-Si:Ge monolitic tandem solar cells
… In this thesis a 3-terminal Si-Si:Ge monolithic tandem solar cell consisting of a top silicon solar cell and a bottom Si:Ge solar cell sharing a common base, which can take advantage of both the silicon solar cell and Si:Ge solar cells and overcome the current mismatch effect and photon losses …

Variable Precision Tandem Analog-to-Digital Converter (ADC)
… systems. The ADC uses a 4-bit Flash converter in tandem with SAR logic that has variable precision (0 to 11 bits). This allows the Tandem ADC to switch from a fast, imprecise converter to a slow, precise converter. The level of precision is determined by the input’s peak rate of change, optimized …

Simulation of tandem and Re-Entrant manufacturing lines
… such systems are the focus of this report. The Tandem and Re-Entrant systems allow for multiple part types to be sent through a single line of processing machines. The parts have different priorities which determine the order in which they are produced. The Re-Entrant system is unique because it …

Algorithms for Peptide Identification from Mixture Tandem Mass Spectra
… for the purpose of interpreting mixture tandem mass spectra, and our research work is mainly comprised of two components: de novo sequencing of mixture spectra and mixture spectra identification by database search. For the de novo sequencing approach, firstly we formulated the mixture …

Aspects of human relationship identification using short tandem repeats
Human short tandem repeat (STR) loci identification can be for linking material from a crime scene to an individual or linking two individuals. Paternity testing is one form of linkage where typically samples are tested between the mother, child and putative father (trio) and a probability (CPI) of …

Force modelling and energy optimization for subsoilers in tandem
… Africa, conventional subsoilers are used in a tandem configuration. The farmers believe that the use of subsoilers in this mode reduces the draft force per unit area tilled. This probably happens because the critical depth for the rear subsoiler is increased beyond its working depth of 600 mm. …

Advancing inorganic perovskite solar cells for application in tandem architectures
Silicon-perovskite tandem solar cells have remarkable power conversion efficiencies (PCEs) and can contribute to the rapid transition towards renewable energy sources. While inorganic perovskite solar cells show superior temperature stability as compared to organic-inorganic perovskite solar cells, …
