This paper provides an alternate method of evaluating portfolio performance of stock pricing models. We apply Pitman Closeness Criterion to compare the accuracy of three popular pricing models. This comparison is used to assess which, if any, model outperforms the others. In assessing model performance over a long period of time, we find that the Fama-French three-factor model and the Carhart f...

Beam connections with reduced drilled section and slotted web have been presented after the Northridge earthquake (1994). Their new geometrical shapes have been resulted in weakening of beams and subsequently the bette rperformance of connections in the earthquakes. In this research, the advantages of both connections, mentioned above, have been studied in the Slotted Web Drilled Flange (SWDF) ...

Time Saving and energy consumption has become a vital issue that attracts the attention of researchers in Underwater Wireless Sensor Networks (UWSNs) fields. According to that, there is a strong need to improve MAC protocols performance in UWSNs, particularly enhancing the effectiveness of ALOHA Protocol. In this paper, a time-saving Aloha protocol with slotted carrier sense proposed which we c...

osting by E Abstract It is expected that many networks will be providing services at a time in near future and those will also produce different interfering signals for the current Slotted ALOHA based systems. A random packet destruction Denial of Service (DoS) attacking signal can shut down the Slotted ALOHA based networks easily. Therefore, to keep up the services of Slotted ALOHA based syste...

The token ring FDDI and the slotted bus DQDB are the two currently most important standards for high speed networks. Each of these networks has its own specific advantages and disadvantages, and its own specific type of load for which it petforms best. We propose a new network design, called Universal Channel Network (UCN). UCN is adaptive and can be made to behave either like a token ring, a s...

This paper describes a production-based asset pricing model. It is analogous to the standard consumption-based model, but it uses producers and production functions in the place of consumers and utility functions. The model ties stock returns to investment returns (marginal rates of transformation) which are inferred from investment data via a production function. The production-based model is ...

Fama (1970) defined an efficient market as one in which prices always ’fully reflect’ available information. This paper formalizes this definition and provides various characterizations relating to equilibrium models, profitable trading strategies, and equivalent martingale measures. These various characterizations facilitate new insights and theorems relating to efficient markets. In particula...

In F-logic and RIF, objects (frames) are de ned entirely separately from function and predicate applications. In POSL and RuleML, these fundamental notions are integrated by permitting applications with optional object identi ers and, orthogonally, arguments that are positional or slotted. The resulting positional-slotted, object-applicative (psoa) terms are given a novel formalization, reducin...
