Products can be described by different numbers of attributes, but can the mere number of attributes presented across a choice set influence what type of options people choose? This article demonstrates that attribute numerosity tends to benefit certain types of options more than others and consequently has systematic effects on choice. Because attributes often serve as a heuristic cue for produ...

generally ordering policies are done by two methods, including fix order quantity (foq) and fix order period (fop). these methods are static and either the quantity of ordering or the procedure of ordering is fixing in throughout time horizon. in real environments, demand is varying in any period and may be considered as uncertainty. when demand is variable in any period, the traditional and st...

How can we detect traffic disturbances from international flight transportation logs, or changes to collaboration dynamics in academic networks? These problems be formulated as detecting anomalous change points a dynamic graph. Current solutions do not scale well large real world graphs, lack robustness amount of node additions / deletions and overlook attributes. To address these limitations, ...

The formation of multi-species feeding flocks (MSFFs) through visual recruitment is considered an important strategy for obtaining food in seabirds and its functionality has been ascribed to enhanced foraging efficiency. Its use has been demonstrated in much of the world's oceans and includes numerous species. However, there is scant information on the temporal stability of the composition and ...

Acetaminophen is one of the most important antipyretic and analgesic drugs. It has an excellent efficacy when it's used in therapeutic doses, but in unsafe doses it can be resulted in hepatotoxicity and permanent liver failure. Due to disparities that have been reported between the actual and stated concentration of acetaminophen tablets, we aimed to compare the actual quantity of 8 Iranian gen...

The definition of usability has evolved over time. Some of the proposed definitions have been general, and apply to all types of interactive systems. Others were tremendously influenced by the experience of those who proposed the definitions and the domain in which they practiced usability. The definitions, in general, seem to agree that the targeted users, the complexity of the task, the type ...

In this paper, we examine the incentives for firms to voluntarily disclose otherwise private information about quality attributes of differentiated products when those products have multiple attributes and consumers are heterogeneous in their tastes over these attributes. In particular, we focus on whether the so-called “unraveling result”—in equilibrium, firms fully disclose the quality of the...

dust accumulation capacity of ficus carica l. and psidium guajava l. was investigated from eight different sites of multan, pakistan.  leaves of both plants were used for analyzing biometric (leaf area, fresh and dry weights) and biochemical attributes (chlorophyll contents, carotenoids and ascorbic acid).  maximum dust accumulation was occurred in the plants growing near road sites, while, min...
