grapes are among the world most planted horticultural crops. since the last century, attempts have been made to improve the quality of grapes in the world. meanwhile, the necessity of having knowledge about the history of progenies families led to the link between genealogy and breeding. considering some previous mislabeling, in order to find out the accuracy of the controlled crosses as well a...

The prevailing labor market models assume that minimum wages do not affect the labor supply schedule. We challenge this view in this paper by showing experimentally that minimum wages have significant and lasting effects on subjects’ reservation wages. The temporary introduction of a minimum wage leads to a rise in subjects’ reservation wages which persists even after the minimum wage has been ...

Paper aims This study presents several business analytics tools that allow improving the tactical planning of collection process for a Colombian solid-waste management company. Originality The extant literature operations research/analytics applied to these systems focuses on facility location or vehicle routing. Tactical decisions are seldom studied in devoted waste systems. By contrast, focus...

The concept of hypo-Euclidean norm for an n−tuple of vectors in inner product spaces is introduced. Its fundamental properties are established. Upper bounds via the BoasBellman [1]-[3] and Bombieri [2] type inequalities are provided. Applications for n−tuples of bounded linear operators defined on Hilbert spaces are also given.

This panel discusses the decline in the information systems field and argues that an emphasis on the major transformations enabled by technology will help rekindle interest and excitement about the technology. We will discuss a documentary on IT-enabled transformations that the Smith School at the University of Maryland is co-producing with Maryland Public Television for viewing on public telev...

Bike sharing systems consist of a fleet of bikes placed in a network of docking stations. These bikes can then be rented and returned to any of the docking stations after usage. Predicting unrealized bike demand at locations currently without bike stations is important for effectively designing and expanding bike sharing systems. We predict pairwise bike demand for New York City’s Citi Bike sys...

The present paper is a five-week content analysis of crime stories reported on television news. The sample consists of three nightly newscasts available on a rural, midwestern cable system. Included are nightly newscasts from a national network, a big city television station, and a small town channel. Findings from this exploratory study show that these three sources of television news differ s...

In large multiple-input multiple-output (MIMO) systems, we offer a new access strategy for crowd situations. Crowd situations include high number users who have intermittent patterns, making orthogonal scheduling impossible. this paper, the work is driven by massive MIMO problem at crowded environment. The pilot contamination dependent on protocol assumptions observed in system. We investigate ...

We are interested in the problem of determining size a fleet robots able to perform transport operations logistics warehouse. The divided into several phases: loading, loaded travel, unloading and empty travel. first determine minimum number needed set homogeneous loads from point A B over determined time interval. For same robots, many assignments exist. assignment that minimizes makespan, whi...

To enhance the system throughput and to extend coverage of IEEE 802.16 networks, relay stations can be implemented. If a user station is attached to the base station (BS) through several relays stations (RS), a multi-hop communication occurs. To enable multi-hop communication, the IEEE 802.16j standard proposes two approaches how RSs can be implemented into the network. The first approach group...
