Software engineering is a new engineering discipline. Our understanding of what constitutes good software engineering skills is limited and must improve. Using the Personal Software Process (PSP), as a context for conducting empirical research in software engineering, is one way of improving our understanding. This paper examines the defect removal situation for a group of students within the c...

Field experiments were conducted on-farm in the forest zone of Ghana to determine the effects of stubble mulch (in-situ residues from Mucuna pruriens var utilis or natural grass fallow) and method of land preparation on the yield of dry season tomato (Lycopersicon esculentum). Land preparation methods studied were slash burn and ridge; ridge and mulching with the existing residue; and zero till...

In the hotel sector, yield management traditionally balances a supply of perishable room nights against demand by manipulating price and time of consumption. While widely accepted, Internetbased distribution channels with different cost structures complicate the process. Hotels must not only manipulate price in response to supply and demand, but must also choose which portfolio of distribution ...

Improving irrigation water management is becoming important to produce a profitable crop in South Texas as the water supplies shrink. This study was conducted to investigate grain yield responses of corn (Zea mays) under irrigation management based on crop evapotranspiration (ETC) as well as a possibility to monitor plant water deficiencies using some of physiological and environmental factors....

Can airline Yield Management strategies be used to generate additional revenue from spare capacity in telecom networks? Pundits believe “yes”, based on several analogies between the industries such as, for instance, perishable inventory and negligible marginal cost of usage. However, no one has yet described how, one of the chief difficulties being the vastly different nature of airlines produc...

The paper presents a yield optimizing scheduling system (YOSS) in a decentralized supply chain management (DSCM) environment. For this purpose we employ a DSCM scenario in which each supplier, provides system parts by order of one or more customers. The supplier tries to optimize its return by searching the optimal schedule for the single machine he uses to manufacture the requested products. T...

In this paper we study strategies for better utilizing the network capacity of Internet Service Providers (ISPs) when they are faced with stochastic and dynamic arrivals and departures of customers attempting to log-on or log-off, respectively. We propose a method in which, depending on the number of modems available, and the arrival and departure rates of different classes of customers, a deci...

by application of climatic zoning methods, it is possible to study different agricultural aspects and then with harmony this aspects, determined similar states in a zone. today, simulation models are widely used around the world in agricultural research and education and cropland management. due to the vast extent of the agricultural activities in iran, application of such models seems to be qu...

A field study was conducted on hummocky terrain at the Manitoba Zero Tillage Association Research Farm near Brandon, Manitoba, Canada to determine the variability of crop yield as related to landscape position, soil properties, weed populations and plant disease. This information was used to develop a method for delineation of management units related to precision farming. Variable-rate fertili...

this experiment was conducted for three consecutive years from 2000 to 2002 to evaluate the effects of integrated weed management on weeds of alfalfa at the safi abad agricultural research farm of dezful. the experimental design was a randomized complete block with strip-split plot arrangement of treatments. herbicide treatment was as horizontal factor at five levels which in 2000, consisted of...
