This paper aims at positioning producer cooperatives within the Transaction Cost Economics theory, one of the most cited and prolific theories on management studies. To accomplish this goal, I will answer the questions what is a cooperative, which transactions producer cooperatives regulate, under which market conditions they operate, and where are the boundaries for such organizations. This pa...

We derive bounds on the ratios of deadweight loss and consumer surplus to producer surplus under Cournot competition. To do so, we introduce a parameterization of the degree of curvature of market demand using the parallel concepts of ρ-concavity and ρ-convexity. The ”more concave” is demand, the larger the share of producer surplus in overall surplus, the smaller is consumer surplus relative t...

In this paper we propose to use feedback control to automatically allocate disk bandwidth in order to match the rate of disk I/O to the real-rate [13] needs of applications. We describe a model for adaptive resource management based on measuring the relative progress of stages in a producer-consumer pipeline. We show how to use prefetching to transform a passive disk into an active data produce...

In this paper, we evaluate the stability of a plan solution at the task level and argue that it is important for task structure based multi-agent replanning. With a plan solution represented by a TÆMS (Task Analysis, Environment Modeling and Simulation) task structure, we define new metrics of the stability of a TÆMS solution and use it to rank and recommend plan candidates. We preliminarily ev...

Abstract The present experimental study aims to examine the combustion and emission characteristics of a single cylinder four stroke direct injection diesel engine operated in dual fuel mode using dairy scum oil methyl ester (DiSOME) its blend (B20)—producer gas combination with without addition hydrogen. DiSOME/B20-producer hydrogen exhibited inferior performance increased hydrocarbon carbon m...

Farming plays an important role in the survival of human civilization. As our forefathers have taught us, agriculture has a long-evolutionary history that one can learn from. The Internet Things (IoT) is used to improve crop yields. IoT enables internet-connected equipment with sensing devices exchange information others. sensor land collect data remotely and send it producer timely manner. Amo...

Climate change and geopolitics have led to the conception of plans for reducing greenhouse gas emissions improving sustainability existing fossil-based energy systems. In this respect, district heating has been identified as an indispensable player its potential integrate seamlessly environmentally-friendly heat sources. To improve efficiency these systems, optimal operation schemes can be devi...

Resource-constrained project scheduling problems are one of the most studied scheduling problem, and constraint programming with nogood learning provides the state-of-the-art solving technology for them, at least when the aim is minimizing makespan. In this paper we examine the closely related problem of scheduling producers and consumers of discrete resources and reservoirs. Producer/consumer ...

Adenovirus (Ad) vectors, in particular those of the serotype 5, are highly attractive for a wide range of gene therapy, vaccine and virotherapy applications (as discussed in further detail in this issue). Wild type Ad5 virus can replicate in numerous tissue types but to use Ad vectors for therapeutic purposes the viral genome requires modification. In particular, if the viral genome is modified...
