This article contributes to the debate of missing money (e.g. Joskow(2007)) which has seriously questioned the desirability of caps on scarcity prices in markets with fluctuating demand by emphasizing their potentially negative impact on firms investment decisions in the long run. A prominent example are recently liberalized electricity markets, where competition authorities have imposed caps i...

Improved stream crossings are needed to reduce construction and maintenance costs and reduce the environmental impacts from low-volume forest roads and skid trails. New designs of timber bridges are cost-effective alternatives for portable stream crossing structures. This paper discusses design criteria for portable timber bridges and presents one design for a portable, longitudinal glued-lamin...

Static pile load test to failure is the ultimate procedure available to examine the capacity and integrity of deep foundations. Being expensive and time consuming, the procedure is often substituted for the application of a load to a certain factor (most often two) times the contemplated design load. In fact, only a proof test is carried out while the ultimate capacity and actual factors of saf...

estimate of sediment load is required in a wide spectrum of water resources engineering problems. the nonlinear nature of suspended sediment load series necessitates the utilization of nonlinear methods to simulate the suspended sediment load. in this study artificial neural networks (anns) are employed to estimate daily suspended sediment load. two different ann algorithms, multi layer percept...

Load Testing helps to capture performance at different load levels. It is naïve to assume that application performance at a certain load level may be in the same band that the load testing has pointed out. By introducing small spike for short duration we observed that applications either show resiliency, graceful degradation and recovery or total crash even after the spike has subsided. This be...

measurement of the values of forces in tractor arms is of great importance due to draft of agricultural equipment. these values can be used for testing and evaluation of the agricultural machinery, selection of suitable tractor, etc. the tools which are used for measurement of the forces are called dynamometer. the main objective of the present study was to design and evaluate a load cell for i...
