In this paper, the optimum shape of Tailor-Welded Blanks (TWB) is investigated. The optimization is performed for two different case studies. The first example is deep drawing of a TWB with dissimilar materials and uniform thicknesses and the next example is deep drawing of a TWB with similar materials and non-uniform thicknesses. The effect of blank optimization on the weld line movement is...

one of the main concerns of the mining industry is to determine ultimate pit limits. final pit is a collection of blocks, which can be removed with maximum profit while following restrictions on the slope of the mine’s walls. the size, location and final shape of an open-pit are very important in designing the location of waste dumps, stockpiles, processing plants, access roads and other surfac...

a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such...

Lymphomas of the gastrointestinal tract are usually secondary. Primary rectal lymphoma is very rare by virtue of its location. We present here a 60 years old lady diagnosed as primary rectal diffuse large B-cell Non-Hodgkin's lymphoma managed operatively. The optimum management of this entity is still much debated.

The optimum location and diameter, of an entry hole for an intramedullary nail, in the upper proximal femur, is investigated in this article. A comparative study for five different entry hole positions and seven different hole diameters at each position, has been pursued. The entry holes were located at the tip of the trochanter, at the superior, anterior and posterior parts of the lateral neck...

This paper considers the design of signature waveforms that optimize the total capacity of multiuser decoders for the QAM-synchronous Gaussian multiple-access channel under a Fractional Out-of-Band Power (FOBP) bandwidth constraint. In doing so, it imposes a hitherto unrecognized constraint that is relevant in wireless communication networks: the bandwidth must be independent of the location at...

Classic Kaposi's sarcoma (KS) is a disease with low mortality but high morbidity. The optimum treatment of KS depends upon several factors, including location of lesions, disease progression, severity of symptoms and patient preference. We report the long-term response to the use of intralesional doxorubicin to successfully treat a large cutaneous lesion of KS on a patient refractory to traditi...

In recent years, in Iran and other countries the power systems are going to move toward creating a competition structure for selling and buying electrical energy. These changes and the numerous advantages of DGs have made more incentives to use these kinds of generators than before. Therefore, it is necessary to study all aspects of DGs, such as size selection and optimal placement and impact o...
