Many governments around the world are considering measures of happiness or subjective wellbeing as alternatives to gross domestic product (GDP) for the purpose of guiding economic policymaking. Compared to GDP, happiness measures promise to better capture the quality of life of a nation’s citizens and lead to policies that are more effective and equitable. However, there are a number of problem...

The neuMOS transistor is a comparatively new device developed in 1991 at Tohoku University, Japan, which is currently showing great promise in the direction of enhanced circuit functionality, particularly in Neural Network applications. In this paper we examine the possibilities of applying the inherent enhanced functionality of the neuMOS transistor to analogue and digital BIST. A novel concep...

In this paper, we apply continuous review (S-1, S) policy for inventory control in a three-echelon supply chain (SC) including r identical retailers, a central warehouse with limited storage space, and two independent manufacturing plants which offer two kinds of product to the customer. The warehouse of the model follows (M/M/1) queue model where customer demands follow a Poisson probabilit...

The performance of a product is often evaluated by several quality characteristics.  ptimizing the manufacturing process with respect to only one quality characteristic will not always lead to the optimum values for other characteristics. Hence, it would be desirable to improve the overall quality of a product by improving quality characteristics, which are considered to be important. The probl...

This study deals with a two-level supply chain consisting of one manufacturer and one retailer. We consider an integrated production inventory system where the manufacturer processes raw materials in order to deliver finished product with imperfect quality to the retailer, where number of defective product has a uniform distribution. The retailer receives product and conducts a 100% inspection....

Stripper columns are used for sweetening crude oil, and they must hold product hydrogen sulfide content as near the set points as possible in the faces of upsets. Since product    quality cannot be measured easily and economically online, the control of product quality is often achieved by maintaining a suitable tray temperature near its set point. Tray temperature control method, however, is n...

Pyrolysis of low density polyethylene (LDPE) by equilibrium fluid catalytic cracking (FCC) was studied in a stirred reactor under different process parameters. In this work, the effect of process parameters such as degradation temperature (420-510°C), catalyst/polymer ratio (0-60%), carrier gas type (H2, N2, ethylene, propylene, Ar and He), residence time and agitator speed (0-300 rpm) on the c...
