the packaging industry by promoting the production capability has an important role in the development of different economic sectors. empowerment of packaging industry increases the competitiveness of other economic sectors. on the other hand, packaging industry has an important role in increasing the national income and employment. these factors cause the governments to pay special attention t...

Six different composite packaging materials were tested with the trades’ practice of polythene bags in storing smoked catfish for a period of six months. The thickness of the packaging materials ranges from 0.23 to 046 mm with water and oil absorption rates of the packaging materials varies from 0.23 to 10.00 and 0.28 to 10.857 glcm2/mm respectively. The impact resistance weight also varies fro...

We are the rst to develop SPICE compatible circuit model for reluctance K It can be combined with any reluctance based extraction method to perform RLC simulation directly without the need of inverting reluctance matrix back into inductance domain or modifying conventional simulator To build symmetrical reluctance matrix we also proposed blocked K method based on group concept to cover more mag...

We propose here a fully Spice-oriented design algorithm of op-amps for attaining the maximum gains under low power consumptions and assigned slew-rates. Our optimization algorithm is based on a well-known steepest descent method combining with nonlinear programming. The algorithm is realized by equivalent RC circuits with ABMs (analog behavior models) of Spice. The gradient direction is decided...

The purpose of food packaging is to preserve the quality and safety of the food it contains from the time of manufacture to the time it is used by the consumer. Recently, the demand for safe and high quality foods, as well as changes in consumer preferences have led to the development of innovative and novel approaches in food packaging technology. One such development is the active food packag...

with the development of beverage industry and expansion of the markets , packaging of these products has also come out of its traditional form and intelligent packaging has been applied gradually. different types of smart packaging are used in the beverage industry such as gas release packaging which by gas production causes a good texture and is used in order to create a creamy milk coffee. in...

The field of optimisation is still not appropriately covered in modern computer programs for circuit analysis as SPICE. It was originally developed at the University of California at Berkeley. The last official release of SPICE 3f4 was published in 1992. It has numerous bugs, mainly memory leaks. In order to implement optimisation methods most bugs were tracked down and fixed. Several well-know...

With single-electron tunneling (SET) technology it is possible to build electronic circuits with extreme low power properties. These SET circuits must therefore operate in the single electronics (current) regime. To simulate SET circuits in this regime, a SPICE model has been written. In contrast to the prescriptions in the so-called Orthodox theory of single-electronics, the SPICE model explor...

BACKGROUND Measurement of dietary intake of spices is gaining significance because of recognition of their health promoting benefits as well as its use for risk assessment of contaminant exposures. Estimating intake of spices at the individual level, presents several challenges since various spices are used as an integrated part of a prepared food and consumed in amounts much smaller than other...
