bananas are climacteric fruits and controlling ripening is effective in reducing loss. this experiment studied the effect of packaging (plastic bag, edible wax and plastic bag, plastic bag and 2 or 4 g/kg potassium permanganate) over 5 weeks of cold storage on the quality and characteristics of cavendish cultivar bananas. the samples were removed from storage at 8, 16, 24, 32 and 40 days and fr...

Thin shell torispherical pressure vessel heads are known to exhibit complex elasticplastic deformation and buckling behaviour under static pressure. In pressure vessel Design by Analysis, the designer is required to assess both of these behaviour modes when specifying the allowable static load. The EN and ASME Boiler and Pressure Vessel Codes permit the use of inelastic analysis in design by an...

In this research, Performance-Based Plastic Design (PBPD) method has been modified according to the proposed method for considering Soil–Structure Interaction (SSI) effects. In the proposed modified method, based on the existing relationships and in order to maintain the simplicity of the PBPD design method, two important parameters have been modified in the PBPD design method. These two parame...

We present the approach of the IST FP6 project PLASTIC to the effective design and implementation of mobile services over B3G environments. The PLASTIC methodology for service design is based on transformations which are iteratively applied to various models used at specific design stages. Starting from a conceptual model, these models reflect characteristic properties of the mobile service und...

The coating of plastics for optical applications is intended to improve the mechanical durability of soft polymers and to serve an antireflection function. Usually a classic four-layer antireflection system is added on top of a single-layer hard coating. With needle optimization, an alternative coating design has been developed. The design is characterized by thin high-refractive-index layers t...

Although pallet, as a tool, yields signifi cant and widely recognized economic eff ects in production and distribution systems, it is still not fully utilized, indicating that it needs to be defi ned and developed as a specifi c product. Euro pallet product was designed using PRO/ENGINEER software system CAD module, as one of the most popular CAx systems, yielding a pallet of novel modular desi...

A global approximation method to optimize material architecture and cross-sectional area of new fiber reinforced plastic (FRP) composite beams is presented. The sections considered are intended for applications in short-span bridges. The beams are subjected to transverse loading, and the optimization constraints include deflection limit, material failure, and elastic buckling. Assuming a lamina...

Engineering can be seen as a balancing act in which several partially of fully conflicting needs have to be satisfied with one single solution. Concurrent engineering (CE) is a philosophy that aims for better products by improving the different design processes inside the whole development process. This is achieved by emphasizing holistic thinking. In this thesis the most relevant terms and def...
