large sums of fruits are annually wasted due to mechanical damage and bruise inflicted upon them during harvesting, handling, storage and packaging. the research which has been done to analyze the mentioned processes mostly used practical operational techniques with the results being applicable in certain defined conditions. the aim of this research was to develop computer models for an optimiz...

To improve the primary frequency response in future low-inertia hybrid power system a fuzzylogic based frequency controller (FFC) for wind farms augmented with energy storage systems(wind-storage system) and intelligent PV farms for the frequency stabilization is proposed inthis paper. Using system frequency deviations the proposed controller provides bidirectionalreal p...

The world is being transformed as connected devices and equipment, embedded with sensors and software, communicate with one another and the cloud. The data generated by such intelligent technology can be analyzed to extract valuable information about the physical world, such as when an auto part is likely to fail, or how to make a wind turbine run more efficiently. Commonly referred to as the I...

To support future interactive information delivery services there is a need to balance individual interactivity with the desire to maximize the number of supported sessions. Currently, few techniques have demonstrated the ability to renegotiate and scale service parameters per session in progress as required to adapt to differing terminal equipment characteristics and network congestion. This p...

Tests show that ethylene oxide penetrates and can sterilise long narrow tubes in a hospital ethylene oxide steriliser. Residual ethylene oxide levels in plastic tubing after sterilisation have been estimated. Although initially the levels were very high, storage for four days at room temperature reduced them to a safe level. If adequate controls of the sterilising process and storage are carrie...

physical properties are often required for designing post harvest handling and processing equipment for agricultural products. persimmon (khormandy cultivar) is rich in vitamin a, calcium, potassium, tannic acid and antioxidant phenolic compounds. in this study changes in the physical properties of persimmon fruit during storage were studied. properties such as fruit dimensions, mass, geometric...

In order to solve the problem of aviation equipment system maintenance, it is very difficult judge faulty finished product according fault phenomenon, author proposes a data mining-based prediction model for failure products. The takes historical record as input, clusters large number descriptions through text clustering obtain phenomenon clusters, and establishes many-to-many relationship betw...

A thermal energy storage (TES) equipment utilizing phase change material (PCM) was designed and built. The PCM is sealed inside metal tubes and exchanges heat with process fluid flowing outside. The storage capacity characteristics of the system was analyzed based on date covering the inlet and outlet temperatures of the process fluid, volumetric flow rate of the process fluid, and temperature ...

The present paper is confined to the discussion of technical grade paraffin waxes as phase change material (PCM) for cool storage and the cool storage systems capital cost investment. The objective of this study is to determine the potential for using cool storage systems. The thermal properties of technical grade paraffin waxes as PCM are investigated, and static and dynamic cool storage proce...
