Abstract:

Research on unit load stability aids manufacturing facilities in selecting the most efficient load stabilizer when shipping their products to market. This studyâ s objective was to compare the performance a variety of different commonly used load stabilizers to stretch hooding. Stretch hooding is a method of load stabilization in which a tubular film is heat sealed at the top, stretched by four mechanical arms to a desired width, pulled down over the unit load. The film is slowly released as the arms descend, and is released under the pallet. 400ga stretch hooding, 80ga and 63ga stretch w

Abstract:

Sustainability is one of the most critical issues in today's packaging and supply chain industries. With the increase of environmental concerns, there has been a tremendous effort to improve packaging sustainability. However, most of these works have focused on individual packaging components rather than an integrated unit load. In global supply chains, three levels of packaging components (primary, secondary, and tertiary) are commonly assembled in the unit load form to facilitate efficient and economical storage and transport of goods to customers. Unit loads is important to improved, packag

Abstract:

The occupant plays an important role in residential energy consumption, and likewise, a critical part in energy conservation. Studies have shown that energy consumption in similar houses can vary significantly due to the occupant’s behaviour and household characteristics. Nevertheless, very few studies have focused on identifying the occupant driven parameters responsible for energy variations or on quantifying their impact. This study analyzes the impact of the occupant’s preferences of temperature settings, the number of thermostats used, the door operations, the use of window curtains, and

The construction equipment industry is developing at a fast pace, increasing the expectation on the next-generation machines.

One of the most important parts of the wheel loader is the loading unit. This is traditionally designed using highly experienced engineers and CAD software.

The optimization of pallet design in today’s competitive supply chain is imperative to reduce costs and improve sustainability. With over two billion pallets in circulation in the United States, most packaged products are handled using unit loads and the interactions between the unit load components are not being considered in the pallet design process. This study aims to investigate the effect of the interlocking of layers and the pallet stacking patterns on pallet bending.

The global supply chain has been built on the material handling capabilities provided by the use of pallets and corrugated boxes. Current pallet design methodologies frequently underestimate the load carrying capacity of pallets by assuming they will only carry uniformly distributed, flexible payloads. But, by considering the effect of various payload characteristics and their interactions during the pallet design process, the structure of pallets can be optimized. This, in turn, will reduce the material consumption required to support the pallet industry. In order to understand the mechanica

There are currently no tools available for a packaging engineer to make a scientific decision on how one stretch film performs against another without applying the film. The system for stretch wrap comparison is mostly based on trial and error which can lead to a significant loss of product when testing a new film or shipping a new product for the first time.

Currently, pallets are designed assuming that the load is distributed evenly on the top of the pallet. When pallets are loaded with packages such as corrugated boxes or returnable plastic containers, due to their physical shape, packages, are not capable of deforming freely with the pallet and a bridging phenomenon occurs. During this load bridging phenomenon, a portion of the vertical forces are redistributed as horizontal forces which causes the redistribution of the vertical compression stresses on the pallet towards the support. As a result, the deflection of the pallet can decrease and th

During unitized shipment, the components of unit loads are interacting with each other.

This asymmetrical support could significantly affect the strength of the corrugated boxes, and it depends on the top deck stiffness of the pallet.

Abstract:

Sri Lanka is an island at the Indian Ocean with 65234 km2 and it has a power demand of 2000 MW. The hydro power was the main power source before year 2000, after maximum usage of hydro power Sri Lanka installed fossil fuel power plant to achieve the demand. Then the electricity price gradually increased due to higher increment of fuel price. As the solution for this higher price of electricity the government has to go to new profitable power source the coal power. Finally year 2011 Puttalam coal power plant 300 MW x 1 was installed with the hope of providing the low cost reliable energy supply

Abstract:

This master's thesis summarizes theory on how to perform data load onto on-board computers of aircrafts. Specifically, how automated data load of Honeywell's Aspire 400 satellite data unit is done. First part of the text describes requirements and possible ways of the data load process, including standards that are applicable to this topic in the aeronautical industry. The second part describes the implementation of the data load process on the aforementioned unit.

Abstract:

As the further development of single-core architectures faces seemingly insurmountable physical and technological limitations, computer designers have turned their attention to alternative approaches. One such promising alternative is the use of several smaller cores working in unison as a programmable hardware accelerator. It is clear that the vast – and, as yet, largely untapped – potential of hardware accelerators is coming to the forefront of computer architecture. There are many challenges that must be addressed for the programmable hardware accelerator to be realized in practice. In this

Les semi-conducteurs cristaux liquides et les matériaux à faible gap sont deux familles de matériaux intéressants pour des applications dans le domaine de l’optoélectronique. Ils peuvent être utilisés dans de nombreux dispositifs électroniques différents tels que les cellules solaires organiques (OPV), les diodes électroluminescentes organiques (OLED) et les transistors organiques à effet de champ (OFET). Dans ce travail, nous nous sommes concentrés sur la conception et la synthèse de nouveaux matériaux semi-conducteurs constitués d’architectures donneur / accepteur qui présentent soit des pro

Abstract:

Žemės ūkio paskirties traktorių pagrindinis tikslas yra atlikti tempimo darbus esant įvairioms sąlygoms ir skirtingiems kelio paviršiams. Traukos jėga priklauso nuo traktoriaus eksploatacinių rodiklių, tokių kaip: ratų sukibimas su paviršiumi ir jų buksavimo dydis, traktoriaus išvystoma traukos galia ir t.t. Visi šie rodikliai kinta kintant traktoriaus bendrajai masei tuo pačiu ir vertikaliosioms apkrovoms veikiančioms kiekvieną iš traktoriaus ratų. Todėl atliekant įvairius žemės ūkio darbus, reikia tinkamai įvertinti traktorių veikiančias statines bei dinamines apkrovas. Magistrinio darbo tem

Abstract:

Il lavoro di tesi magistrale è stato incentrato sullo sviluppo, la realizzazione e la caratterizzazione metrologica di una Remote Measurement Unit (RMU) per Smart Grids basata su microcontrollore. Lo scopo della RMU è quello di acquisire le grandezze elettriche presenti in un nodo della rete di distribuzione, elaborarle e fornirle ad un’unità centrale adibita al controllo della rete, dove, sulla base delle informazioni provenienti da tutte le postazioni di misura, vengono prese le decisioni per la gestione ottimale del sistema elettrico. La RMU riceve in ingresso sei segnali, condizionati e

Abstract:

Recent large-scale blackouts revealed that power systems around the world are far from the stability and reliability requirement as they suppose to be. The post-event analysis clarifies that one major reason of the interconnection blackout is lack of wide area information. Frequency dynamics is one of the most important parameters of an electrical power system. In order to understand power system dynamics effectively, accurately measured wide-area frequency is needed. The idea of building an Internet based real-time GPS synchronized wide area Frequency Monitoring Network (FNET) was proposed to
