Abstract:
The paper lays out an ontological enquiry into the ways of ‘being of equipment’ as analysed by Heidegger and its role in understanding the design process. Equipments are things that make up our world. It is hard to imagine living without things because our existence is thingly textured. Heidegger’s analytics of equipment far exceeds the ontic sense of things. The argument is that there is a danger when designers limit themselves with the ontic understanding of equipment. Such an understanding coaxes us to believe in the half-baked truth about equipment- an isolated instance of a piece of artifact and leave us ignorant of the equipment's character as a part of an equipment structure. An ontological reflection on equipment brings forth its relational nature and can be rewarding in several ways in improving its design process.

Abstract:
It is well-known that reliability of equipment is the most important of all performance to all equipments. In order to make the equipments which include mechanical equipments, electrical equipments and so on work normally, reliability theory FMECA is applied in an aviation equipment to study its reliability and improve operational reliability of the product. Through its reliability mathematical model, average of operational time is predicted based on calculating failure probability of all electrical components. According to the process of FMECA, all kinds of the failure mode, reasons, effects and criticality of the products can be determined completely. By comparing these criticality data as shown, the paper analyses adopted method by that the contents, accents and operating process of maintenance may be instituted finally. FMECA-based method for reliability study of the equipment and the equipment maintenance perform well. The results indicate that application of FMECA method can analyze reliability in detail and improve operational reliability of the equipment. Therefore this will supply theoretical bases and concrete measures of maintenance of the products to improve operational reliability of products. FMECA can be feasible and effective for improving operational reliability of all equipments.

Abstract:
We propose a new model of equipment degradation. In it, the machine is subjected to random latent failures, the danger of which depends on the equipment condition and after each failure the intensity of the equipment's benefits decreases by a random amount. Equipment that brings negative benefits is subject to decommissioning. The model parameters are found based on known information about the average value and the coefficient of variation of the equipment lifetime. Market value of equipment is determined by discounting the flow of benefits from its future use. This allows us to find the dependence of the equipment’s market value on the benefits it brings. Assessing the market value of new equipment is usually not difficult, but it is much more difficult to do this for used equipment items. Appraisers are usually unable to estimate the value of the work performed by equipment, and when valuing a used equipment, they have to rely on its age. To do this, the market value of a similar new equipment is usually reduced by a depreciation factor or multiplied by Percent Good Factor (PGF, relative value), depending on the age of equipment being valued. However, equipment of the same age may be in different conditions and, therefore, have a different market value. Therefore, such PGFs, in fact, relate to the average equipment that has survived to the appropriate age. Appraisers determine them by formulas or tables that are usually not supported by proper justifications. The proposed model makes it possible to build the dependence of the average PGF on age and calculate the market value of the work performed by machines, even if such works are not traded on the market. It turns out that it is possible to take into account the influence of the utilization cost of the machine and inflation in the model. The results of experimental calculations performed using the model (with calibration parameters selected appropriately) are in good agreement with the market prices of some types of construction equipment.

Abstract:
Mstrado em Engenharia Eletrónica e Telecomunicações
As redes móveis estão em constante evolução. A geração atual (4G) de redes celulares de banda larga e representada pelo standard Long Term Evolution (LTE), definido pela 3rd Generation Partnership Project (3GPP). Existe uma elevada procura/uso da rede LTE, com um aumento exponencial do número de dispositivos móveis a requerer uma ligação à Internet de alto débito. Isto pode conduzir à sobrelotação do espetro, levando a que o sinal tenha que ser reforçado e a cobertura melhorada em locais específicos, tal como em grandes conferências, festivais e eventos desportivos. Por outro lado, seria uma vantagem importante se os utilizadores pudessem continuar a usar os seus equipamentos e terminais em situações onde o acesso a redes 4G é inexistente, tais como a bordo de um navio, eventos esporádicos em localizações remotas ou em cenários de catástrofe, em que as infraestruturas que permitem as telecomunicações foram danificadas e a cobertura temporária de rede pode ser decisiva em processos de salvamento. Assim sendo, existe uma motivação clara por trás do desenvolvimento de uma infraestrutura celular totalmente reconfigurável e que preencha as características mencionadas anteriormente. Uma possível abordagem consiste numa plataforma de rádio definido por software (SDR), de código aberto, que implementa o standard LTE e corre em processadores de uso geral (GPPs), tornando possível construir uma rede completa investindo somente em hardware - computadores e front-ends de radiofrequência (RF). Após comparação e análise de várias plataformas LTE de código aberto foi selecionado o OpenAirInterface (OAI) da EURECOM, que disponibiliza uma implementação compatível com a Release 8.6 da 3GPP (com parte das funcionalidades da Release 10). O principal objectivo desta dissertação é a implementação de um User Equipment (UE) flexível, usando plataformas SDR de código aberto que corram num computador de placa única (SBC) compacto e de baixa potência, integrado com um front-end de RF - Universal Software Radio Peripheral (USRP). A transmissão de dados em tempo real usando os modos de duplexagem Time Division Duplex (TDD) e Frequency Division Duplex (FDD) é suportada e a reconfiguração de certos parâmetros é permitida, nomeadamente a frequência portadora, a largura de banda e o número de Resource Blocks (RBs) usados. Além disso, é possível partilhar os dados móveis LTE com utilizadores que estejam próximos, semelhante ao que acontece com um hotspot de Wi-Fi. O processo de implementação é descrito, incluindo todos os passos necessários para o seu desenvolvimento, englobando o port do UE de um computador para um SBC. Finalmente, a performance da rede é analisada, discutindo os valores de débitos obtidos.
Mobile networks are constantly evolving. 4G is the current generation of broadband cellular network technology and is represented by the Long Term Evolution (LTE) standard, de ned by 3rd Generation Partnership Project (3GPP). There's a high demand for LTE at the moment, with the number of mobile devices requiring an high-speed Internet connection increasing exponentially. This may overcrowd the spectrum on the existing deployments and the signal needs to be reinforced and coverage improved in speci c sites, such as large conferences, festivals and sport events. On the other hand, it would be an important advantage if users could continue to use their equipment and terminals in situations where cellular networks aren't usually available, such as on board of a cruise ship, sporadic events in remote locations, or in catastrophe scenarios in which the telecommunication infrastructure was damaged and the rapid deployment of a temporary network can save lives. In all of these situations, the availability of exible and easily deployable cellular base stations and user terminals operating on standard or custom bands would be very desirable. Thus, there is a clear motivation for the development of a fully recon gurable cellular infrastructure solution that ful lls these requirements. A possible approach is an open-source, low-cost and low maintenance Software-De ned Radio (SDR) software platform that implements the LTE standard and runs on General Purpose Processors (GPPs), making it possible to build an entire network while only spending money on the hardware itself - computers and Radio-Frequency (RF) front-ends. After comparison and analysis of several open-source LTE SDR platforms, the EURECOM's OpenAirInterface (OAI) was chosen, providing a 3GPP standard-compliant implementation of Release 8.6 (with a subset of Release 10 functionalities). The main goal of this dissertation is the implementation of a exible opensource LTE User Equipment (UE) software radio platform on a compact and low-power Single Board Computer (SBC) device, integrated with an RF hardware front-end - Universal Software Radio Peripheral (USRP). It supports real-time Time Division Duplex (TDD) and Frequency Division Duplex (FDD) LTE modes and the recon guration of several parameters, namely the carrier frequency, bandwidth and the number of LTE Resource Blocks (RB) used. It can also share its LTE mobile data with nearby users, similarly to a Wi-Fi hotspot. The implementation is described through its several developing steps, including the porting of the UE from a regular computer to a SBC. The performance of the network is then analysed based on measured results of throughput.

ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada
For equipment and systems that are too expensive and too important to fail such as launch vehicles and spacecraft, the actual reliability is dominated by infant mortality failures that occur soon after dynamic environmental ATP that is used to eliminate the equipment that will fail prematurely. Premature equipment failures greatly increase risk getting to space and working in space, slowing down the growth of commercial space tourism. Premature equipment failures occur because during factory ATP, only equipment performance is measured and there is no relationship between equipment performance and equipment reliability. Accelerated aging was documented preceding GPS satellite atomic clock failures during the 10 years of the GPS Block I test and evaluation phase. Prognostic technology leverages the presence of accelerated aging to identify equipment that will fail. A prognostic analysis uses the same prognostic algorithms to convert equipment telemetry used to measure equipment performance to a time-to-failure (TTF) measurement, previously made using a probability distribution function. The equipment with accelerated aging that is present after ATP can be replaced, stopping infant mortality failures from occurring and producing equipment with 100% reliability. When all spacecraft and launch vehicle equipment that will fail prematurely are identified and replaced, satellite and launch vehicle reliability will be 100% and getting to space and working in space will be much safer.

Abstract:
The goal of the project is to evaluate a new setup for the company Iberobot Svenska AB, using HMI and PLC, for resistance spot welding equipment controller. The purpose of the controller is to control the weld process; weld power and time. One of the question raised is if this setup could be used as an RWE controller and thereby be able to re-place an old proprietary controller called TEC6000. A prototype is built compatible with current single phase RWE and literature study is conducted to answer this question.  The new setup is based on Beijer iX T7B Softmotion which includes an HMI and a PLC with EtherCAT support. EtherCAT input and output modules from Beckhoff are chosen because they can handle the speed required by the weld process. The controller is implemented using theory for RMS value, timing diagram and state diagram based on weld process. The prototype is revised three times. A zero crossing detector is implemented. A control element driver using opto-triac is implemented. Measurements using oscillo-scope are conducted which shows that the controller is able to start a weld, but zero crossing detection is unstable and further research into this and current regulation is needed before an end user product can be made.

Abstract:
The management of heavy construction equipment is a difficult task. Equipment managers are often called upon to make complex economic decisions involving the machines in their charge. These decisions include those concerning acquisitions, maintenance, repairs, rebuilds, replacements, and retirements. The equipment manager must also be able to forecast internal rental rates for their machinery. Repair and maintenance expenditures can have significant impacts on these economic decisions and forecasts. The purpose of this research was to identify a regression model that can adequately represent repair costs in terms of machine age in cumulative hours of use. The study was conducted using field data on 270 heavy construction machines from four different companies. Nineteen different linear and transformed non-linear models were evaluated. A second-order polynomial expression was selected as the best. It was demonstrated how this expression could be incorporated in the Cumulative Cost Model developed by Vorster where it can be used to identify optimum economic decisions. It was also demonstrated how equipment managers could form their own regression equations using standard spreadsheet and database software.

Abstract:
This paper reports the findings of the first stage of a study on how the efficiency of a centrifugal pump depends on the eccentricity of the impeller (rotor). The geometry of the pump is based on the ERCOFTAC centrifugal pump that has been used to validate computational fluid dynamics software with laboratory measurements. The pump is modelled using the CFD-code Comsol multi physics (tm) in order to get the pressure and velocity field. From the pressure and velocity field the efficiency and output power for the pump is calculated. The energy efficiency of the same pump with different static eccentricities is then compared, showing the effect of eccentricity To validate the CFD-model the velocity and pressure field for the pump is compared to results from another simulation of the same pump and an experiment. The comparison shows that the results are comparable and shows good agreement with experimental data. It is showed that the energy losses of the pump increase with increased static eccentricity of the impeller. The losses at 10% eccentricity are about 0.5% of the produced energy. The main contribution to the losses is the introduced asymmetry, eccentricity, of the pump, which causes an unsteady flow and also increases the total unbalance force on the rotor. It is further noted that rotor-stator interactions of the impeller and the stator blades have small influence on the energy losses. It is concluded that rotordynamic design can improve the energy efficiency of the process that the rotating equipment is involved in. Further research is suggested on whirling eccentric motion, experimental verification and more detailed simulation models.

Abstract:
Equipment quality is one of issues which Nuclear Power Plant owner concern most. The result of actual operation condition and lifetime after the equipment’s failure happens is the most important indicator to justify the equipment quality, but it’s too late to know it. It will be very useful if the quality can be deduced before the equipment’s installation and operation. The evaluation’s difficulty lies in several causations. For example, different equipments produced by different manufacturers and even they are produced by the same factory but the process is definitely different, including the design modification, material change, product reservation and quality non-conformance which almost happens in every manufacturing step. Through analyzing the manufacturing characters and using the evaluation theory, a model which describes the manufacturing quality is built. In this model, the manufacturing quality and final test are considered as 2 decisive factors to evaluate the Equipment quality, and under them, the more detail factors are resolved in the deeper level until it can be measured easily and accurately. In conclusion, the precise evaluation will benefit every field during the nuclear power project construction, and also in the operation Plant, including the project construction, nuclear plant safety operation, risk analysis and fault localization, etc.
