在各种不同的电能转换方法中,有一种方法是利用压电来转换动能。通过使用压电振动或冲击可以用来收集电能,从而产生电能(天堂等,2000年)。它要求适当的电子器件的适用性,以有效地转换自给自足的能源供应系统。压电晶体可以在张力或压力的作用下发生机械变形,从而产生电荷。这些电荷也可以用压电元件电极上的可用电压来测量。为了确保以一种完美的方式实施能源收集解决方案,应该适当地考虑到同一解决方案的不同因素。为了调整能源的需求,能源使用者,能源转换器,能源储存和电子产品的使用。在过去的几年中,人们大量使用各种各样的能量收集装置来收集无用的能量。

Among different methods of conversion of electricity, one of the methods includes the conversion of kinetic energy by the means of piezoelectricity. Through the use of piezoelectricity vibrations or the shocks can be used to gather electrical energy leading to the generation of electric energy (Paradiso et al, 2000). It requires the applicability of suitable electronics for the efficient conversion of the self-sufficient energy supply system. Piezoelectric crystals can be mechanically deformed with the help of tension or pressure which leads to the generation of electrical charges. These electric charges can also be measured as the voltage available on the electrodes of the piezoelectric elements. In order to ensure that the energy harvesting solution should be implemented in a perfect manner, there should be the proper consideration of different factors for the same. In order to adjust the energy requirements, of the energy user, energy convertors, energy stores and electronics are used. In the past few years, there has been a vast use of the different kinds of energy harvesting devices for the purpose of harvesting the energy which is of no use.

The implementation of this kind of energy harvesting has been witnessing a huge growth as it can be used for the generation of power in different kinds of portable and importable units. Piezoelectric energy harvester can be used for the conversion of mechanical vibrations into electric energy in a very simpler structure. It is due to this feature that, the piezoelectric materials can be used for harvesting as a self-power source which is feasible for a wireless sensor system. It is one such form of electricity which is the representation of self-power source which can be used in electric systems. In this research, the emphasis is on the key ideas and performances which are related to the piezoelectric harvesting from vibration. Piezoelectricity is one such method which makes the use of pressure electricity and has the property related to the number of crystalline structures such as quartz, Rochelle salt etc. Further there has been the analysis of the processes which are implemented for obtaining the energy through the piezoelectricity. Different kinds of machines for the same have also been investigated. Piezoelectricity is one such method which gives the representation of pressure electricity.

项目目标是识别国际项目工程管理中风险的性质,并将这些风险划分为风险管理框架。国际风险管理是一个复杂的主题,因为风险管理问题可能在不同国家不同文化等基于一些类别。在这种情况下,本研究的目的不是解决多个问题,风险在国际项目管理但更普遍地关注他们。本研究具有探索性,为进一步的研究提供了范式。本研究采用了详细的文献综述。回顾了二级研究中发现的国际风险问题。通过文献综述确定了风险的主题和类别。文献综述是本研究进行批判性讨论的基础工作。本研究采用混合研究方法。定量和定性数据都得到了利用。关于风险管理的定性数据将是关于风险、风险的影响、增加风险发生的可能性和影响的国际项目工程管理问题等方面所确定的概念。因此建立了风险识别和分类框架。定量数据是指以数值数据的形式表示风险因素,并以实证研究的形式进行的研究。这将有助于使研究更加主观。所采用的数据收集方法是二次研究方法。

第二种研究方法已经被采用,因为这有助于识别不同的研究分析的主题。使用原始数据本可以使研究更具有时代性,但如果有时间,收集用于本主题的原始数据是不可行的。数据的收集是通过二手研究文章,学术期刊和商业组织的报告。这里使用案例研究方法对风险管理问题进行了比较批判性的讨论。本文考虑两家公司的国际项目工程管理。这两种案例研究方法使我们对国际风险有了比较的认识。多案例研究方法更适合本研究;然而,使用多案例研究方法会导致更浅显的讨论。只有使用这两种案例研究方法,才能进行深入的比较和批判性审查。根据讨论的结果,对国际项目工程管理中风险的分类提出了建议。本研究的意义在于揭示了地方项目管理风险与国际项目管理风险的差异。强调了风险的性质和理解这些风险类型的必要性。此外,本研究提出了一个可在国际项目工程管理案例情境中进一步测试的风险分类框架。

The project aim is to identify the nature of risks in international project engineering management and categorize these risks into a risk management framework. International risk management is a complex topic given that risk management issues could differ across different countries based on some categories such as culture etc. In this context the purpose of this research is not to tackle the multiple issues that come with risks in international project management but to focus on them in a more general manner. The research attempts to be exploratory as it offers a paradigm for further research to be conducted onto.The research makes use of a detailed literature review. The international risks issues that are identified in secondary research are reviewed. The themes and categories of risk are identified by using the literature review. The literature review forms the base work on which the research critical discussions would be conducted.The research makes used of mixed research method. Both quantitative and qualitative data are made use of. Qualitative data on risk management would be the concepts identified with respect to risks, the effect of risks, international project engineering management issues that increases the likelihood and impact of risk occurrence and more. A risk identifying and categorizing framework is hence established. Quantitative data collected is on the research studies where risks factors are expressed in the form of numerical data and as empirical studies. This would help to make the research study more subjective. The data collection method used is the secondary research method.

The secondary research method has been employed as this is useful to identify the different research analysis on the topic. The use of primary data could have made the research more current, but the collection of primary data to be used for this topic would not have been feasible given the time. The data is collected by means of secondary research articles, scholarly journals and reports of the business organizations.The case study approach has been used here to present a comparative critical discussion on risk management issues. The international project engineering management of two companies are considered here. The two case study approach enables a more comparative understanding on international risks. The multiple case study approach would have suited this research better; however use of multiple case study approach would have resulted in a shallower discussion. An in-depth comparative and critical review is possible only with the two case study approach.Using the results of discussions, recommendations are made for the categorizing of the risks in international project engineering management. The significance of this research is that it brings to forefront the differences between local project management risks and international project management risks. The nature of risks and the need to understand these types of risks are highlighted. Furthermore, the research presents a categorized framework of risks that could be tested out further in international project engineering management case scenarios.
