The Impact

The ZEUS (Zero Emission Ultimate Ship), developed in the framework of the national research project TecBia conducted by Fincantieri and co-founded by Italian Ministry of Economic Development, is a 25m length vessel characterized by a zero-emissions propulsion system. The on-board power generation is provided by 4 PEM Fuel Cell modules (140 kW power installation) fed by hydrogen stored into 48 Metal Hydride tanks (MH). PEMFC and MH thermal systems are coupled to recover the heat produced by PEMFC and to feed the endothermic dissociation reactions of hydrogen from MHs. This paper provides a Matlab-Simulink model to simulate the dynamic behaviour of the PEMFC power generation system and the thermal coupling with MH racks installed onboard. Three typical operative profiles are simulated to verify the thermal management control system and the impact of transient conditions on the propulsion plant. Furthermore, the effects of the major exogenous parameters are investigated. Results verify that thermal coupling between the two systems is guaranteed; however, an excessive load increase can lead the stacks to operate under non-optimal conditions for significant periods of time. The effect of exogenous parameters has been verified to be negligible and does not significantly affect the control system.

Levers Of Control

This paper intends to demonstrate the relationships between the management control system (MCS) as a package elements with organizational performance. Many studies conducted and investigated the impact of the management control system (levers of control) and organizational performance and ignore the elements of MCS as a package. Pakistan textile industry faces a lot of issues regarding MCS as packages elements and due to these issue organizational performance reduced. Therefore, current study portray a framework that consists of some vital elements of control adopted from Malmi and Brown (2008) MCS as a package like planning control, cybernetic controls, rewards and compensation controls, administrative controls, and cultural controls which if empirically investigated would demonstrate the extent of by in Pakistan textile industry and how these controls generate better organizational performance. This suggests that the need for more explanation of Pakistani textile industry managers on the need to adopt better MCS practices as these practices lead to better organizational performance. Although the current paper is conceptual in nature thus, needs an empirical study to address in the light of resource-based view theory.

The Impact

The system of space monitoring (SM) is of great importance, as a means of ensuring environmental safety. This system is based on remote sensing. The structure of SM is a distributed system. This system comprises independent data storage, system control, system of dynamic ratings, capacity and forecasting, control system, information system (IS) processing of monitoring data. As IS it is necessary to choose a geographic information system (GIS). IS monitoring refers to the problem-oriented system. These information systems include specialized databases models. All monitoring systems use sets of models, which allow building complex enterprise models. The peculiarity of the SM is the need to coordinate support of this monitoring and rate of the GIS capacity. Production Manager's decision is the impact on the object of monitoring. Results management and environmental data are received at the monitoring subsystem. Integration of SM and GIS monitoring has led to the creation of geoinformation space monitor (GISM). The operation of the system GISM is designed to provide a guaranteed result taking into account the capacity. Basis – the decision of the decision makers (DM). Therefore, an independent scientific and practical interest is the adequate mathematical model of DM.

Plant Design

This study is focused on the possible application of hydrogen-fed PEM fuel cells on board ships. For this purpose, a test plant including a 100 kW generator suitable for marine application and a power converter including a supercapacitor-based energy storage system has been designed, built and experimentally characterised. The plant design integrates standard industrial components suitable for marine applications that include the technologies with the highest degree of maturity currently available on the market. Fuel Cell generator and power converter have been specifically designed by manufacturers to fit the specific plant needs. The experimental characterisation of the plant has been focused on the evaluation of the efficiency of the single components and of the overall system. Results shows a PEM fuel cell efficiency of 48% (when all auxiliaries are included) and an overall plant efficiency, including power conditioning, of about 45%. From load variation response tests, the fuel cell response time was maximum 2 seconds without supercapacitors and increased up to 20 seconds with supercapacitors connected, reducing the stress on the fuel cell generator. Experimental results confirm that PEM fuel cells, when supported by a suitably sized energy storage system, represent a viable technical solution for zero-emission power generation on board ships.

The Impact

With globalisation, there has been an intensification of investments by foreign groups in sectors strategic to their country of origin, such as some minerals. It is, therefore, crucial for a parent company to implement specific controls in its management control systems. In these circumstances, this study aims to determine the degree of control exercised by the parent company over a subsidiary in cultural and organisational dimensions. In addition, other exogenous factors (entities and external factors) influence this system. The results obtained showed that the parent company had an influence on the Management Control System (MCS) of the subsidiary and changed the way control was exercised there, but was unable to deal with macroeconomic instability, environmental and strategic uncertainty, and, consequently, the management risk involved in the extractive activity; in this case, for this subsidiary to operate a seam mine and not be aware of it since it is essentially a commercial, economic group. In addition to these effects on the organisational dimension and the cultural dimension, the shareholders were unable to integrate the subsidiary’s organisational and local culture, which generated some dynamic tension with the expatriate. In addition to the theoretical framework used, it was confirmed that the Flamholtz model is passive to implement in industries in general, particularly in the extractive industry. Finally, some final considerations were made about the management control system, in which the argument is reinforced that there must be empathy between the local staff and the expatriate, as a representative of the shareholders, in order for this system to be a vehicle for the effective transfer of knowledge between both parties, as well as to be supported by open innovation.

Personnel Control

This study aims to determine the impact of permissiveness in the management control system. Management control system cannot be implemented because of permissiveness that gives looseness in management control system. Problems occur are in the form of attendance and attendance of employees, punishment is less applied with firm, tolerance in recruit employees. Writing this thesis is included in applied research where the author hopes with the writing of thisthesis can assist in providing recommendations and suggestions related to management control system in Sinar Motor. The research method used is by interview, observation and data analysis. At this writing will be discussed about the management system of the company's management Sinar Motor include action control, result control, personnel control and cultural control. However, the management control system has not been able to perform well due to permissive generated from the nature of the owner who did not bear, pity and trust. To minimize the problem, the authors provide recommendations in the form of a limitation of tolerance that can be done by the owner for each problem. With some recommendations are expected to improve management control systemUD Sinar Motor.
