This work deals with the reduction of aircraft interior noise using active sidewall panels (linings). Research work done in the past showed that considerable reductions of the sound pressure level (SPL) in the cabin are possible using structural actuators mounted on the lining and error microphones distributed in front of the linings. However, microphones are undesirable for error sensing because they are not suitable for the realisation of an integrated and autonomous active lining (smart lining module). Therefore, the goal of the present work is the replacement of the microphones by structural sensors. Using the structural sensors as remote sensors in combination with an acoustic filter, virtual microphones can be defined. The present study relies on experimental data of a double-walled fuselage system which is mounted in a sound transmission loss facility. Simulation results based on measured time data and identified frequency response functions are provided. Different configurations of virtual microphones are investigated regarding the SPL reduction and the induced vibration of the lining panel.

... In view of the number of organizations annually participating in these expeditions, the Argentine Government decided to establish one central organization to be responsible for the scientific work done by Argentina in the Antarctic. In addition, this organization was to be the common repository for information gathered on previous Argentine expeditions, as well as for that of future endeavours. The Instituto Antartico Argentino was therefore established in Buenos Aires. It is a scientific and technical organization whose mission is to study the nature of the antarctic region. From its inception, it has steadily grown to occupy a prominent position in antarctic affairs and become the leading organization influential in all Argentine antarctic problems. By Presidential Order the organization entitled "Instituto Antartico Argentino 'Coronel Hernan Pujato' " was established on 17 April 1951 under the administration of the Minister of Technical Affairs. The name honored Coronel Hernan Pujato, who commanded the first Argentine Army antarctic expedition. He became the Institute's first Director. With the preparations for the International Geophysical Year underway, the Institute's activities expanded and Captain Rodolfo N. Panzarini, now a retired rear admiral, was named Director. He still retains this position and is the main driving force behind the organization (see Fig. 1). At the time of his nomination, the organization officially took the name "Instituto Antartico Argentino" (I.A.A.). The Institute is an in-house polar organization, containing in one building the entire administrative staff, scientists, technicians, laboratories, shops, and equipment storage facilities necessary to carry out scientific investigations in the Antarctic. There is an advantage in keeping under one roof the majority of persons with an active interest in antarctic work so that they can confer easily with one another, exchange data, and have easy access to a polar library. Such a closely knit organization constitutes a potentially powerful voice in antarctic affairs. This voice perhaps is not as great a consideration in the present thinking of other polar organizations as it is with the Argentines, whose interest in Antarctica, and in particular the Palmer Peninsula area, is very strong. ...

Selection Of

In the past few decades, there has been lot of focus on the issue of sustainability. This has occurred due to the growing concerns related to climate change and the growing awareness about environmental concerns. Also, the competition at global level has led to the search for the most sustainable route in the industries. The current research work deals with the selection of green supplier in a Nickle coating industry based on certain weighted green attributes. For this purpose, a hybrid tool comprising of Fuzzy AHP (Fuzzy Analytical Hierarchy) and VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje) is used. The Fuzzy AHP is used for assigning proper weights to the selected criteria for supplier evaluation, while VIKOR is used for final supplier selection based on the weighted criteria. The three criterions for green supplier selection are, Ecological packaging, Corporate socio-environmental responsibility and Staff Training. The outcome of the integrated model may serve as a steppingstone to other SMEs in different sectors for selecting the most suitable supplier for addressing the sustainability issue.

This work interrogates federal character principle (FCP) in Nigeria. The FCP was designed to fundamentally address the striking features of Nigeria politics of intense struggles for power among the different ethnic groups in the country between the elites from the North and their Southern counterparts and the various segments, but the practice of FCP in Nigeria so far raises curiosity and doubts. Given the outcome of the interrogation, this research work discovered and conclude that federal character has not indeed achieve its objective in the Nigeria, the study finds that Ethnocentrism, Elitism, Mediocrity, Mutual suspicion amongst others accounts for some inhibiting factors of the FCP in Nigeria. Like many other provisions of the Constitution, the Federal Character principle was meant to correct some imbalances experienced in the past, but it has created more problems than it has attempted to solve. Rather than promote national unity, it has disunited Nigerians. There is an urgent need to use more of professionals and result oriented Nigerians to carry out national tasks, than to use unprogressive people due to this "Federal character" issue. Nigeria should be a place where one's track records and qualifications are far greater than just "where they come from" or their lineage if Nigerian truly want to progress.
