Multi-Modal Acoustic Flow Decomposition Examined in a Hard Walled Cylindrical Duct
Authors: Weyna Stefan , Mickiewicz Witold 
Published: March 2015

Abstract
Flow fields could be of great interest in the study of sound propagation in aeroengines. For ducts with rigid boundaries, the fluid-resonant category may contribute significantly to unwanted noise. An understanding of the multi-modal propagation of acoustic waves in ducts is of practical interest for use in the control of noise in, for example, aero-engines, automotive exhaust and heating or ventilation systems. The purpose of our experiments was to test the acoustic energy transmission of duct modes based on studies carried out by the sound intensity technique. Sound intensity patterns in circular duct are discussed of modal energy analysis with particular reference to proper orthogonal decomposition and dynamic mode decomposition. The authors try to justify some advantages of the sound intensity experimental research in this area. In the paper, the wide-band sound signal propagated from source approximated with loudspeaker in hard-walled duct is imaged using a sound intensity - based approach. For a simple duct geometry, the sound intensity field is examined visually and by performing a modal decomposition greater insight into the acoustic structures is obtained. The image of sound intensity fields below and above “cut-off” frequency region are found to compare acoustic modes which might resonate in duct.
In Memoriam Professor Jerzy Sadowski 1924-2014
Authors: Szudrowicz Barbara 
Published: March 2015

Abstract
Professor Jerzy Sadowski – outstanding Polish scientist, a specialist in acoustics – construction, industrial, architectural and environmental – passed away on 28th July 2014. Professor Jerzy Sadowski was born on 18th December 1924 in Augustów, in northeastern Poland. In 1946 he commenced studies at the Gdańsk University of Technology – initially at the Faculty of Architecture, to switch later to the Faculty of Electrical Engineering. The life of Jerzy Sadowski as a student was as complicated as the post-war history of Poland. Due to his involvement in an activity of illegal student organization, he was expelled from the university in 1949, with a ban on any further tertiary education. The ban had been lifted after a certain time which allowed him to recommence further studies, this time at the Warsaw University of Technology the Faculty of Communications, where in 1952 he obtained the diploma and title of Master of Science and Engineer. He received a lot of help from Professor Ignacy Malecki, the nestor of Polish acoustics. This certainly contributed to kindling the young engineer’s interest in acoustics, as a field of both knowledge and very important practical applications.
Dolphin-Inspired Target Detection for Sonar and Radar
Authors: Leighton Timothy , White Paul 
Published: March 2015

Abstract
Gas bubbles in the ocean are produced by breaking waves, rainfall, methane seeps, exsolution, and a range of biological processes including decomposition, photosynthesis, respiration and digestion. However one biological process that produces particularly dense clouds of large bubbles, is bubble netting. This is practiced by several species of cetacean. Given their propensity to use acoustics, and the powerful acoustical attenuation and scattering that bubbles can cause, the relationship between sound and bub-ble nets is intriguing. It has been postulated that humpback whales produce ‘walls of sound’ at audio frequencies in their bubble nets, trapping prey. Dolphins, on the other hand, use high frequency acous-tics for echolocation. This begs the question of whether, in producing bubble nets, they are generating echolocation clutter that potentially helps prey avoid detection (as their bubble nets would do with man-made sonar), or whether they have developed sonar techniques to detect prey within such bubble nets and distinguish it from clutter. Possible sonar schemes that could detect targets in bubble clouds are proposed, and shown to work both in the laboratory and at sea. Following this, similar radar schemes are proposed for the detection of buried explosives and catastrophe victims, and successful laboratory tests are undertaken.
Electric Vehicles and Urban Noise Control Policies
Authors: Maffei Luigi , Masullo Massimiliano 
Published: March 2015

Abstract
Limited Traffic Zone (LTZ) is a planning strategy that is more and more adopted by municipalities in Europe to improve their environmental conditions. It consists in the prohibition for traditional vehicles to circulate in specific areas. Although the main aim is to tackle air pollution problems, positive effects are registered in terms of reduction of noise annoyance and in terms of improved “quality of life” if specific conditions are respected. On the other side under the drive of the global market, the number of circulating electric vehicles in urban sites is also increasing. In the next years we expect to experience a new and not well-known urban soundscape.
In this paper is presented an overview of recent urban projects and policies that deal with noise control and how these experiences will match into the next years with the sound characteristics of new electric vehicles for private and public transportation.

Authors: Wawrzynowicz Adam , Krzaczek Marek , Tejchman Jacek 
Published: March 2015

Abstract
Airborne acoustic properties of composite structural insulated panels CSIPs composed of fibre-magnesium-cement facesheets and expanded polystyrene core were studied. The sound reduction ratings were measured experimentally in an acoustic test laboratory composed of two reverberation chambers. The numerical finite element (FEM) model of an acoustic laboratory available in ABAQUS was used and verified with experimental results. Steady-state and transient FE analyses were performed. The 2D and 3D modelling FE results were compared. Different panel core modifications were numerically tested in order to improve the airborne sound insulation of CSIPs.
Simulated Sound-Fields in a Multi-Configurable Auditorium
Authors: Bustamante Pedro , Girón Sara , Zamarreño Teófilo 
Published: March 2015

Abstract
In this work, simulation techniques have been implemented to study the sound fields of a multi-configurable performance enclosure by creating computer acoustic 3D-models for each room configuration. The digital models have been tuned by means of an iterative fitting procedure that uses the reverberation times measured on site for unoccupied conditions with the orchestra shell on the stage. The initial virtual acoustic model is validated by comparing the other monaural and binaural acoustic parameters measured in the room in terms of their perception differential threshold. The procedure is applied to the Maestranza Theatre of Seville, built for the Universal Exhibition in 1992. The spatial distribution of the acoustic parameters in the audience area of the venue by measured parameters and simulation mappings enables the establishment of three zones of acoustic comfort, and are corroborated by the values of the Ando-Beranek function which provide a global quality coefficient of each zone.
Acoustical Analysis of Enclosure as Initial Approach to Vehicle Induced Noise Analysis Comparatevely Using STFT and Wavelets
Authors: Błazejewski Andrzej , Kozioł Piotr , Łuczak Maciej 
Published: March 2015

Abstract
It is assumed in the paper that the signals in the enclosure in a transient period are similar to a noise induced by vehicles, tracks, cars, etc. passing by. The components of such signals usually points out specific dynamic processes running during the observation or measurements. In order to choose the best method of analysis of these phenomena, an acoustic field in a closed space with a sound source inside is created. Acoustic modes of this space influence the sound field. Analytically, the modal analyses describe the above mentioned phenomena. The experimental measurements were conducted in the room that might comprise the closed space with known boundary conditions and the sound source Brüel & Kjær Omni-directional type 4292 inside. To record sound signals before the field's steady state was reached, the microphone type 4349 and the 4-channel frontend 3590 had been used. The obtained signals have been analysed by using two approaches, i.e. Fourier and the wavelet analysis, with the emphasis on their efficiency and the capability to recognise important details of the signal. The results obtained for the enclosure might lead to the formulation of a methodology for an extended investigation of a rail track or vehicles dynamics.

Abstract
In the acoustic fatigue experiment for hypersonic vehicle in simulated harsh service environment on ground, acoustic loads on the surface of test pieces of the vehicle need to be measured. However, for the normal microphones without high temperature resistance ability, the near field sound measurement cannot be achieved. In this work, on the basis of previous researches, an acoustic tubes array is designed to achieve the near field measurement of acoustic loads on the surface of the test piece in the supersonic airflow with high temperature achieved by coherent jet oxygen lance. Firstly, the process of designing this acoustic tubes array is introduced. Secondly, the equality of phase differences at the front and at the end of the tubes is stated and proved using a phase differences test with an acoustic tubes array whose design is presented in this text; therefore, the phase differences of signals acquired by microphones can be directly applied to beamforming algorithm to determine the acoustic load source. Finally, using above mentioned acoustic tubes array, measurement of acoustic load, with and without a test piece in the supersonic airflow made by the coherent jet oxygen lance, is conducted respectively, and the measurements results are analyzed.

La question monétaire, l’une des seules relatives au rattachement de la Flandre wallonne au royaume de France par le traité d’Aix-la-Chapelle qui n’ait pas encore été étudiée, est le sujet de cet article. Après avoir établi la physionomie de la circulation monétaire et le cours des espèces pour les premiers mois de l’installation française, le programme de Colbert de « franciser » le monnayage dans cette contrée est présenté ainsi que les dispositions prises par la monarchie pour y parvenir, à commencer par la participation des représentants des autorités locales qui semblent déjà supplantés par les officiers parisiens.
Le monnayage de Louis XIV spécifique à la Flandre française (1685-1705). Catalogue raisonné des espèces frappées
Authors: Charlet Christian 
Published: March 2015

Les conquêtes territoriales dans le nord avaient entraîné le rattachement au royaume de « pays conquis » cédés par l’Espagne. Par dérogation à la règle qui imposait l’usage de la monnaie royale dans les nouveaux territoires, ces pays bénéficièrent d’une tolérance des espèces espagnoles malgré les décris royaux renouvelés. En 1685 toutefois, après y avoir songé à plusieurs reprises, le gouvernement royal mit en œuvre le projet du contrôleur général des Finances Le Pelletier de créer une série d’espèces d’argent spécifique aux « pays conquis » dite « pièces de Flandre », frappées de 1685 à 1705, un atelier monétaire étant spécialement ouvert à cet effet à Lille.
Die <i>Semeia</i> [tekens] in die Evangelie volgens Johannes
Authors: Schnelle Udo 
Published: March 2015

Die semeia in die Evangelie van Johannes word eerstens geanaliseer in verhouding tot soortgelyke wonderverhale, veral in die sinoptiese evangelies en ten tweede in verhouding tot die breër Johannese narratief. Duidelike ooreenkomste met sommige van die sinoptiese wonderverhale word bespreek. Dit lei tot die bevraagtekening van die sogenaamde ‘semeia-bron’-teorie. Opvolgend op hierdie diskussie word Johannes se eie interpretasie van die wonders nagegaan. Daar word veral aan die vervlegting van die wonderverhale met die teologie van Johannes aandag gegee, veral ten opsigte van die verhouding tussen die Vader en die Seun, geloof, die menslikheid van Jesus en die lyding van Jesus.The Semeia in the Gospel according to John. The semeia in the Gospel of John are analysed, first in relation to other similar miracle narratives, especially in the synoptic gospels, and secondly in perspective of the broader narrative of John’s Gospel. Clear links with some of the synoptic miracle narratives are discussed, questioning the ‘semeia source’ theory. This discussion is followed by a consideration of John’s own interpretation of the miracles, exploring the interwovenness of the miracle stories with the theology of John, especially regarding the relation between the Father and the Son, the humanness of Jesus, the passion of Jesus and faith.
’n Prinsipiële diskoers oor die epistemologiese fundering van die Pastorale Teologie: ’n Oproep tot reformasie
Authors: Janse van Rensburg Johan 
Published: March 2015

Hierdie artikel is as ’n huldeblyk aan prof. George Lotter by sy aftrede geskryf en uit erkenning vir sy bydrae tot die wetenskapsbeoefening van die Praktiese Teologie. Die artikel ondersoek die huidige konteks van die pastorale teologie. Aangesien epistemologiese keuses die metodiek en uitkoms van die pastoraat bepaal, is daar ’n dringende noodsaak om die epistemologiese invloede op die pastorale teologie te evalueer. Die artikel fokus op die epistemologiese dinamika wat die pastoraat verander het van ’n skriftuurlike fundering na ’n kommunikatiewe handelingsteoretiese en postmoderne narratiewe strategie. Die navorsingsvraag is: Is ’n reformatoriese terugkeer na ’n bybels-gefundeerde pastoraat teen die agtergrond van die epistemologiese invloede nog moontlik?As a tribute to Prof. George Lotter on the occasion of his retirement and to his contribution to practical theology, this article focuses on the current situation of pastoral theology worldwide but mostly in South Africa. Since epistemological choices determine the method and content of research on pastoral theology, as well as the practical implementation thereof, there is an urgent need to evaluate the influences on pastoral theology and the results of these influences. The article focuses on the epistemological dynamics that have changed pastoral theology from a scriptural approach to a discipline of communicative acts and a postmodern strategy of narrative pastoral counselling. The research question is: Is it still possible to have a reformed pastoral theology and pastoral counselling against the backdrop of these epistemological changes?

Authors: Bharadwaj Suparna , Moga Rebecca , Manninen Pirjo , Venkatraghavan Lakshmikumar 
Published: March 2015

AbstractPre-surgical embolization of vascular brain and spinal tumours is an effective method of reducing intraoperative bleeding. Many technological developments of the microcatheters and embolic materials that are used have led to better outcomes in tumour embolization. Pre-operative embolization has become a standard of practice in the management of many vascular brain and spinal tumours. Anaesthesiologists are generally involved with these procedures which may be performed with general anaesthesia, conscious sedation or monitored anaesthesia care. The choice of the anaesthetic technique usually depends on the patient characteristics, tumour location, vascularity of the tumour and most importantly the neuroradiologist and/or institutional preferences. There is limited information in the literature on the anaesthetic considerations for these patients. The aim of this review is to provide a brief overview of the indications, techniques, complications and relevant anaesthetic considerations for patients undergoing pre-surgical embolization of intracranial and spinal tumours.
Current neuromonitoring techniques in critical care
Authors: Ristic Anette , Sutter Raoul , Steiner Luzius 
Published: March 2015

AbstractEarly detection of secondary events is a major target of neuromonitoring in critically ill patients. Intracranial pressure (ICP) and cerebral perfusion pressure are the most widely accepted neuromonitoring parameters. Many studies have shown both to be related to mortality after traumatic brain injury. However, the benefit of ICP monitoring has not been established by a randomized controlled trial, and the efficacy of ICP-guided management has indeed been challenged. This review considers current neuromonitoring techniques in critical care medicine.

Authors: Yadav Amlendu , Pawar Mridula , Garg Rakesh , Banerjee Neerja 
Published: March 2015

Abstract
Introduction: Hyperbaric oxygen therapy (HBOT) is used to improve functional outcome following brain injuries. Different number of sessions of HBOT have been reported but the frequency of HBOT sessions in head injured patients has not been standardized. We planned this prospective randomized study with an aim to compare the neurological effects of 10, 20 and 30 sessions of HBOT in the head injured patients. Materials and Methods: After review board approval, this study was conducted in 60 head injury patients with Glasgow Coma Scale (GCS) score ≤ 9. All patients were resuscitated, stabilized and received neurological care according to institutional protocol. Patients were randomly allotted to–Group H10 (n-20)–which received 10 sittings of HBOT, Group H20 (n-20)–which received 20 sittings of HBOT, Group H30 (n-30)–which received 30 sittings of HBOT. GCS score was recorded after every 10 sittings and at 30 days from initiation of HBOT. Improvement Global rating and Glasgow outcome scale (GOS) were recorded after 30 days. Results: The maximum improvement in GCS scores was seen in group H30. The difference in the average improvement global rating scale was significant between group H10 and group H20, between group H10 and group H30 but was comparable between groups H20 and H30. The GOS was better after 30 sessions as compared to 10 sessions. Patients of all groups showed improvement in spasticity but group H30 showed a maximum improvement. Conclusion: A minimum of 30 HBOT sessions should be considered in head injury patients to show improvement with HBOT. Progressive improvement in GCS scores, GOS, spasticity, mood swings was better seen with increased number of HBOT sessions.
Cardiogenic oscillation induced ventilator autotriggering
Authors: Kaloria Narender , Gupta Akhilesh , Goila Ajay , Sood Rajesh 
Published: March 2015

AbstractCardiogenic oscillation during mechanical ventilation can auto-trigger the ventilator resembling patient initiated breadth. This gives a false sense of intact respiratory drive and determination brain death, even if other tests are positive, is not appropriate in such a situation. It will prolong the ICU stay and confound the brain-death determination. In this case report, we describe a 35 year old man who was brought to the hospital after many hours of critical delay following multiple gun shot injuries. The patient suffered a cardiac arrest while on the way from another hospital. After an emergency laparotomy, patient was shifted to Intensive Care Unit (ICU) with Glasgow Coma Scale (GCS) score of E1VTM1 and was mechanically ventilated. Despite absence of brainstem reflexes, the ventilator continued to be triggered on continuous positive airway pressure (CPAP) mode and the patient maintained normal oxygen saturation and acceptable levels of carbon dioxide. An apnoea test confirmed absent respiratory drive. Ventilatory waveform graph analysis, revealed cardiogenic oscillation as the cause for autotrigerring.
Fast Solution for Solving the Modified Helmholtz Equation withthe Method of Fundamental Solutions
Authors: Chen C. S. , Jiang Xinrong , Chen Wen , Yao Guangming 
Published: March 2015

AbstractThe method of fundamentalsolutions (MFS)is known as aneffective boundary meshless method. However, the formulation of the MFS results in a dense and extremely ill-conditioned matrix. In this paper we investigate the MFS for solving large-scale problems for the nonhomogeneous modified Helmholtz equation. The key idea is to exploit the exponential decay of the fundamental solution of the modified Helmholtz equation, and consider a sparse or diagonal matrix instead of the original dense matrix. Hence, the homogeneous solution can be obtained efficiently and accurately. A standard two-step solution process which consists of evaluating the particular solution and the homogeneous solution is applied. Polyharmonic spline radial basis functions are employed to evaluate the particular solution. Five numerical examples in irregular domains and a large number of boundary collocation points are presented to show the simplicity and effectiveness of our approach for solving large-scale problems.
Assess the Knowledge on Menopausal Self-care among Perimenopausal Women
Authors: Anjaly N , Philip T Anju 
Published: March 2015

ABSTRACT
Perimenopause which generally begins more than 5 years before the permanent cessation of menses, it is a time of transition characterized by unstable endocrine physiology and highly variable, unpredictable hormone profiles. The purpose of the study is to assess the knowledge on menopausal self-care among perimenopausal women in selected wards of Nayarambalam Panchayath, Ernakulam. Quantitative approach with descriptive survey design is used for the study. Sample consists of 120 perimenopausal women of 35 to 50 years, residing in selected wards of Nayarambalam Panchayath, Ernakulam. The knowledge regarding menopausal self-care is poor among 71% of perimenopausal women, average among 28% of perimenopausal women and 1% of them have good knowledge. Mean knowledge score is 8.04, SD is 5.09 and maximum score is 30. No significant association was found between knowledge and variables like age, educational status, family income and menopausal status. Perimenopausal women have inadequate knowledge on menopausal self-care. Findings of the study highlight the need of educational intervention for improving the knowledge of self-care among perimenopausal women.
